What are the classifications of wood chippers and what are the advantages and disadvantages of each

Wood chippers are divided into two categories: stationary and mobile according to the way of movement: stationary type is mostly used in factories; The mobile type is generally used in forest areas and mountain farms. According to the structure of the working parts, there are two types: drum chipper and disc chipper, and there are two types of inclined feed and flat feed according to the feeding method.

Wood chipper is divided into three categories: coarse crushing, medium crushing and fine crushing according to the size of the processed product, as for the advantages, it is recommended to search for Rongfeng wood chipper, consult and you will know, there are too many contents, so I will not list them one by one.

Summary. Hello dear dear, wood chipper blades should be made of high-quality steel.

Hello dear dear, wood chipper blades should be made of high-quality steel.

What is the appropriate hardness of the blade.

The relevant information is as follows, wood chipper blade related manufacturers recommend that you choose Jinghua Machinery.

I'm asking about the material.

The hardness of the blade is similar to that of alloy hardness and steel. In general, the blade of the chipper is made of alloy tool steel, and after professional heat treatment, the hardness of the knife edge is HRC55-58°, which must ensure that the cutting edge is sharp and wear-resistant for a long time, so as to ensure the quality and production efficiency of the cutting chips.

Which alloy tool steel is it exactly.

Specifically, it is steel with a carbon content of 2% and titanium alloy processing tool steel, which has high strength, good corrosion resistance and high heat resistance.

Can you tell me a specific grade? Thank you!

The blade is made of 1mm titanium alloy edge.

That's an inlay insert?

Kiss, it is an inlay alloy blade.

The main types of wood cutting:

1. Sawing: the most widely used in wood processing. Saws include circular saw blades, band saw blades, frame saw blades, wire saw blades, and chain saws (for cross-cutting only), etc., which are multi-edge cutting tools.

Each tooth is a cutting edge, which has a front (front of the teeth), a back (back of the teeth) and two sides. The intersection of the front and back is called the slip and the main edge, and the intersection of the front and two sides is the two side edges. The space between the two teeth is the cogging.

Circular sawing is a rotary movement; The working section of the band saw is cut in a linear motion; Frame sawing is a linear reciprocating motion, and the feed makes most of the blind motion a linear motion. There are two kinds of cutting directions: longitudinal section and cross-section, and can also be used for grooving and tenoning.

2. Planing: The cutting tool planer and the workpiece move in a relative linear motion to complete the cutting process at one time. The planer or manually operated planer used in production is mostly used to process the plane or plane out the notch, line angle, etc.; Mechanical planers have crank linkages, track- or chain-driven planers, wood planers for making wood wool, and veneer planers, among others.

Planing is characterized by the fact that one of the workpiece and the cutting tool must be fixed and combined with the other to complete the cutting and feed movements. Most planing machines hold the workpiece in place, and the cutting tool performs both cutting and feed movements. The planing method is inefficient, but it is difficult to replace it with other cutting methods because the kinematic unevenness that occurs when the rotating tool is machined on the machining surface can be avoided on the machining surface.

3. Milling: The cutting tool is a milling cutter, which can be used to process planes, forming surfaces, carved surfaces, forming rotary bodies, etc., as well as milling tenons, grooves, etc.; Timber can also be milled into process chips, logs can be cut into squares and for raw panels. The milling cutter head is divided into three basic types: cylindrical, conical and face milling according to the different position of the cutter edge relative to the axis of the milling cutter head.

and dates. Milling is circumferential milling when used for plane machining, and because the surface obtained by machining is similar to planing processing, it is customary to call the milling cutter and milling machine of circumferential milling to process the plane as planer cutter and planer. The milling cutter makes a high-speed rotary motion during the cutting process. In addition to processing parts such as forming rotary bodies, the feed is mostly linear motion.

The trajectory of the cutting process synthesized by the two is a cycloid.

This creates a corrugated kinematic unevenness on the machined surface. Circumferential milling is divided into down-milling and up-milling, and the milling tool rotates against the feed direction of the workpiece for up-milling, and vice versa. Conventional milling is usually used for planers and four-sided planers, and climb milling is generally used for lumber chipping machines.

<>1) Chipper typeThe disc chipper is suitable for the production of raw material chips with large scale and large log diameter, and is equipped with a screening machine and a re-shredder. The drum chipper is suitable for small and medium-sized fiberboard manufacturers, and the raw material is to cut small diameter wood, branch wood, and the skin of the wood scraps. The lower part of the drum chipper is equipped with a sieve plate, and the cut wood chips can no longer be screened.

2) The quality of raw materials directly affects the quality of wood chips, so it is required that the raw materials should be the best shape, with a certain moisture content, no decay and less skin content. The moisture content of the raw material should not be less than 35%, otherwise it will not only cause an increase in the amount of chips, but also high power consumption, and will also shorten the service life of the cutting tool. The epidermis of the bark is mainly bast fibers, which belong to colloidal matter and have more content of pectin, sand and gravel, silice, etc.

When cutting, not only the amount of chips is large, but also the tool wear is serious.

3) The choice of cutting tools: The sharpness of the cutting tool directly affects the quality of the chipping. There are two kinds of flying knife blades: single edge and double edge, the grinding angle of the blade should be determined according to the material of the raw material to be cut, when cutting hard or frozen materials, the grinding angle should be large, and the grinding angle of the tool for cutting soft materials should be small. In this way, good cutting quality is guaranteed and energy consumption is reduced.

In order to ensure that the blade edge is sharp, the blade is required to be sharpened and replaced regularly, under normal circumstances, the flying knife should be replaced every 4 8h, and the bottom knife should be replaced every half a month.

4) The length and thickness of the raw material of the blade are determined by the installation position and angle of the blade, and the width of the blade is formed by natural rupture, which depends on the shear strength of the raw material, which is generally slightly smaller than the length of the chip. Therefore, the installation requirements for the blade are high, and it is an adjustment technology that cannot be ignored, whether it is a drum chipper or a disc chipper, all blades are required to extend the same amount, and the distance between the flying knife and the bed knife is accurately maintained.

Wood chipper, also known as wood chipper, wood chipper, wood chipper, wood chipper is currently more commonly used equipment for wood processing, under different production conditions need to choose different wood chipper equipment, so what are the classifications of wood chippers?

Wood chippers are mainly divided into disc wood chippers and drum wood chippers according to their working principles.

Brief introduction. Drum chipper series products are special equipment for the production of wood chips, this product is widely used in particleboard factories, medium and high density fiberboard factories, straw plants, biopower plants, wood chip factories and other industries and manufacturers in the production of the first choice of equipment. This product has advanced structure, high quality of cutting sheet, light adaptability of raw materials, and convenient operation and maintenance.

The main raw materials for cutting are small wood, timber harvesting, processing residues (such as branches, branches, bark, slats, round wood cores, waste veneer, etc.), and can also be used to cut non-wood raw materials (such as sugarcane, reeds, bamboo, etc.).

The drum chipper is composed of the machine body, knife roller, upper and lower feeding rollers, conveyor belt, hydraulic system and other parts. The machine body is welded with high-strength steel plate, which is the supporting foundation of the whole machine. Two or three or four flying knives are installed on the knife roller, and the flying knives are fixed on the knife roller through the pressure block with specially manufactured flying knife bolts.

Depending on the thickness of the raw material to be cut, the upper feed roller assembly can float up and down within a certain range with the help of a hydraulic system. The cut qualified sheet falls through the screen hole and is discharged from the bottom, and the large sheet will be cut in the machine.

Hydraulic system: supplied by the oil pump to the oil cylinder, the cover can be activated, which is convenient for the replacement of the blade; During maintenance, the feeding roller assembly can be lifted to facilitate the adjustment of the gap between the flying knife and the bottom knife and the disassembly and assembly of the comb plate. Disc chippers are divided into the following according to the number of knives on the cutterhead:

There are two types: ordinary chipper (4-6 knives) and multi-knife chipper (8-6 knives). There are two types of chipper feeding methods: inclined feeding and flat feeding (or horizontal feeding). The chipping of long logs is generally fed with a flat mouth, and the chipping of short logs and barks can be fed with an oblique mouth or a flat feeding.

Chipper This series of disc chippers has compact structure, reasonable layout, easy installation, convenient operation and maintenance, and high production capacity; When cutting logs, the wood chip quality is high, and the length of the wood chip can be adjusted freely within the specified range, which is the most advanced disc chipper in China.

1. Wood chipper: Wood chipper is widely used in the preparation section of the production process of textile, papermaking, pulping, wood-based panel and other industries. The main cutting materials of the machine, such as logs, small wood, bamboo, board leather, branches and felling secondary fuelwood residues, are high-quality industrial wood chips with uniform length, smooth incision and uniform thickness.

The wood chipper is suitable for trees with a diameter of less than 120 mm and bark with a width of less than 160-180 mm and the scraps of the barking machine, but the machine is too thick (more than 350mm), too fine (less than 30mm), too short (less than 250mm), too thin (less than 5mm) and irregular raw materials (undispersed stumps, branches, etc.) are not sufficient, or only cut off the raw materials on the original basis. For the slicing of bamboo with a wall thickness of less than 5mm, it is not sufficient, and has the function of layered cutting.

2. Disc chipper: Disc chipper is a kind of wood chipper, which is a special wood chipper used to produce high-quality wood chipsThe disc chipper is a special equipment for the preparation of high-quality wood chips, which is suitable for paper mills, chipboard mills, fiberboard mills and wood chip production bases.
