The principle of ginning machine, the introduction of ginning machine

Leather roll ginning machine.

It is the use of the coefficient of friction.

The surface of the larger roller adheres to and drives the cotton fibers.

So as to achieve the purpose of separating from the cotton. The structure is simple, the manufacturing cost is low, the operation and maintenance are simple, and it is not easy to break the cotton fiber, which is suitable for processing fine staple cotton and long staple cotton.

and less ripe sub-cotton. Commonly used models are punch knife and hob cutter.

There are two formulas. Punch knife type roller ginning machine is to use a fixed knife to block the cotton on one side of the roller, and at the same time use a moving knife that reciprocates up and down to impact the cotton, so that it is separated from the fiber, the production efficiency is low, a width of 800 mm of the roller ginning machine can only process 30 40 kg of lint per hour. The hob type leather roller ginning machine uses a high-speed rotating hob (about 500 rpm) instead of a reciprocating moving knife to separate cotton.

A 1,000 mm wide disc cutter can process 200 kg of lint per hour.

Serrated ginning machine.

A machine that uses a disc saw blade that rotates at high speed (with a circumferential speed of about 12 to 13 m sec) to pull the cotton fibers through the gap between the ribs and separate them from the cotton. There are two types: brush type and air flow type. Its main working parts include flower feeding roller, flower cleaning mechanism, ginning work box, ginning rib, saw blade cylinder, brush drum or air flow nozzle, cotton collection box, etc.

The cotton is fed into the flower cleaning mechanism by the flower feeding rollers arranged in pairs, and then enters the front box of the ginning machine, and is thrown to the saw blade by the cotton roller. Large debris such as bell shells leaked, and the cotton was hooked by the serrations and brought into the ginning work box. The saw blade rotates rapidly, driving the cotton that pulls each other to form a rotating cotton roll.

The serration hooks the fiber to rotate, and after passing through the gap of the adjacent ginned ribs, the cotton fiber is brushed down by the brush drum (or air flow) and sent into the cotton collection box; The cotton is blocked by the ribs, moves down along the rib surface between the two saw blades, and is discharged out of the machine through the cotton comb. The production efficiency of the sawtooth ginning machine is related to the shape of the ginning box, the rotation speed of the cotton roll, the tooth shape and speed of the saw blade. Therefore, the main way to improve the sawtooth ginning machine is to reduce the movement resistance of the cotton rolls, and at the same time increase the speed of its surface movement to speed up the discharge of the cotton.

Generally, an 80 saw blade ginning machine can process about 400 kg of lint per hour, which is equivalent to the production efficiency of 10 800 mm roller ginning machines, and can also save 40% of energy consumption. The disadvantage is that the damage to cotton fibers is greater, and it is not suitable for processing fine staple cotton and long staple cotton, and the saw blade needs to be sharpened and replaced frequently. The sawtooth ginning machine produced in China uses a standard saw blade with a diameter of 320 mm and a blade spacing of millimeters.

Mild steel was successfully adopted at the end of the 70s.

Soft nitriding surface treatment.

The new process increases the life of the saw blade by 50% and reduces production costs.

There are many types of leather roll gimpellers. The commonly used is the punch type leather roll ginning machine, and its structure and working principle are shown in Figure 1. When the seed cotton is fed to the cottonseed grid at the front end of the push flower board, the push flower board moves back and forth, and the seed cotton is pushed to the surface of the leather roller between the fixed knife and the moving knife, and the fixed knife has the skin roller.

Appropriate pressure, the moving knife relies on the rotation of the crankshaft to reciprocate up and down, with the push plate to impact the seed cotton, the surface of the rotating roller is rough and elastic, the long fiber on the seed cotton is pulled to the fixed knife edge, attached to the surface of the roller to turn out, fall into the cotton box, the cotton seed is blocked in the fixed knife edge, and falls down through the cottonseed grid. Because the leather roller ginning machine relies on the rotation of the leather roller to pull the cotton fiber, the force is relatively gentle, it is not easy to pull off the cotton fiber, and the nep and cable silk are less, and the ginning is ***, so it is suitable for processing long-staple cotton, but the work efficiency is low, and the lint color is poor.

The leather roller of the leather roller ginning machine is generally lined with the outer wood of the steel shaft, and the outer layer is mainly made of old tires or adhesive strips, and it can also be wrapped tightly with degreased cowhide or cowhide rubber belt. The grade of lint rolled is related to the friction coefficient of the roller material. The length of the roller of the commonly used roller ginning machine has specifications such as millimeters, the first two kinds are generally used for the purchase of cotton when the clothing is used for trial rolling, and the last three kinds are used to process long-staple cotton and low-grade cotton.

In some countries, there are also larger roll-up gimpellers (1016 1232 mm roll-length), hob-type roll-type roll-up gin and double-roll double-punch gin to increase productivity. The hob type leather roller ginning machine mainly uses the hob to replace the moving knife of the punch type leather roller ginning machine, so that the output is greatly improved, and it is mainly used for processing cotton with a fiber length of more than 32 mm.

There are two types of sawtooth ginning machines commonly used: brush type and air flow type. The main component of the sawtooth ginning machine is the saw blade roller, which is mounted on the shaft at intervals by several saw blades and spacer rings, and is equipped with pressure rings at both ends, which are fixed with nuts. The speed of the serrated roller is 700 850 rpm.

Generally, the diameter of the saw blade is 320 mm, the thickness is 1 mm, the number of teeth is 304 teeth, and the tooth angle is 20°. The productivity of a sawtooth ginning machine is often expressed in terms of lint output per hour per blade – hourly output.

The development and use of ginning machine The main content of the purpose and significance of the research The development status of the ginning machine The concept of the ginning machine The role of the ginning machine The composition of the ginning machine The working process of the ginning machine The social benefits and advantages and disadvantages of the ginning machine The purpose and significance of the study With the popularization and use of lint cleaning machine in China, the requirements for the productivity of the ginning machine are getting higher and higher, in order to adapt to this situation and improve the productivity of ginning, it is necessary to determine the mechanical construction characteristics of the productivity of the ginning machine (such as the geometry of the working box, the cross-sectional area of the sawtooth, The diameter of the saw blade), the process parameters, the feeding speed and the properties of the processed seed cotton (grade, impurity content, moisture content, coating content, etc.) were studied separately. Among them, the working box is the heart of the sawtooth ginning machine, and its structural form has a great impact on the productivity of the ginning machine, which is one of the main factors determining the productivity of the ginning machine. Therefore, it is very necessary to study the sawtooth ginning machine.

With the development of science and technology, the application of cotton gin in people's lives is becoming more and more extensive, and the quilts we usually use, including the cotton used in the greenhouse quilts, are made of pure cotton produced by the ginning machine. Therefore, the current demand for ginning machine is still relatively high. The composition of the flower machine The ginning machine is divided into several components, including the clear flower, the working box and the back box, of which the clear flower part is used to feed the cotton quantitatively, remove small stones and other debris, and use the clear flower thorn roll to loosen the cotton to facilitate processing.

The composition of flower cleaning includes flower feeding roller, flower thorn roll, rack roller, grating frame, miscellaneous auger and so on. Then the cotton arrives at the work box. The working box is composed of sawtooth roller working box ribs, shell blocking ribs, small thorn rollers, etc., and some have seed discharge tubes, stiff blue and other components The composition of the tie flower machine The working box is the core component of the brush sawtooth ginning machine, which requires a high processing surface finish, and the cotton forms a cotton roll here, and the long linter is extracted through the sawtooth and the shell blocking rib, the cotton seed is separated, and the processed cotton is sent to the baler through the pipeline for packaging, and the short linter is brought to the back box by the sawtooth and sent to the cotton collection box for processing, and the cotton seed can also be extracted again by the stripping machine.

The working process of the ginning machine The process of sawtooth ginning The seed cotton is fed into the cotton storage box after the initial opening and removal of impurities by the multi-drum cotton cleaning machine, and enters the front box along the cotton board through the cotton feeding roller and the cotton cleaning drum. The front box is equipped with mechanical parts such as cotton barbed roller and shell blocking ribs, and the saw blade of the saw blade drum stretches out the gap of the shell blocking rib and contacts the seed cotton in the front box, and the seed cotton relies on the cotton pulling roller to the saw blade roller. When the saw blade drum rotates, the saw blade hooks the fiber through the shell ribs.

A type of cotton processing machinery. The machinery for separating lint from sub-cotton. It is required not to damage the quality of cotton fibers and cotton in the ginning process. There are two types of commonly used serrated ginning machines and leather roller ginning machines.

Let me talk about the ginning process: first clear the flower - ginning - cotton bale. At the same time, the cottonseed is stripped.

Ginning loom is referred to as ginning net machine, also known as pre-bending forming net machine, embossed mesh machine, called textile machine in ancient times, is an important means of production in the textile industry. The main use is for the production of ginning mesh.

It is a new patented cotton tie-up machine, which is a tie-flower machine with 2 skin rollers. No vibration, low noise, power saving, high output!

It is a new patented cotton ginning machine, which is a cotton ginning machine with two skin rollers. The traditional ginning machine is a leather roller, which is noisy and has low output; The double-roller cotton ginning machine is a bold improvement on the basis of the single-roller ginning machine, which doubles the output without increasing the power, and has no vibration, low noise, high output, power saving, and maintenance costs. Especially suitable for small and medium-sized cotton ginning plants!

The former is more flat and the latter is more cluttered.
