What are the applications and working principles of blister machines?

Blister machine (also known as thermoplastic molding machine) is a machine that absorbs thermoplastic coils such as PVC, PE, PP, PET, HIPS and other thermoplastic coils into various shapes of high-grade packaging boxes, frames and other products. Using the vacuum suction generated by the vacuum pump, the thermoplastic sheets such as PVC and PET after heating and softening are blistered into vacuum hoods, blister trays, blister shells, etc. of various shapes through molds.

The principle of blister molding machine: blister molding is also called thermoplastic molding, this molding process mainly uses the vacuum suction generated by the vacuum pump to heat and soften PVC, PET, PETG, APTT, PP, PE, PS and other thermoplastic sheets through the mold blister into various shapes of vacuum hood, or attached to the surface of various shapes of products. Blisters are divided into thin sheet blisters and thick sheets according to sheet thickness.

The main structure of the machine is composed of feeding, pulling, upper and lower electric heating furnaces, lower brakes, multi-functional adjustable sizes, lower die plates, upper molds, upper brakes, knife switches, slicing, discharging and vacuum devices.

The common products of thick film blister are: household appliance liner shell, luggage bag, display frame accessories, decoration, automotive interior, bumper, fender, beauty equipment, light box shell, toy car shell, industrial panel, advertising light box, blister logo, bathroom products, refrigerator liner and so on.

Main applications of blister machine:

1. Plastic packaging industry (blister packaging, plastics, batteries, toys, gifts, hardware, home appliances, electronics, stationery, decoration);

2. Food packaging industry (fast food boxes, fruit trays, biscuit boxes);

3. Pharmaceutical industry (pill packaging, tablet packaging);

4. Cooling water deflector plate of industrial upper cooling tower, etc.;

5. Three-dimensional relief patterns for decoration, plastic ceilings, wall panels, automotive materials, sanitary equipment and other manufacturing industries.

6. Suitable for the production of various color sheets: polyethylene PS, polyvinyl chloride PVC, plexiglass, ABS, polymethyl methacrylate; flocking sheets; Environmental protection sheet APET, PET, PP, etc.; photodegradable materials; Biodegradable materials and other plastic products.

Advantages of single mold blister machine:

1.The single-mold blister machine produced by our factory can not use sealing tape, using advanced air pressure technology, directly forming a vacuum of the plate that needs to be evacuated in the equipment, becoming a real automation, one person can completely replace the work of two people, saving the time and cumbersome operation process with sealing tape, saving time and effort.

2.When making the mold, it can save labor and materials, and the products made without being restricted by the yin and yang mold have no traces of pressure, and the edge of the light box or word is smooth and full, and the three-dimensional sense is strong.

3.High degree of automation, the plate can be placed directly in the machine, and a switch can be pressed to form a fully automatic work: heating - automatic constant temperature - automatic sealing - automatic suction.

Plastic - automatic cooling - automatic temperature stop - automatic stop blister.

The working mechanism of the plastic suction machine is that there is a small hopper on the raw material dryer, which is composed of a hopper, an induction switch, a mechanical air switch, a filter, a feed port, an air suction port, a suction pipe, and a feed pipe.

Host: Mainly the time relay controls the work and rest of the equipment. Components: motor, filter, air intake, suction device, induction cable and multiple sets of relays.

The working principle is: When there is no material in the small hopper, the mechanical air switch will fall down to open the induction switch, when the induction switch is turned on, the relay of the host is opened to let the motor start running, the motor operation drives the exhaust device, and begins to pass through the air filter to the small hopper, under the action of suction, the mechanical air switch closes the discharge port upwards to form a small hopper vacuum, the feed port has a pipe leading to the hopper, the raw materials begin to enter the small hopper, and the raw materials are isolated by the filter screen and will not be sucked into the direction of the motor. When the motor stops when the set operating time is reached, the mechanical air switch falls after the small hopper has no vacuum, the raw material falls into the dryer, and the cycle ends.

1. Blister machine refers to a kind of equipment that heats and softens thermoplastic materials, and cooperates with the corresponding mold to form a negative pressure blister mold.

2. The principle of the blister machine heats and softens the thermoplastic material, and then cooperates with the corresponding mold to carry out vacuum blister.

3. The use of the blister machine is simple and simple, and it is complicated to say that it is complicated, because the use of the blister machine requires the adjustment of temperature and time, and the blister factory will generally ask a professional start-up master to operate the blister machine production.

The molding blister machine absorbs the essence of the industry, and the essence of the absorption industry produced by our factory is constantly updated; The heating and forming machine produced by balancing technology and modern advanced guide rail positioning technology has the characteristics of powerful power, simple operation, energy saving and practicality. Adopting advanced hydraulic transmission technology, it is composed of two high-pressure cylinders and hydraulic stations to form a powerful hydraulic transmission system, and is equipped with advanced equipment. Practical and easy-to-grasp circuit control system makes the floating plate safe and stable; The maximum pressure can reach 12 tons, which is 2-3 times higher than the screw and pneumatic transmission pressure, and has a long service life.

The use of radiant heating, energy saving and high efficiency, automatic constant temperature, digital display, heating tube using thermal radiation tube, energy saving, large oven partition heating, from 0 to 400 degrees only takes about 10-15 minutes, every 3-5 minutes can soften the plate, the temperature rises to the use of temperature, the electricity per hour is about 15 degrees, the oven insulation effect is good, greatly saving electricity, reducing the production cost, the oven built-in plate can be moved, easy to replace and clean. The suction system is powerful, no need for stage vacuum, can always be in the ideal negative pressure state, more convenient to use. The power supply voltage is 380V and 220V (customized), which is easy to use in the factory and can also be operated in the store.

The molding operation standard is mainly divided into four processes: order taking, commissioning, mass production, and shutdown.

1.Orders:

Work assignment: After receiving the "production notice" from the production supervisor, the molding team will assign employees to produce on the designated machine according to the requirements on the order.

1..2. Machine inspection: "production notice" is handed over to the employee on duty first, after the employee on duty receives the order, first open the electric heating switch of the machine, preheat the forming oven, and check whether the electric heating pipe is bright, bright is normal, and whether the functional switch is normal, find that the switch is out of order, and the problem that can not be solved by yourself must be immediately reflected to the supervisor to assist in processing.

1..3. Mold pick-up: After the machine is checked normally, the shift will go to the mold warehouse to receive the required mold according to the mold number of "molding production".

After all the items are in place, you must check whether the number on the mold is consistent with the card, and check whether there are quality problems in the mold and upper mold. After checking and inspecting, you can sign the "mold entry and exit registration form" in the mold warehouse and take it out.
