VACUUM FORMING MACHINE

VACUUM FORMING MACHINE
Plastic vacuum aspirator is controlled automatically by OG-1220C and OG-1220A type touch screen, electromechanical designed PLC, automatic control system of touch screen and adjustable and non-stop pressure gauge. water temperature regime in the first, the device is taken up journey mouth, heated, shaped, cooled, break the mold slice automatically completed once, and the plastic tray performance.

Relevant scope:
Mainly suitable for the production of plastic sheet products such as PS, HIPS, PVC, PET, PP, plastic tray production, packaging products in the interior, such as: medical injections trays, trays, trays, egg trays, electronic trays, food supplies, etc.

A, design idea
High efficiency, high quality of PET, PS, PP, PC, PVC, HIPS, flocking pieces and plastic sheet can be disposable vacuum plastic molding, design an effective avoid vacuum forming of air leakage phenomenon, pull piece of different length, thickness of the product not divide evenly, thus reducing the forming difficulty high reject rate of products, to ensure that products are qualified.

Second, the product analysis
According to your requirements: molding, sheet, design a vacuum forming of sheet after heating, and USES the top die high-speed power system from top to bottom, assist to complete the design of the size of high vacuum forming.
To improve the production efficiency and products quality requirements.
And suggested to choose the computer precise temperature control of heating system, combined with high precision servo motor to pull, to avoid the product thickness different size error is produced.According to the design requirements for the machine with functions of transverse once every piece of cut off.According to the requirements of your product size precision and the surface glossiness, need an aluminum precision mold.

Third, blister forming machine
Using electric infrared heating system to effective heating of plastic material, temperature control in do not make plastic material completely curing prolapse of state, to move the sheet by pull-tab motor to forming station, start the servo electric actuator system, auxiliary in power module, through the mould with sheet of plastic material vacuum forming, molding products are moved to the feeding platform, after the conveying system work, make a second operation sheet does not move back to offset, a cutting device length according to need to set manually or automatically, complete, blanking, thereby recycling program, high-speed production.

Advantages: fast heating, pull piece of precision, high production efficiency, scrap rate is low, suitable for all blister products and has the certain difficulty.

Four, the equipment
1, the fuselage structure: the machine is 12 welding, make it more solid frame, more pressure in 40 tons.And according to the need in the key parts adopt bolt connection, easy to install, disassembly and maintenance and replacement.
Four guide pillar 2, forming mechanism: the overall design, and cooperate with the cold plated optical axis, coaxial from mould the mold design.Smooth lifting action thereby, achieve lower die with sheet high precision requirements, the design tonnage of extrusion 2 tons, up and down the template is made of 20 mm steel plate, and grinding smooth, die size design and mould size is consistent, mold adopts the whole aluminum cold water circulating cooling mold.
3, feeding system: adopting the large automatic feeding frame, a feeding 50-300 kg/roll, and USES the biaxial alternate locking technology, motor has positive and negative functions, operation is convenient and slice.
, heating part 4: the ceramic brick infrared heat evenly heating, specular reflection heat insulation plate temperature, temperature control adopts digital electronic voltage regulator temperature control system, make the heating zone temperature is adjustable, flexible is more power saving function, so as to shorten the heating time improve production speed.
5, design of electrical control system: USES in PLC program control, super touch screen as human-machine interface, full Chinese input straightforward, easy to operate.Equipment installation stop switch, and to provide security for the production.
6, cutting system: adopting active two-way electric cutting design, high precision cutting products.
7, safety protection: blanking off in organic glass cover installation, safety design has effectively prevent operator wrong operation and strayed into dangerous institutions.
8, pull-in system: adopting servo 2.2-3 kw motor, precision error within 0.5 mm, can be used in a variety of blister, color printing, printing, blister sheet.
Five, the equipment function
1 state of flat die air float heating function can be realized to keep heating material plane to prevent material heating state thickness uneven because of prolapse
2 ejection device, difficult to demould easily parting, decrease the damage should be parting and scrap of the products.
3 secondary vacuum and vacuum time delay, according to different material in vacuum forming, can be arbitrary control.
4 chain security protection function to prevent misoperation cause damage to the machine.
5 mould machine can adjust the height, shorten the time of the mould, save the manpower cost.
6 from mould balance synchronizer function, improve the service life of equipment, reduce the product scrap rate.
