Full-automatic Thick Sheet Blister Forming Machine (Customized Type)

Design Idea

Full-automatic Thick Sheet Blister Forming Machine can supplement PVC, PE, ABS, PET, PP, PC, PS acrylic and other sheets with vacuum blister forming at one time, effectively avoiding air leakage during blister forming, thus reducing scrap rate, and can produce automobile interior and exterior trim parts, supermarket supplies and electrical pallet products. Fully automatic production has the advantages of saving labor and improving production efficiency.

High efficiency and high quality can be used to form PE, ABS, PET, PP, PC, PS acrylic and other sheets with vacuum blister at one time, effectively avoiding air leakage in blister forming, thus reducing scrap rate and ensuring qualified products. The materials used for pallet products, automotive interiors and electrical lining products are more applicable, so as to produce qualified products with uniform thickness. The equipment design basically realizes unmanned operation, and fully automatic production is in line with international standards and meets environmental protection requirements.

Product Analysis

According to the requirements of the surface finish of your thick sheet products and the characteristics of products with large height and difficult to form, the sheet needs to be heated and then formed by a blister. The design adopts infrared anti-sagging and air-blowing supporting sheet technology, so that the sheet can be pre-blown upward during forming, so that the formed product can meet the requirements. After the mold is raised, it will be shaped with the help of the upper mold as required to prevent the phenomenon of right-angle tendon pulling and the uneven state of sheet forming. According to the situation that there are many varieties of products, it is troublesome and time-consuming to change the mold. The use of movable non-adjustable clip frame, molding blowing system through time control to reduce the scrap rate.

Blister Forming Machine Scheme

According to the requirements of the materials used by your company, the full-automatic manipulator adopts a mobile upper and lower double electric furnace infrared heating system to effectively heat the thick sheet material. The temperature is controlled in a state where the material is not completely cured and sagging. The sheet can be bulged up by air blowing technology, the lower mold oil pressure system can be started, the material is molded by fitting the mold and the sheet, and the upper mold system works as required, the four corners of the molded product will not be cramped or offset. After the molded product is cooled by a large air volume fan. After this procedure, the back blowing and demoulding function will be started, the lower mold will be lowered, the clip frame will be raised, and the full-automatic manipulator will send out the product.

Full-automatic program: full-automatic sheet loading-automatic switch clip sheet pneumatic compression-automatic electric oven baking sheet-electric oven exit-lower mold rise upper mold assist-vacuum start blister molding-fan cooling-lower mold drop demoulding-clip frame rise to take out the product-manipulator sends out the product into the sheet (cycle in turn).

equipment constitutes

1, fuselage structure: 100*100mm square tube welding is adopted to make the frame firmer and withstand pressure over 30 tons. And according to the need in the key parts of the bolt connection, easy to install, remove and repair replacement.

2, hydraulic mechanism: the whole lifting platform design, and with cold plating optical axis, oil bearing sleeve and synchronous rack. So as to smooth the lifting action, to achieve the upper and lower mold high precision anastomosis requirements.

3. Heating part: halogen tube is used for uniform heating, and digital precise temperature control system is used for temperature control, which makes the temperature of the heating area flexible and adjustable, and has the function of saving electricity. The electric furnace is made of stainless steel, driven by an electric motor chain or cylinder, and equipped with a temperature indicator to observe the temperature in the furnace.

4. Electrical control system: The design adopts French Schneider PLC program control, touch screen as man-machine interface, all English/Chinese input is intuitive and clear, and easy to operate. The equipment is equipped with emergency stop switch to provide safety guarantee for production.

5, full-automatic feeding system: the plate is built in by the automatic lifting platform, and after stepping up, the suction cup of the pneumatic manipulator is moved to the working position of the clip frame, and then the clip frame clamps the sheet, and then the automatic blister forming procedure is started.
