Thick Sheet Blister Forming Machine (Customized Type)

Design Idea

High Efficiency and High Quality Acrylic, PC, ABS, PE, PP, PS and other sheets can be formed with vacuum blister at one time, effectively avoiding air leakage during blister forming, thus reducing rejection rate and ensuring product qualification. This machine is mainly for thick rubber sheet blister into a uniform thickness of qualified products.

Product Analysis

According to the requirements of thick rubber sheet products, the sheet is heated and then molded once. 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 with photoelectric limit to reduce the scrap rate.

Blister Forming Machine Scheme

According to the requirements of the materials used, the mobile upper and lower double electric furnace infrared heating system is used to effectively heat the thick sheet materials. The temperature is controlled so that the materials are not completely cured and sagging. The lower die pneumatic system is started. The material is blister formed by matching the die and the sheet. The upper die system works as required to prevent the four corners of the formed products from cramping and deviation, after molding, the product is cooled by a large air volume fan. After this procedure, the demoulding function is started, the lower mold is lowered, the clip frame is raised, and the product is manually taken out.

semi-automatic program: manual sheet feeding-manual switch clip sheet pneumatic compression-semi-automatic electric oven baking sheet-electric oven exit-lower mold rise upper mold assist-plastic molding-fan cooling-lower mold drop demoulding-clip frame rise to take out the product (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. Molding mechanism: Adopt integral lifting hydraulic lifting design, and cooperate with cold-plated optical axis, oil-containing shaft 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 tubes of upper and lower double electric furnaces are used for uniform heating and can be driven separately. Temperature control adopts digital precise temperature control system, which makes the temperature of the heating area flexible and adjustable and has more power saving function. The electric furnace is made of stainless steel and is driven by an electric motor chain.

4. Electrical control system: The design adopts PLC program control, touch screen as man-machine interface, all English/Chinese input is intuitive and clear, and the operation is simple. The equipment is equipped with emergency stop switch to provide safety guarantee for production, and can store relevant data and production call.

5. Feeding system: The plate is manually placed in the clip frame, and then the sheet is clamped by the clip frame, and then the semi-automatic blister forming process is started.
