Fully automatic positive and negative pressure three station hot forming machine

1、 Equipment Overview

The JJSZY-600A high-efficiency programmable plastic positive and negative pressure thermoforming machine adopts the latest international plastic sheet forming technology. It is designed to integrate machine, electricity, and gas, and is controlled by a microcomputer and an industrial programmable logic controller (PLC). The entire system has an HMI (human-machine interface). Square tunnel type imported radiation heater, capable of forming concave and convex molds, laser blade punching, heating, forming, punching, and stacking in three stations, with advanced technologies such as simultaneous operation, is a plastic sheet forming equipment that completes sheet feeding, heating, forming, punching, and stacking in one go. A streamlined production line dedicated to hot forming and automatic product cutting, with reduced manual labor, convenient operation, improved production efficiency, strong reliability, and high degree of automation.

2、 Process technology

① Machine composition

The equipment mainly consists of a body, a vacuum forming system, a temperature control system, a vacuum system, a heating system, an air control system, an electrical and computer control system, a finished product punching system, a product decomposition and edge material self winding system, and other structural components.

② Process composition

Supply sheet → Transport sheet → First heating → Second heating → Third heating → Forming cooling → Cutting → Decomposing and stacking → Waste self winding system

Three stationsProduction line, operation plan: manual/automatic integrated switching effect, manual for easy sampling and control parameter settings.

3、 Equipment performance

1. Combining positive and negative pressure, products with the same material thickness have better texture, more stable weight, and uniform thickness than those produced by negative pressure vacuum forming.
2. The coexistence of positive and negative pressure functions ensures precise and stable product forming dimensions.
3. The feeding, heating, forming, punching, stacking, counting, and conveying are completed synchronously, and only one person is needed to package the product into the box, ensuring safety and hygiene without secondary pollution.
4. Forming, cutting, stacking, and feeding are all controlled by servo, ensuring precise and error free operation.
5. Adopting industrial control PLC and microcomputer human-machine interface control, the operation is precise and easy to operate.
6. Applying silicone oil, multiple vacuum and vibration demolding, up and down mold movement, up and down stretching, the product effect is better.
7. Automatic feeding system, with each roll weighing between 600-1500KG according to customer preferences.
8. At the same time, it can also customize five workstations: molding, punching side holes, punching bottom holes, cutting, and stacking; Customers can choose the functions of the equipment according to their own product needs.

4、 Technical parameters

The fully automatic positive and negative pressure three station thermoforming machine is suitable for thermoplastic materials such as ABS, PS, PE, PC, PP, PVC, PET, HIPS, PMMA, etc. with a thickness of 0.15-2.5mm,Processing products with high transparency, high stretching, shallow stretching, circular, square, irregular, double-sided stretching, and flanging,producibleDisposable fast food boxes, food boxes, fresh food trays, mooncake trays, instant noodle bowl covers, various cup covers, beverage cups, ice cream cups, jelly cups, packaging boxes, blister packs, flower pots, seedling trays, cosmetic liners, daily necessities vacuum packaging, pharmaceutical vacuum packaging, alcohol vacuum packaging, electronic vacuum packaging and other products.
