The plastic sheet production line is a type of plastic machinery. Sheet machine, sheet production line, sheet equipment, sheet extruder

Operation method

1. Preheating of PVC plastic sheet production line: This is the process of heating the mold before starting up, and preheating is required to heat the mold.

2. Mold closing: Reasonable adjustment of the opening and closing stroke of the mold is beneficial for improving the demolding and feeding effects of the product.

3. Preheating of PVC plastic sheet production line: Steam enters the solid moving mold to preheat the mold, and at the same time, the condensed water and cold air during the retention period are discharged. Function: Raise the mold temperature and enhance the apparent fusion degree of the product.

4. Penetrating heating: improves the core and internal fusion properties of the product. Penetrating heating consumes and wastes steam significantly.

5. Heating by both parties: further enhance the heating effect and improve the surface quality of the product.

6. Temperature recovery (insulation): All valves are closed to fully utilize the residual heat of the mold, allowing the product to be insulated and heated. Beneficial for the surface fusion of the product and can effectively save energy (steam).

7. Vacuum cooling: Open the vacuum valve and use the vacuum pump to evacuate. Drain all residual heat and moisture from the mold and product, remove some foaming agent, and avoid product swelling. Creating negative pressure inside the mold is beneficial for demolding the product.

brief introduction

1. Horizontal three roll single machine sheet machine production line:

The unit is mainly composed of the main engine, screen changer, mold, tablet press, conveyor, traction machine, cutting machine, stacking rack or rewinding machine, etc;

The gearbox body is made of cast steel, and the gears are made of alloy steel and ground. Each lubrication point in the gearbox body adopts forced lubrication, and the lubricating oil is equipped with an efficient water cooling system.

The screw material is made of high-quality nitride steel 38CrMOA1A, which has been treated with nitride and sprayed with alloy on the surface.

The material of the barrel is made of high-quality nitride steel 38CrMOA1A, which has been treated with nitride and sprayed with alloy on the surface.

The raw materials that can be processed include PP, PE, PVC, PS, ABS, etc;
