Description

Technical Field

[0001] The utility model relates to the technical field of EPP molding, in particular to an EPP molding machine. Background Art

[0002] EPP is the abbreviation of expanded polypropylene, which is the abbreviation of a new type of foam plastic. EPP is a polypropylene plastic foam material, a highly crystalline polymer / gas composite material with excellent performance. With its unique and superior performance, it has become the fastest growing environmentally friendly new type of pressure-resistant buffer insulation material. In the EPP processing and molding process, an EPP molding machine is required. At this time, the EPP material can be placed in the EPP molding machine, and then the heating chamber of the molding machine is heated. At this time, the EPP board can be extruded. After the heating is completed, the EPP board can be formed and removed by cooling, thus completing the processing.

[0003] The existing Chinese patent application number 202222700527.8 discloses an EPP forming machine, including a forming machine body and a fixed plate, a bottom plate, a pressing plate and an operating groove, wherein the fixed plate is fixed on the upper surface of the forming machine body and is symmetrically distributed, and the bottom plate is fixed on the surface of the fixed plate on one side and is located above the forming machine body. Through the set pneumatic cylinder, when it is necessary to unload the EPP board after processing, the output end of the pneumatic cylinder can be started to push the push rod to move, and then the push rod can be moved by force to drive the push plate to translate inside, and the push plate pushes the EPP board in the operating groove to fall out. When the EPP material is placed in the operating groove and is squeezed by the pressing plate, the push plate can be reset by the pulling force of the push rod, achieving the effect of facilitating unloading and preventing the EPP board from being manually pushed out after processing, which affects work efficiency.

[0004] However, the EPP forming machine still has some shortcomings in actual use. For example, the EPP board is pushed out of the working groove only by using the push rod. Once the surface of the EPP board and the surface of the working groove are in a bonding state, the EPP board is easily damaged by the pushing force. Moreover, concentrating the pushing on one part is more likely to affect the flatness of the surface of the EPP board, thereby affecting the use effect and reducing the quality of the board.
