Cover making machine

Abstract

The invention provides a cover making machine, comprising a module pressure pan, a material cutting pan and an extruder. The module pressure pan is provided with a center rotating shaft and can rotate around the rotating shaft, the periphery of the module pressure pan is provided with at least one of module pressure unit which is equidistant to the center rotating shaft and is evenly distributed,the module pressure unit comprises a matched upper module and a bottom module with a hollow cavity, and the module pressure pan is provided with a lifting device which can control the module pressureunit to lift up and lift down and is provided with a demoulding device; the material cutting pan is provided with a center rotating shaft which is parallel with the center rotating shaft of the module pressure pan and rotates around the rotating shaft, the periphery of the material cutting pan is provided with at least one of cutting knifes, some part of the periphery of the material cutting pan is positioned between the upper module and the bottom module of the module pressure pan, the material cutting pan is also provided with a material pushing device for driving the cut roughcast materialonto the bottom module; and the extrude is provided with an extruding outlet which is upward and is positioned below the cutting knife of the material cutting pan. The cover making machine can continuously to manufacture plastic covers without injection points, has high production efficiency, less energy consumption, high use ratio of raw material, and no passageway waste material.

Description

technical field [0001] The invention relates to a cap making machine for making plastic caps. Background technique [0002] As an important part of the development of my country's packaging industry, plastic packaging is in a period of rapid growth. Nowadays, various beverages, cosmetics, medicines, etc. are mostly packaged in plastics, and the plastic covers of plastic packages often need to be produced separately. [0003] At present, injection molding machines are mainly used to process plastic covers. Injection molding machines use intermittent processing methods during processing, and their production efficiency is low. At the same time, they heat the plastic and need it to reach a molten state. However, if the mold cavity is filled and then cooled and molded, the energy loss is large; in addition, the injection molding machine often has a lot of runner waste, and its raw material utilization rate is not high, and the requirements for plastic raw materials are often st...

Problems solved by technology

[0003] At present, injection molding machines are mainly used to process plastic covers. Injection molding machines use intermittent processing methods during processing, and their production efficiency is low. At the same time, they heat the plastic and need it to reach a molten state. However, if the mold cavity is filled and then cooled and molded, the energy loss is large; in addition, the injection molding machine often has a lot of runner waste, and its raw material utilization rate is not high, and the requirements for plastic raw materials are often strict, so as not to block the injection port. The type of plastic raw material is very limited

On the other hand, the injection molding machine makes the mold cavity full of injection liquid through the injection port on the mold for the injection molding machine to inject molten plastic. When the injection molding machine is removed from the injection port, it often leaves an injection point in the plastic product made, which affects The appearance quality of its products
