Description

Technical Field

[0001] The utility model belongs to the technical field of plastic extruders, and in particular relates to a plastic extruder which is convenient for feeding. Background Art

[0002] Plastic extruder is a device for processing plastics. The plastic extruder first needs to put in the raw materials, melt the raw materials, and then extrude them into shape through various methods. Plastic extruder is used to produce plastic parts of various shapes and functions, which are used in all walks of life. The raw materials used also include recycled waste plastics, which has made a certain contribution to environmental protection. During the operation of the plastic extruder, a series of ingredients need to be added through the feeding mechanism and mixed evenly before proceeding to the next process.

[0003] Patent No.: CN214773877U, mentions a plastic extruder that is easy to feed. The feeding hopper is divided into two parts, left and right, by a partition. Raw materials are added from the left side, and the claws and claw hooks are rotated to remove part of the air inside the raw materials, so as to avoid the situation where the raw materials contain too much air when they are poured in and affect the normal falling of the raw materials. The setting of the claws and claw hooks can make the feeding smoother, so as to avoid the situation where the untimely supply of raw materials affects the normal production of the plastic extruder. However, the device divides the feeding hopper into two parts, which will make the feeding of the feeding hopper slow, and the claws and claw hooks alone cannot mix the multiple ingredients added at the same time. Now there is an urgent need for a plastic extruder that is easy to feed to solve the above problems. Utility Model Content
