Description

Technical Field

[0001] The utility model relates to the technical field related to blow molding machines, in particular to a material extruding device for a blow molding machine. Background Art

[0002] A blow molding machine is a plastic processing machine that sprays out liquid plastic and then uses the wind force blown out by the machine to blow the plastic body into a mold cavity of a certain shape to make a product. This machine is called a blow molding machine.

[0003] During the use of current blow molding machines, plastic raw materials need to be conveyed into the screw extruder. However, the diameter of the hopper near the feeding port of the extruder gradually decreases, but the change is too fast, which causes the material to form a compacted solid. This is the so-called "bridging" phenomenon, which will prevent the raw materials from entering the extruder, resulting in the inability to convey the plastic into the extruder. The screw extruder will idle and is prone to damage, reducing production efficiency. In addition, the plastic raw materials need to be screened before use to remove impurities in the raw materials. Currently, the raw materials are generally screened manually, which is costly and time-consuming. Utility Model Content
