Problems solved by technology

[0003] However, the structure of the filter screen inside the existing machine head is relatively simple, and the impurity particles after filtering will accumulate inside the machine head, which will still have a certain impact on the transportation of the molten material, and at the same time, the flow rate of the molten material cannot be controlled. The pressure instability phenomenon is easy to appear inside the machine head, which will have a certain impact on the molding pressure and compactness of the plastic, and affect the quality of the molding of the plastic product.

Abstract

The invention provides a plastic extruder device capable of effectively improving unstable pressure of a machine head, and relates to the technical field of plastic extruders. The plastic extruder device capable of effectively improving the unstable pressure of the machine head comprises a flow guide regulation and control mechanism, wherein a flow guide channel is formed in the flow guide regulation and control mechanism, a fluted disc is arranged in the flow guide regulation and control mechanism, a lead screw is arranged on the side face of the fluted disc, and a sleeve rod is in threaded connection with the surface of the lead screw. According to the plastic extruder device capable of effectively improving the unstable pressure of the machine head, a machine body and a movable screen plate are matched for use, impurities and unmelted particles in molten materials can be filtered, the movable screen plate, a fixed screen plate and a fixed scraper plate are matched for use, impurity particles on the surface of the movable screen plate can be cleaned, and meanwhile, conveying of the molten materials is not affected, impurity particles in the machine body are conveniently cleaned through cooperative use of a conveying screw and a discharging groove, and it is advantageously guaranteed that the pressure in the machine body is stable.

Description

technical field [0001] The invention relates to the technical field of plastic extruders, in particular to a plastic extruder device which can effectively improve the pressure instability of the machine head. Background technique [0002] Plastic extruder is a kind of plastic processing and extrusion equipment. When plastic extruder processes plastic, it needs to use the machine head to transport the molten material inside the machine head. When the material is transported, the pressure inside the body and the The blockage of the molten material, the physical properties of the rubber and other factors are related, which will have a certain impact on the stability inside the machine head. Therefore, when the existing machine head is in use, a filter screen and a perforated plate are designed inside to prevent the melting Impurities and unmelted particles in the state material are filtered, and the molten material is drained at the same time. [0003] However, the structure o...
