Extrusion head protection mechanism of extruder for plastic production

Abstract

The invention discloses an extrusion head protection mechanism of an extruder for plastic production. The extrusion head protection mechanism involves an extruder body, wherein a material conveying pipe is arranged inside the extruder body, a supporting mechanism is fixedly connected with the bottom of the material conveying pipe, the left side of the material conveying pipe fixedly communicates with a connecting pipe, the left side of the connecting pipe communicates with an installing pipe, and the left side of the installing pipe fixedly communicates with an extrusion head body. According to the extrusion head protection mechanism of the extruder for the plastic production, the extruder body, a sliding mechanism, a limiting mechanism, a guiding mechanism, the supporting mechanism, the material conveying pipe, the connecting pipe, a fixing shell, the extrusion head body, a installing block, the installing pipe, a fixing plate, a positioning column, a positioning groove, a discharging pipe, a sealing gasket, a first spring, a sliding groove, a sliding block, a clamping plate, a clamping groove, a clamping block, a shell body, a connecting plate and a limiting groove are arranged and matched in use, so that the problems of inconvenient installation of an existing extrusion head of the extruder for the plastic production and looseness caused by long-time use are solved.

Description

technical field [0001] The invention relates to the technical field of plastic production, in particular to an extrusion head protection mechanism of an extruder for plastic production. Background technique [0002] Plastic production, also known as plastic molding processing, is a general term for various processes that convert synthetic resin or plastic into plastic products. It is a large production department in the plastics industry. Plastic processing generally includes plastic ingredients, molding, machining, joining , modification and assembly, etc., the last four processes are carried out after the plastic has been formed into finished products or semi-finished products, also known as plastic secondary processing. [0003] Plastic needs to use extruder during production. The extruder relies on the pressure and shear force generated by the rotation of the screw, which can make the material fully plasticized and evenly mixed. It is formed through a die. The extrusion ...
