Abstract

The invention discloses an extrusion head replacing mechanism of an extruder for a plastic production. The extrusion head replacing mechanism comprises a body. An extrusion head is arranged on the right side of the body, auxiliary mechanism are fixedly connected to the front face and the back face of the extrusion head, first fixed blocks are fixedly connected to the top and bottom of the extrusion head, and first fixed bars are fixedly connected to the left sides of the first fixed blocks. By arranging the body, the extrusion head, the auxiliary mechanisms, a third fixed block, a third fixedbar, a fourth fixed block, an opening, the first fixed blocks, the first fixed bars, a clamping box, a second fixed block, a second fixed bar, a pulling mechanism, a fixed column, a fourth fixed bar and a pull ring matched in use, the extrusion head replacing mechanism solves the problem that an existing extrusion head which is too tedious to operate in a replacing process is inconvenient to replace. The extrusion head replacing mechanism of the extruder for the plastic production has the advantage of being convenient to replace the extrusion head, and improves the practicality of the plasticextruder.

Description

technical field [0001] The invention relates to the technical field of extruders, in particular to an extrusion head replacement mechanism of an extruder for plastic production. Background technique [0002] The extruder belongs to one of the types of plastic machinery. According to the flow direction of the head and the angle between the center line of the screw, the extruder can divide the head into a right-angle head and an oblique head. The screw extruder relies on the screw The pressure and shear force generated by the rotation can make the materials fully plasticized and evenly mixed. Through die molding, plastic extruders can be basically classified into twin-screw extruders, single-screw extruders and rare extruders. Multi-screw extruders as well as screwless extruders. [0003] Plastic production requires the use of an extruder, and the extrusion head of the plastic extruder needs to be replaced during use, but the existing extrusion head is too cumbersome to opera...
