Extrusion device for producing color master batches

Abstract

The invention discloses an extrusion device for producing color master batches. The device comprises a shell and a hopper, wherein the hopper is located at the top of the shell; the hopper is of a conical structure; a feeding hole is formed in the top of the shell; the hopper is fixedly connected with the feeding hole and communicates with the feeding hole; a spiral rod is arranged in the shell; arotating motor is arranged outside the shell; an output shaft of the rotating motor is fixedly connected with the spiral rod; two supporting plates are fixedly installed at the top of the shell; thetwo supporting plates are located on the two sides of the hopper; and the tops of the two supporting plates are fixedly connected with the outer wall of the hopper. According to the extrusion device for producing the color master batches, a first baffle and a second baffle are arranged at the outlet of the hopper, the first baffle and the second baffle are not located on the same horizontal plane,thus the system load caused by continuous feeding of the extrusion system can be effectively avoided, and when the first baffle cannot be closed completely, the second baffle can be moved from the reverse direction to compensate a gap, so that the outlet of the hopper can be effectively closed and opened.

Description

technical field [0001] The invention relates to the technical field of extrusion devices, in particular to an extrusion device for producing color master batches. Background technique [0002] Extrusion devices can be divided into continuous extrusion and discontinuous extrusion according to the type of function. Plastic extruder is also a kind of plastic machinery. According to the angle between the flow direction of the head and the center line of the screw rod, the extruder divides the head into oblique head (120 degree included angle) and right-angle head. The shell of the machine head is fixed on the machine body with bolts. The mold inside the machine head has a core seat and is fixed on the inlet port of the machine head with a nut. The front of the core seat is equipped with a core, the core and the core seat There is a hole in the center for the extrusion system through the core wire extrusion system, including the screw, barrel, hopper, head, and mold. The plasti...

Problems solved by technology

The shell of the machine head is fixed on the machine body with bolts. The mold inside the machine head has a core seat and is fixed on the inlet port of the machine head with a nut. The front of the core seat is equipped with a core, the core and the core seat There is a hole in the center for the extrusion system through the core wire extrusion system, including the screw, barrel, hopper, head, and mold. The plastic is plasticized into a uniform melt through the extrusion system, and in the process Under the established pressure, the extruder head is continuously extruded by the screw rod, and the outlet of the hopper in the existing extrusion device often cannot be opened or completely closed during the process, resulting in excessive load on the device and reducing the service life of the device. For this reason we propose an extrusion device for the production of masterbatches
