A plastic granule feeding machine

Abstract

The invention provides a plastic particle feeding machine, which comprises a barrel body, a heat-conducting plate is arranged on the inner wall of the barrel, the heat-conducting plate is provided with a cavity whose outer wall is open on one side, and the outer side of each opening is provided with an arc-shaped cover plate , the concave surface of the arc-shaped cover plate is provided with a heating pipe mounting seat and a heating pipe, and the heating pipe is located in the cavity; the top of the barrel is provided with a hopper, the barrel is provided with a stirring rod driven by a driving motor, and the lower part of the hopper is provided with a hopper. Ring-shaped plate, the top surface of the ring-shaped plate is provided with two guide rails, and the guide rails are provided with blocks for blocking the bottom of the hopper. The blocks are driven by a double-axis motor to move toward each other or move away from each other; located below the ring-shaped plate There is a spiral stirring blade on the stirring rod; it has the function of preheating the plastic particles, which can shorten the melting time of the subsequent plastic particles and improve the production efficiency; its heating structure is easy to disassemble and assemble, which is convenient for the maintenance and replacement of the heating structure; And the internal material can be stirred to facilitate heat transfer and provide good preheating effect.

Description

technical field [0001] The invention relates to the field of feeding machines, and more specifically, to a plastic particle feeding machine. Background technique [0002] Injection molding, also known as injection molding, is a molding method of injection and molding. At a certain temperature, the completely molten plastic material is stirred by a screw, injected into the mold cavity with high pressure, and after cooling and solidification, a molded product is obtained. Methods. This method is suitable for mass production of parts with complex shapes and is one of the important processing methods. [0003] In the injection molding process, the plastic pellets are generally transported and put in through the feeder. Most of the existing feeders do not have a preheating function, which leads to a long time for subsequent melting of the plastic pellets, prolonging the processing and production time.

Problems solved by technology

[0003] In the injection molding process, the plastic pellets are generally conveyed and put in through the feeder. Most of the existing feeders do not have a preheating function, which leads to a long time for subsequent melting of the plastic pellets, prolonging the processing and production time. Reduce production efficiency; although a small number of feeders have preheating functions, most of this type of preheating feeders have complex structures, difficult disassembly and assembly of internal heating devices, inconvenient maintenance and replacement, and inconvenient operation; and the heat between internal materials Inhomogeneous transfer, unable to achieve a good warm-up effect
