Description

Technical Field

[0001] The utility model relates to the technical field of plastic processing, in particular to a plastic extruder with a preheating mechanism. Background Art

[0002] Plastic processing is also called plastic molding. It is a general term for various processes that convert synthetic resins or plastics into plastic products. It is a large production sector in the plastics industry. Plastic processing generally includes plastic batching, molding, machining, joining, modification and assembly. The last four processes are carried out after the plastic has been molded into finished products or semi-finished products, also known as plastic secondary processing. In the process of plastic processing and molding, plastic processing extruders are usually required.

[0003] In the prior art, for example, Chinese patent number: CN217553075U discloses a cable processing plastic extruder with a preheating function, comprising a base, a driving mechanism fixedly connected to the top of the base, a working cylinder arranged on the top of the base, a discharging cylinder fixedly connected to the outside of the working cylinder, and an extrusion mechanism arranged inside the working cylinder. The utility model relates to the technical field of plastic extruders; the cable processing plastic extruder with a preheating function starts a driving motor, and the driving motor drives the first bevel gear to rotate through the driving shaft, and the rotation of the first bevel gear drives the auxiliary shaft to rotate through the second bevel gear. Whether the driving motor is running stably can be observed through the auxiliary shaft. If the driving motor fails and stops working, an external power source can be connected to the auxiliary shaft, and the driving shaft is driven to rotate through the auxiliary shaft, the first bevel gear and the second bevel gear, thereby preventing the raw material from cooling and solidifying inside the working cylinder and causing damage to the working cylinder.

[0004] However, it was found during use that the above patent did not have a material control structure inside the feed barrel, which resulted in the extrusion device not having the function of material control. When there is too much plastic, it is easy to cause blockage, thereby affecting the normal operation of the extruder. At the same time, the above patent directly uses a heating plate for preheating. After reaching the required temperature, the heating plate cannot stop and will continue to heat, which may result in a waste of electrical energy.
