Plastic extruder with good safety

Abstract

The invention belongs to the technical field of plastic extruders, and specifically relates to a plastic extruder with good safety. The plastic extruder comprises a base, an extruder body and a feeding hopper. A group of rotating shafts are uniformly distributed in the feeding hopper, the rotating shafts are uniformly distributed in the feeding hopper in a conical shape, and one end of each rotating shaft is connected with the feeding hopper in a rotating mode. The adjacent ends of the rotating shafts are fixedly connected with bevel gears, and the adjacent bevel gears are meshed with each other. One rotating shaft penetrates through the feeding hopper, extends out of the feeding hopper and is driven by a motor fixedly connected to the periphery of the feeding hopper to rotate. An auger blade is arranged on the periphery of the end, positioned in the feeding hopper, of each rotating shaft. Through transmission of the motor and the bevel gears, the auger blades are driven to continuously rotate and upwards convey and overturn plastic particles, the plastic particles are continuously and uniformly preheated and dried through hot air, and the working efficiency of the plastic extruder is improved.

Description

technical field [0001] The invention belongs to the technical field of plastic extruders, in particular to a plastic extruder with good safety. Background technique [0002] The screw extruder relies on the pressure and shear force generated by the rotation of the screw, so that the material can be fully plasticized and evenly mixed, and then shaped through the die. Plastic extruders can be basically classified into twin-screw extruders, single-screw extruders, multi-screw extruders, and screwless extruders. [0003] When the plastic extruder is in use, the barrel needs to be heated to melt the plastic in the barrel, but there is no protection at the barrel, which is likely to cause personal health damage to workers. [0004] There are also some technical solutions for plastic extruders in the prior art. For example, a Chinese patent with application number 2020102085692 discloses a plastic extruder barrel protection device and its plastic extruder, including a motor, a dec...

Problems solved by technology

[0007] In order to make up for the deficiencies of the existing technology, when the plastic particles are heated and extruded through the extruder in the prior art, due to the uneven size of the plastic particles and the existence of plastic powder with a small diameter after crushing, it is stored in the open air for a long time. Afterwards, it is easy to be damp and agglomerated, and the plastic particles need to be heated to prevent the plastic particles from clogging the feed hopper. However, in the prior art, artificial heating is usually used, and then the plastic particles with higher temperature are transferred to the feed hopper. Plastic particles are easy to spill and cause waste and burns, causing potential safety hazards. The invention proposes a plastic extruder with good safety
