Abstract

The invention discloses a plastic extruder for producing chairs. The plastic extruder comprises a barrel of which one end is fixedly provided with a first driving motor, and the driving end of the first driving motor is connected to a first rotating shaft; one end, far away from the first driving motor, of the first rotating shaft penetrates the side wall of the barrel, and extends into the barrel; and one end, located in the barrel, of the first rotating shaft is fixedly connected to a screw conveyer. According to the plastic extruder disclosed by the invention, the inside wall of the barrelis provided with a thermal insulating layer, so that the operation of the first driving motor is prevented from being affected by high temperature of molten plastic colloid in the barrel; the barrel and the colloid in the barrel are cooled in time through spiral cooling pipes wound on the outside wall of the barrel, and the colloid in the barrel is prevented from being charred; and through the driving effect of the first driving motor, relative rotation between a first grinding disc and a second grinding disc is formed, thereby facilitating grinding of plastic particles in the plastic colloid,and the smoothness of plastic parts and the product quality are improved.

Description

technical field

[0001] The invention relates to the technical field of extruders, in particular to an extruder used for producing chairs. Background technique

[0002] A chair is a kind of furniture for daily life, a kind of sitting tool with a backrest and armrests. Due to the development of society, most of the parts of existing chairs adopt relatively cheap plastics. In the production process of plastic parts, they need to be extruded by extruder.

[0003] The extruder motor is an important part of the extruder, and is the prime mover of the extruder, providing the large thrust required by the extruder screw. When the extruder is working, the plastic in the barrel is a high-temperature molten plastic colloid, and the motor is directly connected to the screw of the extruder, which will have a bad influence on the temperature rise of the motor. At the same time, when the extruder is in continuous production for a long time, the rubber material will not flow smoothly in t...
