Abstract

An extrusion device for polyamide production, comprising a single-screw extruder, a water tank is arranged on one side of the single-screw extruder, an inverted U-shaped frame is fixedly installed on the top surface of the water tank, and an inverted U-shaped frame is installed on one side of the U-shaped frame. There are two driving rollers in the front and rear directions. A moving plate is arranged on one side of the U-shaped frame. The first spring telescopic rods are respectively fixed on the front and rear sides of the bottom of the moving plate. The two ends of the two driving rollers are respectively connected to the corresponding one-way bearings The first spring telescopic rod, the front and rear sides of the inner wall of the U-shaped frame are fixedly installed with adjustment bars respectively, and the top surface of the adjustment bar is respectively in sliding contact with the movable end of the corresponding first spring telescopic rod. Compared with the existing device, firstly, this device can clamp one end of the heat insulation strip during the process of moving the transmission roller to the right, and then realize the automatic traction of the heat insulation strip; secondly, the pressure roller can automatically pull the heat insulation strip The strips are re-pressed into the water, allowing the water to cool and set the subsequent extrusion of the insulation strips from the single-screw extruder.

Description

technical field

[0001] The invention belongs to the field of heat insulation strip production equipment, in particular to a strip extrusion device for polyamide production. Background technique

[0002] After the heat insulation strip is extruded from the single-screw extruder, it needs to be cooled and shaped, and then pulled by the traction equipment to the next process for cutting. However, after the heat insulation strip is extruded by the single-screw extruder, one end needs to be manually It is extremely inconvenient to be pulled to the traction equipment. In addition, the cooling and shaping of the existing heat insulation strips are mostly water-cooled. Water contact is easy to cause the cutter to rust. Most of the existing traction devices directly drive the drive roller to rotate through the output shaft of the motor, and then drive the heat insulation strip for traction. This traction method is easy to cause the heat insulation strip to break. Contents of the in...
