Abstract

The invention relates to a strip extrusion device for polyamide production, which comprises 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 face of the water tank; two transmission rollers in the front-back direction are arranged on one side of the interior of the U-shaped frame; a movable plateis arranged on one side of the interior of the U-shaped frame; first spring telescopic rods are fixedly installed on the front side and the rear side of the bottom face of the movable plate correspondingly; the two ends of the two transmission rollers are connected with the corresponding first spring telescopic rods through one-way bearings correspondingly; adjusting strips are fixedly installed on the front face and the rear face of the inner wall of the U-shaped frame correspondingly; and the top faces of the adjusting strips are in sliding contact fit with the movable ends of the corresponding first spring telescopic rods. Compared with an existing device, firstly, one end of a heat insulation strip can be clamped in the process that the transmission rollers move rightwards, and then automatic traction of the heat insulation strip is achieved; and secondly, the heat insulation strip obtained after automatic traction can be pressed into water again through a pressing roller, and theheat insulation strip extruded by the single-screw extruder subsequently is cooled and shaped through the water.

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...
