Plastic extruding machine for plastic welding

Abstract

The invention discloses a plastic extruding machine for plastic welding. The plastic extruding machine comprises a melting device. The melting device comprises a main motor, a material conveying hopper, a heating pipe, a material conveying screw and a plastic forming mold. A position adjusting device used for adjusting the position of the melting device is arranged on the lower portion of the melting device. The position adjusting device comprises a fine adjustment device used for adjusting the front-back position of the melting device, an angle adjusting device used for adjusting the included angle between the axis of the heating pipe and the horizontal line, a rough adjustment device used for adjusting the front-back position and the left-right position of the melting device, and a transmission device used for making the whole plastic extruding machine to move. The position of the plastic forming mold relative to a welding joint can be adjusted conveniently, flexibly and accurately, and the plastic extruding machine is suitable for plastic welding and used is used for crushing, softening, melting, exhausting and extruding of plastics.

Description

technical field [0001] The invention belongs to the field of extruders, in particular to an extruder used for plastic welding. Background technique [0002] The existing extruder includes a hopper, a heating pipe, a feeding screw, a main motor, etc. The plastic particles fall into the heating pipe from the hopper, and the feeding screw rotates under the drive of the main motor to make the plastic particles in the heating pipe flow toward the outlet end. Moving, the plastic particles are heated and gradually melted in the heating tube, and then extruded to the welding position through the plastic molding die to realize the crushing, softening, melting, exhausting and extrusion of the plastic. [0003] In the existing technical solutions, there are the following deficiencies: 1. When the plastic molding die of the extruder moves to the welding position, the position of the extruder needs to be constantly adjusted, and the extruder with a certain weight is time-consuming and la...

AI Technical Summary

Problems solved by technology

[0003] In the existing technical solutions, there are the following deficiencies: 1. When the plastic molding die of the extruder moves to the welding position, the position of the extruder needs to be constantly adjusted, and the extruder with a certain weight is time-consuming and laborious to move by manpower. And it is impossible to flexibly and accurately adjust the position of the plastic molding mold relative to the welding seam

[0004] 2. Directly extrude the melted plastic from the plastic molding die to the welding position, the quality of the formed weld is poor and cracks are prone to appear

[0005] 3. The heating temperature of the entire heating tube is usually set at a high temperature, which consumes a lot of energy

[0006] 4. Due to the long-term continuous and uniform delivery of high-temperature plastic melt, the plastic molding mold is prone to deformation, resulting in welds that do not meet the requirements. When the plastic molding mold is damaged, the plastic molding mold and the heating tube need to be replaced as a whole , high production cost
