Plastic corrugated pipe molding machine

Abstract

The present invention relates to a plastic corrugated pipe processing device, particularly to a plastic corrugated pipe molding machine. The technical scheme comprises that the plastic corrugated pipe molding machine comprises a motor, a material feeding device, a heating device, an extrusion device, a cooling device, a first molding device, a traction device, and a cutting machine, wherein the cooling device comprises a cooling water tank, a molding module, a water outlet and inlet pipe and a vacuum pipe, the water outlet and inlet pipe is arranged on the bottom of the cooling water tank, and is connected with an external water tank, and cold-hot water circulation is formed through the motor. According to the present invention, the traditional water pipe spraying cooling structure is not adopted, the water outlet and inlet pipe arranged on the bottom of the water tank and connected with the external water tank is adopted, and water is directly injected into the cooling water tank through the motor during cooling, such that the whole molding module part is completely immersed into water to carry out cooling heat dissipation.

Description

technical field [0001] The invention relates to a plastic corrugated pipe processing equipment, in particular to a plastic corrugated pipe forming machine. Background technique [0002] Plastic corrugated pipes are widely used in various municipal projects such as various pipe networks under roads and bridges. With the vigorous development of municipal projects, the demand for plastic corrugated pipes is increasing. At present, molding machines are generally used for the processing of plastic corrugated pipes, including motors, feeding devices, heating devices, extrusion devices, cooling devices, traction devices, cutting machines and other components. The forming module is parallel to the water pipe device with several small holes. By injecting water into the water pipe, the water is sprayed onto the forming module through the small holes for cooling. The cooling effect of this cooling method is very limited, and the cooling is uneven, resulting in different mechanical pro...

AI Technical Summary

Problems solved by technology

The cooling effect of this cooling method is very limited, and the cooling is uneven, resulting in different mechanical properties of the processed bellows and lower product quality.

At the same time, because the cooling speed is not enough, in order to increase the cooling effect, it is necessary to keep a longer forming module, which will cause a large part of the exit to be cooled and solidified, increasing the traction force to pull it out of the forming module. will damage the bellows
