Embodiment 1

[0033] First, the equipment is preheated for more than 3 hours, after the temperature reaches the set value. Start mixing, mix according to the ratio of 100 parts of HDPE resin, 3 parts of color masterbatch, and 15 parts of short-wave fiber masterbatch, and the mixing time is 5 minutes. The material is sucked into the hopper of the extruder by the vacuum suction machine. After the extruder is turned on, the servo motor (5) is turned on to make the heating plate (9) close to the mold drum (3). After heating to 100°C, winding is carried out, first winding the socket position, then winding the straight section, and finally winding the forming socket. Hoist the mold drum (3) onto the turning table by driving, and cut the socket and socket positions at the same time. After reaching a certain size requirement, use the cooling fan (2) for air cooling. After the pipe is cooled to 60°C, hoist the drum to the The demoulding machine is used for demoulding. After the completion, the sock...

Embodiment 2

[0035] First, the equipment is preheated for more than 3 hours, after the temperature reaches the set value. Start mixing, mix according to the ratio of 100 parts of HDPE resin, 3 parts of color masterbatch, and 20 parts of short-wave fiber masterbatch, and the mixing time is 5 minutes. The material is sucked into the hopper of the extruder by the vacuum suction machine. After the extruder is turned on, the servo motor (5) is turned on to make the heating plate (9) close to the mold drum (3). After heating to 130°C, winding is carried out. First, the position of the socket is wound, then the straight section is wound, and finally the socket is formed. Hoist the mold drum (3) onto the turning table by driving, and cut the socket and socket positions at the same time. After reaching a certain size requirement, use the cooling fan (2) for air cooling. After the pipe is cooled to 60°C, hoist the drum to the The demoulding machine is used for demoulding. After the completion, the ...

Embodiment 3

[0037] First, the equipment is preheated for more than 3 hours, after the temperature reaches the set value. Start mixing, mix according to the ratio of 100 parts of HDPE resin, 3 parts of color masterbatch, and 30 parts of short-wave fiber masterbatch, and the mixing time is 5 minutes. The material is sucked into the hopper of the extruder by the vacuum suction machine. After the extruder is turned on, the servo motor (5) is turned on to make the heating plate (9) close to the mold drum (3). After heating to 150°C, winding is carried out. First, the position of the socket is wound, then the straight section is wound, and finally the socket is formed. Hoist the mold drum (3) onto the turning table by driving, and cut the socket and socket positions at the same time. After reaching a certain size requirement, use the cooling fan (2) for air cooling. After the pipe is cooled to 60°C, hoist the drum to the The demoulding machine is used for demoulding.

Abstract

The invention discloses production equipment and a production technology for an HDPE (high density polyethylene) spirally enwound structure-wall pipe (Krah pipe).The equipment comprises a base trolley, cooling fans, a mold roller, rolling wheels, a servo motor, an infrared heating device and a rotating rod. The technology comprises material mixing, feeding, vacuum feeding, extrusion, enwinding, turning, demolding, modification, electric fuse distribution, inspection and storage. According to the production equipment and the production technology, infrared high-frequency heating is adopted, the heating efficiency is high, the cost is low, and the operation is simple and convenient; the ring stiffness is increased by above 30% due to addition of short-glass-fiber master batches; characteristics of HDPE are adopted, so that the comprehensive performance of the pipe is improved; the weld seam quality of the pipe is guaranteed, and the weld seam quality and the overall external pressure resistance of the pipe are also improved.

Description

technical field [0001] The invention relates to the technical field of plastic pipes, in particular to a production process for a high-density polyethylene winding wall carat pipe. Background technique [0002] Large-diameter reinforced composite winding structure wall pipe is a new type of pipe made of high-density polyethylene and modified polypropylene as the main raw materials through the complete set of carat pipe production equipment.
