Description

Technical Field

[0001] The utility model relates to the technical field of PE plastic pipes, in particular to a PE plastic pipe hot-drawing device with adjustable positioning. Background Art

[0002] PE plastic pipes are made of synthetic resin, stabilizers, lubricants, etc., and are extruded through a pipe making machine. Due to the large diameter of some PE plastic pipes, a heat-stretching device is usually used to heat, soften, and stretch the PE plastic pipes for easy processing. However, the existing device still has some defects; for example;

[0003] For example, a plastic pipe hot pulling device with the publication number CN219466993U, when using the technology, the pipe body is inserted into the interior of the two clamping frames through one end of the device, and the adjusting screw is rotated. The adjusting screw drives the extrusion plate to clamp and fix the two ends of the pipe body. At this time, the pipe body is arranged inside the rotating tube. The rotating tube is rotated to align the side holes with the electric heating rods on both sides. The electric heating rods heat the pipe body through the side holes. The heat generated by the electric heating rods can also enter the interior of the rotating tube, which is convenient for all-round heating of the pipe body. There is no need to rotate the pipe body to prevent the pipe body from being twisted due to rotation. After the heating is completed, the servo motor is started. The servo motor can adjust the clamping mechanism on one side through the stretching screw, sliding rod and fixed plate, which is convenient for stretching the heated pipe body.

[0004] There are some problems with the above device. The device is cumbersome to use and has a low degree of automation. In addition, the device is stretched by stretching the screw and the slide rod. When the slide rod is extended too long, it becomes unstable and may be damaged, resulting in poor performance.

At this time, start the heater 16 in the rotating tube 11 to heat the PE plastic tube, and at the same time start the second motor 12 to drive the rotating rod 13 to rotate, so that the first The gear 14 rotates, and due to the meshing of the first gear 14 and the second gear 15, the second gear 15 drives the rotating tube 11 to rotate inside the body 1, causing the heater 16 inside the rotating tube 11 to rotate. The heat generated by the heater 16 heats the PE plastic tube through the filter holes on the surface of the rotating tube 11, which can better heat the PE plastic tube in all directions. At this time, the first motor 8 is started to drive the screw rod 9 to rotate, so that the slider 10 above the screw rod 9 moves in the slide groove inside the body 1.
