[0004] The applicant found that this patent had some shortcomings in use: when both ends of the plastic tube needed to be expanded, the device needed to rotate the screw to release the fixation of the plastic tube, then pull the plastic tube out of the rotating tube, change the direction of the plastic tube, and then insert it into the rotating tube to fix it, and then expand the other end of the plastic tube. The operation was cumbersome and affected the efficiency of expanding.

[0005] Therefore, the present invention designs a plastic pipe expansion device to solve the problems existing in the prior art. Utility Model Content

[0006] The purpose of the utility model is to provide a plastic pipe expansion device to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a plastic pipe expansion device, comprising: a base, a groove is opened on one side of the top of the base, a screw is rotatably installed in the groove, a slide is slidably installed on the outer wall of the screw, a servo motor is installed inside the upper part of the slide, the output end of the servo motor is connected to a turntable, a lower clamping seat and a gantry are installed on the top of the turntable, a screw is rotatably installed on the top of the gantry through a thread, the bottom of the screw is rotatably installed with the top of the upper clamping seat, a vertical plate is installed on the other side of the top of the base, a cone is installed on one side of the vertical plate, and a heating component is provided on one side of the cone.

The top of the main pipe is connected to a ring pipe, and the inner wall of the ring pipe is provided with a plurality of air nozzles. A hot air blower connected to the main pipe is installed on the vertical plate. When the hot air blower is started, the hot air enters the main pipe through the air outlet pipe of the hot air blower and then enters the ring pipe, and is finally ejected through the air nozzle to heat the surrounding area of ​​the pipe mouth and facilitate expansion.

[0009] Preferably, a plurality of rollers are provided at the bottom of the turntable and are in rolling connection with the slide. The rotation of the turntable drives the rollers to roll on the slide, thereby reducing the friction between the turntable and the slide.

[0010] Preferably, a guide rod slidably connected to the gantry is fixedly mounted on the top of the upper clamping seat, and the guide rod can improve the stability of the upper clamping seat when it is raised or lowered.

[0011] Preferably, the top of the lower clamping seat and the bottom of the upper clamping seat are both provided with rubber pads, which can protect the surface of the plastic pipe.

[0012] Preferably, a handle is installed on the top of the screw, which makes it convenient for workers to rotate the screw.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. In the utility model, after the expansion of one end of the pipe is completed, the screw drives the slide away from the cone, and then the servo motor drives the turntable to rotate 180 degrees, so that the plastic pipe rotates 180 degrees, and the other end of the plastic pipe is automatically turned to face the cone. There is no need to rotate the screw to release the fixation of the plastic pipe and then manually adjust the direction of the plastic pipe, which saves time and thus improves the efficiency of the expansion.
