[0004] In the above technical solution, fixing blocks of different diameters are used to fix and limit the plastic pipe that needs to be sealed. However, since the above technical solution completes the fixing operation by plugging the fixing block into the plastic pipe, the fixing block fits the plastic pipe, which will cause friction damage to the wall of the plastic pipe. The gap between the fixing block and the plastic pipe is large, which will cause the plastic pipe to tilt during processing. Utility Model Content

[0005] The utility model aims to solve the problems in the prior art that the fixing block fits the plastic pipe, causing friction damage to the pipe wall of the plastic pipe, and the gap between the fixing block and the plastic pipe is large, which causes the plastic pipe to tilt during processing, and proposes a plastic pipe sealing machine.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A plastic pipe sealing machine, comprising a machine body, a mounting groove is provided on the machine body, a motor is fixedly installed in the mounting groove, a rotating shaft is fixedly connected to the output end of the motor, a placement seat is fixedly connected to the rotating shaft, a mounting plate is integrally connected to the placement seat, a guide rod is slidably sleeved on the mounting plate, a first clamping piece for fixing and clamping the outer wall of the plastic pipe is fixedly connected to the guide rod, a spring is welded between the first clamping piece and the mounting plate, and a second clamping piece for fixing and clamping the inner wall of the plastic pipe is slidably sleeved on the placement seat;

[0008] The placement seat is provided with a driving assembly for driving the second clamping member to move inward.

[0009] Preferably, a guide ring groove is provided on the machine body, and a guide sliding block fixedly connected to the placement seat is slidably sleeved in the guide ring groove.

[0010] Preferably, the mounting plate is provided with a movable through hole for slidingly fitting the guide rod, and the spring is movably fitted on the guide rod.

[0011] Preferably, a limiting groove for slidingly fitting the second clamping member is provided on the placement seat, the first clamping member and the second clamping member are arc-shaped structures arranged corresponding to the plastic pipe, and the contact surface between the first clamping member and the plastic pipe and the contact surface between the second clamping member and the plastic pipe are both fixedly provided with rubber pads.

[0012] Preferably, the driving assembly comprises a driving cavity opened in the placement seat, a driving rod is slidably sleeved in the driving cavity, and a traction rod is connected between the driving rod and the second clamping member.

[0013] Preferably, a guide through hole for slidingly fitting the driving rod is provided on the placement seat, and both ends of the traction rod are pin-connected to the driving rod and the second clamping member respectively.

[0014] Compared with the prior art, the utility model has the following advantages:

[0015] Compared with the prior art, the utility model replaces the fixing blocks of different diameters and fixes and limits the plastic pipe by the fixing blocks. However, since the fixing blocks will cause friction damage to the wall of the plastic pipe when they are in contact with the plastic pipe, the stability of the plastic pipe cannot be guaranteed when the fixing blocks are not in contact with the plastic pipe. In the technical solution, the first clamping member and the second clamping member that are movably arranged can fix and clamp the inner and outer walls of the plastic pipe at the same time, which helps to ensure the stability of the plastic pipe during the sealing operation, and the first clamping member and the second clamping member can be kept away from the plastic pipe through the guide rod and the driving rod, so as to avoid friction when the plastic pipe is disassembled.
