[0042] The working process of the plastic pipe splicing equipment of the utility model is as follows: open the upper box body 1, press the opening and closing button, and start the controller. Press the lifting button to adjust the height of the lifting frame 52 according to the size of the splicing mold 72. According to the size of the splicing mold 72, adjust the position of the lifting slide 54 on the lifting column 53, put the splicing mold 72 on the first top block 55 on the lifting frame 52, and make the second top block 56 abut against the splicing mold 72. Limit the pipe parts 71 to be spliced ​​on both sides between the two relatively set limiting monomers 8, and make one end of the pipe part 71 to be spliced ​​abut against the splicing mold 72. Press the support button, the support motor 43 starts, drives the swing arm 42 to rotate, and the swing arm 42 pulls the lower sliding rod 41 to rise, thereby pushing the first column 44 and the second column 45 to slide upward, and continue to rise until the support wheel 48 and the push block 461 are both against the pipe part 71 to be spliced.

[0043] The controller automatically controls the lifting driver 51 on the upper side to be in contact with the splicing mold 72, and turns on the electric heating element, which conducts heat energy to the splicing mold 72 through the first top block 55. After the temperature of the splicing mold 72 rises to a temperature that can reshape the pipe part 71 to be spliced, the heating component is turned off and the propulsion motor 462 is started. The propulsion arm 464 rotates to drive the push rod 465 and the push block 461 to move. Due to the setting of the propulsion spring 466, the push block 461 is always tightly against the pipe part 71 to be spliced. During the movement of the push block 461, the friction force pushes the pipe part 71 to be spliced ​​toward the splicing mold 72. Under the action of the heated splicing mold 72, the pipe part 71 to be spliced ​​is melted and reshaped into a shape that matches the shape of the splicing mold 72. The two sides of the splicing mold 72 are in a shape that can be spliced ​​together.

[0044] After the pipe fitting 71 to be spliced ​​stays in the splicing mold 72 for a period of time, the shaping is completed, and the propulsion motor 462 is started again to rotate in the opposite direction to pull the pipe fitting 71 to be spliced ​​away from the splicing mold 72. The lifting drive 51 is started to lower the splicing mold 72 on the lifting frame 52 to a position close to the bottom of the lower operating slot 22. The propulsion motor 462 is started to push the pipe fittings 71 to be spliced ​​on both sides inward, so that one pipe fitting is inserted into another pipe fitting to complete the splicing. The controller is also provided with a buzzer. After the splicing is completed, the buzzer sounds to remind the operator that the splicing is completed. The operator can open the upper box 1 to take out the spliced ​​plastic pipe for use.

[0045] In this specification, each embodiment is described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referred to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part.
