[0041] When the present application is used, first, the base 1 is placed in the plastic-lined composite pipe pipe penetrating area. Then, the plastic pipe is conveyed to the right through the second mounting frame 21 by the external pipe conveying device. The steel pipe is conveyed to the conveying assembly 31. The position of the steel pipe is adjusted by the conveying assembly 31 so that the steel pipe is above the positioning assembly 4. Then, the steel pipe is moved upward by the positioning assembly 4. The steel pipe is aligned with the plastic pipe.

[0042] After alignment, the processor starts the first electric sliding rail 51 by the control module. The guide rod 52 is pushed to move leftwards so that the guide rod 52 and the first support frame 53 pass through the steel pipe. The conical arc plate 54 is pushed into the plastic pipe. Then, the heating module 84 is started.

Then, the fourth electric sliding rail 82 is started. The support block 83, the hot pressing outer rod 86 and the heat conduction rod 87 are moved downward to contact with the plastic pipe port. Then, the circular electric sliding rail 81 is started. The fourth electric sliding rail 82, the support block 83, the hot pressing outer rod 86 and the heat conduction rod 87 rotate around the plastic pipe for one circle. The plastic pipe is heated and softened. The plastic pipe port is deformed to be attached to the conical arc plate 54. The cooling module 57 is used to cool and shape the plastic pipe after deformation. Then, the air cylinder 55 is started. The conical clamp cylinder 56 is pushed to move leftwards to clamp the plastic pipe with the conical arc plate 54. Then, the first electric sliding rail 51 is started. The guide rod 52 is moved rightwards to pull the plastic pipe to move rightwards and penetrate into the steel pipe. Thus, the plastic pipe can be automatically fixed for pipe penetrating operation. The labor is saved. The pipe penetrating efficiency and quality are improved.

[0043] When the pipe is penetrated, the processor starts the second electric sliding rail 501 by the control module. The wedge-shaped support frame 502 is moved leftwards.

Before pipe penetrating operation, the air bag 102 is in the steel pipe. The air pump is started. The air bag 102 is inflated. When the pipe is penetrated, the cleaning brush 103 moves along the inner wall of the steel pipe to clean the inner wall of the steel pipe. Thus, the inner wall of the steel pipe can be cleaned while the pipe is penetrated. The operation process is simplified. The operation efficiency is improved.

[0045] As shown in the figures, Figure 8 and Figure 9As shown, it also includes a slitting mechanism 6, which includes a second support frame 61, an electric push rod 62 and a beveling cutter 63, the left side of the first support frame 53 is connected with the second support frame 61, three electric push rods 62 are connected to the second support frame 61, the electric push rod 62 and the processor are electrically connected through the control module, the extension end of the electric push rod 62 is connected with the beveling cutter 63, and the beveling cutter 63 is inclined inward to facilitate slitting the plastic pipe.

[0046] Using the slitting mechanism 6 of the device, the deformed part of the plastic pipe can be slitted. After the plastic pipe is inserted, the processor starts the electric push rod 62 on the second support frame 61 through the control module to push the beveling cutter 63 to move outward to slit the deformed part of the plastic pipe, and then the conical arc plate 54 continues to move to the right to facilitate the conical arc plate 54 to separate from the plastic pipe, facilitating subsequent operation.

[0047] As shown in Figure 1 and Figure 2 It also includes a cutting pipe mechanism 7, which includes a third electric sliding rail 71, a motor 72 and a saw blade 73, the upper left side of the first mounting frame 2 is connected with the third electric sliding rail 71, the third electric sliding rail 71 and the processor are electrically connected through the control module, the sliding block of the third electric sliding rail 71 is connected with the motor 72, the motor 72 and the processor are electrically connected through the control module, and the output shaft of the motor 72 is connected with the saw blade 73.

[0048] Using the cutting pipe mechanism 7 of the device, the deformed part of the plastic pipe can be cut. After the conical arc plate 54 separates from the plastic pipe, the processor starts the third electric sliding rail 71 and the motor 72 through the control module to move the saw blade 73 to the deformed part of the plastic pipe to cut it off, thereby completing the pipe insertion operation of the plastic-lined composite pipe, and then the inserted steel pipe is conveyed to the next working area by the conveying assembly 31.

[0049] As shown in Figure 1 and Figure 10 It also includes a spraying mechanism 9, which includes a storage tank 91, a delivery pipe 92, an electric pump 93, a spray pipe 94, a high-temperature-resistant rubber plate 95, a spray plate 96 and a mounting seat 97, the middle upper side of the connecting frame 841 is connected with the storage tank 91, the right side of the storage tank 91 is connected with the delivery pipe 92, the lower side of the delivery pipe 92 is connected with three electric pumps 93, the electric pump 93 and the processor are electrically connected through the control module, the lower side of the electric pump 93 is connected with the spray pipe 94, the lower side of the connecting frame 841 is connected with three mounting seats 97, the electric pump 93 is connected with the adjacent mounting seat 97, the lower side of the mounting seat 97 is connected with the high-temperature-resistant rubber plate 95, the inner side of the high-temperature-resistant rubber plate 95 is connected with the spray plate 96, and the spray plate 96 is connected with the adjacent spray pipe 94.

[0050] The spraying mechanism 9 of the device can prevent the hot pressing outer rod 86 from adhering to the plastic pipe. When the hot pressing outer rod 86 moves downward, the processor starts the electric pump 93 through the control module, and the release agent in the storage tank 91 is transported to the spray plate 96 through the conveying pipe 92 and the spray pipe 94, so that the spray plate 96 sprays the release agent on the hot pressing outer rod 86. The high-temperature-resistant rubber plate 95 can limit the spraying range of the release agent. When the hot pressing outer rod 86 passes through the high-temperature-resistant rubber plate 95, the high-temperature-resistant rubber plate 95 can evenly wipe the release agent on the hot pressing outer rod 86, thereby preventing the hot pressing outer rod 86 from adhering to the plastic pipe due to high temperature.
