[0030] Embodiment

[0031] Such as Figure 1 And Figure 2As shown in the figure, the hot melt butt welding machine for PTFE single - cavity pipes proposed by the utility model includes a bottom plate 1, and also includes a frame 2 fixedly installed on the top of the bottom plate 1. The frame 2 is in a rectangular - shaped loop, composed of four symmetric support rods and a rectangular frame. A rectangular groove 3 is opened at the top of the bottom plate 1 below the frame 2, and a moving block 4 is slidably installed in the rectangular groove 3;

[0032] In addition, two moving blocks 4 are installed. A fixing frame 5 is fixedly installed on the moving block 4. A rectangular installation frame 6 is connected to the top of the fixing frame 5. A reinforcing block is provided at the connection between the fixing frame 5 and the rectangular installation frame 6 to make the installation of the rectangular installation frame 6 more firm and stable. A pipe - placing rack 7 is arranged in the rectangular installation frame 6, and the two pipes to be connected are placed on the pipe - placing rack 7;

[0033] It should be noted that guide grooves 17 are opened on both sides of the top of the frame 2, and sliders 15 are slidably installed in the guide grooves 17. The top of the two sliders 15 is fixedly connected to a connecting plate 16. A support plate 14 fixedly connected to the rectangular installation frame 6 is fixedly installed at the bottom of the connecting plate 16. By connecting the connecting plate 16 and the rectangular installation frame 6 through the support plate 14, and cooperating with the sliders 15 and the guide grooves 17, it is more conducive to the movement of the moving block 4;

A driving motor 34 is fixedly installed on one side of the bottom plate 1, and the output shaft of the driving motor 34 is fixedly connected to the threaded rod 33. Opposite internal threads are provided between the two moving blocks 4 and the threaded rod 33, so that the two moving blocks 4 can move towards each other;

[0035] Even further, when the driving motor 34 is started to make the threaded rod 33 rotate, under the guidance of the guide grooves 17, the sliders 15 cooperate with the moving blocks 4 to make the pipes placed on the two pipe - placing racks 7 move closer to each other, facilitating subsequent hot melt connection.

[0036] As Figure 2 and Figure 3 shown, the device also includes an adjusting device. The adjusting device is arranged on the rectangular installation frame 6 for adjusting the rotation of the single - cavity pipes placed on the pipe - placing rack 7. The adjusting device includes a rotating shaft 9 rotatably installed on one side of the rectangular installation frame 6. One end of the rotating shaft 9 located inside the rectangular installation frame 6 is connected to a fixing disk 8, and the fixing disk 8 is fixedly connected to the pipe - placing rack 7. A motor 10 is fixedly installed on the other side of the rectangular installation frame 6, and the output shaft of the motor 10 is fixedly connected to the rotating shaft 9. When the motor 10 is started, the rotating shaft 9 can drive the fixing disk 8 to rotate, so that the two pipes placed in the pipe - placing rack 7 can be respectively adjusted to rotate, facilitating better butt - joint connection;

[0037] It should be noted that a fixing device is provided on the placement pipe rack 7. The fixing device includes a top plate 11 fixedly installed on the outer wall of the top of the placement pipe rack 7. An electric push rod 12 is fixedly installed at the bottom of the top plate 11. The bottom end of the electric push rod 12 is connected with a fixing member 13. The fixing member 13 is arc-shaped corresponding to the shape of the pipeline. The electric push rod 12 is used to drive the fixing member 13 to move downward to fixedly clamp the pipeline, so that the pipeline is fixed on the placement pipe rack.

[0038] As Figures 2 - 4 shown, the device further includes a cleaning component. The cleaning component is connected to the U-shaped mounting frame 6 for cleaning and brushing the end of the pipeline. The cleaning component includes a sliding plate 19 slidably installed on the support plate 14. An electric telescopic rod 20 is fixedly installed at the bottom of the sliding plate 19. The position of the electric telescopic rod 20 is located at the top end of the sliding plate 19 near the end of the pipeline. An installation plate 21 is connected to the electric telescopic rod 20. An adjustment rod 22 is rotatably installed on the installation plate 21. The bottom end of the adjustment rod 22 is connected with a vertical plate 23. The adjustment rod 22 is in the form of an electric rotating rod, and the rotation of the adjustment rod 22 can be used to drive the adjustment rotation of the vertical plate 23;

[0039] Furthermore, a rotating rod 25 is rotatably installed on one side of the vertical plate 23. A rotating plate 26 is arranged on the rotating rod 25. A cleaning sponge 27 is fixedly connected to the rotating plate 26. A micro motor 24 is fixedly installed on the other side of the vertical plate 23. The output shaft of the micro motor 24 is fixedly connected to the rotating rod 25. The micro motor 24 is started to make the rotating rod 25 rotate, so that the rotating plate 26 rotates to drive the cleaning sponge 27 to rotate, which can contact and friction clean the end of the pipeline;

[0040] Even further, a spraying device is arranged on one side of the support plate 14. The spraying device includes a liquid storage tank 28 fixedly installed on one side of the support plate 14 below the sliding plate 19. The liquid storage tank 28 is connected with a water guide pipe 29 through a water pump. The water guide pipe 29 is composed of a plurality of telescopic hoses, which can provide sufficient length to support the movement of the water guide pipe 29 as the sliding plate 19 slides. A nozzle 30 is arranged at the top end of the water guide pipe 29, and the nozzle 30 can evenly spray the cleaning liquid in the liquid storage tank 28;

[0041] Even further, a notch 18 for the sliding plate 19 to slide is formed on the support plate 14. A connecting frame 31 is fixedly installed on the side of the sliding plate 19 away from the electric telescopic rod 20. A pull rod 32 is connected to the connecting frame 31, and the pull rod 32 can be pulled to slide the sliding plate 19 back and forth for adjustment, and accurate adjustment can be made according to the length of the pipeline and the distance from the end.

[0042] Working principle: Before connecting two single-chamber pipes, by the length of the pipe on the placement pipe rack 7, pull the pull rod 32 to slide the sliding plate 19 back and forth for adjustment, so that the sliding plate 19 can move to an appropriate distance from the end of the pipe. Then, use the extension of the electric telescopic rod 20 to drive the vertical plate 23 to move downward, so that the cleaning sponge 27 can just be located at the connecting end of the pipe. Start the micro motor 24, which can make the rotating rod 25 rotate, so that the rotating plate 26 drives the cleaning sponge 27 to rotate, and adjust the sliding plate 19 so that the cleaning sponge 27 can be in frictional contact with the connecting end of the pipe. At the same time, use the water pump to export the cleaning liquid in the liquid storage tank 28 from the water guide pipe 29 and finally evenly spray it on the pipe end and the cleaning sponge 27 by the nozzle 30, so that impurities such as oil stains and pollutants at the pipe end can be cleaned. It is also possible to use the push of the electric push rod 12 to drive the fixing member 13 to fixedly clamp the pipe on the placement pipe rack 7. Start the motor 10, so that the rotating shaft 9 drives the fixed disk 8 to rotate, so that the placement pipe rack 7 rotates, and the end of the pipe also generates relative rotational friction with the cleaning sponge 27, which can make the cleaning effect better.

[0043] The above specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
