Two toothed teeth 36, two arc-shaped support plates 37 are symmetrically arranged inside the first through post 35, and a threaded rod 38 is arranged above one of the arc-shaped support plates 37. The outer side of each threaded rod 38 is threaded to the inside of the side end of the first through post 35. Multiple first teeth 34 mesh with multiple second teeth 36. Each support plate 33 is slidably connected to the side end of the moving block 7 near the side of the moving block 7. A first DC motor 5 is arranged on the right side of the worktable 1. A second bidirectional threaded rod 6 is arranged at the output shaft of the first DC motor 5. Each moving block 7 is threaded to the outer side of the second bidirectional threaded rod 6. A second DC motor 9 is arranged at the rear side of the heating box 2. A third bidirectional threaded rod 10 is arranged at the output shaft of the second DC motor 9.

[0017] The overall effect of Embodiment 1 is as follows: the relevant components can improve the heat uniformity of the heat shrink sleeve in the traditional plastic product heat shrink sleeve pressing device through mechanical transmission. By providing an arc-shaped groove on the outer side of the first through post 35 near the second through post 8, the first through post 35 can rotate stably inside the second through post 8. The function of the arc-shaped support plate 37 is to prevent the inner wall of the second through post 8 from rubbing against the outer wall of the steel pipe when the steel pipe rotates. This mechanical transmission method can improve the sealing, durability and safety of the connection parts.

[0018] Example 2, as Figures 1-5 As shown, the pressing mechanism 4 includes a first bidirectional threaded rod 41, a column 42 is provided on the rear side of the first bidirectional threaded rod 41, a synchronous belt 43 is provided at the output shaft of the second DC motor 9, two first plates 44 are symmetrically arranged on the outer side of the first bidirectional threaded rod 41 and the outer side of the third bidirectional threaded rod 10, and a second plate 46 is provided on the side of each pair of first plates 44 that are close to each other. An air bag 45 is provided on the side end of each first plate 44 and the side end of each second plate 46. The output shaft of the second DC motor 9 is connected to the column 42 through the synchronous belt 43.

[0019] The effect achieved by the entire embodiment 2 is as follows: by setting up the pressing mechanism 4, the output shaft of the second DC motor 9 rotates, and through the synchronous belt 43, the second bidirectional threaded rod 6 and the third bidirectional threaded rod 10 rotate. Every two first plates 44 promote the movement of the second plate 46. The airbag 45 presses the outer side of the steel pipe and the heat shrink sleeve. Through the rotation of the steel pipe and the heat shrink sleeve, full pressing is performed to prevent the ends of the heat shrink sleeve from curling up. The purpose of setting the airbag 45 to be made of fluororubber is that fluororubber is resistant to high temperature.

[0020] Inspect the mating surfaces of the two steel pipe sections to be connected to ensure they are flat. Place one steel pipe section between the two arc-shaped support plates 37 on the left side. Rotate the threaded rod 38, and the bottom of the upper arc-shaped support plate 37 presses against the outside of the steel pipe. Fit the heat shrink sleeve onto the right side of the steel pipe. Repeat the above operation to install the other steel pipe section between the two arc-shaped support plates 37 on the right side. The right-side steel pipe is closer to the center of the workbench 1. After installation, turn on the heating box 2. After preheating, start the first DC motor 5. The output shaft of the first DC motor 5 drives the second bidirectional threaded rod 6 to rotate, promoting the two steel pipes to be inside the heating box 2. At the same time, curtains are set on the left and right sides of the heating box 2 to maintain the temperature inside the heating box 2. When the two steel pipes are close together and in contact, start the second DC motor 9. The output of the second DC motor 9... The output shaft drives the column 42 to rotate via the synchronous belt 43, causing the first bidirectional threaded rod 41 and the third bidirectional threaded rod 10 to rotate. The first plate 44 and the second plate 46 on the front and rear sides are pushed towards the steel pipe. The airbag 45 presses against the outside of the heat shrink sleeve. The output shaft of the second DC motor 9 flips, and the airbag 45 moves away from the steel pipe. The electric telescopic rod 31 is started synchronously. The extended end of the electric telescopic rod 31, through the connecting plate 32, promotes the engagement of the first tooth 34 and the second tooth 36 on the upper side of the support plate 33. The first through column 35 rotates inside the second through column 8. After changing direction, the second DC motor 9 is started again. The airbag 45 adheres to the outside of the heat shrink sleeve and presses it. After pressing is completed, the second DC motor 9 reverses, the airbag 45 moves away from the outside of the heat shrink sleeve, the heating box 2 is closed, and the heat shrink sleeve is allowed to cool naturally.
