[0052] A double-layer heating heat shrink tubing shrinking device includes a processing box 1, a first support plate 2, and a second support plate 3. The first support plate 2 is fixedly mounted on the processing box 1 and serves to support a lifting mechanism; the second support plate 3 is fixedly mounted on the processing box 1 and serves to support a heating mechanism; it also includes:

[0054] Reference Figure 3 and Figure 5 In a preferred embodiment, a moving mechanism is disposed on the processing box 1 to support the heat shrink tubing to be shrunk and to drive the heat shrink tubing to rotate; the moving mechanism includes:

[0055] Two fixing keys 7 are provided, and the two fixing keys 7 are symmetrically arranged on the processing box 1;

[0056] The first motor 8 is fixedly mounted on the fixed key 7;

[0057] A bidirectional lead screw 9 is rotatably mounted on the fixed key 7, and one end of the bidirectional lead screw 9 is fixedly connected to the output end of the first motor 8.

[0058] Two L-shaped moving plates 10 are provided, and the two L-shaped moving plates 10 are symmetrically arranged on the bidirectional lead screw 9. The L-shaped moving plates 10 are threadedly connected to the bidirectional lead screw 9.

[0059] During operation, the first motor 8 is started, which drives the bidirectional lead screw 9, which is fixedly connected to its output end, to rotate. The bidirectional lead screw 9 drives two L-shaped moving plates 10 to move towards each other along the moving groove 24. The L-shaped moving plates 10 are used to drive the supporting rotating mechanism to move towards each other, so that the supporting rotating mechanism can play a supporting role for heat shrink tubing of different diameters to be shrunk. The fixing key 7 is used to limit the position of the lead screw.

[0060] Reference Figure 5 In a preferred embodiment, two support rotation mechanisms are provided, symmetrically arranged on the L-shaped movable plate 10. The support rotation mechanism includes:

[0061] Two second motors 11 are provided, and the two second motors 11 are fixedly mounted on the L-shaped movable plate 10.

[0062] Two rotating rollers 12 are provided, and the two rotating rollers 12 are mounted on the second motor 11. One end of each rotating roller 12 is fixedly connected to the output end of the second motor 11.

[0063] Two T-shaped moving keys 13 are provided, and the two T-shaped moving keys 13 are symmetrically arranged on the processing box 1 and slidably connected to the processing box 1. The T-shaped moving keys 13 are rotatably connected to the rotating roller 12.

[0064] During operation, the L-shaped moving plate 10 drives two second motors 11 and the rotating roller 12 to move towards each other. The rotating roller 12 drives the T-shaped moving key 13 to move along the T-shaped sliding groove 25, thereby adjusting the position of the rotating roller 12 and supporting heat shrink tubing of different diameters. The second motor 11 is started, and the second motor 11 drives the rotating roller 12 to rotate, which causes the heat shrink tubing to rotate, thereby achieving uniform heating of the heat shrink tubing.

[0066] U-shaped fixing plate 14 is fixedly installed on the first support plate 2;

[0067] Hydraulic cylinder 15 is mounted on the first support plate 2 and is fixedly connected to the first support plate 2;

[0070] The lifting cover 18 is fixedly mounted on the limiting lifting rod 17.

[0071] During operation, the hydraulic cylinder 15 is activated, which drives the L-shaped lifting plate 16 to move up and down. The L-shaped lifting plate 16 is used to drive the fixed roller 4 to move up and down, and also to drive the limiting lifting rod 17 to move up and down. The limiting lifting rod 17 is used to drive the lifting cover 18 to move up and down, thereby reducing the gap between the lifting cover 18 and the processing box 1, thus reducing heat loss. The limiting lifting rod 17 is used to ensure the smooth up and down movement of the L-shaped lifting rod, dispersing the pressure on the single-sided load of the hydraulic cylinder 15, and effectively extending the service life of the hydraulic cylinder 15.

[0072] Reference Figures 2 to 4 In a preferred embodiment, the fixed roller 4 is disposed on the lifting mechanism;

[0073] There are two mounting slots 5, which are symmetrically arranged on the fixed roller 4.

[0074] The sleeve roller 6 is disposed on the fixed roller 4 and is slidably connected to the fixed roller 4;

[0075] During operation, rollers 6 of different diameters are manually moved along the mounting groove 5 to the fixed roller 4 to adjust the shrinkage diameter of the heat shrink tubing. The heat shrink tubing is manually placed on the roller 6, and the hydraulic cylinder 15 drives the fixed roller 4 to move up and down through the L-shaped lifting plate 16. The fixed roller 4 drives the heat shrink tubing to move up and down to the rotating roller 12 through the roller 6, and adjusts the position of the roller 6.

[0076] Reference Figure 1 and Figure 2 In a preferred embodiment, a heating mechanism is disposed on the processing box 1 and the second support plate 3, and is used to heat the heat shrink tubing to be shrunk. The heating mechanism includes:

[0077] The heating box 19 is fixedly mounted on the second support plate 3 and is fixedly connected to the processing box 1;

[0078] A uniformly dispersing plate 20 is fixedly mounted on the processing box 1;

[0079] A connecting pipe 21 is provided on the processing box 1 to connect the heating box 19 and the uniformly dispersing plate 20 to realize the delivery of hot air;

[0080] Heating component 22 is disposed inside the heating box 19 and is fixedly connected to the heating box 19;

[0081] Two hair dryers 23 are provided, and the two hair dryers 23 are symmetrically arranged on the heating box 19 and fixedly connected to the heating box 19.

[0082] During operation, the heating component 22 is activated to raise the temperature inside the heating chamber 19. The blower 23 is then activated, and the blower 23 delivers the high-temperature air inside the heating chamber 19 as hot air through the connecting pipe 21 to the uniformly dispersing plate 20. The uniformly dispersing plate 20 evenly disperses the hot air into the processing chamber 1, which heats and shrinks the inner and outer layers of the heat shrink tube, so that the heat shrink tube eventually forms a heat shrink tube with the same diameter as the sleeve roller 6, thereby achieving the effect of double-layer heating and shrinking.

[0083] The processing box 1 is provided with a circulation pipe 26, which is fixedly connected to the heating box 19 and is used to transport part of the hot air heated by the processing box 1 back into the heating box 19 to reduce energy loss.

[0084] Working principle: The first motor 8 is started, driving the bidirectional lead screw 9, which is fixedly connected to its output end, to rotate. The bidirectional lead screw 9 drives two L-shaped moving plates 10 to move towards each other. The L-shaped moving plates 10 drive two rotating rollers 12 to move towards each other. The rotating rollers 12 drive the T-shaped moving key 13 to move along the T-shaped moving groove 24 on the processing box 1, thus realizing the movement of the rotating rollers 12 and supporting heat shrink tubing of different diameters. The sleeve roller 6, with the same diameter as the heat shrink tubing to be shrunk, is manually moved along the mounting groove 5 onto the fixed roller 4, and the heat shrink tubing is placed on the sleeve roller 6. The hydraulic cylinder 15 is then started, driving the L-shaped lifting plate 16 downwards. The L-shaped lifting plate 16 drives the fixed roller 4 downwards, and the fixed roller 4 drives the sleeve roller 6 downwards. The sleeve roller 6 drives the heat shrink tubing downwards onto the rotating roller 12, and continues to descend to a suitable position. The second motor 11 is started, which drives the rotating roller 12 to rotate. The rotating roller 12 drives the heat shrink tubing to be shrunk to rotate. The heating component 22 is started, which heats the air in the heating box 19. The blower 23 is started, which delivers the hot air in the heating box 19 to the uniform dispersion plate 20 through the connecting pipe 21. The uniform dispersion plate 20 blows the hot air evenly into the processing box 1, uniformly heating the inner and outer layers of the rotating heat shrink tubing, thereby causing the heat shrink tubing to shrink onto the sleeve roller 6, realizing the processing of heat shrink tubing of different diameters. A portion of the hot air in the processing box 1 is transported back to the heating box 19 through the circulation pipe 26, thereby reducing energy loss.
