[0002] In the existing technology, heat shrink tubing is a specially made heat shrink sleeve made of polyolefin material. The outer layer is made of high-quality, soft cross-linked polyolefin material and the inner layer is made of hot melt adhesive. The outer layer material has the characteristics of insulation, corrosion resistance and wear resistance, while the inner layer has the advantages of low melting point, waterproof sealing and high adhesion. In the existing technology, the heat shrink tubing lacks control during expansion, which can easily lead to deviations and affect the expansion.

[0003] Therefore, this application proposes an expansion molding device for heat shrink tubing to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where the expansion of heat shrink tubing lacks control, which can easily lead to deviations and affect the expansion process. Therefore, this invention proposes an expansion and forming device for heat shrink tubing.

The horizontal plate is slidably connected to the front side of the base, the motor is fixedly connected to the top of the horizontal plate, the gear is fixedly connected to the front end of the motor output shaft, and the rack is fixedly connected to the front side of the control frame.

[0012] As a preferred embodiment of this utility model, an expansion column is fixedly connected inside the control frame, and a second spring is fixedly connected to the right side of the control frame, with one end of the second spring fixedly connected to the top of the base.

[0013] In a preferred embodiment of this utility model, an electric push rod is fixedly connected to the front side of the support plate, and a drive plate is fixedly connected to the output shaft of the electric push rod. A pull plate is rotatably connected to the front side of the drive plate, and the top of the pull plate is rotatably connected to the front side of the sliding plate. A first spring is fixedly connected to the bottom of the sliding plate, and one end of the first spring is fixedly connected to the top of the support plate.

[0017] 1. By placing the heat shrink tubing material on the support base, the electric actuator is controlled to move the drive plate to the right. When the drive plate moves, it pulls the pull plate, which in turn pulls the sliding plate downwards. As the sliding plate moves, it controls the positioning plate to descend. The descending positioning plate then cooperates with the support base to fix the heat shrink tubing material, thus ensuring the stability of the material.

[0018] 2. As the drive plate moves, it can pull the connecting plate to move. At this time, the movement of the connecting plate can pull the horizontal plate to rise. The movement of the horizontal plate can guide the gear and rack to mesh.

[0019] 3. Control the motor to work. The motor controls the rack to move through the gears. At this time, the movement of the rack can synchronously drive the control frame to move. As the control frame moves, the control frame guides the expansion column to contact the heat shrink tubing material, so as to achieve the effect of automatic expansion.

[0020] In this invention: by placing the heat shrink tubing material on the support base, the positioning plate can be lowered by controlling the operation of the electric push rod. At this time, the lowering of the positioning plate can cooperate with the support base to fix the heat shrink tubing material, thereby ensuring the stability of the material. In addition, the operation of the motor can assist the control frame in guiding the expansion column to contact the heat shrink tubing material, so as to achieve the effect of automatic expansion.

[0034] As a preferred embodiment of this utility model, an expansion column 17 is fixedly connected inside the control frame 14, and a second spring 15 is fixedly connected to the right side of the control frame 14. One end of the second spring 15 is fixedly connected to the top of the base 1. When the control frame 14 moves, the control frame 14 assists the expansion column 17 in moving. By setting the second spring 15, the second spring 15 has the effect of pulling the control frame 14 back to its original position.

[0035] In a preferred embodiment of this utility model, an electric push rod 3 is fixedly connected to the front side of the support plate 2, and a driving plate 4 is fixedly connected to the output shaft of the electric push rod 3. A pull plate 5 is rotatably connected to the front side of the driving plate 4. The top of the pull plate 5 is rotatably connected to the front side of the sliding plate 6. A first spring 7 is fixedly connected to the bottom of the sliding plate 6, and one end of the first spring 7 is fixedly connected to the top of the support plate 2. By setting the electric push rod 3, the electric push rod 3 controls the driving plate 4 to move laterally.

By setting the first spring 7, the first spring 7 plays the role of assisting the sliding plate 6 to rise and return to its original position.

[0036] As a preferred embodiment of this utility model, a connecting plate 10 is rotatably connected to the front side of the driving plate 4, and the bottom of the connecting plate 10 is rotatably connected to the front side of the horizontal plate 11. When the driving plate 4 moves, the driving plate 4 pulls the connecting plate 10 to move, and at this time the horizontal plate 11 can be pulled up simultaneously.

[0037] As a preferred embodiment of this utility model, the top of the base 1 is provided with a sliding groove, and the bottom of the control frame 14 is slidably connected to the inner wall of the sliding groove.

[0040] The working principle of this utility model is as follows: In actual operation, the heat shrink tubing material is placed on the support base 8. The electric actuator 3 is then controlled to move the driving plate 4 to the right. As the driving plate 4 moves, it pulls the pull plate 5, which in turn pulls the sliding plate 6 downwards. With the movement of the sliding plate 6, the positioning plate 9 is lowered. This lowered positioning plate 9 engages with the support base 8 to fix the heat shrink tubing material, thus ensuring its stability. Qualitatively, as the driving plate 4 moves, it can pull the connecting plate 10 to move. At this time, the movement of the connecting plate 10 can pull the horizontal plate 11 to rise. The movement of the horizontal plate 11 can guide the gear 13 to mesh with the rack 16. At this time, the control motor 12 works and controls the rack 16 to move through the gear 13. The movement of the rack 16 can synchronously drive the control frame 14 to move. As the control frame 14 moves, it guides the expansion column 17 to contact the heat shrink tubing material, achieving the effect of automatic expansion.
