Description

Technical Field

[0001] This utility model relates to the field of heat shrink tubing production technology, and in particular to a heat shrink tubing expansion machine. Background Technology

[0002] In existing technologies, heat shrink tubing is a specially designed polymer sleeve, typically made primarily of polyolefins (such as cross-linked polyethylene), with some products also incorporating an inner hot melt adhesive layer. Its core characteristic is that it shrinks radially after heating (e.g., with a heat gun), with a common shrinkage ratio of 2:1 to 4:1, ultimately adhering tightly to the surface of the target object. However, in existing technologies, the heat shrink tubing itself lacks control during expansion processing, making it prone to movement and thus affecting processing stability.

[0003] Therefore, this application proposes a heat shrink tubing expansion machine to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where heat shrink tubing lacks control and is prone to movement during expansion processing, thus affecting the stability of the process. Therefore, this invention proposes a heat shrink tubing expansion machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A heat shrink tubing expander includes a base;

[0007] A horizontal plate, which is fixedly connected to the top of the base;

[0008] A support plate, which is fixedly connected to the left side of the horizontal plate;

[0009] A control panel, which is slidably connected to the right side of the horizontal plate;

[0010] A positioning plate, which is fixedly connected to the left side of the control panel;

[0011] The control mechanism includes two movable plates, two pull plates, and an auxiliary plate. The movable plates are slidably connected to the top of the base, the pull plates are rotatably connected to the right side of the adjacent movable plates, the auxiliary plate is fixedly connected to the right side of the control plate, and the right side of the auxiliary plate is rotatably connected to the top of the two pull plates. A second spring is fixedly connected to the bottom of the auxiliary plate, and one end of the second spring is fixedly connected to the top of the base.

[0012] In a preferred embodiment of this utility model, a mating plate is slidably connected to the top of the base, and two contact wheels are rotatably connected to the top of the mating plate.

[0013] As a preferred embodiment of this utility model, the top of the base is slidably connected to two inclined panels. The inclined panels are fixedly connected to the right side of the adjacent movable plate. A No. 1 spring is fixedly connected to the side of the two inclined panels that are far apart from each other, and the side of the two No. 1 springs that are far apart from each other is fixedly connected to the top of the base. The inclined surface of the inclined panel is in active contact with the contact wheel.

[0014] As a preferred embodiment of this utility model, a second electric actuator is fixedly connected to the top of the base, and an expansion column is fixedly connected to one end of the second electric actuator.

[0015] As a preferred embodiment of this utility model, a first electric actuator is fixedly connected to the bottom of the base, and the output end of the first electric actuator is fixedly connected to the left side of the mating plate.

[0016] As a preferred embodiment of this utility model, the top of the support plate and the bottom of the positioning plate are both provided with arc-shaped grooves, and the inner walls of the two arc-shaped grooves are fixedly connected with rubber plates. Beneficial effects

[0017] 1. By placing the pipe in the arc groove of the support plate, the first electric actuator is controlled to work. The first electric actuator can pull the mating plate to move to the left. As the mating plate moves, the mating plate can synchronously control the contact wheel to move. At this time, the contact wheel can contact the inclined surface of the inclined plate, thereby controlling the two inclined plates to move away from each other.

[0018] 2. As the inclined plate moves, it can control the movement of the movable plate. When the movable plate moves, it can simultaneously pull the pull plate, which in turn pulls the auxiliary plate downwards. When the auxiliary plate moves, it can drive the control plate downwards. At the same time, as the control plate moves, it can drive the positioning plate downwards. At this time, the positioning plate cooperates with the support plate to fix the pipe. Meanwhile, the rubber plate inside the arc groove increases friction and ensures the stability of the fixation.

[0019] 3. The operation is carried out by controlling the No. 2 electric actuator. The No. 2 electric actuator can push the expansion column to the right, at which time the expansion column extends into the pipe to expand the pipe.

[0020] In this utility model: by placing the pipe in the arc-shaped groove of the support plate, the first electric actuator can control the positioning plate to descend, thereby fixing the pipe. At the same time, the rubber plate increases the friction and ensures the stability of the fixation. The second electric actuator can push the expansion column to move to the right, at which time the expansion column extends into the pipe to expand the pipe. Attached Figure Description

[0029] Support plate 15 is fixedly connected to the left side of horizontal plate 2;

[0030] Control panel 3 is slidably connected to the right side of horizontal plate 2;

[0031] Positioning plate 4 is fixedly connected to the left side of control plate 3;

[0032] The control mechanism includes two movable plates 9, two pull plates 10, and an auxiliary plate 11. The movable plates 9 are slidably connected to the top of the base 1.

A second spring 12 is fixedly connected to the bottom of the auxiliary plate 11, and one end of the second spring 12 is fixedly connected to the top of the base 1.

[0033] With the above structure, by setting up a support plate 15, which cooperates with the positioning plate 4, the pipe is fixed, ensuring stability and preventing movement.

[0034] As a preferred embodiment of this utility model, a mating plate 6 is slidably connected to the top of the base 1, and two contact wheels are rotatably connected to the top of the mating plate 6. When the mating plate 6 moves, the mating plate 6 can control the contact wheels to move synchronously.

[0035] As a preferred embodiment of this utility model, the top of the base 1 is slidably connected to two inclined plates 7. The inclined plates 7 are fixedly connected to the right side of the adjacent movable plate 9. A first spring 8 is fixedly connected to the side of the two inclined plates 7 that is far apart from each other, and the side of the two first springs 8 that is far apart from each other is fixedly connected to the top of the base 1. The inclined surface of the inclined plate 7 is in active contact with the contact wheel. When the contact wheel contacts the inclined surface of the inclined plate 7, the contact wheel can control the inclined plate 7 to move. At this time, the inclined plate 7 can synchronously control the movable plate 9 to move laterally.

[0036] As a preferred embodiment of this utility model, a second electric push rod 13 is fixedly connected to the top of the base 1, and an expansion column 14 is fixedly connected to one end of the second electric push rod 13. By setting the second electric push rod 13, the second electric push rod 13 can control the expansion column 14 to move laterally.

[0037] As a preferred embodiment of this utility model, a first electric actuator 5 is fixedly connected to the bottom of the base 1, and the output end of the first electric actuator 5 is fixedly connected to the left side of the mating plate 6. By setting the first electric actuator 5, the first electric actuator 5 can control the mating plate 6 to move left and right.

[0038] As a preferred embodiment of this utility model, the top of the support plate 15 and the bottom of the positioning plate 4 are both provided with arc-shaped grooves, and the inner walls of the two arc-shaped grooves are fixedly connected with rubber plates. By setting the arc-shaped grooves, the arc-shaped grooves can be easily adapted to the pipes, while the rubber plates ensure friction, thereby fixing the pipes.

[0039] It should be noted that the specific models of the No. 1 electric actuator 5 and the No. 2 electric actuator 13 used should be selected by those skilled in the art. Furthermore, the above information regarding the No. 1 electric actuator 5 and the No. 2 electric actuator 13 is existing technology and will not be elaborated upon in this solution.

[0040] The working principle of this utility model is as follows: In actual operation, the pipe is placed in the arc-shaped groove of the support plate 15. The first electric actuator 5 is then controlled to pull the mating plate 6 to the left. As the mating plate 6 moves, it simultaneously controls the contact wheel to move, allowing the contact wheel to contact the inclined surface of the inclined plate 7, thus controlling the two inclined plates 7 to move away from each other. Simultaneously, as the inclined plate 7 moves, it controls the moving plate 9 to move. When the moving plate 9 moves, it simultaneously pulls the pulling plate 10 to move as well. The auxiliary plate 11 is lowered by pulling the pull plate 10. When the auxiliary plate 11 moves, it can drive the control plate 3 to lower. At the same time, as the control plate 3 moves, it can drive the positioning plate 4 to lower. At this time, the positioning plate 4 cooperates with the support plate 15 to fix the pipe. At the same time, the rubber plate inside the arc groove increases the friction and ensures the stability of the fixation. Meanwhile, the second electric push rod 13 is operated by controlling the second electric push rod 13 to push the expansion column 14 to the right. At this time, the expansion column 14 extends into the pipe to expand the pipe.
