Description

Technical Field

[0001] The utility model relates to the technical field of wire harness heat shrinkers, and particularly relates to an auxiliary mechanism for a wire harness heat shrinker. Background Technique

[0002] A heat shrinker, also known as a heat shrinkage machine or shrink packaging machine, operates on the principle that when the heat shrinkable film is heated, the irregular arrangement of the original molecules changes. Under thermal radiation such as infrared rays, the plastic molecules are rearranged closely, thereby greatly reducing the original area and tightly adhering to the product surface to achieve the packaging purpose and improve the durability of the article. It is widely used in various fields, such as the wire harness production industry. After the wire harness production is completed, in order to achieve the insulation, sealing and protection effects of the wire harness, a wire harness heat shrinker is used to apply heat shrinkage to the wire harness.

[0003] A wire harness heat shrinker with the patent number CN218241433U is provided with a positioning tooling for the wire harness and a heat shrinkage tooling that feeds along the radial direction of the wire harness. The wire harness tooling includes two wire harness fixing blocks, and wire harness positioning grooves for positioning the wire harness are provided at corresponding positions of the wire harness fixing blocks. By moving the heat shrinkage tooling instead of the positioning tooling, the positioning requirements for the wire harness are reduced, and the versatility is stronger.

[0004] However, research shows that the existing wire harness heat shrinkers still have the following defects:

[0005] When using the existing wire harness heat shrinkers, generally both hands are needed to hold both ends of the wire harness to perform heat shrinkage, and the wire harness needs to be taken out of the wire harness heat shrinker after the heat shrinkage is completed. Only after one wire harness is heat shrunk can the next wire harness be prepared, which is time-consuming. Therefore, through technological innovation and design optimization, it is necessary to optimize an auxiliary mechanism for a wire harness heat shrinker. Content of the Utility Model

[0006] When using the existing wire harness heat shrinkers, generally both hands are needed to hold both ends of the wire harness to perform heat shrinkage, and the wire harness needs to be taken out of the wire harness heat shrinker after the heat shrinkage is completed. Only after one wire harness is heat shrunk can the next wire harness be prepared, which is time-consuming. To solve the above problems, the embodiment of the present application provides an auxiliary mechanism for a wire harness heat shrinker. By setting a driving part to drive a pushing part to push out the wire harness inside the U-shaped block, there is no need for the staff to manually remove it, which improves the work efficiency. At the same time, by setting a limiting block and a spring, the wire harness can be limited to prevent the wire harness from slipping out of the U-shaped block during heat shrinkage.

[0007] The technical solution adopted by the embodiment of the present application to solve its technical problems is:

[0008] An auxiliary mechanism for a wire harness heat shrinker includes:

[0009] The heat shrinker body;

[0011] In a possible implementation manner, the pushing part includes a movable moving plate located on one side of the U-shaped block. A guide rod that can slide on a fixed block is fixed on the moving plate. A fixed block is fixed on the side of the heat shrinker body. The guide rod penetrates through the fixed block and can slide on the fixed block. At the same time, the guide rod will drive the moving plate to move, so that the moving plate pushes off the wire harness on the U-shaped block, eliminating the need for manual removal by staff and improving work efficiency.

[0012] In a possible implementation manner, the driving part includes a first gear and a second gear rotatably connected to the side wall of the heat shrinker body. A rotating rod is rotatably connected to the first gear through a rotating shaft. The rotating rod is rotatably connected to the guide rod.

The motor drives the second gear to rotate, the second gear drives the first gear to rotate, the first gear drives the rotating rod to rotate, and the rotating rod will push and pull the guide rod.

[0013] In a possible implementation manner, a sliding groove is opened on the side wall of the U-shaped block. A sliding block slides inside the sliding groove. The sliding block is fixed to the moving plate. The moving plate will drive the sliding block to slide in the sliding groove, which is convenient for improving the stability of the moving plate when it moves.

[0014] In a possible implementation manner, a limiting groove is opened on the U-shaped block. A limiting block slides inside the limiting groove. A spring is arranged in the limiting groove. The limiting block will block the wire harness to prevent the wire harness from slipping out of the U-shaped block. When the moving plate drives the fixed column to push off the wire harness, the moving plate will drive the fixed column to squeeze the limiting block downward. The limiting block slides in the limiting groove, and at the same time, the limiting block will squeeze the spring, which is convenient for pushing the wire harness out of the U-shaped block. When the moving plate moves in the reverse direction, the limiting block resets under the action of the spring.

[0017] In a possible implementation manner, the top end of the spring is fixed to the limiting block, and the bottom end of the spring is fixed to the U-shaped block, preventing the limiting block from falling off the limiting groove.

[0026] This embodiment introduces the specific structure of an auxiliary mechanism for a wire harness heat shrinker, specifically referring to Figures 1-3 as shown, an auxiliary mechanism for a wire harness heat shrinker includes:

[0027] heat shrinker body 1;

[0028] Two U-shaped blocks 3, the two U-shaped blocks 3 are respectively fixed on both sides of the heat shrinker body 1. Pushing parts capable of pushing the wire harness in the U-shaped block 3 are arranged on both sides of the heat shrinker body 1, and driving parts capable of driving the pushing parts are arranged on both sides of the heat shrinker body 1.

[0029] When the wire harness needs to be taken out of the U-shaped block 3 after heat shrinkage, the pushing part includes a movable moving plate 7 on one side of the U-shaped block 3. A guide rod 13 that can slide on a fixed block 8 is fixed on the moving plate 7. The fixed block 8 is fixed on the side of the heat shrinker body 1. The guide rod 13 penetrates through the fixed block 8 and can slide on the fixed block 8. At the same time, the guide rod 13 will drive the moving plate 7 to move, so that the moving plate 7 pushes the wire harness on the U-shaped block 3 away, eliminating the need for manual removal by workers and improving work efficiency.

[0030] At the same time, the driving part includes a first gear 9 and a second gear 14 rotatably connected to the side wall of the heat shrinker body 1.

When the moving plate 7 drives the fixed column 4 to push the wire harness away, the moving plate 7 will drive the fixed column 4 to squeeze the limit block 5 downward. The limit block 5 slides in the limit groove 16. At the same time, the limit block 5 will squeeze the spring 15, which is convenient for pushing the wire harness out of the U-shaped block 3 without manual removal by the staff, improving the work efficiency.
