Description

Technical Field

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

[0002] Wire harness sleeves are widely used in many fields such as electronics, electrical engineering, and automotive. They primarily protect wire harnesses from external environmental corrosion, abrasion, and mechanical damage, while also serving as insulation and identification functions. To ensure a tight fit between the sleeve and the wire harness for optimal protection, heat-shrink treatment is typically required.

[0003] Chinese patent application CN202421273898.5 discloses a heat shrinking device for automotive wiring harness tubing, including an operating table. The top of the operating table has fixedly connected blocks on its east and west sides. Multiple wiring harness bodies are placed on top of the two blocks, with heat shrinkable tubes fitted at both ends. Pressure plates are located on top of the two blocks, with an electric cylinder output end located in the center of the pressure plate. Heating mechanisms are provided on the outer sides of the heat shrinkable tubes on both sides. This application uses two blocks on top of the operating table to fix the wiring harness bodies to the top of the blocks. The heat shrinkable tubes on both sides are located between heating chamber one and heating chamber two. Hot air is blown into heating chamber one and heating chamber two through multiple pipes by hot air blowers on both sides, and then evenly distributed to the periphery of the heat shrinkable tubes through their own ventilation nets, enabling rapid batch heat shrinking of the heat shrinkable tubes, thereby improving heat shrinking efficiency and quality.

[0004] However, existing heat shrinking devices still have some defects. The heating of different parts of the wire harness sleeve is uneven, which leads to some areas being over-heat-shrinked and damaged, and some areas being under-heat-shrinked and unable to achieve the ideal protective effect. This seriously affects the quality and performance stability of the wire harness sleeve after heat shrinking. Utility Model Content

[0005] To address the aforementioned shortcomings in the existing technology, this utility model provides a wire harness sleeve heat shrink machine. Its purpose is to solve the problems of uneven heating of different parts of the wire harness sleeve, which leads to over-shrinking and damage in some areas, and under-shrinking and failure to achieve the ideal protective effect in other areas, seriously affecting the quality and performance stability of the wire harness sleeve after heat shrinking.

[0006] To achieve the above-mentioned utility model objectives, the technical solution adopted by this utility model is as follows: a wire harness sleeve heat shrinking machine, including a worktable, a heating ring installed on the upper surface of the worktable, a heating mechanism installed on one side of the heating ring, a displacement mechanism installed on the upper surface of the worktable away from the heating ring, a displacement plate installed on the displacement mechanism, a lifting mechanism installed at the top of the displacement plate, a placement plate installed on the lifting mechanism, and a fixing mechanism installed on the placement plate; The heating mechanism includes a heating box fixedly installed on one end of the upper surface of the workbench, a blower connected to one side of the heating box, an air supply pipe installed on the other side of the heating box, a switch valve installed on the air supply pipe, and a nozzle extending into the interior of the heating ring at one end.

[0007] Furthermore, the displacement mechanism includes a connecting plate fixedly installed on the upper surface of the worktable, a drive motor mounted on the connecting plate, a threaded rod connected to the output end of the drive motor, the threaded rod being threadedly connected to the displacement plate, and guide rods connected to both sides of the threaded rod, the guide rods being slidably connected to the displacement plate.

[0008] Furthermore, the lifting mechanism includes a support rod fixedly installed on the top of the displacement plate, a lifting rod sleeved on the support rod, a plurality of positioning holes opened on one side of the lifting rod, and an insert rod sleeved on the top of one side of the support rod, the insert rod being inserted into and connected to the positioning holes.

[0009] Furthermore, the fixing mechanism includes a pair of rectangular slots formed on the upper surface of the placement plate, a slide rod is installed on the rectangular slot, a slider is slidably connected to the slide rod, a telescopic spring is connected to one side of the slider, and a first fixing plate is fixedly connected to the top of the slider.

[0010] Furthermore, a storage drawer is installed at the bottom of the work surface, and a second fixing plate is installed on one side of the storage drawer, with a control panel installed on the second fixing plate.

[0011] Furthermore, the lower surface of the worktable is equipped with a pair of support legs.

[0012] The beneficial effects of this utility model are as follows: This utility model discloses a wire harness sleeve heat shrinking machine. A blower stably delivers heated air from the heating chamber to the heating ring via an air supply pipe, and then evenly sprays it out through nozzles. This uniform hot air delivery method ensures a more even temperature distribution within the heating ring, preventing uneven heating of the wire harness sleeve due to excessively high or low local temperatures. This ensures that all parts of the wire harness sleeve are heated evenly during the heat shrinking process, effectively reducing over- or under-heat shrinking and thus improving the quality and performance stability of the heat shrinking process.

[0013] This utility model discloses a wire harness sleeve heat shrink machine. A drive motor drives a threaded rod to rotate, causing a displacement plate to move smoothly along a guide rod. This, in turn, moves a lifting mechanism, a placement plate, and the wire harness sleeve fixed on the placement plate. By controlling the moving speed and distance of the displacement plate, different parts of the wire harness sleeve can sequentially enter the heating ring to receive uniform heating. This ensures that the entire wire harness sleeve is fully and evenly heated by the hot air, effectively avoiding uneven heating caused by excessively long or short local dwell time of the wire harness sleeve, and significantly improving the heat shrinking effect.

[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0017] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0018] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0019] like Figures 1 to 4 As shown, a wire harness sleeve heat shrinking machine includes a worktable 1, a heating ring 2 installed on the upper surface of the worktable 1, a heating mechanism 3 installed on one side of the heating ring 2, a displacement mechanism 4 installed on the side of the upper surface of the worktable 1 away from the heating ring 2, a displacement plate 5 installed on the displacement mechanism 4, a lifting mechanism 6 installed at the top of the displacement plate 5, a placement plate 7 installed on the lifting mechanism 6, and a fixing mechanism 8 installed on the placement plate 7. The heating mechanism 3 includes a heating box 301 fixedly installed on one end of the upper surface of the workbench 1, a blower 302 connected to one side of the heating box 301, an air supply pipe 303 installed on the other side of the heating box 301, a switch valve 304 installed on the air supply pipe 303, and one end of the air supply pipe 303 extending into the interior of the heating ring 2 and connected to a nozzle 305.

[0020] Through the above scheme, the heating mechanism 3, through the combined use of heating box 301, blower 302 and nozzle 305, realizes the centralized delivery and precise spraying of hot air. Heating box 301 efficiently heats the air, blower 302 provides stable airflow, and air supply pipe 303 delivers hot air to nozzle 305 in heating ring 2, which directly acts on the surface of wire harness sleeve. This avoids the problem of serious heat loss in traditional heating methods, making the heat shrinking process more uniform and efficient, significantly improving the heat shrinking quality of wire harness sleeve, while shortening processing time and improving production efficiency.

[0021] The displacement mechanism 4 includes a connecting plate 401 fixedly installed on the upper surface of the worktable 1. A drive motor 402 is installed on the connecting plate 401. A threaded rod 403 is connected to the output end of the drive motor 402. The threaded rod 403 is threadedly connected to the displacement plate 5. Guide rods 404 are connected to both sides of the threaded rod 403. The guide rods 404 are slidably connected to the displacement plate 5.

[0022] With the above scheme, when the drive motor 402 starts, it drives the threaded rod 403 to rotate. Due to the threaded connection between the threaded rod 403 and the displacement plate 5, the displacement plate 5 can move along the axial direction of the threaded rod 403. To ensure the stability of the movement of the displacement plate 5, guide rods 404 are connected to both sides of the threaded rod 403. The guide rods 404 are slidably connected to the displacement plate 5 and play a guiding role to prevent the displacement plate 5 from deviating during movement.

[0023] The lifting mechanism 6 includes a support rod 601 fixedly installed on the top of the displacement plate 5. A lifting rod 602 is sleeved on the support rod 601. Multiple positioning holes 603 are opened on one side of the lifting rod 602. An insert rod 604 is sleeved on the top of one side of the support rod 601. The insert rod 604 is inserted and connected to the positioning holes 603.

[0024] With the above solution, when it is necessary to adjust the height of the placement plate 7, the staff can pull out the insertion rod 604 from the positioning hole 603, and then manually adjust the height of the lifting rod 602 so that the lifting rod 602 moves up and down on the support rod 601. When the appropriate height is reached, the insertion rod 604 is inserted into the corresponding positioning hole 603 to fix the lifting rod 602, thereby realizing the adjustment of the height of the placement plate 7.

[0025] The fixing mechanism 8 includes a pair of rectangular slots 801 formed on the upper surface of the placement plate 7. A slide rod 802 is installed on the rectangular slot 801. A slider 803 is slidably connected to the slide rod 802. A telescopic spring 804 is connected to one side of the slider 803. A first fixing plate 805 is fixedly connected to the top of the slider 803.

[0026] With the above solution, after the wire harness sleeve is placed on the placement plate 7, the operator can manually push the first fixing plate 805, causing the slider 803 to slide on the slide rod 802. The first fixing plate 805 then moves and approaches the wire harness sleeve. Under the elastic action of the telescopic spring 804, the first fixing plate 805 can tightly clamp the wire harness sleeve, thus fixing the wire harness sleeve. This effectively avoids problems such as poor heat shrinkage or equipment damage caused by the movement of the wire harness sleeve, and improves the stability and safety of the processing.

[0027] A storage drawer 101 is installed at the bottom of the work surface 1, and a second fixing plate 102 is installed on one side of the storage drawer 101. A control panel 103 is installed on the second fixing plate 102.

[0028] Through the above solution, the storage drawer 101 provides convenient storage space for commonly used tools or accessories, making it easy for operators to quickly access them. At the same time, the control panel 103 installed on the second fixing plate 102 integrates various operating functions of the equipment. Users can directly adjust parameters such as heating temperature and displacement speed through the control panel 103, realizing intelligent control of the equipment, simplifying the operation process, improving work efficiency, and enhancing the human-computer interaction experience of the equipment.

[0029] The lower surface of the worktable 1 is fitted with a pair of support legs 9.

[0030] Through the above solution, the support leg 9 provides a stable support foundation for the equipment, ensuring the stability of the equipment during operation.

[0031] The above description is only a preferred embodiment of this utility model patent and is not intended to limit this utility model patent. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this utility model patent should be included within the protection scope of this utility model patent.
