Description

Technical Field

[0001] This utility model relates to the field of heat shrink tubing processing technology, specifically a heat shrink tubing winding device that facilitates material replacement. Background Technology

[0002] Heat shrink tubing is mostly made of polyolefin material. Its surface has the advantages of corrosion resistance, wear resistance, insulation and waterproofing. It is wrapped or fitted around the outside of the wire harness. After wrapping, the area is heated again with a hot air gun, which can make the heat shrink tubing material shrink quickly and wrap around each wire harness.

[0003] To quickly wind heat shrink tubing material, a winding device can be used. After securing the wire harness, the heat shrink material strip is spirally wound around the outside of the wire harness. After completion, it is heated and tightened. Most of these devices use a frame to install heat shrink rolls. After winding, it is difficult to quickly change the material, and the winding efficiency is difficult to improve.

[0004] Now, a novel heat shrink tubing winding device that facilitates material replacement is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a heat shrink tubing winding device that facilitates material replacement, thereby solving the problem of inconvenient material replacement mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a heat shrink tubing winding device for easy material replacement, comprising a base, a vertical plate fixed to the right side of the top of the base, a through groove horizontally arranged in the center of the vertical plate, a rod movably inserted into the through groove, a partition fixed to the center of the rod, a wire harness arranged on the left side surface of the rod, a top plate horizontally fixed to the top of the left side of the vertical plate, a cavity arranged on the left side of the top plate, a guide rod fixed between the left and right sides of the cavity, a sleeve block movably connected to the outside of the guide rod, a spring fixed between the right side of the sleeve block and the cavity, a movable frame fixed to the bottom of the sleeve block, a limit piece movably sleeved on the outside of the bottom rod of the movable frame, a fixed frame installed on the left side of the top plate and bottom plate, a baffle plate installed on the right side of the fixed frame, and a heat shrink tubing roll movably wound on the outside of the bottom rod of the movable frame.

[0007] As a further technical solution of this utility model, the lower left corner of the movable frame is embedded in the baffle, and the heat shrink sheet is wound around the outside of the wire harness.

[0008] As a further technical solution of this utility model, a chamber is provided at the lower part of the interior of the vertical plate, and a worm gear is movably connected between the left and right sides of the upper part of the chamber, and a worm is movably connected between the front and back sides of the lower part of the chamber. A motor is fixed at the bottom of the rear of the exterior of the vertical plate, and a lead screw is movably connected to the base at the lower left side of the vertical plate. A threaded groove is provided between the left and right sides of the bottom of the partition.

[0009] As a further technical solution of this utility model, the front of the output end of the motor is fixedly connected to the worm gear, the left side of the worm wheel is fixedly connected to the lead screw, and the lead screw is embedded in the thread groove.

[0010] As a further technical solution of this utility model, a screw hole is provided between the left and right ends of the front end of the insertion rod, a positioning ring is movably sleeved on the outside of the insertion rod, and a bolt is threadedly connected to the center of the front end of the positioning ring.

[0011] As a further technical solution of this utility model, the rear of the bolt rod is embedded in the screw hole, and the positioning ring slides left and right along the outer wall of the insertion rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are: this heat shrink tubing winding device that facilitates material replacement not only enables rapid replenishment of winding material and adjustment of winding position, but also prevents the wire harness from loosening;

[0013] (1) By fixing a movable frame at the bottom of the sleeve block, the movable frame is pushed to the right along the inner wall of the cavity, so that the sleeve block squeezes the spring. At this time, the movable frame installed at the bottom of the sleeve block leaves the baffle, and the paper tube of the heat shrink film roll can be removed. Then, new material is replaced, and the movable frame is released again, allowing the sleeve block and spring to return to their original positions, so that the heat shrink film roll is placed between the fixed frame and the movable frame, which does not hinder the winding process and facilitates the disassembly and assembly of the material.

[0014] (2) By setting a chamber in the lower part of the vertical plate, start the motor and rotate the worm gear, rotate the screw in the way of worm gear driving worm wheel, guide the partition with threaded groove to move horizontally, so that the insertion rod enters and exits the through groove laterally, and then adjust the position of the wire harness to receive the heat shrink film roll to make it convenient for the device to attach the heat shrink film roll to the outside of the wire harness from left to right. After the end, reset the insertion rod and other items to the left so as to remove the finished product.

[0015] (3) By attaching a positioning ring to the outside of the insert rod, wrap each group of wire harnesses around the surface of the left side of the insert rod. Then, attach the positioning ring to the outside of the insert rod, align the screw hole and screw in the bolt for reinforcement. As the heat shrink film roll is wound, the wire harness and other objects are restricted from the left side. After the winding is completed, cut the heat shrink film roll and pull the wire harness away from the insert rod. Use a hot air gun to blow the heat shrink film roll to reduce the gap between the insert rod and the wire harness and seal it, thus obtaining the finished product. Attached Figure Description

[0022] Please see Figure 1-4 An embodiment of this utility model provides a heat shrink tubing winding device for easy material replacement, comprising a base 1, a vertical plate 2 fixed to the right side of the top of the base 1, a through groove 4 horizontally arranged in the center of the vertical plate 2, an insert rod 3 movably inserted into the through groove 4, a partition plate 15 fixed to the center of the insert rod 3, a wire harness 16 arranged on the left side surface of the insert rod 3, a top plate 5 horizontally fixed to the top of the left side of the vertical plate 2, a cavity 6 arranged on the left side inside the top plate 5, a guide rod 9 fixed between the left and right sides inside the cavity 6, a sleeve block 8 movably connected to the outside of the guide rod 9, a spring 7 fixed between the right side of the sleeve block 8 and the cavity 6, a movable frame 19 fixed to the bottom of the sleeve block 8, a limit piece 20 movably sleeved on the outside of the bottom rod of the movable frame 19, a fixed frame 10 installed on the left side of the bottom plate of the top plate 5, a baffle 18 installed on the right side of the fixed frame 10, and a heat shrink tubing roll 11 movably wound on the outside of the bottom rod of the movable frame 19;

[0023] The lower left corner of the movable frame 19 is embedded in the baffle 18, and the heat shrink film roll 11 is wound around the outside of the wire harness 16;

[0024] Specifically, such as Figure 1 and Figure 2As shown, the movable frame 19 is moved to the right along the inner wall of the cavity 6, causing the sleeve block 8 to squeeze the spring 7. At this time, the movable frame 19 installed at the bottom of the sleeve block 8 is separated from the baffle 18, and the paper tube of the heat shrink film roll 11 can be removed. Then, new material is replaced. The movable frame 19 is released again, and the sleeve block 8 and spring 7 are allowed to return to their original positions, so that the heat shrink film roll 11 is placed between the fixed frame 10 and the movable frame 19, making it convenient to extract the material.

[0025] A chamber 23 is provided at the bottom inside the vertical plate 2, and a worm gear 22 is movably connected between the left and right sides of the upper part of the chamber 23. A worm 24 is movably connected between the front and back sides of the lower part of the chamber 23. A motor 21 is fixed at the bottom rear of the vertical plate 2. A lead screw 13 is movably connected to the base 1 at the lower left side of the vertical plate 2. A threaded groove 17 is provided between the left and right sides of the bottom of the partition plate 15. The front of the output end of the motor 21 is fixedly connected to the worm 24. The left side of the worm gear 22 is fixedly connected to the lead screw 13. The lead screw 13 is embedded in the threaded groove 17.

[0026] Specifically, such as Figure 1 and Figure 3 As shown, the motor 21 is started and the worm gear 24 is rotated. The screw 13 is rotated by the worm gear 24 driving the worm wheel 22. The partition plate 15 with the threaded groove 17 is guided to move horizontally, so that the insertion rod 3 moves laterally into and out of the through groove 4. Then the position of the wire harness 16 receiving the heat shrink film roll 11 is adjusted, so that the device can fit the heat shrink film roll 11 onto the outside of the wire harness 16 from left to right.

[0027] A screw hole 12 is provided between the left and right sides of the front end of the insertion rod 3. A positioning ring 14 is movably sleeved on the outside of the insertion rod 3, and a bolt 25 is threadedly connected to the center of the front end of the positioning ring 14. The rear of the bolt 25 is embedded in the screw hole 12, and the positioning ring 14 slides left and right along the outer wall of the insertion rod 3.

[0028] Specifically, such as Figure 1 and Figure 4 As shown, wrap each group of wire harnesses 16 around the left side of the insert rod 3, and then attach the positioning ring 14 to the outside of the insert rod 3. After aligning with the screw hole 12, screw in the bolt 25 for reinforcement. As the heat shrink film roll 11 is wound, the wire harnesses 16 and other objects are restricted from the left side. After the winding is completed, cut the heat shrink film roll 11 and pull the wire harnesses 16 away from the insert rod 3. Heating the heat shrink film roll 11 with a hot air gun can reduce the gap created by the insert rod 3.

[0029] Furthermore, the motor 21 is electrically connected to an external PLC control module to control the start and stop of the motor 21 and preset relevant parameters. The electrical connection relationship and control method between them are existing technologies, so they will not be described in detail.

[0030] Working principle: When using this utility model, firstly, move the movable frame 19 to the right along the inner wall of the cavity 6, so that the sleeve 8 squeezes the spring 7. At this time, the movable frame 19 installed at the bottom of the sleeve 8 moves away from the baffle 18, and the paper tube of the heat shrink film roll 11 can be removed. Then, replace with new material, release the movable frame 19 again, and let the sleeve 8 and spring 7 return to their original positions, so that the heat shrink film roll 11 is placed between the fixed frame 10 and the movable frame 19 for extraction. Then, wrap each set of wire harnesses 16 around the surface of the left side of the insertion rod 3, and then fit the positioning ring 14 on its outer side along the insertion rod 3. After aligning with the screw hole 12, screw in the bolt 25 for reinforcement. As the heat shrink film roll 11 is wound around, and the wire harness 16 and other objects are restricted from the left side, the motor 21 is started and the worm gear 24 is rotated. The screw 13 is rotated by the worm gear 24 driving the worm wheel 22, which guides the partition plate 15 with the threaded groove 17 to move horizontally, so that the insertion rod 3 enters and exits the through groove 4 laterally. Then, the position of the wire harness 16 receiving the heat shrink film roll 11 is adjusted so that the device can fit the heat shrink film roll 11 onto the outside of the wire harness 16 from left to right. After the winding is completed, the heat shrink film roll 11 is cut off, and the wire harness 16 is pulled away from the insertion rod 3. The gap created by the insertion rod 3 can be reduced by heating the heat shrink film roll 11 with a hot air gun and sealed.
