Description

Technical Field

[0001] The present invention relates to the technical field of PVC heat-shrinkable tube winding, and specifically relates to a PVC heat-shrinkable tube winding device. Background Art

[0002] PVC heat-shrinkable tube is a material with the special function of shrinking when heated. Its main component is polyvinyl chloride (PVC). It can shrink when heated above 98°C, is easy to use, and is widely used in various application scenarios that require insulation and protection. In the production and processing process of PVC heat-shrinkable tubes, the winding link is crucial and a winding device is needed.

[0003] After retrieval, a Chinese patent with the publication number CN219859829U discloses a heat-shrinkable tube winding device, including a heat-shrinkable tube machine mechanism. The heat-shrinkable tube machine mechanism includes a heat-shrinkable tube machine, a discharge port, and a heat-shrinkable tube machine support column. The discharge port is fixedly connected to the heat-shrinkable tube machine, and the bottom of the heat-shrinkable tube machine is fixedly connected to the heat-shrinkable tube machine support column. There is a telescoping machine mechanism. The telescoping machine mechanism includes a telescoping machine. A telescoping machine support is placed on the ground beside the heat-shrinkable tube machine. The telescoping machine support is fixedly connected to the telescoping machine. A motor frame is bolted to the telescoping machine. A motor is fixedly connected to the motor frame. A winding frame is threadedly connected to the motor. The connecting rod of the winding frame is an arc-shaped rod structure. The winding of the heat-shrinkable tube is realized by the telescoping of the telescoping machine. The arc-shaped rod fits the shape of the heat-shrinkable tube, making the winding frame more fitting and more uniform when winding the heat-shrinkable tube, improving the stability of the device's operation. However, there are still the following problems:

[0004] 1. The existing winding device is not convenient for disassembling the PVC heat-shrinkable tube winding reel. It is very troublesome to disassemble and replace the next winding reel after winding is completed, thus reducing the work efficiency. Moreover, it is not convenient to replace different types of winding reels according to different specifications of PVC heat-shrinkable tubes, reducing the practicality of the device;

[0005] 2. When winding the PVC heat-shrinkable tube, the heat dissipation effect is poor. The heat dissipation effect through only air circulation is limited, resulting in the PVC heat-shrinkable tubes being easily stuck together during winding, which will damage the PVC heat-shrinkable tubes, causing economic losses and unable to meet the needs of users;

[0006] 3. When winding the PVC heat-shrinkable tube, it is impossible to perform limiting, so that the PVC heat-shrinkable tube is prone to being uneven during winding, resulting in easy deformation, which makes the PVC heat-shrinkable tube prone to problems during subsequent use, and at the same time reduces the stability during winding.

[0040] Especially in the present invention, the vertical plate 5 includes a cooling box 603. The rear end of the cooling box 603 is fixedly connected to the front end of the vertical plate 5. A second servo motor 605 is fixedly connected to the rear end of the inner cavity of the cooling box 603. The output end of the second servo motor 605 is fixedly connected to a rotating rod 604.

[0047] During use, when the cooler 602 is refrigerating, the radiator 601 is turned on.

[0048] Particularly in the present invention, the limiting component 7 includes a support plate 704. The bottom of the support plate 704 is fixedly connected to the top of the winding table 1.

The front end of the movable plate 705 is movably connected to a limiting wheel 701 through a first bearing.

[0049] During use, when winding, the first cylinder 706 drives the movable plate 705 to move inward, and the movable plate 705 drives the limiting wheel 701 to move inward, which can limit the PVC heat shrinkable tube passing through it, making it more stable during winding and preventing unevenness from affecting winding.

[0050] Particularly in the present invention, a first sliding rod 702 is fixedly connected to the top of the winding table 1. The outer surface of the first sliding rod 702 is slidably connected to a first sliding sleeve 703. The rear end of the first sliding sleeve 703 is movably connected to the front end of the limiting wheel 701 through a second bearing.

[0051] During use, through the provided guiding block 11 and guiding rail 10, the limiting wheel 701 can be more stable when moving up and down.

[0052] Particularly in the present invention, guiding rails 10 are fixedly connected to the top and bottom of the rear end of the inner cavity of the disassembly box 301. A guiding block 11 is fixedly connected to the rear end of the connecting plate 302. The outer surface of the guiding block 11 is slidably connected to the inner surface of the guiding rail 10.

[0053] During use, through the provided guiding block 11 and guiding rail 10, the stability of the connecting plate 302 when moving up and down can be improved.

[0054] Particularly in the present invention, clamping plates 8 are fixedly connected to both ends of the front end of the vertical plate 5. The bottom of the clamping plate 8 is fixedly connected to the top of the winding table 1.

[0055] During use, through the provided clamping plates 8, the vertical plate 5 can be supported and fixed, making it more stable during operation.

[0056] Particularly in the present invention, one side of the front end of the vertical plate 5 is fixedly connected to a second sliding rod 12. A second sliding sleeve 13 is slidably connected to the outer surface of the second sliding rod 12, and the bottom of the second sliding sleeve 13 is fixedly connected to the top of the first servo motor 4.

[0057] During use, by means of the provided second sliding sleeve 12 and second sliding rod 13, the first servo motor 4 can move more stably back and forth.

[0058] The present invention is used in the following steps:

[0059] S1: First, pass the PVC heat-shrinkable tube through the limiting wheel 701 and fix it on the winding drum 2. At the same time, the PVC heat-shrinkable tube is located at the front end of the cooling box 603. Then, open the first cylinder 706. The first cylinder 706 drives the movable plate 705 to move inwards, and the movable plate 705 drives the limiting wheel 701 to move inwards, so as to limit the passed PVC heat-shrinkable tube and make it more stable during winding, preventing unevenness from affecting the winding.

[0060] S2: Then, turn on the first servo motor 4. The first servo motor 4 drives the disassembly component 3 to rotate, and the disassembly component 3 drives the winding drum 2 to rotate, so as to wind the PVC heat-shrinkable tube. At the same time, turn on the second cylinder 9. The second cylinder 9 pushes the first servo motor 4 and the winding drum 2 to move forward, so that the PVC heat-shrinkable tube can be evenly wound on the winding drum 2.

[0061] S3: Then, when winding the PVC heat-shrinkable tube, turn on the cooler 602 to cool the inside of the cooling box 603. At the same time, turn on the radiator 601 to dissipate heat from the cooler 602. The heat is transferred from the heat source at the bottom of the radiator 601 to the heat dissipation fins at the top of the radiator 601 through high thermal conductivity materials such as copper and aluminum. Then, through the air circulation, the heat generated by the cooling of the cooler 602 can be discharged, preventing heat from entering the cooling box 603 and affecting the heat dissipation.

[0062] S4: Then, turn on the second servo motor 605. The second servo motor 605 drives the rotating rod 604 to rotate, and the rotating rod 604 drives the fan blade 606 to rotate. Air is introduced through the air inlet 608, and cold air is blown towards the wound PVC heat-shrinkable tube through the air outlet 607, so as to efficiently dissipate heat from it and prevent the produced PVC heat-shrinkable tube from sticking.

[0063] S5: While blowing and dissipating heat, filter through the dust filter plate 609 to prevent dust from being blown towards the PVC heat-shrinkable tube, thereby preventing dust from adhering to the surface of the produced PVC heat-shrinkable tube and preventing it from being affected.

[0064] S6: After the winding is completed, the PVC heat-shrinkable tube is cut off. The bidirectional motor 303 is turned on. The bidirectional motor 303 drives the threaded rod 304 to rotate. The threaded rod 304 drives the threaded block 305 to move outward. The threaded block 305 drives the connecting plate 302 to move outward. The connecting plate 302 drives the fixed angle bracket 306 to move outward, which can cancel the fixation of the winding drum 2, facilitating the removal of the winding drum 2 after the winding is completed for replacement. There is no need for manual disassembly by the staff, effectively improving the work efficiency. At the same time, it is convenient to replace the winding drum 2 of the main body according to the specifications of the PVC heat-shrinkable tube, reducing the trouble of the user;

[0065] S7: After removal, the replaced winding drum 2 is placed inside the fixed angle bracket 306. Then the bidirectional motor 303 is reversed. The bidirectional motor 303 drives the threaded rod 304 to reverse. The threaded rod 304 drives the threaded block 305 to move inward. The threaded block 305 drives the connecting plate 302 to move inward. The connecting plate 302 drives the fixed angle bracket 306 to move inward and fixes the winding drum 2. And through the limiting angle plate provided inside the fixed angle bracket 306, the end face of the winding drum 2 can be limited, effectively preventing the winding drum 2 from skewing;

[0066] S8: Then the first cylinder 706 is turned on to drive the movable plate 705 to move outward. The movable plate 705 drives the limiting wheel 701 to move outward to cancel the limit. The PVC heat-shrinkable tube is passed through the limiting wheel 701 again and fixed on the winding drum 2. The first cylinder 706 is turned on. The first cylinder 706 drives the movable plate 705 to move inward. The movable plate 705 drives the limiting wheel 701 to move inward, which can perform the limit and facilitate a quick entry into the next work.

[0067] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0068] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
