Description

Technical Field

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

[0002] Heat shrink tubing is a specially designed heat shrink sleeve made of polyolefin material. The outer layer is made of high-quality, soft cross-linked polyolefin material and the inner layer is made of hot melt adhesive. The outer layer material has the characteristics of insulation, corrosion resistance and wear resistance, while the inner layer has the advantages of low melting point, waterproof sealing and high adhesion.

[0003] Heat shrink tubing is typically used to wrap and secure products in packaging. Before using heat shrink tubing, it needs to be cut. Currently, most cutting methods are done manually using cutting tools, which is inefficient, poses significant safety risks, and has high production costs. In addition, it is easy to produce uneven cut lengths and irregular cut edges. Therefore, improvements are needed. Utility Model Content

[0025] like Figures 1 to 5As shown, a heat shrink tubing 30 cutting device includes a feed seat 10 and a cutter seat 20. The feed seat 10 is provided with a feed hole, and the cutter seat 20 is provided with a cutting hole. The center points of the diameters of the feed hole and the cutting hole are located on the same axis. A cutter assembly is provided on the cutter seat and is located on one side of the cutter seat 20. The cutter assembly is used to cut the heat shrink tubing 30 delivered from the cutting hole. When cutting the heat shrink tubing 30, the heat shrink tubing 30 is first moved from the feed hole of the feed seat 10 to the cutting hole of the cutter seat 20 by the feeding mechanism. Then, the heat shrink tubing 30 located in the cutting hole of the cutter seat 20 is cut by the cutting assembly, thereby improving the cutting efficiency, reducing the cutting cost, and improving the flatness of the cut of the heat shrink tubing 30 after cutting. In addition, by controlling the cutting speed of the cutting assembly, the cutting length of the heat shrink tubing 30 can be controlled, thereby meeting the cutting requirements of heat shrink tubing 30 for products of different specifications.

[0026] The feed seat 10 includes a feed bracket 11 and a feed block 12. The feed bracket 11 is provided with an assembly groove, and the feed block 12 is installed in the assembly groove. The feed hole is provided on the feed block 12. In this embodiment, the feed bracket 11 and the feed block 12 cooperate to form the feed seat 10, so as to facilitate the replacement of the feed block 12 according to the different hole diameters of the heat shrink tubing 30, thereby improving the cutting efficiency of heat shrink tubing 30 of different specifications.

[0027] An extension is provided on the side of the feed block 12 facing the cutter seat 20, and the feed hole passes through the extension. In this embodiment, an extension is provided on the feed block 12 to improve the stability of the heat shrink tubing 30 when it moves from the feed seat 10 to the cutter seat.

[0028] The cutter holder 20 includes a cutter mounting plate 21, a cutter drive 22, and a cutter block 24. A cutting hole is located on the cutter mounting plate 21, and the cutter drive 22 is located on one side of the cutter mounting plate 21. The cutter drive 22 is connected to the cutter block 24 and drives the cutter block 24 to cut the heat shrink tubing 30 located within the cutting hole. In this embodiment, by setting the cutter drive 22 and the cutter block 24 on the cutter mounting plate 21, the cutter drive 22 drives the cutter block 24 to cut the heat shrink tubing 30.

[0029] The cutting block 24 includes a first cutting blade 241 and a second cutting blade 242 corresponding to the first cutting blade 241. The cutting blade drive 22 is connected to the first cutting blade 241 in a driving connection, and the second cutting blade 242 is fixedly mounted on the cutting blade mounting plate 21. In this embodiment, the cutting block 24 includes a first cutting blade 241 and a second cutting blade 242. The second cutting blade 242 is fixedly mounted on the cutting blade mounting plate 21. The cutting blade drive 22 drives the first cutting blade 241 to move toward the second cutting blade 242 and cooperates with the second cutting blade 242 to cut the heat shrink tubing 30.

[0030] The first cutting blade 241 includes a first cutting block 2411 and a second cutting block 2412. The first cutting block 2411 and the second cutting block 2412 are spaced apart to form a cutting groove 2413. The second cutting blade 242 includes a third cutting block 2421. When the first cutting blade 241 and the second cutting blade 242 approach each other for cutting, the third cutting block 2421 enters the cutting groove 2413. In this embodiment, the first cutting blade 241 forms a cutting groove 2413 through the spaced first cutting block 2411 and the second cutting block 2412, which, in conjunction with the third cutting block 2421 on the second cutting blade 242, facilitates the positioning and cutting of the heat shrink tubing 30, thereby improving the flatness of the cut of the heat shrink tubing 30.

[0031] The cutter mounting plate 21 includes a mounting base 25 and a mounting cover plate 26. The mounting base 25 has a mounting groove 251, and a transmission rod 23 is disposed within the mounting groove 251. The transmission rod 23 is connected to the cutter drive component 22 and the cutter block 24, respectively. The mounting cover plate 26 closes to the mounting groove 251. In this embodiment, by providing a mounting groove 251 on the mounting base 25 and then covering the mounting groove 251 with the mounting cover plate 26, the space within the mounting groove 251 is effectively protected.

[0032] A limiting block 27 is provided in the mounting slot 251, a first limiting slot is provided on the mounting base 25, and a second limiting slot is provided on the transmission rod 23. The two ends of the limiting block 27 are located in the first limiting slot and the second limiting slot, respectively. In this embodiment, the limiting block 27 is used to protect and limit the transmission rod 23.

[0033] The cutter drive unit 22 includes a cutter cylinder, and a connecting groove is provided on the side of the transmission rod 23 facing the cutter cylinder. The piston rod end of the cutter cylinder is fixedly disposed in the connecting groove. In this embodiment, the connecting groove is provided on the transmission rod 23 to facilitate the fixed connection between the piston rod end of the cutter cylinder and the transmission rod 23.

[0034] The cutter holder 20 is provided with a mounting groove 251, and a cutting block 28 is provided on the mounting groove 251. Cutting holes are provided on the cutting block 28. In this embodiment, the cutting block 28 is provided on the cutter holder 20 to facilitate its adaptation to the feeding block 12. Different specifications of cutting blocks 28 and feeding blocks 12 can be replaced according to different specifications of heat shrink tubing 30, thereby facilitating the cutting of heat shrink tubing 30 of multiple specifications.
