Description

Technical Field

[0001] This invention relates to the field of winding apparatus technology, specifically a winding apparatus for film production. Background Technology

[0002] Thin film is a thin, soft, transparent sheet made of plastics, adhesives, rubber, or other materials. Scientifically, thin film is a two-dimensional material formed by the deposition of atoms, molecules, or ions on the surface of a substrate. Examples include optical thin films, composite thin films, superconducting thin films, polyester films, nylon films, and plastic films. Thin films are widely used in industries such as electronics, machinery, and printing.

[0003] According to Chinese Patent No. CN211569587U, a winding device for Bopp film production is provided. This device improves the ease of use by setting up a roller cavity, a roller, a motor cavity, a motor, a first base, a first spring, and a second base. The device also improves the stability during use by setting up a first retaining seat, a second spring, a fixing frame, a roller, a sleeve, a second retaining seat, and a sleeve. However, this device cannot handle dust and impurities in the air above the film. Dust and impurities falling onto the film and being wound can easily cause bulging, resulting in poor film winding effect.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0022] like Figures 1-7As shown, the present invention provides a technical solution: a winding device for film production, including a worktable 1, a mounting plate 2 disposed on the upper part of the worktable 1, a first motor 4 fixedly mounted on one side of the mounting plate 2, a winding roller 5 disposed on the upper part of the worktable 1, a guide roller 6 disposed on the upper part of the worktable 1, and a processing assembly 3 disposed on the upper part of the worktable 1. The processing assembly 3 includes a dust removal mechanism 31 disposed on the upper part of the worktable 1, a disassembly and assembly mechanism 32 disposed on one side of the worktable 1, and a fixing mechanism 33 disposed on the upper part of the worktable 1. The mounting plate 2 contains... The workbench 1 is equipped with a pressing mechanism 34. The dust removal mechanism 31 includes a base 311 fixedly installed on one side of the workbench 1. A second motor 312 is fixedly installed on the upper part of the base 311. A lead screw 313 is fixedly connected to the output end of the second motor 312. A first slide groove 314 is opened on the upper part of the workbench 1. A connecting block 315 is slidably connected to the inner wall of the groove. A slide plate 316 is fixedly connected to the top of the connecting block 315. A suction fan 317 is fixedly installed on the upper part of the slide plate 316. A second slide groove 318 is opened on the upper part of the workbench 1. A connecting... The connecting column 319 has a ball bearing 3110 at its bottom. The lead screw 313 is rotatably connected to the worktable 1 via a bearing. The connecting block 315 is threaded onto the outer wall of the lead screw 313. The sliding plate 316 is slidably connected to the worktable 1 via the connecting block 315. The suction fan 317 collects dust, achieving a dust removal effect and preventing dust and impurities from falling onto the surface of the film, thus preventing bulging after the film is wrapped. Through the cooperation of the lead screw 313, connecting block 315, and sliding plate 316, the second motor 312 drives... Rotating the lead screw 313 causes the suction fan 317, which is fixedly mounted on the upper part of the slide plate 316, to reciprocate left and right, thereby increasing the working range of the suction fan 317 and improving the dust removal effect. There are four balls 3110, arranged in pairs and symmetrically distributed in the worktable 1. The top of the connecting column 319 is fixedly connected to the slide plate 316. Through the cooperation between the connecting column 319 and the balls 3110, the relative friction between the suction fan 317 and the worktable 1 is reduced, thereby reducing the effect of the second motor 312 and saving resources.

[0023] In this embodiment, when the device is in use, the second motor 312 and the suction fan 317 are first turned on manually. The output end of the second motor 312 rotates in both directions, driving the lead screw 313 to rotate. This causes the connecting block 315, which is threaded onto the outer wall of the lead screw 313, to move to the left or right. This causes the sliding plate 316, which is fixedly connected to the top of the connecting block 315, to reciprocate left and right on the upper part of the worktable 1. The reciprocating left and right movement of the sliding plate 316 drives the suction fan 317, which is fixedly installed on its upper part, to reciprocate left and right on the upper part of the worktable 1, thereby increasing the working range of the suction fan 317. Thus, the suction fan 317 can achieve a highly efficient dust removal effect. Example 2

[0024] Based on Example 1, a preferred embodiment of the winding apparatus for film production provided by the present invention is as follows: Figures 1-7 As shown: The disassembly and assembly mechanism 32 includes a collection pipe 321 connected to one side of the suction fan 317. A filter plate 322 is provided at the bottom of the collection pipe 321. A mounting base 323 is fixedly connected to the outer wall of the collection pipe 321. A first telescopic column 324 is provided at the bottom of the mounting base 323. A limit block 326 is fixedly connected to the bottom of the first telescopic column 324. A first spring 325 is fixedly connected to the upper part of the limit block 326. A fixing plate 327 is fixedly connected to the top of the first telescopic column 324. An arc-shaped plate 328 is fixedly connected to one end of the fixing plate 327. A third sliding groove 329 is provided on the inner wall of the mounting base 323. A first sliding rod 3210 is fixedly connected to the inner wall of the groove. A sliding rod 3210 is slidably connected to the outer wall of the first sliding rod 3210. The first slider 3211 and the top of the first spring 325 are fixedly connected to the mounting base 323. The first telescopic column 324 is slidably connected to the mounting base 323 through the first spring 325. The first slider 3211 is slidably connected to the fixing plate 327. The fixing plate 327 is slidably connected to the mounting base 323 through the first slider 3211. The dust absorbed by the suction fan 317 can be filtered through the filter plate 322, thereby expelling clean air. Through the cooperation of the first telescopic column 324, the first spring 325, the limiting block 326, and the first slider 3211, the filter plate 322 can be easily disassembled and cleaned manually, preventing the filter holes of the filter plate 322 from becoming clogged, thereby improving the filtration effect of the filter plate 322.

[0025] In this embodiment, when the filter plate 322 is cleaned and installed, it is first manually inserted into the middle position between the fixing plate 327 and the collection tube 321. Under the limiting action of the first slider 3211 and the first sliding rod 3210, the first spring 325 causes the limiting block 326 to press upward against the first telescopic column 324 under the action of elastic force, thereby causing the first telescopic column 324 to press upward against the fixing plate 327, and then the fixing plate 327 to press upward against the filter plate 322, thereby achieving the effect of fixing the filter plate 322. The operation is simple and convenient. Example 3

[0026] Based on Example 1, a preferred embodiment of the winding apparatus for film production provided by the present invention is as follows: Figures 1-7As shown: The fixing mechanism 33 includes a groove 331 formed on the outer wall of the winding roller 5. The inner wall of the groove has an inner groove 332. A second spring 333 is fixedly connected to the inner wall of the inner groove 332. A second telescopic column 334 is fixedly connected to one end of the second spring 333. A rectangular plate 335 is fixedly connected to the end of the second telescopic column 334 away from the second spring 333. An anti-slip block 337 is fixedly connected to one side of the rectangular plate 335. A first rotating shaft 336 is fixedly connected inside the winding roller 5. The second telescopic column 334 is slidably connected to the winding roller 5 through the second spring 333. The first rotating shaft 336 is fixedly connected to the output end of the first motor 4. The winding roller 5 is rotatably connected to the mounting plate 2 through the first rotating shaft 336. There are several anti-slip blocks 337, which are equidistantly distributed on one side of the rectangular plate 335. Through the cooperation of the second spring 333, the second telescopic column 334, and the rectangular plate 335, the film can be fixed in the groove 331 formed on the outer wall of the winding roller 5, thereby making it easier to wind the film.

[0027] In this embodiment, when fixing the film, the rectangular plate 335 is first pushed to the left manually, and then the film is placed in the groove 331. Then the rectangular plate 335 is released, and the second telescopic column 334 moves to the right under the action of the second spring 333. This causes the second telescopic column 334 to press against the rectangular plate 335 to the right, which in turn causes the rectangular plate 335 to press against the film to the right, thereby achieving the effect of fixing the film. At the same time, the anti-slip block 337 makes it less likely for the film to slip after fixing, thus improving the fixing effect of the film. Then, the first motor 4 can be started manually to drive the first rotating shaft 336 to rotate, so that the winding roller 5, with the cooperation of the guide roller 6, winds the film. Example 4

[0028] Based on Example 1, a preferred embodiment of the winding apparatus for film production provided by the present invention is as follows: Figures 1-7As shown: The clamping mechanism 34 includes a fourth slide groove 341 formed on one side of the mounting plate 2. A second slide rod 342 is fixedly connected to the inner wall of the groove. A second slider 343 is slidably connected to the outer wall of the second slide rod 342. A second rotating shaft 345 is rotatably connected to one side of the second slider 343 via a bearing. A pressure roller 346 is fixedly connected to the outer wall of the second rotating shaft 345. A third spring 344 is fixedly connected to the inner wall of the fourth slide groove 341. A slot 347 is formed on the inner wall of the fourth slide groove 341. A locking block 348 is slidably connected to the inner wall of the slot. The top of the third spring 344 is fixedly connected to the second slider 343. The pressure roller 346 is rotatably connected to the mounting plate 2 via the second rotating shaft 345. The second rotating shaft 345 is slidably connected to the mounting plate 2 via the second slider 343. The locking block 348 is fixedly connected to the second slider 343. Through the cooperation of the pressure roller 346, the second rotating shaft 345, the third spring 344, the second slider 343, and the second sliding rod 342, the pressure roller 346 is brought into contact with the winding roller 5. When the film is wound on the surface of the winding roller 5, it can play a pressing role, thereby making the winding effect of the film better. The locking block 348 makes the second slider 343 more stable during the sliding process.

[0029] In this embodiment, when the winding roller 5 winds the film, the third spring 344, under the action of elastic force, causes the second slider 343 to be subjected to an upward pressure, thereby causing the second rotating shaft 345, which is rotatably connected to one side of the second slider 343 via a bearing, to be subjected to an upward pressure. This ensures that the pressure roller 346, which is fixedly connected to the outer wall of the second rotating shaft 345, is always in contact with the winding roller 5. The pressure roller 346 can press the film upward, thereby making the film tightly adhere to the winding roller 5, thus improving the winding effect of the film.
