Abstract
Description
Technical Field
[0001] The utility model relates to the field of pre-coating film production, in particular to a tensioning mechanism for pre-coating film production. Background Art
[0002] Pre-coating refers to the process of pre-gluing and rewinding plastic film before laminating it with paper printed products. The pre-coating factory first applies glue on the film according to the specifications and format, then rewinds it for the user to choose, and then laminates it with the printed product. Laminating, also known as film pasting, is a processing technology that coats plastic film with adhesive and bonds it to paper printed products after heating and pressurizing to form a paper-plastic integrated product. The printed product after lamination has a thin and transparent plastic film on the surface, which makes the surface smoother and brighter, thereby improving the gloss and fastness of the printed product, making the color of the image and text more vivid and three-dimensional, and at the same time playing the role of waterproof, anti-fouling, wear-resistant, fold-resistant, and chemical corrosion-resistant.
[0003] The current pre-coated film cannot adjust the tension during the lamination process. Too much or too little tension will seriously affect the use effect. In addition, due to long-term contact with air during the lamination process, dust is easily attached to the surface of the pre-coated film. If the dust is not cleaned, it will seriously affect the lamination effect and thus affect the product quality. Therefore, this application proposes a tensioning mechanism for pre-coated film production to meet the needs. Utility Model Content

[0027] The embodiments of the present application solve the problems in the prior art by providing a tensioning mechanism for pre-coated film production.
[0028] The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows:
[0029] The specific structure of this embodiment is as follows: Figures 1 to 6 As shown, a tensioning mechanism for pre-coated film production includes a box body 1, with inlet and outlet ports 2 on both sides of the box body 1, two groups of tensioning rollers 3 are arranged inside the box body 1, and an adjustment component 4 is arranged at the connection between the tensioning roller 3 and the box body 1, and a group of inlet and outlet ports 2 are provided with cleaning components 5 above and below.
[0030] In some examples, the adjustment component 4 includes an adjustment slot 41 and an adjustment rod 42. The adjustment slot 41 is opened on the inner walls on both sides of the box body 1 and is connected to the interior of the box body 1. The adjustment rod 42 is rotatably connected to both ends of the tensioning roller 3 and is slidably connected to the adjustment slot 41. The height of the tensioning roller 3 can be adjusted by sliding the adjustment rod 42 along the adjustment slot 41, thereby adjusting the tension of the pre-coated film.
[0031] In some examples, the adjustment component 4 also includes a fixing hole 43, a fixing block 44, a through slot 45 and a fixing rod 46. The fixing holes 43 are provided in several groups and are opened on both sides of the adjustment slot 41. The through slot 45 runs through the middle of the fixing block 44. The fixing block 44 is sleeved and slidably connected to the outer periphery of the adjustment rod 42. The fixing rod 46 is fixedly connected to the inner side of the fixing block 44 and is adapted to the size of the fixing hole 43. The height of the adjusting rod 42 can be adjusted by moving the fixing rod 46 out of the fixing hole 43, and the adjusting rod 42 can be fixed at the current height by inserting the fixing rod 46 into the fixing hole 43.
[0032] In some examples, the adjustment component 4 also includes a slide groove 47, a slider 48 and a spring 49. The slide groove 47 is opened on the top surface of the adjustment rod 42, the slider 48 is fixedly connected to the top inner wall of the through groove 45 and is slidably connected to the slide groove 47, and the spring 49 is fixedly installed inside the slide groove 47 and its two ends are respectively fixedly connected to one side of the slider 48 and the inner wall of one side of the slide groove 47. Pulling the fixed block 44 outward can drive the slider 48 to slide outward along the slide groove 47 and squeeze the spring 49. Release the fixed block 44, the spring 49 rebounds and drives the fixed block 44 to move inward through the slider 48.
[0033] In some examples, the cleaning component 5 includes a mounting block 51, a splint 52 and cleaning cotton 53. The mounting block 51 is fixedly connected to one side of the box body 1 and is located above and below a group of inlet and outlet ports 2. The splint 52 is movably connected to both sides of the mounting block 51. The cleaning cotton 53 is movably connected between the two groups of splints 52 and is adapted to the size of the pre-coated film. The cleaning cotton 53 is placed on one side of the mounting block 51 close to the inlet and outlet ports 2, and then the cleaning cotton 53 is fixed in the current position by the splint 52. At this time, the pre-coated film can be cleaned when it passes through the inlet and outlet ports 2.
[0034] In some examples, the cleaning component 5 also includes a mounting groove 54, a mounting plate 55, a guide groove 56 and a guide block 57. The mounting groove 54 is opened inside the mounting block 51 and is connected to the outside. The mounting plate 55 is slidably connected to the mounting groove 54 and fixedly connected to the inner side of the splint 52. The guide groove 56 is opened on the inner wall at the bottom of the mounting groove 54. The guide block 57 is fixedly connected to the bottom of the mounting plate 55 and slidably connected to the guide groove 56. Sliding the mounting plate 55 along the mounting groove 54 can drive the splint 52 to move synchronously. During this process, the guide block 57 slides synchronously with the mounting plate 55 along the guide groove 56 and limits and guides the mounting plate 55.
[0035] In some examples, the cleaning component 5 also includes an empty slot 58, a gear 59, a latch tooth 510 and a rotating rod 511. The empty slot 58 is opened between the two groups of mounting slots 54 and is connected to the two groups of mounting slots 54. The empty slot 58 is connected to the outside world. The gear 59 is rotatably connected to the empty slot 58. The latch tooth 510 is fixedly connected to a side of the mounting plate 55 close to the gear 59 and meshes with the gear 59. The rotating rod 511 is fixedly connected to the middle of the gear 59 and extends to the outside world through the empty slot 58. Rotating the rotating rod 511 can drive the gear 59 to rotate. Since the latch tooth 510 is meshed with the gear 59 and the latch tooth 510 is fixedly connected to the mounting plate 55, the gear 59 will drive the mounting plate 55 to move laterally through the latch tooth 510, thereby adjusting the position of the splint 52.
[0036] In a specific application scenario, first, the rotating rod 511 is rotated clockwise to drive the gear 59 to rotate synchronously. Since the latch tooth 510 is meshed with the gear 59 and the latch tooth 510 is fixedly connected to the mounting plate 55, and the guide block 57 is fixedly connected to the bottom of the mounting plate 55 and slidably connected to the guide slot 56, the gear 59 will drive the mounting plate 55 to slide outward along the mounting slot 54 through the latch tooth 510. During this process, the clamping plate 52 moves outward synchronously with the mounting plate 55. When the spacing between the two sets of clamping plates 52 is greater than the length of the cleaning cotton 53, the cleaning cotton 53 is placed between the two sets of clamping plates 52, and then the rotating rod 511 is rotated in the opposite direction to drive the mounting plate 55 to slide inward along the mounting slot 54 through the gear 59. When the clamping plate 52 moves synchronously with the mounting plate 55 until it is tightly fitted with the two ends of the cleaning cotton 53, the cleaning cotton 53 can be fixed in the current position. At this time, the cleaning cotton 53 can be When the pre-coated film passes through the inlet and outlet 2, the cleaning cotton 53 is cleaned. When the cleaning efficiency of the cleaning cotton 53 decreases, the rotating rod 511 is rotated clockwise again to move the clamping plate 52 outward, and the cleaning cotton 53 can be removed for replacement. When the tension of the pre-coated film needs to be adjusted, the fixing block 44 is first pulled outward to drive the slider 48 to slide outward along the slide groove 47 and squeeze the spring 49. When the fixing rod 46 moves outward with the fixing block 44 until it moves out of the fixing hole 43, the adjusting rod 42 is slid along the adjusting groove 41 to adjust the height of the tensioning roller 3. After adjusting to the appropriate height, the fixing block 44 is released, the spring 49 rebounds and drives the fixing block 44 to move inward through the slider 48. When the fixing rod 46 moves inward with the fixing block 44 until it is inserted into the fixing hole 43 of the current height, the tensioning roller 3 can be fixed at the current height, and the adjustment of the pre-coated film tension can be completed at this time.
[0037] By adopting the above technical solution: not only can the tension of the pre-coated film be adjusted by adjusting the height of the tensioning roller, so that the device can be suitable for pre-coated films with different requirements, but also the surface of the pre-coated film can be cleaned when it passes through the inlet and outlet, so as to avoid dust adhering to the surface of the pre-coated film and affecting the product quality.
[0038] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the scope of protection of the present invention.
