Description

Technical Field

[0001] This utility model relates to the technical field of membrane processing equipment, and in particular to a laser membrane separation device. Background Technology

[0002] In today's packaging, printing, and decoration industries, laser film, with its unique optical effects such as vibrant colors, strong gloss, and exquisite patterns, is widely used to enhance product appearance and increase added value. It is commonly found on the outer packaging of various commodities, including food packaging, cosmetic boxes, and tobacco and alcohol labels, and market demand continues to grow. Laser film processing often involves laminating transfer film with the original film to achieve multi-functional integration. However, in product recycling or subsequent reprocessing stages, the transfer film needs to be separated from the other film materials. For example, Chinese patent document CN218144895U discloses a rapid printing and peeling device for laser film, which includes a housing and a feeding roller. The feeding roller is movably connected to one side of the housing. A set of winding drums is respectively arranged at both ends of the other side of the housing. A set of side plates is movably connected to both ends of the winding drums. A set of guide rollers is movably connected to both ends of the housing. A set of limiting plates is movably connected to both ends of the guide rollers. A threaded groove is formed at the top of one end of each limiting plate. A bidirectional threaded shaft is movably connected inside the threaded groove. The bidirectional threaded shaft is movably connected to the housing. The bidirectional threaded shaft passes through one end of the housing and extends to the outside of the housing, where a rotating wheel is fixedly connected. A limiting rod is fixedly connected to the bottom of the housing. In this way, when the laser film passes between the two guide rollers, the two limiting plates can limit the movement of the laser film.

[0003] However, existing rapid printing and peeling devices for laser film have the following shortcomings in practical use: their bidirectional threaded rods can only drive the two limiting plates to move closer or further apart from each other around the center point between the two ends of the guide roller. When the center point between the two ends of the winding drum and the center point on the guide roller shift due to loading and unloading, the two limiting plates cannot align the center point between the two ends of the laser film with the center point on the winding drum. This results in wrinkles and folds appearing on the laser film as it is wound onto the winding drum, leading to poor quality of the laser film winding. In view of this, the laser film separation device of this application is proposed. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a laser film separation device that adjusts the center position of the laser film according to the center position on the winding drum, so as to avoid wrinkles and folds in the wound laser film and improve the winding quality of the laser film.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A laser membrane separation device includes a guide roller and a take-up roller, and further includes:

[0007] Frame; and

[0008] A limiting assembly includes a support plate and two limiting members. The support plate is rotatably mounted on the frame and located between the film taking roller and the film guiding roller. The two limiting members are adjustablely mounted on both ends of the support plate. Each limiting member includes a slide block and a limiting post. The slide block is adjustablely mounted on the support plate, and the limiting post is rotatably mounted on the slide block. The axis of the limiting post is perpendicular to the sliding direction of the slide block. The two slide blocks respectively drive the two limiting posts to abut against both ends of the laser film, so that the two limiting posts limit the laser film.

[0009] Optionally, the support plate is provided with a slide rail, and the slide block is provided with a slide groove, which engages with the slide rail.

[0010] Optionally, the limiting member further includes a locking rod, the slide rail has a sliding hole, the slide block has a locking hole, and the locking rod passes through the sliding hole and is screwed into the locking hole.

[0011] Optionally, the slide block is further provided with a rotating groove, and the limiting post is engaged with the rotating groove so that the limiting post can rotate relative to the slide block.

[0012] Optionally, the circumferential surface of the limiting post protrudes from one surface of the slide.

[0013] Optionally, the limiting component further includes a sleeve, a push spring, a push rod, and a stop wheel. The sleeve is disposed on the slide block, the push rod is slidably disposed on the sleeve, the stop wheel is rotatably disposed on the end of the push rod away from the sleeve, the push spring is disposed inside the sleeve, the push spring pushes the slide block and the push rod respectively, and the end of the push rod away from the push spring abuts against the laser film.

[0014] Optionally, there is an angle between the push rod and the slide block.

[0015] Optionally, the top rod has a flat portion, and the sleeve has a flat-convex portion, with the flat portion abutting against the flat-convex portion.

Both balancing members are grounded to the laser film, and the two balancing members are used to adjust the angle between the support plate and the surface of the laser film to maintain perpendicularity.

[0017] Optionally, the balancing component includes a support roller, two support blocks, and several support springs. The two ends of the support roller are rotatably connected to the two support blocks, the two support blocks are slidably disposed at the two ends of the support plate, and each support spring is sleeved on the support spring and abuts against the support plate and the support blocks.

[0018] Compared with the prior art, the present invention has at least the following advantages:

[0033] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0034] In the description of the embodiments of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0036] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0037] like Figures 1 to 5 As shown, in one embodiment, a laser film separation device 1 includes a guide roller 10 and a take-up roller 20, as well as a frame 30 and a limiting assembly 40. The limiting assembly 40 includes a support plate 41 and two limiting members 42. The support plate 41 is rotatably mounted on the frame 30 and is located between the take-up roller 20 and the guide roller 10. The two limiting members 42 are adjustablely mounted on both ends of the support plate 41. Each limiting member 42 includes a slide block 421 and a limiting post 422. The slide block 421 is adjustablely mounted on the support plate 41, and the limiting post 422 is rotatably mounted on the slide block 421. The axial direction of the limiting post 422 is perpendicular to the sliding direction of the slide block 421. The two slide blocks 421 respectively drive the two limiting posts 422 to abut against both ends of the laser film, so that the two limiting posts 422 limit the laser film.

[0038] It should be noted that cylinders are provided on the outer surfaces of both ends of the support plate 41, and the cylinders are located at the center of the end of the support plate 41. Both cylinders are rotatably connected to the two opposing sides of the frame 30, so that the support plate 41 can rotate relative to the frame 30. The support plate 41 is located between the guide roller 10 and the take-up roller 20. Since the cylinder is provided at the center of the end of the support plate 41, when the support plate 41 rotates relative to the frame 30, the two sides of the support plate 41 rotate around the axis of a cylinder. Furthermore, the support plate 41 has a frame structure, allowing the laser film to pass through the support plate 41 and wrap around the take-up roller 20 after exiting the guide roller 10. Furthermore, both limiting members 42 are slidably mounted on the support plate 41, with each limiting member 42 positioned close to one end of the support plate 41. When the laser film passes through the support plate 41, the two limiting members 42 are positioned at opposite ends of the laser film. The adjustable slidability of the two limiting members 42 on the support plate 41 ensures that the two limiting members... The positions of the two limiting members 42 near the two ends of the laser film are adjustable. When the center point between the two ends of the take-up roller 20 is offset from the center point between the two ends of the guide roller 10, the positions of the two limiting members 42 at the two ends of the take-up roller 20 can be adjusted so that the interval between the two limiting members 42 is consistent with the distance between the two ends of the take-up roller 20, so that the center point between the two ends of the laser film can be aligned with the center point on the take-up roller 20, so that wrinkles and folds will not occur when the laser film is wound onto the take-up roller 20.

[0039] It should be noted that the limiting member 42 includes a slide block 421 and a limiting post 422. The slide block 421 is adjustablely mounted on the support plate 41, and the limiting post 422 is rotatably mounted on the slide block 421. The axial direction of the limiting post 422 is perpendicular to the sliding direction of the slide block 421. For example, the two ends of the limiting post 422 are respectively facing the two adjacent opposing ends of two cylinders on the support plate 41. In this way, when the slide block 421 drives the limiting post 422 to slide laterally on the support plate 41, the limiting post 422 can rotate relative to the slide block 421. Furthermore, the two slide blocks 421 respectively drive the two limiting posts 422 to abut against the two ends of the laser film, so that the two limiting posts 422 limit the laser film. Since the two limiting posts 422 can rotate relative to the slide block 421, and the axis of the two limiting posts 422 is perpendicular to the sliding direction of the slide block 421, when the laser film passes through the support plate 41, the two ends of the laser film will drive the two limiting posts 422 to rotate. In this way, when the two limiting posts 422 limit the laser film, the friction between the two limiting posts 422 and the two ends of the laser film is reduced, so as to avoid the two limiting posts 422 damaging the laser film.

[0040] like Figures 2 to 3 , Figure 5As shown, in one embodiment, a slide rail 411 is provided on the support plate 41, and a slide groove 4211 is provided on the slide block 421, which is engaged with the slide rail 411.

[0041] It should be noted that the support plate 41 is provided with slide rails 411 at both ends adjacent to the two cylinders, and both slide rails 411 are located on the inner sidewall of the support plate 41. Slide grooves 4211 are provided at both ends of the slide block 421, and the two slide grooves 4211 respectively engage with the two slide rails 411, allowing the slide block 421 to slide relative to the support plate 41.

[0042] like Figures 2 to 5 As shown, in one embodiment, the limiting member 42 further includes a locking rod 423, a sliding hole 4111 is provided on the slide rail 411, a locking hole 4212 is provided on the slide block 421, and the locking rod 423 passes through the sliding hole 4111 and is screwed into the locking hole 4212.

[0043] It should be noted that the sliding hole 4111 extends from one side of the slide rail 411 to the other side, and extends from one end of the slide rail 411 to the other end. Furthermore, the locking hole 4212 extends from one side of the slide block 421 into the slide groove 4211, and connects to the other side of the slide block 421. When the slide groove 4211 engages with the slide rail 411, the locking hole 4212 can communicate with the sliding hole 4111, allowing the locking rod 423 to be inserted into the sliding hole 4111 from one end of the locking hole 4212 and protrude from the other end. Furthermore, the locking rod 423 is a screw structure, screwed to the locking hole 4212. Thus, when the slide block 421 slides relative to the support plate 41, the locking rod 423 can slide relative to the sliding hole 4111. When the slide block 421 slides to the desired position, the position of the slide block 421 can be adjusted by tightening the locking rod 423.

[0044] like Figures 2 to 7 As shown, in one embodiment, the slide 421 is also provided with a rotating groove 4213, and the limiting post 422 is engaged with the rotating groove 4213 so that the limiting post 422 can rotate relative to the slide 421.

[0045] It should be noted that the slide block 421 is provided with a clearance groove, and the two ends of the clearance groove face the two ends of the support plate 41 adjacent to the two cylinders. Furthermore, the inner sidewalls of the two ends of the clearance groove are respectively provided with rotating grooves 4213, and the two rotating grooves 4213 respectively abut against the two ends of the limiting post 422, so that the limiting post 422 can rotate relative to the slide block 421.

[0046] like Figures 6 to 7 As shown, in one embodiment, the circumferential surface of the limiting post 422 protrudes from one surface of the slide block 421.

[0047] It should be noted that the limiting post 422 has a cylindrical structure, and the inner sidewalls of the two rotating grooves 4213 protrude from one surface of the slide block 421. This allows the circumferential surface of the limiting post 422 to extend from one surface of the slide block 421 when the limiting post 422 rotates onto the slide block 421. For example, both slide blocks 421 slide on the slide rail 411, and the two slide blocks 421 are located at opposite ends of the slide rail 411. The circumferential surfaces of the two limiting posts 422 protrude from the opposite side of the two slide blocks 421. Thus, when the two slide blocks 421 slide close to the laser film for limiting, the two slide blocks 421 will respectively drive the two limiting posts 422 to first come into contact with the laser film, and then cause the two ends of the laser film to drive the two limiting posts 422 to rotate. This reduces the friction between the two limiting posts 422 and the ends of the laser film, preventing the two limiting posts 422 from damaging the laser film.

[0048] like Figures 2 to 10 As shown, in one embodiment, the limiting member 42 further includes a sleeve 424, a push spring 425, a push rod 426, and a stop wheel 427. The sleeve 424 is disposed on the slide block 421, the push rod 426 is slidably disposed on the sleeve 424, and the stop wheel 427 is rotatably disposed on the end of the push rod 426 away from the sleeve 424. The push spring 425 is disposed inside the sleeve 424 and pushes the slide block 421 and the push rod 426 respectively. The end of the push rod 426 away from the push spring 425 faces the limiting post 422 so that the push rod 426 pushes the laser film close to the limiting post 422.

[0049] It should be noted that the sleeve 424 is a hollow structure with an internal cylindrical shape, and a limiting ring 4241 is provided at one end of the sleeve 424. Further, the end of the sleeve 424 away from the limiting ring 4241 is mounted on a slide block 421, with the sleeve 424 located at one end of the slide block 421. Further, one end of the push rod 426 slides within the sleeve 424, and a retaining ring 4261 is provided on the end of the push rod 426 that slides within the sleeve 424, preventing the push rod 426 from sliding out of the sleeve 424. Further, a push spring 425 is located within the sleeve 424, and the push spring 425 pushes the slide block 421 and the push rod 426 respectively, causing the end of the push rod 426 away from the retaining ring 4261 to move away from the sleeve 424. Furthermore, the abutment wheel 427 is rotatably mounted on the end of the push rod 426 away from the retaining ring 4261, and the push spring 425 pushes the push rod 426 so that the push rod 426 drives the abutment wheel 427 to abut against the laser film.

[0050] like Figures 5 to 7 As shown, in one embodiment, the push rod 426 and the slide 421 have an included angle.

[0051] It should be noted that one end of the slide block 421 is provided with an angled portion 4214, and one end of the sleeve 424 is provided on the angled portion 4214, so that there is an angle between the push rod 426 and the slide block 421. Furthermore, the sleeve 424 is provided on the side of the slide block 421 facing the angled portion, so that the end of the push rod 426 away from the sleeve 424 faces the limiting post 422. Therefore, when the push rod 426 drives the abutment wheel 427 to abut against the laser film, the abutment wheel 427 drives the laser film closer to the limiting post 422. Furthermore, since the two slide blocks 421 are located at both ends of the slide rail 411, the two abutment wheels 427 abut against both ends of the laser film.

[0052] It should be noted that a limiting member 42 is provided with two sleeves 424, two push springs 425, two push rods 426, and two abutment wheels 427. Both ends of the slide block 421 are provided with beveled portions 4214, and the two beveled portions 4214 face each other. Further, the two sleeves 424 are each provided with two beveled portions 4214 facing the limiting post 422, so that the ends of the two sleeves 424 away from the beveled portions 4214 both face the limiting post 422. The two push rods 426 slide within the two sleeves 424, and the two abutment wheels 427 are rotatably mounted on the ends of the two push rods 426 away from the sleeves 424. Because the ends of the two sleeves 424 furthest from the angled portion 4214 are close to each other, the two push rods 426 are at an angle to the limiting post 422. For example, one push rod 426 is downward and close to the limiting post 422, while the other push rod 426 is upward and close to the limiting post 422. This causes the two push rods 426 to drive the two abutting wheels 427 towards the limiting post 422 and abut against each other. Thus, when the laser film passes through the support plate 41, the two abutting wheels 427 on one limiting member 42 abut against the upper and lower surfaces of one end of the laser film, causing the two push springs 425 to push the push rods 426 so that the two push rods 426 drive the two abutting wheels 427 to push the end of the laser film closer to the limiting post 422. Since the two slide blocks 421 are located at both ends of the slide rail 411, the abutment rollers 427 push the two ends of the laser film close to the two limit posts 422, thereby causing the abutment rollers 427 to flatten the laser film at both ends, so that the laser film is smoothly wound onto the take-up roller 20.

[0053] like Figure 8 As shown, in one embodiment, the push rod 426 has a flat portion, and the sleeve 424 has a flat-convex portion, with the flat portion abutting against the flat-convex portion.

[0054] It should be noted that a retaining ring 4261 is provided at one end of the push rod 426, and the outer diameter of the retaining ring 4261 is larger than the diameter of the push rod 426. A limiting ring 4241 is provided at the end of the sleeve 424 away from the slide block 421. The inner diameter of the limiting ring 4241 is smaller than the diameter of the push rod 426, so that the push rod 426 can slide inside the sleeve 424 and cannot slide out of the sleeve 424. Furthermore, a flat portion is formed on the circumferential surface of the push rod 426, extending from one end of the push rod 426 to the retaining ring 4261 at the other end. For example, the push rod 426 has a cylindrical structure, and a cut is made on the circumferential surface in the axial direction, so that a flat surface is formed on the circumferential surface of the push rod 426. A flat-convex portion is provided on the limiting ring 4241, which is adapted to the flat portion. In this way, when the push rod 426 slides inside the sleeve 424, the push rod 426 cannot rotate.

[0055] like Figures 2 to 5 As shown, in one embodiment, the limiting component 40 further includes two balancing members 43, which are respectively disposed on both sides of the support plate 41. Both balancing members 43 are grounded with the laser film, and the two balancing members 43 are used to adjust the angle between the support plate 41 and the surface of the laser film to maintain perpendicularity.

[0056] It should be noted that the two balancing components 43 are respectively disposed on both sides of the support plate 41, and each limiting component 42 is located between the two balancing components 43. Thus, when the laser film passes through the support plate 41, the two balancing components 43 abut against the laser film on both sides of the support plate 41. Since the support plate 41 is rotatably disposed on the frame 30, when the laser film is in an inclined state, the laser film will push against the two balancing components 43 with the circumference of both ends of the support plate 41 as the center, thereby causing the two balancing components 43 to drive the support plate 41 to rotate.

[0057] like Figures 2 to 5 As shown, in one embodiment, the balancing member 43 includes a support roller 431, two support blocks 432 and several support springs 433. The two ends of the support roller 431 are rotatably connected to the two support blocks 432 respectively. The two support blocks 432 are slidably disposed at the two ends of the support plate 41 respectively. Each support spring 433 is sleeved on the support plate 41 and each support block 432 respectively.

[0058] It should be noted that the two push rods 426 respectively drive the two abutment rollers 427 toward the limiting post 422 and bring them closer to each other, so that the two abutment rollers 427 are in contact with each other at the middle position of the limiting post 422. Furthermore, each side of the support plate 41 has a sliding groove 4211 at both ends, and the opening direction of the sliding groove 4211 is consistent with the axial direction of the limiting post 422. The two support blocks 432 are respectively engaged with the two sliding grooves 4211, so that the two support blocks 432 can slide closer to or further away from the middle position of the limiting post 422. Furthermore, a guide post 4321 is provided on the support block 432, and a guide hole is provided on the support plate 41. The guide post 4321 passes through the guide hole, and each support spring 433 is respectively sleeved on the guide post 4321 of each support block 432. Each support spring 433 abuts against the support plate 41 and the support block 432, thereby causing each support spring 433 to push each support block 432 to slide closer to the middle position of the limiting post 422. Furthermore, both ends of the support roller 431 are rotatably connected to the two support blocks 432, so that when the two support blocks 432 approach the middle position of the limiting post 422, the two support blocks 432 simultaneously drive the support roller 431 to abut against the laser film.

[0059] It should be noted that four balancing components 43 are provided, all located on both sides of the support plate 41, with two balancing components 43 on each side of the support plate 41. The two balancing components 43 on one side of the support plate 41 face each other; for example, the support rollers 431 of both balancing components 43 slide towards the center position of the limiting post 422, so that the two support rollers 431 together clamp the laser film. When the take-up roller 20 is winding the laser film, the diameter of the take-up roller 20 gradually increases as more laser film is wound, resulting in a gradual increase in the angle of the laser film relative to the horizontal plane between the take-up roller 20 and the guide roller 10. Thus, when the angle between the laser film and the horizontal plane changes, the support rollers 431 on both sides of the support plate 41 will push the two ends of the laser film respectively, so that the support plate 41 rotates with the change of the angle between the laser film and the horizontal plane, thereby enabling the support plate 41 to remain in a state that is perpendicular to the laser film, so that the abutment rollers 427 on the two limiting members 42 push the laser film closer to the limiting post 422 in a state that is perpendicular to the laser film.

[0060] like Figure 1As shown, in one embodiment, two take-up rollers 20 are provided, each located on one end of the frame 30, with one located at the upper end and the other at the lower end. Further, four guide rollers 10 are provided, each rotatably mounted on the frame 30. For ease of description, the four guide rollers 10 are defined as the first guide roller, the second guide roller, the third guide roller, and the fourth guide roller. The first and second guide rollers are close to each other to clamp the laser film together. The third guide roller is located above the first guide roller, and the distance between the third guide roller and the take-up roller is greater than the distance between the first guide roller and the take-up roller. The distance between the fourth guide roller and the take-up roller is greater than the distance between the second guide roller and the take-up roller. Furthermore, the laser film first passes through the gap between the first guide roller and the second guide roller. The transfer film will wrap around the circumference of the first guide roller to the third guide roller on the rear side and then be folded back, and then wound onto the take-up roller 20 located at the upper end of the frame 30. Meanwhile, the original film will wrap around the circumference of the second guide roller to the fourth guide roller on the rear side and then be folded back, and then wound onto the take-up roller 20 located at the lower end of the frame 30. In this way, the transfer film and the original film that can be separated from the laser film can be wound up separately.
