Description

Technical Field

[0001] This utility model belongs to the technical field of composite film processing and transportation devices, and more specifically relates to a high-barrier anti-counterfeiting composite film processing and transportation device. Background Technology

[0002] Anti-counterfeiting is a crucial issue in the trade of goods. Today, anti-counterfeiting measures are necessary in many fields, such as bank cards, checks, securities, various cards, and product codes. However, anti-counterfeiting measures not only require legal intervention but also, to better maintain social order, must address counterfeiting techniques to curb such activities at their source. With the development of the commodity economy and technology, laser anti-counterfeiting technology has been widely used in the circulation of various commodities.

[0003] The most widely used laser high-barrier anti-counterfeiting composite film currently is made by using embossed laser holography technology to create a metal master of the three-dimensional information (i.e., crisscrossing interference fringes) on the surface of a holographic image, and then transferring it to a plastic film through embossing.

[0004] During the processing and transportation of high-barrier anti-counterfeiting composite films, a winding device is required to wind the films. Existing film transport devices are prone to trajectory deviations due to factors such as tension fluctuations when transporting films to the winding device. Since laser-coated high-barrier anti-counterfeiting composite films typically require high-precision holographic patterns or barrier layer structures, winding deviations during winding may cause pattern stretching and deformation, and damage to the barrier layer, directly affecting anti-counterfeiting performance and product quality. Utility Model Content

[0005] To solve the above problems and overcome the shortcomings of the existing technology, this utility model provides a high-barrier anti-counterfeiting composite film processing and transportation device; The first technical problem to be solved was the issue of pattern stretching and deformation caused by winding offset, and damage to the barrier layer, which affected anti-counterfeiting performance and product quality.

[0006] The specific technical solution of this utility model to solve the above-mentioned technical problems is as follows: A high-barrier anti-counterfeiting composite film processing and transportation device includes a frame, and a conveying roller, a guide roller and a curling roller are rotatably arranged on the top of the frame. The guide roller is slidably connected to the frame via a correction guide structure, which includes a guide bearing seat, a transverse slide rail, and an adjustment component. The guide bearing seats are disposed on both sides of the guide roller and are rotatably connected to the guide roller; The transverse slide rail is fixedly installed on the upper end face of the frame and located below the guide bearing seat. The bottom of the guide bearing seat is provided with a transverse slide groove, and the transverse slide rail slides in cooperation with the transverse slide groove. The adjustment assembly includes an adjustment seat, a two-way lead screw, and a handwheel. There are two adjustment seats, which are respectively fixedly installed on the upper end of the guide bearing seat. One end of the two-way lead screw passes through the two adjustment seats and is threadedly connected to the adjustment seats. The other end of the two-way lead screw is fixedly connected to the handwheel.

[0007] Furthermore, the transverse slide rail has a flange, the shape of the transverse slide groove is adapted to the transverse slide rail, and the flange is embedded in the transverse slide groove to form a bidirectional limiting.

[0008] Furthermore, the adjusting seat and the guide bearing seat are fixedly connected by bolts.

[0009] Furthermore, the outer circumferential surface of the handwheel is provided with anti-slip texture.

[0010] Furthermore, the transverse slide rail is made of wear-resistant stainless steel.

[0011] The beneficial effects of this utility model are: One advantage of this invention is the setting of a correction and guidance structure. Rotating the handwheel drives the bidirectional lead screw to rotate, causing the two adjusting seats to move synchronously with the guide bearing seats and guide rollers, thereby adjusting the position of the guide rollers. This effectively corrects the deviation during the conveying process of the high-barrier anti-counterfeiting composite film and improves the flatness and quality of the winding.

Therefore, they should not be construed as limiting the scope of protection of this utility model. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0014] The specific embodiment of this utility model is as follows: A high-barrier anti-counterfeiting composite film processing and transportation device includes a frame 1. A conveying roller 2, a guide roller 3, and a curling roller 4 are sequentially rotatably arranged above the frame 1 along the movement direction of the high-barrier anti-counterfeiting composite film. The conveying roller 2, the guide roller 3, and the curling roller 4 are all made of stainless steel with smooth surfaces to avoid scratching the high-barrier anti-counterfeiting composite film.

[0015] As a preferred embodiment of this utility model The guide roller 3 is slidably connected to the frame 1 via the correction guide structure 5, which includes a guide bearing seat 51, a transverse slide rail 52, and an adjustment component. Two guide bearing seats 51 are provided, respectively located at both ends of the guide roller 3. The guide bearing seats 51 and the guide roller 3 are rotatably connected by deep groove ball bearings, which ensure the flexibility of the guide roller 3's rotation. The guide bearing seats 51 are made of cast steel, which has high strength.

[0016] The transverse slide rail 52 is fixed to the upper end face of the frame 1 by bolts and is located below the guide bearing seat 51. The transverse slide rail 52 is made of wear-resistant stainless steel, which improves its wear resistance and service life. The bottom of the guide bearing seat 51 is provided with a transverse sliding groove 511, and the transverse slide rail 52 slides in cooperation with the transverse sliding groove 511. The transverse slide rail 52 has a flange, and the shape of the transverse sliding groove 511 is adapted to the transverse slide rail 52. The flange is embedded in the transverse sliding groove 511 to form a bidirectional limiting. The fitting clearance between the flange of the transverse slide rail 52 and the transverse sliding groove 511 is 0.1-0.3mm. Preferably, the fitting clearance is 0.2mm, which ensures both smooth sliding and stability during sliding.

[0017] The adjustment assembly includes an adjustment seat 53, a bidirectional lead screw 54, and a handwheel 55. Two adjustment seats 53 are provided and fixedly mounted on the upper end of the guide bearing seat 51, respectively. The adjustment seats 53 and the guide bearing seat 51 are fixedly connected by bolts. One end of the bidirectional lead screw 54 passes through both adjustment seats 53 and is threadedly connected to them. The threads connecting the bidirectional lead screw 54 and the two adjustment seats 53 are in opposite directions, so that when the bidirectional lead screw 54 is rotated, the two adjustment seats 53 can drive the guide bearing seat 51 to move synchronously in opposite directions.

[0018] The other end of the bidirectional lead screw 54 is fixedly connected to the handwheel 55; the outer circumferential surface of the handwheel 55 is provided with anti-slip texture to facilitate the operator's rotation.

[0019] Preferably, the ratio of the center distance between the conveying roller 2 and the guide roller 3 to the center distance between the guide roller 3 and the curling roller 4 is 1:1.5.

[0020] It should be noted that this utility model is a high-barrier anti-counterfeiting composite film processing and transportation device. In specific operation... During operation, the high-barrier anti-counterfeiting composite film is conveyed to the guide roller 3 via the conveyor roller 2, and then wound up by the winding roller 4.

[0021] During the conveying process, the high-barrier anti-counterfeiting composite film is not completely suspended, but forms a certain wrap angle with the surface of the guide roller 3. This contact generates static friction between the high-barrier anti-counterfeiting composite film and the roller surface, ensuring that the high-barrier anti-counterfeiting composite film moves synchronously with the direction of movement of the guide roller 3. When the high-barrier anti-counterfeiting composite film deviates, the operator turns the handwheel 55, which drives the bidirectional lead screw 54 to rotate. The two adjusting seats 53 drive the guide bearing seat 51 to slide along the transverse slide rail 52, thereby driving the guide roller 3 to move left and right.

[0022] At this time, the correction guide structure 5 can finely adjust the position of the guide roller 3 through the adjustment of the transverse slide rail 52. When the guide roller 3 moves laterally, the high-barrier anti-counterfeiting composite film will be pushed or pulled in the area of ​​contact with the roller surface, forming a lateral force along the width direction. This lateral force will exert a continuous constraint force on the continuously conveyed high-barrier anti-counterfeiting composite film, so that the high-barrier anti-counterfeiting composite film will be slightly corrected in each contact with the guide roller 3, and finally accumulate to form the return of the overall trajectory. This structure can effectively correct the deviation of the high-barrier anti-counterfeiting composite film during the conveying process, ensure that the high-barrier anti-counterfeiting composite film always runs smoothly along the preset trajectory, thereby improving the winding quality and solving the problems of pattern stretching deformation and barrier layer damage caused by winding deviation, which affect anti-counterfeiting performance and product quality.
