Description

Technical Field

[0001] This utility model relates to the field of hot stamping foil coating technology, specifically to a wear-resistant hot stamping foil film coating device. Background Technology

[0002] Hot stamping foil is a commonly used hot stamping material, mainly used to achieve a metallic texture or special gloss decorative effect on the surface of the substrate. Wear-resistant hot stamping foil, on the other hand, is an improved version of hot stamping foil with enhanced wear resistance to increase its service life.

[0003] Currently, when hot stamping foil is coated with film, there are several coating methods, including slot coating, micro-gravure coating, comma blade coating, and gravure coating. Regardless of the coating method, the film needs to be transported by the corresponding conveyor and conveyor rollers. The flatness of the film during conveyor roller transport directly affects the coating effect. However, current film coating equipment generally only has a correction device to check whether the edge position of the film is correct. When the film near the coating position is uneven, it cannot be smoothed, resulting in poor coating. Utility Model Content

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0005] A wear-resistant hot stamping foil film coating device includes a machine body. A support roller is installed at the middle position of the front side of the machine body. Traction rollers are installed on the upper and lower positions of the machine body behind the support roller. Hot stamping foil body is wound on the traction roller and the support roller. A leveling rod is installed on the rear side of the machine body near the traction roller. A long shaft is installed on the rear side of the leveling rod. Multiple short rollers with equal spacing are fixed on the long shaft. The short rollers abut against the inner side of the hot stamping foil body at the corresponding position.

[0006] Furthermore, support frames are fixed at the bottom of both ends of the leveling rod. The support frames are fixed to the machine body at the corresponding positions. A motor is fixed at one end of the long shaft on the support frame, and the output end of the motor is fixedly connected to the long shaft at the corresponding position. The motor is a stepper motor, which can easily control the rotation of the guide roller.

[0007] Furthermore, the flattening rod is configured in a ">" shape, with the middle protruding backward and both ends extending forward. The short roller on the flattening rod near the bottom of the machine body rotates counterclockwise, while the short roller on the flattening rod near the top of the machine body rotates clockwise. The rearward protrusion in the middle and the forward extension at both ends conform to the path of the hot stamping foil body being pulled in from the bottom and pulled out from the top.

[0008] Furthermore, a tensioning roller is installed between the support roller and the traction roller below the rear side. The hot stamping foil body wraps around the outside of the traction roller and the support roller, and the tensioning roller abuts against the outside of the hot stamping foil body. A slit coating die is installed on the front side of the machine body corresponding to the position of the support roller, with the extrusion end of the slit coating die positioned close to the hot stamping foil body. The tensioning roller can adjust the tension of the hot stamping foil body. The slit coating die corresponds to the existing slit coating method. Of course, the slit coating die can also be replaced with a die used for other coating methods.

[0009] Furthermore, frames are fixed to both ends of the support roller, traction roller, and tension roller on the inner side of the machine body. Shaft seats are installed on the frames corresponding to the support roller and traction roller positions. The ends of the support roller and traction roller are mounted to the corresponding shaft seats. Elongated holes are formed on the frames corresponding to the ends of the tension roller. Bearings are installed at both ends of the tension roller at the elongated holes. Sleeves are installed on the frames corresponding to the bearing positions, forming a sleeve connection. End plates are fixed to both ends of the frames near the sleeves. Springs are installed between the end plates and the corresponding sleeves, with both ends of the springs fixed to the end plates and sleeves. The tension of the tension roller is adjusted adaptively by the springs according to the tension of the hot stamping foil body.

[0010] Furthermore, a scraper is installed above the slit coating die head near the hot stamping foil body. This scraper can remove excess coating material from the surface of the hot stamping foil body.

[0011] Furthermore, a transfer roller is installed below the front side of the scraper, close to the scraper. Support seats are fixed to the machine body at both ends of the transfer roller, and the two ends of the transfer roller are installed with corresponding support seats. A second motor is installed on the machine body above one end of the transfer roller. Pulleys are installed on the output end of the second motor and on the corresponding transfer roller, and belts are installed on the pulleys of the second motor and the transfer roller. A waste glue tray is installed on the slit coating die head below the transfer roller. The transfer roller can clean the surface of the scraper.

[0012] Furthermore, a scraper is fixed to the top of the waste glue tray near the front of the transfer roller. Multiple equally spaced fixing brackets are fixed to the top of the scraper, and the top of each bracket is fixed to a corresponding scraper. The scraper cleans the surface of the transfer roller, working in conjunction with the transfer roller's cleaning action on the scraper to create a mutual cleaning effect.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model sets up a smoothing rod and uses a rotating short roller to actively contact the surface of the hot stamping foil body. The rotation of the short roller actively smooths the surface of the hot stamping foil body, smoothing out any unevenness on the surface of the hot stamping foil body to be coated, thus ensuring the coating effect.

[0015] 2. In this utility model, the middle of the smoothing rod protrudes backward and the two ends extend forward, which matches the path setting of the hot stamping foil body being pulled in from the bottom and pulled out from the top. Combined with the active rotation effect of the short roller, it can comprehensively ensure the smoothing, stability and reliability of the hot stamping foil body.

[0016] 3. In this utility model, by setting a tension roller and cooperating with the spring, the tension of the hot stamping foil body can be adjusted adaptively, avoiding the hot stamping foil body from being too tight or too loose.

[0017] 4. The present invention includes a scraper, a transfer roller and a scraper plate, which can scrape off excess coating material from the surface of the hot stamping foil body and finally send it into the waste glue tray, thereby ensuring uniform coating. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0026] This application provides a wear-resistant hot stamping foil film coating device, mainly solving the problems of uneven film and lack of smoothing ability during coating, and provides the following technical solution, which will be combined with the following... Figures 1-6 Please provide a detailed explanation:

[0027] A wear-resistant hot stamping foil film coating device includes a machine body 1. A support roller 3 is installed at the middle position of the front side of the machine body 1. Traction rollers 4 are installed on the upper and lower positions of the machine body 1 behind the support roller 3. A tension roller 5 is installed between the support roller 3 and the lower rear traction roller 4. A hot stamping foil body 27 is wound around the traction roller 4, tension roller 5 and support roller 3. The hot stamping foil body 27 is wound to the outside of the traction roller 4 and support roller 3. The tension roller 5 abuts against the outside of the hot stamping foil body 27. A slit coating die head 6 is installed on the front side of the machine body 1 corresponding to the position of the support roller 3. The extrusion end of the slit coating die head 6 is set close to the hot stamping foil body 27.

[0028] A leveling rod 7 is installed on the rear side of the machine body 1 near the traction roller 4. A long shaft 8 is installed on the rear side of the leveling rod 7. Multiple short rollers 9 are fixed on the long shaft 8 at equal intervals. The short rollers 9 abut against the inner side of the hot stamping foil body 27 at the corresponding position. A support frame 11 is fixed at the bottom of both ends of the leveling rod 7. The support frame 11 is fixed to the machine body 1 at the corresponding position. A motor 10 is fixed on the support frame 11 at one end of the long shaft 8. The output end of the motor 10 is fixedly connected to the long shaft 8 at the corresponding position.

[0029] Before use, connect the slit coating die 6 to the existing slit extruder. The material to be coated is extruded by the slit extruder. During use, the hot stamping foil body 27 is first manually pulled and wound around the traction roller 4, support roller 3 and tension roller 5. Then, the existing film traction equipment or the traction roller 4 is equipped with power to pull the hot stamping foil body 27. The traction is bottom in and top out. At the same time as the traction, the slit extruder works and extrudes the material to be coated through the slit coating die 6. By using the close proximity of the slit coating die 6 and the hot stamping foil body 27, and combined with the continuous traction of the hot stamping foil body 27, the coating material is coated on the surface of the hot stamping foil body 27.

[0030] During traction, the motor 10 works synchronously to drive the long shaft 8 to rotate. Utilizing the fixed relationship between the long shaft 8 and the short rollers 9, all the short rollers 9 are driven to rotate. Since the short rollers 9 are in contact with the surface of the hot stamping foil body 27, the rotation of the short rollers 9 can actively smooth the uneven surface of the hot stamping foil body 27, making its surface flat. This ensures that the surface remains flat when passing through the slit coating die head 6, thereby ensuring the coating effect.

[0031] In some embodiments, the flat bar 7 is configured with a ">" shaped structure that bulges backward in the middle and extends forward at both ends.

[0032] With a central convex shape and two forward-extending ends, the structure corresponds exactly to the traction direction of the hot stamping foil body 27. When the hot stamping foil body 27 is pulled in, the central convex shape forms a sharp end, and the two forward-extending ends form a guide from the center to both sides. With the counterclockwise rotation of the short roller 9, the uneven surface of the hot stamping foil body 27 can be smoothed outward in an orderly manner. When the hot stamping foil body 27 is pulled out, since it was previously in a flat state, the clockwise rotation of the short roller 9 above can maintain the flatness of the surface of the hot stamping foil body 27.

[0033] In some embodiments, a frame 2 is fixed at both ends of the support roller 3, traction roller 4 and tension roller 5 on the inner side of the machine body 1. A bearing seat 21 is installed on the frame 2 at the positions corresponding to the support roller 3 and traction roller 4. The two ends of the support roller 3 and traction roller 4 are installed with the bearing seat 21 at the corresponding positions. An elongated hole 22 is opened at both ends of the tension roller 5 on the frame 2. Bearings 26 are installed at both ends of the tension roller 5 at the positions of the elongated hole 22. A sleeve 23 is installed on the frame 2 at the position corresponding to the bearing 26. The sleeve 23 is sleeved on the outside of the bearing 26 to form a sleeve installation. An end plate 24 is fixed at both ends of the frame 2 near the sleeve 23. A spring 25 is installed between the end plate 24 and the sleeve 23 at the corresponding positions. The two ends of the spring 25 are fixed with the end plate 24 and the sleeve 23 at the corresponding positions.

[0034] The tension roller 5 is used to adjust the tension of the hot stamping foil body 27 to avoid excessive tension causing stretching deformation or tearing, and excessive looseness causing wrinkles and unsatisfactory coating effect. During adjustment, the spring 25 adaptively pushes the bearing 26 to move within the range of the elongated hole 22 according to the tension of the hot stamping foil body 27, thereby adaptively adjusting the tension. Since the hot stamping foil body 27 adopts bottom entry and top exit, the tension roller 5 is only set at the bottom position where the hot stamping foil body 27 is pulled in, while the top position is not set because the surface is coated with material.

[0035] In some embodiments, a scraper 12 is installed above the slit coating die head 6 near the hot stamping foil body 27. The scraper 12 can scrape off excess or thick coating material from the surface of the hot stamping foil body 27, thereby making the coating thickness on the surface of the hot stamping foil body 27 uniform.

[0036] In some embodiments, a transfer roller 13 is installed below the front side of the scraper 12. The transfer roller 13 is positioned close to the scraper 12. Support seats 14 are fixed on the machine body 1 at both ends of the transfer roller 13. The two ends of the transfer roller 13 are installed with the support seats 14 at the corresponding positions. A motor 20 is installed on the machine body 1 above one end of the transfer roller 13. Pulleys 18 are installed on the output end of the motor 20 and on the transfer roller 13 at the corresponding position. Belts 19 are installed on the motor 20 and the pulleys 18 of the transfer roller 13. A waste glue tray 15 is installed on the slit coating die head 6 below the transfer roller 13.

[0037] When the scraper 12 scrapes off excess coating material from the surface of the hot stamping foil body 27, the motor 20 works synchronously, using the belt 19 to drive the transfer roller 13 to rotate. When the coating material scraped off by the scraper 12 gradually accumulates on its own surface and is released from the transfer roller 13, the rotation of the transfer roller 13 can rotate the coating material off the scraper 12 and make it fall into the waste glue tray 15 below, thus achieving continuous cleaning of the scraper 12.

[0038] In some embodiments, a scraper 16 is fixed at the top of the waste glue tray 15 near the front side of the transfer roller 13, and a plurality of equally spaced fixing brackets 17 are fixed at the top of the scraper 16, with the top of the fixing brackets 17 fixed to the corresponding scraper 12.

[0039] The scraper 16 can scrape off the coating material on the transfer roller 13, so that it falls into the waste glue tray 15 below, thereby cleaning the surface of the transfer roller 13 and enabling the transfer roller 13 to stably and continuously clean the scraper 12.

[0040] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
