Description

Technical Field

[0001] This utility model relates to the field of coating machine technology, specifically a transfer device. Background Technology

[0002] Coating machines transfer paint onto films and paper. Taking film as an example, during production, the coating roller of the coating machine picks up paint from the paint tank. The film comes into contact with the coating roller, and as the film is pulled along, the coating roller rotates, transferring the paint onto the film. However, during the coating process, the amount of paint picked up by the coating roller cannot be precisely controlled, resulting in excess paint on the roller. When the paint drips back into the paint tank, some paint flows to various parts of the coating roller. Paint flowing to both ends of the coating roller affects its rotation, and the narrow gaps at the ends of the coating roller make cleaning inconvenient, making the maintenance of the coating machine quite troublesome. Utility Model Content

[0003] The purpose of this invention is to provide a transfer device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a transfer device, comprising a frame, on which an applicator roller and an adjuster are rotatably mounted, and a winding roller is rotatably mounted on the adjuster. The winding roller is located above the applicator roller. The adjuster changes the distance between the winding roller and the applicator roller, which can adapt to films of different thicknesses and has good versatility. Both ends of the surfaces of the winding roller and the applicator roller are provided with anti-flow grooves to block the free flow of paint and will not affect the rotation of the applicator roller.

[0005] The receiving box is installed on the frame and located below the coating roller. It can recycle paint. The receiving box is equipped with a holding box. The lower part of the surface of the holding box is connected to an inclined discharge nozzle. The paint in the holding box flows to the surface of the coating roller through the discharge nozzle. The flow rate of the paint can be controlled, thereby avoiding excessive paint on the coating roller. The flow-stop groove intercepts excess paint and guides it to the receiving box, so as not to waste paint and maintain the consistency of product quality.

[0006] A scraper plate is equipped with a push-pull component, which is connected to the frame. The push-pull component adjusts the distance between the scraper plate and the coating roller, which can remove the coating from the coating roller as needed and control the coating thickness.

[0007] Furthermore, the positioner includes a first cylinder and a bearing seat connected to the first cylinder. The first cylinder is mounted on the frame, and both ends of the winding roller are inserted into the bearing seat. Compared with manual adjustment, it improves adjustment efficiency, adapts to the needs of rapid production line changeover or process parameter adjustment, and can achieve precise positioning of the winding roller, ensuring the accuracy of coating thickness and film transmission gap, and improving product quality stability.

[0008] Furthermore, two limiting rails are installed on the frame, and the bearing seat slides between the two limiting rails to prevent the bearing seat from shifting laterally or tilting during movement, thereby ensuring the parallelism between the winding roller and the coating roller and improving the uniformity of the coating thickness.

[0009] Furthermore, the container is equipped with a sealing cover, which has several interface pipes. These interface pipes can be flexibly connected to external paint supply devices, such as a feed pump or a storage tank, to achieve automatic or manual paint supply. Paint can be supplied without opening the sealing cover, reducing operation steps and improving supply efficiency. The lower surface of the receiving box is connected to a recycling pipe to realize the recycling of paint.

[0010] Furthermore, a guide roller is installed inside the frame, located on the left side above the winding roller, to ensure that the film enters the coating area in a stable and smooth manner, avoiding problems such as wrinkles, deviations, and uneven tension of the film. The adjustment method has a high degree of automation and fast response speed, and can quickly adapt to the process requirements of different coating viscosities and coating thicknesses.

[0011] Furthermore, the push-pull component includes a second cylinder and a push-pull rod connected to the second cylinder. The push-pull rod is rotatably mounted on a mounting base. The scraper plate is mounted on the mounting base. A support plate is mounted on the frame. The push-pull rod is located on the upper surface of the support plate.

[0012] Furthermore, the push-pull rod is rotatably connected to a hinge seat, and the mounting seat is fixedly connected to the hinge seat. An adjusting bolt is screwed onto the mounting seat, and the adjusting bolt rests on the surface of the push-pull rod. The scraper plate can move and has redundancy. If there is too much paint on the coating roller, the scraper plate will float and will not excessively affect the rotation of the coating roller.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) The paint is contained in the container and flows onto the application roller through the nozzle. The pressure in the container is different, which can control the flow rate of the nozzle and thus control the amount of paint on the application roller. This prevents excessive paint from flowing over a wide area. Both the application roller and the wrapping roller are equipped with anti-flow grooves to block the free flow of paint and prevent paint from flowing to both ends of the application roller and the wrapping roller. This will not affect the rotation of the application roller and the wrapping roller and reduce the difficulty of maintenance.

[0015] (2) The first cylinder controls the movement of the bearing seat to adjust the height of the winding roller. The limit rail restricts the position of the bearing seat movement to ensure the stability of the winding roller lifting and lowering. The distance between the winding roller and the coating roller can be changed freely according to the thickness of the film to adapt to the coating of films of different thicknesses.

[0016] (3) The second cylinder adjusts the position of the scraper plate by pushing and pulling rod and mounting seat. The distance between the scraper plate and the coating roller is different, which can adjust the amount of coating on the coating roller and control the amount of coating on the film. The scraper plate has a certain swing space. When there is too much coating on the coating roller, scraping off the coating will not affect the stable rotation of the coating roller.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example:

[0025] Please see Figure 1-5This utility model provides a technical solution: a transfer device, including a frame 1, on which an applicator roller 6 and an adjuster are rotatably mounted. A winding roller 3 is rotatably mounted on the adjuster. The winding roller 3 is located above the applicator roller 6. The adjuster changes the distance between the winding roller 3 and the applicator roller 6. Both ends of the surfaces of the winding roller 3 and the applicator roller 6 are provided with anti-flow grooves 4. The film is wrapped in a V-shape around the surface of the winding roller 3, so that the film can stably contact the applicator roller 6. The coating on the applicator roller 6 can be applied to the film. By changing the distance between the winding roller 3 and the applicator roller 6, coating can be stably applied to films of different thicknesses.

[0026] A receiving box 7 is installed on the frame 1 and located below the coating roller 6. The size of the receiving box 7 is larger than that of the coating roller 6. The paint dripping from the coating roller 6 is collected by the receiving box 7. A holding box 5 is installed on the receiving box 7. Two square rods are set between the holding box 5 and the receiving box 7. The lower part of the surface of the holding box 5 is connected to an inclined discharge nozzle 19. The paint in the holding box 5 flows to the surface of the coating roller 6 through the discharge nozzle 19. The discharge nozzle 19 is flat, so that the paint flows evenly to the coating roller 6. The flow-stopping groove 4 intercepts excess paint and guides it to the receiving box 7 to prevent the paint from flowing to both ends of the coating roller 6 and to ensure that the paint does not flow onto the frame 1 and the bearing seat 10, reducing the difficulty of cleaning and maintenance.

[0027] The scraper plate 16 is equipped with a push-pull component, which is connected to the frame 1. The push-pull component adjusts the distance between the scraper plate 16 and the coating roller 6, thereby controlling the amount of paint on the coating roller 6 and the amount of paint applied.

[0028] In this embodiment, as Figure 1 As shown, the adjusting device includes a first cylinder 11 and a bearing seat 10 connected to the first cylinder 11. The first cylinder 11 is mounted on the frame 1. The two ends of the winding roller 3 are inserted into the bearing seat 10. The first cylinder 11 changes the height of the winding roller 3 by controlling the lifting and lowering of the bearing seat 10, thereby changing the distance between the winding roller 3 and the coating roller 6. When the film is thick, the distance can be increased to prevent the film from deforming due to compression and to protect the integrity of the film.

[0029] In this embodiment, as Figure 1 As shown, two limiting rails 9 are installed on the frame 1, and the bearing seat 10 is slidably connected between the two limiting rails 9. The two limiting rails 9 have rectangular grooves, and the bearing seat 10 has corresponding protrusions. The protrusions are connected to the rectangular grooves to improve the accuracy and stability of the lifting of the bearing seat 10 and the roller 3.

[0030] In this embodiment, as Figure 1 and Figure 4As shown, the container 5 is provided with a sealing cover 12, and the sealing cover 12 is provided with a plurality of interface pipes 13. The sealing cover 12 seals the container 5. By connecting the pump and the pipes to the interface pipes 13, the paint can be delivered to the container 5. The lower surface of the receiving box 7 is connected to a recovery pipe 8. The paint in the receiving box 7 can be extracted by using the recovery pipe 8 in conjunction with the pump.

[0031] In this embodiment, as Figure 1 and Figure 2 As shown, a guide roller 2 is installed inside the frame 1. The guide roller 2 is located on the left side above the winding roller 3. The film passes through the guide roller 2, which improves the stability of the film movement, prevents film wrinkles and deviations, and improves the coating accuracy.

[0032] In this embodiment, as Figure 3 As shown, the push-pull component includes a second cylinder 14 and a push-pull rod 17 connected to the second cylinder 14. The push-pull rod 17 is rotatably mounted on a mounting base 20. The scraper plate 16 is mounted on the mounting base 20. A support plate 15 is mounted on the frame 1. The push-pull rod 17 is located on the upper surface of the support plate 15. The second cylinder 14 controls the push-pull rod 17 to move on the support plate 15 to prevent the support plate 15 from sagging. This ensures the stability of the movement of the mounting base 20 and the scraper plate 16, allowing the scraper plate 16 to stably remove excess paint from the coating roller 6.

[0033] In this embodiment, as Figure 3 As shown, the push-pull rod 17 is rotatably connected to the hinge seat 18, and the mounting seat 20 is fixedly connected to the hinge seat 18. An adjusting bolt 21 is screwed onto the mounting seat 20. The adjusting bolt 21 rests on the surface of the push-pull rod 17. Twisting the push-pull rod 17 changes the floating range of the scraper plate 16. The scraper plate 16 and the mounting seat 20 can swing around the hinge seat 18. If there is too much paint on the coating roller 6, the floating of the scraper plate 16 can prevent the rotation resistance of the coating roller 6 from changing suddenly. The mounting seat 20 and the push-pull rod 17 have insertion holes, and the scraper plate 16 can be controlled to float by using the insertion rod.

[0034] Specifically, in use, two pumps are used and connected to the interface pipe 13 and the recovery pipe 8 respectively. After passing through the guide roller 2, the film is wound in a V-shape on the winding roller 3.

[0035] The pump delivers the paint into the container 5. The paint flows through the nozzle 19 onto the surface of the coating roller 6. The coating roller 6 rotates and moves the paint toward the scraper plate 16. The scraper plate 16 makes the paint evenly applied to the surface of the coating roller 6 and scrapes off the excess paint. The excess paint falls into the collection box 7.

[0036] The film contacts the coating roller 6, and the coating roller 6 applies the coating to the film. The film moves as the roller 3 rotates, allowing the coating to be applied to the film continuously.

[0037] The paint picked up on the roller 3 also falls into the receiving box 7. Both the roller 3 and the applicator roller 6 are equipped with anti-flow grooves 4. The paint flows into the anti-flow grooves 4, which can prevent the paint from continuously flowing to both ends of the roller 3 and the applicator roller 6. This will not affect the rotation of the roller 3 and the applicator roller 6, and also eliminates the need for cleaning and maintenance, making coating more convenient.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
