A feeding guide mechanism for an automatic metal sheet coating machine

Abstract

This application discloses a feeding guide mechanism for an automatic metal sheet coating machine, including side plates, a conveyor belt between the two side plates, a coating machine body fixedly connected to the top of the two side plates, and a fixed frame on each opposite side of the two side plates. Multiple rollers are rotatably connected inside the fixed frame. A lifting assembly is provided on the left end face of the coating machine body. This application utilizes rollers to limit the rolling movement of the metal sheet, preventing the metal sheet from tilting during feeding. Simultaneously, the bidirectional lead screw rotates, causing two moving blocks to drive the two fixed plates to move relative to each other or towards each other. The movement of the fixed plates drives the movement of the limiting rod, which in turn drives the movement of the fixed frame, thereby adjusting the distance between the two fixed frames to accommodate metal sheets of different widths, thus expanding the applicability of the device. Furthermore, the height of the flattening roller is adjustable, facilitating the use of metal sheets of different thicknesses.

Description

Technical Field

[0001] This application relates to the field of metal sheet coating technology, and more specifically, to a feeding guide mechanism for an automatic metal sheet coating machine. Background Technology

[0002] Metal sheet lamination technology is a processing technique that involves bonding a plastic film to a metal sheet through high-temperature hot pressing. Because lamination does not use adhesives or solvents, it is formaldehyde-free. Furthermore, the plastic film can be treated for aesthetics, decoration, antibacterial properties, and stain resistance, ensuring human safety and health while also contributing to environmental protection. Before lamination, the metal sheet needs to be transported to the lamination location. This transportation requires a lamination-coating metal sheet forming and feeding guide mechanism. This mechanism is an automated device that transports and laminates metal sheets. It mainly consists of an installation component and a feeding component, and offers advantages such as convenient transportation, high transportation speed, and large transport capacity.

[0003] In practical use, it has been found that when metal sheets enter the laminating machine for lamination, they often tilt during the feeding process. At the same time, air bubbles will appear during lamination, which will affect the lamination effect and production quality. There are problems with the inability to guide and straighten the metal sheets and avoid air bubbles during lamination, which will affect the lamination effect and production quality.

[0004] To address the aforementioned issues, this application provides a feeding guide mechanism for an automatic metal sheet coating machine. Utility Model Content

[0005] One objective of this application is to provide a feeding guide mechanism for an automatic metal sheet laminating machine, comprising side plates, a conveyor belt disposed between two side plates, a laminating machine body fixedly connected to the top of the two side plates, a fixing frame disposed on each opposite side of the two side plates, multiple rollers rotatably connected inside the fixing frame, a bidirectional lead screw rotatably connected between the two side plates, two moving blocks symmetrically threaded onto the outer side of the bidirectional lead screw, a fixing plate and a limiting rod slidably inserted into the side plates, a connecting block fixedly connected to the top of each of the two fixing frames, a sliding groove formed on the inner surface of the connecting block, a sliding block slidably connected inside the sliding groove, a bracket fixedly connected to each opposite side of the two sliding blocks, a flattening roller rotatably connected to the inner side of the bracket, and a lifting assembly disposed on the left end face of the laminating machine body.

[0006] Furthermore, a sliding hole is provided on the side plate, and the fixing plate is slidably inserted into the sliding hole. The fixing plate is arranged in an "L" shape. One end of the fixing plate is fixedly connected to the limiting rod, and the other end of the fixing plate is fixedly connected to the moving block.

[0007] Furthermore, the side plate is symmetrically provided with sliding holes, and the limiting rod is arranged in a "U" shape. The two ends of the limiting rod are slidably inserted into the sliding holes, and both ends of the limiting rod are fixedly connected to the fixing frame.

[0008] Furthermore, the sliding block is arranged in a cross shape, and the two supports are staggered.

[0009] Furthermore, the lifting assembly includes a support frame and a connecting plate. The connecting plate is fixedly connected to the left end face of the laminating machine body. An electric push rod is fixedly connected to the top of the connecting plate. The output end of the electric push rod passes through the connecting plate and extends to the bottom of the connecting plate. A fixing block is fixedly connected to the output end of the electric push rod. Rectangular slots are provided at both ends of the fixing block. A support frame is slidably inserted into the connecting block.

[0010] Furthermore, the top of the connecting block has a through hole that communicates with the sliding groove, one end of the support frame is slidably inserted into the inside of the through hole, and the other end of the support frame is slidably inserted into the inside of the rectangular groove.

[0011] Furthermore, two fixing rods are fixedly connected between the two side plates, and the two fixing rods are respectively located below both ends of the conveyor belt.

[0012] The beneficial effects of this application are:

[0013] This application utilizes rollers to limit the rolling movement of the metal plate, preventing it from tilting during feeding. Simultaneously, the rotation of the bidirectional lead screw causes two moving blocks to drive two fixed plates to move relative to each other or towards each other. The movement of the fixed plates moves the limiting rod, which in turn moves the fixing frame, thus adjusting the distance between the two fixing frames to accommodate metal plates of different widths, expanding the applicability of the device. Furthermore, the flattening rollers expel air bubbles generated during film coating. Because the two flattening rollers are staggered, they do not separate when moving towards each other, achieving complete air bubble expulsion on film coatings of different widths. The height of the flattening rollers is also adjustable, facilitating the use of metal plates of varying thicknesses. Attached Figure Description

[0025] Example:

[0026] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 This application discloses a feeding guide mechanism for an automatic metal sheet coating machine, including side plates 1, a conveyor belt 3 between the two side plates 1, a coating machine body 6 fixedly connected to the top of the two side plates 1, and a fixed frame 4 on each opposite side of the two side plates 1. Multiple rollers 5 are rotatably connected inside the fixed frame 4. The rollers 5 inside the two fixed frames 4 can limit the rolling movement of the metal sheet on both sides, thereby preventing the metal sheet from tilting during feeding and affecting the coating effect. A bidirectional lead screw 17 is rotatably connected between the side plates 1, and a rotating handle is fixedly connected to the front end of the bidirectional lead screw 17. The rotating handle drives the bidirectional lead screw 17 to rotate, thereby causing two moving blocks 16 to drive the two fixed plates 7 to move relative to each other or towards each other. The movement of the fixed plates 7 drives the movement of the limiting rod 2, and the movement of the limiting rod 2 drives the movement of the fixed frame 4, thereby adjusting the distance between the two fixed frames 4 to accommodate metal sheets of different widths. The applicability of the device is improved. At the same time, when the fixed frame 4 moves, it can drive the connecting block 12 and the bracket 14 to move, thereby driving the flattening roller 15 to move. Since the two flattening rollers 15 are staggered, they will not separate when they move towards each other, thus achieving a complete squeezing effect on the film covering metal plates of different widths. Two moving blocks 16 are symmetrically threaded on the outer side of the bidirectional screw 17. The fixed plate 7 and the limiting rod 2 are slidably inserted on the side plate 1. The top of the two fixed frames 4 are fixedly connected to the connecting block 12. The inner surface of the connecting block 12 is provided with a sliding groove. The sliding block 13 is slidably connected inside the sliding groove. The bracket 14 is fixedly connected to the opposite side of the two sliding blocks 13. The flattening roller 15 is rotatably connected to the inner side of the bracket 14. The left end face of the laminating machine body 6 is provided with a lifting component. The sliding block 13 is arranged in a "+" shape, and the two brackets 14 are staggered.

[0027] Please see Figure 1 and Figure 2The side plate 1 has a sliding hole, and the fixing plate 7 is slidably inserted into the sliding hole. The fixing plate 7 is arranged in an "L" shape. One end of the fixing plate 7 is fixedly connected to the limiting rod 2, and the other end of the fixing plate 7 is fixedly connected to the moving block 16. The side plate 1 has symmetrical sliding holes, and the limiting rod 2 is arranged in a "U" shape. Both ends of the limiting rod 2 are slidably inserted into the sliding hole, and both ends of the limiting rod 2 are fixedly connected to the fixing frame 4.

[0028] Please see Figure 2 The lifting assembly includes a support frame 10 and a connecting plate 9. The connecting plate 9 is fixedly connected to the left end face of the laminating machine body 6. An electric push rod 8 is fixedly connected to the top of the connecting plate 9. The output end of the electric push rod 8 passes through the connecting plate 9 and extends to the bottom of the connecting plate 9. A fixing block 11 is fixedly connected to the output end of the electric push rod 8. Rectangular slots 18 are opened at both ends of the fixing block 11. The support frame 10 is slidably inserted into the connecting block 12. A through hole communicating with the sliding slot is opened at the top of the connecting block 12. One end of the support frame 10 is slidably inserted into the through hole, and the other end of the support frame 10 is slidably inserted into the rectangular slot 18. The electric push rod 8 is controlled to work to drive the fixing block 11 to lift and lower. The lifting and lowering of the fixing block 11 drives the support frame 10, the sliding block 13 and the flattening roller 15 to lift and lower. The sliding block 13 moves inside the sliding slot, thereby driving the bracket 14 to move, which facilitates the height adjustment of the flattening roller 15. This makes it suitable for use with metal plates of different thicknesses and improves the applicability of the device.

[0029] When the two fixed frames 4 move toward each other or relative to each other, the fixed frames 4 drive the connecting block 12 and the support frame 10 to move. The support frame 10 moves inside the rectangular groove 18, which improves the stability of the support frame 10 when it moves.

[0030] Please see Figure 1 Two fixing rods (not shown in the figure) are fixedly connected between the two side plates 1, and the two fixing rods are located below the two ends of the conveyor belt 3 respectively. The two fixing rods play the role of connecting and fixing the two side plates 1 together, thereby improving the stability of the connection between the two side plates 1 and thus improving the stability of the conveyor belt 3.

[0031] The implementation principle of this application embodiment is as follows: When in use, the metal plate is placed on the right end of the conveyor belt 3, and the handle is turned to drive the bidirectional lead screw 17 to rotate, so that the two moving blocks 16 respectively drive the two fixed plates 7 to move relative to each other or towards each other. The movement of the fixed plates 7 drives the limit rod 2 to move, and the movement of the limit rod 2 drives the fixed frame 4 to move, thereby adjusting the distance between the two fixed frames 4 so that the rollers 5 on the inner side of the two fixed frames 4 roll and limit the front and rear sides of the metal plate, thereby preventing the metal plate from tilting during the feeding process. Then, the conveyor belt 3 is controlled to work, so that the metal plate is transported by the conveyor belt 3. When it is transported to the bottom of the laminating machine body 6, the laminating machine body 6 performs the laminating work on the metal plate.

[0032] The electric push rod 8 is controlled to drive the fixed block 11 to rise and fall. The rise and fall of the fixed block 11 drives the support frame 10, the sliding block 13 and the flattening roller 15 to rise and fall. The sliding block 13 moves inside the sliding groove, thereby driving the bracket 14 to move, which facilitates the height adjustment of the flattening roller 15, so that the flattening roller 15 contacts the surface of the film, thereby using the flattening roller 15 to squeeze out the air bubbles generated by the film, avoiding the generation of air bubbles and affecting the production quality.

[0033] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and application concept of this application, should be included within the scope of protection of this application.
