Description

Technical Field

[0001] This application relates to the field of high-speed paper mounting machine technology, and in particular to a feeding device for a high-speed paper mounting machine. Background Technology

[0002] High-speed laminating machines are mainly used for high-precision bonding of printed face paper with corrugated paper and other materials, and are widely used in the processing of paper products such as books and packaging boxes. With the increasing market demand for paper products, high-speed laminating machines have been widely used in cardboard printing and processing due to their ability to significantly improve the bonding efficiency of face and back papers, greatly promoting the development of the industry.

[0003] In the existing technology, traditional high-speed paper laminating machines have at least the following shortcomings in the feeding process: During the feeding process of corrugated paper, it is difficult to ensure that the corrugated paper is always in a flat state. If the corrugated paper has wrinkles or warps, it will cause uneven contact surfaces when it is subsequently laminated with the face paper, resulting in defects such as air bubbles and misalignment, which seriously affects the quality of the finished product. Furthermore, some high-speed paper laminating machines cannot achieve simultaneous flattening and feeding of corrugated paper during the feeding process, and the step-by-step operation of the process further reduces production efficiency.

[0004] Therefore, we propose a high-speed paper mounting machine feeding device to solve the above problems. Utility Model Content

[0005] The purpose of this application is to provide a feeding device for a high-speed paper laminating machine, which can simultaneously flatten and convey corrugated paper, ensuring that the corrugated paper enters the high-speed paper laminating machine in a flat state, thereby improving the quality of the finished product.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution: a feeding device for a high-speed laminating machine, comprising a feeding box installed and fixed at the paper inlet end of the high-speed laminating machine, wherein the top and left side of the feeding box are open, and several corrugated sheets are stacked on the bottom inner wall of the feeding box, with the right side of the corrugated sheets adhering to the right inner wall of the feeding box.

The lower conveying roller is rotatably mounted on the feeding box. Inside the box on the left side, an L-shaped frame is fixedly installed on the top of the feeding box. The transfer assembly is set on the L-shaped frame, and a cross-shaped plate is set on the transfer assembly. Four electric suction cups are fixedly installed on the bottom of the cross-shaped plate and are evenly distributed. A fixed base is fixedly installed on the bottom left side of the L-shaped frame.

The output shaft ends of the two motors II are fixedly connected to the front end of the upper conveying roller and the front end of the lower conveying roller, respectively.

[0008] A further configuration of this application is as follows: the transfer assembly includes a motor, a lead screw, a movable seat, and an electric telescopic rod.

[0014] A further feature of this application is that the two motors are of the same model and have the same rotation speed, and the two motors rotate in opposite directions.

[0015] By adopting the above technical solution, it is ensured that the lower conveyor roller and the upper conveyor roller rotate synchronously relative to each other.

[0016] A further configuration of this application is as follows: the feeding mechanism further includes a flattening assembly, which includes three lower flattening rollers, two support plates, and three upper flattening rollers. The three lower flattening rollers are rotatably installed in the feeding box and are evenly distributed, and the three lower flattening rollers are all located to the right of the lower conveying roller. The two support plates are fixedly installed on the right side wall of the U-shaped plate. The three upper flattening rollers are rotatably installed between the two support plates and are evenly distributed, and the three upper flattening rollers are respectively located directly above the corresponding lower flattening rollers.

[0017] By adopting the above technical solution, the wrinkles and warping of corrugated paper can be effectively eliminated through the synergistic action of three lower pressure rollers and three upper pressure rollers, ensuring that the corrugated paper enters the high-speed laminating machine in a flat state.

[0020] A further feature of this application is that the outer surfaces of the three lower flat rollers and the three upper flat rollers are all smooth, and the outer surfaces of the lower conveyor rollers and the upper conveyor rollers are provided with anti-slip textures.

[0021] By adopting the above technical solutions, the smooth surface design can improve the leveling effect of corrugated paper, and the anti-slip texture design can enhance the stability of corrugated paper during transportation.

[0022] A further provision of this application is that a positioning roller located to the right of the lower pressure roller is rotatably installed inside the feeding box, the top of the positioning roller being flush with the top of the lower pressure roller, and the positioning roller being located to the left of the corrugated paper.

[0025] By adopting the above technical solution, the linear movement of the limiting plate can be controlled by the electric telescopic rod three. Under the synergistic effect of the two limiting plates, the displacement and scattering of the stacked corrugated paper can be avoided.

[0026] This application includes at least one of the following beneficial technical effects:

[0027] 1. This application utilizes a feeding mechanism that enables the flattening and conveying of corrugated paper to be carried out simultaneously, ensuring that the corrugated paper enters the high-speed laminating machine in a flat state. During the subsequent lamination of the corrugated paper with the face paper, it ensures that the contact surface is flat, reduces defects such as bubbles and misalignment, and improves the quality of the finished product.

[0028] 2. This application utilizes a positioning roller to accurately position the corrugated paper during transfer. When the corrugated paper is transferred using the transfer assembly, the lower surface of the corrugated paper contacts the positioning roller, ensuring that the corrugated paper can pass precisely and smoothly between the lower and upper pressure rollers, and then between the lower and upper conveyor rollers.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0036] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This application provides a feeding device for a high-speed laminating machine, including a feeding box 1 installed and fixed at the paper inlet end of the high-speed laminating machine. The top and left side of the feeding box 1 are open. Several corrugated sheets 2 are stacked on the bottom inner wall of the feeding box 1. The right side of the corrugated sheets 2 is attached to the right inner wall of the feeding box 1. The feeding box 1 is provided with a feeding mechanism, which is used to transport the corrugated sheets 2 one by one to the paper inlet end of the high-speed laminating machine. The feeding mechanism includes a lower conveying roller 3, an L-shaped frame 4, a transfer assembly, a cross-shaped plate 10, four electric suction cups 11, a fixed base 14, an electric telescopic rod 15, a U-shaped plate 16, an upper conveying roller 17, and two motors 18. The lower conveying roller 3 is rotatably installed inside the left side of the feeding box 1. The L-shaped frame 4 is fixedly installed on the top of the feeding box 1. The transfer assembly is set on the L-shaped frame 4. The cross-shaped plate 10 is set on the transfer assembly. The four electric suction cups All four electric suction cups 11 are fixedly installed at the bottom of the cross-shaped plate 10 and are evenly distributed. With the synergistic action of the four electric suction cups 11, the uppermost corrugated paper 2 can be firmly adsorbed and fixed. The fixing seat 14 is fixedly installed at the bottom left side of the L-shaped frame 4. The electric telescopic rod 15 is fixedly installed at the bottom of the fixing seat 14. The U-shaped plate 16 is fixedly installed at the output shaft end of the electric telescopic rod 15. The upper conveying roller 17 is rotatably installed inside the U-shaped plate 16. The upper conveying roller 17 is located directly above the lower conveying roller 3. The two motors 18 are fixedly installed on the front outer wall of the feeding box 1 and the front outer wall of the U-shaped plate 16, respectively. The output shaft ends of the two motors 18 are fixedly connected to the front end of the upper conveying roller 17 and the front end of the lower conveying roller 3, respectively. The electric telescopic rod 15 is used to adjust the height of the U-shaped plate 16 and the upper conveying roller 17, thus making it suitable for conveying and feeding corrugated paper 2 of different thicknesses.

[0037] In this embodiment, the transfer assembly is used to control the raising and horizontal linear movement of the corrugated paper 2, which is adsorbed and fixed at the bottom of the electric suction cup 11, and to transfer it between the downward conveying roller 3 and the upper conveying roller 17. The transfer assembly includes a motor 5, a lead screw 6, a movable seat 7, and an electric telescopic rod 9. The motor 5 is fixedly installed on the top of the L-shaped frame 4, the lead screw 6 is fixedly installed on the output shaft end of the motor 5, the movable seat 7 is threaded onto the lead screw 6, the top of the L-shaped frame 4 has a rectangular hole 8 located to the left of the motor 5, the bottom of the movable seat 7 passes through the rectangular hole 8, and the electric telescopic rod 9 is fixedly installed on the bottom of the movable seat 7. The cross-shaped plate 10 is fixedly installed on the output shaft end of the electric telescopic rod 9. The motor 5 is used to control the rotation of the lead screw 6. The movable seat 7 is threadedly connected to the lead screw 6. During the rotation of the lead screw 6, the movable seat 7 can be controlled to move horizontally and linearly within the rectangular hole 8, thereby driving the electric telescopic rod 9, the cross-shaped plate 10, the four electric suction cups 11, and the corrugated paper 2 that has been adsorbed and fixed to move horizontally and linearly. The height position of the cross-shaped plate 10, the four electric suction cups 11, and the corrugated paper 2 that has been adsorbed and fixed to be adjusted using the electric telescopic rod 9. The motor 5 is a reversible motor.

[0038] In this embodiment, a horizontal guide plate 12 is fixedly installed inside the rectangular hole 8, and the movable seat 7 is slidably sleeved on the horizontal guide plate 12 to enhance the stability of the movable seat 7 when it moves horizontally.

[0039] In this embodiment, a bearing seat 13 located on the left side of the rectangular hole 8 is fixedly installed on the top of the L-shaped frame 4, and the left end of the lead screw 6 is rotatably connected to the bearing seat 13 to enhance the stability of the lead screw 6 when rotating.

[0040] In this embodiment, the two motors 18 are of the same model and have the same speed, and the two motors 18 rotate in opposite directions to ensure that the lower conveyor roller 3 and the upper conveyor roller 17 rotate synchronously relative to each other, so as to stably convey the corrugated paper 2 into the high-speed mounting machine.

[0041] In this embodiment, the feeding mechanism also includes a flattening assembly, which includes three lower flattening rollers 19, two support plates 20, and three upper flattening rollers 21. The three lower flattening rollers 19 are rotatably installed in the feeding box 1 and are evenly distributed, and the three lower flattening rollers 19 are all located to the right of the lower conveying roller 3. The two support plates 20 are fixedly installed on the right side wall of the U-shaped plate 16. The three upper flattening rollers 21 are rotatably installed between the two support plates 20 and are evenly distributed, and the three upper flattening rollers 21 are respectively located directly above the corresponding lower flattening rollers 19. During the feeding of the corrugated paper 2, under the synergistic action of the three lower flattening rollers 19 and the three upper flattening rollers 21, the wrinkles and warping of the corrugated paper 2 are effectively eliminated, ensuring that the corrugated paper 2 enters the high-speed laminating machine in a flat state, ensuring that the contact surface of the corrugated paper 2 and the face paper are flat during the subsequent process, reducing defects such as bubbles and misalignment, and improving the quality of the finished product.

[0042] In this embodiment, the tops of the three lower pressing rollers 19 are flush with the top of the lower conveying roller 3, and the bottoms of the three upper pressing rollers 21 are flush with the bottom of the upper conveying roller 17, ensuring that the conveying and pressing of the corrugated paper 2 are carried out simultaneously and effectively.

[0043] In this embodiment, the outer surfaces of the three lower flat rollers 19 and the three upper flat rollers 21 are all smooth, which improves the leveling effect on the corrugated paper 2. The outer surfaces of the lower conveyor roller 3 and the upper conveyor roller 17 are provided with anti-slip textures to enhance the stability of the corrugated paper 2 during conveying.

[0044] In this embodiment, a positioning roller 22 is rotatably installed inside the feeding box 1, located to the right of the lower pressure roller 19. The top of the positioning roller 22 is flush with the top of the lower pressure roller 19. The positioning roller 22 is located to the left of the corrugated paper 2. The design of the positioning roller 22 can accurately position the transfer position of the corrugated paper 2. When the corrugated paper 2 is transferred using the transfer component, when the lower surface of the corrugated paper 2 contacts the positioning roller 22, it can be ensured that the corrugated paper 2 can accurately and smoothly pass between the lower pressure roller 19 and the upper pressure roller 21, and then pass between the lower conveying roller 3 and the upper conveying roller 17.

[0045] In this embodiment, electric telescopic rods 23 are fixedly installed on the front and rear inner walls of the feeding box 1. Limiting plates 24 are fixedly installed on the output shaft ends of the two electric telescopic rods 23. The two limiting plates 24 are respectively attached to the front and rear sides of the corrugated paper 2. An assembly frame 25 is fixedly installed at the bottom of the feeding box 1. The electric telescopic rods 23 can control the linear movement of the limiting plates 24. Under the synergistic action of the two limiting plates 24, the stacked corrugated paper 2 can be prevented from shifting or scattering, so as to facilitate the feeding of corrugated paper 2 sheet by sheet. The design of the assembly frame 25 is to facilitate the use of bolts or other locking parts to firmly install the feeding box 1 at the paper inlet end of the high-speed paper mounting machine.

[0046] In this embodiment, the wiring connection method and control method of motor 1 5, electric telescopic rod 1 9, electric suction cup 11, electric telescopic rod 2 15, motor 2 18 and electric telescopic rod 3 23 are mature technologies in this field and have been fully disclosed, so they will not be described in detail here.

[0047] With the above structure, the working principle of the high-speed paper mounting machine feeding device provided in this application is as follows:

[0048] Place several stacked corrugated sheets 2 into the feeding box 1, with its right side against the inner right side wall of the feeding box 1. By controlling the extension of two electric telescopic rods 23, the corresponding limit plates 24 can be driven to move linearly. When the two limit plates 24 are against the front and rear sides of the corrugated sheets 2, the operation of the two electric telescopic rods 23 is stopped, which can prevent the stacked corrugated sheets 2 from shifting or scattering and ensure the stability of the paper picking position.

[0049] When feeding corrugated paper 2 sheet by sheet, firstly, control the extension or retraction of the electric telescopic rod 15 to control the vertical movement of the U-shaped plate 16, upper conveyor roller 17, two support plates 20, and three upper pressure rollers 21. This allows adjustment of the distance between the upper conveyor roller 17 and the lower conveyor roller 3. After adjusting the distance between the upper conveyor roller 17 and the lower conveyor roller 3 according to the thickness of the corrugated paper 2, stop the operation of the electric telescopic rod 15. Then, control the rotation of the two motors 18, which drive the lower conveyor roller 3 and the upper conveyor roller 17 to rotate respectively. Control the first motor 5 to rotate forward, and the output shaft of the first motor 5 drives the lead screw 6 to rotate forward. The rotating mechanism causes the movable seat 7 to move horizontally to the right along the horizontal guide plate 12 within the rectangular hole 8. The electric telescopic rod 9, the cross-shaped plate 10, and the four electric suction cups 11 follow suit, moving to the left. When the movable seat 7 reaches the far right, the motor 5 stops. At this point, the four electric suction cups 11 are positioned directly above the stacked corrugated paper 2. Next, the electric telescopic rod 9 extends, causing the cross-shaped plate 10 and the four electric suction cups 11 to descend until they contact the topmost corrugated paper 2. The four electric suction cups 11 then activate, generating negative pressure to firmly hold the single sheet of corrugated paper 2. Finally, the electric telescopic rod 9 retracts. Once positioned, the corrugated paper 2, which is then fixed by adsorption, is raised to a height slightly above the positioning roller 22. Then, motor 5 is started in reverse, driving the moving seat 7 to move to the left. When the left end of the corrugated paper 2 moves above the positioning roller 22, the electric telescopic rod 9 is extended, causing the lower surface of the corrugated paper 2 to contact the positioning roller 22. The electric telescopic rod 9 is then stopped, completing the precise positioning of the corrugated paper 2 during transfer. As motor 5 continues to reverse, the corrugated paper 2 continues to move to the left. During this process, the corrugated paper 2 gradually moves between the three lower flat rollers 19 and the three upper flat rollers 21, effectively eliminating wrinkles and warping of the corrugated paper 2. To ensure the corrugated paper 2 is flat, when the left end of the flattened corrugated paper 2 enters between the lower conveyor roller 3 and the upper conveyor roller 17, the four electric suction cups 11 are turned off to release the suction and fixation of the corrugated paper 2. At this time, by utilizing the synchronous relative rotation of the lower conveyor roller 3 and the upper conveyor roller 17, the corrugated paper 2 can be smoothly conveyed to the left to the paper inlet of the high-speed laminating machine for feeding. This allows the flattening and feeding of the corrugated paper 2 to be carried out simultaneously, ensuring that the corrugated paper 2 enters the high-speed laminating machine in a flat state. In the subsequent processing of bonding the corrugated paper 2 with the face paper, it can ensure that the contact surface is flat, reduce defects such as bubbles and misalignment, and improve the quality of the finished product.

[0050] After a single feeding is completed, the above process is repeated to achieve continuous automated feeding, which can transport the corrugated paper 2 sheets one by one into the high-speed mounting machine.
