Technical Field

[0001] The utility model relates to the technical field of laminating machines, and more specifically, to a transmission mechanism of a laminating machine. Background Technique

[0002] A laminating machine is a device used for laminating, folding, and mounting paper or cardboard, and is commonly used in the printing industry and the binding industry. It can bond the cover and inner pages of printed materials together, while folding and sorting them, making the final product more beautiful and stable. The transmission mechanism of the laminating machine plays a crucial role in transporting paper or cardboard during the laminating process, affecting the normal operation and laminating quality of the laminating machine.

[0003] The existing transmission mechanisms of laminating machines mostly convey paper or cardboard to the laminating area through rollers. However, only by using rollers to convey paper or cardboard, once the paper or cardboard has wrinkles, it will cause the paper or cardboard to deform and be damaged after laminating. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, adapt to the actual needs, and provide a transmission mechanism of a laminating machine to solve the technical problem that in the prior art, only rollers are used to convey paper or cardboard, and once the paper or cardboard has wrinkles, it will cause the paper or cardboard to deform and be damaged after laminating.

[0005] To solve the above technical problems, the utility model provides the following technical solution: A transmission mechanism of a laminating machine includes a frame. A plurality of synchronously rotating conveyor rollers are rotatably connected to the inner wall of the frame. A conveyor belt is sleeved on the outer wall of the conveyor roller. A motor is fixedly connected to the outer wall of the frame. The main shaft of the motor penetrates the outer wall of the frame and is fixedly connected to the rotating shaft of the conveyor roller. A plurality of symmetrically arranged chutes are opened on the inner wall of the frame. A slider is slidably connected to the inner wall of the chute. A connecting column is fixedly connected to the outer wall of the slider. The other end of the connecting column is hinged to an inclined connecting plate. The other end of the connecting plate is rotatably connected to an adjusting disk. A tension spring is fixedly connected to the end wall of the connecting column. The other end of the tension spring is fixedly connected to the outer wall of the connecting plate. A plurality of symmetrically arranged traction blocks are fixedly connected to the outer wall of the conveyor belt. The top of the traction block is arc-shaped, and when the traction block moves along with the conveyor belt, it can push against the bottom of the slider; the paper or cardboard is respectively conveyed onto the conveyor belt, and the paper or cardboard is located between two adjacent traction blocks. The motor runs to drive the conveyor belt to convey the paper or cardboard through the conveyor roller. During this process, the adjusting disk automatically pulls the paper, making the paper or cardboard flat, and automatically stops pulling the paper or cardboard after the paper or cardboard is flattened, preventing the paper or cardboard from being torn, thereby preventing the paper or cardboard from deforming and wrinkling after laminating.

[0006] Preferably, the adjusting disc is made of rubber material, and the outer ring of the adjusting disc is a laminated structure, and the laminations of the adjusting disc are inclined; the rubber material of the adjusting disc enables the laminations on its outer ring to sandwich the paper or cardboard in the middle when rotating along with it and cooperating with the conveyor belt. Therefore, when the inclined laminations of the adjusting disc contact the paper, they will bend. When the adjusting disc no longer flattens and pulls the paper or cardboard, the laminations of the adjusting disc will pull the paper under their own resilience, thereby increasing the flatness of the paper during transportation and increasing the flatness of the paper or cardboard when this mechanism is used as a transmission mechanism of a laminating machine for paper or cardboard transportation.

[0007] Preferably, a laying roller is rotatably connected to the inner wall of the frame; by providing the laying roller, the laying roller can sandwich the paper to flatten it.

[0008] Preferably, a sponge ring sleeving the laying roller is fixedly connected to the outer wall of the laying roller, and the outer wall of the sponge ring abuts against the outer wall of the conveyor belt; when the sponge ring outside the laying roller contacts the conveyor belt, it can be squeezed and deformed, so that the contact area between the sponge ring and the conveyor belt increases, thereby enabling the laying roller to flatten the paper or cardboard through the sponge ring.

[0009] Preferably, a pressure spring is fixedly connected to the top of the slider, and the other end of the pressure spring is fixedly connected to the top inner wall of the chute; by providing the pressure spring to push the slider, the smoothness of the slider moving in the chute is increased, preventing the slider from being unable to move inside the chute due to its own gravity. And the elastic force generated by the pressure spring can transmit the pressure to the connecting column, the connecting plate and the adjusting disc through the slider in sequence, so that the adjusting disc abuts against the conveyor belt under the pressure of the pressure spring, increasing the effect of the adjusting disc pulling the paper or cardboard.

[0010] Preferably, the outer wall of the portion of the bottom of the slider pushed by the traction block is arc-shaped; the arc-shaped portions at the bottom of the slider and the arc-shaped portion of the traction block can guide each other when contacting, reducing the probability of wear and jamming between the two.

[0011] Compared with the prior art, the beneficial effects of the present utility model are:

By providing a frame, a conveying roller, a conveyor belt, a motor, a chute, a slider, a connecting column, a connecting plate, an adjusting disc, and a tension spring, the present utility model transports paper or cardboard to the conveyor belt respectively, and makes the paper or cardboard located between two adjacent traction blocks. The motor runs to drive the conveyor belt to transport the paper or cardboard through the conveying roller. During this process, the adjusting disc automatically pulls the paper to flatten it, and automatically stops pulling the paper or cardboard after the paper or cardboard is flattened, preventing the paper or cardboard from being torn, thereby preventing the paper or cardboard from deforming and wrinkling after lamination.

[0013] 2. In the present utility model, the rubber material of the adjusting disk enables the laminations on its outer ring to sandwich the paper or cardboard in the middle when rotating along with it. Therefore, when the inclined laminations of the adjusting disk come into contact with the paper, they will bend. And when the adjusting disk no longer flattens and pulls the paper or cardboard, the laminations of the adjusting disk will pull the paper under their own resilience, thereby increasing the flatness of the paper during transportation and increasing the flatness of this mechanism when used as a paper or cardboard conveying mechanism of a laminating machine.

[0021] As Figures 1 to 5As shown in the figure, the present utility model relates to a mounting machine transmission mechanism, which includes a frame 1. A plurality of synchronously rotating conveyor rollers 2 are rotatably connected to the inner wall of the frame 1. A conveyor belt 3 is sleeved on the outer wall of the conveyor roller 2. A motor 4 is fixedly connected to the outer wall of the frame 1. The main shaft of the motor 4 penetrates through the outer wall of the frame 1 and is fixedly connected to the rotating shaft of the conveyor roller 2. A plurality of symmetrically arranged chutes 5 are opened on the inner wall of the frame 1. A slider 6 is slidably connected to the inner wall of the chute 5. A connecting column 7 is fixedly connected to the outer wall of the slider 6. The other end of the connecting column 7 is hinged with an inclined connecting plate 8. The other end of the connecting plate 8 is rotatably connected with an adjusting disc 9. A tension spring 10 is fixedly connected to the end wall of the connecting column 7. The other end of the tension spring 10 is fixedly connected to the outer wall of the connecting plate 8. A plurality of symmetrically arranged traction blocks 11 are fixedly connected to the outer wall of the conveyor belt 3. The top of the traction block 11 is arc-shaped, and the bottom of the slider 6 can be pushed when the traction block 11 moves along with the conveyor belt 3; the paper or cardboard is respectively conveyed onto the conveyor belt 3, and the paper or cardboard is located between two adjacent traction blocks 11. The motor 4 operates to drive the conveyor belt 3 to convey the paper or cardboard through the conveyor roller 2. During this process, the adjusting disc 9 automatically traction the paper, making the paper or cardboard flat, and automatically stop traction on the paper or cardboard after the paper or cardboard is flattened, preventing the paper or cardboard from being torn, so as to prevent the paper or cardboard from deforming and wrinkling after lamination.

[0022] Further, the adjusting disc 9 is made of rubber material, and the outer ring of the adjusting disc 9 is a laminated structure, and the laminations of the adjusting disc 9 are inclined; the rubber material of the adjusting disc 9 makes the laminations of its outer ring bend when contacting the paper or cardboard because the paper or cardboard is clamped in the middle when the outer ring rotates in cooperation with the conveyor belt 3. When the adjusting disc 9 is no longer flattening and traction the paper or cardboard, the laminations of the adjusting disc 9 will pull the paper under its own resilience, thereby increasing the flatness of the paper during conveying, and increasing the flatness of the mechanism when it is used as a mounting machine transmission mechanism to convey paper or cardboard.

[0023] Further, a laying roller 12 is rotatably connected to the inner wall of the frame 1; by setting the laying roller 12, the laying roller 12 can clamp the paper, thereby flattening the paper.

[0024] Further, a sponge ring 13 is fixedly connected to the outer wall of the laying roller 12 and sleeved thereon. The outer wall of the sponge ring 13 abuts against the outer wall of the conveyor belt 3; when the sponge ring 13 outside the laying roller 12 contacts the conveyor belt 3, it can be deformed by extrusion, so that the contact area between the sponge ring 13 and the conveyor belt 3 is increased, thereby enabling the laying roller 12 to flatten the paper or cardboard through the sponge ring 13.

[0025] Furthermore, a compression spring 14 is fixedly connected to the top of the slider 6, and the other end of the compression spring 14 is fixedly connected to the inner wall of the top of the chute 5; by providing the compression spring 14 to push and squeeze the slider 6, the smoothness of the slider 6 when moving in the chute 5 is increased, preventing the slider 6 from being unable to move inside the chute 5 due to its own gravity, and the elastic force generated by the compression spring 14 can transmit the pressure to the connecting column 7, the connecting plate 8, and the adjusting disc 9 in sequence through the slider 6, so that the adjusting disc 9 presses against the conveyor belt 3 under the pressure of the compression spring 14, increasing the effect of the adjusting disc 9 when pulling the paper or cardboard.

[0026] Furthermore, the outer wall of the slider 6 at the position where the bottom is pushed by the traction block 11 is arc-shaped; the arc-shaped part at the bottom of the slider 6 and the arc-shaped part of the traction block 11 can guide each other when they come into contact, reducing the probability of wear and jamming between the two.

[0027] Working principle: This embodiment provides a mounting machine transmission mechanism. When in use, the bracket is connected to the mounting machine, and this mechanism drives the mounting machine for mounting. By respectively conveying the paper or cardboard onto the conveyor belt 3, and making the paper or cardboard located between two adjacent traction blocks 11, the motor 4 operates to drive the conveyor belt 3 to convey the paper or cardboard through the conveying roller 2. During this process, the elastic force generated by the compression spring 14 can transmit the pressure to the connecting column 7, the connecting plate 8, and the adjusting disc 9 in sequence through the slider 6, so that the adjusting disc 9 presses against the conveyor belt 3 under the pressure of the compression spring 14. As the paper or cardboard is conveyed, the paper or cardboard will be clamped between the adjusting disc 9 and the conveyor belt 3. The adjusting disc 9 tilts along with the connecting disc, and the rotation of the adjusting disc 9 will pull and traction the paper or cardboard to both sides, thereby pulling and flattening the paper or cardboard. During this process, when the paper traction is completed, the reaction force generated when the adjusting disc 9 pulls and tractions the paper or cardboard will cause the adjusting disc 9 to pull the connecting plate 8 to twist, so that the connecting plate 8 and the adjusting disc 9 no longer tilt when starting to twist, so that the adjusting disc 9 no longer tractions the paper or cardboard when rotating, thereby preventing the paper or cardboard from being over-tractioned and torn. As the conveyor belt 3 rotates, the conveyor belt 3 will drive the traction block 11 to rotate together. When the traction block 11 rotates, it will push and squeeze the bottom of the slider 6, so that the slider 6 squeezes the compression spring 14 and starts to move upward, so that the slider 6 drives the connecting column 7 to move upward, and the connecting column 7 drives the adjusting disc 9 to move upward through the connecting plate 8, so that the adjusting disc 9 no longer contacts the conveyor belt 3. At this time, the tension spring 10 will pull the connecting plate 8 to twist under its own tension, so that the connecting plate 8 drives the adjusting disc 9 to tilt again, so as to prepare for the next traction of the paper or cardboard.
