[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] Example

[0024] like Figures 1 to 5 As shown, the present invention proposes a bonding device for an automatic gluing mechanism for microfiber leather, including a bracket 1. Mounting plates 2 are provided on both sides of the top surface of the bracket 1, and the mounting plates 2 are fixedly connected to the bracket 1. A driving mechanism is provided on the outer side of the mounting plates 2. The driving mechanism includes a base 26 connected to one side of the mounting plates 2, which is fixedly connected to the mounting plates 2. A driving motor 27 is provided on the top surface of the base 26, and is fixedly connected to the base 26. A connecting shaft 28 is connected to the output end of the driving motor 27, and is fixedly connected to the output end of the driving motor 27. A gear 29 is provided on the outer ring of the connecting shaft 28, and is fixedly connected to the connecting shaft 28.

[0025] One side of the extrusion roller 11 passes through the mounting plate 2 and is connected to a gear 30 that meshes with a gear 29. The gear 30 is fixedly connected to the extrusion roller 11. One side of the gear 30 is connected to a pulley 31 on the outer ring of the extrusion roller 11. The pulley 31 is fixedly connected to the extrusion roller 11. One end of the transmission roller 12 passes through the mounting plate 2 and is connected to a pulley 32. The pulley 32 is fixedly connected to the transmission roller 12. The outer rings of the pulleys 31 and 32 are fitted with the same drive belt 33. Through the setting of the drive mechanism, the extrusion roller and the transmission roller can be rotated synchronously.

[0026] A material roll 3 is rotatably mounted on the inner side of the mounting plate 2. A U-shaped groove is opened on the mounting plate 2 corresponding to the position of the material roll 3. The U-shaped groove is slidably connected to the material roll 3. The U-shaped groove on the mounting plate facilitates the operator to replace the material roll 3. A pad 5 is connected between the mounting plates 2. The pad 5 is fixedly connected to the mounting plate 2. A conveyor belt for the glue coating mechanism to feed material is set on one side of the pad 5 below the material roll 3. An extrusion roller 6 is set on one side of the pad 5. The pad 5 is located between the conveyor belt and the extrusion roller 6. The pad 5 is set to fill the gap and at the same time provides a certain support for the microfiber leather that is not glued above.

[0027] Above the first extrusion roller 6, there is a second extrusion roller 11. To the right of the first extrusion roller 6, inside the mounting plate 2, there are multiple transmission rollers 12. One of the transmission rollers 12 is connected to the first extrusion roller 6. Below the tension adjustment mechanism, inside the mounting plate 2, there are three third extrusion rollers 35. Inside the mounting plate 2, at the position of the tension adjustment mechanism, there is a tension sensor 34. By setting the tension sensor 34, the tension of the microfiber leather can be monitored in real time and converted into an electrical signal, so as to achieve precise control of the tension during the production process, thereby ensuring that the microfiber leather will not have quality problems due to excessive or insufficient tension during the bonding process.

[0028] The tension adjustment mechanism includes two sleeves 13 disposed inside the mounting plates 2 on both sides. The sleeves 13 are fixedly connected to the mounting plates 2. By setting the sleeves 13, the entire tension adjustment mechanism is fixedly supported. A rotating plate 14 is rotatably disposed on the side of each sleeve 13 that is close to each other. A circular plate 15 is connected inside one of the sleeves 13. The circular plate 15 is fixedly connected to the sleeve 13. A motor 16 is disposed on one side of the circular plate 15. The motor 16 is fixedly connected to the circular plate 15. The output end of the motor 16 is fixedly connected to the rotating plate 14 through a rotating shaft. By setting the motor 16 and the rotating plate 14, the entire assembly located between the two rotating plates 14 can be driven to rotate. This allows the tension adjustment mechanism to rotate along with the microfiber leather transmission without obstructing the transmission of the microfiber leather during the tension adjustment process.

[0029] Another sleeve 13 is equipped with a second motor 17, which is fixedly connected to the inner side of the corresponding mounting plate 2. The rotating plate 14 has a circular hole corresponding to the output end of the second motor 17. The output end of the second motor 17 is rotatably connected to the rotating plate 14 and is equipped with a rack 18. The rack 18 is fixedly connected to the output end of the second motor 17. A roller 19 is meshed on the outer ring of the rack 18. A base plate 20 is provided on the outer ring of the roller 19. The base plate 20 is rotatably connected to the roller 19. Six limiting blocks 21 are evenly arranged in the base plate 20. A sliding groove is opened on the base plate 20 corresponding to the limiting block 21. The limiting block 21 is slidably connected to the sliding groove. A limiting plate 22 is provided on one side of the base plate 20 connected to the outer ring of the roller 19.

[0030] The limiting plate 22 is fixedly connected to the roller 19. Limiting rods 23 are connected to the limiting blocks 21 on the side near the limiting plate 22 and are slidably connected to the limiting plate 22. The limiting rods 23 are fixedly connected to the limiting blocks 21. Fixing rods 24 are connected to the sides of the rotating plates 14 that are close to each other. The fixing rods 24 pass through each base plate 20 and are fixedly connected to both the rotating plate 14 and the base plate 20. The fixing rods 24 ensure that the fixedly connected rotating plate 14 and base plate 20 are in close proximity. By keeping the limiting plate 22 stationary as it rotates with the roller shaft 19, the limiting block 21 and the limiting rod 23 can move along the sliding groove. Each of the limiting blocks 21 located in the same position has a support plate 25 connected to one side. The support plate 25 is fixedly connected to the limiting block 21. By setting the support plate 25 and the limiting block 21, the support plate can be pushed outward or retracted inward during the movement of the limiting block 21, thereby pressing down on the microfiber leather in contact with the support plate 25 to increase tension, or retracting to reduce tension.

[0031] In this embodiment, during the microfiber leather bonding process, the drive motor 27 starts, and the output end of the motor drives the connected shaft 28 to rotate. The connected shaft 28 drives the first extrusion roller 6 to rotate and also drives the first gear 29 to rotate. The first gear 29 drives the second gear 30 meshing with it to rotate. The second gear 30 drives the second extrusion roller 11 to rotate, and at the same time drives the pulley 31 connected to one end of the second extrusion roller 11 to rotate. The pulley 31 drives the second pulley 32 to rotate through the drive belt 33 sleeved between the pulley 32 and the second pulley, and then drives the transmission roller 12 connected to the pulley to rotate. The microfiber leather to be bonded is conveyed by the conveyor belt to the bonding channel between the first extrusion roller 6 and the second extrusion roller 11, and is bonded through each transmission roller 12 and the tension adjustment mechanism.

[0032] During the bonding process, the tension adjustment mechanism detects changes in the tension of the microfiber leather by the tension sensor 34 and converts them into electrical signals, activating motor 17. The output of motor 17 drives the rack 18 to rotate, which in turn drives the meshing roller 19 to rotate. The rotation of roller 19 drives the outer ring fixedly connected limit plate 22 to rotate, which in turn drives the limit rod 23 to slide along the corresponding sliding groove. The sliding of the limit rod 23 drives the limit block 21, which is fixed in the base plate by the fixed rod 24, to move outward. The movement of the limit block 21 drives the fixedly connected support plate 25 to move outward, thereby adjusting the tension of the microfiber leather. At the same time, it cooperates with the extrusion roller 35 to bond and extrude the microfiber leather. During the tension adjustment process, motor 16 and drive motor 27 start synchronously. The rotation of motor 16 drives the rotating plate 14 to rotate, which in turn drives the entire part between the two rotating plates 14 to rotate.
