Description

Technical Field

[0001] This utility model relates to the field of rubber backing technology, specifically to an automatic bonding and rolling defoaming backing device for the surface of rubber products. Background Technology

[0002] The automated bonding and defoaming adhesive application device for rubber products is a highly integrated intelligent system. Through automated control technology, it achieves precise positioning and offset-free bonding between the rubber substrate and the adhesive tape or film. Utilizing mechanical rolling combined with dynamic pressure adjustment, auxiliary vibration, or airflow impact, it systematically eliminates residual air bubbles at the interface between the adhesive layer and the substrate, ultimately forming a uniform, dense, and firmly bonded composite structure. This device integrates high-precision motion control, intelligent pressure feedback, and online quality inspection technologies. It can adapt to the adhesive application requirements of rubber products of different shapes, sizes, and materials, significantly improving production efficiency and product yield. It is a key piece of equipment in modern manufacturing for achieving efficient and high-quality surface treatment of rubber products.

[0003] Existing automated rubber product laminating devices still require operators to manually open and close the extrusion cover to handle rubber products due to the lack of automated loading and unloading and cover plate linkage design. This operation not only demands frequent manual intervention in the production process, significantly increasing equipment downtime, but also disrupts the overall production cycle because the pace of manual operation is difficult to match with the automation speed of the laminating process. This leads to longer processing cycles per piece, reduced equipment utilization, and ultimately hinders the scaling up of production lines and the release of production capacity.

[0004] Therefore, we propose an automatic bonding and rolling defoaming adhesive device for the surface of rubber products. Utility Model Content

[0005] The purpose of this invention is to provide an automatic bonding and rolling defoaming adhesive device for the surface of rubber products, so as to solve the problems mentioned in the background art.

[0006] 1. To achieve the above objectives, this utility model provides the following technical solution: an automatic bonding and rolling defoaming adhesive device for the surface of rubber products, comprising: The base has support columns fixedly connected at equal intervals at the bottom and vertical plates fixedly connected symmetrically at the top. The closing mechanism includes a guide groove. The guide groove is formed on the surface of the two vertical plates when they are close to each other. A limit block is slidably installed inside the guide groove. A rotating rod is rotatably installed between the two limit blocks. A connecting block is fixedly connected to the outside of the rotating rod.

[0007] Preferably, the closing mechanism further includes a fixed frame, with the fixed frame fixedly connected to the bottom of the connecting block, a cover plate installed on the top of the fixed frame, and a placement box rotatably mounted on the bottom of the cover plate. Guide grooves formed on the surfaces where the vertical plates approach each other provide a sliding path for the limiting block. The limiting block drives the rotating rod and the externally fixed connecting block to move downwards, and the fixed frame at the bottom of the connecting block moves downwards synchronously, causing the cover plate to gradually approach the placement box. Simultaneously, the connecting rods and telescopic rods, which are sequentially and equidistantly fixed on the top of the cover plate, work together. The springs sleeved on the outside of the telescopic rods are compressed during the downward movement of the cover plate, utilizing the elastic potential energy of the springs to provide a stable pre-pressure for the cover plate, ensuring a tight seal between the cover plate and the placement box.

[0008] Preferably, an extrusion plate is installed at the bottom of the cover plate.

[0009] Preferably, ventilation holes are provided at equal intervals on both sides of the placement box.

[0010] Preferably, the top of the cover plate is fixedly connected with connecting rods at equal intervals. A telescopic rod is installed at the other end of each connecting rod, and the bottom of the telescopic rod is fixedly connected to the fixed frame. A spring is installed on the outside of the telescopic rod. A bracket is fixedly connected to the top of the base. A hydraulic motor is installed at the top center of the bracket, and an extrusion plate is installed at the bottom of the bracket. The output end of the hydraulic motor passes through the inside of the bracket and is fixedly connected to the extrusion plate. When the hydraulic motor installed at the center of the bracket at the top of the base is started, its output end passes through the inside of the bracket and drives the extrusion plate at the bottom to move downwards. The extrusion plate applies uniform and controllable pressure to the cover plate. The extrusion plate installed at the bottom of the cover plate further transmits the pressure between the rubber product and the adhesive backing, achieving a tight fit between the two.

[0011] Preferably, the base has a sliding groove inside, and a sliding block is slidably installed inside the sliding groove. A threaded rod is rotatably installed at the bottom of the base, and the outer side of the threaded rod is engaged with the inside of the sliding block. The top of the sliding block is fixedly connected to the placement box. A rotary motor is installed at one end of the threaded rod, and the output end of the rotary motor is fixedly connected to the threaded rod. When the rotary motor at the bottom of the base starts to operate, its output end drives the threaded rod to rotate synchronously. Since the outer side of the threaded rod is engaged with the inside of the sliding block, and the top of the sliding block is fixed to the placement box, under the transmission action of the threaded rod, the sliding block moves linearly along the sliding groove inside the base, thereby driving the placement box to move precisely to the bonding operation area, completing the positioning step before processing.

[0012] Preferably, a support plate is fixedly connected to the front end of the vertical plate, a connecting roller is rotatably installed between the two support plates, and a pressure roller is installed on the outside of the connecting roller.

[0013] Compared with the prior art, the beneficial effects of this utility model are: Significantly improving production efficiency and enabling continuous operation: The device, through the automated operation of the closing mechanism, automatically opens the cover after bonding, eliminating the need for manual operation and completely eliminating waiting time and interference from manual actions. Simultaneously, the coordinated operation of the rotating motor, threaded rod, and sliding block enables the placement box to automatically complete positioning and movement, as well as the switching between finished products and workpieces. This allows the equipment to immediately enter the next production cycle after completing one bonding and defoaming operation, effectively shortening the single-piece processing cycle, improving the overall utilization rate of the equipment, and overcoming the production cycle interruption problem caused by manual intervention in traditional devices, thus meeting the demands of large-scale production capacity.

[0016] 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.

[0017] Please see Figure 1-4 An automatic bonding and rolling defoaming adhesive device for the surface of rubber products, comprising: The base 1 has support columns 2 fixedly connected at equal intervals at the bottom and vertical plates 3 fixedly connected symmetrically at the top. The closing mechanism includes a guide groove 4. The guide groove 4 is formed on the surface of the two vertical plates 3 when they are close to each other. A limit block 5 is slidably installed inside the guide groove 4. A rotating rod 6 is rotatably installed between the two limit blocks 5. A connecting block 7 is fixedly connected to the outside of the rotating rod 6.

[0018] Please see Figure 2 The closing mechanism also includes a fixed frame 8, which is fixedly connected to the bottom of the connecting block 7. A cover plate 9 is installed on the top of the fixed frame 8, and a placement box 10 is rotatably installed on the bottom of the cover plate 9. The guide groove 4 opened on the surface of the vertical plates 3 when they are close to each other provides a sliding path for the limiting block 5. The limiting block 5 drives the rotating rod 6 and the connecting block 7 fixed on the outside to move downward. The fixed frame 8 at the bottom of the connecting block 7 moves downward synchronously, causing the cover plate 9 to gradually approach the placement box 10. At the same time, the connecting rods 13 and the telescopic rods 14, which are fixed at equal intervals on the top of the cover plate 9, work together. The springs 15 sleeved on the outside of the telescopic rods 14 are compressed during the downward movement of the cover plate 9. The elastic potential energy of the springs 15 provides a stable pre-pressure for the cover plate 9, ensuring the tightness and sealing between the cover plate 9 and the placement box 10.

[0019] Please see Figure 2 An extrusion plate 11 is installed at the bottom of the cover plate 9.

[0020] Please see Figure 2 Ventilation holes 12 are provided at equal intervals on both sides of the placement box 10.

[0021] Please see Figure 3 The top of the cover plate 9 is fixedly connected with connecting rods 13 at equal intervals. A telescopic rod 14 is installed at the other end of each connecting rod 13, and the bottom of the telescopic rod 14 is fixedly connected to the fixed frame 8. A spring 15 is installed on the outside of the telescopic rod 14. A bracket 16 is fixedly connected to the top of the base 1. A hydraulic motor 17 is installed at the top center of the bracket 16, and an extrusion plate 18 is installed at the bottom of the bracket 16. The output end of the hydraulic motor 17 passes through the interior of the bracket 16 and is fixedly connected to the extrusion plate 18. When the hydraulic motor 17 installed at the center of the bracket 16 at the top of the base 1 is activated, its output end passes through the interior of the bracket 16 and drives the extrusion plate 18 at the bottom to move downwards. The extrusion plate 18 applies uniform and controllable pressure to the cover plate 9. The extrusion sheet 11 installed at the bottom of the cover plate 9 further transmits the pressure between the rubber product and the adhesive backing, achieving a tight fit between the two.

[0022] Please see Figure 4The base 1 has a sliding groove 19 inside, and a sliding block 20 is slidably installed inside the sliding groove 19. A threaded rod 21 is rotatably installed at the bottom of the base 1, and the outer side of the threaded rod 21 is engaged with the inside of the sliding block 20. The top of the sliding block 20 is fixedly connected to the placement box 10. A rotary motor 22 is installed at one end of the threaded rod 21, and the output end of the rotary motor 22 is fixedly connected to the threaded rod 21. When the rotary motor 22 at the bottom of the base 1 starts to operate, its output end drives the threaded rod 21 to rotate synchronously. Since the outer side of the threaded rod 21 is engaged with the inside of the sliding block 20, and the top of the sliding block 20 is fixed to the placement box 10, under the transmission action of the threaded rod 21, the sliding block 20 moves linearly along the sliding groove 19 inside the base 1, thereby driving the placement box 10 to move precisely to the bonding operation area, completing the positioning step before processing.

[0023] Please see Figure 1 The front end of the vertical plate 3 is fixedly connected to a support plate 23, and a connecting roller 24 is rotatably installed between the two support plates 23. A pressure roller 25 is installed on the outside of the connecting roller 24.

[0024] Working principle: The first stage is the equipment startup and initial preparation phase. The operator places the rubber product to be processed stably inside the placement box 10. The pre-set ventilation holes 12 on both sides of the placement box 10 ensure air circulation during the subsequent bonding process, avoiding air bubbles due to local sealing. At this time, the rotating motor 22 at the bottom of the base 1 starts to run, and its output end drives the threaded rod 21 to rotate synchronously. Since the outer side of the threaded rod 21 is engaged with the inside of the sliding block 20, and the top of the sliding block 20 is fixed to the placement box 10, under the transmission action of the threaded rod 21, the sliding block 20 moves linearly along the sliding groove 19 opened inside the base 1, thereby driving the placement box 10 to move precisely to the bonding operation area, completing the positioning step before processing. Once the placement box 10 reaches the designated position, the closing mechanism is activated to achieve automatic closing and pressurized contact of the cover 9. The guide grooves 4 on the surfaces of the vertical plates 3 near each other provide a sliding path for the limiting block 5. The limiting block 5 drives the rotating rod 6 and the externally fixed connecting block 7 to move downwards. The fixing frame 8 at the bottom of the connecting block 7 moves downwards synchronously, causing the cover 9 to gradually approach the placement box 10. Simultaneously, the connecting rods 13 and telescopic rods 14, which are sequentially and equidistantly fixed at the top of the cover 9, work together. The spring 15 sleeved on the outside of the telescopic rod 14 is compressed during the downward movement of the cover 9, utilizing the elastic potential energy of the spring 15 to provide a stable pre-pressure for the cover 9, ensuring a tight seal between the cover 9 and the placement box 10. Subsequently, the hydraulic motor 17 installed at the center of the top bracket 16 of the base 1 starts, and its output end passes through the inside of the bracket 16 and drives the bottom extrusion plate 18 to move downward. The extrusion plate 18 applies uniform and controllable pressure to the cover plate 9. The extrusion sheet 11 installed at the bottom of the cover plate 9 further transmits the pressure to the rubber product and the backing adhesive, so as to achieve a tight fit between the two. During this process, the vent 12 helps to discharge some of the air initially generated at the bonding interface, laying the foundation for subsequent defoaming. Finally, in the automatic opening and next cycle transition, after the bonding and defoaming operations are completed, the hydraulic motor 17 drives the extrusion plate 18 to return to its original position, the spring 15 on the outside of the telescopic rod 14 returns to its original deformation, pushing the cover plate 9 upward. The limit block 5 slides upward along the guide groove 4, driving the rotating rod 6, connecting block 7, and fixing frame 8 back to their initial positions, thus achieving automatic opening of the cover plate 9 without manual operation. At the same time, the rotating motor 22 starts running again, and through the transmission action of the threaded rod 21 and the sliding block 20, the processed rubber product is moved out of the bonding area along with the placement box 10, making it convenient for operators to pick up and put away finished products. Then, the sliding block 20 drives the empty placement box 10 back to the work area, and the equipment immediately enters the next production cycle.
