Description

Technical Field

[0001] This utility model relates to the field of hot melt adhesive composite pressing technology, specifically an adjustable hot melt adhesive composite pressing mechanism. Background Technology

[0002] Hot melt adhesive composite pressing technology is widely used in the composite processing of various materials such as leather, cloth, paper, and plastics, achieving a stable bond between multiple layers of materials through the adhesive effect of hot melt adhesive.

[0003] Existing equipment lacks an effective adhesive layer smoothing structure, resulting in defects such as bubbles, wrinkles, and inconsistent bonding strength in the composite material. Furthermore, the existing equipment is inconvenient to clean. After the equipment has been running for a period of time, hot melt adhesive residue is easily left on the surface of the conveying components and pressing structure. Traditional cleaning methods require manual operation after the machine is stopped, which is not only time-consuming and labor-intensive but also affects production efficiency. For composite materials of different specifications, the adjustment range of the existing equipment is limited, making it difficult to achieve rapid and accurate parameter adjustments, thus limiting the applicability and production flexibility of the equipment.

[0004] Therefore, this utility model provides an adjustable hot melt adhesive composite pressing mechanism to solve the above problems. Utility Model Content

[0005] This invention provides an adjustable hot melt adhesive composite pressing mechanism, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable hot melt adhesive composite pressing mechanism, comprising a base plate, a gantry frame mounted above the base plate, a groove with two open sides inside the gantry frame, two first motors mounted above the gantry frame, each output end of the first motors connected to a screw, and a slider with a nut connected to the outside of each screw, a long rod connected to one side of the slider, a pressure roller mounted on the outside of the long rod, a first connecting rod connected to the other side of the slider, a connecting block connected to the other end of the first connecting rod, a second connecting rod connected to the bottom surface of the connecting block, a mounting plate connected to the bottom surface of the second connecting rod, a scraper connected to the side of the mounting plate, and an adhesive spraying assembly and a conveying assembly arranged above the base plate.

[0007] As a preferred technical solution of this application, the surface of the bottom support plate has two rectangular openings, each rectangular opening is provided with a retractable baffle, each baffle is connected with a handle, and the bottom surface of the bottom support plate is provided with an L-shaped groove facing the rectangular opening.

[0008] As a preferred technical solution of this application, the adhesive spraying assembly includes a first bracket installed above the base plate, a pipe installed inside the first bracket, and a set of spray guns installed on the bottom surface of the pipe.

[0009] As a preferred technical solution of this application, a second bracket is installed above the bottom support plate, a lead screw is rotatably installed inside the second bracket, a second motor is installed on the surface of the second bracket, and the output end of the second motor is connected to the lead screw.

[0010] As a preferred technical solution of this application, the conveying assembly includes two sets of support plates mounted on the bottom support plate. Each set of support plates is rotatably connected to a rotating rod. A conveyor belt is mounted on both rotating rods. A third motor is mounted on the outer side of one of the support plates, and the output end of the third motor is connected to one of the rotating rods.

[0011] As a preferred technical solution of this application, the bottom surface of the base plate is equipped with four support legs, and the bottom surface of each support leg is equipped with a base.

[0012] This invention uses a first motor to drive a screw to rotate, which in turn moves a slider along the screw. This allows for height adjustment of the long rod connected to the slider and the external pressure roller, enabling precise adjustment of the pressing gap and pressure according to the thickness of different materials. This meets the composite needs of various material specifications and effectively solves the problem of poor adaptability of traditional fixed pressing structures. On the other side of the slider, a first connecting rod, a connecting block, and a second connecting rod connect a mounting plate and a scraper, forming a linkage structure between the scraper and the pressure roller. When the height of the pressure roller is adjusted, the position of the scraper is adjusted synchronously, allowing for the smoothing of the hot melt adhesive coated on the material surface before pressing. This avoids composite defects caused by hot melt adhesive accumulation and uneven distribution. This design ensures the uniformity of the adhesive layer, reduces problems such as air bubbles and localized poor adhesion, and significantly improves the bonding quality and surface smoothness of composite materials.

[0020] 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.

[0021] This utility model provides an adjustable hot melt adhesive composite pressing mechanism, such as... Figure 1-5 As shown, the system includes a base plate 1, a gantry frame 2 mounted on top of the base plate 1, and a groove with two open sides inside the gantry frame 2. Two first motors 3 are mounted on top of the gantry frame 2, and the output ends of the first motors 3 are connected to screws 4. The outside of the screws 4 are connected to sliders 5 with nuts. One side of the sliders 5 is connected to a long rod 6, and a pressure roller 7 is mounted on the outside of the long rod 6. The other side of the sliders 5 is connected to a first connecting rod 8, and the other end of the first connecting rod 8 is connected to a connecting block 9. The bottom surface of the connecting block 9 is connected to a second connecting rod 10, and the bottom surface of the second connecting rod 10 is connected to a mounting plate 11. The side of the mounting plate 11 is connected to a scraper 12. A glue spraying assembly and a conveying assembly are set above the base plate 1. When the material is conveyed to the area below the pressure roller 7, the first motors 3 on the gantry frame 2 drive the screws 4 to rotate, causing the sliders 5 to move up and down along the screws 4, thereby adjusting the height of the pressure roller 7 to meet the composite pressing requirements of materials of different thicknesses.

[0022] Two rectangular openings are provided on the surface of the base plate 1. Each rectangular opening is equipped with a retractable baffle 13. Each baffle 13 is connected to a handle 14. An L-shaped groove 15 is installed on the bottom surface of the base plate 1 opposite the rectangular opening. The scraper 12 can clean up excess hot melt adhesive to ensure the quality of composite pressing. By pulling the baffle 13 with the handle 14, the scraper 12 and the mounting plate 11 can clean up the excess hot melt adhesive. The excess hot melt adhesive will fall from the rectangular opening into the L-shaped groove 15 and slide out from the L-shaped groove 15 for recycling.

[0023] The adhesive spraying assembly includes a first bracket 20 installed above the base plate 1. A pipe 21 is installed inside the first bracket 20, and a set of spray guns 22 is installed on the bottom surface of the pipe 21. The pipe 21 is connected to an external material supply device. The spray guns 22 can spray the adhesive onto the material to be laminated. A second bracket 23 is installed above the base plate 1. A lead screw 25 is rotatably installed inside the second bracket 23. A second motor 24 is installed on the surface of the second bracket 23. The output end of the second motor 24 is connected to the lead screw 25. A second material to be laminated can be placed on the outside of the lead screw 25. The second motor 24 drives the lead screw 25 to rotate, so that the material on the lead screw 25 can be placed onto the first material that has been sprayed with adhesive.

[0024] The conveying assembly includes two sets of support plates 26 mounted on the base plate 1. Each set of support plates 26 is rotatably connected to a rotating rod 17. A conveyor belt 16 is mounted on both rotating rods 17. A third motor 27 is mounted on the outer side of one of the support plates 26. The output end of the third motor 27 is connected to one of the rotating rods 17. The surface of the rotating rod 17 is treated with anti-slip material to enhance the friction between it and the conveyor belt 16 and ensure the stability of the conveying. The rotating rod 17 is driven to rotate by the third motor 27, which in turn drives the conveyor belt 16 to operate, thereby achieving stable material conveying.

[0025] Four support legs 18 are installed on the bottom surface of the base plate 1. Each support leg 18 has a base 19 installed on its bottom surface. These support legs 18 are arranged symmetrically to ensure the balance and stability of the entire mechanism. Shock-absorbing pads are installed at the bottom of the base 19. The shock-absorbing pads can absorb the vibration generated by the mechanism during operation, reduce the impact on the ground, and also reduce the noise generated by the mechanism due to vibration.

[0026] Working principle: In use, the third motor 27 drives the rotating rod 17 to rotate, which in turn causes the conveyor belt 16 to operate. The operator places the first material to be laminated on the conveyor belt 16, which transports the material to below the spray gun 22. The feeding device connected to the pipe 21 supplies the material, and the hot melt adhesive is sprayed from the spray gun 22 through the pipe 21, evenly coating the surface of the first material. The operator places the second material on the lead screw 25, and the second motor 24 drives the lead screw 25 to rotate, causing the second material to come into contact with the first material that has been sprayed with adhesive. As the conveyor belt 16 continues to operate, they are transported to below the pressure roller 7. By controlling the first motor 3... The first motor 3 drives the screw 4 to rotate. When the screw 4 rotates, the slider 5 moves up and down along the screw 4, thereby adjusting the height of the pressure roller 7. This ensures that the pressure roller 7 can press the two materials together with appropriate pressure, guaranteeing the composite pressing effect. During the pressing process, the scraper 12 will stick to the material surface and scrape off the excess hot melt adhesive. By pulling the baffle 13 with the handle 14, the scraped hot melt adhesive will fall into the L-shaped chute 15 through the rectangular opening and be recycled, avoiding the waste of hot melt adhesive. Through this adjustable design, the mechanism can adapt to composite materials of different specifications, achieve rapid and accurate parameter adjustment, and improve the applicability and production flexibility of the equipment.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
