Description

Technical Field

[0001] This application relates to the field of sponge production technology, specifically to an automatic sponge adhesive coating device. Background Technology

[0002] Sponges are a common porous elastic material with soft and elastic properties. They are mainly divided into two categories: natural sponges and synthetic sponges. Natural sponges are derived from marine organisms and are natural and environmentally friendly; synthetic sponges are made through chemical processes, and are diverse in type and cost-controllable. Both are widely used in many fields. The production and processing of sponges requires the application of adhesives.

[0003] Existing sponge coating technology mainly relies on manual application. Manual application is not only inefficient, but also cannot guarantee the uniform application of glue, resulting in poor coating quality. After the glue dries and hardens in uneven areas, the sponge surface is not smooth, affecting the quality of the sponge. Since it is done directly by hand, it is easy to waste glue, and the utilization efficiency of glue is not high. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides an automatic sponge adhesive application device, which has the advantages of automatically completing the sponge adhesive application operation, saving manpower, improving work efficiency and adhesive utilization, ensuring adhesive uniformity, and improving adhesive quality, thus solving the problems in the background technology.

[0005] To achieve the above objectives, this application provides the following technical solution: an automatic sponge adhesive applicator, comprising a base, with equidistantly arranged conveying rollers rotatably connected inside the base, a first bracket fixedly connected to the upper surface of the base, an adhesive trough fixedly connected to the top of the first bracket, a conveying pipe fixedly connected to the top of the adhesive trough, and equidistantly arranged adhesive outlet pipes connected to the bottom of the conveying pipes. An adhesive outlet is provided at the bottom of the adhesive trough. An adhesive roller is provided inside the first bracket, an adjusting plate is slidably connected inside the adhesive trough, and two lifting plates are slidably connected inside the first bracket via a slot. Both ends of the adhesive roller are rotatably connected to the interior of the lifting plates. Two side plates are fixedly connected to the outer surface of the base, each side plate having a rotating shaft rotatably connected inside. A fixing frame is fixedly connected to the outer surface of each lifting plate, and the rotating shaft is threadedly connected to the fixing frame via a threaded structure on its outer circumference. A second bracket is fixedly connected to the upper surface of the base, a cleaning roller is rotatably connected inside the second bracket, and a vacuuming device is installed on the upper surface of the second bracket, with equidistantly arranged vacuuming pipes fixedly connected inside the vacuuming device.

[0006] The above solution addresses the problem that manual glue application is inefficient, cannot guarantee uniform glue application, results in poor glue quality, and easily leads to glue waste and low glue utilization. By setting up conveyor rollers, glue troughs, glue outlets, glue rollers, and adjusting plates, the sponge conveying and glue application operations can be completed automatically, saving manpower, improving work efficiency and glue utilization, ensuring glue uniformity, and improving glue quality.

[0007] Furthermore, sliding plates are fixedly connected to both sides of the adjustment plate, and the outer surface of the sliding plates is slidably connected to the glue groove through a groove inside the glue groove.

[0008] The above solution involves setting sliding plates on both sides of the adjusting plate and making the sliding plates slide in the grooves inside the glue tank. This structure makes the sliding of the adjusting plate in the glue tank more stable, ensuring the accuracy and reliability of the adjusting plate in adjusting the amount of glue in the glue tank, thereby ensuring the stability and uniformity of the glue application process.

[0009] Furthermore, two horizontal plates are fixedly connected to the outer surface of the glue tank, and each horizontal plate is threaded with a positioning rod inside, and a handwheel is fixedly connected to the top of each positioning rod.

[0010] With the above method, once the adjustment plate is moved to the appropriate position, the positioning rod is moved downward by rotating the handwheel to fix the adjustment plate in the current position, preventing the adjustment plate from moving during the glue application process and ensuring stable glue application quality.

[0011] Furthermore, each of the lifting plates has a guide plate fixedly connected to its outer surface, and the outer surface of the guide plate is slidably connected to the first bracket through a guide groove provided inside the first bracket.

[0012] Through the above scheme, the guide plate provides a stable guiding effect for the lifting plate, ensuring that the lifting plate remains vertical during movement and preventing it from shifting or tilting. This ensures that the rubber roller can accurately and stably adjust its height, guaranteeing the contact pressure and coating effect between the rubber roller and the sponge.

[0013] Furthermore, the base is equipped with a first motor, and the output shaft and the rotating shaft of the first motor are connected by a sprocket and a chain drive.

[0014] The above scheme involves installing a first motor inside the base and using sprockets and chains to achieve a transmission connection between the output shaft of the first motor and the rotating shaft. This transmission method is simple and reliable, and can precisely control the rotation of the rotating shaft, thereby driving the lifting plate to move up and down, achieving precise adjustment of the height of the glue roller, meeting the glue application requirements of sponges of different thicknesses, and improving the applicability and automation of the device.

[0015] Furthermore, the interior of the glue tank has a funnel-shaped structure, the glue roller is located directly below the glue outlet, and the dust suction pipe is symmetrically arranged on both sides of the second bracket.

[0016] The above design incorporates a funnel-shaped structure inside the glue tank, which facilitates the natural convergence of the adhesive within the tank and allows it to flow smoothly from the outlet. This ensures uniformity and stability of the adhesive application. The glue roller is positioned directly below the outlet, ensuring that the adhesive flowing from the outlet is accurately applied to the roller, which then evenly spreads the adhesive onto the sponge surface. This improves the precision and efficiency of the adhesive application. The suction pipes are symmetrically positioned on both sides of the second support, enabling more comprehensive cleaning of any dust or impurities that may be present on the sponge surface before adhesive application. This ensures the cleanliness of the sponge surface and thus improves the quality of the adhesive application and the overall product quality.

[0017] Furthermore, the outer surface of the second bracket is fixedly connected with equidistant reinforcing rings, and the end of the reinforcing ring away from the second bracket is fixedly sleeved with the outer circumferential surface of the vacuum tube.

[0018] The above-mentioned method can reinforce the vacuum cleaner hose, improve its stability, and effectively prevent it from loosening or falling off during operation due to vibration or other external forces.

[0019] Furthermore, adjacent conveying rollers are connected by sprockets and chains, one end of one of the conveying rollers is equipped with a second motor, the cleaning roller and one of the conveying rollers are connected by sprockets and chains, and one end of the rubber roller is equipped with a third motor.

[0020] The above scheme uses a second motor to drive one of the conveying rollers to rotate, and then uses sprockets and chains to achieve transmission between adjacent conveying rollers, so that all conveying rollers can rotate synchronously, achieving stable conveying of the sponge and ensuring the continuity and stability of the sponge in the glue coating process. The rotation of the conveying roller drives the rotation of the cleaning roller, eliminating the need for an additional drive device, simplifying the device structure and reducing costs. The third motor independently drives the glue roller to rotate, which can precisely control the rotation speed of the glue roller.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects: This automatic sponge gluing device, equipped with conveyor rollers, a glue tank, a glue outlet, a glue roller, and an adjusting plate, can automatically complete the conveying and gluing of sponges, saving manpower, improving work efficiency and glue utilization, ensuring uniformity of gluing, and improving gluing quality. By incorporating cleaning rollers, a dust collection device, and a dust collection pipe, the gluing surface of the sponge can be cleaned before gluing, further optimizing the subsequent gluing effect. A first motor drives a rotating shaft to rotate under the action of a sprocket and chain, causing the fixed frame to move the lifting plate and glue roller up and down. This allows the height of the glue roller to be adjusted according to the thickness of the sponge, completing the gluing operation for sponges of different thicknesses, improving the flexibility and practicality of the gluing device.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] Please see Figure 1 , Figure 3 and Figure 5An automatic sponge gluing device in this embodiment includes a base 1. Equally spaced conveyor rollers 2 are rotatably connected inside the base 1. A first support 3 is fixedly connected to the upper surface of the base 1. A glue trough 4 is fixedly connected to the top of the first support 3. A conveying pipe 5 is fixedly connected to the top of the glue trough 4. Equally spaced glue outlet pipes 6 are connected to the bottom of the conveying pipe 5. A glue outlet 7 is provided at the bottom of the glue trough 4. A glue roller 8 is provided inside the first support 3. An adjusting plate 9 is slidably connected inside the glue trough 4. Two lifting plates 13 are slidably connected inside the first support 3 through a slot. The two ends of the glue roller 8 are rotatably connected to the interior of the lifting plates 13. Two side plates 15 are fixedly connected to the outer surface of the base 1. A rotating shaft 16 is rotatably connected inside each side plate 15. A fixing frame 17 is fixedly connected to the outer surface of each lifting plate 13. The rotating shaft 16 is threadedly connected to the fixing frame 17 through a threaded structure on its outer circumference.

[0026] Please see Figure 1 and Figure 2 A second bracket 21 is fixedly connected to the upper surface of the base 1. A cleaning roller 22 is rotatably connected inside the second bracket 21. A vacuum cleaner 23 is installed on the upper surface of the second bracket 21. Vacuum cleaner pipes 24 arranged at equal intervals are fixedly connected inside the vacuum cleaner 23.

[0027] Please see Figure 5 and Figure 6 The two sides of the adjusting plate 9 are fixedly connected with sliding plates 10. The outer surface of the sliding plates 10 is slidably connected to the glue groove 4 through a groove opened inside the glue groove 4. By setting the sliding plates 10 on both sides of the adjusting plate 9 and making the sliding plates 10 slidably connected to the groove opened inside the glue groove 4, this structure makes the sliding of the adjusting plate 9 in the glue groove 4 more stable, ensuring the accuracy and reliability of the adjusting plate 9 in adjusting the amount of glue in the glue groove 4, thereby ensuring the stability and uniformity of the glue application process.

[0028] Please see Figure 3 , Figure 5 and Figure 6 Two horizontal plates 11 are fixedly connected to the outer surface of the glue tank 4. Each horizontal plate 11 is threaded with a positioning rod 12 inside. Each positioning rod 12 is fixedly connected to a handwheel at its top. When the adjusting plate 9 is moved to the appropriate position, the positioning rod 12 is moved downward by rotating the handwheel to fix the adjusting plate 9 in the current position, preventing the adjusting plate 9 from moving during the glue application process and ensuring stable glue application quality.

[0029] Please see Figure 3 and Figure 4Each lifting plate 13 has a guide plate 14 fixedly connected to its outer surface. The outer surface of the guide plate 14 is slidably connected to the first bracket 3 through guide grooves opened inside the first bracket 3. The guide plate 14 provides a stable guiding effect for the lifting of the lifting plate 13, so that the lifting plate 13 always remains vertical during the movement, avoiding the lifting plate 13 from deviating or tilting during the movement, thereby ensuring that the rubber roller 8 can accurately and stably adjust its height, and ensuring the contact pressure and coating effect between the rubber roller 8 and the sponge.

[0030] Please see Figure 1 and Figure 3 The base 1 is equipped with a first motor 18. The output shaft of the first motor 18 and the rotating shaft 16 are connected by a sprocket and a chain. The first motor 18 is installed inside the base 1, and the transmission connection between the output shaft of the first motor 18 and the rotating shaft 16 is realized through the sprocket and chain. This transmission method is simple and reliable, and can accurately control the rotation of the rotating shaft 16, thereby driving the lifting plate 13 to move up and down, realizing the precise adjustment of the height of the glue roller 8, meeting the glue application requirements of sponges of different thicknesses, and improving the applicability and automation of the device.

[0031] Please see Figure 1 , Figure 2 and Figure 5 The glue tank 4 has a funnel-shaped internal structure. The glue roller 8 is located directly below the glue outlet 7. The dust suction pipes 24 are symmetrically arranged on both sides of the second bracket 21. The funnel-shaped internal structure of the glue tank 4 facilitates the natural convergence of the glue in the glue tank 4, making it easy for the glue to flow out smoothly from the glue outlet 7, while ensuring the uniformity and stability of the glue dispensing. The glue roller 8 is located directly below the glue outlet 7, ensuring that the glue flowing out from the glue outlet 7 can be accurately applied to the glue roller 8, and then the glue roller 8 will evenly apply the glue to the sponge surface, improving the accuracy and efficiency of the glue application. The dust suction pipes 24 are symmetrically arranged on both sides of the second bracket 21, which can more thoroughly clean the dust, impurities, etc. that may exist on the sponge surface before glue application, ensuring the cleanliness of the sponge surface, thereby improving the glue application quality and product quality.

[0032] Please see Figure 1 and Figure 2 The outer surface of the second bracket 21 is fixedly connected with equidistant reinforcing rings 25. The end of the reinforcing ring 25 away from the second bracket 21 is fixedly sleeved with the outer circumferential surface of the suction pipe 24. The reinforcing ring 25 can reinforce the suction pipe 24, improve the stability of the suction pipe 24, and effectively prevent the suction pipe 24 from loosening or falling off due to vibration or other external forces during operation.

[0033] Please see Figure 1 , Figure 3 and Figure 4Adjacent conveyor rollers 2 are connected by sprockets and chains. One end of one conveyor roller 2 is equipped with a second motor 19. The cleaning roller 22 is connected to one of the conveyor rollers 2 by sprockets and chains. One end of the glue roller 8 is equipped with a third motor 20. The second motor 19 drives one of the conveyor rollers 2 to rotate. The sprockets and chains are used to realize the transmission between adjacent conveyor rollers 2, so that all conveyor rollers 2 can rotate synchronously, realize the stable conveying of sponge, and ensure the continuity and stability of sponge in the glue coating process. The rotation of the conveyor roller 2 drives the cleaning roller 22 to rotate, eliminating the need for an additional drive device, simplifying the device structure and reducing costs. The third motor 20 independently drives the glue roller 8 to rotate, which can precisely control the rotation speed of the glue roller 8.

[0034] This embodiment of an automatic sponge gluing device, by setting up a conveying roller 2, a glue tank 4, a glue outlet 7, a glue roller 8, and an adjusting plate 9, can automatically complete the sponge conveying and gluing operations, saving manpower, improving work efficiency and glue utilization, ensuring the uniformity of gluing, and improving gluing quality. By setting up a cleaning roller 22, a dust collection device 23, and a dust collection pipe 24, the glue-coating surface of the sponge can be cleaned before gluing, further optimizing the subsequent gluing effect. The first motor 18 drives the rotating shaft 16 to rotate under the action of the sprocket and chain, causing the fixed frame 17 to drive the lifting plate 13 and the glue roller 8 to rise and fall. Thus, the height of the glue roller 8 can be adjusted according to the thickness of the sponge to complete the gluing operation of sponges of different thicknesses, improving the flexibility and practicality of the gluing device.

[0035] It should be noted that the first motor 18, the second motor 19, and the third motor 20 are all servo motors.

[0036] The working principle of the above embodiments is as follows: The second motor 19 is started, driving one of the conveyor rollers 2 to rotate. Under the transmission action of the sprockets and chains of the adjacent conveyor rollers 2, all conveyor rollers 2 rotate synchronously, achieving stable conveying of the sponge. At the same time, when one of the conveyor rollers 2 rotates, it drives the cleaning roller 22 to rotate through the sprockets and chains. When the sponge passes the second support 21, the cleaning roller 22 rotates and cleans the surface of the sponge. Meanwhile, the dust collection device 23 collects dust and other debris from the cleaning roller 22 during the cleaning process through the dust collection pipe 24, completing the cleaning operation of the sponge surface. The cleaned sponge continues to be conveyed to the glue coating area. The conveying pipe 5 can be connected to an external glue pump. The glue pump injects the glue liquid evenly into the glue tank 4 through the conveying pipe 5 and the glue outlet pipe 6. The glue liquid in the glue tank 4 flows out onto the glue roller 8 through the glue outlet 7. The third motor 2 is started. The drive roller 8 rotates synchronously with the sponge. When the cleaned sponge passes under the roller 8, the roller 8 evenly applies the adhesive to the sponge surface, and the adhesive application is completed. The movable adjustment plate 9 controls the size of the glue outlet 7, and the amount of adhesive applied can be adjusted as needed. The positioning rod 12 can be rotated by handwheel to move the positioning rod 12 down to squeeze and position the adjustment plate 9, preventing the adjustment plate 9 from moving easily. After the adhesive application is completed, the glue outlet 7 can be completely closed by the adjustment plate 9. The first motor 18 can be started, and the rotating shaft 16 is driven to rotate under the transmission of the sprocket and chain. Since the rotating shaft 16 is threadedly connected to the fixed frame 17, the fixed frame 17 drives the lifting plate 13 and the roller 8 to rise and fall. The roller 8 is adjusted to a suitable height according to the thickness of the sponge to perform adhesive application on sponges of different thicknesses.
