Description

Technical Field

[0001] This utility model relates to the field of rubber product processing technology, specifically to a rubber product coating device. Background Technology

[0002] In the production of rubber products, it is often necessary to apply adhesive to their surface to facilitate subsequent bonding, lamination, or encapsulation processes. Traditional adhesive application methods rely heavily on manual operation, which is not only inefficient but also makes it difficult to guarantee the thickness and uniformity of the adhesive application, resulting in poor product quality stability.

[0003] To address the aforementioned problems, some automated adhesive coating equipment has emerged in the prior art. For example, patent CN219273498U discloses a rubber product adhesive coating device, including a control cabinet, operation panel, vertical plate, servo motor, adhesive roller, fixed roller, and adhesive tank. The servo motor drives the adhesive roller to dip into the adhesive tank and then coat the rubber bushing above it with adhesive. While this device improves efficiency to some extent, it still has significant drawbacks: First, it uses an open adhesive tank, and the adhesive roller rotates inside the tank to dip into the adhesive, resulting in a large area of ​​adhesive being exposed to the air, making it prone to evaporation, solidification, and skin formation. This not only wastes adhesive but also allows the skinned impurities to contaminate the workpiece, affecting the coating quality. Second, this device lacks an active control mechanism for the thickness and uniformity of the adhesive layer after coating; the coating effect depends entirely on the amount of adhesive applied, and excess adhesive can only flow naturally by gravity, which cannot meet the process requirements of high-precision products.

[0004] Therefore, developing a device that can precisely control the glue supply, avoid glue contamination, and actively ensure the uniformity of glue application is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0018] Preferably, the opening and closing component further includes:

[0019] A secondary rotating shaft rotatably connected to the outside of the processing table;

[0020] A worm gear fixedly connected to the middle of the outer side of the secondary shaft;

[0021] The worm gear is in contact with the worm and is connected in a meshing rotational manner.

[0022] Preferably, the opening and closing component further includes:

[0023] A valve plate fixedly connected to the bottom of the secondary rotating shaft;

[0031] The second toothed disc is in contact with the first toothed disc and is in a meshing rotatable connection;

[0032] The set roller is rotatably connected to the inside of the processing table via a second toothed disc.

[0033] Preferably, the opening and closing component further includes:

[0034] A material outlet seat is fixedly connected to the inner side of the processing table, and the position of the material outlet seat corresponds to that of the glue coating roller.

[0035] The discharge seat is connected to the dispensing port of the glue injection mechanism.

[0036] Preferably, the adhesive scraper assembly further includes:

[0037] A rail seat fixedly connected to the inner side of the processing table;

[0046] The beneficial effects of this utility model are as follows:

[0047] 1. Precise and controllable glue supply method: This patent controls glue dispensing through an independent glue injection mechanism and an opening and closing assembly driven by a worm gear, replacing the method in the prior art where the glue roller dips into an open glue tank. This method allows for on-demand and quantitative delivery of glue directly to the coating area, avoiding glue exposure, evaporation, and contamination at the source, ensuring stable glue quality, and reducing waste.

[0048] 2. Active and Adjustable Adhesive Scraping Function: This patent features a specially designed, motor-driven adhesive scraping component with precisely controllable position. This component actively scrapes away excess adhesive from the workpiece surface after application, ensuring the uniformity of the adhesive layer. In contrast, the prior art relies solely on gravity to drip off excess adhesive, which has limited effectiveness in controlling the thickness and uniformity of the adhesive layer. The adhesive scraping function of this patent is an active and precisely controllable finishing step.

[0049] 3. Integrated power and transmission design: This patent achieves synchronous counter-rotation of the coating roller and the mounting roller through the meshing of the first and second gear discs. This design not only stably transports and coats the workpiece, but also applies a "squeezing" or "flattening" effect to the workpiece through the relative movement of the two rollers, which helps to spread the adhesive evenly. This is a function that the fixed support roller in the prior art does not have. Attached Figure Description

[0056] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0057] Please see Figures 1 to 4 This utility model provides a rubber product coating device. Its core design concept is to improve coating quality and efficiency by organically combining three links: controllable glue supply, collaborative coating and active glue scraping.

[0058] Basic Structure and Workflow: The main body of the device is the processing table 1, which provides the mounting base for other components. A dispensing mechanism 2 for storing and supplying adhesive is located on the side of the processing table 1. In practical applications, the dispensing mechanism 2 can be a pressure glue tank with heating and insulation functions to ensure the fluidity of the adhesive. The processing table 1 is equipped with an opening and closing assembly 3 for controlling the dispensing of adhesive from the dispensing mechanism 2, a glue application assembly 4 for performing the glue application task, and a scraping assembly 5 for fine-tuning the glued workpiece.

[0059] Implementation details of the opening and closing assembly 3: The opening and closing assembly 3 is key to achieving precise glue supply. It includes symmetrically fixed support seats 32 on the outside of the processing table 1, with a first motor 33 fixedly mounted on one of the support seats 32. A main rotating shaft 34 is rotatably connected to the middle of the two sets of support seats 32. The main rotating shaft 34 is fixedly connected to the output end of the first motor 33, so that it can be precisely driven by the first motor 33. A worm gear 341 is fixedly connected to the outside of the main rotating shaft 34. A secondary rotating shaft 35 is also rotatably connected to the outside of the processing table 1. A worm wheel 351 that meshes with the worm gear 341 is fixedly mounted in the middle of the secondary rotating shaft 35. This worm gear transmission has a self-locking characteristic, which can ensure the stable position of the valve plate 36 in the non-driven state and prevent glue leakage. The valve plate 36 is fixedly connected to the bottom of the secondary rotating shaft 35. The valve plate 36 is located at the glue outlet port inside the glue dispensing mechanism 2. When the first motor 33 drives the secondary shaft 35 to rotate 90 degrees via the worm gear 341 and worm wheel 351, the valve plate 36 rotates accordingly, thereby opening and closing the glue outlet. A material outlet seat 31 is also fixedly connected to the inner side of the processing table 1, which is connected to the glue outlet port of the glue injection mechanism 2, and is used to guide the glue liquid to below the coating roller 42.

[0060] Implementation details of the adhesive application assembly 4: The adhesive application assembly 4 is responsible for uniformly applying adhesive to the surface of the workpiece. It includes a second motor 41 fixedly mounted on the outside of the processing table 1. The output end of the second motor 41 is fixedly connected to the adhesive application roller 42, providing it with rotational power. A first toothed disc 421 is fixed to the other end of the adhesive application roller 42. A mounting roller 43 is rotatably connected to the inside of the processing table 1 via bearings or other structures, and a second toothed disc 431 is fixed to its outside. The first toothed disc 421 and the second toothed disc 431 mesh with each other. This allows the mounting roller 43 to rotate synchronously and in the opposite direction when the second motor 41 drives the adhesive application roller 42 to rotate. Rubber products to be coated, such as rubber tubes and sleeves, can be mounted on the mounting roller 43. During operation, the adhesive flows out from the discharge seat 31, is adhered to by the rotating adhesive application roller 42, and then, through the relative rolling between the adhesive application roller 42 and the mounting roller 43 with the workpiece mounted, the adhesive is uniformly squeezed and applied to the outer surface of the workpiece. This synchronous counter-rotation design enhances the spreading effect of the adhesive, resulting in a more uniform coating.

[0061] Implementation details of the adhesive scraper assembly 5: The adhesive scraper assembly 5 is an important part for refining the adhesive application effect. It includes a rail base 51 fixedly connected to the inside of the processing table 1. A forward / reverse motor 52 is fixedly mounted on the top of the rail base 51, and its output end is fixedly connected to a threaded rod 521 located inside the rail base 51. A slide 53 engages with the threaded rod 521 through a threaded hole. The forward / reverse motor 52 can drive the threaded rod 521 to rotate forward and backward, thereby driving the slide 53 to move precisely forward or backward in a straight line along the rail base 51. A scraper blade 531 is fixedly mounted on the bottom of the slide 53, and its blade shape can match the outer contour of the workpiece. After the workpiece is coated with adhesive, the forward / reverse motor 52 is activated, causing the slide 53 to move the scraper blade 531 to a preset appropriate distance from the workpiece surface, scraping away excess and uneven adhesive from the rotating workpiece surface. Below the scraper blade 531, a collection seat 54 is placed on the inner side of the processing table 1 to collect the scraped waste glue, keep the working environment clean, and facilitate the centralized disposal of waste materials.

[0062] Working Principle Overview: During operation, the rubber product is first placed on the mounting roller 43. The second motor 41 is started, driving the coating roller 42 to rotate synchronously in the opposite direction to the mounting roller 43. Then, the first motor 33 is started, driving the valve plate 36 through the worm gear 341 and worm wheel 351. The adhesive flows through the discharge seat 31 to the coating roller 42 and is applied to the rotating workpiece. Finally, the forward and reverse motors 52 are started, driving the scraper blade 531 forward to the working position to scrape off excess adhesive, which falls into the collection seat 54. The entire process achieves fully automated control from adhesive supply and coating to finishing, significantly improving coating quality and efficiency.

[0063] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
