Description

Technical Field

[0001] This utility model belongs to the field of coating device technology, and more specifically, it relates to a coating device that prevents glue from splashing. Background Technology

[0002] Coating equipment is an industrial device that uses a specific structure to uniformly and precisely coat fluid materials such as adhesives, coatings, and inks onto the surface of a substrate. Its core function is to form a coating of a predetermined thickness on substrates such as paper, film, metal plates, and electronic components. It is widely used in packaging, electronics, textiles, building materials, and many other fields. However, most commonly used traditional coating equipment uses columnar or dot-shaped discharge, resulting in a long drop path for the adhesive. Low-viscosity adhesives, due to their high fluidity, are prone to deviating from the feeding trajectory during the drop, causing dripping and spreading splashing, which leads to substrate contamination and material waste. Therefore, a new type of coating equipment that prevents adhesive splashing is needed. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a coating device to prevent glue splashing, thereby solving the problem that dripping or splashing easily occurs when using low-viscosity glue in existing traditional coating devices.

[0004] This utility model discloses a coating device for preventing glue splattering, which is achieved by the following specific technical means:

[0005] A coating device for preventing glue splattering includes a fixed frame, a storage tank, and a movable frame;

[0006] The fixed frame has a conveyor belt on its upper side and a connecting frame installed on the upper side of the center end of the fixed frame. The connecting frame has a set of round holes on its left and right sides respectively. A set of electric cylinders is fixedly connected inside the two sets of round holes on the connecting frame. The storage tank is placed on the upper end of the connecting frame, and a sealing cover is movably connected to the inner side of the upper end of the storage tank. The sealing cover has a set of exhaust pipes and a set of feed pipes. An exhaust valve is installed on the exhaust pipe. A discharge pipe is connected to the lower end of the storage tank. The lower end of the discharge pipe passes through the connecting frame. An electrically controlled valve is installed on the discharge pipe. The movable frame is placed inside the connecting frame. The top surface of the connecting frame is connected to the push rods of the two sets of electric cylinders. A roller is clamped on the inner side of the movable frame. A servo motor is installed on the outer side of the movable frame. The motor shaft of the servo motor is connected to the roller.

[0007] Furthermore, a heating tube is provided inside the storage tank, a motor is installed inside the sealing cover, a stirring component is provided on the lower side of the sealing cover, and the motor shaft of the motor inside the sealing cover is connected to the stirring component.

[0008] Furthermore, a pressure sensor is installed inside the roller, and a rubber sleeve is fitted on the outside of the roller, with a set of rubber retaining rings fitted on the outer sides of the left and right ends of the rubber sleeve.

[0009] Furthermore, two sets of electric push rods are installed on the front side of the movable frame, and the electric push rods are inclined. The push rods of the electric push rods are inserted into the inside of the movable frame, and a set of scrapers are movably connected to the push rods of the two sets of electric push rods.

[0010] Furthermore, the upper side of the movable frame is provided with a square groove, and a discharge component is connected inside the square groove on the upper side of the movable frame. A corrugated pipe is connected to the upper side of the discharge component, and the corrugated pipe is connected to the lower side of the discharge pipe. The discharge port on the lower side of the discharge component is flat, and the lower end surface of the discharge component is arc-shaped, close to the outer surface of the rubber sleeve.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This utility model uses a rubber sleeve, which is fitted on the outside of the roller. The elasticity and high adhesion of the rubber sleeve can adapt to the slight unevenness of the workpiece surface when in contact with the workpiece, ensuring the coating fit and avoiding glue splashing caused by local gaps. At the same time, it enhances the adhesion of the glue to the roller surface and reduces the dripping and splashing of low viscosity glue.

[0013] 2. This utility model features a movable frame with two sets of electric push rods mounted on the front. A scraper is movably connected to the push rods of the two sets of electric push rods. When this utility model is connected to a control device, the two sets of electric push rods are driven synchronously, which is beneficial for accurately adjusting the distance between the scraper and the rubber sleeve, adapting to the needs of different thicknesses of adhesive film, and avoiding centrifugal force splashing caused by excessively thick adhesive film on the rubber sleeve 13.

[0014] 3. This utility model, by setting up a discharge component, with its lower end surface being arc-shaped and close to the outer surface of the rubber sleeve, shortens the path of the adhesive falling, avoiding splashing caused by the adhesive dripping and spreading under gravity. It is especially suitable for low viscosity adhesives. The flat discharge port of the discharge component can spread the adhesive evenly on the surface of the rubber sleeve in a strip shape, avoiding local accumulation caused by point or columnar feeding, reducing squeezing and splashing during subsequent scraping by the scraper, and improving coating consistency.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] Example:

[0024] As attached Figure 1 To be continued Figure 5 As shown:

[0025] This utility model provides a coating device to prevent glue splashing, including a fixed frame 1, a storage tank 5, and a movable frame 6;

[0026] A conveyor belt 2 is provided on the upper side of the fixed frame 1, and a connecting frame 3 is installed on the upper side of the center end of the fixed frame 1. A set of round holes are provided on the left and right sides of the connecting frame 3. A set of electric cylinders 4 are fixedly connected inside the two sets of round holes on the connecting frame 3. The storage tank 5 is placed on the upper end of the connecting frame 3, and a sealing cover plate 17 is movably connected to the inner side of the upper end of the storage tank 5. A set of exhaust pipes 20 and a set of feed pipes 21 are provided on the sealing cover plate 17. An exhaust valve is installed on the set of exhaust pipes 20. A discharge pipe 10 is connected to the lower end of the storage tank 5. The lower end of the discharge pipe 10 passes through the connecting frame 3. An electric control valve 11 is installed on the discharge pipe 10. The movable frame 6 is placed inside the connecting frame 3. The top surface of the connecting frame 3 is connected to the push rods of the two sets of electric cylinders 4. A roller 14 is clamped on the inner side of the movable frame 6. A servo motor 7 is installed on the outer side of the movable frame 6. The motor shaft of the servo motor 7 is connected to the roller 14.

[0027] Among them, such as Figure 4 and Figure 5As shown, a heating tube 18 is provided inside the storage tank 5, a motor is installed inside the sealing cover plate 17, and a stirring element 19 is provided on the lower side of the sealing cover plate 17. The motor shaft of the motor inside the sealing cover plate 17 is connected to the stirring element 19. The heating tube 18 inside the storage tank 5 facilitates the control of the glue temperature and ensures that the glue is in the best flow state. The motor drives the stirring element to continuously stir the glue, expelling air bubbles inside the glue and preventing splashing caused by the bursting of air bubbles when the roller 14 and the rubber sleeve 13 are applied in conjunction.

[0028] Among them, such as Figure 3 As shown, a pressure sensor is installed inside the roller 14, and a rubber sleeve 13 is fitted on the outside of the roller 14. A set of rubber retaining rings 15 are fitted on the outer sides of the left and right ends of the rubber sleeve 13. The pressure sensor installed inside the roller 14 monitors the pressure when the roller 14 contacts the workpiece in real time. After the data feedback, the height of the movable frame 6 is adjusted by the electric cylinder 4, which is conducive to dynamically adapting to the thickness of the workpiece. Utilizing the elasticity and high adhesion of the rubber sleeve 13, it can adapt to the slight unevenness of the workpiece surface when in contact with the workpiece, ensuring the coating adhesion and avoiding glue splashing caused by local gaps. At the same time, it enhances the adhesion of the glue on the roller surface and reduces the dripping and splashing of low viscosity glue.

[0029] Among them, such as Figure 3 As shown, two sets of electric push rods 12 are installed on the front side of the movable frame 6, and the electric push rods 12 are inclined. The push rods of the electric push rods 12 are inserted into the inner side of the movable frame 6, and a set of scrapers 16 are movably connected to the push rods of the two sets of electric push rods 12. When this utility model is connected to the control equipment, the two sets of electric push rods 12 are driven synchronously, which is conducive to accurately adjusting the distance between the scraper 16 and the rubber sleeve 13, adapting to the needs of different thicknesses of adhesive film, and avoiding the centrifugal force splashing caused by excessively thick adhesive film on the rubber sleeve 13.

[0030] As shown in Figure 3, the upper side of the movable frame 6 is provided with a square groove, and a discharge component 8 is connected inside the square groove on the upper side of the movable frame 6. A corrugated pipe 9 is connected to the upper side of the discharge component 8, and the corrugated pipe 9 is connected to the lower side of the feeding pipe 10. The lower discharge port of the discharge component 8 is flat, and the lower end surface of the discharge component 8 is arc-shaped, close to the outer surface of the rubber sleeve 13. By making the lower end surface of the discharge component 8 arc-shaped and close to the outer surface of the rubber sleeve 13, the falling path of the glue is shortened, avoiding splashing caused by the glue dripping and spreading under the action of gravity. It is especially suitable for low viscosity glue. The flat discharge port of the discharge component 8 can spread the glue evenly on the surface of the rubber sleeve 13 in a strip shape, avoiding local accumulation caused by point or columnar feeding, reducing squeezing and splashing during subsequent scraping by the scraper, and improving coating consistency.

[0031] The specific usage and function of this embodiment are as follows:

[0032] like Figures 1 to 5 As shown. A heating tube 18 is installed inside the storage tank 5 to facilitate temperature control of the adhesive, ensuring it remains in an optimal flow state. A motor drives a stirring component to continuously agitate the adhesive, expelling air bubbles and preventing splashing during subsequent application by the roller 14 and rubber sleeve 13. A set of scrapers 16 is movably connected to the push rods of two sets of electric push rods 12. When connected to a control device, the two sets of electric push rods 12 are driven synchronously, facilitating precise adjustment of the distance between the scraper 16 and the rubber sleeve 13, ensuring proper fit. To meet the requirement of consistent adhesive film thickness, and to avoid centrifugal force-induced splashing caused by excessively thick adhesive film on the rubber sleeve 13, the lower surface of the discharge part 8 is arc-shaped and close to the outer surface of the rubber sleeve 13, shortening the path of the adhesive and preventing splashing caused by the adhesive dripping and spreading under gravity. It is especially suitable for low-viscosity adhesives. The flat discharge port of the discharge part 8 can spread the adhesive evenly on the surface of the rubber sleeve 13 in a strip shape, avoiding local accumulation caused by dot or columnar feeding, reducing squeezing and splashing during subsequent scraping by the scraper, and improving coating consistency.
