Abstract
Description
Technical Field
[0001] This utility model relates to the field of sealing layer production technology, specifically to a synthetic paint spraying device for sealing layer of advertising boards. Background Technology
[0002] The sealing layer of an advertising board refers to a protective material that covers the surface of the advertising board. It is mainly used to prevent moisture, dust and other external factors from eroding and damaging the surface of the advertising board. The sealing layer is usually made of polymer materials and has good waterproof, dustproof and UV protection functions, which can extend the service life of the advertising board and maintain its clean and beautiful appearance.
[0003] During the production of the advertising board sealing layer, workers need to spray synthetic paints with different properties onto the sealing layer using a synthetic paint spraying device to achieve the corresponding functions of the advertising board sealing layer. Most existing synthetic paint spraying devices for advertising board sealing layers have fixed nozzles during use. However, the specifications of the advertising board sealing layer change during the production process. When smaller sizes enter the spraying device, a large portion of the synthetic paint sprayed from the nozzles cannot adhere to the advertising board sealing layer, resulting in significant waste.
[0004] In summary, the existing synthetic paint spraying equipment for the sealing layer of advertising boards, with its fixed sets of nozzles, causes significant waste when spraying the sealing layer of smaller advertising boards. Utility Model Content
[0005] The purpose of this utility model is to provide a synthetic paint spraying device for the sealing layer of advertising boards, so as to solve the technical problem that most existing synthetic paint spraying devices for the sealing layer of advertising boards have several sets of nozzles fixed on them, which cause a lot of waste when spraying the sealing layer of small advertising boards.
[0006] The technical problem to be solved by this utility model can be achieved through the following technical solution:
[0007] A synthetic paint spraying device for sealing the advertising board includes a spraying box.
[0008] The front and rear ends of the spray box are provided with rectangular grooves. Inside the spray box, a bidirectional lead screw is rotatably mounted, and the bidirectional lead screw is located above the rectangular groove. Several sets of bidirectional threads are equally distributed on the outer side of the bidirectional lead screw. Several sets of movable seats that match the bidirectional threads are fitted on the outer side of the bidirectional lead screw. The bottom end of the movable seat is provided with a spray head. Several sets of retaining rings that match the movable seats are provided on the outer side of the bidirectional lead screw. A manifold is mounted on the outer side of the spray box. Several sets of spaced-apart branch pipes are provided at the output end of the manifold. A control valve is provided on the branch pipe. The output end of the branch pipe is connected to the spray head through a liquid infusion hose.
[0009] Preferably, the bottom of the spray box is symmetrically provided with columns at the four corners, and the bottom of the spray box is provided with a heating module.
[0010] Preferably, the top of the spray box is provided with an exhaust pipe, and a viewing window is provided on one side of the spray box.
[0011] Preferably, the front end of the spray box is symmetrically provided with a bracket, and a tension roller is rotatably arranged between the brackets, with the tension roller located below the rectangular groove.
[0012] Preferably, the front and rear ends of the spray box are symmetrically provided with brackets two, and the brackets two are located on both sides of the rectangular groove. The length of the brackets two is less than the length of the bracket one. A guide roller is rotatably arranged between the brackets two, and the guide roller is located above the tension roller.
[0013] Preferably, both ends of the tension roller and the guide roller are symmetrically provided with sliding correction sleeves, and the correction sleeves are fixed to the tension roller and the guide roller by positioning bolts.
[0014] Preferably, the front and rear inner walls of the spray box are symmetrically provided with limiting clamps, and the limiting clamps are located on both sides of the rectangular groove. The limiting clamps are slidably provided with sealing plates for sealing the rectangular groove.
[0015] Preferably, a threaded sleeve is provided on one side of the sealing plate, and a limiting groove is formed inside the threaded sleeve. A threaded rod is movably connected inside the limiting groove by a thread.
[0016] Preferably, the inner walls of the front and rear ends of the spray box are rotatably provided with a first bevel tooth, the top end of the threaded rod is provided with a second bevel tooth that meshes with the first bevel tooth, and the inner walls of the front and rear ends of the spray box are provided with a protective cover that is rotatably connected to the second bevel tooth, and the protective cover covers the first bevel tooth and the second bevel tooth.
[0017] Preferably, the input end of the manifold is provided with a connector, and the front and rear ends of the spray box are rotatably provided with a handwheel connected by bevel teeth.
[0018] The beneficial effects of this utility model are:
[0019] 1. In this utility model, the rotation of the bidirectional lead screw allows the moving seat to move in opposite directions or away from each other along the bidirectional lead screw, thereby driving the spray head to move. This enables spraying coverage of advertising boards of different widths, improving the versatility of the device. The manifold is used to centrally transport synthetic paint, and the split pipe distributes the synthetic paint to each spray head. The control valve can independently control the opening and closing of each split pipe, thereby achieving independent control of different spray heads. According to the specific size of the advertising board and the spraying requirements, the number of spray heads participating in the spraying can be flexibly adjusted to improve spraying efficiency and quality, while reducing the waste of synthetic paint.
[0020] 2. In this utility model, when the first bevel gear is rotated, the threaded rod is driven to rotate through the meshing transmission of the first bevel gear and the second bevel gear. Since the limiting clamp plate limits the sealing plate, the threaded sleeve will drive the sealing plate to move up and down along the limiting clamp plate, thereby opening or blocking the rectangular groove. During the spraying process, the sealing plate blocks the rectangular groove to prevent synthetic paint from leaking from the rectangular groove and ensure the sealing of the spraying environment. The staff can adjust the indirection between the sealing plates according to the thickness of the sealing layer of the advertising board, making the device more flexible. Attached Figure Description

Detailed Implementation
[0027] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.
[0028] like Figure 1-4 As shown, an advertising board sealing layer synthetic paint spraying device includes a spray box 1, which serves as the main container for the entire spraying process, providing a closed working environment for the spraying operation.
[0029] The front and rear ends of the spraying box 1 are both provided with rectangular grooves 6 for feeding and discharging the sealing layer of the advertising board.
[0030] The spray box 1 is equipped with a rotatable bidirectional lead screw 20, which is located above the rectangular groove 6. Several sets of equidistant bidirectional threads are formed on the outer side of the bidirectional lead screw 20. Several sets of equidistant movable seats 21, matching the bidirectional threads, are fitted onto the outer side of the bidirectional lead screw 20. A spray head 22 is located at the bottom of each movable seat 21. Several sets of retaining rings 23, matching the movable seats 21, are also provided on the outer side of the bidirectional lead screw 20. A manifold 24 is mounted on the outer side of the spray box 1. Several sets of spaced branch pipes 26 are provided at the output end of the manifold 24. A control valve 27 is installed on each branch pipe 26. The output end of the branch pipe 26 is connected to the spray head 22 via a tubing 28. The bidirectional thread design of the bidirectional lead screw 20 allows the movable seats 21 fitted onto it to move along the bidirectional lead screw 20 when the bidirectional lead screw 20 rotates. The spray heads 22 move in opposite directions, thus enabling spraying coverage of advertising boards of different widths and improving the versatility of the device. The retaining ring 23 limits the movement of the moving base 21, preventing it from shifting or colliding with each other during movement, ensuring the accuracy and stability of the spray head 22's movement. The manifold 24 centrally delivers the synthetic paint, distributing it to each spray head 22 via the branch pipe 26. The control valve 27 independently controls the opening and closing of each branch pipe 26, allowing for independent control of different spray heads 22. The number of spray heads 22 participating in the spraying can be flexibly adjusted according to the specific size of the advertising board and spraying requirements, improving spraying efficiency and quality while reducing synthetic paint waste. The infusion hose 28 ensures that the spray head 22 can continuously and stably receive synthetic paint during movement, unaffected by the movement.
[0031] In this embodiment, specifically, the bottom of the spraying box 1 is symmetrically provided with four columns 2, and the bottom of the spraying box 1 is provided with a heating module 3. The heating module includes a heating wire and a temperature detection and control module. The heating module 3 can accelerate the drying speed of the synthetic paint, improve production efficiency, and ensure the quality of the sprayed coating.
[0032] In this embodiment, specifically, the top of the spray box 1 is provided with an exhaust pipe 4, which is used to connect to an external exhaust mechanism to discharge harmful gases and excess paint mist generated during the spraying process. A viewing window 5 is provided on one side of the spray box 1, which allows the operator to observe the spraying situation inside the spray box 1 in real time and adjust the spraying parameters or handle abnormal situations in a timely manner.
[0033] In this embodiment, specifically, a first bracket 7 is symmetrically arranged at the front end of the spray box 1, and a tension roller 8 is rotatably arranged between the first brackets 7, with the tension roller 8 located below the rectangular groove 6. A second bracket 9 is symmetrically arranged at both the front and rear ends of the spray box 1, with the second bracket 9 located on both sides of the rectangular groove 6. The length of the second bracket 9 is less than the length of the first bracket 7. A guide roller 10 is rotatably arranged between the second brackets 9, with the guide roller 10 located above the tension roller 8. Sliding correction sleeves 11 are symmetrically arranged at both ends of the outer sides of the tension roller 8 and the guide roller 10, and the correction sleeves 11 are connected to the guide roller 10 by positioning bolts. The tension roller 8 and guide roller 10 are fixed together. The tension roller 8 tensions the advertising board sealing layer entering the spray box 1 to ensure that the advertising board sealing layer remains flat during the spraying process and avoids wrinkles or loosening, which would affect the spraying quality. The guide roller 10 guides the advertising board sealing layer to accurately enter the spraying area. The correction sleeve 11 can slide on the tension roller 8 and guide roller 10 and is fixed by the positioning bolt. It is used to adjust the running trajectory of the advertising board sealing layer to prevent the advertising board sealing layer from deviating during the transmission process and to ensure the accuracy of the spraying position.
[0034] In this embodiment, specifically, limiting clamps 12 are symmetrically arranged on the inner walls of the front and rear ends of the spray box 1, and the limiting clamps 12 are located on both sides of the rectangular groove 6. A sealing plate 13 for sealing the rectangular groove 6 is slidably arranged inside the limiting clamps 12. A threaded sleeve 14 is provided on one side of the sealing plate 13. A limiting groove 15 is opened inside the threaded sleeve 14. A threaded rod 16 is movably connected inside the limiting groove 15 by a thread. A first bevel tooth 17 is rotatably arranged on the inner walls of the front and rear ends of the spray box 1. A second bevel tooth 18 that meshes with the first bevel tooth 17 is provided at the top of the threaded rod 16. A protective cover 19 is rotatably connected to the second bevel tooth 18 on the inner walls of the front and rear ends of the spray box 1, and the protective cover 19 covers the first bevel tooth 17 and the second bevel tooth 18. The limiting clamps 12 provide guidance for the sliding of the sealing plate 13. The sealing plate 13 is positioned and limited to ensure that it can accurately seal the rectangular groove 6. When the first bevel gear 17 is rotated, the threaded rod 16 is driven to rotate through the meshing transmission of the first bevel gear 17 and the second bevel gear 18. Since the limiting clamp 12 limits the sealing plate 13, the threaded sleeve 14 will drive the sealing plate 13 to move up and down along the limiting clamp 12, thereby opening or sealing the rectangular groove 6. During the spraying process, the sealing plate 13 seals the rectangular groove 6 to prevent synthetic paint from leaking from the rectangular groove 6 and to ensure the sealing of the spraying environment. The staff can adjust the distance between the sealing plates 13 according to the thickness of the advertising board sealing layer, making the device more flexible. The protective cover 19 protects the first bevel gear 17 and the second bevel gear 18 to prevent external impurities from entering and affecting the transmission accuracy, while improving the safety of the device.
[0035] In this embodiment, specifically, the input end of the manifold 24 is provided with a connector 25, and the front and rear ends of the spray box 1 are rotatably provided with handwheels 29 connected to bevel gears 17. The connector 25 is used to connect to the external synthetic paint delivery pipe, so as to facilitate the introduction of synthetic paint into the manifold 24. The handwheel 29 is convenient for the operator to manually rotate the bevel gears 17, thereby controlling the movement of the sealing plate 13. The operation is simple and convenient.
[0036] The contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0037] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
