Technical Field
[0001] This utility model relates to the field of paperboard spraying technology, specifically to a stain-resistant coating spraying device for paperboard production. Background Technology
[0002] Paperboard, also known as cardboard, is a thick sheet of paper made from various pulps, composed of interwoven fibers. During the paperboard production process, it often requires spray coating. Spray coating is a coating method that uses a spray gun or disc atomizer to disperse the material into uniform and fine droplets using pressure or centrifugal force, which are then applied to the surface of the object being coated.
[0003] Traditionally, frontline operators directly spray the surface of cardboard with hand-held spray guns. Manual spraying is inefficient and uneven, increasing the number of defective products. Therefore, an anti-fouling coating spraying device for cardboard production is proposed. Utility Model Content

[0019] 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.
[0020] Please see Figures 1-5 This utility model provides a technical solution, including a device housing 1. A first cavity 2 and a second cavity 3 are respectively opened on one side of the device housing 1. A rotary cylinder 4 is connected to the bottom of the second cavity 3. A connecting frame 5 is connected to the top of the rotary cylinder 4. A hydraulic cylinder 6 is connected to the surface of the rotary cylinder 4 and is connected to the inner wall of the second cavity 3. The telescopic end of the connecting frame 5 extends into the first cavity 2 and is connected to a worktable 7. Two sets of clamping devices 8 are connected to the top of the worktable 7. Two sets of electric slide rails 9 are connected to the top of the first cavity 2 and are arranged in a cross shape. A sliding block 91 is slidably arranged on the surface of the electric slide rail 9. A spraying mechanism 10 is connected to the bottom of the sliding block 91. A storage box 11 is connected to one side of the device housing 1.
[0021] The clamping device 8 includes a column 81 connected to the top of the worktable 7. A threaded rod 82 is rotatably mounted inside the column 81. One end of the threaded rod 82 extends outside the column 81 and is connected to a micro motor 83. A slide rail 84 is formed on the surface of the column 81. A telescopic rod 85 is threaded onto the surface of the threaded rod 82 and slidably mounted within the slide rail 84. A clamping plate 86 is connected to one end of the telescopic rod 85. The clamping device 8 uses the micro motor 83 to drive the threaded rod 82 to rotate inside the column 81. This design allows the telescopic rod 85 to move precisely linearly along the surface of the threaded rod 82. Because the telescopic rod 85 is simultaneously slidably mounted within the slide rail 84 on the surface of the column 81, its movement trajectory is more stable, resulting in higher clamping accuracy.
[0022] The spraying mechanism 10 includes a hollow connecting block 101 connected to the bottom of the sliding block 91. Four sets of spray nozzles 102 are connected to the bottom of the hollow connecting block 101. A corrugated pipe 103 is connected to one side of the hollow connecting block 101. A material conveying pipe 104 is connected to one end of the corrugated pipe 103. A pressure boosting box 105 is connected to the other end of the material conveying pipe 104. The pressure boosting box 105 is connected to the top of the device housing 1 and a connecting pipe 106 is connected to one side. The other end of the connecting pipe 106 is connected to the inside of the storage tank 11. The function of the corrugated pipe 103 is to ensure that the spraying mechanism 10 can maintain a continuous connection with the material conveying pipe 104 when it moves, thereby ensuring a stable supply of paint and increasing the flexibility of the spraying mechanism, enabling it to perform spraying operations at different positions and angles.
[0023] A transparent scale plate 111 is connected to one side of the storage tank 11, and a feeding port 112 is connected to the top of the storage tank 11. A sealing cap 113 is slidably installed on the top of the feeding port 112. A sealing element 114 is installed at the connection between the connecting pipe 106 and the storage tank 11. The function of the transparent scale plate 111 is to allow the operator to intuitively observe the remaining amount of paint in the storage tank 11. The setting of the feeding port 112 makes it simple and quick to add paint to the storage tank 11. The design of the sealing cap 113 helps to prevent the paint from evaporating at the feeding port 112.
[0024] An exhaust gas box 12 is connected to one side of the outer casing 1 of the device, and one side of the exhaust gas box 12 extends into the first cavity 2. An activated carbon plate 13 is connected to one side of the interior of the exhaust gas box 12, and an exhaust fan 14 is connected to one side of the exhaust gas box 12. The function of the exhaust fan 14 is to ensure that the harmful gases in the exhaust gas box 12 can be discharged in a timely manner.
[0025] A door panel 15 is hinged to one side of both the first cavity 2 and the second cavity 3. A handle 16 is connected to one side of the door panel 15. The purpose of the handle 16 is to facilitate daily equipment inspection, maintenance and replacement operations, and to ensure the normal operation of the equipment.
[0026] An observation window 17 is provided on the surface of the door panel 15 on one side of the first cavity 2. Its function is to help monitor the operating status of the equipment, the application of coatings, or the effect of exhaust gas treatment in the cavity in real time, so as to discover and deal with potential problems in a timely manner.
[0027] Working principle: Pulling handle 16 opens door panel 15, then the cardboard is placed on workbench 7. Turning on micro motor 83 drives threaded rod 82 to rotate, thereby causing telescopic rod 85 to slide within slide rail 84, opening and closing clamping plate 86, thus clamping or releasing the cardboard. The coordinated action of rotary cylinder 4 and hydraulic cylinder 6 allows workbench 7 to rotate and rise within first cavity 2, adjusting the position and angle of the cardboard to adapt to different spraying requirements. Paint is stored in storage tank 11, and the remaining amount can be easily observed through transparent scale plate 111. During spraying, paint is transferred through the connection... Pipe 106 is conveyed to pressurization box 105, which pressurizes the paint so that it can be smoothly conveyed to spraying mechanism 10 through conveying pipe 104 and corrugated pipe 103. Under high pressure, the paint is atomized and sprayed evenly onto the cardboard surface through nozzle 102. The sliding block 91 slides on electric slide rail 9 so that spraying mechanism 10 can move along a predetermined path to achieve comprehensive spraying. During the spraying process, the generated exhaust gas is collected in exhaust gas box 12. Activated carbon plate 13 inside exhaust gas box 12 adsorbs and purifies the exhaust gas, and exhaust fan 14 is responsible for discharging the treated exhaust gas from the device.
