Description

Technical Field

[0001] This utility model relates to the field of paint spraying technology, specifically to a water-based paint spraying fixture. Background Technology

[0002] Water-based coatings are a type of coating made by grinding water-soluble synthetic resins as the main film-forming substance, water as a diluent, and adding appropriate amounts of pigments, fillers, and auxiliary materials. The hydrophilicity of water-soluble resins comes from their own hydrophilic groups. These hydrophilic groups not only make the polymer hydrophilic, but also endow it with many valuable properties, such as adhesion, film-forming properties, lubrication, gelling properties, chelating properties, dispersibility, flocculation, friction reduction, and thickening properties.

[0003] When existing water-based paint spraying equipment sprays boards during the conveying process, paint easily adheres to the guide rollers. If the paint is not cleaned in time, it will harden, causing protrusions on the guide rollers. This prevents the boards from being conveyed horizontally. When the boards are tilted, the water-based paint cannot be sprayed evenly on their surface. However, when cleaning the existing guide rollers, the machine needs to be stopped first, and then all the guide rollers need to be cleaned at the same time. This method will affect the spraying efficiency. Utility Model Content

[0040] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0041] Example: Please refer to Figure 1 - Figure 7 A water-based coating spraying fixture includes a base 1, a spray box 2 installed on the top of the base 1, and a spraying mechanism 3 installed inside the spray box 2. An inlet 7 is provided on the outer wall of one side of the spray box 2, and an outlet 8 is provided on the outer wall of the other side of the spray box 2. The lower edge of the inlet 7, the lower edge of the outlet 8, and the upper edge of the guide roller 5 are at the same horizontal height. The spraying range of the spraying mechanism 3 does not exceed the two ends of the guide roller 5. Roller conveyors are provided on both the left and right sides of the base 1. The roller conveyor on the left side is used to transport the board from the inlet 7 to the top of the guide roller 5. After spraying, the guide roller 5 transports the board through the outlet 8 to the top of the roller conveyor on the right side.

[0042] Also includes:

[0043] The conveying mechanism is installed inside the base 1. The conveying mechanism includes multiple drive shafts 4 disposed inside the base 1 and guide rollers 5 fixedly sleeved on the outside of the drive shafts 4.

[0044] By controlling the drive mechanism to drive each transmission shaft 4 to rotate synchronously in the same direction, and then drive each guide roller 5 to rotate synchronously, the plate is conveyed from left to right. During the conveying process, the plate is sprayed by the spraying mechanism 3.

[0045] An independent lifting mechanism is installed on the base 1 to drive the lifting of a single guide roller 5. The independent lifting mechanism includes lifting blocks 9 rotatably connected to both ends of the transmission shaft 4, sliding grooves 10 respectively opened on the inner walls of the front and back sides of the base 1, and a cylinder 11 installed on the top of the lifting blocks 9. The sliding groove on the back side penetrates the outer wall of the base 1. The lifting blocks 9 slide in the inside of the sliding grooves 10, and one end of the lifting blocks 9 on the back side extends to the outside of the base 1. The cylinder 11 is installed on the outer wall of the spray box 2.

[0046] By controlling the extension of cylinder 11 one by one, the extension of cylinder 11 drives the lifting block 9 to move downward along the inner wall of the slide groove 10, thereby driving the corresponding single drive shaft 4 and its external guide roller 5 to move downward. After the outer wall of the downward-moving guide roller 5 is cleaned, the control cylinder 11 drives the lifting block 9 to move upward and reset, thereby driving the cleaned guide roller 5 to move upward and reset. Then, the control cylinder 11 drives the next guide roller 5 to move downward for cleaning. This cycle is repeated to clean multiple guide rollers 5 in sequence. By cleaning the guide rollers 5 one by one, the purpose of cleaning the guide rollers 5 without stopping the machine is achieved.

[0047] A drive mechanism is installed on the back of the spray box 2 to drive the guide roller 5 to rotate. The drive mechanism includes a housing 12 installed on the back of the spray box 2, multiple transmission components installed inside the housing 12, and a control component for driving the multiple transmission components to operate. The transmission components are connected to the transmission shaft 4. One end of the transmission shaft 4 passes through one of the lifting blocks 9. The transmission components include a driven shaft 13 rotatably connected inside the housing 12, a linkage sleeve 14 slidably sleeved outside the driven shaft 13, and a worm gear 15 fixedly sleeved outside the driven shaft 13. Both the outer side of the linkage sleeve 14 and the outer side of the transmission shaft 4 are fixedly fitted with bevel gears 16, which mesh with each other. A connecting block 17 is also rotatably fitted onto the outer side of the linkage sleeve 14, and the connecting block 17 is also rotatably fitted onto the outer side of the transmission shaft 4. The control assembly includes a first motor 18 mounted on the outer wall of the housing 12 and a drive shaft 19 rotatably connected inside the housing 12. The output end of the first motor 18 is fixedly connected to one end of the drive shaft 19. Multiple worm gears 20 are fixedly fitted onto the outer side of the drive shaft 19, and the worm gears 20 mesh with worm wheels 15.

[0048] By controlling the first motor 18 to drive the drive shaft 19 to rotate, multiple worm gears 20 rotate synchronously. Through the meshing action between the worm gears 20 and the worm wheel 15, the driven shaft 13 is driven to rotate, and the linkage sleeve 14 rotates synchronously. Through the meshing action between the two bevel gears 16, the transmission shaft 4 is driven to rotate, which in turn drives the guide roller 5 to rotate.

[0049] As the drive shaft 4 and guide roller 5 move downward, the connecting block 17 drives the linkage sleeve 14 to slide synchronously downward along the outer wall of the driven shaft 13, so that the two bevel gears 16 always remain in mesh. In other words, the guide roller 5 also keeps rotating during the cleaning process after it descends.

[0050] An independent cleaning mechanism is installed inside the base 1. The independent cleaning mechanism includes multiple scraper rings 6 disposed inside the base 1 and a displacement assembly for driving the multiple scraper rings 6 to move. The displacement assembly includes a lead screw 21 rotatably connected inside the base 1, a slide bar 22 screwed to the outside of the lead screw 21, and a second motor 23 installed on the front of the base 1. The output end of the second motor 23 is fixedly connected to one end of the lead screw 21. A guide rod 24 is fixedly connected inside the base 1, and the slide bar 22 is also slidably sleeved on the outside of the guide rod 24. The top of the scraper rings 6 is provided with a mating groove 25, and multiple scraper rings 6 are sequentially fixed together along the length of the slide bar 22. The multiple scraper rings 6 are respectively located directly below multiple drive shafts 4.

[0051] After the drive shaft 4 and guide roller 5 move down, the drive shaft 4 passes through the docking groove 25 and enters the scraper ring 6. The inner diameter of the scraper ring 6 is the same as the outer diameter of the guide roller 5. By controlling the second motor 23 to drive the lead screw 21 to rotate clockwise, the slide bar 22 moves forward along the outer wall of the guide rod 24, and the scraper ring 6 moves forward synchronously. The scraper ring 6 will then move along the outer wall of the guide roller 5, and work with the guide roller 5 during the rotation process to scrape off the paint on the outer wall of the guide roller 5. This avoids the problem that the paint on the outside of the guide roller 5 will harden due to not being cleaned in time, which will prevent the board from being transported horizontally. It also avoids the problem that the spraying quality will be affected by the tilt of the board.

[0052] By controlling the second motor 23 to drive the lead screw 21 to rotate counterclockwise, the slide bar 22 can be driven to move backward along the outer wall of the guide rod 24.

[0053] The inner wall of the bottom of the base 1 has a funnel-shaped structure, and a discharge pipe 26 is installed at the bottom of the base 1;

[0054] The scraped paint flows down the inner wall of the bottom of the base 1 and is eventually discharged through the discharge pipe 26 for collection.
