Description

Technical Field

[0001] This utility model relates to the field of spraying technology, specifically to a surface spraying device for mesh fabric processing. Background Technology

[0002] Mesh fabric, also known as woven fabric, can be categorized into woven mesh fabric, knitted mesh fabric, and non-woven mesh fabric. Woven mesh fabric can be either white-woven or yarn-dyed, while knitted mesh fabric includes weft-knitted mesh fabric and warp-knitted mesh fabric.

[0003] For example, a coating device for mesh fabric processing, as disclosed in announcement number CN221288427U, has a smoothing roller between the spraying component and the drying component. The two ends of the smoothing roller are fixed to the two sides of the processing frame. The bottom of the smoothing roller has a movable cavity, and multiple elastic elements are evenly distributed on the top wall of the movable cavity. A pressure plate is movably installed at the bottom of the movable cavity. The bottom of the pressure plate is in contact with the surface of the mesh fabric. When the mesh fabric passes through the smoothing roller, the pressure plate is always in contact with the surface of the mesh fabric under the elastic force of the elastic elements. The coating is fully applied to the surface of the mesh fabric by the obstruction of the pressure plate, which improves the uniformity of the coating to a certain extent. Then, the heating fan blades are driven by the drive component to dry the coating on the surface of the mesh fabric. However, there is a lot of floating dust and some impurities in the workshop, which makes it easy for a lot of impurities to adhere to the surface of the mesh fabric before spraying, thus affecting the subsequent spraying effect.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the surface spraying device for mesh processing can effectively shake the mesh before spraying, thereby effectively removing impurities and dust, allowing the coating to better penetrate into these gaps during spraying. Simultaneously, the spraying pipe can be oscillated during the dyeing process to change the spray angle and path of the coating, resulting in a more uniform distribution of the coating on the mesh surface. Specific details are as follows:

[0014] 1. The device is equipped with a half-gear and a rack. The half-gear is driven to rotate by a rotating shaft, causing it to intermittently mesh with the rack. This causes the rack to compress the spring and simultaneously move the second magnet. The second magnet then intermittently faces the first magnet, and the repulsive force pushes the moving block to move. The moving block compresses the second spring from top to bottom, causing it to contract. Then, when the second magnet separates, the elastic force of the first magnet and the second spring pushes the moving block back to its original position. This process is repeated to shake the mesh fabric, removing impurities and dust from its surface and preventing these contaminants from affecting the adhesion and uniform distribution of the coating.

[0015] 2. It is equipped with an air bladder and a horizontal plate. When the rack moves, it drives the piston rod to move, which in turn pushes the piston plate to slide inside the piston cylinder. This delivers the gas stored in the piston cylinder to the air bladder, causing the air bladder to inflate. This pushes the horizontal plate up and down along the fixed rod, and the horizontal plate drives the spray pipe to rotate, increasing the spraying range of the spray pipe.

[0022] 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.

[0023] Example 1: Please refer to Figures 1-5 As shown, this utility model provides a technical solution: a surface spraying device for mesh fabric processing, comprising: a box body 1, two first conveying rollers 2 symmetrically and rotatably mounted on the upper end of the box body 1, and a drive motor 3 fixedly mounted on the side wall of the box body 1.

[0024] This technical solution utilizes the setting of drive motor 3. In use, the mesh is passed through the first conveying roller 2, the contact roller 9, the guide roller 12, the second conveying roller 6 and the third pulley 20 in sequence. Then, drive motor 3 is started, which drives the second pulley 503 to rotate, thereby moving the mesh for spraying operation.

[0025] Example 2: The technical content disclosed in this example is an improvement based on Example 1. Existing workshops often contain a large amount of floating dust and impurities, causing the surface of the mesh fabric to easily accumulate impurities before spraying, thus affecting the subsequent spraying effect. This technical solution addresses this issue. Figure 1 and Figure 2As shown, a cleaning component of a spraying device is disclosed. Two rectangular grooves 7 are formed on the inner wall of the opposite side of the housing 1. A slider 8 is slidably disposed within the rectangular grooves 7, and an abutment roller 9 is rotatably mounted on the slider 8. A vertical groove 10 is formed on the inner wall of the housing 1 below the rectangular grooves 7. A moving block 11 is disposed within the vertical groove 10, and a guide roller 12 is rotatably mounted on the moving block 11. A bracket 14 is fixedly connected to the moving block 11, and a first magnet 15 is fixedly connected to the bottom end of the bracket 14. The shaft end of a second conveying roller 6 extends through the housing 1 and is fixedly connected to the output end of a drive motor 3. A first pulley 1 is fixedly nested and connected to both the shaft end of the first conveying roller 6 and the outer wall of the output end of the drive motor 3. 3. The two first conveyor rollers 2 are connected by a belt. The shaft end of the third conveyor roller 19 extends through the box 1 and the extended end of the third conveyor roller 19 is fixedly connected to the third pulley 20. The third pulley 20, the second pulley 503 and the first pulley 13 are connected by a conveyor belt. The side wall of the slider 8 is fixedly connected to the first spring 17, and the end of the first spring 17 away from the slider 8 is fixedly connected to the inner wall of the rectangular groove 7. The top of the moving block 11 is fixedly connected to the second spring 18, and the end of the second spring 18 away from the moving block 11 is fixedly connected to the inner wall of the vertical groove 10. A collection box is provided in the box 1 below the moving block 11, and a fan is provided in the collection box.

[0026] In this technical solution, as follows Figure 2 As shown, by using the arrangement of the first magnet 15 and the second magnet 508, the first magnet 15 and the second magnet 508 generate a repulsive force on each other, which pushes the moving block 11 to move up and down repeatedly, thereby causing the mesh to shake, removing impurities and dust, and improving the quality of the coating.

[0027] Its adoption is as follows Figure 1 and Figure 2The technical solution shown is as follows: Firstly, during use, the drive motor 3 drives the second conveyor roller 6 and the first pulley 13 to rotate synchronously. The first pulley 13 drives the second pulley 503 and the third pulley 20 to rotate via a belt and a conveyor belt, which in turn drives the first conveyor roller 2, the rotating shaft 501, and the third conveyor roller 19 to rotate synchronously. When the rotating shaft 501 rotates, it drives the half-gear 502 to rotate. The half-gear 502 intermittently meshes with the rack 507 during rotation, thus moving the rack 507. The rack 507 compresses the compression spring 16, causing it to contract and simultaneously move the second magnet 508. This creates a repulsive force between the second magnet 508 and the first magnet 15, pushing the moving block. 11 slides upward along the vertical groove 10, compressing the second spring 18 to contract. At this time, the mesh fabric relaxes, and the contracted first spring 17 pushes the slider 8 to slide along the rectangular groove 7, thereby driving the contact roller 9 to move to both sides to compress the mesh fabric. Then, after the half gear 502 separates from the rack 507, the compression spring 16 pushes the rack 507 to reset. At this time, the first magnet 15 and the second magnet 508 separate, and the second spring 18 pushes the moving block 11 to reset, causing the moving block 11 to drive the guide roller 12 to move downward. This process is repeated to make the mesh fabric shake, thereby automatically shaking off impurities and dust on the surface of the mesh fabric. At the same time, the collection box at the bottom of the box 1 collects the shaken impurities.

[0028] Example 3: The technical content disclosed in this example is a further improvement based on Examples 1 and 2 above. Because the existing method cannot adjust the spraying angle, the coating may not evenly cover the mesh surface, resulting in inconsistent coating thickness and affecting the overall appearance and quality of the product. To further solve this technical problem, this technical solution is as follows... Figures 3-5As shown, an angle adjustment component of a spraying device is disclosed. A spraying box 4 is fixedly installed inside a housing 1. A spraying mechanism 5 is mounted on the spraying box 4. A second conveying roller 6 is rotatably mounted inside the housing 1 above the spraying box 4, and a third conveying roller 19 is also rotatably mounted inside the spraying box 4. The spraying mechanism 5 includes a rotating shaft 501, a half-gear 502, a second pulley 503, a piston cylinder 504, a piston plate 505, a piston rod 506, a rack 507, and a second magnet 508. The rotating shaft 501 is rotatably mounted inside the housing 1, and a half-gear 502 is fixedly nested and connected to the outside of the rotating shaft 501. One end of the piston cylinder 504 extends through the housing 1 and is fixedly connected to the second pulley 503. The piston cylinder 504 is fixedly installed on the side wall of the spraying box 4. A piston plate 505 is slidably installed inside the spraying box 4. A piston rod 506 is fixedly connected to the side wall of the piston plate 505. One end of the piston rod 506 extends through the piston cylinder 504 and is fixedly connected to the rack 507. A second magnet 508 is fixedly connected to the rack 507. The spraying mechanism 5 also includes a fixed rod 509, an airbag 510, a horizontal plate 511, a through hole 512, a protrusion 513, a connecting shaft 514, a drying plate 515, a spiral groove 516, and a spraying pipe 517. 09 is fixedly installed on the inner wall of the spray box 4. An airbag 510 is sleeved on the outer side of the fixing rod 509. A horizontal plate 511 is slidably sleeved on the outer side of the fixing rod 509 above the airbag 510. A through hole 512 is opened on the horizontal plate 511. A protrusion 513 is fixedly installed on the inner wall of the through hole 512. A connecting shaft 514 is set in the through hole 512. A drying plate 515 is fixedly connected to the top of the connecting shaft 514. A spiral groove 516 is opened on the connecting shaft 514. A side wall movable spray pipe 517 is rotatably installed in the spray box 4 on the side of the horizontal plate 511. A piston rod 506 is slidably connected to a piston cylinder 504. The rack 507 on the side meshes with the half gear 502. A compression spring 16 is connected between the rack 507 and the spray box 4. The rack 507 and the spray box 4 form an elastic telescopic structure through the compression spring 16. The second magnet 508 corresponds to the first magnet 15. The side of the second magnet 508 that is opposite to the first magnet 15 has the same magnetic pole. The air bag 510 is connected to the air outlet of the piston cylinder 504 through a pipe. The end of the protrusion 513 away from the horizontal plate 511 extends into the spiral groove 516. The protrusion 513 and the spiral groove 516 are slidably connected. The horizontal plate 511 is rotatably connected to the spray pipe 517.

[0029] In this technical solution, as follows Figure 4 As shown, by using the horizontal plate 511 and the protruding block 513, the horizontal plate 511 moves and drives the protruding block 513 to move synchronously. Then, the protruding block 513 slides along the spiral groove 516, thereby driving the connecting shaft 514 and the drying plate 515 to rotate. This allows the hot air blown out by the hot air blower to be evenly distributed on the surface of the mesh, avoiding the problem of local overheating or insufficient drying, and enhancing the uniformity of hot airflow and drying efficiency.

[0030] Its adoption is as follows Figures 3-5 The technical solution shown first connects the drying plate 515 to an external hot air blower, and simultaneously connects the spray pipe 517 to an infusion pipe. When the rack 507 moves, the rack 507 drives the piston rod 506 to move. The piston rod 506 pushes the piston plate 505 to slide inside the piston cylinder 504, transporting the gas stored in the piston cylinder 504 to the airbag 510 through the pipe, causing the airbag 510 to inflate. This, in turn, pushes the horizontal plate 511 to slide along the fixed rod 509. The horizontal plate 511 pulls the spray pipe 517 to rotate, thereby adjusting the spraying angle of the spray pipe 517. At the same time, the horizontal plate 511 drives the protrusion 513 to slide along the spiral groove 516, causing the connecting shaft 514 to drive the drying plate 515 to rotate. The hot air blown out by the hot air blower is sprayed out from the nozzle on the drying plate 515, thereby evenly blowing the hot airflow onto the surface of the mesh fabric to dry the coating on the surface of the mesh fabric.

[0031] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
