Description

Technical Field

[0001] This utility model relates to the field of dust removal technology for coating machines, specifically a dust removal mechanism for a height-adjustable coating machine. Background Technology

[0002] A coating machine is a device that applies adhesives, coatings, or inks with specific functions to the surface of substrates such as cloth, paper, or plastic films. It is widely used in industries such as electronics, medical, new energy, and textiles. Before the coating process, if the substrate surface is contaminated with dust, fibers, or other impurities, it will directly affect the uniformity of the coating, its adhesion, and the quality of the final product. Therefore, the substrate must be cleaned by an efficient dust removal system before entering the coating head to ensure the effectiveness of subsequent coating processes.

[0003] In the existing technology, the dust removal mechanism of the coating machine is usually equipped with a filtration system to collect dust and keep the air passage unobstructed. However, the filter elements in the filtration system need to be cleaned or replaced after a period of use. This maintenance process will cause the entire coating production line to be temporarily interrupted, affecting the production efficiency and continuous operation capability of the equipment.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This height-adjustable dust removal mechanism for a coating machine, through the cooperation of a switching valve, parallel-arranged pipes, and a filter chamber separated by a partition, enables the switching of the working states of the two filter chambers.

[0024] 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.

[0025] like Figure 1-4 As shown, this utility model provides a technical solution:

[0026] A height-adjustable dust removal mechanism for a coating machine includes a first bracket 1 and a second bracket 2, with a dust collection box 3 and a filter box 4 fixedly connected to the top of the first bracket 1 and the second bracket 2, respectively; a dust removal mechanism is disposed inside the upper and lower ends of the dust collection box 3, and includes a dust removal channel 6 extending through the middle of the dust collection box 3, and suction pipes 7 respectively disposed inside the upper and lower ends of the dust removal channel 6, with the suction inlets of the two suction pipes 7 located on opposite sides of each other; a transmission box 5 is fixedly connected to the outside of the dust collection box 3 on the side away from the filter box 4, and is used for transmission. The dust collection box 5 is equipped with an adjustment mechanism, which is connected to the dust removal mechanism. The adjustment mechanism includes a double-acting lead screw 8 rotatably connected to the inside of the transmission box 5 via bearings, and a motor 9 fixedly connected to the top of the transmission box 5. The output shaft of the motor 9 is fixedly connected to the double-acting lead screw 8. Both ends of the double-acting lead screw 8 are threaded with sliding nuts 10. The left end of the suction pipe 7 is fixedly connected to the sliding nut 10. Both the left and right sides of the dust collection box 3 have clearance grooves 11. The adjustment mechanism also includes a pipe 12 fixedly connected to the right end of the suction pipe 7, and a fixed... A guide block 13 is fixedly connected to the outer periphery of pipe 12. A vertical guide rod 14 is fixedly connected to the inside of the right side of the dust collector 3. The guide block 13 and the guide rod 14 are slidably connected. A filter mechanism is set inside the filter box 4 and cooperates with the dust collection mechanism. The filter mechanism includes a three-way pipe 15 fixedly connected between the dust collector 3 and the filter box 4. The two input ends of the three-way pipe 15 are fixedly connected to the two pipes 12 through corrugated pipes 16 respectively. A switching valve 17 is fixedly connected to the output end of the three-way pipe 15. A pair of valves are arranged side by side in the middle of the inner side of the filter box 4. Two partitions 18 are fixedly connected, and pipes 19 are fixedly connected in the middle of the two partitions 18. The input ends of the two pipes 19 are fixedly connected to the two input ends of the switching valve 17. Pipes 20 are fixedly connected to both sides of the filter box 4. Pull-out grooves 21 are opened at both ends on the side of the filter box 4 away from the dust collector 3. Filter plates 22 can be pulled out between the pull-out grooves 21 and the filter box 4. A fan 23 is fixedly connected to the middle of the bottom of the filter box 4. The input end of the fan 23 is fixedly connected to the output end of the two pipes 20 through a three-way connector.

[0027] In this embodiment, the switching valve 17, the parallel-arranged pipes 19, and the filter chambers separated by the partition 18 are used in conjunction to achieve the switching of the working state of the two filter chambers. This allows the dust removal system to continue operating through the other filter chamber while the filter plate 22 in one filter chamber is being cleaned or replaced. This solves the problem of having to stop for maintenance due to the replacement of the filter plate 22 in the prior art, and ensures the continuity of production.

[0028] Furthermore, by using the motor 9, the bidirectional lead screw 8 and the sliding nut 10 together, the two suction pipes 7 are driven to move synchronously towards or away from each other, and their movement trajectory is maintained by the sliding connection between the guide block 13 and the guide rod 14. This makes the height of the suction pipes 7 adjustable, so that they can adapt to fabrics of different thicknesses and improve the versatility of the dust removal mechanism.

[0029] Working principle: When the height of the suction pipe 7 needs to be adjusted, the motor 9 is started. The motor 9 starts and drives the bidirectional lead screw 8 to rotate, driving the two sliding nuts 10 to move towards or away from each other in the transmission box 5. This causes the two suction pipes 7, which are fixed on the sliding nuts 10, to move synchronously closer or further away in the vertical direction to adapt to fabrics of different thicknesses. When the suction pipe 7 moves, the pipe 12 fixed at its right end moves accordingly. The guide block 13 on the pipe 12 slides along the vertically fixed guide rod 14 to maintain a stable movement trajectory. During dust removal, the fan 23 runs continuously to generate negative pressure, so that the dust on the upper and lower surfaces of the fabric running in the dust removal channel 6 is captured by the suction inlets of the two suction pipes 7. The dust-laden airflow passes through the pipe 12 in sequence. The corrugated pipe 16 and the tee pipe 15 are guided by the switching valve 17 and sprayed into one of the working pipes 19. Then, the air enters a corresponding filter chamber formed by the partition 18. At this time, the filter plate 22 in the chamber filters the airflow. Dust is trapped and clean air is discharged by the fan 23 through the pipe 20 and the tee joint. When the filter plate 22 needs to be cleaned, the switching valve 17 is operated to reverse the direction, so that the dust-laden airflow enters another pipe 19 and is filtered by another filter chamber and its internal filter plate 22. The previously working filter chamber is isolated and empty. At this time, the dust-laden filter plate 22 can be pulled out for cleaning or replacement through the pull-out groove 21, so as to achieve continuous operation without stopping the machine.
