[0001] This utility model relates to the field of chemical production technology, specifically to a centralized dust collection device for coating processing. Background Technology

[0002] Paint is a viscous liquid that is applied to the surface of an object to be protected or decorated, and forms a continuous film that adheres firmly to the object. It is usually based on resin, oil or emulsion, with or without pigments and fillers, and with appropriate additives, and is prepared with organic solvents or water. During the paint production process, some raw materials are released into the air and need to be collected by collection devices to achieve clean production.

[0003] According to a public notice (Announcement No.: CN222985199U) of a dust and volatile organic compound collection device for a coating production line, the above application includes a support frame. A collection box and a dual-shaft motor are fixedly connected to the upper and lower sides of the middle of the support frame, respectively. An air pump is fixedly connected to one side of the middle of the support frame. Reciprocating screws are provided on both sides of the support frame. A purification mechanism is provided in the center of the opposite side of the collection box and the air pump.

[0004] However, in actual use, the suction pipes of the above-mentioned collection devices are all at the same angle, which means that their suction ports are fixed in the same direction and height, and cannot cover pollution sources at different heights or directions, resulting in some areas of dust not being effectively collected and creating dead corners; in view of this, we propose a centralized dust collection device for paint processing. Summary of the Invention

[0005] The purpose of this invention is to provide a centralized dust collection device for coating processing, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a centralized dust collection device for coating processing, comprising a frame, a collection component disposed on the top end face of the frame, and a driving component disposed on the inner top surface of the frame, the driving component comprising:

[0007] A dual-axis motor, wherein the output end of the dual-axis motor is fixedly connected to a rotating shaft, and a belt is provided on the side wall of the rotating shaft;

[0011] Preferably, the dual-axis motor is fixedly connected to the inner top surface of the frame, a pulley is fixedly connected to the side wall of the rotating shaft, the pulley is connected to a belt drive, and a second pulley is fixedly connected to the side wall of the reciprocating screw, the second pulley is connected to a belt drive.

[0012] Preferably, the side wall of the frame is fixedly connected to a guide rail, and the movable frame is slidably connected to the inner wall of the guide rail, so that the movable frame can only move longitudinally.

[0013] Preferably, the reciprocating screw is rotatably connected to the frame, the half gear meshes with the gear groove on the inner wall of the movable frame, and the slider is slidably connected to the inner top surface of the frame. The rotation of the reciprocating screw causes the slider to move laterally back and forth along the inner top surface of the frame.

[0014] Preferably, the connecting rod is fixedly connected to the outer wall of the suction pipe, the connecting rod is movably connected to the inner wall of the guide frame, a guide block is fixedly connected to the outer wall of the frame, the limiting rod is slidably connected to the inner wall of the guide block, and the limiting rod is movably connected to the interior of the limiting frame.

[0016] Compared with the prior art, the present invention provides a centralized dust collection device for coating processing, which has the following beneficial effects:

[0017] 1. This paint processing dust collection device, through a set drive component, has two sets of suction pipes moving laterally in an alternating reciprocating motion. This means that the suction pipes are no longer fixed in a certain position or angle, but move laterally with the slider, thereby covering a larger area of ​​the pollution source and improving collection efficiency. While moving laterally in a reciprocating motion, the suction pipes also swing longitudinally. The longitudinally swinging suction pipes can actively sweep over areas that may form dead corners, and can more comprehensively cover the pollution source, especially areas of dust or gas with uneven distribution, thus expanding the collection range and improving collection efficiency.

[0018] 2. This coating processing dust collection device uses spur gears and teeth to make the suction pipe rotate around the connecting rod axis, thus forming a fan-like cleaning path with a wider coverage and reduced missed suction. The rotating suction port can continuously change the suction angle, which changes the direction of the airflow impact, which is conducive to disturbing the deposited dust and realizing the adsorption path at different angles. It can more effectively capture pollutants floating in the space or in corner areas. Attached Figure Description

[0027] like Figures 1-7 As shown, this utility model provides a technical solution: a centralized dust collection device for coating processing, including a frame 1, a collection component 2 is provided on the top end face of the frame 1, and a drive component 3 is provided on the inner top face of the frame 1. The drive component 3 includes a dual-axis motor 301, a rotating shaft 302, a reciprocating lead screw 303, a belt 304, a movable frame 305, a limiting frame 306, a guide frame 307, a limiting rod 308, a guide block 309, a half gear 310, a connecting rod 311, a slider 312, and a hinge block 313.

[0028] In one embodiment of this utility model, a dual-axis motor 301 is fixedly connected to the inner top surface of the frame 1. A rotating shaft 302 is fixedly connected to the output end of the dual-axis motor 301. A belt 304 is provided on the side wall of the rotating shaft 302. A pulley is fixedly connected to the side wall of the rotating shaft 302. The pulley is connected to the belt 304 for transmission. A gear groove is provided on the inner wall of the movable frame 305. A limit frame 306 is fixedly connected to the side wall of the movable frame 305. A guide rail 4 is fixedly connected to the side wall of the frame 1. The movable frame 305 is slidably connected to the inner wall of the guide rail 4. The guide rail 4 allows the movable frame 305 to move only longitudinally.

[0029] A reciprocating screw 303 is rotatably connected to the frame 1. A pulley 2 is fixedly connected to the side wall of the reciprocating screw 303, and the pulley 2 is driven by a belt 304. A half gear 310 is fixedly connected to the side wall of the reciprocating screw 303, and a slider 312 is driven by the side wall of the reciprocating screw 303. The half gear 310 meshes with a gear groove on the inner wall of the movable frame 305. The slider 312 is slidably connected to the inner top surface of the frame 1. Rotation of the reciprocating screw 303 causes the slider 312 to move laterally back and forth along the inner top surface of the frame 1. A hinge block 313 is hinged to the bottom of 12. The hinge block 313 is sleeved with the connecting rod 311. A guide frame 307 is provided on the outer wall of the connecting rod 311. Limiting rods 308 are fixedly connected to both ends of the guide frame 307. The connecting rod 311 is fixedly connected to the outer wall of the suction pipe 204. The connecting rod 311 is movably connected to the inner wall of the guide frame 307. A guide block 309 is fixedly connected to the outer wall of the frame 1. The limiting rod 308 is slidably connected to the inner wall of the guide block 309. The limiting rod 308 is movably connected to the inside of the limiting frame 306.

[0030] The collection component 2 includes an air extractor 201 fixedly connected to the top end face of the frame 1. The input end of the air extractor 201 is fixedly connected to a collection box 202. A flexible tube 203 is fixedly connected to the side wall of the collection box 202. A suction tube 204 is fixedly connected to the end face of the flexible tube 203.

[0031] A dustproof plate is fixedly connected to the outer wall of the frame 1. The dustproof plate shields the reciprocating lead screw 303 to prevent dust from adhering to the reciprocating lead screw 303. A dust cover is fixedly connected to the outer wall of the frame 1. The dust cover shields the belt 304, the limit frame 306 and the half gear 310 to prevent dust from adhering to the gear and conveyor belt structure, thereby affecting the transmission part of the device.

[0032] The vacuum pump 201 draws in air, causing it to be drawn in through the suction pipe 204. Dust in the air is drawn in through the flexible pipe 203 and enters the collection box 202. A filter screen is installed between the collection box 202 and the vacuum pump 201. The dust is trapped by the filter screen and retained in the collection box 202. Clean air is discharged through the output end of the vacuum pump 201.

[0033] The dual-axis motor 301 drives the rotating shaft 302 to rotate, which in turn drives the reciprocating screw 303 to rotate via the belt 304. This further causes the slider 312 to move laterally back and forth along the inner top surface of the frame 1. The slider 312 drives the suction pipe 204 to move laterally back and forth. The two sets of suction pipes 204 move laterally back and forth alternately, so that the suction pipes 204 are no longer fixed at a certain position or angle, but move laterally with the slider 312, thereby covering a larger area of ​​pollution sources and improving collection efficiency.

[0034] The reciprocating screw 303 rotates, driving the half gear 310 to rotate, causing the movable frame 305 to reciprocate longitudinally. The longitudinal reciprocating motion of the movable frame 305 and the limiting frame 306 drives the limiting rod 308 to move longitudinally. The limiting rod 308 slides within the guide block 309. The limiting rod 308 and the guide frame 307 drive the connecting rod 311 to move longitudinally, thereby causing the suction pipe 204 to swing longitudinally while reciprocating laterally. The longitudinally swinging suction pipe 204 can actively sweep through areas that may form dead corners, and can more comprehensively cover pollution sources, especially areas of dust or gas with uneven distribution, expanding the collection range and improving collection efficiency.

[0035] In addition, teeth 6 are fixedly connected to the inner wall of the guide frame 307, and spur gears 5 are fixedly connected to the side wall of the connecting rod 311. The spur gears 5 mesh with the teeth 6. Several sets of teeth 6 are arranged alternately on the inner top and bottom surfaces of the guide frame 307. When the suction pipe 204, the connecting rod 311, and the slider 312 move laterally, the teeth 6 and the spur gears 5 move relative to each other, causing the teeth 6 to drive the spur gears 5 to rotate, which in turn drives the suction pipe 204 to rotate. The suction pipe 204 not only moves laterally but also rotates around the axis of the connecting rod 311, thus forming a cleaning path similar to a fan sweeper. With a wider coverage area and reduced missed suction, the rotating suction port can continuously change the suction angle, which constantly changes the direction of the wind impact, which is conducive to disturbing the deposited dust, enhancing particle desorption, and improving the thoroughness of dust removal. The spur gear 5 reciprocates under the alternating drive of the top and bottom teeth 6, thereby driving the suction pipe 204 to reciprocate around the axis of the connecting rod 311. Unlike continuous rotation, it will not cause the cable and hose to become tangled, simplifying the cable layout. At the same time, the reciprocating rotation of the suction pipe 204 will periodically change the direction of the suction port, realizing the adsorption path at different angles, which can more effectively capture pollutants floating in the space or in the corner areas.

[0036] In this invention, during use, the dual-axis motor 301 drives the reciprocating screw 303 to rotate, and the slider 312 moves laterally back and forth along the inner top surface of the frame 1, causing the suction pipe 204 to move laterally back and forth. The suction pipe 204 is no longer fixed at a certain position or angle, covering a larger area of ​​pollution sources and improving collection efficiency. The half gear 310 rotates to drive the movable frame 305 to move longitudinally back and forth, further driving the limiting rod 308 to move longitudinally. The limiting rod 308 and the guide frame 307 drive the connecting rod 311 to move longitudinally back and forth, thereby causing the suction pipe 204 to swing longitudinally while moving laterally back and forth. The longitudinally swinging suction pipe 204 actively sweeps over areas that may form dead corners, which can more comprehensively cover pollution sources and expand the collection range.

[0037] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
