[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Example 1

[0032] One type of existing coating machine filtration device uses multiple filter screens for filtration. However, this filtration method requires frequent replacement of the filter screens. Not only will the filtration performance decrease over time, but frequent replacement of the filter screens will also increase production costs. Figure 1-Figure 7 This embodiment provides a dust removal and filtering device for a coating machine, which can solve the problem of filter performance degradation over time. The device includes a support plate 1 providing a support base, a coating machine 2 mounted on top of the support plate 1 via a bracket, a dust removal and filtering mechanism 3 provided on the support plate 1 for filtering exhaust gas from the coating machine 2, and a transmission mechanism 4 provided on the support plate 1 below the coating machine 2 for providing power to the coating machine 2 and the dust removal and filtering mechanism 3. The transmission mechanism 4 provides power to the dust removal and filtering mechanism 3, thereby enabling the dust removal and filtering mechanism 3 to filter the exhaust gas from the coating machine 2.

[0033] In order to pump air to the air pump assembly 303 through the transmission mechanism 4, the dust removal and filtration mechanism 3 is used to filter and remove dust, which can fully utilize the motorized equipment while saving the investment in the water pump. The dust removal and filtering mechanism 3 includes a docking pipe 301 rotatably connected to the air outlet end of the coating machine 2, and the air outlet end of the docking pipe 301 is fixedly connected to a filter bin 302, and a water tank 304 is installed on the top of the filter bin 302. A pumping assembly 303 for pumping air into the water tank 304 is provided on one side of the filter bin 302. The pumping assembly 303 includes an air pump tank 3031 arranged at the top of the support plate 1, and an air pump plug 3032 is slidably connected to the inner side of the air pump tank 3031. One end of the air pump plug 3032 is fixedly connected to a push-pull rod 3033 extending to the outside of the air pump tank 3031. A one-way valve 3034 is installed on one side of the top and the air outlet end of the air pump tank 3031. The air outlet end of the one-way valve 3034 installed at the air outlet end of the air pump tank 3031 is connected to an air pipe 3035, and the air outlet end of the air pipe 3035 is connected to the top of the water tank 304.

[0034] In order to remove dust from the exhausted air by spraying water mist, a water filling rack 305 connected to the water outlet of the water tank 304 is installed at the top of the inner side of the filter chamber 302. A plurality of atomizing nozzles 306 are installed at the bottom of the water filling rack 305. To prevent water mist from entering the interior of the coating machine 2, a backflow prevention window 307 is fixedly connected to the air outlet end of the connecting pipe 301 inside the filter chamber 302. Two baffles 308 are fixedly connected to the inner side of the backflow prevention window 307.

[0035] The push-pull rod 3033 is driven by the transmission mechanism 4 to move back and forth inside the pump tank 3031, and the pump gas plug 3032 fixedly connected at one end of the push-pull rod 3033 also moves back and forth inside the pump tank 3031. When the pump gas plug 3032 moves toward the air pipe 3035, the one-way valve 3034 on the top side of the pump gas tank 3031 will close, and the other one-way valve 3034 will open, so that the air inside the pump gas tank 3031 will be discharged to the air pipe 3035 through the one-way valve 3034. When the pump gas plug 3032 moves in the direction away from the air pipe 3035, the one-way valve 3034 connected to the air pipe 3035 will close, and the other one-way valve 3034 will open. A one-way valve 3034 will drive the pump tank 3031 to ventilate the outside world, and this reciprocating cycle can realize the function of pumping air. Air is continuously pumped into the water tank 701 through the air pipe 3035. The water tank 701 will drain into the water filling rack 305 connected to it due to the increase in internal air pressure, and the water inside the water filling rack 305 will be sprayed out through several atomizing nozzles 306 connected to its bottom end, thereby removing dust from the air entering the filter bin 302. The anti-backflow window 307 installed at the air inlet end of the filter bin 302 is connected to the air outlet end of the coating machine. The baffle 308 inside the anti-backflow window 307 can prevent the water inside the filter bin 302 from entering the coating machine.

The driving gear 402 is fixedly connected to a rotating shaft 403 at one end away from the conveying motor 401, and an eccentric disk 404 is fixedly connected to the end of the rotating shaft 403. The eccentric disk 404 is eccentrically connected to a connecting rod 405 at one end away from the rotating shaft 403, and the end of the connecting rod 405 is rotatably connected to the end of the push-pull rod 3033.

[0038] The transmission motor 401 drives the driving gear 402 at its transmission end to rotate, and the driving gear 402 drives the eccentric disk 404 fixedly connected thereto to rotate, and the eccentric disk 404 drives the connecting rod 405 rotatably connected at the other end thereof to rotate, and the connecting rod 405 drives the push-pull rod 3033 rotatably connected thereto to rotate, during which the driving gear 402 also drives the coating machine 2 used in conjunction therewith to rotate.

[0039] In order to be able to discharge the material processed inside the coating machine 2 after opening the discharge sealing plate 6. One end of the outer side of the coating machine 2 is movably connected with the discharge sealing plate 6, and a discharge inclined plate 7 is provided on one side of the discharge sealing plate 6 below the coating machine 2.

[0040] In order to make it more convenient to add raw materials in the early stage of processing, a feeding and air-drying mechanism 5 for adding materials into the coating machine 2 is provided on the support plate 1 at the feeding end of the coating machine 2. The feeding and air-drying mechanism 5 includes a movable slide 501 installed at the top of the support plate 1 at the feeding end of the coating machine 2, a fixed rod 502 is slidably connected to the inner side of the movable slide 501, an extension frame 503 is fixedly connected to one side of the top of the fixed rod 502, a closing plate 504 is fixedly connected to the outer side of the extension frame 503, and a plurality of assembly pipes 505 are connected to the inner side of the extension frame 503. The feeding ends of the plurality of assembly pipes 505 are respectively connected to the external feeding and water supply equipment and the output end of the hot air blower.
