Description

Technical Field

[0001] The invention relates to the technical field of paint spraying, in particular to a filter device for spraying protective oil. Background Art

[0002] The paint spraying process uses atomizing equipment such as air spray guns and electrostatic spray devices to evenly adhere paint to the surface of the workpiece, forming a durable coating through multiple layers of coating and curing. Its core process includes surface preparation, paint mixing, parameter-controlled spraying, and quality inspection. Filtering the paint before spraying is crucial because impurities such as particles and gels may be mixed into the paint during storage or transportation. If used directly without filtering, these impurities can clog the nozzle, cause particle defects on the coating surface, or affect the electrostatic adsorption effect, resulting in reduced coating uniformity and even rework. Therefore, filtration is a key pretreatment step to ensure spraying quality, extend equipment life, and improve the qualified rate of finished products. Existing filtering equipment, such as handheld spray guns, usually uses disposable filter funnels for filtering when adding paint. Therefore, it is difficult to reuse, resulting in difficulty in reducing costs. Frequent replacement of funnels also leads to reduced production efficiency. Summary of the Invention

[0019] In other aspects, the embodiment also provides a turnover mechanism 3 for driving the filtering hopper 204 to turn over from the filtering state to the impurity discharging state, as shown in Figure 2 and Figure 5 As shown, the turnover mechanism 3 comprises a lifting ring 302 and a turnover plate 306, the lifting ring 302 is arranged outside the oil cylinder 1, and the turnover plate 306 is arranged at the top end of the lifting ring 302.

[0020] In the embodiment, as shown in Figure 3 and Figure 5 The turnover mechanism 3 comprises a connecting cylinder 301 and a spring 303, the connecting cylinder 301 is fixedly sleeved on the outer wall of the oil cylinder 1, the lifting ring 302 is movably installed in the connecting cylinder 301, and the spring 303 is sleeved outside the oil cylinder 1 and located between the connecting cylinder 301 and the lifting ring 302; The spring 303 is placed through the connecting cylinder 301, when the lifting ring 302 descends, the spring 303 is compressed, and when the turnover plate 306 is pushed from the vertical state to the horizontal state, the lifting ring 302 is reset through the elastic force of the spring 303.

[0021] In the embodiment, as shown in Figure 4 The turnover mechanism 3 comprises a rack 304 and a gear 305, the rack 304 has two roots and is inserted and installed at the front and rear ends of the connecting frame 201, the gear 305 has two roots and is fixedly sleeved at the two ends of the rotating shaft 205, the two racks 304 are movably connected with the two gears 305 through meshing, and the bottom ends of the two racks 304 are fixedly connected with the end of the lifting ring 302 close to the connecting frame 201; When the rack 304 is lowered, the rotating shaft 205 is rotated by the gear 305, so that the filter hopper 204 is turned over from the top end of the oil cylinder 1 to the top end of the fixed cylinder 202; when the rack 304 is raised, the rotating shaft 205 is reversed by the gear 305, so that the filter hopper 204 is turned over from the top end of the fixed cylinder 202 back to the top end of the oil cylinder 1.

The turning plate 306 is rotated by pushing the magnetic push plate 307. The magnetic push plate 307 is magnetically connected with the fixed magnetic plate 308, so that the turning plate 306 can keep vertical after being rotated, and the filter hopper 204 can be kept at the top end of the fixed cylinder 202.

[0023] In other aspects, the embodiment also provides a protection mechanism 4 for closing and protecting the fixed cylinder 202 and the oil cylinder 1 to prevent leakage, as shown in the figure, Figure 6 The protection mechanism 4 includes a protection frame 403. The protection frame 403 is arranged at the top end of the oil cylinder 1.

[0024] In the embodiment, as shown in the figure, Figure 6 The protection mechanism 4 includes a protection cover 401 and a connecting rod 402. The protection cover 401 is fixedly installed at the top end of the fixed cylinder 202. The connecting rod 402 is fixedly installed at the top end of the side of the protection cover 401 close to the oil cylinder 1. The protection frame 403 is movably installed on the side of the protection cover 401 close to the oil cylinder 1. The top end of the fixed cylinder 202 is surrounded by the protection cover 401. After the filter hopper 204 is turned over to the top end of the fixed cylinder 202, the protection cover 401 is closed by the protection frame 403, so that the paint attached to the filter hopper 204 cannot splash out of the protection cover 401. The gear 305 is pressed by the protection frame 403, so that the gear 305 cannot be raised, and the filter hopper 204 can be kept at the top end of the fixed cylinder 202.

[0025] In the embodiment, as shown in the figure, Figure 6 The protection mechanism 4 includes two movable grooves 404 and a cylinder cover 405. The two movable grooves 404 are respectively arranged on the front and rear sides of the protection frame 403. The two ends of the connecting rod 402 are respectively inserted into the two movable grooves 404. The cylinder cover 405 is movably installed at the top end of the protection frame 403. The cylinder cover 405 is screwed at the top end of the oil cylinder 1. The protective frame 403 is connected to the connecting rod 402 through the movable groove 404, so that the protective frame 403 can rise on the side of the protective cover 401 close to the oil cylinder 1 under the limitation of the connecting rod 402 and the movable groove 404, and can rotate around the connecting rod 402, so that the rotated protective frame 403 can be placed on the protective cover 401, so that there is enough space at the top of the oil cylinder 1 to facilitate pouring spray protection oil into the filter bucket 204. The cylinder cover 405 can not only close the top of the oil cylinder 1, but also fix the protective frame 403 to the side of the protective cover 401.

[0026] Working principle: When the present invention is in use, the cylinder cover 405 is rotated to separate the cylinder cover 405 from the top of the oil cylinder 1, and then the protective frame 403 is pulled. Through the limit of the movable groove 404 and the connecting rod 402, the protective frame 403 is raised and can rotate on the top of the protective cover 401. After rotation, the protective frame 403 rests on the top of the protective cover 401. Then pour the paint protection oil into the filter bucket 204 and filter it through the filter bucket 204 so that the solid impurities in the paint protection oil are trapped in the filter bucket 204. After the filtration is completed, the magnetic dial plate 307 is toggled to drive the flip plate 306 to rotate. The flip plate 306 is squeezed with the top of the oil cylinder 1 to make the lifting ring 302 descend. At this time, the lifting ring 302 descends in the connecting cylinder 301 and compresses the spring 303. When the lifting ring 302 descends, the two racks 304 are driven to descend at the same time. When the racks 304 descend, the rotating shaft 205 is driven to rotate through the gear 305. When the rotating shaft 205 rotates, the filter bucket 204 is driven to rotate at the same time. When the flip plate 306 rotates 90 degrees, it rotates from a horizontal state to a vertical state. The magnetic plate 307 is fixedly connected to the fixed magnetic plate 308 through magnetism, and the rack 304 is driven to drop to the bottom through the lifting ring 302. At this time, the filter bucket 204 flips half a circle, so that the filter bucket 204 flips from the top of the oil drum 1 to the top of the fixed drum 202. At this time, the opening of the filter bucket 204 faces the collecting drum 203, so that the solid debris trapped in the filter bucket 204 falls into the collecting drum 203 and is collected. Then pull down the protective frame 403 so that the cylinder cover 405 returns to the top of the oil cylinder 1, and rotate the cylinder cover 405 so that the cylinder cover 405 is installed on the top of the oil cylinder 1. This not only fixes the protective frame 403 on the protective cover 401 and the oil cylinder 1, but also seals the protective cover 401 through the protective frame 403 to prevent the paint attached to the filter hopper 204 from splashing out from the protective cover 401 when the paint spraying equipment is in motion.
