Description

Technical Field

[0001] The present invention relates to the technical field of metal coating equipment, in particular to an environmentally friendly coating production line purification system. Background Art

[0002] The spraying production line can spray the outer surface of metal parts, so that the outer surface of the metal parts is covered with a protective layer, thereby increasing the practical life of the metal parts. The working principle of the spraying production line is to use the principle of mutual adsorption of positive and negative electrostatic charges to evenly coat the resin powder on the surface of the workpiece, and then perform heat treatment to shape it. During spraying, various harmful exhaust gases and particulate matter will be generated. The spray purification system can adsorb the above-mentioned harmful gases.

[0003] In the prior art, for example, the utility model patent disclosed in publication number CN216322884U discloses an environmentally friendly spray coating production line with a purification structure, comprising a support column, a conveyor frame mounted on the top of the support column by bolts, and a drying box, a dust removal box, a spraying box, and a curing box being clamped to the outside of the conveyor frame, purification boxes being mounted on one side of the outer wall of the spraying box by bolts at equal distances, and the interior of the purification box being filled with purification liquid, air holes being opened on the top outer wall of the purification box, and an air pump being mounted on the top outer wall of the purification box by bolts, the input end of the air pump being threadedly connected to an air collecting pipe, and one end of the air collecting pipe extending into the interior of the spraying box, and the output end of the air pump extending into the interior of the purification box. The air pump of the utility model can extract the air from the interior of the spraying box and send it into the interior of the purification box through the air collecting pipe, so that harmful components in the air can be absorbed by the purification liquid inside the purification box to prevent them from being directly discharged into the air and causing harm to the environment and the health of production workers.

The upper end surface of the limiting slide 413 is slidably connected to the connecting workpiece 410 through a limiting clamping ring 48. The side end surface of one group of guide pulleys 412 is fixedly connected to the transmission gear 44. A motor holder 41 is provided on the side end surface of the filter box 415 near the transmission gear 44, and a servo motor 42 is fixedly connected to the inner end surface of the motor holder 41. The inner end surface of the servo motor 42 is fixedly connected to an incomplete gear 43. A diverter fan 417 is provided at the center of the lower end surface of the filter box 415, and an exhaust pipe 418 is symmetrically provided on the outer end surface of the diverter fan 417.

[0035] The inner end surface of the limiting clamp 23 is symmetrically provided with a supporting groove, and the supporting groove is coaxial with the positioning slide 22, the positioning slide 22, the guide sleeve 28 and the limiting clamp 48 are coaxial, and the limiting clamp 48, the material guide groove 47, the material guide groove 45 and the material guide slide 416 are coaxial. The supporting groove inside the limiting clamp 23 can cooperate with the positioning slide 22 for intermittent alignment, which is convenient for the subsequent connection of the workpiece 410 to be intermittently introduced into the interior of the limiting clamp 48 for loading.

[0036] The limiting clamping plate 23 is slidably clamped on the inner end surfaces of the two groups of positioning slides 22 through the limiting guide grooves 21 , and the first sealing clamping disc 31 and the second sealing clamping disc 33 are both sealedly connected to the connecting conduit 25 through the plug-in sealing grooves 32 .

[0037] The bottom of the connecting workpiece 410 is slidably connected to the limiting slide 413, and the side of the incomplete gear 43 is meshed with the transmission gear 44. The limiting slide 413 can provide sufficient limiting basis when the connecting workpiece 410 slides, so that the connecting workpiece 410 can rotate on its own, thereby improving the uniformity of coating. During transmission, the servo motor 42 can provide intermittent power to the transmission gear 44 through the incomplete gear 43, so that the two sets of guide pulleys 412 can intermittently drive the limiting clamping ring 48 to accurately load and unload the connecting workpiece 410.

[0038] The outer end face of the filter box 415 is sealed and fixedly connected to the connecting sealing plate 27 through two groups of sealing baffles 1. The connecting workpiece 410 is located between the two groups of spray guide tubes 35, and the connecting workpiece 410 does not contact the spray guide tubes 35. The filter box 415 forms a sealed space for coating through the sealing baffle 1 and the connecting sealing plate 27, which can effectively improve the sealing of the equipment during subsequent coating and prevent dust from escaping. The three groups of spray guide tubes 35 can perform all-round coating on the central connecting workpiece 410, thereby maximizing the uniformity of the coating.

[0039] The inner diameters of the positioning slide 22, the material guide slide 45, the material guide slide 47, the limiting clamp 48 and the material guide slide 416 are all equal to the outer diameter of the connected workpiece 410, which facilitates the subsequent precise loading positioning and unloading guiding of the connected workpiece 410, thereby improving the efficiency of the subsequent automated coating processing of the connected workpiece 410.

[0040] Working principle: Before use, the user can install the collection box to the bottom of the guide slide 416, and at the same time, the user can position the guide device of the external connection workpiece 410 to the upper part of the two sets of guide sleeves 28, so as to facilitate the subsequent continuous introduction of the connection workpiece 410 into the interior of the recycling and purification component 4. When the connection workpiece 410 is loaded, the servo motor 42 can drive the transmission gear 44 to intermittently engage and rotate through the front incomplete gear 43, so that the transmission gear 44 can drive the side guide pulley 412 to rotate. Since the two sets of guide pulleys 412 are engaged by the toothed belt 411, the toothed belt 411 is engaged with the transmission gear 44. The two sets of guide pulleys 412 can intermittently drive the toothed belt 411 to rotate. Each time the guide pulley 412 rotates, it can drive a set of limit clamps 48 to move to the bottom of the guide sleeve 28 and the positioning slide 22, which is convenient for the subsequent accurate loading and positioning of the connected workpiece 410. When spraying, the user can connect the air supply conduit 29 to the external supply pipe, so as to facilitate the subsequent supply of sufficient paint to the spray assembly 3 through the spray storage box 26 for spraying. When spraying, the staff can use the spray storage box 26 and the connecting conduit 25 to supply the first sealing chuck 31 and The second sealing chuck 33 provides sufficient paint inside, and the first sealing chuck 31 and the second sealing chuck 33 can guide the paint into the inside of the spray guide 35. The three groups of spray guides 35 can respectively perform a full range of spraying operations on the outside of the continuously displaced connecting workpiece 410 from the middle and both sides. When the above-mentioned connecting workpiece 410 is intermittently loaded, it can be continuously moved forward under the intermittent drive of the toothed belt 411. At this time, the multiple groups 37 can spray the connecting workpiece 410 from all angles, and when the connecting workpiece 410 is displaced, the side can fit with the limiting slide 413, thereby making the connecting workpiece 410 0 can rotate, which improves the uniformity of spraying. During spray purification, the three sets of exhaust motors 414 can absorb various waste gases from the spraying and introduce them into the filter box 415. The filter box 415 can purify the waste gas, and then introduce it into the diversion fan 417 through the filter box 415. The diversion fan 417 can introduce the waste gas into the external equipment through the exhaust pipe 418 for further purification. Since the bottom of the positioning slide 22 is intermittently sealed by the limiting card 23, and the bottom of the guide chute 45 has a collection box, the whole equipment is in a closed state, which can maximize the environmental protection of the equipment during spraying.

[0041] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
