Description

Technical Field

[0001] This utility model relates to the field of metal product processing technology, and more specifically, to a metal product surface spraying equipment. Background Technology

[0002] Metals (especially steel) are prone to corrosion in natural environments due to oxidation, moisture, acid and alkali erosion, etc., which leads to a decrease in structural strength and a shortened service life. Usually, spraying equipment is used to spray the surface of metal products. The resulting coating can isolate the metal substrate from contact with air, moisture and corrosive media. For example, painting can significantly delay corrosion and extend the service life of car bodies and outdoor metal guardrails.

[0003] However, existing spraying equipment requires workers to hold the spray gun and spray, and the spraying area on metal products is open, causing the paint to diffuse into the air, which poses a significant health hazard to workers. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a metal product surface spraying equipment to solve the problem that when using the existing spraying equipment, the operator needs to hold the spray gun to perform the spraying operation, and the metal product spraying area is in an open state, and the paint will diffuse into the air, which will cause great harm to the health of the operator.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a metal product surface spraying equipment, including a conveyor frame, a conveyor rail fixedly installed on the top of the conveyor frame, a plurality of hanging wheel frames evenly rolled on the conveyor rail, a conveying component arranged between the plurality of hanging wheel frames, a hanging rod arranged on the hanging wheel frame, a sealing cover installed on the conveyor frame below the conveyor rail, a rod groove opened on the top of the sealing cover, symmetrical sealing curtains arranged on the left and right sides of the sealing cover, a spraying component arranged on the front side of the sealing cover, a negative pressure component arranged at the bottom of the sealing cover, and an adjustment component arranged on the conveyor rail.

[0006] Preferably, the width of the rod groove is greater than the width of the hanging rod.

[0007] Preferably, the spraying assembly includes a spraying pump, which is installed on the top of the sealing cover. The output end of the spraying pump is connected to a material delivery pipe. Several nozzles are evenly distributed vertically inside the sealing cover, and each nozzle is connected to the material delivery pipe.

[0008] Preferably, the front side of the sealing cover is uniformly rotatably provided with incomplete gears corresponding one-to-one with the nozzles in the vertical direction. The nozzles are fixedly connected to the incomplete gears. A slide rail is fixedly installed on the outer side of the sealing cover. A slide plate is vertically slidably installed on the slide rail. A rack is provided on the side of the slide plate facing the incomplete gear. The incomplete gear meshes with the rack. A telescopic cylinder is fixedly installed on the slide rail. The telescopic end of the telescopic cylinder is fixedly connected to the slide plate.

[0009] Preferably, the negative pressure assembly includes a negative pressure pump, the input end of which is connected to the bottom of the sealing cover, and a perforated plate is installed on the inner side of the sealing cover, the perforated plate being located below the sealing curtain.

[0010] Preferably, the positioning assembly includes a motor, the output end of which is connected to a bevel gear one, a sleeve is rotatably connected to the bottom of the conveyor rail, a bevel gear two is fitted on the sleeve, the bevel gear one and the bevel gear two mesh, an insert is vertically slidably inserted into the sleeve, a magnetic attractor is fixedly connected to the bottom end of the insert, a spring is fitted on the outside of the insert, the two ends of the spring are fixedly connected to the sleeve and the magnetic attractor respectively, and a magnetic block is fixedly installed on the top of the hanging rod.

[0011] Preferably, the spring is an electromagnet.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention uses a hanging rod to move along the rod groove to lift the sealing curtain and enter the sealing cover, so that the metal product is sealed and wrapped by the sealing cover and sealing curtain. Then, the metal product is rotated and sprayed evenly by the spraying component and the adjustment component. At the same time, the negative pressure component is used to filter the paint drifting in the sealing cover to prevent the paint from spreading in the processing environment and to ensure the health of the workers.

[0014] This invention uses a telescopic cylinder to reciprocate, which drives the rack on the slide plate to engage the incomplete gear, thereby causing the spray head to swing up and down. Multiple spray heads spray paint onto the surface of the part at different angles, allowing the paint to be sprayed onto the surface of the part at different angles, thus ensuring that the dead corners of the part are fully and evenly coated.

[0015] This invention utilizes a negative pressure pump to extract the paint that has been sprayed and dispersed inside the sealed cover through the mesh of a perforated plate, thereby further reducing the paint content in the air and preventing the paint from spreading outward from inside the sealed cover.

[0022] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0023] As attached Figure 1 To be continued Figure 4 This utility model provides a metal product surface spraying device, including a conveyor frame 1, a conveyor rail 2 fixedly installed on the top of the conveyor frame 1, a plurality of hanging wheel frames 3 evenly rolled on the conveyor rail 2, a conveying component 4 arranged between the plurality of hanging wheel frames 3, a hanging rod 5 arranged on the hanging wheel frame 3, a sealing cover 6 located below the conveyor rail 2 installed on the conveyor frame 1, a rod groove 7 opened on the top of the sealing cover 6, symmetrical sealing curtains 8 arranged on the left and right sides of the sealing cover 6, a spraying component 9 arranged on the front side of the sealing cover 6, a negative pressure component 10 arranged at the bottom of the sealing cover 6, and an adjustment component 11 arranged on the conveyor rail 2.

[0024] Among them, the conveyor 4 is existing technology, which can drive the hanging wheel frame 3 to move along the conveyor rail 2 and convey the metal workpiece to the sealing cover 6.

[0025] Specifically, during the spraying process, metal products are hung on the hanging rod 5, and the conveyor 4 transports the metal products one by one to the sealing cover 6. At this time, the hanging rod 5 moves along the rod groove 7 to lift the sealing curtain 8 and enter the sealing cover 6, so that the metal products are sealed and wrapped by the sealing cover 6 and the sealing curtain 8. Then, the spraying component 9 and the adjusting component 11 make the metal products rotate and spray evenly. At the same time, the negative pressure component 10 is used to filter the paint drifting in the sealing cover 6 to prevent the paint from spreading in the processing environment and to ensure the health of the workers.

[0026] Preferably, the width of the rod groove 7 is greater than the width of the hanging rod 5, so as to ensure that the hanging rod 5 can accurately enter the rod groove 7.

[0027] Preferably, the spraying assembly 9 includes a spraying pump 91, which is installed on the top of the sealing cover 6. The output end of the spraying pump 91 is connected to a material delivery pipe 92. Several nozzles 93 are evenly distributed in the vertical direction inside the sealing cover 6, and all of the nozzles 93 are connected to the material delivery pipe 92.

[0028] The input end of the spray pump 91 is connected to the paint supply system. By starting the spray pump 91, the paint can be transported through the feed pipe 92 and then sprayed onto the surface of the metal workpiece from the nozzle 93.

[0029] Furthermore, the front side of the sealing cover 6 is uniformly rotatably equipped with incomplete gears 94 corresponding to the nozzles 93. The nozzles 93 are fixedly connected to the incomplete gears 94. A slide rail 95 is fixedly installed on the outer side of the sealing cover 6. A slide plate 96 is vertically slidably installed on the slide rail 95. A rack 97 is provided on the side of the slide plate 96 facing the incomplete gears 94. The incomplete gears 94 and the rack 97 mesh with each other. A telescopic cylinder 98 is fixedly installed on the slide rail 95. The telescopic end of the telescopic cylinder 98 is fixedly connected to the slide plate 96.

[0030] Specifically, since some parts have uneven surfaces and dead corners, resulting in uneven coating, during the coating process, the telescopic cylinder 98 reciprocates, which drives the rack 97 on the slide plate 96 to engage the incomplete gear 94, thereby driving the nozzle 93 to swing up and down. Multiple nozzles 93 spray paint onto the surface of the parts at different angles, so that the paint is sprayed onto the surface of the parts at different angles, thus ensuring that the dead corners of the parts are fully and evenly coated.

[0031] Furthermore, the negative pressure assembly 10 includes a negative pressure pump 101, the input end of which is connected to the bottom of the sealing cover 6, and a mesh plate 102 is installed on the inner side of the sealing cover 6, which is located below the sealing curtain 8.

[0032] The output end of the negative pressure pump 101 can be connected to an external paint collection and treatment system. By starting the negative pressure pump 101, the paint that has been sprayed and dispersed inside the sealing cover 6 can be sucked out and treated using the mesh of the mesh plate 102, thereby further reducing the paint content in the air and preventing the paint from spreading outward from inside the sealing cover 6.

[0033] Preferably, the positioning assembly 11 includes a motor 111, the output end of which is connected to a bevel gear 112, a sleeve 113 is rotatably connected to the bottom of the conveyor rail 2, a bevel gear 114 is fitted on the sleeve 113, the bevel gear 112 meshes with the bevel gear 114, a vertically sliding insert 115 is inserted into the sleeve 113, a magnetic attractor 117 is fixedly connected to the bottom end of the insert 115, a spring 116 is fitted on the outside of the insert 115, the two ends of the spring 116 are fixedly connected to the sleeve 113 and the magnetic attractor 117 respectively, and a magnetic block 118 is fixedly installed on the top of the hanging rod 5.

[0034] Preferably, the spring 116 is an electromagnet.

[0035] Specifically, when the magnetic block 118 on the hanging rod 5 moves to directly below the spring 116, the conveying of the metal parts by the conveying component 4 is paused. At the same time, the magnetic suction component 117 magnetically attracts the magnetic block 118. Then, the motor 111 drives the bevel gear 112 to mesh with the bevel gear 114, causing the sleeve 113 and the insert 115 to drive the magnetic suction component 117 to rotate. Then, the magnetic force between the magnetic suction component 117 and the magnetic block 118 is used to make the hanging rod 5 drive the metal parts to rotate, so that the spraying component 9 can spray the surface of the metal parts evenly. After the spraying is completed, the hanging rod 5 continues to convey forward, the magnetic suction component 117 separates from the magnetic block 118, and the spring 116 contracts to drive the magnetic suction component 117 to rise.
