Description

Technical Field

[0001] This application relates to the technical field of spraying equipment, and more particularly to a spraying equipment for the body of a three-wheeled electric vehicle. Background Technology

[0002] As an important tool for short-distance transportation and daily commuting, the body of three-wheeled electric vehicles is mostly made of metal or composite materials. In the production process of three-wheeled electric vehicles, painting the body is one of the key processes. By forming a uniform and dense coating, it can effectively isolate external corrosive media, protect the body substrate, and give the vehicle a specific appearance color.

[0003] In related technologies, the painting operation for the body of a three-wheeled electric vehicle usually involves preloading the paint to be painted into a storage tank, connecting the storage tank to the spray gun through a connecting pipe, turning on the air compressor to provide power, and controlling the switch on the spray gun so that the paint in the storage tank is atomized by the spray gun nozzle under air pressure and then evenly sprayed onto the surface of the three-wheeled electric vehicle body.

[0004] However, relevant staff discovered that during the painting process, some paint atomization particles did not adhere to the vehicle body surface and diffused directly into the surrounding air, forming paint dust pollution. This not only wastes paint raw materials but also pollutes the workshop production environment. The paint particles diffused into the air can also be easily inhaled by operators or adhere to the skin surface. Long-term exposure can damage the respiratory system, skin and mucous membranes of operators. Summary of the Invention

[0024] Embodiments of this application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. Rather, embodiments of this application include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0025] The following describes a three-wheeled electric vehicle body painting device according to an embodiment of this application, with reference to the accompanying drawings.

[0026] like Figures 1-8 As shown, the three-wheeled electric vehicle body painting equipment of this application embodiment may include a storage tank 100, a painting device 200, a fixing device 300 and a recycling device 400.

[0027] The spraying device 200 may include a spraying assembly 210 and a nozzle assembly 220. The spraying assembly 210 is located directly above the storage tank 100, and the nozzle assembly 220 is fixedly connected to the left end of the spraying assembly 210.

[0028] The fixing device 300 may include a fixing component 310 and a supporting component 320. The fixing component 310 is movably connected to the spraying component 210. One end of the supporting component 320 is movably connected to the fixing component 310, and the other end of the supporting component 320 is connected to the spraying component 210.

[0029] The recycling device 400 may include a protective component 430, a suction component 420, and a storage component 410.

[0030] The protective component 430 is threadedly connected to the nozzle component 220, the suction component 420 is installed on the top of the protective component 430, the storage component 410 is located on the right side of the spraying component 210, and the end of the suction component 420 away from the protective component 430 is connected to the storage component 410.

[0031] Furthermore, a connecting rod 101 is fixed to the top of the storage tank 100. One end of the connecting rod 101 is fixedly connected to the top of the storage tank 100, and the other end of the connecting rod 101 is detachably connected to the bottom of the spray gun 211.

[0032] Specifically, when it is necessary to spray paint on the body of the three-wheeled electric vehicle, the relevant personnel hold the spraying component 210 and bring the protective component 430 close to the area of ​​the three-wheeled electric vehicle to be sprayed. The spraying operation is started by triggering the control component on the spraying component 210. At this time, the air pressure provided by the external air compressor pushes the paint in the storage tank 100 through the internal channel of the spraying component 210 to the nozzle component 220 at the left end. After the paint is atomized by the nozzle component 220, it is evenly sprayed on the surface of the three-wheeled electric vehicle body.

[0033] Simultaneously, the suction component 420 starts working, creating negative pressure in the suction channel. The scattered paint that is not attached to the car body after being atomized by the nozzle component 220 is constrained in its internal space by the protective component 430. Then, under the negative pressure of the suction component 420, it enters the suction component 420 through the collection structure at the top of the protective component 430, and is then transported by the suction component 420 to the storage component 410 located to the right of the spraying component 210, completing the recovery and storage of the scattered paint.

[0034] After the spraying operation is completed, the fixing component 310 is stored back into the storage structure of the spraying component 210, the threaded connection between the protective component 430 and the nozzle component 220 is disassembled, the protective component 430 and the suction component 420 are removed, and finally the storage tank 100 is disassembled through the connecting rod 101 to clean or replace the empty tank.

[0035] In one embodiment of this application, such as Figure 2 , Figure 3 and Figure 4 As shown, the spraying assembly 210 may include a spray gun 211, a control switch 212, a handle 213, and a connector 214.

[0036] The spray gun 211 is positioned above the storage tank 100, the control switch 212 is embedded in the side wall of the spray gun 211, the handle 213 is vertically fixed to the bottom of the spray gun 211, and the connector 214 is integrally formed at the bottom of the handle 213.

[0037] Furthermore, a storage groove 215 is provided at the top of the spray gun 211, and a slot 216 is provided on the inner side wall of the storage groove 215. The fixing component 310 is movably placed in the storage groove 215, and the end of the support component 320 away from the fixing component 310 is inserted into the slot 216. A connecting pipe 217 is also connected to the side wall of the spray gun 211. One end of the connecting pipe 217 is connected to the inside of the spray gun 211, and the other end of the connecting pipe 217 is connected to the inside of the storage tank 100.

[0038] Furthermore, the nozzle assembly 220 may include a connecting block 221, a fixing block 222, and a nozzle body 223.

[0039] The connecting block 221 is fixedly installed at the left end of the spray gun 211, the fixing block 222 is fixed at the left end of the connecting block 221, the nozzle body 223 is embedded in the left end of the connecting block 221, and one end of the nozzle body 223 is connected to the interior of the spray gun 211.

[0040] Specifically, the connecting rod 101 fixed at the top of the storage tank 100 is screwed into the pre-set internal threaded hole at the bottom of the spray gun 211, so that the spray gun 211 and the storage tank 100 can be detachably fixed. The control switch 212 is a push-button mechanical switch, which is embedded in the middle of the side wall of the spray gun 211. The bottom of the switch is linked to the paint channel valve inside the spray gun 211 through an internal connecting rod. When the control switch 212 is pressed, the valve can be pushed to open, so that the paint flows along the internal channel of the spray gun 211. When the switch is released, the valve closes, cutting off the paint delivery, so as to realize convenient control of spraying start and stop. The connector 214 is integrally formed with the bottom of the handle 213. Its internal channel is connected to the internal air passage of the handle 213 and the spray gun 211. The connector 214 is used to connect the hose of the external air compressor. Compressed air enters the interior of the spray gun 211 through the connector 214 to provide air pressure for paint atomization and spraying.

[0041] A storage groove 215 is provided at the top of the spray gun 211 along the length of the rod to store the support plate 311 when it is not in use. At the same time, slots 216 are symmetrically provided on the inner side wall of the storage groove 215. The width of the slot 216 is adapted to the thickness of the support plate 321 in the support assembly 320, so that one end of the support plate 321 can be inserted to support and fix the support plate 311.

[0042] The nozzle body 223 has an atomizing chamber inside, and a flow divider and a nozzle are installed inside the chamber. After the paint enters the atomizing chamber, it is dispersed by the flow divider under the action of compressed air, and then atomized into fine particles through the nozzle. The particles are sprayed out from the nozzle on the left end of the nozzle body 223 and evenly cover the surface of the three-wheeled electric vehicle.

[0043] In the painting operation of the three-wheeled electric vehicle body, the relevant personnel first inject the paint to be painted into the storage tank 100. Then, the relevant personnel hold the handle 213, aim the nozzle body 223 at the area of ​​the vehicle body to be painted, and press the control switch 212 to open the paint channel. At this time, the compressed air provided by the air compressor enters the spray gun 211 through the connector 214, pushing the paint in the storage tank 100 into the internal channel of the spray gun 211 along the connecting pipe 217, and then into the connecting block 221 and flow to the nozzle body 223. The paint is mixed with the compressed air in the atomization chamber of the nozzle body 223 and then atomized into fine particles, which are sprayed out from the nozzle and evenly adhered to the surface of the vehicle body.

[0044] In one embodiment of this application, such as Figure 5 and Figure 6 As shown, the fixing component 310 may include a support plate 311, a retaining ring 312, a first bolt 313, and a hinge block 314.

[0045] The bottom end of the support plate 311 is movably connected to the wall of the storage groove 215, and the support plate 311 can be completely stored in the storage groove 215. One end of the retaining ring 312 is hinged to the top end of the support plate 311. The first bolt 313 passes through the other end of the retaining ring 312 and is threadedly connected to the support plate 311. The hinge block 314 is fixed on the bottom side wall of the support plate 311, and the support assembly 320 is hinged to the hinge block 314.

[0046] Furthermore, the support assembly 320 may include a support plate 321, a fixing plate 322, and a second bolt 323.

[0047] One end of the support plate 321 is hinged to the hinge block 314, and the other end of the support plate 321 is inserted into the slot 216. The fixing plate 322 is fixed to the front and rear ends of the support plate 321 respectively. The second bolt 323 passes through the fixing plate 322 and is threaded to the side wall of the spray gun 211.

[0048] Specifically, the length and width of the support plate 311 are adapted to the depth and width of the storage slot 215, respectively, to ensure that it can be fully embedded in the storage slot 215 when idle, without protruding from the top surface of the spray gun 211, so as to avoid occupying extra space or interfering with operation. When in use, it can be rotated upward around the hinge to a state perpendicular to the storage slot 215, forming support for the suction tube 422.

[0049] Before painting the body of the three-wheeled electric vehicle, the relevant personnel first rotate the support plate 311 in the storage slot 215 upwards until the support plate 311 is in a vertical state. Then, the support plate 321 is rotated away from the support plate 311 around the pin axis of the hinge block 314 until the support plate 321 is in a horizontal state. The free end of the support plate 321 is inserted into the slot 216 on the inner side wall of the storage slot 215. Next, the second bolt 323 is passed through the fixing plate 322 and screwed into the threaded hole on the side wall of the spray gun 211. The second bolt 323 is tightened to complete the fixing of the support plate 321. At this time, the support plate... The plate 311 is stably supported and can bear the weight of the suction tube 422. Then, the suction tube 422 of the recycling device 400 is placed in the arc-shaped groove at the top of the support plate 311, ensuring that one end of the suction tube 422 is connected to the dust hood 433 of the protective component 430. Then, the retaining ring 312 is rotated to fasten it to the outside of the suction tube 422. The first bolt 313 is passed through the retaining ring 312 and screwed into the threaded hole of the support plate 311. The first bolt 313 is tightened to clamp and fix the suction tube 422, preventing the suction tube 422 from shifting position due to equipment movement or negative pressure of the air pump during the spraying process.

[0050] After the spraying operation is completed, the operator first unscrews the first bolt 313, opens the retaining ring 312, removes the suction tube 422, then unscrews the second bolt 323, rotates the support plate 321 around the pin axis in the direction of the support plate 311, so that the support plate 321 fits against the side wall of the support plate 311, and finally rotates the support plate 311 around the bottom hinge into the storage groove 215 until the support plate 311 is completely embedded in the storage groove 215.

[0051] In one embodiment of this application, such as Figure 7 and Figure 8 As shown, the protective component 430 may include a protective cover 431, a threaded sleeve 432, and a dust hood 433.

[0052] Among them, the threaded sleeve 432 is sleeved on the outside of the connecting block 221 and threadedly connected to the connecting block 221, the protective cover 431 is fixed on the left end of the threaded sleeve 432 and covers the outside of the nozzle body 223, the dust suction cover 433 is fixed on the top of the inner side wall of the protective cover 431, and the suction component 420 is connected to the dust suction cover 433.

[0053] Furthermore, the suction assembly 420 may include an air pump 421 and a suction tube 422. One end of the suction tube 422 is fixedly connected to and communicates with the top of the dust hood 433, and the other end of the suction tube 422 is communicated with the storage assembly 410. The tube body of the suction tube 422 is clamped between the support plate 311 and the retaining ring 312. The air pump 421 is disposed on the tube body of the suction tube 422 and communicates with the suction tube 422.

[0054] Furthermore, the storage component 410 may include a recycling bin 411 and an exhaust pipe 412. The recycling bin 411 is located directly below the air pump 421. The end of the suction pipe 422 away from the dust hood 433 is connected to the interior of the recycling bin 411. The exhaust pipe 412 is fixed to the top of the recycling bin 411 and is connected to the interior of the recycling bin 411.

[0055] Specifically, during assembly, the threaded sleeve 432 is inserted from the left end of the connecting block 221, and the threaded sleeve 432 is rotated clockwise until the right end of the threaded sleeve 432 is in contact with the stepped surface of the connecting block 221, thereby achieving the detachable fixation of the protective component 430 and the nozzle assembly 220. The protective cover 431 is a horn-shaped metal cover, and the edge of the small end is fixedly connected to the left edge of the threaded sleeve 432 by welding. After assembly, the protective cover 431 completely covers the outside of the nozzle body 223. The dust suction cover 433 is a funnel-shaped plastic or metal cover, and the edge of the large end is fixed to the inner wall of the protective cover 431 by welding or bonding. The outer wall of the small end of the dust suction cover 433 is provided with external threads for connecting to the suction tube 422 of the suction component 420. Its internal channel is connected to the inside of the protective cover 431, which can collect the paint particles floating inside the protective cover 431.

[0056] During the painting operation of the three-wheeled electric vehicle, the relevant personnel hold the handle 213, bring the large end of the protective cover 431 close to the area of ​​the vehicle to be painted, and press the control switch 212 to start the painting. Some of the paint atomized particles sprayed from the nozzle body 223 adhere to the vehicle body to form a coating, while the unadhered drifting paint is constrained in the internal space by the protective cover 431. At the same time, the air pump 421 is started, creating a negative pressure in the suction pipe 422. The drifting paint is sucked into the dust collection hood 433 and transported to the recycling box 411 through the suction pipe 422, where it is adsorbed and collected by the adsorption material. The clean gas after the paint separation in the recycling box 411 is discharged to the external environment through the exhaust pipe 412.

[0057] In summary, the three-wheeled electric vehicle body painting equipment of this application embodiment can recycle and reuse scattered paint, thereby effectively reducing paint waste and workshop environmental pollution, and preventing operators from inhaling or coming into contact with paint particles in the air to protect their health.
