Description

Technical Field

[0001] This application relates to the field of arc spraying technology, and more specifically, to an anti-splash dust collection cover for an arc spraying robot. Background Technology

[0002] In modern manufacturing, arc spraying technology, with its advantages of high efficiency and excellent coating quality, is widely used in fields such as metal surface corrosion protection and mechanical parts repair. Arc spraying robots, through automated operation, further improve spraying efficiency and precision, playing an important role in industries such as automotive manufacturing and aerospace.

[0003] However, the arc spraying process generates a large amount of dust, which contains harmful substances such as metal particles. If inhaled by operators, it will seriously endanger their health. At the same time, the dust will also pollute the workshop environment and increase equipment maintenance costs.

[0004] To address the aforementioned issues, this application provides a splash-proof dust collection cover for an arc spraying robot. Utility Model Content

[0005] One objective of this application is to provide a splash-proof dust collection hood for an arc spraying robot, comprising a dust collection bin and a spray gun. A dust suction hood is fixedly connected to the outside of the spray gun. An annular channel is formed inside the dust suction hood. A dust suction port communicating with the annular channel is formed on the inner bottom wall of the dust suction hood. An annular tube is provided at the top of the dust suction hood and outside the spray gun. The inner and outer bottom walls of the annular tube are fixedly connected to the dust suction hood. Multiple dust suction holes are formed on the inner wall of the dust suction hood. A connecting pipe is fixedly connected to the outside of the dust collection bin. A flexible hose is fixedly connected between the connecting pipe and the annular tube. A high-efficiency filter, a medium-efficiency filter, and a pre-filter are fixedly connected to the inner wall of the dust collection bin from top to bottom. A fan is fixedly connected to the inner top wall of the dust collection bin. A cover plate is provided on the outside of the dust collection bin.

[0006] Furthermore, all of the aforementioned suction holes are connected to the annular channel, and the aforementioned suction holes are arranged in a annular array.

[0007] Furthermore, a rotating rod is rotatably connected to the inner top wall of the dust collection bin. The bottom end of the rotating rod passes through the middle of the high-efficiency filter, the medium-efficiency filter, and the pre-filter from top to bottom, and extends to the bottom of the pre-filter. Dust collection ports are provided on both the medium-efficiency filter and the pre-filter. A double-sided brush and a brush body are fixedly connected to the outside of the rotating rod. A motor for driving the rotating rod to rotate is fixedly connected to the top of the dust collection bin.

[0008] Furthermore, two double-sided brushes are provided, which are respectively located on the upper and lower sides of the medium-efficiency filter screen, and the opposite sides of the two double-sided brushes respectively contact the opposite sides of the high-efficiency filter screen and the pre-filter screen. The brush body is located at the bottom of the pre-filter screen.

[0009] Furthermore, both the primary and secondary filters are fixedly connected to a baffle at their top, and the surface of the baffle is at the same level as the inner wall of the dust inlet.

[0010] Furthermore, the height of the baffle at the top of the primary filter is lower than the height of the baffle at the top of the secondary filter. Both the secondary and primary filters are provided with sealing plates at their bottoms, corresponding to the dust inlet. The two sealing plates are fixedly connected to the double-sided brush and the brush body, respectively.

[0011] Furthermore, the double-sided brush includes a handle one, with bristles one on both the upper and lower ends of the handle one, and the brush body includes a handle two, with bristles two on the inner side of the handle two.

[0012] The beneficial effects of this application are:

[0013] 1. The fan operates by using connecting pipes, hoses, ring pipes, ring channels, suction ports, and suction holes to draw in dust, collecting it to the lower part of the dust collection bin. This prevents dust from scattering on the work area and polluting the workshop environment, protecting the health of operators. Multiple suction ports and suction inlets increase the suction area. The combination of primary, secondary, and high-efficiency filters achieves multi-stage filtration. The primary filter intercepts larger dust particles, the secondary filter further filters finer particles, and the high-efficiency filter filters micron-sized particles, resulting in deep dust purification. The purified air is then discharged from the front of the fan.

[0014] 2. The control motor drives the rotating rod to rotate, which in turn drives the double-sided brush, brush body, and sealing plate to rotate. The rotation of the double-sided brush and brush body cleans the bottom of the high-efficiency, medium-efficiency, and pre-filters. Meanwhile, the bristles on the bottom of the double-sided brush sweep away the dust that falls from the brush, preventing dust from falling onto the top of the pre-filter and medium-efficiency filter. When the double-sided brush rotates to the dust collection port, the dust swept away by the rotation falls into the lower part of the dust collection bin, thus collecting the cleaned dust. Opening the cover facilitates cleaning the dust inside the dust collection bin, thereby achieving automatic cleaning of multiple filters without manual cleaning. Attached Figure Description

[0026] Example:

[0027] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 This application discloses an anti-splash dust collection hood for an arc spraying robot, including a dust collection bin 1 and a spray gun 7. A dust collection hood 9 is fixedly connected to the outside of the spray gun 7. An annular channel 13 is formed inside the dust collection hood 9. A dust suction port 14 communicating with the annular channel 13 is formed on the inner bottom wall of the dust collection hood 9. An annular tube 8 is provided at the top of the dust collection hood 9 and outside the spray gun 7. The inner and outer bottom walls of the annular tube 8 are fixedly connected to the dust collection hood 9. A plurality of dust suction holes 15 are formed on the inner wall of the dust collection hood 9. A connecting pipe 5 is fixedly connected to the outside of the dust collection bin 1. A flexible hose 6 is fixedly connected between the connecting pipe 5 and the annular pipe 8. From top to bottom, a high-efficiency filter 16, a medium-efficiency filter 17, and a primary filter 12 are fixedly connected to the inner wall of the dust collection bin 1. The pore size of the high-efficiency filter 16 is smaller than that of the medium-efficiency filter 17, and the pore size of the medium-efficiency filter 17 is smaller than that of the primary filter 12. A fan 2 is fixedly connected to the inner top wall of the dust collection bin 1, with the front end of the fan 2 penetrating through the dust collection bin 1. The sidewall extends to the outside of the dust collection bin 1. The control fan 2 operates through the connection pipe 5, hose 6, annular pipe 8, annular channel 13, suction port 14, and suction hole 15 to suck up dust. The multiple suction holes 15, in conjunction with the suction port 14, increase the suction area. The primary filter 12, medium-efficiency filter 17, and high-efficiency filter 16 work together to achieve multi-stage filtration of dust. The primary filter 12 intercepts larger dust particles, while the medium-efficiency filter 17 further filters fine dust particles. The high-efficiency filter 16 can filter micron-sized dust particles, thereby achieving deep purification of dust. The purified air is discharged through the front end of the fan 2. The outer side of the dust collection bin 1 is provided with a cover plate 4. The back side of the cover plate 4 is connected to the dust collection bin 1 by a hinge. The front side of the cover plate 4 is connected and fixed to the dust collection bin 1 by a buckle. Unfastening the buckle and opening the cover plate 4 makes it easy to clean the dust inside the dust collection bin 1. Multiple suction holes 15 are connected to the annular channel 13, and the multiple suction holes 15 are arranged in a ring array.

[0028] Please see Figure 3 and Figure 4 A rotating rod 10 is rotatably connected to the inner top wall of the dust collection bin 1. The bottom end of the rotating rod 10 passes through the middle of the high-efficiency filter 16, the medium-efficiency filter 17, and the primary filter 12 from top to bottom. The rotating rod 10 can rotate in the middle of the high-efficiency filter 16, the medium-efficiency filter 17, and the primary filter 12, and the bottom end of the rotating rod 10 extends to the bottom of the primary filter 12. Dust collection ports 18 are opened on both the medium-efficiency filter 17 and the primary filter 12. A double-sided brush 20 and a brush body 11 are fixedly connected to the outside of the rotating rod 10. A motor 3 for driving the rotating rod 10 to rotate is fixedly connected to the top of the dust collection bin 1. The operation of the motor 3 drives the rotating rod 10 to rotate, and the rotation of the rotating rod 10 drives the double-sided brush 20, the brush body 11, and the sealing plate 21 to rotate. The brush body 11 rotates to clean the bottom of the high-efficiency filter 16, medium-efficiency filter 17, and pre-filter 12. Meanwhile, the bristles 202 on the bottom side of the double-sided brush 20 sweep away the dust brushed down by the double-sided brush 20, preventing dust from falling onto the top of the pre-filter 12 and medium-efficiency filter 17. When the double-sided brush 20 rotates to the dust collection port 18, the dust swept down by the rotation falls into the lower part of the dust collection bucket 1 through the dust collection port 18, thereby collecting the cleaned dust. There are two double-sided brushes 20. The two double-sided brushes 20 are respectively set on the upper and lower sides of the medium-efficiency filter 17, and the opposite sides of the two double-sided brushes 20 are in contact with the opposite sides of the high-efficiency filter 16 and the pre-filter 12, respectively. The brush body 11 is set at the bottom of the pre-filter 12.

[0029] Please see Figure 3 and Figure 4 Both the primary filter 12 and the secondary filter 17 are fixedly connected to baffles 19. When the double-sided brush 20 is used to rotate and clean the high-efficiency filter 16 and the secondary filter 17, the swept dust falls into the lower part of the dust collection bin 1 through the dust inlet 18 to collect the dust. The baffles 19 block the falling dust and prevent it from falling on the top of the secondary filter 17 and the primary filter 12. The surface of the baffles 19 is at the same level as the inner wall of the dust inlet 18.

[0030] Please see Figure 3 and Figure 4The height of the baffle 19 at the top of the primary filter 12 is lower than the height of the baffle 19 at the top of the secondary filter 17. Both the secondary filter 17 and the primary filter 12 are provided with sealing plates 21 at their bottoms and corresponding to the dust inlet 18. The two sealing plates 21 are fixedly connected to the double-sided brush 20 and the brush body 11, respectively. The sealing plate 21 at the bottom of the secondary filter 17 passes through the gap between the baffle 19 and the secondary filter 17 and is fixedly connected to the double-sided brush 20. During filtration, the two sealing plates 21 block the dust inlet 18. The double-sided brush 20 includes a brush handle 201, and the upper and lower ends of the brush handle 201 are provided with bristles 202. The brush body 11 includes a brush handle 2, and the inner side of the brush handle 2 is provided with bristles 2. Both the brush handle 201 and the brush handle 2 are fixedly connected to the outer wall of the rotating rod 10.

[0031] The implementation principle of this application embodiment is as follows: the fan 2 is controlled to work through the connection pipe 5, hose 6, annular pipe 8, annular channel 13, dust inlet 14 and dust inlet 15 to suck up dust, thereby collecting the dust into the dust collection bin 1. The multiple dust inlets 15, together with the dust inlet 14, increase the dust suction area. The dust is filtered in multiple stages through the cooperation of the primary filter 12, medium-efficiency filter 17 and high-efficiency filter 16. The primary filter 12 intercepts larger dust particles, the medium-efficiency filter 17 further filters fine dust particles, and the high-efficiency filter 16 can filter micron-sized dust particles, thereby achieving deep purification of dust. The purified air is discharged through the front end of the fan 2.

[0032] The control motor 3 drives the rotating rod 10 to rotate, which in turn drives the double-sided brush 20, brush body 11, and sealing plate 21 to rotate. The double-sided brush 20 and brush body 11 rotate to clean the bottom of the high-efficiency filter 16, medium-efficiency filter 17, and primary filter 12. Meanwhile, the bristles 202 on the bottom side of the double-sided brush 20 sweep away the dust brushed down by the double-sided brush 20, preventing dust from falling onto the top of the primary filter 12 and medium-efficiency filter 17. When the double-sided brush 20 rotates to the dust collection port 18, the dust swept down by the rotation falls through the dust collection port 18 into the lower part of the dust collection bin 1, thereby collecting the cleaned dust. The cover plate 4 is then opened to facilitate cleaning the dust inside the dust collection bin 1.
