[0012] A usage method in paint spraying, which applies a trolley for moving paint cans. The specific steps are as follows: When the trolley body works and needs to move, the transmission member operates, enabling power transmission between the wheels and the material transportation group. That is, when the trolley body moves forward, the transmission member operates, driving the material transportation group in the storage bin and the spraying bin to operate simultaneously. The paint in the storage bin is transported to the spraying bin through the material transportation group, and is sprayed externally through the spraying bin. When the trolley body does not move, the transmission member and the material transportation group do not operate simultaneously, so that the paint in the storage bin cannot be transported to the spraying bin, and the paint in the spraying bin cannot be sprayed outwards. When the trolley body does not work and needs to move, the transmission member operates, making it impossible to have power transmission between the wheels and the material transportation group. Thus, when the wheels rotate, the material transportation group cannot operate. When it is necessary to replace the paint in the spraying bin, the driving source drives multiple storage bins to rotate. At this time, the material transportation group no longer rotates, so that the paint in each storage bin cannot move outwards. Then, the storage bin containing the required paint is rotated to the top of the spraying bin, and the outlet of the storage bin coincides with the inlet of the spraying bin, thus completing the replacement of the paint. Beneficial effects

[0013] Compared with the prior art, the present invention provides a trolley for moving paint cans and a usage method in paint spraying, having the following beneficial effects: 1. A trolley for moving paint cans and a usage method in paint spraying. Through the setting that the outlets of multiple storage bins coincide with the inlets of the spraying bin and the setting of the material transportation group, when the trolley body stops moving, the material transportation group no longer operates, so that the spraying bin no longer sprays paint outwards, and the storage bin no longer transports paint into the spraying bin. At this time, through the setting of the driving source, multiple storage bins are driven to rotate, so that the paint can containing the required paint is located on top of the spraying bin, thus quickly replacing the paint in the spraying bin, and solving the problem that when a paint trolley needs to spray different pigments on the ground, it is difficult to frequently replace the paint cans and it is difficult to achieve fast paint replacement operation during the work of the paint trolley.

[0014] 2. A trolley for moving paint cans and a method of using the same in paint spraying. Through the engagement between the clamping block and the clamping groove, the operation of the spraying chamber can be quickly switched when the wheels rotate. By driving the movement of the gear with the baffle, the connection between the clamping block and the clamping groove is controlled. Thus, when the clamping block is connected to the clamping groove, the wheels rotate, driving the transmission member to operate. Then, through the transmission member, the rotation of the material conveying group is controlled, so that the spraying chamber sprays externally through the spraying head. When the baffle drives the gear to move in the reverse direction, the clamping block is separated from the clamping groove. When the wheels rotate, the movable rotating cylinder connecting the clamping block no longer rotates due to the rotation of the first rotating rod. As a result, the wheels cannot drive the material conveying group to operate, and when the trolley body moves, the spraying chamber cannot spray paint externally through the spraying head. Thus, the effect that the two states of the spraying chamber working and no longer spraying paint externally can be quickly switched during the movement of the trolley body is achieved.

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] As introduced in the background art, there are deficiencies in the prior art. To solve the above technical problems, the present application proposes a trolley for moving a paint can and a usage method in paint spraying. Embodiment 1:

[0019] Please refer to Figures 1 - 3 , a trolley for moving a paint can, including a trolley body 1. The trolley body 1 includes a carriage board 101 and wheels 102 located at the four corners of the bottom of the carriage board 101. A spraying bin 2 is fixedly installed on the top of the carriage board 101, and a plurality of storage bins 3 are arranged on the top of the spraying bin 2; The spraying bin 2 is communicated with a single storage bin 3, and a material conveying group 4 is arranged at the discharge ports of the spraying bin 2 and the storage bin 3, so that when the material conveying group 4 rotates, the openings of the spraying bin 2 and the storage bin 3 discharge materials synchronously; A transmission part 5 is arranged between the wheels 102 and the spraying bin 2, so that when the wheels 102 rotate, the transmission part 5 is driven to operate, thereby driving the rotation of the material conveying group 4; A driving source 6 is installed on multiple storage bins 3, and the driving source 6 drives the multiple storage bins 3 to rotate so that the discharge port of a single storage bin 3 coincides with the feed port of the spraying bin 2.

[0020] Specifically, when the trolley body 1 is working and needs to move, the transmission member 5 operates, enabling power transmission between the wheels 102 and the material conveying group 4. That is, when the trolley body 1 moves forward, the transmission member 5 operates, driving the material conveying group 4 in both the storage bin 3 and the spraying bin 2 to operate simultaneously. The material conveying group 4 transports the paint in the storage bin 3 into the spraying bin 2 and sprays it externally through the spraying bin 2. When the trolley body 1 does not move, the transmission member 5 and the material conveying group 4 both stop operating, so that the paint in the storage bin 3 cannot be transported into the spraying bin 2, and the paint in the spraying bin 2 cannot be sprayed outwards. When the trolley body 1 is not working and needs to move, the transmission member 5 operates, preventing power transmission between the wheels 102 and the material conveying group 4. Thus, when the wheels 102 rotate, the material conveying group 4 cannot operate. When the paint in the spraying bin 2 needs to be replaced, the driving source 6 drives the multiple storage bins 3 to rotate. At this time, the material conveying group 4 no longer rotates, so that the paint in each storage bin 3 cannot move outwards. Then, the storage bin 3 containing the required paint is rotated onto the spraying bin 2, and the outlet of the storage bin 3 coincides with the inlet of the spraying bin 2, thus completing the replacement of the paint. Through the setting where the outlets of the multiple storage bins 3 coincide with the inlets of the spraying bin 2 and the setting of the material conveying group 4, when the trolley body 1 stops moving, the material conveying group 4 no longer operates. As a result, the spraying bin 2 no longer sprays paint outwards, and the storage bin 3 no longer transports paint into the spraying bin 2. At this time, through the setting of the driving source 6, the multiple storage bins 3 are driven to rotate, so that the storage tank containing the paint to be used is located at the top of the spraying bin 2, thus quickly replacing the paint in the spraying bin 2. This solves the problem that when a paint trolley needs to spray different pigments on the ground, it is necessary to frequently replace the paint tank, and it is difficult to achieve a quick paint replacement operation when the paint trolley is working. Embodiment 2:

[0021] The difference from the above Embodiment 1 is as follows. Refer to Figures 1 - 4 For the above spraying bin 2 and storage bin 3, the spraying bin 2 is fixedly installed on the top of the vehicle board 101, and the bottom of the spraying bin 2 extends to the bottom of the vehicle board 101. Multiple spraying nozzles 7 are provided at the bottom of the spraying bin 2, and the spraying nozzles 7 are fixedly connected to the spraying bin 2 through one-way valves. Vertical plates 8 are fixedly connected to both sides of the top of the vehicle board 101. The driving source 6 includes a servo motor 61, and the servo motor 61 is fixedly installed on one of the vertical plates 8. A rotating rod 9 is rotatably connected between the two vertical plates 8 through bearings. One end of the rotating rod 9 is fixedly connected to the output end of the servo motor 61, and multiple connecting plates 10 are fixedly connected to the outer periphery of the rotating rod 9. The connecting plates 10 are fixedly connected to the storage bin 3. The wheel 102 is fixedly installed at the bottom of the vehicle board 101 through a bearing seat. A connecting rod 11 is fixedly connected between two wheels 102. A tooth groove 13 is formed on the outer circumference of the connecting rod 11. A toothed belt 12 is sleeved on the outer circumferences of the two connecting rods 11. The toothed belt 12 is meshed and connected with the connecting rod 11 through the tooth groove 13. Specifically, when the spraying chamber 2 is working, the trolley body 1 moves, thereby driving the wheel 102 to rotate. When the wheel 102 rotates, through the setting of the transmission member 5, the material conveying group 4 at the outlet of the spraying chamber 2 and the outlet of the storage bin 3 operates simultaneously, so that the paint in the storage bin 3 is transported into the spraying chamber 2 through the material conveying group 4, and the paint in the spraying chamber 2 is transported to the spraying head 7 through the material conveying group 4, so that the paint is sprayed on the ground through the spraying head 7. When it is necessary to replace the paint in the spraying chamber 2, the trolley body 1 is stopped, so that the material conveying group 4 no longer operates, so that the paint in the storage bin 3 and the spraying chamber 2 cannot move outwards. At this time, through the setting of the driving source 6, multiple storage bins 3 are controlled to rotate, so that the storage bin 3 filled with the paint to be sprayed is located at the top of the spraying chamber 2, and the inlet of the spraying chamber 2 coincides with the outlet of the storage bin 3, so as to achieve the rapid replacement of the storage bin 3. Embodiment Three:

[0022] The difference from the above Embodiment Two lies in referring to Figures 1 - 4 , for the above-mentioned material conveying group 4, the material conveying group 4 includes a movable plate 41. Circular grooves are formed on both sides of the outlets of the spraying chamber 2 and the storage bin 3. A circular plate 42 is rotatably connected in the circular groove through a bearing. A circular rod 43 is fixedly connected between the two circular plates 42. A plurality of fixing plates 44 are fixedly connected to the outer circumference of the circular rod 43. A chute 45 is formed on the fixing plate 44. The movable plate 41 is slidably arranged in the chute 45. A rectangular groove 46 is formed on one side of the circular plate 42. Rectangular blocks 47 are fixedly connected to both sides of the movable plate 41. The rectangular blocks 47 are slidably arranged in the rectangular groove 46. A first spring 48 is fixedly connected to the bottom of the rectangular block 47. The top of the movable plate 41 is set as an arc surface. Specifically, when the transmission member 5 operates, it drives the circular plate 42 to rotate, thereby driving the fixed plate 44 fixedly connected to the circular plate 42 to rotate, and simultaneously driving the movable plate 41 slidably connected to the fixed plate 44 to rotate synchronously. When the top of the movable plate 41 rotates and contacts the inner wall of the storage bin 3 or the spraying bin 2, due to the setting of the arc surface at the top of the movable plate 41 and the setting of the slidable connection between the movable plate 41 and the fixed plate 44, the movable plate 41 moves towards the bottom of the chute 45. During the rotation of the movable plate 41 with the round rod 43 as the axis, the arc surface of the movable plate 41 always contacts the two side walls at the outlet of the storage bin 3 or the spraying bin 2, and the paint in the storage bin 3 or the spraying bin 2 is located between the two movable plates 41. When one of the movable plates 41 in front of the movable plate 41 moves to one side at the bottom of the outlet of the storage bin 3 or the spraying bin 2, the movable plate 41 no longer fits the inner wall of the storage bin 3 or the spraying bin 2, so that the paint between the two movable plates 41 moves downward. When the material transporting group 4 stops operating, the arc surfaces of the movable plates 41 on both sides of the round rod 43 always fit the two side walls at the outlet of the storage bin 3 or the spraying bin 2, so that the paint in the storage bin 3 or the spraying bin 2 cannot move outwards.

The vertical rod 523 extends to the top of the vehicle plate 101. A third worm 524 is fixedly connected to the vertical rod 523. One side of the spraying chamber 2 is rotatably connected through a bearing to a third connecting rod 525. One end of the third connecting rod 525 is fixedly connected to one of the circular plates 42 located inside the spraying chamber 2. The other end of the third connecting rod 525 is fixedly connected to a third worm gear 526. The third worm gear 526 is meshed and connected with the third worm 524; The transmission member 5 further includes a fourth worm 527 and a fourth worm gear 528. One side of the storage bin 3 is rotatably connected through a bearing to a fourth connecting rod 529. The fourth worm gear 528 is fixedly connected to one end of the fourth connecting rod 529. The other end of the fourth connecting rod 529 is fixedly connected to one of the circular plates 42 located inside the storage bin 3. One side of the storage bin 3 is rotatably connected to a vertical shaft 530 through a bearing seat. The fourth worm 527 is fixedly installed on the vertical shaft 530. A clamping block 531 is fixedly connected to the bottom of the vertical shaft 530. A clamping groove 532 is formed at the top of the vertical rod 523. The clamping block 531 is fitted with the clamping groove 532; Specifically, when the wheel 102 rotates, it drives the connecting rod 11 to rotate, thereby driving the first worm 52 to rotate. Through the meshing connection between the first worm 52 and the first worm gear 51, the first worm gear 51 is driven to rotate, thereby driving the first rotating rod 53 to rotate. Through the fitting between the card slot 54 and the block 512, the cross rod 510 is driven to rotate. Through the fitting between the cross rod 510 and the cross slot 59, the movable sleeve 57 is driven to rotate. Through the cooperation between the limiting block 58 in the movable sleeve 57 and the limiting slot 56 opened outside the second connecting rod 55, the second connecting rod 55 is driven to rotate, thereby driving the second worm 521 fixedly connected to the second connecting rod 55 to rotate. Through the meshing connection between the second worm 521 and the second worm gear 522, the second worm gear 522 is driven to rotate, thereby driving the vertical rod 523 to rotate, and further driving the third worm 524 on the vertical rod 523 to rotate. Through the meshing connection between the third worm 524 and the third worm gear 526, the material conveying group 4 in the spraying chamber 2 is driven to operate. At the same time, through the fitting between the positioning block 531 and the positioning slot 532, when the vertical rod 523 rotates, the vertical shaft 530 is driven to rotate, thereby driving the fourth worm 527 to rotate. Through the meshing connection between the fourth worm 527 and the fourth worm gear 528, the fourth worm gear 528 is driven to rotate, thereby driving the material conveying group 4 in the storage bin 3 to operate; When the wheel 102 rotates and the spraying chamber 2 does not need to work, the guide plate 519 is driven to move through the baffle 520, thereby driving the toothed plate 514 to move. Through the meshing connection between the toothed plate 514 and the gear 513, the gear 513 is driven to rotate, thereby driving the threaded rod 517 to rotate. Through the threaded connection between the threaded rod 517 and the threaded sleeve 515, the threaded sleeve 515 is driven to move backward. Due to the setting that the threaded sleeve 515 is fixedly connected to the movable sleeve 57 through the connecting plate 516, when the threaded sleeve 515 moves backward, the movable sleeve 57 is driven to move backward, so that the block 512 is separated from the card slot 54. Furthermore, when the wheel 102 drives the connecting rod 11 and the first rotating rod 53 to rotate, the subsequent second connecting rod 55 and the vertical rod 523 cannot be driven to rotate, so that when the wheel 102 rotates, the material conveying group 4 cannot be driven to operate; When the storage bin 3 needs to be replaced, the rotating rod 9 is driven to rotate through the servo motor 61, thereby driving the storage bin 3 to rotate. When one of the storage bins 3 rotates, the positioning block 531 at the bottom of the vertical shaft 530 is separated from the positioning slot 532 at the top of the vertical rod 523. When the other storage bin 3 rotates to the top of the spraying chamber 2, the positioning block 531 at the bottom of the vertical shaft 530 coincides with the positioning slot 532 at the top of the vertical rod 523, so that the material conveying group 4 inside the storage bin 3 is driven to operate through the transmission member 5. Embodiment Five:

[0024] Refer to Figures 1 - 12 , this embodiment discloses a usage method in paint spraying. The specific steps are as follows: When the cart body 1 is working and needs to be moved, the transmission member 5 operates, enabling power transmission between the wheels 102 and the material transportation group 4. That is, when the cart body 1 moves forward, the transmission member 5 operates, driving the material transportation group 4 in the storage bin 3 and the spraying bin 2 to operate simultaneously. Through the material transportation group 4, the paint in the storage bin 3 is transported into the spraying bin 2 and sprayed externally through the spraying bin 2. When the cart body 1 does not move, the transmission member 5 and the material transportation group 4 do not operate simultaneously, so that the paint in the storage bin 3 cannot be transported into the spraying bin 2, and the paint in the spraying bin 2 cannot be sprayed outward. When the cart body 1 is not working and needs to be moved, the transmission member 5 operates, preventing power transmission between the wheels 102 and the material transportation group 4. Thus, when the wheels 102 rotate, the material transportation group 4 cannot operate. When the paint in the spraying bin 2 needs to be replaced, the drive source 6 drives multiple storage bins 3 to rotate. At this time, the material transportation group 4 no longer rotates, so that the paint in each storage bin 3 cannot move outward, and the storage bin 3 containing the required paint is rotated onto the spraying bin 2, and the outlet of the storage bin 3 coincides with the inlet of the spraying bin 2, thus completing the replacement of the paint.

[0025] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
