Beneficial effects

[0018] Compared with the prior art, the present invention provides a trolley for moving paint cans and a method for using the trolley in paint spraying, which has the following beneficial effects:

A trolley for moving paint cans and a method of using the trolley in paint spraying, wherein the outlets of multiple material storage bins are matched with the inlet of the spray bin, and the material transport group is set, so that when the trolley body stops moving, the material transport group stops running, so that the spray bin no longer sprays paint outward, and the material storage bin no longer transports paint into the spray bin. At this time, the driving source is set to drive the multiple material storage bins to rotate, so that the material storage tanks containing the paint to be used are located on the top of the spray bin, so that the paint in the spray bin can be quickly replaced, which solves the problem that when the paint trolley needs different pigments to spray the ground, the paint cans need to be frequently replaced, and it is difficult to realize the rapid material replacement operation of the paint trolley when working.

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] As introduced in the background technology, there are deficiencies in the existing technology. In order to solve the above technical problems, the present application proposes a trolley for moving paint cans and a method for using the trolley in paint spraying. Example 1:

[0036] See also Figure 1-Figure 3 A trolley for moving paint tanks includes a trolley body 1, the trolley body 1 includes a vehicle plate 101 and wheels 102 located at the four corners of the bottom of the vehicle plate 101, a spraying bin 2 is fixedly mounted on the top of the vehicle plate 101, and a plurality of material storage bins 3 are provided on the top of the spraying bin 2;

[0037] The spraying bin 2 is connected to a single material storage bin 3. A material transport group 4 is provided at the material outlet of the spraying bin 2 and the material storage bin 3, so that when the material transport group 4 rotates, the material is discharged synchronously at the openings of the spraying bin 2 and the material storage bin 3;

[0038] A transmission member 5 is provided between the wheel 102 and the spray chamber 2, so that when the wheel 102 rotates, the transmission member 5 is driven to operate, thereby driving the rotation of the material transport group 4;

[0039] A driving source 6 is installed on the 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 spray bin 2 .

[0040] Specifically, when the cart body 1 is working and needs to move, the transmission member 5 operates, so that the power is transmitted between the wheel 102 and the material transport group 4, that is, when the cart body 1 moves forward, the transmission member 5 operates, driving the storage bin 3 and the material transport group 4 in the spray bin 2 to operate at the same time, and the paint in the storage bin 3 is transported to the spray bin 2 through the material transport group 4, and is sprayed externally through the spray bin 2. When the cart body 1 does not move, the transmission member 5 and the material transport group 4 do not operate at the same time, so that the paint in the storage bin 3 cannot be transported to the spray bin 2, and the paint in the spray bin 2 cannot be sprayed outward When the trolley body 1 is not working and needs to be moved, the transmission member 5 operates, so that the power transmission between the wheel 102 and the material transport group 4 cannot be carried out, so that when the wheel 102 rotates, the material transport group 4 cannot operate. When the paint in the spraying bin 2 needs to be replaced, the multiple storage bins 3 are driven to rotate by the driving source 6. At this time, the material transport group 4 no longer rotates, so that the paint in each storage bin 3 cannot be moved outward, so that the storage bin 3 filled with the required paint is rotated to the spraying bin 2, and the outlet of the storage bin 3 coincides with the inlet of the spraying bin 2, thereby completing the replacement of the paint;

[0041] By arranging that the outlets of multiple storage bins 3 coincide with the inlets of the spray bin 2, and by arranging the material transport group 4, when the cart body 1 stops moving, the material transport group 4 no longer runs, so that the spray bin 2 no longer sprays paint outward, and the storage bin 3 no longer transports paint into the spray bin 2. At this time, by arranging 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 on the top of the spray bin 2, so that the paint in the spray bin 2 can be quickly replaced, which solves the problem that when the paint cart needs different pigments to spray the ground, the paint tank needs to be replaced frequently, and it is difficult to realize the rapid material replacement operation of the paint cart when working. Example 2:

[0042] The difference from the above embodiment 1 is that, see Figures 1-4 , for the above-mentioned spraying bin 2 and storage bin 3, the spraying bin 2 is fixedly mounted on the top of the vehicle plate 101, and the bottom of the spraying bin 2 extends to the bottom of the vehicle plate 101. A plurality of spray heads 7 are provided at the bottom of the spraying bin 2, and the spray heads 7 are fixedly connected to the spraying bin 2 through a one-way valve;

[0043] Both sides of the top of the vehicle plate 101 are fixedly connected to vertical plates 8, and the driving source 6 includes a servo motor 61, which is fixedly mounted on one of the vertical plates 8. A rotating rod 9 is rotatably connected between the two vertical plates 8 through a bearing, and one end of the rotating rod 9 is fixedly connected to the output end of the servo motor 61. A plurality of connecting plates 10 are fixedly connected to the outer periphery of the rotating rod 9, and the connecting plates 10 are fixedly connected to the storage bin 3;

[0044] The wheels 102 are fixedly mounted on the bottom of the vehicle plate 101 via bearing seats, wherein a connecting rod 11 is fixedly connected between the two wheels 102, and a tooth groove 13 is formed on the outer periphery of the connecting rod 11. A tooth belt 12 is sleeved on the outer periphery of the two connecting rods 11, and the tooth belt 12 is meshed with the connecting rod 11 through the tooth groove 13;

[0045] Specifically, when the spraying bin 2 is working, the cart body 1 moves, thereby driving the wheels 102 to rotate. When the wheels 102 rotate, the material transporting groups 4 at the outlet of the spraying bin 2 and the outlet of the storage bin 3 are driven to run simultaneously through the setting of the transmission member 5, so that the paint in the storage bin 3 is transported to the spraying bin 2 through the material transporting group 4, and the paint in the spraying bin 2 is transported to the spray head 7 through the material transporting group 4, so that the paint is sprayed on the ground through the spray head 7. When the paint in the spraying bin 2 needs to be replaced, the cart body 1 is stopped, so that the material transporting group 4 no longer runs, so that the paint in the storage bin 3 and the spraying bin 2 cannot move outward. At this time, through the setting of the driving source 6, the rotation of multiple storage bins 3 is controlled, so that the storage bin 3 filled with the paint to be sprayed is located at the top of the spraying bin 2, and the inlet of the spraying bin 2 is consistent with the outlet of the storage bin 3, thereby achieving rapid replacement of the storage bin 3. Example 3:

[0046] The difference from the above embodiment 2 is that, see Figures 1-4 , for the above-mentioned material transport group 4, the material transport group 4 includes a movable plate 41, circular grooves are opened on both sides of the outlets of the spraying bin 2 and the storage bin 3, and a circular plate 42 is rotatably connected to the circular groove through a bearing, a round rod 43 is fixedly connected between the two circular plates 42, and a plurality of fixed plates 44 are fixedly connected to the outer periphery of the round rod 43, a slide groove 45 is opened on the fixed plate 44, and the movable plate 41 is slidably set in the slide groove 45, and a rectangular groove 46 is opened on one side of the circular plate 42. Rectangular blocks 47 are fixedly connected on both sides of the movable plate 41, and the rectangular blocks 47 are slidably set in the rectangular groove 46. A first spring 48 is fixedly connected to the bottom of the rectangular block 47, and the top of the movable plate 41 is set to an arc surface;

[0047] Specifically, when the transmission member 5 is in operation, it drives the circular plate 42 to rotate, thereby driving the fixed plate 44 fixedly connected to the circular plate 42 to rotate, and at the same time drives 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 spray bin 2, the movable plate 41 moves to the bottom of the slide groove 45 through the setting of the arc surface at the top of the movable plate 41 and the setting of the sliding connection between the movable plate 41 and the fixed plate 44. During the rotation of the movable plate 41 with the round rod 43 as the axis, the arc surface of the movable plate 41 is always in contact with the outlet of the storage bin 3 or the spray bin 2 The two side walls are in contact with each other, and the paint in the storage bin 3 or the spray bin 2 is located between the two movable plates 41. When the movable plate 41 in front of one of the movable plates 41 moves to the bottom side of the outlet of the storage bin 3 or the spray bin 2, the movable plate 41 is no longer in contact with the inner wall of the storage bin 3 or the spray bin 2, so that the paint between the two movable plates 41 moves downward. When the material transport group 4 is no longer running, the curved surfaces of the movable plates 41 on both sides of the round rod 43 are always in contact with the two side walls of the outlet of the storage bin 3 or the spray bin 2, so that the paint in the storage bin 3 or the spray bin 2 cannot move outward.

[0049] The transmission member 5 also includes a gear 513 and a tooth plate 514. A threaded sleeve 515 is slidably provided at the bottom of the car plate 101 through a bearing seat.

One end of the threaded rod 517 is provided in the threaded sleeve 515 and is threadedly connected to the threaded sleeve 515. The gear 513 is fixedly installed on the other end of the threaded rod 517. A guide groove 518 is provided on one side of the car plate 101. A guide plate 519 is fixedly connected to the top of the tooth plate 514. The guide plate 519 is slidably provided in the guide groove 518. The tooth plate 514 is meshed with the gear 513. A baffle 520 is fixedly connected to one side of the guide plate 519.

[0050] The transmission member 5 also includes a second worm 521 and a second worm wheel 522. The bottom of the vehicle plate 101 is rotatably connected to a vertical rod 523 through a bearing seat. The second worm wheel 522 is fixedly mounted on the vertical rod 523. The second worm 521 is fixedly mounted on the second connecting rod 55. The second worm wheel 522 is meshed with the second worm 521. 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 spray chamber 2 is rotatably connected to a third connecting rod 525 through a bearing. One end of the third connecting rod 525 is fixedly connected to one of the circular plates 42 located in the spray chamber 2. The other end of the third connecting rod 525 is fixedly connected to a third worm wheel 526. The third worm wheel 526 is meshed with the third worm 524.

[0051] The transmission member 5 also includes a fourth worm 527 and a fourth worm wheel 528. One side of the storage bin 3 is rotatably connected to a fourth connecting rod 529 through a bearing. The fourth worm wheel 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 in 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 mounted on the vertical shaft 530. A positioning block 531 is fixedly connected to the bottom of the vertical shaft 530. A positioning groove 532 is provided at the top of the vertical rod 523, and the positioning block 531 is consistent with the positioning groove 532.

[0052] Specifically, when the wheel 102 rotates, the connecting rod 11 is driven to rotate, thereby driving the first worm 52 to rotate, and the meshing connection between the first worm 52 and the first worm wheel 51 drives the first worm wheel 51 to rotate, thereby driving the first rotating rod 53 to rotate, and the fit between the card slot 54 and the card block 512 drives the cross rod 510 to rotate, and the fit between the cross rod 510 and the cross slot 59 drives the movable sleeve 57 to rotate, and the fit between the limit block 58 in the movable sleeve 57 and the limit slot 56 on the outside of the second connecting rod 55 drives the second connecting rod 55 to rotate, thereby driving the second worm 521 fixedly connected to the second connecting rod 55 to rotate, and through the first The meshing connection between the second worm 521 and the second worm wheel 522 drives the second worm wheel 522 to rotate, thereby driving the vertical rod 523 to rotate, and then driving the third worm 524 on the vertical rod 523 to rotate. The meshing connection between the third worm 524 and the third worm wheel 526 drives the material transport group 4 in the spraying bin 2 to operate. At the same time, the fit between the positioning block 531 and the positioning groove 532 makes it possible for the vertical rod 523 to rotate, thereby driving the fourth worm 527 to rotate. The meshing connection between the fourth worm 527 and the fourth worm wheel 528 drives the fourth worm wheel 528 to rotate, thereby driving the material transport group 4 in the storage bin 3 to operate;

[0053] When the wheel 102 rotates and the spray chamber 2 is no longer needed to work, the guide plate 519 is driven to move by the baffle 520, thereby driving the tooth plate 514 to move. The meshing connection between the tooth plate 514 and the gear 513 drives the gear 513 to rotate, thereby driving the threaded rod 517 to rotate. The threaded connection between the threaded rod 517 and the threaded sleeve 515 drives the threaded sleeve 515 to move backward. Since the threaded sleeve 515 is fixedly connected to the movable sleeve 57 through the connecting plate 516, the threaded sleeve 515 moves backward, thereby driving the movable sleeve 57 to move backward, thereby separating the clamping block 512 from the clamping groove 54, and then making the wheel 102 drive the connecting rod 11 and the first rotating rod 53 to rotate, unable to drive the subsequent second connecting rod 55 and the vertical rod 523 to rotate, so that when the wheel 102 rotates, it cannot drive the material transport group 4 to operate;

[0054] When the storage bin 3 needs to be replaced, the servo motor 61 drives the rotating rod 9 to rotate, thereby driving the storage bin 3 to rotate. When one storage bin 3 rotates, the locking block 531 at the bottom of the vertical axis 530 is separated from the locking groove 532 at the top of the vertical rod 523. When the other storage bin 3 rotates to the top of the spray bin 2, the locking block 531 at the bottom of the vertical axis 530 coincides with the locking groove 532 at the top of the vertical rod 523, thereby driving the material transport group 4 inside the storage bin 3 to operate through the transmission part 5. Embodiment 5:

[0055] See Figures 1-12 This embodiment discloses a method for using the coating in spraying, and the specific steps are as follows:

[0056] When the trolley body 1 is working and needs to move, the transmission member 5 operates, so that the power is transmitted between the wheel 102 and the material transport group 4, that is, when the trolley body 1 moves forward, the transmission member 5 operates, driving the storage bin 3 and the material transport group 4 in the spray bin 2 to operate at the same time, and the paint in the storage bin 3 is transported to the spray bin 2 through the material transport group 4, and sprayed externally through the spray bin 2. When the trolley body 1 does not move, the transmission member 5 and the material transport group 4 do not operate at the same time, so that the paint in the storage bin 3 cannot be transported to the spray bin 2, and the paint in the spray bin 2 cannot be sprayed externally. When the cart body 1 is not working and needs to be moved, the transmission member 5 operates, so that power cannot be transmitted between the wheel 102 and the material transport group 4, so that when the wheel 102 rotates, the material transport group 4 cannot operate. When the paint in the spray bin 2 needs to be replaced, the multiple storage bins 3 are driven to rotate by the driving source 6. At this time, the material transport group 4 no longer rotates, so that the paint in each storage bin 3 cannot move outward, so that the storage bin 3 containing the required paint is rotated to the spray bin 2, and the outlet of the storage bin 3 is coincided with the inlet of the spray bin 2, thereby completing the replacement of the paint.
