The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0036] Example 1, referring to Figures 1 to 3 and Figures 5 to 7 This is the first embodiment of the present invention. This embodiment provides a renovation device for stadium seats, which can realize automatic liquid application and automatic sealing of coatings, and includes a frame 1.

[0037] Specifically, the painting assembly 2 is set inside the frame 1. The painting assembly 2 includes a partition guide 21 set inside the frame 1 and an automatic coating component 22 set at the end of the partition guide 21.

[0038] Furthermore, the internal connection of frame 1 includes a painting component 2;

[0039] The painting assembly 2 includes a partition guide 21. The partition guide 21 is connected to the inner top of the frame 1. The interior of the partition guide 21 is connected to the automatic coating component 22. The upper end of the automatic coating component 22 is connected to the frame 1.

[0040] Specifically, the partitioned material guide 21 includes a material holding box 211 disposed inside the frame 1 and a first material guide plate 213 disposed at the end of the material holding box 211;

[0041] The end of the material container 211 is provided with a second guide plate 214;

[0042] Furthermore, the automatic coating component 22 includes a material container 211, which is slidably connected to the inner top of the frame 1. A set of first guide plates 213 are fixedly connected to both sides of the bottom of the material container 211, and the lower ends of the two sets of first guide plates 213 are inclined towards each other.

[0043] Specifically, the automatic coating component 22 includes an arc-shaped wall 222 disposed at the end of the first guide plate 213 and a coating roller 223 disposed at the end of the material container 211;

[0044] Furthermore, the automatic coating component 22 includes an arc-shaped wall 222. The lower ends of the two sets of first guide plates 213 are provided with arc-shaped walls 222 on the side that are close to each other. A paint roller 223 is rotatably connected between the front and rear inner walls of the material container 211 between the two sets of arc-shaped walls 222. The paint roller 223 is in contact with the arc-shaped wall 222.

[0045] The paint roller 223 moves upward and rolls after it detaches from the arc-shaped wall 222;

[0046] Specifically, the partition guide component 21 also includes a partition 212. The material holding box 211 is provided with a partition 212, and a second guide plate 214 is provided at the lower end of the partition 212.

[0047] Furthermore, the partition guide component 21 also includes a partition 212. Two sets of partitions 212 are fixedly connected inside the material container 211. The partitions 212 divide the upper end of the material container 211 into three different sections. A set of second guide plates 214 are fixedly connected to the bottom of each partition 212. The second guide plates 214 are inclined towards the paint roller 223 and are slidably connected to the paint roller 223.

[0048] Specifically, the automatic coating component 22 also includes a material passage 221. The lower end of the second guide plate 214 is provided with a material passage 221, and the material holding box 211 at the end of the coating roller 223 is provided with a relief groove 224. The end of the rotating shaft of the coating roller 223 is located in the relief groove 224.

[0049] Furthermore, the automatic coating component 22 also includes a material passage 221. The lower end of the second guide plate 214 is provided with a material passage 221. The inner wall of the material collection box 211 on both sides of the coating roller 223 is provided with a relief groove 224. The rotating shaft of the coating roller 223 is rotatably connected to the relief groove 224.

[0050] The clearance groove 224 is in the shape of a slot;

[0051] When the paint roller 223 rises to contact the second guide plate 214, the paint roller 223 disengages from the arc-shaped wall 222, and at this time the rotation axis of the paint roller 223 is located at the upper end of the relief groove 224.

[0052] In use, paint is added into the container 211, and then the container 211 is placed on the bench. The bench then presses the paint roller 223 upwards. The paint roller 223 moves upwards under the limit of the relief groove 224. When the paint roller 223 moves to contact the second guide plate 214, the paint roller 223 disengages from the arc wall 222, thus creating a gap between the paint roller 223 and the arc wall 222. At this time, the paint in the container 211 flows out through the gap between the paint roller 223 and the arc wall 222 under the guidance of the first guide plate 213. The paint between the second guide plates 214 flows onto the paint roller 223 through the passage groove 221. Then, the container 211 is moved, and the container 211 drives the paint roller 223 to roll on the bench, thereby coating and refurbishing the bench through the paint roller 223, thus realizing the automatic discharge and coating of paint.

[0053] When the coating is completed, the material container 211 and the paint roller 223 are moved away from the long bench. At this time, under the pressure of the gravity of the paint roller 223 and the paint in the material container 211, the roller 223 moves downward and fits against the curved wall 222, thereby automatically sealing the opening between the first guide plates 213. This achieves the sealing of the remaining paint at the same time as the coating is completed, avoiding the contamination of the seat by the remaining paint and reducing paint waste.

[0060] Furthermore, the material handling component 31 includes a base plate 311. The base plate 311 is fixedly connected to the inner wall of the material container 211 at the lower end of the partition 212. The base plate 311 separates the upper and lower parts of the material container 211. Three rows of first material handling holes 312 with equal spacing are opened on the base plate 311 on both sides of the partition 212, and the three rows of first material handling holes 312 on both sides of the partition 212 are staggered.

A baffle slide plate 3 is fixedly connected to the switching slide plate 313 inside the partition 212. 15. The material blocking slide plate 315 is slidably connected inside the partition plate 212 and both ends of the material blocking slide plate 315 extend beyond the switching slide plate 313. Three rows of second material passage holes 314 with the same spacing are opened on the switching slide plates 313 on both sides of the material blocking slide plate 315 and the three rows of second material passage holes 314 on both sides of the material blocking slide plate 315 are aligned with each other. A guide rod 316 is fixedly connected to the side wall of the switching slide plate 313. The guide rod 316 passes through the side wall of the material box 211 and is slidably connected to the partition plate 212. A spring 317 is fixedly connected between the end of the guide rod 316 away from the switching slide plate 313 and the outer wall of the material box 211.

[0061] Specifically, the partition 212 divides the internal space of the material box 211 above the base plate 311 into several sections. The first material passage holes 312 on the base plate 311 in two adjacent sections are staggered. The second material passage holes 314 on the switching slide plate 313 correspond one-to-one with the first material passage holes 312 on the base plate 311. The second material passage holes 314 on both sides of the baffle slide plate 315 are flush with each other.

[0062] Furthermore, the spacing between two adjacent rows of first feed holes 312 on the same side of the partition 212 is three times the vertical distance between two adjacent rows of first feed holes 312 on both sides of the partition 212.

[0063] Specifically, the adjustable limiting member 32 includes a limiting rod 321. The end of the switching slide plate 313 is provided with a limiting rod 321. The end of the frame 1 is provided with a fixed limiting plate 322. A first sliding limiting plate 323 is provided above the fixed limiting plate 322. A second sliding limiting plate 324 is provided above the first sliding limiting plate 323. A third sliding limiting plate 325 is provided above the second sliding limiting plate 324.

[0064] Furthermore, the adjustable limiting component 32 includes a limiting rod 321. The limiting rod 321 is fixedly connected to the top of the switching slide plate 313. A fixed limiting plate 322 is fixedly connected to the middle position of the inner wall of the upper end of the frame 1 near the limiting rod 321. A set of first sliding limiting plates 323 are slidably connected to both ends of the top of the fixed limiting plate 322. A second sliding limiting plate 324 is slidably connected to the top of each of the first sliding limiting plates 323. A third sliding limiting plate 325 is slidably connected to the top of each of the second sliding limiting plates 324. The ends of the first sliding limit plate 323, the second sliding limit plate 324, and the third sliding limit plate 325 near the frame 1 are all slidably connected to the frame 1. The ends of the first sliding limit plate 323, the second sliding limit plate 324, and the third sliding limit plate 325 that are far from each other are all slopes. The limiting rod 321 is slidably connected to the side wall of the fixed limit plate 322, the first sliding limit plate 323, the second sliding limit plate 324, and the third sliding limit plate 325 that are far from the frame 1.

[0065] The width of the third sliding limit plate 325 is the same as the vertical distance between the two adjacent rows of first material passage holes 312 on both sides of the partition plate 212. The width of the second sliding limit plate 324 is twice the width of the third sliding limit plate 325. The width of the first sliding limit plate 323 is three times the width of the third sliding limit plate 325. The width of the first sliding limit plate 323 is the same as the width of the fixed limit plate 322.

[0066] When the limiting rod 321 slides on the side wall of the third sliding limiting plate 325, the first material passage hole 312 on the left side of the left partition 212 is aligned with the second material passage hole 314 above it, and the remaining first material passage holes 312 are offset from the second material passage hole 314. When the limiting rod 321 slides on the side wall of the second sliding limiting plate 324, the first material passage hole 312 between the two sets of partitions 212 is aligned with the second material passage hole 314 above it, and the remaining first material passage holes 312 are offset from the second material passage hole 314. When the limiting rod 321 slides on the side wall of the first sliding limiting plate 323 and the fixed limiting plate 322, the first material passage hole 312 on the right side of the first material passage hole 312 is aligned with the second material passage hole 314 above it, and the remaining first material passage holes 312 are offset from the second material passage hole 314. When the limiting rod 321 slides on the inner wall of the frame 1, all the first material passage holes 312 are offset from the second material passage hole 314.

[0067] The third sliding limit plate 325 corresponds to the leftmost storage area, the second sliding limit plate 324 corresponds to the middle storage area, and the first sliding limit plate 323 and the fixed limit plate 322 correspond to the rightmost storage area.

[0068] Specifically, the internal structure of frame 1 contains a driver 4;

[0069] The driving component 4 includes a motor 41. The motor 41 is provided at the end of the frame 1, and a threaded rod 42 is provided at the end of the motor 41. The end of the threaded rod 42 passes through the material container 211 and is provided on the frame 1.

[0070] Furthermore, the internal connections of frame 1 include a driving element 4;

[0071] The driving component 4 includes a motor 41. One end of the frame 1 is fixedly connected to the motor 41. The output end of the motor 41 is fixedly connected to a threaded rod 42. The other end of the threaded rod 42 is rotatably connected to the frame 1. The middle part of the material box 211 is fixedly connected to a threaded sleeve 43. The threaded rod 42 passes through the threaded sleeve 43 and is threadedly connected to the threaded sleeve 43.

[0072] In use, when it is necessary to repaint a bench with different color zones, different colors of paint are fed into the different zones on both sides of the partition 212. The third sliding limit plate 325, the second sliding limit plate 324, and the first sliding limit plate 323 are slid until their ends are at the junctions of the different color zones and are fixed with bolts. At this time, the motor 41 is started. The motor 41 drives the material container 211 to move along the direction of the bench through the threaded rod 42 and the threaded sleeve 43. The material container 211 simultaneously drives the limit rod 321 to move. When the limit rod 321 slides onto the third sliding limit plate 325, the limit rod 321 drives the first sliding limit plate 323 to move backward by a distance equivalent to the width of the third sliding limit plate 325. At this time, the first material passage hole 312 of the leftmost material storage zone is connected to the second material passage hole 314, while the first material passage holes 312 and second material passage holes 314 in the other material storage zones are not connected. This ensures that only the paint in the leftmost zone flows. The long bench is coated and refurbished under the guidance of the first guide plate 213 and below the bottom plate 311. When the limiting rod 321 moves to the ramp at the end of the second sliding limiting plate 324, the limiting rod 321 drives the switching slide plate 313 to continue moving backward. At this time, the left storage area is gradually blocked while the paint under the bottom plate 311 is slowly coated. When the limiting rod 321 moves to the side wall of the second sliding limiting plate 324, the middle storage area and the bottom of the bottom plate 311 are connected and the storage areas on the left and right sides are blocked. At this time, the paint in the middle storage area is used to coat and refurbish the long bench. Thus, the paint can be automatically switched by simply placing the end of the second sliding limiting plate 324 at the junction of the two color areas. Similarly, when the limiting rod 321 moves to the fixed limiting plate 322 and the side wall of the fixed limiting plate 322, the paint in the rightmost storage area is used to coat and refurbish the long bench with different color areas.

[0073] When it is necessary to renovate a bench with only one or two color ranges, one or both of the third sliding limit plate 325 and the second sliding limit plate 324 can be completely closed above the first sliding limit plate 323 or the fixed limit plate 322. When it is necessary to renovate a bench with multiple color ranges, it is only necessary to simultaneously increase the material storage area and the second sliding limit plate 324 or the third sliding limit plate 325 and simultaneously increase the distance between the adjacent two rows of first material passage holes 312 and second material passage holes 314. When the coating is completed, the limit rod 321 only needs to move to contact the inner wall of the frame 1. At this time, all the material storage areas are in a blocked state, realizing the automatic sealing of the paint after the coating is completed.

[0074] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
