[0018] The present invention is further described in detail below in conjunction with the accompanying drawings. Example

[0019] like Figure 1 , Figure 2 As shown, a wall latex paint spraying structure includes a workbench 01, a spray rod 02, a support rod 03, a movable rod 04 and a driving mechanism 05.

[0020] like Figure 1 , Figure 2 As shown, the workbench 01 is arranged horizontally, and the spray rod 02 includes a rubber tube 021 and a pair of steel tubes 022. The pair of steel tubes 022 are arranged at both ends of the rubber tube 021. Nozzles 023 are arranged on the rubber tube 021 and the steel tube 022. An injection tube 024 is connected to the middle position of the rubber tube 021.

[0021] like Figure 1 , Figure 2 , Figure 3 As shown, a screw rod 025 is horizontally rotatably connected inside the steel pipe 022, a partition plate 026 is threadedly connected to the screw rod 025, and the partition plate 026 is horizontally slidably connected to the steel pipe 022 to realize the free on-off switching of the vertical beam of the nozzle 023.

[0022] like Figure 1 , Figure 2As shown, the support rod 03 is vertically arranged on the workbench 01, and the upper end is fixed to the middle position of the rubber tube 021. The movable rod 04 is vertically arranged on the workbench 01, and is distributed on both sides of the support rod 03. The upper end of the movable rod 04 is fixed to the middle position of the steel tube 022, and the lower end is provided with an arc-shaped slider 041, and the workbench 01 is provided with an arc-shaped slide groove 042 for the slider 041 to slide.

[0023] like Figure 1 , Figure 2 As shown, the driving mechanism 05 is used to control the synchronous sliding of a pair of sliders 041 , and the driving mechanism 05 includes a shaft 051 , a driving rod 052 , a gear 053 , a rack 054 and a locking rod 055 .

[0024] like Figure 1 , Figure 2 As shown, the shaft rod 051 is vertically arranged on the workbench 01 and distributed on both sides of the support rod 03. The driving rod 052 is rotatably connected to the shaft rod 051 and fixed to the inner wall of the slider 041. At the same time, the gear 053 is arranged at the end position of the driving rod 052.

[0025] like Figure 1 , Figure 2 As shown, the rack 054 is slidably connected to the workbench 01 in a transverse direction and meshes with the gear 053. The locking rod 055 vertically penetrates the rack 054, and the workbench 01 is provided with a row of locking holes 056 for the locking rod 055 to be inserted.

[0026] When it is necessary to spray paint the corners of the wall, first pull the locking rod 055 out of the locking hole 056, and then control the rack 054 to slide horizontally. At this time, under the cooperation of the rack 054 and the gear 053, the driving rod 052 will be controlled to rotate.

[0027] Then the driving rod 052 drives the slider 041 to slide in the slide groove 042, and the slider 041 drives the movable rod 04 to move synchronously. At this time, the movable rod 04 drives the steel pipe 022 to move synchronously and drives the rubber tube 021 to bend, thereby adjusting the angle between a pair of steel pipes 022 to adapt to different angles of yin and yang angles.

[0028] When the angle between a pair of steel pipes 022 meets the use requirements, the locking rod 055 is vertically inserted into the corresponding locking hole 056 to complete the fixation of the rack 054, thereby achieving the fixation of the steel pipe 022 to complete the angle adjustment of the entire spray rod 02.

[0029] Finally, the latex paint is passed into the injection pipe 024, and the latex paint is sprayed out along the nozzles 023 on the steel pipe 022 and the rubber pipe 021 to realize the painting operation on the wall.

[0030] When it is necessary to spray paint a large flat wall, the spray bar 02 can be adjusted to a straight line to meet the large-area spray painting needs.

[0031] Before painting, the screw 025 can be controlled to rotate, and the screw 025 drives the partition 026 to slide synchronously. The sliding position of the partition 026 determines how many nozzles 023 are opened and closed, so as to adapt to the spraying requirements of painting positions of different widths and improve the practicality of the entire spraying structure.

[0032] Therefore, by setting the spray rod 02 with adjustable angle, the spray rod 02 can be adjusted to a straight line to realize the spraying operation of a large area of ​​wall and improve the construction efficiency. The spray rod 02 can also be adjusted to a right angle inward or outward to adapt to the inner corner or outer corner position, thereby ensuring that the paint thickness at the inner and outer corner positions is consistent, avoiding over-spraying or missed spraying, and improving the construction quality. Example

[0033] like Figure 4 , Figure 5 As shown, a spraying robot for spraying latex paint on a wall includes a walking vehicle 1, a mechanical arm 2, a protection box 4, a batching box 5, a slurry box 6 and a water tank 7.

[0034] like Figure 4 , Figure 5 As shown, the walking trolley 1 is used to walk on the ground, so that the walking trolley 1 moves to the position where the paint needs to be sprayed. The mechanical arm 2 is set on the walking trolley 1 and is fixed to the workbench 01, so as to use the mechanical arm 2 to control the position of the workbench 01 to realize the wall painting operation.

[0035] like Figure 4 , Figure 5 , Figure 6 As shown, the protection box 4 is hollow and arranged on the walking trolley 1, and the batching box 5 is arranged inside the protection box 4, and includes a finished product box 51 and a mixing box 52. The lower end of the finished product box 51 is connected to the injection pipe 024, and the mixing box 52 is arranged above the finished product box 51, and a mixing paddle 8 is arranged inside. The lower end of the mixing box 52 is provided with a discharge port 56, and the discharge port 56 is horizontally slidably connected to a switch plate 57.

[0036] like Figure 5 , Figure 6 , Figure 7 As shown, the slurry box 6 is disposed above one end of the stirring box 52 and is connected to the stirring box 52 . The slurry box 6 includes a slurry hopper 61 , a connecting pipe 62 , a discharge pipe 63 and a rotating shaft 64 .

[0037] like Figure 5 , Figure 6 , Figure 7As shown, the slurry hopper 61 is vertically arranged, the connecting pipe 62 is horizontally connected and arranged below the slurry hopper 61, and the discharge pipe 63 is connected to the connecting pipe 62 and the mixing box 52. The rotating shaft 64 is horizontally rotatably connected in the connecting pipe 62, and the rotating shaft 64 is provided with a trough 65 for connecting the slurry hopper 61 and the discharge pipe 63.

[0038] like Figure 5 , Figure 6 , Figure 7 As shown, a reamer 66 is horizontally rotatably connected in the slurry hopper 61 , and a pulley set 67 that cooperates with each other is provided between the rotating shaft 64 and the reamer 66 .

[0039] like Figure 5 , Figure 6 , Figure 7 As shown, the water tank 7 is arranged above the other end of the mixing tank 52 and connected to the mixing tank 52. The water tank 7 includes a water bucket 71, a water outlet pipe 72 and a rotary valve 73. The water bucket 71 is arranged vertically, the water outlet pipe 72 vertically connects the water bucket 71 and the mixing tank 52, and the rotary valve 73 is arranged on the water outlet pipe 72.

[0040] like Figure 5 , Figure 6 , Figure 7 As shown, a first ratchet wheel 74 and a first ratchet ring 75 are provided at the end of the rotary valve 73 . The first ratchet ring 75 is rotatably connected to the outer side of the first ratchet wheel 74 , and a first sprocket set 76 that cooperates with the rotating shaft 64 is provided between the first ratchet ring 75 and the rotating shaft 64 .

[0041] like Figure 5 , Figure 6 , Figure 7 As shown, the end of the rotary valve 73 is provided with a second ratchet 77 and a second ratchet ring 78, the directions of the second ratchet 77 and the second ratchet ring 78 are opposite to the directions of the first ratchet 74 and the first ratchet ring 75, and the second ratchet ring 78 is rotatably connected to the outer side of the second ratchet 77. The outer wall of the water bucket 71 is provided with a motor 711, and a second sprocket set 79 that cooperates with each other is provided between the second ratchet ring 78 and the motor 711.

[0042] When the wall needs to be painted, the slurry and clean water are respectively put into the slurry box 6 and the water tank 7. At this time, the reducer is used to control the intermittent rotation of the rotating shaft 64. When the material trough 65 on the rotating shaft 64 rotates to the upper end, the material trough 65 is connected to the slurry hopper 61, and the slurry enters the material trough 65. When the material trough 65 rotates to the lower end, the material trough 65 is connected to the discharge pipe 63, and the slurry is quantitatively put into the mixing box 52.

[0043] When the rotating shaft 64 rotates, under the cooperation of the pulley group 67, it will drive the reamer 66 in the slurry box 6 to rotate synchronously, so as to achieve the stirring of the slurry, break the action between the slurry, prevent the arching phenomenon, and enable the slurry to stably enter the material tank 65.

[0044] When the rotating shaft 64 rotates, the first ratchet ring 75 is driven to rotate under the cooperation of the first sprocket set 76. At this time, the first ratchet ring 75 and the first ratchet wheel 74 can interact with each other, so that the first ratchet wheel 74 rotates synchronously with the first ratchet ring 75, and drives the rotary valve 73 to rotate, so as to realize the continuous opening and closing control of the water outlet pipe 72, so that the clean water is quantitatively put into the mixing box 52. When the rotating shaft 64 drives the rotary valve 73 to rotate, the second ratchet wheel 77 and the second ratchet ring 78 will not act relative to each other, and will idle, so as not to affect the motor 711.

[0045] After the slurry and clean water are put into the mixing box 52, the stirring paddle 8 can be used to fully stir the raw materials to achieve full mixing of the raw materials. When the raw materials are prepared, the switch plate 57 is opened, the paint enters the finished product box 51, and can be transported to the injection pipe 024 for painting. At this time, under the action of the walking trolley 1 and the mechanical arm 2, the wall is sprayed and the automatic spraying of the paint is completed.

[0046] Therefore, by providing a batching box 5 that can prepare latex paint at all times, continuous preparation and supply of latex paint can be achieved to meet the spraying demand without stopping the machine for replenishing the latex paint. At the same time, the latex paint can be prepared as needed, thereby reducing the waste of latex paint.

[0047] When spraying operation is not required, the motor 711 is controlled to work. At this time, under the cooperation of the second sprocket set 79, the second ratchet ring 78 is driven to rotate. At this time, the second ratchet ring 78 and the second ratchet wheel 77 can rotate synchronously, and the first ratchet wheel 74 and the first ratchet ring 75 are idle.

[0048] Then the second ratchet 77 drives the rotary valve 73 to rotate, thereby opening the water tank 7, allowing clean water to pass through the positions where the paint passes in sequence, so that the clean water can rinse all working parts, ensuring the cleanliness of the working parts and avoiding blockage caused by solidification of latex paint.

[0049] Therefore, by arranging a rotary valve 73 which can be opened and closed in both directions on the water tank 7, the water in the water tank 7 can be opened and closed following the operation of the slurry box 6 to achieve the preparation of latex paint, and can also be opened and closed independently so that clean water can be used to rinse all working parts, thereby ensuring the cleanliness of the working parts and avoiding blockage caused by solidification of the latex paint.

[0050] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, such modifications are protected by the patent law as long as they are within the scope of the claims of the present invention.
