[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example like Figures 1-6 As shown, an automatic spraying machine material transport device includes a housing 1, a spraying mechanism 2, a movement control device 3, a splash paint treatment device 4, and a material transport device. The material transport device passes through the housing 1, the movement control device 3 is installed inside the housing 1 and located on top of the material transport device, and the spraying mechanism 2 is installed on the automatic spraying machine.

[0019] The housing 1 has a horizontal support plate 5 inside. The movement control device 3 includes an X-direction control component 31, a Y-direction control component 32 and a Z-direction control component 33, which respectively control the movement of the spraying mechanism 2 in the X, Y and Z directions. The X-direction control component 31 is set on the top surface of the support plate 5. The Y-direction control component 32 is movably connected to the X-direction control component 31. The Z-direction control component 33 is movably connected to the Y-direction control component 32. The spraying mechanism 2 is movably installed on the Z-direction control component 33.

[0020] like Figure 3As shown, the X-direction control component 31 includes two first guide grooves 311 that are on the same horizontal plane and parallel to each other. The two first guide grooves 311 are fixedly installed on the support plate 5 by support columns 312. Each of the two first guide grooves 311 is equipped with a first motor 313. The output end of the first motor 313 is equipped with a first screw 314. The two ends of the first screw 314 are rotatably installed in the first guide groove 311 by two first bearing seats 316. The first screw 314 is threadedly connected to a first slider 315. The first motor 313 drives the first screw 314 to rotate, thereby driving the first slider 315 to move, and thus driving the Y-direction control component 32 to move in the X direction.

[0021] like Figure 4 As shown, the Y-direction control component 32 includes a second guide groove 321. Two first sliders 315 are respectively installed at both ends of the second guide groove 321. A first motor housing 322 is provided at one end of the second guide groove 321. A second motor 323 is provided inside the first motor housing 322. The output end of the second motor 323 is connected to a first driving pulley 324. The first driving pulley 324 is connected to a first driven pulley 326 through a first transmission belt 325. A second screw 327 is fixedly connected to the first driven pulley 326. The second screw 327 is arranged along the extension direction of the second guide groove 321, and both ends of the second screw 327 are rotatably installed inside the second guide groove 321 through a second bearing seat 328. The second screw 327 is threadedly connected to a second slider 329. The second motor 323 drives the first drive pulley 324 to rotate. Under the transmission of the first transmission belt 325 and the first driven pulley 326, the second screw 327 rotates, thereby driving the second slider 329 to move, and further driving the Z-direction transmission assembly to move in the Y direction.

[0022] like Figure 5As shown, the Z-direction control component 33 includes a third guide groove 331, which is perpendicular to the second guide groove 321 and fixedly connected to the second slider 329. One end of the third guide groove 331 is provided with a second motor housing 332, and a third motor 333 is provided inside the second motor housing 332. The output end of the third motor 333 is connected to a second driving pulley 334. The second driving pulley 334 is connected to a second driven pulley 336 through a second transmission belt 335. A third screw 337 is fixedly connected to the second driven pulley 336. The third screw 337 is arranged along the extension direction of the third guide groove 331, and both ends of the third screw 337 are rotatably installed inside the third guide groove 331 through a third bearing seat 338. The third screw 337 is threadedly connected to a third slider 339, and the spraying mechanism 2 is installed on the third slider 339. The second drive pulley 334 is driven to rotate by the third motor 333. Under the transmission of the second transmission belt 335 and the second driven pulley 336, the third screw 337 is driven to rotate, which in turn drives the third slider 339 to move. This further drives the spraying mechanism 2 to move in the Z direction. Under the combined action of the X direction control component 31, the Y direction control component 32 and the Z direction control component 33, the movement of the spraying mechanism 2 in different directions is satisfied, ensuring the uniformity and integrity of the spraying.

[0023] like Figure 6 As shown, the automatic spraying machine also includes a splatter paint treatment component. The splatter paint control component includes a splatter collection tank 41, which is installed on the top of the material transport device. The splatter collection tank 41 is a square funnel-shaped structure with openings at the top and bottom, which facilitates paint rinsing and allows the paint to flow downwards naturally after rinsing. The inner edge of the bottom opening of the splatter collection tank 41 is provided with an upwardly bent groove 47. The bottom of the groove 47 is connected to at least one drain pipe 48. A wastewater collection tank 42 is provided inside the machine housing 1, and the drain pipe 48 is connected to the wastewater collection tank 42. A water collection trough 44 is provided around the top of the splatter collection tank 41 along the edge of the opening. The inner wall of the water collection trough 44 is provided with multiple water outlets 45. The water collection trough 44 is connected to at least one water inlet pipe 46. A clean water tank 43 is provided inside the machine housing 1, and the water inlet pipe 46 is connected to the clean water tank 43 through a water pump. The water pump delivers clean water to the water collection tank 44. The water in the water collection tank 44 flows through the water outlet 45 on the inner wall to the splash collection tank 41. After the splashed paint splashes onto the inner wall of the splash collection tank 41, it is quickly washed away by the water flow and collected in the bottom groove 47. Then it flows out through the drain pipe 48 to the wastewater collection bucket 42, thereby preventing the splashed paint from drying and adhering, effectively reducing labor and saving production costs.

[0024] like Figures 6 to 10As shown, the material transport device includes a transport trough 6, which includes a base plate 61 and two side plates 62. The two side plates 62 are symmetrically installed on the top surface of the base plate 61 to form a U-shaped transport trough 6. An equipment box 8 located outside the housing 1 is installed on the bottom surface of the base plate 61. A fourth motor 9 is installed inside the equipment box 8. The output shaft of the fourth motor 9 is parallel to the base plate 61 and perpendicular to the extension direction of the base plate 61. A drive gear 12 is installed on the output shaft of the fourth motor 9. The drive gear 12 is meshed with a chain ring 14. The other end of the chain ring 14 passes upward through the base plate 61 and meshes with a driven gear 13. The base plate 61 has a through hole for the chain ring 14 to pass through. A drive shaft 74 is fixedly connected to the driven gear 13. The drive shaft 74 is rotatably installed on the top surface of the base plate 61 through two fourth bearing seats 75. A fourth drive pulley 71 is installed at both ends of the drive shaft 74 after passing through the bearing seats. The fourth motor 9 drives the drive gear 12 to rotate. The drive gear 12 drives the drive shaft 74 to rotate through the chain ring 14 and the driven gear 13, which in turn drives the two fourth drive pulleys 71 to rotate.

[0025] A fifth bearing seat 77 is installed on the top surface of the other end of the base plate 61. Both fifth bearing seats 77 are provided with strip holes 771. A rotating shaft 76 is inserted into each of the two strip holes 771. Both rotating shafts 76 are rotatably connected to a fourth driven pulley 72. The two fourth driven pulleys 72 correspond to two fourth driving pulleys 71 respectively. A conveyor belt 73 is connected between the fourth driving pulley 71 and the corresponding fourth driven pulley 72. The rotation of the two fourth driving pulleys 71 drives the conveyor belt 73 and the fourth driven pulleys 72 to rotate. The plate to be sprayed is placed on the two conveyor belts 73. The plate is transported by the movement of the conveyor belts 73. A fourth screw 772 is perpendicularly inserted through the rotating shaft 76. The axis of the fourth screw 772 is parallel to the extension direction of the transport groove 6. Both ends of the fourth screw 772 are rotatably inserted through the fifth bearing seat 77. A knob 773 is fixedly connected after one end of the fourth screw 772 passes through the fifth bearing seat 77. Rotating the screw by knob 773 moves the shaft 76, thereby adjusting the distance between the drive pulley and the driven pulley, and thus adjusting the tension of the conveyor belt 73 to achieve the best transportation effect.

[0026] The transport trough 6 is movably connected to the booster assembly 10 and the intelligent control assembly 11. The intelligent control assembly 11 includes a third cylinder 111, which is located inside the equipment box 8. The telescopic end of the third cylinder 111 is movably connected to the base plate 61. After the telescopic end of the third cylinder 111 passes through the base plate 61, a first stop block 112 is installed. A first sensor 113 is installed on the top surface of the base plate 61 near the first stop block 112. Since spraying is only one step in the material processing, when the subsequent steps have not been completed, the third cylinder 111 drives the first stop block 112 to rise, blocking the material movement. At this time, the first sensor 113 detects that there is unconveyed material on the conveyor belt 73. Then, the spraying mechanism 2 stops working after spraying the current board, and the fourth motor 9 stops working. It continues working after the unconveyed material is transported.

[0027] The intelligent control component 11 also includes a fourth cylinder 114 near the driven pulley. The fourth cylinder 114 is disposed on the bottom surface of the base plate 61. The telescopic end of the fourth cylinder 114 is movably connected to the base plate 61. After the telescopic end of the fourth cylinder 114 passes through the base plate 61, a second stop 115 is installed. A second sensor 116 is installed on the top surface of the base plate 61 near the second stop 115.

[0028] When the spraying mechanism 2 is spraying material, the second stop 115 rises to block the new material arriving from the previous process. At the same time, the second sensor 116 detects waiting material, so both the material transport devices of the previous and current processes stop transporting. After the spraying in the spraying mechanism 2 is completed, the second stop 115 descends, and the waiting material moves into the housing 1 for spraying. If the second sensor 116 never detects material, the spraying mechanism 2 remains inactive to avoid dry spraying.

[0029] The booster assembly 10 includes a pusher plate 101 near the drive shaft 74. The pusher plate 101 is connected to a drive structure. A rubber pusher block 105 is installed on the bottom surface of the pusher plate 101. The pusher plate 101 is connected to the drive structure, which is movably installed on the side wall of the transport trough 6. A horizontally arranged first cylinder 102 is fixedly installed on the outer side wall of the transport trough 6. A connecting block 103 is fixedly installed on the free end of the first cylinder 102. A second cylinder 104 for vertical equipment is fixedly installed on the connecting block 103. The pusher plate 101 is fixedly connected to the free end of the second cylinder 104. Since the conveying distance of the conveyor belt 73 is limited, when the material leaves the conveyor belt 73 to enter the next process, the contact area between the conveyor belt 73 and the material becomes smaller, making it difficult to convey. Therefore, the push plate 101 is lowered by the second cylinder 104 and pressed against the material surface. The material is moved by the first cylinder 102. The rubber push block 105 installed at the bottom of the push plate 101 helps to increase the pushing friction and improve the pushing effect. At the same time, it can protect the material and avoid damage.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
