A guiding groove adapted to the rotating rollers 6 is provided on the guiding plate 7. When the rotating rollers 6 move along the guiding groove, the lifting template 3 synchronously rises and falls with the support columns 4. The guiding groove sequentially includes a spraying area, a lifting area, and a transfer area from front to back. The height of the spraying area is lower than the height of the transfer area, and the height of the transfer area is lower than the height of the lifting area. The front and rear sides of the lifting area are respectively connected to the spraying area and the transfer area through inclined surfaces for transition connection; In this embodiment, legs are provided at the four corners below the spraying table 1. Initially, the moving member drives the loading plate 2 to be at the frontmost side of the spraying table 1. At this time, the rotating rollers 6 are in the spraying area, and the top wall of the lifting template 3 is lower than the top wall of the loading plate 2. The lifting template 3 is connected to the support plate 5 with the rotating rollers 6 through the support columns 4. Workers place the soles on the molding cavities on the left and right sides of the loading plate 2. A spraying component for spraying the soles in the molding cavities is provided on the spraying table 1. When the loading plate 2 moves to below the output end of the spraying component, the rotating rollers 6 are still in the spraying area, and the spraying component sprays the soles. Then the loading plate 2 continues to feed backward towards the rear side of the spraying table 1. A transfer component is further provided at the rear side of the spraying table 1. The transfer component includes a transfer belt 8 and a driving member. A driving member for driving the transfer belt 8 to move is provided at the rear side of the spraying table 1. A blanking groove 9 with a groove depth greater than the thickness of the lifting template 3 is provided on the transfer belt 8. When the rotating rollers 6 are in the lifting area, the bottom wall of the lifting template 3 is higher than the top wall of the transfer belt 8. When the rotating rollers 6 are in the transfer area, the top wall of the lifting template 3 is lower than the top wall of the transfer belt 8. When the rotating rollers 6 move to the lifting area, at this time the soles are in front of the transfer belt 8 and above the transfer belt 8. As the rotating rollers 6 enter the transfer area, at this time the lifting template 3 extends into the blanking groove 9, and the lower part of the soles contacts the transfer belt 8. Start the driving member, and the driving member drives the transfer belt 8 to move; In this embodiment, the spraying assembly includes side plates 10, a top plate 11, a first lifter 12, a first lifting plate 13, a spray head 14 and a liquid supply assembly. The side plates 10 are symmetrically arranged on the left and right sides of the spraying table 1. The top plate 11 is further arranged on the two groups of side plates 10. The output end of the first lifter 12 penetrates through the top plate 11 and is connected to the first lifting plate 13. Spray heads 14 adapted to the corresponding mold cavities are arranged on the left and right sides below the first lifting plate 13. A liquid supply assembly with an output end connected to the spray head 14 is further arranged on the top plate 11. The spraying table 1 provides stable support for the two groups of side plates 10, and the two groups of side plates 10 provide stable support for the top plate 11. When the rear end of the sole is moved below the spray head 14, the height of the first lifting plate 13 can be adjusted by the first lifter 12, and then the height of the spray head 14 can be adjusted. According to requirements, the output area of the spray head 14 can be selected to ensure comprehensive painting treatment of the sole while avoiding waste. The liquid supply assembly includes a liquid supply tank 15, a liquid supply pump 16 and a connecting pipe 17. The liquid supply tank 15 is arranged on the top plate 11.

The liquid supply pump 16 transports the paint in the liquid supply tank 15 to the spray head 14, and the spray head 14 starts to spray the sole. During the spraying process, the spray head 14 can move according to a preset program or actual requirements to ensure that all parts of the sole are evenly sprayed. After spraying is completed, the first lifter 12 drives the spray head 14 to rise and reset.

[0019] During actual use, the driving member includes a driving frame 18, a first motor 19, driving rollers 20 and brackets 21. Brackets 21 are arranged on the left and right sides below the driving frame 18. The bearing plate 2 is arranged between the two sets of brackets 21. A number of driving rollers 20 are arranged on the driving frame 18. The transfer belt 8 is sleeved on a number of driving rollers 20. The output end of the first motor 19 penetrates through the driving frame 18 and is connected to a driving roller 20. The bottom wall of the driving frame 18 is higher than the top wall of the bearing plate 2. The sole part of the mold cavity is arranged at one end close to the transfer assembly. The two support columns 4 are arranged at the heel part of the mold cavity. A storage groove for storing the starting template 3 is further arranged on the bottom wall of the mold cavity. The left and right widths of the starting template 3 are narrower than the left and right widths of the shoe sole. The area of the sole part at the rear side of the mold cavity is larger, and its contact area with the transfer belt 8 is larger. Here, it should be noted that the side wall of the storage groove is slightly larger than the starting template 3, and the area of the starting template 3 is larger than two-thirds of the area of the shoe sole, which can stably support the shoe sole. The shoe sole is made of a light material, and the starting template 3 supported by the support rod can stably support the shoe sole without deformation. When the rotating roller 6 moves to the transfer area, the lifted shoe sole descends at this time, the shoe sole contacts the transfer belt 8, and the starting template 3 is located in the blanking groove 9. There will be no movement interference among the starting template 3, the transfer belt 8, the driving frame 18 and the bearing plate 2. The spraying table 1 provides stable support for the two sets of brackets 21, and the two sets of brackets 21 stably support the driving frame 18. Start the first motor 19, and the first motor 19 drives the driving roller 20 to rotate. Then, the transfer belt 8 supported by a number of driving rollers 20 drives the shoe sole for transportation. During the transportation process, a drying device can be used to dry the shoe sole, and this process does not affect the transportation of materials and the subsequent spraying operation of materials; After the material transfer is completed, the moving member drives the bearing plate 2 to reset and waits for the next feeding, spraying and transfer operations.

[0020] In this embodiment, a roller sleeve 22 is further arranged on the rotating roller 6. The upper and lower sides of the roller sleeve 22 are attached to the upper and lower sides of the guide groove. The rotating rollers 6 are arranged on both the left and right sides of the support plate 5. The roller sleeve 22 cooperates with the rotating roller 6 to stably fit with the guide groove. The two guide plates 7 cooperate with the two rotating rollers 6 to stably ensure the lifting and lowering of the support plate 5.

[0021] In this embodiment, the moving member includes a second motor 23, a lead screw 24, a moving seat 25, a mounting seat 26 and a guide rail 27. The mounting seats 26 are symmetrically arranged on the front and rear sides of the spraying station 1. The lead screw 24 is rotatably arranged between the two groups of mounting seats 26. The mounting seat 26 located at the rear side is also provided with a second motor 23 connected to the lead screw 24. The moving seat 25 is provided with a screw hole adapted to the lead screw 24. The spraying station 1 is also provided with two groups of guide rails 27. The lower part of the moving seat 25 is slidably connected to the guide rail 27. The moving seat 25 is arranged between the two groups of adjustment members. After the second motor 23 is started, the lead screw 24 is driven to rotate. The lead screw 24 is matched with the screw hole on the moving seat 25. Since the lower part of the moving seat 25 is slidably connected to the guide rail 27, the moving seat 25 moves smoothly forward and backward along the guide rail 27 under the rotation of the lead screw 24. The moving seat 25 is arranged between the two groups of adjustment members, thereby driving the bearing plate 2 to move synchronously. The rotating roller 6 of the adjusting member is located in the guide groove of the guide plate 7. When the bearing plate 2 moves, the rotating roller 6 moves in the guide groove accordingly. The guide groove is divided into a spraying area, a lifting area and a transfer area, and the heights are different. The lifting area is the highest, the transfer area is the second, and the spraying area is the lowest. Each area is connected by an inclined transition. In the spraying area, the template 3 is in a lower position. At this time, the template 3 is located in the mold cavity, which is convenient for the placement of the sole and subsequent spraying operations. When the rotating roller 6 moves to the lifting area, due to the increase in the height of the guide groove, the support column 4 rises synchronously with the rotating roller 6, and then drives the template 3 to rise, so that the bottom wall of the template 3 is higher than the top wall of the transfer belt 8, which is convenient for the subsequent transfer of the sole. When the rotating roller 6 enters the transfer area, the height of the guide groove decreases, and the template 3 decreases accordingly. The top wall of the template 3 is lower than the top wall of the transfer belt 8, which is convenient for the sole to be placed smoothly on the transfer belt 8.

[0022] In actual use, the staff places the sole in the mold cavity on the left and right sides of the load-bearing plate 2, places the sole part close to one end of the transfer assembly, and aligns the heel part with the support column 4. Then, the second lifter 28 is started, driving the second lift plate 29 to descend, so that the pressing frame 30 fits the edge of the mold cavity, applies a certain pressure to fix the sole, and confirms that the sole is accurately positioned through the hollow hole in the center of the pressing frame 30; It should be noted here that the first lifter 12 and the second lifter 28 use cylinders, and the first motor 19 and the second motor 23 use servo motors with high control accuracy and fast response. Due to the presence of the downward pressure component, the template 3 can be at the lowest end at the loading position due to the action of gravity and the pressure of the downward pressure component, and then the rotating roller 6 cooperates with the bottom wall of the guide groove to complete the stable operation of lifting and transferring the sole, and the adjustment parts will not get stuck.

[0023] During actual use, the first lifting plate 13 is provided with a first guide rod 31 penetrating through the top plate 11, and the second lifting plate 29 is provided with a second guide rod 32 penetrating through the top plate 11. The first guide rod 31 ensures the stability of the lifting of the first lifting plate 13, and the second guide rod 32 ensures the stability of the lifting of the second lifting plate 29.
