DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0029] Example 1: An industrial railing spraying device, see Figures 1 to 6 , including a spraying frame 1, the front end of the spraying frame 1 is provided with four groups of equally spaced push grooves 11, each group of push grooves 11 is arc-shaped, and a positioning and rotating mechanism is installed in each group of push grooves 11. By inserting multiple groups of railings into the push grooves 11 in sequence, and cooperating with the positioning and rotating mechanism installed in each group of push grooves 11, not only can each group of railings be fixed, but also the railings can be driven to rotate. The positioning and rotating mechanism includes a positioning cylinder 2 rotatably installed at one end of each group of push grooves 11, a bidirectional screw 21 is rotatably installed in each group of positioning cylinders 2, a first threaded cylinder 22 and a second threaded cylinder 23 are rotatably installed at both ends of each group of bidirectional screws, three groups of equally spaced first push rods 24 and second push rods 25 are rotatably installed on the side walls of each group of first threaded cylinders 22 and second threaded cylinders 23, a push block 26 is rotatably installed at the other end of two adjacent groups of first push rods 24 and second push rods 25, a drive box 5 fixedly installed on one side of the spraying frame 1, and a self-rotating mechanism is installed inside the drive box 5;

[0030] A limited slide groove 12 is provided at the bottom of the front end of the spray rack 1, and a slider 13 is slidably installed in the limited slide groove 12. A spray cover 14 is fixedly installed on the side wall of the slider 13, and a positioning spraying mechanism is installed on the spray cover 14. When multiple groups of railings are installed on the spray rack 1 in sequence, the spray cover 14 is driven to align the spray cover 14 with the spray rack 1, and multiple groups of railings on the spray rack 1 are automatically sprayed to avoid manual spraying with a spray gun, which causes the operator to absorb a large amount of harmful substances and affect his health. The positioning spraying mechanism includes a screw 3 rotatably installed in the limited slide groove 12, an inner groove 31 provided on the inner side of the spray cover 14, four groups of equidistantly distributed nozzles 32 are fixedly installed in the inner groove 31, multiple groups of equidistantly distributed nozzles 33 are connected and installed on each group of nozzles 32, and a guide pipe 34 connected and installed with the four groups of nozzles 32, the screw 3 is threadedly connected to the slider 13, and the screw 3 passes through the limited slide groove 12 and is fixedly connected to the motor shaft of the third motor.

[0031] Working principle: the operator first inserts multiple groups of railings into the push groove 11 in sequence, and slowly pushes the multiple groups of railings so that one end of each group of railings is plugged into multiple groups of positioning cylinders 2, and then drives the first motor 42, cooperates with the two adjacent groups of connecting shafts 4 to be connected through the transmission belt 41, so that the bidirectional screw rod 21 fixedly connected at one end of each group of connecting shafts 4 can be rotated synchronously. Since the first threaded cylinder 22 and the second threaded cylinder 23 are respectively threadedly installed at both ends of each group of bidirectional screw rods 21, it is ensured that when the bidirectional screw rod 21 rotates, the first threaded cylinder 22 and the second threaded cylinder 23 can push the first push rod 24 and the second push rod 25 to move inward and outward synchronously, so that the push blocks 26 rotatably installed at the other ends of the adjacent two groups of first push rods 24 and second push rods 25 are firmly attached to the inner wall of the railing, and the multiple groups of railings are positioned inside the push groove 11, and the drive The third motor drives the screw rod 3 to rotate, so that the slider 13 moves horizontally along the limiting slide groove 12, and the spray hood 14 is aligned with the spray frame 1. The pump installed inside the driving paint box 44 makes the multiple nozzles 33 on the four groups of nozzles 32 spray paint evenly and spray the surface of the railing inside each group of push grooves 11. As the spray hood 14 continues to work, the second motor 53 installed on the side wall of the driving box 5 is turned on to drive the second gear 52 to rotate. Since the two adjacent groups of first gears 51 are meshed with the second gear 52, the positioning cylinders 2 installed inside the four groups of first gears 51 can be driven to rotate, so that the railings installed inside the four groups of push grooves 11 rotate, so that the sprayed paint is evenly distributed on the surface of the railing, and it is avoided that the operator absorbs a large amount of harmful substances and affects his health by holding the spray gun manually.

[0032] For details, see Figure 1-6, the inner walls of the four groups of push grooves 11 are provided with multiple groups of equidistantly distributed collecting holes 54, and the adjacent groups of collecting holes 54 are connected and installed with collecting pipes 55, and the four groups of collecting pipes 55 are installed inside the spray rack 1, and the other ends of the four groups of collecting pipes 55 are connected and installed with connecting pipes 56, and the other end of the connecting pipe 56 is connected and installed with the negative pressure end of the negative pressure pump. When the multiple groups of nozzles 32 inside the spray hood 14 spray the railings, a large amount of paint will remain on the inner wall of each group of push grooves 11. At the same time, the connecting pipe 56 is driven to connect with an external negative pressure pump to deliver negative pressure to the multiple groups of collecting pipes 55, so that a strong negative pressure is generated in each group of collecting holes 54, so that the paint retained on the inner wall of the push groove 11 can be effectively collected and recycled, thereby avoiding a large amount of paint waste.

[0033] For further information, see Figure 1-6 A support plate 43 is fixedly installed at one end of the bottom of the side wall of the spray hood 14, and a paint box 44 is fixedly installed on the top of the support plate 43. A suction pump is fixedly installed inside the paint box 44, and the discharge end of the suction pipe is connected and installed with the other end of the guide pipe 34. Three groups of equidistantly distributed support wheels 45 are detachably installed at the bottom of the spray hood 14, and the bottom sides of the three groups of support wheels 45 are all in contact with the ground. By driving the suction pump installed inside the paint box 44, the multiple groups of nozzles 33 on the four groups of nozzles 32 can evenly spray paint and spray the surface of the railing inside each group of push grooves 11. When the spray hood 14 moves horizontally, the support force installed at the bottom of the spray hood 14 can support the bottom of the spray hood 14.

[0034] Further, see Figure 1-6 , four groups of bidirectional screw rods 21 all penetrate the side wall of the positioning cylinder 2 and are fixedly installed with a connecting shaft 4, and two adjacent groups of connecting shafts 4 are connected by transmission belts 41, and one end of the top connecting shaft 4 is fixedly installed with the motor shaft of the first motor 42, and the first motor 42 is fixedly installed on the top of the side wall of the spray rack 1. By driving the first motor 42, and cooperating with the two adjacent groups of connecting shafts 4 to be connected by transmission belts 41, the bidirectional screw rods 21 fixedly connected at one end of each group of connecting shafts 4 can be made to rotate synchronously. Since the first threaded cylinder 22 and the second threaded cylinder 23 are respectively threadedly installed at both ends of each group of bidirectional screw rods 21, it is ensured that when the bidirectional screw rod 21 rotates, the first threaded cylinder 22 and the second threaded cylinder 23 can push the first push rod 24 and the second push rod 25 to move inward and outward synchronously, so that the push blocks 26 rotatably installed at the other ends of the two adjacent groups of first push rods 24 and the second push rods 25 are firmly attached to the inner wall of the railing.

[0035] It is worth noting that see Figure 1-6The self-rotation mechanism includes four groups of equally spaced first gears 51 rotatably installed inside the driving box 5, a second gear 52 rotatably installed on the top side of the driving box 5, and a second motor 53 fixedly installed on the top of the outer wall of the driving box 5. Two adjacent groups of first gears 51 are meshed with the second gear 52. The central axes of the four groups of first gears 51 are respectively fixedly connected to the side walls of the four groups of positioning tubes 2. The output end of the second motor 53 is driven to be connected to the transmission shaft, and the other end of the transmission shaft is fixedly installed with the central axis of the second gear 52. The second motor 53 installed on the side wall of the driving box 5 drives the second gear 52 to rotate. Since the two adjacent groups of first gears 51 are meshed with the second gear 52, the positioning tubes 2 installed inside the four groups of first gears 51 can be driven to rotate, so that the railings installed inside the four groups of push grooves 11 rotate, so that the sprayed paint is evenly distributed on the surface of the railing.

[0036] It is worth noting that see Figure 1-6 Each group of positioning cylinder 2 has three groups of equally spaced limiting grooves 27 on its side wall, and each group of limiting grooves 27 is movably connected to the corresponding first push rod 24 and second push rod 25. When the first threaded cylinder 22 and the second threaded cylinder 23 can push the first push rod 24 and the second push rod 25 to move inward and outward synchronously, the limiting grooves 27 and the push rods can effectively limit the first push rod 24 and the second push rod 25, so that the push blocks 26 rotatably installed at the other ends of the two adjacent groups of first push rods 24 and second push rods 25 are firmly attached to the inner wall of the railing.

[0037] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.
