Description

Technical Field

[0001] This utility model relates to the field of adjustment structure technology, specifically a multi-angle adjustment structure for a leather spraying machine. Background Technology

[0002] A leather spraying machine is a specialized piece of equipment for leather surface treatment. It uses a spray gun or nozzle to evenly spray paint, dye, or other treatment agents onto the leather surface to achieve functions such as coloring, coating, texture treatment, or waterproofing. This equipment can improve the efficiency and quality of leather processing, ensure the uniformity and consistency of the coating, and is widely used in leather manufacturing, footwear, clothing, furniture, and other industries. When applying coatings to leather, the inconsistent cross-sectional areas of different batches of leather mean that if the spray angle of the nozzle is not flexibly adjusted according to the specific cross-sectional area of ​​the leather, the utilization rate of the treatment agent will be reduced, and the overall quality of the coating will be affected, ultimately leading to a decline in product quality. Therefore, a multi-angle adjustment structure for a leather coating machine is proposed to address the above problems. Utility Model Content

A sleeve block 67 is fixedly connected to the right end of the movable cylinder 65. A limiting groove 69 is opened at the upper end of the sleeve block 67, and the sleeve block 67 is sleeved on the outer side of the rail ring 55 through the limiting groove 69.

[0017] As a further implementation of this solution, an angle control component 3 is fixedly connected to the top of the support frame 2. The conveying mechanism 1 is located at the lower end of the angle control component 3. The angle control component 3 includes a top plate 31, a cross frame 32 is fixedly connected to the top of the top plate 31, the top of the cross frame 32 is fixedly connected to the housing of the servo motor 33, a first gear 34 is fixedly connected to the end of the main shaft of the servo motor 33, a ball bearing 35 is fixedly connected to the inner side of the cross frame 32, and the outer side of the first gear 34 meshes with the second gear 63. Through the above settings, the stability and reliability of the spraying process are ensured, the spraying angle is flexibly adjusted, the efficiency of power transmission is improved, and the accuracy and stability of the spraying angle adjustment are also ensured, further improving the spraying quality. As a further implementation of this solution, the top of the rail plate 51 and the top of the servo cylinder 53 are both fixedly connected to the bottom of the top plate 31, and the top of the built-in plate 52 and the top of the steel ring 54 are both clearance-fitted to the bottom of the top plate 31. With the above settings, the device can flexibly adjust the shape of the steel ring 54 and the rail ring 55 according to the cross-sectional area of ​​the leather, thereby changing the spraying angle. This design not only improves the adaptability and flexibility of the device, but also reduces the problem of uneven spraying caused by changes in leather size, and significantly improves the spraying quality. As a further implementation of this solution, a first rubber sealing ring 62 is fixedly connected to the upper end of the shaft 61, and a second gear 63 is fixedly connected to the lower end of the shaft 61. The shaft 61 is rotatably connected to the cross frame 32 via a ball bearing 35. The outer side of the second gear 63 meshes with the outer side of the first gear 34. A channel is opened on the inner side of the shaft 61, and a through hole is opened at the left end of the cylindrical shell 64. The inner side of the movable cylinder 65 is a hollow structure. The outer side of the shaft 61 is inserted into the inside of the connecting pipe 4. The first rubber sealing ring 62 is fixedly connected to the upper end of the shaft 61. 2. The outer side is fitted to the inner side of the connecting pipe 4. The bottom end of the sleeve block 67 is fixedly connected to the nozzle 68. The inner side of the shaft column 61, the inner side of the cylinder shell 64, the inner side of the movable cylinder 65, the inner side of the sleeve block 67 and the inner side of the nozzle 68 are connected. Through the above settings, the shaft column 61 can rotate flexibly as needed, thereby driving the nozzle 68 to change the spraying angle. This ensures that the treatment agent can be smoothly delivered from the spraying machine to the nozzle 68, which not only improves the uniformity of spraying, but also reduces the waste of treatment agent, and further improves the spraying quality and product quality.

[0018] Workflow: When spraying leather, the leather is placed on the upper end of the conveyor mechanism 1 and conveyed by the conveyor mechanism 1. The connecting pipe 4 is fixed to the output pipe of the spraying machine. The spraying machine delivers the treatment agent into the interior of the connecting pipe 4. The treatment agent passes through the connecting pipe 4 into the shaft column 61, cylinder shell 64, movable cylinder 65, sleeve block 67, and nozzle 68. The nozzle 68 sprays the treatment agent onto the leather. At the same time, the servo motor 33 is started. The servo motor 33 drives the first gear 34 to rotate, and the first gear 34 drives the meshing second gear 63 to rotate. Gear 63 drives the entire spraying assembly 6 to rotate. The shaft 61 is rotatably connected to the inside of the cross frame 32 through ball bearing 35. Since the limiting groove 69 is sleeved on the outside of the steel ring 54, and the limiting groove 69 and the steel ring 54 have a certain gap, it prevents the sleeve block 67 from getting stuck with the steel ring 54 after the steel ring 54 is adjusted and deformed. The sleeve block 67 slides on the outside of the rail ring 55 through the limiting groove 69, and slides along the changing trajectory of the rail ring 55. At the same time, the movable cylinder 65 will slide inside the cylinder shell 64 in the movable chamber of the sleeve block 67, thereby achieving the effect of spraying leather. When adjusting the spraying angle based on the cross-sectional area of ​​the leather, if the left-right span of the leather is large, two servo electric cylinders 53 are activated, causing their respective built-in plates 52 to move. The built-in plates 52 slide inside the rail plate 51, causing the steel ring 54 and the rail ring 55 to deform left and right. This narrows the distance between the front and back of the steel ring 54 and the rail ring 55. At this point, it is necessary to control the conveying speed of the conveying mechanism 1. By changing the shape of the steel ring 54, the movement trajectory of the nozzle 68 is controlled; thus, the effect of adjusting the spraying angle of the leather based on its cross-sectional area is achieved. Based on the above principles, the device now adjusts the spraying angle of the leather according to its cross-sectional area. This spraying method can adapt well to various leather sizes, reduce the limitations of the spraying angle, reduce the waste of sprayed treatment agent, and improve the overall quality and grade of leather spraying.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
