[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The adjustable mechanism allows the equipment to precisely adjust the height and angle of the spray nozzles according to the different thicknesses and sizes of the leather, thereby achieving uniform spraying on the leather surface. When the motor is working, the output shaft of the motor drives the turntable to rotate. The rotation of the turntable drives the first rotating shaft to rotate synchronously. The rotation of the first rotating shaft drives the connecting rod to swing. When the connecting rod swings, it drives the fixed seat to move through the second rotating shaft. When the fixed seat moves, it drives the slider to slide in the slide groove. When the slider slides, it drives the telescopic rod to move. When the telescopic rod extends or retracts, it drives the diverter pipe and the spray nozzle to move up and down, thereby adjusting the height and position of the spray nozzle. At the same time, the swing of the connecting rod can drive the position adjustment of the spray nozzle, thereby achieving uniform spraying on different parts of the leather.

[0016] 2. The fixed mechanism ensures stable clamping of the leather, preventing it from shaking or shifting during spraying and improving the uniformity of dyeing. When the hydraulic cylinder operates, its telescopic end drives the hydraulic rod to extend and retract. This movement of the hydraulic rod moves the movable frame, which in turn moves the slide bar by pulling the cross plate. The slide bar then moves the pressure plate to clamp the leather. The springs provide cushioning to the pressure plate, preventing excessive pressure that could damage the leather. The rubber pads increase friction between the pressure plate and the leather, enhancing clamping stability. Attached Figure Description

The lower end of the support plate 2 is firmly fixed to the upper rear side of the workbench 1, and the lower end of the dyeing box 3 is also fixed to the upper end of the support plate 2. This structural arrangement ensures the stability and reliability of the entire device. Furthermore, one side of the hydraulic cylinder 61 is detachably connected to one side of the side plate 5. The telescopic end of the hydraulic cylinder 61 is provided with a hydraulic rod 62, and one end of the hydraulic rod 62 is provided with a movable frame 63. Both ends of the inner wall of the movable frame 63 are slidably connected with slide rods 64. The upper end of the slide rod 64 is fixedly connected to a horizontal plate 65, and the upper end of the horizontal plate 65 is fixedly connected to a handle 66, which facilitates the movement of the slide rod 64 and the pressure plate 67 by driving the horizontal plate 65 through the handle 66. The slide bar 64 moves upward. A pressure plate 67 is fixedly connected to the lower end of the slide bar 64, and a spring 68 is fixedly connected to the upper end of the pressure plate 67. The spring 68 applies a downward force to the pressure plate 67, so that the lower end of the pressure plate 67 can fit tightly against the leather surface. A rubber pad 69 is glued to the lower end of the pressure plate 67. The rubber pad 69 increases the friction between the lower end of the pressure plate 67 and the leather, preventing the leather from sliding during dyeing. One side of the hydraulic cylinder 61 is fixedly connected to one end of the hydraulic rod 62, and the other end of the hydraulic rod 62 is fixedly connected to one side of the movable frame 63. The spring 68 is sleeved on the outside of the slide bar 64, and the upper end of the spring 68 is fixedly connected to the inner top wall of the movable frame 63.

Through the fixed mechanism 6, the hydraulic cylinder 61 is activated. The hydraulic cylinder 61 drives the hydraulic rod 62 to extend and retract, which in turn moves the movable frame 63. The movable frame 63 then moves the sliding rod 64. Once the desired position is reached, the user stops. Next, pulling the handle 66 moves the horizontal plate 65 upwards, which in turn moves the sliding rod 64. The pressure plate 67 is moved to fix the leather. A spring 68, with its elasticity, compresses the leather. A rubber pad 69 prevents damage to the leather. Then, the adjusting mechanism 4 starts the motor 42, which rotates the turntable 43. The rotation of the turntable 43 rotates the first rotating shaft 44, which in turn moves the connecting rod 45. The moving connecting rod 45 moves the fixed seat 47, which in turn moves the slider 48 within the groove 7. The sliding of the slider 48 causes the telescopic mechanism to extend. The telescopic rod 49 moves, which in turn moves the diverter pipe 410. The diverter pipe 410 then moves the nozzle 411 back and forth, thus enabling uniform spraying of the leather and achieving the goal of uniform dyeing. This solves the problem of uneven spraying results in traditional methods. Furthermore, the telescopic rod 49 at the lower end of the slider 48 can be adjusted according to the different thicknesses of the leather, allowing the diverter pipe 410 to move up or down, increasing the practicality of the device.
