[0038] The dust removal assembly 5 includes an inner plate 5-1, which is located inside the rear frame 2. Several fans 5-2 are installed in the inner plate 5-1. A pair of sliding grooves 5-3 are opened on the inner plate 5-1, and filter plates 5-4 are inserted into the sliding grooves 5-3. A pair of lower pressure rollers 5-5 are rotatably connected inside the rear frame 2. A pair of support rollers 5-6 are rotatably connected inside the rear frame 2. A pair of horizontal pipes 5-7 are installed inside the rear frame 2. A suction fan 5-8 is installed on the outer surface of the rear frame 2.

The support rollers 5-6 are located on both sides of the horizontal pipes 5-7, and the upper surface of the lower support roller 5-6 is higher than the surface of the bottom horizontal pipe 5-7.
[0039] In this embodiment, a dust removal component 5 is designed to achieve the effect of dust removal and pre-cooling of the leather surface. An inner plate 5-1 is set inside the rear frame 2 and multiple fans 5-2 are installed. The fans 5-2 can blow air onto the leather surface being conveyed on the conveyor belt 3. Two grooves 5-3 are opened at the top of the inner plate 5-1, and filter plates 5-4 are inserted in the grooves 5-3 to filter the air blown by the fans 5-2. Two support rollers 5-6 and two pressure rollers 5-5 are rotatably connected inside, which can support the leather on the surface of the conveyor belt 3 to a certain height. Two horizontal pipes 5-7 are set inside the rear frame 2. The horizontal pipes 5-7 are located between the support rollers 5-6, and dust suction holes 5-9 are opened on the surface of the horizontal pipes 5-7. A suction fan 5-8 is set on the outside of the rear frame 2, which can generate a large suction force from the dust suction holes 5-9 to absorb the leather surface and floating dust, thereby achieving the dust removal effect.
[0040] Furthermore, the cooling treatment component 6 includes a pair of circulation pipes 6-1, both of which are located at the inlet and outlet ends of the cold water circulator 4. Both sides of the rear frame 2 are provided with centralized pipes 6-2, and both sides of the rear frame 2 are provided with several connecting pipes 6-3. The connecting pipes 6-3 are all connected to the centralized pipes 6-2.

It can fit against the surface of the leather and rotate with the leather conveyor belt 3.
[0042] Furthermore, the inner panel 5-1 has a certain tilt angle, and the fan 5-2 faces the inside of the rear frame 2.
[0043] In this embodiment, by tilting the fan 5-2 to blow into the interior of the rear frame 2, a certain amount of airflow can be generated inside the rear frame 2 to achieve the effect of removing dust from the leather surface.
[0044] Furthermore, the rotating pipes 6-4 are all made of materials that can conduct heat.
[0045] In this embodiment, the rotating pipe 6-4 is kept at a low temperature to the maximum extent by means of a material structure that can conduct heat, so as to fully cool the leather.

[0047] In this embodiment, the sealing layer 7 is provided to enhance the sealing effect between the sealing layer and the rotating pipe 6-4, thereby preventing water leakage during rotation.
[0048] Furthermore, the rear frame 2 is equipped with an inner cover 8, which has an overall horizontal L-shaped structure.
[0049] In this embodiment, an inner cover 8 is provided to enclose the entire structure inside, thus preventing secondary pollution.
[0050] When processing is required, the leather enters the printing machine body 1 for processing and is then conveyed outward via the conveyor belt 3. During the process, the fan 5-2 is activated to blow air onto the leather surface for initial cooling and removal of surface dust. At the same time, the suction fan 5-8 is activated to draw dust from the leather surface through the suction holes 5-9 for further dust removal. The cold water circulator 4 continuously circulates cooling water, which flows through the central pipe 6-2, connecting pipe 6-3, and rotating pipe 6-4, keeping the rotating pipe 6-4 at a low temperature and rotating with the leather conveyor. After cooling, the leather is rolled up.
[0051] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
