Description

A type of suede rubbing machine Technical Field

[0001] This utility model relates to the field of leather processing, and more specifically, to a velvet leather texturing machine. Background Technology

[0002] Texture machines are mainly used to create smooth, simulated textures on the surface of synthetic leather, improving its surface quality. However, existing fully automatic flocked leather texture machines still have some problems. First, during the texture process, external impurities can easily enter the machine through the vents or heat dissipation holes, affecting the texture effect. Furthermore, the internal components can easily generate high temperatures during heating.

[0003] The utility model patent application CN 213835954 U discloses a fully automatic flocked leather texturing machine, comprising a machine body, a mounting plate installed at the bottom of the machine body, and a support column installed at the bottom of the mounting plate. A mounting housing is installed on the top of the machine body, and an exhaust fan is installed inside the mounting housing. The bottom end of the exhaust fan is connected to a blower blade. Heat dissipation vents are provided on both sides of the mounting housing. A drive motor is installed on the left side of the machine body, and a rotating rod is connected to the right end of the drive motor. A texturing cylinder is installed on the right side of the rotating rod, and the outer surface of the texturing cylinder is evenly covered with texturing textures. In this utility model, firstly, a sealed texturing structure is adopted, which not only improves the sealing performance of the flocked leather texturing machine but also improves its heat dissipation and overall performance. Secondly, a modular installation structure is adopted, which not only improves the processing efficiency of the flocked leather texturing machine but also reduces the operating costs of some parts of the machine.

[0004] The aforementioned structure lacks an annular platform on the surface of the kneading drum for separate installation of the arc-shaped plate and insert rod, which is not conducive to cleaning and maintenance, nor to partial replacement. Furthermore, the lack of internal heat-conducting length affects the heating effect and is not conducive to internal heating and cooling by air blowing. It has poor adaptability and needs to be improved. Summary of the Invention

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a flocked leather texturing machine. A guide roller and a texturing cylinder are rotatably mounted on a fixed frame, allowing for the rotatable conveying of leather. Furthermore, by setting up an annular platform and a cavity, combined with the arc-shaped grooves on the surface for inserting arc-shaped plates and rods, it can be installed and positioned separately, increasing the internal heat conduction area and improving heating efficiency. Simultaneously, internal airflow can control heating stability, improving safety and stability. It is suitable for combined use, convenient for separate maintenance, and highly adaptable.

[0012] Furthermore, one end of the right-angle tube is inserted into the interior of the hollow shaft and is located on one side of the outer surface of the movable bracket.

[0013] Furthermore, a gap is left between the right-angle tube and the hollow shaft. The right-angle tube can be inserted into the hollow shaft through the bellows, which facilitates ventilation and air intake, can assist in heating, and can also cool down, improve the safety of kneading, and facilitate adjustment and use.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] (1) This solution has a guide roller and a kneading drum installed by a fixed frame, which can rotate to transport leather for operation. Furthermore, by setting up an annular platform and a cavity, and combining the arc groove on the surface to install an arc plate and a plug rod, it can be installed separately and positioned, which is conducive to increasing the internal heat conduction area and improving heating efficiency. At the same time, it can control the heating stability from the inside, improve safety and stability, facilitate combined use, facilitate separate maintenance, and has high adaptability.

[0016] (2) The hollow shaft is installed by installing the hollow cylinder and the connecting flange through the kneading cylinder. It can be installed separately and combined, which is conducive to supporting rotation and can be ventilated for operation, which is efficient and stable.

[0017] (3) A right-angle tube is installed through the bellows, which can be inserted into the hollow shaft to facilitate ventilation and air intake. It can also assist in heating and cooling, improve the safety of kneading, and make it convenient to adjust and use. Attached Figure Description

The outer surface of the texturing cylinder 14 is provided with an annular platform 15, and the interior of the texturing cylinder 14 is provided with a cavity 16. The surface of the annular platform 15 is provided with an arc-shaped groove 17, and the interior of the arc-shaped groove 17 is provided with a positioning insertion hole 18. An arc-shaped plate 2 is engaged inside the arc-shaped groove 17. The texturing pattern is set on the surfaces of the annular platform 15 and the arc-shaped plate 2. The machine can be rotated for convenient, precise, and stable texturing of leather. The two ends of the arc-shaped plate 2 are provided with limiting platforms 21, and the lower surface of the arc-shaped plate 2 is fixedly connected with a plug rod 22, which can be separately inserted and positioned, thereby separately installing the arc-shaped plate 2 onto the annular platform 15. The ring platform 15 is designed for easy assembly onto the surface of the kneading drum 14. This design allows for disassembly, cleaning, and maintenance. Furthermore, inserting the rod 22 into the cavity 16 increases the internal heat exchange area, efficiently transferring heat to the surface of the ring platform 15. This design facilitates assembly and offers high adaptability. One end of the rod 22 has a positioning hole 23, which is inserted into the positioning hole 18. One end of the kneading drum 14 has a threaded hole 24, into which a long positioning rod 25 is threaded and inserted into the positioning hole 23.
