Description

Technical Field

[0001] The invention relates to the technical field of leather dyeing, in particular to a movable temporary leather unwinding device. Background Art

[0002] Leather is a denatured and non-perishable animal skin obtained through physical and chemical processing such as dehairing and tanning. Leather is composed of natural protein fibers tightly woven in three-dimensional space. Its surface has a special grain layer with natural grain and luster and feels comfortable. As one of the more important materials in life and industry, leather requires the use of an unwinding device during its processing.

[0003] However, as far as the currently available leather unwinding devices are concerned, the leather is mostly rolled up and stored by rollers. Since the contact surface between the leather and the rollers is relatively smooth, the leather is easy to slip on the surface of the rollers, causing the temperature inside the leather to rise due to the friction, which has a certain impact on the quality of the leather. In addition, when the device is moved, the leather roll is also prone to loosening due to the sliding of the leather roll, which is easy to cause wrinkles on the leather during the unwinding process. At the same time, the existing leather unwinding devices are mostly fixed devices when in use. Since the unwinding mechanism is mostly a metal structure as a whole, it is heavy and not easy to move.

[0012] Beneficial Effects

[0013] 1. In the present invention, the fixed block limits the installation roller during the leather unwinding process to prevent the installation roller from being offset. At the same time, the installation roller can be tightened by inserting the fixed block. During the movement of the device, the installation roller can be prevented from rotating. The support plate is connected to the connecting piece by a spring. In the unwinding mechanism, one end of the leather is fixed by the locking piece of the fixed plate, and then the leather is wound around the fixed plate and the outer side of the support plate. At the same time, the support plate has a certain elasticity. After the leather is wound, the elasticity of the support plate makes the support plate fit closely to the inner surface of the leather, ensuring the friction between the unwinding mechanism and the inner surface of the leather. At the same time, the fixed block fixes the installation roller to prevent the leather from rotating and loosening on the unwinding mechanism, preventing the inner surface of the leather from heating up due to friction, affecting the quality of the leather, and preventing the leather from loosening on the unwinding mechanism. When the leather is sent out through the support roller, wrinkles are generated, ensuring the quality of the leather.

[0014] 2. In the present invention, the universal wheel enables the device to be moved more conveniently. After the device moves to the working position, the thread of the rotating rod is rotated, and the thread of the rotating rod cooperates with the thread of the screw hole of the limit bracket, so that the limit bracket moves downward, and the friction piece at the lower end of the limit bracket contacts the ground, thereby increasing the friction between the device as a whole and the ground, so that the device is fixed in the working position. At the same time, the limit bracket has a certain supporting capacity. When in use, it can reduce the pressure of the device as a whole on the universal wheel, and increase the service life of the universal wheel. At the same time, compared with the brake-type fixing method commonly used now, the fixing of the device is more stable, and the displacement of the device caused by brake damage is also avoided;

[0015] 3. In the present invention, the limit bracket of the device is mounted on the outside of the mounting bracket, and there is a certain space margin between the limit bracket and the mounting bracket, which can provide a buffer space for accidental side impact and provide certain protection for parts of the device such as the support roller that are more susceptible to damage.
