Description

Technical Field

[0001] The invention belongs to the technical field of oscillating softening machines, in particular to an oscillating softening machine for preventing leather from being folded. Background Art

[0002] Leather is a denatured, non-perishable animal hide obtained through physical and chemical processes such as dehairing and tanning. Leather is composed of natural protein fibers tightly woven in three dimensions. Its surface features a unique grain layer, resulting in a natural texture, luster, and pleasant feel. Leather softening is necessary during processing to eliminate stiffness and warping in the leather, making the leather fibers loose, soft, and elastic, effectively improving the quality of the finished product.

[0003] In leather manufacturing, softening is a key process for improving leather's softness and ductility. Traditional softening equipment uses a single-point drive roller to convey the leather. This can lead to uneven power transmission, causing localized slack in the leather, resulting in wrinkles or folds. This is especially true when processing large areas of leather, as traditional techniques struggle to maintain uniform tension, which can affect the subsequent softening process.

[0004] For this reason, we propose an oscillating softening machine that prevents leather from being folded. Summary of the Invention

[0007] In a preferred embodiment of the invention, an outer surface of one end of the second rotating rod is fixedly connected to the output shaft of the motor.

[0008] In a preferred embodiment of the invention, the transmission auxiliary mechanism 1 includes two relatively arranged lower fixed plates, and the lower fixed plates are fixedly connected to the outer surfaces at both ends of the same side of the oscillation and softening mechanism. A rotating rod 3 is rotatably connected between the side surfaces of the two lower fixed plates via a bearing, and the outer surface of the rotating rod 3 is fixedly connected to the lower auxiliary roller.

[0009] In a preferred embodiment of the invention, the transmission auxiliary mechanism 2 includes two relatively arranged upper fixed plates, which are fixedly connected to the outer surfaces at both ends of the same side of the oscillation and softening mechanism. A rotating rod 4 is rotatably connected between the side surfaces of the two upper fixed plates via a bearing, and the outer surface of the rotating rod 4 is fixedly connected to an upper auxiliary roller.

[0010] In a preferred embodiment of the invention, the oscillation and softening mechanism includes an upper oscillation plate and a lower oscillation plate, the lower oscillation plate is installed on the upper surface of the connecting bracket, the upper surface of the lower oscillation plate is installed with a reinforced nylon hole plate, the upper oscillation plate is installed directly above the reinforced nylon hole plate through a fixing frame, and the lower surface of the reinforced nylon tooth plate is installed with a reinforced nylon hole plate.

[0011] In a preferred embodiment of the invention, the tooth pins on the lower surface of the reinforced nylon tooth plate are vertically meshed with the tooth pin holes on the upper surface of the reinforced nylon hole plate.

[0012] In a preferred embodiment of the invention, the oscillation softening mechanism is provided with six oscillation zones in sequence from left to right, and each of the oscillation zones is driven by an independent driving mechanism, and the independent driving mechanism is installed inside the connecting bracket.

[0013] In a preferred embodiment of the invention, the oscillation softening mechanism is provided with six oscillation zones in sequence from left to right, and each of the oscillation zones is driven by an independent driving mechanism, and the independent driving mechanism is installed inside the connecting bracket.

[0014] In a preferred embodiment of the invention, the number of the second rotating rod and the active roller is two, and a gap for the leather to pass through is left between the two active rollers.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In the present invention, when the leather is softened, one side of the leather can pass between the two active rollers at the left end, pass through the upper surface of the guide roller, then pass through the lower end of the transmission auxiliary mechanism 1, and finally pass through the upper end of the transmission auxiliary mechanism 2, and then pass through the oscillation softening mechanism and be pulled to the right end and pass through the transmission auxiliary mechanism 2, the transmission auxiliary mechanism 1, the guide roller and the active roller, so as to facilitate transmission when the leather is softened; during transmission, the guide roller, the transmission auxiliary mechanism 1 and the transmission auxiliary mechanism 2 can not only assist in the transmission of the leather, but also make the leather in a relatively straight state, which is convenient for the oscillation softening mechanism to soften the leather, and try to avoid the problem of leather folding caused by power loss during transmission; through the cooperation of the above structures, try to avoid the leather folding caused by power loss during transmission, and improve the processing efficiency of leather softening.

[0016] 2. In the present invention, the reinforced nylon toothed plate installed on the bottom surface of the upper oscillation plate oscillates vertically with the mechanical high frequency, and the tooth nails of the upper oscillation plate penetrate the surface of the leather. During movement, the tooth nails hook the upper fibers of the leather and vertically stretch them to separate the fibers longitudinally. The reinforced nylon hole plate installed on the upper surface of the lower oscillation plate can provide a static support surface, and the tooth nail holes on the reinforced nylon hole plate can guide the tooth nails to penetrate the leather, limit the lateral displacement of the fibers, avoid excessive tearing, convert mechanical energy into internal energy of the fibers, break the rigid connection of the collagen fiber bundles, and utilize six oscillation zones to uniformly soften the entire leather, reduce surface damage, and thus improve the processing efficiency when the leather is softened.

[0017] 3. This invention utilizes a zoned, independent drive mechanism. By setting up six oscillation zones driven by independent drive mechanisms, the amplitude and frequency can be adjusted according to the thickness of the leather, achieving targeted softening treatment. Furthermore, the vertical meshing design of the reinforced nylon tooth plate and the reinforced nylon hole plate generates a multi-dimensional kneading force during oscillation. Compared with traditional metal tooth structures, this can reduce the probability of scratching the leather surface, thereby preventing the scratched leather from warping and buckling.

Example 2

[0024] Reference Figures 1-4 The oscillation softening mechanism 3 includes an upper oscillation plate 31 and a lower oscillation plate 33. The lower oscillation plate 33 is mounted on the upper surface of the connecting bracket 2. A reinforced nylon hole plate 34 is mounted on the upper surface of the lower oscillation plate 33. The upper oscillation plate 31 is mounted directly above the reinforced nylon hole plate 34 through a fixing frame, and a reinforced nylon hole plate 34 is mounted on the lower surface of the reinforced nylon tooth plate 32. Specifically, when the leather is softened, the reinforced nylon tooth plate 32 mounted on the bottom surface of the upper oscillation plate 31 oscillates vertically with the mechanical high frequency, and the teeth of the upper oscillation plate 31 pierce The teeth nails penetrate into the leather surface, and when in motion, they hook the upper fibers of the leather and stretch them vertically to separate the fibers longitudinally.

[0025] Reference Figures 1-4 The oscillation softening mechanism 3 is provided with six oscillation zones from left to right, and each oscillation zone is driven by an independent driving mechanism, which is installed inside the connecting bracket 2; the tooth nails on the lower surface of the reinforced nylon tooth plate 32 are vertically meshed with the tooth nail holes on the upper surface of the reinforced nylon hole plate 34; specifically, it adopts a partitioned independent drive, and by setting six oscillation zones driven by independent driving mechanisms, the amplitude frequency can be adjusted according to the thickness difference of the leather to achieve targeted softening treatment, and the vertical meshing of the reinforced nylon tooth plate 32 and the reinforced nylon hole plate 34 generates a multi-dimensional kneading force during oscillation. Compared with the traditional metal tooth structure, it can reduce the probability of scratching the leather surface, thereby preventing the scratched leather from curling up and folding.

[0026] The implementation principle of the oscillating softening machine for preventing leather from being folded in the present application is as follows: When using the device, first connect to an external power source. When softening the leather, one side of the leather can pass between the two active rollers 45 at the left end, pass through the upper surface of the guide roller 43, then pass through the lower end of the transmission auxiliary mechanism 1 5, and finally pass through the upper end of the transmission auxiliary mechanism 2 6, and then pass through the oscillation softening mechanism 3 and be pulled to the right end and pass through the transmission auxiliary mechanism 2 6, the transmission auxiliary mechanism 1 5, the guide roller 43 and the active roller 45, so as to facilitate transmission when softening the leather; during transmission, the guide roller 43, the transmission auxiliary mechanism 1 5 and the transmission auxiliary mechanism 2 6 can not only assist in the transmission of the leather, but also make the leather in a relatively straight state, which is convenient for the oscillation softening mechanism 3 to soften, and try to avoid the problem of leather folding caused by power loss during transmission; through the cooperation of the above structures, try to avoid the leather folding caused by power loss during transmission, and improve the processing efficiency of leather softening.

[0027] When softening the leather, the reinforced nylon tooth plate 32 installed on the bottom surface of the upper oscillation plate 31 oscillates vertically with the mechanical high frequency, and the tooth nails of the upper oscillation plate 31 penetrate the surface of the leather. During movement, the tooth nails hook the upper fibers of the leather and vertically stretch the fibers to separate them longitudinally. The reinforced nylon hole plate 34 installed on the upper surface of the lower oscillation plate 33 can provide a static support surface, and the tooth nail holes on the reinforced nylon hole plate 34 can guide the tooth nails to penetrate the leather, limit the lateral displacement of the fibers, avoid excessive tearing, convert mechanical energy into fiber internal energy, break the rigid connection of the collagen fiber bundles, and use six oscillation zones to evenly soften the entire leather, reduce surface damage, and thus improve the processing efficiency when softening the leather.

[0028] On the other hand, it adopts partitioned independent drive and sets up six oscillation zones driven by independent drive mechanisms. The amplitude frequency can be adjusted according to the thickness difference of the leather to achieve targeted softening treatment. The vertical meshing design of the reinforced nylon tooth plate and the reinforced nylon hole plate generates multi-dimensional kneading force during oscillation. Compared with the traditional metal tooth structure, it can reduce the probability of scratching the leather surface, thereby preventing the scratched leather from curling up and folding.
