[0002] Natural leather is relatively hard. When entering production, the leather must be softened. The softened leather is soft, plump and elastic.

[0003] The process of leather softening requires first applying leather softener on the surface of the leather after scraping and depilation, then beating or rolling the leather softener into the leather through the pores on the surface and evenly distributing it on the surface of the leather fibers, thus achieving the purpose of softening.

[0004] Softening by hammering can easily damage the surface of the leather; at the same time, the processing efficiency is low, which is suitable for the production of personal handmade leather products;

[0005] During the softening process by rolling in factory production, when the leather enters the rolling roller, manual placement can easily cause the leather to be placed unevenly. At the same time, after a part of the leather enters the rolling roller, it is easy to deviate under the rotation of the rolling roller, and the part that has not entered the rolling roller is prone to bulge, which makes it easy for the leather to fold in the rolling roller, which can easily lead to uneven rolling and softening. After softening, creases appear on the leather surface, and the softening effect of the folded part is not good;

[0006] Based on this, the present invention designs an environmentally friendly leather softening processing system to solve the above-mentioned technical problems. Summary of the invention

[0037] like Figures 1 to 4 As shown,

[0038] Embodiment 1;

[0039] An environmentally friendly leather softening processing system includes a controller, a conveyor belt 1 and a rolling roller, wherein both sides of the conveyor belt 1 are mounted on a conveying bracket 3; the rolling roller is arranged at the output end of the conveyor belt 1; rolling brackets 4 are arranged on both sides of the rolling roller, and the rolling roller is rotatably connected to the rolling bracket 4. The softening processing system also includes:

[0040] A groove 5, wherein the groove 5 is annularly provided on both sides of the conveyor belt 1;

[0041] A pressing and disengaging unit, which is arranged on both sides of the conveyor belt 1, and is used to ensure that the leather is in a straight state during the softening process of the leather passing through the rolling roller, and the pressing part of the pressing and disengaging unit is arranged in the groove 5;

[0042] The rolling roller includes a front rolling roller 21 and a rear rolling roller 22; the front rolling roller 21 is located at one end close to the conveyor belt 1, and the length of the front rolling roller 21 is less than the distance between the pressing and disengaging units on both sides of the conveyor belt 1; the length of the rear rolling roller 22 is not less than the distance between the grooves 5 on both sides of the conveyor belt 1;

[0043] During the leather softening process, workers manually put the leather directly into the rolling roller, which is easy to cause wrinkles and uneven rolling and softening. The present invention sets a pressing and disengaging unit to first place the leather to be softened on the conveyor belt 1, and then presses and fixes the four corners of the leather respectively through the pressing part of the pressing and disengaging unit in the groove 5; the controller then controls the conveyor belt 1 to work, and when one end of the leather moves to the position of the front rolling roller 21, the disengaging part of the pressing and disengaging unit works to make the pressing part disengage from the leather, and one end of the leather enters the front conveying roller and the rear conveying roller in turn, and the other end of the leather is fixed by the pressing part in the pressing and disengaging unit, so that the leather remains straight and is not easy to wrinkle during the rolling and softening process; when the other end of the leather also moves to the position of the front rolling roller 21, the disengaging part of the pressing and disengaging unit makes the pressing part disengage from the leather, and the other end of the leather also enters the front conveying roller and the rear conveying tube in turn; the entire leather completes the rolling and softening process;

[0044] The present invention provides a pressing and disengaging unit so that the leather can always be kept in a pulled straight state during the softening process, thereby making the softening process more uniform.

[0045] As an embodiment of the present invention, the pressing and releasing unit comprises:

[0046] A compression spring 61, wherein the compression spring 61 is evenly arranged in the groove 5;

[0047] A pressing piece 62, wherein the pressing piece 62 is rotatably connected to the upper end of the compression spring 61;

[0048] A push piece 63, wherein the push piece 63 is fixedly connected to a position corresponding to the pressing piece 62 at one end of the rolling support 4 facing the conveyor belt 1;

[0049] During the leather softening process, the leather is first placed on the conveyor belt 1, and the pressing piece 62 is pulled to stretch the compression spring 61, and one corner of the leather is smoothed and then the pressing piece 62 is put down, so that the pressing piece 62 presses one corner of the leather, and this operation is repeated to press and fix the four corners of the leather; when one end of the leather moves to the position of the front end rolling roller 21, the pressing piece 62 also moves to contact with the pushing piece 63, as the pressing piece 62 gradually approaches the pushing piece 63, the pushing piece 63 pushes the pressing piece 62 to rotate in the direction away from the pushing piece 63, until the pressing piece 62 rotates to a state parallel to the pushing piece 63, the pressing piece 62 detaches from the leather, and one end of the leather enters the front end conveying roller and the rear end conveying roller in turn, ensuring that the leather is not prone to wrinkles during the rolling and softening process, so that the softening is more uniform.

[0050] As an embodiment of the present invention, a ball 621 is provided at the lower end of the pressing sheet 62 for rolling;

[0051] By arranging a ball 621 at the lower end of the pushing pressing plate 62, when the pushing plate 63 pushes the pressing plate 62 to rotate and detach from the leather, the ball 621 converts the sliding friction between the pressing plate 62 and the leather into rolling friction, thereby reducing the friction between the pressing plate 62 and the leather, and reducing the damage to the leather caused by the pressing plate 62 when detaching, thereby ensuring that the leather surface is not scratched.

[0052] As an embodiment of the present invention, a rotating block 7 is fixedly connected to one side of the front end rolling roller 21, and a sliding frame 8 is provided in cooperation with the position of the conveying bracket 3 corresponding to the rotating block 7; the sliding frame 8 is slidably connected to a sliding block 81 toward one end of the rotating block 7; a reset module 82 is provided at the lower end of the sliding block 81 and the bracket of the sliding frame 8, and a lower pressing strip 83 is fixedly connected to the side of the sliding block 81 toward the conveyor belt 1;

[0053] When one end of the leather enters the front-end rolling roller 21, the controller controls the front-end rolling roller 21 to rotate and drive the leather to move. The front-end rolling roller 21 rotates and drives the rotating block 7 to rotate. When the rotating block 7 rotates to contact the sliding block 81, the rotating block 7 continues to rotate and drives the sliding block 81 to move downward and then disengage from the sliding block 81; the sliding block 81 moves downward and drives the lower pressure strip 83 to move downward to press the leather. The pressing of the leather by the lower pressure strip 83 can play a certain role in softening the leather; at the same time, the lower pressure strip 83 is pressed onto the leather, and the rolling roller drives one end of the leather to move, and the lower pressure strip 83 has the effect of flattening the leather that is away from one end of the rolling roller; thereafter, the lower pressure strip 83 returns to its initial state under the action of the reset module 82, and the reset module 82 can use a reset spring to reciprocate in sequence; the effect of softening the leather is further optimized.

[0054] As an embodiment of the present invention, a side of the lower end of the lower pressing strip 83 away from the front end rolling roller 21 is provided with a rounded corner;

[0055] When the lower pressing strip 83 is pressed onto the leather, the pressing roller drives one end of the leather to move, and the leather at the end of the lower pressing strip 83 away from the pressing roller continues to move along the lower pressing strip 83. By setting the rounded corners, the contact area between the leather and the lower pressing strip 83 during the movement is increased, which reduces the possibility of the leather scratching against the lower side of the lower pressing strip 83 to a certain extent, making the surface of the softened leather smoother.

[0056] As an embodiment of the present invention, the lower end of the lower pressing strip 83 is rotatably connected to a lower pressing roller 9;

[0057] By setting the lower pressing roller 9, the leather rotates when it moves through the lower pressing strip 83. While reducing the possibility of the leather scratching the lower side of the lower pressing strip 83, the lower pressing roller 9 also rolls and softens the leather in advance, thereby achieving a better softening effect on the leather.

[0058] As an embodiment of the present invention, a sliding sheet 10 is fixedly connected to the lower end of the compression spring 61, and the sliding sheet 10 is slidably connected to the groove 5;

[0059] By setting the sliding plate 10, when the leather is placed on the conveyor belt 1, the position of the sliding plate 10 can be adjusted according to the length of the leather, so that more leathers of different lengths can be placed for softening treatment, thereby improving the use range of the softening processing system.

[0060] As an embodiment of the present invention, the upper end of the sliding block 81 is fixedly connected to the edge in contact with the rotating block 7 with an arc-shaped sponge pad 11;

[0061] By providing an arc-shaped sponge pad 11, the friction between the rotating block 7 and the sliding block 81 is reduced during the contact process, so that the use time of the rotating block 7 is longer; at the same time, the vibration caused by the sudden loss of pressure of the sliding block 81 when the rotating block 7 is separated from the sliding block 81 is reduced; and the effect of the lower pressure strip 83 pressing on the leather is optimized.

[0062] Embodiment 2:

[0063] The difference between the second embodiment and the first embodiment is that;

[0064] As an embodiment of the present invention, the pressing and releasing unit comprises:

[0065] A torsion spring 64, wherein the torsion spring 64 is evenly arranged in the groove 5;

[0066] A pressing block 65, wherein the pressing block 65 is fixedly connected to the upper end of the compression spring 61, and an inclined surface is arranged at one end of the pressing block 65 facing the laminating roller;

[0067] A push block 66, wherein the push block 66 is fixedly connected to a position corresponding to the pressing piece 62 at one end of the rolling support 4 facing the conveyor belt 1, and an inclined surface matching the pressing block 65 is provided at one end of the push block 66 facing the pressing block 65;

[0068] During the leather softening process, the leather is first placed on the conveyor belt 1, the pressing block 65 is pulled to stretch the torsion spring 64, and one corner of the leather is smoothed and then the pressing block 65 is put down so that the pressing block 65 presses one corner of the leather, and this operation is repeated to press and fix the four corners of the leather; when one end of the leather moves to the position of the front end rolling roller 21, the pressing block 65 moves upward along the inclined surface of the pushing block 66 to separate from the leather, and when the pressing block 65 moves to the upper end of the pushing block 66, the end of the torsion spring 64 away from the pressing block 65 continues to rotate with the conveyor belt 1, and the torsion spring 64 bends to the side under the action of the conveyor belt 1 to separate from the pushing block 66, and then resets to the conveyor belt 1; ensuring that the leather is not prone to wrinkles during the rolling and softening process, making the softening more uniform.

[0069] As an embodiment of the present invention, a side of the lower end of the pressing block 65 away from the pushing block 66 is provided with a rounded corner;

[0070] By providing rounded corners on the pressing block 65, when the pushing block 66 pushes the pressing block 65 away from the leather, the contact area between the rounded corner on the side of the pressing block 65 away from the pushing block 66 and the leather is increased, thereby reducing the squeezing force on the leather when the pressing block 65 moves upward, thereby reducing damage to the leather and ensuring that the leather surface is not scratched.

[0071] The specific workflow is as follows:

[0072] The present invention places the leather on the conveyor belt 1 first, pulls the pressing piece 62 to stretch the compression spring 61, flattens one corner of the leather, and then puts down the pressing piece 62, so that the pressing piece 62 presses the corner of the leather, and repeats this operation to press and fix the four corners of the leather; when one end of the leather moves to the position of the front end rolling roller 21, the pressing piece 62 also moves to contact with the pushing piece 63, as the pressing piece 62 gradually approaches the pushing piece 63, the pushing piece 63 pushes the pressing piece 62 to rotate in the direction away from the pushing piece 63, until the pressing piece 62 rotates to a state parallel to the pushing piece 63, and the pressing piece 62 is separated from the leather. One end of the leather enters the front conveying roller and the rear conveying roller in turn; by arranging a ball 621 at the lower end of the pushing and pressing sheet 62, when the pushing sheet 63 pushes the pressing sheet 62 to rotate and separate from the leather, the ball 621 converts the sliding friction between the pressing sheet 62 and the leather into rolling friction, thereby reducing the friction between the pressing sheet 62 and the leather, and reducing the damage to the leather caused by the pressing sheet 62 when it separates; when one end of the leather enters the front rolling roller 21, the controller controls the front rolling roller 21 to rotate and drive the leather to move, and the front rolling roller 21 rotates and drives the rotating block 7 to rotate, and when the rotating block 7 rotates to the point where it is aligned with the sliding block 8 1, the rotating block 7 continues to rotate and drives the sliding block 81 to move downward and then separate from the sliding block 81; the sliding block 81 moves downward and drives the lower pressing strip 83 to move downward to press the leather, and the lower pressing strip 83 pressing the leather can play a certain role in softening the leather; at the same time, the lower pressing strip 83 presses on the leather, and the rolling roller drives one end of the leather to move, and the lower pressing strip 83 plays a role in flattening the leather away from the end of the lower pressing strip 83 of the rolling roller; then the lower pressing strip 83 returns to its initial state under the action of the reset module 82, and the reset module 82 can use a reset spring to reciprocate in sequence; by setting the lower pressing roller 9, the leather passes through During the movement of the lower pressure strip 83, the lower pressure roller 9 rotates, which reduces the possibility of the leather being scratched against the lower side of the lower pressure strip 83, and at the same time, the lower pressure roller 9 also crushes and softens the leather in advance; by setting the sliding plate 10, when the leather is placed on the conveyor belt 1, the position of the sliding plate 10 can be adjusted according to the length of the leather placed; by setting the arc-shaped sponge pad 11, during the contact process between the rotating block 7 and the sliding block 81, the friction between the two is reduced, so that the rotating block 7 can be used for a longer time; at the same time, the vibration caused by the sudden loss of pressure of the sliding block 81 when the rotating block 7 is separated from the sliding block 81 is reduced.
