[0026] The leather cutting and feeding mechanism described in the present invention cooperates with the unwinding mechanism 100 through the leather processing table 200 to realize continuous feeding, and then the leather is pressed and cut by the positioning cutting mechanism 300, thereby reducing the possibility of wrinkles during the cutting process. After cutting, the leather is clamped and fixed from different directions by the anti-wrinkle mechanism 400, thereby further improving the flatness of the leather during subsequent transportation, thereby minimizing the possibility of wrinkles on the leather. Compared with conventional leather processing equipment at this stage, the present application has the advantages of high degree of automation, high degree of integration, high processing efficiency and can greatly reduce leather wrinkles.

[0027] See also Figure 1 As shown, for the convenience of description, in this embodiment, the direction of leather material transmission in the horizontal plane is defined as the first direction X, the width direction of the leather material cutting and feeding mechanism is defined as the second direction Y, and the height direction of the leather material cutting and feeding mechanism is defined as the third direction Z, wherein the first direction X, the second direction Y and the third direction Z are arranged perpendicular to each other, and the first direction X and the second direction Y are located in the same plane. In this embodiment, the unwinding mechanism 100 is used to transmit the rolled leather material 500 to be processed to the leather material processing table 200, and the positioning and cutting mechanism 300 and the anti-wrinkle mechanism 400 are both arranged on the leather material processing table 200, wherein the positioning and cutting mechanism 300 is used to cut the leather material 500 to be processed of a predetermined size under the condition of extrusion and fixing, and the anti-wrinkle mechanism 400 is used to fix the cut leather material from different directions to achieve the flatness of the leather material in the subsequent processing process.

[0028] In this embodiment, the unwinding mechanism 100 also includes an unwinding bracket 110 and a connecting shaft 120. The connecting shaft 120 is arranged on the unwinding bracket 110, and the leather material 500 to be processed is wound on the unwinding bracket 110. During the actual processing process, the rolled leather material 500 to be processed is sleeved on the connecting shaft 120, and the two adjacent rolls of leather are connected by aluminum foil tape, thereby realizing uninterrupted feeding.

[0029] See also Figure 1 and Figure 2 As shown, the conveying surface 210 of the leather processing table 200 is a rectangular table, which is fixed on the mounting surface through a frame. A roller is provided on the side of the conveying surface 210 facing the unwinding mechanism 100, which is used to support the leather so that the leather is in a relatively tight state, thereby facilitating transmission. Further, the leather processing table 200 includes a first frame 220 and two transmission rollers 230. The first frame 220 is arranged above the conveying surface 210. The two transmission rollers 230 are respectively connected to the first frame 220 and are arranged at intervals along the third direction Z. Any of the transmission rollers 230 extends along the second direction Y, and the leather 500 to be processed moves between the two transmission rollers 230. The transmission rollers 230 are respectively rotated around their respective axes by driving motors. On the one hand, they are used to provide transmission power for the leather 500 to be processed. On the other hand, they can also perform preliminary rolling of the leather 500 to be processed for subsequent cutting. Specifically, the spacing distance between the two transmission rollers 230 in this embodiment can be set to be slightly smaller than the thickness of the leather 500 to be processed, thereby improving the rolling effect on the leather. In other embodiments, other numbers and positions of transmission rollers 230 can also be set, and the utility model does not impose specific limitations on this.

[0030] In this embodiment, the positioning and cutting mechanism 300 can move along the first direction X relative to the leather processing table 200 to adjust the specific cutting position of the leather according to actual needs. In the first direction X, the positioning and cutting mechanism 300 is arranged on the side of the conveying surface 210 away from the unwinding mechanism 100. The positioning and cutting mechanism 300 includes a second frame 310, and the pressing member 320 and the cutting knife 340 are respectively connected to the opposite sides of the second frame 310, and the cutting knife 340 is arranged close to the anti-wrinkle mechanism 400. Further, the second frame 310 is provided with a first module 311 and a second module 330, the first module 311 extends along the second direction Y, the cutting knife 340 is slidably connected to the first module 311, the second module 330 extends along the third direction Z, and the pressing member 320 is slidably connected to the second module 330. The pressing piece 320 is disposed above the leather processing table 200 and can reciprocate along the third direction Z. Before cutting the leather, the leather with cutting needs to be squeezed and fixed on the leather processing table 200 by the pressing piece 320, thereby improving the stability and cutting accuracy of the leather cutting process. Specifically, the pressing piece 320 in this embodiment is preferably an aluminum profile that can be completely attached to the conveying surface 210, and is driven by a cylinder to realize its movement process.

[0031] Correspondingly, in this embodiment, the first module 311 is connected to the second frame 310, and the cutter 340 realizes the cutting process of the leather by moving along the first module 311. Specifically, the cutter 340 includes a blade and a cutting driver. The blade is connected to the working end of the cutting driver. The blade is preferably circular and realizes the rolling cutting process of the leather by rotating around its center. After the cutting is completed, the pressing part 320 rises to separate from the leather processing table 200 to release the leather.

[0032] See also Figure 3 and Figure 4 As shown, the positioning and cutting mechanism 300 also includes a second sensor and an aluminum foil detection switch, which are respectively connected to the leather processing table 200, wherein the second sensor is arranged toward the conveying surface 210, and the aluminum foil detection switch is arranged toward the unwinding mechanism 100. In the actual processing process, the second sensor is used to detect the flatness of the leather, thereby quantitatively controlling the processing conditions of the leather, and the aluminum foil detection switch is used to detect the connection between two adjacent rolls of leather. When it detects aluminum foil, it means that the previous roll of leather has been used up and needs to be replaced with the next roll of leather. Furthermore, since the leather at the connection of the aluminum foil cannot be used, the aluminum foil detection switch needs to cooperate with the cutting mechanism to cut and remove the material here.

[0033] In this embodiment, the anti-wrinkle mechanism 400 further includes a third module 420 and a mounting plate 430, wherein the third module 420 extends along the second direction Y, the mounting plate 430 is slidably connected to the third module 420, and at least part of the clamping assembly 410 is disposed on the mounting plate 430. Specifically, in this embodiment, three mounting plates 430 are provided, which are respectively disposed on two opposite sides in the first direction X and the second direction Y, wherein the two groups of clamping assemblies 410 disposed in the second direction Y can move relative to each other through the third module 420 to achieve clamping and fixing of the clamped leather material. Further, the clamping assembly 410 includes a clamping driver 411 and at least two clamping plates 412, wherein at least one of the clamping plates 412 is connected to the clamping driver 411 so that the two clamping plates 412 are relatively opened and closed.

[0034] Furthermore, two first sensors 350 are provided at the discharge end of the positioning and cutting mechanism 300. After the leather passes through the first sensor 350, the clamping assembly 410 on the first direction X will clamp the end of the leather. Based on this, the clamping assembly 410 and the pressing piece 320 arranged in the first direction X can clamp and fix the front and rear ends of the leather in the leather transmission direction to maximize the cutting effect. When the cutting is completed, the two sets of clamping assemblies 410 on the second direction Y can clamp and fix the opposite ends of the leather, thereby ensuring that the leather can obtain the corresponding flatness in the second direction Y.

[0035] This embodiment also includes a control system, and the leather processing table 200, the positioning and cutting mechanism 300, and the anti-wrinkle mechanism 400 are respectively connected to the control system. The operator can control the above structures in real time through the control system, thereby improving the flexibility of the application. The parameters of the mechanism can also be preset through the control system before processing, thereby improving the automation of the mechanism. The specific operation process of the leather cutting and feeding mechanism in this embodiment is described below:

[0036] First, the unwinding mechanism 100 transfers the leather to the leather processing table 200, and the leather is moved and transferred along the first direction X through the transmission roller 230. When it reaches the preset position, the first sensor 350 transmits a signal to the clamping assembly 410 arranged in the first direction X, so that it clamps the edge of the leather in the first direction X. At the same time, the pressing member 320 descends and forms a fixation of the leather in the first direction X with the clamping assembly 410 in the first direction X. Next, the cutter 340 cuts the leather to obtain leather of a preset size. After that, the two groups of clamping assemblies 410 located in the second direction Y move along the third module 420, and when they clamp the two ends of the leather in the second direction Y, they move away from each other to transport the target leather to the inside of the device.

[0037] In summary, the leather cutting and feeding mechanism described in the present invention cooperates with the unwinding mechanism 100 through the leather processing table 200 to achieve continuous feeding, and then the leather is pressed and cut by the positioning cutting mechanism 300, thereby reducing the possibility of wrinkles during the cutting process. After cutting, the leather is clamped and fixed from different directions by the anti-wrinkle mechanism 400, thereby further improving the flatness of the leather during subsequent transportation, thereby minimizing the possibility of wrinkles on the leather. Compared with conventional leather processing equipment at this stage, the present application has the advantages of high degree of automation, high degree of integration, high processing efficiency and can greatly reduce leather wrinkles.

[0038] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
