Description

Technical Field

[0001] This utility model relates to the field of leather production, and in particular to a leather feeding mechanism that can be applied to the production of polyvinyl chloride artificial leather, thermoplastic polyolefin artificial leather, etc. Background Technology

[0002] With the development of automotive technology, people's demands for the comfort of car interiors are increasing. Currently, leather is mainly used as the primary material for car interiors to improve their texture and comfort.

[0003] To improve the texture, breathability, heat dissipation, and slip resistance of leather, perforation is required during leather processing. During perforation, a layer of cardboard is typically placed underneath the leather to protect the perforating tools and the leather. After perforation, the leather and cardboard are rolled up. Before perforation, a leather feeding mechanism flattens the leather to facilitate subsequent perforation. Utility Model Content

[0004] The purpose of this invention is to solve the technical problem of flattening leather for subsequent perforation. This invention provides a leather feeding mechanism that uses an active roller and a first passive roller to apply tension to the leather, eliminating wrinkles on the leather surface and automatically flattening the leather during transport, thus facilitating subsequent perforation.

[0005] To address the aforementioned technical problems, this utility model discloses a leather feeding mechanism for supplying leather to a leather processing device. The leather feeding mechanism includes:

[0006] First support;

[0007] An active roller extends along the width direction, and its two ends are rotatably connected to the first bracket.

[0008] The first passive roller extends along the width direction and its two ends are rotatably connected to the first bracket. Along the height direction, the active roller and the first passive roller are spaced apart to form a first receiving gap. The first receiving gap is used for leather to pass through and to contact the active roller and the first passive roller respectively.

[0009] The feeding roller is axially rotatable about the width direction. The feeding roller is used to place a leather roll, and the leather roll is used to supply leather to the first receiving gap. Along the length direction, the active roller, the first passive roller and the feeding roller are spaced apart. The length direction, the width direction and the height direction are perpendicular to each other.

[0010] The drive roller is used to move the leather toward the leather processing device.

[0011] Using the above technical solution, the active roller rotates axially in the width direction. During the conveying process, the leather passes through the first receiving gap formed by the active roller and the first passive roller, and comes into contact with both. During transmission, the rotation of the active roller drives the leather towards the leather processing device, and simultaneously, the movement of the leather drives the first passive roller to rotate. This transmission method can stably and continuously convey the leather along a predetermined path. At the same time, the tension applied to the leather by the active roller and the first passive roller eliminates wrinkles on the leather surface, achieving automatic flattening of the leather during transmission, facilitating subsequent perforation of the leather.

[0012] According to another specific embodiment of the present invention, the leather feeding mechanism includes a first motor, which is connected to the active roller to drive the active roller to rotate axially about the width direction.

[0013] According to another specific embodiment of the present invention, the leather feeding mechanism includes a second support and a cutting part. Along the length direction, the second support is disposed between the drive roller and the feeding roller, and the cutting part is disposed on the second support. The cutting part includes:

[0014] The cutting element is disposed at intervals at both ends of the second bracket along the width direction, and the cutting element is used to cut leather;

[0015] A second motor, connected to the cutting element, drives the cutting element to cut the leather.

[0016] Using the above technical solution, the cutting component cuts the edges of the leather, which on the one hand removes rough and irregular parts of the leather edges, making them smooth and neat. On the other hand, it can also cut the leather width to the required size range according to production needs, thereby improving the quality and processing precision of the finished leather product and meeting the requirements of subsequent processes.

[0017] According to another specific embodiment of the present invention, the leather feeding mechanism includes two tension holding parts. Along the length direction, the two tension holding parts are respectively disposed at both ends of the second bracket. The two tension holding parts are used to flatten the leather so that the cutting member can cut the leather.

[0018] According to another specific embodiment of the present invention, the tension holding part includes:

[0019] The second passive roller extends along the width direction, and its two ends are rotatably connected to the second bracket. Along the height direction, the second passive roller is lower than the active roller.

[0020] The third passive roller extends along the width direction and its two ends are rotatably connected to the second bracket. Along the height direction, the second passive roller and the third passive roller are spaced apart to form a second receiving gap for the leather to pass through and to contact the second passive roller and the third passive roller respectively.

[0021] Using the above technical solution, the leather passes through the second receiving gap and comes into contact with the second and third passive rollers respectively. In conjunction with the above, the active roller rotates to drive the leather to move, and then the leather drives the second and third passive rollers to rotate. The active roller and the second and third passive rollers apply tension to the leather, eliminating wrinkles on the leather surface and realizing automatic flattening of the leather during the transmission process, which facilitates the subsequent punching of the leather.

[0022] In addition, by having the second passive roller positioned below the active roller, the leather is made to form an inclined transport path, which enhances the tension of the leather, further eliminates surface wrinkles and unevenness, and improves the smoothness of the leather during transport.

[0023] According to another specific embodiment of the present invention, the two tension holding parts are located at the same height.

[0024] With the above technical solution, the two tension holding parts are located at the same height, so as to better flatten the leather and facilitate the cutting parts to cut the leather.

[0025] According to another specific embodiment of the present invention, the leather feeding mechanism includes a fourth passive roller, which extends along the width direction and is rotatably connected to the second bracket at both ends. Along the width direction, the fourth passive roller is disposed between the tension holding part and the feeding roller. Along the height direction, the fourth passive roller is lower than the tension holding part and the feeding roller. The fourth passive roller is used to contact the leather.

[0026] Using the above technical solution, combined with the foregoing, the active roller drives the leather to move toward the leather processing device, and then the leather drives the second passive roller and the fourth passive roller to rotate. During this process, the active roller, the second passive roller, and the fourth passive roller apply tension to the leather, which can eliminate wrinkles on the leather surface and realize the automatic flattening of the leather during the transmission process, making it easier to process the leather in the future.

[0027] Furthermore, since the fourth passive roller is lower than the tension holding section, it can form an inclined transport path for the leather. As a result, when the leather passes through the fourth passive roller, the fourth passive roller has a limiting effect on the leather, which can increase the tension of the leather, further eliminate surface wrinkles and unevenness, and improve the smoothness of the leather during the transport process.

[0028] According to another specific embodiment of the present invention, the cutting part includes:

[0029] A lead screw that extends along the width direction;

[0030] A slider is connected to the cutting component, and the slider is slidably connected to the lead screw along the width direction;

[0031] A driving component is connected to the lead screw to drive the lead screw to rotate axially about the width direction.

[0032] Using the above technical solution, the sliding connection between the slider and the lead screw drives the cutting parts to slide along the width direction, thereby adjusting the distance between the two cutting parts and thus adjusting the width of the leather.

[0033] According to another specific embodiment of the present invention, the active roller and the first passive roller are rubber rollers.

[0034] By adopting the above technical solution, the leather is protected from damage through the flexible contact between the rubber roller and the leather.

[0035] According to another specific embodiment of the present invention, the second passive roller, the third passive roller and the fourth passive roller are rubber rollers.

[0036] By adopting the above technical solution, the leather is protected from damage through the flexible contact between the rubber roller and the leather. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this embodiment based on the specific circumstances.

[0057] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0058] refer to Figures 1 to 3 This application provides a leather feeding mechanism 400, which is used to convey leather 104 to a leather processing device (not shown) for punching holes in the leather 104.

[0059] To facilitate a detailed description of the structure of the leather feeding mechanism 400, the length direction X, width direction Y, and height direction Z of the leather feeding mechanism 400 are defined here, wherein the length direction X, width direction Y, and height direction Z are perpendicular to each other.

[0060] For example, the leather feeding mechanism 400 includes a power unit 410, a feeding roller 420, and a feeding bracket 421. The power unit 410 includes a first bracket 411, a drive roller 412, and a first passive roller 413.

[0061] For example, the feeding roller 420 is rotatably connected to the feeding bracket 421, and the feeding roller 420 is axially rotatable about the width direction Y. A leather roll 105 is placed on the feeding roller 420, and the leather roll 105 can provide leather 104.

[0062] The feed roller 420 is used to supply leather 104 to the power unit 410. Along the length direction X, the drive roller 412, the first passive roller 413 and the feed roller 420 are arranged at intervals.

[0063] The driving roller 412 extends along the width direction Y, and its two ends are rotatably connected to the first support 411. The driving roller 412 is axially rotatable about the width direction Y. The first passive roller 413 extends along the width direction Y, and its two ends are rotatably connected to the first support 411. Along the height direction Z, the driving roller 412 and the first passive roller 413 are spaced apart to form a first receiving gap 415. The first receiving gap 415 is used for the leather 104 to pass through, and the driving roller 412 and the first passive roller 413 together clamp the leather 104 located in the first receiving gap 415, so as to drive the leather 104 to move along the length direction X toward the leather processing device (e.g., Figure 1 and Figure 2 (As shown in the X1 direction).

[0064] It should be noted that "clamping" means that the active roller 412 and the first passive roller 413 are in contact with the leather 104 respectively, and the rotation of the active roller 412 can drive the leather 104 to move along the length direction X toward the leather processing device.

[0065] Using the above technical solution, the leather 104 passes through the first receiving gap 415 formed by the active roller 412 and the first passive roller 413, and is clamped by the active roller 412 and the first passive roller 413. The rotation of the active roller 412 drives the clamped leather 104 to move along the length direction X. At the same time, the movement of the leather 104 along the length direction X drives the first passive roller 413 to rotate synchronously. This transmission method can stably drive the leather 104 to be continuously conveyed along a predetermined path. At the same time, the active roller 412 and the first passive roller 413 apply tension to the leather 104, eliminating wrinkles on the surface of the leather 104 and realizing automatic flattening of the leather 104 during the transmission process, which facilitates the subsequent perforation of the leather 104.

[0066] In some possible implementations, refer to Figures 1 to 3 The power unit 410 includes a first motor 414, which is connected to the drive roller 412 to drive the drive roller 412 to rotate.

[0067] In some possible implementations, refer to Figures 1 to 3 The leather feeding mechanism 400 includes a second support 430 and a cutting part 440. Along the length direction X, the second support 430 is located between the drive roller 412 and the feeding roller 420, and the cutting part 440 is located in the second support 430.

[0068] The cutting unit 440 includes two cutting elements 441 and two second motors 442. Along the width direction Y, the two cutting elements 441 are respectively spaced at both ends of the second bracket 430. The cutting elements 441 are used to cut the leather 104. Each second motor 442 is connected to one cutting element 441 to drive the cutting element 441 to cut the leather 104.

[0069] Using the above technical solution, the cutting component 441 cuts the edge of the leather 104, which on the one hand removes rough and irregular parts from the edge of the leather 104, making the edge smooth and neat. On the other hand, it can also cut the width of the leather 104 to the required size range according to production needs, thereby improving the quality and processing precision of the finished leather 104 and meeting the requirements of subsequent processes.

[0070] In some possible implementations, refer to Figures 1 to 3 The leather feeding mechanism 400 includes two tension holding parts 450 along the length direction X. The two tension holding parts 450 are respectively disposed at both ends of the second bracket 430. The two tension holding parts 450 are used to flatten the leather 104 so that the cutting piece 441 cuts the leather 104.

[0071] It should be noted that the number of tension holding parts 450 is not specifically limited in this application embodiment. For example, in other possible implementations, the number of tension holding parts 450 may be three, four, etc.

[0072] In some possible implementations, refer to Figures 1 to 3 The tension holding part 450 includes a second passive roller 451 and a third passive roller 452. The second passive roller 451 extends along the width direction Y. Both ends of the second passive roller 451 are rotatably connected to the second bracket 430. Along the height direction Z, the second passive roller 451 is lower than the active roller 412.

[0073] The third passive roller 452 extends along the width direction Y, and its two ends are rotatably connected to the second bracket 430. Along the height direction Z, the second passive roller 451 and the third passive roller 452 are spaced apart to form a second receiving gap 453, which is used for the leather 104 to pass through and to contact the second passive roller 451 and the third passive roller 452 respectively.

[0074] Using the above technical solution, the leather 104 passes through the second receiving gap 453 and contacts the second passive roller 451 and the third passive roller 452 respectively. In conjunction with the above, the active roller 412 rotates to drive the leather 104 to move, and then the leather 104 drives the second passive roller 451 and the third passive roller 452 to rotate. The active roller 412 and the second passive roller 451 and the third passive roller 452 apply tension to the leather 104 to eliminate wrinkles on the surface of the leather 104, realize the automatic flattening of the leather 104 during the transmission process, and facilitate the subsequent punching of the leather 104.

[0075] In addition, by lowering the second passive roller 451 below the active roller 412, the leather 104 is made to form an inclined conveying path, which enhances the tension on the leather 104, further eliminates surface wrinkles and unevenness, and improves the flatness of the leather 104 during the conveying process.

[0076] In some possible implementations, the two tension holding parts 450 are located at the same height.

[0077] With the above technical solution, the two tension holding parts 450 are located at the same height, so as to better flatten the leather 104 and facilitate the cutting part 441 to cut the leather 104.

[0078] It should be noted that the positional relationship between the two tension holding parts 450 is not specifically limited in this embodiment. For example, in other possible implementations, it may be as follows: Figure 2 The two tension holding parts 450 shown have a height difference, and the specific positional relationship between the two tension holding parts 450 is determined by the on-site operator.

[0079] In some possible implementations, refer to Figures 1 to 4 The leather feeding mechanism 400 includes a fourth passive roller 460, which extends along the width direction Y and is rotatably connected to the second bracket 430 at both ends. Along the length direction X, the fourth passive roller 460 is located between the tension holding part 450 and the feeding roller 420. Along the height direction Z, the fourth passive roller 460 is lower than the tension holding part 450 and the feeding roller 420. The fourth passive roller 460 is used to contact the leather 104.

[0080] Using the above technical solution, combined with the foregoing, the rotation of the active roller 412 drives the leather 104 to move, and then the leather 104 drives the second passive roller 451 and the fourth passive roller 460 to rotate. The active roller 412 and the second passive roller 451 and the fourth passive roller 460 apply tension to the leather 104, eliminating wrinkles on the surface of the leather 104 and realizing the automatic flattening of the leather 104 during the transmission process, which facilitates the subsequent punching of the leather 104.

[0081] Furthermore, by lowering the fourth passive roller 460 below the tension holding section 450, the leather 104 can be effectively made to form an inclined transmission path, which enhances the tension of the leather 104, further eliminates surface wrinkles and unevenness, and improves the flatness of the leather 104 during the transmission process.

[0082] In some possible implementations, refer to Figures 1 to 4 The cutting unit 440 includes a lead screw 443, a slider 444, and a drive member 445. The lead screw 443 extends along the width direction Y. The slider 444 is connected to the cutting member 441 and is slidably connected to the lead screw 443 along the width direction Y. The drive member 445 is connected to the lead screw 443 and drives the lead screw 443 to rotate axially about the width direction Y.

[0083] Using the above technical solution, the sliding connection between the slider 444 and the lead screw 443 drives the cutting piece 441 to slide along the width direction Y, thereby adjusting the distance between the two cutting pieces 441 and thus adjusting the width of the leather 104.

[0084] In some possible implementations, refer to Figures 1 to 4 The active roller 412 and the first passive roller 413 are rubber rollers.

[0085] By adopting the above technical solution, the rubber roller makes flexible contact with the leather 104, thus avoiding damage to the leather 104.

[0086] In some possible implementations, refer to Figures 1 to 4 The second passive roller 451, the third passive roller 452 and the fourth passive roller 460 are rubber rollers.

[0087] By adopting the above technical solution, the rubber roller makes flexible contact with the leather 104, thus avoiding damage to the leather 104.
