Description

Technical Field

[0001] This application relates to the field of leather slitting technology, specifically to a slitting roller local deformation device and slitting equipment. Background Technology

[0002] Leather is animal hide that has undergone physical and chemical processing such as hair removal and tanning, resulting in a modified, less perishable material. It is composed of tightly woven natural protein fibers in a three-dimensional space, with a unique grain layer on its surface, giving it a natural grain and luster, and a comfortable feel. During leather production, the leather needs to be sliced ​​according to customer requirements to meet specific thickness specifications.

[0003] Traditional slitting equipment typically includes slitting rollers to press the leather. Workers manually push the slitting rollers or use a handwheel to rotate them, causing them to press the leather. The leather is then conveyed towards the slitting blades using a conveyor system, where the blades complete the slitting process.

[0004] However, in actual production, the thickness of leather is often not completely uniform; there are usually areas where the leather is thicker and areas where it is thinner. In other words, when slicing the leather, even if the slicing rollers press the leather firmly, because the rollers themselves are flat and the pressure is generally uniform, thinner areas of the leather may not be in contact with the rollers, while thicker areas may be overly compressed. Alternatively, the entire leather may be pressed by the rollers, but due to the uneven thickness, the pressure varies. After slicing, the leather, based on its elastic properties, will rebound, and the degree of rebound will differ depending on the area of ​​pressure. This results in a noticeable uneven thickness remaining in the sliced ​​leather. Utility Model Content

[0005] This application provides a partial deformation device for a slitting roller and a slitting device to improve the problem that the leather after slitting also has obvious uneven thickness due to the uneven thickness of the leather itself.

[0006] In a first aspect, embodiments of this application provide a local deformation device for a segmenting roller, which is used to generate local deformation of the segmenting roller. The local deformation device for the segmenting roller includes a plurality of pressure compensation mechanisms, which are arranged sequentially at intervals along the axial direction of the segmenting roller. The compensation ends of the multiple pressure compensation mechanisms can move toward or away from the dividing roller to increase or decrease the force exerted by the compensation ends on the dividing roller, so that different positions of the dividing roller will produce different degrees of deformation.

[0007] Optionally, the pressure compensation mechanism includes a drive pin, a lead screw, and a push rod. One end of the drive pin is connected to the lead screw, and the end of the lead screw away from the drive pin is sleeved and threaded onto the push rod, so that the push rod moves toward or away from the slitting roller along the axial direction of the lead screw according to the rotation direction of the drive pin.

[0008] Optionally, the pressure compensation mechanism further includes a steering gearbox and a second reduction gearbox. The input end of the steering gearbox is connected to the drive pin, and the output end is connected to the input end of the second reduction gearbox. The output end of the second reduction gearbox is connected to the lead screw.

[0009] Optionally, the pressure compensation mechanism further includes a scale, which is located at the end of the drive pin away from the lead screw.

[0010] Optionally, the partial deformation device of the segmenting roller further includes a secondary crossbeam, which extends along the axial direction of the segmenting roller and is disposed between the top rod and the segmenting roller, so that the force of the top rod is indirectly applied to the segmenting roller through the secondary crossbeam.

[0011] Optionally, the secondary crossbeam is provided with a plurality of deformation auxiliary grooves spaced apart along the axial direction of the segmented roller.

[0012] Optionally, the partial deformation device of the segmenting roller further includes a support roller, which is disposed on the side of the secondary crossbeam facing the segmenting roller and extends along the axial direction of the segmenting roller, and the support roller abuts against the segmenting roller.

[0013] Optionally, the support roller includes multiple support sub-rollers, which are spaced apart along the axial direction of the segmented roller, and each support sub-roller is rotatably connected to the secondary crossbeam.

[0014] Optionally, the direction in which the compensation end of the pressure compensation mechanism moves toward or away from the segmenting roller is the first direction; the segmenting roller local deformation device further includes a plurality of first limiting blocks and a plurality of second limiting blocks arranged sequentially along the axial direction of the segmenting roller, and along the radial direction of the segmenting roller perpendicular to the first direction, the first limiting blocks and the second limiting blocks are respectively disposed on both sides of the segmenting roller and abut against the segmenting roller.

[0015] Secondly, embodiments of this application provide a slitting device, including a slitting roller local deformation device as described in the first aspect.

[0016] Therefore, the embodiments of this application utilize multiple pressure compensation mechanisms to act on different positions of the slitting roller, thereby achieving deformation of the slitting roller. By utilizing the deformation of the slitting roller, the different degrees of compression are formed on different thickness positions of the leather by the slitting roller, so as to adapt to the different thicknesses of the leather at different positions as much as possible and improve the uniformity of the leather after slitting.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] In the description of this application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or specifying the number of technical features indicated. Therefore, features defined with "first" and "second" may explicitly or implicitly include one or more features. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0022] Please see Figures 1 to 7 This application provides a slitting device, including a slitting knife, two slitting rollers 3, and two slitting roller adjusting devices 1. The two slitting rollers 3 are respectively connected to the two slitting roller adjusting devices 1, and the two slitting rollers 3 are arranged opposite each other along a first direction. The slitting knife is located between the two slitting rollers 3, and the space between the two slitting rollers 3 is also used to place leather to be slitted. The slitting rollers 3 can squeeze and fix the leather and assist in conveying it. The first direction refers to the direction in which the slitting rollers 3 face or move away from the leather.

[0023] In some embodiments, see Figure 2The slitting roller adjusting device 1 is used to adjust the position of the slitting roller 3, and includes a main crossbeam 11, a first adjusting mechanism 12, and a second adjusting mechanism 13. The main crossbeam 11 is connected to the slitting roller 3. The first adjusting mechanism 12 is connected to the main crossbeam 11 and is used to adjust the position of the main crossbeam 11 in a first direction. The second adjusting mechanism 13 is connected to the main crossbeam 11 and is used to adjust the position of the main crossbeam 11 in the first direction. The adjustment accuracy of the first adjusting mechanism 12 is less than that of the second adjusting mechanism 13.

[0024] The technical solution provided in this application utilizes a first adjusting mechanism 12 and a second adjusting mechanism 13 to jointly adjust the position of the slitting roller 3, thereby causing the slitting roller 3 to face or move away from the leather to be slitted. Furthermore, the first adjusting mechanism 12 and the second adjusting mechanism 13 have different adjustment accuracies. By coordinating adjustments with different accuracies, rapid and precise adjustment of the position of the slitting roller 3 is achieved, effectively improving the adjustment speed and accuracy of the slitting roller 3. Specifically, the first adjusting mechanism 12 firstly adjusts the position of the main crossbeam 11 in a first direction, which is the direction in which the main crossbeam 11 faces or moves away from the leather to be slitted. Since the main crossbeam 11 is connected to the slitting roller 3, rapid adjustment of the position of the slitting roller 3 is achieved. The reason for rapid adjustment is that the adjustment accuracy of the first adjusting mechanism 12 is lower than that of the second adjusting mechanism 13, allowing the first adjusting mechanism 12 to drive the slitting roller 3 to move a larger displacement, thus enabling rapid adjustment of a large displacement. Then, after the slitting roller 3 is adjusted to the target position by the first adjustment mechanism 12, the distance between the slitting roller 3 and the leather will be very close, or even in contact, at 0 distance. At this time, large displacement adjustment is no longer applicable. The second adjustment mechanism 13 is needed to make small-range precision adjustment to drive the slitting roller 3 to achieve higher precision movement so that the slitting roller 3 can contact the leather and achieve the pressure required for the target slitting thickness.

[0025] In some embodiments, see Figure 3 The first adjustment mechanism 12 includes two first adjustment components, which are respectively located at both ends of the main crossbeam 11 and are used to synchronously drive the main crossbeam 11 to move in a first direction. By using the two first adjustment components to drive the two ends of the main crossbeam 11 to move synchronously in the first direction, it is ensured that the movement of the main crossbeam 11 can remain stable, and it can also provide support and anti-deflection effect for the main crossbeam 11 to a certain extent.

[0026] Further, please see Figure 3The first adjustment component includes a hydraulic cylinder 121 and a connecting shaft 122. The output end of the hydraulic cylinder 121 is connected to the connecting shaft 122 to drive the connecting shaft 122 to move in a first direction. The connecting shaft 122 is fixedly connected to the main crossbeam 11. When the hydraulic cylinder 121 is activated, its output end can extend or retract to drive the connecting shaft 122 to move in the first direction. The connecting shaft 122 then drives the main crossbeam 11 to move away from or closer to the leather in the first direction, thereby adjusting the position of the slitting roller 3. Because the hydraulic cylinder 121 has a large driving range and a rapid response, the slitting roller 3 can achieve rapid position adjustment under the drive of the hydraulic cylinder 121. In this embodiment, the hydraulic cylinder 121 is a hydraulic oil cylinder.

[0027] In some embodiments, see Figure 2 and Figure 3 The connecting shaft 122 includes a first fixed section 1221, a second fixed section 1222, and a threaded section 1223. The first fixed section 1221 and the second fixed section 1222 are connected by the threaded section 1223. Both the first fixed section 1221 and the second fixed section 1222 are fixedly connected to the main crossbeam 11. The end of the second fixed section 1222 away from the threaded section 1223 is connected to the hydraulic cylinder 121. By using the first fixed section 1221 and the second fixed section 1222 to be fixedly connected to the main crossbeam 11 respectively, when the hydraulic cylinder 121 drives the connecting shaft 122 to move in the first direction, the connecting shaft 122 can synchronously drive the main crossbeam 11 to move in the first direction. The main crossbeam 11 then drives the segmenting roller 3 to move, thereby realizing a wide-range and rapid drive of the segmenting roller 3 in the first direction.

[0028] In some embodiments, see Figure 4 The second adjustment mechanism 13 includes a second adjustment component, a third adjustment component, a drive component 131, and a transmission rod 132. The second and third adjustment components are respectively located at both ends of the main crossbeam 11. The drive component 131 is located at one end of the main crossbeam 11 and is drivenly connected to the second adjustment component to drive the second adjustment component to move in the first direction. Both ends of the transmission rod 132 are respectively drivenly connected to the second and third adjustment components to enable synchronous movement of the second and third adjustment components. By utilizing the drive component 131 to provide driving force, the driving force is transmitted to the second adjustment component to drive the main crossbeam 11 to move in the first direction. Simultaneously, when the second adjustment component is driven by the drive component 131, its movement is synchronously transmitted to the third adjustment component through the transmission rod 132, enabling the third adjustment component to drive the main crossbeam 11 to move in the first direction synchronously with the second adjustment component. This ensures the synchronous movement of the main crossbeam 11 as a whole and improves the stability of the main crossbeam 11 during movement.

[0029] It should be noted that the second and third adjustment components have the same structure; therefore, the specific structure and working principle of the third adjustment component will not be described in detail here. The following mainly describes the structure of the second adjustment component in detail: Please see Figure 4 The second adjusting assembly includes a worm gear 133, a turbine gear 134, a first bushing 135, and a second bushing 136. One end of the worm gear 133 is connected to the output end of the drive assembly 131, and the other end is connected to the transmission rod 132. The threaded portion of the worm gear 133 engages with the external thread of the turbine gear 134 to convert the rotation axis from the axial direction of the transmission rod 132 to the first direction. The turbine gear 134 is sleeved on the connecting shaft 122, and the internal thread of the turbine gear 134 engages with the threaded section 1223. The first bushing 135 and the second bushing 136 are respectively disposed at both ends of the turbine gear 134 along the first direction and are both fixedly connected to the main crossbeam 11. Specifically, when the drive assembly 131 is started, it drives the worm gear 133 to rotate. The worm gear 133 meshes with the turbine 134, causing the turbine 134 to rotate synchronously. Since the internal thread of the turbine 134 meshes with the threaded section 1223 of the connecting shaft 122, and since the connecting shaft 122 and the main crossbeam 11 are in a fixed connection state, that is, the connecting shaft 122 will not have relative movement or rotation with respect to the main crossbeam 11, the turbine 134 will rotate and move in the first direction at the same time under the action of the thread. The movement of the turbine 134 in the first direction will drive the first bushing 135 and the second bushing 136 to move, and then drive the main crossbeam 11 to move in the first direction, thereby realizing the fine adjustment of the position of the main crossbeam 11 in the first direction, and then realizing the fine adjustment of the position of the segmented roller 3 in the first direction.

[0030] In some embodiments, see Figure 4 The transmission rod 132 includes multiple transmission sub-rods 1321 and multiple couplings 1322. The multiple transmission sub-rods 1321 are connected sequentially through multiple couplings 1322, which can ensure the stable transmission of the transmission rod 132, enabling the two second adjustment components to move synchronously, and also avoid poor transmission effect due to the excessive length of the transmission rod 132 and its own deflection.

[0031] In some embodiments, the transmission rod 1321 is fitted with a bearing support 14, which is fixed to the inner wall of the main crossbeam 11. The bearing support 14 provides further support for the transmission rod 1321. The bearing connection ensures the synchronous rotation of the transmission rod 132 and can also basically eliminate the possibility of deformation of the transmission rod 1321 due to deflection and other problems.

[0032] In some embodiments, see Figure 4The drive assembly 131 includes a motor 1311 and a first gearbox 1312. The motor 1311 can be a servo motor or a stepper motor, without limitation. The first gearbox 1312 is a gearbox. The input end of the first gearbox 1312 is connected to the output end of the motor 1311 to reduce the rotational speed of the motor 1311. The output end of the first gearbox 1312 is connected to the worm gear 133 in the second adjustment assembly to transmit the reduced rotational speed to the worm gear 133. This avoids directly connecting the motor 1311 to the worm gear 133, which would cause the worm gear 133 to rotate too fast, making fine adjustment impossible and easily accelerating the damage of subsequent transmission components such as the worm gear 133, worm 134, and transmission rod 132. By using the motor 1311 and the first gearbox 1312 in cooperation, precise adjustment and control of the slitting roller 3 at the millimeter level can be achieved.

[0033] In some embodiments, see Figures 5 to 7 The slitting equipment also includes a local deformation device 2 for the slitting roller 3, which is used to locally deform the slitting roller 3. This local deformation device 2 includes multiple pressure compensation mechanisms 21. These multiple pressure compensation mechanisms 21 are sequentially spaced along the axial direction of the slitting roller 3 on the main crossbeam 11. The compensation ends of the multiple pressure compensation mechanisms 21 can move towards or away from the slitting roller 3 to increase or decrease the force exerted on the slitting roller 3 by the compensation ends, thereby causing different degrees of deformation at different positions of the slitting roller 3.

[0034] The technical solution provided by the embodiments of this application utilizes multiple pressure compensation mechanisms 21 to act on different positions of the slitting roller 3 to achieve deformation of the slitting roller 3. By utilizing the deformation of the slitting roller 3, the slitting roller 3 can change the degree of compression formed on different thickness positions of the leather, so as to adapt to the different thicknesses of the leather at different positions as much as possible and improve the uniformity of the leather after slitting.

[0035] For example, suppose the leather has uneven thickness, with the first part being 1cm thick, the second part 8mm thick, and the third part 4mm thick. In a traditional slitting device, the slitting roller 3 applies uniform pressure to the leather. Because the leather's thickness varies across different areas, even with consistent pressure from the slitting roller 3, the first part experiences significantly more pressure than the second and third parts, and vice versa. When the leather is pressed to a uniform thickness, slitting begins. The target slitting thickness is preset to 2mm. While the slitting blade does indeed slit to a 2mm thickness, the leather's elasticity means it will rebound based on the pressure applied during slitting. Due to varying degrees of rebound, the slitting results in a high probability that the first part will still be thicker than the second, and the second part will be thicker than the third, leading to a noticeable uneven thickness. For example, after the leather is split, the first part is 2mm, the second part is 2.3mm, and the third part is 2.6mm.

[0036] To address this issue, the slitting roller local deformation device 2 provided in this embodiment utilizes the compensation end of the pressure compensation mechanism 21 to squeeze or release different positions of the slitting roller 3, driving different positions of the slitting roller 3 to apply different degrees of compression to the leather. This solves the problem of thicker sections becoming even thicker due to springback. For example, by adjusting the compensation ends of multiple pressure compensation mechanisms 21 to move away from or closer to the slitting roller 3, the slitting roller 3 corresponding to the first part of the leather receives the maximum compensation force, the slitting roller 3 corresponding to the second part receives a medium compensation force, and the slitting roller 3 corresponding to the third part receives the minimum compensation force. This allows the leather section with greater springback to be compressed to a greater extent, further reducing the thickness of the thicker section during slitting, thereby compensating for the thickness increase caused by subsequent springback and improving the uniformity of the leather thickness after slitting.

[0037] In some embodiments, see Figure 7The pressure compensation mechanism 21 includes a drive pin 211, a lead screw 212, and a push rod 213. The lead screw 212 has external threads on its surface, and the push rod 213 is sleeve-shaped with internal threads on its inner wall that mesh with the external threads. The drive pin 211 is rotatably mounted inside the main crossbeam 11 and extends outside the main crossbeam 11. One end of the drive pin 211 inside the main crossbeam 11 is connected to the lead screw 212, and the end of the lead screw 212 away from the drive pin 211 is sleeved and threadedly engaged with the push rod 213, so that the push rod 213 moves towards or away from the segmented roller 3 along the axial direction of the lead screw 212, depending on the rotation direction of the drive pin 211. Workers can rotate the lead screw 212 by turning the drive pin 211. Since the lead screw 212 is in a fixed position, the internal and external threads allow the push rod 213 to move along the axial direction of the lead screw 212. Therefore, depending on the direction of turning the drive pin 211, the push rod 213 can be controlled to move towards or away from the segmenting roller 3, thus adjusting the pressure on the segmenting roller 3. It should be noted that the portion of the drive pin 211 located outside the main crossbeam 11 can be configured as a nut head, facilitating effortless turning using tools.

[0038] Further, please see Figure 7 The pressure compensation mechanism 21 also includes a steering box 214 and a second reduction gearbox 215. The input end of the steering box 214 is connected to the drive pin 211, and the output end is connected to the input end of the second reduction gearbox 215. The output end of the second reduction gearbox 215 is connected to the lead screw 212. Due to the limitations of the input and output positions of the second reduction gearbox 215, the steering box 214 is configured to accommodate the positions of the drive pin 211 and the second reduction gearbox 215. Specifically, the output end of the second reduction gearbox 215 is located at the bottom, and the inlet / outlet end is located on the side in the horizontal direction. Since the drive pin 211 is inserted into the main crossbeam 11 from the bottom, the steering box 214 is used to transfer the rotational motion of the drive pin 211 to the second reduction gearbox 215. The output end of the second reduction gearbox 215 is connected to the lead screw 212, thereby realizing the rotation of the lead screw 212. Furthermore, since the rotation of the active pin 211 is manually controlled, it is difficult to control the twisting amplitude at the millimeter or centimeter level. Therefore, by setting a second reduction gearbox 215, the rotation speed and amplitude of the lead screw 212 are effectively reduced, thereby enabling the push rod 213 to feed and retract with millimeter or centimeter precision.

[0039] In some embodiments, see Figure 7 The pressure compensation mechanism 21 also includes a scale 216, which is located at one end of the active pin 211 outside the main crossbeam 11. This allows the worker to observe the current rotation angle of the active pin 211 in real time, so that the worker can calculate the amount of rotation that meets the thickness requirements of the segmented leather based on their own experience, the reduction ratio of the second reduction gearbox 215, the pitch of the push rod 213, the leather rebound ability, etc.

[0040] In some embodiments, see Figure 5 and Figure 6 The partial deformation device 2 for the dividing roller also includes a secondary crossbeam 22. The secondary crossbeam 22 is located inside the main crossbeam 11 and extends along the axial direction of the dividing roller 3. The secondary crossbeam 22 is located between the top rod 213 and the dividing roller 3, so that the force of the top rod 213 is indirectly applied to the dividing roller 3 through the secondary crossbeam 22. By setting the secondary crossbeam 22 between the top rod 213 and the dividing roller 3, the force of the top rod 213 is indirectly transmitted to the dividing roller 3 through the secondary crossbeam 22. The large contact area of ​​the secondary crossbeam 22 with the dividing roller 3 effectively avoids point contact, that is, the top rod 213 directly contacts the dividing roller 3, which would cause the dividing roller 3 to be subjected to excessive pressure from the top rod 213 and leave marks.

[0041] Furthermore, the secondary crossbeam 22 is provided with multiple deformation auxiliary grooves 221 spaced apart along the axial direction of the segmenting roller 3. The deformation auxiliary grooves 221 are used to reduce the overall rigidity of the secondary crossbeam 22, so that the secondary crossbeam 22 can deform more easily while satisfying the surface contact with the segmenting roller 3. This makes it easier for workers to operate and also helps to reduce the risk of the secondary crossbeam 22 being punctured by the top rod 213 due to excessive rigidity.

[0042] In some embodiments, see Figure 5 and Figure 6 The partial deformation device 2 for the slitting roller also includes a support roller 23. The support roller 23 is located on the side of the secondary crossbeam 22 facing the slitting roller 3, and extends along the axial direction of the slitting roller 3, abutting against the slitting roller 3. By setting the support roller 23 between the secondary crossbeam 22 and the slitting roller 3, it is possible to prevent the slitting roller 3 from deforming in the vertical direction due to its own deflection, and also to prevent the slitting roller 3 from moving upward in the vertical direction. This restricts the vertical freedom of the slitting roller 3, allowing it to move only downward, i.e., in the direction of the leather, under the action of the top rod 213. In addition, since the support roller 23 is cylindrical and rotatable, it is equivalent to rolling friction between the support roller 23 and the slitting roller 3 when the slitting roller 3 is rotating. Compared with the sliding friction of direct contact with the secondary crossbeam 22, this is more conducive to the rotation of the slitting roller 3 and improves the smoothness of leather conveying.

[0043] Furthermore, the support roller 23 includes multiple support sub-rollers 231, which are spaced apart along the axial direction of the segmented roller 3. Each support sub-roller 231 is rotatably connected to the secondary crossbeam 22 to prevent deformation of the integral support roller 23 due to excessive length. Moreover, by using multiple support sub-rollers 231 to abut against the segmented roller 3, and by using multiple support sub-rollers 231 to achieve multi-position compression of the segmented roller 3, it is beneficial to avoid damage caused by frequent deformation of the excessively long support roller 23, and to drive the segmented roller 3 to deform more directly and accurately at corresponding positions.

[0044] In some embodiments, see Figure 5 and Figure 6 The first direction is the direction in which the compensation end of the pressure compensation mechanism 21 moves towards or away from the segmenting roller 3. The segmenting roller local deformation device 2 also includes a plurality of first limiting blocks 24 and a plurality of second limiting blocks 25 arranged sequentially along the axial direction of the segmenting roller 3. Along the radial direction of the segmenting roller 3 perpendicular to the first direction, the first limiting blocks 24 and the second limiting blocks 25 are respectively disposed on both sides of the segmenting roller 3 and abut against the segmenting roller 3. By using the first limiting blocks 24 and the second limiting blocks 25, the degree of freedom of the segmenting roller 3 in the radial direction perpendicular to the first direction is constrained, so that the segmenting roller 3 only has a degree of freedom in the vertical and downward direction, that is, the direction towards the leather, to ensure that the segmenting roller 3 will not tilt due to other reasons.
