In a broader sense, leather goods also include leather clothing, leather shoes, and other leather products.
[0003] Leather cutting machines are needed when processing raw materials for leather goods. There are many different types of leather cutting machines. Generally, leather cutting machines use electric saws to cut leather. Among them, the leather cutting machine is one type of leather cutting machine. The leather cutting machine lays the leather on a platform and uses blades to cut different shapes of leather from the leather. Nowadays, the blades on leather cutting machines are replaced by laser cutting.
[0004] When using a leather cutting machine, the leather needs to be placed. The leather is easily affected by wrinkles during cutting, which can cause large deviations in the shape of the cut leather. This can affect the cutting accuracy of the leather cutting machine and reduce the yield of the cut products. Therefore, this utility model proposes a fully automatic leather cutting machine that can stretch and position the leather after cutting. Utility Model Content

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0026] Please see Figure 1-4 An embodiment of this utility model is provided: a fully automatic leather cutting machine, including a base 1 and a cutting table 2 provided on the base 1;
[0027] Please refer to the instruction manual for details. Figure 2 as well as Figure 4 As shown, two guide plates 12 are fixedly installed on both sides of the upper surface of the cutting table 2. A first positive and negative screw 13 is rotatably installed inside one of the guide plates 12 through a bearing. A second guide rod 14 is fixedly installed inside the other guide plate 12. Two symmetrically distributed clamping frames 16 are arranged between the first positive and negative screw 13 and the second guide rod 14. One end of the two clamping frames 16 is threadedly connected to the positive and negative threaded parts of the first positive and negative screw 13, and the other end of the two clamping frames 16 is slidably connected to the second guide rod 14.
[0028] With this structural design, when the No. 1 forward and reverse screw 13 is rotating, the two clamping frames 16 connected by the forward and reverse threads will move relative to each other, that is, move away from each other or move closer to each other. This effect depends on the forward and reverse rotation of the No. 1 forward and reverse screw 13.
[0029] The two clamping frames 16 are each mounted with a No. 2 positive and negative screw 17 through bearings. The positive and negative threads of the two No. 2 positive and negative screws 17 are each threaded with a threaded block 19. The lower surface of the threaded block 19 is fixedly mounted with a clamping cylinder 20. The output end of the clamping cylinder 20 is movably connected to a pneumatic rod. The bottom end of the pneumatic rod is fixedly mounted with a clamping plate 21.
[0030] Based on the above structure, this utility model uses a clamping cylinder 20 to drive a pneumatic rod to extend and retract. When the pneumatic rod extends, it drives the clamping disc 21 at the bottom to descend. In this way, the four clamping discs 21 descend and pneumatically press the leather below, achieving four-point positioning and clamping. This effectively presses and positions the leather, preventing it from moving during cutting and improving cutting accuracy.
[0031] Meanwhile, in actual operation, the leather can be pulled to the bottom of the four-point clamping plate 21 by manual tensioning. The four clamping plates 21 can then position and clamp the tensioned leather, which can effectively prevent the leather from wrinkling due to springback during cutting. This can effectively reduce the dimensional deviation during leather cutting, improve the accuracy of leather cutting, and has a good practical effect.
[0032] This utility model can be rotated by the No. 2 positive and negative screw 17. When the No. 2 positive and negative screw 17 is rotating, the two threaded blocks 19 connected by threads on it will move relative to each other. In this way, the relative movement of the threaded blocks 19 can drive the clamping cylinder 20 and the clamping plate 21 below to move relative to each other, thereby adjusting the distance between the two clamping plates 21.
[0033] This structural design, by adjusting the distance between the two clamping discs 21, can be applied to the positioning and clamping of leathers of different widths. The distance can be dynamically adjusted according to the square leathers of different widths, thereby effectively improving the applicable range of leather widths of this utility model.
[0034] When the first positive and negative screw 13 rotates, the two clamping frames 16 connected by its threads will move relative to each other, that is, move away from each other or move closer to each other. In this way, the two clamping frames 16 can drive the two sets of clamping discs 21 on the same side to move relative to each other. Under the action of the clamping frames 16, the two sets of clamping discs 21 on the same side can move relative to each other in the length direction. Thus, the distance between the two clamping discs 21 can be adjusted by the relative movement of the clamping frames 16. In actual use, it can be used for positioning and clamping leather of different lengths.
[0035] This utility model utilizes the threaded transmission effect of two positive and negative screws to drive several clamping discs 21 to adjust their distance and position in the front-back and left-right directions. This allows it to be used for cutting and positioning square leather materials of different lengths and widths, thus broadening its dimensional applicability. It can be dynamically adjusted according to different square leather sizes, making it more practical and effectively reducing the limitations of its use, resulting in better practical performance.
[0036] In this embodiment, in order to drive the No. 1 positive and negative screw 13 and the No. 2 positive and negative screw 17 to perform automated rotation, one end of the No. 1 positive and negative screw 13 is fixedly connected to the output shaft of the No. 3 motor 15, and the No. 3 motor 15 is fixedly installed on the outer wall of the No. 2 guide plate 12 by bolts.
[0037] Furthermore, one end of each of the two No. 2 positive and negative screws 17 is fixedly connected to the output shaft of the No. 4 motor 18, which is fixedly mounted on the side wall of the clamping frame 16 by bolts.
[0038] Thus, the No. 3 motor 15 and the No. 4 motor 18 can drive the No. 1 screw 13 and the No. 2 screw 17 to perform automated forward and reverse rotation.
[0039] In this embodiment, in order to ensure the normal cutting operation of the cutting machine of this utility model, a first guide plate 3 is fixedly installed on the outer side of the two second guide plates 12 and on the upper surface of the cutting table 2. A first screw 4 is rotatably installed inside one of the first guide plates 3 through a bearing, and a first guide rod 5 is fixedly installed inside the other first guide plate 3.
[0040] Furthermore, a cutting frame 6 is provided between the first screw 4 and the first guide rod 5. One side of the cutting frame 6 is threadedly connected to the first screw 4, and the other side of the cutting frame 6 is slidably connected to the first guide rod 5.
[0041] Furthermore, a second screw 8 is rotatably mounted inside the cutting frame 6 via a bearing. A threaded female seat 9 is threadedly connected to the second screw 8, and a laser cutter 10 is fixedly mounted on the outer wall of the threaded female seat 9.
[0042] According to the above description, the present invention can complete the laser cutting of the leather material below by means of the laser cutter 10.
[0043] The present invention features a rotating second screw 8. When the second screw 8 rotates, the threaded female seat 9 connected to it can move left and right along the second screw 8. The movement of the threaded female seat 9 can drive the laser cutter 10 to move, thereby satisfying the requirement for the laser cutter 10 to move freely in the X-axis.
[0044] When the first screw 4 is rotating, the cutting frame 6 connected to it by the thread can move back and forth along the first screw 4. In this way, the back and forth movement of the cutting frame 6 can drive the laser cutter 10 to move back and forth synchronously, thereby satisfying the free movement effect of the laser cutter 10 in the Y-axis.
[0045] By freely moving the laser cutter 10 along the X and Y axes, the laser cutting area can be transformed into a free region on a two-dimensional plane, satisfying the normal displacement effect of the laser cutter 10 and ensuring normal use.
[0046] In this embodiment, in order to drive the No. 1 screw 4 and the No. 2 screw 8 to perform automated rotation, one end of the No. 1 screw 4 is fixedly connected to the output shaft of the No. 1 motor 7, and the No. 1 motor 7 is fixedly installed on the outer wall of the corresponding No. 1 guide plate 3.
[0047] Furthermore, one end of the second screw 8 is fixedly connected to the output shaft of the second motor 11, and the second motor 11 is fixedly installed on the outer wall of the cutting frame 6.
[0048] Working principle: When using this utility model, the square leather piece that needs to be cut can be placed on the cutting table 2 of this utility model and stretched so that the four points of the square leather piece are respectively placed under the four clamping plates 21. The stretched leather piece will not have wrinkles, thereby improving the dimensional accuracy of subsequent cutting.
[0049] After the four corners of the leather are stretched, the clamping cylinder 20 starts working. The clamping cylinder 20 drives the air rod to extend and retract. When the air rod extends, it drives the clamping plate 21 at the bottom to descend. The four clamping plates 21 descend and pneumatically press the leather below, thus achieving four-point positioning and clamping. This can press and position the leather to prevent it from moving during cutting and improve the accuracy of cutting.
[0050] Meanwhile, the four clamping discs 21 position and clamp the tightened leather, which can effectively prevent the leather from wrinkling due to springback during cutting. This can effectively reduce the dimensional deviation during leather cutting, improve the accuracy of leather cutting, and have a good practical effect.
[0051] After the four corners of the leather are stretched and positioned, the laser cutter 10 can then be used to cut the leather material below.
[0052] The second screw 8 of this utility model can rotate under the action of the second motor 11. When the second screw 8 rotates, the threaded female seat 9 connected to it can move left and right along the second screw 8. Thus, the movement of the threaded female seat 9 can drive the laser cutter 10 to move, thereby satisfying the free movement effect of the laser cutter 10 in the X-axis.
[0053] When the No. 1 screw 4 rotates under the drive of the No. 1 motor 7, the cutting frame 6 connected to the screw 4 can move back and forth along the No. 1 screw 4. In this way, the back and forth movement of the cutting frame 6 can drive the laser cutter 10 to move back and forth synchronously, thereby satisfying the free movement effect of the laser cutter 10 in the Y-axis.
[0054] By freely moving the X and Y axes of the laser cutter 10, the laser cutting area can be transformed into a free area on a two-dimensional plane, satisfying the normal displacement effect of the laser cutter 10 and ensuring normal use.
[0055] The present invention can rotate under the drive of the No. 4 motor 18 by setting the No. 2 positive and negative screw 17. When the No. 2 positive and negative screw 17 rotates, the two threaded blocks 19 connected by threads on it will move relative to each other. In this way, the relative movement of the threaded blocks 19 can drive the clamping cylinder 20 and the clamping plate 21 below to move relative to each other, thereby adjusting the distance between the two clamping plates 21 on the same side.
[0056] This structural design, by adjusting the distance between the two clamping discs 21, can be applied to the positioning and clamping of leathers of different widths. The distance can be dynamically adjusted according to the square leathers of different widths, thereby effectively improving the applicable range of leather widths of this utility model.
[0057] When the No. 1 forward and reverse screw 13 rotates under the action of the No. 3 motor 15, the two clamping frames 16 connected by threads on it will move relative to each other, that is, move away from each other or move closer to each other. In this way, the two clamping frames 16 can drive the two sets of clamping discs 21 on the same side to move relative to each other. Under the action of the clamping frames 16, the two sets of clamping discs 21 on the same side can move relative to each other in the length direction. Thus, the distance between the two clamping discs 21 can be adjusted by the relative movement of the clamping frames 16. In actual use, it can be used for positioning and clamping leather of different lengths.
[0058] This utility model utilizes the threaded transmission effect of two positive and negative screws to drive several clamping discs 21 to adjust their distance and position in the front-back and left-right directions. This allows it to be used for cutting and positioning square leather materials of different lengths and widths, thus broadening its dimensional applicability. It can be dynamically adjusted according to different square leather sizes, making it more practical and effectively reducing the limitations of its use, resulting in better practical performance.
[0059] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
