Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-4The present invention provides a leather cutting machine, including a support plate 101 for placing a leather body 103, support legs 102 fixedly installed at the four corners of the bottom of the support plate 101, a movable frame 2 slidably connected to the support plate 101, a driving component for assisting the movement of the movable frame 2 on the support plate 101, and a U-shaped platform 3 disposed inside the movable frame 2. A driving component for driving the U-shaped platform 3 is disposed on the movable frame 2. A U-shaped frame 5 is disposed below the U-shaped platform 3. A lifting component for raising and lowering the U-shaped frame 5 is disposed on the U-shaped platform 3. A connecting block 7 is disposed on the inner side of the U-shaped frame 5. A telescopic component for telescopically connecting the connecting block 7 is disposed on the U-shaped frame 5. A cutting component for cutting the leather body 103 is disposed on the connecting block 7. An identification component for distance identification of the cutting component during the cutting process is disposed on the inner side of the U-shaped frame 5.
[0020] It should be noted that the cooperation of the drive component, lifting component, telescopic component, identification component and cutting component effectively prevents the leather edge from being scorched, wrinkled or delaminated due to excessive pressure of the blade 802 on the leather body 103, thus ensuring the quality and appearance of the leather.
[0021] It is worth noting here that the drive component mentioned above for assisting the movement of the mobile frame 2 is a conventional drive component for movement drive, and is considered prior art in this application. Its working principle and operation method will not be further described here.
[0022] The cutting assembly includes a blade holder 801 fixedly connected to the lower part of the connecting block 7, and a blade 802 is mounted on the blade holder 801;
[0023] It should be noted here that the leather body 103 is cut using blade 802.
[0024] Two sets of telescopic components are symmetrically arranged between the U-shaped frame 5 and the connecting block 7. The telescopic components include multiple sets of sleeves 901 fixedly connected to the inner side of the U-shaped frame 5. A second slide rod 902 is slidably connected to the sleeve 901. One end of the second slide rod 902 is fixedly connected to the connecting block 7. A spring 903 is sleeved on the outer side of the sleeve 901.
[0025] It should be noted here that the connecting block 7 is telescopically connected by multiple sets of sleeves 901 and the second slide rod 902, and the connecting block 7 is reset by the elastic force of the spring 903.
[0026] There are two sets of identification components, and the two sets of identification components are evenly distributed on both sides of the connecting block 7. The identification component is a proximity sensor 10 installed on the U-shaped frame 5 for identifying the extension distance of the connecting block 7. An alarm is installed on the U-shaped frame 5 to trigger an alarm when the distance identification is abnormal.
[0027] It should be noted here that the extension distance of the connecting block 7 is identified by the proximity sensor 10, and the alarm is triggered when the proximity sensor 10 detects an abnormality in the distance.
[0028] It should also be noted here that: a controller is installed on the U-shaped frame 5, and the alarm and the controller are electrically connected. Through the cooperation of the proximity sensor 10, the controller and the alarm, the distance identification control and alarm are realized. The proximity sensor 10, the controller and the alarm are considered prior art in this application, and their working principle and operation method will not be further described here.
[0029] The drive assembly includes two sets of first slide rods 401 symmetrically slidably connected to the U-shaped platform 3. The two sets of first slide rods 401 are fixed to the movable frame 2. A threaded tube 402 is fixedly installed on the U-shaped platform 3. A threaded rod 403 is threadedly engaged on the threaded tube 402. The threaded rod 403 is rotatably connected to the movable frame 2. A motor 404 that drives the threaded rod 403 is installed on one side of the movable frame 2.
[0030] It should be noted here that: the drive motor 404 drives the threaded rod 403 to rotate, and through the threaded engagement between the threaded rod 403 and the threaded tube 402, the U-shaped platform 3 moves on the first slide rod 401.
[0031] The lifting component is a cylinder 6 installed on the U-shaped platform 3, and the output end of the cylinder 6 is fixedly connected to the U-shaped frame 5.
[0032] It should be noted here that the U-shaped frame 5 is raised and lowered by cylinder 6.
[0033] Working principle: During the process of cutting the leather body 103 using the leather cutting machine, the leather body 103 is first laid on the support plate 101, and then the position of the moving frame 2 is adjusted by the drive component;
[0034] After the position of the movable frame 2 is adjusted, the U-shaped frame 5 is lowered by the lifting component. The lowering of the U-shaped frame 5 drives the blade 802 to descend, so that the blade 802 is inserted under the leather body 103.
[0035] When the blade 802 descends to the appropriate position, the drive motor 404 drives the threaded rod 403 to rotate. Through the threaded engagement between the threaded rod 403 and the threaded tube 402, the U-shaped table 3 moves on the first slide rod 401. Through the movement of the U-shaped table 3, the U-shaped frame 5 moves. Through the movement of the U-shaped frame 5, the cutting assembly moves.
[0036] During the movement of the cutting component, the blade 802 cuts the leather body 103. When the cutting speed of the blade 802 is too fast, the pressure of the blade 802 on the cutting edge of the leather body 103 will increase rapidly. When the pressure of the blade 802 on the cutting edge of the leather body 103 increases, the connecting block 7 will move towards the inner wall of the U-shaped frame 5. At this time, the proximity sensor 10 will sense the displacement of the connecting block 7. When the displacement distance exceeds the set maximum value, the alarm installed on the U-shaped frame 5 for distance identification abnormality alarm will sound an alarm, reminding the operator to reduce the moving speed of the cutting component to prevent the leather edge from being scorched, wrinkled, or delaminated due to excessive pressure of the blade 802 on the leather body 103, thus ensuring the quality and appearance of the leather.
[0037] 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. No reference numerals in the claims should be construed as limiting the scope of the claims.
