[0002] Leather is animal hide that has undergone physical and chemical processing such as hair removal and tanning, resulting in a material that is no longer easily perishable. Therefore, leather is widely used in daily life. When using leather materials, it is necessary to cut the leather to obtain the appropriate size. Cutting is one of the important production processes in the leather processing industry. With the increasing demand for leather products, especially in the fields of footwear, bags, and automotive interiors.

[0003] When cutting leather, automatic feeding is usually required. However, some leather cutting and feeding devices are prone to deviation in the position of the leather during the feeding process, which affects the cutting accuracy and makes it difficult to limit the position of leather of different widths. Therefore, we propose a leather cutting and feeding device. Utility Model Content

[0018] This utility model has the following beneficial effects:

[0019] 1. This utility model, by setting rollers, allows for the following process when feeding leather: First, the leather is placed in front of the push plate. Then, the adjusting frame is pulled, causing the buckle groove on the adjusting frame to press against the locking block. The locking block slides under pressure inside the limiting groove, compressing the first spring. Simultaneously, the telescopic rod protects the first spring from deformation. At this point, the locking block slides out of the buckle groove and contacts the outer wall of the adjusting frame. The adjusting frame drives the locking pin to slide inside the first slide groove, adjusting the position of the roller. When it reaches the next buckle groove, the first spring rebounds, causing the locking block to engage with the buckle groove, limiting the adjusting frame. Then, the motor is started, driving the threaded block to move. The threaded block, along with the moving block, slides on the outer surface of the fixed rod, causing the push plate on the moving block to push the leather forward. The fixed rod limits the moving block, and the leather contacts the roller, achieving the effect of adjusting the position of the leather during feeding. This allows for adjustment of the position of leather of different widths to ensure the accuracy of subsequent leather cutting.

[0020] 2. This utility model, by setting a fixed plate, allows leather to be conveyed to the area below the cutting blade after feeding, so that the leather is placed on the spacer plate. The hydraulic rod moves downward, driving the cutting blade downward. At this time, the locking rod slides on the inner wall of the support frame, limiting the cutting blade. As the cutting blade moves downward, it also moves the fixed plate downward, and the second spring moves the fixed frame downward, fixing the leather. Then, the cutting blade continues to move downward, compressing the second spring. The sliding rod slides on the inner wall of the fixed plate, protecting the second spring. Subsequently, the cutting blade cuts the leather. When it is necessary to adjust the position of the spacer plate, the pull rod is pulled, causing the locking plate to compress the third spring. Then, the pull rod is pulled out from the positioning groove. At this time, the spacer plate is pushed, causing the slider to slide inside the second slide groove, limiting the spacer plate. Then, the pull rod is released, the third spring rebounds, and the pull rod quickly rebounds back into the positioning groove, fixing the spacer plate. This achieves the effect of fixing the leather during the cutting process, improving the cutting accuracy, and the position of the spacer plate can be adjusted to control the length of the cut leather.

Then, spacer plate 311 is pushed to adjust its position. Pull rod 314 is then released, sliding inside positioning groove 317, fixing spacer plate 311.

[0035] One specific application of this embodiment is:

[0036] When leather needs to be loaded, the leather is first placed in front of the push plate 208. Then, the adjusting frame 214 is pulled, causing the buckle groove 220 on the adjusting frame 214 to press against the locking block 219. The locking block 219 slides under pressure inside the limiting groove 216, compressing the first spring 218. While the first spring 218 is compressed, the telescopic rod 217 protects the first spring 218 to prevent deformation. At this time, the locking block 219 slides out of the buckle groove 220 and contacts the outer wall of the adjusting frame 214. The adjusting frame 214 drives the locking pin 212 to slide inside the slide groove 210, adjusting the position of the roller 213. When the leather reaches the next snap-fit ​​slot 220, the first spring 218 rebounds, causing the snap-fit ​​block 219 to engage inside the snap-fit ​​slot 220, limiting the adjustment frame 214. At this time, the start motor 203 drives the threaded block 206 to move. The threaded block 206, along with the moving block 207, slides on the outer surface of the fixed rod 209, causing the push plate 208 on the moving block 207 to push the leather forward. The fixed rod 209 limits the moving block 207. At this time, the leather contacts the roller 213, achieving the effect of adjusting the position of the leather during the feeding process. It can also adjust the position of leather of different widths to ensure the accuracy of subsequent leather cutting. The leather is fed to a position below the cutting blade 305, where it rests on the spacer plate 311. The hydraulic rod 303 moves downwards, causing the cutting blade 305 to move downwards as well. At this time, the locking rod 304 slides against the inner wall of the support frame 302, limiting the cutting blade 305. As the cutting blade 305 moves downwards, it also moves the fixing plate 306 downwards. The second spring 307 moves the fixing frame 308 downwards, securing the leather. The cutting blade 305 then continues to move downwards, compressing the second spring 307. The sliding rod 309 slides against the inner wall of the fixing plate 306, protecting the second spring 307. Finally, the cutting blade 305 cuts the leather... When the position of the spacer plate 311 needs to be adjusted during cutting, the pull rod 314 is pulled to compress the third spring 315 by the locking plate 316. Then, the pull rod 314 is pulled out from the positioning groove 317. At this time, the spacer plate 311 is pushed, so that the slider 312 slides inside the second slide groove 313, limiting the spacer plate 311. Then, the pull rod 314 is released, and the third spring 315 rebounds, so that the pull rod 314 quickly rebounds into the positioning groove 317 to fix the spacer plate 311. This achieves the effect of fixing the leather during the cutting process, improving the cutting accuracy, and the position of the spacer plate 311 can be adjusted to control the length of the cut leather.
