By suspending a cutter holder for cutting fabric at the bottom of the pressing device, when cutting the shoe upper fabric, the shoe upper fabric is placed on the movable push plate located below the pressing device, and the pressing device moves downward, causing the cutter holder to fall onto the shoe upper fabric. The cutter holder is then pressed down, thus completing the cutting of the shoe upper fabric. Compared with the prior art, manual cutting of the shoe upper fabric is eliminated, improving the cutting efficiency of the fabric, and ensuring that the effect of each cut is consistent, allowing the subsequent shoe manufacturing process to proceed smoothly.

[0003] The aforementioned blade holder is fixedly mounted on the pressure plate and cannot be directly disassembled, making it difficult to replace the blade. In addition, the cut shoe upper material is prone to getting stuck on the inside of the blade, making it inconvenient to cut the shoe upper material. Utility Model Content

A horizontal column slidably connected between the first support column and the second support column is fixedly fitted on the outer side of the bottom end of the cylinder. A symmetrically distributed slide rail is fixedly installed on the top of the machine base. A first slide seat and a second slide seat are slidably connected on the outer side of the slide rail. A fixing rod is provided on the top of both the first slide seat and the second slide seat. A support plate located directly below the horizontal column is movably sleeved on the outer side of the top of the fixing rod. A retaining ring is engaged on the outer side of the top of the fixing rod extending outside the support plate. A first spring located below the support plate is fitted on the outer side of the fixing rod. A knife holder is placed on the inner side of the support plate, and a cutting knife is provided at the bottom of the knife holder.

[0005] The first and second support columns each have a limiting mechanism installed inside, with one end respectively fitted inside the first and second slides. A pressure plate is fixedly installed at the bottom of the horizontal column. The outer side of the tool holder has symmetrically distributed limiting bosses located above the support plate. A positioning post located on the top of the support plate is movably sleeved inside the limiting boss. A clearance hole is opened inside the tool holder. A feeding rod with its top end movably sleeved inside the horizontal column is movably fitted inside the pressure plate.

[0006] Preferably, the horizontal column is internally fitted with a third spring located above the feed rod.

[0007] Preferably, both the first slide and the second slide have symmetrically distributed inclined surfaces on one side.

[0008] Preferably, the inner diameter of the clearance hole is larger than the outer diameter of the feed rod.

[0009] Preferably, the limiting mechanism includes a pull rod with one end movably sleeved inside the first support column and the second support column and the other end movably sleeved inside the first slide block and the second slide block. An annular boss is provided on the outer side of one end of the pull rod, which is movably sleeved inside the first support column and the second support column. A second spring is sleeved on the outer side of the pull rod, located on one side of the annular boss and sleeved inside the first support column and the second support column. A pull ring is fixedly sleeved on the outer side of the end of the pull rod that extends outside the first support column and the second support column.

[0010] This utility model has the following beneficial effects:

[0011] 1. The shoe upper fabric cutting device can pull the pull rod out from the inside of the first slide and the second slide through the pull ring, and at the same time release the limit on the first slide and the second slide, so that the support plate can be moved away from the bottom of the pressure plate. Furthermore, through the cooperation of the limiting boss and the positioning post, the cutter holder can be directly disassembled and installed from the top of the support plate, so as to facilitate the replacement of the cutter.

[0012] 2. The shoe upper fabric cutting device can avoid the material feeding rod through the avoidance hole, so that during the cutting process, the material feeding rod can press the shoe upper fabric at the cutting part. After the device completes the cutting of the shoe upper fabric, the material feeding rod can push the cut shoe upper fabric out from the inside of the cutter under the elastic force of the third spring, thereby ensuring that the cut shoe upper fabric will not be stuck on the inside of the cutter, thus facilitating the cutting of the shoe upper fabric.

[0019] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0020] The accompanying drawings in this utility model embodiment: different types of cross-sectional lines in the drawings are not labeled according to national standards, nor do they specify the material requirements of the components. They are used to distinguish the cross-sectional views of the components in the drawings.

[0021] Please see Figure 1-4A shoe upper fabric cutting device includes a machine base 1, a first support column 2 and a second support column 3 fixedly installed on the top of the machine base 1, and a cylinder 5 fixedly installed between the first support column 2 and the second support column 3 via a crossbeam 4. A horizontal column 6 slidably connected between the first support column 2 and the second support column 3 is fixedly fitted onto the outer side of the bottom end of the cylinder 5. A symmetrically distributed slide rail 7 is fixedly installed on the top of the machine base 1. A first slide block 8 and a second slide block 9 are slidably connected to the outer side of the slide rail 7. Through the cooperation of the slide rail 7, the first slide block 8, and the second slide block 9, a support plate 11 can slide along the outer side of the slide rail 7, facilitating manual removal of the support plate 11 from under the pressure plate 17, and making it convenient to cut the upper fabric on the support plate 11. The blade holder 14 is disassembled and replaced. The top of the first slide 8 and the second slide 9 are both equipped with a fixing rod 10. The outer side of the top of the fixing rod 10 is movably sleeved with a support plate 11 located directly below the horizontal column 6. The outer side of the top of the fixing rod 10 extending out of the support plate 11 is engaged with a retaining ring 12. The outer side of the fixing rod 10 is fitted with a first spring 13 located below the support plate 11. The elastic force of the first spring 13 can drive the support plate 11 to move upward along the axis of the fixing rod 10. Thus, the cutter 15 can automatically reset after cutting the shoe upper fabric, so as to facilitate the position adjustment of the uncut shoe upper fabric. The blade holder 14 is placed inside the support plate 11, and the cutter 15 is provided at the bottom of the blade holder 14.

[0022] The first support column 2 and the second support column 3 are each equipped with a limiting mechanism 16, one end of which is respectively fitted inside the first slide 8 and the second slide 9. The bottom of the horizontal column 6 is fixedly installed with a pressure plate 17. When the horizontal column 6 moves downward under the drive of the cylinder 5, the pressure plate 17 can press the cutter holder 14, thereby cutting the shoe upper material through the cutter 15 on the cutter holder 14. The outer side of the cutter holder 14 is provided with symmetrically distributed limiting bosses 18 located above the support plate 11. The limiting bosses 18 are movably sleeved with a positioning post 19 set on the top of the support plate 11. Through the cooperation of the limiting bosses 18 and the positioning post 19, the cutter holder 14 can be positioned, and the cutter holder 14 can be limited and supported by the support plate 11. The cutter holder 14 is provided with a clearance hole 20. The pressure plate 17 is movably sleeved with a feeding rod 21 whose top end is movably sleeved inside the horizontal column 6.

[0023] The internal part of the horizontal column 6 is fitted with a third spring 22 located above the feed rod 21. The elastic force of the third spring 22 can drive the feed rod 21 to move downward, while making it easier to push the cut shoe upper fabric out from the inside of the cutter 15, thereby preventing the shoe upper fabric from getting stuck on the inside of the cutter 15.

[0024] The first slide 8 and the second slide 9 each have symmetrically distributed inclined surfaces on one side. The inclined surfaces can avoid the pull rod 161 while allowing the first slide 8 and the second slide 9 to push the pull rod 161 during movement, thus facilitating the automatic insertion of the pull rod 161 into the interior of the first slide 8 and the second slide 9.

[0025] The inner diameter of the clearance hole 20 is larger than the outer diameter of the feed rod 21. This structure ensures that the feed rod 21 will not interfere with the tool holder 14 during its movement.

[0026] The limiting mechanism 16 includes a pull rod 161, one end of which is movably sleeved inside the first support column 2 and the second support column 3, and the other end of which is movably sleeved inside the first slide block 8 and the second slide block 9. The pull rod 161 can limit and fix the first slide block 8 and the second slide block 9 to ensure that the support plate 11 will not move during the cutting operation of the shoe upper fabric. An annular boss 162 is provided on the outer side of one end of the pull rod 161, which is movably sleeved inside the first support column 2 and the second support column 3. A second spring 163 is sleeved on the outer side of the pull rod 161, located on one side of the annular boss 162 and sleeved inside the first support column 2 and the second support column 3. The elastic force of the second spring 163 can automatically lock the pull rod 161 into the interior of the first slide block 8 and the second slide block 9 through the annular boss 162. A pull ring 164 is fixedly sleeved on the outer side of the end of the pull rod 161 that extends outside the first support column 2 and the second support column 3. The pull ring 164 can limit the pull rod 161 and facilitate the pulling of the pull rod 161.

[0027] When replacing the cutter 15, pulling the pull rod 161 via the pull ring 164 compresses the second spring 163 through the annular boss 162. Once the pull rod 161 moves out of the first slide block 8 and the second slide block 9, the limiting effect on the first slide block 8 and the second slide block 9 is released. At this point, the support plate 11 is pulled away from under the pressure plate 17, and the pull ring 164 is released. The elastic force of the second spring 163 drives the pull rod 161 to reset. After manually disassembling each cutter holder 14 one by one from above the support plate 11, the cutter holder 14 to be replaced is... The cutter 15 is installed one by one on the support plate 11 through the cooperation of the limiting boss 18 and the positioning post 19. After all the cutter holders 14 are replaced, the support plate 11 is pushed under the pressure plate 17. During this process, the pull rod 161 is pushed by the inclined surfaces on the first slide 8 and the second slide 9. When the support plate 11 is moved to the direct under the pressure plate 17, the pull rod 161 is fully inserted into the interior of the first slide 8 and the second slide 9 by the force of the second spring 163, thus completing the replacement of the cutter 15.
