[0002] The shoe machinery industry is a strong support for the development of China's shoe industry. Thanks to the improvement of product quality awareness in China's shoe industry, the shoe machinery industry has also risen with the tide and made great progress. my country's shoe machinery has basically covered all aspects of the shoe manufacturing process, and the design and manufacturing capabilities of some enterprises have reached the international leading level. In shoe manufacturing, cutting machines are needed to cut the shoe fabric.

[0003] Cutting machines are indispensable equipment in some light industries. They are machines that use the force of machine movement to press on a die to punch non-metallic materials. In shoe production, shoe soles need to be produced. The shoe sole is cut by the cutting die on the cutting machine.

[0004] Compared to traditional shoe-making cutting machines, existing cutting machines can fix the fabric during cutting, avoiding wrinkles that could lead to substandard cuts and unnecessary waste. However, cutting generates fabric debris and dust, which, if not cleaned up, can easily escape into the air and be inhaled by workers, affecting their health. Furthermore, after cutting, fabric fragments tend to accumulate on the processing platform, impacting processing accuracy and product quality. Therefore, a vertical cutting machine is proposed that allows for rapid loading and unloading, and can clean up debris and dust, as well as collect the fabric. Utility Model Content

[0013] Compared with existing technologies, the advantages of this invention are as follows: During cutting, the intermittent conveyor belt stops conveying, and the telescopic rod drives the fixed plate and die-cutting blade to press down on the fabric to cut it. At the same time, the fixed plate exerts a downward force on the movable cover plate, which is pressed down under the action of the elastic component until the movable cover plate contacts the intermittent conveyor belt and forms a sealed space with the side plate of the U-shaped support frame, preventing the escape of debris and dust during cutting. At the same time, the air pump is activated, allowing the dust suction pipe to suck up the dust inside the sealed space. Then, the telescopic rod moves upward, and the movable cover plate moves upward under the rebound of the spring. The intermittent conveyor belt continues to convey, preventing dust from escaping into the air. Fabric debris generated during cutting can be collected uniformly. The intermittent conveyor belt feeds and discharges quickly, resulting in high cutting efficiency. Attached Figure Description

[0022] Furthermore, some of the aforementioned terms, besides indicating location or positional relationships, may also have other meanings. For example, the term "above" may, in certain circumstances, indicate a dependency or connection. Those skilled in the art can understand the specific meaning of these terms in this utility model based on the specific circumstances. Additionally, the term "multiple" should mean two or more.

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments of the present invention can be combined with each other. The following will refer to the accompanying drawings. Figures 1-4 The present invention will be described in detail with reference to the embodiments.

[0024] A vertical cutting machine includes a workbench 1, on which an intermittent conveyor belt 2 is rotatably mounted. The intermittent conveyor belt 2 is rotatably mounted on the table of the workbench 1 and can be connected to the feeding and unloading conveyor of shoe sole fabric to achieve seamless program connection. The fabric is intermittently conveyed, the conveyor stops when cutting, and the conveyor resumes after cutting. The conveying interval time is preset.

[0025] An observation window 26, preferably made of tempered glass, is provided on the front side wall of the workbench 1. The observation window 26 allows observation of the internal cutting process. A U-shaped support frame 3 is fixedly installed on the tabletop of the workbench 1. A hydraulic cylinder 16 is installed on the top wall of the U-shaped support frame 3. The top of the telescopic rod 7 passes through the top wall of the U-shaped support frame 3 and is located at the output end of the hydraulic cylinder 16. Activating the hydraulic cylinder 16 allows the telescopic rod 7 to move up and down.

[0026] A cutting unit 8 is provided at the bottom of the telescopic rod 7. The cutting unit 8 includes a fixed plate 9 and a die-cutting blade 10 connected to each other. The die-cutting blade 10 can pass through the through hole 6, and the fixed plate 9 can press down the movable cover plate 4. When the telescopic rod 7 moves downward, it also moves the fixed plate 9 downward. Since a connecting rod 24 is integrally formed at the center of the bottom wall of the fixed plate 9, and the die-cutting blade 10 is detachably mounted at the bottom end of the connecting rod 24 via a bolt assembly, the die-cutting blade 10 also moves downward, passing through the through hole 6 to cut the fabric below.

[0027] The vertical height from the bottom wall of the fixed plate 9 to the bottom of the die-cutting blade 10 is the same as the vertical height from the top wall of the movable cover plate 4 to the intermittent conveyor belt 2 when the elastic component 5 is compressed. This ensures that when the fixed plate 9 drives the movable cover plate 4 to press down to its limit, the bottom of the die-cutting blade 10 can just cut the fabric and then make no force contact with the intermittent conveyor belt.

[0028] The through hole 6 is provided through the top cover plate 19. Both the fixing plate 9 and the through hole 6 are preferably circular structures, and the circular cross-sectional area of ​​the fixing plate 9 is larger than that of the through hole 6. Therefore, the through hole 6 can intercept the fixing plate 9 above the top cover plate 19. When the fixing plate 9 is pressed down, it can drive the top cover plate 19 to move downward, thereby driving the entire movable cover plate 4 to move downward.

[0029] The bottom wall of the fixed plate 9 is provided with several limiting grooves 17, and the top wall of the top cover plate 19 is provided with several limiting protrusions 18. The number of limiting grooves 17 and limiting protrusions 18 are the same and they are mutually compatible. This allows the fixed plate 9 and the movable cover plate 4 to be fixed to each other, enhancing stability and preventing movement or shaking during cutting, which would affect the cutting accuracy.

[0030] The U-shaped support frame 3 has a movable cover plate 4 inside. The movable cover plate 4 is preferably U-shaped and includes two side plates 23 and a top cover plate 19. The two side plates 23 are perpendicular to the side walls of the U-shaped support frame 3. The bottom and top of the movable cover plate 4 are respectively provided with elastic components 5 and through holes 6. The bottom end of the movable cover plate 4 is in movable contact with the intermittent conveyor belt 2.

[0031] The elastic component 5 includes a slide groove 20, a fixed post 21, and a spring 22. Two slide grooves 20 are respectively provided on the bottom wall of the side plates 23 on both sides. The fixed post 21 is movably arranged inside the slide groove 20, and the spring 22 is movably sleeved on the outer wall of the fixed post 21. The size of the spring 22 is larger than the size of the slide groove 20.

[0032] The fixed plate 9 is pressed down, causing the movable cover plate 4 to move down, so that the side plate 23 slides down along the slide 20. The spring 22 is compressed by pressure until the fixed column 21 contacts the top wall of the slide 20, and the bottom walls of the two side plates 23 contact the top of the intermittent conveyor belt 2. At the same time, the die-cutting knife 10 cuts the fabric.

[0033] After the fabric is cut, the fixed plate 9 moves upward under the action of the telescopic rod 7, and the movable cover plate 4 also moves upward under the restoring action of the spring, until the side plate 23 moves away from the surface of the intermittent conveyor belt 2, so that it can resume conveying materials.

[0034] The top wall of the movable cover plate 4 is also provided with ventilation holes 29, which can exchange air with the outside and ensure stable internal and external air pressure when the internal air is extracted. The bottom of the workbench 1 is provided with a partition 13, and a collection box 14 is embedded in the partition 13, which can be used to collect fabric scraps and debris generated during cutting.

[0035] The air pump 12 is fixedly installed on the outer wall of the collection box 14 opposite to the suction pipe 11. The collection box 14 is equipped with a filter screen 27. The side walls of the collection box 14 on both sides of the filter screen 27 are respectively provided with air inlets 28. One air inlet 28 is connected to the bottom end of the suction pipe 11, and the other air inlet 28 is connected to the air inlet of the air pump 12. A covered discharge port 15 is provided through the bottom wall of the collection box 14. The internal space of the movable cover plate 4 after being pressed down is connected to the collection box 14 through the suction pipe 11 and the air pump 12.

[0036] The bottom end of the suction pipe 11 is connected to the collection box 14, and the top end of the suction pipe 11 passes through the side wall of the U-shaped support frame 3 and is located inside the movable cover plate 4. A suction hood 25 is provided at the top end of the suction pipe 11, and the suction hood 25 is directly above the intermittent conveyor belt 2.

[0037] Tighten the cover of the discharge port 15, start the air pump 12, and generate suction through the two air inlets 28 of the collection box 14 and the suction pipe 11, so that the dust hood 25 can suck the debris and dust generated during cutting into the suction pipe 11, and then enter the collection box 14 through the air inlet 28. After the debris and impurities in the air are filtered by the filter screen 27, they enter the air pump 12 through the other air inlet 28, and the filtered air is discharged to the outside through the discharge end of the air pump 12. Then, the discharge port 15 can be opened periodically to recycle the debris filtered inside the collection box 14.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
