Description

Technical Field

[0001] This utility model relates to a cutting accessory, and more specifically, to a leather cutting head for shoemaking. Background Technology

[0002] Leather cutting heads for shoemaking are key equipment components used in the shoemaking industry for the precise cutting of leather materials. Their core function is to efficiently cut components such as shoe uppers and linings according to design requirements. They are usually installed on assembly line machinery. In existing technology, straight blade cutting is usually used for cutting rough leather. However, in actual use, it has been found that in small workshops and factories, due to the lower requirements for the fineness of the leather and cost considerations, the leather is often rough and may have a small amount of residual tendons. Although this does not affect the use of leather products, it can cause the tendons to get stuck on the straight blade during cutting. If force is continued, it may even cause the leather to tear. Therefore, a leather cutting head for shoemaking is needed that can cut through tendons and other parts without getting stuck.

[0003] For the reasons mentioned above, the problem addressed in this application is how to cut through tendons and other parts of the meat without getting stuck. Utility Model Content

[0004] To address the shortcomings of existing technologies, a leather cutting head for shoemaking is provided, which can cut through meat tendons and other parts without getting stuck.

[0005] To achieve the above objectives, the following technical solution is provided: a leather cutting head for shoes, comprising a mounting shell, a suction component, a cutting component, and a safety component. The cutting component is rotatably connected to the mounting shell, the safety component is slidably connected to the mounting shell, and the suction component is mounted on the side of the mounting shell and connected to the cutting component.

[0006] After the safety assembly moves toward the mounting housing, the cutting assembly can rotate.

[0007] In summary, the above technical solution has the following beneficial effects: the mounting shell serves as the main frame, bearing all components and fixing them to the equipment, providing stable support and mechanical movement guidance; the suction component is located on the side of the mounting shell, adsorbing the debris generated after the leather material is cut by negative pressure, which facilitates environmental cleanliness; it can also directly separate the debris generated after the leather material is cut by blowing out gas, but this will pollute the surrounding environment and is only used in unconventional situations; the cutting component is rotatably connected to the mounting shell through a rotating shaft, and cutting is achieved by rotation; the safety component is slidably connected to the mounting shell, usually a mechanical locking mechanism, used to forcibly control the stop of the cutting component;

[0008] The rotating cutting component achieves continuous cutting through rotational motion, eliminating the need for frequent start-stop operations. It is particularly suitable for cutting long distances or curved paths, significantly improving production efficiency. When cutting large curved contours of leather, it can be done in one go, while straight blades require multiple reciprocating motions, which is slower. Furthermore, the cutting angle can be dynamically adjusted to reduce material resistance, preventing deformation or displacement of the leather due to uneven force, avoiding getting stuck when cutting tendons, and preventing the leather from tearing.

[0009] By default, the safety component is in the extended position, that is, away from the mounting shell, and is forcibly pressed against the rotating part of the cutting component by means of a physical latch, thereby preventing the cutting component from rotating and preventing it from starting, thus preventing accidental or unintentional activation.

[0010] During operation, workers can slide the safety component towards the mounting housing by pressing it, which also allows the leather to come into contact with the cutting component. This releases the locking mechanism of the safety component, allowing the cutting component to rotate and cut the leather.

[0011] This invention ensures safe use through the physical structure of the safety component. If an accident occurs during the cutting process, the safety component can be used immediately to stop the cutting component. The cutting component, through its rotating connection design, allows the blade to automatically adjust the cutting angle according to the path, reducing blade wear and improving edge smoothness, and achieving the purpose of cutting meat tendons and other parts without getting stuck.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0020] Reference Figure 1-2 As shown, the shoe leather cutting head includes a mounting shell 1, a suction component 2, a cutting component 3, and a safety component 4. The cutting component 3 is rotatably connected to the mounting shell 1, the safety component 4 is slidably connected to the mounting shell 1, and the suction component 2 is mounted on the side of the mounting shell 1 and connected to the cutting component 3.

[0021] After the safety component 4 moves toward the mounting housing 1, the cutting component 3 can rotate.

[0022] Mounting housing 1 serves as the main frame, bearing all components and fixing them to the equipment, providing stable support and mechanical movement guidance. Suction component 2 is located on the side of mounting housing 1, using negative pressure to absorb the debris generated after the leather material is cut, in order to maintain environmental cleanliness. Alternatively, it can directly separate the debris generated after the leather material is cut by blowing out gas, but this will pollute the surrounding environment and is only used in unconventional situations. Cutting component 3 is rotatably connected to mounting housing 1 via a pivot, and cutting is achieved by rotation. Safety component 4 is slidably connected to mounting housing 1, usually a mechanical locking mechanism, used to forcibly control the stop of cutting component 3.

[0023] The rotating cutting component 3 achieves continuous cutting through rotational motion, eliminating the need for frequent start-stop operations. It is particularly suitable for cutting long distances or curved paths, significantly improving production efficiency. When cutting large curved contours of leather, it can be done in one go, while straight blades require multiple reciprocations and are slower. Furthermore, the cutting angle can be dynamically adjusted to reduce material resistance, preventing deformation or displacement of the leather due to uneven force, avoiding getting stuck when cutting tendons, and preventing the leather from tearing.

[0024] By default, the safety component 4 is in the extended position, that is, away from the mounting shell 1, and is forcibly pressed against the rotating part of the cutting component 3 by means of a physical latch, thereby preventing the cutting component 3 from rotating and preventing it from starting, thus preventing accidental activation.

[0025] During operation, the worker can slide the safety component 4 towards the mounting shell 1 by pressing it, which also allows the leather to come into contact with the cutting component 3. This releases the locking structure of the safety component 4, allowing the cutting component 3 to rotate and cut the leather.

[0026] This utility model ensures safe use through the physical structure of the safety component 4. If an accident occurs during the cutting process, the safety component 4 can be used immediately to stop the cutting component 3. The cutting component 3, through its rotating connection design, allows the blade to automatically adjust the cutting angle according to the path, reducing the wear of the blade 32 and improving the edge smoothness, and achieving the purpose of cutting meat tendons and other parts without getting stuck.

[0027] Furthermore, the cutting assembly 3 includes a hollow tube 31 and a blade 32. The blade 32 is fixedly connected to the hollow tube 31. The blade 32 is semi-circular in shape and the cutting head is located on the side. The end of the hollow tube 31 away from the blade 32 is connected to the suction assembly 2.

[0028] Furthermore, the cutting assembly 3 also includes a rotating shaft 33 and a clamping member 34. The clamping member 34 is detachably connected to the hollow tube 31, and the rotating shaft 33 is fixedly connected to the clamping member 34. Both the clamping member 34 and the rotating shaft 33 are rotatably connected to the mounting shell 1. The end of the rotating shaft 33 away from the clamping member 34 extends to the outside of the mounting shell 1.

[0029] Since the blade 32 mainly operates in a rotary cutting mode, the cutting head needs to be placed on the side of the blade 32, and the cut leather parts and debris can be directly sucked away by the suction component 2 through the hollow tube 31, thereby avoiding affecting subsequent cutting operations.

[0030] Furthermore, the suction assembly 2 includes a receiving chamber 21, an extension chamber 22, and a connection port 23. The receiving chamber 21 is fixedly connected to the mounting shell 1, the extension chamber 22 is fixedly connected to the receiving chamber 21, and the connection port 23 is fixedly connected to the extension chamber 22. The receiving chamber 21, the extension chamber 22, and the connection port 23 are connected in communication, and the connection port 23 is used to connect an air pump.

[0031] Furthermore, the receiving chamber 21 is located at one end of the hollow tube 31 near the clamping member 34, and the hollow tube 31 is provided with a first opening 311, which is located inside the receiving chamber 21.

[0032] Furthermore, the suction assembly 2 also includes an impeller 24 and a collection funnel 25. The hollow tube 31 is also provided with a second opening 312, which is located inside the collection funnel 25 and close to the neck of the collection funnel 25. The collection funnel 25 is fixedly connected to the hollow tube 31, and the impeller 24 is fixedly connected to the collection funnel 25 and close to the funnel opening of the collection funnel 25.

[0033] The suction component 2 mainly relies on an additional air pump to achieve the suction function. Inside this utility model, there are two positions for removing debris. The first position is located at the blade head. Since the blade head mainly relies on arc cutting, the cut leather debris can be directly sucked away from the top of the hollow tube 31. The second position is located at the second opening 312 of the hollow tube 31. When the hollow tube 31 rotates, it will drive the impeller 24 to rotate at high speed, thus forming a vacuum cleaner structure for cleaning fine debris. The collection funnel 25 can prevent debris from flying around. Both allow debris to enter the receiving chamber 21 from the first opening 311 and then be discharged through the connecting port 23. The connecting port 23 can be replaced according to the actual air pump model used.

[0034] Furthermore, the safety component 4 includes a movable part 41 and a plurality of plug-in parts 42, and the suction component 2 also includes an abutment part 26, the abutment part 26 being fixedly connected to the collection funnel 25, the movable part 41 being slidably connected to the mounting shell 1, the plug-in parts 42 being fixedly connected to the movable part 41, and the plug-in parts 42 being used to abut the abutment part 26.

[0035] When the moving part 41 is not in contact with the leather, the plug 42 abuts against the contacting part 26, and the plug 42 prevents the hollow tube 31 from rotating;

[0036] When the movable part 41 comes into contact with the leather, the movable part 41 moves, the plug 42 separates from the contacting part 26, and the hollow tube 31 rotates.

[0037] Furthermore, the safety component 4 also includes a roller 43, which is rotatably connected to the movable component 41.

[0038] The connector 42 and the abutment 26 are the core components of the safety structure. The movement of the moving part 41 can determine whether the safety structure is working, while the roller 43 can reduce friction by rolling, thereby protecting the leather.

[0039] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
