[0033] Reference Figures 1 to 3 As shown, the outer sleeve of the power component is provided with a circular blade 6. As the main cutting component, the circular blade 6 has a sharp cutting edge and can cut the cloth quickly and efficiently. The outer sliding connection of the power component is provided with a limit plate 2 7, which can limit the front side of the circular blade 6. The rear side of the limit plate 2 7 contacts the front side of the circular blade 6 to ensure that the limit plate 2 7 can play a limiting role. The front side of the limit plate 1 5 contacts the rear side of the circular blade 6 to ensure that the limit plate 1 5 can play a limiting role. The front side of the limit plate 1 5 is fixedly connected to two clamping blocks 8, which can cooperate with the clamping slot 9 to further fix the circular blade 6;

[0034] The outside of the block 8 is slidably connected to the inside of the draw groove 9 to ensure that the block 8 and the draw groove 9 are tightly matched. The outside of the block 8 is slidably connected to the inside of the circular blade 6 to ensure that the block 8 can be firmly connected to the circular blade 6. The inside of the circular blade 6 is provided with two draw grooves 9, and the position and size of the draw grooves 9 are reasonably designed to perfectly match the block 8. The front side of the limiting piece 2 7 is provided with a fixing assembly for installation, and the fixing assembly includes a threaded groove 10, and the threaded groove 10 can cooperate with the bolt 11 to strengthen the connection between the limiting piece 2 7 and the circular blade 6. The outside of the threaded groove 10 is provided in the inside of the limiting piece 2 7 to ensure that the position of the threaded groove 10 is accurate. The internal thread of the threaded groove 10 is connected with the bolt 11, and the bolt 11 can firmly connect the limiting piece 2 7 and the circular blade 6 together.

[0035] Reference Figures 1 to 2 As shown, two protective covers 12 are fixedly connected to the front side of the mounting plate 1. The protective covers 12 can provide safety protection for the operator to prevent debris generated during the cutting process from flying. The left and right sides of the outside of the circular blade 6 are respectively rotatably connected to the adjacent sides of the two protective covers 12 to ensure that the rotation of the circular blade 6 will not be affected by the protective covers 12. The top of the protective cover 12 is fixedly connected to the bottom of the top plate 2 to ensure that the protective cover 12 is firmly installed. The bottom of the mounting plate 1 is fixedly connected to a connecting block 13, and the connecting block 13 can connect the lower pressing block 14 to the mounting plate 1. The bottom of the connecting block 13 is fixedly connected to a lower pressing block 14, and the lower pressing block 14 can provide pressure to the bottom blade 17 to ensure the cutting effect.

[0036] Reference Figures 4 and 5As shown, an upper baffle 15 is fixedly connected to the top of the lower pressure block 14. The upper baffle 15 prevents debris from flying upward during the cutting process. Two spring columns 16 are provided inside the lower pressure block 14. The spring columns 16 provide elastic support for the bottom blade 17, ensuring a tight fit between the bottom blade 17 and the circular blade 6. The bottom blade 17 is fixedly connected to the front side of the spring column 16, and the bottom blade 17 can work in conjunction with the circular blade 6 to improve cutting efficiency.

[0037] Two support columns 18 are fixedly connected to the bottom of the lower pressing block 14, providing stable support for the entire structure. A connection assembly is provided on the top of the top plate 2. This connection assembly includes multiple first mounting slots 19 and second mounting slots 20. These slots 19 and 20 provide positioning and securement for the installation of other components. The outer portions of the first mounting slots 19 are located on the top of the top plate 2, while the outer portions of the second mounting slots 20 are located on the top of the top plate 2.

[0038] Working Principle: Mounting plate 1 serves as the mounting base for the entire structure and is fixed to the corresponding position of the cloth spreading machine in conjunction with top plate 2. Mounting plate 1 provides support for components such as motor 3. After motor 3 is started, it drives circular blade 6 to rotate via connecting rod 4. Limiting piece 1 5 and limiting piece 2 7 are installed on either side of circular blade 6. Block 8 and slot 9 cooperate with each other to connect and fix circular blade 6, limiting its axial movement and ensuring that circular blade 6 remains stable during rotation. Threaded groove 10 and bolt 11 further strengthen the connection stability between the two.

[0039] When the motor 3 drives the circular blade 6 to rotate, the circular blade 6 and the bottom blade 17 work together. When the cloth needs to be cut, the circular blade 6 cooperates with the bottom blade 17 to cut the cloth from one direction. Due to the connection method of the block 8 and the slot 9 and the fixing effect of the threaded groove 10 and the bolt 11, the circular blade 6 and the bottom blade 17 can withstand a large cutting force and maintain a stable working state so that the circular blade 6 rotates in the forward direction. The bottom blade 17 is pressed on the cutting edge of the circular blade 6 through the spring column 16, and has an angle of about 30 degrees with the circular blade 6, which can cut the cloth coming in from the left. When the circular blade 6 reverses, it can cut the cloth coming in from the right, realizing the bidirectional cutting function of the cutter. This back and forth bidirectional cutting function improves the working efficiency and flexibility of the cloth stretching machine and meets different cloth cutting needs.

[0040] The protective cover 12 is mounted on the mounting plate 1 via the connecting block 13 to protect the operator and prevent the splashing of debris caused by cutting. The lower pressure block 14, upper baffle 15, spring column 16 and other components work together to provide a certain amount of pressure and cushioning during the cutting process, ensuring a stable cutting effect.

[0041] The support column 18 is installed at the bottom of the mounting plate 1 to provide stable support for the entire structure. The mounting groove 19 and the mounting groove 20 are used to install and position other components to ensure the position accuracy and working coordination between the various components.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
