[0002] Oxford cloth textile is a multi-purpose fabric, commonly found in products such as clothing, luggage, canvas shoes and tents. It is favored for its wear resistance, tear resistance and water resistance. In order to meet the design requirements and production needs of different products, cloth cutting machines for Oxford cloth textile came into being. The structure of the equipment mainly includes the main frame, tool system, transmission system, control system and auxiliary devices. The tool system is its core component, which consists of a blade, a tool holder and a tool shaft. It is made of high-speed steel or carbide to ensure the accuracy and efficiency of cutting. The transmission system drives the tool system to perform cutting operations, and uses components such as motors and reducers to ensure stable power output and cutting speed. The control system adjusts the cutting size and speed through the electrical control cabinet and PLC controller. Auxiliary devices such as racks and feeding devices assist in the positioning and discharge of fabrics, further improving cutting efficiency and accuracy;

[0028] The lifting type cloth cutting mechanism 6 actively applies force downward, and the blade portion of the lifting type cloth cutting mechanism 6 applies force to the steel roller 8 until the Oxford cloth wrapped around the steel roller 8 is cut;

[0029] The toothed double-roller feeding assembly 3 comprises an upper feeding roller 302 and a lower feeding roller 303 rotatably mounted on the upper and lower sides of the U-shaped frame 1, and a vertical plate 301 mounted on the outer wall of one side of the U-shaped frame 1. One end of the upper feeding roller 302 and the lower feeding roller 303 penetrates the outside of the vertical plate 301 and is equipped with a gear transmission structure 304 for power connection. When the Oxford cloth is conveyed by the toothed double-roller feeding assembly 3, the lower feeding roller 303 is actively driven by the stepping motor 7 to move, and the gear transmission structure 304 is driven by the lower feeding roller 303 to rotate through the gear transmission structure 304. In this process, the upper feeding roller 302 and the lower feeding roller 303 rotate in opposite directions.

[0030] When the Oxford cloth passes through the gap between the upper feeding roller 302 and the lower feeding roller 303, the two can actively convey the Oxford cloth. During the conveying of the cloth, the steel roller 8 holds up and supports the Oxford cloth. The toothed double-roller feeding assembly 3 and the steel roller 8 convey the cloth in an S-shaped manner, which simplifies the conveying process of the cloth. At the same time, the lifting cloth cutting mechanism 6 can also control the cutting process more flexibly.

[0033] When the Oxford cloth needs to be cut, the Z-axis cylinder 601 and the second cylinder 604 are controlled by the PLC control panel 2 to move, and the second cylinder 604 controls the cutter 606 to suspend above the steel roller 8, and the Z-axis cylinder 601 pulls the slide bar 602, the second cylinder 604, the inverted U-shaped block 603, the cutter 606 and other components downward until the blade of the cutter 606 applies force to the Oxford cloth and cuts it. The lifting type cloth cutting mechanism 6 cuts the cloth immediately to reduce waiting time.

[0034] When the embodiment of the present application is used, first, the staff bypasses the Oxford cloth to be cut from one side of the cloth limiting mechanism 4 and feeds it into the gear-type double-roller feeding assembly 3, and the Oxford cloth is then wound out from between the steel roller 8 and the gear-type double-roller feeding assembly 3 in an S-shaped routing manner. Then, the staff turns on the stepper motor 7 and the cloth limiting mechanism 4 through the PLC control panel 2 to work, and the stepper motor 7 drives the gear-type double-roller feeding assembly 3 and conveys the Oxford cloth. The cloth limiting mechanism 4 presses the Oxford cloth on the upper roller of the gear-type double-roller feeding assembly 3 to ensure that the Oxford cloth is stably conveyed between the gear-type double-roller feeding assembly 3 and the steel roller 8. When the Oxford cloth is conveyed to a certain length and needs to be cut, When the cloth is cut off, the staff turns off the stepper motor 7 through the PLC control panel 2, so that the gear double-roller feeding component 3 stops moving, and starts the lifting type cloth cutting mechanism 6 to work, and the lifting type cloth cutting mechanism 6 actively applies force downward, and the blade part of the lifting type cloth cutting mechanism 6 applies force to the steel roller 8 until the Oxford cloth bypassing the steel roller 8 is cut.
