The fabric passes through the bottom of the pressing roller (45). Pressing with the pressing roller (45) can make the fabric fit the protective pad (41) and can also make the fabric straight, which is convenient for cutting. S2: Fabric cutting: By driving the gear (6) to rotate through the first motor (8), the lifting rod (4) can be moved up and down under the action of the tooth groove (5). When the lifting rod (4) moves down, the blade (7) can move down and fit with the fabric. When the pressing roller (45) pulls the fabric to move, the blade (7) will cut the fabric. The protective pad (41) can protect the cutting table (1) during the cutting process. S3: Blade Cleaning: After cutting, the gear (6) can be rotated in the opposite direction by the reverse drive of the first motor (8), which in turn causes the lifting rod (4) to move upward. When the gear (6) rotates, the winding roller (9) will rotate synchronously and wind up the rope (10). Under the action of the traction block (18) and the connecting rod (17), the slider (12) can be pulled forward. When the blade (7) rises to the top, the cleaning head (20) will move to the outside of the blade (7). The pulley (24) is driven by the dual-axis motor (23). Under the action of the synchronous belt (25), the rotating head (21) can be moved. The non-woven fabric (22) can wipe the blade (7), thereby keeping the blade (7) clean and ensuring that the cutting edge is smooth, reducing fabric fraying and tearing, thus improving the cutting effect. The air pump (33) is started to draw air, which can generate negative pressure in the branch pipe (34). Under the conduction of the connecting pipe (31), suction can be generated at the suction groove (29), which can absorb the heat emitted by the blade (7). At the same time, it can absorb the fabric fibers that fly out of the cleaning blade. The air filter in the filter cylinder (35) can filter the fabric fibers in the drawn air, and the filter screen (30) can filter the impurities in the air.
