[0030] Two protective side plates 20 are relatively arranged on the outside of the cylinder 7, and a number of bolts are arranged between the protective side plates 20 and the mounting plate. A guide rod 21 is arranged on the inside of the fixing frame 2, and the guide rod 21 passes through the movable block 4, and the movable block 4 and the guide rod 21 are slidably matched. The protective side plates 20 effectively isolate and protect the cutter 8, and the guide rod 21 effectively limits and guides the movable block 4, thereby ensuring the stability of the movable block 4 moving up and down.

[0031] A cloth placing roller 22 is installed on one side of the top of the processing table 1 through a bracket, and two cloth guide rollers 23 are arranged on the processing table 1 opposite to each other. The cloth guide roller 23 is arranged on the side of the tensioning roller 15 away from the fixed frame 2. A movable roller 24 is arranged on the side of the processing table 1 away from the cloth placing roller 22 through a mounting frame, and a second electric push rod 25 is connected between the mounting frame and the processing table 1. The cloth placing roller 22 is used to facilitate the release of the cloth to be cut, and the cloth guide roller 23 is combined to facilitate the preliminary guiding and tensioning of the cloth before and after cutting. The second electric push rod 25 is used to facilitate the up and down movement of the movable roller 24, and further tension the cloth after cutting, so as to facilitate the winding of the cloth after cutting.

[0032] Example:

[0033] When in use, firstly, according to the actual size of the fabric to be cut, the sliding sleeve 6 is adjusted to slide along the direction of the fixed rod 5, and the distance between two adjacent sliding sleeves 6 is controlled under the cooperation of the pointer 10 and the scale 9, so as to achieve the purpose of controlling the distance between two adjacent cutters 8. After the distance between the cutters 8 is adjusted, the screw 16 is rotated to drive the clamping block 18 downward and clamp it into the clamping groove 17 at the top of the fixed rod 5, so as to limit and fix the sliding sleeve 6, so as to achieve the purpose of fixing the cutter 8;

[0034] Then the end of the cloth on the cloth-releasing roller 22 is pulled out, and the end of the cloth is preliminarily cut according to the actual situation. Then the cut cloth end is passed through the lower side of the left cloth guide roller 23, the upper sides of the two tensioning rollers 15, the lower side of the right cloth guide roller 23, and the upper side of the movable roller 24 in sequence, and finally wound on the outer winding mechanism, and the second electric push rod 25 is started to adjust the movable roller 24 to move up to a suitable height to preliminarily tension the cloth;

[0035] Secondly, the first electric push rod 3 is started, and the movable block 4 is pushed to move downward steadily under the sliding cooperation with the guide rod 21, which drives the fixed rod 5 to move downward, and under the action of the sliding sleeve 6, the cutter 8 is driven to move in the direction of the lower side cloth, and at the same time, the cylinder 7 is started to push the cutter 8 to move downward to the outside of the protective side plate 20 and align with the cutting position of the cloth;

[0036] In the process of the movable block 4 moving downward, the first piston rod 13 is driven to move into the first cylinder 11, and the hydraulic oil in the first cylinder 11 is squeezed into the second cylinders 12 on both sides. As the amount of hydraulic oil in the second cylinder 12 increases, the second piston rods 14 on both sides are pushed upward, thereby driving the two tensioning rollers 15 to move upward, pushing the cloth upward, so that the cloth is tensioned, ensuring the stability of the cloth during the slitting process and preventing the cloth from becoming loose.

[0037] Finally, the cloth is released by the cloth-releasing roller 22, and the slit cloth is reeled up in combination with the external reeling mechanism, so that the cloth moves to the right under the cutter 8, and the slitting of the cloth is completed;

[0038] When the required number of cuts is small, the redundant sliding sleeves 6 are moved to the two ends of the fixed rod 5 and fixed. When the cutter 8 needs to be replaced and repaired, the sliding sleeve 6 is adjusted to rotate along the fixed rod 5 to drive the corresponding cutter 8 to flip to the upper side of the fixed rod 5, and at the same time, the screw 16 on the corresponding sliding sleeve 6 is adjusted so that the block 18 is inserted into the slot 17 on the lower side of the fixed rod 5 to stabilize the cutter 8 on the upper side of the fixed rod 5, and then the bolts between the protective side plate 20 and the mounting plate are removed to expose the cutter 8, which is convenient for the staff to repair and replace the cutter 8.
