[0025] The slitting positioning shaft 100 and the bed knife positioning shaft 500 are fixedly arranged on the slitting machine frame, and the driving roller 300 is rotatably arranged on the slitting machine frame.

[0026] During use, the staff pulls the outer end of the cloth roll to the top of the annular knife holder 200, and the cloth passes through the upper end of the annular blade 400. The staff rotates the bottom blade 600 downward so that the upper end of the annular blade 400 passes through the first knife groove 700. The bottom blade 600 presses the cloth downward. At this time, the cloth is between the bottom blade 600 and the top end of the annular knife holder 200, so that the cloth is tightened. The staff rotates the driving roller 300 through the control device, and the driving roller 300 drives the annular blade 400 to rotate to achieve cloth cutting.

[0027] Preferably, rotatable guide rollers 800 are respectively provided at the front and rear ends of the annular knife holder 200. The cloth passes through the upper end of the annular blade 400 while bypassing the two guide rollers 800. The guide rollers 800 are rotatably provided on the slitting machine frame. On the one hand, the guide rollers 800 support the cloth, and on the other hand, they drive the cloth to move through their own rotation, thereby realizing automatic slitting of the cloth.

[0028] Preferably, a sharpening opening 900 is provided at the bottom of the annular blade holder 200 , and a sharpening wheel 110 is fixedly provided on the outer side of the annular blade holder 200 , and the sharpening wheel 110 passes through the sharpening opening 900 and contacts the annular blade 400 .

[0029] Preferably, a mounting plate 120 is fixedly provided on the annular tool holder 200, and the sharpening wheel 110 is connected to the annular tool holder 200 via the mounting plate 120. The sharpening wheel 110 and the mounting plate 120 are fixedly connected. This arrangement makes the replacement of the sharpening wheel 110 more convenient.

[0030] Preferably, the annular tool holder 200 is provided with a bearing 130, and the driving roller 300 is mounted on the annular tool holder 200 through the bearing 130.

The number of the annular tool holders 200, the annular blades 400 and the bottom blades 600 is the same. By arranging multiple sets of annular tool holders 200, annular blades 400 and bottom blades 600 on the slitting knife mechanism, the slitting and cutting speed of the cloth is improved, and the production efficiency is improved.

[0035] The working principle of the embodiment is more specifically as follows:

[0036] The staff pulls the outer end of the cloth roll to make the cloth pass around the guide roller 800 and be fixed. At the same time, the cloth passes through the upper end of the annular blade 400 and falls on the cover plate 140. The staff pushes the handle 170 downward, and the handle 170 drives the bottom blade 600 to press downward, so that the upper end of the annular blade 400 passes through the first knife groove 700. The bottom blade 600 presses the cloth downward. At this time, the cloth is between the bottom blade 600 and the cover plate 140, and the cloth is tightened. The staff rotates the driving roller 300 through the control device, the driving roller 300 drives the annular blade 400 to rotate, and the cloth is cut. After the grinding wheel 110 is used for a period of time, the staff needs to replace the grinding wheel 110 to ensure the sharpness of the annular blade 400 and facilitate the cutting of the cloth.

[0037] The slitting knife mechanism of the utility model fixes and sets bottom knife positioning shaft 500 above driving roller 300, rotatably sets bottom knife piece 600 on bottom knife positioning shaft 500, sets first knife groove 700 on bottom knife piece 600, and the upper end of annular knife piece 400 passes through first knife groove 700, so that the cloth is always in the state of being taut when being cut, guarantees that the cloth can be easily cut, does not appear the situation of lotus root broken silk connection, and improves the cloth slitting efficiency.

[0038] The above only is the preferred embodiment of the utility model, and does not use to limit the utility model, and any modification, equivalent replacement and improvement etc. that are made within the spirit and principle of the utility model should fall within the protection scope of the utility model.
