[0031] Reference Figure 1-Figure 6 According to an embodiment of the utility model, a non-woven fabric slitting device with easy adjustment of the cutting knife spacing includes a frame 11, a fixed frame 13 is provided in the frame 11, a hinge groove 14 is provided in the left side surface of the fixed frame 13, a rotating shaft is rotatably connected in the hinge groove 14, and a connecting plate 15 is fixedly provided outside the rotating shaft, a knife rod 16 is rotatably connected in the connecting plate 15, and a plurality of circular cutters 17 distributed at equal distances front and back are provided outside the knife rod 16, a locking mechanism 101 for positioning the front and rear positions of the circular cutters 17 is provided on the knife rod 16, a slitting drum 12 is provided in the frame 11, a motor for driving the slitting drum 12 to rotate is provided in the frame 11, and a knife groove for accommodating the circular cutter 17 is provided in the curved surface of the slitting drum 12.

[0032] When the non-woven fabric is cut, the non-woven fabric is wound around the cutting drum 12 and conveyed. During this process, the non-woven fabric is cut by the circular cutting knife 17 extending into the cutting groove.

[0033] In addition, in order to facilitate the adjustment of the front and rear positions of the circular cutter 17 to adapt to the required width of the non-woven fabric after slitting, a fixing plate 18 is fixedly provided on the upper side of the fixing frame 13, and a slide groove 19 is provided on the left side of the fixing plate 18, and a plurality of positioning plates 20 are connected to the slide groove 19 for front and rear sliding connection, and the positioning plate 20 extends to the left to the left side of the slide groove 19, and a knife gap 21 is provided on the left side of the positioning plate 20 to pass through the upper and lower parts to accommodate the circular cutter 17, and a positioning mechanism for controlling the angle of the connecting plate 15 is also provided on the fixing frame 13.

[0034] In addition, a display slot is provided in the right side surface of the slide slot 19, and a control panel 22 is fixedly provided on the right side surface of the positioning plate 20, which passes through the display slot and extends to the right side of the fixed plate 18. The right side surface of the fixed plate 18 is provided with a scale close to the control panel 22 and displaying the position of the control panel 22.

[0035] The specific process of adjusting the front and rear positions of the circular cutter 17 is as follows: First, the staff adjusts the spacing between the positioning plates 20 according to the required width of the non-woven fabric, specifically: the staff controls the position of the positioning plate 20 by controlling the control plate 22. During this process, the staff can understand the position of the knife slit 21 in the positioning plate 20 according to the scale corresponding to the control plate 22;

[0036] After the position adjustment of the positioning plate 20 is completed, the staff adjusts the front and rear positions of the circular cutter 17, and then lifts the connecting plate 15 through the positioning mechanism, and tests whether the circular cutter 17 can be inserted into the corresponding knife slot 21 in the positioning plate 20. If the circular cutter 17 is matched with the knife slot 21 at this time, the staff resets the circular cutter 17 to the knife slot through the positioning mechanism, and the position adjustment and position detection of the circular cutter 17 are completed.

[0037] In addition, a No. 1 pressure plate 23 that can be attached to the positioning plate 20 is slidably connected up and down in the slide groove 19, and a No. 1 control rod 24 that is threadedly connected to the No. 1 pressure plate 23 is rotatably connected in the fixed plate 18. After the staff has adjusted the front and rear positions of the positioning plate 20, they can rotate the No. 1 control rod 24 and make the No. 1 pressure plate 23 press on the positioning plate 20 to avoid the positioning plate 20 from sliding when the position of the circular cutter 17 is subsequently detected, thereby affecting the detection result.

[0038] In this embodiment, the locking mechanism 101 includes an abutment groove 25 provided in the curved surface of the knife rod 16, a second pressure plate 26 is slidably connected in the abutment groove 25, and a second control rod 27 threadedly connected to the second pressure plate 26 is rotatably connected in the abutment groove 25;

[0039] The circular cutter 17 is provided with a plastic ring 28, which is sleeved on the outside of the cutter rod 16 and can be supported by the second pressure plate 26. Before adjusting the position of the circular cutter 17, the staff must control the second control rod 27 so that the second pressure plate 26 no longer contacts the plastic ring 28. At this time, the circular cutter 17 can be adjusted forward and backward. After the adjustment is completed, the staff can rotate the second control rod 27 and make the second pressure plate 26 stick to the plastic ring 28 to lock the front and rear position of the circular cutter 17.

[0040] The positioning mechanism includes a slot 29 arranged in the side of the connecting plate 15, a spring slot is arranged in the right side of the hinge slot 14, and a plug plate that can be inserted into the slot 29 is slidably connected to the spring slot left and right, and the plug plate is connected to the bottom surface of the spring slot through a spring. When the plug plate is inserted into the slot 29, the connecting plate 15 is in an inclined state and the circular cutter 17 moves into the knife slot. When it is necessary to make the circular cutter 17 enter the knife gap 21 to detect the front and rear position of the circular cutter 17, the staff needs to push the plug plate to the right and make it leave the slot 29.

[0041] In addition, in order to facilitate the staff to adjust the position of the circular cutter 17 midway so that it is adapted to the position of the knife slit 21, the positioning mechanism also includes an abutment plate 30 fixed to the left side of the fixing plate 18, and the abutment plate 30 is used to support the connecting plate 15. Figure 5 shown.

[0042] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
