[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0029] Reference Figure 1-9 The utility model discloses a cloth scrap cleaning device for a guide cloth slitting machine, comprising a brush 3 installed below a lower disc knife 2, the brush 3 having a width consistent with a knife groove 4 in the lower disc knife 2, the brush 3 being aligned with the knife groove 4 where an upper disc knife 1 is located, the brush 3 comprising bristles 6 and a bristle seat 7, the bristles 6 being arranged on the bristle seat 7, the end of the bristles 6 away from the bristle seat 7 extending into the interior of the knife groove 4.
[0030] The slitting machine includes a frame, an upper disc knife 1, and a lower disc knife 2. The upper disc knife 1 and the lower disc knife 2 are respectively rotatably installed on the frame and driven to rotate by an external motor. The middle of the lower disc knife 2 is a knife groove 4. There are multiple upper disc knives 1 and lower disc knives 2. In the present application, the spacing of the upper disc knife 1 along its own transmission shaft is adjustable, and the lower disc knives 2 are closely arranged on their own transmission shaft.
[0031] The depth of the brush bristles 6 extending into the knife groove 4 is determined by the position of cloth scraps adhering to the inner wall of the knife groove 4 during the production process, and it is sufficient to ensure that the brush bristles 6 can sweep away the cloth scraps on the inner wall of the knife groove 4.
[0032] When in use, the guide cloth passes through between the upper disc knife 1 and the lower disc knife 2, and the upper disc knife 1 cuts into the knife groove 4 to cut the guide cloth.
[0033] After the cloth scraps produced by slitting fall into the knife groove 4, they stick to the side wall of the knife groove 4, and then as the lower disc knife 2 rotates, it contacts the brush 3, and the bristles 6 sweep the cloth scraps on the side wall of the knife groove 4 to prevent the cloth scraps from accumulating and falling and sticking to the guide cloth after slitting.
[0034] The bristle holder 7 is a disc structure, and the bristles 6 are evenly distributed in the circumferential direction of the bristle holder 7 .
[0035] The bristle holder 7 is rotatably mounted on the frame. Rotating the bristle holder 7 drives the bristles 6 to rotate, adjusting the contact between the bristles 6 at different positions on the bristle holder 7 and the side wall of the knife groove 4, reducing the wear rate of the bristles 6 and extending the overall service life of the brush 3.
[0036] An axial hole 14 is provided inside the brush holder 7 , and a brush shaft 8 is provided inside the axial hole 14 . One end of the brush shaft 8 is connected to the working end of the driving source, and the brush holder 7 and the brush shaft 8 are clamped together.
[0037] The driving source is a motor, which drives the brush shaft 8 to rotate, and further drives the brush 3 to rotate. The bristles 6 are in dynamic contact with the side wall of the knife groove 4, so that the cloth scraps in the knife groove 4 are swept out, thereby improving the cleaning effect.
[0038] In the prior art, the transmission shafts of the upper disc knife 1 and the lower disc knife 2 can be detachably mounted on the frame, and the brush shaft 8 can be detachably mounted on the frame in the same manner. When the brush 3 needs to be replaced, the brush shaft 8 is first removed, and then the brush 3 is removed from the brush shaft 8 for replacement.
[0039] A guide groove 10 is provided on the circumferential surface of the brush shaft 8 along the axial direction, and a guide block 13 corresponding to the guide groove 10 is provided on the inner wall of the shaft hole 14 , and the guide block 13 is slidably connected to the guide groove 10 .
[0040] The number of the brushes 3 is not less than the number of the upper disc cutters 1. When in use, the guide block 13 is aligned with the guide groove 10, and the brush seat 7 is slidably sleeved on the brush shaft 8 from one end of the brush shaft 8.
[0041] A clamping groove 9 is provided on the side of the brush shaft 8 away from the guide groove 10, and a clamping block 11 corresponding to the clamping groove 9 is provided inside the shaft hole 14. The clamping block 11 is slidingly connected to the clamping groove 9. A bolt hole 12 is provided on the clamping block 11 along the radial direction of the brush shaft 8, and the bolt hole 12 passes through the clamping block 11.
[0042] The clamping groove 9 is also opened along the axial direction of the brush shaft 8. When installing the brush 3, the guide block 13 is aligned with the guide groove 10, the clamping block 11 is aligned with the clamping groove 9, and then the brush seat 7 is slidably sleeved on the brush shaft 8.
[0043] A tightening bolt is installed in the bolt hole 12 , and the head of the tightening bolt presses against the brush shaft 8 , thereby fixing the brush holder 7 at a specified position of the brush shaft 8 , so that the brush 3 is aligned with the knife groove 4 cut by the upper disc knife 1 .
[0044] During use, the position of the upper disc knife 1 on its own transmission shaft is determined by the slitting width of the guide cloth, and the position of the brush 3 is aligned with the upper disc knife 1 .
[0045] A dust suction groove 5 is arranged on one side of the brush 3 away from the discharge end of the lower disc knife 2. The dust suction groove 5 faces the brush 3, and the brush 3 is connected to the air inlet of the dust suction device.
[0046] In this application, if Figure 6 As shown, the discharge end of the lower disc knife 2 is located at the left end of the lower disc knife 2, and the dust suction groove 5 is installed at the lower right side of the lower disc knife 2, which is also the lower right side of the brush 3.
[0047] exist Figure 6 In the embodiment, the upper disc knife 1 rotates clockwise, the lower disc knife 2 rotates counterclockwise, and the guide cloth passes between the upper disc knife 1 and the lower disc knife 2 from right to left. At the same time, the brush shaft 8 and the brush 3 are driven by the driving source to rotate clockwise to sweep the cloth scraps backwards. The swept cloth scraps are sucked away by the dust collection device through the dust collection groove 5 to prevent the cloth scraps from being scattered into the air.
[0048] The axial length of the dust suction groove 5 is greater than the axial length of the lower disc cutter 2 , and the movement path of the end of the bristles 6 away from the bristle holder 7 passes through the inner side of the dust suction groove 5 .
[0049] Since the overall axial length of the multiple brushes 3 is smaller than the overall axial length of the multiple lower disc cutters 2, the axial length is greater than the dust suction groove 5 of the lower disc cutter 2, which can wrap all the brushes 3 and reduce the situation where the cloth scraps swept by the brushes 3 float to the outside of the dust suction groove 5.
[0050] The opening edge of the dust suction groove 5 is provided with bristles 6, and the bristles 6 include an inclined plate 15 and a side plate 16. The side plate 16 is arranged along the axial direction of the lower disc knife 2. The side plate 16 is located on the side of the dust suction groove 5 away from the discharge end of the lower disc knife 2. The side plates 16 are arranged at both ends of the inclined plate 15.
[0051] The dust suction groove 5 is a trumpet-shaped groove structure with a cross section in the side view direction, which is larger at the top and smaller at the bottom. The top of the dust suction groove 5 is open, and the opening of the dust suction groove 5 faces the brush 3 .
[0052] like Figure 6As shown, the top of the inclined plate 15 is slightly higher than the top of the brush 3. After the bristles 6 enter the knife groove 4 to sweep the cloth scraps, when coming out of the knife groove 4, they sweep the cloth scraps obliquely downward to the inner wall of the inclined plate 15 and then enter the dust collection groove 5.
[0053] One end of the side plate 16 close to the brush shaft 8 is a concave arc structure to avoid interference with the brush shaft 8. When the brush shaft 8 is removed to replace the brush 3, there is no need to remove the side plate 16, which facilitates replacement of the brush 3.
[0054] Working principle: When in use, the guide cloth material to be cut passes between the upper disc knife 1 and the lower disc knife 2, and the upper disc knife 1 cuts into the knife groove 4 to complete the cutting of the guide cloth.
[0055] After the cloth scraps produced by slitting adhere to the inner wall of the knife groove 4, as the lower disc knife 2 rotates and contacts the brush 3, the bristles 6 sweep the cloth scraps out of the knife groove 4 and sweep them into the dust suction groove 5, thereby preventing the cloth scraps from accumulating in the knife groove 4 and then falling onto the guide cloth after slitting, thereby completing the cleaning work of the slitting machine.
