in addition, two first lower sewing body through holes 1221 and two first cutter through holes 1222 are respectively formed at the upper and lower ends of the lower cutter holder 122, two second lower sewing body through holes 41 are formed in the lower sewing body, and two second cutter through holes 1211 are formed in the fixed cutter member 121, so that the fixed cutter group 12 can be fixed on the lower sewing body through the second lower sewing body through holes 41 and the first cutter through holes 1222; the stationary blade member 121 may be fixed to the lower blade holder 122 by the first and second cutter through holes 1222 and 1211.
FIG. 9 is a schematic view of a movable blade member and a stationary blade member according to an embodiment. As shown in fig. 9, the movable knife group 11 and the fixed knife group 12 are opposite and fit;
when the movable cutter set 11 and the fixed cutter set 12 move along the cutting direction, the movement tracks are partially overlapped, so that the cloth is cut when the movable cutter set 11 and the fixed cutter set 12 are contacted; the movable blade member 111 at least has a movable blade face 1114 positioned in the blade face direction, a movable blade side 1115 positioned in the blade side direction, a movable blade back 1116 positioned in the back direction and a movable blade 1117 arranged opposite to the movable blade back; wherein, the moving blade 1117 is arranged obliquely compared with the cutting direction; the stationary blade member 121 has at least a stationary blade surface 1223 located in the blade surface direction, a stationary blade side 1224 located in the blade side direction, a stationary blade back 1225 located in the back direction, and a stationary blade edge 1226 located in the blade edge direction of the stationary blade member 121; the movable blade edge 1117 contacts the fixed blade member 121 while moving in the cutting direction.
The fixed blade edge 1226 is disposed opposite to the fixed blade back 1225, and the fixed blade face 1223 has a movable blade side blade face and an opposite side blade face, the movable blade side blade face extends from the fixed blade edge toward the fixed blade back, and the movable blade side blade face inclines toward the opposite side blade face. The movable blade flank is a side close to the movable blade member 111, and the different flank is a side relatively far from the movable blade member 111. Therefore, the movable blade 1117 is always in contact with one end of the movable blade flank of the fixed blade 1226, and does not subsequently contact the movable blade flank, so as to avoid interference and collision between the movable blade 111 and the fixed blade 121.
From a macroscopic perspective, in the present embodiment, the upper end of the stationary blade member 121 is wider than the lower end; in addition, referring to fig. 1, the right side of the fixed blade member 121 shown in fig. 8 is connected to the lower knife base 122, so when the movable blade member 111 and the fixed blade member 121 work, the right side of the fixed blade member 121 should be vertically arranged, and the left end of the fixed blade member 121 slightly protrudes to ensure that the movable blade member 111 can contact with the fixed blade member 121. Meanwhile, the guiding inclined plane 1113 of the guiding block 1112 is slightly recessed inwards and is just matched with the fixed knife member 121, so that the movable knife member 111 is not collided or interfered when being contacted with the fixed knife member 121, the position change of the movable knife member 111 and the fixed knife member 121 is avoided, and the stability of the cutting device is improved.
As shown in fig. 9, the lower end surface of the movable blade member 111 is provided with a first inclined surface 1111, the upper end surface of the fixed blade member 121 is also provided with a second inclined surface 1212, and the inclined directions of the two are opposite to each other, so that when the movable blade member 111 and the fixed blade member 121 are in contact with each other and work, the cloth is cut in a scissors-like manner, and the cutting process is smoother.
As shown in fig. 9, a guide block 1112 protrudes from the bottom end of the movable blade member 111, and the guide block 1112 is used for guiding the movable blade member 111 to contact with the stationary blade member 121. The guiding block 1112 is located on a relatively lower side of the first inclined surface 1111 of the movable blade member 111, so as to contact with a relatively higher side of the second inclined surface 1212 of the fixed blade member 121 first, thereby playing a guiding role.
Fig. 10 is an enlarged view of a portion a in fig. 9. As shown in fig. 10, the guide block 1112 has a guide slope 1113. And the guide slope 1113 is inclined in the opposite direction to the inclined surface of the movable blade member 111. Such a design prevents the guide block 1112 from interfering with the stationary blade member 121 to affect the cutting effect and even change the positions of the movable blade member 111 and the stationary blade member 121.
Finally, in the present embodiment, the cylinder member 21 is disposed above the cutting device to move the movable blade group 11, but in actual manufacturing, the cylinder member 21 may be disposed below the cutting device to move the movable blade group 11, and at this time, the blade surface direction adjusting unit 31 may adjust the position direction of the movable blade group 11 located at the lower end, and the fixed blade group 12 is located at the upper end of the cutting device.
The working principle is as follows: when the cutting device and the sewing machine improved by the embodiment are used, firstly, the direction of the movable blade member 111 needs to be adjusted according to needs; the movable blade member 111 moves forwards or backwards by applying force to the blade surface direction adjusting assembly 31 through the annular hole 311; meanwhile, the left and right directions of the movable blade member 111 are adjusted by rotating the connecting column 1121; after the adjustment is completed, the cylinder member 21 is started, and the cylinder member 21 drives the movable blade member 111 to move towards the fixed blade member 121 along the guide rail 33, so that the movable blade member 111 and the fixed blade member 121 are matched for processing.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
