The cutter 200 can be assembled and disassembled in a total process within a few seconds, compared with the traditional cutter, the assembly and disassembly time is greatly saved, so that the downtime of the slitting machine is greatly shortened when a group of cloth is cut each time, and the utilization efficiency of the slitting machine is improved. According to workshop statistics, when the cutter 200 is adopted, 40 groups of cloth can be cut in one day according to 8 hours of working, and compared with 24 groups when the traditional cutter is adopted, the production efficiency is greatly improved.
As shown in fig. 2, in one example, a side of the clamping mechanism 230 near the cutter fixing seat 220 is recessed inward, a side of the cutter fixing seat 220 near the clamping mechanism 230 is recessed inward, and when the clamping mechanism 230 is closed, two recessed portions form a mounting hole 250. In this example, the mounting hole 250 is generally circular. In other examples, the mounting hole 250 may have other shapes, such as square, oval, triangular, or irregular shapes, etc., to enable the fit with the slitter knife block.
As shown in fig. 2, in one example, the concave portion of the side, close to the clamping mechanism 230, of the cutter fixing seat 220 is further provided with a positioning groove 221 of a cutter holder of the slitting machine, and the positioning groove 221 of the cutter holder of the slitting machine is used for being matched with a protrusion on the cutter holder of the slitting machine to position the mounting position of the cutter. In other examples, the slitter knife rest positioning groove 221 can also be provided in a recessed portion of the side of the detent mechanism 230 proximate to the knife holder 220.
Alternatively, the limiting member 242 and the rotating rod 241 may be non-detachable, such as integrally formed, or may be detachably connected, such as by screwing.

In this way, the position of the stopper 242 on the rotating lever 241 can be adjusted, and the degree of compression of the spring 243 can be flexibly adjusted when the cutter is mounted. In the specific example shown in fig. 2, the rotating rod 241 is provided with threads, and the limiting member 242 is two nuts, so that the connection strength can be improved.
The spring 243 has a larger elastic coefficient, and the elastic coefficient can be specifically determined according to factors such as cutter size, weight and the like, so that the stability of cutter installation can be ensured.
It can be understood that the spring 243 and the limiting member 242 may be separated, and when the cutter is installed, the spring 243 abuts against the limiting member 242, so that the manufacture is convenient; the spring 243 and the limiting member 242 may be fixedly connected with each other, for example, a silicone tube is sleeved outside the spring 243 for connection, which is convenient for personnel to operate.
In one example, the rotating rod 241 has a step structure (not shown), the pressing member 244 is sleeved on the smaller diameter section of the rotating rod 241, the pressing member 244 is disposed between the step structure and the spring 243, and the pressing member 244 abuts against the step structure, so as to limit the pressing member 244.
The pressing member 244 may slide on the rotating rod 241, for example, the pressing member 244 may be a slide nut. It can be appreciated that the compressing member 244 and the spring 243 may be separated, and when the cutter is installed, the compressing member 244 abuts against the spring 243, so that the manufacturing is convenient, and the compressing member 244 and the spring 243 may be fixedly connected with each other, so that the operation of personnel is convenient.
In the specific example shown in fig. 2, the slot wall 232 of the positioning slot 231 at the opening of the side far away from the cutter fixing seat 220 is designed as a rounded corner. In this way, the resistance between the hold-down 244 and the slot wall 232 of the detent 231 can be reduced, and the hold-down 244 can be easily slid into place when the tool is installed.
In the specific example shown in fig. 2, the end of the pressing member 244 for pressing against the detent mechanism 230 is rounded. As such, the resistance between the pressing member 244 and the groove wall 132 of the positioning groove 231 can be reduced.
