[0024] The preferred embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings.

[0025] Reference Figures 1 to 6 The utility model provides a slitting machine for convenient shearing, including a frame, side plates 1 are symmetrically arranged on both sides of the frame, and rotating plates 2 are rotatably connected to the side plates 1. A tool assembly is arranged between the rotating plates 2. The tool assembly is arranged in three groups and is evenly distributed at an angle of 120 degrees. The tool assembly includes a connector 11 rotatably arranged on the inner side of the rotating plate 2, a knife bar 4 detachably connected between the connectors 11, a knife disc 5 slidably sleeved on the knife bar 4, and a motor 10. The motor 10 is fixedly connected to the outer side of one of the rotating plates 2, and the output shaft of the motor 10 is coaxially fixedly connected to the connected connector 11. Specifically, each tool assembly is individually equipped with a motor 10, so that each tool assembly can operate independently, the connector 11 and the knife bar 4 are detachable, and when a group of tool assemblies are in operation, other tool assemblies can be disassembled and maintained without affecting each other. The knife disc 5 can be slidably sleeved on the knife bar 4, and the position of the knife disc 5 can be adjusted as needed to obtain more knife spacing sizes.

[0026] Furthermore, if Figure 3As shown, the side of the connector 11 away from the rotating plate 2 is fixedly connected with a limiting protrusion 13, and the side wall of the connector 11 is fixedly connected with the limiting teeth 12 around the circumference. The two ends of the knife bar 4 are provided with mounting heads that match the connector 11. The mounting heads include a fixed cover 16 fixedly connected to the end of the knife bar 4 and a movable cover 15 movably connected to the fixed cover 16. The inner sides of the fixed cover 16 and the movable cover 15 are both provided with a slot 14 that matches the connector 11. The sides of the fixed cover 16 and the movable cover 15 are both fixedly connected with side ears 21, and the upper and lower side ears 21 are fixedly connected by bolts and nuts. Specifically, when the knife bar 4 is installed with the connector 11, the connector 11 is placed in the slot 14 of the fixed cover 16, and then the movable cover 15 is covered with the fixed cover 16, and the side ears 21 are fixed together by bolts and nuts, so that the mounting head is clamped on the outer side of the connector 11. At the same time, the knife bar 4 can be driven to rotate by the setting of the limiting protrusion 13 and the limiting teeth 12.

[0027] Furthermore, if Figure 6 As shown, a guard plate 3 is fixedly connected between the rotating plates 2, and the guard plate 3 is Y-shaped. Specifically, through the arrangement of the guard plate 3, when the upper cutter assembly is maintained, disassembled, or adjusted, the guard plate 3 can prevent parts from falling onto the running coil.

[0028] Furthermore, if Figure 4 , Figure 5 As shown, locking ribs 17 are symmetrically fixed on both sides of the knife bar 4, a slide groove 18 is opened on the top of the knife bar 4, a through hole matching the knife bar 4 is opened at the center of the knife disc 5, and a slider 20 with a convex cross section is fixed inside the through hole, and the slider 20 is slidably placed inside the slide groove 18, and positioning holes 19 are opened equidistantly in the slide groove 18, and the slider 20 is fixed to the positioning hole 19 by bolts. Specifically, the positioning hole 19 is a threaded hole, and the locking ribs 17 and the slide groove 18 can both limit the knife disc 5, so that the knife disc 5 can rotate with the knife bar 4, and the knife disc 5 can also move along the axial direction of the knife bar 4. After the knife disc 5 moves to the desired position, the slider 20 is fixed to the positioning hole 19 by bolts, so that the position of the knife disc 5 can be adjusted.

[0029] Furthermore, if Figure 1 As shown, one of the rotating plates 2 is also connected to a tool changing mechanism, which includes a sprocket 1 6 coaxially fixed to the rotating plate 2, a motor 1 8 fixed to the frame, a sprocket 2 9 coaxially fixed to the output shaft of the motor 1 8, and a chain 7 connected between the sprocket 1 6 and the sprocket 2 9. Specifically, the motor 1 8 drives the sprocket 2 9 to rotate, the sprocket 2 9 drives the sprocket 1 6 to rotate through the chain 7, the sprocket 1 6 drives the rotating plate 2 to rotate, and the rotating plate 2 drives all the tool assemblies to rotate, thereby changing the position of the tool assemblies.

[0030] Working principle: When the spacing of the cutter discs 5 needs to be adjusted, unscrew the bolts on the slider 20, slide the cutter disc 5 left and right to the desired position, and then fix the slider 20 and the positioning hole 19 again with the bolts to complete the adjustment of the spacing of the cutter discs 5.

[0031] By equipping each tool assembly with a motor 210, each tool assembly can operate independently without affecting each other. When disassembling the tool rod 4, it is only necessary to unscrew the bolts and nuts on the side ears 21 to separate the mounting head from the connecting head 11, and then the tool rod 4 can be removed. This is very convenient and quick, without stopping the machine and will not affect normal production.

[0032] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
