[0042] Working principle:

[0043] like Figure 1-6 and Figure 8-9As shown, the staff first places the material to be cut on the conveying plate 2, and places the short side of the F-shaped rod 721 above the material. The F-shaped rod 721 drives the slide rail 771 and the rotating shaft 72 to move, and adjusts the height of the disc 73 and the push rod 2 773; then the staff adjusts the sliding distance of the support plate 1 52 on the electromagnetic slide rail 51 according to the length of the cut, and starts the cylinder 53 after reaching the appropriate distance. The cylinder 53 extends out of the output end and presses the support plate 2 54 downward, so that the rotating plate 55 fits the material. When the material is in the middle of the rotating plate 55, the rotating plate 55 and the material can be stuck to the rotating plate 55. Since the rotating plate 55 is crescent-shaped, the rotating plate 55 The two ends of the rotating plate 55 press the material so that it cannot slide to the sides. If the size of the material is large and cannot be clamped by the curved surface of the rotating plate 55, the middle part of the material will squeeze the rotating plate 55 as a whole toward the supporting plate 2 54 and compress the compression spring 551 and the spring 1 56, and the end of the material contacts one end of the other rotating plate 55, so that one end of the other rotating plate 55 compresses the spring 1 56. Since the middle part is not compressed, the middle part will not retract into the supporting plate 2 54, and the other end of the rotating plate 55 will rotate toward the direction of the material and clamp the material, so that it will not cause the problem of different cut-off lengths due to tilting left and right, and the device can be suitable for materials of different sizes and shapes.

[0044] like Figure 1 and Figure 5-9 As shown, after the material is cut by the flat cutting device 3, the short side of the push rod 2 773 is above the material, the staff starts the motor 778, drives the fixed rod 777 to rotate and drives the irregular disk 77 to rotate, and the irregular disk 77 drives the cylinder 1 75 to slide in the groove 74. When the cylinder 1 75 slides out of the strip groove of the groove 74, the spring 3 775 pulls the slider 1 772 to move toward the fixed block and drives the slider 774 to move synchronously. The slider 774 drives the slider 2 7741 to move synchronously. The slider 2 7741 drives the cylinder 2 76 to slide in other strip grooves in the groove 74. At the same time, the slider 1 772 drives the push rod 2 773 to move toward the disk 73, and the push rod 2 773 drives The cut materials slide on the conveyor plate 2, reducing the accumulation of materials on the conveyor plate 2 and the workload of the staff, and slide into the storage box 65 for storage; then with the continuous rotation of the irregular disk 77, the cylinder 1 75 is driven to slide into the strip groove of the groove 74. At this time, the cylinder 2 76 slides out of the other strip grooves in the groove 74, driving the slide bar 774 to move toward the fuselage 1 in the fixed block 2 776, and pushing the slider 1 772 and the push rod 2 773 to move synchronously while stretching the spring 3 775. The push rod 2 773 continues to slide to the top of the material to press the material to prevent the harder materials from bouncing around when being cut, thereby causing harm to the staff.

[0045] like Figure 1-2 and Figure 7 As shown in the figure, when changing materials and switching the cutter, it is only necessary to completely retract the horizontal cutting device 3 upwards, and the output end of the horizontal cutting device 3 pulls the rack 2 45, the rack 2 45 drives the gear 44 to rotate, and the gear 44 drives the rack 1 43 to move downwards, and drives the strip plate 42 to move synchronously into the machine body 1, exposing the strip hole 41, so as to facilitate the operation of the rotary cutting device 4, and reduce the time required for the staff to replace different parts according to different materials; and when the staff moves the rotary cutting device 4 to the bottom of the horizontal cutting device 3, push Rod 1 63 pushes the previous storage box 65 to one side, and the staff selects a storage box 65 of appropriate size and places it on the end of the conveying plate 2, and pushes one end of the push rod 1 63, so that the push rod 1 63 compresses the spring 2 62, and at the same time, the fixing plate 64 is inserted into the corresponding transverse groove 641, limiting the position of the storage box 65 and preventing the push rod 1 63 from pushing the storage box 65 away from the position. When the rotary cutting device 4 is cutting the material, the push rod 1 63 can only slide on the side of the storage box 65 and will not push the storage box 65 away from its original position.
