Detailed implementation manners

[0020] To make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific implementation manners.

[0021] As Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a cutting device with a quick disassembly and installation function includes a bottom plate 1. A bracket 2 is fixedly connected to the bottom plate 1. A cylinder 3 is fixedly connected to the bracket 2. A connecting frame 4 is fixedly connected to the output shaft of the cylinder 3. A slider 7 is movably installed in the connecting frame 4. A cutting knife 5 is fixedly connected to the bottom surface of the slider 7. A number of fixing grooves 8 are formed in the slider 7. A rubber gasket 10 is fixedly connected in the fixing grooves 8. On both sides of the cylinder 3 on the connecting frame 4, a first guide rod 13 is fixedly connected. A movable block 15 is movably installed on the first guide rod 13. A fixing rod 14 is fixedly connected to the bottom surface of the movable block 15. On the bracket 2 above the position of the movable block 15, a positioning rod 16 is fixedly connected. A chute 6 is formed in the connecting frame 4. The slider 7 is movably installed in the chute 6 of the connecting frame 4. A rubber block 11 is fixedly connected to the side surface of the rubber gasket 10. A fixing screw hole 9 is formed in the slider 7 on the side of the fixing groove 8. The fixing groove 8 and the fixing screw hole 9 are interconnected. A fixing bolt 12 is movably installed on the rubber block 11 and is fixedly connected in the fixing screw hole 9. A through hole is provided on the connecting frame 4 corresponding to the position of the rubber gasket 10. The fixing rod 14 passes through the connecting frame 4 and is movably installed with the rubber gasket 10. The first guide rod 13 is movably installed with the bracket 2. The lower end of the positioning rod 16 is fixedly connected with a rubber head 17, and the rubber head 17 is located above the movable block 15. An insertion hole 18 is formed in the movable block 15. Slide the slider 7 into the chute 6 of the connecting frame 4, and then retract the output shaft of the cylinder 3 upward, so that the connecting frame 4 and the first guide rod 13 move upward, and the movable block 15 and the fixing rod 14 move upward synchronously. When the movable block 15 contacts the rubber head 17 below the positioning rod 16, the movable block 15 is blocked from moving upward by the positioning rod 16, so that the fixing rod 14 gradually inserts into the connecting frame 4 and the slider 7. The fixing rod 14 is thinner at the bottom and thicker at the top. The fixing rod 14 inserts into the through hole of the connecting frame 4 and passes through the rubber gasket 10, so that the fixing rod 14 is fixedly connected with the slider 7, thereby fixedly installing the cutting knife 5 fixedly connected below the slider 7.

[0022] As Figure 1 and Figure 4 shown, a positioning frame 19 is fixedly connected to the side of the bracket 2 at the position of the movable block 15. A plug rod 21 is movably installed on the positioning frame 19. A movable hole 20 is formed in the positioning frame 19. The plug rod 21 is movably installed in the insertion hole 18. Limit plates 22 are fixedly connected to both ends of the plug rod 21. The plug rod 21 is movably installed in the insertion hole 18. Reset the output shaft of the cylinder 3. The plug rod 21 is exactly located on the side of the insertion hole 18. The plug rod 21 moves to the side and inserts into the insertion hole 18. Then extend the output shaft of the cylinder 3 downward. Since the movable block 15 is restricted, the fixing rod 14 is pulled out. Then slide the slider 7 out of the chute 6, so that the cutting knife 5 is disassembled. During the installation and disassembly of the cutting knife 5, the cylinder 3 in the cutting device can be used to save manpower and is convenient to use.

[0023] It should be noted that the present utility model is a cutting device with the functions of quick disassembly and installation. The slider 7 is slidably installed in the chute 6 of the connecting frame 4. One end of the chute 6 is communicated with the outside, and the other end is closed. When the slider 7 moves to the other end of the chute 6, the through hole on the connecting frame 4 coincides with the center of the rubber gasket 10. Then, the output shaft of the cylinder 3 is contracted upward, so that the connecting frame 4 and the first guide rod 13 move upward. The movable block 15 and the fixed rod 14 on the first guide rod 13 move upward synchronously. When the movable block 15 contacts the rubber head 17 below the positioning rod 16, as the connecting frame 4 continues to move upward, the movable block 15 is blocked by the positioning rod 16, so that the fixed rod 14 moves downward, and then gradually inserts into the through hole of the connecting frame 4 and passes through the rubber gasket 10. The rubber gasket 10 is located in the slider 7. The rubber gasket 10 is used to increase the friction force and fill the gap between the fixed rod 14 and the slider 7, so that the fixed rod 14 is fixedly connected to the slider 7, and thus the cutting knife 5 fixedly connected below the slider 7 is fixedly installed. After the installation is completed, when the output shaft of the cylinder 3 extends, the structures such as the connecting frame 4, the slider 7, and the fixed rod 14 move downward synchronously. When the cutting knife 5 finishes working, the output shaft of the cylinder 3 contracts, and the movable block 15 rises synchronously with the connecting frame 4. If the movable block 15 becomes loose and moves upward a certain distance, during the upward movement of the connecting frame 4, the movable block 15 contacts the rubber head 17 of the positioning rod 16 again, and the fixed rod 14 is pressed downward again by the positioning rod 16, so as to re-reinforce the fixed rod 14, making the fixed rod 14 not easy to loosen and the installation effect more stable. When disassembly is required, after the output shaft of the cylinder 3 is reset and contracted, the insertion rod 21 is exactly located at the side position of the movable block 15. The insertion rod 21 moves to the side and inserts into the insertion hole 18 of the movable block 15. Then, the output shaft of the cylinder 3 extends downward. Since the movable block 15 is restricted, the fixed rod 14 gradually pulls out from the slider 7 and the connecting frame 4. When the fixed rod 14 is pulled out from the connecting frame 4, the cylinder 3 is stopped, and then the slider 7 is slid out of the chute 6, so that the cutting knife 5 is disassembled.
