For sealing rings of different production batches, the sizes of the sealing rings are different. The diameter of the sleeve column is fixed and cannot be used for sealing rings of different sizes, which reduces the use efficiency of the device. Therefore, we need a cutting device for sealing ring production. Utility Model Content

[0029] Through the above technical solution, the limit plate 306 can be moved left and right by starting the motor 303, so that the limit plate 306 moves outward and disengages from the limit groove 307, thereby releasing the limit fixation of the mounting column 302, and then the mounting column 302 can be pulled out upward for replacement. During installation, it is only necessary to extend the new mounting column 302 into the mounting groove 301, and then extend the limit plate 306 into the limit groove 307. By setting a replaceable sleeve column, the installation of the sealing ring can select sleeve columns of different sizes according to different sizes, which is convenient for replacement and improves the use efficiency of the cutting device.

[0030] Specifically, a cutting mechanism 4 is installed on the top of the base 1 , and a moving mechanism 5 is arranged on the left side of the top of the base 1 .

[0031] Through the above technical solution, the cylinder in the cutting mechanism 4 is started to move the cutting head downward to cut the top of the sealing ring, and the moving mechanism 5 can push the bottom of the sealing ring to move, so that the position of the sealing ring can be adjusted.

[0039] Through the above technical solution, the filter screen 702 can be extended into one side of the waste bin 6 through the card slot 701, so that the filter screen 702 has a detachable effect to prevent the filter screen 702 from being blocked during long-term use, thereby affecting the normal use of the waste bin 6.

[0040] Specifically, the waste box 6 forms a snap-fit ​​structure with the connecting block 704 through the connecting groove 703 , and the shape and size of the connecting groove 703 match the shape and size of the connecting block 704 . The waste box 6 forms an elastic structure with the spring 705 and the limiting block 706 .

[0041] Through the above technical solution, the connection of the filter 702 is facilitated, and the connecting block 704 on one side of the filter 702 will extend into the connecting groove 703 for connection, and there is an elastic limiting block 706 in the connecting groove 703 to squeeze and limit, so as to prevent the filter 702 from moving, and has a certain limiting effect.

[0042] Working principle: When using the cutting device for producing the sealing ring, first, when replacing the sleeve column of the sealing ring, start the motor 303 first, the motor 303 drives the gear 304 to rotate, the gear 304 drives the rack 305 to move outward, and then the rack 305 drives the limit plate 306 to move outward, so that the limit plate 306 disengages from the limit groove 307, releases the limit fixation of the mounting column 302, and then pulls the sleeve column upward, and then extends the mounting column 302 at the bottom of the other sleeve column into the mounting groove 301, and then rotates the motor 303 in the opposite direction so that the gear 304 drives the rack 305 to move inward, and then the limit plate 306 moves inward and extends into the limit groove 307 to limit and fix the mounting column 302, completing the sealing. The replacement of the trap column is convenient and quick. When cleaning the filter 702, you only need to pull out the front end of the filter 702 by hand, so that the filter 702 is pulled out of the waste box 6 as a whole. Then the staff will deal with the blockage on the filter 702, and then re-insert one end of the filter 702 into the card slot 701 to connect with the waste box 6. At the same time, the connecting block 704 on one side of the filter 702 will extend into the connecting slot 703 for connection, and there is an elastic limit block 706 in the connecting slot 703 to squeeze and limit, so as to prevent the filter 702 from moving and achieve a certain degree of limitation. This completes all the work. The content not described in detail in this manual belongs to the existing technology known to professional and technical personnel in this field.
