However, in the production process of rubber seals, the edges of newly produced seals often have burrs. In order to ensure the appearance quality and dimensional accuracy of the seals, these burrs must be polished and trimmed. In order to solve this problem, various rubber seal trimming devices have emerged, which greatly improve the efficiency of seal trimming.

Under the pressure of the pressure roller 409 and the action of the trimming knife 410, the rotating seal can be trimmed to ensure the trimming quality, and under the action of the arc groove 407, the telescopic length of the moving rod 1 403 and the moving rod 2 404 can be adjusted as a whole, so as to achieve the trimming of seals of different sizes.

[0032] The working principle of the trimming mechanism 4 is as follows: by rotating the rotating disk 406, and with the cooperation of the arc groove 407 and the limiting column 1 405, the moving rod 1 403 and the moving rod 2 404 are moved, driving the pressure roller 409 and the trimming knife 410 to move above the rubber seal placement groove 305, so as to trim the seals of different sizes, and under the pressure of the pressure roller 409, the rotating seal is trimmed to ensure the quality of the trimming.

[0037] In actual application, the staff places the untrimmed seal in the rubber seal placement groove 305, rotates the seal to the bottom of the trimming mechanism 4 by rotating the output shaft of the motor 1 301 in the rotating mechanism 3, and then moves the trimming mechanism 4 to the position just in contact with the seal through the adjusting mechanism 5, and then rotates the output shaft of the motor 2 307 in the rotating mechanism 3 to achieve trimming of the seal by the trimming mechanism 4. After the trimming is completed, the adjusting mechanism 5 is started again to drive the trimming mechanism 4 to move to a position away from the trimmed seal, and the output shaft of the motor 1 301 in the rotating mechanism 3 is rotated again to move the trimmed component rack 304 to the side of the staff, who takes away the trimmed seal and cleans up the debris, and then puts the untrimmed seal into the rubber seal placement groove 305 again, thereby achieving trimming and placing the seal at the same time, thereby improving the trimming efficiency.
