9. The cutting method of the fixed-length cutting device for manufacturing the automobile window adhesive tape is characterized by comprising the following steps of:
the method comprises the following steps: firstly, guiding one end of an automobile window adhesive tape outside an emptying roller (4) to a position between a leading-in roller (10) and a cutting table (8) through a first guide roller (6) and a second guide roller (7), starting a motor (17) to work, driving a belt pulley (18) to rotate by the motor (17), driving the leading-in roller (10) and a leading-out roller (11) to rotate by the belt pulley (18) through a connecting belt (19), when the leading-in roller (10) rotates, conveying the automobile window adhesive tape to the direction of the leading-out roller (11) by matching with a lubricating and rotating roller (20), when the automobile window adhesive tape enters a position between the leading-out roller (11) and the cutting table (8) and extends out for a certain length, stopping the motor (17) to work, and determining the position needing to be cut;
step two: when the automobile window adhesive tape moves on the cutting table (8), the automobile window adhesive tape passes through a position between the first positioning block (1403) and the second positioning block (1404), and the opposite surfaces of the first positioning block (1403) and the second positioning block (1404) are combined into a convex shape, so that the automobile window adhesive tape is limited at the top, the bottom and the side surfaces of the first positioning block (1403) and the second positioning block (1404), the automobile window adhesive tape is kept to move linearly, and after a nut (1408) is loosened by people, the first positioning block (1403) and the second positioning block (1404) can slide through the sliding groove (1406) and slide to a proper position, and then the nut (1408) is screwed, so that the positioning machines of the first positioning block (1403) and the second positioning block (1404) can be adjusted and fixed;
step three: the air cylinder (13) works, an output shaft of the air cylinder pushes the cutting knife (15) to press downwards, meanwhile, the cutting knife (15) drives the limiting column (1602) to move downwards, when the limiting column (1602) contacts the pressing seat (1601), the pressing seat (1601) is pressed downwards through the guide column (1603), the compression spring (1604) contracts, the pressing seat (1601) is pressed on the upper portion of the automobile window rubber strip, at the moment, the cutting knife (15) continues to press downwards, the automobile window rubber strip is cut off by matching with the cutting groove (23), cutting work is completed, and scraps generated by cutting fall into the scrap collecting drawer (21) through the cutting groove (23);
step four: after the cutting, cylinder (13) drive cutting knife (15) and reset, lose pressure after, spring (1604) expansion pushes and compresses tightly seat (1601) and reset, then motor (17) continue to work, carry car window adhesive tape, the circulation is accomplished work.
