Description

Technical Field

[0001] The utility model relates to a cutting device, in particular to a release base paper cutting device, belonging to the technical field of cutting devices. Background Art

[0002] Release paper is a special anti-sticking paper, which is mainly used to prevent the prepreg from sticking and protect the prepreg from pollution. It is made of paper coated with anti-sticking material. Its models are distinguished by the material, thickness, elongation, single and double sides. Release paper needs to be cut in the production process to cut the wide base paper into a certain width. During the cutting process, the distance between the two guide wheels on the two rotating shafts at the feed point should be adjusted according to the width of the base paper to guide the base paper feed point.

[0003] However, the traditional adjustment method only rotates two guide wheels connected on the feed shaft. When adjusting, it is necessary to manually move the guide wheels on the two shafts in turn to adjust the distance between the guide wheels to guide the base paper. The guide wheels are only fixed by the friction between the shafts and are prone to sliding left and right after long-term use, resulting in poor positioning function. Utility Model Content

Since the threads at both ends of the first screw rod 401 are opposite, the first screw rod 401 drives the two first sliders 404 to move in opposite directions. The first slider 404 drives the first guide wheel 405 and the second guide wheel 406 to slide on the first rotating shaft 2 and the second rotating shaft 3 respectively, so that the spacing between the two first guide wheels 405 and the spacing between the two second guide wheels 406 are adjusted at the same time, so that the two guide wheels on the two rotating shafts can both position and guide the release base paper. The operation is simple and flexible, and the work efficiency is improved. The first guide wheel 405 and the second guide wheel 406 are both rotatably connected to the first slider 404, which increases the stability of the first guide wheel 405 and the second guide wheel 406, and avoids slipping to both sides during work, causing the base paper to deviate from the track and affect the cutting work.

[0021] As a technical optimization scheme of the utility model, the installation position of the first rotating shaft 2 is higher than the installation position of the second rotating shaft 3, and the first sliding block 404 is in a "U"-shaped structure; the release paper is passed through the bottom end of the first rotating shaft 2 and then through the top end of the second rotating shaft 3, so that the bottom surface of the first rotating shaft 2 is in contact with the top surface of the release paper, and the top surface of the second rotating shaft 3 is in contact with the bottom surface of the release paper, which can guide the release paper. When the release paper moves toward the direction of the cutting structure 8, it drives the first rotating shaft 2 and the second rotating shaft 3 to rotate. In the process of the first guide wheel 405 and the second guide wheel 406 in contact with the release paper, the release paper drives the first guide wheel 405 and the second guide wheel 406 to rotate, thereby reducing the friction between the release paper and the guide wheels and reducing damage to the release paper.

The driving roller 9 is arranged in parallel with the driven roller 5. A limiting structure 6 is installed on both sides of the driven roller 5. The limiting structure 6 includes a sliding frame 602. Two sliding frames 602 are symmetrically arranged on the operating table 1. A second slider 604 is slidably connected inside the sliding frame 602, and a driven roller 5 is rotatably arranged between the two second sliders 604; a second screw rod 601 is rotatably connected inside the sliding frame 602, and the bottom end of the second screw rod 601 is threadedly connected to the second slider 604, and the top end of the second screw rod 601 is slidably connected to the second slider A second rotating rod 603 is connected; according to the thickness of the release paper, the second rotating rod 603 is rotated, and the second rotating rod 603 drives the second screw rod 601 to rotate. The second screw rod 601 threadably drives the second slider 604 to slide up and down inside the slide frame 602, and the second slider 604 drives the driven roller 5 to move until the bottom surface of the driven roller 5 contacts the top surface of the release paper, and then the motor is started, and the motor drives the driving roller 9 to rotate, and the driving roller 9 drives the release paper to move forward, and at the same time generates friction with the driven roller 5 to drive the driven roller 5 to rotate, thereby completing the transportation and further positioning of the release paper, so that the release paper is always kept in the middle position of the operating table 1, which is convenient for the cutting structure 8 to cut the release paper.

Since the threads at both ends of the first screw rod 401 are opposite, the first screw rod 401 drives the two first sliders 404 to move in opposite directions, and the first slider 404 drives the first guide wheel 405 and the second guide wheel 406 to slide on the first rotating shaft 2 and the second rotating shaft 3 respectively, so that the spacing between the two first guide wheels 405 and the spacing between the two second guide wheels 406 are adjusted at the same time, so that the two guide wheels on the two rotating shafts are both aligned with the release paper. The paper positioning guide is simple and flexible to operate, which improves the work efficiency. The first guide wheel 405 and the second guide wheel 406 are both rotatably connected to the first slider 404, which increases the stability of the first guide wheel 405 and the second guide wheel 406, and prevents them from slipping to both sides during work, causing the base paper to deviate from the track and affect the cutting work; the release base paper passes through the bottom end of the first rotating shaft 2 and then through the top end of the second rotating shaft 3, so that the bottom surface of the first rotating shaft 2 is in conflict with the top surface of the release base paper, and the top surface of the second rotating shaft 3 is in conflict with the bottom surface of the release base paper.
