Description
Technical Field
[0001] The utility model belongs to the field of molding paper processing devices, in particular to a plastic molding paper die-cutting device. Background Art
[0002] In traditional technology, only a pair of bearings are set at the die-cutting roller. When running, the roller will shake slightly up and down, affecting the punching effect; the conventional gear set drives the die-cutting roller and the die-cutting roller to operate, and the die-cutting roller and the die-cutting roller will not be tightly engaged, resulting in the plastic sheet being unable to be completely cut off; after the die-cutting roller and the die-cutting roller punch, there is no secondary waste cleaning, and a small amount of laminating waste remains on the paper strip. Utility Model Content
[0003] In order to solve the above problems, the utility model provides a plastic molding paper die-cutting device.
[0004] The plastic molding paper die-cutting device comprises a die-cutting device mounting plate, a device housing assembly, a light roller clamping block, a knife roller assembly, a light roller assembly, a waste recovery port, a second scraper, a reduction motor and a paper path waste cleaning assembly, and is characterized in that the paper path waste cleaning assembly comprises a waste cleaning shaft mounting seat, a waste cleaning shaft, a scraper mounting seat, a scraper mounting rod and a first scraper, the waste cleaning shaft mounting seat is located in the paper output direction of the device housing assembly, the waste cleaning shaft mounting seat is mounted with a waste cleaning shaft, a scraper mounting seat is provided next to the waste cleaning shaft mounting seat, a scraper mounting seat is mounted with a scraper mounting rod, a first scraper is provided on the scraper mounting rod, the plastic molding paper is bent by the waste cleaning shaft, and the first scraper fits the plastic molding paper surface at the bending portion of the plastic molding paper.
[0005] Furthermore, the device shell assembly includes a shell cover, a shell body and a shell bottom plate. The shell cover is provided with a clamping screw, which is in contact with the knife roller assembly. The shell bottom plate is provided with a waste recovery port, and a second scraper is provided in the waste recovery port. The second scraper is located directly below the optical roller assembly.
[0006] Furthermore, the knife roller assembly includes a driven gear, a bearing, a die-cutting knife roller and a bearing clamping block. There are two pairs of bearings, one pair of bearings is installed in the U-groove position of the shell body, and one pair of bearings is installed in the bearing clamping block. The die-cutting knife roller is installed in the bearing, and the driven wheel is installed on the die-cutting knife roller.
[0007] Furthermore, the optical roller assembly includes a driving gear, a die-cutting optical roller, a negative pressure end cover and an active roller bearing end cover, the driving gear is installed on the die-cutting optical roller, the negative pressure end cover is a convex structure, and the convex part of the negative pressure end cover is provided with a semicircular negative pressure cavity and a blowing port; the cavity in the center of the die-cutting optical roller is a concave structure, and the convex part of the negative pressure end cover is installed in the concave cavity in the center of the die-cutting optical roller, and a hollow channel is provided on the die-cutting optical roller at the contact position between the surface of the die-cutting optical roller and the die-cutting knife roller cutter, and the hollow channel is connected to the cavity in the center of the die-cutting optical roller.
[0008] Furthermore, a reduction motor is installed on the die-cutting device mounting plate, the reduction motor is connected to the die-cutting light roller, the driving gear and the driven gear are meshed, and the driving gear and the driven gear are negative displacement gears.
[0009] When in use, the plastic molding paper passes between the die-cutting roller and the die-cutting roller. After punching is completed, the waste is adsorbed on the die-cutting roller through the negative pressure suction in the negative pressure end cover. After the waste rotates half a circle with the die-cutting roller, the waste is blown into the waste recovery port through the blowing port under the negative pressure end cover. At the same time, the second scraper installed in the waste recovery port will scrape the waste remaining on the die-cutting roller and drop it into the waste recovery port. The clamping screw is used to clamp the die-cutting roller during work. The plastic molding paper with holes punched changes its paper path through the waste cleaning shaft. The plastic molding paper is bent when passing through the waste cleaning shaft, causing the waste originally attached to the molding paper to tilt up and create a gap between the molding paper and the first scraper. The small amount of waste remaining on the plastic molding paper is then scraped off.
[0010] The utility model has the following beneficial effects: first, the negative displacement gear transmission enables the die-cutting roller to fit more closely with the die-cutting roller when pressed downward, thereby avoiding the situation that the plastic forming paper cannot be completely cut off when punching holes; second, it has a secondary waste cleaning effect; third, when the clamping screw presses the bearing clamping block downward, the arrangement of the two pairs of bearings makes the die-cutting roller more stable and reliable during operation.
