In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0021] like Figure 1-4 As shown, a slitting machine knife seat assembly structure described in this embodiment includes an I-shaped rail 1, a travel motor 2, a hanging beam 3 and a knife seat roller group; the I-shaped rail 1 is installed on the slitting machine frame as a main load-bearing component, a slide rail 4 and a rack 5 are arranged in parallel on the I-shaped rail 1, a gear matched with the rack 5 is arranged on the output shaft of the travel motor 2, the hanging beam 3 is fixedly connected to the travel motor 2 and has a slider 6 matched with the slide rail 4, and the hanging beam 3 is driven to translate by the travel motor 2;

[0022] The knife base roller group includes a driving roller 7, a knife roller 8 and a nylon knife base 9. The driving roller 7 is driven by a motor. The driving roller 7 includes a shaft head 10 and a shaft body 11. The shaft body 11 has a plurality of paper scraps giving way sections 12. The diameter of the paper scraps giving way sections 12 is smaller than the diameter of the shaft body 11. The paper scraps generated by cutting can be temporarily attached to the circumference of the paper scraps giving way sections 12 to avoid a large amount of paper scraps from being present on the circumference of the shaft body 11 for a long time, thereby causing extrusion holes and damage to the corrugated cardboard. The knife roller 8 can slide axially at the same time. The shaft sleeve is arranged on the driving roller 7, and a key 13 is arranged on the driving roller 7. A keyway and a through hole groove 14 are arranged on the inner ring of the knife roller 8. The keyway cooperates with the key 13, so that the driving roller 7 can drive the knife roller 8 to rotate, and the through hole groove 14 can allow fine paper scraps to pass through the knife roller 8. The nylon knife seat 9 is fixed on the hanging beam 3 by a plurality of bolts. When the hanging beam 3 moves horizontally, the nylon knife seat 9 is driven to move horizontally, and the knife roller 8 is rotatably installed in the nylon knife seat 9; a chip collecting and scraping mechanism is also arranged on the nylon knife seat 9;

[0023] The chip collecting and scraping mechanism includes an annular groove 15 provided on the nylon knife seat 9 and a scraping slider 16 provided in the annular groove 15. A first magnet 17 is provided in the scraping slider 16, and a second magnet 18 is provided in the knife roller 8. The first magnet 17 and the second magnet 18 are oppositely polarized to each other, so as to maintain the attraction of the second magnet 18 to the first magnet 17. Preferably, the number of the second magnets 18 is multiple, and the multiple second magnets 18 are evenly distributed along the circumference of the cross section of the knife roller 8. The application of multiple second magnets 18 can shorten the pause time of the scraping slider 16. When the first magnet 17 is decoupled from a second magnet 18, the next second magnet 18 can try to attract the drive as soon as possible. The first magnet 17; at least one chip collecting groove 19 is also provided in the annular groove 15, preferably two chip collecting grooves 19 are both facing forward for easy cleaning, and the opening length of the chip collecting groove 19 is less than the length of the scraper slider 16, so that the scraper slider 16 can better pass over the chip collecting groove 19 to avoid being stuck; the nylon knife holder 9 is also provided with a negative pressure suction chamber 20 cooperating with the annular groove 15, and a plurality of air holes 21 connected to the negative pressure suction chamber 20 are evenly distributed on the inner side of the annular groove 15; the nylon knife holder 9 is also provided with a suction pipe connecting nozzle 22, which is connected to the negative pressure suction chamber 20 through a flow channel, and the suction pipe connecting nozzle 22 is connected to the induced draft fan through a hose.

[0024] The assembly structure of the scraper slider 16 and the nylon knife seat 9 is as follows: an annular guide groove 23 is correspondingly arranged on the front and rear wall surfaces inside the annular groove 15, and guide sliders 24 matching the annular guide groove 23 are respectively integrally arranged on the front and rear sides of the scraper slider 16; the scraper slider 16 is a self-lubricating slider, and the material of the self-lubricating slider is polytetrafluoroethylene. The surface energy of polytetrafluoroethylene is low and the friction coefficient is very small, so that the scraper slider 16 can slide smoothly in the annular groove 15.

[0025] The working principle of this embodiment is:

[0026] According to the production process requirements, the travel motor 2 is controlled to drive the nylon knife seat 9 and the knife roller 8 to the appropriate position on the driving roller 7, that is, the cutting line position is determined, the travel motor 2 is stopped, and the driving roller 7 is started. The driving roller 7 drives the knife roller 8 to rotate and cut the corrugated cardboard. The debris generated by the cutting is attracted into the annular groove 15 by the air holes 21 in the annular groove 15, and the scraper slider 16 rotates in the annular groove 15 to push the debris into the chip collecting groove 19. After the longitudinal cutting machine has been running for a period of time, the debris in the chip collecting groove 19 can be cleaned. Compared with the prior art, the chip collecting and scraping mechanism is used in this embodiment to effectively collect the corrugated cardboard debris to avoid affecting the accuracy of the subsequent pressing line cutting of the cardboard, and effectively ensure the neatness of the cutting edge of the corrugated cardboard and the qualified rate of cardboard cutting.

[0027] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific uses.
