[0022] Example 1

[0023] like Figure 1-3 As shown, the present application discloses a cardboard processing and cutting structure, comprising a workbench 1, a mounting frame 2 is mounted on the upper end of the workbench 1, a cylinder 3 is mounted on the bottom of the front end of the mounting frame 2, a cutting and cleaning assembly 4 is mounted on the bottom end of the cylinder 3, and the cutting and cleaning assembly 4 comprises a mounting plate 401, a cutting knife 402 is mounted in the center of the bottom of the mounting plate 401, a groove 403 is respectively provided at the front and rear ends of the cutting knife 402, a dust hood 404 is respectively mounted at the bottom end of the mounting plate 401 and at the front and rear ends of the cutting knife 402, a dust suction port 405 is respectively provided at the bottom of the dust suction hood 404 corresponding to the position of the groove 403, a dust suction pipe 406 is mounted on the air outlet end of the dust suction hood 404, a fixing member 407 is mounted on the outside of the dust suction pipe 406, the bottom end of the fixing member 407 is fixedly connected to the mounting plate 401, and a cleaning assembly is mounted on the inside of the dust suction hood 404;

[0024] The cylinder 3 drives the mounting plate 401 and the cutting knife 402 to descend to cut the cardboard. The air outlet end of the dust suction pipe 406 is connected to an exhaust fan. The dust suction pipe 406 cooperates with the dust suction hood 404 to absorb the paper scraps generated by cutting. The paper scraps between the cutting knife 402 and the cutting surface of the cardboard can be absorbed through the groove body 403.

[0025] like Figure 1 、 2 As shown in Figures 3 and 6, the bottom of the dust hood 404 is designed to be inclined, and the bottom end of the inclined surface is fixedly connected to the cutting knife 402. Through the inclined surface at the bottom of the dust hood 404, the paper scraps generated during cutting can be moved along the inclined surface to the dust pipe 406 for discharge during vacuuming.

[0026] like Figure 3-6As shown, the cleaning assembly includes a fixing frame 408, the bottom end of the fixing frame 408 is fixedly connected to the mounting plate 401, a fixing bar 409 is installed at the bottom end of the inner side of the fixing frame 408, a disc 410 is installed at the bottom end of the fixing bar 409, a cleaning rod 412 is installed on the outer side of the disc 410, a spring 411 is sleeved between the outer side of the fixing bar 409 and the inner side of the cleaning rod 412 and the upper end of the disc 410, a rack 413 is installed on the outer side of the cleaning rod 412, a partially toothed gear 414 is installed on the outer side of the rack 413, and a transmission rod 415 is installed on both sides of the partially toothed gear 414. A motor 416 is installed on the side wall of 04, and the output end of the motor 416 is fixedly connected to the end of the transmission rod 415. The motor 416 drives the transmission rod 415 to rotate, and the transmission rod 415 drives the partial tooth gear 414 to rotate. The partial tooth gear 414 rotates one circle to drive the rack 413 and the cleaning rod 412 to descend. The bottom end of the descending cleaning rod 412 passes through the dust suction port 405 to clean the paper scraps that block the dust suction port 405 of the cutting and cleaning component 4. When the teeth on the partial tooth gear 414 are not engaged with the rack 413, the fixing bar 409 cooperates with the disc 410 and the spring 411 to drive the cleaning rod 412 to reset.

[0027] like Figure 4-5 As shown, the cross section of the fixing bar 409 is designed to be square, which can limit the position of the cleaning rod 412 when it moves up and down, thereby preventing the rack 413 and the partial tooth gear 414 from being misaligned.

[0028] like Figure 3-6 As shown, the upper and lower ends of the cleaning rod 412 are both hemispherical in design. The cleaning rod 412 moves in the groove body 403, and air vents 417 are opened at the upper and lower ends of the mounting plate 401. The top of the cleaning rod 412 is located in the air vent 417 in the initial state. The cleaning rod 412 is in the air vent 417 in the initial state and can close the air vent 417. When the cleaning rod 412 is lowered for cleaning, the upper part of the cleaning rod 412 moves out of the air vent 417, and the lower part of the cleaning rod 412 closes the dust suction port 405 and the groove body 403, and the external air is sucked into the dust suction hood 404 through the air vent 417 to avoid deformation of the dust suction tube 406.

[0029] The standard parts used in this utility model can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0030] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0031] The implementation principle of a cardboard processing and cutting structure in the embodiment of the present application is as follows:

[0032] When in use, the cardboard is placed at a specified position on the workbench 1, the cylinder 3 drives the cutting and cleaning component 4 to descend, the cutting knife 402 contacts the cardboard, and cuts the cardboard. Paper scraps are generated during cutting, and the exhaust fan is started at the same time, and suction is generated through the air outlet end of the dust suction pipe 406. The dust suction pipe 406 cooperates with the dust suction cover 404 to suck dust through the dust suction port 405. The paper scraps generated during the cutting process are guided to the bottom of the dust suction cover 404 by the suction force. Since the bottom of the dust suction cover 404 is inclined, the paper scraps move along the inclined surface to the connection between the dust suction pipe 406 and the dust suction cover 404 and are discharged. The paper scraps on the cut surface of the cardboard can be cleaned through the groove 403 set on the cutting knife 402. When the dust suction port 405 is blocked, the motor 416 drives the transmission rod 415 to rotate, thereby driving the partial tooth gear 414 to rotate. When the partial gear When the teeth on the gear 414 mesh with the rack 413, the rack 413 and the cleaning rod 412 begin to descend, and the hemispherical bottom of the cleaning rod 412 passes through the dust suction port 405 to clean the paper scraps blocked in the dust suction port 405. While the cleaning rod 412 descends to clean, its upper end moves out from the vent 417, and the lower end seals the dust suction port 405 and the groove body 403. In this way, external air is sucked into the dust suction cover 404 through the vent 417, ensuring the air circulation in the dust suction pipe 406 and avoiding the deformation of the dust suction pipe 406 caused by the blockage of the dust suction port 405. When the partially toothed gear 414 rotates to no longer mesh with the rack 413, the fixing bar 409 cooperates with the disc 410 to recover through the deformation of the spring 411, driving the cleaning rod 412 to return to its initial state, and the top end closes the vent 417 again.
