Description

Technical Field

[0001] The present invention relates to a paper cutting device, specifically a paper cutting device for paper product processing, belonging to the technical field of paper cutting devices. Background Art

[0002] Paper cutting is one of the important links in the processing and production of paper products. This process mainly cuts semi-finished paper or paper products into products of the same specification, and can ensure the overall flatness and smoothness of the paper products to meet various printing, packaging and other requirements. Paper cutting devices are widely used in various enterprises such as paper mills and printing factories, and can be used for the processing of single-sheet paper and the shaping of printed products, and can also be used for the cutting of non-paper materials such as PS plates, leather, and hard plastics.

[0003] A Chinese patent with the patent name of an efficient circular paper cutting device (publication number: CN116638578A) discloses an efficient cutting device technology. By designing the structure of the support turntable and the pressing turntable, the paper to be cut can be quickly positioned and clamped rotatably on the frame. The whole stack of rotating paper is cut by the blade of the paper cutter to form circular paper. Through the up-and-down reciprocating movement of the paper cutter and the dovetail groove arranged on the cutter surface of the paper cutter, the grinding of the cutting edge of the circular paper is realized. However, although this device can efficiently cut the whole stack of paper into circles, since it only uses the support turntable and the support plate to support the paper products, and the support turntable is the same as the processing table of the traditional paper cutting device and does not have a lifting function, when rotating the flexible paper products, due to the influence of friction, the paper products are prone to the problem of edge folding. Moreover, the position of its paper cutter is relatively fixed. Although it can move up and down reciprocally, the cutting operation mainly relies on the power of the rotation of the paper products, resulting in poor cutting effect and easy generation of a large number of burrs.

[0004] A Chinese patent with the patent name of a paper cutting mechanism of a paper cutting machine (publication number: CN116551753A) discloses a paper cutting mechanism technology. However, although this mechanism can realize the cutting of paper products by using the inclined knife body in cooperation with the up-and-down reciprocating movement and adds relevant vibration structures to the knife body to improve the cutting effect, the movement mode of the cutting knife is still the same as that of the traditional paper cutting device, and the vibration device needs to be synchronized during the paper cutting process, increasing the use cost of the paper cutting mechanism.

Then, the guide plate 701 is used to guide the cutting waste into the guide frame 704 for centralized recovery, without the need for manual collection.

[0084] After one side of the paper product is cut, the first hydraulic cylinder 305 drives the whole cutting tool holder 301 to reset, and the third hydraulic cylinder 601 drives the whole pressing paper plate frame 602 to reset. Then, the lead screw module 201 is used in cooperation with the connecting plate frame 202 to drive the back-pushing and correcting plate frame 204 to move. The moving back-pushing and correcting plate frame 204 pushes the paper product in the direction of the pushing plate frame 203, so as to push the residual paper waste on the surface of the processing table 102 into the guide frame 704.

[0085] When it is necessary to cut different edges of the paper product, the screw rod module 201 is used to drive the back-pushing and correcting plate frame 204 to reset, and another set of screw rod modules 201 is used to drive the pushing plate frame 203 to move. The moving pushing plate frame 203 pushes the paper product into the upper box frame 103 again and makes it located above the external tooth turntable 404. Then, the screw rod module 201 is used to drive the pushing plate frame 203 to reset. Then, the piston rod of the third hydraulic cylinder 601 cooperates with the pressure sensor 81 to drive the pressing plate frame 602 to move downward as a whole, so that the circular slide plate 604 drives the second disc 606 to initially extrude the surface of the paper product. Then, the piston rod of the second hydraulic cylinder 511 drives the switching box frame 512 to move. The moving switching box frame 512 drives the two internal tooth rings 513 to move, so that while one internal tooth ring 513 is separated from the first gear 503, the other internal tooth ring 513 meshes with the third gear 507. Then, the output shaft of the reduction motor 402 drives the second gear 504 to rotate. The rotating second gear 504 uses one internal tooth ring 513 to drive the other internal tooth ring 513 to rotate through the synchronous belt 514. The other rotating internal tooth ring 513 drives the threaded column 506 to rotate in cooperation with the third gear 507. The rotating threaded column 506 drives the internal threaded sleeve 505 to move by means of the thread. The moving internal threaded sleeve 505 drives the first disc 405 and the external tooth turntable 404 to move upward, so as to lift the paper product and, at the same time, use the paper product to extrude the bottom of the second disc 606, so that the second disc 606 and the circular slide plate 604 drive the spring 605 to be compressed under the action of pressure, so as to use the compressed spring 605 to cooperate with the circular slide plate 604 and the second disc 606 to provide a continuously downward thrust for the surface of the paper product to ensure its stability during rotation. When it is necessary to rotate the paper product, the piston rod of the second hydraulic cylinder 511 drives the switching box frame 512 to reset as a whole, so that while one internal tooth ring 513 meshes with the first gear 503 and the second gear 504, the other internal tooth ring 513 is separated from the third gear 507. Then, the output shaft of the reduction motor 402 drives the second gear 504 to rotate. The rotating second gear 504 drives the first gear 503 to rotate by means of the internal tooth ring 513. The rotating first gear 503 drives the tooth column 406 to rotate by means of the drive shaft 407. The rotating tooth column 406 drives the external tooth turntable 404 to rotate. The rotating external tooth turntable 404 drives the paper product to rotate so as to adjust the position of the paper product in the upper box frame 103.

[0086] After the rotation operation of the paper product is completed, the rotation drive mechanism 4 and the lifting and switching component 5 are used to drive the paper product to reset. During the reset process of the paper product, the compressed circular slide plate 604 is used to drive the circular slide plate 604 and the second disc 606 to move along with the paper product to ensure the stability during its reset process. After the paper product is reset, the third hydraulic cylinder 601 is used to drive the pressing plate frame 602 to reset as a whole, and the screw rod module 201 cooperates with the connecting plate frame 202 to drive the back-pushing and correcting plate frame 204 to move. The moving back-pushing and correcting plate frame 204 pushes the paper product to the lower part of the cutting tool body 302 and levels the side of the paper product away from the cutting tool body 302. Then, the diagonal cutting mechanism 3 and the paper pressing mechanism 6 perform repeated actions to cut the other side of the paper product.

[0087] When the overall cutting of the paper product is completed and blanking is required, the piston rod of the fourth hydraulic cylinder 703 is used to push the arc-shaped connecting frame 702 to move. The moving arc-shaped connecting frame 702 drives the guide plate 701 to fit with the processing table 102. Then, the screw rod module 201 cooperates with the connecting plate frame 202 to drive the back-pushing and correcting plate frame 204 to penetrate into the upper box frame 103 to push the paper product out of the upper box frame 103, and then perform blanking operation outside the upper box frame 103.

[0088] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various changes or substitutions, and these should all be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claimed rights.
