Description

Technical Field

[0001] The present invention relates to the technical field of cutting of printed products, and particularly to a cutting device for printed products. Background Art

[0002] A machine for printing words and images. Modern printing presses generally consist of mechanisms such as plate loading, inking, impression, and paper feeding. Its working principle is as follows: First, the words and images to be printed are made into printing plates and installed on the printing press. Then, ink is applied to the areas with words and images on the printing plate by manual or the printing press, and then directly or indirectly transferred to paper or other printing substrates, thereby reproducing the same printed products as the printing plates. The invention and development of printing presses play an important role in the dissemination of human civilization and culture.

[0003] Most of the currently used printing equipment has a fixed paper size. Generally, multiple layers of paper need to be stacked together for a certain amount of cutting. However, when the existing device cuts multiple layers of paper, due to the inclination of the bottom and top of the cutting knife, when cutting multiple layers of paper simultaneously, the top layer of paper will slide, thus affecting the stability of paper cutting. Summary of the Invention

[0004] The purpose of the present invention is to provide a cutting device for printed products to solve the problems raised in the above background art.

[0005] To solve the above technical problems, the present invention is realized through the following technical solutions:

[0006] The present invention is a cutting device for printed products, including a workbench. A concave shell is fixedly connected to the top of the workbench. A fixed shell is fixedly connected to one side of the top of the workbench close to the concave shell. A square groove is opened at the top of the workbench far from the fixed shell. It also includes a stable cutting mechanism. The stable cutting mechanism includes an electric telescopic rod fixedly connected to the top of the concave shell. The movable end of the electric telescopic rod penetrates through the concave shell and extends to the outside of the concave shell. On both sides of the inner wall top of the concave shell, limiting rods are respectively fixedly connected. The bottom of the electric telescopic rod is fixedly connected with a fixing plate. One end outer wall of the limiting rod penetrates through the fixing plate and is slidably connected to the inner wall of the fixing plate. A slanted cutting knife is fixedly connected to the bottom of the fixing plate. A clamping assembly is arranged at the bottom of the fixing plate.

[0009] Further, a positioning component is arranged on the side wall of the moving plate. The positioning component includes rotating bars rotatably connected to both ends of the side of the moving plate away from the connecting rod. One end of the rotating bar away from the moving plate is rotatably connected with a moving block. One end of the moving block is slidably connected to one side of the inner wall of the connecting shell. The other end of the moving block is fixedly connected with a round rod.

[0010] Further, one end of the round rod penetrates through the connecting shell and extends to the outside of the connecting shell. One end of the round rod away from the moving block is fixedly connected with a clamping plate. A square plate is arranged in contact with one side of the clamping plate close to the round rod. One side of the square plate is fixedly connected with a pressing frame. One end of the pressing frame penetrates through the concave shell and extends to the inside of the concave shell. A second spring is fixedly connected to one side of the square plate close to the pressing frame. One end of the second spring is fixedly connected to the outer wall of the concave shell.

[0011] Further, an anti-jamming component is arranged on the inner wall of the fixed shell. The anti-jamming component includes a clamping plate slidably connected to the inner wall of the fixed shell. One side of the top of the clamping plate penetrates through and is slidably connected with a fixed rod. Both ends of the fixed rod are fixedly connected to the inner cavity of the fixed shell. A first return spring is fixedly connected to the side wall of the clamping plate.

[0012] Further, one end of the first return spring is fixedly connected to one side of the inner cavity of the fixed shell. A first limiting hole is opened at the top of the fixed shell.

[0014] Further, an auxiliary component is arranged on the top of the pressing frame. The auxiliary component includes a rotating plate rotatably connected to the top of the pressing frame. The top end of the rotating plate is rotatably connected with a lifting block. One end of the outer wall of the lifting block is slidably connected to one side of the inner wall of the concave shell. One end of the lifting block is fixedly connected with a lifting plate.

[0015] The present invention has the following beneficial effects:

[0016] (1) In this invention, multiple layers of paper are placed on the top of the workbench. The electric telescopic rod is started, and it drives the fixed plate to descend. The fixed plate drives the rotating rod to descend. Limited by the chute, the rotating rod drives the slider to slide along the inner wall of the chute. The slider drives the cross bar to move. The cross bar drives the connecting shell to move. The connecting shell drives the moving plate to move. The moving plate drives the connecting rod to move. The connecting rod drives the concave plate to move. During the movement of the concave plate, it will come into contact with the side of the multiple layers of paper, causing the bottom side of the multiple layers of paper to come into contact with the side wall of the fixed shell, making the multiple layers of paper stacked neatly, facilitating subsequent cutting work. Moreover, the fixed plate drives the inclined cutter to descend. During the descent of the inclined cutter, it will come into contact with the top of the multiple layers of paper, thereby performing stable cutting work on the multiple layers of paper.

[0017] (2) In this invention, due to the inclined setting on one side of the inclined cutter, when the inclined cutter performs cutting work on the multiple layers of paper, clamped by the concave plate, the cut paper moves along the inclined part of the inclined cutter. When the paper moves, it will come into contact with the positioning plate, causing the positioning plate to slide along the outer wall of the fixed rod, thereby preventing the paper from getting stuck during cutting, improving the stability of paper cutting, and facilitating the inclined cutter to cut the multiple layers of paper at the bottom. When the positioning plate moves, it drives the L-shaped plate to move. The L-shaped plate drives the cross plate to move. The cross plate drives the sliding frame to move. The sliding frame drives the roller frame to move. During the movement of the roller frame, it can roll-press the top of the multiple layers of paper to prevent the multiple layers of paper from bending during clamping. Due to the elastic deformation of the second return spring, the second return spring drives the roller frame to descend vertically, further improving the rolling-pressing effect of the roller frame on the multiple layers of paper and improving the stability of cutting the multiple layers of paper from the side.

[0018] (3) In this invention, when the concave plate clamps the multiple layers of paper, due to the reaction force of the multiple layers of paper, the multiple layers of paper cause the concave plate to drive the connecting rod to move towards the connecting shell. The connecting rod drives the moving plate to move into the interior of the connecting shell. The moving plate drives the rotating bar to move. Limited by the inner wall of the connecting shell, the rotating bar drives the moving block to move along one side of the inner wall of the connecting shell. The moving block drives the round rod to move. The two round rods move closer to each other. The round rod drives the clamping plate to move. During the movement of the clamping plate, it will come into contact with the side wall of the square plate, causing the square plate to be squeezed. The square plate drives the extrusion frame to move. The two extrusion frames move closer to each other, thereby centering the multiple layers of paper and preventing the multiple layers of paper from sliding left and right during cutting, improving the stability of cutting the multiple layers of paper.

[0019] (4) In the present invention, when the extrusion frame moves, the extrusion frame drives the rotating plate to move. Due to the inner wall of the concave shell, the rotating plate drives the lifting block to vertically descend along the inner wall of the concave shell. The lifting block drives the lifting plate to descend. At this time, the roller frame will move near the fixed shell. During the descent of the lifting plate, it will contact the top of the roller frame, causing the roller frame to further press down, improving the stability of paper cutting. Due to the rollers provided inside the roller frame, when the paper is moved by the side extrusion of the inclined cutter, the contact between the paper and the rollers can reduce the friction force, prevent the paper from being damaged by friction during movement, and improve the protection effect during paper cutting.

[0020] Of course, it is not necessary for any product implementing the present invention to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

A clamping component 55 is arranged at the bottom of the fixing plate 53.

[0036] The clamping assembly 55 includes rotating rods 551 rotatably connected to both sides of the bottom of the fixed plate 53. The bottom ends of the rotating rods 551 are rotatably connected with sliders 552. Slide grooves 553 are respectively formed on both sides of the top of the workbench 1. The outer wall of the bottom end of the slider 552 is slidably connected to the inner wall of the slide groove 553. A square hole 554 is formed on one side of the bottom end of the limiting rod 52. One side of the top end of the slider 552 is fixedly connected with a cross bar 555. One end of the outer wall of the cross bar 555 is slidably connected to the inner wall of the square hole 554.

During the movement of the concave plate 5510, it will contact the side of the multiple layers of paper, so that one side of the bottom end of the multiple layers of paper contacts the side wall of the fixed shell 3, making the multiple layers of paper stacked neatly and facilitating subsequent cutting work.

[0038] The side wall of the moving plate 558 is provided with a positioning component 56. When the concave plate 5510 clamps multiple layers of paper, due to the reaction force of the multiple layers of paper, the multiple layers of paper cause the concave plate 5510 to drive the connecting rod 559 to move towards the connecting shell 556. The connecting rod 559 drives the moving plate 558 to move into the interior of the connecting shell 556. The moving plate 558 drives the rotating bar 561 to move. Limited by the inner wall of the connecting shell 556, the rotating bar 561 drives the moving block 562 to move along one side of the inner wall of the connecting shell 556. The moving block 562 drives the round rod 563 to move. The two round rods 563 move closer to each other. The round rod 563 drives the clamping plate 564 to move. During the movement of the clamping plate 564, it will come into contact with the side wall of the square plate 565, causing the square plate 565 to be squeezed. The square plate 565 drives the extrusion frame 567 to move. The two extrusion frames 567 move closer to each other, thereby centering the multiple layers of paper and preventing the multiple layers of paper from sliding left and right during the cutting operation, improving the stability of cutting the multiple layers of paper. The positioning component 56 includes rotating bars 561 rotatably connected to both ends of the side of the moving plate 558 away from the connecting rod 559. One end of the rotating bar 561 away from the moving plate 558 is rotatably connected to a moving block 562. One end of the moving block 562 is slidably connected to one side of the inner wall of the connecting shell 556. The other end of the moving block 562 is fixedly connected to a round rod 563.

[0039] One end of the round rod 563 penetrates through the connecting shell 556 and extends to the outside of the connecting shell 556. The end of the round rod 563 away from the moving block 562 is fixedly connected to a clamping plate 564. One side of the clamping plate 564 close to the round rod 563 is in contact with a square plate 565. One side of the square plate 565 is fixedly connected to an extrusion frame 567. One end of the extrusion frame 567 penetrates through the concave shell 2 and extends to the inside of the concave shell 2. One side of the square plate 565 close to the extrusion frame 567 is fixedly connected to a second spring 566. One end of the second spring 566 is fixedly connected to the outer wall of the concave shell 2.

[0040] The inner wall of the fixed shell 3 is provided with an anti-jamming component 57. The anti-jamming component 57 includes a clamping plate 571 slidably connected to the inner wall of the fixed shell 3. One side of the top end of the clamping plate 571 penetrates and is slidably connected to a fixed rod 572. Due to the inclined setting of one side of the inclined cutter 54, when the inclined cutter 54 cuts multiple layers of paper, clamped by the concave plate 5510, the cut paper moves along the inclined part of the inclined cutter 54. When the paper moves, it will come into contact with the clamping plate 571, causing the clamping plate 571 to slide along the outer wall of the fixed rod 572, thereby preventing the paper from jamming during cutting, improving the stability of paper cutting, and facilitating the inclined cutter 54 to cut the multiple layers of paper at the bottom. Both ends of the fixed rod 572 are fixedly connected to the inner cavity of the fixed shell 3. The side wall of the clamping plate 571 is fixedly connected to a first return spring 573.

[0041] One end of the first return spring 573 is fixedly connected to one side of the inner cavity of the fixed shell 3. A first limiting hole 574 is formed in the top of the fixed shell 3, a second limiting hole 576 is formed in the top of the concave shell 2, an L-shaped plate 575 is fixedly connected to the top of the clamping plate 571, one end outer wall of the L-shaped plate 575 is slidably connected to the inner wall of the first limiting hole 574, and one end outer wall of the L-shaped plate 575 is slidably connected to the inner wall of the second limiting hole 576.

[0042] A cross plate 577 is fixedly connected to the bottom of the end of the L-shaped plate 575 away from the clamping plate 571. Sliding frames 578 penetrate through and are slidably connected to both sides of the top of the cross plate 577 respectively. A roller frame 5710 is fixedly connected to the bottom of the sliding frame 578. When the clamping plate 571 moves, the clamping plate 571 drives the L-shaped plate 575 to move, the L-shaped plate 575 drives the cross plate 577 to move, the cross plate 577 drives the sliding frame 578 to move, and the sliding frame 578 drives the roller frame 5710 to move. During the movement of the roller frame 5710, the top of multiple layers of paper can be rolled, preventing the multiple layers of paper from bending when being clamped. Due to the elastic deformation of the second return spring 579, the second return spring 579 drives the roller frame 5710 to vertically descend, further improving the rolling effect of the roller frame 5710 on multiple layers of paper, and laterally improving the stability of cutting multiple layers of paper. Second return springs 579 are fixedly connected to both sides of the top of the roller frame 5710 respectively, and the tops of the second return springs 579 are fixedly connected to the bottom of the cross plate 577.

[0043] In Embodiment 2, an auxiliary component 58 is arranged on the top of the extrusion frame 567. When the extrusion frame 567 moves, the extrusion frame 567 drives the rotating plate 581 to move. Due to the inner wall arrangement of the concave shell 2, the rotating plate 581 drives the lifting block 582 to vertically descend along the inner wall of the concave shell 2, and the lifting block 582 drives the lifting plate 583 to descend. At this time, the roller frame 5710 will move to the vicinity of the fixed shell 3. During the descent of the lifting plate 583, it will come into contact with the top of the roller frame 5710, enabling the roller frame 5710 to further perform the pressing work, improving the stability of paper cutting. Due to the rollers arranged inside the roller frame 5710, when the paper moves under the side extrusion of the inclined cutter 54, the contact between the paper and the rollers can reduce the friction force, preventing the paper from being damaged by friction when moving, and improving the protection effect during paper cutting. The auxiliary component 58 includes a rotating plate 581 rotatably connected to the top of the extrusion frame 567, a lifting block 582 rotatably connected to the top end of the rotating plate 581, one end outer wall of the lifting block 582 is slidably connected to one side of the inner wall of the concave shell 2, and a lifting plate 583 is fixedly connected to one end of the lifting block 582.

[0044] During use, place multiple layers of paper on the top of the workbench 1, start the electric telescopic rod 51, the electric telescopic rod 51 drives the fixed plate 53 to descend, the fixed plate 53 drives the rotating rod 551 to descend, restricted by the chute 553, the rotating rod 551 drives the slider 552 to slide along the inner wall of the chute 553, the slider 552 drives the cross bar 555 to move, the cross bar 555 drives the connecting shell 556 to move, the connecting shell 556 drives the moving plate 558 to move, the moving plate 558 drives the connecting rod 559 to move, the connecting rod 559 drives the concave plate 5510 to move, and during the movement of the concave plate 5510, it will come into contact with the side of the multiple layers of paper, making the bottom side of the multiple layers of paper come into contact with the side wall of the fixed shell 3, stacking the multiple layers of paper neatly, facilitating subsequent cutting work, and the fixed plate 53 drives the inclined cutter 54 to descend, and during the descent of the inclined cutter 54, it will come into contact with the top of the multiple layers of paper, thereby performing stable cutting work on the multiple layers of paper.

[0045] Due to the inclined setting on one side of the inclined cutter 54, when the inclined cutter 54 performs cutting work on the multiple layers of paper, clamped by the concave plate 5510, the cut paper moves along the inclined part of the inclined cutter 54, and when the paper moves, it will come into contact with the positioning plate 571, causing the positioning plate 571 to slide along the outer wall of the fixed rod 572, thereby preventing paper jamming during cutting, improving the stability of paper cutting, facilitating the inclined cutter 54 to cut the multiple layers of paper at the bottom. When the positioning plate 571 moves, the positioning plate 571 drives the L-shaped plate 575 to move, the L-shaped plate 575 drives the cross plate 577 to move, the cross plate 577 drives the sliding frame 578 to move, the sliding frame 578 drives the roller frame 5710 to move, and during the movement of the roller frame 5710, it can roll-press the top of the multiple layers of paper to prevent the multiple layers of paper from bending during clamping. Due to the elastic deformation of the second return spring 579, the second return spring 579 drives the roller frame 5710 to descend vertically, further improving the roll-pressing effect of the roller frame 5710 on the multiple layers of paper and laterally improving the stability of cutting the multiple layers of paper.

[0046] When the concave plate 5510 clamps multiple layers of paper, under the reaction force of the multiple layers of paper, the multiple layers of paper cause the concave plate 5510 to drive the connecting rod 559 to move towards the connection shell 556. The connecting rod 559 drives the moving plate 558 to move into the interior of the connection shell 556. The moving plate 558 drives the rotating bar 561 to move. Restricted by the inner wall of the connection shell 556, the rotating bar 561 drives the moving block 562 to move along one side of the inner wall of the connection shell 556. The moving block 562 drives the round rod 563 to move. The two round rods 563 move closer to each other. The round rod 563 drives the clamping plate 564 to move. During the movement of the clamping plate 564, it will come into contact with the side wall of the square plate 565, causing the square plate 565 to be squeezed. The square plate 565 drives the extrusion frame 567 to move. The two extrusion frames 567 move closer to each other, thereby centering the multiple layers of paper and preventing the multiple layers of paper from sliding left and right during the cutting operation, improving the stability of cutting the multiple layers of paper.

[0047] When the extrusion frame 567 moves, the extrusion frame 567 drives the rotating plate 581 to move. Restricted by the inner wall of the concave shell 2, the rotating plate 581 drives the lifting block 582 to vertically descend along the inner wall of the concave shell 2. The lifting block 582 drives the lifting plate 583 to move downward. At this time, the roller frame 5710 will move to the vicinity of the fixed shell 3. During the descent of the lifting plate 583, it will come into contact with the top of the roller frame 5710, causing the roller frame 5710 to further press down, improving the stability of paper cutting. Due to the setting of the rollers inside the roller frame 5710, when the paper is squeezed and moved by the side of the inclined cutter 54, the contact between the paper and the rollers can reduce the friction force, prevent the paper from being damaged by friction during movement, and improve the protection effect during paper cutting.
