Description

Technical Field

[0001] This utility model belongs to the field of printing and processing technology, and in particular relates to a rapid positioning device for a paper cutter used in printing and processing. Background Technology

[0002] A paper cutter for printing processing is a mechanical device specifically used for cutting printed materials. It uses blades or blade sets to precisely cut printed materials such as paper, cardboard, and plastic sheets to meet the size, shape, and process requirements of the printed materials.

[0003] Traditional paper cutters typically have a moving plate on the worktable for positioning the paper. While this method can achieve the desired positioning, it only keeps the front and back areas of the paper flat after positioning. The left and right sides of the paper will still be uneven, requiring the operator to manually straighten them. This not only increases the number of steps but also poses a safety hazard, as the operator's hands are easily cut by the blade during the straightening process. Utility Model Content

[0004] The purpose of this invention is to provide a rapid positioning device for a paper cutter used in printing and processing. By setting a positioning mechanism, specifically, the paper is pushed into the paper cutter so that the back of the paper contacts the positioning plate, thereby quickly positioning the front and back of the paper. Then, the electric push rod is activated to move the U-shaped frame forward, so that the two side positioning plates move closer to each other, pushing and tidying the left and right sides of the paper. This not only makes the stacked paper more neat, but also enables rapid positioning in the left and right directions, eliminating the need for manual tidying by the operator and effectively protecting the operator from injury. This solves the problem that traditional paper cutters usually have a moving plate on the worktable for positioning the paper, which can only keep the front and back areas of the paper flat, while the left and right sides of the paper are still uneven, requiring the operator to manually tidy the sides of the paper.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a quick positioning device for a paper cutter used in printing and processing, comprising a base, a worktable fixedly connected to the top of the base, a paper cutter mounted on the top of the worktable, two limiting plates fixedly connected to the back of the paper cutter, and further comprising:

[0007] A positioning mechanism is provided on the back of the paper cutter. The positioning mechanism includes a positioning plate slidably connected to the top of the worktable; two side positioning plates are provided in front of the positioning plate; a U-shaped frame is provided behind the positioning plate; an electric push rod is fixedly connected to the top of the positioning plate; the output end of the electric push rod is fixedly connected to the inner side of the U-shaped frame; and inclined plates are fixedly connected to the back of both side positioning plates.

[0008] A rotating mechanism is located in front of the paper cutter and is used to quickly rotate and reposition stacked papers.

[0009] The inclined plate is set with an inclined surface on the side facing the U-shaped frame, and the inclined surface on the inclined plate is in contact with the front end of the U-shaped frame.

[0010] Furthermore, a connecting protrusion is fixedly connected to the center of the back of the positioning plate, and a limit rod is fixedly connected to the left and right sides of the connecting protrusion. A spring is sleeved on the outside of the limit rod, and two limit grooves are opened on the top of the positioning plate. When the inclined plate is pushed, the spring is squeezed by the connecting plate, so that the inclined plate can be smoothly returned to its original position by the elastic force.

[0011] The inclined plate is fixedly connected to a connecting plate at its bottom, and the limiting rod slides through the limiting rod and extends to the outside. The limiting rod is used to limit the inclined plate.

[0012] Furthermore, one end of the spring is fixedly connected to the surface of the connecting protrusion, and the other end of the spring is fixedly connected to the connecting plate at the bottom of the inclined plate. A limit slider is fixedly connected to the top of the inner side of the side positioning plate. The limit slider is slidably connected inside the limit groove. The bottom of the side positioning plate is in contact with the top of the worktable. The limit slider slides in the groove, which makes the side positioning plate move more smoothly and allows it to make linear motion.

[0013] Furthermore, the rotating mechanism includes a rotating groove on the top of the worktable, a circular limiting groove at the bottom of the rotating groove, a turntable rotatably connected inside the rotating groove, a plurality of slots at the top of the turntable, and a limiting shaft fixedly connected at the center of the bottom of the turntable; the turntable rotates within the circular limiting groove via the limiting shaft at the bottom of the turntable, and the turntable rotates within the rotating groove, thus enabling the rapid rotation and repositioning of stacked papers when pushing them;

[0014] The limiting shaft is rotatably connected inside the circular limiting groove, and the limiting shaft and the circular limiting groove cooperate to limit the position of the turntable.

[0015] Furthermore, a movable block is provided at the rear of the base, and a threaded rod is threadedly connected inside the movable block. A fixed block is provided on the back of the threaded rod. The top of the fixed block is fixedly connected to the bottom of the worktable, and a motor is fixedly connected to the back of the fixed block. The front of the threaded rod is rotatably connected to the inner wall of the base. The top of the movable block slides through the worktable and extends to the bottom of the positioning plate for fixed connection. The back of the threaded rod is fixedly connected to the output end of the motor through a coupling. When the motor is started, it drives the threaded rod to rotate clockwise, causing the movable block to move forward on the threaded rod. At this time, the movable block will drive the positioning plate to move together, and the positioning plate will push the paper to move, thereby adjusting the size to be cut.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model, by setting a positioning mechanism, specifically pushes the paper into the paper cutter so that the back of the paper contacts the positioning plate, thereby quickly positioning the front and back positions of the paper. Then, the electric push rod is activated to drive the U-shaped frame forward, so that the two side positioning plates come closer to each other, which pushes and arranges the left and right sides of the paper. This not only makes the stacked paper more neat, but also enables quick positioning in the left and right directions, eliminating the need for manual arrangement by the staff and effectively protecting the staff from injury.

[0018] 2. This utility model features a rotating mechanism. Specifically, the paper to be cut is placed on a turntable. By pushing the stacked paper, the paper can be quickly rotated and repositioned. At the same time, the turntable has several slots to increase the friction of the placed paper, making the paper more stable after placement and easier to rotate and reposition.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

It also includes:

[0032] Positioning mechanism 2 is located on the back of paper cutter 12. Positioning mechanism 2 includes a positioning plate 22 slidably connected to the top of workbench 11. Two side positioning plates 23 are positioned in front of the positioning plate 22, and a U-shaped frame 24 is positioned behind the positioning plate 22. An electric push rod 241 is fixedly connected to the top of the positioning plate 22, and the output end of the electric push rod 241 is fixedly connected to the inner side of the U-shaped frame 24. Inclined plates 231 are fixedly connected to the back of each of the two side positioning plates 23. Paper is pushed into the paper cutter 12, causing the back of the paper to contact the positioning plate 22, thus quickly positioning the paper's front and back positions. Then, the electric push rod 241 is activated, moving the U-shaped frame 24 forward, causing the two side positioning plates 23 to move closer together, pushing and tidying the left and right sides of the paper. This not only makes the stacked paper more neat but also allows for rapid positioning in the left and right directions, eliminating the need for manual handling and effectively protecting workers from injury.

[0033] Rotating mechanism 3 is located in front of paper cutter 12 and is used to quickly rotate and reposition stacked papers; the inclined plate 231 is set with an inclined surface on the side facing U-shaped frame 24, and the inclined surface on the inclined plate 231 contacts the front end of U-shaped frame 24.

[0034] A connecting protrusion 221 is fixedly connected to the center of the back of the positioning plate 22. Limiting rods 222 are fixedly connected to the left and right sides of the connecting protrusion 221. A spring 223 is sleeved on the outside of the limiting rod 222. Two limiting grooves 224 are opened on the top of the positioning plate 22. A connecting plate is fixedly connected to the bottom of the inclined plate 231. The limiting rod 222 slides through the limiting rod 222 and extends to the outside. The limiting rod 222 is used to limit the inclined plate 231.

[0035] One end of the spring 223 is fixedly connected to the surface of the connecting protrusion 221, and the other end of the spring 223 is fixedly connected to the connecting plate at the bottom of the inclined plate 231.

[0036] A limiting slider 232 is fixedly connected to the top inner side of the side positioning plate 23. The limiting slider 232 is slidably connected inside the limiting groove 224. The bottom of the side positioning plate 23 is in contact with the top of the worktable 11.

[0037] The rotating mechanism 3 includes a rotating groove 33 on the top of the worktable 11, a circular limiting groove 34 at the bottom of the rotating groove 33, a turntable 31 rotatably connected inside the rotating groove 33, a number of slots 32 on the top of the turntable 31, and a limiting shaft 35 fixedly connected at the center of the bottom of the turntable 31. The paper to be cut is placed on the turntable 31, and the paper can be quickly rotated and repositioned by pushing the stacked paper. At the same time, the number of slots 32 on the turntable 31 is used to increase the friction of the placed paper, making the paper more stable after placement and easier to rotate and reposition. The limiting shaft 35 is rotatably connected inside the circular limiting groove 34, and the limiting shaft 35 cooperates with the circular limiting groove 34 to limit the position of the turntable 31.

[0038] A movable block 21 is provided at the rear of the base 1. A threaded rod 211 is threadedly connected inside the movable block 21. A fixed block 212 is provided on the back of the threaded rod 211. The top of the fixed block 212 is fixedly connected to the bottom of the worktable 11. A motor 213 is fixedly connected to the back of the fixed block 212. The front of the threaded rod 211 is rotatably connected to the inner wall of the base 1. The top of the movable block 21 slides through the worktable 11 and extends to the bottom of the positioning plate 22 for fixed connection. The back of the threaded rod 211 is fixedly connected to the output end of the motor 213 through a coupling.

[0039] One specific application of this embodiment is:

[0040] In use, the paper to be cut is placed on the workbench 11 and then on the turntable 31. Since the bottom of the turntable 31 rotates within the circular limit groove 34 via the limit shaft 35, and the turntable 31 also rotates within the rotation groove 33, the stacked paper can be quickly rotated and repositioned when the paper is pushed. Simultaneously, the turntable 31 has several slots 32 to increase friction on the placed paper, making it more stable and easier to rotate and reposition. After the paper is repositioned, it is pushed into the paper cutter 12 so that the back of the paper contacts the positioning plate 22, thus quickly positioning the paper's front and rear positions. Then, the electric push rod 241 is activated to move the U-shaped frame 24 forward. The U-shaped frame 24 will simultaneously push the two inclined plates 231. Since the back of the inclined plates 231 is sloped, the two inclined plates... Plate 231 will drive the two side positioning plates 23 to move closer to each other. At the same time, the connecting plate at the bottom of the inclined plate 231 will slide on the limiting rod 222, and the spring 223 will be squeezed. Meanwhile, the limiting slider 232 on the side positioning plate 23 will slide in the limiting groove 224. By the two side positioning plates 23 moving closer to each other, the left and right sides of the paper will be pushed and arranged. This not only makes the stacked paper more neat, but also enables quick positioning in the left and right directions. After positioning is completed, the motor 213 is started to drive the threaded rod 211 to rotate clockwise, so that the moving block 21 moves forward on the threaded rod 211. At this time, the moving block 21 will drive the positioning plate 22 to move together. The positioning plate 22 will push the paper to move, thereby adjusting the size to be cut. After the movement is completed, the motor 213 is stopped, and the stacked paper can be cut by the paper cutter 12.
