[0002] Paper is an essential medium for printing, and the quality and size of paper determine the environmental friendliness of printing. Currently, under the concept of green environmental protection, it is necessary to ensure green printing. Green printing refers to the use of environmentally friendly materials and processes, which generates less pollution and saves resources and energy during the printing process. Cutting paper into appropriate sizes is a step in the green printing process.

[0003] In wood powder printing shops, traditional cutting equipment makes it difficult to automatically control the cutting length of paper. Operators usually need to manually push the paper close to the blade to control the cutting length. This method of cutting paper poses a great safety hazard because it requires both hands to be close to the blade, and it is also inefficient and inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a paper cutting device that can cut at a fixed distance, in order to solve the problem that most existing technologies require operators to manually push the paper close to the blade to move it in order to control the length of the paper cut. This method of paper cutting requires both hands to be close to the blade, which poses a great safety hazard and is also inefficient and inconvenient.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a paper slitting device capable of fixed-distance cutting, comprising: a placement part: paper can be placed on the placement part, the length of the placement part can be adjusted, so that the length of the paper on the placement part can be adjusted according to the length of the placement part, and the paper can be cut along the edge of the placement part to obtain paper of different lengths; a cutting blade: the cutting blade is located above one end of the placement part, and the cutting blade can move up and down along the height direction of the placement part, so that the paper can be cut along the edge of the placement part; a driving part: disposed below the placement part, used to adjust the length of the placement part, and can adjust the position of the placement part so that the cutting blade can contact the end of the placement part when it moves up and down.

[0006] A further technical solution of this utility model is that the placement part includes a fixed plate, a first movable frame and a second movable frame are slidably connected on the fixed plate, the cutting blade is located on the side of the second movable frame away from the first movable frame, the placement plate is fixedly connected on the first movable frame, and the end of the placement plate away from the first movable frame is disposed on the second movable frame.

[0007] A further technical solution of this utility model is that the placement plate is composed of several load-bearing blocks that are hinged together.

[0008] A further technical solution of this utility model is that a number of load-bearing plates are fixedly connected to one side of the second movable frame near the first movable frame, and the end of the load-bearing plate away from the second movable frame passes through the first movable frame and extends to the other side of the first movable frame, with the upper surface of the load-bearing plate in contact with the bottom surface of the placement plate.

[0009] A further technical solution of this utility model is that the load-bearing plate and the first movable frame are connected by ratchet teeth and pawls.

[0010] A further technical solution of this utility model is that the driving unit includes a base disposed below the fixed plate, a half gear is rotatably connected inside the fixed plate, a toothed groove is opened on the bottom surface of one of the load-bearing plates, and the half gear meshes with the load-bearing plate through the toothed groove.

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0018] like Figure 1 and Figure 2 As shown, a paper slitting device capable of fixed-distance cutting includes a placement section and a cutting blade 2. Paper can be placed on the placement section, and the length of the placement section can be adjusted so that the length of the paper on the placement section can be adjusted according to the length of the placement section. Then, the paper is cut along the edge of the placement section to obtain paper of different lengths. The cutting blade 2 is located above one end of the placement section and is connected to an external drive source. The cutting blade 2 can move up and down along the height direction of the placement section, so that the paper can be cut along the edge of the placement section. A drive section is provided below the placement section to adjust the length of the placement section and adjust the position of the placement section so that the cutting blade 2 can contact the end of the placement section when it moves up and down, so that the length of the placement section can be easily adjusted to cut paper of different lengths.

[0019] like Figure 1 and Figure 2 As shown, the placement section includes a fixed plate 11, on which a first movable frame 12 and a second movable frame 13 are slidably connected. The cutting blade 2 is located on the side of the second movable frame 13 away from the first movable frame 12. A placement plate 14 is fixedly connected to the first movable frame 12. One end of the placement plate 14 away from the first movable frame 12 is disposed on the second movable frame 13. The placement plate 14 is composed of several load-bearing blocks hinged together. When the second movable frame 13 moves toward the first movable frame 12, the number of load-bearing blocks between the first movable frame 12 and the second movable frame 13 will decrease. The load-bearing blocks on the side of the second movable frame 13 away from the first movable frame 12 will fold downward under the action of gravity, thereby reducing the length of the paper above the placement section. When the cutting blade 2 is activated, it can cut the paper along the length of the second movable frame 13, thus obtaining paper of different lengths.

[0020] like Figure 2 As shown, several load-bearing plates 4 are fixedly connected to one side of the second movable frame 13 near the first movable frame 12. The end of the load-bearing plate 4 away from the second movable frame 13 passes through the first movable frame 12 and extends to the other side of the first movable frame 12. The upper surface of the load-bearing plate 4 is in contact with the bottom surface of the placement plate 14. The load-bearing plate 4 supports the placement plate 14, which can prevent the middle of the placement plate 14 from sinking under the action of gravity, keep the placement plate 14 in a horizontal state, and make it easier to move the placement plate 14 on the load-bearing plate 4, thereby making it easy to adjust the length of the placement plate 14.

[0021] It should be noted that the load-bearing plate 4 and the first moving frame 12 are connected by ratchet and pawl, so that when the load-bearing plate 4 moves toward the first moving frame 12, the load-bearing plate 4 cannot drive the first moving frame 12 to move synchronously under the action of the ratchet and pawl. Conversely, when the first moving frame 12 moves toward the second moving frame 13, the load-bearing plate 4 can move synchronously with the first moving frame 12.

[0022] like Figure 2 As shown, the drive unit includes a base 31 disposed below the fixed plate 11. A half gear 32 is rotatably connected inside the fixed plate 11. A toothed groove is formed on the bottom surface of one of the load-bearing plates 4, and the half gear 32 meshes with the load-bearing plate 4 through the toothed groove. A rack 34 is slidably connected to the base 31, and the half gear 32 meshes with the rack 34. A connecting rod 35 is fixedly connected to the rack 34, and the end of the connecting rod 35 away from the rack 34 is fixedly connected to the first moving frame 12. The half gear 32 is connected to an external drive source, causing the half gear 32 to rotate. When the half gear 32 rotates to the position where it meshes with the load-bearing plate 4, the drive unit is activated. When the load plate 4 is engaged, the rotation of the half gear 32 can drive the second moving frame 13 to move the first moving frame 12 through the load plate 4, thereby making it easy to adjust the length of the placement plate 14. When the half gear 32 rotates to engage with the rack 34, the rotation of the half gear 32 can push the first moving frame 12 toward the second moving frame 13 through the rack 34. When the first moving frame 12 moves, it can drive the second moving frame 13 to move through the load plate 4, so that the second moving frame 13 moves below the cutting blade 2, thereby making it easy to cut the paper.

[0023] Furthermore, the first movable frame 12 is equipped with a fixing clamp, which can clamp and fix the paper located at one end of the first movable frame 12, thereby preventing the paper from shifting when the cutting blade 2 cuts the paper and affecting the cutting work.

[0024] Working principle: First, the paper is placed on the placement section. Then, the drive unit is activated to adjust the length of the placement section. The length of the paper on the placement section is adjusted accordingly. Next, the drive unit can simultaneously adjust the position of the placement section, moving the end of the placement section near the cutter 2 to below the cutter 2. Finally, the cutter 2 is connected to an external drive source, allowing it to move up and down along the height of the placement section. This allows the paper to be cut along the edge of the placement section, thus easily cutting paper of different lengths. This effectively improves safety and cutting efficiency.
