Description

Technical Field

[0001] The utility model relates to the technical field of printed matter cutting, in particular to a cutting device for printed matter. Background Art

[0002] Printed matter is the general term for various finished products produced by printing technology. It has a wide variety of types and almost covers all aspects of people's daily life. Some common types of printed matter include books, magazines and newspapers, leaflets and posters, and packaging boxes and labels, etc. The design of printed matter usually includes specific sizes and shapes, which need to be achieved through cutting.

[0003] For example, the Chinese utility model patent with the publication number of "CN220241645U" discloses "a cutting device for printed matter production, comprising a base. A cutting groove is formed between the central positions of two longer sides at the top of the base. A fixed block is installed at one shorter edge of the top of the base. One end of the outer side of the fixed block is installed with a servo motor. One end of the top of the base close to the fixed block is installed with a first movable block. Through the designed cutting device for printed matter production, the servo motor drives the bidirectional threaded rod to rotate, driving the first movable block and the second movable block to move relatively to clamp and fix the two ends of the stacked paper printed matter. The second electric telescopic rod contracts to drive the two pressing plates to descend to press and fix the top of the stacked paper printed matter again, thus solving the problem that the traditional cutting device for printed matter production is prone to deviation during cutting and affecting the cutting accuracy due to the lack of a fixing structure during cutting."

[0004] In view of the above related technologies, although the printed matter can be fixed during cutting, since the first movable block and the second movable block move towards each other, this means that after each fixing of the printed matter, the cutting knife can only cut at the middle position of the printed matter. Although this design simplifies the fixing process, it greatly limits the cutting flexibility. In practical applications, it is inconvenient to perform fixed-length cutting on the printed matter according to different printed matter sizes and cutting requirements, resulting in a significant reduction in the practicality of the device. Therefore, those skilled in the art provide a cutting device for printed matter to solve the problems raised in the above background art.

Specific Embodiments

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] An embodiment of the present utility model discloses a cutting device for printed matter. Refer to Figures 1-3, A cutting device for printed matter, comprising a processing table 1, a cutting mechanism, a fixing mechanism and a positioning assembly. A support plate 2 is arranged at the upper end of the processing table 1, an electric push rod 3 is arranged at the top of the support plate 2, and a cutting mechanism is arranged at the bottom end of the electric push rod 3 for cutting the printed matter. Two groups of symmetrically distributed fixing mechanisms are arranged on the cutting mechanism for fixing the printed matter during cutting. A positioning assembly is arranged on the processing table 1 for performing length-fixed cutting on the printed matter;

[0028] Referring to Figure 1 , The cutting mechanism includes a connecting plate 4 and a cutting knife 5. The connecting plate 4 is arranged at the bottom end of the electric push rod 3, and a cutting knife 5 is arranged at its bottom end for cutting the printed matter.

[0029] By adopting the above technical solution, when cutting the printed matter, the electric push rod 3 works to drive the connecting plate 4 to move downward, and the downward movement of the connecting plate 4 drives the cutting knife 5, so that the printed matter can be cut by the cutting knife 5.

[0030] Referring to Figure 1 , The fixing mechanism includes a sleeve 6, a spring 7, a T-shaped rod 8 and a pressing plate 9. The sleeve 6 is arranged at the upper end of the connecting plate 4, and a T-shaped groove is opened inside the sleeve 6. The opening at the end of the T-shaped groove extends to the end of the sleeve 6, and a spring 7 is arranged inside the T-shaped groove. The T-shaped rod 8 is slidably arranged in the T-shaped groove, and the upper end of the T-shaped rod 8 is connected to the bottom end of the spring 7. The bottom end of the T-shaped rod 8 penetrates out of the T-shaped groove and is provided with a pressing plate 9. The vertical height of the pressing plate 9 is lower than the vertical height of the cutting knife 5.

[0031] By adopting the above technical solution, when the connecting plate 4 moves downward, it will also drive the pressing plate 9 to move downward. Since the height of the pressing plate 9 is lower than the height of the cutting knife 5, when the connecting plate 4 moves downward, the pressing plate 9 contacts the printed matter first, so that the printed matter can be fixed, and the printed matter can be prevented from shifting during cutting.

[0032] Referring to Figure 1 , The positioning assembly includes a motor 10, a gear 11, a positioning plate 12 and a toothed plate 13. The motor 10 is arranged at the bottom end of the processing table 1, and a gear 11 is arranged on its output shaft. The positioning plate 12 is arranged at the upper rear side of the processing table 1, and a toothed plate 13 meshing with the gear 11 is arranged on one side thereof; A cutting groove 16 is opened at the upper end of the processing table 1 and is directly below the cutting knife 5. Two symmetrically distributed scale lines 17 are arranged at the upper end of the processing table 1, and the starting position of the scale line 17 is aligned with the center of the cutting groove 16.

[0033] By adopting the above technical solution, when it is necessary to perform fixed-length cutting on a printed matter, the motor 10 operates to drive the gear 11 to rotate. The rotation of the gear 11 drives the rack 13 to move. The movement of the rack 13 pushes the positioning plate 12 to move. When the positioning plate 12 moves, the positioning plate 12 can be moved to a suitable position for use by observing the scale line 17, which facilitates the fixed-length cutting of the printed matter.

[0034] Referring to Figure 1 , two symmetrically distributed sliders 14 are provided at the bottom end of the positioning plate 12, and two symmetrically distributed sliding grooves 15 are opened at the upper end of the processing table 1. The bottom end of the slider 14 penetrates into the sliding groove 15 and is slidably connected to the sliding groove 15.

[0035] By adopting the above technical solution, when the positioning plate 12 moves, it will drive the slider 14 to slide in the sliding groove 15, making the movement of the positioning plate 12 more stable.

[0036] Working principle: When this utility model is in use, the electrical components appearing in this application are externally connected to a power source and a control switch during use. First, place the printed matter to be cut on the upper end of the processing table 1, and make one end of the printed matter fit against the side surface of the positioning plate 12. Then, the electric push rod 3 operates to drive the connecting plate 4 to move downward. The downward movement of the connecting plate 4 drives the cutting knife 5 and the pressing plate 9 to move downward. Since the height of the pressing plate 9 is lower than the height of the cutting knife 5, when the connecting plate 4 moves downward, the pressing plate 9 first contacts the printed matter to fix it. Then, as the connecting plate 4 continues to move downward, the cutting knife 5 contacts the printed matter, enabling the cutting of the printed matter. When it is necessary to perform fixed-length cutting on the printed matter, the motor 10 operates to drive the gear 11 to rotate. The rotation of the gear 11 drives the rack 13 to move. The movement of the rack 13 pushes the positioning plate 12 to move. When the positioning plate 12 moves, the positioning plate 12 can be moved to a suitable position for use by observing the scale line 17. Then, after cutting with the end of the printed matter fitting against the positioning plate 12, the scale at the position where the positioning plate 12 is located is the cutting length of the printed matter, which facilitates the fixed-length cutting of the printed matter, thus greatly improving the practicability of the device.

[0037] When this utility model is in use, it can automatically fix the printed matter during cutting and can precisely adjust the cutting length of the printed matter, which facilitates the fixed-length cutting of the printed matter, thus greatly improving the practicability of the device.
