Description

Technical Field

[0001] This utility model relates to the field of corrugated paper technology, specifically to a corrugated paper slitting machine. Background Technology

[0002] Corrugated paper is a sheet-like material made by bonding linerboard and corrugated paper formed by corrugating rollers. It is generally divided into single-wall corrugated paperboard and double-wall corrugated paperboard. It has the advantages of low cost, light weight, easy processing, high strength, excellent printability, and convenient storage and handling. Corrugated paper can be recycled and can be used as packaging for food or digital products. It is relatively environmentally friendly and widely used.

[0003] Corrugated paper slitting is mainly accomplished by the blade assembly of a slitting machine. The core process involves using the interlocking action of the upper and lower blades to cut the cardboard. When the clamping force of the corrugated paper is insufficient, the cardboard is not properly secured, and the blades cannot cleanly cut the fibers. Instead, they "tear" the paper layers, which is especially damaging to the corrugated core paper, causing the fibers to "break" and resulting in rough edges. Rough edges reduce the aesthetics of the cardboard, and these rough edges are more susceptible to moisture or wear during transportation. Therefore, it is necessary to provide a method that can simultaneously clamp both sides of the corrugated paper during slitting to improve the quality of the slitting. Utility Model Content

[0004] The purpose of this utility model is to provide a corrugated paper slitting machine to solve the problems mentioned in the background section. To solve the above technical problems, this utility model is achieved through the following technical solution: This utility model is a corrugated paper slitting machine, comprising: The slitting machine comprises a fixed frame and a movable frame, wherein the fixed frame is fixed to the upper surface of the slitting machine, and the movable frame slides through the interior of the fixed frame; The clamping assembly includes a fixed frame, a first movable hole, a second movable hole, and a movable column. The fixed frames are in pairs and are fixed on both sides of the movable frame. The first movable hole is opened on the top of the fixed frame, and the second movable hole is opened on the bottom of the fixed frame. The first movable hole and the second movable hole are directly opposite each other. The movable column slides through the first movable hole and the second movable hole.

[0005] Furthermore, a circular knife is rotatably mounted inside the movable frame, and the circular knife contacts the corrugated paper.

[0006] Furthermore, a baffle is fixed to the middle of the outer surface of the movable column, and the baffle is located inside the fixed frame. A spring is fixed to one side of the baffle, and the spring is located inside the fixed frame.

[0007] Furthermore, a connecting column is fixed to the lower surface of the movable column, and a first rotating hole is formed on the lower surface of the connecting column.

[0008] Furthermore, a rotating bead is rotatably installed inside the first rotating hole. The rotating bead is located on both sides of the circular knife and is in contact with the corrugated paper.

[0009] Furthermore, it also includes an anti-deviation component, which includes a limiting post, a movable plate, and a rotating post. The limiting post is fixed to the rear side of the fixed frame. There are five movable plates that slide through the outer surface of the limiting post at equal distances. The rotating posts are in groups of two, for a total of five groups, and are fixed to both sides of the lower section of the movable plate respectively.

[0010] Furthermore, a rotating wheel is rotatably passed through the outer surface of the rotating column, and a second rotating hole is opened in the middle of one side of the outer surface of the rotating wheel, and the second rotating hole passes through the rotating column.

[0011] This utility model has the following beneficial effects: This utility model relates to a slitting machine, a fixed frame, a movable frame, a circular blade, and a pressing assembly. When slitting corrugated paper, the corrugated paper is placed on the slitting machine, and then moved until it contacts the circular blade, cutting the paper. During cutting, the movable column moves within the first and second movable holes under the elastic force of a spring. Depending on the thickness of the corrugated paper, the movable column moves upwards, bringing the rotating bead into contact with the paper and tightly pressing it against both sides of the cut. The spring force drives the movable column to move flexibly within the first and second movable holes, automatically adjusting its height according to the paper thickness, ensuring the rotating bead always fits tightly against the paper surface. This adaptive adjustment capability ensures that both sides of the cut are tightly pressed, regardless of whether the corrugated paper is thin or thick, preventing loosening or shifting due to changes in paper thickness. This significantly reduces the probability of cutting defects such as burrs and tears, improving cutting quality. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0017] Please see Figure 1-4 As shown, this utility model is a corrugated paper slitting machine, comprising: The slitting machine 11, the fixed frame 12 and the movable frame 13 are fixed on the upper surface of the slitting machine 11. The movable frame 13 slides through the inside of the fixed frame 12. A circular knife 14 is rotatably installed inside the movable frame 13 and contacts the corrugated paper. The slitting machine 11 serves as the basic carrier of the entire equipment. The fixed frame 12 acts as the supporting structure for the movable frame 13, which in turn serves as the mounting carrier for the circular blade 14.

[0018] The clamping assembly includes a fixed frame 21, a first movable hole 22, a second movable hole 23, and a movable column 24. The fixed frames 21 are in pairs and are fixed on both sides of the movable frame 13. The first movable hole 22 is opened above the fixed frame 21, and the second movable hole 23 is opened below the fixed frame 21, with the first movable hole 22 and the second movable hole 23 facing each other. The movable column 24 slides through the first movable hole 22 and the second movable hole 23. The fixed frame 21 is the basic mounting frame of the clamping assembly, providing space for the movable column 24, spring 26 and other components to be accommodated and limited. The first movable hole 22 and the second movable hole 23 restrict the movable column 24 to move only in the vertical direction, avoiding lateral displacement that affects the clamping accuracy. The up and down movement of the movable column 24 can drive the rotating bead 29 to move closer to or away from the corrugated paper, realizing dynamic adjustment of the clamping force.

[0019] A baffle 25 is fixed in the middle of the outer surface of the movable column 24, and the baffle 25 is located inside the fixed frame 21. A spring 26 is fixed on one side of the baffle 25, and the spring 26 is located inside the fixed frame 21. A connecting column 27 is fixed on the lower surface of the movable column 24. A first rotating hole 28 is opened on the lower surface of the connecting column 27. A rotating bead 29 is rotatably installed inside the first rotating hole 28. The rotating bead 29 is located on both sides of the circular knife 14, and the rotating bead 29 is in contact with the corrugated paper. The baffle 25 drives the movable column 24 to move synchronously by pushing the baffle 25. The spring 26 can adaptively adjust the elasticity by compression or extension to avoid excessive pressure damaging the paper or insufficient pressure causing loosening. The connecting column 27 serves as a connecting bridge between the movable column 24 and the rotating bead 29, extending the force arm of the movable column 24 so that the pressing point of the rotating bead 29 is closer to the cutting position of the circular knife 14. The rotating bead 29 presses the corrugated paper with the pressure transmitted by the spring 26 to prevent the paper from shifting or wrinkling during cutting. It rolls synchronously with the conveying of the corrugated paper, converting sliding friction into rolling friction and reducing wear on the surface of the corrugated paper.

[0020] Working principle: When longitudinally cutting corrugated paper, the corrugated paper is placed on the longitudinal cutter, and then the corrugated paper is moved so that it contacts the circular blade 14 and is cut. During the cutting of the corrugated paper, the movable column 24 moves within the first movable hole 22 and the second movable hole 23 under the elastic force of the spring 26. The movable column 24 can also move upward according to the thickness of the corrugated paper, so that the rotating bead 29 contacts the corrugated paper and presses the corrugated paper tightly on both sides of the cut. The movable column 24 is driven by the elastic force of the spring 26 to move flexibly within the first movable hole 22 and the second movable hole 23. The height can be automatically adjusted according to the thickness of the corrugated paper, so that the rotating bead 29 is always closely attached to the surface of the corrugated paper. This adaptive adjustment capability can ensure that the cut sides are tightly pressed regardless of whether the corrugated paper is thin or thick. This step avoids loosening or shifting caused by changes in paper thickness, greatly reducing the probability of cutting defects such as rough edges and tears, and improving cutting quality.

[0021] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes: The anti-deviation assembly includes a limiting post 31, a movable plate 32, and a rotating post 33. The limiting post 31 is fixed to the rear side of the fixed frame 12. There are five movable plates 32, which slide through the outer surface of the limiting post 31 at equal distances. The rotating posts 33 are in groups of two, for a total of five groups, which are fixed to the lower two sides of the movable plate 32 respectively. A rotating wheel 34 is rotatably passed through the outer surface of the rotating post 33. A second rotating hole 35 is opened in the middle of one side of the outer surface of the rotating wheel 34, and the second rotating hole 35 passes through the rotating post 33. The limiting post 31 restricts the movement direction of the movable plate 32, ensuring that the movable plate 32 can only be adjusted horizontally along the limiting post 31, avoiding deviation caused by vibration or external force, and providing a basis for the guiding accuracy of the subsequent rotating wheel 34. By adjusting the position of the movable plate 32 individually, the rotating wheel 34 can be precisely aligned with corrugated paper of different widths, achieving targeted guidance of "one plate to one material". The two rotating wheels 34 in each group are located on both sides of the corrugated paper and rotate synchronously with the corrugated paper conveying, reducing wear on the edges of the corrugated paper.

[0022] Working principle: After the corrugated paper is cut, the cut corrugated paper comes into contact with the rotating wheel 34, and the rotating wheel 34 rotates and presses the corrugated paper to move backward. The pressing action of the rotating wheel 34 can effectively prevent the corrugated paper from shifting, warping or stacking after cutting. The edges of the cut corrugated paper may have certain stress and are prone to shape changes. However, the continuous pressure of the rotating wheel 34 can keep the corrugated paper flat and ensure its accurate position during the conveying process, providing a stable foundation for subsequent processing steps. Secondly, the rotating wheel 34 conveys while pressing, combining the pressing and moving actions into one, simplifying the equipment structure and improving the overall work efficiency. Furthermore, the rotational characteristics of the rotating wheel 34 make the friction between it and the corrugated paper rolling friction, which can greatly reduce the damage to the surface of the corrugated paper compared with sliding friction, avoiding scratches, damage or destruction of the corrugation shape, and ensuring the appearance quality and structural strength of the corrugated paper. This step prevents scratches, damage, or disruption of the flute shape in the corrugated paper, ensuring its appearance quality and structural strength.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
