Description

Technical Field

[0001] The utility model belongs to the technical field of cardboard cutting, and relates to a cutting machine, in particular to a paper cutter for carton production. Background Art

[0002] As the most widely used packaging product, the carton undertakes the important responsibilities of containing, protecting products and being aesthetic. It is usually used as a wrapper for commodities or an outer protective object for items to protect the contents from damage and is an indispensable part of modern logistics. The carton is composed of multiple cardboard sheets, and the cardboard sheets need to be cut according to production requirements during the production process to finally obtain suitable cardboard sheets before being processed into cartons.

[0003] Currently, in the conventional cardboard cutting operation, the cardboard is first placed on the paper cutter and then pushed forward for cutting by a cutting knife. However, during the process of pushing the cardboard, since there is no fixing device on the cutting machine, the cardboard is prone to skew due to uneven force during pushing, resulting in the cardboard being unable to be precisely cut, thus causing the cutting angle to change and the cutting position of the cardboard to be incorrect, leading to waste of cardboard. Moreover, most of the cutting knives of conventional paper cutters have a fixed structure and cannot move, and the cardboard needs to be adjusted according to the cutting position, resulting in a time-consuming and cumbersome cutting process. The above-mentioned problems reduce the efficiency of carton production and increase losses. Summary of the Utility Model

[0004] The utility model provides a paper cutter for carton production in view of the deficiencies of the prior art. By using the cooperation of a limiting plate and a fixing mechanism to fix the cardboard, it can prevent the cardboard from shifting during pushing. Then, according to the position where the cardboard needs to be cut, the position of the cutting knife is adjusted by a positioning motor, and then cutting can be carried out. This not only avoids the problem of incorrect cutting position of the cardboard, but also eliminates the need to adjust and place the cardboard, reduces losses and improves the production efficiency of cartons, and has the characteristics of high stability and convenient cutting.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A paper cutter for carton production, comprising a frame, with feet provided at the bottom of the frame, a limit plate, a transverse chute, a fixing mechanism and a vertical chute provided at the front of the frame. The limit plate is arranged parallel to the vertical chute and perpendicular to the transverse chute respectively. An adjusting slider is provided at the bottom of the limit plate, and the limit plate is connected to the transverse chute through the adjusting slider, so that the limit plate can move along the transverse chute. A limit chute is provided at the top of the limit plate. One end of the fixing mechanism is movably arranged in the limit chute, and the other end is movably arranged in the vertical chute. When the cardboard is pushed forward, one side of the cardboard is aligned by the limit plate, and then the other side of the cardboard is fixed by the fixing mechanism. As the cardboard is pushed forward, the fixing mechanism can move on the frame through the limit chute and the vertical chute; An adjusting port is provided at the rear of the frame, an adjusting screw is provided in the adjusting port, an adjusting motor is provided on the frame on the side of the adjusting port, the output end of the adjusting motor is connected to the adjusting screw, and the adjusting screw is located in the adjusting port. An adjusting seat is provided on the adjusting screw, a cutting motor and a cutting knife are provided on the adjusting seat, the output end of the adjusting motor is connected to the cutting knife through a transmission shaft, and the cutting knife is located at the adjusting port. When the adjusting motor rotates, it drives the adjusting screw to rotate, so that the adjusting seat moves on the adjusting screw, thereby adjusting the position of the cutting knife at the adjusting port; A collection box is provided at the end of the frame. The cut cardboard can continue to be pushed to the end of the frame and fall into the collection box, which is convenient for workers to sort out;

[0007] The fixing mechanism is composed of a connecting frame, a limit post, a downward pressing screw, a downward pressing fixing plate and a sliding plate. An adjusting groove is provided at the left part of the connecting frame. One end of the limit post is movably arranged in the limit chute, and the other end is movably connected to the adjusting groove through a limit bolt. When the limit plate moves in the transverse chute according to the size of the cardboard, it can drive the limit post to move in the limit groove. After the limit plate moves to the corresponding position, tighten the limit bolt to fix the limit post in the adjusting groove, so as to achieve the purpose of fixing the limit plate in the transverse chute; The sliding plate is located in the vertical chute and is connected to the bottom end of the right part of the connecting frame. A downward pressing screw is provided on the connecting frame corresponding to the upper part of the sliding plate. The downward pressing screw is threadedly connected to the connecting frame. Rotating the downward pressing screw can make it move up and down on the connecting frame. The bottom of the downward pressing screw is connected to the downward pressing fixing plate through a bearing. When the downward pressing screw descends, it drives the downward pressing fixing plate to descend onto the sliding plate, and the cardboard can be clamped and fixed.

[0008] Further, a recycling box is provided below the adjusting port. The recycling box is used to collect the paper scraps generated after cutting, to prevent the paper scraps from falling everywhere and making the cutting place messy. An inclined structure is provided on one side of the recycling box to facilitate the diversion of the falling paper scraps. An opening is provided at the bottom of the recycling box. Placing objects such as trash cans and recycling bins below the opening can centrally recycle the cut paper scraps.

[0009] Further, the tail of the adjusting port is designed as an arc surface structure, which can prevent the cardboard from getting stuck at the adjusting port when being pushed forward.

[0010] Furthermore, the tail end of the frame is in an inclined plane structure, which is convenient for guiding the cut cardboard into the collection box.

[0011] The paper cutter for carton production of the utility model has the following beneficial effects:

[0012] 1. Through the cooperation of the limit plate, the downward pressing screw and the downward pressing fixing plate, the utility model can straighten, align and fix the cardboard, avoiding the problem that the cutting position is incorrect due to the skew of the cardboard during the pushing process.

[0013] 2. Through the cooperation of the limit plate and the transverse sliding groove, the utility model can slide according to the size of the cardboard, which is convenient for straightening and aligning cardboard of different sizes. By tightening the bolts on the limit posts, the limit plate is fixed in the transverse sliding groove to prevent the limit plate from sliding randomly when the cardboard is being straightened and aligned.

[0014] 3. By arranging a recycling box below the adjustment opening, the utility model can collect the paper scraps generated during the cutting of the cardboard, avoiding them from falling everywhere and making the cutting site messy. Through the inclined structure, the paper scraps are diverted to the opening and dropped into recycling containers such as trash cans and recycling bins for centralized recycling and treatment.
