Description

Technical Field

[0001] The utility model relates to the technical field of carton production, in particular to a knife cutting die for processing large packaging boxes. Background Art

[0002] In the field of packaging box processing, the processing of large packaging boxes usually requires the use of specially designed knife cutting dies. The main function of these dies is to cut, crease or shape cardboard or other materials during the manufacturing process of packaging boxes to meet different packaging needs. With the development of the logistics industry and the increase in cargo transportation, the demand for large packaging boxes is also growing. The traditional manual cutting method is inefficient and it is difficult to ensure the cutting quality and consistency. Therefore, the use of knife cutting dies has become an important means to improve production efficiency and product quality.

[0003] The existing knife-cutting molds for processing large packaging boxes have some problems during long-term use. In the existing use, the metal strips used to make indentations on the molds are relatively thick and in close contact with the edge lines. When the molds expand due to heat, the metal strips will be displaced, resulting in inaccurate edge positioning, thus affecting the quality of the packaging boxes. After long-term use, since the molds are mainly made of wooden boards, wood has certain shock-absorbing and buffering properties, which can reduce the impact force between the metal strips and the pressed materials, thereby reducing the risk of damage to the pressed materials. At the same time, compared with metal molds, wooden molds are usually lighter, easier to operate, carry and adjust, and during the indentation process of the equipment, the heated mold will expand, which will cause the metal strips on the mold to be displaced, resulting in inaccurate edge positioning, which will affect the processing accuracy and quality of the packaging boxes, increase the scrap rate and production costs. Utility Model Content

[0004] In view of the deficiencies in the prior art, the technical problem solved by the utility model is to provide a knife cutting die for processing large packaging boxes, so as to solve the problem that thermal expansion may cause displacement of metal strips, thereby causing inaccurate edge pressing positioning.

[0005] In order to solve the above problems, the technical solution adopted by the utility model is: a knife cutting mold for processing large packaging boxes, characterized in that: it includes a frame, a mounting seat is provided on the frame, a mold is fixedly provided on the mounting seat, a mounting bracket is fixedly provided on the mold, and a plurality of parallel horizontal bars are provided on one side of the mounting bracket, and the horizontal bars are fixedly connected to the mounting bracket; support bars are provided on both sides of the horizontal bars, and the support bars are fixedly connected to the mold, and the horizontal bars and the support bars on both sides are arranged in an arc-shaped structure; a gap is provided between the support bar and the horizontal bar.

[0006] The beneficial effect of this solution is that due to the gap between the support bar and the horizontal bar, the mold will not be hindered by the support bar when cutting the packaging box, thereby improving the cutting accuracy. Even if the mold expands due to heat, the horizontal bar will not be greatly affected, thereby ensuring the accuracy of the edge pressing and precise edge pressing positioning. The support bars on both sides of the horizontal bar are arranged in an arc-shaped structure. This design can not only further improve the accuracy of the edge pressing, but also avoid the horizontal bar being too thin and crushing the paper shell.

[0007] Furthermore, the mounting base is arranged in a roller structure, which can make it easier for the mounting base to maintain balance and stability when subjected to external forces, thereby reducing the possibility of tilting and shaking.

[0008] Furthermore, the mold and the mounting seat are connected by fastening screws. The fastening screw connection can reduce stress concentration at the connection between the mold and the mounting seat, extend the service life of the mold and the mounting seat, and by adjusting the tightening degree of the fastening screws, the tightness of the connection between the mold and the mounting seat can be accurately controlled, thereby achieving precise adjustment of the mold position and posture.

[0009] Furthermore, the mold is fitted on the surface of the mounting seat, and the surface of the roller structure is usually circular or cylindrical, which can provide a larger contact area, so that the mold can fit on the mounting seat more evenly, ensuring a close connection between the mold and the mounting seat, reducing gaps and errors, and the mold and the mounting seat surface of the roller structure fit well, which can improve the stability of the mold during use, reduce shaking and vibration, and improve processing accuracy and quality.

[0010] Furthermore, the horizontal bar is made of metal and is in an arc shape. The arc design enables the horizontal bar to apply pressure evenly during the indentation process. Compared with straight or other shaped horizontal bars, the arc shape can reduce the pressure concentration point and avoid local excessive pressure at the indentation, which may cause the material to rupture or deform. The uniform pressure distribution helps to produce clear and uniform indentations. The hardness and strength of the metal material ensure that the horizontal bar can stably press out precise marks when the roller rotates, so that the shape and depth of the indentation remain consistent, improving the quality and appearance of the product.

[0011] Furthermore, the support bar is arranged in an arc-shaped structure, which can evenly distribute the load on the support bar, reduce stress concentration points, and thus improve the overall strength and stability of the structure. This makes it less likely for the support bar to break or deform when bearing weight or external force.

[0012] Furthermore, the support bar is made of a soft rubber material, which is relatively soft and will not cause wear or scratches to the surface of the supported object.

[0013] Furthermore, a rotating cylinder is provided just above the mounting seat, and the rotating cylinder is cooperatively connected with the bracket, so that the paper shell passes through between the rotating cylinder and the mounting bracket, thereby improving the paper shell indentation efficiency.

[0014] Furthermore, the mold is made of wood, and the wood has a certain elasticity, which can provide a certain buffering effect during the process of roller rotation and mold pressing, which helps to reduce the impact and damage to the processed material. BRIEF DESCRIPTION OF THE DRAWINGS

The wood has a certain elasticity and can provide a certain buffering effect during the rotation of the mounting seat 1 and the pressing of the mold 4, which helps to reduce the impact and damage to the processed material. The mold 4 is attached to the surface of the mounting seat 1 to ensure the close connection between the mold 4 and the mounting seat 1 and reduce the gap.
