Description

Technical Field

[0001] The utility model relates to the field of plate cutting devices, in particular to a cutting device for packaging mother boards. Background Art

[0002] Existing packaging boxes are mainly made of multiple packaging motherboards that are cut and assembled with other packaging boards to complete the packaging box and the goods. When packing some specific goods, such as the packing of non-woven fabric rolls that have been rolled up, unlike the packing of conventional goods, the quantity is generally small, and it is impossible to prepare a large number of packaging boxes or their components for a long time, so that the goods can be packed in time when needed. Under normal circumstances, the packaging box components are usually cut and assembled temporarily according to needs. However, in an existing packaging box that is not easy to deform and can relatively well protect the goods, as mentioned above, it is completely impossible to prepare packaging box materials according to actual conditions during use, but the packaging box must be packed in time when there is a need for use. In particular, the packaging motherboard must be cut before it can be used normally. How to quickly and efficiently cut the required packaging motherboard determines the efficiency of the packaging box assembly and the overall goods packing. Summary of the invention

[0003] The utility model aims to provide a packaging mother board cutting device which has a simple structure and can cut out packaging mother boards quickly and efficiently.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions: a packaging motherboard cutting device, including a mounting frame and a cutting knife group, the cutting knife group is installed on the mounting frame, the cutting knife group includes a matching plate fixedly connected and matched with the mounting frame, and a cutting plate located above the matching plate, the cutting plate is connected and matched with the mounting frame and driven by a driving motor to move up and down relative to the matching plate, a pair of symmetrically arranged cutting knife grooves are opened on the lower surface of the cutting plate, a cutting knife is fixedly arranged in the cutting knife groove, and the cutting knife blade is exposed under the cutting plate The surface surrounds the folding plate shape formed after the packaging mother board is cut, and a working groove for the cutting knife blade to enter and exit is opened on the matching plate corresponding to the cutting knife blade position, and a pair of symmetrically arranged limit blocks with limiting planes are provided at the same position at the same end of the corresponding working groove on the matching plate, and the angle formed between the positions of the limiting planes of the limit blocks is in the range of 60°-150°. After the packaging mother board part enters the upper surface position of the matching plate, the two side edges of the packaging mother board are fitted with the limiting planes of the limiting blocks, and the cutting knife blade extends from the position of the limiting plane of the limiting block to the center position of the packaging mother board.

[0005] Furthermore, the packaging motherboard is a rectangular or square paper foldable hard board, and the blade of the cutting knife extends from the limiting plane of the limiting block to the center of the packaging motherboard after the limiting is completed, and the cutting knife blade includes a first blade extending from the limiting plane of the limiting block to the center of the packaging motherboard after the limiting is completed, a second blade whose head end is connected to the end of the first blade and extends to the center of the packaging motherboard after the limiting is completed, and a third blade whose head end is connected to the end of the second blade and extends to the center of the packaging motherboard after the limiting is completed. The lengths of the first blade, the second blade and the third blade are equal, and the angle between the first blade and the limiting plane of the limiting block is in the range of 30°-60°, the second blade is perpendicular to the limiting plane of the limiting block, and the third blade is parallel to the limiting plane of the limiting block.

[0006] Furthermore, a horizontal punching knife is provided between the two cutting knives, and both ends of the punching knife are close to the third blade. A punching groove is provided on the matching plate corresponding to the position of the punching knife, and a discharge port is provided at the lower part of the matching plate connected to the punching groove for discharging waste materials punched out after punching.

[0007] Furthermore, a top block is arranged in the working groove, the side wall of the top block does not conflict with the inner wall of the working groove, and the minimum distance between the side wall of the top block and the inner wall of the working groove is greater than the maximum thickness of the cutting knife blade.

[0008] Furthermore, the top of the top block is flush with the notch of the working groove.

[0009] The beneficial effects of the utility model are as follows: the utility model cuts the packaging mother board on the matching plate and cuts out the required folding plate shape by the cutting knife on the cutting plate moving up and down relative to the matching plate entering and exiting the working groove on the matching plate. The overall up and down movement of the cutting plate is simple and error-prone. The cutting cooperation between the cutting knife blade and the inner wall of the working groove makes the cutting action of cutting the packaging mother board simpler and more efficient, and the cutting position of the packaging template is not easy to deform. When there is an application demand for packaging boxes and packaging mother boards, the packaging mother boards can be cut quickly and efficiently according to the temporary use requirements of the packaging mother boards, and the overall packaging and assembly of the packaging boxes can be carried out in time, avoiding the problem that the packaging boxes cannot be quickly assembled according to the use requirements due to the inability to have a large number of spare parts for a long time, reducing the pressure on the spare parts of the packaging boxes, and reducing the application cost.

[0014] In order to make the technical means, innovative features and functions implemented by the utility model easy to understand, the utility model will be further described below.

[0015] like Figure 1-4 As shown, the technical solution of the packaging motherboard cutting device of the utility model includes a mounting bracket and a cutting knife group, the cutting knife group is installed on the mounting bracket, the cutting knife group includes a matching plate 1 fixedly connected and matched with the mounting bracket, and a cutting plate 2 located above the matching plate 1, the cutting plate 2 is connected and matched with the mounting bracket and driven by a driving motor to move up and down relative to the matching plate 1, a pair of symmetrically arranged cutting knife grooves are opened on the lower surface of the cutting plate 2, a cutting knife 3 is fixedly arranged in the cutting knife groove, and the blade of the cutting knife 3 is exposed on the lower surface of the cutting plate 2 and surrounds the packaging motherboard The shape of the folded plate is formed after cutting. A working groove 4 for the cutting knife 3 blade to enter and exit is opened on the matching plate 1 corresponding to the cutting knife 3 blade position. A pair of symmetrically arranged limit blocks 5 with limiting planes are provided at the same position at the same end of the matching plate 1 corresponding to the working groove 4. The angle formed between the positions of the limiting planes of the limit blocks 5 is in the range of 60°-150°. After the packaging mother board part enters the upper surface position of the matching plate 1, the two side edges of the packaging mother board are fitted with the limiting planes of the limit blocks 5, and the cutting knife 3 blade extends from the position of the limiting plane of the limit block 5 to the center position of the packaging mother board.

[0016] In the production process of non-woven fabric rolls, generally, relatively more packaging boxes use hard cardboard for packaging and protection of the outside of the non-woven fabric rolls, that is, the packaging mother board is a rectangular or square paper foldable hard board, and the blade of the cutting knife 3 extends from the limiting plane of the limiting block 5 to the center of the packaging mother board corresponding to the packaging mother board after the limiting is completed, and the blade of the cutting knife 3 includes a first blade extending from the limiting plane of the limiting block 5 to the center of the packaging mother board after the limiting is completed, a second blade connected to the end of the first blade at the head end and extending to the center of the packaging mother board after the limiting is completed, and a third blade connected to the end of the second blade at the head end and extending to the center of the packaging mother board after the limiting is completed. The lengths of the first blade, the second blade and the third blade are equal, and the angle between the first blade and the position of the limiting plane of the limiting block 5 is in the range of 30°-60°, the second blade is perpendicular to the position of the limiting plane of the limiting block 5, and the third blade is parallel to the position of the limiting plane of the limiting block 5. The position design of the three blades enables the overall cutting device to easily cut a cutting seam that meets the use requirements of the packaging box, greatly reducing the cutting difficulty and the requirements for cutting accuracy, and reducing the application cost of the overall packaging box.

[0017] When the structural strength of several folding positions of the packaging box needs to be strengthened, especially when the structural strength of the four corners at the top and bottom is insufficient, the more commonly used method is to locally thicken the corners. In order to be able to partially fold the folding plate at the four right-angle folding positions of the packaging mother board, such as Figure 2-4 As shown, a horizontal strip punching knife 7 is provided between the two cutting knives 3, and the two ends of the punching knife 7 are close to the third blade. A punching slot 8 is provided on the matching plate 1 corresponding to the position of the punching knife 7. The lower part of the matching plate 1 is connected to the punching slot 8 and has a discharge port 9 for the waste material punched out after punching. Through the cooperation of the punching knife 7 and the punching slot 8, a horizontal strip limiting hole is cut to limit the folding plate part after folding and complete the local thickening, so that the structural strength of the position of the packaging box that is easily deformed by force after the combined assembly is higher and not easy to deform, and the packaging box as a whole is more solid and durable. Figure 4 As shown, a preferred embodiment of a packaging motherboard 10 is cut and formed, and then wrapped with waterproof oily packaging paper to serve as the upper packaging cover and the lower packaging cover of the packaging box. The assembly of the packaging box can be completed by assembling the side box of the packaging box, and the packaging speed is fast and the efficiency is high.

[0018] When the cutting seam is actually cut, since the packaging mother board is cut directly by the cutting knife 3, the packaging mother board may inevitably be deformed, and even the packaging mother board may be damaged as a whole. Therefore, in order to reduce the deformation and even possible damage and breakage of the packaging mother board during the cutting process, Figure 1-3 As shown, a top block 6 is also arranged in the working groove 4, and the side wall of the top block 6 does not conflict with the inner wall of the working groove 4, and the minimum distance between the side wall of the top block 6 and the inner wall of the working groove 4 is greater than the maximum thickness of the blade of the cutting knife 3, and the top of the top block 6 is flush with the notch of the working groove 4. The above-mentioned design uses the top block 6 to limit the packaging mother board without affecting the cutting work of the cutting knife 3 to directly perform the cutting work of the packaging mother board, thereby reducing the possibility that the packaging mother board will be locally deformed after being subjected to force during the cutting process and then enter the working groove 4 and then be deformed or even damaged, thereby improving the yield rate of the process of cutting the packaging mother board and reducing the application cost of the overall packaging box.

[0019] Although the utility model has been disclosed as above in terms of specific embodiments, it is not intended to limit the utility model. Any technician in this field can make slight changes and modifications without departing from the spirit and scope of the utility model. Therefore, the scope of protection of the utility model should be determined by the scope of the attached claims.
