AI Technical Summary
In the prior art, partitions made of aluminum are prone to deform after being subjected to the pressure of the moving die, resulting in a short service life of the box splitter. In order to enhance the strength of the partition, the distance between adjacent cutting parts needs to be increased, resulting in an increase in the residual material of the cardboard.
The partition is made of a combination of thicker aluminum plates and thinner steel plates. The aluminum plate provides a wide support surface and the steel plate provides high strength and compressive resistance. The combination of the two not only meets the strength requirements of the partition, but also reduces the thickness of the partition and reduces the residual material of the cardboard.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of production tooling for packaging boxes, and particularly relates to a box separator for packaging boxes. Background Art
[0002] Rigid packaging boxes are generally made by folding rigid cardboard. The cutting die on a die-cutting machine cuts a raw cardboard sheet into cut pieces that can be folded into a box body. To improve production efficiency, the cutting die is provided with cutting lines for die-cutting multiple cutters at one time, so that multiple cut pieces can be cut out on a raw cardboard sheet at one time. Currently, to improve the utilization rate of the cardboard, it is desired that the distance between adjacent cut pieces be as small as possible during die-cutting.
[0003] After die-cutting, the raw cardboard sheet needs to enter a box separator for separating the cut pieces. Currently, the partitions for supporting the edges of the cut pieces in the box separator are generally made of aluminum because the shapes of the cut pieces are generally irregular, and aluminum has strong plasticity, which can be bent according to the shape of the cut piece to ensure effective support for the edges of the cut pieces.
[0004] When separating the cut pieces, the partition needs to bear a large downward pressure from the moving die. Since the partition supported by aluminum has low strength, it is easy to deform after being used for a period of time. To improve the service life of the box separator, the thickness of the partition needs to be increased, which in turn requires a sufficient distance between adjacent cut pieces, which will undoubtedly lead to an increase in cardboard waste. Summary of the Utility Model
[0005] Aiming at the above deficiencies of the prior art, the utility model provides a box separator for packaging boxes, which solves the problem that the thickness of the partition made of aluminum in the prior art is large, resulting in more cardboard waste.
[0006] To achieve the above object, the technical solution adopted by the utility model is as follows:
[0007] Provide a box separator for packaging boxes, which includes a support frame and partitions that divide the interior of the support frame into multiple collection chambers. The partitions include an aluminum plate and a steel plate fixedly connected in sequence from top to bottom, and the thickness of the steel plate is less than that of the aluminum plate.
[0008] The beneficial effect of the utility model is that during use, the moving die presses downward to press the cut pieces into the collection chambers. To buffer the impact force, the buffer spring in the moving die needs to contact the box separator.
[0009] The partition board in this solution is fixedly composed of a relatively thick aluminum plate and a relatively thin steel plate. The relatively thick aluminum plate can provide a wide enough support surface for the buffer spring in the moving die, while the steel plate has high strength, strong compressive resistance and anti-deformation ability, and can provide high enough support strength. The combined use of the two can not only meet the requirements for the support surface width and strength of the partition board, but also reduce the thickness of the partition board in the collection cavity part, providing necessary conditions for reducing the waste material of the cardboard.
[0010] Furthermore, connecting grooves are formed at the bottom of the aluminum plate, and the top of the steel plate extends into the connecting grooves. The steel plate is in close contact with the groove walls of the connecting grooves, which can enhance the connection strength between the aluminum plate and the steel plate.
[0011] Furthermore, the box separator further includes a box separating panel which is vertically fixed on the support frame. An inlet hole communicating with the collection cavity is formed on the box separating panel, and the aluminum plate is fixedly connected to the box separating panel. The box separating panel is used to provide a support surface for the buffer spring on the moving die.
[0012] Furthermore, the upper plane of the box separating panel and the aluminum plate are on the same horizontal plane. By setting like this, it is convenient for the spring of the moving die and the box separator to be in uniform contact on the same horizontal plane.
[0013] Furthermore, the box separator further includes a plurality of paper blocking blocks arranged around the inlet hole. The paper blocking blocks are detachably connected to the box separating panel. The paper blocking blocks can limit the left and right positions of the cutting parts and prevent the cutting parts stacked in the collection cavity from collapsing.
[0014] Furthermore, the paper blocking block includes a first connecting piece with a hollow interior and a second connecting piece arranged inside the first connecting piece; sliding grooves are formed on both sides inside the first connecting piece, and sliding bars are fixedly connected to both sides of the second connecting piece. The sliding bars are embedded in the sliding grooves to form a sliding fit. The second connecting piece can slide along the inside of the first connecting piece to make the overall length of the paper blocking block extend or shorten. After extension, more cutting parts can be accommodated.
[0015] Furthermore, a plurality of first connection holes are formed on the box separating panel, and round holes are formed at the top ends of the paper blocking blocks. The paper blocking blocks are bolted to the first connection holes. This is convenient for the disassembly and replacement of the paper blocking blocks.
[0016] Furthermore, at least one connecting column is fixedly connected to the top end of the paper blocking block, and a plurality of second connection holes are formed on the box separating panel. The connecting column extends into the second connection holes. The first function of setting the connecting column is to facilitate positioning. The connecting column can be first inserted into the second connection hole and then the bolt can be fixed. The second function is to provide at least two support points, which can limit the rotational freedom of the paper blocking block.
[0017] Further, an opening is provided on the side surface of the first connecting member with the largest surface area. After sliding down the second connecting member, it can extend into the first connecting member from the opening, facilitating the tightening or removal of the nut in the first connecting member.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0023] The following describes the specific embodiments of the present invention to facilitate those skilled in the art of this technology to understand the present invention. However, it should be clear that the present invention is not limited to the scope of the specific embodiments. For those of ordinary skill in the art of this technology, as long as various changes are within the spirit and scope of the present invention defined and determined by the appended claims, these changes are obvious, and all utility models created using the concept of the present invention are within the scope of protection.
[0024] As Figure 1-2 shown, the box separator of this solution includes a support frame 5 and a partition board 2 that divides the interior of the support frame 5 into multiple collection cavities 4. Some of the partition boards 2 are plates with a bending structure. The partition board 2 includes an aluminum plate 21 and a steel plate 22 fixedly connected in sequence from top to bottom, and the thickness of the steel plate 22 is less than that of the aluminum plate 21.
[0025] Since the upper plane of the partition board 2 needs to provide a sufficiently wide support surface for the buffer spring of the moving mold and sufficient support strength to prevent the partition board 2 from being collapsed by the cyclic load of the buffer spring after multiple stampings, the partition board 2 is preferably made of a relatively thick and high-strength metal plate. However, due to the relatively thick partition board, the distance between the cutting parts can only be set relatively far, which directly leads to a relatively wide edge waste material and an increase in waste.
[0026] When designing the structure of the box divider, it is hoped that the partition can be as thin as possible, but when the metal plate becomes thinner, not only the strength becomes worse, but also the supporting area becomes smaller, which does not meet the demand. In this regard, the partition 2 in this solution is fixedly combined with a thicker aluminum plate 21 and a thinner steel plate 22.
[0027] The thicker aluminum plate 21 provides a sufficiently wide support surface and sufficient support strength for the buffer spring, while the steel plate 22 has high strength, strong compression resistance and deformation resistance, and can provide sufficiently high support strength. The combination of the two can not only meet the strength requirements of the partition 2, but also reduce the thickness of the partition 2 located in the collection chamber 4, providing the necessary conditions for reducing the residual material of the cardboard.
[0028] The reason why the partition 2 made of aluminum is not used is that the thinner aluminum plate has low strength and obviously insufficient pressure resistance and deformation resistance. The reason why the partition 2 made of steel is not used is that the processability of steel is poor and the thicker steel plate 22 at the top is not easy to be bent and cannot be directly used as the partition 2.
[0029] The reason why the partition 2 needs to be bent is that the shape of the cut piece is a plane unfolded view of a box body. Due to the existence of the box cover and the bottom surface, the unfolded figure is not a rectangle with straight edges, but a heterogeneous part with a bent structure. In order to better fit the shape of the cut piece, the partition 2 needs to be bent to match the shape of the cut piece.
[0030] When implementing this solution, it is preferred to open a connection groove 23 at the bottom of the aluminum plate 21, and the top of the steel plate 22 extends into the connection groove 23, so that the steel plate 22 is in close contact with the groove wall of the connection groove 23. The connection groove 23 is preferably located at the bottom center of the aluminum plate 21.
[0031] This connection method increases the contact area between the aluminum plate 21 and the steel plate 22, thereby improving the connection strength. Specifically, after the steel plate 22 extends into the connection groove 23, it will be constrained in multiple directions by the groove wall of the aluminum plate 21, which helps prevent the steel plate 22 from displacement or rotation when subjected to force. At the same time, as the contact area between the steel plate 22 and the aluminum plate 21 increases, the friction between them also increases, thereby further improving the connection strength.
[0032] refer to Figure 1 and Figure 2 The box separator also includes a box separator panel 1, which is vertically fixed to the support frame 5. The box separator panel 1 is provided with an inlet hole 13 communicating with the collection chamber 4. The aluminum plate 21 is fixedly connected to the box separator panel 1. The box separator panel 1 is used to provide a support surface for the buffer spring on the movable mold. When pressed down, the buffer spring of the movable mold contacts the box separator panel 1, and the stamping assembly of the movable mold pushes the cutting piece into the collection chamber 4 from the inlet hole 13, and the cutting piece is stacked in the collection chamber 4.
[0033] The upper plane of the box-dividing panel 1 and the aluminum plate 21 is located on the same horizontal plane. By setting it like this, it is convenient for several buffer springs of the moving mold and the box-divider to be evenly in contact on the same horizontal plane. And the partition 2 also divides the inlet hole 13 into several special-shaped holes, and the shape of each special-shaped hole matches the shape of the cutting piece, which helps the box-dividing panel 1 to support all the remaining material parts, and the cutting piece part is suspended, and only the cutting piece bears the pressure of the stamping assembly of the moving mold, so as to quickly peel the cutting piece from the raw cardboard.
[0034] The box-divider further includes several paper-blocking blocks 3 arranged around the inlet hole 13. The paper-blocking blocks 3 can be strip-shaped structures, and the paper-blocking blocks 3 are detachably connected to the box-dividing panel 1. The setting of the paper-blocking blocks 3 can limit the cutting piece left and right to prevent the stacked cutting pieces in the collection cavity 4 from collapsing.
[0035] Reference Figure 3 and Figure 4 In one embodiment, the paper-blocking block 3 includes a first connecting piece 31 with a hollow interior and a second connecting piece 32 arranged inside the first connecting piece 31; both sides inside the first connecting piece 31 are provided with sliding grooves 33, and both sides of the second connecting piece 32 are fixedly connected with sliding strips 34, and the sliding strips 34 are embedded in the sliding grooves 33 and form a sliding fit. The second connecting piece 32 can slide along the inside of the first connecting piece 31 to make the overall length of the paper-blocking block 3 extend or shorten, and more cutting pieces can be accommodated after extension.
[0036] Preferably, a limiting block is provided at the top end of the second connecting piece 32, and a baffle for preventing the limiting block from moving downward is provided at the end of the first connecting piece 31, and the connection between the sliding strip 34 and the sliding groove 33 is tight enough to prevent the second connecting piece 32 from directly detaching from the first connecting piece 31 due to gravity.
[0037] In actual use, the paper-blocking block 3 is suspended and does not need to provide support for the box-dividing panel 1, so a locking mechanism may not be provided between the first connecting piece 31 and the second connecting piece 32.
[0038] Reference Figure 1 On the box-dividing panel 1, several first connecting holes 11 are opened, round holes are opened at the top end of the paper-blocking block 3, and the paper-blocking block 3 is bolted to the first connecting holes 11. It is convenient for the disassembly and replacement of the paper-blocking block 3. Preferably, the round hole can be located at the top end of the first connecting piece 31, the tail of the bolt passes through the first connecting hole 11 and the round hole in sequence, and the nut is fixed inside the first connecting piece 31.
[0039] An opening 36 is opened on the side surface of the first connecting piece 31 with the largest surface area. After the second connecting piece 32 slides down, it can extend into the inside of the first connecting piece 31 from the opening 36, which is convenient for tightening or disassembling the nut in the first connecting piece 31.
[0040] At least one connecting column 35 is fixedly connected to the top end of the paper blocking block 3, and a plurality of second connecting holes 12 are formed in the sub-box panel 1, and the connecting column 35 extends into the second connecting holes 12. One function of setting the connecting column 35 is to facilitate positioning. The connecting column 35 can be first inserted into the second connecting hole 12 and then the bolt is fixed. The second function is to provide at least two support points, which can limit the rotational freedom of the paper blocking block 3. Preferably, the connecting column 35 is arranged at the top end of the first connecting member 31 and can be integrally formed with the first connecting member 31.
[0041] In summary, the partition 2 in this solution can not only meet the requirements for the support surface width and strength of the partition 2, but also reduce the thickness of the partition 2 in the collection cavity 4 part, providing a necessary condition for reducing the waste material of the cardboard.
