Description

Technical Field

[0001] This utility model relates to the technical field of packaging carton processing equipment, and in particular to a cutting structure and cardboard cutting system. Background Technology

[0002] Corrugated cardboard is the main material for packaging cartons. During the packaging carton processing, the cardboard needs to be cut into different sizes to produce packaging cartons of different specifications. In existing technology, conveyor belts are generally used to transfer the cardboard between different processes (or between different positions within the same process). Cutting can be carried out between two adjacent conveyor belts. For example, a cutting blade can be set above the two conveyor belts near each other. The cutting blade is driven up and down by a telescopic device (such as a cylinder). When the cardboard is below the cutting blade, the cutting blade moves downward to achieve cutting. During cutting, the conveyor belt often needs to be stopped to ensure smooth cutting. After cutting, the next conveyor belt is started to remove the cut portion, and then the previous conveyor belt is started again to push the remaining portion onto the next conveyor belt. This process is relatively cumbersome, and the overall efficiency cannot be further improved. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a cutting structure that solves the problem that the overall efficiency cannot be further improved because the front and rear conveyor belts need to be started sequentially.

[0004] According to an embodiment, a cutting structure is provided, which includes a first conveyor belt and a second conveyor belt arranged sequentially, and a mounting plate arranged above each other at close proximity. A first telescopic member and a second telescopic member are fixedly mounted on the mounting plate. The first telescopic member has a downwardly extending first output end and a cutting blade is connected to the first output end. The second telescopic member has a downwardly extending second output end and a pressure plate is connected to the second output end. The pressure plate is located above the first conveyor belt and can press down against the first conveyor belt. A pair of vertical plates located on both sides of the first and second conveyor belts at close proximity are also fixedly connected below the mounting plate. A support plate is fixedly connected to the upper end of the two vertical plates, and the support plate has a top surface flush with the upper surface of the first conveyor belt. The cutting blade can press down against the support plate. The upper surface of the second conveyor belt is lower than the top surface of the support plate. This design incorporates a cutting blade and a support plate between the first and second conveyor belts. During operation, the first conveyor belt carries the cardboard through the space between the support plate and the cutting blade onto the second conveyor belt. The upper surface of the second conveyor belt is slightly lower than the top surface of the support plate. Initially, the end of the cardboard does not directly contact the second conveyor belt but continues forward under the influence of the first conveyor belt. Then, under gravity, it falls onto the second conveyor belt. When the cutting position is almost directly below the cutting blade, the pressure plate moves downwards and presses the cardboard onto the first conveyor belt (at which point the first conveyor belt also stops). The pressure plate holds the cardboard in place while simultaneously... This design lifts the other end of the cardboard away from the second conveyor belt, preventing it from being pulled by the second conveyor belt. This ensures the cardboard remains stable during the cutting process. The cutting blade moves downwards to cut the cardboard. After cutting, the cardboard falls and contacts the second conveyor belt, allowing it to continue moving forward under the drive of the second conveyor belt. Then, the cutting blade returns upwards, the first conveyor belt starts, and the next cycle begins. During this process, the second conveyor belt can run continuously. Only the first conveyor belt needs to be turned on and off, making the process simpler and improving overall efficiency. This solves the problem in existing technologies where the front and rear conveyor belts need to be started sequentially, which prevents further improvement in overall efficiency.

[0005] Furthermore, the pallet has an arc-shaped surface on the side near the second conveyor belt. The arc-shaped surface has a higher side and a lower side. The higher side is in contact with the top surface of the pallet, and the lower side is close to and higher than the upper surface of the second conveyor belt.

[0006] Furthermore, a vertical through frame extending along the length of the pallet is provided on the top surface of the pallet, into which the cutting blade can be inserted.

[0007] Furthermore, the width of the top edge of the frame gradually decreases from top to bottom.

[0008] Furthermore, the upper ends of the two vertical plates also have portions that extend beyond the support plate.

[0009] Furthermore, the first telescopic device is fixedly installed on the surface of the mounting plate, and the first output end extends through the mounting plate and is fixedly connected to the cutting blade. The second telescopic device is fixedly installed on the lower surface of the mounting plate.

[0010] Furthermore, a connecting sleeve is fitted onto the end of the second telescopic end, and the connecting sleeve is fixed to the upper plate surface of the pressure plate.

[0011] Furthermore, inclined plates extending outward and upward are fixedly connected to the side of the pressure plate near the second conveyor belt and the side away from the second conveyor belt, respectively.

[0012] According to an embodiment, a cardboard cutting system including the above-described cutting structure is also provided.

[0013] Compared with the prior art, the present invention has the following beneficial effects: By setting the second conveyor belt slightly lower, it can continue to run without needing to be stopped and restarted. Only the first conveyor belt needs to be turned on and off, making the process simpler and improving overall efficiency. This solves the problem in the prior art where the front and rear conveyor belts need to be started sequentially, which prevents further improvement in overall efficiency.

[0015] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0016] like Figure 1-4As shown, this embodiment provides a cardboard cutting system, similar to existing technologies, with a cutting structure. Specifically, the cutting structure includes a first conveyor belt 1 and a second conveyor belt 2 arranged sequentially, and a mounting plate 3 positioned above and between them. A first telescopic device 4 is fixedly mounted on the mounting plate 3. Unlike existing technologies, a second telescopic device 5 located above the first conveyor belt 1 is also fixedly mounted on the mounting plate 3. Both the first telescopic device 4 and the second telescopic device 5 can be cylinders. The first telescopic device 4 is fixed above the mounting plate 3 and has a first output end that extends downwards through the mounting plate 3, with a cutting blade 6 fixedly connected to the end of the first output end. The second telescopic device 5 is fixedly mounted on the lower surface of the mounting plate 3 and has a second output end extending downwards. At the second output end, a connecting sleeve 7 is fixedly sleeved on the end, and a pressure plate 8 is fixedly connected to the connecting sleeve 7. An outwardly extending inclined plate 9 is fixedly connected to the side of the pressure plate 8 near the second conveyor belt 2 and the side away from the second conveyor belt 2, respectively. The pressure plate 8 can move up and down above the first conveyor belt 1 during the operation of the second telescopic device 5, so that the cardboard 11 can be pressed onto the upper surface of the first conveyor belt 1. The cutting blade 6 is located between the first conveyor belt 1 and the second conveyor belt 2. A support plate 10 is also fixedly installed between the first conveyor belt 1 and the second conveyor belt 2, located directly below the cutting blade 6, to limit the cutting blade 6. The top surface of the support plate 10 is flush with (or slightly lower than) the upper surface of the first conveyor belt 1. The upper surface of the conveyor belt 2 is lower than the top surface of the pallet 10. During operation, the first conveyor belt 1 carries the cardboard 11 through the pallet 10 and the cutting blade 6 onto the second conveyor belt 2. The upper surface of the second conveyor belt 2 is slightly lower than the top surface of the pallet 10. Initially, the end of the cardboard 11 does not directly contact the second conveyor belt 2, but continues forward under the influence of the first conveyor belt 1, and then falls onto the second conveyor belt 2 under gravity. When the cutting position is almost directly below the cutting blade 6, the pressure plate 8 moves downwards and presses the cardboard 11 onto the first conveyor belt 1 (at which point the first conveyor belt 1 also stops). The pressure plate 8 presses down on the cardboard 11, simultaneously causing the other end of the cardboard 11 to lift off the second conveyor belt 2 and become unaffected by it. Pulling ensures the cardboard 11 remains stable during the cutting process. The cutting blade 6 moves downward to cut the cardboard. After cutting, the cardboard 11 falls and contacts the second conveyor belt 2, thus continuing forward under the drive of the second conveyor belt 2. Then the cutting blade 6 returns upward, the first conveyor belt 1 starts, and the next round begins. During this process, the second conveyor belt 2 can be continuously running. Only the first conveyor belt 1 needs to be turned on and off. The opening and closing operation of the first conveyor belt 1 is similar to that in the prior art. However, the second conveyor belt 2 of this application does not need to be turned on and off in the same way as in the prior art. Therefore, the steps are relatively simpler, and the overall efficiency can be improved accordingly. This solves the problem that the overall efficiency cannot be further improved because the front and rear conveyor belts need to be started sequentially in the prior art.In actual operation, to ensure smoother cutting, the first conveyor belt 1 can be stopped early, specifically when the cardboard 11 contacts the pallet 10. Then, the operator manually pushes the belt to align the cutting position with the cutting blade 6 (i.e., the cutting position is directly below the cutting blade 6). The pressure plate 8 then descends to hold the cardboard 11 in place. After cutting, the cutting blade 6 moves upward, and the second telescopic device 5 is activated to move the pressure plate 8 upward (similar to existing technologies, both the first telescopic device 4 and the second telescopic device 5 can be cylinders).

[0017] like Figure 1-4 As shown, in a further embodiment, the pallet 10 has an arc-shaped surface 12 on the side near the second conveyor belt 2. The arc-shaped surface 12 has a higher side and a lower side, with the higher side connected to the top surface of the pallet 10 and the lower side close to and higher than the upper surface of the second conveyor belt 2. After cutting, the end of the cardboard 11 can move downwards at a gentle angle through the arc-shaped surface 12. Furthermore, vertical plates 13 are fixedly connected to both ends of the pallet 10. The two vertical plates 13 are located on both sides of the first conveyor belt 1 and the second conveyor belt 2 to stabilize the pallet 10. The pallet 10 also has a length-length... The vertical through frame 14 extends in the direction of cutting. The through frame 14 is located directly below the cutting blade 6. After the cutting blade 6 cuts the cardboard 11 downwards, it can partially enter the through frame 14 to ensure complete cutting. At the same time, it also protects the cutting blade 6 from directly hitting the pallet 10 and causing impact. More specifically, the width of the upper end of the through frame 14 gradually decreases from top to bottom, so that the cutting blade 6 can enter the upper end of the through frame 14 without contacting the side wall of the through frame 14. The upper end of the vertical plate 13 is located above the pallet 10, which can provide blocking and limiting on both sides of the cardboard 11 to prevent the cardboard 11 from deviating seriously on both sides and falling outside the side of the second conveyor belt 2.

[0018] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
