Description

TECHNICAL FIELD

[0001] The present application relates to the field of packaging bag edge cutting, in particular to a kind of for desiccant packaging bag processing edge cutting collection device. BACKGROUND

[0002] Packaging bag edge cutting refers to the process of trimming the edges of packaging bags. When processing silica gel desiccant packaging bags, it is necessary to ensure that the silica gel desiccant packaging bags meet the specified length, width and shape requirements, so as to better adapt to the product packaging needs and improve the aesthetics and consistency of the packaging. In the process of making silica gel desiccant packaging bags, there may be rough edges, irregular edges or excess material. Edge cutting can remove these parts to make the edges of the packaging bags neat and smooth. Neat edges can reduce the likelihood of breakage, leakage and other problems during use of the packaging bags, and also facilitate subsequent sealing, printing and other processing procedures. The size of the cut packaging bag should meet the design requirements, and the tolerance range is usually small to ensure the tightness and stability of the packaging. When cutting the edges of silica gel desiccant packaging bags, the commonly used pulverizing tool is a sharp tool such as a flat knife or a round knife, which directly pulverizes the packaging bags. This method is suitable for relatively thin packaging materials such as silica gel desiccant packaging bags, and is simple to operate and low in cost. The packaging bags are placed on a die cutting machine for stamping and pulverizing by a custom-made die. Die cutting can achieve complex edge cutting with high precision.

[0003] During the cutting process of silica gel desiccant packaging bags, a large amount of residual material is generated. These residual materials are often irregular in shape and size. When collecting the residual material after cutting, the residual material exists in a large volume. As the cutting residual material continues to accumulate, it occupies a large space in the collection device, making it difficult for the collection device to accommodate more residual material, resulting in waste of space.

Under the action of the meshing connection of the two gears 17, the two gears 17 can respectively drive the two rotating rods to rotate, and the two rotate in opposite directions. Since the two sets of crushing knives A402 are staggered, the residual materials of the packaging bag can be cut more effectively when performing the cutting action.

[0034] Working principle:

[0035] First, install the whole and the silica gel desiccant packaging bag trimming device, and discharge the residual materials after trimming the packaging bags to the upper end of the upper collection box, and the trimming residual materials enter the middle of the collection box from the upper end of the collection box, and the two sets of crushing knives A402 are set in the middle of the collection box. At this time, the residual materials reach the two sets of crushing knives A402, and are connected to the rotating rod A401 through an external motor, and drive the rotating rod A401 to rotate. The rotating rod A401 drives one of the gears 17 to rotate, that is, the gear 17 fixed to the rotating rod A401. Since the two gears 17 are engaged and connected, when one of the gears 17 rotates, the other gear 17 rotates accordingly, and the other gear 17 drives the other rotating rod A401 to rotate. At this time, the two rotating rods A401 rotate synchronously, and the two rotating rods A401 respectively drive the two sets of crushing knives A402 to rotate, and the two sets of crushing knives A4 02 During the rotation process, since the two sets of crushing knives A402 are staggered, they can act on the packaging bag from different angles at the same time when cutting, just like the two blades of scissors, cooperating with each other to apply crushing force together. This synergistic effect enhances the crushing force and can more effectively cut the material of the packaging bag. Moreover, due to the staggered setting, the number of contact points between the crushing knife A402 and the packaging bag increases. Compared with a single crushing knife, multi-point contact can disperse the crushing force to different parts of the packaging bag in a shorter time, thereby improving the efficiency and effect of crushing. For packaging bags with uneven materials or multi-layer structures, the staggered crushing knives can apply different crushing forces at different parts, thereby achieving more uniform crushing. This uniform crushing can reduce the breakage and damage of the packaging bag during the cutting process, thereby improving the quality and reliability of the product.

[0036] Next, by setting the crushing blade A402 to be elliptical, the elliptical crushing blade A402 can provide a larger contact area when contacting the packaging bag during the crushing process compared to traditional straight or other shaped crushing blades. This means that under the same crushing pressure, the elliptical crushing blade A402 can distribute the crushing force more evenly, making the packaging bag crushing smoother and reducing the situation of packaging bag breakage or deformation caused by local excessive force. The elliptical shape allows the crushing blade A402 to form a continuously changing crushing angle when cutting. During the crushing process, different parts of the packaging bag can be appropriately adjusted to the most appropriate crushing angle according to their thickness and material, thereby improving crushing efficiency and quality. For example, for thicker parts of the packaging bag, the crushing blade can cut at a larger angle, while for thinner parts, it can be crushed at a smaller angle to ensure that the entire packaging bag can be accurately cut. The edge of the elliptical crushing blade A402 needs to be set to be relatively smooth, which can reduce the friction and resistance between the crushing blade and the packaging bag during the crushing process, compared to sharp straight lines. The oval-shaped crushing blade A402 saves more effort during crushing, which can reduce the energy consumption of the equipment. It also reduces the wear of the crushing blade A402 and extends its service life. It should be noted that the oval shape of the crushing blade A402 has certain structural advantages. It can better withstand the stress and impact force during the crushing process. Compared with crushing blades of other shapes, the oval crushing blade has higher strength and rigidity and is not prone to deformation or damage. This is especially important for long-term high-intensity crushing operations. It can ensure the stability and reliability of the crushing blade, reduce equipment maintenance costs, and facilitate installation and fixation. Oval-shaped crushing blades usually have a more regular shape, which makes them more convenient to install and fix to the equipment. A standardized installation method can be used to ensure the accurate position of the crushing blade A402, improving the assembly accuracy and production efficiency of the equipment. At the same time, the oval-shaped crushing blade A402 is fixed more firmly and is not prone to loosening or shifting during operation, ensuring the accuracy and stability of crushing. The crushing blade A402 ultimately crushes the residual material into strips.

[0037] Then, the strip-shaped residue enters the bottom of the upper collection box, which is the area of ​​the crushing knife B502. The rotating rod B501 is driven by an external motor to rotate, and the rotating rod B501 drives the crushing knife B502 to rotate. Since the crushing knife B502 is spiral, the spiral crushing knife B502 can continuously crush the strip-shaped residue during the rotation process. Due to its spiral shape, the crushing knife B502 will contact the residue multiple times during one rotation, achieving multiple crushing. Compared with the traditional linear crushing knife, this continuous crushing method greatly increases the frequency and efficiency of crushing, and can be more The strip residue is quickly cut into fragments, achieving the purpose of crushing the residue. It should be noted that the spiral structure of the spiral crushing knife B502 makes the crushing process gradual. When the strip residue enters the crushing area, it will first be gradually cut into by the edge of the spiral crushing knife B502. As the residue continues to move forward, the crushing depth gradually increases, and finally the residue is completely cut off. This progressive crushing method can better control the size and direction of the crushing force, reduce the deformation and breakage of the residue during the crushing process, thereby ensuring that the shape of the crushed fragments is more regular, which is convenient for subsequent collection.

[0038] It should be noted that before shredding, trimmings are typically large, lumpy objects with a certain length, width, and height. After shredding, the trimmings are broken into smaller particles, the total volume of which is significantly smaller than the original bulk. Due to their smaller size, the shredded trimmings can be packed more densely, with fewer gaps between particles, reducing the overall space occupied. Under the action of gravity, the small particles automatically fill the gaps between larger particles, forming a more compact stacking structure. This compact stacking can greatly improve space utilization. For example, on construction sites, shredded sand can be packed more tightly together after shredding, reducing the space required for stacking. Shredded trimmings are typically compressible. When subjected to external pressure, the gaps between particles can be further reduced, further reducing the volume of the trimmings. For example, in waste disposal, shredded waste can be compressed using compression equipment to reduce the space it occupies. Unshredded trimmings, on the other hand, are larger and less compressible, making them difficult to compress effectively.

[0039] Then, the crushed trimming residue enters the lower collecting shell 3 from the upper collecting shell 2, and then the motor drives the driving shaft 703 to rotate, the driving shaft 703 drives the chassis 702 to rotate, and the chassis 702 drives the rotating mechanism 7 to rotate as a whole. At this time, the several curved plates 22 in the rotating mechanism 7 start to rotate, throwing the crushed residue outward, so that the residue fits the elastic air bag and accumulates on the outside of the curved plate 22. As the residue continues to increase, the curved plate 22 accumulates the residue. When the thickness of the accumulation is greater than the distance between the curved plate 22 and the elastic air bag, the curved plate 22 will squeeze the residue so that the residue can be tightly compacted, thereby improving the space utilization rate. As the accumulation thickness becomes larger and larger, these accumulated residues will squeeze the curved plate 22 to rotate around the rotating shaft 8. At this time, the area formed by multiple curved plates 22 is reduced, providing more space for the residue, and ensuring that the curved plate 22 can continue to compact the residue, thereby improving the space utilization rate.

[0040] Then, as the amount of residual materials increases, it indicates that the crushing blade A402 and the crushing blade B502 have been working for a long time. At this time, some impurities will adhere to the crushing blades A402 and B502 due to the long-term work, affecting the subsequent crushing work. Therefore, the elastic airbag is compressed under the squeezing of the arc plate 22 and the residual materials, so that the internal pressure thereof increases. The increased pressure is transmitted to the piston 162 through the through hole 11 and the fixed cylinder 12, causing the piston 162 to move, and the spring 163 begins to stretch and accumulate force. The piston 162 drives the seal 161 to move, and the seal 161 breaks away from the seal of the inlet pipe 13 and the outlet pipe 14, opening the two. The air pump inputs gas, and the gas passes through the air inlet pipe 13, the fixed cylinder 12, the air outlet pipe 14, the long cylinder 151 and several nozzles 152 in sequence. The several nozzles 152 blow air to the crushing knife A402 and the crushing knife B502 to remove the residue on their surface. As the residue in the lower collecting shell 3 increases, the crushing knife A402 and the crushing knife B502 are more likely to adhere to more foreign matter. At this time, the pressure of the curved plate 22 and the residue on the elastic airbag is greater, so the degree to which the seal 161 is separated from the air inlet pipe 13 and the air outlet pipe 14 is greater, which increases the exhaust volume, thereby improving the cleaning effect. Finally, when it is necessary to discharge from the residue, it is only necessary to disassemble the chassis 702.
