Description

Technical Field

[0001] The invention relates to the field of packaging bag edge trimming, in particular to an edge trimming and collecting device for desiccant packaging bags. Background Art

[0002] The trimming of packaging bags refers to the process of trimming the edges of packaging bags. When processing silica gel desiccant packaging bags, ensure that the silica gel desiccant packaging bags meet the specified length, width and shape requirements, so as to better meet the product packaging needs and improve the aesthetics and consistency of the packaging. In the production process of silica gel desiccant packaging bags, there may be burrs, irregular edges or excess materials. Trimming can remove these parts to make the edges of the packaging bags neat and smooth. Neat trimming can reduce the possibility of problems such as rupture and leakage during use of the packaging bags, and it is also convenient for subsequent sealing, printing and other processing procedures. The size of the packaging bag after trimming should meet the design requirements, and the tolerance range is usually small to ensure the tightness and stability of the packaging. When trimming the silica gel desiccant packaging bags, the commonly used crushing tool is to use a sharp tool, such as a flat knife, a round knife, etc., to directly crush the packaging bag. This method is suitable for thinner packaging bag materials such as silica gel desiccant packaging bags, with simple operation and low cost. Through a customized mold, the packaging bag is placed on a die-cutting machine for stamping and crushing. Die-cutting can achieve trimming of complex shapes with high precision.

[0003] In the process of trimming the silica gel desiccant packaging bag, the trimming operation will generate a large amount of residues, which are often irregular in shape and size. When the residues after trimming are collected, these residues will exist in a larger volume. As the trimming residues continue to accumulate, they occupy a larger space in the collection device, making it difficult for the collection device to accommodate more residues, resulting in a waste of space. At the same time, in order to store these residues, additional collection devices may be required, which undoubtedly increases production costs. Summary of the invention

As the residue increases, on the one hand, the arc plates can automatically adjust their angles to adapt to the accumulation amount of the residue and provide more space for the residue. On the other hand, the arc plates always compact the residue tightly. As the residue increases, the crushing blades A and B will also adhere to more foreign matter. Through the airbag, the pressure applied by the arc plate to the residue will be transmitted to the airbag, compressing the airbag, thereby causing the sealing structure to open the ventilation channel and use gas for cleaning. The larger the amount of residue, the greater the squeezing force, the greater the rate of gas ejection, and thus the better the cleaning effect. BRIEF DESCRIPTION OF THE DRAWINGS

The two gears 17 are meshed and connected. One end of one of the rotating rods A401 is connected to an external motor. By starting the motor, the rotating rod can be driven to rotate. 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 off more effectively during the cutting action. The crushing knives A402 is set to be elliptical, which can not only increase the crushing contact area, but also make the crushing knife A402 more evenly distribute the crushing force under the same crushing pressure, so that the crushing of the packaging bag residue is smoother, and the rupture or deformation of the packaging bag caused by excessive local force is reduced. A crushing component B5 for crushing the strip-shaped trimming residue is installed at the bottom of the upper collecting shell 2. The crushing component A4 is located in the crushing component B5.

The motor drives the rotating rod B501 to rotate, thereby driving the crushing knife B502 to rotate. The crushing knife B502, the spiral crushing knife B502, can continuously crush the strip-shaped residual material during rotation.

One end of the screw rod 19 is fixedly connected with a limiting plate 20. The threaded connection between the screw rod 19 and the connecting piece 18 is in close contact. When the sealing member 161 abuts against the limiting plate 20, it stops moving. By rotating the screw rod 19, the position of the limiting plate 20 can be adjusted, thereby changing the maximum stroke of the sealing member 161. The outer surface of the fixed cylinder 12 is connected with an air inlet pipe 13 and an air outlet pipe 14. One end of the air outlet pipe 14 is connected with a screw rod 19. The end is connected with an injection assembly 15 for cleaning the crushing assembly A4, and the injection assembly 15 includes a long cylinder 151 and a plurality of nozzles 152.

The long cylinder 151 is connected with the nozzles 152, and the outlet pipe 14 is connected with the long cylinder 151. By connecting the outlet pipe 14 with the long cylinder 151, the gas in the outlet pipe 14 can enter the long cylinder 151 and the plurality of nozzles 152 in turn, so that the nozzles 152 can spray gas, which is beneficial to the cleaning work. The number of fixed cylinders 12 and injection assemblies 15 is set to two, and the interior of the fixed cylinder 12 is installed with a sealing mechanism 16 for sealing the inlet pipe 13 and the outlet pipe 14.

[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 bag to the upper end of the upper collecting box, and the trimming residual materials enter the middle part of the collecting box from the upper end of the collecting box, and two sets of crushing knives A402 are set in the middle part of the collecting 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, and 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 meshed 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 a pair 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 knives 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 knife A402 to be elliptical, the elliptical crushing knife A402 can provide a larger contact area when contacting the packaging bag during the crushing process, compared with traditional straight or other shaped crushing knives. This means that under the same crushing pressure, the elliptical crushing knife A402 can distribute the crushing force more evenly, making the crushing of the packaging bag smoother and reducing the rupture or deformation of the packaging bag caused by excessive local force. The elliptical shape allows the crushing knife A402 to form a continuously changing crushing angle when cutting. During the crushing process, the packaging bags in different parts can be appropriately adjusted to the most suitable crushing angle according to their thickness and material, thereby improving the crushing efficiency and quality. For example, for the thicker part of the packaging bag, the crushing knife can cut in at a larger angle, while for the thinner part, 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 knife A402 needs to be set to be relatively smooth, which can reduce the friction and resistance between the packaging bag and the crushing process. Compared with the sharp straight The elliptical crushing knife A402 is more labor-saving when crushing, which can reduce the energy consumption of the equipment, and also reduce the wear of the crushing knife A402 and extend its service life. It should be noted that the elliptical shape of the crushing knife A402 has certain advantages in structure. It can better withstand the stress and impact force in the crushing process. Compared with crushing knives of other shapes, the elliptical crushing knife has higher strength and rigidity, and is not easy to deform or damage. This is especially important for long-term high-intensity crushing operations. It can ensure the stability and reliability of the crushing knife, reduce the maintenance cost of the equipment, and facilitate installation and fixation; elliptical crushing knives 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 knife A402 and improve the assembly accuracy and production efficiency of the equipment. At the same time, the fixation of the elliptical crushing knife A402 is also more secure, and it is not easy to loosen or shift during the work process, which ensures the accuracy and stability of the crushing. The crushing knife A402 finally crushes the residue into strips.

[0037] Then, the strip-shaped residue enters the bottom of the upper collection box, that is, the area of ​​the crushing knife B502, and 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 several times during the process of rotating one circle, and realize 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 work.

[0038] It should be noted that the trimming residues are usually large blocks with a certain length, width and height before crushing. After crushing, the residues are broken into smaller particles. The total volume of these small particles is significantly smaller than the original block residues. The crushed residue particles can achieve tighter stacking due to their smaller size, and the gaps between the particles are reduced, so that the overall occupied space is reduced. Under the action of gravity, small particles will automatically fill the gaps between large particles to form a tighter stacking structure. This tight stacking method can greatly improve space utilization. For example, in a construction site, sand can be stacked more tightly after crushing, reducing the space required for stacking. The crushed residue particles usually have a certain degree of compressibility. When subjected to external pressure, the gaps between the particles can be further reduced, thereby further reducing the volume of the residue. For example, in the process of garbage disposal, the crushed garbage can be compressed by compression equipment to reduce the occupied space. However, due to the large volume and relatively poor compressibility of the uncrushed residues, it is difficult to achieve effective compression.

[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, several arc plates 22 in the rotating mechanism 7 start to rotate, and the crushed residue is thrown out, so that the residue fits the elastic air bag and accumulates on the outside of the arc plate 22. As the residue increases, the arc plate 22 accumulates the residue. When the thickness of the accumulation is greater than the distance between the arc plate 22 and the elastic air bag, the arc plate 22 will squeeze the residue so that the residue can be tightly compacted, thereby improving the space utilization rate. As the thickness of the accumulation increases, these accumulated residues will squeeze the arc plate 22 to rotate around the rotating shaft 8. At this time, the area of ​​the region composed of multiple arc plates 22 is reduced, providing more space for the residue, and ensuring that the arc 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 blade A402 and the crushing blade 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, so that the piston 162 moves, and the spring 163 starts 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, and the two are opened. The air pump inputs gas, and the gas passes through the air inlet pipe 13, the fixed tube 12, the air outlet pipe 14, the long tube 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 surfaces. 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 arc plate 22 and the residue on the elastic airbag is greater, so the degree of separation of the sealing member 161 from the air inlet pipe 13 and the air outlet pipe 14 is greater, so that the exhaust volume is increased, thereby improving the cleaning effect. Finally, when it is necessary to discharge from the residue, it is only necessary to disassemble the chassis 702.
