The main component is aluminum, and the purity is usually high, generally above 99%. High-purity aluminum can provide good flexibility, ductility and barrier properties. In order to improve its performance, a small amount of alloy elements such as magnesium and manganese are sometimes added. For example, adding magnesium can improve the strength of aluminum foil to a certain extent while maintaining its good processing properties.

[0019] The present invention provides a medical aluminum foil processing technology and cutting equipment. It has the following beneficial effects:

[0020] 1. A medical aluminum foil processing technology and cutting equipment is provided with a winding mechanism, which can make the aluminum foil waste roll more compact and greatly reduce the space it occupies, so that the originally loosely wound aluminum foil waste can be squeezed, and the same mass of waste may only need to occupy half of the original space or even less, so that more waste can be wound and stored on the winding component, and the compacted aluminum foil waste roll is more convenient in the transportation process, whether it is transferred within the workshop or transporting the waste to the recycling and processing point, the transportation space occupied is smaller, which helps to reduce transportation costs, and the compacted waste roll is also more stable in the transportation process, reducing the safety hazards caused by shaking or looseness, and the compacted waste roll can better prevent the waste from scattering during storage and transportation.

[0021] 2. A medical aluminum foil processing technology and cutting equipment is provided with a winding assembly. When the aluminum foil waste on the winding roller is squeezed, the sliding plate can slide on the inner side of the winding roller, so that the pressure of the squeezing roller can be more evenly distributed on the waste. When the squeezing roller applies pressure to the aluminum foil waste roll, the sliding plate will drive the arc plate to move inside the winding roller with the deformation force of the waste, avoiding the situation where the local pressure is too large or too small. Due to the uniform pressure, the compactness of the aluminum foil waste wound on the winding roller is more consistent, which is convenient for subsequent storage, transportation and recycling. The utilization is very beneficial. During storage, waste rolls with uniform compactness are more stable and are not prone to shape changes or damage due to local looseness. The sliding plate can be flexibly adjusted according to the actual amount and characteristics of the aluminum foil waste on the winding roller. When the amount of waste is small, the sliding plate can drive the arc plate to slide by the tensile force of the first spring to adapt to the volume of the smaller waste aluminum foil roll, and the extrusion roller can still effectively extrude the waste aluminum foil roll; when the thickness, hardness and other characteristics of the waste change, the sliding plate can also adjust its position accordingly to ensure the smooth progress of the extrusion work.

[0022] 3. The medical aluminum foil processing technology and cutting equipment are provided with a contact mechanism. When the conveyor belt is conveying and unloading the cut aluminum foil, the conveyor belt is rotating and contacting and rotating with the scraper through the side of the conveyor belt, so that in the process of conveying the medical aluminum foil by the conveyor belt, the side of the conveyor belt is contaminated with dust, aluminum chips and other impurities. The scraper can scrape off the harder granular impurities, such as aluminum chips, which may be generated in the aluminum foil processing process, such as the scraps generated during cutting. The rubber sheet can effectively clean the dust and soft dirt attached to the side, because the rubber has a certain elasticity. The contact frame can better fit the shape of the side of the conveyor belt and wipe off the dirt, thereby improving the cleanliness of the side of the conveyor belt. The scraper and rubber plate can remove these harmful impurities in time, reduce the damage to the conveyor belt, and thus extend the service life of the conveyor belt. At the same time, when the extrusion force between the impurities stuck on the conveyor belt and the scraper is greater than the tensile force of the second spring, the scraper moves downward through the contact frame, and at the same time, the connecting shaft is squeezed through the contact frame, so that the second spring can buffer the extrusion force between the scraper and the conveyor belt to avoid excessive extrusion damage to the side of the conveyor belt.

[0023] 4. A medical aluminum foil processing technology and cutting equipment is provided with an extrusion mechanism. When the cutting work is completed, the suction machine is turned off, and the movable frame is stretched by the reset of the third spring, and the movable frame is driven to move upward by the movable rod, so that the extrusion shaft drives the extrusion shaft to reset and move upward through the movable shaft, so that the extrusion shaft can eject the aluminum material fragments blocked in the mesh of the mesh plate. At the same time, when the third spring is continuously stretched and reset, the movable shaft drives the large and small circular plates on the movable rod to move upward in the mesh of the mesh plate. In the process of medical aluminum foil processing, the sizes of impurities blocked in the mesh of the mesh plate may be different. A large and small circular plate is arranged on the top of the extrusion rod to better cope with this situation. The larger circular plate can be used to eject larger impurities. When encountering larger blocky aluminum chips, plastic particles and other blockages, it can provide a larger contact area and more effectively push them out of the mesh. The smaller circular plate is suitable for clearing smaller meshes or removing smaller impurities, such as dust aggregates, to ensure that the mesh can be cleaned finely.

As a result, the originally loosely wound aluminum foil waste may only need to occupy half or even less space after squeezing, so that more waste can be wound and stored on the winding assembly 293. The compact aluminum foil waste roll is more convenient in transportation, whether it is transferred within the workshop or transporting the waste to the recycling point, and the transportation space it occupies is smaller, which helps to reduce transportation costs. The compact waste roll is also more stable in transportation, reducing the safety hazards caused by shaking or looseness.

[0052] The squeezing mechanism 58 includes a squeezing rod 581, the bottom of the squeezing rod 581 is fixedly connected to the top of the moving frame 55, a moving groove 582 is opened on the side of the squeezing rod 581, a moving block 583 is slidably connected to the inner side of the moving groove 582, a moving shaft 584 is fixedly connected to the side of the moving block 583, the side of the moving shaft 584 is slidably connected to the inner side of the squeezing rod 581, and the side of the moving shaft 584 is fixedly connected to two circular plates 585, the two circular plates 585 are one large and one small, and a squeezing shaft 586 is fixedly connected to the top of the moving shaft 584, and the side of the squeezing shaft 586 is fixedly connected to the inner side of the small circular plate 585. A fourth spring 587 is sleeved on 584, and the top of the fourth spring 587 is fixedly connected to the bottom of the large circular plate 585, and the bottom of the fourth spring 587 is fixedly connected to the top of the extrusion rod 581; when the cutting work is completed, by closing the suction machine 53, the movable frame 55 is stretched by the reset of the third spring 57, and the movable frame 55 is driven by the movable rod 56 to move upward, so that the extrusion shaft 586 is driven by the moving shaft 584 to reset and move upward, so that the extrusion shaft 586 can eject the aluminum material fragments blocked in the mesh of the mesh plate 52, and at the same time, when the third spring 57 is continuously stretched, the movable frame 55 is moved upward by the movable rod 56. The resetting movement enables the moving shaft 584 to drive the large and small circular plates 585 on the moving rod 56 to move upward in the mesh holes of the mesh plate 52. During the processing of medical aluminum foil, the impurities that clog the mesh holes of the mesh plate 52 may vary in size. The large and small circular plates 585 are arranged on the top of the extrusion rod 581 to better cope with this situation. The larger circular plate 585 can be used to eject larger impurities. When encountering larger blocky aluminum chips, plastic particles and other blockages, it can provide a larger contact area and more effectively push them out of the mesh holes. The smaller circular plate 585 is suitable for clearing smaller mesh holes or removing smaller Impurities, such as dust aggregates, etc., ensure that the mesh can be cleaned finely, and at the same time, when the impurities are tightly squeezed against the inner wall of the mesh of the mesh plate 52, the squeezing force between the circular plate 585 and the impurities is greater than the tensile force of the fourth spring 587, so that the moving block 583 slides downward in the moving groove 582, so that the moving block 583 drives the circular plate 585 to move downward through the moving shaft 584, thereby avoiding excessive squeezing force between the circular plate 585 and the inner wall of the mesh of the mesh plate 52, thereby causing excessive friction squeezing force between the impurities and the inner wall of the mesh of the mesh plate 52, which will cause squeezing wear on the inner wall of the mesh of the mesh plate 52;

[0053] Specific workflow:

[0054] The annealed aluminum foil is cut by the cutting component 2, and the cut aluminum foil falls on the conveying component 4 for conveying and unloading. At the same time, the aluminum foil scraps generated during the aluminum foil cutting work can be collected by the collecting component 5;

[0055] The aluminum foil roll is placed on the unloading mechanism 26, one end of the aluminum foil roll is passed through the guide mechanism 25 and placed on the winding mechanism 29, the winding mechanism 29 is turned on, and the hydraulic cylinder 23 is turned on at the same time, and the output end of the hydraulic cylinder 23 drives the movable plate 24 to move downward, so that the movable plate 24 drives the upper die block 27 and the lower die block 28 to extrude, and a shearing effect occurs while pressurizing, and a blank of a required shape and size is cut from the lower die block 28, so that the aluminum foil is cut, and the cut aluminum foil roll is rolled and collected by the winding mechanism 29;

[0056] By turning on the first motor 292, the winding assembly 293 is driven to rotate continuously on the winding frame 291 through the output end of the first motor 292, so that the winding assembly 293 continuously rewinds the aluminum foil waste roll. When the aluminum foil waste rolled on the winding assembly 293 is large, the aluminum foil roll wound on the winding assembly 293 is contacted and rotated with the squeezing roller 295, thereby squeezing the aluminum foil roll on the winding assembly 293, so that the aluminum foil waste roll can be made more compact, greatly reducing its occupied space, thereby making the originally loosely wound aluminum foil waste roll more compact. After extrusion, the same mass of waste may only need to occupy half or even less space than before, so that more waste can be wound and stored on the winding assembly 293. The compact waste aluminum foil roll is more convenient in transportation, whether it is transferred within the workshop or transported to the recycling point, it occupies less transportation space, which helps to reduce transportation costs. The compact waste roll is also more stable in transportation, reducing safety hazards caused by shaking or looseness. The compact waste roll can better prevent the waste from scattering during storage and transportation.

[0057] The output end of the first motor 292 drives the winding roller 2931 to rotate on the winding frame 291. When the cut aluminum foil waste roll is wound up, the aluminum foil waste wound on the winding roller 2931 is squeezed by the squeezing roller 295 at the same time, so that the arc plate 2933 is subjected to the squeezing force, so that the arc plate 2933 drives the sliding plate 2936 to slide on the inner side of the winding roller 2931 through the sliding rod 2932, so that when the aluminum foil waste on the winding roller 2931 is squeezed, the sliding plate 2936 can slide on the inner side of the winding roller 2931, so that the pressure of the squeezing roller 295 can be more evenly distributed on the waste. When the squeezing roller 295 applies pressure to the aluminum foil waste roll, the sliding plate 2936 will drive the arc plate 2933 to move on the inner side of the winding roller 2931 along with the deformation force of the waste. , avoiding the situation where the local pressure is too large or too small. Due to the uniform pressure, the compactness of the aluminum foil waste wound on the winding roller 2931 is more consistent, which is very beneficial for subsequent storage, transportation and recycling. During storage, the waste roll with uniform compactness is more stable and is not prone to shape change or damage due to local looseness. The sliding plate 2936 can be flexibly adjusted according to the actual amount and characteristics of the aluminum foil waste on the winding roller 2931. When the amount of waste is small, the sliding plate 2936 can drive the arc plate 2933 to slide by the tensile force of the first spring 2935 to adapt to the volume of the smaller waste aluminum foil roll, and the squeezing roller 295 can still effectively squeeze the waste aluminum foil roll; when the thickness, hardness and other characteristics of the waste change, the sliding plate 2936 can also adjust its position accordingly to ensure the smooth progress of the squeezing work;

[0058] When the aluminum foil cut by the upper die blade block 27 on the lower die blade block 28 falls onto the conveyor belt 43, the second motor 45 is turned on, and the output end of the second motor 45 drives the active roller 41 to rotate, and the power is transmitted between it and the conveyor belt through friction. The conveyor belt 43 is annular and wrapped around a part of the surface of the active roller 41. The driven roller 42 mainly supports the conveyor belt 43 and changes the movement direction of the conveyor belt 43. On a long-distance conveyor belt 43, there will be multiple driven rollers 42 distributed under the conveyor belt 43, which can ensure The conveyor belt 43 is ensured to maintain proper tension during operation to prevent the conveyor belt 43 from loosening or sagging. At the same time, blanking holes 44 are evenly opened on the side of the conveyor belt 43, so that when the conveyor belt 43 is conveying the cut aluminum foil, impurities attached to the cut aluminum foil can enter the collection box 51 through the blanking holes 44 for collection. At the same time, a contact mechanism 46 is provided under the conveyor belt 43, so that when the conveyor belt 43 is conveying and unloading, the contact mechanism 46 can clean the side of the conveyor belt 43;

[0059] When the conveyor belt 43 is conveying and unloading the cut aluminum foil, the conveyor belt 43 rotates and contacts with the scraper 469 through the side of the conveyor belt 43, so that in the process of conveying the medical aluminum foil by the conveyor belt 43, the side of the conveyor belt 43 is contaminated with dust, aluminum chips and other impurities. The scraper 469 can scrape off harder granular impurities, such as aluminum chips, which may be generated during the processing of the aluminum foil, such as scraps generated during cutting. The rubber plate 468 can effectively clean the dust and soft dirt attached to the side, because the rubber has a certain elasticity and can better fit the shape of the side of the conveyor belt 43 to wipe the dirt dry. The scraper 469 and the rubber plate 468 can remove these harmful impurities in time, reduce the damage to the conveyor belt 43, and extend the service life of the conveyor belt 43. At the same time, when the extrusion force between the impurities stuck on the conveyor belt 43 and the scraper 469 is greater than the tensile force of the second spring 466, the scraper 469 moves downward through the contact frame 467, and at the same time, the contact frame 467 squeezes the connecting shaft 464, so that the second spring 466 buffers the extrusion force between the scraper 469 and the conveyor belt 43, thereby preventing the extrusion damage to the side of the conveyor belt 43 caused by excessive pressure.

[0060] When cutting the aluminum foil, the vacuum machine 53 is turned on, so that the scraps and fragments generated during the cutting are sucked into the collection box 51 through the mesh plate 52 by the suction force of the vacuum machine 53, and then fall on the baffle plate 54 for collection. At the same time, the suction force generated by the vacuum machine 53 causes the moving frame 55 to drive the squeezing mechanism 58 to move downward through the moving rod 56, and at the same time, the third spring 57 is stretched, so that the squeezing mechanism 58 is separated from the mesh of the mesh plate 52, so that the aluminum material fragments generated during the cutting of the aluminum foil can be collected;

[0061] When the cutting work is completed, by closing the suction machine 53, the movable frame 55 is stretched by the reset of the third spring 57, and the movable frame 55 is driven to move upward by the movable rod 56, so that the extrusion shaft 586 drives the extrusion shaft 586 to reset upward through the movable shaft 584, so that the extrusion shaft 586 can eject the aluminum material fragments blocked in the mesh of the mesh plate 52. At the same time, when the third spring 57 is continuously stretched and reset, the movable shaft 584 drives the large and small circular plates 585 on the movable rod 56 to move upward in the mesh of the mesh plate 52. In the processing of medical aluminum foil, the impurities blocking the mesh of the mesh plate 52 may be of different sizes. Arranging a large and a small circular plate 585 on the top of the extrusion rod 581 can better cope with this situation. The larger circular plate 585 can be used to eject larger impurities. When encountering larger blockages such as aluminum chips, plastic particles, etc., it can provide a larger contact area and push them out of the mesh more effectively. The smaller circular plate 585 is suitable for clearing smaller meshes or removing smaller impurities, such as dust aggregates, to ensure that the mesh can be cleaned finely. At the same time, when the impurities are tightly squeezed against the inner wall of the mesh of the mesh plate 52, the squeezing force between the circular plate 585 and the impurities is greater than the tensile force of the fourth spring 587, so that the moving block 583 slides downward in the moving groove 582, so that the moving block 583 drives the circular plate 585 to move downward through the moving shaft 584, thereby avoiding excessive squeezing force between the circular plate 585 and the inner wall of the mesh of the mesh plate 52, thereby causing excessive friction squeezing force between the impurities and the inner wall of the mesh of the mesh plate 52, which will cause squeezing wear on the inner wall of the mesh of the mesh plate 52.
