Description

Technical Field

[0001] This invention relates to the field of aluminum foil recycling technology, specifically to a core stripping device and stripping method for recycling aluminum foil roll waste. Background Technology

[0002] During the production, processing, and use of aluminum foil rolls, as well as in the finishing and slitting stages and even in returns from downstream customers, a portion of waste aluminum foil is generated. This waste material is usually wound onto paper cores to form rolls. To achieve resource recycling, the aluminum foil needs to be peeled off from the paper cores, and then the aluminum foil rolls without the paper cores are packaged as waste for recycling.

[0003] Currently, when recycling waste aluminum foil rolls with a diameter of 300-500mm and a paper core diameter of 10-15mm from downstream customers, traditional manual methods or simple mechanical cutting methods are commonly used. For example, patents CN103128549A (an automatic cutting and peeling machine for waste aluminum foil rolls) and CN201792191U (a thin roll waste cutting and peeling machine) both separate the rolls from the core by cutting them open. These two methods have the following problems: First, manually cutting the aluminum foil with a hand-held knife to remove the paper core is labor-intensive, inefficient, and poses serious safety hazards. Second, while mechanical cutting with a cutting machine improves efficiency to some extent, the cutting machine surface accumulates a large amount of aluminum powder during the cutting process. Both manual and mechanical cutting generate a large amount of aluminum dust, polluting the working environment, harming the health of operators, and causing aluminum material loss.

[0004] Therefore, the present invention provides a core stripping device and stripping method for recycling aluminum foil roll waste to solve the above problems. Summary of the Invention

[0005] The technical problem to be solved by this invention is to overcome the existing defects and provide a core stripping device and method for recycling aluminum foil roll waste. This method separates the paper core from the aluminum foil roll through mechanical extrusion and winding separation, replacing the traditional cutting and stripping process. This avoids the generation of aluminum dust, improves the working environment, and reduces aluminum material loss. It also avoids the safety hazards of manual cutting, eliminates the risk of workplace injuries that may arise from cutting machines, improves work efficiency, greatly reduces labor intensity, and is simple and convenient to operate, effectively solving the problems in the background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a core stripping device for recycling aluminum foil roll waste, comprising a base, two pressure rollers capable of synchronously moving horizontally in opposite directions are symmetrically arranged on one side of the base, and the peripheral side of the pressure rollers is provided with uniformly distributed protrusions. A pressure plate capable of moving up and down is provided on the upper side of the pressure rollers. A slide rail is mounted on the other side of the base via a bracket. A linear motor is slidably arranged on the slide rail. A fixed frame capable of moving up and down is provided on the linear motor. Two sliders capable of moving horizontally are provided on the fixed frame. A thin roller extending upwards from the pressure rollers is rotatably arranged on the sliders. The annular protrusion of the thin roller is provided with uniformly distributed protrusions.

[0007] As a preferred embodiment of the present invention, the base and the pressure roller are provided with sliding rods at their respective ends. The sliding rods and the pressure roller are slidably provided with mounting seats at their respective ends. The side of the base is provided with a horizontal hydraulic cylinder connected to the middle of the mounting seat. The pressure roller is rotatably mounted on the mounting seat. A reduction motor is provided on one side of the mounting seat, and the output shaft of the reduction motor is connected to one end of the pressure roller through a coupling.

[0008] As a preferred embodiment of the present invention, the base is provided with a support frame on the side corresponding to the pressure roller, and a vertical hydraulic cylinder is provided on the top of the support frame, with the pressure plate installed at the bottom of the vertical hydraulic cylinder.

[0009] As a preferred embodiment of the present invention, both ends of the fixing frame are provided with vertically arranged vertical electric push rods, and the telescopic ends of the vertical electric push rods are installed on the upper surface of the linear motor.

[0010] As a preferred embodiment of the present invention, the fixing frame is provided with an upper sliding rod, the slider is slidably mounted on the upper sliding rod, and the inner side of the fixing frame is provided with a horizontal electric push rod for driving the slider to move, the telescopic end of the horizontal electric push rod being connected to the side of the slider.

[0011] As a preferred embodiment of the present invention, a servo motor is provided on the side of the slider, and a reducer is provided on the output shaft of the servo motor, with one end of the fine roller installed at the output end of the reducer.

[0012] A peeling method for a core peeling device used in aluminum foil roll waste recycling includes the following steps:

[0013] S1. Adjust the initial positions of the pressure roller and the fine roller according to the size of the aluminum foil roll waste of the paper tube core, and in the initial stage, the fine roller is located on the upper side of the pressure roller.

[0014] S11. The adjustment method of the pressure roller is as follows: control the horizontal hydraulic cylinder to work, the horizontal hydraulic cylinder drives the mounting base and the pressure roller to move along the sliding rod, thereby adjusting the distance between the two pressure rollers;

[0015] S12. The adjustment method of the fine roller is as follows: The horizontal electric push rod and the vertical electric push rod work together. The vertical electric push rod drives the fixed frame to move in the vertical direction. The fixed frame drives the slider and the fine roller to move through the upper slide rod, thereby adjusting the height of the fine roller. The horizontal electric push rod pushes the slider and the fine roller to move along the upper slide rod, thereby adjusting the distance between the two fine rollers.

[0016] S2. Place the aluminum foil roll waste of the paper tube core on two pressure rollers, and fit the paper tube core onto two thin rollers;

[0017] S3. Control the servo motor and vertical hydraulic cylinder to work. The servo motor drives the fine roller to rotate through the reducer. The vertical hydraulic cylinder pushes the pressure plate to move down. During the pressing process, the pressure plate squeezes the top of the aluminum foil roll and causes the upper side of the middle of the aluminum foil roll to be concave downward. The contact area between the aluminum foil roll and the pressure roller usually produces a certain degree of concavity. At the same time, the aluminum foil roll causes the top of the paper tube core to be concave downward, so that the inner wall of the paper tube core is captured by the protrusions on the rotating fine roller. Under the action of the fine roller rotation, the upper end of the paper tube core is slowly wound by two fine rollers with protrusions, thereby peeling the paper tube core from the inner wall of the aluminum foil roll.

[0018] S4. Control the linear motor to work. The linear motor drives the fixed frame to move along the slide rail through the vertical electric push rod. It drives the slider and fine roller to move through the upper slide rod. The fine roller drives the paper tube core to move out of the aluminum foil roll.

[0019] S5. Increase the distance between the two pressure rollers according to the adjustment method of the pressure rollers in S11, and control the vertical hydraulic cylinder to extend again. The vertical hydraulic cylinder pushes the aluminum foil roll between the two pressure rollers through the pressure plate. At the same time, control the two reduction motors to work. The two reduction motors drive the corresponding pressure rollers to rotate. Under the cooperation of the pressure plate, the aluminum foil roll stripped from the paper tube core is squeezed into a flattened structure and discharged from the underside of the two pressure rollers.

[0020] S6. After the aluminum foil roll is discharged, control the pressure plate and pressure roller to reset, and control the linear motor to move towards the pressure roller. The linear motor indirectly drives the paper tube core to move to the upper side of the pressure roller. At this time, control the servo motor to rotate in the opposite direction, so that the fine roller with protrusions rotates in the opposite direction, so that the protrusions are disengaged from the paper tube core. Then the paper tube core can be removed from the fine roller.

[0021] As a preferred technical solution of the present invention, in S3, under the action of the pressure roller and the pressure plate, the upper and lower parts of the aluminum foil roll deform towards the middle, and the middle part of the aluminum foil roll deforms towards both sides. Therefore, in S5, after increasing the distance between the two pressure rollers and before the vertical hydraulic cylinder extends, a reduction motor is first controlled to drive the corresponding pressure roller to rotate. The pressure roller drives the aluminum foil roll to rotate and insert it between the two pressure rollers. Then, the operation after the vertical hydraulic cylinder extends in S5 is performed.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. The aluminum foil roll waste recycling tube core stripping device and stripping method of the present invention can support the aluminum foil roll and flatten the aluminum foil roll after removing the paper tube core, which facilitates the recycling of aluminum foil rolls.

[0024] 2. The aluminum foil roll waste recycling tube core peeling device and peeling method of the present invention uses a fine roller with protrusions to roll up the extruded paper tube core, thereby separating the paper tube core from the interior of the aluminum foil roll. At the same time, the horizontally moving fine roller can remove the paper tube core from the aluminum foil roll. The paper tube core is peeled off by using a non-cutting method of roll-up separation, which replaces the traditional cutting peeling method and avoids the generation of aluminum dust.

[0025] 3. The aluminum foil roll waste recycling tube core stripping device and stripping method of the present invention separates the paper tube core from the aluminum foil roll through mechanical extrusion and winding separation without cutting, replacing the traditional cutting and stripping process. This avoids the generation of aluminum dust, improves the working environment, and reduces aluminum material loss. At the same time, it avoids the safety hazards of manual cutting, eliminates the risk of workplace injury that may be caused by cutting machines, and can also improve work efficiency. It is simple to operate and convenient to use. Attached Figure Description

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] Please see Figure 1-7 The present invention provides a technical solution: a core stripping device for recycling aluminum foil roll waste, including a base 1. Two pressure rollers 3 that can move horizontally in opposite directions synchronously are symmetrically arranged on one side of the base 1. The pressure rollers 3 can support the aluminum foil roll and flatten the aluminum foil roll after the paper core has been removed, which facilitates the recycling of the aluminum foil roll. The pressure rollers 3 have evenly distributed protrusions 31 on their peripheral side, which helps to create a gap between the paper core and the inner wall of the roll after the aluminum foil roll is squeezed.

[0036] The upper side of the pressure roller 3 is provided with a pressure plate 42 that can move up and down. The other side of the base 1 is equipped with a slide rail 5 via a bracket. A linear motor 51 is slidably mounted on the slide rail 5. The linear motor 51 is provided with a fixed frame 6 that can move up and down. The fixed frame 6 is provided with two sliders 62 that can move horizontally. A thin roller 7 extending upwards from the pressure roller 3 is rotatably mounted on the sliders 62. The annular protrusion of the thin roller 7 is provided with evenly distributed protrusions 71. During the downward pressing process of the pressure plate 42, the top of the aluminum foil roll is squeezed and the upper middle part of the aluminum foil roll is concave downwards. The aluminum foil roll drives the top of the paper tube core. The paper tube is recessed downwards, allowing the inner wall of the paper core to be captured by the protrusions 71 on the rotating fine roller 7. The fine roller 7 with protrusions 71 winds up the compressed paper core, thereby separating the paper core from the interior of the aluminum foil roll. The linear motor 51 drives the fixed frame 6 to move along the slide rail 5 via the vertical electric push rod 52, and drives the slider 62 and the fine roller 7 to move via the upper slide rod 61. The horizontally moving fine roller 7 can remove the paper core from the aluminum foil roll. The paper core is peeled off by using a non-cutting method of winding and separating, which replaces the traditional cutting and peeling method, thereby avoiding the generation of aluminum dust.

[0037] Furthermore, the base 1 and the pressure roller 3 are each provided with a sliding rod 2 at their respective ends. The sliding rod 2 and the pressure roller 3 are slidably provided with a mounting seat 21 at their respective ends. The side of the base 1 is provided with a horizontal hydraulic cylinder 22 connected to the middle of the mounting seat 21. The pressure roller 3 is rotatably mounted on the mounting seat 21. One side of the mounting seat 21 is provided with a reduction motor 32, and the output shaft of the reduction motor 32 is connected to one end of the pressure roller 3 through a coupling. The two reduction motors 32 drive the corresponding pressure rollers 3 to rotate. Under the cooperation of the pressure plate 42, the aluminum foil roll stripped from the paper tube core is squeezed into a flattened structure and discharged from the underside of the two pressure rollers 3.

[0038] Furthermore, a support frame 4 is provided on the side of the base 1 corresponding to the pressure roller 3, and a vertical hydraulic cylinder 41 is provided on the top of the support frame 4, with the pressure plate 42 installed at the bottom of the vertical hydraulic cylinder 41.

[0039] Furthermore, both ends of the fixed frame 6 are provided with vertically arranged vertical electric push rods 52. The telescopic ends of the vertical electric push rods 52 are mounted on the upper surface of the linear motor 51. The fixed frame 6 is provided with an upper slide rod 61, and the slider 62 is slidably mounted on the upper slide rod 61. The inner side of the fixed frame 6 is provided with a horizontal electric push rod 63 that drives the slider 62 to move. The telescopic end of the horizontal electric push rod 63 is connected to the side of the slider 62. Through the operation of the horizontal electric push rod 63 and the vertical electric push rod 52, the vertical electric push rod 52 drives the fixed frame 6 to move in the vertical direction. The fixed frame 6 drives the slider 62 and the fine roller 7 to move through the upper slide rod 61, thereby adjusting the height of the fine roller 7. The horizontal electric push rod 63 pushes the slider 62 and the fine roller 7 to move along the upper slide rod 61, thereby adjusting the distance between the two fine rollers 7.

[0040] Furthermore, a servo motor 72 is provided on the side of the slider 62, and a reducer 73 is provided on the output shaft of the servo motor 72. One end of the fine roller 7 is installed at the output end of the reducer 73, and the servo motor 72 drives the fine roller 7 to rotate through the reducer 73.

[0041] A peeling method for a core peeling device used in aluminum foil roll waste recycling includes the following steps:

[0042] S1. Adjust the initial positions of pressure roller 3 and fine roller 7 according to the size of the aluminum foil roll waste of paper tube core, and in the initial stage, fine roller 7 is located on the upper side of pressure roller 3.

[0043] S11, the adjustment method of the pressure roller 3 is as follows: control the horizontal hydraulic cylinder 22 to work, the horizontal hydraulic cylinder 22 drives the mounting base 21 and the pressure roller 3 to move along the sliding rod 2, thereby adjusting the distance between the two pressure rollers 3;

[0044] The adjustment method of S12 and the fine roller 7 is as follows: The horizontal electric push rod 63 and the vertical electric push rod 52 work together. The vertical electric push rod 52 drives the fixed frame 6 to move in the vertical direction. The fixed frame 6 drives the slider 62 and the fine roller 7 to move through the upper slide rod 61, thereby adjusting the height of the fine roller 7. The horizontal electric push rod 63 pushes the slider 62 and the fine roller 7 to move along the upper slide rod 61, thereby adjusting the distance between the two fine rollers 7.

[0045] S2. Place the waste aluminum foil roll of paper core onto the two pressure rollers 3, and fit the paper core onto the two fine rollers 7, as shown. Figure 5 and Figure 6 As shown in a;

[0046] S3. Control the servo motor 72 and the vertical hydraulic cylinder 41 to work. The servo motor 72 drives the fine roller 7 to rotate through the reducer 73; the vertical hydraulic cylinder 41 pushes the pressure plate 42 downward. During the downward pressing process, the pressure plate 42 squeezes the top of the aluminum foil roll and causes the upper middle part of the aluminum foil roll to be concave downward. The contact area between the aluminum foil roll and the pressure roller 3 usually produces a certain degree of concavity. At the same time, the aluminum foil roll causes the top of the paper tube core to be concave downward, so that the inner wall of the paper tube core is captured by the protrusions 71 on the rotating fine roller 7. Figure 6 As shown in Figure b, under the rotation of the fine roller 7, the upper end of the paper core is slowly wound up by the two fine rollers 7 with protrusions 71, thereby peeling the paper core from the inner wall of the aluminum foil roll. Figure 6 As shown in c;

[0047] S4. Control the linear motor 51 to work. The linear motor 51 drives the fixed frame 6 to move along the slide rail 5 through the vertical electric push rod 52. It drives the slider 62 and the fine roller 7 to move through the upper slide rod 61. The fine roller 7 drives the paper tube core to move out of the aluminum foil roll.

[0048] S5 Figure 7 Figure a shows a schematic diagram after the paper core is removed from the aluminum foil roll after extrusion. The distance between the two pressure rollers 3 is increased according to the adjustment method of pressure roller 3 in S11, as follows: Figure 7 As shown in b; the vertical hydraulic cylinder 41 is extended again, and the vertical hydraulic cylinder 41 pushes the aluminum foil roll between the two pressure rollers 3 through the pressure plate 42. At the same time, the two reduction motors 32 are controlled to work, and the two reduction motors 32 drive the corresponding pressure rollers 3 to rotate. Under the cooperation of the pressure plate 42, the aluminum foil roll stripped from the paper tube core is squeezed into a flattened structure and discharged from the underside of the two pressure rollers 3, as shown in b. Figure 7 As shown in c;

[0049] S6. After the aluminum foil roll is discharged, control the pressure plate 42 and pressure roller 3 to reset, and control the linear motor 51 to move towards the pressure roller 3. The linear motor 51 indirectly drives the paper tube core to move to the upper side of the pressure roller 3. At this time, control the servo motor 72 to rotate in the opposite direction, so that the fine roller 7 with the protrusions 71 rotates in the opposite direction, so that the protrusions 71 are disengaged from the paper tube core. Then the paper tube core can be removed from the fine roller 7.

[0050] Furthermore, in S3, under the action of the pressure roller 3 and the pressure plate 42, the upper and lower parts of the aluminum foil roll deform towards the middle, and the middle part of the aluminum foil roll deforms towards both sides. Therefore, in S5, after increasing the distance between the two pressure rollers 3 and before the vertical hydraulic cylinder 41 extends, a reduction motor 32 is first controlled to drive the corresponding pressure roller 3 to rotate. The pressure roller 3 drives the aluminum foil roll to rotate and insert it between the two pressure rollers 3. Then, the operation after the vertical hydraulic cylinder 41 extends in S5 is performed.

[0051] The geared motor 32, linear motor 51, vertical electric push rod 52, horizontal electric push rod 63, and servo motor 72 used in this invention are all commonly used electrical devices in the prior art. All electrical devices used in this invention are electrically connected to an external switch group, and the methods of controlling the two electric push rods, two hydraulic cylinders, and two motors are all conventional technical means in the field. Their working methods and circuit structures are well-known technologies and will not be described in detail here.

[0052] This invention separates the paper core from the aluminum foil roll through a non-cutting method of mechanical extrusion and winding separation, replacing the traditional cutting and peeling process. This avoids the generation of aluminum dust, improves the working environment, and reduces aluminum material loss. It also avoids the safety hazards of manual cutting, eliminates the risk of workplace injury that may be caused by cutting machines, improves work efficiency, and is simple and convenient to operate.

Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
