[0018] The beneficial effects of the present invention, a web-aligning, embossing, and rewinding machine for aluminum foil production, are as follows:

[0019] 1. This invention fundamentally solves the problem of aluminum foil paper damage during correction by replacing the traditional guide roller deflection with lateral displacement correction of the unwinding drum; combined with the mechanical vibration absorption design of the water bladder-C-frame, it effectively suppresses edge vibration and compensates for system deflection errors. The two work synergistically to significantly improve the stability of aluminum foil production and product qualification rate, and are especially suitable for high-speed embossing and rewinding of ultra-thin, high-ductility aluminum foil.

[0020] 2. This invention features a correction mechanism that uses a lead screw and motor to drive the unwinding drum to move laterally as a whole, rather than deflecting the guide rollers. The correction process consists of two steps: First, the unwinding drum moves in the same direction as the aluminum foil deformation to release material stress; second, it moves in the opposite direction to the target position to achieve non-destructive repositioning.

[0021] 3. The present invention is equipped with a vibration absorption component. A C-shaped frame-water bladder structure is set at the edge of the aluminum foil at the floating roller. The fluid characteristics of the water bladder buffer transient impacts, reduce the transmission of tension fluctuations, and the fluidity of the water bladder offsets the angular deviation between the C-shaped frame and the aluminum foil when the floating roller moves.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Please see Figures 1-8 Specifically, the following embodiments are included:

[0040] Example 1:

[0041] A web-aligning, embossing, and rewinding machine for aluminum foil production includes a support base 1, a fixed structure constructed from steel plates and steel pipes, used for ground support and mounting of related mechanical mechanisms. At both ends of the support base are an unwinding drum 2 and a winding drum 3 for winding aluminum foil 4. Both the unwinding drum 2 and the winding drum 3 utilize air-expansion shafts. The winding drum 3 is the primary drive, with a variable frequency motor actively rotating to pull the material forward. A PLC precisely controls the traction force by adjusting the speed / torque of the variable frequency motor to maintain stable tension. The unwinding drum 2 is the driven mechanism, with its connected variable frequency motor configured as a generator. The kinetic energy released by the material is converted into electrical energy, fed back to the power grid or consumed by a resistor, generating a controllable resistance torque. The magnitude of the resistance is adjusted by the PLC based on tension feedback.

[0042] It should be noted that the roll diameter increases during rewinding. If a constant tension is maintained, the outer layer material will squeeze the inner layer, causing "chrysanthemum pattern," deformation of the inner layer material, or even crushing. Therefore, the PLC can dynamically reduce the rewinding tension according to a preset tension attenuation curve by using an encoder or ultrasonic ranging based on the real-time detected rewinding diameter.

[0043] Furthermore, a sensor unit 8 is provided, which includes a transmissive photoelectric sensor. This transmissive photoelectric sensor comprises a transmitter and a receiver, respectively installed on both sides of the aluminum foil 4's running path. The transmitter and receiver must be strictly coaxially aligned, with the light beam perpendicular to the material plane. The transmitter emits a parallel light beam, typically red or infrared light. The receiver detects the beam intensity. When the material edge partially blocks the beam, the light intensity received by the receiver decreases. The receiver outputs a real-time analog voltage signal whose intensity change is proportional to the width of the blockage, i.e., the edge position. The EPC controller reads the actual voltage signal from the sensor. Based on the magnitude and direction of the deviation, the controller calculates the control quantity to be applied to the correction actuator. Specifically, a common correction method involves a servo motor driving a correction guide roller frame to rotate a small angle around its fulcrum. When the material passes through this deflected guide roller, its direction of travel shifts laterally by ΔX. The guide roller length, installation distance, and deflection angle θ are geometrically proportional. The controller controls the deflection direction of the guide roller according to the deviation direction, so that the material edge moves towards the reference position. However, this method has many uncontrollable parameters, and the generated data is inaccurate, resulting in inaccurate movement of the material edge towards the reference position. More importantly, the deviation trajectory can be roughly understood as wavy. When the offset is large, it is difficult to straighten it when the guide roller is deflected. Furthermore, given the poor tensile strength and easy breakage of aluminum foil, this method is difficult to achieve deviation correction.

[0044] Therefore, this invention proposes a correction method. Specifically, instead of the traditional method of generating lateral displacement by deflecting guide rollers, it directly moves the unwinding drum 2 laterally to adjust the material edge towards the reference position. Based on the data fed back by the transmission photoelectric sensor, the offset is calculated. First, the unwinding drum 2 is moved along the offset direction, that is, along the direction of aluminum foil deformation, so as not to tear the aluminum foil. Then, it is moved in the opposite direction of the offset direction to achieve correction, ensuring that the aluminum foil 4 is not damaged after resetting.

[0045] Specifically, the structure used to perform the above operations includes, for example, the unwinding drum 2 is slidably connected to the support base 1 via a correction mechanism 5. The correction mechanism 5 drives the aluminum foil 4 on the unwinding drum 2 to move to correct the conveying direction of the aluminum foil 4. Multiple sets of guide rollers 10 are arranged between the unwinding drum 2 and the take-up drum 3. The correction mechanism 5 includes a motor 50, which is fixed to the support base 1. The output end of the motor 50 is coaxially fixed to the lead screw 51. A guide block 52 is threaded onto the lead screw 51. The guide block 52 is fixed to the connecting plate 53. The unwinding drum 2 is arranged on the connecting plate 53. The connecting plate 53 is slidably connected to the support base 1.

[0046] During operation, the motor drives the lead screw 51 to rotate, thereby causing the guide block 52 to move laterally, which in turn causes the unwinding drum 2 located on the connecting plate 53 to move laterally. Based on the data fed back by the sensor and the magnitude of the displacement, the unwinding drum 2 moves laterally at least twice to correct the deviation. That is, the unwinding drum 2 can move laterally back and forth to ensure that damage to the aluminum foil is reduced.

[0047] The right side of the correction mechanism 5 consists of, in order, a clamping assembly 6, a tension adjustment assembly 7, a sensor unit 8, and a printing unit 9. Of course, the clamping assembly 6 is a movable structure and needs to be placed before the printing unit 9.

[0048] like Figure 7 As shown, specifically, the clamping assembly 6 includes a cylinder 61, which is fixed on a support frame 60. The support frame 60 is fixed to the connecting plate 53. The output end of the cylinder 61 is fixed to a pressure plate 62. An aluminum foil 4 is provided between the pressure plate 62 and the clamping rod 63. The clamping rod 63 is fixed to the support frame 60.

[0049] Before correction, it is necessary to ensure that the aluminum foil 4 before printing is in the reference position. Therefore, the aluminum foil 4 needs to be clamped to avoid printing misalignment. The support frame 60 is a detachable structure and can be installed at any position before the printing unit 9.

[0050] It should be noted that floating rollers are commonly used to control tension in this field. This invention also includes a tension adjustment component 7, specifically a floating roller 70. The floating roller 70 is a freely rotating guide roller, usually covered with rubber or silicone to increase friction. The floating roller 70 is slidably connected to the support base 1 and can move up and down. Guide rollers 10 are provided on both sides of the floating roller 70 to jointly support the aluminum foil 4. The force balancing device, position sensor, and other structures provided on the floating roller 70 are conventional means in this field and will not be described in detail here. What needs to be explained is the working principle of the floating roller 70, namely, tension change → floating roller displacement → sensor signal → PLC calculation → actuator adjustment → tension recovery. The advantage of the floating roller is that it directly reflects the actual tension of the material, is not directly affected by factors such as motor characteristics, transmission efficiency, and material slippage, has high precision, and has a buffering effect. The movement of the floating roller can absorb transient tension fluctuations such as material impact and slight speed changes, providing smoother tension control, but it also has a buffering effect to a certain extent. Therefore, this invention provides a structure that can absorb the edge vibration of the aluminum foil 4 and reduce transient tension fluctuations.

[0051] Specifically, a vibration absorption component 71 is provided on the edge of the aluminum foil 4 on the floating roller 70. The vibration absorption component 71 includes a rectangular C-shaped frame 72 with a through C-shaped hole 73 inside. Through holes 74 are provided on the three outer inner walls of the C-shaped frame 72. The through holes 74 are opened along the length of the C-shaped frame 72, and the length of the through holes 74 is less than half the length of the C-shaped frame 72. A water bladder 75 protrudes from the through holes 74. The water bladder 75 is fixed inside the mounting box 76, which has a frame structure on its sides. Specifically, as shown... Figure 6 As shown, the mounting box 76 is half a frame and half a closed structure. The water bladder 75 leaks out from the frame of the mounting box 76. The water bladder 75 is connected to a water supply pipe 77. The surface of the water bladder 75 that is in contact with the aluminum foil 4 is coated with an oil film. The water volume of the water bladder 75 is less than its volume, that is, the water bladder 75 is not filled completely, so that the part that leaks out in the through hole 74 has extensibility. The C-shaped frame 72 of the present invention "holds" the edge of the aluminum foil 4, so that it can better absorb the transient fluctuations of the edge of the aluminum foil 4, reduce displacement, thereby reducing the difficulty of correction and increasing the controllability of tension.

[0052] It should be noted that the floating roller 70 and the aluminum foil 4 on it are dynamic, therefore the C-shaped frame 72 needs to be driven by it. Specifically, the C-shaped frame 72 is fixed to the first rotating shaft 78, the first rotating shaft 78 is connected to the first fixed plate 707 by a bearing, the first fixed plate 707 is fixed to the support structure on the floating roller 70, the floating roller 70 is rotatably connected to the support mechanism, and the support mechanism is slidably connected to the support base 1. A damping component 701 is also fixed on the first rotating shaft 78 to prevent the C-shaped frame 72 from rotating. The damping component 701 includes a notch. Ring 702, the notched ring 702 is fixedly connected to the first rotating shaft 78, the notched ring 702 is rotatably connected to the outer ring 703, the outer ring 703 is fixedly connected to the first fixing plate 707 through an auxiliary rod 706, a stop block 704 is provided at the notch of the notched ring 702, the stop block 704 is fixed to the outer ring 703, the stop block 704 is fixed to one end of the first spring 705, the first spring 705 is fixed to one end of the notched ring 702, and the other end of the notched ring 702 intermittently overlaps with the stop block 704.

[0053] When the floating roller 70 moves longitudinally, the C-shaped frame 72 needs to follow suit. In this invention, the first rotating shaft 78, fixed to the C-shaped frame 72, moves longitudinally with the floating roller 70. It should be noted that when the floating roller 70 moves longitudinally, it causes the aluminum foil 4 to deflect at an angle. Therefore, the C-shaped frame 72 needs to follow this deflection. This invention employs a damping component 701, and the notched ring 702 can rotate along the outer ring 703, preventing the C-shaped frame 72 from rotating due to its own weight when stationary. The notched ring 702 is connected to a first spring 705, and the traction force of the first spring 705 makes it difficult for the notched ring 702 to rotate. This invention achieves the following deflection through the above mechanical mechanism. The deflection accuracy needs to take into account the weight of the notched ring 702, the elastic coefficient of the first spring 705, and the corresponding friction. Those skilled in the art can determine the relevant technical indicators through experiments. Alternatively, an angle offset sensor can be used to detect the deflection angle and then control the rotation of the C-shaped frame 72. However, although the use of a sensor will improve the accuracy, it requires the detection of parameters and the operation of the PLC, which involves complicated calculations and is not as practical as a mechanical mechanism. Moreover, in order to reduce rotation error, this invention cleverly designs a water bladder 75. The fluid characteristics of the water bladder 75 will reduce the deviation between the rotation of the aluminum foil 4 and the rotation of the C-shaped frame 72. Therefore, the water bladder 75 can absorb transient fluctuations and reduce rotation deviation.

[0054] The water bladder 75 can be replaced with an air bladder.

[0055] For further explanation of this example, refer to Figure 1 and Figure 8The printing unit 9 includes two printing rollers 90, which are idler rollers without power. Their speed is driven by the friction of the material and passively follows the main speed. The two printing rollers 90 are arranged on the upper and lower sides of the aluminum foil 4. The lower printing roller 90 is connected to the fixed frame 91 by a bearing, and the upper printing roller 90 is arranged in a long frame 92 and moves and rotates along it. The long frame 92 is opened on the fixed frame 91. The end of the printing roller 90 is fixed to the guide rod 93. The guide rod 93 moves along the guide hole opened in the inner wall of the long frame 92. A second spring 94 is fitted on the guide rod 93. The second spring 94 presses the printing roller 90 onto the aluminum foil 4 to ensure the consistency of the embossing quality.

[0056] The two sets of elongated frames 92, guide rods 93, and second springs 94 are symmetrically arranged about the center of the printing rollers 90. Printing is produced on the aluminum foil 4 by the rotation of the two printing rollers 90. A drying device should also be used in conjunction with the printing process.

[0057] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
