[0032] Reference Figure 1-3 As shown, an online buffer device for continuous dual aluminum strip extrusion includes: a device frame 5 and a first aluminum strip unwinding device 1, a second aluminum strip unwinding device 2, a first aluminum strip tensioning structure 3, and a second aluminum strip tensioning structure 4, all mounted on the device frame. A feeding unit 51 and a discharging unit 52 are respectively arranged on both sides of the device frame 5. The feeding unit 51 includes a first aluminum strip inlet and a second aluminum strip inlet. The discharging unit 52 includes a first aluminum strip outlet and a second aluminum strip outlet. The first aluminum strip coil is installed on the first aluminum strip unwinding device 1 for unwinding. The first aluminum strip passes through the first aluminum strip inlet, through the first aluminum strip tensioning structure 3, and to the first aluminum strip outlet. The second aluminum strip coil is installed on the second aluminum strip unwinding device 2. The second aluminum strip passes through the second aluminum strip inlet, through the second aluminum strip tensioning structure 4, and to the second aluminum strip outlet. This device has a simple structure and is equipped with two unwinding devices and tensioning mechanisms, providing two aluminum strips with tension for the extrusion production line, improving production efficiency while ensuring the quality of the card strip production.
[0033] It is worth noting that the first aluminum strip unwinding device 1 is also divided into a first aluminum strip unwinding in-use unit 11 and a first aluminum strip unwinding waiting unit 12. A rotating disk 13 is provided at the lower end of the first aluminum strip unwinding device 1. The rotating disk 13 is connected to a base 14. The base 14 is installed on the equipment frame 5. Therefore, the first aluminum strip unwinding device 1 can rotate horizontally, which is convenient for workers to operate and install the first aluminum strip. After the aluminum strip roll in the first aluminum strip unwinding in-use unit 11 is used up, the new first aluminum strip in the first aluminum strip unwinding waiting unit 12 can be rotated to the in-use side, which shortens the time for the first aluminum strip to be replaced by the new one, greatly reduces the workload of workers, avoids waste and occupation of working space, and avoids the aluminum strip being scattered, knotted, and easily cut.
[0034] The first aluminum strip tensioning structure 3 includes: a first upper aluminum strip tensioning wheel group 31, a first lower aluminum strip tensioning wheel group 32, a set of first aluminum strip tension adjustment structures, and a set of first tension servo motors 33. The first tension servo motors 33 drive the first upper aluminum strip tensioning wheel group 31 and the first lower aluminum strip tensioning wheel group 32. Both the first upper aluminum strip tensioning wheel group 31 and the first lower aluminum strip tensioning wheel group 32 are composed of multiple independent tensioning wheels. The first tension servo motors 33 drive and control the first aluminum strip tension adjustment structures to adjust the position of the tension wheels to adjust the tension of the first aluminum strip. The second aluminum strip tensioning structure 4 includes: a second upper aluminum strip tensioning wheel group 41, a second lower aluminum strip tensioning wheel group 42, a set of second tension adjustment structures, a set of second tension servo motors 43, and a first feed servo motor 511. Two tensioning servo motors 43 drive the upper tensioning roller group 41 and the lower tensioning roller group 42 of the second aluminum belt. Both the upper tensioning roller group 41 and the lower tensioning roller group 42 of the second aluminum belt are composed of multiple independent tensioning rollers. The second tensioning servo motor 43 drives and controls the second aluminum belt tensioning adjustment mechanism to adjust the position of the tension rollers to adjust the tension of the second aluminum belt. The second aluminum belt tensioning structure 4 is also equipped with a first feeding servo motor 511. After the second aluminum belt passes through the upper and lower tensioning roller groups, it passes through the second aluminum belt inlet, ensuring that the second aluminum belt and the first aluminum belt maintain the same feeding speed.
[0035] Preferably, the feeding unit 51 and the discharging unit 52 are respectively equipped with a first feeding servo motor and a discharging servo motor. A speed sensor is installed on the discharging unit 52. The speed sensor synchronizes the aluminum strip discharging speed to the equipment control system. The control system matches the corresponding control signals and sends them to the first feeding servo motor 511, the second feeding servo motor 44, the discharging servo motor 521, the first tensioning servo motor 33, and the second tensioning servo motor 43 to adjust the position of the tensioning wheel on the first aluminum strip tensioning adjustment structure and the second aluminum strip tensioning adjustment structure. This equipment matches the speed of the card strip production line and can continuously and safely provide the card strip production line with tensioned aluminum strip. Compared with the prior art, this utility model equipment has the beneficial effects of saving space and reducing the workload of workers, and is worthy of further market promotion.
[0036] Example 1: A dual-aluminum strip continuous extrusion online buffer device is a pre-processing aluminum strip device for automotive windshield strip production lines. See [link to example]. Figure 2 The image shown is a top view of the equipment. In actual production, the equipment is mainly divided into two parts, left and right. The left part is equipped with a first aluminum strip unwinding device 1. The first aluminum strip is relatively large. The first aluminum strip unwinding device 1 is divided into a first aluminum strip unwinding in-use unit 11 and a first aluminum strip unwinding waiting unit 12. A rotating disk 13 is set at the lower end of the first aluminum strip unwinding device 1. Therefore, when the first aluminum strip is used up, the first aluminum strip unwinding device 1 can be rotated horizontally, which is convenient for workers to operate and install the first aluminum strip. On the right side, a tensioning wheel assembly is set in the middle, and the upper space is a space for buffering the first aluminum strip. The first aluminum strip is buffered in the tensioning wheel assembly, so that when the first aluminum strip needs to be replaced, the first aluminum strip will not stop being output, ensuring continuous production of the strip production line. The lower part is equipped with an unwinding device for installing the second aluminum strip. It can be seen that the second aluminum strip is smaller in size, so the unwinding device is also relatively small.
[0037] In specific implementation, firstly, the first aluminum strip coil is installed on the first aluminum strip unwinding device 1 for unwinding. After the first aluminum strip enters through the first aluminum strip inlet, the first aluminum strip enters and is serpentinely wound around the first upper tensioning roller group 31 and the first lower tensioning roller group 32. At this time, the first aluminum strip has tension and exits from the first aluminum strip output port of the discharge unit 52. The second aluminum strip coil is installed on the second aluminum strip unwinding device 2. The second feeding servo motor 44 drives the second aluminum strip into the second aluminum strip upper tensioning roller group 41 and the second aluminum strip lower tensioning roller 42. The second tensioning servo motor 43 drives and controls the second aluminum strip tensioning adjustment mechanism to adjust the position of the tension wheel to adjust the tension of the second aluminum strip. The second aluminum strip with tension exits from the second aluminum strip output port of the discharge unit 52. The discharge servo motor 521 ensures that the second aluminum strip and the first aluminum strip maintain the same output speed. The two aluminum strips enter the automotive windshield strip production line at the same speed but with different tensions.
[0038] Under normal conditions, the upper and lower tensioning rollers tension and store the first aluminum strip. When the aluminum strip on the side of the unwound unit 11 is about to run out, the worker presses the pressure roller button. The first feeding servo motor 511 on the feeding unit stops rotating, and the pressure roller clamps the end of the first aluminum strip. The worker can then open the rotating disk fixing structure and press the rotation button for the first aluminum strip unwound device to rotate it horizontally. This horizontally rotates and exchanges the positions of the first aluminum strip unwound waiting unit 12 and the first aluminum strip unwound in use unit 11, welding the end of the almost-run-out first aluminum strip to the beginning of the newly opened first aluminum strip. At this time, the first aluminum strip tensioning structure 3 does not stop operating. During the time that the end of the first aluminum strip is clamped and welded by the pressure roller, the first aluminum strip buffered by the first tensioning structure can continue to be output from the first aluminum strip outlet of the output unit. The second aluminum strip tensioning structure 4 also does not stop operating. The second aluminum strip buffered in the second tensioning structure continues to be output from the second aluminum strip outlet of the output unit. When the second aluminum strip needs to be replaced, the aluminum strip output will not stop, thus ensuring continuous production of the card strip. This equipment requires only one worker to operate, which effectively reduces the difficulty and workload for workers, thereby reducing costs and increasing efficiency.
[0039] In summary, the online buffer device for continuous extrusion of dual aluminum strips provided in this application has a simple and reasonable structure, is easy to operate, and improves the existing technical problems of single aluminum strip buffer devices. During welding, the aluminum strips do not need to be scattered and stacked, allowing for operation by a single person. Furthermore, the output speed of the aluminum strips is kept matched with the extrusion line speed, and the aluminum strips maintain tension during welding, making breakage less likely. This device is suitable for widespread use in the market. Of course, the application scenarios of this utility model are not limited to pre-processing in automotive windshield strip production lines; it can also be applied to the pre-processing of strip materials in other product manufacturing processes, which will not be elaborated upon here. In addition, the structure of this device can be modified according to application scenarios and environments to adapt to various production needs, and the scope of protection of the modified technical solutions all fall within the scope of protection of this utility model.
[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
