Description
Technical Field
[0001] This utility model relates to the technical field of aluminum foil processing equipment, and in particular to an aluminum foil winding device with anti-fall function. Background Technology
[0002] Aluminum foil is a common metallic material widely used in packaging, electronics, and industrial fields due to its excellent ductility, moisture resistance, and light-shielding properties. During the continuous rolling and winding process of aluminum foil, when localized thickness unevenness, microscopic defects, or tension fluctuations occur, the aluminum foil may break under the influence of winding tension. Even after breakage, the production line continues to operate, causing the broken foil to sag rapidly under its own weight due to the loss of tension, forming a hanging section. This hanging section may not only trigger secondary fractures at the break point but may also cause friction or collisions between the foil and equipment components, resulting in physical damage such as scratches or wrinkles on the foil surface. These damages significantly reduce the mechanical properties and appearance quality of the aluminum foil, thus decreasing the yield of finished aluminum foil. Utility Model Content
[0003] In view of this, it is necessary to provide an aluminum foil winding device with anti-fall function, which can effectively suppress the formation of excessive overhang segments after the aluminum foil breaks, thereby reducing the damage to the aluminum foil and improving the yield of aluminum foil.
[0004] This utility model provides an aluminum foil winding device with anti-fall function, including a winding component, an anti-fall component, and a triggering component. The winding component is used to tighten and wind up the aluminum foil. The anti-fall component includes a driving component and a lifting component. The fixed end of the driving component is disposed at the feed end of the winding component. The lifting component is installed at the output end of the driving component and is located below the aluminum foil. It is used to lift the broken aluminum foil and descend synchronously with the falling aluminum foil under the drive of the driving component. The detection end of the triggering component faces the running path of the aluminum foil and is electrically connected to the driving component so as to activate the driving component when the aluminum foil breaks, thereby driving the lifting component to descend.
[0005] Preferably, the drive assembly includes a first frame, a second frame, a lifting drive motor, a lead screw, a slide rod, a lifting component, and a sliding component. The first frame and the second frame are symmetrically arranged on both sides of the aluminum foil. A lifting groove is formed along the vertical direction of the first frame. The fixed end of the lifting drive motor is installed at the bottom of the lifting groove. One end of the lead screw is driven and connected to the output end of the lifting drive motor, and the other end is rotatably connected to the top of the lifting groove. The lifting component is threadedly connected to the lead screw so that the lifting component moves up and down along the lead screw under the drive of the lifting drive motor. A sliding groove is formed along the vertical direction of the second frame. The two ends of the slide rod are fixedly connected to the top and bottom of the sliding groove, respectively. The sliding component is slidably installed on the slide rod.
[0006] Preferably, the lifting assembly includes an arc-shaped anti-fall plate, with the lower end of the anti-fall plate fixedly connected to the lifting member and the sliding member on both sides, so as to be lifted and lowered under the drive of the driving assembly.
[0007] Preferably, the lifting assembly further includes two support frames, a first clamping roller, a second clamping roller, and two lifting groups. The two support frames are symmetrically arranged on both sides of the higher end of the anti-fall plate. The two ends of the first clamping roller are rotatably mounted on the two support frames and are lower than the running path of the aluminum foil. The second clamping roller is arranged above the first clamping roller and is higher than the running path of the aluminum foil. The fixed ends of the two lifting groups are respectively installed on the top of the two support frames, and their telescopic ends extend downward and are rotatably connected to the two ends of the second clamping roller, so that the height of the second clamping roller can be adjusted by the synchronous lifting of the two lifting groups. Then, after the aluminum foil breaks, the height of the second clamping roller is lowered by the lifting groups, so that the first clamping roller and the second clamping roller clamp the broken aluminum foil.
[0008] Preferably, each lifting assembly includes a lifting motor and a lifting rod. The fixed end of the lifting motor is fixedly installed on the top of the corresponding support frame. The lifting rod is vertically arranged and driven to the output end of the lifting motor. The bottom of the lifting rod is provided with an installation ring. The installation ring is rotatably connected to one end of the second clamping roller so as to drive the lifting rod to lift and lower through the lifting motor, thereby controlling the lifting and lowering of the second clamping roller.
[0009] Preferably, the lifting assembly further includes a clamping roller drive motor, the fixed end of which is mounted on one of the support frames, and its driving end is connected to the first clamping roller drive to drive the first clamping roller to rotate.
[0010] Preferably, the triggering component includes two foil breakage detection sensors and a signal receiver. The two foil breakage detection sensors are respectively mounted on the first frame and the second frame, and are set at the same height with their detection ends facing the running path of the aluminum foil, so as to monitor the state of the aluminum foil in real time and send a foil breakage signal to the signal receiver when the aluminum foil breaks. The signal receiver is electrically connected to the two foil breakage detection sensors, the lifting drive motor, the lifting motor, and the clamping roller drive motor, and is used to start the lifting drive motor, the lifting motor, and the clamping roller drive motor after receiving the foil breakage signal from the foil breakage detection sensors.
[0011] Preferably, the triggering component further includes an audible and visual alarm, which is mounted on the top surface of the second frame and electrically connected to the signal receiver to issue an audible and visual alarm when the signal receiver receives a foil breakage signal.
[0012] Preferably, the winding component includes a winding frame and a winding roller, with aluminum foil wound around the winding roller; both ends of the winding roller are rotatably connected to the top surface of the winding frame, and one end of the winding roller is driven by an external drive device, so that the winding roller rotates under the drive of the external drive device, thereby tightening and winding the aluminum foil.
[0013] Preferably, the winding component includes two locking assemblies, which are respectively disposed on both sides of the top surface of the winding machine frame. Each locking assembly includes a fixed support and a rotating clamp. The fixed support is fixedly installed on the top surface of the winding machine frame, and the first end of the rotating clamp is rotatably installed on the first end of the fixed support. The second end of the fixed support has a first locking hole, and the second end of the rotating clamp has a second locking hole. Both the first and second locking holes are threaded to lock the second ends of the fixed support and the rotating clamp together with fastening bolts. The rotating clamp has an arc-shaped groove for engaging one end of the winding roller to achieve a rotatable connection between the winding roller and the winding machine frame.
[0014] The aforementioned aluminum foil winding device with anti-fall function includes a winding component, an anti-fall component, and a triggering component. The winding component is used to tighten and wind up the aluminum foil. The anti-fall component includes a drive assembly and a lifting assembly. The fixed end of the drive assembly is located at the feed end of the winding component. The lifting assembly is installed at the output end of the drive assembly and is located below the aluminum foil. It is used to lift the broken aluminum foil and descends synchronously with the falling aluminum foil under the drive of the drive assembly. The detection end of the triggering component faces the running path of the aluminum foil and is electrically connected to the drive assembly so that the drive assembly is activated when the aluminum foil breaks, thereby driving the lifting assembly to descend. Thus, when the aluminum foil breaks, the broken aluminum foil falls... The aluminum foil is then placed on the lifting assembly to prevent it from falling further. Simultaneously, a triggering component detects a break in the aluminum foil, activating the drive assembly. Driven by the drive assembly, the lifting assembly descends synchronously with the falling aluminum foil. This is because the production line continues to operate, with aluminum foil constantly being produced and falling from upstream. If the lifting assembly remained stationary, the aluminum foil above the lifting point would accumulate and form a hanging section before eventually falling. Therefore, the lifting assembly needs to descend synchronously with the falling aluminum foil to continuously catch newly generated aluminum foil, effectively suppressing the formation of excessively large hanging sections after the aluminum foil breaks, thereby reducing damage to the aluminum foil and improving the yield of finished aluminum foil.

Detailed Implementation
[0023] The technical solutions and effects of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.
[0024] Please refer to Figure 1This utility model provides an aluminum foil winding device 10 with anti-fall function, including a winding component 20, an anti-fall component 30, and a triggering component 40. The winding component 20 is used to tighten and wind up the aluminum foil. The anti-fall component 30 includes a drive assembly 31 and a lifting assembly 32. The fixed end of the drive assembly 31 is located at the feed end of the winding component 20. The lifting assembly 32 is installed at the output end of the drive assembly 31 and is located below the aluminum foil. It is used to lift the broken aluminum foil and descends synchronously with the falling aluminum foil under the drive of the drive assembly 31. The detection end of the triggering component 40 faces the running path of the aluminum foil and is electrically connected to the drive assembly 31 so that the drive assembly 31 is activated when the aluminum foil breaks, thereby driving the lifting assembly 32 to descend. When the aluminum foil breaks, the broken aluminum foil falls onto the lifting component 32, which prevents the aluminum foil from falling further. At the same time, the trigger component 40 detects the breakage of the aluminum foil and activates the drive component 31. Driven by the drive component 31, the lifting component 32 descends synchronously with the falling aluminum foil. This is because the production line is still running, and aluminum foil will continue to be produced from upstream and fall. If the lifting component 32 remains stationary, the aluminum foil above the lifting point will accumulate and form a hanging section again before eventually falling. Therefore, the lifting component 32 needs to descend synchronously with the falling aluminum foil to continuously receive the newly generated aluminum foil, effectively suppressing the formation of excessively large hanging sections after the aluminum foil breaks, thereby reducing the damage to the aluminum foil and improving the yield of aluminum foil.
[0025] Please refer to Figure 2 and Figure 3 Furthermore, the drive assembly 31 includes a first frame 311, a second frame 312, a lifting drive motor 313, a lead screw 314, a slide bar 315, a lifting component 316, and a sliding component 317. The first frame 311 and the second frame 312 are symmetrically arranged on both sides of the aluminum foil. A lifting groove 318 is opened along the vertical direction of the first frame 311. The fixed end of the lifting drive motor 313 is installed at the bottom of the lifting groove 318. One end of the lead screw 314 is driven and connected to the output end of the lifting drive motor 313, and the other end is rotatably connected to the top of the lifting groove 318. The lifting component 316 is threadedly connected to the lead screw 314 so that the lifting component 316 moves up and down along the lead screw 314 under the drive of the lifting drive motor 313. A sliding groove 319 is opened along the vertical direction of the second frame 312. The two ends of the slide bar 315 are fixedly connected to the top and bottom of the sliding groove 319, respectively. The sliding component 317 is slidably installed on the slide bar 315.
[0026] Please refer to Figures 2 to 5Furthermore, the lifting assembly 32 includes an arc-shaped anti-fall plate 321. The two sides of the lower end of the anti-fall plate 321 are fixedly connected to the lifting member 316 and the sliding member 317 respectively, so as to lift and lower under the drive of the drive assembly 31. Specifically, the arc-shaped anti-fall plate 321 allows the falling aluminum foil to land smoothly on the plate, avoiding secondary scratches or folds on the edge of the plate. The lower end of the anti-fall plate 321 is fixed to the drive assembly 31, while the higher end faces the running path of the aluminum foil, forming an angle of attack, which more effectively receives and guides the aluminum foil.
[0027] In this embodiment, the descent speed of the fall arrestor 321 is consistent with the linear speed of the aluminum foil production line. The specific value is derived from the material and thickness of the aluminum foil and the adjustment of the production line operating parameters. Based on this value, the operating power of the lifting drive motor 313 is manually adjusted to ensure that the fall arrestor 321 can synchronously receive the aluminum foil continuously produced from upstream and avoid accumulation to form a hanging section.
[0028] Please refer to Figure 4 and Figure 5 Furthermore, the lifting assembly 32 also includes two support frames 322, a first clamping roller 323, a second clamping roller 324, and two lifting groups 325. The two support frames 322 are symmetrically arranged on both sides of the higher end of the fall arrestor plate 321. The two ends of the first clamping roller 323 are rotatably mounted on the two support frames 322 and are lower than the running path of the aluminum foil. The fixed ends of the two lifting groups 325 are respectively mounted on the top of the two support frames 322, and their telescopic ends extend downward and are rotatably connected to the two ends of the second clamping roller 324, so that the two lifting groups 325 can be lifted simultaneously. The height of the second clamping roller 324 is adjusted by the lifting mechanism 325. After the aluminum foil breaks, the height of the second clamping roller 324 is lowered by the lifting mechanism 325, so that the first clamping roller 323 and the second clamping roller 324 can clamp the broken aluminum foil. Specifically, when the aluminum foil is not broken, the second clamping roller 324 is raised to a high position by the lifting mechanism 325 to leave an unobstructed passage for the aluminum foil. When the breakage occurs, the lifting mechanism 325 causes the second clamping roller 324 to descend rapidly, cooperate with the first clamping roller 323 in a fixed position, and clamp the broken aluminum foil to prevent the aluminum foil from falling from the higher end of the anti-fall plate 321.
[0029] Please refer to Figure 5Furthermore, each lifting assembly 325 includes a lifting motor 3251 and a lifting rod 3252. The fixed end of the lifting motor 3251 is fixedly installed on the top of the corresponding support frame 322. The lifting rod 3252 is vertically arranged and driven by the output end of the lifting motor 3251. The bottom of the lifting rod 3252 is provided with a mounting ring 3253. The mounting ring 3253 is rotatably connected to one end of the second clamping roller 324 so that the lifting rod 3252 can be driven to rise and fall by the lifting motor 3251. This controls the lifting and lowering of the second clamping roller 324. Specifically, after receiving a trigger signal, the lifting motor 3251 drives the lifting rod 3252 to descend quickly and precisely, causing the second clamping roller 324 to press against the aluminum foil already located on the first clamping roller 323, forming a clamping force. The synchronous action of the two lifting groups 325 ensures that both ends of the second clamping roller 324 are pressed down synchronously, avoiding aluminum foil deviation or local stress concentration caused by asynchrony, thereby stably clamping the broken aluminum foil and preventing it from slipping off the high end of the anti-fall plate 321.
[0030] In one embodiment, the lifting motor 3251 is a high-precision servo motor, and the lifting rod 3252 is the push rod of the servo electric cylinder. The servo motor can precisely control the displacement and speed of the lifting rod 3252 through the controller, so as to realize the fast, smooth and precise lifting action of the second clamping roller 324.
[0031] Please refer to Figure 4 Furthermore, the lifting assembly 32 also includes a clamping roller drive motor 326. The fixed end of the clamping roller drive motor 326 is mounted on one of the support frames 322, and its driving end is drivenly connected to the first clamping roller 323 to drive the first clamping roller 323 to rotate. Specifically, when the aluminum foil is clamped by the first clamping roller 323 and the second clamping roller 324, the clamping roller drive motor 326 starts and drives the first clamping roller 323 to rotate, so as to pull the aluminum foil to move towards the fall arrestor 321, thereby preventing the aluminum foil from excessively accumulating at the higher end of the fall arrestor 321 and forming a new overhang.
[0032] Please refer to Figure 2 and Figure 3 Furthermore, the triggering component 40 includes two foil breakage detection sensors 41 and a signal receiver. The two foil breakage detection sensors 41 are respectively mounted on the first frame 311 and the second frame 312. The two foil breakage detection sensors 41 are set at the same height, and the detection ends are both facing the running path of the aluminum foil, so as to monitor the state of the aluminum foil in real time and send a foil breakage signal to the signal receiver when the aluminum foil breaks. The signal receiver is electrically connected to the two foil breakage detection sensors 41, the lifting drive motor 313, the lifting motor 3251, and the clamping roller drive motor 326, and is used to start the lifting drive motor 313, the lifting motor 3251, and the clamping roller drive motor 326 after receiving the foil breakage signal from the foil breakage detection sensor 41.
[0033] In this embodiment, the foil breakage detection sensor 41 is a through-beam photoelectric sensor. Specifically, the two photoelectric sensors are a light source emitter and a light signal receiver, respectively, which are precisely positioned on opposite sides of the aluminum foil's running path. The horizontal detection beam emitted by the light source emitter passes under the normally running aluminum foil and is stably received by the light signal receiver. When the aluminum foil is running normally, the detection beam is unobstructed. When the aluminum foil breaks, the broken aluminum foil falls rapidly under its own weight. During the fall, it obstructs the detection beam, causing a sudden change in the state of the light signal received by the light signal receiver. This sudden change signal is immediately sent to the signal receiver as a foil breakage signal.
[0034] In this embodiment, the signal receiver uses a relay logic circuit, such as a combination of an intermediate relay and a time relay. When the foil breakage detection sensor 41 outputs a foil breakage signal, the relay circuit is directly turned on, driving the lifting drive motor 313, the lifting motor 3251, and the clamping roller drive motor 326 to start. No software intervention is required; signal transmission and equipment control are achieved solely through hardware circuitry.
[0035] Please refer to Figure 2 and Figure 3 Furthermore, the triggering component 40 also includes an audible and visual alarm 42, which is installed on the top surface of the second frame 312 and electrically connected to the signal receiver to issue an audible and visual alarm when the signal receiver receives a broken foil signal. Specifically, the audible and visual alarm issued by the audible and visual alarm 42 can promptly notify the operator to handle the broken aluminum foil, so that the operator can handle the broken aluminum foil in a timely manner. At the same time, by continuously supporting the newly generated aluminum foil by the lifting component, sufficient reaction time can be provided for the operator to ensure that the broken aluminum foil can be handled in a timely manner and avoid interruption of aluminum foil production.
[0036] Please refer to Figure 6 Furthermore, the winding component 20 includes a winding frame 21 and a winding roller 22, with the aluminum foil wound around the winding roller 22. Both ends of the winding roller 22 are rotatably connected to the top surface of the winding frame 21, and one end of the winding roller 22 is driven by an external drive device, so that the winding roller 22 rotates under the drive of the external drive device, thereby tightening and winding the aluminum foil. Specifically, the external drive device is usually a servo motor or a frequency converter motor, which is directly connected to the shaft end of the winding roller 22 through a transmission mechanism such as a coupling or gearbox, providing the winding roller 22 with stable and precisely controllable rotational torque and speed. This connection method ensures that the aluminum foil can maintain constant tension during the winding process, thereby winding into a tight and neat roll.
[0037] In this embodiment, both the take-up roller 22 and the first clamping roller 323 are driven rollers so that the take-up roller 22 can rotate under the drive of an external drive device, thereby providing a stable take-up tension for the aluminum foil; the first clamping roller 323 rotates under the drive of the clamping roller drive motor 326, thereby actively pulling the falling aluminum foil after it breaks, preventing it from accumulating on the anti-fall plate 321.
[0038] Please refer to Figure 6 and Figure 7 Furthermore, the winding component 20 includes two locking assemblies 23, which are respectively disposed on both sides of the top surface of the winding frame 21. Each locking assembly 23 includes a fixed support 231 and a rotating clamp 232. The fixed support 231 is fixedly installed on the top surface of the winding frame 21, and the first end of the rotating clamp 232 is rotatably installed on the first end of the fixed support 231. The second end of the fixed support 231 has a first locking hole, and the second end of the rotating clamp 232 has a second locking hole. Both the first and second locking holes are threaded to lock the second ends of the fixed support 231 and the rotating clamp 232 together with fastening bolts. The rotating clamp 232 has an arc-shaped slot 233 for locking one end of the receiving roll 22, so as to realize the rotational connection between the taking-up roll 22 and the taking-up frame 21. Specifically, the structure of the locking component 23 also realizes the detachable connection between the taking-up roll 22 and the taking-up frame 21. When a roll of aluminum foil is finished, the operator only needs to loosen the fastening bolts on the locking component 23, open the rotating clamp 232, and lift the fully loaded taking-up roll 22 off the taking-up frame 21. Then, an empty roll is installed, and the clamp is locked to start the next roll winding. This design saves roll changing time, improves production efficiency, and also facilitates the individual maintenance and upkeep of the taking-up roll 22.
[0039] Example 1: Working process of aluminum foil winding device 10 with anti-fall function
[0040] 1. Driven by an external drive device, the aluminum foil is continuously pulled past the anti-fall component 30 and finally tightened and wound up by the winding roller 22 of the winding component 20. During this process, the two foil breakage detection sensors 41 of the trigger component 40 continuously emit detection beams to monitor the continuous state of the aluminum foil in real time. At this time, the lifting component 32 of the anti-fall component 30 is in the standby position, that is, the arc-shaped anti-fall plate 321 is located at a predetermined distance below the aluminum foil running path; at the same time, the second clamping roller 324 maintains a large distance from the first clamping roller 323 to ensure that the aluminum foil can pass smoothly between the first clamping roller 323 and the second clamping roller 324.
[0041] 2. When the aluminum foil breaks, the downstream part of the break point loses tension and begins to droop under its own weight. During the drooping process, it blocks the detection beams of the two foil breakage detection sensors 41, causing the light signal detected by the foil breakage detection sensors 41 to change abruptly. This abrupt signal is the foil breakage signal, and the foil breakage signal is sent to the signal receiver.
[0042] 3. After receiving the foil breakage signal, the signal receiver performs the following operations simultaneously: the audible and visual alarm 42 issues an audible and visual alarm;
[0043] The lifting drive motor 313 starts, drives the lead screw 314 to rotate, and drives the lifting component 316, which is threadedly connected to the lead screw 314, to move downward along the lifting groove 318, so that the anti-fall plate 321 descends synchronously.
[0044] The lifting motor 3251 drives the lifting rod 3252 to move downward, which in turn causes the second clamping roller 324 to descend rapidly and work together with the first clamping roller 323 to clamp the broken aluminum foil that has fallen onto the anti-fall plate 321.
[0045] The clamping roller drive motor starts, driving the second clamping roller 324 to rotate, pulling the clamped aluminum foil to move towards the lower end of the fall arrestor plate 321;
[0046] 4. After receiving the audible and visual alarm, the operator shall handle the broken aluminum foil, for example, by rewinding the broken aluminum foil onto the take-up roller 22. After the handling is completed, the components of the aluminum foil take-up device 10 with anti-fall function shall be reset to restore the normal production of aluminum foil.
[0047] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
