[0031] Figures 1 to 4 The automatic roll changing device for aluminum foil unwinding equipment shown includes a fixed plate 1. A motor 4 is provided on one side of the fixed plate 1. A rotating rod 5 is provided at the output end of the motor 4. A first placement plate 6 is provided on one side of the rotating rod 5. Several electric telescopic rods 7 are provided on one side of the first placement plate 6. A second placement plate 8 is fixedly connected to one side of the rotating rod 5. A round rod 9 is provided on the side of the second placement plate 8 near the electric telescopic rods 7. A protective device 2 is provided on one side of the fixed plate 1 to shield and protect the motor 4. During automatic roll changing, the fixing plate 1 is fixed to other equipment. The electric telescopic rod 7 at the top of the first placement plate 6 is activated, so that the output end of the electric telescopic rod 7 cooperates with the round rod 9 on the second placement plate 8 to clamp the roller at the bottom of the hopper. Then, the motor 4 on the fixing plate 1 is activated, so that the rotating rod 5 drives the first placement plate 6 and the second placement plate 8 to rotate. At this time, the motor 4 is protected by the protective device 2. Then the clamped roller rotates, and the roller at the bottom of the hopper disengages from the hopper. The remaining rollers at the top of the hopper fall automatically under gravity, so that there is always one roller at the bottom of the hopper. After the roller rotates to a suitable angle, the aluminum foil is unwound. After the aluminum foil is unwound to a certain extent, the above operation is repeated to perform automatic roll changing.
[0032] Figures 1 to 4 The protective device 2 shown includes a slide rail 21, which is fixedly connected to a fixed plate 1. A sliding block 22 is slidably connected to one side of the slide rail 21. An extension plate 23 is fixedly connected to one side of the sliding block 22. A locking block 24 is inserted into one side of the extension plate 23. A locking groove 25 is opened on one side of the slide rail 21. The locking block 24 engages with the locking groove 25 on one side of the slide rail 21. A protective plate 26 is fixedly connected to one side of the sliding block 22. A control frame 27 is fixedly connected to one side of the protective plate 26. When using motor 4, the protective plate 26 can be moved via control frame 27, causing the protective plate 26 to slide inside the slide rail 21 along the sliding block 22, thus shielding and protecting motor 4. Then, the locking block 24 is moved so that it passes through extension plate 23 and engages with the locking groove 25 on one side of slide rail 21, thus fixing the position of the protective plate 26. By using the protective device 2, motor 4 can be shielded and protected when in use, preventing motor 4 from being exposed and thus easily damaged by force, which could affect the service life of motor 4, thereby improving the performance of the automatic roll changing device.
[0033] Figures 1 to 4 The sliding block 22 shown has arc-shaped strips 28 fixedly connected to both sides, with the arc surfaces of the arc-shaped strips 28 close to the slide rail 21. The use of the arc-shaped strips 28 reduces the friction between the sliding block 22 and the slide rail 21, making it easier for the sliding block 22 to move within the slide rail 21. A reinforcing plate 29 is fixedly connected inside the slide rail 21, and the reinforcing plate 29 is slidably connected to the sliding block 22. The use of the reinforcing plate 29 increases the connection strength between the slide rail 21 and the sliding block 22, preventing separation of the sliding block 22 from the slide rail 21. A rubber sleeve 210 is fixedly connected to one side of the control frame 27, and the size of the rubber sleeve 210 is adapted to the size of the control frame 27. The use of the rubber sleeve 210 increases the friction between the control frame 27 and the operator, making it easier for the operator to move the control frame 27. Several heat dissipation holes 211 are fixedly connected to both sides of the protective plate 26, and the heat dissipation holes 211 are arranged at equal intervals on both sides of the protective plate 26. By using the heat dissipation holes 211, the protective plate 26 can be ventilated, and the protective plate 26 does not affect the heat dissipation of the motor 4, thereby improving the performance of the protective plate 26.
[0034] Figures 1 to 4The extension plate 23 shown has a limiting component 3 on one side. The limiting component 3 includes a square plate 31, one side of which is fixedly connected to the extension plate 23. A baffle 32 is inserted inside the square plate 31, and the size of the baffle 32 is adapted to the size of the locking block 24. When using the locking block 24, the baffle 32 inside the square plate 31 can be moved to restrict the position of the locking block 24, thus blocking and restricting its position. By using the limiting component 3, the position of the locking block 24 can be blocked and limited, preventing the locking block 24 from disengaging from the slot 25 on one side of the slide rail 21, thereby improving the usability of the locking block 24.
[0035] Figures 1 to 4 A magnet 33 is fixedly connected to one side of the square plate 31, and an iron sheet 34 is fixedly connected to one side of the baffle 32. The magnet 33 on the square plate 31 attracts the iron sheet 34 on the baffle 32, making the baffle 32 less prone to movement under force, thereby improving the effectiveness of the baffle 32.
[0036] Working principle: During automatic roll changing, the fixed plate 1 is fixed to other equipment. The electric telescopic rod 7 at the top of the first placement plate 6 is activated, so that the output end of the electric telescopic rod 7 cooperates with the round rod 9 on the second placement plate 8 to clamp the roller at the bottom of the hopper. Then, the motor 4 on the fixed plate 1 is activated, so that the rotating rod 5 drives the first placement plate 6 and the second placement plate 8 to rotate. At this time, the motor 4 is protected by the protective device 2. Then the clamped roller rotates. At this time, the roller at the bottom of the hopper is disengaged from the hopper, and the remaining rollers at the top of the hopper fall automatically under gravity, so that there is always one roller at the bottom of the hopper. After the roller rotates to a suitable angle, the aluminum foil is unwound. After the aluminum foil is unwound to a certain extent, the above operation is repeated to automatically change the roll. When using motor 4, the protective plate 26 can be moved via control frame 27, causing the protective plate 26 to slide inside the slide rail 21 along the sliding block 22, thus shielding and protecting motor 4. Then, the locking block 24 is moved so that it passes through extension plate 23 and engages with the locking groove 25 on one side of slide rail 21, thus fixing the position of the protective plate 26. By using the protective device 2, motor 4 can be shielded and protected when in use, preventing motor 4 from being exposed and thus easily damaged by force, which could affect the service life of motor 4, thereby improving the performance of the automatic roll changing device.
[0037] When using the card block 24, the baffle 32 inside the square plate 31 can be moved to restrict the position of the card block 24. At this time, the iron piece 34 on the baffle 32 can be attracted by the magnet 33 on the square plate 31. By using the limiting component 3, the position of the card block 24 can be blocked and limited, so that the card block 24 cannot be dislodged from the card slot 25 on one side of the slide rail 21, thereby improving the use effect of the card block 24.
[0038] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model.
