When the base plate 15 is fully inserted into the clearance groove 14, the magnet 23 on the left side of the side plate 16 attracts the iron sheet 22 on the right side of the box 1.

[0024] Those skilled in the art will understand that by pulling the handle 19, the base plate 15 is pulled out of the clearance groove 14 via the casters 20, and the processed aluminum foil shielding paper roll can be placed on the storage rod 18 on the front side of the fixing plate 17; when the base plate 15 is pushed back, the magnet 23 on the left side of the side plate 16 attracts the iron sheet 22 at the open end of the right side of the box 1, thus fixing it. This provides convenient temporary storage space, the casters 20 are designed for easy material transfer, and the attraction between the magnet 23 and the iron sheet 22 enhances stability during storage, preventing the base plate 15 from sliding during device operation.

[0025] Example 3 Furthermore, a protective box 24 is fixedly connected to the rear side of the housing 1.

[0026] Those skilled in the art will understand that the protective box 24 encapsulates the first drive unit 10 and the second drive unit 13, and the first heat dissipation vent 26 and the first filter achieve heat dissipation and dust prevention; by unscrewing the threaded knob 29 on the first connecting block 27 and the second connecting block 28, the inspection box door 25 can be opened to inspect the internal drive components. This design protects the drive units from external dust and impacts, extending their service life. The heat dissipation structure ensures stable operation of the components, and the convenient inspection door design reduces maintenance difficulty.

[0027] Example 4 Furthermore, the locking assembly 3 includes a cavity 301 located at the bottom front side of the housing 1. A matching pressure plate 302 is provided inside the cavity 301. The pressure plate 302 moves longitudinally within the cavity 301. Two vertically arranged first locking rods 303 are fixedly connected to the pressure plate 302.

The bottom ends of the two first locking rods 303 extend to the bottom of the housing 1 and are fixedly connected to a foot pedal 305. A first spring 306 located inside the cavity 301 and below the pressure plate 302 is sleeved on the two first locking rods 303. The upper and lower ends of the first spring 306 are fixedly connected to the bottom of the pressure plate 302 and the bottom of the cavity 301, respectively.

[0028] Those skilled in the art will understand that when the pedal 305 is pressed, the first locking lever 303 drives the pressure plate 302 to compress the first spring 306 inside the cavity 301, disengaging it from the first locking groove 304 of the visible door 2, thus opening the door. Upon releasing the pedal, the first spring 306 returns to its original position, and the first locking lever 303 inserts into the first locking groove 304 to complete the locking. The foot-operated design is simple and effortless, and the spring return ensures reliable locking, facilitating quick opening of the door for internal cleaning, adjustment, or troubleshooting.

[0029] Example 5 Furthermore, the cleaning component 6 includes a square mounting ring 601 fixedly connected to the left side of the housing 1 and located outside the inlet 4.

A pull block 609 is fixedly connected to the outside of the T-shaped inserts 603.

[0030] Those skilled in the art will understand that before the aluminum foil shielding paper enters the inlet 4, the cleaning brush 604 inside the square mounting ring 601 removes surface impurities with soft nylon bristles; pulling the pull plate 607 causes the second locking rod 605 to compress the second spring 608 and disengage from the second locking groove 606 of the T-shaped insert 603, and the T-shaped insert 603 can be pulled out by the pull block 609 to replace the brush plate. Pre-cleaning the material surface impurities improves processing quality, and the cooperation between the T-shaped slot 602 and the T-shaped insert 603 makes the brush plate easy to install and remove, facilitating maintenance and replacement.

[0031] Example 6 Furthermore, the first drive unit 10 includes a first motor 1001 fixedly connected to the rear side of the housing 1. The first motor 1001 is electrically connected to the controller. A first pinion 1002 is fixedly connected to the output end of the first motor 1001, and a first large gear 1003 that meshes with the first pinion 1002 is fixedly connected to the rear end of the rotating shaft.

[0032] Those skilled in the art will understand that when the controller starts the first motor 1001, the first pinion 1002 at its output end meshes with the first large gear 1003 at the rear end of the rotating shaft, driving the rotating shaft to rotate. This, in turn, causes the rotating plate 7, roller shaft 8, and tension roller 9 to rotate synchronously, thereby adjusting the tension of the aluminum foil shielding paper. The gear transmission has high precision and can accurately control the speed of the tension roller 9, adapting to the tension requirements of aluminum foil shielding paper of different thicknesses and materials, ensuring smooth conveying.

[0033] Example 7 Furthermore, the inner support mechanism 12 includes two symmetrically arranged slide grooves 1201 on the rotating rod 11. Two movable rings 1202 are slidably connected to the rotating rod 11. The inner rings of the movable rings 1202 are fixedly connected to two sliders 1203 that are adapted to the two slide grooves 1201. The two sliders 1203 are slidably arranged in the two slide grooves 1201 respectively. A horizontally arranged double-threaded rod 1204 is rotatably connected in the slide groove 1201. The sliders 1203 in the two slide grooves 1201 are symmetrically threaded to the two threads on both sides of the double-threaded rod 1204 in their respective slide grooves 1201. On the segment, the outer rings of the two moving rings 1202 are provided with a number of grooves 1205 arranged in a ring array. Each groove 1205 is hinged with a support rod 1206. The grooves 1205 on the two moving rings 1202 correspond one-to-one with the support rods 1206. The outer ends of the two corresponding support rods 1206 on the two moving rings 1202 are hinged with an arc-shaped support plate 1207. The outer arc surface of the arc-shaped support plate 1207 is provided with a flexible anti-slip pad. The front ends of the two double-headed threaded rods 1204 extend to the front end of the rotating rod 11 and are connected to the third drive unit 1208.

[0034] Those skilled in the art will understand that the two grooves 1201 on the rotating rod 11 are equipped with double-ended threaded rods 1204, and the moving ring 1202 is connected to the double-ended threaded rods 1204 via a slider 1203. When the double-ended threaded rods 1204 rotate, the moving ring 1202 moves symmetrically along the grooves 1201, causing the support rod 1206 in the groove 1205 to push the arc-shaped support plate 1207 to expand or contract, and the flexible anti-slip pad is fixed to the inner wall of the winding drum. It can be adapted to winding drums of different inner diameters, and symmetrical adjustment ensures uniform clamping. The flexible anti-slip pad not only prevents slippage but also protects the drum, improving winding stability.

[0035] Example 8 Furthermore, the third drive unit 1208 includes a mounting groove 1281 located in the middle of the front end of the rotating rod 11.

A second large gear 1283 is fixedly connected to the front output end of the second motor 1282. A second small gear 1284 that meshes with the second large gear 1283 is fixedly connected to the front end of each of the two double-ended threaded rods 1204. The second motor 1282 drives the two double-ended threaded rods 1204 to rotate synchronously through gear transmission, ensuring that the two moving rings 1202 move symmetrically.

[0036] Those skilled in the art will understand that after the second motor 1282 in the mounting slot 1281 at the front end of the rotating rod 11 starts, the second large gear 1283 at its output end meshes with the second small gear 1284 at the front end of the two double-ended threaded rods 1204, synchronously driving the double-ended threaded rods 1204 to rotate, ensuring that the moving ring 1202 moves symmetrically. The gear transmission has strong synchronization, ensuring consistent adjustment of the inner support mechanism 12 and avoiding core skewing. The motor drive enables automated adjustment, improving adaptation efficiency.

[0037] Example 9 Furthermore, a protective cover 30 is provided at the front end of the rotating rod 11, and the third drive unit 1208 is located inside the protective cover 30. A number of fixing screws 31 arranged in a ring array are threaded between the outer edge of the protective cover 30 and the front end of the rotating rod 11. A second heat dissipation port 32 is provided on the protective cover 30, and a second filter screen is provided inside the second heat dissipation port 32.

[0038] Those skilled in the art will understand that the protective cover 30 is mounted on the front end of the rotating rod 11 by fixing screws 31, enclosing the third drive unit 1208 inside. The second heat dissipation port 32 and the second filter achieve heat dissipation and dust prevention. This protects the gears and motor of the third drive unit 1208 from contamination by processing debris, extends the life of components, and the heat dissipation structure ensures its stable operation over a long period of time.

[0039] Example 10 Furthermore, the second drive unit 13 includes a third motor 1301 fixedly connected to the rear side of the housing 1. The third motor 1301 is electrically connected to the controller. A small pulley 1302 is fixedly connected to the output end of the third motor 1301. A large pulley 1303 is fixedly connected to the rear end of the rotating rod 11. A transmission belt 1304 is connected between the small pulley 1302 and the large pulley 1303.

[0040] Those skilled in the art will understand that when the controller starts the third motor 1301, the small pulley 1302 at its output end drives the large pulley 1303 at the rear end of the rotating rod 11 to rotate via the transmission belt 1304, causing the rotating rod 11 and the inner support mechanism 12 to rotate synchronously, thus completing the winding of the aluminum foil shielding paper. The belt drive operates smoothly with low noise, effectively transmits power, meets the speed requirements of the winding operation, and is adaptable to different winding speed requirements.
