The snap-fit ​​station 405a on the upper rotating pulley 402 is located at the top and one side, while the snap-fit ​​station 405a on the lower rotating pulley 402 is located at the bottom and the other side. The two rotating pulleys 402 are coaxially aligned with the semi-circular arc-shaped grooves at both ends of the back guide groove 203. When the electromagnets 4056 on the two fixed cylinders 4051 at the snap-fit ​​station 405a position of the two rotating pulleys 402 are energized, the corresponding insertion rods 4053 can be inserted into the slots 305 on the back guide post 304 on the back of the corresponding storage box 301, and the upper and lower rotating pulleys 402 can be driven to rotate synchronously. This allows multiple newspaper and magazine storage components 3 to be pushed along the back guide groove 203, moving the required newspaper and magazine storage components 3 to the empty slot area for newspaper and magazine loading and unloading.

[0023] The bottom support assembly 5 includes two sliding grooves 501 symmetrically opened on the movable base 1. A sliding seat 502 is slidably installed inside the sliding groove 501. A support platform 503 is fixedly installed on the top of the sliding seat 502. The two support platforms 503 respectively support the bottom of the newspaper storage assemblies 3 arranged in rows on both sides. A double-ended screw 504 is rotatably installed inside the sliding groove 501. The two sliding seats 502 are respectively threaded to two threaded grooves with opposite thread directions on the double-ended screw 504. One end of the double-ended screw 504 is fixedly connected to the output shaft of the fourth motor 505. The fourth motor 505 is fixedly installed on the movable base 1.

[0024] Working principle: During use, the equipment is moved near the newspaper printing equipment. Since the bottom newspaper storage component 3 corresponds to the removal slot area at the bottom of the front panel 204, the second motor 3096 is activated to drive the fifth gear 3095 to rotate. The fifth gear 3095 meshes with the fourth gear 3094 on the rotating screw 3093, thereby driving the rotating screw 3093 to rotate. Since the rotating screw 3093 is threadedly connected to the movable plate 3091, the movable plate 3091 moves along the movable cavity 307, causing the sealing door 302 to move away from the storage box 301, opening the storage box 301 and driving the conveyor belt 30 82 moves outward, and when the first motor 3088 is turned on, it can drive the third gear 3087, the second gear 3086 and the first gear 3085 to rotate, driving the conveyor belt 3082 to move, so that the newspapers and magazines to be stored can be fed to the position corresponding to the storage cavity 306. Then, the movable plate 3091 is controlled to move back, so that the newspapers and magazines can be moved into the storage cavity 306 for storage. The newspapers and magazines are stored in the storage cavity 306, which reduces contact with air and plays a role in moisture prevention and fire prevention. When it is necessary to take out the newspapers and magazines from the storage cavity 306, the sealing door 302 is moved outward, and the conveyor belt 3082 is controlled to move to output the newspapers and magazines. After the bottom newspaper storage component 3 completes the newspaper input or output, it is necessary to drive multiple newspaper storage components 3 to move in a cycle once, so that another newspaper storage component 3 moves to the bottom position. First, the fourth motor 505 is turned on to drive the double-headed screw 504 to rotate. Since the two sliding seats 502 are respectively threaded to the threaded grooves with opposite directions on the double-headed screw 504, the two support platforms 503 are driven to move away from each other, thus moving away from below the vertical newspaper storage components 3 on both sides. Then, the electromagnets 4056 on the two fixed cylinders 4051 at the snap-fit ​​position 405a on the two rotating pulleys 402 are energized. The two fixed cylinders 4051 at the snap-fit ​​position 405a on the upper rotating pulley 402 are located at the top and one side, while the two fixed cylinders 4051 at the snap-fit ​​position 405a on the lower rotating pulley 402 are located at the bottom and the other side. After the electromagnet 4056 is energized, it generates a repulsive force on the magnetic block 4055, pushing the insertion rod 4053 into the slot 305 in the guide post 304 on the back of the corresponding storage box 301. Then, the third motor 408 is turned on, driving the seventh gear 407 to rotate. This, in turn, drives the lower rotating pulley 402 to rotate clockwise via the sixth gear 406. Subsequently, the upper rotating pulley 402 rotates clockwise synchronously via the transmission belt 403. Since the width of the storage box 301 is smaller than the width of the middle fixing plate 206, during the rotation of the two rotating pulleys 402, the topmost newspaper storage component 3 in the vertical row on one side is driven to move along the back guide groove 203. The newspaper storage component 3 moves upward, while the topmost newspaper storage component 3 moves along the back guide slide 203 to the topmost position of the newspaper storage component 3 arranged in the other column. The bottommost newspaper storage component 3 arranged in the other column moves to the position of the empty slot area. The newspaper storage component 3 originally located in the position of the empty slot area moves along the back guide slide 203 to the bottommost position of the newspaper storage component 3 arranged in the one column. This realizes the cyclical movement of multiple newspaper storage components 3, continuously moving one of the newspaper storage components 3 to the position of the empty slot area, which facilitates the loading and unloading of newspapers and magazines and facilitates automatic loading, unloading and stacking. It should be noted that the pulley 402 rotates 90 degrees each time it rotates. After the movement is complete, the two support platforms 503 are moved back to support the bottom of the two rows of newspaper storage components 3. At the same time, the bottom of the bottommost newspaper storage component 3 contacts the movable base 1 to achieve support. The upper and lower surfaces of the two rows of newspaper storage components 3 contact the support in sequence. The topmost newspaper storage component 3 is supported by the front guide groove 205 supporting the sealing door 302 and the back guide groove 203 supporting the back guide column 304, so that each newspaper storage component 3 can be supported and storage stability is guaranteed.
