The shaft B30 is made of alloy steel and is slidably connected to two linkage blocks 31 on the outside. The linkage blocks 31 can rotate flexibly on the shaft B30. The two linkage blocks 31 are fixedly connected to the connecting rods D32 by bolts. The connecting rods D32 are made of aluminum alloy profiles and are fixedly connected to the ends of acrylic front covers 25 by bolts. The surface of the acrylic front cover 25 is hardened to effectively prevent scratches.
[0029] Reference Figures 5 to 7In this embodiment, a lock head 27 is fixedly connected to the right front side of the housing 1. The lock head 27 is made of stainless steel casting with a polished surface and has a circular hole in the center. This hole is used to cooperate with the latch 26 to achieve the locking function.

Users can issue extraction commands and control the device's operation by pushing or pulling the handle 34. A protective ring 13 is bolted to the inside of the housing 1. The protective ring 13 is made of high-strength plastic and has a cylindrical structure. Its front exterior is slidably connected to the acrylic front cover 25, forming a closed space that effectively protects the internal mechanism from external interference. Elastic deceleration brushes 14 are fixed to both sides of the inner side of the protective ring 13. The elastic deceleration brushes 14 are made of silicone material, possessing good elasticity and wear resistance, and their outer edges are smoothly chamfered. The rotating plate 11 can be positioned to prevent the blind box from being unable to be removed properly. The protective ring 13 is internally slidably connected to the outside of the rotating plate 11, providing guidance and support for the rotation of the rotating plate 11. The bottom of the protective ring 13 has a delivery hole 24, the size of which is slightly larger than the maximum size of the blind box, ensuring that the blind box can pass through smoothly. Ten rotating plates 11 are fixedly connected to the left side of the shaft a9 by a key. The rotating plates 11 are made of aluminum alloy sheet, have a fan-shaped structure, and are anodized, which has good corrosion resistance and aesthetics. A partition 12 is welded to the bottom of every two rotating plates 11 on opposite sides. The partition 12 is made of hard plastic, and its height can be adjusted according to the size of the blind box, used to separate adjacent blind boxes.To prevent the blind boxes from colliding with each other during rotation, a sliding plate 22 is slidably connected to the top of every two rotating plates 11 on opposite sides. The sliding plate 22 is made of stainless steel with a smooth surface and can slide horizontally inside the rotating plate 11. An iron block 23, made of low-carbon steel, is welded to the front exterior of the sliding plate 22 and interacts with the magnetic force generated by the electromagnet 17 to control the movement of the sliding plate 22. The rear sides of all ten rotating plates 11 are bolted to the front side of a cover plate 21. The cover plate 21 is made of cast iron, providing high strength and stability. A speed sensor 10 is bolted to the rear side of the cover plate 21. The speed sensor 10 monitors the rotation speed of the rotating plates 11 in real time and transmits a signal to the electric push rod 15 when needed. The interior of the cover plate 21 is fixedly connected to the exterior of the shaft a9 via an interference fit, allowing the cover plate 21 to rotate synchronously with the shaft a9, thereby driving all the rotating plates 11 to rotate.
[0030] Working principle: In the workflow of the multi-layer blind box random extraction device, the blind box filling preparation work is carried out first. The blind box is placed between every two rotating plates 11, and the blind box is supported by the partition plate 12. The slide plate 22 can cooperate with the iron block 23 and the subsequent electromagnet 17 to realize the extraction of the blind box. The rear of the ten rotating plates 11 is fixed to the front of the cover plate 21. The cover plate 21 is fixedly connected to the shaft a9, so that the rotating plates 11 can rotate under the drive of the shaft a9. At the same time, the speed sensor 10 can monitor the rotation of the rotating plates 11. 1. Rotation speed: When a user needs to draw a blind box, they insert coins into the coin-operated plate 35. In case of equipment failure, the coins will fall into the tray 36. Then, the user issues a drawing command through the handle 34 in the control panel 33. At this time, the servo motor 5 starts, and its drive end drives the active wheel 6 to rotate. The active wheel 6 meshes with three driven wheels 7, which in turn drive the three driven wheels 7 to rotate. The driven wheels 7 mesh with the gear ring 8, causing the gear ring 8 to rotate. The shaft a9 fixed on the rear side of the gear ring 8 rotates accordingly. The shaft a9 drives the rotating plate 11 to rotate, realizing the random rotation selection of the blind box. The speed sensor 10 monitors the rotation speed of the shaft a9 in real time to ensure that the rotation process is stable and controllable. When the speed of the shaft a9 is detected to be zero, the electric push rod 15 starts, and its drive end pushes the connecting rod a16 forward. The electromagnet 17 at the left end of the connecting rod a16 moves forward accordingly. The electromagnet 17 is energized and generates magnetism, attracting the iron block 23 on the front side of the slide plate 22, causing the slide plate 22 to slide backward, so that the blind box loses its top position. Simultaneously, connecting rod a16 slides within slide 18, and the limiting ring 19 outside slide 18 remains stable under the support of connecting rod b20, ensuring smooth movement of connecting rod a16. After the blind box is unrestrained, it falls from the delivery hole 24 inside the protective ring 13 under the action of gravity, passes through the retrieval compartment 37, and the user can retrieve the blind box through the retrieval compartment 37. Furthermore, the baffle 38 on the front side of the retrieval compartment 37 can effectively prevent the blind box from falling to the ground and causing damage, thus completing the entire blind box retrieval process.
[0031] When maintaining the device or replenishing the blind box, the locking buckle 26 can be operated to slide it out from the outside of the lock head 27, thereby releasing the lock on the acrylic front cover 25. The acrylic front cover 25 is connected to the linkage block 31 through the connecting rod d32. The linkage block 31 can slide outside the shaft b30, thereby realizing the opening and closing of the acrylic front cover 25, which facilitates the operation of the device. The protective ring 13 is slidably connected to the acrylic front cover 25 on the front outside. The elastic deceleration brushes 14 on both sides of the inner side can play a buffer deceleration role when the acrylic front cover 25 is opened and closed. The outer edge of the elastic deceleration brushes 14 is designed with a smooth chamfer to avoid scratching the parts.
[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
