It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] Example 1

[0023] The present invention provides a storage device for a document storage cabinet, such as Figure 1 As shown, it includes a storage mechanism and a motor device 6 for driving the storage mechanism to rotate.

The self-aligning ball bearing 19 can automatically adjust its direction as the center of gravity of the storage disc 2 shifts. A movable protective mechanism 9 is also provided on the outside of the motor device 6. A rebound component is provided between the side of the motor device 6 away from the circular gear and the movable protective mechanism 9. When the document is stuck and the rotation of the storage disc 2 is obstructed, the driving gear 5 of the motor device 6 interferes with the annular gear 4. At this time, under the action of the rebound component, the motor device 6 will repeatedly rebound on the movable protective mechanism 9. As a result, the sensor provided in the motor device 6 detects an increase in the motor current load and sends a command to the single-chip microcomputer. The single-chip microcomputer processes and controls the motor to stop operating, and then the storage disc 2 stops rotating, thereby protecting the document from damage.

[0024] In the embodiment of the present utility model, Figure 2As shown, multiple balancing mechanisms 3 provided on the base plate 1 include a base 10 fixed to the base plate 1 by screws and a sleeve assembly provided above the base 10, the sleeve assembly includes an outer sleeve 11 and an inner accommodating cavity, a screw 13 is passed through the inner accommodating cavity, one end of the screw 13 is connected to the base 10, and the other end passes through the bottom of the inner accommodating cavity, and the screw 13 is threadedly connected to the outer sleeve 11, a mounting seat 12 is provided in the inner accommodating cavity, and a mounting groove is provided on the top of the mounting seat 12, a roller 8 is installed in the mounting groove, and the roller 8 is engaged with the annular gear in the storage disc 2 The wheel 4 is connected in a rolling manner, and one end of the screw 13 passes through the inner accommodating cavity and is in contact with the bottom of the mounting seat 12; the height of the mounting seat 12 is adjusted by rotating the screw 13 to adjust the height of the end of the screw 13 and the bottom of the inner accommodating cavity. When the center of gravity of the storage disc 2 shifts due to uneven storage of documents, the roller 8 supports and balances the annular gear 4 of the storage disc 2, thereby ensuring that the entire storage disc 2 remains balanced, effectively avoiding the problem of low document transmission accuracy caused by shaking and tilting of the storage disc 2, thereby greatly improving the reliability of storage.

[0025] In the embodiment of the present utility model, Figure 3 and Figure 4 As shown, the movable protection mechanism 9 provided on the outside of the motor device 6 includes an L-shaped support frame, and the support frame includes a horizontal plate 14 and a vertical plate 15. The horizontal plate 14 and the vertical plate 15 are fixedly mounted on the bottom plate 1, and a groove is provided on the horizontal plate 14. The bottom of the motor device 6 is provided in the groove. There are mounting holes on both sides of the horizontal plate 14. A shaft is installed in the mounting hole, and the shaft is connected to the motor device 6; the vertical plate 15 is provided on the side of the motor device 6 away from the ring gear 4, and the rebound component is provided between the vertical plate 15 and the motor device 6. The rebound component includes a mounting column 16 and a torsion spring 17. The mounting column 16 is provided on the motor device 6, and the torsion spring 17 is installed on the mounting column 16, and the torsion arm of the torsion spring 17 is clamped between the motor device 6 and the vertical plate 15; during the document access process, when the document is stuck, the rotation of the storage disc 2 is blocked, and the driving gear 5 of the motor device 6 interferes with the ring gear 4. At this time, under the action of the torsion spring 17 in the movable protection mechanism 9, the motor device 6 will repeatedly rebound on the movable protection mechanism 9, thereby the sensor inside the motor device 6 receives the increase in the motor current load, and at this time sends a command to the single-chip microcomputer, which processes and controls the motor to stop operating, and then the storage disc 2 stops rotating, thereby protecting the document from being damaged.

[0026] When the document rotates with the storage disk 2, in order to prevent the document from being displaced on the storage disk 2 due to factors such as centrifugal force, thereby increasing the friction and affecting the life of the motor; in this embodiment of the utility model, Figure 5As shown, a top cover 7 is provided on the top of the storage disc 2. The top cover 7 is a cylinder with an open bottom. A notch is provided on one side of the top cover 7 for the passage of documents. A protrusion 18 is provided circumferentially on the inner wall of the top cover 7. The cross-sectional shape of the protrusion 18 is semicircular, and a convex ring is provided around the outer wall of the bottom of the top cover 7. The purpose of providing the protrusion 18 on the inner wall of the top cover 7 is to reduce the friction of the document, and can limit the movement of the document in multiple directions, ensuring that the document is always firmly on the storage disc 2 during high-speed rotation, thereby improving the safety and reliability of the storage device under complex operating conditions.

[0027] Furthermore, in the embodiment of the present utility model, if Figure 6 and Figure 7 As shown, a first mounting platform 22 is provided on the top of the top cover 7, an infrared transmitter 24 is provided on the first mounting platform 22, a second mounting platform 23 is provided on the bottom plate 1, an infrared receiver 25 is provided on the second mounting platform 23, the storage disc 2 includes a plurality of card plates distributed in an annular array, the gaps between adjacent card plates are used as storage space for storing documents, a support disc 20 is provided at the bottom of the storage disc 2, a ring gear 4 is provided at the bottom of the support disc 20, and a ring array of perforations 21 is provided on the support disc 20, the perforations 21 correspond to the gaps one by one, so that the infrared rays of the infrared transmitter 24 pass through the gaps and the perforations 21, and the infrared receiver 25 can receive the infrared rays; when the document When the storage disk 2 rotates to the preset position, the preset position is the position where the document blocks the infrared rays emitted by the infrared transmitter 24. At this time, the infrared rays emitted by the infrared transmitter 24 are blocked by the document, so that the infrared rays cannot pass through the perforation 21 to reach the infrared receiver 25, and then the infrared receiver 25 cannot receive the infrared rays. At this time, the infrared receiver 25 sends an instruction to the microcontroller, and the microcontroller controls the motor device 6 to stop running or control the motor device 6 to change the direction, so that the document stops accurately at the preset position, preventing the document from being delivered incompletely or over-delivered, and can eliminate problems such as document damage and equipment collision caused by uncontrolled transmission, thereby ensuring the smooth progress of the document storage and access process.

[0028] The beneficial effects of the embodiment of the utility model are as follows: by arranging multiple balancing mechanisms on the bottom plate, the rollers in the balancing mechanisms are connected in a rolling manner to the bottom of the annular gear in the storage mechanism, and the height of the rollers in the mounting seat can be adjusted by rotating the screw. When the storage disc of the storage mechanism has uneven distribution of stored documents and causes the center of gravity to shift and shake, the balancing mechanism can maintain the overall balance of the storage disc, and effectively avoid the document transmission accuracy caused by shaking and tilting of the storage disc; by arranging a movable protection mechanism on the outside of the motor device, when the document is stuck, the motor device repeatedly rebounds on the movable protection mechanism under the action of the torsion spring, so that the internal sensor of the motor detects that the motor current load increases, and at this time sends a command to the single-chip microcomputer to control the stop of storage. The operation of the storage device is improved, thereby protecting the document from damage; the friction of the document is reduced by the protrusion arranged on the inner wall of the top cover, ensuring that the document is always firmly on the storage disc during high-speed rotation, thereby improving the safety and reliability of the storage device under complex operating conditions; the infrared light emitted by the infrared transmitter arranged on the top of the top cover can pass through the gap of the storage disc and the perforation of the support disc, so that the infrared receiver arranged on the bottom plate can receive the infrared light, so that when the document reaches the preset position, the document can block the infrared light, so that the infrared receiver cannot receive the infrared light. At this time, the infrared receiver sends a command to the single-chip microcomputer, and the single-chip microcomputer controls the motor device to stop running or control the motor device to change the direction, so that the document stops accurately at the preset position, preventing the document from being delivered in place or over-delivered.
