[0019] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0020] The present invention provides Figure 1-4 A card issuing machine silo shown in the figure comprises a bottom plate 1, L-shaped fixing plates 2 are installed on both sides of the top of the bottom plate 1, a cover plate 3 is arranged between the tops of the L-shaped fixing plates 2 on both sides, a guide rail assembly 4 is arranged on the top of the cover plate 3, support frames 5 are also installed on the outside of the L-shaped fixing plates 2 on both sides, symmetrical mounting plates 6 are arranged on the tops of the supporting frames 5 on both sides, and an adjustment limit device 7 is also installed on the outside of the mounting plates 6, and a plurality of cards 8 are placed between the mounting plates 6 on both sides in cooperation with the top of the guide rail assembly 4; Furthermore, a baffle 61 is provided at one end of the mounting plates 6 on both sides, the card 8 is restricted by the baffle 61, and a feeding opening for the card 8 to pass through is left between one end of the support frame 5 and one end of the mounting plate 6; Furthermore, the inner sides of the L-shaped fixed plates 2 on both sides are set as storage bins 21, and an adjusting discharge component 9 is also provided inside the storage bin 21. The adjusting discharge component 9 passes through the storage bin 21 and the support frame 5.

[0021] In the present invention, the baffle 61 provided at one end of the mounting plates 6 on both sides can limit the card 8. The lower half of the baffle 61 is an arc curved outward, and the length exceeds the top height of the cover plate 3. This design can effectively prevent the card 8 from sliding off from one end of the mounting plate 6 during placement, ensuring that the initial position of the card 8 in the silo is accurate.

[0022] Furthermore, the guide rail assembly 4 includes a fixed block 41 installed on the top of the cover plate 3, a guide rail 42 is provided on the top of the fixed block 41, a limit assembly 43 is matched on the guide rail 42, and the limit assembly 43 moves on the guide rail 42 and limits the movement of the card 8.

[0023] Furthermore, the limiting assembly 43 includes a slider 431 that cooperates with the guide rail 42, a movable plate 432 is fixed to the top of the slider 431, a telescopic limiting plate 433 is provided at one end of the movable plate 432, the telescopic limiting plate 433 is arranged at one end of the movable plate 432, and is perpendicular to the guide rail 42 and fits on the back of the card 8.

[0024] Furthermore, the adjustment limit device 7 includes two groups of support seat assemblies 71 installed on both sides of the top of the support frame 5, each group of support seat assemblies 71 includes two support blocks 711, a fixing rod 712 is provided between the two support blocks 711, a fixing ring 713 is sleeved on the fixing rod 712, an S-shaped mounting plate 714 is provided on the top of the fixing ring 713, a plurality of mounting holes 715 are provided at the end of the S-shaped mounting plate 714, and a compression spring 716 is provided between the bottom fixing ring 713 and the rear end support block 711, the S-shaped mounting plates 714 on both sides are symmetrically arranged, and an adjustment assembly 72 is commonly installed on one side.

[0025] Furthermore, the adjustment component 72 includes two groups of adjustment grooves 721 installed on one side of the mounting hole 715. The two groups of adjustment grooves 721 are installed horizontally and have movable cross bars 722 installed inside. One side of the two groups of movable cross bars 722 is connected to an adjustment plate 723. A telescopic cylinder 724 is fixed to one side of the adjustment plate 723. A telescopic block 725 is connected to the bottom of the telescopic cylinder 724. Limit baffles 726 extend downward on both sides of the telescopic block 725. The limit baffles 726 act on the front of the card 8.

[0026] In the present invention, the adjustment limit device 7 is used to adjust the front position of the card 8. In the adjustment component 72 of the device, the telescopic cylinder 724 plays a key role. When the telescopic cylinder 724 is started, the telescopic block 725 is driven to move up and down. The limit baffles 726 extending downward on both sides of the telescopic block 725 change their positions as the telescopic block 725 moves, thereby adjusting the front position of the card 8.

[0027] Furthermore, in the adjustment and limiting device 7, the support seat assembly 71 provides support for the entire adjustment. Each group of support seat assemblies 71 includes two support blocks 711, a fixing rod 712 is provided between the two support blocks 711, and a fixing collar 713 is sleeved on the fixing rod 712. An S-shaped mounting plate 714 is provided on the top of the fixing collar 713, a plurality of mounting holes 715 are provided at the end of the S-shaped mounting plate 714, and a compression spring 716 is provided between the bottom fixing collar 713 and the rear end support block 711. This structure enables the S-shaped mounting plate 714 to move flexibly within a certain range during the adjustment process, and to maintain a stable limiting state after the adjustment is completed.

[0028] Furthermore, it is necessary to ensure that the card 8 can smoothly pass through the discharge port left between the support frame 5 and one end of the mounting plate 6. By adjusting the front position of the card 8 by the adjusting limit device 7 and limiting the back of the card 8 by the guide rail assembly 4, the stability of the card 8 in the silo can be ensured, so that the card 8 can approach the discharge port in a correct posture and be ready for smooth discharge.

[0029] Furthermore, the adjusting discharge assembly 9 includes an adjusting knob 91 arranged in the middle of a support frame 5 on one side, and a rotating shaft 92 is connected to one end of the adjusting knob 91. The rotating shaft 92 matches the moving shaft 93 arranged on the inner wall of the storage bin 21. The rotating shaft 92 rotates to drive the moving shaft 93 to move inside the storage bin 21, and a matching bearing 94 is provided on the support frame 5 at the other end. A fixed sleeve 95 is provided on the outside of the moving shaft 93 located inside the storage bin 21, and a push plate 96 is provided on one side of the fixed sleeve 95.

[0030] In the present invention, an adjusting knob 91 in the material discharging adjusting assembly 9 is used. When the adjusting knob 91 is turned, a rotating shaft 92 connected to one end thereof will rotate accordingly. Since the rotating shaft 92 matches the moving shaft 93 on the inner wall of the storage bin 21, the rotation of the rotating shaft 92 will drive the moving shaft 93 to move inside the storage bin 21. A fixed shaft sleeve 95 is provided outside the moving shaft 93, and a push plate 96 on one side of the fixed shaft sleeve 95 will adjust its position as the moving shaft 93 moves, thereby performing a material taking operation on the card 8 in the storage bin 21.

[0031] Stack the cards 8 horizontally and place them between the mounting plates 6 , ensuring that the cards 8 are located at the top of the guide rail assembly 4 , with the front of the cards 8 facing the limit baffle 726 of the adjustment limit device 7 , and the back of the cards 8 affixed to the telescopic limit plate 433 of the movable plate 432 of the guide rail assembly 4 .

[0032] Furthermore, a plurality of evenly spaced exhaust slots 61 are provided on the inner sides of the mounting plates 6 on both sides, and the cards 8 are stacked horizontally between the mounting plates 6 and located on the top of the guide rail assembly 4 .

[0033] Furthermore, the lower half of the baffle 61 is in an outwardly curved arc shape, and its length exceeds the top height of the cover plate 3 .

[0034] In the present invention, when the card 8 needs to be sent out, the limit assembly 43 on the guide rail assembly 4 starts to work. The slider 431 in the limit assembly 43 moves on the guide rail 42. Since a moving plate 432 is fixed on the top of the slider 431, the telescopic limit plate 433 at one end of the moving plate 432 will push the card 8 as the slider 431 moves. The telescopic limit plate 433 is perpendicular to the guide rail 42 and fits on the back of the card 8. This pushing method can ensure that the card 8 moves in the direction of the lower feed port in a predetermined direction. During the pushing process, the frontmost card 8 will be sent out through the feed port first and enter the next process of the card issuing machine.

[0035] In the present invention, by adjusting the adjustment assembly 72 on the mounting plate 6, the thickness and quantity of the card 8 can be fine-tuned. During the adjustment process, the moving crossbar 722 installed inside the adjustment slot 721 can move laterally in the adjustment slot 721, and the adjustment plate 723 connected to one side of the moving crossbar 722 will change position as the moving crossbar 722 moves. The positions of the telescopic cylinder 724, the telescopic block 725, and the limit baffle 726 fixed on one side of the adjustment plate 723 will also be adjusted accordingly, thereby achieving fine adjustment of the thickness and quantity of the card 8, ensuring that only one card is sent out each time, and preventing multiple cards from being sent out at the same time.

[0036] A method for using a card issuing machine silo comprises the following steps: S1. Operate and adjust the adjusting knob 91 in the discharging assembly 9. Since one end of the adjusting knob 91 is connected to the rotating shaft 92, and the rotating shaft 92 matches the moving shaft 93 on the inner wall of the storage bin 21, when the adjusting knob 91 is turned, the rotating shaft 92 will rotate accordingly, thereby driving the moving shaft 93 to move inside the storage bin 21. A fixed shaft sleeve 95 is provided outside the moving shaft 93, and a push plate 96 on one side of the fixed shaft sleeve 95 will adjust its position as the moving shaft 93 moves, thereby performing a material extraction operation on the card 8 in the storage bin 21.

[0037] Furthermore, the cards 8 are stacked horizontally and placed between the mounting plates 6, ensuring that the cards 8 are located at the top of the guide rail assembly 4. At this time, the front of the card 8 faces the limit baffle 726 of the adjustment limit device 7, and the back of the card 8 is attached to the telescopic limit plate 433 of the moving plate 432 of the guide rail assembly 4, and the card 8 is limited by the baffle 61 commonly set at one end of the mounting plates 6 on both sides. The lower half of the baffle 61 is an arc that bends outward, and its length exceeds the top height of the cover plate 3. This design can effectively prevent the card 8 from sliding off from one end of the mounting plate 6 during placement; S2. In order to ensure that the card 8 can smoothly pass through the feeding opening between the support frame 5 and one end of the mounting plate 6, the front position of the card 8 needs to be adjusted. The limit baffle 726 is moved by adjusting the telescopic cylinder 724 of the limit device 7. After the telescopic cylinder 724 is started, it will drive the telescopic block 725 to move up and down, and the limit baffles 726 extending downward on both sides of the telescopic block 725 will change their positions as the telescopic block 725 moves, thereby adjusting the front position of the card 8.

[0038] Furthermore, in the adjustment and limiting device 7, the support seat assembly 71 provides support for the entire adjustment. Each group of support seat assemblies 71 includes two support blocks 711, a fixing rod 712 is provided between the two support blocks 711, and a fixing ring 713 is sleeved on the fixing rod 712. An S-shaped mounting plate 714 is provided on the top of the fixing ring 713, a plurality of mounting holes 715 are provided at the end of the S-shaped mounting plate 714, and a compression spring 716 is provided between the bottom fixing ring 713 and the rear end support block 711. This structure enables the S-shaped mounting plate 714 to move flexibly within a certain range during the adjustment process, and to maintain a stable limiting state after the adjustment is completed; S3. When the card 8 needs to be sent out, the limit assembly 43 on the guide rail assembly 4 starts to work. The slider 431 in the limit assembly 43 moves on the guide rail 42. Since a moving plate 432 is fixed on the top of the slider 431, the telescopic limit plate 433 at one end of the moving plate 432 will push the card 8 as the slider 431 moves. The telescopic limit plate 433 is perpendicular to the guide rail 42 and fits on the back of the card 8. This pushing method can ensure that the card 8 moves in the predetermined direction toward the lower feed port. During the pushing process, the frontmost card 8 will be sent out through the feed port first and enter the next process of the card issuing machine; S4. By adjusting the adjustment component 72 on the mounting plate 6, the thickness and quantity of the card 8 can be fine-tuned. During the adjustment process, the moving crossbar 722 installed inside the adjustment slot 721 can move laterally in the adjustment slot 721, and the adjustment plate 723 connected to one side of the moving crossbar 722 will change position as the moving crossbar 722 moves. The positions of the telescopic cylinder 724, the telescopic block 725, and the limit baffle 726 fixed on one side of the adjustment plate 723 will also be adjusted accordingly, thereby achieving fine-tuning of the thickness and quantity of the card 8, ensuring that only one card is sent out each time, and preventing multiple cards from being sent out at the same time; S5. Regularly check whether the movement of the guide rail assembly 4 and the limit assembly 43 is smooth. Check whether the sliding block 431 slides smoothly on the guide rail 42, and whether the moving plate 432 and the telescopic limit plate 433 are worn or damaged. Check and adjust the various components of the discharging assembly 9 and the adjusting limit device 7. For example, check whether the adjusting knob 91 can rotate normally, whether the rotating shaft 92 and the moving shaft 93 cooperate well, whether the telescopic cylinder 724 works normally, whether the push plate 96 can push the card 8 normally, etc. At the same time, check whether the screws and fixings need to be tightened to ensure the stability of the entire silo structure and the normal operation of each component.

[0039] In the present invention, during the card placement process, by adjusting the material taking operation of the discharge assembly 9, the limiting of the baffle 61, and the positioning function of the guide rail assembly 4 and the adjusting limiting device 7, the card 8 can be accurately placed at the predetermined position between the mounting plates 6 and remain stable in the silo without shaking, tilting or misalignment.

[0040] Furthermore, during the card discharging process, due to the push of the guide rail assembly 4 on the back of the card 8 and the limitation of the front of the card 8 by the adjustment limit device 7, the card 8 can be sent out through the discharge port in a precise direction, ensuring the accuracy of entering the next process of the card issuing machine.

[0041] In the present invention, by fine-tuning the thickness and quantity of the cards 8 by the adjusting component 72, it can be reliably ensured that only one card is sent out each time. This precise control avoids the situation where multiple cards are sent out at the same time, and improves the discharge accuracy of the card issuing machine.

[0042] Furthermore, since the card 8 is accurately positioned in the hopper, moves smoothly, and can be discharged in a predetermined manner and sequence, the entire discharge process is efficient and orderly, thereby improving the discharge efficiency of the card issuing machine.

[0043] Furthermore, since the structural design of the silo facilitates the inspection of each component, problems such as wear, damage or looseness of the guide rail assembly 4, the limit assembly 43, the adjusting discharging assembly 9 and the adjusting limit device 7 can be discovered in time. This allows the fault point to be quickly located and repaired, reducing the downtime of the card issuing machine caused by silo failure and improving the overall operating efficiency of the card issuing machine. The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
