Description

Technical Field

[0001] This utility model relates to the field of stamping machine technology, and in particular to an anti-aircraft cover structure for a double-stamping machine. Background Technology

[0002] Currently, dual-stamp machines are automated devices used to simultaneously or sequentially affix two stamps to documents, invoices, or cards. They are mainly used in scenarios requiring high security and efficiency, such as finance, government affairs, and logistics. Existing dual-stamp machines currently face the following technical challenges:

[0003] 1. Traditional equipment relies on a single protection method (such as mechanical locking or independent photoelectric detection), which leads to security vulnerabilities. Pure mechanical locking is easily physically damaged or bypassed, and cannot identify abnormal situations in a timely manner. Pure photoelectric detection is easily affected by environmental interference (such as strong light or color mark contamination) and lacks physical blocking capabilities, so it cannot completely intercept misoperation.

[0004] 2. Traditional transmission systems (such as single-sided gear or linkage structures) have design flaws: the movement of the actuators (such as stops and gates) is not synchronized, causing the mechanism to jam or deviate; the lack of sensor feedback and real-time linkage with the power system makes it impossible to dynamically adjust under abnormal resistance, which can easily lead to equipment damage.

[0005] Therefore, an anti-aircraft cover structure for a double-stamping machine is needed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide an anti-aircraft cover structure for a double-stamp machine. This invention constructs a multi-layered safety protection system through the deep synergy of mechanical forced locking and photoelectric dynamic verification. The anti-aircraft cover block forcibly isolates the stamp path in the non-operational state. Combined with the access control of the barrier gate, a basic physical protective barrier is formed, which can effectively prevent misoperation.

[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: an anti-air cover structure for a double stamping machine, which is installed inside the double stamping machine and includes an anti-air cover, an anti-air cover limit switch shaft, a rack and a gear;

[0008] A card is installed inside the air raid shelter, and the card is inserted into the air raid shelter. The gear and rack are both installed at the rear end of the air raid shelter. A first servo motor is connected to the gear. There are two racks, which are respectively located on the left and right sides of the gear. The racks and gear are meshed with each other. An air raid shelter stop block for limiting the position of the air raid shelter is fixedly connected to the end of the rack.

[0009] Furthermore, the air raid shelter is equipped with an opening mechanism, which includes:

[0010] The door opening limit switch control board is fixed on the air raid shelter cover and electrically connected to an external power source;

[0011] The optical sensor control board is fixed on the air raid shelter cover;

[0012] The stamping machine's gate is slidably connected to the top guide rail of the air raid shelter cover, and a gear transmission assembly is connected to the bottom of the stamping machine's gate.

[0013] The second servo motor is driven and connected to one side of the gear transmission assembly:

[0014] The door opening limit switch control board is electrically connected to the optical sensor control board and the second servo motor, respectively.

[0015] Furthermore, an air raid cover limit switch control board is fixedly connected to the rear end of the air raid cover.

[0016] Furthermore, a card limiting rib is fixedly connected to the air raid shelter cover, which is used to limit the card.

[0017] Furthermore, an anti-aircraft cover limit switch is installed at the bottom of the card limiting rib.

[0018] Furthermore, a pressure bar is installed on the dual-stamp machine.

[0019] Furthermore, a photoelectric switch and bracket are installed at the tail of the stamping mechanism of the double-stamp machine.

[0020] The advantages of this utility model are:

[0021] 1. This utility model constructs a multi-layered safety protection system through the deep synergy of mechanical forced locking and photoelectric dynamic verification. The anti-aircraft cover block forcibly isolates the stamp path in the non-operational state. Combined with the access control of the barrier door, it forms a basic physical protection barrier, which can effectively prevent misoperation.

[0022] 2. The symmetrical gear and rack structure in this utility model realizes bidirectional synchronous motion control, ensuring the consistency of the actions of key actuators (stamping machine stop block, stop gate); this utility model forms a real-time feedback link with the servo motor power system through photoelectric sensor control, dynamically adjusting the motion state of the mechanism, taking into account both operational efficiency and equipment protection.

Figure 7 This is a schematic diagram of the structure of the air raid shelter in this utility model. Figure 2 ,like Figures 1 to 7The invention illustrates an anti-aircraft cover structure for a double-stamp machine, installed inside the machine. It includes an anti-aircraft cover 301, an anti-aircraft cover travel switch shaft, a rack 304, and a gear 305. An anti-aircraft cover travel switch control board 302 is fixedly connected to the rear end of the cover 301. A card limiting rib 9 is fixedly connected to the cover 301, used to limit the insertion path of the card 12 and ensure accurate timing of the card 12 triggering the door opening travel switch. An anti-aircraft cover travel switch 303 is installed at the bottom of the card limiting rib 9. A pressure rod 10 is installed on the double-stamp machine, and a through-beam switch 8 and a bracket 7 are installed at the tail of the stamping mechanism 6.

[0043] The anti-aircraft cover 301 in this invention serves as the main mechanical protection unit, supporting key components such as the anti-aircraft cover block 5 and the limit switch. It restricts the movement of the stamping mechanism 6 through physical obstruction. When the cover is closed, the internal anti-aircraft cover block 5 remains extended, preventing the stamping mechanism 6 from pressing down and avoiding accidental stamping when there is no medium. The anti-aircraft cover limit switch shaft is linked to the movement of the anti-aircraft cover block 5, converting mechanical displacement into an electrical signal. When the card 12 is inserted into place, the shaft retracts with the anti-aircraft cover block 5, triggering the anti-aircraft cover limit switch 303 and providing a start signal to the servo motor.

[0044] This utility model includes a card 12 inside the air raid cover 301, which is inserted into the air raid cover 301. The gear 305 and rack 304 are both installed at the rear end of the air raid cover 301. A first servo motor 306 is connected to the gear 305. Two racks 304 are provided, which are respectively located on the left and right sides of the gear 305. The racks 304 and gear 305 are meshed with each other. An air raid cover block 5 for limiting the position of the air raid cover 301 is fixedly connected to the end of the rack 304.

[0045] This invention utilizes a gear 305 and a rack 304 to form a bidirectional linear transmission mechanism. The gear 305, driven by a first servo motor 306, meshes with the symmetrically distributed racks 304 on both sides, converting the rotational motion of the first servo motor 306 into the linear extension and retraction motion of the air raid sump block 5, ensuring that the air raid sump block 5 retracts or extends synchronously. The first servo motor 306 in this invention starts upon receiving a signal from the air raid sump limit switch 303, and precisely controls the position movement of the air raid sump block 5 through the meshing transmission of the gear 305 and rack 304. Its stall torque characteristic can detect mechanical jamming, and in conjunction with the through-beam switch 8, it achieves overload protection.

[0046] The anti-aircraft cover block 5 in this invention can switch between two states: Extended state: blocks the movement path of the stamping mechanism 6, forcing physical isolation; Retracted state: releases the restriction on the stamping mechanism 6, allowing the pressure rod 10 to press down for stamping. The door opening limit switch control board 11 in this invention integrates a power management module. When the card 12 touches the door opening limit switch, it distributes power to the light sensor control board 13 and the second servo motor 16, and transmits the color recognition result signal to coordinate the opening and closing of the door. The light sensor control board 13 in this invention is equipped with an RGB spectrum analysis sensor, which can extract features from the printed color mark on the top of the card 12, compare it with the preset color code, and output the judgment result to the second servo motor 16. The second servo motor 16 can drive the door action according to the color recognition result: Recognition matching: forward rotation of the drive gear 305 opens the door. Recognition mismatch: remains stationary or reverse self-locks, maintaining the door closed. The stamping machine door 14 in this invention achieves lateral sliding through the drive gear transmission assembly of the second servo motor 16: Open state: forms a card 12 insertion channel. Closed state: Physically seals the equipment entrance. The air raid shelter limit switch 303 in this utility model can detect whether the card 12 is inserted in place. After being triggered, it performs two functions: illuminates the operation indicator light, provides visual feedback, sends an electrical signal to start the first servo motor 306, and releases the restriction of the air raid shelter block 5.

[0047] In this invention, the photoelectric switch 8 and the bracket 7 are installed at the tail of the stamp mechanism 6, forming a photoelectric detection system. When the bracket 7 enters the detection area of ​​the photoelectric switch 8 as the stamp is pressed down, the stamp position is fed back in real time: when the bracket 7 is detected, the power supply to the first servo motor 306 is immediately cut off to prevent motor stall caused by the anti-aircraft cover block 5 not being fully retracted. When the bracket 7 is not detected, the anti-aircraft cover block 5 remains extended. This invention can transmit the downward pressure of the pressure rod 10 to the stamp mechanism 6. Its movement is constrained by the position of the anti-aircraft cover block 5: when the anti-aircraft cover block 5 retracts, the pressure rod 10 is allowed to press down in its full stroke to complete the stamping. When the anti-aircraft cover block 5 extends, the pressure rod 10 is mechanically blocked from moving downward, forming a rigid anti-misoperation protection.

[0048] This utility model features an opening mechanism installed on an air raid shelter cover 301. The opening mechanism includes: an opening limit switch control board 11, fixed to the air raid shelter cover 301 and electrically connected to an external power source; a light sensor control board 13, fixed to the air raid shelter cover 301; a stamping machine stop door 14, slidably connected to the top guide rail of the air raid shelter cover 301, with a gear transmission assembly connected to the bottom of the stamping machine stop door 14; and a second servo motor 16, driving one side of the gear transmission assembly. The opening limit switch control board 11 is electrically connected to the light sensor control board 13 and the second servo motor 16. When the card 12 triggers the opening limit switch, the light sensor activates color recognition. The recognition signal is transmitted through the light sensor control board to the second servo motor 16, driving the gear transmission assembly to move the stop door laterally.

[0049] Work process description:

[0050] Phase 1: Device Standby State

[0051] Door Closure: The second servo motor 16 remains in its initial position, and the stamping machine door 14 is closed by meshing the bottom rack 304 with the gear 305, completely covering the card 12 insertion port. Anti-aircraft Cover Block 5 Extension: With the first servo motor 306 de-energized, the gear 305 meshes with and is fixed to the racks 304 on both sides, and the anti-aircraft cover block 5 is in the extended position, physically blocking the movement path of the stamping mechanism 6. Indicator Light Display: The indicator light on the operation panel is red, indicating that the device is in standby and inoperable mode.

[0052] Phase Two: Card 12 Access Verification

[0053] Triggering the door opening limit switch: Insert card 12 along the card limiting rib 9. When the front end of card 12 touches the door opening limit switch, the following actions are triggered: The door opening limit switch control board 11 is powered on, activating the light sensor control board 13. The RGB light sensor starts and performs a spectral scan on the color mark on the top of card 12. Color recognition judgment: Match successful: The light sensor control board sends a signal to the second servo motor 16, driving the gear transmission assembly to slide the barrier door laterally open, exposing the card 12 channel, and the indicator light turns green. Match failed: The barrier door remains closed, the indicator light flashes red as an alarm, and card 12 is refused insertion.

[0054] Phase 3: Card 12 Insertion and Security Preparation

[0055] Card 12 fully inserted: Continue pushing card 12 to the bottom of card limit rib 9, triggering the anti-aircraft cover travel switch 303, and performing the following operations: The anti-aircraft cover travel switch control board 302 is energized, sending a start signal to the first servo motor 306. The first servo motor 306 drives the gear 305 to rotate, causing the racks 304 on both sides to retract synchronously. The anti-aircraft cover stop 5 retracts into the device, releasing its obstruction to the stamping mechanism 6. The operation indicator light turns yellow, indicating that the stamping operation can be performed.

[0056] Phase Four: Stamping and Implementation, and Prevention of Blockade and Transfer Protection

[0057] When the pressure lever 10 is pressed, the system performs dual verification: Mechanical verification: the anti-aircraft cover block 5 has retracted, allowing the pressure lever 10 to move downwards. Photoelectric verification: the tail bracket 7 of the stamp mechanism 6 enters the detection area of ​​the photoelectric switch 8 as it is pressed down. After the photoelectric switch 8 detects the bracket 7 entering, it immediately cuts off the power to the first servo motor 306. If the bracket 7 is not detected to be in place (the anti-aircraft cover block 5 is not fully retracted), the system forcibly terminates the pressing action of the pressure lever 10. Stamping completed: the pressure lever 10 transmits pressure to the stamp mechanism 6, completing the double stamping of the card 12. During the reset process of the stamp mechanism 6, the bracket 7 disengages from the detection area of ​​the photoelectric switch 8, and the first servo motor 306 is re-energized.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
