Description

Technical Field

[0001] This utility model relates to the field of self-service ticket vending machine technology, and in particular to a ticket dispensing mechanism for a self-service ticket vending machine. Background Technology

[0002] Lottery tickets are mostly sold through self-service ticket machines, and the ticket issuing agency is a crucial component of these machines.

[0003] To prevent tickets from falling directly from the dispensing slot just before being conveyed out, existing self-service ticket vending machines often have a conveyor wheel-type dispensing mechanism that automatically stops rotating under these conditions. However, because the conveyor wheels are aligned and in contact with each other, they cannot move to release the ticket just before it is conveyed out. As a result, when the ticket is pulled out from between the conveyor wheels, it may be torn by the squeezing friction between the conveyor wheels and the pulling force of the ticket being pulled out, thus damaging the ticket. Utility Model Content

[0004] In view of this, the present invention provides a ticket dispensing mechanism for a self-service ticket vending machine to solve the problem that when the ticket is pulled out from between the conveyor wheels, the ticket may be torn by the squeezing friction between the conveyor wheels and the pulling force of the ticket being pulled out, thus damaging the ticket.

[0005] The technical solution proposed by this utility model is: a ticket dispensing mechanism for a self-service ticket vending machine, specifically including two symmetrically arranged U-shaped retaining frames, and two vertically arranged mounting plates are symmetrically welded between the opening ends of the two U-shaped retaining frames.

[0006] Two U-shaped sliding frames, positioned by spring pushes, are symmetrically slidably mounted on the two longitudinal mounting plates. Two centering bushings are symmetrically welded to the open ends of the U-shaped sliding frames. A rotating shaft is rotatably mounted on each of the centering bushings. Two ticket-feeding wheels are symmetrically fixed at both ends of the rotating shafts. The ticket-feeding wheels on the four rotating shafts are arranged in pairs, abutting each other, and are used to guide tickets from the ticket outlet of the self-service ticket machine. Two triangular force-bearing blocks are symmetrically welded to the middle position of opposite sides on the longitudinal side plates of the two U-shaped sliding frames. A U-shaped drive frame is slidably mounted on the vertical side rod of one U-shaped retaining frame. A U-shaped pull frame is welded to the vertical side rod of the U-shaped drive frame. Two trapezoidal drive blocks are symmetrically welded to the open ends of the U-shaped drive frame. When the two trapezoidal drive blocks slide toward the two triangular force-bearing blocks, their inclined surfaces abut against each other.

[0007] Furthermore, the trapezoidal drive block is slidably attached to the longitudinal side plate of the longitudinal mounting plate and is located between the longitudinal mounting plate and the longitudinal side plate of the U-shaped sliding frame.

[0008] Furthermore, each of the four rotating shafts has a mounting plate fixed at its head end, and the two rotating shafts near the U-shaped drive frame have mounting plates fixed at their tail ends. A short wheel axle is welded to the center of the outer side of the mounting plate, and a synchronous wheel is fixedly fitted on the short wheel axle.

[0009] An oval-shaped synchronous belt is tensioned between two synchronous pulleys located at the same horizontal level;

[0010] A motor is fixedly installed on the vertical side rod of the U-shaped retaining frame. A drive gear is fixedly mounted on the power output shaft of the motor. The drive gear meshes with two synchronous pulleys on the corresponding side in an up-down orientation.

[0011] Furthermore, two π-shaped mounting brackets are symmetrically welded to the upper and lower ends of the two U-shaped retaining frames.

[0012] Furthermore, two vertical support plates are symmetrically welded to the top of the vertically mounted plate on the bottom side.

[0013] Furthermore, horizontal support plates are welded to the top of the two vertical support plates.

[0014] Furthermore, the top of the horizontal tray and the top of the four ticket-carrying wheels on the lower side are located on the same horizontal reference plane.

[0015] The self-service ticket vending machine ticket dispensing mechanism provided by this utility model has the following beneficial effects:

[0016] 1. Through the guiding principle of two trapezoidal drive blocks and two triangular force-bearing blocks with inclined surfaces, when the U-shaped drive frame slides towards the U-shaped holding frame, it can push and drive the two U-shaped sliding frames to slide in opposite directions, and control the separation of the upper and lower eight ticket conveying wheels. This loosens the tickets clamped between the four front ticket conveying wheels, preventing the clamping pressure between the front ticket conveying wheels and the pulling force of the ticket from opposing forces on the ticket when it is being extracted from the four front ticket conveying wheels, thus avoiding tearing and damaging the ticket. This helps to ensure the integrity of the ticket when it is retrieved.

[0017] Second, through the power transmission of the drive gear, the two synchronous pulleys meshing with the drive gear, and the two oval synchronous belts, the motor can drive the four upper ticket conveying wheels and the four lower ticket conveying wheels to rotate synchronously in opposite directions to roll and transport the tickets. This allows all the ticket conveying wheels to share a single motor for drive, eliminating the need to configure a separate drive unit for each ticket conveying wheel, which helps to simplify the structure of the ticket issuing mechanism and reduce its manufacturing cost.

[0018] Third, the clutchable transmission configuration of the drive gear and the two synchronous pulleys enables the synchronous drive function of the ticket conveying wheel and the release and unlocking function of the ticket conveying wheel to the ticket to be compatible with each other and do not interfere with each other, which helps to ensure the normal and effective implementation of these two functions.

[0040] Please refer to Figures 1 to 5 Example 1:

[0041] This embodiment proposes a ticket dispensing mechanism for a self-service ticket vending machine, including two symmetrically arranged U-shaped retaining frames 1, and two vertically arranged mounting plates 3 are symmetrically welded between the open ends of the two U-shaped retaining frames 1.

[0042] Two U-shaped sliding frames 301, positioned by spring pushes, are symmetrically slidably mounted through two vertically mounted mounting plates 3. Two centering bushings 3011 are symmetrically welded to the open ends of the U-shaped sliding frames 301. A rotating shaft 6 is rotatably mounted through each of the two centering bushings 3011. Two ticket-feeding wheels 601 are symmetrically fixed at both ends of the rotating shaft 6. The four ticket-feeding wheels 601 on the rotating shaft 6 are arranged in pairs, abutting each other, and are used to dispense tickets from the ticket outlet of the self-service ticket machine. The guide output is provided; two triangular force-bearing blocks 2 are symmetrically welded to the middle position of opposite sides of the two U-shaped sliding frames 301 on the vertical side plate; a U-shaped drive frame 9 is slidably installed through the vertical side rod of a U-shaped holding frame 1, a U-shaped pull frame 901 is welded to the vertical side rod of the U-shaped drive frame 9, and two trapezoidal drive blocks 902 are symmetrically welded to the open end of the U-shaped drive frame 9; a rubber ring for increasing the conveying friction is fixedly fitted on the outer periphery of the ticket conveying wheel 601.

[0043] Preferably, the trapezoidal drive block 902 is slidably attached to the longitudinal side plate of the longitudinal mounting plate 3 and is located between the longitudinal mounting plate 3 and the longitudinal side plate of the U-shaped sliding frame 301.

[0044] Implementation 2: This embodiment is based on Implementation 1, but with the following additions:

[0045] Mounting discs 602 are fixed to the beginning of each of the four rotating shafts 6. Mounting discs 602 are fixed to the end of the two rotating shafts 6 near the U-shaped drive frame 9. A short axle 603 is welded to the center of the outer side of the mounting disc 602. A synchronous pulley 604 is fixedly mounted on the short axle 603. An oval synchronous belt 7 is tensioned between the two synchronous pulleys 604 at the same horizontal height. A motor 8 is fixedly mounted on the vertical side rod of one U-shaped retaining frame 1. A drive gear 801 is fixedly mounted on the power output shaft of the motor 8. The drive gear 801 meshes with the two synchronous pulleys 604 on the corresponding side.

[0046] Preferably, two π-shaped mounting brackets 4 are symmetrically welded to the upper and lower ends of the two U-shaped retaining frames 1.

[0047] Preferably, two vertical support plates 501 are symmetrically welded to the top of the bottom longitudinal mounting plate 3.

[0048] Preferably, a horizontal support plate 5 is welded to the top of the two vertical support plates 501.

[0049] Preferably, the top of the horizontal tray 5 and the top of the four ticket delivery wheels 601 on the lower side are located on the same horizontal reference plane.

[0050] The following section provides a detailed explanation of the working principles, specific details, implementation steps, functions and interrelationships of each feature, and their roles in realizing this technical solution:

[0051] Springs mounted on the vertical side bars of the two U-shaped sliding frames 301 can press and abut the eight ticket feeding wheels 601 together. During use, the entire ticket dispensing mechanism is installed and fixed in the ticket dispensing slot of the self-service ticket machine via two π-shaped mounting brackets 4. After the ticket is printed, it is conveyed between the top of the rear part of the horizontal tray 5 and the four rear ticket feeding wheels 601. The four rear ticket feeding wheels 601 continuously convey the ticket forward along the top of the horizontal tray 5 and then convey the ticket to the four front ticket feeding wheels. Between 601, the four front-side ticket conveying wheels 601 relay the forward transport of the ticket. When part of the ticket is conveyed between the four front-side ticket conveying wheels 601, the entire ticket is in a state about to be output from the ticket outlet. The ticket needs to be pulled out from between the four front-side ticket conveying wheels 601 to complete the ticket retrieval operation. At this time, the U-shaped pull frame 901 pulls towards the U-shaped holding frame 1 to drive the U-shaped drive frame 9, thereby driving the two trapezoidal drive blocks 902 to slide towards the two triangular force-bearing blocks 2, and controlling... The inclined surfaces of the four parts abut against each other. Guided by the inclined surfaces of the two trapezoidal drive blocks 902 and the two triangular force-bearing blocks 2, when the U-shaped drive frame 9 slides toward the U-shaped holding frame 1, it can push and drive the two U-shaped sliding frames 301 to slide in opposite directions, and control the separation of the eight upper and lower ticket conveying wheels 601. This releases the tickets clamped between the four front ticket conveying wheels 601, preventing the tickets from being extracted between the four front ticket conveying wheels 601. The clamping pressure and the pulling force of the ticket counteract each other on the ticket, tearing and damaging it, which helps to ensure the integrity of the ticket when it is retrieved; when the two U-shaped sliding frames 301 are driven to slide in opposite directions, the springs on them are compressed. When the triangular force block 2 is slidably driven to separate from the two triangular force blocks 2, the two U-shaped sliding frames 301 lose the pushing and holding force from the U-shaped drive frame 9. The compressed springs can push back to drive the two U-shaped sliding frames 301 to slide away from each other and reset.

[0052] Through the power transmission of the drive gear 801, the two synchronous pulleys 604 meshing with the drive gear 801, and the two oval synchronous belts 7, the motor 8 can drive the four upper ticket conveying wheels 601 and the four lower ticket conveying wheels 601 to rotate synchronously in opposite directions to roll and transport the tickets. This allows all the ticket conveying wheels 601 to share a single motor 8 for driving, eliminating the need to configure a separate drive unit for each ticket conveying wheel 601, which helps to simplify the structure of the ticket issuing mechanism and reduce its manufacturing cost.

[0053] When the two U-shaped sliding frames 301 are driven to slide in opposite directions, the two synchronous pulleys 604 that can drive and mesh with the drive gear 801 will disengage from the drive gear 801. When the two U-shaped sliding frames 301 are driven to reset, the two synchronous pulleys 604 will re-engage with the drive gear 801 and resume synchronous drive, restoring the synchronous drive of the motor 8 to all ticket conveying wheels 601. In this way, the disengageable transmission between the drive gear 801 and the two synchronous pulleys 604 enables the synchronous drive function of the ticket conveying wheel 601 and the release and unlocking function of the ticket conveying wheel 601 to the ticket to be compatible and non-interfering, which helps to ensure the normal and effective implementation of the two functions.
