[0001] The utility model relates to the technical field of self-service terminals, in particular to a ticket-issuing anti-pull device and a lottery machine. Background Art

[0002] With the development of society, the profitability disadvantages of brick-and-mortar lottery shops are becoming increasingly apparent, amidst rising rents and labor shortages. As brick-and-mortar stores gradually decline, the rise of self-service lottery ticket machines has led to the widespread adoption of self-service point-of-sale terminals in public places such as convenience stores, shopping malls, gas stations, and train stations. These machines are often unmanned, leaving the purchaser completely independent, leading to numerous operational errors. For example, if a ticket is pulled while the printer is printing, the printer may not cut the ticket, but the ticket may already be damaged, resulting in ticket jams or printer failures. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems in the prior art. To this end, the present invention provides a ticket dispensing anti-pull device that can reduce the probability of machine failure.

The use of "first" or "second" is solely for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of the indicated technical features, or implicitly indicating the order of the indicated technical features.

[0039] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0040] Reference Figures 1 to 4 As shown, the embodiment of the first aspect of the present invention provides a ticket-issuing anti-pull device, which includes: a base frame 100, a paper retaining baffle 200 and a ticket-issuing assembly 300.

[0041] The ticket-issuing anti-pull device can be applied to a variety of tickets, such as lottery tickets, train tickets, and other tickets that need to be printed on the spot. The ticket-issuing anti-pull device has various applications. In this embodiment, the ticket-issuing anti-pull device is applied to the lottery field, and the ticket is a lottery ticket.

[0042] The base frame 100 has a main frame portion 110 with an open slot and a connecting portion 120 covering a portion of the open slot. The portion of the open slot enclosed by the connecting portion 120 and the main frame portion 110 forms a ticket outlet channel 130. The ticket outlet channel 130 is substantially consistent in shape with the ticket. In this embodiment, the ticket is square and the ticket outlet channel 130 is rectangular. The ticket outlet channel 130 is for the ticket to pass through.

[0043] The paper retaining plate 200 is rotatably connected to the base frame 100. Together, the paper retaining plate 200 and the base frame 100 form a temporary storage passage 210 that communicates with the ticket dispensing passage 130. Specifically, the paper retaining plate 200 is rotatably connected to the connecting portion 120 and covers another portion of the open slot. The other portion of the open slot formed by the paper retaining plate 200 and the main frame portion 110 forms the temporary storage passage 210 that communicates with the ticket dispensing passage 130.

[0044] The ticket dispensing assembly 300 is connected to the base frame 100. The ticket dispensing assembly 300 is arranged between the ticket dispensing channel 130 and the temporary storage channel 210, and can connect the temporary storage channel 210 and the ticket dispensing channel 130. The ticket dispensing assembly 300 is used to convey tickets and has a first state and a second state; wherein, the ticket dispensing assembly 300 is configured as follows: when the ticket dispensing assembly 300 is in the first state, when the ticket is in the temporary storage channel 210 and moves toward the ticket dispensing channel 130, the ticket dispensing assembly 300 stops the ticket, the ticket is deformed and drives the paper retaining baffle 200 to rotate in a direction away from the base frame 100 to accommodate the deformed ticket; when the ticket dispensing assembly 300 is in the second state, the ticket dispensing assembly 300 conveys the ticket to the ticket dispensing channel 130, and the paper retaining baffle 200 is reset.

[0045] It is worth noting that before the ticket is printed, one end of the ticket is stopped by the ticket dispensing assembly 300, while the other end continues to print and moves toward the ticket dispensing channel 130, causing the middle part of the ticket to be deformed and arched by stress. The deformation of the ticket causes the paper retaining baffle 200 to deform and increase the space of the temporary storage channel 210, so that the temporary storage space can temporarily accommodate the ticket until the ticket is printed. Then the ticket dispensing assembly 300 outputs the ticket from the ticket dispensing channel 130, completing the ticket dispensing. The ticket is printed and cut within the ticket dispensing anti-pull device. The operation is carried out, and the lottery ticket is output to the ticket dispensing channel 130 only after printing is completed, so that the ticket purchaser cannot pull the lottery ticket being printed. The ticket dispensing anti-pull device can eliminate the problem of machine malfunction caused by pulling. In the process of the ticket dispensing component 300 conveying the ticket to the ticket dispensing channel 130, the paper retaining baffle 200 is in an inclined state, and the inclination angle of the paper retaining baffle 200 automatically adapts to the degree of arch deformation of the ticket, so that the paper retaining baffle 200 can guide the movement of the ticket, improve the stability of ticket conveying, and reduce the ticket dispensing failure rate.

[0046] Reference Figure 4 As shown, in some specific embodiments of the present invention, the paper retaining plate 200 includes a first end portion 220 facing the ticket dispensing channel 130 , and the paper retaining plate 200 is rotatably connected to the base frame 100 at the first end portion 220 .

[0047] It should be noted that the first end portion 220 refers to a three-dimensional portion, which includes not only an end face but also a peripheral surface located at the first end portion 220 .

[0048] It is worth understanding that the second end of the paper retaining baffle 200 relative to the first end 220 is away from the ticket dispensing channel 130. When the second end is away from the base frame 100, the distance between the second end and the bottom surface of the open slot increases, while the distance between the first end 220 and the bottom surface of the open slot remains unchanged, so that a trumpet shape is formed between the paper retaining baffle 200 and the bottom surface of the open slot. The inclined direction of the paper retaining baffle 200 will guide the ticket to move in the direction from the second end to the first end 220. The ticket is guided by the paper retaining baffle 200 and is easier to align with the ticket dispensing component 300, and the ticket dispensing is more stable.

[0049] As some other embodiments, the paper retaining plate 200 further includes a middle portion disposed between the first end portion 220 and the second end portion, and the paper retaining plate 200 is rotatably connected to the frame at the second end portion or the middle portion.

[0050] Reference Figure 2 、 Figure 3 and Figure 4As shown, in some specific embodiments of the present invention, the paper retaining plate 200 includes a main board portion 250 and a limiting portion 230 connected to the main board portion 250. The limiting portion 230 can abut against the base frame 100 to limit the maximum angle of rotation of the main board portion 250 relative to the base frame 100.

[0051] It is worth noting that the limiting portion 230 limits the maximum angle at which the paper retaining baffle 200 can rotate, thereby preventing the limiting portion 230 from excessively rotating and causing the limiting portion 230 to fail.

[0052] In this embodiment, the paper retaining plate 200 can be rotated to be nearly perpendicular to the ground at most, so that when the ticket is reset, the paper retaining plate 200 can rotate toward the base frame 100 under the action of gravity, so that the paper retaining plate 200 can be reset to the initial position.

[0053] As some other embodiments, an elastic reset member can also be provided between the paper retaining baffle 200 and the base frame 100. When the paper retaining baffle 200 is able to rotate in a direction away from the base frame 100 under the stress of the ticket, the elastic reset member is elastically deformed. When the deformation of the ticket is restored, the elastic potential energy of the elastic reset member is released, and the paper retaining baffle 200 is reset.

[0054] Reference Figure 4 As shown, in some specific embodiments of the present invention, the thickness of the temporary storage channel 210 decreases gradually along the direction from the temporary storage channel 210 to the ticket outlet channel 130 .

[0055] The thickness direction of the temporary storage channel 210 corresponds to the thickness direction of the conveyed ticket.

[0056] It is worth understanding that the thickness of the temporary holding channel 210 decreases gradually from the temporary holding channel 210 to the ticket dispensing channel 130 to guide the movement of the ticket within the temporary holding channel 210. The ticket can enter the temporary holding channel 210 more easily, and under the guidance of the temporary holding channel 210, the ticket is aligned with the ticket dispensing channel 130, and can enter the ticket dispensing channel 130 more smoothly, and the ticket dispensing is more stable.

[0057] In this embodiment, the paper retaining plate 200 is tilted, and the distance from the second end to the bottom of the open groove is greater than the distance from the first end 220 to the bottom of the open groove.

[0058] Reference Figure 3 As shown, in some specific embodiments of the present invention, the paper retaining plate 200 includes a first surface facing the temporary storage channel 210 and an abutting portion 240 provided on the first surface, and the abutting portion 240 is used to abut against the ticket.

[0059] It is worth understanding that by abutting the ticket with a separate abutment portion 240, the contact area between the paper retaining baffle 200 and the ticket is reduced, so that the friction between the ticket and the abutment portion 240 is smaller, the ticket is easier to separate from the paper retaining baffle 200, and the ticket output is more stable.

[0060] In this embodiment, the abutting portion 240 includes a plurality of abutting sub-portions arranged at intervals, and the contact area between the ticket and the abutting portion 240 is reduced by the intervals.

[0061] Reference Figure 2 As shown, in some specific embodiments of the present invention, the base frame 100 is provided with a main frame portion 110 and a rotating groove 111 provided on the top of the main frame portion 110, and the paper retaining plate 200 includes a main board portion 250 and a rotating shaft portion 260 connected to the main board portion 250, and the rotating shaft portion 260 is installed in the rotating groove 111 and can rotate relative to the rotating groove 111.

[0062] It is worth noting that the rotating shaft portion 260 is directly placed in the rotating groove 111 to achieve the installation of the paper retaining baffle 200 and the base frame 100. The installation of the paper retaining baffle 200 and the base frame 100 is simple and the disassembly is more convenient.

[0063] In this embodiment, a U-shaped deep groove is provided on the top of the main frame portion 110, namely the rotation groove 111. The outer peripheral surface of the rotation shaft portion 260 is a cylindrical surface, and the rotation shaft portion 260 is directly placed in the rotation groove 111 to realize the rotation of the rotation shaft portion 260.

[0064] Reference Figure 2 and Figure 4 As shown, in some specific embodiments of the present invention, the ticket dispensing assembly 300 includes a first roller member 310, a second roller member 320, a driving member 330 transmission-connected to the first roller member 310, and a rotation-limiting member 340 abutting against the outer circumferential surface of the second roller member 320. The outer circumferential surface of the first roller member 310 is opposite to the outer circumferential surface of the second roller member 320. The first roller member 310 and the second roller member 320 are both rotationally connected to the base frame 100. The rotation-limiting member 340 is used to limit the rotation of the second roller member 320. The ticket dispensing assembly 300 is configured as follows: when the ticket dispensing assembly 300 is in a first state, the driving member 330 stops and limits the rotation of the first roller member 310, and the rotation-limiting member 340 limits the rotation of the second roller member 320; when the ticket dispensing assembly 300 is in a second state, the driving member 330 drives the first roller member 310 to rotate, and the first roller member 310 drives the second roller member 320 to rotate through the ticket.

[0065] It is worth understanding that the first roller 310 and the second roller 320 form a pair of rollers, which convey the ticket to the ticket outlet channel 130. The pair of rollers can improve the stability of the ticket conveying, and the pressure between the first roller 310 and the second roller 320 can fix the ticket, so that when the first roller 310 and the second roller 320 are not rotating, the ticket will not be able to pass between the first roller 310 and the second roller 320. Only when the first roller 310 and the second roller 320 are rotating can the ticket pass between the first roller 310 and the second roller 320.

[0066] In this embodiment, when the driving member 330 does not provide driving force, the first roller member 310 remains stationary and has a certain degree of rotational resistance due to the restriction of the driving member 330. The driving member 330 is a motor. The first roller member 310 and the driving member 330 are connected to each other via a first transmission gear and a second transmission gear. The first transmission gear is located on the output shaft of the motor, and the second transmission gear is located at one end of the first roller member 310. The first transmission gear and the second transmission gear mesh with each other.

[0067] Among them, the main frame 110 is provided with an upper avoidance groove and a lower avoidance groove between the ticket outlet channel 130 and the temporary storage channel 210, and the first roller 310 is arranged at the position of the lower avoidance groove, and part of the first roller 310 is located inside the open groove, and the other part is located outside the open groove; the second roller 320 is arranged at the position of the upper avoidance groove and is limited by the upper avoidance groove along the ticket outlet direction.

[0068] Reference Figure 4 As shown, in some specific embodiments of the present invention, the base 100 has a rotating chamber 140, the second roller 320 is arranged in the rotating chamber 140, and can rotate in the rotating chamber 140; the rotation limiting member 340 includes an elastic member 341, one end of the elastic member 341 abuts against the outer peripheral surface of the second roller 320 away from the first roller 310, and the other end abuts against the base 100; wherein, the second roller 320 is configured as follows: when the ticket issuing assembly 300 is in the first state, the elastic member 341 drives the second roller 320 to contact the first roller When the ticket ejection assembly 300 is in the second state and the ticket is located between the second roller member 320 and the first roller member 310, the elastic member 341 stores elastic potential energy, the second roller member 320 moves away from the first roller member 310, and the first roller member 310 drives the first roller member 310 to rotate through the ticket; when the ticket ejection assembly 300 is in the second state and the ticket escapes from the second roller member 320 and the first roller member 310 and is located in the ticket ejection channel 130, the elastic member 341 is reset, and the outer circumferential surface of the second roller member 320 abuts against the outer circumferential surface of the first roller member 310.

[0069] It is worth noting that the elastic member 341 abuts the side of the second roller member 320 that is away from the first roller member 310. Together with the first roller member 310, the elastic member 341 limits the position of the second roller member 320. Furthermore, when a ticket extends between the first and second roller members 310, the thickness of the ticket pushes the second roller member 320 away from the first roller member 310. The elastic member 341 deforms and stores elastic potential energy, tightly squeezing the first roller member 310, the ticket, and the second roller member 320. Rotating the first roller member 310 drives the second roller member 320, allowing the ticket to smoothly pass through the space between the first and second roller members 310, 320. The second roller member 320 has a simpler structure and can rotate essentially synchronously with the first roller member 310 without the need for additional transmission components, resulting in a lower-cost ticket-dispensing anti-pull device.

[0070] Reference Figure 2 and Figure 4 As shown, in some specific embodiments of the present invention, the rotation-limiting member 340 further includes a rotation-limiting shaft 342, and the elastic member 341 is a torsion spring, which is sleeved around the rotation-limiting shaft 342. It is worth noting that by restricting the outer circumference of the second roller member 320 with the torsion spring, the contact area between the torsion spring and the second roller member 320 is smaller, thereby minimizing the impact on the rotation of the second roller member 320 and ensuring smoother rotation of the second roller member 320. As another embodiment, the elastic member 341 can also be a straight spring.

[0071] The second embodiment of the present invention provides a lottery machine comprising the ticket-dispensing anti-pullout device of the first embodiment. It is worth noting that the lottery machine employing the ticket-dispensing anti-pullout device of the first embodiment can eliminate machine malfunctions caused by pulling, improve the stability of lottery ticket dispensing, and reduce the ticket dispensing failure rate. The remaining structures of the lottery machine are common knowledge to those skilled in the art and will not be elaborated upon here.

[0072] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
