Description

Technical Field

[0001] This utility model relates to ticket processing equipment, and more particularly to a lottery ticket winding device. Background Technology

[0002] For small-format tickets like lottery tickets, slitting is required after the entire sheet is printed. This involves winding the printed sheet into a semi-finished product, then slitting it according to the number of tickets printed along its axis to create tickets of the corresponding size. The slitted tickets then need to be wound and cut to the required length to obtain the final product. Current lottery ticket slitting typically utilizes a high-speed cutting machine in conjunction with a winding device. Specifically, the tickets are placed in a feeding rack, and the winding device's traction causes the entire sheet of tickets to move at high speed, while the high-speed cutting machine cuts the tickets into the required sizes.

[0003] Because the semi-finished product after winding is relatively heavy, and because paper is brittle, simply using the winding equipment to pull the paper can easily cause it to break due to excessive stretching at the beginning of the production process. To avoid this problem, the current practice in the field is to reduce the weight of the semi-finished product by shortening the winding length. However, this leads to frequent roll changes during the production process, resulting in a decrease in continuous production efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a lottery ticket winding device that reduces the risk of paper breakage while improving production efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A lottery ticket winding device includes a feeding mechanism, a feeding shaft, and an auxiliary lifting mechanism; The feeding shaft is connected to the feeding mechanism via a transmission. The auxiliary lifting mechanism is located on the feeding side of the feeding shaft; The auxiliary lifting mechanism has a lifting arm, which is located below the feeding shaft in the vertical direction and is used to press against the semi-finished material.

[0006] Furthermore, the feeding mechanism includes a feeding drive and an output gear; The feeding drive is connected to the output gear, and the output gear is connected to the input end of the feeding shaft.

[0007] Furthermore, the feeding shaft includes an expansion shaft, an input gear, and a locking assembly; The expansion shaft is coaxially arranged with the input gear, and the input gear meshes with the output gear; The expansion shaft and the input gear are at least partially mounted on the housing of the lottery winding device; The locking assembly is located between the expansion shaft and the input gear, and the locking assembly is hinged to the housing of the lottery winding device.

[0008] Furthermore, the locking assembly includes a latch and a fastener; One end of the latch is hinged to the housing, and the other end of the latch is detachably connected to the housing via the fastener; The latch has an arc-shaped limiting portion between its two ends that matches a portion of the expansion shaft. When the latch is connected to the housing via the fastener, the arc-shaped limiting portion presses against the expansion shaft.

[0009] Furthermore, the auxiliary lifting mechanism includes a support shaft, at least two lifting arms, and at least two lifting drive components; One end of the lifting arm is hinged to the housing of the lottery winding device via the support shaft, the lifting drive is hinged to the lifting arm, and the end of the lifting arm away from the support shaft is located below the feeding shaft.

[0010] Furthermore, the end of the lifting arm away from the support shaft has a guide slope; In the direction away from the support axis of the lifting arm, the guide ramp gradually sinks in the direction away from the feeding axis.

[0011] Furthermore, the end of the lifting arm away from the support shaft has a limiting hook.

[0012] Furthermore, the lifting arm is hinged to the support shaft via a connector.

[0013] Furthermore, the lottery ticket winding device also includes a guiding mechanism; A counter is provided on the guide mechanism, and the sensing end of the counter is disposed opposite to the surface of the guide mechanism; The bottom of the guide mechanism is equipped with a lighting component; In the vertical direction, the projection area of ​​the counter is located within the illumination range of the lighting component.

[0014] Furthermore, the counter is connected to the housing of the lottery winding device via a support member, and the counter is tilted.

[0015] The beneficial effects of this utility model are as follows: by setting up a feeding mechanism and a feeding shaft, a driving force is provided to the rolled semi-finished product, which avoids the semi-finished product from breaking due to excessive paper stretching during the unwinding process. An auxiliary lifting mechanism is also set up, which supports the rolled semi-finished product, reduces the pressure on the feeding shaft, maximizes the weight of the rolled semi-finished product, thereby reducing the roll change frequency and improving production efficiency.

[0018] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0019] Please refer to Figure 1 as well as Figure 2 A lottery ticket winding device includes a feeding mechanism 1, a feeding shaft 2, and an auxiliary lifting mechanism 3; the feeding shaft 2 is connected to the feeding mechanism 1 in a transmission manner; the auxiliary lifting mechanism 3 is located on the feeding side of the feeding shaft 2; the auxiliary lifting mechanism 3 has a lifting arm 31, which is located below the feeding shaft 2 in the vertical direction, and the lifting arm 31 is used to press against the semi-finished material.

[0020] Understandably, by setting up the feeding mechanism 1 and the feeding shaft 2, the driving force is provided to the rolled semi-finished product, preventing the semi-finished product from breaking due to excessive paper stretching during the unwinding process. An auxiliary lifting mechanism 3 is also set up. At the same time, the setting of the auxiliary lifting mechanism 3 provides support for the rolled semi-finished product, reduces the pressure on the feeding shaft 2, maximizes the weight of the rolled semi-finished product, thereby reducing the roll change frequency and improving production efficiency.

[0021] In some embodiments, the feeding mechanism 1 includes a feeding roller 11, a feeding drive, and an output gear; the feeding drive is driven by the output gear, and the output gear is driven by the input end of the feeding shaft 2. Preferably, the feeding drive is a servo motor.

[0022] In some embodiments, the feeding shaft 2 includes an expansion shaft 21, an input gear 22, and a locking assembly 23. The expansion shaft 21 and the input gear 22 are coaxially arranged, and the input gear 22 meshes with an output gear. The expansion shaft 21 and the input gear 22 are at least partially mounted on the housing 4 of the lottery ticket winding device. The locking assembly 23 is located between the expansion shaft 21 and the input gear 22, and is hinged to the housing 4 of the lottery ticket winding device. The expansion shaft 21 allows for quick assembly and disassembly of the semi-finished product roll, and the meshing of the expansion shaft 21 with the input gear 22 and the output gear enables rapid replacement of the semi-finished product. The locking assembly 23 is provided to improve the stability and reliability of the expansion shaft 21 during rotation.

[0023] In some embodiments, the locking assembly 23 includes a latch 231 and a fastener 232; one end of the latch 231 is hinged to the housing 4, and the other end of the latch 231 is detachably connected to the housing 4 via the fastener 232; the latch 231 has an arc-shaped limiting portion between its two ends that matches a portion of the expansion shaft 21, and when the latch 231 is connected to the housing 4 via the fastener 232, the arc-shaped limiting portion abuts against the expansion shaft 21. Through the cooperation of the fastener 232 and the latch 231, the connection and release of the expansion shaft 21 and the housing 4 are achieved, ensuring the connection stability between the input gear 22 and the output gear.

[0024] In some embodiments, the auxiliary lifting mechanism 3 includes a support shaft 32, at least two lifting arms 31, and at least two lifting drive members 33. One end of each lifting arm 31 is hinged to the housing 4 of the lottery winding device via the support shaft 32. The lifting drive members 33 are hinged to the lifting arms 31, and the end of the lifting arm 31 away from the support shaft 32 is located below the feeding shaft 2. The lifting height of the lifting arms 31 can be controlled by the lifting drive members 33 to adapt to the continuously shrinking radius during the unwinding process of the semi-finished product, thereby always providing support for the semi-finished product.

[0025] In some embodiments, the lifting arm 31 has a guide slope 312 at the end away from the support shaft 32; the guide slope 312 gradually descends in the direction away from the feeding shaft 2 in the direction away from the lifting arm 31 away from the support shaft 32. The guide slope 312 is provided to guide and support the paper during the unwinding process.

[0026] In some embodiments, the end of the lifting arm 31 away from the support shaft 32 has a limiting hook 311. The limiting hook is set to play a positioning role between the semi-finished roll and the lifting arm 31, thereby improving the positioning accuracy.

[0027] In some embodiments, the lifting arm 31 is hinged to the support shaft 32 via a connector 34 to extend the lifting arm 31, and the lifting arm 31 with the corresponding structure can be quickly replaced according to the actual situation, making it highly versatile.

[0028] In some embodiments, the lottery ticket winding device further includes a guide mechanism 5; a counter 6 is disposed on the guide mechanism 5, with the sensing end of the counter 6 positioned opposite to the surface of the guide mechanism 5; an illumination component 7 is disposed at the bottom of the guide mechanism 5; in the vertical direction, the projection area of ​​the counter 6 is located within the illumination range of the illumination component 7. The counter 6 is used to identify the counting blocks on the lottery ticket, thereby calculating the number of lottery tickets that have passed through the counter 6, and calculating the unwinding length based on the number of lottery tickets, thus enabling timely control of the winding length of the lottery tickets with higher accuracy.

[0029] In some embodiments, the counter 6 is connected to the housing 4 of the lottery winding device via a support member, and the counter 6 is tilted.

[0030] The working principle of this utility model is as follows: Through the cooperation of feeding mechanism 1 and feeding shaft 2, the semi-finished product located on feeding shaft 2 is unwound, while the other end of the semi-finished product is pulled by traction mechanism. During the unwinding process of the semi-finished product, the lifting arm 31 of the auxiliary lifting mechanism 3 is always pressed against the bottom of the semi-finished product roll, and as the radius of the semi-finished product roll gradually decreases, the lifting drive component 33 controls the lifting arm 31 to continuously lift.
