Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, and in particular to a ticket conveying mechanism and a printer. Background Technology

[0002] With the informatization of railway operation management, railway ticket printing equipment has been widely used in railway operation sites such as railway dispatch centers, station operation rooms, locomotive depots, and rolling stock depots. These devices need to print various railway operation tickets at high frequency, such as dispatch orders, train operation certificates, maintenance records, timetable adjustment notices, and safety confirmation slips, which places higher demands on ticket output and management.

[0003] In existing technology, railway ticket printing equipment typically employs a fixed ticket output method. After printing, the printer outputs the ticket directly to a fixed ticket receiving slot or tray at the equipment's exit. When multiple tickets are printed consecutively, they are stacked sequentially at the fixed output position. However, due to the lack of an effective ticket compression and sorting mechanism, tickets are prone to scattering during stacking, affecting the orderly management of tickets.

[0004] Specifically, when a printer outputs multiple railway operation tickets consecutively, the subsequently printed tickets may push or shift the preceding tickets, resulting in uneven stacking. In the railway operating environment, factors such as vibrations from equipment operation, airflow from the air conditioning system, and air disturbances caused by personnel movement all exacerbate the disarray of tickets. This problem is particularly severe during busy periods when a large number of dispatch orders or train operation documents need to be printed.

[0005] Scattered tickets not only affect the efficiency of staff in retrieving tickets, but more importantly, they may lead to omissions or confusion. In railway operations, each ticket has significant guiding significance and legal effect. Scattered tickets may prevent staff from obtaining the necessary operational instructions in a timely and accurate manner, thus affecting the safety and efficiency of train operations. When multiple tickets are scattered and stacked, staff need to sort and check them one by one, which not only increases workload but may also create safety hazards due to omissions during the sorting process.

[0006] Furthermore, scattered tickets are prone to falling off the output point or being blown away, leading to the loss of important operational information. During critical scheduling moments or emergency situations, the loss of tickets can severely impact the continuity and safety of railway operations. Utility Model Content

[0007] This utility model provides a ticket conveying mechanism and a printer. The ticket conveying mechanism effectively solves the technical problem of scattered tickets in the prior art, and realizes the orderly management and convenient use of tickets.

The pressing assembly also includes: a limiting pin, which is connected to the pressing shaft and passes through the strip hole; and a first elastic element, which connects the limiting pin and the bracket. When the pressing shaft rotates, the limiting pin moves with the pressing shaft. Through the cooperation of the strip hole and the first elastic element, the rubber-coated roller contacts and presses the ticket.

[0014] In one possible implementation, a ticket return component is also included, which is mounted on the rack and used to remove tickets from the ticket holder as it moves from the ticket collection position to the ticket receiving position.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0033] The following is combined with Figure 1-9 This utility model describes a ticket conveying mechanism, comprising: a frame 1, a moving unit 2, a ticket holder 3, and a ticket pressing unit 4, wherein: The moving unit 2 is mounted on the frame 1 and has a mounting part 21 that can move along the first direction X. The moving unit 2 is a linear reciprocating moving unit 2, which can drive the mounting part 21 to move back and forth between two points.

[0034] Ticket holder 3 is connected to installation part 21.

[0035] The ticket pressing unit 4 is located in the mounting part 21 and is used to press the tickets on the ticket holder 3.

[0036] The moving unit 2 is used to drive the ticket holder 3 to move between the ticket receiving position and the ticket taking position. The ticket holder 3 located at the ticket receiving position is used to receive the tickets printed by the printer.

[0037] In this invention, the moving unit 2 has a mounting part 21 that can move along a first direction X. The ticket holder 3 is connected to the mounting part 21, allowing the ticket holder 3 to move between the ticket receiving position and the ticket retrieval position under the drive of the moving unit 2. When the ticket holder 3 is in the ticket receiving position, it can accurately receive the tickets printed by the printer; when it moves to the ticket retrieval position, staff can easily retrieve the organized tickets. The ticket pressing unit 4 is located on the mounting part 21 and moves synchronously with the ticket holder 3. During the entire transmission process, it applies pressure to the tickets on the ticket holder 3 to prevent the tickets from becoming scattered due to external interference. The mechanical constraint ensures that the tickets always remain neat and orderly. The design of the moving unit 2 prevents the tickets from being exposed to a fixed position for a long time, reducing the impact of environmental factors on the stability of the tickets; the continuous pressing action of the ticket pressing unit 4 eliminates the displacement and scattering of the tickets caused by gravity, vibration, or airflow; the coordinated operation of the two achieves orderly management of the entire process from ticket receiving to ticket delivery. In railway operations, when multiple dispatch orders or train operation certificates need to be printed consecutively, each ticket can be accurately positioned and neatly stacked with the preceding tickets under the action of the ticket pressing unit 4, avoiding pushing and shifting. The moving unit 2 actively delivers the sorted tickets to a ticket collection position that is easy for staff to operate, ensuring that staff can quickly and accurately obtain all tickets, thereby improving the efficiency and safety of railway operations and solving the problems of low work efficiency and safety hazards caused by scattered tickets in the existing technology.

[0038] In practical operation, the movement of the mounting unit 21 along the first direction X causes the ticket holder 3 to switch positions. When the ticket holder 3 is in the receiving position, it can accurately receive the tickets continuously output by the printer; when it moves to the ticket retrieval position, the user can easily retrieve the tickets without bending over and reaching into the device. The synchronous movement design of the ticket pressing unit 4 ensures that the tickets are effectively pressed and protected in all positions.

[0039] In railway ticket printing applications, when the system prints multiple receipts consecutively, ticket holder 3 first receives each receipt one by one at the receiving position, while the ticket pressing unit 4 ensures that the receipts are neatly stacked. After printing is complete, ticket holder 3 automatically moves to the ticket collection position, allowing customers to collect all receipts at once. The entire process is smooth and efficient.

[0040] Traditional ticket printing methods typically involve a fixed ticket slot or tray at the printer exit, where tickets are stacked directly after printing. This design requires users to be close to the printer to retrieve tickets, and in some installation environments, users may need to bend over or reach into the machine, making operation extremely inconvenient. Even more seriously, tickets exposed to open environments for extended periods are easily scattered by wind or vibration.

[0041] This invention utilizes the active delivery function of the mobile unit 2 to deliver tickets to a location easily accessible to the user, completely transforming the traditional passive ticket retrieval method. The continuous tracking design of the ticket-pressing unit 4 ensures protection of tickets throughout the entire process from receipt to delivery, significantly improving the user-friendliness of the equipment and the reliability of ticket management.

[0042] like Figure 6 As shown, in some embodiments, the ticket holder 3 includes: a connecting frame 31 connected to the mounting part 21; a support frame 32 connected to the connecting frame 31, the top of the support frame 32 is provided with a support part 321 for carrying the ticket, and the end of the support frame 32 facing the printer is provided with an inlet part 322, which is inclined so that the ticket can slide to the support part 321.

[0043] In this invention, the connecting frame 31 is disposed on both sides of the support frame 32, and is responsible for connecting and fixing with the moving unit 2. The support frame 32 is used for carrying and guiding the documents. The division of labor is clear, which facilitates the manufacturing and subsequent maintenance of each component. The inclined arrangement of the guide part 322 on the support frame 32 makes it convenient for the documents falling on the guide part 322 to slide to the support part 321 under the action of their own gravity, thus completing the stacking of the documents.

[0044] Specifically, the connecting frame 31 serves as the interface between the ticket holder 3 and the mounting part 21, and is responsible for motion transmission. The guide part 322 of the support frame 32 faces the printer and is set in an inclined state, forming a transition surface from high to low, along which the ticket can smoothly slide into the support part 321. The support part 321, as the final bearing surface of the ticket, provides a flat and stable placement area.

[0045] In actual use, when the printer outputs a receipt, the receipt first comes into contact with the inclined guide section 322 and slides down the inclined surface towards the support section 321 under the action of gravity. Due to the reasonable design of the inclined angle, the receipt can enter smoothly without generating excessive impact, and each receipt can be accurately positioned at the predetermined position on the support section 321.

[0046] Existing ticket carriers mostly use simple flat plate structures. Tickets are output by the inertial force of the printer and fall directly onto the horizontal surface. During the stacking process, the position of the tickets is prone to instability. When multiple tickets are output continuously, subsequent tickets may push or cover the previous tickets, causing stacking chaos.

[0047] The inclined design of the inlet section 322 of this invention effectively solves these problems. The inclined surface provides a buffer transition for the tickets, reducing the impact and bounce of the tickets; at the same time, the guiding effect of the inclined surface ensures that each ticket can enter the support section 321 according to the predetermined path, realizing the orderly stacking and precise positioning of the tickets.

[0048] like Figure 6 As shown, in some embodiments, a limiting part 323 is provided at the end of the support frame 32 away from the inlet part 322, and the limiting part 323 is used to limit the ticket on the support part 321.

[0049] In this invention, the limiting part 323 forms a closed bearing space for the ticket holder 3, effectively preventing the ticket from accidentally slipping out during reception and movement. The limiting part 323 is located at the end of the support frame 32 away from the guide part 322, forming an opposing relationship with the guide part 322, providing reliable positional constraint for the ticket on the support part 321.

[0050] Specifically, after the ticket enters the support section 321 along the inlet section 322, the limiting section 323 acts as a "baffle" to prevent the ticket from moving forward due to inertia. This design ensures that the ticket can remain stably within a specific area of ​​the support section 321, forming a neat stacking effect. Even if vibration or acceleration changes occur during the movement of the ticket holder 3, the limiting section 323 can prevent the ticket from shifting.

[0051] In high-frequency printing operations, when the printer continuously outputs tickets at a high speed, each ticket carries a certain amount of kinetic energy. The limiting part 323 can effectively absorb this kinetic energy and confine the tickets within a predetermined range. Whether it is a single ticket or the accumulation of multiple tickets, a stable stacking state can be maintained under the constraint of the limiting part 323.

[0052] This invention establishes a complete ticket constraint mechanism through a specially designed limiting part 323. This not only solves the problem of ticket slippage, but more importantly, it achieves precise positioning control of the ticket, creating a stable foundation for subsequent ticket pressing and transmission operations.

[0053] like Figure 7 As shown, in some embodiments, the ticket pressing unit 4 includes: a ticket pressing shaft 41, which is rotatably disposed on the mounting part 21 and located above the ticket holder 3; a ticket pressing assembly 42, which is disposed on the ticket pressing shaft 41 and is used to press the ticket on the ticket holder 3; and a drive assembly 43, which is disposed on the mounting part 21 and whose output end is connected to the ticket pressing shaft 41 and is used to drive the ticket pressing shaft 41 to rotate.

[0054] In this invention, the pressing unit 4 achieves precise control over the pressing process of the tickets through the coordinated operation of the pressing shaft 41, the pressing assembly 42, and the drive assembly 43. Precise management of the pressing timing and pressure is achieved through active control. The pressing unit 4 is mounted entirely on the mounting part 21, ensuring its synchronous movement with the ticket holder 3.

[0055] Specifically, the drive component 43 includes a ticket pressing motor and a transmission belt. The ticket pressing motor drives the ticket pressing shaft 41 to rotate through the transmission belt. The ticket pressing shaft 41 drives the ticket pressing component 42, which presses the stacked tickets.

[0056] In practical applications, when the ticket needs to be pressed, the control system activates the drive component 43, the pressing shaft 41 rotates in a predetermined direction, and the pressing component 42 descends and contacts the ticket; when the ticket needs to be released for the user to retrieve, the drive component 43 reverses its operation, and the pressing component 42 rises and moves away from the ticket. The entire process can be precisely controlled according to actual needs.

[0057] In some embodiments, the ticket pressing assembly 42 includes: a bracket 421, one end of which is connected to the ticket pressing shaft 41; and a rubber-coated roller 422, which is rotatably disposed at the end of the bracket 421 away from the ticket pressing shaft 41.

[0058] In this invention, the ticket pressing component 42 employs a bracket 421 in conjunction with a rubber-coated roller 422, achieving a balance between structural compactness and functional practicality. The bracket 421 acts as a connecting bridge, reliably connecting the rubber-coated roller 422 to the ticket pressing shaft 41. The rubber-coated roller 422, as the working component in direct contact with the ticket, has undergone specialized optimization in both material properties and structural form. Specifically, one end of the bracket 421 is fixedly connected to the ticket pressing shaft 41, while the other end provides an installation position for the rubber-coated roller 422. The rubber-coated roller 422 can rotate around its own axis; this design reduces frictional resistance between the roller and the ticket while ensuring effective pressing contact. The selection of the rubber coating material fully considers the contact characteristics with the ticket, requiring sufficient friction to prevent slippage while also possessing appropriate softness to avoid damage.

[0059] During the ticket pressing process, the performance of the rubber-coated roller 422 directly affects the overall result. When the rubber-coated roller 422 presses down and contacts the ticket, the rubber-coated surface can form a good fit with the ticket. Even if there are slight unevenness or thickness differences on the ticket surface, the deformation capacity of the rubber material can ensure maximum contact area. The rotation function of the roller prevents shearing force from being generated while contacting the ticket, thus protecting the integrity of the ticket.

[0060] This invention utilizes a rubber-coated roller 422. The elastic deformation capability of the rubber coating allows it to adapt to stacks of documents of different thicknesses, ensuring a uniform distribution of clamping force. The soft contact characteristics protect the surface of the documents from damage. The roller's rotation design further reduces mechanical stress on the documents, achieving a perfect balance between effective clamping and document protection.

[0061] like Figure 7 As shown, in some embodiments, the bracket 421 and the pressing shaft 41 are rotatably connected by a bearing 423. The bracket 421 is provided with a strip hole 4211. The pressing assembly 42 further includes: a limiting pin 424, which is connected to the pressing shaft 41 and passes through the strip hole 4211; and a first elastic element 425, which connects the limiting pin 424 and the bracket 421. When the pressing shaft 41 rotates, the limiting pin 424 moves with the pressing shaft 41. Through the cooperation of the strip hole 4211 and the first elastic element 425, the rubber-coated roller 422 contacts and presses the ticket.

[0062] In this utility model, the bearing 423 connection design between the bracket 421 and the pressing shaft 41, together with the precise cooperation of the strip hole 4211, the limiting pin 424 and the first elastic element 425, constructs a staged pressing control system, realizing a gradual process from light contact to stable pressing, avoiding the impact of instantaneous pressing on the ticket, and at the same time having the adaptive adjustment capability of pressing force.

[0063] Specifically, the bearing 423 connection eliminates the sliding friction between the bracket 421 and the pressing shaft 41, improving transmission efficiency and system lifespan. The slotted hole 4211 provides limited movement space for the limiting pin 424. When the pressing shaft 41 begins to rotate, the limiting pin 424 moves within the slotted hole 4211. Initially, the rubber-coated roller 422 naturally descends under gravity to contact the ticket; at this stage, the pressure is low, only for positioning. As the pressing shaft 41 continues to rotate, the limiting pin 424 moves to a position separating from the bottom of the slotted hole 4211. At this point, the first elastic element 425 begins to function. The compression of the elastic element generates a downward elastic force, which is transmitted to the rubber-coated roller 422 through the bracket 421, achieving formal pressing of the ticket. This two-stage pressing process ensures both effective pressing and avoids damage to the ticket caused by sudden pressing.

[0064] In practical applications, this design demonstrates good adaptability. When the number of tickets is small, the compression of the first elastic element 425 is small, resulting in a relatively light clamping force; when the tickets are stacked thickly, the compression of the elastic element increases, providing a greater clamping force, ensuring that the tickets achieve a suitable clamping effect under different conditions.

[0065] This invention employs a progressive clamping process to protect the integrity of the document, while adaptive pressure adjustment ensures the stability of the clamping effect. This not only improves the reliability of the equipment but also expands its applicability to different types of documents.

[0066] In some embodiments, a ticket return component 5 is also included, which is disposed on the rack 1 and is used to remove tickets from the ticket holder 3 when the ticket holder 3 moves from the ticket collection position to the ticket receiving position.

[0067] In this invention, the ticket return component 5 is responsible for removing any remaining tickets from the ticket holder 3, ensuring that the ticket holder 3 is clean before receiving new tickets each time. The ticket return component 5 is fixedly installed on the rack 1, and the ticket clearing action is automatically triggered by the movement of the ticket holder 3, realizing an unattended automatic maintenance function.

[0068] Specifically, after completing a work cycle, ticket holder 3 may have residual tickets on its surface for various reasons. These residual tickets include valid tickets that users did not completely remove, invalid tickets detected by the system as having quality problems, or blank tickets generated due to printing errors. If these tickets are not removed in a timely manner, they will be mixed with the new tickets printed next time, causing chaos in ticket management.

[0069] Among them, the ticket refund component 5 selects to perform the ticket clearing action during the process of the ticket holder 3 returning from the ticket collection position to the ticket receiving position. At this time, only the tickets that need to be cleared are usually left on the ticket holder 3, avoiding the mistaken clearing of valid tickets. The return movement of the ticket holder 3 is used as a power source, eliminating the need for an additional drive device and simplifying the system structure.

[0070] In continuous operation scenarios, the value of the ticket return component 5 becomes even more apparent. For example, in a bank's self-service equipment, if a customer forgets to take a receipt, the receipt will be automatically cleared when the ticket holder 3 returns, preventing confusion with the next customer's ticket. This automatic clearing function greatly reduces the frequency of equipment maintenance and improves system reliability.

[0071] This utility model automates and systematizes ticket clearing by setting up a dedicated ticket return component 5. This not only eliminates the need for manual clearing but also ensures the timeliness and thoroughness of the clearing action, providing a reliable guarantee for the stable operation of the ticket delivery system.

[0072] like Figure 3 , 4As shown in Figure 8, in some embodiments, the ticket return assembly 5 includes: a ticket return shaft 51, rotatably mounted on the frame 1; a ticket return piece 52, connected to the ticket return shaft 51, the ticket return piece 52 having a driving part 521 and an intercepting part 522, the ticket return piece 52 having a first state and a second state, when the ticket return piece 52 is in the first state, the intercepting part 522 is located at the bottom of the ticket holder 3, when the ticket return piece 52 is in the second state, the intercepting part 522 is higher than the height of the support part 321 of the ticket holder 3, used to intercept the ticket on the ticket holder 3; a second elastic member 53, one end of the second elastic member 53 is connected to the ticket return piece 52, and the other end is connected to the frame 1, so that the ticket return piece 52 is kept in the first state; wherein, the driving part 521 is used to abut against the ticket holder 3, so that the ticket return piece 52 flips.

[0073] In this invention, the ticket refund unit 52 can switch between a first state and a second state. Combining the working principles of mechanical triggering and elastic reset, an automatic ticket clearing mechanism is constructed. The state transition of the ticket refund unit 52 relies entirely on mechanical action, requiring no electric drive or complex control, which ensures the reliability of the function while reducing the complexity and cost of the system.

[0074] Specifically, the two states of the return ticket holder 52 have clear functional divisions. The first state is the default state of the return ticket holder 52, in which the limiting part 323 is at the bottom of the ticket holder 3, which does not affect the normal operation of the ticket holder 3 or the processing of tickets. The second state is the working state of the return ticket holder 52, in which the limiting part 323 rises to a position sufficient to intercept tickets, effectively clearing all tickets from the surface of the ticket holder 3. When the ticket holder 3 moves, its base plate 33 partially contacts the driving part 521 of the return ticket holder 52, and the pushing force causes the return ticket holder 52 to rotate around the return ticket axis 51, switching from the first state to the second state. The second elastic element 53 is stretched and stores energy throughout the process. When the ticket holder 3 passes and loses its pushing force, the second elastic element 53 releases energy, driving the return ticket holder 52 back to the first state, completing a complete working cycle.

[0075] The ticket refund component 5 of this invention adopts a purely mechanical working method. Regardless of changes in ambient temperature or the duration of equipment operation, the mechanical triggering mechanism maintains stable operating characteristics. Furthermore, since it does not rely on electric drive, the ticket refund function can still operate normally even if there are problems with the equipment's power system.

[0076] In some embodiments, the ticket holder 3 further includes a base plate 33, which is connected to the connecting frame 31 and located below the support frame 32. The base plate 33 is used to abut against the driving part 521 during movement.

[0077] In this invention, the base plate 33 provides a dedicated trigger interface for the ticket refund component 5, ensuring the accuracy and consistency of the triggering action. As an integral part of the ticket holder 3, the position and size of the base plate 33 have been precisely calculated to ensure reliable triggering of the ticket refund component 5 while avoiding interference with other functions of the ticket holder 3.

[0078] Specifically, the base plate 33 is connected to the connecting frame 31 and located below the support frame 32. This arrangement makes the base plate 33 the leading component when the ticket holder 3 moves. The length of the base plate 33 along the first direction X is greater than the length of the support plate along the first direction X, so that when the ticket holder 3 moves back and forth between the ticket receiving position and the ticket taking position, the base plate 33 is always the first to contact the ticket return component 52. When the ticket holder 3 approaches the ticket return assembly 5, the base plate 33 first contacts the driving part 521, effectively transferring the kinetic energy of the ticket holder 3 to the ticket return component 52. The presence of the base plate 33 also plays a protective role, avoiding direct collision between the main functional components such as the support frame 32 and the ticket return assembly 5.

[0079] Without a dedicated triggering mechanism, the ticket return component 5 can only rely on contact with the main structure of the ticket holder 3 to trigger, which poses multiple risks. First, the uncertainty of the contact surface may lead to unstable triggering force, affecting the reliability of the ticket return component 52's operation; second, improper contact may cause wear or damage to the main functional components of the ticket holder 3; finally, the lack of a specially designed contact surface may lead to inaccurate triggering timing, affecting the ticket clearing effect.

[0080] In some embodiments, the moving unit 2 includes: a ticket feeding motor 22; a transmission assembly connecting the ticket feeding motor 22 and the mounting part 21, for transmitting power from the ticket feeding motor 22 to the mounting part 21; and a guide assembly 23 for guiding the mounting part 21 to move.

[0081] In this invention, the moving unit 2 employs a complete scheme combining a motor drive with a transmission and guiding system, achieving high-precision control of the ticket holder 3's movement. The motor's rotational motion is converted into linear motion through the transmission component, and then the guiding component 23 ensures the accuracy of the motion trajectory. The coordinated operation of these three components guarantees the accuracy and repeatability of the ticket holder 3's movement.

[0082] Specifically, the ticket delivery motor 22, as the power source, can achieve precise speed and angle control. Modern motor control technology can control the angle accuracy within a very small range, which provides a foundation for the precise positioning of the ticket holder 3. The transmission assembly converts this precise rotational control into linear movement control, maintaining the transmission of control precision. The guide assembly 23 ensures that this precise movement always follows a predetermined straight trajectory. The three components have clear functional divisions and cooperate with each other. The ticket delivery motor 22 focuses on providing stable and controllable power, and its speed and direction can be precisely adjusted as needed. The transmission assembly undertakes the task of motion form conversion and power transmission, converting rotational motion into linear motion while also adjusting speed and torque through the transmission ratio. The guide assembly 23 is specifically responsible for constraining the motion trajectory, ensuring that the mounting part 21 can only move along the first direction X without deviation.

[0083] In practical applications, this design delivers excellent positioning accuracy and smooth movement. The ticket holder 3 can accurately move to the preset ticket receiving and retrieval positions with high positional repeatability and a smooth, vibration-free movement. This precision is crucial for ticket processing, as any positional deviation can affect ticket reception or the user's ticket retrieval experience.

[0084] In some embodiments, the transmission assembly includes: a synchronous pulley 24 rotatably mounted on the frame 1; a drive wheel 25 disposed at the output end of the ticket feeding motor 22; a synchronous belt 26 sleeved on the synchronous pulley 24 and the drive wheel 25, and the synchronous belt 26 connected to the mounting part 21; and a guide assembly 23 including an optical shaft disposed on the frame 1 and extending along a first direction X, and the mounting part 21 slidably disposed on the optical shaft.

[0085] In this invention, the combination of the synchronous belt 26 transmission system and the optical shaft guide structure constructs a high-precision linear motion mechanism. The synchronous belt 26 transmission ensures the accurate conversion from rotary motion to linear motion, while the optical shaft guide provides high-quality linear motion constraints. The cooperation between the two achieves high precision and high stability in the movement of the ticket holder 3.

[0086] Specifically, the synchronous belt 26 drive has unique advantages. Compared with chain drives, the synchronous belt 26 has no hinge gap, resulting in higher transmission accuracy; compared with rack and pinion drives, the synchronous belt 26 runs more smoothly and with lower noise; compared with wire rope drives, the synchronous belt 26 has less elastic deformation and better positioning accuracy. The tooth profile design of the synchronous pulley 24 and drive pulley 25 ensures precise meshing between the synchronous belt 26 and the pulley, avoiding slippage. The design of the optical shaft guiding system also considers the requirements of accuracy and stability. The surface of the optical shaft is precision machined, possessing high straightness and surface finish, providing an ideal sliding surface for the mounting part 21. The sliding fit of the mounting part 21 on the optical shaft is precisely designed to ensure smooth movement while avoiding wobbling caused by excessive clearance.

[0087] This utility model provides a printer, including the aforementioned document conveying mechanism.

[0088] In this invention, the integrated design of the ticket conveying mechanism and the printer realizes an integrated solution for the ticket processing process. This not only simplifies equipment configuration but also optimizes the entire process from ticket generation to delivery, providing users with a more complete and convenient ticket processing experience.

[0089] Specifically, the printer is responsible for generating and printing the ticket content, while the ticket conveying mechanism is responsible for receiving, sorting, pressing, and transmitting the tickets. The physical integration of the two functional modules eliminates uncertainties in intermediate links. Tickets go directly into the conveying mechanism after being output from the printer, avoiding interference from external factors. It also facilitates coordinated control between the two systems, enabling precise coordination between printing and conveying.

[0090] Integrated design also demonstrates significant advantages in space utilization. Compared to separate printing and conveying equipment, integrated equipment occupies less space and has a more compact layout. This is of great significance for space-constrained applications, such as bank branches and hospital counters, where saving equipment space translates to more customer service space.

[0091] From a user experience perspective, integrated equipment provides a one-stop ticket processing service. Users only need to interact with one device to complete all operations from ticket application to ticket acquisition, with a unified interface and simplified workflow. The integrated design of the equipment also improves reliability and reduces potential failure points caused by multiple devices working together.
