Technical Field
[0001] This utility model relates to the field of service robot technology, and in particular to a ticket output guide structure for a passenger service robot with a printer. Background Technology
[0002] The intelligent robot features a humanoid design with a head and body, and its overall appearance is predominantly white, giving it a sophisticated and natural look. Its internal structure is rationally designed, including a maintenance compartment for easy upkeep. It also employs a dual-screen design, comprising an advertising screen and an operation screen, with the overall height around 1.5 meters and the operation screen mounted on the front. The robot is equipped with wheels for easy movement and fixation, but it lacks printer connectivity, failing to meet passengers' needs for ticket printing. Therefore, a robot with an integrated printer has emerged in the market, offering a simpler structure, easier assembly, higher stability, and lower cost. However, in existing robots with printers, the ticket output guiding structure often relies on guide rollers within the ticket outlet, consisting of an outer roller and an inner roller. Since the outer and inner rollers are often connected by a nested joint, long-term rotation under stress can cause the gap between them to widen, leading to loosening of the outer roller. This affects the stability and reliability of ticket output, reducing the robot's service quality and increasing maintenance costs. Utility Model Content
[0003] The technical problem this invention aims to solve is that in the existing technology, after long-term rotation under stress, the gap between the two components tends to increase, which can lead to loosening of the outer roller, affecting the stability and reliability of ticket output, thereby reducing the service quality of the robot and increasing maintenance costs. To address this, we propose a ticket output guide structure for a passenger service robot with a printer.
[0004] To achieve the above objectives, this application adopts the following technical solution: a ticket output guide structure for a passenger service robot with a printer, comprising a printing body installed on the outer wall of the robot body, a ticket output guide assembly provided at the outlet of the printing body, the ticket output guide assembly comprising a mounting frame disposed inside the printing body, a ticket output port communicating with the outlet of the printing body being opened on one side of the mounting frame, a guide outer roller being disposed on the inner wall of the ticket output port, and a guide reinforcement inner roller assembly being installed on the inner wall of the guide outer roller.
[0005] Furthermore, the guide and reinforced inner roller assembly includes an inner roller body rotatably connected to the inner wall of the ticket output port. A control block is rotatably connected to one end of the inner roller body. The control block penetrates the outer wall of the inner roller body. A first screw is fixedly connected to the end through which the control block penetrates. A second screw is fixedly connected to the end of the first screw away from the control block. A first slider is threadedly connected to the outer wall of the first screw. A second slider is threadedly connected to the outer wall of the second screw. A first push rod and a second push rod are respectively axially connected to the opposite sides of the first and second sliders. An outer support block is axially connected to the opposite ends of the first and second push rods. The outer support block is always in contact with the inner wall of the guide outer roller, realizing active support and adjustment of the guide outer roller by the outer support block. It can compensate in real time according to the change of the fit gap between the two, and always maintain a tight nested connection relationship.
[0006] Furthermore, the first screw and the second screw have opposite thread structures, and both the first screw and the second screw are rotatably connected to the inner wall of the inner roller body. When the control block rotates in one direction, the first screw will drive the first slider to move closer to the second slider, and the second screw will drive the second slider to move closer to the first slider. That is, the two sliders move closer to each other synchronously. When the control block rotates in the opposite direction, the two sliders move away from each other synchronously.
[0007] Furthermore, both the first and second sliders are slidably connected to the inner wall of the inner roller body, eliminating ineffective shaking during the transmission process, improving the response accuracy of the adjustment mechanism, and ensuring that the outer support block can quickly and accurately compensate for the gap between the inner and outer rollers.
[0008] Furthermore, a reinforcing block is fixedly connected to the outer wall of one end of the outer support block that is in contact with the guide outer roller. The interior of the reinforcing block is hollowed out, and multiple sets of elastic blocks are fixedly connected inside the reinforcing block, which further strengthens the connection stability between the inner roller and the outer roller.
[0009] Furthermore, both the reinforcing block and the elastic block are components made of rubber. Through the elastic deformation of the rubber material, the microscopic gap between the outer support block and the inner wall of the guide roller can be filled, thus buffering the vibration and impact generated during the document transportation process.
[0010] The technical effects and advantages of this utility model are as follows:
[0011] In this invention, when a gap develops between the guide outer roller and the inner roller body due to long-term use, the operator rotates a control block at one end of the inner roller body. The control block drives the coaxially fixed first and second screws to rotate synchronously. Since the threads of the two screws are opposite and are threadedly connected to the first and second sliders respectively, the rotational force is converted into the linear motion of the sliders. The two sliders move closer to each other along the slide rail on the inner wall of the inner roller body, pushing the first and second push rods connected to the shaft to swing outward, thereby pushing the outer support block to slide outward along the opening on the outer wall of the inner roller body until the outer support block is tightly fitted against the inner wall of the guide outer roller, compensating for the gap. This solves the problem that since the outer roller and inner roller are mostly connected by a sleeve, the gap between them tends to increase after long-term rotation under force, leading to loosening of the outer roller, affecting the stability and reliability of ticket output, thus reducing the service quality of the robot and increasing maintenance costs.

[0018] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0019] Reference Figures 1-4 As shown, to address the issue that the outer and inner rollers are mostly connected by a socket joint, and that long-term rotation under stress can easily increase the clearance between them, leading to loosening of the outer roller, affecting the stability and reliability of ticket output, and consequently reducing the service quality of the robot and increasing maintenance costs, the following preferred technical solution is provided:
[0020] A ticket output guiding structure for a passenger service robot with a printer includes a printing body 2 mounted on the outer wall of the robot body 1. The printing body 2 is the core component for ticket printing, responsible for printing information onto the ticket. A ticket output guiding component 3 is located at the outlet of the printing body 2, which performs the functions of ticket transport and guidance, ensuring accurate and stable ticket output. A mounting frame 31 of the guiding component 3 is fixedly installed inside the printing body 2, providing stable support for the entire guiding structure. A ticket output port 32 is located on one side of the mounting frame 31 and connects to the outlet of the printing body 2, forming a ticket output channel. A guide outer roller 33 is installed on the inner wall of the ticket output port 32. The guide outer roller 33 directly contacts the ticket, playing a transporting and guiding role during ticket output. The inner wall of the guide outer roller 33 and a guide reinforcement inner roller assembly 34 form a nested connection. The guide reinforcement inner roller assembly 34 actively adjusts the supporting force on the guide outer roller 33 to eliminate the gap between them and prevent the guide outer roller 33 from loosening.
[0021] The inner roller assembly 34, which is guided and reinforced, and the outer roller 33, together form a core mating structure. The operation and coordination of their components are precise and orderly. The inner roller body 341 is rotatably connected to the inner wall of the ticket output port 32, serving as the supporting foundation for the entire inner roller assembly. It rotates synchronously with the outer roller 33. A control block 342 is rotatably connected to one end of the inner roller body 341, penetrating the outer wall of the inner roller body 341. Operators can adjust the inner roller assembly by rotating the control block 342. A first screw 343 is fixedly connected to one end of the control block 342, and a second screw 344 is fixedly connected to the end of the first screw 343 away from the control block 342, forming a "control block-double screw" transmission connection. When the control block 342 rotates, it drives the first screw 343 and the second screw 344 to rotate synchronously. The outer wall of the first screw 343 is threadedly connected to the first slider 345, and the outer wall of the second screw 344 is threadedly connected to the second slider 346. The opposite sides of the first slider 345 and the second slider 346 are respectively connected to the first push rod 347 and the second push rod 348 via shafts. The opposite ends of the first push rod 347 and the second push rod 348 are connected to the outer support block 349 via a shaft. The outer support block 349 is slidably connected to the outer wall opening of the inner roller body 341, allowing it to move inward and outward along the opening direction. The outer support block 349 always fits against the inner wall of the guide outer roller 33, forming a complete force transmission chain of "screw-slider-push rod-outer support block". When the operator rotates the control block 342, the first screw 343 and the second screw 344 rotate synchronously. Due to their threaded connection with the slider, they drive the first slider 345 and the second slider 346 to move relative to each other. The movement of the sliders pushes the first push rod 347 and the second push rod 348 to swing, which in turn pushes the outer support block 349 to slide along the opening on the outer wall of the inner roller body 341, thereby adjusting the support force on the inner wall of the guide outer roller 33. Through the rigid connection and transmission between multiple components, the outer support block 349 actively supports and adjusts the guide outer roller 33. It can compensate in real time according to the change in the fit gap between the two, always maintaining a tight nested connection, fundamentally solving the problem of outer roller loosening, ensuring the stable rotation of the guide outer roller 33 when the ticket is output, and ensuring that the ticket can be output smoothly.
[0022] The first screw 343 and the second screw 344 have opposite thread structures, and both are rotatably connected to the inner wall of the inner roller body 341. This opposite thread structure is a key design feature for achieving relative motion between the two sliders. When the control block 342 rotates in one direction, the first screw 343 drives the first slider 345 to move closer to the second slider 346, while the second screw 344 drives the second slider 346 to move closer to the first slider 345; that is, the two sliders move closer together synchronously. When the control block 342 rotates in the opposite direction, the two sliders move further apart synchronously. Simultaneously, the rotatable connection between the first screw 343 and the second screw 344 and the inner wall of the inner roller body 341 provides a stable fulcrum for the entire transmission structure, ensuring that power can be efficiently transmitted from the control block 342 to the sliders. This ensures that the opening action of the outer support block 349 is uniform and symmetrical, avoids uneven wear or local gaps in the guide roller 33 due to uneven force, effectively maintains the coaxiality of the inner roller and the outer roller, extends the service life of the guide roller 33, ensures the straightness of the document conveying, and enables the document to be accurately output to the designated position.
[0023] Both the first slider 345 and the second slider 346 are slidably connected to the inner wall of the inner roller body 341. This sliding connection restricts the direction of movement of the sliders, eliminating their rotational freedom and allowing them to move only in a straight line along the axial direction of the inner roller body 341. This precisely converts the rotational motion of the first screw 343 and the second screw 344 into the translational motion of the first slider 345 and the second slider 346. This, in turn, stably pushes the outer support block 349 via the first push rod 347 and the second push rod 348, eliminating ineffective wobbling during transmission, improving the response accuracy of the adjustment mechanism, ensuring that the outer support block 349 can quickly and accurately compensate for the gap between the inner and outer rollers, maintaining a stable fit between them, and guaranteeing the reliability of the support adjustment.
[0024] A reinforcing block 3410 is fixedly connected to the outer wall of one end of the outer support block 349 that is in contact with the guide outer roller 33. The interior of the reinforcing block 3410 is hollow, and multiple sets of elastic blocks 3411 are fixedly connected inside the reinforcing block 3410. The reinforcing block 3410 is fixedly connected to the outer support block 349 and moves with the outer support block 349. The elastic blocks 3411 are embedded inside the reinforcing block 3410, forming a composite connection structure of "rigid support + flexible buffer". When the outer support block 349 pushes the reinforcing block 3410 to fit against the inner wall of the guide outer roller 33, the elastic blocks 3411 will undergo elastic deformation due to compression. This deformation allows the reinforcing block 3410 to fit more tightly against the inner wall of the guide outer roller 33. The elastic deformation of the rubber material can fill the microscopic gap between the outer support block 349 and the inner wall of the guide outer roller 33, buffer the vibration and impact generated during the document transportation process, avoid repeated changes in the fit clearance caused by rigid contact, further strengthen the connection stability between the inner roller and the outer roller, and make the rotation of the guide outer roller 33 more stable.
[0025] Both the reinforcing block 3410 and the elastic block 3411 are made of rubber. Rubber's excellent elasticity ensures that the elastic block 3411 maintains good resilience under continuous compression, thus maintaining the preload on the inner wall of the guide roller 33. Simultaneously, the rubber surface has appropriate frictional properties, enhancing the static friction between the reinforcing block 3410 and the inner wall of the guide roller 33, preventing relative slippage that could affect transmission. Furthermore, the rubber material has good wear resistance, allowing it to withstand long-term, high-frequency contact rotation and extending the service life of the connection structure. This improves the durability of the fit between the reinforcing block 3410 and the inner wall of the guide roller 33, reduces the decrease in support force due to material wear, and lowers the frictional noise generated during relative rotation of the inner and outer rollers, maintaining the quiet operation of the robot and enhancing the user experience.
[0026] Specifically, after the printing body 2 completes the printing of the ticket, the ticket enters the ticket output port 32 of the ticket output guide assembly 3 through the outlet. The mounting frame 31 provides rigid support for the entire guide structure, ensuring the stability of the ticket output path. The guide outer roller 33 on the inner wall of the ticket output port 32 directly contacts the ticket and achieves conveying through rotation. Its inner wall forms a nested fit with the guide reinforcement inner roller assembly 34—the inner roller body 341 serves as the core support component, with both ends rotatably connected to the inner wall of the ticket output port 32, and can rotate synchronously with the guide outer roller 33, avoiding relative friction that aggravates wear.
[0027] When a gap develops between the guide outer roller 33 and the inner roller body 341 due to long-term use, the operator rotates the control block 342 at one end of the inner roller body 341. The control block 342 drives the coaxially fixed first screw 343 and second screw 344 to rotate synchronously. Since the two screws have opposite thread directions and are threadedly connected to the first slider 345 and the second slider 346 respectively, the rotational force is converted into the linear motion of the sliders: the two sliders move closer to each other along the slide rail on the inner wall of the inner roller body 341, pushing the first push rod 347 and the second push rod 348 connected to the shaft to swing outward, thereby pushing the outer support block 349 to slide outward along the opening on the outer wall of the inner roller body 341 until the outer support block 349 is tightly attached to the inner wall of the guide outer roller 33, compensating for the gap. This solves the problem that since the outer roller and inner roller are mostly connected by a socket, after long-term rotation under force, the gap between the two is easy to increase, which leads to the outer roller being prone to loosening, affecting the stability and reliability of ticket output, thus reducing the service quality of the robot and increasing maintenance costs.
[0028] The reinforcing block 3410 at the end of the outer support block 349 moves synchronously with it. The rubber reinforcing block 3410 and the internal elastic block 3411 are compressed and undergo elastic deformation, which not only fills the microscopic gaps between the outer support block and the inner wall of the outer roller, but also forms a continuous pre-tightening force through elasticity, buffering the vibration and impact during ticket transportation and preventing the gap from recurring. At the same time, the sliding connection between the first slider 345 and the second slider 346 restricts the degree of rotational freedom and ensures efficient power transmission; the reverse thread screw design ensures that the outer support block is subjected to uniform force and maintains the coaxiality of the inner and outer rollers.
[0029] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
