Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of sticker output devices, and more specifically to a sticker machine that can prevent paper from being ejected along with the sticker. Background Technology
[0002] Currently, sticker dispensers are widely used in areas such as children's learning rewards, stationery dispensing, and interactive entertainment. They primarily use a motor-driven roller to rotate the sticker roll, dispensing stickers one by one for users to take. These devices typically employ a dual-roller or single-roller structure, using friction to transport the stickers and achieve the rolling and dispensing of the stickers. However, due to their relatively simple overall structure, the sticker roll is easily affected by external forces during dispensing, resulting in poor paper dispensing stability and difficulty in maintaining precise paper length for each use. Furthermore, existing products generally lack effective limiting and anti-reverse mechanisms, which can easily cause multiple stickers to slide out simultaneously when the stickers are pulled, affecting the user experience and wasting resources.
[0003] Existing sticker printing machines still have many shortcomings in their power transmission and sticker control structures. On the one hand, some products use single-sided roller drive, resulting in insufficient meshing between the rollers and slippage during sticker transmission, causing uneven paper output. On the other hand, the paper cutting components have a simple design, mostly with flat or smooth edges, failing to effectively limit the sticker edges and thus failing to provide anti-slip and anti-reverse functions. In addition, existing sticker printing machines have complex structures for sticker roll installation and replacement, with most brackets being fixed. Users need to disassemble machine parts when changing stickers, which is inconvenient and affects daily operating efficiency.
[0004] Therefore, there is an urgent need to provide a sticker machine with a compact structure, high paper output accuracy, and the ability to prevent stickers from slipping out. Through a reasonable roller transmission structure and sawtooth limit design, it can achieve smooth sticker output and effective backlash prevention, and has a convenient sticker roll replacement structure, thereby improving the reliability and practicality of the device. Utility Model Content
[0005] The present invention aims to provide a sticker machine that can prevent paper from being ejected along with the sticker, in order to solve the technical problems of unstable sticker output, inconsistent paper length, and stickers easily slipping out when subjected to force in existing sticker machines.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A sticker printer that prevents paper from being ejected along with the paper, characterized in that it includes an upper cover, a bottom shell, a machine body, and a bottom cover, wherein the machine body is provided with a sticker roll, a bracket, a battery, a first roller, a second roller, a motor assembly, a central control panel, an infrared detection assembly, and a charging module.
[0008] The sticker is wound around the outside of the rotating drum of the bracket, and the surface of the sticker roll is provided with identification points;
[0009] The bracket is rotatably connected to the rotating drum. A conveying roller is provided on the outer periphery of the first roller, and a locking gear is provided on the outer periphery of the second roller, which is used to cooperate with the edge of the sticker roll to form a limiting clamp.
[0010] The motor assembly outputs power to the first roller via a reducer. The first roller is fixed with a drive gear, which meshes with a driven gear on the second roller to drive the sticker output.
[0011] The infrared detection component is positioned above or below the sticker output path to detect identification points on the sticker surface and output control signals to the central control panel. The central control panel controls the motor component to start and stop according to the detection signals, thereby realizing single-sheet output control.
[0012] The front end of the machine body is provided with a paper cutter. The leading edge of the paper cutter is provided with serrations. The serrations engage with the edge of the sticker to prevent the sticker from being pulled out when it is not driven.
[0013] Preferably, the central control panel includes a Bluetooth communication module and a control logic module, used to receive trigger signals sent by an external reading pen or learning terminal to start sticker output.
[0014] Preferably, the infrared detection component includes an infrared emitter and an infrared receiver. The infrared emitter is used to illuminate the surface of the sticker, and the infrared receiver is used to identify the reflected signal of the identification point.
[0015] Preferably, the bracket is installed inside the machine body, and the rotating drum is detachably rotatably connected to the bracket via a rotating shaft, making it convenient for the user to remove or replace the sticker roll.
[0016] Preferably, the paper cutter is fixed at the paper outlet of the machine body, and the serrations are inclined toward the sticker roll side so as to generate reverse resistance on the sticker when the user tears it off, preventing the sticker from being output along with it.
[0017] Preferably, the battery is disposed in the lower space of the body and electrically connected to the charging module to provide power to the central control panel and motor assembly.
[0018] Preferably, the top cover can be flipped open relative to the bottom shell for loading, unloading, and maintenance of the sticker roll.
[0019] Preferably, the central control panel is equipped with control buttons and a switch, and the user can control the start and stop via the control buttons.
[0020] Preferably, the saw teeth are integrally formed wavy structures or equidistant saw teeth structures, and the material is metal or hard plastic, which is used to enhance the anti-slip and cutting effect.
[0021] Compared with existing technologies, this utility model has significant improvements in overall structure and performance. Through the coordinated transmission of the first and second rollers, the sticker roll maintains stable operation during output, preventing sticker offset or slippage and ensuring paper output accuracy. The paper cutter at the front of the machine has a serrated structure; when the sticker output stops, the serrations and the sticker edge form a mechanical limit, effectively preventing the sticker from being continuously pulled out under external force, thus achieving an anti-slip effect. The motor assembly outputs power to the first roller via a reducer, and through the engagement of the drive gear and the driven gear on the second roller, achieves smooth and efficient power transmission, making the paper output smoother. The bracket and the rotating drum adopt a detachable rotating connection structure, facilitating quick removal or replacement of the sticker roll by the user, improving maintenance and operation convenience. The infrared detection component achieves accurate detection by identifying the identification points on the sticker surface, ensuring consistent paper length each time and more reliable output control. The internal structure adopts a layered arrangement, with the battery located in the lower space, the motor assembly in the middle, and the sticker roll in the upper part, resulting in a compact overall structure, reasonable center of gravity, and easy assembly. The central control panel integrates a Bluetooth communication module and a control logic module, enabling signal interaction with external devices. The overall control system layout is clear and the connection is reliable. The top cover can be flipped open, and the bottom shell and the bottom cover form a closed space, effectively preventing dust and foreign objects from entering the internal mechanism, further improving the safety and service life of the entire machine.

Detailed Implementation
[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Example
[0031] like Figures 1 to 5 As shown, this utility model provides a sticker dispenser with anti-spreading paper function. Its overall structure consists of an upper cover 1, a bottom shell 101, a body 102, and a bottom cover 103. The body 102 has a hollow cavity inside, used to install key components such as the sticker roll 4, bracket 5, battery 6, first roller 8, second roller 7, motor assembly 9, central control panel 10, infrared detection assembly 11, and charging module 12. The arrangement of each component is optimized to achieve efficient paper dispensing control and anti-spreading function within a limited space.
[0032] The sticker roll 4 has a roll-like structure, composed of a sticker layer and a release paper layer wound together. Identification points 401 are provided on its surface for position identification during paper output. The sticker roll 4 is fixed inside the machine body 102 by a bracket 5. A rotating drum 501 is mounted on the bracket 5 and is rotatably connected to the bracket 5 via a rotating shaft, allowing it to rotate synchronously with the output of the sticker roll. The bracket 5 has a detachable structure, enabling quick loading and unloading of the sticker roll without disassembling the machine body. Users only need to open the top cover 1 to complete the replacement operation, greatly improving ease of use.
[0033] The first roller 8 and the second roller 7 are arranged parallel to each other on both sides of the sticker output path to clamp the sticker and provide transmission power. A conveying roller 801 is provided on the outer periphery of the first roller 8, generating a frictional driving force with the sticker layer. A locking gear 702 is provided on the outer periphery of the second roller 7. Together, they apply a clamping force to the edge of the sticker roll, thus forming a limiting clamping structure that keeps the sticker stable during output, preventing slippage or displacement. The motor assembly 9 outputs power to the first roller 8 through a reducer 901. A driving gear 802 is fixed on the first roller 8, and the driving gear 802 meshes with the driven gear 701 on the second roller 7 to achieve synchronous rotation between the two rollers. This power transmission path structure is simple, tightly meshed, and highly efficient, ensuring the stability and consistency of the sticker during transport.
[0034] The infrared detection component 11 is positioned above or below the sticker output path, including an infrared transmitter and receiver. It identifies the identification point 401 on the sticker surface and sends a signal to the central control panel 10 to control the start and stop of the motor component 9. The central control panel 10 is located on the outer surface of the device and integrates control buttons 201 and a switch 2 for manual start and stop operations. Its internal circuitry includes a Bluetooth communication module and a control logic module, enabling signal interaction with external reading pens or smart devices for automated control. Through the cooperation of infrared detection and the central control panel, the output of stickers can automatically stop after reaching the length of one sheet, effectively avoiding the problem of continuous output of multiple stickers.
[0035] A paper cutter 3 is located at the front of the machine body and is fixed at the paper outlet. Its leading edge has serrations 301, which are evenly distributed along the sticker output direction. After the sticker is output to its designated position, the edge of the sticker makes slight contact with the serrations 301, forming a physical fit. This provides both limiting resistance and allows for single-sheet cutting when the user gently pulls. The wavy shape of the serrations 301 also helps to prevent the sticker from retracting after paper output stops, preventing paper from being pulled out along with the sticker due to external force. This ensures that the sticker machine maintains a stable sticker position even when stationary.
[0036] The motor assembly 9 is mounted on the inner wall of the bottom shell 101 and fixed with screws. Its output shaft is connected to the reducer 901, and the reducer 901 housing is fixed inside the body 102 by a mounting bracket. The entire transmission system is in a closed space, preventing the entry of external dust or foreign objects and improving the stability and durability of the mechanical transmission. The battery 6 is installed in the lower space of the body 102 and connected to the charging module 12, providing independent power to the central control panel 10 and the motor assembly 9.
[0037] The top cover 1 is connected to the bottom shell 101 via a hinge and can be rotated open along the rear end for easy installation, replacement, or maintenance of the sticker roll. The inner side of the top cover 1 has a limiting structure that ensures a tight fit with the bottom shell 101 when closed, guaranteeing a sealed machine and preventing foreign objects from entering. The bottom shell 101 and the bottom cover 103 are connected by threads or snaps to form a fully enclosed outer shell structure, resulting in a neat appearance and robust structure for the sticker machine.
[0038] During operation, the user can start the device via control button 201, or trigger the central control panel 10 to operate the motor assembly 9 by sending a Bluetooth signal from an external reading pen. The motor drives the first roller 8 to rotate via reducer 901, and through the engagement of the driving gear 802 with the driven gear 701 on the second roller 7, the two rollers work together to output the sticker. The sticker roll moves forward along the paper output path under the clamping action of the rollers. After the infrared detection component 11 identifies the identification point 401 on the sticker surface, the central control panel 10 receives the signal and controls the motor to stop. The output stops after the sticker is exposed to an appropriate length. At this time, the serrations 301 slightly engage with the edge of the sticker, and the user can gently pull along the direction of the serrations to peel off the sticker.
[0039] The structure of this invention ensures precise control over sticker output, maintaining constant tension on the sticker roll and preventing issues such as offset, jamming, or slippage. The roller and gear transmission are stable and reliable, the paper cutter and sawtooth design effectively improve anti-backflow performance, the detachable connection between the bracket and the drum facilitates maintenance, and the infrared detection ensures consistent paper length. The overall device is compact, simple to manufacture, and safe and reliable to operate, making it suitable for mass production and application in children's learning reward devices, smart toys, and office stationery.
