[0031] With reference to Figures 1-5 The paper feeding assembly comprises two groups of first rubber rollers 12, each group having two first rubber rollers 12, one end of each first rubber roller 12 being rotatably connected to the inner wall of the body 1, one end of each first rubber roller 12 being fixedly connected with a gear 13, every two gears 13 being engaged, two second motors 14 being arranged inside the body 1, one end of each second motor 14 being fixedly connected with one end of the corresponding first rubber roller 12, one end of one of the first rubber rollers 12 being provided with a first synchronous wheel 15, a second rubber roller 16 being arranged inside the body 1, the second rubber roller 16 being located below the print head 3, the structure of the second rubber roller 16 being adapted to the structure of the print head 3, a second synchronous wheel 17 being arranged on one side of the second rubber roller 16, the first synchronous wheel 15 and the second synchronous wheel 17 being driven by a belt.

[0032] The paper feeding assembly can ensure the stability of paper feeding. Specifically, the two paper feeding openings 2 on the left and right sides are respectively an entry opening and an exit opening. When a printing task needs to be performed, the two second motors 14 are started, one of the second motors 14 drives the first rubber roller 12 connected thereto to rotate. Since every two gears 13 are engaged, the two first rubber rollers 12 in the same group can rotate in opposite directions synchronously. The paper passes between the two first rubber rollers 12. Under the friction of the rubber rollers, the paper is smoothly conveyed forward. At the same time, the second synchronous wheel 17 connected to the first synchronous wheel 15 on one of the first rubber rollers 12 by the belt drive drives the second rubber roller 16 to rotate. The second rubber roller 16 is adapted to the structure of the print head 3 and can better cooperate with the work of the print head 3, further ensuring that the paper remains flat and stable when passing below the print head 3, so that the paper feeding speed is uniform and the direction is accurate during printing, effectively preventing problems such as paper jamming and skewing, thereby ensuring that the printed content can be accurately and correctly printed on the paper, improving the printing quality and efficiency.

[0033] The paper feeding assembly ensures the accurate transmission of the paper during the entire printing process, greatly reduces the probability of problems such as paper jamming, paper skewing, and poor paper feeding, thereby effectively reducing the printing interruption and paper waste caused by paper feeding failure, improving the continuity and efficiency of the printing operation, and the accurate and uniform paper feeding speed and stable paper posture are highly adapted to the working height of the print head 3, so that the printed content can be clearly, accurately and neatly presented on the paper, effectively ensuring the printing quality, and the clarity of the text and the integrity of the image can be excellently presented, meeting various printing needs, providing users with a smoother, more efficient and high-quality printing experience, and improving the overall performance and practicality of the inkless printing device.

[0034] With reference toFigure 1 and Figure 2 The outer wall of the body 1 is provided with a plurality of buttons 18, and the outer wall of the body 1 close to the second motor 14 is provided with a plurality of heat dissipation holes 19.

[0035] The plurality of buttons 18 provide a convenient way for the user to operate the printer, and the user can easily realize various function operations such as printing, pausing, paper feeding and withdrawing, cleaning the print head 3, and turning on and off the power supply through the buttons 18, without complex operation process or the aid of other external devices, greatly improving the convenience and efficiency of the user using the printer.

[0036] The heat dissipation holes 19 help the heat generated during the operation of the motor to be dissipated in time, maintain the normal working temperature of the motor, prevent the performance of the motor from being reduced, the service life from being shortened, and even the motor from being damaged due to overheating, so as to ensure the stable and reliable operation of the paper feeding assembly.

[0037] Working principle: when starting a printing task, the paper enters from the paper feeding opening 2 of the body 1, and the two second motors 14 are started. One of the second motors 14 drives the first rubber roller 12 connected thereto to rotate, and the two first rubber rollers 12 in the same group are synchronously and reversely rotated through the meshing of the gears 13, and the paper is stably fed forward by the friction force of the rubber rollers. At the same time, through the belt transmission of the first and second synchronous wheels 15 and 17, the second rubber roller 16 is driven to rotate, and cooperates with the print head 3 to ensure that the paper is kept flat and stable when passing under the print head 3, so that the printing content is accurately printed on the paper at a precise paper feeding speed and direction, and the paper is sent out from the paper feeding opening 2 on the other side after printing.

[0038] During printing, the heat dissipation holes 19 on the outer wall of the body 1 close to the second motor 14 will dissipate the heat generated during the operation of the motor in time, maintain the normal working temperature of the motor, and ensure the stable operation of the paper feeding assembly.

[0039] When the print head 3 needs to be cleaned after a long time of use, the user presses the button 18 on the outer wall of the body 1 to drive one of the first motors 6 to rotate the print head 3 by 90 degrees towards the cleaning roller 4, and the soft brush 7 on the surface of the cleaning roller 4 is contacted. Then, the other first motor 6 is started to drive the cleaning roller 4 to rotate, and the dust, paper scraps and other impurities on the surface of the print head 3 are cleaned down. The impurities fall into the contact plate 8 under the action of gravity, and the contact plate 8 is stably collected in position through the sliding connection of the sliding block 11 and the sliding groove 10 of the fixed plate 9. When the impurities are collected to a certain extent, the user can pull out the end of the contact plate 8 outside the body 1 to clean it, maintain the cleanliness of the print head 3, ensure the printing quality and stable operation of the device, meet the diversified printing needs of the user, and improve the use experience and work efficiency.

[0040] The above merely describes preferred embodiments of the present application, and is not intended to limit the technical scope of the present application in any way. Any minor modification, equivalent change, and modification made according to the technical essence of the present application to the above embodiments still falls within the technical scope of the present application.
