[0022] In order to more clearly and completely illustrate the technical scheme of the utility model, the utility model will be further described below in combination with the drawings.

[0023] Please refer to Figures 1-4 The utility model provides a device of real time detection printing paper roll diameter, including printer support platform 1, printer support platform 1 is provided with two paper roll turntables 2, the top center of paper roll turntable 2 is provided with transmission shaft 3, the outside fixed of transmission shaft 3 located at the right side is provided with paper roll body 4, including positioning rod 5 and sensor 6, the bottom of positioning rod 5 is fixedly connected with the top of printer support platform 1, positioning rod 5 is fixedly installed with protective shell 7 on the outside through bolt, sensor 6 is movably clamped in protective shell 7, and sensor 6 is used to detect the distance between it and paper roll body 4.

[0024] It should be noted that the distance between the sensor 6 and the paper roll is measured, thereby obtaining the thickness of the paper roll, and further analyzing the use of the paper roll body 4, accurately grasping the remaining amount of the current paper roll body 4, which is more accurate than the traditional method based on the counter (such as the number of printed pages or length), because the actual length of the paper used may vary due to different printing tasks; and in some cases, if the thickness of the paper roll body 4 changes abnormally (such as too fast thinning, which may indicate paper slipping or incorrect paper feeding), the sensor 6 can detect these problems in time, helping users to discover and solve potential mechanical failures or operation errors as soon as possible.

[0025] In the embodiment, the sensor 6 includes an infrared range finder, which is used to non-contact detect the diameter change of the paper roll body. One side of the protective shell 7 is provided with an opening, and the other side of the protective shell 7 is provided with two reserved holes 8, which are matched with the infrared range finder. The protective shell 7 provides a certain degree of physical protection for the sensor 6, preventing damage caused by accidental collision or direct contact, reducing the influence of external electromagnetic interference on the sensor 6 to a certain extent, ensuring the accuracy of data transmission, and facilitating accurate fixing of the position of the sensor 6 to ensure that it is always in the best working position. The main function of the reserved hole 8 is to allow the infrared range finder to interact with the paper roll body 4 through necessary optical signals.

[0026] In the embodiment, one end of the paper roll body 4 is fixedly connected to the outside of the transmission shaft 3 located at the right side, and a plurality of guides 12 are rotatably installed on the top of the printer support platform 1, and the guides 12 are in transmission connection with the paper roll body 4.

[0027] In this embodiment, the outer side of the positioning rod 5 is provided with a sheet plate 9, one side of the sheet plate 9 is in sliding connection with the paper roll body 4.

[0028] In this embodiment, one side of the sheet plate 9 is provided with a flange structure, one side of the flange structure is provided with a sliding surface, which is used to reduce the wear of the paper roll body 4 caused by friction during transmission, and to ensure that the paper roll body 4 can slide smoothly.

[0029] It should be noted that the sheet plate 9 is in surface contact with the paper roll body 4, which increases the friction and prevents the paper roll body 4 from sliding or jumping during unwinding or winding, and reduces the label position deviation or other printing quality problems caused by inconsistent speed; when the paper roll body 4 is subjected to external impact or internal tension change, the sheet plate 9 can play a certain buffering role, absorbing part of the vibration and impact energy, maintaining the stability of the paper roll body 4 transmission, and the sheet plate 9 has a certain elasticity and is in surface contact with the paper roll body 4, increasing the angle of guidance and increasing the stroke of the paper roll body 4 to the printing mechanism; when the paper roll body 4 is too heavy due to its large diameter, the paper roll body 4 will be pressed down by the sheet plate due to insufficient power when starting to feed the paper, increasing the paper feeding amount and ensuring the printing quality.

[0030] Further description is that the sheet plate 9 reduces the lateral movement or deviation of the paper roll body 4 during transmission, so that the sensor 6 can more accurately measure the distance between the sensor 6 and the paper roll body 4.

[0031] In this embodiment, the top rear side of the printer support platform 1 is fixedly connected with an extension plate 10, the top of the extension plate 10 is provided with a printing mechanism 11, and the paper roll body 4 penetrates through the printing mechanism 11.

[0032] It should be noted that the paper sticking mechanism is used to realize the accurate peeling of the paper layer (label) from the bottom paper layer and accurately stick it to the target object, and the paper sticking mechanism mainly includes a paper peeling plate, a guide device and a control system. The paper peeling plate usually has a sharp angle or edge, which helps to peel the paper from the bottom paper, and the control system controls the speed and direction of the motor, etc., to ensure that the whole paper sticking process is smooth and efficient, and can receive the data of the sensor 6, and automatically control the motor to stop working when the paper roll body 4 is used up.

[0033] In this embodiment, the paper roll body 4 includes a plurality of paper layers on a bottom paper layer, and the plurality of paper layers are arranged closely on one side of the bottom paper layer. The paper layer is a label, and the bottom paper layer serves to support and protect the paper layer. The paper layer can be attached to the bottom paper layer by means of adhesive, hot melt or other appropriate means, allowing the paper layer to be peeled off from the bottom paper layer when needed and applied to the surface of a predetermined object.

[0034] The working principle of the utility model is as follows: when the printing operation starts, the paper roll body 4 starts from the transmission shaft 3 on the right, information printing is carried out through the printing mechanism in the printer, the paper layer (label) is automatically peeled off at the printing mechanism 11 and is attached to the surface of the predetermined object, such as a reagent bottle, and the base paper layer continues to move until it reaches the transmission shaft 3 on the left, so as to facilitate the recycling of the paper roll body 4 and complete the whole cycle.

[0035] Of course, the utility model can also have other various implementation manners, and other implementation manners obtained by the ordinary skilled person in the art based on the present implementation manner without any creative labor all belong to the range protected by the utility model.
