Or, a second rotating shaft and a third rotating shaft with the axes collinear with the axes of the front paper guide roller 20 are respectively arranged at the two ends of the front paper guide roller 20; a first shaft hole and a second shaft hole are formed on the paper feeding end respectively, and a second rotating shaft and a third rotating shaft are arranged in the first shaft hole and the second shaft hole respectively in a penetrating manner, so that the rotatable connection between the front paper guide roller 20 and the rack 10 is realized.
Specifically, the rotatable connection between the rear paper guide roller 30 and the frame 10 is not limited in this embodiment, and the specific connection manner is the same as that between the front paper guide roller 20 and the frame 10, and is not described again here.
Preferably, the driving device may be any device capable of driving the rear paper guide roller 30 to rotate, and the driving device is not limited in this embodiment; for example: the driving device can comprise a motor, a driven gear with the axis collinear with the axis of the rear paper guide roller 30 is arranged on the rear paper guide roller 30, a driving gear is arranged on a main shaft of the motor, the driving gear is meshed with the driven gear, and the rear paper guide roller 30 can be driven to rotate by the motor; so as to drive the paper tape to move by the friction force between the rear paper guide roller 30 and the paper tape, so that the paper tape has a certain tension in the paper tape transportation device to prevent the paper tape from folding or wrinkling.
Specifically, the paper break detection device 40 may be any device capable of detecting a paper tape break, and sends a paper break signal after detecting the paper tape break, which is not limited in this embodiment; for example: the paper breaking detection device 40 comprises an elastic contact piece, a resisting piece and an alarm, wherein the elastic contact piece and the resisting piece are respectively and electrically connected with the alarm; the elastic contact piece and the abutting piece are respectively arranged on two sides of the paper tape, the elastic contact piece presses the paper tape on the abutting piece under the action of elasticity of the elastic contact piece, when the paper tape is broken, the paper tape between the elastic contact piece and the abutting piece disappears, the elastic contact piece is contacted with the abutting piece, and then the alarm sends out a paper breaking signal. Preferably, the paper breaking signal sent by the alarm can be a light signal and/or a sound signal, so that a worker can find the paper tape breaking in time. In addition, the paper break detection device 40 can also mainly comprise an ultrasonic wave emission device, an echo detection device and an alarm, wherein the ultrasonic wave emission device and the echo detection device are arranged on one side of the paper tape and are arranged at intervals with the paper tape, and the echo detection device is electrically connected with the alarm; when the ultrasonic detection device works normally, the ultrasonic transmitting device transmits ultrasonic waves to the side surface of the paper tape, the ultrasonic waves can generate echoes after encountering the paper tape, and the echo detection device can detect the echoes; when the paper tape is broken, the ultrasonic wave emitted by the ultrasonic wave emitting device cannot contact with the paper tape, so that an echo cannot be generated or the ultrasonic wave meets other objects to enable the time interval of the echo generation to be larger, and the alarm emits a paper breaking signal formed by a light signal and/or a sound signal to prompt staff.
The working process of the paper tape conveying device provided by the embodiment is as follows: after the front end of the paper tape passes through the printer, the paper tape is sequentially wound on the upper part of the front paper guide roller 20 and the upper part of the rear paper guide roller 30, and then the front end of the paper tape is input into the paper cutter; when the printer and the paper cutter work, the paper tape moves from the printer to the paper tape conveying device, the driving device drives the front paper guide roll 20 to rotate, the paper tape between the printer and the paper cutter is further driven to move, and meanwhile, the front paper guide roll 30 rotates to guide the paper tape; the paper tape is moved to the paper cutter after coming out of the paper tape conveying device so as to realize the conveying of the paper tape; when the paper tape breaks, the paper tape between the rear paper guide roller 30 and the paper cutter continues to move towards the paper cutter, so that the paper tape at the rear part of the rear paper guide roller 30 is separated from the paper tape at the front part of the rear paper guide roller 30, the paper break detection device 40 sends out a paper break signal, and a worker can find out that the paper tape breaks in time according to the paper break signal, so that the printer and the paper cutter stop working, and the paper tape is connected together.
In the paper tape transport device provided by the embodiment, the front paper guide roller 20 and the rear paper guide roller 30 are respectively and rotatably arranged at the paper feeding end and the paper discharging end of the rack 10, the driving device is used for driving the rear paper guide roller 30 to rotate, and the paper breaking detection device 40 is arranged at the paper discharging end; and then when the paper tape breaks, the paper break detection device 40 can send out the paper break signal, and the staff can in time discover the paper tape fracture according to the paper break signal, and handle to avoid paper tape pile up, winding.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
