Along the extending direction of the first conveying channel 116, the detecting part 118 is arranged on one side of the peeling shaft 113 far away from the printing head 111, and the detecting part 118 is used for detecting the existence state of the peeled label 211, when the detecting part 118 detects that the peeled label 211 exists, the printing head 111 stops printing, when the label 211 printed in this way is not taken away, the printing head 111 does not perform the next printing operation, the following printing is realized, namely, one label 211 is printed, and the next label 211 is printed after the label 211 is taken away, the problem that the plurality of labels 211 are difficult to correspond to corresponding goods after being printed simultaneously is avoided, so that the delivery efficiency is improved, and the using effect is better.

The label peeling printing structure 100 provided in the present embodiment is further explained as follows:

referring to fig. 1, in this embodiment, the label 211 printing structure further includes a printing rubber roller 112, the printing rubber roller 112 and the peeling shaft 113 are disposed along the first conveying path 116, and the printing head 111 and the printing rubber roller 112 are disposed at an interval, so that when the label 211 in the first conveying track moves between the printing head 111 and the printing rubber roller 112, the label 211 can be printed by the printing head 111.

Specifically, the peeling shaft 113 and the printing roller 112 are both cylindrical members with circular cross sections, the printing roller 112 and the peeling shaft 113 are disposed along the extending direction of the first conveying passage 116, the backing paper 212 in the first conveying passage 116 moves along the extending direction of the first conveying passage 116, as shown in fig. 1, the extending direction of the first conveying passage 116 is the direction from right to left, i.e., the peeling shaft 113 is located at the left side of the printing roller 112. The print head 111 is disposed right above the print roller 112, and the print head 111 and the print roller 112 are respectively located on both sides of the first conveyance path 116.

Specifically, the peeling roller 114 is a cylindrical member having a circular cross section, the peeling roller 114 is located at the lower left of the printing roller 112, and the second conveyance path 117 extends from the peeling shaft 113 to the direction in which the gap between the peeling roller 114 and the printing roller 112 extends. Because the first transport path 116 and the second transport path 117 are at an acute angle, as the liner 212 is diverted around the peel axis 113 along the first transport path 116 into the second transport path 117, the label 211 is disengaged from the liner 212 and continues to move along the first transport path 116.

The interleaving paper 212 is wound around the recovery shaft 115, and the rotation of the recovery shaft 115 drives the interleaving paper 212 to smoothly move along the first conveying path 116 and the second conveying path 117, and the interleaving paper is recovered on the recovery shaft 115, in other words, the first conveying path 116 and the second conveying path 117 are connected to form a motion track of the interleaving paper 212.

The detecting member 118 is disposed at the front side of the first conveying path 116, that is, the detecting member 118 is located at the left side of the first conveying path 116, the label 211 moves along the first conveying path 116 to the peeling shaft 113, and after being peeled from the backing paper 212, the backing paper 212 continues to move in the extending direction of the first conveying path 116 to move to the detecting member 118, and the presence of the peeled label 211 is detected. Specifically, the detecting member 118 is a sensor, and when the sensor is shielded, the voltage of the sensor is at a low level, which indicates that the peeled label 211 is present; when the sensor is not blocked, the voltage of the sensor is high, which indicates that the peeled label 211 is not present, and the print head 111 can print the next label 211.

Further, the label peeling printing structure 100 further comprises an indicator light electrically connected to the detecting member 118, and the indicator light is used for displaying an optical signal characterizing the detecting structure of the detecting member 118. Specifically, the label peeling printing structure 100 further includes a controller, the detecting member 118, the indicator light, and the print head 111 are electrically connected to the controller, and the controller controls the indicator light and the print head 111 according to the presence state of the peeled label 211 detected by the detecting member 118.

According to the label peeling and printing structure 100 provided by the embodiment, the working principle of the label peeling and printing structure 100 is as follows:

before printing, the detecting member 118 detects the existence of the peeled label 211, and when the label 211 exists at the detecting member 118, the controller controls the indicator lamp to blink, and at this time, the print job can be continuously issued, but the print head 111 does not print. When no label 211 exists at the detecting part 118, the controller controls the indicator light to be normally on, the printing head 111 performs a printing job according to a printing task, and during the printing process, if the label 211 exists at the detecting part 118, the controller controls the printing head 111 to pause printing until the detecting part 118 detects that the label 211 does not exist.

The label peeling printing structure 100 provided by the embodiment has at least the following advantages:

the label peeling printing structure 100 provided by this embodiment detects the existence state of the peeled label 211 by setting the detecting element 118, and controls the printing head 111 to print or pause printing according to the existence state, so as to realize the printing at any time of the label peeling printing structure 100, that is, print one label 211, and when the label 211 is taken away for pasting, the printing head 111 prints the next label 211, which is helpful to improve the packaging efficiency and the delivery efficiency, and has a good use effect.

The present embodiment also provides a label 211 printer that includes the label peeling and printing structure 100 described above. Since this label 211 printer includes the label peeling printing structure 100 described above, it also has all the advantageous effects of the label peeling printing structure 100.

Referring to fig. 1 and fig. 2, the present embodiment also provides a control method for controlling the label peeling print structure 100, where the label peeling print structure 100 may be the above label peeling print structure 100, in other words, the controller of the above label peeling print structure 100 may execute the control method.

The control method comprises the following steps:

and S01, acquiring the signal output by the detecting element 118.

The detecting member 118 detects the presence state of the peeled label 211, and when the peeled label 211 is present at the detecting member 118, the detecting member 118 outputs a first signal, specifically, the first signal is a low level signal; when the label 211 peeled off at the detecting member 118 is not present, the detecting member 118 outputs a second signal, specifically, a high level signal.

S02: in a case where the signal acquired to be output from the detection piece 118 is the first signal, the print head 111 is controlled to suspend printing.

If the label 211 peeled off at the detecting member 118 exists, it indicates that the label 211 peeled off is not removed, and at this time, the detecting member 118 detects the label 211, and the voltage value thereof is low level, and outputs a low level signal representing the existence of the label 211 peeled off as the first signal. At this point the print head 111 pauses printing while the print job can continue to be issued.

And S03, controlling the indicator light to flash.

Upon acquisition of the first signal, the control indicator lamp blinks to prompt the user to take away the tag 211. Steps S02 and S03 may be performed simultaneously, or may be performed sequentially.

S04: when the signal output to the detection member 118 is the second signal, the print head 111 is controlled to print.

If the label 211 peeled off at the detecting member 118 does not exist, it indicates that the peeled label 211 is removed, and at this time, the detecting member 118 does not detect the label 211, and the voltage value thereof is high level, and a high level signal indicating that the peeled label 211 does not exist is output as the second signal. At this time, the print head 111 can perform the next printing according to the print job.

S05: the peeling roller 114 is controlled to operate to bring the backing paper 212 into motion, and the label 211 is peeled off the backing paper 212 and moved to the detecting member 118.

After printing is completed, the peeling roller 114 is controlled to rotate, so that the backing paper 212 is conveyed from the first conveying channel 116 to the second conveying channel 117, when the backing paper 212 at the label 211 moves to the peeling shaft 113 and continues to move to the second conveying channel 117, the label 211 is peeled off from the backing paper 212 and moves to the detecting member 118 along the extending direction of the first conveying channel 116 along with the movement of the backing paper 212, and then is detected by the detecting member 118.

S06: print jobs in the RAM are acquired.

S07: when the print job in the RAM is zero and the acquired signal output by the detector 118 is the second signal, the control indicator is turned on constantly.

S08: when the print job in the RAM is not zero and the acquired signal output by the detector 118 is the second signal, the control indicator is turned off.

The label peeling printing structure 100 further includes a RAM (random access memory), the print data is temporarily stored in the RAM, when there is unfinished print content in the RAM, it indicates that the print job in the RAM is not zero at this time, so when the peeled label 211 is removed, that is, when the signal output by the detecting element 118 is the second signal, the print head 111 performs the next print according to the print content in the RAM, when printing, the indicator light is turned off, after printing and peeling the label 211, the detecting element 118 outputs the first signal, the print head 111 suspends printing until the label 211 is removed, and so on, until there is no unfinished print content in the RAM, and when the detecting element 118 outputs the second signal, that is, when the print job is zero, and the peeled label 211 is removed, the control indicator light is normally turned on, and the print job is ended.

The above description is only for the specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
