SELF-ADHESIVE LABEL INKJET PRINTER CONTROL DEVICE Technical Field
The invention relates to the field of self-adhesive label printer supporting facilities, in
particular to a self-adhesive label inkjet printer control device.
Background
A self-adhesive label inkjet printer is a piece of widely used equipment, and is mainly used
for printing self-adhesive labels of products by manufacturers, sales field, etc. When working, an
inkjet head and related components of a printer are under the control of a pc program to print
patterns designed by a user through a pc on the surface of a label. As existing inkjet printers are
limited by inherent working performance, the inkjet printers are not suitable for batch printing
work. An inkjet printer generally prints less than 100 pages when working continuously, and
long-time printing and working in fatigue state will accelerate the aging of the printer. Generally,
after printing dozens of sheets, the speed of the printer will become slower and slower, which
will affect the work progress.
Due to the limitations of the inkjet printer, in practical applications, the user generally stops
the printer after working for a period of time, and then lets the printer work again after a time
interval; therefore, the printer can be used in the cases where a small amount of labels need to be
printed, but for manufacturers and other cases that require a large amount of labels, due to the
long printing interval, work efficiency will be undoubtedly and seriously reduced, and work
progress will be affected. If two printers are used to work at intervals, although one printer can
be controlled to work when the other printer stops working intermittently, two PCs are needed to
drive the two printers separately in this mode; the use of two PCs not only increases the cost but
also is inconvenient to store; in addition, during work, the user need to manually control the two
printers to work or stop within a certain period of time; therefore, it will increase the workload of
the user and bring certain inconvenience to the user.
For the above reasons, it is particularly necessary to provide a self-adhesive label printer
control device which uses one PC to control two inkjet printers to work alternately, requires no manual operation during work at all, can prompt the user in time when printing paper is used up, and achieves the purposes of automatic control and improving work efficiency.
Summary
In order to overcome the defects of the existing inkjet printers for label printing that two PCs
are needed to separately control the work of two printers, manual operation is needed to switch
between work and stop, the operation is inconvenient for users, automatic control cannot be
achieved, and the cost of use is relatively high, the invention provides a self-adhesive label inkjet
printer control device which uses one PC to control two inkjet printers to work intermittently,
requires no manual operation during work at all, can give an audio prompt to a user as soon as
possible when self-adhesive labels to be printed are used up, and achieves the purposes of having
low cost and automatic control, bringing convenience to users and improving work efficiency.

circuit board is installed in an element box; the element box is installed on the inner rear side of
the housing; a 220V AC power supply is respectively connected with two power input ends of a
PC, two self-adhesive label inkjet printers and the switching power supply by wires; two power
output ends of the switching power supply are respectively connected with two power input ends
of the time controller and the two photoelectric switches by wires; a negative power output end
of the switching power supply is connected with a negative power input end of the buzzer by a
wire; positive power output ends of the two photoelectric switches are connected with a positive
power input end of the buzzer by wires; one USB plug is plugged into a USB socket of the PC; two data terminals of one USB plug are respectively connected with two control power input ends of the time controller by data wires; two terminals of one signal output end of the time controller are respectively connected with two data terminals of a second USB plug by data wires; two terminals of a second signal output end of the time controller are respectively connected with two data terminals of a third USB plug by data wires; and the second and the third USB plugs are respectively plugged into USB sockets of the two self-adhesive label inkjet printers.

The invention can use one PC to control two inkjet printers to work intermittently, requires no
manual operation during work at all, and can give an audio prompt to a user by the buzzer as
soon as possible when self-adhesive labels to be printed are used up. The invention achieves the
purposes of having low cost and automatic control, bringing convenience to users and improving
work efficiency. For the above reasons, the invention has a good application prospect.

B will be energized and emit a loud warning sound, so as to prompt the user that the
self-adhesive label paper roll(s) 12 to be printed in one or both of the two self-adhesive label
inkjet printers DYl and DY2 is (are) used up, and a new self-adhesive label paper roll(s) to be
printed shall be equipped in time to ensure the normal operation of the self-adhesive label inkjet
printer(s). In the invention, since pins 3 of the photoelectric switches IC3 and IC4 are connected
with the positive power input end of the buzzer B, as long as one printer is out of paper, the
buzzer B will make a sound, which ensures the normal operation of the printer. In order to
achieve a reliable alarm, the two printers are placed on a desktop, etc.; after being printed, the
printing paper is continuously output and falls to a lower position such as the desktop; therefore,
after the printing paper is printed, under the action of gravity, the rear end of the printing paper
will fall downward from the middle part of the lower end of the label outlets 9 of the two
self-adhesive label inkjet printers and the transverse openings 10 at the front end of the housing,
so as to ensure that the upper detecting heads of the photoelectric switches will not be blocked after the printing paper is used up. The invention achieves the purposes of having low cost and automatic control, bringing convenience to users and improving work efficiency. For the above reasons, the invention has a good application prospect. In Fig. 3, the brand of the relay KI is
Songle, the model is SLA-12VDC-SL, and the relay KI has two power input ends, two control
power input ends, two normally closed contact ends and two normally open contact ends.
