Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and be easy to understand with effect, under
Face combines and is specifically illustrating, and this utility model is expanded on further.
See Fig. 1-5:
A kind of high-speed production lines cigarette infrared detector, mainly includes infrared detector and infrared electro detection
Device connecting plate, described infrared detector is connected on infrared detector connecting plate;
Described infrared detector includes a housing 1, is provided with sensitivity adjusting button 2, LED action on housing 1
Display lamp 3 and pricking with needle 4, post labeling 5 on housing 1 surface, and described pricking with needle 4 is arranged in housing 1 by casting glue 6, Qi Zhonghong

Receiving range;
Described infrared detector connecting plate includes PCB 7, the row-needle receptacle 8 that is arranged in PCB 7, jumps
Line cap 9 and binding post 10, also include the outer infrared ray transceiving head joined;Described pricking with needle 4 is arranged on row-needle receptacle 8, and described LED moves
Make display lamp 3, sensitivity adjusting button 2 is connected with PCB 7.
It is honorable by being installed on detectable substance that Multifunction infrared photoelectricity receives detector, by external infrared receiver, launches and visits
Head detects, and production line packaging cigarette or tobacco bale pass through in the middle of infrared receiver, transmitting probe.Infrared light is unobstructed
Time, machine time delay runs shuts down, i.e. without cigarette or tobacco bale state;When having cigarette or tobacco bale and passing through from centre, keep packaging
Machine is in operation, and infrared detector detects the optical signal of cigarette or tobacco bale, through internal circuit amplification, shaping, synchronizes,
Phase, output are amplified, and the output signal output that infrared detector is detected is sent to the single-chip microcomputer of main frame and carries out tally control,
Thus the packaging quantity of high-speed production lines packer is accurately controlled;Ensure often bag packaging quantity, it is to avoid leakage, branched
Mass defect, affects the packaging of product and causes unnecessary packaging to waste.
Infrared frequency agitator is produced by digital integrated electronic circuit amplifier U1C, resistance R8, electric capacity C12, through digital integration electricity
After road U1A amplifies shaping, deliver to the anti-phase amplification of digital integrated electronic circuit U1B respectively, transistor T4 emitter stage export contact pin X1-
10, then launched infrared light by external infrared emission head;Transistor T5 basis set is delivered to through resistance R10 in another road, by T5 as red
Outer frequency sending and receiving synchronous selection pass switching signal.
After being received infrared signal by the external infrared receiving terminal of contact pin X2-1, control receiving sensitivity through potentiometer RX, by electricity
After holding the frequency-selecting amplification that C19 is input to the compositions such as digital integrated electronic circuit U2F, U2E, U2D;It is sent to transistor T5 emitter stage, then by
