Description
Technical field
The utility model relates to a kind of circular knitting machine, especially relates to a kind of Knitting circular machine photoelectric reaction cloth dropping alarm device that is installed on the circular knitting machine.Belong to technical field of textile machine.
Background technology
Circular knitting machine is the high-grade knitted machine in numerous Knitting Machinery, is characterized in that yield in unit time is big, the product specification height.Circular knitting machine generally has 100 threads to give yarn simultaneously.In the course of the work, the broken yarn situation can occur, under the tension force influence in the external world, can cause the cropping phenomenon, the cloth cover breach promptly occur, tension force is big more, and breach is also increasing.In general, under the very little situation of cloth cover breach, can pass through artificial repairing breach, repair.If but breach is very big, then can't repair, cause substandard products to produce.Therefore, need a kind of device that can just can judge cropping phenomenon and warning in the very first time.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and providing a kind of can just can judge cropping phenomenon and the Knitting circular machine photoelectric reaction cloth dropping alarm device of reporting to the police in the very first time.
The purpose of this utility model is achieved in that a kind of Knitting circular machine photoelectric reaction cloth dropping alarm device, it is characterized in that described warning device comprises an alarm host machine, several detection probe and reflexed light film,
Several detection probe are installed in several positions on the brandreth of rotating cylinder inner rotator of circular knitting machine, provide power supply by the rotor brush,
Reflexed light film is attached to the inner edge of the cylindric syringe of circular knitting machine,
Described detection probe comprises infrared transmitter and two parts of infrared remote receiver,
Described alarm host machine comprises amplifying circuit I, frequency selection circuit, amplifying circuit II, A/D converter, CPU and alarm, the infrared remote receiver of detection probe links to each other with amplifying circuit I input, the output of amplifying circuit links to each other with the frequency selection circuit input, the frequency selection circuit output links to each other with amplifying circuit II input, amplifying circuit II output links to each other with the A/D converter input, the A/D converter output links to each other with CPU, and CPU links to each other with alarm with the control system of circular knitting machine.
The utility model can detect the duty of circular knitting machine, if there is the cropping situation to take place, then reports to the police.
Description of drawings
Fig. 1 is the general structure schematic diagram of the utility model Knitting circular machine photoelectric reaction cloth dropping alarm device.
Fig. 2 is the work block diagram of the utility model Knitting circular machine photoelectric reaction cloth dropping alarm device.
Fig. 3 is the alarm host machine circuit block diagram of the utility model Knitting circular machine photoelectric reaction cloth dropping alarm device.
The specific embodiment
Referring to Fig. 1～2, the Knitting circular machine photoelectric reaction cloth dropping alarm device that the utility model relates to mainly is made up of an alarm host machine and several detection probe.Several detection probe are installed in several positions on the brandreth of rotating cylinder inner rotator of circular knitting machine, provide power supply by the rotor brush, the rotating cylinder that several detection probe are followed circular knitting machine rotates together, all the time the cloth cover that the scanning syringe that does not stop is just casted off, progressively fallen, (thousands of pins of circular knitting machine all are installed in around the metal tub thing the cylindric syringe in cloth cover periphery, and term is called syringe.), the syringe inner edge sticks the reflective membrane of aluminium foil and so on.Described detection probe comprises infrared transmitter and two parts of infrared remote receiver, and infrared remote receiver links to each other with alarm host machine by connecting line.
Referring to Fig. 3, described alarm host machine mainly is made up of amplifying circuit I, frequency selection circuit, amplifying circuit II, A/D converter, CPU and alarm.The infrared remote receiver of detection probe links to each other with amplifying circuit I input, the output of amplifying circuit links to each other with the frequency selection circuit input, the frequency selection circuit output links to each other with amplifying circuit II input, amplifying circuit II output links to each other with the A/D converter input, the A/D converter output links to each other with CPU, and CPU links to each other with alarm with the control system of circular knitting machine.Alarm host machine also comprises display, keyboard, the fetch interface of CF card and USB flash disk and various communication interface.
Operation principle:
The infrared transmitter of detection probe is launched the pulse signal of high frequency, if run into normal cloth cover, does not then produce reflective; If run into the cropping situation; then the infrared light that sends of infrared transmitter shines directly on the reflective membrane at the cloth cover back side after by the cloth cover breach; produce reflective; this heliogram is received by infrared remote receiver; and deliver to alarm host machine by connecting line; the signal that the amplifying circuit I of alarm host machine is faint with this amplifies; the frequency selection circuit frequency-selecting; amplifying circuit II is again after the amplification work; friendship has the AD converter collection to become numerical quantities; after high-speed CPU obtains this digital quantity; by certain algorithm; whether the result of calculation of comprehensive all probe passages judge cropping; and by the shutdown of output interface order large circle machine, and report to the police, on the LCD of main frame, point out concrete cropping position.
