Abstract
The invention discloses an air door electric motor flow feedback device for a round knitting machine. The air door electric motor flow feedback device comprises an air door motor for providing wind power, a blanking port and a material collecting bag, wherein the blanking port is arranged above the material collecting bag; and the blanking port is opened, and an installation hole is arranged on the lateral wall of the blanking port. The air door electric motor flow feedback device further comprises an air suction tube, wherein one end of the air suction tube is fixedly installed on the blanking portion through the installation hole on the lateral wall of the blanking port, and the other end of the air suction tube is connected with the air door motor; a negative pressure sensor is arranged on the air suction tube and in electric connection with a control chip and the air door motor; and the negative pressure sensor transmits the detected signals to the control chip which accordingly controls the on and off of the air door motor according to a preset program. By means of the air door electric motor flow feedback device for the round knitting machine, the lengths of textiles output by a machine table are identical, the problem that the textiles are difficult to output due to too small air suction force and the output textiles can be lengthened due to overlarge air suction force can be solved, accordingly requirements of customers can be met, and happening of machine fault can be reduced.
Description
Technical field
The present invention relates to technical field of knitting machinery, especially relate to a kind of damper motor flow feedback assembly for circular knitter.
Background technology
Existing have the seamless underwear knitting machine mainly by forming with lower member: frame, rotationally be arranged at syringe on the frame, be movably set in knitting needle on the syringe, relatively syringe be fixedly installed on knitting needle on the frame drive triangle, relatively syringe be fixedly installed on the slide cam selector that is used for selecting needle motion on the frame, relatively the syringe circumference Yarn supply device, syringe drive unit, be arranged at opening tying device, collecting machine directly over the syringe.And the suction fan that arranges on the computer seamless underclothes knitting machine at present to be multiple computer desk collective share form exists, different because of each machine present position in concrete use procedure, corresponding air draught power difference in size is larger, and a kind of mechanism of in real time regulation and control air draught uninterrupted is not set, so fabric stressed not of uniform size causing in output procedure, cause the fabric length of each board output inconsistent, thereby affect fabric quality and outward appearance.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of damper motor flow feedback assembly for circular knitter, reach improvement purpose.
For this reason, provide following technical scheme: a kind of damper motor flow feedback assembly for circular knitter, it comprises that one provides damper motor, a blanking port and a rewinding bag of wind-force, described blanking port is above the rewinding bag; Described blanking port is uncovered, and at the blanking port sidewall one mounting hole is arranged; It also comprises an aspiration channel, and described aspiration channel one end is fixedly mounted on the blanking port by the mounting hole on the blanking port sidewall, and the aspiration channel other end is connected with damper motor; It is characterized in that: aspiration channel is provided with negative pressure transducer, is electrically connected with control chip and damper motor; Negative pressure transducer is transferred to control chip with the signal that detects, and control chip is controlled thus damper motor according to default program and opened and closed.
Further, be provided with a negative pressure transducer seat at aspiration channel, described negtive-pressure implement sensing cover for seat is fixed with being installed on the aspiration channel and by fixture, at the negative pressure transducer seat one through hole is arranged; Described negtive-pressure implement sensor is fixedly mounted on the negative pressure transducer seat, and negative pressure transducer and damper motor and control chip are electrically connected, connection wire on the described negative pressure transducer is drawn by through hole on the negative pressure transducer seat, sealed by seal, finally form a close loop control circuit by negative pressure transducer, damper motor and control chip.
During device work, because the closed-loop control mechanism that negative pressure transducer and damper motor form by the sizes values of setting negative pressure in program, thereby realizes in real time the air draught uninterrupted being carried out quantified controlling and adjusting.Under programmed control, when the suction air volume size of each board unusually satisfies the setting negative pressure value (the air draught flow is excessive or too small), described negative pressure transducer produces the electric signal sensor alarming by air draught pressure, this moment, damper motor carried out regulation and control to air draught flow negative pressure value size, made negative pressure value satisfy setting value in the program.
By enforcement of the present invention, can guarantee that the fabric length of each board output is consistent, can not occur causing because air draught power is too small that fabric output difficulty and air draught power are excessive causes exporting fabric and be elongated, thereby satisfy the generation of customer requirement and reduction machine-spoiled rate.
Description of drawings
Fig. 1 is the structural representation of present embodiment.
Embodiment
Referring to accompanying drawing.Present embodiment comprises that one provides damper motor, a blanking port 1 and a rewinding bag 2 of wind-force, and described blanking port 1 is above rewinding bag 2; 1 mouthful of described blanking is uncovered, and at blanking port 1 sidewall one mounting hole is arranged; It also comprises an aspiration channel 5, and described aspiration channel 5 one ends are fixedly mounted on the blanking port 1 by the mounting hole on the blanking port sidewall, and aspiration channel 5 other ends are connected with damper motor; Be provided with a negative pressure transducer mechanism at aspiration channel 5, described negative pressure transducer mechanism comprises a negative pressure transducer 4 and a negative pressure transducer seat 3, described negtive-pressure implement sensing seat 4 overlaps and is installed on the aspiration channel 5 and by fixture to be fixed, and at negative pressure transducer seat 4 through hole is arranged; Described negtive-pressure implement sensor 4 is fixedly mounted on the negative pressure transducer seat 3, and negative pressure transducer 4 has the wire that is connected with damper motor and control chip, connection wire on the described negative pressure transducer 4 is drawn by through hole on the negative pressure transducer seat 3, sealed by seal, final sum damper motor and control chip link to each other, and form a close loop control circuit by negative pressure transducer 4, damper motor and control chip.
During device work, because negative pressure transducer 4 and the closed-loop control mechanism that damper motor forms by the sizes values of setting negative pressure in program, thereby are realized in real time the air draught uninterrupted being carried out quantified controlling and adjusting.Under programmed control, when the suction air volume size of each board unusually satisfies the setting negative pressure value (the air draught flow is excessive or too small), described negative pressure transducer 4 produces the electric signal sensor alarming by air draught pressure, this moment, damper motor carried out regulation and control to air draught flow negative pressure value size, made negative pressure value satisfy setting value in the program.
By the enforcement of present embodiment, can guarantee that the fabric length of each board output is consistent, can not occur causing because air draught power is too small that fabric output difficulty and air draught power are excessive causes exporting fabric and be elongated, thereby satisfy the generation of customer requirement and reduction machine-spoiled rate.
