Abstract
The utility model discloses a flow rate feedback device used for a throttle motor of a circular knitting machine. It comprises the throttle motor for supplying wind force, a blanking mouth and a receiving bag; The blanking mouth is arranged above the receiving bag; The blanking mouth is open, and a mounting hole is on the sidewall of the blanking mouth; it also includes a suction duct; One end of the suction duct is fixed and installed on the blanking mouth by the mounting hole on the side wall of the blanking mouth, the other end of the suction duct is connected with the throttle motor; The suction duct equips with a negative pressure mouth which is connected with a control chip and the throttle motor; Signals detected by the negative pressure sensor are transmitted to the control chip, and the control chip according to a preset program controls the throttle motor to start or stop. Through implementation, the fabric length consistency of the machine output can be ensured, and the fabric output trouble caused by too small suction wind force or the output fabric stretched by too big suction wind force will not occur, so customer requirements are satisfied and the machine failure rate is reduced.
Description
Technical field
The utility model relates to technical field of knitting machinery, especially relates 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 component: frame, rotationally be arranged at syringe on frame, be movably set in knitting needle on syringe, relatively syringe be fixedly installed on knitting needle on frame drive triangle, relatively syringe be fixedly installed on the slide cam selector that is used for selecting needle motion on frame, relatively the syringe circumference Yarn supply device, syringe drive unit, be arranged at opening tying device, collecting machine directly over syringe.And the suction fan that arranges on present computer seamless underclothes knitting machine is the shared form existence of multiple computer desk collective, 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 the uninterrupted of regulation and control air draught in real time 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 utility model provides a kind of damper motor flow feedback assembly for circular knitter, reaches 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 a mounting hole is arranged on the blanking port sidewall; It also comprises an aspiration channel, and described aspiration channel one end is fixedly mounted on 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 to 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 on aspiration channel, described negtive-pressure implement sensing cover for seat is fixed with being arranged on aspiration channel and by fixture, and a through hole is arranged on the negative pressure transducer seat; 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 to, connection wire on 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, due to the closed-loop control mechanism of negative pressure transducer and damper motor composition, by the sizes values of setting negative pressure in program, thereby realize 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 extremely 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 program.
By enforcement of the present utility model, 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 the present embodiment.
Embodiment
Referring to accompanying drawing.The 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 on blanking port 1 sidewall, a mounting hole is arranged; It also comprises an aspiration channel 5, and described aspiration channel 5 one ends are fixedly mounted on 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 on 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 arranged on aspiration channel 5 and by fixture to be fixed, and a through hole is arranged on negative pressure transducer seat 4; Described negtive-pressure implement sensor 4 is fixedly mounted on 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 described negative pressure transducer 4 is drawn by through hole on negative pressure transducer seat 3, sealed by seal, final sum damper motor and control chip are connected, and form a close loop control circuit by negative pressure transducer 4, damper motor and control chip.
During device work, the closed-loop control mechanism because negative pressure transducer 4 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 extremely 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 program.
By the enforcement of the 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.
