Description
Technical field
This utility model relates to a kind of air bubble machine control circuit, particularly a kind of air bubble machine clutch and brake control circuit.
Background technology
Air bubble machine is when producing bubble chamber film, when needing to carry out cutting or putting disconnected process by certain length segmentation pause, typically can design a set of clutch-brake control system device, but it is higher to be because machine operation efficiency, cross material roller meeting spinning movement more than 40,000 time in a day, owing to electric current can be produced when brake clutch brake control is inductive load use, control brake clutch brake the most on the market and control to be all to use to have contact line ring type device, in the case of work continuously, often break down in this apparatus system contact, frequently change accessory, production capacity can be reduced, increase a large amount of production cost.
Utility model content
The purpose of this utility model is that to be to solve clutch-brake in existing air bubble machine shorter for service life so that the frequency that equipment breaks down is higher, and provides a kind of air bubble machine clutch and brake control circuit.
The technical scheme that this utility model solves above-mentioned technical problem is as follows: a kind of air bubble machine clutch and brake control circuit, described control circuit includes master control normal open switch, master control normally closed switch, first interrupt control unit, second interrupt control unit, first clutch-brake, second clutch-brake, first sub-control bi-directional thyristor switch and the second sub-control bi-directional thyristor switch, described master control normal open switch and the first clutch-brake are connected in series, the input of described master control normal open switch and the first sub-control bi-directional thyristor switch connects, the outfan of described first sub-control bi-directional thyristor switch is connected with positive source, the control end of described first sub-control bi-directional thyristor switch and the first interrupt control unit connect；Described master control normally closed switch and the second clutch-brake are connected in series, the input of described master control normally closed switch and the second sub-control bi-directional thyristor switch connects, the outfan of described second sub-control bi-directional thyristor switch is connected with positive source, and the control end of described second sub-control bi-directional thyristor switch and the second interrupt control unit connect.
Further, described control circuit is provided with two groups.
Further, described first sub-control bi-directional thyristor switch and the second sub-control bi-directional thyristor switch are contactless light idol bi-directional thyristor switch.

Technique scheme is used to provide the benefit that: a reverse side effectively raises the service life of brake clutch brake in air bubble machine, and still further aspect comprehensively improves production efficiency.
Accompanying drawing explanation
Fig. 1 is circuit diagram described in the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing and currently preferred specific embodiment, present disclosure is further described.Example is served only for explaining this utility model, is not intended to limit scope of the present utility model.
As shown in fig. 1, a kind of air bubble machine clutch and brake control circuit described in this programme, described control circuit includes master control normal open switch KA1, master control normally closed switch KA2, first interrupt control unit KS1, second interrupt control unit KS2, first clutch-brake M1, second clutch-brake M2, first sub-control bi-directional thyristor switch SSR1 and the second sub-control bi-directional thyristor switch SSR2, described master control normal open switch KA1 and the first clutch-brake M1 is connected in series, the input of described master control normal open switch KA1 and the first sub-control bi-directional thyristor switch SSR1 connects, the outfan of described first sub-control bi-directional thyristor switch SSR1 is connected with positive source, the control end of described first sub-control bi-directional thyristor switch SSR1 and the first interrupt control unit KS1 connect；Described master control normally closed switch KA2 and the second clutch-brake M2 is connected in series, the input of described master control normally closed switch KA2 and the second sub-control bi-directional thyristor switch SSR2 connects, the outfan of described second sub-control bi-directional thyristor switch SSR2 is connected with positive source, and the control end of described second sub-control bi-directional thyristor switch SSR2 and the second interrupt control unit KS2 connect；Circuit above-mentioned in this programme is respectively provided with two groups；Described in this programme, the first sub-control bi-directional thyristor switch SSR1 and the second sub-control bi-directional thyristor switch SSR2 is contactless light idol bi-directional thyristor switch；The DC voltage that running voltage is 24V of contactless light idol bi-directional thyristor switch described in this programme, the operating current of described contactless light idol bi-directional thyristor switch is 3A to 5A.
nullWhen being embodied as，The rapid break-make performance utilizing light idol bidirectional triode thyristor IGCT adds that the advantage of 24V DC low-voltage can load required electric current 3A to 5A，And system without deaerator break-make，By the first interrupt control unit KS1、Second interrupt control unit KS2、The normally-open normally-close point output of the 3rd interrupt control unit KS3 and the 4th interrupt control unit KS4 is connected to the first clutch-brake M1、Second clutch-brake M2、3rd clutch-brake M3 and the coiler part of the 4th clutch-brake M4，At the first clutch-brake M1、Second clutch-brake M2、The electric current produced when the 3rd clutch-brake M3 and the 4th clutch-brake M4 action is by 24VDC contactless light idol bidirectional triode thyristor formula switch load，Original field coil contact switch KA1 and KA2 simply does on-off action no longer load current.Whole action is first exported by the normally opened signaling switch of making normally closed with master control normally closed switch KA2 two groups of master control normal open switch KA1 field coil two groups, the first interrupt control unit KS1, the second interrupt control unit KS2, the 24VDC contactless light idol bidirectional triode thyristor formula of the 3rd interrupt control unit KS3 and the 4th interrupt control unit KS4 switchs four groups of normally opened and normally closed some load currents to form closed loop control the first clutch-brake M1, the second clutch-brake M2, the 3rd clutch-brake M3 and the 4th clutch-brake M4.
Upper described only preferred embodiment of the present utility model, not in order to limit this utility model, all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
