A kind of spinning method, be that technology is most mature in current various novel spinnings, most widely used spinning technique.By revolving cup
The mode that interior negative pressure generates, can be divided into self air exhaust and bleeder two major classes.The revolving cup rim of a cup of air suction type rotor spinning machine with it is defeated
There are certain gap between fine upper channel, blower takes the air-flow in revolving cup from this gap away, and the negative pressure formed in cup makes
Single fiber after shredding enters in revolving cup through defeated fine channel with filling into air-flow, and single fiber is in the high-speed rotating centrifugation masterpiece of revolving cup
Under, be slid onto the collection surface at revolving cup maximum inner diameter along the smooth inner wall of revolving cup, and close and form fibrae circulares item, connector at
Ribbon after function leaves collection surface with tail yarn, and is gone back to twisting resultant yarn by the height of revolving cup simultaneously, then through navel, doffing tube
It is drawn out and is wound into yarn reel.The yarn formation structure of the common T-type revolving cup of cotton spinning is similar to ring spun yarn, there is strength height, item to make a good job of,
The few feature of filoplume.
When the unexpected power down of rotor spinning machine complete machine is stopped, each spindle in middle section yarn when power down is stopped stays tail movement to stop
Only, to complete yarn stays tail movement generally using manual operation, and manual operation heavy workload, working efficiency is low, besides logical
Multi-functional automation control is crossed to complete, but this multifunction automatic control structure is complicated, use cost is high, it is difficult to push away extensively
Row, versatility is not strong, still cannot replace manual operation completely.
Utility model content
For the comprehensively solve above problem, in particular for deficiency of the prior art, the utility model provides one
Yarn feeding device being capable of the comprehensively solve above problem more than the small car type yarn conveying of kind rotor spinning machine joint and absorption.
To achieve the above object, the utility model uses following technological means:
The synchronous power-off control system middle section power taking structure of a kind of rotor spinning machine, comprising: AC power source, frequency converter, public

Connect with common DC bus, the middle section Switching Power Supply is connect with common DC bus, the middle section Switching Power Supply directly from
Electricity is taken on common DC bus.
As supplement to above-mentioned technical proposal and perfect, the utility model further includes following technical characteristic.
The power input of the frequency converter is electrically connected by breaker with AC power source.When occur it is serious overload or
Breaker energy automatic shutdown circuit when the failures such as short-circuit and under-voltage, so that AC power source and frequency converter be protected not to be destroyed.
The breaker is automatic air-break switch.Automatic air-break switch has safe operation reliable operation easy to use
The advantages that replacing element (such as melt) is not needed (after such as short trouble excludes) after simple movement is installed, can be effectively protected
AC power source and frequency converter.
The dc bus of the frequency converter and the junction of common DC bus 3 and middle section Switching Power Supply and public direct-current are female
The junction of line is respectively arranged with fastp-acting fuse.Fastp-acting fuse can be used to protect the frequency conversion hung on common DC bus
The capacitor cell and middle section Switching Power Supply of device.
The middle section Switching Power Supply is the Switching Power Supply that DC input voitage range is 480 ~ 780VDC.Due to public straight
The voltage of stream bus can arrive 600V, and the DC input voitage range of middle section Switching Power Supply is adapted to direct current in 480 ~ 780VDC
Busbar voltage fluctuation.
The beneficial effects of the utility model are: the utility model structure is simple, and it is easy to use, it is at low cost, it is easy to push away extensively
Row, versatility is simultaneously strong, can replace manual operation completely；For the utility model instead of manual operation, operation element amount is small, operation
Work efficiency is high.
Detailed description of the invention
Fig. 1 is the circuit connection diagram of the utility model.
Specific embodiment
Specific embodiment of the present utility model is described in detail with reference to the accompanying drawing.
As shown in Figure 1, a kind of synchronous power-off control system middle section power taking structure of rotor spinning machine, comprising: AC power source 1,
Frequency converter 2, common DC bus 3, motor 4, middle section Switching Power Supply 5, the power input and AC power source 1 of the frequency converter 2
Connection, tri- terminals of U/V/W of motor 4 are connect with tri- terminals of U/V/W of frequency converter 2, and described 4 turns of 2 driving motor of frequency converter
Dynamic, the dc bus of all frequency converters 2 is connect with common DC bus 3, the middle section Switching Power Supply 5 and common DC bus 3
Connection, the middle section Switching Power Supply 5 directly take electricity from common DC bus 3.
The power input of frequency converter 2 be electrically connected by breaker 21 with AC power source 1, overload when generation is serious or
21 energy automatic shutdown circuit of breaker when the failures such as short-circuit and under-voltage, so that AC power source 1 and frequency converter 2 be protected not to be destroyed.
