Spinning, automatic cutting device for spinning
Technical field: spinning, the spinning field, a kind of critical component that is used for automatic winder---spinning, automatic cutting device for spinning, be used for spinning simultaneously, the elasticizer of spinning, spinning machine, spooler, doubler twister, doubling winder, the groove drum car, the wrap yarn machine, the covering filament machine, the automatic chopping of network yarn machine, the yarn cutting device, when these machines with the yarn more than two and two, silk, line (for convenience's sake, yarn before below synthetic, silk, line is called for short yarn, yarn after synthetic, silk, line is called for short yarn) when synthesizing an one thread, as wherein one or a few breaks, spinning, automatic cutting device for spinning can cut off remaining yarn together, guarantee that the yarn that is synthesized can not lack composition wherein, to guarantee that yarn qualities is qualified.
Background technology: the bobbin winder of prior art divides by the mode that drives generally two kinds, be that single ingot drives and the complete machine interlock, the automatic winder of the existing domestic and imported that uses all adopts single ingot type of drive, when (shown in Figure of description 1) this automatic winder synthesizes an one thread with the yarn more than two and two, as wherein one or a few breaks, adopt the mode of left alone without help motor (being left alone without help rolling out) to reach yarn that assurance synthesizes and can not lack wherein composition, to guarantee that yarn qualities is qualified around spindle.But price is rather stiff is high, and the maintenance cost height, and power consumption is more much bigger than complete machine interlock, and output does not have the height of complete machine interlock, can not reach ideal effect to the winder moulding.Because the develop rapidly of science and technology is more and more higher to the requirement of winder moulding as extensively trying out of present various spinning, spinning two-for-one twister, adopt the automatic winder of complete machine interlock to come out as yet simultaneously.
Summary of the invention: shown in Figure of description 2, the present invention adopts capacitance sensor A, yarn in each ceramic trough E that main effect is capacitance sensor A is under the normal straight motion conditions and operate as normal, the yarn F of each the ceramic trough E that is positioned at capacitance sensor A stagnate or the situation of breaking under, the ceramic trough E of the stagnation or the corresponding capacitance sensor A that breaks can sense electric quantity signal, by amplifying circuit B above electric quantity signal is amplified, the executing agency C that the electric quantity signal control Electromagnetic Drive of having amplified is arranged again, when going here and there the yarn of ceramic trough E, wherein one or a few stagnation or break and lose one or several ceramic trough E of capacitance sensor A produced and do the time spent, the C of executing agency can cut off remaining yarn before entering winding spindle K together, guarantee that the yarn that is synthesized can not lack composition wherein, to guarantee the qualified of yarn qualities, owing to cut off entering the preceding yarn of winding spindle K, so do not need left alone without help rolling out around spindle, the winding spindle of entire machine can not turn round under the driving of same motor not left alone without helply, reach the automatic winder effect of complete machine interlock, capacitance sensor A can be provided with the switch of each ceramic trough E correspondence simultaneously, can conveniently increase or reduce the radical of yarn F, to satisfy the various processes needs, and arbitrary C of executing agency is after cutting off yarn, there are indicator lamp flash of light, prompting operation worker in the capital.
Description of drawings: Figure of description 1, Figure of description 2 is in Figure of abstract three width of cloth accompanying drawings; Figure of description 1 is used for illustrating the key component in the existing automatic winder, i.e. amplification of Yarn break checkout gear A, prior art and control circuit H, electric motor I.Figure of description 2 is used for illustrating the key component of automatic yarn cutting device for spinning of the present invention, i.e. the amplification of capacitance sensor A, spinning of the present invention, automatic cutting device for spinning and control circuit B, the C of executing agency.Marginal data: A: capacitance sensor; B: amplify and control circuit; C: executing agency; D: ceramic trough; E: the ceramic trough of capacitance sensor A; F: the yarn before synthetic; G: the yarn after synthetic; H: the amplification of prior art and control circuit; I: the motor that is used for driving single ingot spindle; J: be used for the spindle of single driving; K: be used for the whole spindle that drives; U: insert power supply.
The specific embodiment: the present invention adopts capacitance sensor A, yarn in each ceramic trough E that main effect is capacitance sensor A is under the normal straight motion conditions and operate as normal, the yarn F of each the ceramic trough E that is positioned at capacitance sensor A stagnate or the situation of breaking under, the ceramic trough E of the stagnation or the corresponding capacitance sensor A that breaks can sense electric quantity signal, by amplifying circuit B above electric quantity signal is amplified, the executing agency C that the electric quantity signal control Electromagnetic Drive of having amplified is arranged again, when going here and there the yarn of ceramic trough E, wherein one or a few stagnation or break and lose one or several ceramic trough E of capacitance sensor A produced and do the time spent, the C of executing agency can cut off remaining yarn before entering winding spindle K together, guarantee that the yarn that is synthesized can not lack composition wherein, to guarantee the qualified of yarn qualities, owing to cut off entering the preceding yarn of winding spindle K, so do not need left alone without help rolling out around spindle, the winding spindle of entire machine can not turn round under the driving of same motor not left alone without helply, reach the automatic winder effect of complete machine interlock, capacitance sensor A can be provided with the switch of each ceramic trough E correspondence simultaneously, can conveniently increase or reduce the radical of yarn F, to satisfy the various processes needs, and arbitrary C of executing agency is after cutting off yarn, there are indicator lamp flash of light, prompting operation worker in the capital.The operative employee inserts the yarn that breaks after finding again, utilizes the left alone without help car device of winding spindle to make the work of winding spindle stop again, finds out the loose thread that is positioned on the winding spindle spool and connects, and finishes once-through operation.Spinning of the present invention, automatic cutting device for spinning are mainly used in elasticizer, automatic winder, automatic spooler, spinning machine, spooler, winder, doubler twister, doubling winder, doubling winder, groove drum car, wrap yarn machine, covering filament machine, the automatic chopping of network yarn machine, the yarn cutting device of spinning, spinning.
