Description

Control mechanism for delay start of spinning device rotor
Technical field
The invention belongs to the spinning machine part field, especially relevant with a kind of control mechanism for delay start of spinning device rotor of rotor spinning machine.
Background technology
Rotor spinning machine is a kind of open-end-spinning equipment, be illustrated in figure 1 as the spinning apparatus of semiautomatic rotor spinning machine, it mainly is made up of the sliver can of accepting successively 1, spinning organ 2, delivery device 3, semi-automatic joining device 4, wireline reel 5 and yarn tube 6, spinning organ 2 commonly used comprises that to cotton roller, combing roller 10, revolving cup 17, eave tile pull bar 11, pinch roller linkage 13, revolving cup braking mechanism 14 and brake connecting rod mechanism 12 etc. tengential belt 15 is being pressed the rotating shaft that is posted by revolving cup 17 to transmit the power that motor provides for revolving cup rotates at a high speed by pinch roller 16.During spinning, use blower fan to carry out air-breathing to spinning organ by air duct, form negative pressure in the revolving cup 17 of spinning organ, with sliver 8 feeding combing rollers 10, sliver is carded to filament 9 to cotton roller, filament 9 is sucked revolving cup 17 by negative pressure by combing roller, because revolving cup rotates at a high speed, the collection surface that filament is dumped on the revolving cup forms fibre bundle, by delivery device 3 fibre bundle that generates is drawn revolving cup, and twisting forms the yarn with twist in the spill process.Rotor spinning is finished a package or broken yarn occurs in spinning process, just need carry out joint again.Semiautomatic rotor spinning machine in the market can be realized semi-automatic joining, its joint process is: open the spinning organ movable rack, movable rack pulling eave tile pull bar, the eave tile pull bar rotates the back and has shored pinch roller and revolving cup braking mechanism by pinch roller linkage and brake connecting rod mechanism, make pinch roller rising tengential belt break away from the revolving cup rotating shaft, no longer be revolving cup rotation transferring power, the revolving cup braking mechanism is close to the revolving cup rotating shaft revolving cup is checked no longer rotation, after revolving cup stops operating the revolving cup inner chamber is cleared up, removed residual fiber and impurity; After the cleaning of revolving cup inner chamber is finished, yarn and thread head is inserted revolving cup as drawing loose thread, movable rack closes, pinch roller linkage and brake connecting rod mechanism are no longer shored in the rotation that resets of eave tile pull bar, and braking mechanism descends to breaking away from and unclamps the revolving cup rotating shaft, step-down tengential belt and is close to the revolving cup rotating shaft again and drives revolving cup and rotate at a high speed under the pinch roller, feed sliver to cotton roller, sliver becomes filament to enter revolving cup after the combing roller combing, the revolving cup collection surface with draw loose thread and combine by drawing loose thread and draw spun yarn.According to above-mentioned joint process, beginning joint operation behind the yarn broken yarn, in the joint process, stop to feed to sliver, but the cotton fiber that is positioned at the sliver head still is subjected to the combing of combing roller to cotton roller, cotton fiber can be damaged, after restarting spinning, these cotton fibers that have been damaged enter revolving cup at first and combine with drawing loose thread, can influence the quality at Yarn connecting place, form the yarn defect, thereby influence the quality of institute's yarn.Become to improve the technical barrier that semiautomatic rotor spinning machine improves the spinning joint quality so how to remove the cotton fiber that the sliver head is damaged.
Summary of the invention
Purpose of the present invention is exactly will solve that existing semiautomatic rotor spinning machine can't be removed the cotton fiber that the sliver head is damaged and the technical barrier that influences the Yarn connecting quality, provides a kind of and removes the control mechanism for delay start of spinning device rotor that is decreased fiber before making spinning organ be implemented in the spinning joint.For this reason, the present invention is by the following technical solutions:
Before drawing loose thread and insert revolving cup in the semi-automatic joining process, feed one section sliver earlier, the revolving cup time-delay is rotated, the sliver head fiber that the broken end back is damaged by combing roller enters revolving cup, being decreased fiber enters the negative pressure that is formed by air duct by blower fan behind the revolving cup and siphons away to remove and decreased fiber, and then insert revolving cup drawing loose thread, start the revolving cup rotation and normally spin.
The present invention is exactly the control mechanism for delay start of spinning device rotor that adapts to above-mentioned jointing method, comprise the eave tile pull bar, described eave tile pull bar middle part is provided with axis hole, it is characterized in that, described control mechanism for delay start of spinning device rotor also comprises eave tile draw rod positions locking device, this eave tile draw rod positions locking device is arranged at eave tile pull bar afterbody, by the position of locking eave tile pull bar afterbody, thus the position of locking eave tile pull bar.
When the present invention was to use, the shaft hole sleeve at described eave tile pull bar middle part was loaded on minor axis, and this minor axis is installed on the sidewall of spinning organ, and the eave tile pull bar is connected with pinch roller linkage, the brake connecting rod mechanism of spinning organ.When starting, uses by the broken yarn joint the present invention, after broken yarn takes place, open the movable rack of spinning organ, movable rack blocks the eave tile pulling eave tile pull bar rotation of eave tile pull bar, the eave tile pull bar has been shored pinch roller and revolving cup braking mechanism by pinch roller linkage and brake connecting rod mechanism, make pinch roller rising tengential belt break away from the revolving cup rotating shaft, no longer be revolving cup rotation transferring power, the revolving cup braking mechanism is close to the revolving cup rotating shaft revolving cup is checked no longer rotation, the position of eave tile draw rod positions locking device locking eave tile pull bar this moment, after revolving cup stops operating the revolving cup inner chamber is cleared up, removed residual fiber and impurity; After the cleaning of revolving cup inner chamber is finished, the movable rack that closes, but the eave tile draw rod positions is still locked by eave tile draw rod positions locking device, revolving cup still can not rotate, feed to sliver to cotton roller, combing roller is carded to filament with sliver, and the fiber that the sliver head is damaged is directly siphoned away by the machine negative pressure; Through a period of time feed to sliver after, yarn and thread head is inserted revolving cup as drawing loose thread, eave tile draw rod positions locking device is removed the locking to the eave tile draw rod positions simultaneously, the rotation that resets of eave tile pull bar, no longer shore pinch roller linkage and brake connecting rod mechanism, braking mechanism descend to break away from and to unclamp the revolving cup rotating shaft, and step-down tengential belt and is close to the revolving cup rotating shaft again and drives revolving cup and rotate at a high speed under the pinch roller, cotton fiber enter revolving cup the revolving cup collection surface with draw loose thread and combine by drawing loose thread and draw spun yarn.Realized the rotation of delayed startup revolving cup by eave tile draw rod positions locking device.
As technique scheme further replenish and perfect, the present invention also comprises following additional technical feature:
