Ring throstle thread board lifting transmission device
Technical field
The invention belongs to a kind of components of textile machine, and in particular to ring throstle thread board lifting transmission device.
Background technology
In spinning process, the elevating movement of thread board is most important, it directly affects the indexs such as breakage, works as pipe
Yarn is at the small yarn stage, it is desirable that thread board does not move or small movement, and when entering meduim yarn and later stage, thread board is normal
Movement.
Thread board lifting and driving mode traditional at present is as shown in Fig. 2, when upper distributing shaft 10 moves reciprocatingly(Grade simultaneously
It rises), the first thread board gipsy sheave 11 for being fixed thereon drives distributing shaft that chain 12 and the second gipsy sheave 13 is affected to move together,
Cause the third thread board gipsy sheave 15 being fixed on lower distributing shaft 14 to rotate, chain 16, guide are affected so as to cause thread board
The movement of plate gipsy sheave group 20 and thread board elevating chain group 21, is finally completed the lifting process of thread board.Wherein, thread board is led
Dynamic chain 16 is controlled by the Wei Cha mechanisms of the compositions such as position fork 17, end cap 18, position fork shaft bearing 19, when coil is in the small yarn stage
When, thread board affects the axis pin on chain to be in the groove of position fork, and position fork is played a supporting role, when distributing shaft moves reciprocatingly
When, by position fork support angle influenced, thread board elevating chain drive thread board do small movement, when enter meduim yarn and after
When the stage, thread board affects the axis pin on chain to be detached from the groove of position fork, and position fork is ineffective, when distributing shaft moves reciprocatingly
When, thread board elevating chain drives thread board proper motion.Traditional thread board lifting and driving Zhong Weicha mechanisms are complicated, part category
More, of high cost and difficult to install, position fork is easily broken in the process of running, influences the reliability of complete machine.
Invention content
The technical problem to be solved by the present invention is to:A kind of ring throstle thread board lifting transmission device is provided, is passed through
The eccentric gipsy sheave of optimization design substitutes complicated position fork control mechanism, fundamentally solves the problems, such as position fork fracture.
Technical scheme of the present invention:Ring throstle thread board lifting transmission device, it includes rack, upper distributing shaft 1,
One thread board gipsy sheave 3, distributing shaft affect chain 4, eccentric gipsy sheave 5, lower distributing shaft 2, the second thread board gipsy sheave 6, guide
Plate affects chain 7, thread board gipsy sheave group 8 and thread board elevating chain group 9, and upper distributing shaft 1 is horizontally installed on upper rack, under
Distributing shaft 2 is horizontally installed on frame lower, and upper distributing shaft 1 is arranged with lower distributing shaft 2 in rack the same side, hoisting mechanism setting
In the rack other side, the setting of the first thread board gipsy sheave 3 is arranged in 1 one end of upper distributing shaft, eccentric gipsy sheave 5 in lower distributing shaft 2
One end, the first thread board gipsy sheave 3 affect chain 4 to connect with eccentric gipsy sheave 5 by distributing shaft, the second thread board gipsy sheave 6
In 2 other end of lower distributing shaft, thread board gipsy sheave group 8 is arranged on upper distributing shaft 1 for setting, the second thread board gipsy sheave 6 with lead
Yarn plate gipsy sheave group 8 affects chain 7 to connect by thread board, and thread board elevating chain group 9 is arranged in thread board gipsy sheave group 8
On.
Further, eccentric chain-wheel cunning 5 and the junction setting of lower distributing shaft 2 link 5 center of skidding in bias
Side.
Further, the thread board gipsy sheave group is made of three identical thread board gipsy sheaves, thread board lifting
Chain group 9 is made of the first thread board elevating chain and the second thread board elevating chain, and the second thread board pulley 6 passes through thread board
Chain 7 is affected to be connect with the intermediate thread board gipsy sheave of thread board gipsy sheave group 8, the thread board of 8 both sides of thread board gipsy sheave group
Gipsy sheave is connect by the first thread board elevating chain with the second thread board elevating chain with hoisting mechanism.
The advantageous effect of the present invention compared with prior art:This ring throstle thread board lifting transmission device, with optimization
The eccentric gipsy sheave of design, substitute complicated position fork control mechanism reduces part category under the premise of function is identical, side
Just it installs, while reducing the cost of complete machine, fundamentally solve the problems, such as position fork fracture, improve the reliability of complete machine.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention;
Fig. 2 is original thread board lifting transmission device structural schematic diagram.
Specific implementation mode
As shown in Figure 1, 2, ring throstle thread board lifting transmission device, it includes rack, upper distributing shaft 1, first leads
Yarn plate gipsy sheave 3, distributing shaft affect chain 4, eccentric gipsy sheave 5, lower distributing shaft 2, the second thread board gipsy sheave 6, thread board to lead
Dynamic chain 7, thread board gipsy sheave group 8 and thread board elevating chain group 9, it is characterized in that upper distributing shaft 1 is horizontally installed in rack
Portion, lower distributing shaft 2 are horizontally installed on frame lower, and upper distributing shaft 1 is arranged with lower distributing shaft 2 in rack the same side, hoisting mechanism
Setting is arranged in 1 one end of upper distributing shaft, eccentric gipsy sheave 5 in lower distribution in the rack other side, the setting of the first thread board gipsy sheave 3
2 one end of axis, the first thread board gipsy sheave 3 affect chain 4 to connect with eccentric gipsy sheave 5 by distributing shaft, and eccentric chain-wheel slides 5 under
The side at 5 center of eccentric link skidding is arranged in the junction of distributing shaft 2, and for coil at the small yarn stage, distributing shaft affects chain
Close to bias gipsy sheave remote location, when distributing shaft moves reciprocatingly(Grade rises simultaneously), distributing shaft affects chain-driving inclined
Heart gipsy sheave does small movements so that thread board elevating chain drives thread board that very small displacement occurs, when coil is in meduim yarn
And when later stage, distributing shaft affects chain to move closer to eccentric gipsy sheave proximal point, and distributing shaft affects chain-driving inclined
Heart gipsy sheave does proper motion so that thread board elevating chain drives thread board can proper motion.Second thread board gipsy sheave 6 is set
It sets in 2 other end of lower distributing shaft, thread board gipsy sheave group 8 is arranged on upper distributing shaft 1, the second thread board gipsy sheave 6 and guide
Plate gipsy sheave group 8 affects chain 7 to connect by thread board, and thread board elevating chain group 9 is arranged in thread board gipsy sheave group 8.
Wherein, thread board gipsy sheave group is made of three identical thread board gipsy sheaves, and thread board elevating chain group 9 is by the first thread board
Elevating chain and the second thread board elevating chain composition, the second thread board pulley 6 affect chain 7 and thread board chain by thread board
The intermediate thread board gipsy sheave of pulley blocks 8 connects, and the thread board gipsy sheave of 8 both sides of thread board gipsy sheave group passes through the first thread board
Elevating chain is connect with the second thread board elevating chain with hoisting mechanism.By the interaction between each part, it is finally completed guide
The lifting process of plate.
