Description
Technical field
This utility model belongs to technical field of textile machine, and especially pneumatic with the one yarn roller automatic linkage device that draws has
Close.
Background technology
In existing spinning machine, when spinning, the periphery and the delivery roller periphery that draw yarn roller abut
Thread grip is lived, draws yarn roller and rotarily drive delivery roller rotating Vortex, and yarn is pulled out, then driven by Wound-up roller
Winding yarn held by dynamic yarn collet chuck, when broken yarn, needs to draw yarn roller away from delivery roller so that roller stops the rotation, convenient
Workman's joint.At present electric magnet is the important component part that yarn roller is drawn in linkage, for control draw yarn roller and delivery roller it
Between whether contact, currently available technology to draw yarn roller electromagnet structure more complicated, poor reliability, in the case of normal spinning by
In being chronically at "on" position, causing self-heating, energy consumption is high, and service life is short；And existing draw yarn roller at joint or
Being directly to contact with delivery roller during shutdown, it is low to draw yarn roller case hardness, will produce impression for a long time, affect yarn matter
Amount.
Utility model content
The purpose of this utility model is intended to overcome the existing linked manner energy consumption height drawing yarn roller, short lacking in service life
Fall into, it is provided that a kind of energy consumption is low, the pneumatic of simple in construction, length in service life draws yarn roller automatic linkage device.
To this end, this utility model is by the following technical solutions: one is pneumatic draws yarn roller automatic linkage device, including installing
Plate, drawing yarn roller, rubber roll shaft, roller support, delivery roller, roller shaft, rotary shaft and cylinder, delivery roller passes through bearings
Being set on described roller shaft, roller shaft and rotary shaft are all fixedly installed in described installing plate and both are parallel, roller
Support includes installing arm and driving arm, and the one end installing arm and the one end driving arm are all fixing with described rotary shaft to be connected, and makes
Installing arm and drive that arm is at an angle is relatively fixed, install arm and drive arm with rotary shaft rotary oscillation, described draws yarn roller
Be set on described rubber roll shaft by bearings, rubber roll shaft and described installation arm be mutually perpendicular to and with the other end installing arm
Fixing connection, the periphery drawing yarn roller is corresponding with the periphery of described delivery roller, and the other end of described driving arm is with described
Cylinder piston rod be flexibly connected by bearing pin, the inner chamber of cylinder block is provided with a spring, one end of this spring is resisted against
The bottom of described cylinder piston, the spring other end is resisted against the bottom of described cylinder block inner chamber, has the piston of cylinder
Certain elastic force, the cylinder body of cylinder is installed on described installing plate.
As supplementing technique scheme and perfect, this utility model also includes techniques below feature.
The bottom of described cylinder block inner chamber is provided with a spring fairlead, and spring fairlead is plugged in described spring
In central through hole, spring is played certain guide effect.
Described spring is compression spring.
When normally spinning, cylinder does not works, in cylinder piston under the action of the spring to piston produce one top power,
Make piston rod in the state of stretching out, i.e. make to draw yarn roller and contact with delivery roller by driving arm and installation arm and have certain
Pressure；When shutting down or during joint, cylinder energising work, the elastic force of piston overpowers spring moves to the bottom of cylinder inner cavity, makes
Piston rod indentation campaign, drives and drives arm and install arm rotation centered by rotary shaft, and installation arm straps is dynamic draws yarn roller away from drawing
Leno draws, and cylinder can keep this state under the influence of air pressure until spinning machine normally spins starts.
This utility model can reach following beneficial effect: this utility model is shutting down or during cylinder energising work during joint
Between short, energy consumption is low, simple in construction, easy to maintenance, and service life is long, it is ensured that yarn qualities.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described in detail.
As it is shown in figure 1, this utility model include installing plate 6, draw yarn roller 2, rubber roll shaft, roller support, delivery roller 1,
Roller shaft, rotary shaft 4 and cylinder 9, delivery roller 1 is set on described roller shaft by bearings, roller shaft and rotation
Axle 4 is all fixedly installed in described installing plate 6 and both are parallel, and roller support includes installing arm 3 and driving arm 5, installs arm 3
One end and drive one end of arm 5 all to fix with described rotary shaft 4 to be connected, make installation arm 3 at an angle relative with driving arm 5
Fixing, arm 3 to be installed and drives arm 5 with rotary shaft 4 rotary oscillation, the described yarn roller 2 that draws is set in described by bearings
Rubber roll shaft on, rubber roll shaft is mutually perpendicular to described installation arm 3 and fixing with the other end installing arm 3 is connected, and draws yarn roller 2
Periphery is corresponding with the periphery of described delivery roller 1, and the other end of described driving arm 5 passes through with the piston rod 8 of described cylinder 9
Bearing pin 7 is flexibly connected, and is provided with compression spring 11 and a spring fairlead 12 in the inner chamber of cylinder 9 cylinder body, this spring 11
One end is resisted against the bottom of described cylinder 9 piston 10, and spring 11 other end is resisted against the bottom of described cylinder 9 inner chamber of cylinder block,
The piston 10 of cylinder 9 is had certain elastic force, and spring fairlead 12 is plugged in described spring 11 central through hole, and spring is led
Axial length no more than spring 11 to set 12 is compressed into length the most in short-term, and the cylinder base of cylinder 9 is movably installed in described
Installing plate 6 on.
When normally spinning, cylinder 9 does not works, in cylinder 9 piston 10 under the effect of spring 11, piston 10 is produced
A raw top power, makes piston rod 8 in the state of stretching out, is i.e. made to draw yarn roller 2 connected with delivery roller 1 by driving arm 5 and installation arm 3
Touch and there is certain pressure；When shutting down or during joint, cylinder 9 is energized work, and piston 10 overcomes the elastic force of spring 11 to gas
The bottom motion of cylinder 9 inner chamber, makes piston rod 8 indentation campaign, drives and drives arm 5 and install arm 3 rotation centered by rotary shaft 4,
Installing arm 3 to drive and draw yarn roller 2 away from delivery roller 1, cylinder 9 can keep this state under the influence of air pressure until spinning
Machine normally spins and starts.
