Description
Technical field
The present invention relates to the textile industry field, refer to that specifically a kind of ring throstle reduces the spinning apparatus of broken end of driving that doffs.
there are 200,000,000 spindles in the tradition ring throstle whole world, China now has 1.2 hundred million spindles, the tradition ring throstle is owing to being subject to twisting the impact that in mechanism, twist transmission weakens gradually, causing twist triangle zone is the weak twist zone, twist triangle zone spinning brute force is lower, if improve spinning speed or spinning low-twist yarn, broken end can increase, the problem of the relevant rear driving broken end that doffs, the large serious problems of one in textile technology, be not resolved for a long time, when doffing rear driving, due to the thread board upset, it is more that sliver is pulled out elongation, sliver is lax makes the twist of twist triangle zone disappear fully, as shown in Figure 5, twizzle position when 13a spun for the beginning, twizzle position when 13b is full yarn, 13c is the twizzle position after overturning.Yarn after the twizzle upset is L1 and L2 two parts, is tensioning state; After twizzle resetted, the length of yarn L3 was relaxed state less than L1+L2.L3=163mm in Fig. 5, L1=105mm, L2=80mm, L1+L2=185mm.When again driving, the twist of yarn fails in time to transmit to put in place, very easily breaks end, and causes a large amount of significant loss and increase operative employee's workload, and yarn quality also is difficult to guarantee.
The combined type friction twisting apparatus of a kind of ring throstle that the 201110335819X Chinese patent application proposes, to undergo technological transformation on existing fine spining machine, its advantage is to improve the twist of twist triangle zone, the spinning brute force is improved, and spinning speed can further improve, still, broken end problem when doffing rear drive, do not solve, little when large when another defective of this patent application technology is friction plate to the friction force of sliver, and constantly change.the false twisting DeGrain of too small friction force to sliver, excessive friction force is to the sliver scratch, filoplume increases, its reason is along with twizzle moves up and down, the angle of contact size of sliver on friction plate changes, when twizzle is displaced downwardly to extreme lower position, the angle of contact of sliver on friction plate is maximum, friction force is also maximum, when twizzle rises to the extreme higher position, the angle of contact of sliver on friction plate is minimum, friction force is also minimum, change at random due to friction force, cause the sliver quality in same cop there are differences, also there is simultaneously difference between ingot.
Summary of the invention
The object of the present invention is to provide a kind of defective that can overcome in the above-mentioned background technology, effectively control friction force, the ring throstle that reduces the rear driving broken end that doffs reduces the spinning apparatus of the driving broken end that doffs.
The present invention realizes by following technical measures, the ring throstle that namely provides reduces the spinning apparatus of driving to break end that doffs and is characterised in that, at the front roller nip of existing ring throstle to the spinning section of twizzle, the square-section batten of an installation use is set along the length direction of ring throstle, the square-section batten is fixed by the car panel of installation foot and ring throstle, and each Yarn-spinning spindle correspondence arranges a cover frictional engagement part, a cover press pin conjunction, a cover upset twizzle conjunction;
Every suit frictional engagement part is comprised of a mandrel, a duplex friction pulley, two bearings again, a duplex friction pulley is arranged on bearing, bearing is arranged on mandrel, mandrel is fixed on the batten of described square-section, the duplex friction pulley is by the transmission of two circular cross-section driving belts, and driving belt is driven by the drive motor on the car panel that is arranged on the ring spindle yarn locomotive head;
Every suit press pin conjunction is comprised of a press pin, a moving block, a mandrel, a balancing weight again, press pin be vertically mounted on duplex friction pulley cylindrical position and placed in the middle between, there is convex shoulder the press pin below, the press pin other end is fixed on moving block, balancing weight is fixed on press pin, moving block is enclosed within on mandrel, and mandrel is fixed on the batten of described square-section;
Every suit upset twizzle conjunction is comprised of a twizzle, a swinging block, a screw, a spring, a connecting plate, an installation foot again, twizzle is fixed on swinging block, swinging block is enclosed within on screw, spring housing is on screw, a spacer pin is fixed on swinging block, and screw is fixed on connecting plate, and an alignment pin is fixed on connecting plate, connecting plate is fixed on installation foot, and installation foot is fixed on the batten of described square-section.
Be placed between duplex friction pulley cylindrical end face, press pin, press pin convex shoulder three by the twisting sliver.
Described balancing weight can move left and right on press pin, the fine setting plus-pressure.
When stopping when doffing, press pin continues pressure holding on sliver, sliver is rotated and move.
Described upset twizzle is the swing type structure.
The upset twizzle has increased the angle of contact of sliver on friction pulley when doffing upset, play simultaneously the sliver effect that grips.
The present invention has following technical advantage, adopt single duplex friction pulley and press pin structure, simple in structure, can effectively control friction force, can regulate the minimized friction active force for different product, avoid the excessive scratch to sliver, reduce the generation of filoplume, when stopping when doffing, press pin continues the pressure holding sliver, make self-friction take turns to the sliver of front roller nip and keep original high twist state, the broken end phenomenon when avoiding again driving; Adopt upset to lead hook knot structure, can make the angle of contact of sliver on friction pulley remain constant, can keep the uniformity consistency of friction force; Doff when stopping, due to the twizzle upset, increased equally the grasping force to sliver.
