Description
Technical field
The present invention relates to field of textile industry, specifically refer to that a kind of ring throstle reduces the spinning apparatus doffing and drive to break end.
There are 200,000,000 spindles in the tradition ring throstle whole world, China now has 1.2 hundred million spindles, tradition ring throstle is owing to being subject to twisting the impact that in mechanism, yarn twist unevenness weakens gradually, twist triangle zone is caused to be weak twist region, twist triangle zone spinning brute force is lower, if improve spinning speed or spinning low-twist yarn, broken end can increase, the problem breaked end about driving after doffing, the large serious problems of one in textile technology, be not resolved for a long time, whenever driving after doffing, due to thread board upset, sliver pull-out is extended more, sliver relaxes and the twist of twist triangle zone is disappeared completely, as shown in Figure 5, 13a is the twizzle position of beginning when spinning, twizzle position when 13b is full yarn, 13c is the twizzle position after upset.Yarn after twizzle upset is L1 and L2 two parts, in tensioning state; After twizzle resets, the length of yarn L3 is less than L1+L2, in relaxed state.L3=163mm, L1=105mm, L2=80mm, L1+L2=185mm in Fig. 5.When again driving, the twist of yarn fails to transmit in time to put in place, very easily breaks end, and causes the workload of a large amount of significant loss and increase operative employee, and yarn quality is also difficult to ensure.
The combined type friction twisting apparatus of a kind of ring throstle that 201110335819X Chinese patent application proposes, undergo technological transformation on existing fine spining machine, its advantage to improve the twist of twist triangle zone, spinning brute force is improved, and spinning speed can further improve, but, for broken end problem when driving after doffing, do not solve, little time large when another defect of this patent application technology is the friction force of friction plate to sliver, and constantly change.Too small friction force is to the false twisting DeGrain of sliver, excessive friction force is to 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 extreme higher position, the angle of contact of sliver on friction plate is minimum, friction force is also minimum, due to the change at random of friction force, the sliver quality in same cop is caused to there are differences, also there is difference between ingot simultaneously.
Summary of the invention
The object of the present invention is to provide a kind of defect that can overcome in above-mentioned background technology, effectively control friction force, reduce the ring throstle of driving to break end after doffing and reduce the spinning apparatus doffing and drive to break end.
The present invention is realized by following technical measures, namely the feature that provided ring throstle reduces the spinning apparatus of the driving broken end that doffs is, at the front roller nip of existing ring throstle in the spinning section of twizzle, length direction along ring throstle arranges a square-section batten installed, square-section batten is fixed by the car panel of installation foot and ring throstle, and each Yarn-spinning spindle correspondence arranges a set of friction couplings, a set of press pin conjunction, a set of upset twizzle conjunction;
Every suit friction couplings is made up of a mandrel, 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, duplex friction pulley is by the transmission of two circular cross-section driving belts, and driving belt is driven by the drive motor be arranged on the car panel of ring spindle yarn locomotive head;
Every suit press pin conjunction is made up of a press pin, moving block, mandrel, one piece of balancing weight again, press pin be vertically mounted on duplex friction pulley cylindrical position and placed in the middle between, convex shoulder is had below press pin, the press pin other end is fixed on moving block, balancing weight is fixed in press pin, moving block is enclosed within mandrel, and mandrel is fixed on the batten of described square-section;
Every suit upset twizzle conjunction is made up of a twizzle, swinging block, screw, spring, one piece of connecting plate, installation foot again, twizzle is fixed on swinging block, swinging block is enclosed within 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 described square-section batten.
Be placed between duplex friction pulley exterior dome surface, press pin, press pin convex shoulder three by twisting sliver.
Described balancing weight can move left and right in press pin, fine setting plus-pressure.
When stopping when doffing, press pin continues pressure holding on sliver, does not make sliver rotate and moves.
Described upset twizzle is swing type structure.
Upset twizzle, when doffing upset, increases the angle of contact of sliver on friction pulley, plays simultaneously and grips sliver effect.
The present invention has following technical advantage, adopt single duplex friction pulley and press pin structure, structure is simple, effectively can control friction force, can regulate 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 pressure holding sliver, make self-friction wheel keep original high twist state to the sliver of front roller nip, avoid breakage phenomena when again driving; Adopt upset twizzle structure, the angle of contact of sliver on friction pulley can be made to remain constant, the uniformity consistency of friction force can be kept; Doff stop time, due to twizzle upset, add the grasping force to sliver equally.

Detailed description of the invention
The sliver exported from front roller 26 jaw is by duplex friction pulley 3, and be placed between the surface of friction pulley cylindrical and press pin 6, press pin convex shoulder 22 three, then twizzle 13 is introduced, finally be wound on spool 27, during spinning z twist yarn, duplex friction pulley 3 rotates clockwise, sliver is subject to the acting in conjunction of friction pulley cylindrical, press pin 6, press pin convex shoulder 22, sliver is rotated counterclockwise, along with the increase of press pin pressurization, friction force increases, and the sliver twist of twist triangle zone also just increases; When stopping when doffing, friction pulley stops operating, but the sliver on duplex friction pulley 3 outer round surface continues by press pin 6 pressure holding, makes the sliver of duplex friction pulley 3 to front roller 26 jaw keep original high twist state, when again driving, sliver can not break end.
After adopting this invention technology, compared with traditional ring spinning, the twist of twist triangle zone can be improved, can further improve spinning speed, successfully solving a difficult problem for the driving broken end that doffs, decreasing the workload of significant loss and spinner.Compared with 201110335819X patent application, can effectively control friction force size, and can keep uniformity, avoid the excessive scratch to sliver, resultant yarn filoplume obviously reduces.
