Draw roll assemblies for fly frame and fly frame

Technical field

The disclosure relates generally to field of textile machinery.The disclosure is especially but not exclusively to fly frame.The disclosure enter one The embodiment of step discloses the draw roll assemblies with driving structure for fly frame.

Background technology

In textile industry, fly frame (roving frame machine) is commercially referred to as fly frame (fly ) or roving frame (speed frame) frame.Fly frame is used for for feeding sliver making coiling body.Sliver is previous draft machine The result product of tool (usually drawing frame).It is stored in bar cylinder from the sliver of drawing frame transmission, and send in follow-up roving frame, For being processed further.

Generally, multiple such bar cylinders are installed in the lower section of the tub of roving frame, feed sliver through tub deflector roll The drafting unit of roving frame.Here, by applying drawing-off, the linear density of feeding sliver can be reduced to aequum, and feeds Enter sliver and be converted to the fiber band less than its diameter.After drawing-off, fiber band is carried out with false twisting (false twist), fiber band Continue through the false twisting machine of rove device.This rove device is normally rotated with the speed more than 1200rpm.Main shaft and rove device Transmission associated, main shaft support is used for being wound around the blank pipe of twisted fibers band (twisted fibre band).Twisted fibers band logical It is commonly referred to as rove, whole coiling body is referred to as reeling roving body or flyer bobbin.This flyer bobbin is the feeding of follow-up ring throstle Material, wherein, rove is converted to yarn.

Traditionally, weaving fly frame includes drawing-off structure, before feeding yarn strip material is converted to rove, described drawing-off knot Structure carries out a certain amount of drawing-off to it.Conventional drawing-off structure generally comprises four times draw roll on Three Up Three Down or four, in fly frame These draw roll be arranged so that drawing-off structure include along machine whole length extend three or four row's rollers, these draw roll By spaced bearings.These rollers of drawing-off structure are by being connected with each other in end by motor-driven gear train.Right In the drawing-off structure with four lower rolls on four, from the point of view of the front of machine row, the 3rd draw roll is with the speed higher than the 4th draw roll Degree rotation.Second draw roll is with the speed rotation higher than the 3rd draw roll.First draw roll, also referred to as transfer roller or preliminary roller, With the speed rotation higher than the second draw roll.The ratio of one draw roll rotating speed with respect to previous draw roll is referred to as " drawing-off Multiple ", plays an important role.For dissimilar and number fiber, the selection of drafting multiple is different.

In order to improve the productivity ratio of fly frame, need to arrange the main shaft of substantial amounts of such as 200 or more.Due to main shaft number The increase of amount, fly frame planted agent arranges the longer draw roll of length.However, the increase of draw roll length is by the driving to draw roll Structure brings some challenges.With the increase of draw roll length, driving structure must provide high torsion in the whole length along roller Turn power distribution, to facilitate drawing-off, especially when processing staple fibre and resistance to drawn fiber, such as Modal, acrylon etc..In conventional crude In yarn machine, draw roll is connected with each other in end by gear train and motor.However, this structure is for entirely long along draw roll High twisting resistance distribution on degree is infeasible.For this reason, final roving yarn quality changes, and leads to thick after drawing-off Yarn some places thickness some places are thin.And, the twisting resistance deficiency in draw roll may cause the weight in draw roll and bearing Load and vibration, reduce roving yarn quality further.The further drawback of this routine draw roll assemblies is probably suffered height on roller Twisting resistance causes the excessive distortion of roller.The torsion resistance that these draw roll are shown changes from drive end to free end.This is final The damage of one or more draw roll will be led to.Further, since generation torsional vibrations, especially processing staple fibre and resistance to leading During stretching fiber, the quality of final rove will be impacted.

According to discussed above it is necessary to develop a kind of draw roll assemblies of fly frame, to overcome said one or multiple office Sex-limited.
