Description
" technical field "
The present invention relates to a kind of and weaving fine spining machine matching used drafter, particularly belong to a kind of three-roller mechanical type compact spinning drafting mechanism.
" background technology "
Compact spinning is a kind of novel spun yarn spinning technique that rises in Europe in the later stage nineties in last century, it is because of reducing or eliminating twist triangle zone substantially, so can reduce Yarn filoplume effectively, improve yarn strength, and yarn evenness, ABRASION RESISTANCE and outward appearance also have more significantly to be improved, and makes the quality of compact spinning be much better than the traditional ring spinning yarn.
But at present domestic and international popular several compact spinning apparatus adopt the negative inspiratory pressure principle to realize finishing for " closely " " gathering " of fiber strip mostly.Negative inspiratory pressure needs the additive decrementation electric energy, the apparatus structure complexity, and difficulty of processing is big, the manufacturing cost height, getter device easily stops up, and operation, maintaining require very high.And only several mechanical type compact spins, and also because the strip dry CV value of institute's yarn is desirable not to the utmost even deterioration to some extent, thereby does not reach desirable user mode.
" summary of the invention "
The object of the present invention is to provide a kind of novel three-roller mechanical type compact spinning drafting system, need not to realize the purpose of compact spinning under the situation that existing fine spining machine is changed in a large number.

" specific embodiment "
As shown in Figure 1, three-roller mechanical type compact spinning drafting system disclosed in this invention, the middle roller group that has the front roller group that constitutes by front upper roller (2) and preceding bottom roll (6) that is installed on the pneumatic pressurizing cradle (1), constitutes by middle top roller (9) and middle bottom roller (8), by back top roller (12) and after the rear roller group of bottom roll (11) formation, and upper leather ring (25) and following apron (24).Said structure and prior art are basic identical.
On the said structure basis, the present invention also has passive delivery beaming device, fine spining machine V-arrangement drafter and three-roller mechanical type compact and spins downside pin.
As Fig. 1, shown in Figure 5, described passive delivery beaming device comprises guide roller (5), buncher (4) and goes up alnico magnets (18) and the stop support (16) that is provided with.Beaming device connects with the reel cage head by leaf spring (3) and link (17) and obtains pressure.Buncher (4) is attached at the roller surface of preceding bottom roll (6) by alnico magnets (18), shown in Fig. 7～10, on buncher and the bottom surface that preceding bottom roll (6) roller contacts tubaeform groove (19) is arranged.As Fig. 8, shown in Figure 9, the degree of depth of the tubaeform groove of buncher (19) is 0.1～2 millimeter, and its big end is of a size of 2～18 millimeters, small end and is of a size of 0.1～3 millimeter.The raw material of making buncher are all kinds of potteries or the magnetic metal material in the nonmetallic materials.Leaf spring (3) and stop support (16) shown in Figure 11, its shape also can change according to the actual installation needs, and the general engineering technology personnel expect easily because of belonging to, so do not do too much explanation.
As shown in Figure 1 and Figure 2, the present invention is provided with between middle roller group and rear roller group and rotates press-roller device (10), constitutes described fine spining machine V-arrangement drafter.As shown in Figure 3, Figure 4, described rotation press-roller device (10) by back shaft (14) and the pressure roller (15) that is used for that back shaft is fixed in the installing rack (13) of pneumatic pressurizing cradle and is installed in the back shaft end form.Adopt rotatable the connection between pressure roller (15) and the back shaft, as bearing is installed, perhaps between is directly arranged ball or needle roller.The centre of location horizontal direction centre-to-centre spacing of the centre of location of pressure roller (15) and middle top roller (9) is 17～23 millimeters, and vertical direction centre-to-centre spacing is 6.5～12.5 millimeters.The shape of installing rack (13) can change according to the actual installation needs.
As shown in Figure 1, in following apron (24), be provided with three-roller mechanical type compact between front roller group and the middle roller group and spin downside pin (7).It is independent parts that described three-roller mechanical type compact spins downside pin, is primarily characterized in that the change of shape of cross section and installation dimension.As shown in Figure 6, its upper surface is made of a straightway (20) and a curved section, and this curved section comprises three sections circular arcs, i.e. frontal arc (21), middle arc (22) and backarc (23), for obtaining desirable effect, its arc radius is respectively frontal arc (21): 3～8 millimeters; Middle arc (22): 10～15 millimeters; Backarc (23): 25～50 millimeters.Through experiment showed, that other size of the present invention also has certain scope of application: straightway (20) length is 2.5～4.5 millimeters; The summit of curved section to the vertical height of straightway is 1.5～3 millimeters; Cross-sectional width is 20～23 millimeters; Straightway to the height of installed surface is 23～24.5 millimeters; Straightway to face height is 25 millimeters.
Three-roller mechanical type compact disclosed in this invention spins downside pin, also can be supporting with three roller ring spinning frame drawing-off reel cages, use on three roller RING SPINNING.
Three-roller mechanical type compact spinning drafting system disclosed in this invention, used novel fine spining machine V-arrangement drafter, make the length of the grip hold arc that the yarn yarn forms on the rear roller surface, be increased to 29mm by 18mm, length of floating area then reduces to 22.5mm by original 35mm, and eliminated the reverse arc of contact at middle roller jaw place, eliminate floating fiber and shifted to an earlier date the negative effect that speed change produces, make the interfibrous cohesive force of back zone yarn after drawing-off increase, the yarn that is input to the proparea is tightr, for good condition has been created in the proparea drawing-off.
The present invention has used three-roller mechanical type compact to spin downside pin in the proparea.Because its cross-section width dimension diminishes, the installation site descends, and has eliminated because of the variation of the yarn input state that front upper roller hypsokinesis that beaming device causes causes is installed.Also, pin can be visited in the past because its installation site descends, the district that reduced to swim, favourable to improving yarn evenness.Install beaming device additional in front roller group front, because drawing-off is finished, harmful effect is given birth in the dry labor of accumulation process stripes not match, the fiber head, the tail end that stretch out outside the yarn after the drawing-off are put in order, make yarn narrow down, become tight, thereby reach junction when twisting that yarn is sent into guide roller and bottom roll, reduce twist triangle zone, realize compact spinning.
