Description

Double gear long guide colume rereeling reel

The utility model relates to a kind of carrier that installs around raw silk in order to filature industry raw silk rereeling operation.

Rereeling is the one procedure that filature is produced, and this operation installs around Chou Chu And from silk cocoon little

On raw silk install around greatly again

On make the raw silk sheet.Because from little

Rereeling is to big

On raw silk be moist, raw silk is greatly

Can produce very big convergent force after the last drying, the raw silk lock ring is greatly

On, make big

Bear the radial pressure of tons of.Of the prior art big All adopt the double-shift type structure of making strut with steel pipe, this form is: initial and end and middle part at rotating shaft respectively are installed with one grade of support member of being made up of isometric steel strut of the six roots of sensation and strut socket, strut socket is installed on the rotating shaft, and the strut lower end is inserted in the strut jack of strut socket.Six roots of sensation strut evenly is arranged on 360 ° of circumference radially with in the cross section that is in perpendicular to rotating shaft.The third gear strut is vertically lined up six row, and the top of each row is all connecting a wooden frame, forms one greatly

, raw silk installs around greatly

The outside of wooden frame.For can be with lock ring greatly

On raw silk take off (promptly fall silk), big

On six row struts in have one row can stretch, be called active strut.When greatly

On install around after the full raw silk, with active strut indentation, reduce big

Outside circumference, loosen raw silk Juan And and take off.The active strut of these row adopts guide pillar, guide pin bushing structure, the top of guide pillar connects wooden frame, the other end is inserted in the guide pin bushing, and guide pillar can stretch in guide pin bushing, in the proper site of guide pillar guide pin bushing one blocking device is set, pull out guide pillar when the blocking device locking, active strut is just in time isometric with other each row strut, when needs fall thread, pulls all-or-nothing piece, opening closure allows among the guide pillar indentation guide pin bushing.The structure of active strut blocking device is: a reed is installed on the guide pillar, and a centering block is installed on the reed next door, and an all-or-nothing piece is installed on the guide pin bushing, outwards pull out when guide pillar, reed ejects centering block, and centering block lower surface card is pressed on the all-or-nothing piece, form locking, prevent that guide pillar from moving in guide pin bushing.When falling thread, because raw silk shrinks the pressure that strut is produced, increased the frictional force on centering block lower surface and the all-or-nothing piece periphery, as long as therefore pull the all-or-nothing piece rotation, just can drive centering block compressing reed and swing in guide pillar, when centering block swung to certain position, the centering block lower surface moved to the all-or-nothing piece inboard, under the effect of radial pressure, guide pillar just goes in the indentation guide pin bushing.Above-mentioned of the prior art big Be widely used on the rereeling machine of filature factory.This big

Following weak point is still arranged in use:

1. because of being steel, be again third gear, structural member is many, and weight is bigger, so operator's labour intensity is bigger.

2. strut and strut socket are not integrative-structures, and be therefore firm inadequately, makes big

Be unable to undergo the impact of axial force, fragile.

3. active strut is made up of third gear (root), and the third gear blocking mechanism is difficult to synchronous unlatching when falling thread, one of two, locking often takes place to open, or open one, and the phenomenon that locking is two causes the wooden frame unbalance stress and fractures.

4. active strut is over against rotating shaft, and the retraction of guide pillar is subjected to the obstruction of rotating shaft, and the retraction amount is too little, and the silk that falls still feels convenient inadequately.

5. the blocking device of active strut is arranged on the middle and upper part (near the wooden frame place) of strut, causes big

Quality is unbalanced, and it is far away that barycenter departs from axis of rotation, has a strong impact on big Spin balancing.

Task of the present utility model is that design a kind ofly can overcome the above-mentioned shortcoming of prior art, and performance has the novel big of bigger improvement

Fig. 1 is big in the prior art Structure chart.

Fig. 2 is the vertical view of Fig. 1.

Fig. 3 is big in the prior art The structure chart of active strut.

Fig. 4 is a structure chart of the present utility model.

Fig. 5 is the vertical view (broken section) of Fig. 4.

Fig. 6 is the active strut blocking device of a utility model structure chart.

Below in conjunction with accompanying drawing the technical solution of the utility model is described.

The utility model is by driving-disc 1, rotating shaft 2, fixedly active strut, wooden frame 6, all-or-nothing piece 7, bolt 8, screw 9, centering block 10, reed 11 and the edge formed of strut 3, guide pin bushing 4 and guide pillar 5 12 formed.The utility model adopts second gear formula structure, and promptly one grade of support member is respectively installed in the upper and lower part of rotating shaft 2, saves middle one grade than prior art, and making can reduce structural member morely like this, alleviates big

Weight ， And and blocking device also only need two, improved the uniformity of locking and breakdown action greatly, the shortcoming of the wooden frame of having avoided fractureing because of switching motion is inconsistent.Adopt after the second gear version, can suitably strengthen wooden frame 6 height (promptly improving the module of anti-bending section of wooden frame), to strengthen bearing capacity.Five of each grade of the utility model support member fixedly the guide pin bushing 4 of strut 3 and a root for activating collaterals strut adopt overall structures, make circular hole in this whole centre, in order to install with rotating shaft 2.Fixedly strut 3 can adopt circle, ellipse, rectangle, multiple shaped cross such as cross.In order to strengthen the stroke of active strut, the direction of guide pin bushing 4 departs from rotating shaft 2, is not subjected to the obstruction of rotating shaft 2 when guide pillar 5 is stretched in guide pin bushing 4, and the flexible scope of guide pillar 5 is expanded to greatly

Beyond the radius, strengthened the retraction amount of guide pillar 5, made silk very convenient.The blocking device of the active strut of the utility model is arranged on and the be relatively fixed root of strut 3 of guide pin bushing 4, near rotating shaft 2, has reduced big Eccentricity has improved the balance of rotating.Blocking device is also made a big improvement, and centering block 10 and reed 11 are installed in and the be relatively fixed root of strut 3 of guide pin bushing 4, and there is cancave cambered surface on a centering block 10 upper ends, and all-or-nothing piece 7 is installed in the cambered surface.The inclined-plane, lower end of guide pillar 5 roots edge 12 is stuck on the all-or-nothing piece 7, as relative sliding surface.The screw 9 of edge 12 lower end is in order to restriction guide pillar 5 length of pulling out, and prevents that guide pillar 5 from extracting dislocation out from guide pin bushing 4.

The overall structure support member of the utility model embodiment adopts aluminum casting, and fixedly strut 3 has adopted the cross section shape.The installation method of support member and rotating shaft 2 is, on rotating shaft 2, moveable support screws bolt 8 behind certain position, support member firmly is clamped on the rotating shaft 2 with the circle hole sleeve at support member center.The guide pillar 5 of present embodiment adopt metal pipe material ， And in its lower end fixedly assembly unit inlay 12.The lower end of the lower end of reed 11 and centering block 10 is riveted together.

The utility model except can overcoming 5 shortcomings enumerating previously, also has following 2 benefits compared with prior art at least:

1. increase the length of guide pillar 5, that is increased the length of guide pillar 5 in guide pin bushing 4, therefore can limit the free degree of guide pillar 5 effectively, strengthened active strut steadiness.

2. centering block 10 and reed 11 are not arranged on the guide pillar 5, have therefore avoided fluting on guide pillar 5, have improved the mechanical strength of guide pillar 5.
