Abstract

The utility model discloses a semi automatic adjustable spindle for the spinning winding machine. The semi automatic adjustable spindle is characterized in that the lock core is sheathed with an elastic lock sleeve whose shaft is opened upwards and the circumference of the lock sleeve is provided with at least three detached notch grooves. The a b section diameter of the lock core matched with the elastic lock sleeve is larger than the b c section diameter. The utility model has the advantages of simple structure, low cost, easy maintenance and long service life.

Description

Semi automatic adjustable spindle

The utility model relates to a kind of Winding spindle, uses for bobbin winder in spinning.

In " 9 ° 15 of 1332 type bobbin winder " improvement of spindle " (57 pages of " cotton textile technology " 8 or six year first phases; scientific information research institute of Ministry of Textile Industry of publisher, Textile Inst. of Shaansi Prov) literary composition a kind of Winding spindle is disclosed; be made of institutes such as spindle top, oil-containing brass, adjusting nut, compression top spring, ejector pin, flyer, top iron, flyer collar, ingot cover, stage clip, spindle, ratch, taper sheaths; its weak point is to realize the complex structure of identical functions-chucking doff paper tube-adopted; manufacturing cost height, inconvenient maintenance.

It is a kind of simple in structure that the purpose of this utility model just is to provide, long service life, and cost is low, keeps in repair the Winding spindle new product by means of manual realization degree of tightness easy to use.

Description of drawings is as follows:

Fig. 1 is semi-automatic degree of tightness spindle stereogram.

Fig. 2 is semi-automatic degree of tightness spindle structure half sectional view, and spindle 10, nut 9 and plectrum 6 do not draw.

Fig. 3 is the front view of lock core.

Realize that measure of the present utility model is: require the diameter of lock core 5 and elastic lock sleeve 4 matching part ab sections greater than bc section diameter; At the gap slot of axially offering the certain-length more than 3 or 3 of elastic lock sleeve 4 and by circumference equal dividing. Measure also has, and lock core 5 is installed on the sleeve 2, requires its front end to withstand spring 3, and during thereafter usefulness back-up ring 8 chuckings, and promotion spring 3, lock core 5 can endwisely slip along sleeve 2; Elastic lock sleeve 4 is sleeved on the lock core 5 and couples together with short slot and sleeve 2 that jackscrew 7 passes lock core 5. Also require simultaneously elastic lock sleeve 4 to be the profile of the frustum of a cone, bus is zigzag or triangle, and purpose is for firmly Firmly grasp the doff paper tube.

Fig. 1, Fig. 2, Figure 3 shows that a most preferred embodiment of the present utility model.At first according to shown in Figure 2, be press-fitted oil-containing brass 1 at the two ends of sleeve 2, and put on spring 3, make lock tube 5 put six lobe elastic lock sleeves 4 then, removable mounting is on sleeve 2 again, and block with back-up ring 8 at the rear portion, it is withdrawed under the elastic force effect, at last, with the short slot of jackscrew 7, six lobe elastic lock sleeves 4 are connected with sleeve 2 by lock core 5.We are called the iron pagoda to the assembly of above-mentioned part.If it is the iron pagoda is installed on the spindle 10 of bobbin winder, fastening with nut.Just formed the utility model.The operation principle of this utility model is: during doff, the spinner is with under the spindle plate, and plectrum 6 promotes lock core 5 and is moved to the left on sleeve 2, and spring 3 is compacted, the bc end face that this moment, six lobe elastic lock sleeves 4 rear portions were stuck in lock core 5 is in contraction state, and bobbin can easily fall.Plug new paper tube (or plastic tube) again, push spindle to operating position, plectrum 6 breaks away from lock core 5, and lock core 5 is moved right by spring 3 pressure, because of the diameter of the ab section of lock core 5 diameter, so six lobe elastic lock sleeves 4 are strutted and are in the tensioner state and tighten paper tube greater than the bc section.Six lobe elastic lock sleeves 4 are the axial thin-walled shape members of producing 6 gap slots along the circumference five equilibrium at its housing.In order to catch paper tube firmly, should be six lobe elastic lock sleeves 4 profile of the frustum of a cone, bus is made zigzag.

In the above-described embodiments, the structure of part and assembly relation are constant substantially, only change the profile of six lobe elastic lock sleeves 4, make its profile bus that becomes the frustum of a cone make triangle and just can be changed into another kind of embodiment.

Claims

1, a kind of semi-automatic degree of tightness spindle of the bobbin winder that is used to spin is studded with the sleeve 2 of oil-containing brass 1 and is sleeved on spring 3, the back-up ring 8 on the sleeve 2 and the plectrum 6 that is fastened on the spindle support is formed by two ends on the spindle 10, it is characterized in that:

A, be sleeved on lock core 5 and elastic lock sleeve 4 matching parts on the sleeve 2 ab section diameter greater than bc section diameter,

B, the elastic lock sleeve 4 that is sleeved on the lock core 5 evenly distribute at the cylinder mouth groove of axially offering 3 certain-lengths of its housing and by circumference at least.

2, according to the described semi-automatic degree of tightness spindle of claim 1, it is characterized in that: lock core 5 front ends prop up spring 3, and there are back-up ring 8 chuckings at the rear portion, compression spring 3, and lock core 5 can move axially along sleeve 2.

3,, it is characterized in that elastic lock sleeve 4 is sleeved on the lock core 5 and pass the short slot of lock core 5 and be connected with sleeve 2 with lock core 7 according to the described semi-automatic degree of tightness spindle of claim 1.

4, according to the described semi-automatic degree of tightness spindle of claim 1, it is characterized in that the outer likeness in form frustum of a cone of elastic lock sleeve 4, its bus can be made into zigzag or triangle.
