Abstract

A top pressure fine adjustment type cradle belongs to spinning machineries and relates to an improvement of an integral air bag and lever type gas pressurizing cradle pressure fine adjustment device of a ring spinning machine. The top pressure fine adjustment type cradle includes a cradle base, a cradle body, a handle, a top roller holding seat and a lever mechanism, and is characterized in that a roller (14) originally arranged on the handle is changed to be arranged on a roller carrier (4), and the roller carrier (4) drives the roller (14) to change position so as to enable a pressure transmitting crank (7) to sway properly by taking a pressure transmitting crank fulcrum pin (15) as a centre for pressure fine adjustment. Pressure fine adjustment can be performed above the cradle, so that the fine adjustment operation is more convenient, and the fixing of the cradle is firmer. Therefore, the requirements for further improving the spinning quality can be met.

Description

Top pressure cradle in fine adjustment type

Technical field the utility model belongs to spinning machinery, relates to the improvement of integral gasbag lever airload cradle pressure micromatic setting.

The stressed uniformity of background technology, stability are one of reel cage core capabilities, and the reliability that reel cage installs and fixes is the basis of pressure stability, and the reasonability of pressure fine tuning structure is to guarantee the conforming condition of plus-pressure.Existing lever airload cradle also is provided with the pressure micromatic setting in the hope of stressed uniformity.It is to implement to adjust by the last rocking arm and base (9) that is located at the reel cage back lower place and two screws between the bottom cradle seat (10).They are provided with the location structure that boss cooperates with the hole between bottom cradle seat (10) and the tubular axis (11), so can not be swung relatively.In suitably unscrewing above-mentioned two screws one and when tightening another screw, last rocking arm and base (9) will be that an amount of swing is done at the center with the center of a tubular axis (11).Because pressure transmission crank fulcrum pin (15) is fixed on the rocking arm and base (9), roller pin (16) is fixed on the handle, handle is by reel cage body handle pin (17) and reel cage body (18) hinge connection, reel cage body (18) is by reel cage seat pin (8) on the reel cage body and last rocking arm and base (9) hinge connection, and the center that just makes pressure transmission crank fulcrum pin (15) and roller pin (16) when last rocking arm and base (9) swing all produces an amount of change and makes an amount of change of plus-pressure implement that plus-pressure finely tunes.With this scheme implementation pressure fine setting following shortcoming is arranged: the one, because being located at the back lower place of reel cage, the adjustment screw make operation extremely inconvenient; The 2nd, last rocking arm and base (9) is moving at drawing plane direction generation string thereby will swing drive reel cage body (18) when fine setting, and the gripping jaw position of upper and lower roller is changed, that is to say and when improving pressure consistency, will reduce the uniformity that upper and lower roller grips jaw position; The 3rd, a tubular axis (11) can only be used round tube; The 4th, above-mentioned two screws are all used in the fixing and stressed fine setting of reel cage on a tubular axis (11), should guarantee to fix reliably consistent being difficult to of plus-pressure taken into account when practical operation, must just may reach through the repeated multiple times adjustment.

Summary of the invention is in order to overcome the deficiency of prior art scheme, the utility model provides a kind of fixing and pressure micromatic setting of reel cage that can make independent separately, it both can carry out the pressure fine setting above reel cage, can when pressure is finely tuned, not change upper and lower roller again and grip jaw position, can make a tubular axis with the polygon pipe again, to improve stressed stability, Design in Reliability scheme.

Technical solution of the present utility model is this top pressure cradle in fine adjustment type that is applied to ring spinner, comprise that rocking arm and base, reel cage body, handle, top roller grip seat, leverage, it is characterized in that: will all be arranged on two holes---hole that cooperates with reel cage body handle pin (17) and the hole that cooperates with roller pin (16) on the handle originally, change to and be separately positioned on handle body (1) and the turning rolls (4), the centre-to-centre spacing in above-mentioned two holes is become from unalterable structure can make an amount of variable structure.

When reel cage is in pressurized state, because reel cage body handle pin (17) is to be fixed on the reel cage body (18), so be immotile, turning rolls (4) is to be associated on the handle body (1) with handle body turning rolls pin (2) hinge, roller (14) is contained on the roller pin (16), when turning rolls (4) is an amount of swing of center do with handle body turning rolls pin (2), just make and take place hole that cooperates with reel cage body handle pin (17) and the pitch-row that cooperates with roller pin (16) to change this and just make and be contained in that roller pin (16) is gone up and an amount of the change taken place in right amount with the position of the contacted roller of pressure transmission crank (7) (14), thereby forcing pressure transmission crank (7) is that an amount of swing is done at the center with pressure transmission crank fulcrum pin (15), the plus-pressure of apparent reel cage will change in right amount in corresponding generation, and this finely tunes the reel cage plus-pressure with regard to realizing.

Advantage of the present utility model and good effect are to carry out the reinforcing fine setting above reel cage, can make reel cage install, adjust more convenient, more accurate, range of regulation is bigger, thereby more can guarantee stressed uniformity of reel cage and stability, a tubular axis of reel cage can also be used polygon, to grip the uniformity of jaw position higher for each upper and lower roller in the time of making simultaneously spinning again, thus the ingot difference when reducing to spin and improve the yarn count quality advantage is provided.
