Description

Eccentricity pressure fine adjustment type reel cage

Technical field the invention belongs to spinning machinery, relates to the improvement of lever airload cradle pressure fine-adjustment device.

Background technology is present, and known lever airload cradle has many good qualities, and implements but its fixing and plus-pressure fine setting on a tubular axis (9) shares a cover mechanism basically.This often is difficult to accomplish to put in place simultaneously because mutually interfering when practical operation, must just may reach through repeated multiple times adjustment.Adjust the large obstacle that hell to pay becomes the further popularization of this type of reel cage owing to install.A kind of patent No. several years ago occurs and be 200620050169.9 reel cage, it sets up a cover pressure micro-adjusting mechanism in reel cage, make the fixing of reel cage and pressure fine setting separately independent mutually noninterfere solve above-mentioned shortcoming, this is a much progress.Above-mentioned patented technology changes pressure hook fulcrum pin into cam pin this scheme by straight pin and realizes the pressure fine setting.But still exist range of regulation large not with this scheme, cam pin will with vibration before and after the pressure hook, cause reel cage new destabilizing factor to occur during pressure regulation.Owing to these reasons, above-mentioned patented product is failed to obtain customer acceptance and is withdrawn from the market.

Summary of the invention is in order to keep the advantage of above-mentioned patent, can overcome its deficiency again, the invention provides a kind of also can make the fixing and plus-pressure fine setting of reel cage on tubular axis (9) separately independence, mutually noninterfere, fixing more reliable quicker, range of regulation is larger and front and back vibration, Pendulum Weighting Arm System power is more stable, more convenient operation is more practical design can not appear in pressure hook (5) substantially.

Technical solution of the present invention is this ring spinner eccentricity pressure fine adjustment type reel cage that is applied to, comprise by rocking arm and base (1), reel cage body (2), handle (4), four connecting bar locking mechanisms and top roller holding mechanism that pressure hook (5) forms, pressure hook fulcrum pin (6), it is characterized in that: set up eccentric shaft (8) and excessive plate (7) at rocking arm and base (1), eccentric shaft (8) is contained on the rocking arm and base (1), excessively plate (7) is enclosed within on the eccentric shaft (8), and pressure hook fulcrum pin (6) is contained on the excessive plate (7).Just can change the position of the excessive plate (7) that is enclosed within on the eccentric shaft (8) by the angular position that changes eccentric shaft (8), also changed simultaneously the position of the pressure hook fulcrum pin (6) that is contained on the excessive plate (7), because pressure hook fulcrum pin (6) is a fulcrum in the four connecting bar locking mechanisms, change the position of this pin, making the distance of the relevant fulcrum of retaining mechanism produce change, is that the pressure fine setting makes whole each reel cage of spinning machine all guarantee the purpose that pressure is consistent thereby reach the single reel cage pressure size of change.

In order to make pressure hook (5) when pressure is finely tuned, substantially not produce front and back vibration phenomenon, can slotted hole (10) or elongated slot (20) (opening is made in the slotted hole upper end then become elongated slot) be set in rocking arm and base (1), cooperate with pressure hook fulcrum pin (6), make eccentric shaft (8) when rotating and pressure hook fulcrum pin can only move up and down along slotted hole (10) or elongated slot (20).In order to improve the stressing conditions of slotted hole (10), elongated slot (20), can be designed to the plane in two ends and slotted hole (10), elongated slot (20) junction of pressure hook fulcrum pin (6), to strengthen faying face.Certain above-mentioned slotted hole (10), elongated slot (20) also can be located on the excessive plate (7), again rocking arm and base (1) arrange boss be mated also can play make pressure hook (5) when pressure is finely tuned substantially not before and after vibration.

Excessively the another kind of structure of plate (7) is excessive plate metapore (11) is set in its back-end and cooperates with pin (12), at this moment during eccentric rotation axis (8), excessive strip pressure hook fulcrum pin (6) and pressure hook (5) is done to swing in right amount centered by pin (12) (at this moment on the rocking arm and base (1) slotted hole (10) needn't be set, elongated slot (20)), pin (12) is larger with the centre-to-centre spacing of pressure hook fulcrum pin (6) because the pendulum amount of excessive plate is very little, so the front and back string quantity of motion of pressure hook (5) was very little when pressure was finely tuned.Above-mentioned pin (12) also can be exactly that reel cage body rocking arm and base cuts with scissors sell through joint efforts (3).Excessively the structure of plate (7) is not limited to above-mentioned two kinds, can be diversified.

Eccentric shaft (8) is after pressure fine setting puts in place, and its angular position can not change, otherwise Pendulum Weighting Arm System power will change, and therefore at least a kind of anti-loose structure should be set to eccentric shaft (8).Anti-loose structure can be diversified, as at eccentric shaft (8) internal thread being set or external screw thread is fixed on the rocking arm and base (1) with screw or nut again.Also can adopt internal diameter (or part of internal diameter) to be slightly less than the external diameter of eccentric shaft (8), and make with materials such as having certain elasticity such as spring steel, rubber, plastic cement, can produce the loose-proof sleeve (13) of certain enclasping force to eccentric shaft (8), loose-proof sleeve (13) can not rotate with respect to excessive plate (7), and this also is a kind of anti-loose structure.Can also make certain interference that is combined with of eccentric shaft (8) and rocking arm and base (1) come locking etc.

In order to make reel cage fixing more reliable at a tubular axis (9), a tubular axis (9) can be selected polygon pipe or special pipe.In order to make rocking arm and base (1) more convenient, quicker with the loading and unloading of clamping seats (14) on a tubular axis (9), it can be designed to an end and be the structure of hinge connection structure other end employing clamp nut (15) with anti-turn screw (16) combination.

The invention has the beneficial effects as follows: can the fixing and stressed micromatic setting of reel cage is independent separately, and available polygon pipe is made a tubular axis (9), make the fixing quicker, more reliable of reel cage, make that the pressure amount trimmed is larger, pressure regulation is more convenient, reel cage new destabilizing factor can not occur during pressure regulation.This is just for cotton mill is increased work efficiency, improving the quality of products provides advantage.
