The spindle line release braking device can be compatible to thick yarns and thin yarns, free of yarn breaking and even in knitting.
Description
Technical field
The utility model relates to a kind of spindle brake structure of braiding machine, especially a kind of high-speed knitter spindle pay-off brake device.
Background technology
The high-speed braider spindle pay-off brake device that uses on the present braiding machine has ejector pin make progress brake type and ratchet press-down type.
In Fig. 1, the make progress structure of brake type of described ejector pin is: ejector pin makes progress has a floral disc (1-2) on the ingot body (1-1) of brake type, floral disc (1-2) is enclosed within on the yarn tube axis (1-3), and yarn tube axis (1-3) is connected with ingot body (1-1), and ingot body (1-1) is provided with ejector pin (1-4).Ejector pin (1-4) upper end withstands under the floral disc (1-2) in the groove, the wired pendant of ingot body (1-1) overcoat (1-5), line pendant (1-5) is connected with transverse axis (1-6) in the ejector pin (1-4), yarn during work on the spool falls the rear end with line and mentions, line pendant front end down bears down on one and cuts transverse axis, force ejector pin to break away from groove under the floral disc, under the effect of yarn pulling force, spool begins unwrapping wire, thereby line pendant rear end decline front end rises, and ejector pin upwards rises under the stage clip effect, heads under the floral disc in the groove, check floral disc, unwrapping wire stops.
In Fig. 2, described ratchet press-down type brake structure is: be connected with yarn tube axis (2-2) on the spindle support (2-1), yarn tube axis (2-2) overcoat has spool (2-7), be wound with yarn in the spool (2-7), the lower end cover has floral disc (2-3), spindle support (2-1) end is connected with guide pillar (2-4), and guide pillar (2-4) below connects wired pendant (2-5) and ratchet (2-6), and ratchet (2-6) is pressed in floral disc (2-3) alveolus.Yarn during work on the spool is mentioned the line pendant, to the appropriate location ratchet is boosted, ratchet is forced to break away from floral disc, floral disc relays line at the effect backspin of power, namely and line pendant begins to glide, ratchet falls under the effect of spring pressure, thereby ratchet is inserted in checks floral disc in the floral disc alveolus, the spool rotation stops, and unwrapping wire stops.
The spindle brake device shortcoming of above two kinds of forms: braking gap is large, stops unstable, and brake transmission resistance is large, causes unwrapping wire insensitive, easily broken yarn, and the transmission parts are fragile, thereby affect quality and the output of braiding machine.
The utility model content
The purpose of this utility model is that a kind of high-speed knitter spindle pay-off brake device will be provided, and solves existing spindle brake device braking gap large, stops unstable the large problem of brake transmission resistance.
The purpose of this utility model is achieved in that this brake gear comprises: spool seat, brake hook and connecting rod; Brake hook one side pressure under the spool seat on the circular groove sidewall, the other end of the hook that brakes is connected with connecting rod.
Described spool seat is discoid, and is porose in the centre of disk, be evenly equipped with cylinder above the circumference in the same center of circle of centre bore, circular inner groove is arranged below disk, the circular inner groove inwall is arranged with the platform of projection.
Described brake hook is " L " shape, and front end is ratchet shape, is connected to below the spool seat in the circular inner groove, and the bending part of brake hook is provided with aperture, and aperture is socketed on the fulcrum shaft, and the rear end is connected with rod slide.
Described connecting rod is " J " shape, and the bottom of connecting rod is connected with the brake hook, and the upper end is porose.
Beneficial effect, owing to having adopted such scheme, when spindle takes up one's knitting, yarn (5) is mentioned line pendant (6), when line pendant (6) is run into connecting rod (2) upper end, connecting rod (2) beginning upward sliding, the pull-up that brake hook (3) rear end is made progress by connecting rod (2), enclosing fulcrum shaft (7) rotates, brake hook (3) rear end platform rises, and the front end ratchet is rotated down, the circular inner groove sidewall that brake hook (3) is forced to break away from spool seat (1) lower end, spool seat (1) begins to rotate unwrapping wire under spool (4) and yarn (5) pulling force effect.Line pendant this moment (6) begins to glide under the stage clip effect, and connecting rod (2) begins lower movement under the effect of stage clip (8), so brake hook (3) encloses fulcrum shaft (7) reverse rotation, brake hook (3) rear end falls, and front end rises; Brake hook (3) front end ratchet simultaneously again by on the circular inner groove sidewall that is pressed in spool seat (1) lower end, so spool seat (1) is checked, spool (4) stops unwrapping wire.
Solved existing spindle brake device braking gap large, stopped unstable, the large problem of brake transmission resistance reaches the purpose of this utility model.
Advantage: this pay-off brake device has adopted lever principle, the sidewall control parking line of the circular inner groove of some touch controls spool seat lower end makes the spindle unwrapping wire light and sensitive, weares and teares little, the accurate gapless of braking, the transmission component structural is simple, cost is low, flexibility ratio is high, long service life.The rove spun yarn is compatible, and broken yarn does not weave evenly, has improved weaving quality, and output.
