Abstract

The utility model relates to an electronic yarn storage eccentric oscillation connector in electronic yarn storage device of high-speed shuttleless loom, and is characterized in that: a mounting plate is fixed on mount disk of the yarn storage device; an elastic drum is positioned between the mounting plate and the oscillation seat containing a bearing; the inner surface in top circumference of the elastic drum has a tooth space; a four-head spiral groove is provided in the end face, and a four-head spiral groove is also provided in the lower end face; the four-head spiral groove is engaged with the gear rack of internal and external wefting stand, the gear is engaged with the tooth space, and a eccentric sleeve is set into the hole on oscillation seat containing a bearing; the spacing of wefting on external creel stand can be adjusted precisely through the high-speed rotation of eccentric shaft and the oscillation of eccentric sleeve and oscillation seat, and can be in a row automatically and evenly; through adjusting the elastic drum(6), the diameter distance of internal and external wefting stands can be adjusted accurately in synchronization, with high concentricity and convenient adjusting method, ensuring the preset wefting length is obtained.

Description

Electronic Weft-Storage Eccentrical Swing Connector

(1) technical field

The utility model relates to not have weft spacings adjusting in the shuttle high-speed weaving machine electronic weft storage device, evenly distributed embarking on journey, and regulate the required Electronic Weft-Storage Eccentrical Swing Connector of inside and outside weft yarn frame diameter distance.

(2) technical background

Along with textile machine updates, the supporting amount of electronic weft storage device in the no shuttle high-speed weaving machine is increasing, but regulate for weft spacings in the electronic weft storage device at present and automatic winding displacement is embarked on journey, and aspect such as inside and outside weft yarn frame diameter distance adjustment, owing to structure is unreasonable, the row's of causing yarn spacing is inhomogeneous, beat, inside and outside weft yarn frame diameter distance adjustment trouble, and concentricity is not high, cause phenomenons such as weft yarn fixed length size is inaccurate to take place, influenced the quality and the output of fabric product.China has more than 100 ten thousand electronic weft storage devices to need supporting on the old and new's loom approximately and transforms at present, and we have overcome above-mentioned shortcoming by the Electronic Weft-Storage Eccentrical Swing Connector of exploitation, and electronic weft storage device winding displacement performance is improved.

(3) summary of the invention

The technical assignment of the utility model technical issues that need to address and proposition is to overcome the shortcoming that the existing electronic weft storage device of using exists, and proposes the Electronic Weft-Storage Eccentrical Swing Connector of adjusting of a kind of high accuracy weft spacings and automatic winding displacement and inside and outside weft yarn frame diameter distance adjustment.

The technical solution of the utility model is to comprise that outer weft yarn frame (1), interior weft yarn frame (2), eccentric shaft (3), eccentric bushing (4), tape spool hold swing seat (5), elasticity drum (6), holder (7), it is characterized in that holder (7) is fixed on the fixed disk (8) of electronic weft storage device end face, elasticity drum (6) is installed between holder (7) and the swing seat (5), its elasticity drum (6) upper end circumferential inner surface has teeth groove and end face that the four-start spiral groove is arranged, and there is the four-start spiral groove lower end.The four-start spiral groove is meshed with the tooth bar of inside and outside weft yarn frame (2,1), tape spool in the elasticity drum (6) holds gear and is meshed with upper end internal-round gear groove, eccentric bushing (4) is packed in swing seat (5) hole that tape spool holds, and the tooth bar of inside and outside weft yarn frame (2,1) inserts respectively between elasticity drum (6) and swing (5) or the holder (7).

Its principle is: eccentric shaft (3) is rotation and swing at a high speed, and drives eccentric bushing (4) angle swinging, makes weft yarn obtain accurate spacing on the weft yarn frame (1) outside and aligns equably automatically.Rouse teeth groove, four-start spiral groove and the rack structure of (6) and inside and outside weft yarn frame (1,2) simultaneously by elasticity, manually elasticity drum (6) just can accurately be regulated the diameter distance of inside and outside weft yarn frame (1,2) synchronously equably, the concentricity height guarantees to obtain predefined weft yarn fixed length.The advantage of the utility model Electronic Weft-Storage Eccentrical Swing Connector is rational in infrastructure, function is strong, use the eccentric shaft (3) of back by rotating at a high speed, the swing of eccentric bushing (4) and swing seat (5), can accurately regulate the weft yarn spacing on the creel (1) outside, and align equably automatically, by artificial rotation elasticity drum (6) can be synchronously the accurate inside and outside weft yarn frame (2 of even regulation, 1) diameter distance, the concentricity height, control method is easy, guarantee to obtain predefined weft yarn fixed length, having overcome in the present use electronic weft storage device weft spacings, to regulate the normal row's of generation yarn spacing inhomogeneous, beat and phenomenon such as the not high and trouble of inside and outside weft yarn frame diameter distance adjustment concentricity takes place, the electronic weft storage device performance is improved.

(4) description of drawings

Fig. 1 is the primary structure schematic diagram of the utility model Electronic Weft-Storage Eccentrical Swing Connector.

Among the figure: 1, outer weft yarn frame, 2, interior weft yarn frame, 3, eccentric shaft, 4, eccentric bushing, 5, the swing seat, 6, the elasticity drum, 7, holder.

(5) specific embodiment

Below in conjunction with accompanying drawing the utility model embodiment is described further: its job step is that holder (7) is screwed on the end face fixed disk of electronic weft storage device; The interior rubber ring of elasticity drum (6) is the up-down adjustment sheet fixedly, the fixing lower tooth disk of going up of outer rubber circle; The axle of band gear inserts in the adjusted film perforation of elasticity drum (6), and its gear is meshed with garden teeth groove in elasticity drum (6) upper end; Elasticity drum (6) is screwed with holder (7); The tooth bar of outer weft yarn frame (1) inserts between holder (7) and the elasticity drum (6); Eccentric bushing (4) is packed in swing seat (5) hole that tape spool holds; Swing seat (5) is connected with elasticity drum (6) with screw; The tooth bar of interior weft yarn frame (2) inserts between elasticity drum (6) and the swing seat (5), form an Electronic Weft-Storage Eccentrical Swing Connector, by high speed rotation eccentric axis (3), the swing of eccentric bushing (4) and swing seat (5), can accurately regulate the weft spacings on the outer creel (1), and automatically even winding displacement.By regulate elasticity drum (6) can be synchronously the accurate diameter distance of the inside and outside weft yarn frame (1,2) of even regulation, the concentricity height, method is easy, guarantees to obtain predefined weft yarn fixed length.
