Abstract

The utility model relates to a cord regulator of computer embroidery machine. The existing cord embroidery machines improved from common computerized embroidery machines can not normally be operated at all in actual production. The utility model comprises a conducting wire frame and is characterized in that: the conducting wire frame comprises two side arms which are mutually connected. A via hole used for stringing is formed between the two side arms. A transverse axis penetrated the via hole and the two side arms is arranged on the conducting wire frame. The side arms are provided with adjusting via holes which are used for the transverse axis to move from top to bottom. Adjusting springs are arranged in the adjusting via holes. One ends of the adjusting springs are contacted with the side arms and the other ends of the adjusting springs are contacted with the transverse axis. The transverse axis is sheathed with a bearing which is arranged in the via holes. The utility model can effectively adjust the tightness of cord. The common computer embroidery machine can completely normally proceed cord embroidering and can be provided with multi-functions after being used by matching with the existing fixing cord device.

Description

The rope adjuster of computerized emboridering machine

[technical field]

The utility model relates to the parts on the computerized emboridering machine, specifically a kind of rope adjuster that is used on the computerized emboridering machine.

[background technology]

At present the common computer embroidery machine is merely able to use sub-thread and doublet cord to carry out computerized embroidery, and diameter can not use on the common computer embroidery machine at 1～4 millimeter rope.The embroidery of embroidering out with rope is obviously stronger than the embroidery third dimension of embroidering out with line, and used production cost only needs 1/10th, and production efficiency obviously improves.For this reason, the revolving import rope embroidery machine of a kind of 360 degree occurred, it can be embroidered with rope, but the complex structure of this machine, the manufacturing cost height; Used rope is to be stored in below the head, and the length that stores rope is quite limited, and 2 millimeters rope can only store about 30 meters, complicated operation, and outage rate is higher.For reducing the manufacturing cost of rope embroidery machine, someone has increased by a solid rope device and (has seen Figure of description 1 on the common computer embroidery machine, 2), it comprise connecting plate 1 ', by screw be fixed on connecting plate 1 ' on square support 2 ', square support 2 ' liner one axle sleeve 3 ' and be positioned at axle sleeve 3 ' vertical shaft 4 ', vertical shaft 4 ' an end be with fixed high cover 5 ', the other end be connected with curved presser feet 6 ', square support 2 ' and curved presser feet 6 ' a be provided with spring 7 ', vertical shaft 4 ' be provided with a directed pin 8 ', the gathering sill 9 of square support 2 ' be provided with and directed pin 8 ' be used ', curved presser feet 6 ' on have lacing hole 10 ' and through wires hole 11 ', the embroidery pin that is positioned on the shank is installed with line, when line is embroidered, rope is fixed on the cloth, and formation and line embroider the rope embroidery of the same pattern, and line mainly is that rope is played fixation.But there are a lot of problems in above-mentioned solid rope device, and is uncontrollable as the elasticity of rope, when rope is too tight, bends can occur making when presser feet is turned and takes off, breaks, and also can damage curved presser feet sometimes; When rope was too loose, the meeting clot had influenced production efficiency greatly.In addition, the side-friction that is positioned at pin, shank and needle bar frame on the head is big, and the load of complete machine and curved presser feet is inhomogeneous.In a word, the basic cisco unity malfunction in actual production of the rope embroidery machine after improving on the common computer embroidery machine.

[utility model content]

The technical assignment of technical problem to be solved in the utility model and proposition is the defective that overcomes above-mentioned prior art, the rope adjuster that provides a kind of and existing solid rope device to be used, make common computer embroidery machine after existing improvement embroidery of also normally restricting, dual-use, enhance productivity, reduce production costs.

The technical scheme that the utility model adopted is such: the rope adjuster of computerized emboridering machine, comprise lead frame, it is characterized in that described lead frame comprises two continuous side arms, form the through hole that a wire rope handling is used between two side arms, the lateral shaft that consistent reach through hole and two side arms are arranged on the lead frame, side arm is provided with and is used for the upper and lower mobile adjusting through hole of lateral shaft, regulate through hole and be built-in with regulating spring, one end of regulating spring is against on the side arm, the other end is against on the lateral shaft, is with the bearing that places in the through hole on the lateral shaft.Rope passes the through hole on the lead frame, penetrates in the lacing hole on the existing solid rope device, and rope is conflicted on bearing.Adjuster is as follows to the operation principle that rope carries out the elasticity adjusting: when rope is subjected to pulling force, rope is too tight, and rope can act on bearing, and regulating spring is compressed, bearing drives lateral shaft upper and lower motion in regulating through hole, thereby rope is carried out loosening of appropriateness; When rope was too loose, regulating spring resetted, and rope was carried out the tension of appropriateness.The utility model carries out effectively control and adjusting to the elasticity of rope, be used with existing solid rope device, just can on existing common computer embroidery machine, realize normal rope embroidery, make both energy line embroideries of common computer embroidery machine, the embroidery of also restricting, dual-use greatly reduces the production cost that rope is embroidered, and has improved the production efficiency that rope is embroidered.Because rope is through being connected with lacing hole on the curved presser feet behind the adjuster again, the rope large and small no requirement (NR) of group and can place random.

The rope adjuster of described computerized emboridering machine, lead frame are more than 2 or 2, are set in parallel and pass through a bolt to connect, and one of them lead frame upper end is provided with a fixed head, and fixed head is provided with connecting hole; Lateral shaft on one lead frame is positioned at the top of regulating spring, and the lateral shaft on the adjacent with it lead frame is positioned at the below of regulating spring.Rope is the through hole that passes on all lead frames, penetrates in the lacing hole on the existing solid rope device.When lateral shaft is positioned at the top of regulating spring, corresponding rope also is positioned at the top edge of bearing; When lateral shaft is positioned at the below of regulating spring, corresponding rope also is positioned at the lower limb of bearing.Lateral shaft on the adjacent wires frame shifts to install and the dislocation winding of rope, and the effect when regulating the rope elasticity is more obvious.

The utility model can effectively be regulated the elasticity of rope, after being used with existing solid rope device, makes existing common computer embroidery function embroiderys of fully normally restricting, and has improved the production efficiency that rope is embroidered, and has reduced the production cost of rope embroidery; Common computer embroidery machine dual-use after the improvement, both energy line was embroidered, and the embroidery of restricting again makes common computer embroidery machine multifunction; Rope is even to the load that complete machine reaches existing solid rope device, and the side-friction that pin, shank and needle bar frame are subjected to is little, and rope large and small no requirement (NR) of group and placement are arbitrarily.
