Description
Technical field
The utility model relates to a kind of sewing device, particularly relates to a kind of tucker.
Background technology
In sewing industry, conventionally need to carry out wrinkling pleating, current tucker to cloth and generally include turning cylinder, knife rest is set on turning cylinder, in the end of knife rest, perching knife is set, between knife rest and turning cylinder, torsion spring is set, in use, rely on single torsion spring to exert pressure to perching knife, thereby cloth is exerted pressure, when turning cylinder clockwise rotates, drive perching knife travels forward, make cloth play fold, when perching knife completes after the motion cycle once of front and back, form the fold of a cloth.This tucker carries out when pleating, when perching knife travels forward while shrinking back on earth, turning cylinder swings backward, be with movable knife rack to draw back simultaneously, torsion spring active force on knife rest reduces gradually, when perching knife travels forward again, torsion spring acts on power on perching knife when being minimum in this shuttling movement, now perching knife can not compress cloth, so be not easy cloth to form fold, when machine runs up, just usually occur playing the phenomenon of fold, so occur that cloth forms the unsettled situation of fold; In addition, due to turning cylinder high speed swinging, the whipping of knife rest can be offset the torsion of a part of torsion spring, thereby can make knife rest occur the phenomenon of beating, and has also caused the pleating action of perching knife normally to complete.
So need at present a kind of cloth tucker that can stablize fold badly.
Utility model content
The purpose of this utility model is: in current sewing industry, tucker can not have been stablized the deficiency of fold, provides a kind of and can play to cloth the tucker of fold.
In order to achieve the above object, the utility model adopts following technical scheme to realize:
A kind of tucker, include turning cylinder, on described turning cylinder, be provided with installation shaft, in described installation shaft, be furnished with knife rest, on described knife rest, be provided with perching knife, between described knife rest and described installation shaft, be provided with torsion spring, described knife rest comprises leading portion knife rest and back segment knife rest, described back segment knife rest is arranged in described installation shaft, described torsion spring set is located in described installation shaft, described torsion spring one end is connected with described installation shaft, the other end of described torsion spring is connected with described back segment knife rest, described leading portion knife rest and described back segment knife rest are hinged, on described leading portion knife rest, be provided with extension spring, the other end of described extension spring is connected with described installation shaft.When tucker is worked, perching knife is pressed on cloth, turning cylinder is arranged on actuating unit, thereby turning cylinder drives installation shaft to swing with rotating counterclockwise periodically clockwise, installation shaft promotes back segment knife rest while swinging and moves forward and backward, back segment knife rest drives leading portion knife rest to move forward and backward, thereby realized moving forward and backward of perching knife, when perching knife moves forward, torsion spring makes perching knife compress cloth to the back segment knife rest application of force, perching knife promotes forward cloth and forms a fold, when knife rest moves backward, drive perching knife to move backward, now, torsion spring recovers gradually, the application of force to back segment knife rest is also more and more less, and extension spring is stretched gradually, extension spring is increasing to the application of force of leading portion knife rest, when knife rest moves backward to maximum position, now torsion spring is to the back segment knife rest application of force minimum time, and extension spring lacks to the application of force of leading portion knife rest the maximum state that reached, so perching knife is still pressed on cloth, so when carrying out next shuttling movement, perching knife can be easy to promote cloth and form fold, and the double action due to torsion spring and extension spring, knife rest is tightened up always, avoided knife rest beating in movement.
As preferably, in described installation shaft, be provided with torsion spring regulating block, one end of described torsion spring is connected with described back segment knife rest, and the other end of described torsion spring is connected with described torsion spring regulating block.One end of torsion spring is arranged on torsion spring regulating block, can realizes the adjusting of torsion spring to back segment knife rest application of force size by rotation torsion spring regulating block, further guaranteed that perching knife can compress cloth and form fold.
As preferably, in described installation shaft, be also provided with extension spring regulating block, described extension spring one end is connected with described leading portion knife rest, and the other end of described extension spring is connected with described extension spring regulating block.Can realize the control of extension spring to leading portion knife rest application of force size by rotation extension spring regulating block, further guarantee that perching knife can compress cloth and form fold.
As preferably, described perching knife end is zigzag.When perching knife is moved forward, the promotion cloth being more prone to forms fold.
As preferably, on described back segment knife rest corresponding to described extension spring, be provided with groove.Avoid back segment knife rest to hinder the flexible of extension spring.
As preferably, the end near described leading portion knife rest on described back segment knife rest is provided with groove.Back segment knife rest is contacted with leading portion knife rest near the end downside of leading portion knife rest, and this end upside does not contact with leading portion knife rest, thereby plays the effect to leading portion limiting tool carrier, prevents that leading portion knife rest from rotating too much.
As preferably, on described leading portion knife rest, be provided with limited block with the hinged end of described back segment knife rest.Two limited blocks are set on leading portion knife rest, make reserved less running clearance between leading portion knife rest and back segment knife rest.
As shown from the above technical solution, the beneficial effects of the utility model are:
1, by torsion spring and extension spring, realize perching knife and compress all the time cloth, improved the efficiency that plays fold of tucker to cloth;
2, due to the double action of torsion spring and extension spring, knife rest is tightened up always, has avoided knife rest beating in movement.
