Abstract
The utility model relates to a sewing machine component, in particular to a guard device for rolling connecting machine, whose technic proposal is: The utility model comprises a needle bending shaft provided in the casing, one end of the needle bending shaft arranged a lever-type guard board which is shaped like barb with the needle bending shaft. The guard board is provided on the upper part of the guard bed; the lower part of the guard bed is connected with the needle bending shaft through the drive needle; the support is removably connected with the center part of the support bed; the guard bed as the lever and the support as the supporting point form the lever structure. The guard board is opposite to the axial movement of the needle bending shaft. The drive device of the guard board is independent, and is able to adjust independently without the influence of the needle gage adjustment. With the axial movement of the needle bending shaft, the guard board swings periodically in the contrary direction, and as the needle drops, the guard board moves aside so as to avoid directly touching the needle; as the needle bending shaft keeping moving, the guard board touches the needle and corrects the deflective needle for touching the needle when the bending needle hooks the thread so as to guard the needle.
Description
Technical field:
The utility model relates to accessaries of sewing machine, and particularly rolling up and connecting machine protects pin mechanism.
Background technology:
Rolling up and connecting machine is a kind of Sewing machines of special construction, and its cantilever is a tubular, is particularly suitable for two joint closes of cylinder such as sleeve, trousers.Guard mechanism of frizzing machine is to pull the line position that colludes of looper with piercing through the eedle that produces deflection behind the sewing, prevents that bouncing pilotage or broken needle phenomenon from appearring in eedle.There are two kinds of forms in the pin mechanism that protects of rolling up and connecting machine: 1, will protect needle plate on casing, eedle touches with protecting needle plate when piercing through easily mutually, causes eedle wearing and tearing even meeting broken needle.2, will protect needle plate and be installed on the retainer, and can move with retainer though protect needle plate, and protect the needle plate position and must adjust simultaneously with needle gage, and be subjected to the influence of many places fit clearance in the retainer transmission mechanism, it is bigger to protect the pin error at a high speed with low speed the time.Above-mentioned two structures all do not reach and effectively protect the pin effect.
The utility model content:
The purpose of this utility model provide protect the pin effect preferably rolling up and connecting machine protect pin mechanism.
Scheme of the present utility model is: comprise the curved needle shaft that is installed in the casing, curved needle shaft one end is provided with lever and protects needle plate, protects needle plate and curved needle shaft is barb shape.Protect needle plate and be fixed on and protect needle stand top, protect the needle stand bottom and be connected with curved needle shaft by trundle, support and carrier base middle part flexibly connect, and are that lever, support are that fulcrum forms lever construction to protect needle stand.It is opposite with the axial activity direction of curved needle shaft to protect needle plate.
Curved needle shaft and trundle junction are shaped on longitudinal fluting, and the trundle periphery is shaped on the plane with curved needle shaft groove matched in clearance.Support is connected by screw and carrier base, passes to protect the needle stand end jump ring is installed.Protect needle plate and be shaped on long slot bore, fix by screw and carrier base, head is shaped on chamfering.
The utility model has the advantages that: the transmission mechanism that protects needle plate is independent, can adjust the influence that not regulated by needle gage separately.The curved needle shaft axially-movable makes and protects needle plate and do periodic in the other direction swing, protects needle plate and abdicate the space when eedle falls, and avoids directly touching with eedle; When curved needle shaft continues motion, protect needle plate contact eedle and correct the eedle of deflection, touch eedle when making looper collude line, play the pin effect of protecting.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model assembling schematic diagram.
Fig. 3 protects the pin schematic diagram for the utility model.
The specific embodiment:
See figures.1.and.2, below describe by left and right directions shown in Figure 1.Curved needle shaft 1 is installed in the casing, and curved needle shaft 1 is equipped with looper 9.Curved needle shaft 1 passes on left trundle 2 and protects needle stand 3 flexible connections.Support 4 is movably connected in the middle part of protecting needle stand 3, and support 4 other ends and carrier base 6 are fixing, and carrier base 6 is fixed on the casing.Protect needle plate 5 and be fixed on and protect needle stand 3 tops, protect needle plate 5 and be barb shape with curved needle shaft 1, forming to protect needle stand 3 is that lever, support 4 are the lever construction of fulcrum.
With reference to Fig. 3, curved needle shaft 1 vertically is shaped on groove in that the left side, looper 9 place is installed, and the plane is all made in trundle 2 left sides, right side, bottom, and with curved needle shaft 1 groove matched in clearance, trundle 2 runs through and protects needle stand 3 lower through-hole.Because the matched in clearance of curved needle shaft 1 groove and trundle 2, when curved needle shaft 1 radially rotated, trundle 2 kept motionless, when curved needle shaft 1 moves axially, drove trundle 2 and moved.Support 4 passes that to protect needle stand 3 intermediate throughholes ends fixing with jump ring 7, prevents from support 4 and protect needle stand 3 to break away from.Carrier base 6 right sides are shaped on groove, and support 4 other ends just snap in carrier base 6 grooves, and it is fixing with support 4 that screw 8 passes carrier base 6.Protect needle plate 5 afterbodys and be shaped on long slot bore, will protect needle plate 5 by screw and be fixed on and protect needle stand 3 tops, screw is in the long slot bore adjustable positions, about adjust and protect needle plate 5, make and protect needle plate 5 and be in the best and protect the pin position.
With reference to Fig. 4, when curved needle shaft 1 was in the right side, eedle 10 was positioned on the needle plate, and the needle plate 5 that protects on carrier base 6 tops is positioned at the left side.When curved needle shaft 1 swings and left axially during combined running, by trundle 2 and curved needle shaft 1 groove fit, protecting needle stand 3 bottoms moves to left, under support 4 supports, protect needle stand 3 tops and slowly move to right, eedle 10 pierces through sewing and moves downward, and runs to when protecting needle plate 5 top levels, protect the left side that needle plate 5 also is in eedle 10, avoid directly touching with eedle 10.Curved needle shaft 1 continues to move to left, eedle 10 moves down, because sewing is moved to the left under the effect of charging tooth, driving eedle 10 is tilted to the left, protecting needle plate 5 moves right under the drive of curved needle shaft 1, and run into eedle 10 bar positions, along with curved needle shaft 1 and eedle 10 further move, protect needle plate 5 move to right correct the right side eedle 10 to the upright position.When curved needle shaft 1 moved to Far Left, it was slack to protect needle plate 5, and eedle 10 is conflicted at ad-hoc location, made things convenient for looper 9 to collude line, avoided eedle 10 to be interrupted by looper 9.Protect needle plate 5 and be shaped on chamfering, can better correct eedle 10 positions with the head that eedle 10 contacts.
