Description

The special-purpose bobbin winoler of a kind of Sewing machines

Technical field

The utility model belongs to the sewing machine technique field, refers in particular to the special-purpose bobbin winoler of a kind of Sewing machines.

Background technology

At present; The bobbin winoler that uses on the general Sewing machines mostly drives the bobbin winoler coiling that is installed on the head with motor shaft through belt or chain wheel driving mechanism, and its weak point is: the one, and motor passes through belt or chain wheel driving mechanism drives bobbin winoler work, and sewing thread is wound on the bobbin winder bracket; Its complex structure; It is big to take up room, inconvenient maintenance, and production cost is high.

Summary of the invention

The purpose of the utility model provides the special-purpose drive motors of a kind of Sewing machines simple in structure, that take up room little, that production cost is low.

The purpose of the utility model is achieved in that

The special-purpose bobbin winoler of a kind of Sewing machines; On a side uprights of installing plate, be hinged with rotating rocking arm; Be provided with the chip cam between column and the rocking arm; the outer end of rocking arm is set with rotating roll; an end of roll is fixed with reel, the other end passes the chute on the installing plate and planker is installed, the end of the Control Shaft that is provided with on the installing plate of column one side is provided with stirs cam and then drives the shifting block of roll away from Control Shaft, and an end of spring is suspended on the cam, the other end is suspended on the roll traction to the hanger bracket near the axial installing plate of control; have the Control Shaft of planker one side to be provided with the control arm that can drive Control Shaft rotation and line ball on the installing plate, a side of installing plate is fixed with the mount pad that can be installed on the Sewing machines housing.

The outside of above-mentioned reel is fixed with the annular ring of elastic wear-resisting.

Be fixed with dismountable bobbin winder bracket on the roll in the above-mentioned planker outside.

On the installing plate of above-mentioned roll one side or the mount pad turnbuckle is installed.

Above-mentioned mount pad is the mount pad of Z type body or U type body or other structure, and a side, the other end that an end of Z type body or U type body is screwed onto installing plate are provided with installing hole.

The utility model is compared the outstanding and beneficial technical effects of prior art:

1, the utility model need be installed on the handwheel in the electrical motor of sewing machine outside annulus wheel is set; Annulus wheel drives the reel rotation and then drives bobbin winoler through the friction power transmission is to wind the line on the bobbin winder bracket, makes that the kind of drive of the utility model is succinct, and it is little to take up room; Easy to maintenance; Fault rate is low, and is easy to operate, and production efficiency is high.

2, the utility model installation application on various types of Sewing machiness that suits.

The specific embodiment

The utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1-4:

The special-purpose bobbin winoler of a kind of Sewing machines; On a side uprights 84 of installing plate 76, be hinged with rotating rocking arm 74; Be provided with chip cam 85 between column 84 and the rocking arm 74; outer end of rocking arm 74 is set with rotating roll 80; end of roll 80 is fixed with reel 71, the other end passes the chute 83 on the installing plate 76 and planker 82 is installed; the end of the Control Shaft 77 that is provided with on the installing plate 76 of column 84 1 sides is provided with stirs cam 85 and then drive the shifting block 75 of roll 80 away from Control Shaft 77; end of spring 86 is suspended on the suppending hole 852 of cam 85 1 sides, the other end is suspended on roll 80 tractions to the hanger bracket 87 near the installing plate 76 of Control Shaft 77 directions, and the opposite side of cam 85 is supported on an end of stage clip 88, and the other end of stage clip 88 is supported on the rocking arm 74; have on the installing plate 76 Control Shaft 77 of planker 82 1 sides to be provided with can to drive that Control Shaft 77 rotates and the control arm 78 of line ball, a side of installing plate is fixed with the mount pad that can be installed on the Sewing machines housing.

Be fixed with the annular ring 73 of elastic wear-resisting on the external cylindrical surface of above-mentioned reel 71.

Be fixed with dismountable bobbin winder bracket 81 on the roll 80 in above-mentioned planker 82 outsides.
