Abstract
The utility model discloses a sewing thread tension regulating device of multi needle sewing machine, which comprises a fixing frame which is fixed on the housing of the sewing machine and a plurality of sewing thread tension regulating units which are arranged on the fixing frame. Each sewing thread tension regulating unit comprises a frame which is fixed on the fixing frame. A plurality of sewing thread tension regulating knobs are arranged on each frame to elastically clamp a sewing thread. In addition, each frame is in sliding way provided with a thread tension releasing slide which is provided with a plurality of wedge parts respectively corresponding between the first chuck plate and the second chuck plate of the sewing thread tension regulating knob. An interlocking bar pivots with each thread tension releasing slide in order to link each wedge part of each thread tension releasing slide to move towards each corresponding sewing thread tension regulating knob. After the wedge parts are inserted between the corresponding first chuck plate and the second chuck plate of the sewing thread tension regulating knob, the distance of the first chuck plate and the second chuck plate is expanded to release the sewing thread which is clamped by each sewing thread tension regulating knob.
Description
Technical field
The utility model relates to a kind of thread tension regulator of multineedle sewing machine, refer in particular to an a kind of side that is installed on Sewing machines, and by a gangbar a plurality of thread tension releasing slides that link simultaneously, so that a plurality of thread tensions are adjusted the thread tension regulator that buttons carry out thread tension adjustment operation.
Background technology
Generally being applied at present the multineedle sewing machine of industrial sewing, as shown in figure 12, is to be placed in the long-range coil holder 51 of Sewing machines 52 by one, is socketed with the suture of a plurality of rolling, each volume suture is directed in the suture needle of Sewing machines 52 again.For each suture when the sewing; can be more smooth-going, usually can near the long-range coil holder 51 of Sewing machines 52, many group thread tension adjusters 53 be set, each group thread tension adjuster 53; press folder one suture respectively accordingly, pass in the suture tension of each suture needle or the degree that relaxes with adjustment.
In the time will unclasping suture, by the floor push (not shown) affect the Sewing machines casing behind connecting rod (not shown) pulling cable wire 54 and whole thread tension adjusters 53 drawn back unclasp suture.Because above-mentioned thread tension adjuster 53, be to be installed near the long-range coil holder 51 of Sewing machines 52, therefore following shortcoming is just arranged on using:
1. because thread tension adjuster 53 is arranged at the distant place of Sewing machines 52, so in the sewing operation carries out, when the operator finds, wherein have the tightness of some suture too lax or too tightly need give when adjusting, hand must be extended at a distance and adjust, therefore very inconvenience.
Since thread tension adjuster 53 far apart from Sewing machines 52, can't strain at really and Sewing machines 52 between suture, the tension force of suture can't be adjusted exactly, and suture very easily is torn, cause the inconvenience on the sewing operation.
In view of this utility model designer is studied innovation, discloses a kind of thread tension regulator of multineedle sewing machine.
Summary of the invention
The purpose of this utility model is to provide a kind of thread tension regulator of multineedle sewing machine, and it comprises: a fixed mount is installed on the casing of Sewing machines; A plurality of thread tension adjustment groups, be installed on the described fixed mount, each described thread tension adjustment group contains a framework, be fixed on the described fixed mount, on each framework, be equiped with a plurality of thread tensions and adjust buttons, to distinguish flexibly clamping one suture, in addition on each framework, sliding establish a thread tension releasing slide, make this thread tension releasing slide be provided with a plurality of wedge portion, a respectively corresponding thread tension is adjusted between first and second chuck of button; An and gangbar, pivot connects each thread tension releasing slide respectively, each wedge portion with each thread tension releasing slide that operationally links adjusts the button displacement towards each corresponding thread tension, and after inserting each corresponding thread tension and adjusting between first and second chuck of button, support the spacing between this first and second chuck, discharge the suture that each thread tension is adjusted the button clamping.Reached following purpose of design so:
1. be installed in a side of Sewing machines, the operator can directly carry out loose ends or each corresponding suture is carried out the adjustment operation of tight degree on the seat, make operation more easy, quick, and also the utmost point meets worker's job requirements.
2. can adjust button to a plurality of thread tensions simultaneously and carry out the loose ends operation, make the loose ends operation more quick and precisely.
Preferred embodiment of the present utility model can be by following for being able to distinct in the specific embodiment and the description taken in conjunction with the accompanying drawings.
