Abstract

The utility model relates to the improvement of a tool sewing clothes, which is the improvement of a thread feeding mechanism of a clothes vehicle bottom thread. The improved thread feeding mechanism of the bottom thread is composed of a shuttle bed and a compound shuttle frame. A lower axle is hollowed along a middle axle line. The thread feeding operation of the bottom thread is conducted by a thread frame of the machine through a thread positioning buckle, the center hole of the lower axle and the center hole of the shuttle bed to the compound shuttle frame. A shuttle core sleeve, a shuttle core and a bottom thread winding device are saved and only the shuttle bed and the shuttle frame are a little changed. Thus the structure is simple, the manufacture is easy and the cost is low. The bottom thread does not need to be specially wound and the bottom thread does not need to be changed by stopping the machine in the production processes and the labor productivity is increased.

Description

No shuttle locking-type flat seam machine

The utility model relates to a kind of improvement of sewing clothes instrument, and promptly the sewing machine bottom line is for the improvement of line mechanism.

The instrument of sewing clothes such as popular in the market high speed, medium speed flat bed sewing machine, double needle machine, embroidery machine, floricome machine, lockstitch button holder is made up of head, platen, frame.Bottom line as the head vitals supplies line mechanism, is to be made of shuttle sleeve, shuttle race, shuttle, four major parts of shuttle frame.Shuttle race rotates, and the shuttle frame is fixed.Be contained in the bobbin case around the shuttle of reaching the standard grade, bobbin case is set in the shuttle frame again.This class flat seam machine is owing to adopt shuttle that bottom line is provided, the shuttle frame that matches with it, shuttle sleeve complex structure, involve great expense, be far longer than the shuttle wire containing with the line amount in the industrial production, so need to change again and again the bottom line shuttle, both caused defectives such as over-lapping stitch on the sewing quality is many, labor productivity is reduced greatly.

The bottom line that the purpose of this utility model provides a kind of flat seam machine is for line mechanism, makes simple in structurely, and cost reduces, and production process can provide bottom line continuously, needn't shut down the shuttle changing heart, increases work efficiency.

In order to achieve the above object, head bottom line of the present utility model is configured to by shuttle race and compound shuttle for line mechanism, profile when compound shuttle frame profile such as original shuttle frame and shuttle sleeve are combined, shuttle race is bored a hole from the axis, and be fixed on an end of lower shaft, compound shuttle frame is bored a hole from the axis, is fixed in the shuttle race; The lower shaft that drives the shuttle race rotation is along axis hollow; Bottom line for line by the coil holder on the machine through alignment buckle, the centre bore of the centre bore of lower shaft, shuttle race is to compound shuttle frame.For suitable with old machine, the shuttle frame of the profile of compound shuttle frame and existing flat seam machine, the appearance similar when shuttle is combined into one, its outer wall is cylindric, wall has the landolsring of using as guide rail outward, one bottom surface is more smooth, the little arch in another bottom surface, and there is a centre bore at the place, axis; The arch bottom periphery has the semicircle shirt rim, shirt rim one end has a nick breach, equally is used for fixing compound shuttle frame with original shuttle frame, on the adjacent wall of nick breach a pin mouth is arranged, by near the bottom surface little breach dark inwards among a small circle recessed hole is arranged also, the pin of buying car in installments of communicating with the pin mouth is up and down.

When wearing bottom line, after bottom line is pulled to the alignment button from coil holder, play to wear to shuttle race and compound shuttle frame centre bore getting final product with a little pierce tap line from an end centre bore of lower shaft always.For the various sewing machine machines that adopt gear to be connected between shuttle race and the lower shaft, bottom line can be through the centre bore of lower shaft, but directly passes through to shuttle race and compound shuttle frame centre bore by the gear minor axis centre bore that is connected with shuttle race behind the alignment button.

Through change to shuttle race rib frame, saved shuttle, shuttle sleeve and Winder, structure is simplified greatly, is convenient to make, and cost is lower, and mill changes littler, can further improve rotating speed, is convenient to C﹠M.

Running saves the time of coiling shuttle bottom line, also needn't be for changing bottom line shuttle shutdown etc., the labor productivity of Ti Gaoing greatly.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 supplies the line mechanism structure chart for the flat seam machine bottom line.

Fig. 2 is compound shuttle shelf structure figure.

Fig. 3 is compound shuttle frame side view.

Among Fig. 1,1 is compound shuttle frame, and 2 is shuttle race, 3 is lower shaft, and shuttle race is along axis hollow, and shuttle race is fixed on an end of lower shaft, compound shuttle frame is fixed in the shuttle race, and 4 is bearing, and 5 is vertical pivot, 6 is oil pump, and 7 is the meshing gear of vertical pivot and lower shaft, and lower shaft 3 can prolong herein, in order to avoid stain bottom line when wearing bottom line, 8 is the alignment button, is fixed near the aperture, axle center of lower shaft, 9 is platen, and 10 is the car pin.

Among Fig. 2, Fig. 3, the profile of compound shuttle frame and original shuttle sleeve and shuttle frame are combined into one the back appearance similar, be cylindric, inside can be solid or hollow, wall has the landolsring of using as guide rail 11 outward, one bottom surface is more smooth, another bottom surface 12 little arches, there is a centre bore 13 at axis place, and the arch bottom periphery has a half-circle skirt limit 14, and a nick breach 15 that is used for fixing compound shuttle frame is arranged on the shirt rim, with the adjacent pin mouth 16 that has on the wall of nick breach, near near the bottom surface the nick breach a dark inwards recessed hole 17 is arranged, communicate with pin mouth 16, the pin of buying car in installments is up and down.
