Sewing machines thorn cloth colludes line apparatus
Technical field
The present invention relates to Sewing machines, particularly, the Ci Bu that relates on a kind of Sewing machines colludes line apparatus.
Background technology
Ci Bu on traditional Sewing machines colludes the line apparatus complex structure, the cost height, and transmission is loaded down with trivial details, is unfavorable for maintenance and maintenance, can be very high for maintenance and the maintenance cost used widely, do not meet the production requirement of modern low-cost high-efficiency.
Summary of the invention
At above-mentioned technical deficiency, the purpose of this invention is to provide a kind of simple in structure, cheap, be convenient to maintain and the Sewing machines thorn cloth safeguarded colludes line apparatus.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of Sewing machines thorn cloth colludes line apparatus, comprise by drive source and driving and the rotatable line shaft that is arranged on the body, be arranged on the rotary shuttle shaft that rotates synchronously with described line shaft on the body, be provided with transmission mechanism between described line shaft and the described rotary shuttle shaft, described line shaft is provided with a cam, described cam top is provided with can to slide along the outline of described cam in a bottom and the driven push rod that slides up and down, one end of the upper end of described driven push rod and a connecting rod is hinged, the middle part of described connecting rod is hinged on the body, the other end of described connecting rod is hinged with the shank that a lower end has eedle, described shank vertically is provided with, the below correspondence of described eedle is provided with rotating shuttle, and described rotating shuttle is fixed on an end of described rotary shuttle shaft.
Preferably, described transmission mechanism comprises the belt wheel that is separately positioned on described line shaft and the described rotary shuttle shaft, is arranged on driving belt between two described belt wheels.
Preferably, the outer cover of described driven push rod is provided with and can limits the sleeve pipe that its in the vertical direction slides, and described sleeve pipe is fixedly installed on the body.
Beneficial effect of the present invention is: thorn cloth part and collude the line part and drive work respectively indirectly and directly by a line shaft that is driven by drive source, realize between the two synchronously, and it is simple in structure, transmission is quick, reach cheap, be convenient to maintain and the requirement of the modern production equipment safeguarded, be adapted at promoting the use of in the Sewing machines field.
Description of drawings
Accompanying drawing 1 colludes the structural representation of line apparatus for Sewing machines thorn cloth of the present invention.
In the accompanying drawing: 1, line shaft; 2, rotary shuttle shaft; 3, cam; 4, driven push rod; 5, connecting rod; 6, eedle; 7, shank; 8, rotating shuttle; 9, belt wheel.
The specific embodiment
Below in conjunction with embodiment shown in the drawings the present invention is made following detailed description:
As shown in Figure 1, Sewing machines thorn cloth of the present invention colludes line apparatus and comprises the rotatable line shaft 1 that is arranged on the body by the drive source driving, be arranged on 82 of rotating shuttles that rotates synchronously with line shaft 1 on the body, be provided with transmission mechanism between 82 of line shaft 1 and the rotating shuttles, line shaft 1 is provided with a cam 3, cam 3 tops are provided with a bottom and can slide and the driven push rod 4 that slides up and down along the outline of cam 3, one end of the upper end of driven push rod 4 and a connecting rod 5 is hinged, the middle part of connecting rod 5 is hinged on the body, the other end of connecting rod 5 is hinged with the shank 7 that a lower end has eedle 6, shank 7 vertically is provided with, the below correspondence of eedle 6 is provided with rotating shuttle 8, rotating shuttle 8 is fixed on an end of 82 of rotating shuttles, transmission mechanism comprises the belt wheel 9 that is separately positioned on 82 of line shaft 1 and the rotating shuttles, be arranged on driving belt between two belt wheels 9 (not shown in the accompanying drawing), the outer cover of driven push rod 4 is provided with and can limits the sleeve pipe that its in the vertical direction slides, sleeve pipe is fixedly installed on the body, along with matching with the outline of the cam 3 of rotation and make driven push rod 4 move back and forth up and down in the lower end of driven push rod 4, under the effect of connecting rod 5, drive eedle 6 along with shank 7 moves back and forth up and down, and on the other hand, because the effect of driving belt, rotary shuttle shaft is also rotating, and colludes the line action thereby finish Ci Bu.
Beneficial effect of the present invention is: thorn cloth part and collude the line part and drive work respectively indirectly and directly by a line shaft 1 that is driven by drive source, realize between the two synchronously, and it is simple in structure, transmission is quick, reach cheap, be convenient to maintain and the requirement of the modern production equipment safeguarded, be adapted at promoting the use of in the Sewing machines field.
The foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
