Abstract
The invention discloses a cloth-needling thread-hooking device of a sewing machine. The cloth-needling thread-hooking device comprises a power shaft and a rotating shuttle shaft, wherein the power shaft is arranged at a machine body in a rotatable manner under the drive of a driving source; the rotating shuttle shaft is arranged on the machine body and synchronously rotates with the power shaft; a transmission mechanism is arranged between the power shaft and the rotating shuttle shaft; the power shaft is provided with a cam; a driven post rod is arranged above the cam and the lower end part of the driven post rod can slide up and down along the sliding of the external contour of the cam; the upper end of the driven post rod is hinged with one end of a connecting rod; the middle part of the connecting rod is hinged on the machine body; the other end of the connecting rod is hinged with a needle rod of which the lower end is provided with needles; the needle rod is vertically arranged; rotating shuttles correspondingly arranged below the needles; and the rotating shuttles are fixed at one end of the rotating shuttle shaft. According to the invention, a cloth-needling part and a thread-hooking part are respectively driven indirectly and directly by the power shaft driven by the driving source to work so as to realize synchronizing of cloth-needling and thread-hooking; moreover, the cloth-needling thread-hooking device disclosed by the invention has the advantages of simple structure and high transmission speed, meets the requirements of low cost and convenience for serving and maintaining and is suitable for popularizing and applying in the field of sewing machines.
Description
Technical field
The present invention relates to Sewing machines, particularly, the thorn cloth that relates on a kind of Sewing machines is colluded line apparatus.
Background technology
Thorn cloth on traditional Sewing machines is colluded the line apparatus complex structure, and cost is high, 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
For above-mentioned technical deficiency, the purpose of this invention is to provide a kind of simple in structure, cheap, be convenient to the cloth-needling thread-hooking device of sewing machine that maintains and safeguard.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of cloth-needling thread-hooking device of sewing machine, comprise by drive source and drive and rotatably be arranged on line shaft 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, be provided with a cam on the described line shaft, 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 arranges, 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 indirectly and directly drive respectively work by a line shaft that is driven by drive source, realize between the two synchronously, and 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 is the structural representation of cloth-needling thread-hooking device of sewing machine 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, cloth-needling thread-hooking device of sewing machine of the present invention comprises by drive source and drives and rotatably be arranged on line shaft 1 on the body, be arranged on rotating shuttle 8 axles 2 that rotate synchronously with line shaft 1 on the body, be provided with transmission mechanism between line shaft 1 and rotating shuttle 8 axles 2, be provided with a cam 3 on the line shaft 1, 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 arranges, the below correspondence of eedle 6 is provided with rotating shuttle 8, rotating shuttle 8 is fixed on an end of rotating shuttle 8 axles 2, transmission mechanism comprises the belt wheel 9 that is separately positioned on line shaft 1 and rotating shuttle 8 axles 2, 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 the lower end of driven push rod 4 match with the outline of the cam 3 of rotation and so that driven push rod 4 move back and forth up and down, 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 thorn cloth.
Beneficial effect of the present invention is: thorn cloth part and collude the line part and indirectly and directly drive respectively work by a line shaft 1 that is driven by drive source, realize between the two synchronously, and 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.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the personage who is familiar with technique can understand content of the present invention and according to this enforcement, 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.
