Description
Technical field
Sewing machines automatic thread trimming device of the present utility model relates to a kind of Sewing machines automatic thread trimming device, especially a kind of electric sewer automatic thread trimming device.
Background technology
The trimming mode of electric sewer is in Sewing machines sewing head right edge thread cutter to be installed at present, this thread cutter is a fixed cutting tool that cutting edge is downward, after sewing a diatom, the sewing clothing needed to cut off the end of a thread, so just clothing is walked around the front under the thread cutter cutting edge of right edge again from taking-up under the sewing needle earlier, cut off by cutting edge, so just make the backguy of line tail longer, waste line material, after finishing, the clothing sewing also to manually cut off unnecessary line tail, simultaneously because of the line tail cut gentlier can not automatic naturally water conservancy diversion in container, pollute.
Summary of the invention
The purpose of this utility model provides a kind of energy automatic shearing, reduces the line tail, saves line material and manpower, and can make the automatic water conservancy diversion of cutting of the end of a thread energy in container, the Sewing machines automatic thread trimming device of environmentally-friendly sanitary.
Sewing machines automatic thread trimming device of the present utility model comprises the thread cutter that is installed in Sewing machines sewing head side, the afterbody of this thread cutter also is connected with one and inhales spool, this suction spool other end is connected above the container of a diffusing air valve of band, this also is connected with a vacuum suction pump towards electromagnetic gas valve above container, also have an air valve photoelectric eye that is installed in control electromagnetic gas valve switch under the Sewing machines panel, this air valve photoelectric eye comprises shell and is installed in interior photoswitch circuit and the optoelectronic switch that is installed on the foot-operated connecting rod of Sewing machines.
One of described thread cutter is a pneumatic scissors, and scissors is other a yarn guide channel and trimming hole, and the other end is a tube-shaped tail, and pipeline passes to the scissors place.
The foot-operated connecting rod of Sewing machines that optoelectronic switch is installed divides goes up connecting rod and lower link, exceeding in its junction, displacement is moving to be connected, the a pair of photocell eye of a connecting rod left-right symmetry fixed light electric switch wherein, another connecting rod vertical fixing one catch, the displacement that moves up and down of spacing mobile connection makes just shading light electric eye and leave photocell eye of catch displacement range.
Sewing machines automatic thread trimming device of the present utility model is because its thread cutter is a pneumatic scissors, be installed in Sewing machines sewing head side, when pedal is depressed, the foot-operated connecting rod lower link of pulling moves down, making catch displacement shading light electric eye start electromagnetic gas valve opens, start scissors and inhaled the spool action, foot-operated connecting rod continues to move down pulling and goes up the running of connecting rod startup Sewing machines, after sewing a diatom, the sewing clothing needed to cut off the line tail, so just clothing is just taken out down from sewing needle and directly shift onto the thread cutter, line tail process yarn guide channel and trimming hole are guided under the scissors and are cut off, the place of being cut off only stays very short line tail, or else and then the unnecessary line tail of the artificial pruning of usefulness, and the line tail of cutting is inhaled spool and is drawn onto in the container, and environmental protection is health again; When needs stop to sew, unclamp pedal, move on the foot-operated connecting rod lower link, the out-of-work while of Sewing machines, make the catch displacement leave photocell eye startup electromagnetic gas valve and close air feed, stopped scissors and inhaled the spool action, realized that promptly automatic shearing and sewing work are synchronous, save source of the gas, and reached automatic shearing, and reduce the line tail, save line material and manpower, and make the automatic water conservancy diversion of the end of a thread of cutting in container, the purpose of environmentally-friendly sanitary.
Description of drawings
Fig. 1 is the assembling schematic diagram of the utility model Sewing machines automatic thread trimming device.
Fig. 2 is the local mounting structure schematic diagram of the thread cutter of the utility model Sewing machines automatic thread trimming device.
Fig. 3 is the optoelectronic switch part-structure schematic diagram of the utility model Sewing machines automatic thread trimming device.
The specific embodiment
Below in conjunction with accompanying drawing Sewing machines automatic thread trimming device of the present utility model is described in more detail.
Shown in Fig. 1~3, Sewing machines automatic thread trimming device of the present utility model comprises the thread cutter 1 that is installed in Sewing machines sewing head side, the afterbody of this thread cutter 1 also is connected with one and inhales spool 2, this suction spool other end is connected above the container 3 of a diffusing air valve 4 of band, this also is connected with a vacuum suction pump 6 towards electromagnetic gas valve 5 above container, also have an air valve photoelectric eye 7 that is installed in control electromagnetic gas valve 5 switches under the Sewing machines panel, this air valve photoelectric eye comprises shell 8 and is installed in interior photoswitch circuit 9 and the optoelectronic switch 10 that is installed on the foot-operated connecting rod of Sewing machines.
One of described thread cutter 1 is a pneumatic scissors 11, and scissors is other a yarn guide channel 12 and trimming hole 13, and the other end is a tube-shaped tail 14, and pipeline passes to the scissors place.
The foot-operated connecting rod of Sewing machines that optoelectronic switch 10 is installed divides goes up connecting rod 15 and lower link 16, exceeding in its junction, displacement is moving to be connected, the a pair of photocell eye 17 of a connecting rod left-right symmetry fixed light electric switch 10 wherein, another connecting rod vertical fixing one catch 18, the displacement that moves up and down of spacing mobile connection makes just shading light electric eye and leave photocell eye of catch displacement range.
