Abstract
The utility model relates to a thread severing and backward running preventing device for a sewing machine, composed of a guiding element, a pressing rod, a push rod, two reset springs, an upper and a lower blades, etc., wherein, the guiding element is provided with two ladder grooves and one guide groove; one ladder groove is provided with a thread pressing rod and one reset spring, and the other ladder groove is provided with one reset spring, then sheathed on an original pressing rod of a sewing machine and then fixed on the lower end of the pressing rod via the guide groove; the upper and the lower blades are respectively fixed on the guiding element and an upper plate of a push tooth of the sewing machine. The utility model can reduce frequent thread severing time when the sewing machine works, and meantime can ensure the threads of the sewing machine can not release from needle eyes.
Description
The utility model is the invention about Sewing machines trimming and anti-down line apparatus.
Sewing machines is the essential instrument of clothes processing, no matter but be industrial or domestic sewing machine, when work, the family manufacture clothes often need to use continually scissor cut Sewing machines the end of a thread, if still can be ignored, but if industrial production in enormous quantities, then must consider this problem, in the process of making, run into the Sewing needles line that frequently comes off and then further taken available process time, thereby make Sewing machines production efficiency influenced again.
The purpose of this utility model provides a kind of Sewing machines trimming and anti-down line apparatus, and it can shear sewing machine thread apace, and can prevent the off-line of Sewing needles.
Structure of the present utility model sees shown in the accompanying drawing that this device is made up of with the bottom knife that is fixed on Sewing machines propelling tooth upper plate tangent line that is fixed on former Sewing machines compressing rod lower end and anti-down line component; Wherein tangent line, anti-down line component comprise guide, line ball bar, top blade, depression bar, push rod and two back-moving springs and a top spring screw; Top blade is fixed on the guide side, being shaped on two step troughs and a gathering sill, a step trough on the guide packs into and is enclosed within behind the back-moving spring on the line ball bar and with top spring screw shutoff, another step trough is put into and is enclosed within the screw of compressing rod lower end on gathering sill and former Sewing machines compressing rod bottom swage set piece behind the back-moving spring and fixes, and the two fixedlys connected depression bar and push rod by the guide upper hole; Former Sewing machines advances the tooth upper plate to have through hole.
The above-mentioned line ball bar of the utility model can be formed by connecting through screw by line ball upper boom and line ball lower beam, and line ball lower beam one end is embedded with the line ball head that a flexible material is made.
The utility model is simple in structure, and it is convenient to install, and no matter is that industry is not that domestic sewing machine all can be installed, and result of use is good, can improve the service efficiency and the production efficiency of Sewing machines greatly.
Accompanying drawing has been described embodiment of the present utility model:
Fig. 1 is that the utility model is installed in the structural representation on the Sewing machines compressing rod lower end,
Fig. 2 is the left view of Fig. 1,
Fig. 3 is the main cutaway view of guide 1 among Fig. 1,2,
Fig. 4 is that cutaway view is looked in the left part of Fig. 3,
Fig. 5 is the structural representation of the propelling tooth upper plate 13 on the former Sewing machines after the improvement,
Fig. 6,7 respectively among Fig. 1 the master of top blade 2 look and left view.
Fig. 8,9 is respectively that the master of bottom knife 6 among Fig. 1 looks and left view.
Figure 10,11 is respectively that the master of line ball upper boom 3 among Fig. 1 looks and left view.
Figure 12,13 is respectively that the master of line ball lower beam 4 among Fig. 1 looks and left view.
Figure 14,15 is respectively that the master of line ball head 5 among Fig. 1 looks and left view.
In the utility model accompanying drawing 1,2, guide 1, binder upper boom 3, binder lower beam 4 available metals or plastics are made, and upper and lower blade 6 and 2, back-moving spring 8 and 11 etc. are made with metal.Be shaped on two step troughs and a gathering sill in the guide 1, one of them step trough is put on the former Sewing machines compressing rod 12 of a back-moving spring 11 back covers, and gathering sill being stuck in compressing rod 12 lower ends with the lower end hold-down screw of former Sewing machines compressing rod 12, another step trough is put into a back-moving spring 8 backs with top spring screw 10 shutoff; Top blade 2 is fixed on the line ball bar side on one side of guide 1, the line ball bar can be made into the line ball bar, down two sections on line ball bar is formed by connecting through screw, following line ball bar 4 one ends can be packed with a line ball head 5 made from flexible material shown in Figure 15,16, arcuation is made at two edges of top blade 2 blades, and the centre is the blade of tangent line; Bottom knife 6 is screwed as shown in Figure 1 below former Sewing machines advances tooth upper plate 13, and former Sewing machines advances tooth upper plate 13 to need to increase a through hole, so that bottom knife 6 cutting edges stretch out.
Using method of the present utility model is such: when cloth is sewn into the end, only need and to push away on the depression bar 7, drive push rod 14 is depressed guide 1 and is made the line ball bar push down sewing machine thread earlier, it can not be deviate from pinprick, again along with guide 1 continues descending, top blade 2 on the guide 1 will cooperate with the bottom knife 6 on being fixed on propelling tooth upper plate 13 cuts off sewing machine thread, if at this moment loose one's grip, guide 1 is enclosed within former Sewing machines compressing rod 12 upper reset springs 11 and upsprings in its inner step groove.Can prevent that on the basis of trimming fast sewing machine thread from deviating from from pinprick so just guarantee to have reached, also just improve the production efficiency of Sewing machines.
