Presser foot operating device of shoemaking sewing machine

摘要

This research is a kind of pain device of roe deer on the shoemaking stick machine for packing sports shoes and upper and insole of leather shoes,The operation of the presser foot during shoemaking sewing is as shown in Figure 5, ㉮ → ㉯ → ㉰ → ㉱,From the twelfth war to the twelfth war, the treasure of the peak was transferred to the edge of the needle for fasting,When arriving at the site, it's the time when the needle goes up and the wire is drawn to fix the beehive tightly. At this time, if the foot doesn't press the beehive property, the needlework will not be smooth,For a long time, when the foot of the water deer descends, it does not firmly grasp the structure of the foot of the water deer on the flag. With the rising of the needle, when the thread is tightened, the property of the Phoenix is pulled to the line, causing the bad influence of frustration, which leads to the problem that the phoenix of the shoe can not finish smoothly, Yes.As a solution to the problem of gas loading, the starting shaft of the up and down moving shaft is installed on the lever which does not support in place, and the furnace of gas loading is inserted into the indicator slot of the working lever on the fuselage. The up and down moving shaft moves up and down to the up and down, and the left and right side of the accompanying letter are attached It can be moved,The supporting plate of the supporting part of the hand iron position is formed by a conical part, forming a sin Ren pavilion with multiple folding parts. The running iron forms a conical inclined part. The conical inclined part of the upper end is inserted into the conical part of the tube. According to the fixed upper and lower angles of the moving shaft, the conical landscape is formedMake the master shrink, make the up and down moving axis firmly fixed in the up and down moving state, prevent the up and down moving axis from moving freely during sewing, so as to make the peak re quotient state very good.
