Description
Technical field
It lives the present invention relates to sewing machine field more particularly to a kind of electric heating tangent line movable blade and comprising this electric heating tangent line
The sewing machine of moving knife.
Technical background
The present sewing machine with rotating shuttle, majority coordinate fixing cutter tangent line using camber movable blade, such as：Single needle flush joint
Machine, pattern sewing machine, synchronizing trolley, template machine etc..This knife is all cold shears knife, i.e., by an arcuate movement knife and a fixing cutter group
Into.Its two mutual friction and Extrusion, cutting edge touch cutting edge, so as to fulfill the function of cutting line.So as to cause its serious wear.In order to protect
It is demonstrate,proved using wearability it is necessary to using the heat treatment process of expensive material and complexity.
Moreover, current this cold cut camber movable blade and fixing cutter, the ability of tangent line is limited, for thick line and
Difficulty cuts the line of material, there is the situation that can't cut line, and cut it is very laborious during this line, so as to more shorten service life of cutter.
The content of the invention
An object of the present invention is to provide a kind of electric heating tangent line movable blade, and another object of the present invention is provided comprising this
The sewing machine of electric heating tangent line movable blade, uses hot melt tangential knife, sewing thread is fused, so as to can effortlessly break and nothing
Abrasion or even line thick again can also easily be cut off.
In order to achieve the object of the present invention one, technical solution disclosed by the invention is：
A kind of electric heating tangent line movable blade, it is characterised in that：Including the arc separated time piece made of metal folding（It can be circular arc
Shape or fold-line-shaped）, automatically controlled hot melt tangential knife, the arc separated time piece is including interior point, outer point and in the interior point
Side neutral gear, the interior point can be by the upper threads of eedle side point in the neutral gear, and the V-type mouth among the interior point and outer point is used for
It sticks in and promotes the bottom line and upper thread under sewing object；The automatically controlled hot melt tangential knife is by high temperature resistant tangent line piece and fire resistant electric wire
Composition, after being powered to the fire resistant electric wire, the high temperature resistant tangent line piece can generate heat to more than sewing thread fusing point；The electricity
Control hot melt tangential knife is installed in the arc separated time on piece, and the tangent line end of the high temperature resistant tangent line piece is towards the V-type mouth.
Further, the tangent line end of the high temperature resistant tangent line piece of the automatically controlled hot melt tangential knife is upturned and the tangent line at this
Direction formation angle a, 150 ° >=a >=0 °.
Further, the automatically controlled hot melt tangential knife is installed in the high-temperature insulation seat by high-temperature insulation gluing
On.
Further, further include high-temperature insulation seat, the high-temperature insulation seat directly with the arc separated time piece simultaneously
Making be integrated or it is independent make after the arc separated time on piece is installed in by trip bolt, on the high-temperature insulation seat
Installation notch are opened up, the automatically controlled hot melt tangential knife is embedded in the installation notch.
Further, the arc separated time on piece, corresponding to kerve is set at the V-type mouth, the kerve can hold
It receives the bottom line and upper thread separated, and the start position of the bottom line separated and upper thread can be reduced, with the interior point point in neutral gear
Upper thread on eedle is about in 90 degree so that bottom line and upper thread in the V-type mouth slide to the high temperature resistant tangent line piece.
Further, the arc separated time on piece, two apertures are set for constraining automatically controlled hot melt near the counterbore
The fire resistant electric wire of tangential knife.
In order to achieve the object of the present invention two, technical solution disclosed by the invention is：
A kind of sewing machine includes preceding any electric heating tangent line movable blade.
Further, eedle, needle plate, rotating shuttle, tangent line activity tool apron are further included, the electric heating tangent line movable blade is located at described
It is mounted between needle plate and rotating shuttle, by counterbore thereon or elongated slot on the tangent line activity tool apron of sewing machine.
After trimming action command is received, eedle downlink, when eedle uplink returns, the upper thread on eedle is by rotating shuttle
It catches on, and the upper thread under the sewing object caught on is close to bottom line, at this point, electric heating tangent line movable blade is driven with sewing machine inner cam
It moves and rotates, the upper thread on eedle to its V-shaped mouth, is divided the bottom line under sewing object and upper thread point in neutral gear by interior point.When
Electric heating tangent line movable blade is rotated further, then the upper thread on the eedle in neutral gear is cut away from the automatically controlled hot melt in electric heating tangent line movable blade
Line knife, and the bottom line and upper thread under the sewing object to be cut off then are met to automatically controlled hot melt tangential knife and are cut off.
By said program as it can be seen that using this automatically controlled sewing machine for heating tangential knife, existing arc can be replaced to live completely
Dynamic cold cutter and the fixing cutter with its adapted, the longer life expectancy of knife, the scope of tangent line are wider.
Due to current single needle lockstitch m/c, pattern sewing machine, synchronizing trolley, template machine etc., matched somebody with somebody using arcuate movement cold cutter
Close fixing cutter tangent line, thus this automatically controlled hot melt tangential knife can be applied to more than similary type, only need to be by size and installation screw
It changes in hole.
