Further, the arc separated time on piece, near the counterbore two apertures of setting for constraining automatically controlled hot melt
The fire resistant electric wire of tangential knife.
In order to realize that the purpose of this utility model two, technical solution disclosed by the utility model be：
A kind of sewing machine, including preceding any electric heating tangent line movable blade.
Further, further include eedle, needle plate, rotating shuttle, tangent line activity tool apron, the electric heating tangent line movable blade is located at described
It is mounted on the tangent line activity tool apron of sewing machine between needle plate and rotating shuttle, by counterbore thereon or elongated slot.
After receiving trimming action instruction, 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 baseline, at this point, electric heating tangent line movable blade is driven with sewing machine inner cam
It moves and rotates, interior sharp baseline and upper thread by under sewing object point is to its V-shaped mouth, by the upper thread on eedle point in neutral gear.When
Electric heating tangent line movable blade is rotated further, then the upper thread on the eedle in neutral gear is cut far from the automatically controlled hot melt in electric heating tangent line movable blade
Line knife, and the baseline 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 range of tangent line are wider.
Due to current single needle lockstitch m/c, pattern sewing machine, synchronizing trolley, template machine etc., matched using arcuate movement cold cutter
Fixing cutter tangent line is closed, so this automatically controlled hot melt tangential knife can be applied to the above same type, it only need to be by size and installation screw
It changes in hole.
