Description

The cutting mechanism of high speed clothes left front bead cutter

One, affiliated technical field

The utility model belongs to technical field of sewing equipment, relates to a kind of left front bead cutter, refers in particular to the cutting mechanism in a kind of left front bead cutter.

Two, background technology

Along with the continuous development of science and technology and the continual renovation of sewing device, in the past by hand with the operation of scissors, can replace the making clothes with machinery now.As cut the sheet up and down of left front in the past by hand with scissors, can use clothes left front bead cutter to finish now.Cutting mechanism is the key mechanism of clothes left front bead cutter, and it is made of knife bar, needle plate, push pedal, pressing plate, presser feet, knife rest and cutting knife etc.But the cutting mechanism design of at present commercially available clothes left front bead cutter is unreasonable, and cutting knife can not move, knife rest can not slide, along with its gap of wearing and tearing of blade is increasing, yet owing to not adjusting in the gap, can only replace cutting knife, and the sheet up and down of left front and collar can not cut simultaneously.

Three, utility model content

The purpose of this utility model is to provide a kind of cutting mechanism of high speed clothes left front bead cutter, and it can cut the sheet up and down of left front and collar simultaneously, can adjust the gap of blade automatically, improves cutting ability, prolongs the service life of blade.

For achieving the above object, the solution that the utility model is taked is: a kind of cutting mechanism of high speed clothes left front bead cutter, it comprises knife bar, needle plate, push pedal, pressing plate, presser feet, knife rest and cutting knife, knife rest divides upper tool post and lower slide, cutting knife divides upper slitter, middle cutter and following cutter, knife bar connects the upper slitter stand, upper slitter is plugged knife rest, on the upper tool post spring housing upper tool post, be installed in the upper slitter stand from the right side, middle cutter is installed in the needle plate front end, and following cutter is inserted lower slide, and the lower slide spring is installed between lower slide swing arm and the lower slide, the lower slide swing arm is fixed on swing seat left side, two guide pillars stretch into lower slide and insert the lower slide swing arm, and slide block snaps in the lower slide swing arm slide block slot from the right side, and lower shaft stretches into the lower slide eccentric wheel and inserts slide block.

The cutting mechanism of this high speed clothes left front bead cutter because knife bar connects the upper slitter stand, moves up and down, and drives upper tool post and upper slitter and makes stroke motion up and down, finish the upper slitter cutwork, and middle cutter is actionless.Lower shaft is done 360 degree rotations and is driven lower slide eccentric wheel and slide block, and the lower slide swing arm is moved up and down, and drives lower slide and following cutter and makes stroke motion up and down, finishes down the cutter cutwork.The cutting mechanism of this high speed clothes left front bead cutter adopts upper slitter, middle cutter and following cutter three cuttves to be used, and can cut the sheet up and down of left front and collar simultaneously.Upper tool post spring and lower slide spring all play very big effect in this cutting mechanism.On the upper tool post spring housing upper tool post, be installed in the upper slitter stand, just can do to regulate automatically, guarantee that upper slitter and middle cutter do not stay the gap, have improved the service life of cutting ability and upper slitter according to the wear extent of upper slitter from the right side.The lower slide spring is installed between lower slide swing arm and the lower slide, makes lower slide under the effect of lower slide spring, can do slight automatic adjusting work along guide pillar.Therefore, just the wear extent of cutter is done adjusting automatically under the energy basis, and cutter and middle cutter do not stay the gap under the assurance, have improved the service life of cutting ability and following cutter.
