Abstract
The invention belongs to sewing machine technology and specifically designs a moving tool holder (16) and two distance adjustable moving blade fixing bases (20) arranged on the moving tool holder. Moving blades (17) are arranged on the moving blade fixing bases which can cut down superfluous seaming material after being processed by a placket machine at one time according to different demands and can also pull down one of the moving blades (17) according to the demands to realize the function of a single blade. In the realization, a square gap is provided on a cover plate (2) and a fixed blade plate (3) for assembling a fixed blade (4) is arranged on the gap. A rectangular empty groove is provided at a corresponding position of a sewing machine head (1). Thus, the sewing machine head can avoid the moving blade (17) that cuts cloth downward. And the cloth cutting function is realized in a manner that a middle blade motor (5) controls the up-and-down motion of the moving tool holder (16) and the moving blades (17) via a connecting block. Simultaneously, a moving blade bracket (18) is provided with a hole. Thus, a tool holder guiding axis (19) can move up and down. And the moving tool holder (16) can be guaranteed to move up and down alternately along the correct direction.
Description
Technical field:
The invention belongs to sewing machine technique, particularly designed a kind of pair of cutter structure, it can be used on the muti needle chainstitch m/c and can realize the scalable of cutter distance.
Background technology:
Muti needle chainstitch m/c is a kind of left front that is used to process clothes neckline position such as T-shirt and a Sewing machines of specialized designs exploitation, and it can reduce manufacturing procedure, simplifies production technology, thereby effectively promotes operating efficiency.Generally speaking, muti needle chainstitch m/c adopts single cutter-type structure, and after making a length of cloth, cutter structure is started working, and the cloth of making is cut, and reaches the effect of open-neck collar mouth, and the left front that forms like this is referred to as french front.Along with the lifting of clothes diversified demand, the demand of positive left front also appears in the left front of T-shirt thereupon.The processing of positive left front only need be increased to original stitching distance a certain amount of; Again with cutting knife just cut can, if but adopt single cutter structure at this moment, the sewing that stays after will finding to cut is too much; Also need before the following process by hand too much sewing to be cut, so just influenced process velocity.The present invention just is based on the consideration of simplifying working process, and changes single cutting knife into two cutting knifes, and the unnecessary sewing in left front processing back is once cut, and reaches the effect of raising the efficiency.
Summary of the invention:
The objective of the invention is to design a kind of two cutter structures of adjustable distance, it is used for muti needle chainstitch m/c, can be disposable unnecessary sewing after the processing of incision left front, reach out the purpose of positive left front.
The present invention includes head of sewing machine 1, cover plate 2, stationary knife plate 3, stationary knife 4, middle cutter motor 5, rolling bearing 6, electric machine support 7, eccentric wheel 8, connecting rod 9, connecting axle 10, contiguous block 11, following air cylinder 12, spacing cylinder 13, limited block 14, tool axis 15, movable knife rack 16, moving knife 17, moving knife support 18, the knife rest axis of guide 19, moving knife holder 20; It is characterized in that having designed a movable knife rack 16; And designed the moving knife holder 20 of two adjustable distances that can be mounted thereto; And moving knife 17 is installed, disposable the cutting away of unnecessary sewing after can left front being processed according to different demands above that.The present invention mainly is the single cutter structure that has improved original muti needle chainstitch m/c, and it is designed to the cutting knife of two adjustable distances, thereby solves the problem that the unnecessary sewing in muti needle chainstitch m/c processing back of hilted broadsword structure can't disposable excision.And owing to the distance between two moving knife 17 can be regulated; So can cut different sewings according to different demands; Moving knife 17 also is easy to load and unload simultaneously; As long as one of them is removed, also can realize the effect of hilted broadsword, only need change stationary knife plate 3 simply just can realize such function.The present invention is achieved in that and on cover plate 2, cuts a tetragonal breach, places the stationary knife plate 3 that is used to install stationary knife 4 above that.In order to make moving knife 17 after cutting cloth, be unlikely to run into head of sewing machine 1, need get the dead slot of a strip shape in the relevant position of head of sewing machine 1.After head of sewing machine 1 is started working a period of time; The following air cylinder 12 drive tool axis 15 and the movable knife rack 16 that has moving knife holder 20 and moving knife 17 mounted thereto that are installed on the moving knife support 18 are down cut the cloth motion; When tool axis 15 arrived the position of limited block 14, following air cylinder 12 quit work, and spacing cylinder 13 is started working simultaneously; Cylinder axis is pressed in the middle of the limited block 14 together with contiguous block 11; At this moment, middle cutter motor 5 will be controlled pumping of movable knife rack 16, moving knife 17 and moving knife holders 20 through contiguous block 11, thus the function that cloth is cut in realization.
Movable knife rack of the present invention 16, moving knife 17 and moving knife holder 20 need be fastened on movable knife rack 16 on the tool axis 15 when pumping, and the direction of motion receives the restriction of the knife rest axis of guide 19 simultaneously.On moving knife support 18, open a hole, the knife rest axis of guide 19 can be moved up and down therein, can guarantee that movable knife rack 16, moving knife 17 and moving knife holder 20 can pump in correct direction simultaneously.
Description of drawings:
Fig. 1 is a mounting structure sketch map of the present invention;
Fig. 2 is head of sewing machine 1 axonometric drawing of the present invention;
Fig. 3 is knife rest 16 part sketch mapes of the present invention;
Fig. 4 is the scheme of installation of knife rest 16 of the present invention and moving knife holder 20;
Fig. 5 is the front view of part eccentric wheel 8 of the present invention,
Fig. 6 is stationary knife 4 scheme of installations of the present invention.
The specific embodiment:
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, will on cover plate 2, cut a tetragonal breach, place the stationary knife plate 3 that is used to install stationary knife 4 above that.Get the dead slot of a strip shape in the relevant position of head of sewing machine 1; Make it avoid the moving knife 17 toward incision cloth, after head of sewing machine 1 was started working a period of time, the following air cylinder 12 drive tool axis 15 and the movable knife rack 16 that has moving knife 17 and moving knife holder 20 mounted thereto that are installed on the moving knife support 18 were down cut the cloth motion; When tool axis 15 arrives the position of limited block 14; Following air cylinder 12 quits work, and simultaneously spacing cylinder 13 is started working, and cylinder axis is pressed in the middle of the limited block 14 together with contiguous block 11; At this moment, middle cutter motor 5 will pumping through contiguous block 11 control movable knife racks 16 and moving knife 17.Again middle cutter motor 5 is installed on the electric machine support 7; An eccentric wheel 8 is installed on motor shaft; The cylindrical of eccentric wheel 8 cooperates with the inner ring of rolling bearing 6; The outer ring of rolling bearing 6 cooperates with an end of connecting rod 9, and the other end of connecting rod 9 is connected with connecting axle 10, so just can drive contiguous block 11 through connecting axle 10.When central cutter motor 5 rotates,, can drive contiguous block 11 and pump, so just can reach drive movable knife rack 16 and do reciprocating motion up and down together with moving knife 17 through the effect of eccentric wheel 8.Simultaneously, need on moving knife support 18, open a hole, the knife rest axis of guide 19 can be moved up and down therein, can guarantee that movable knife rack 16 can pump in correct direction.
