Detailed description of the invention
The following is specific embodiment of the utility model and in conjunction with accompanying drawing, the technical solution of the utility model is further described, but this utility model is not limited to these embodiments.
As it is shown in figure 1, this sewing machine includes head 1, presser bar fairlead 3, cutter bar 4, cutter driving bar 5 and Cutter apron 6.Presser bar fairlead 3, cutter bar 4 and cutter driving bar 5 longitudinally set gradually along head 1 from motion end to end.
Having installation cavity in head 1, presser bar fairlead 3 is positioned at the installation cavity of head 1, and presser bar fairlead 3 is vertically arranged, and the lower end of presser bar fairlead 3 is fixing with head 1 to be connected.Being equipped with a presser bar 2 in presser bar fairlead 3, the lower end of presser bar 2 is fixed with the presser feet being positioned on the downside of head 1.The side of presser bar fairlead 3 is provided with shank 7, and the upper-end part of driving of shank 7 is in the installation cavity of head 1, and the lower end of shank 7 is fixed with eedle.
Cutter bar 4 and presser bar 2 be arranged in parallel, and cutter bar 4 is through the lower wall of head 1, and the upper-end part of driving of cutter bar 4 is in the installation cavity of head 1.In order to improve cutter bar 4 kinematic dexterity and kinetic stability, sheathed axle sleeve 8 on cutter bar 4, axle sleeve 8 is fixed on head 1.
It is provided with guide holder 9 in the installation cavity of head 1, guide holder 9 has pilot hole and the first connecting hole that pilot hole be arranged in parallel and through the first contraction mouth of the first connecting hole and first bolt 10 hole vertically disposed with the first contraction mouth.Specifically, presser bar fairlead 3 penetrates in the pilot hole of guide holder 9, and cutter bar 4 penetrates in the first connecting hole of guide holder 9, is connected to the first bolt 10 at the first bolt 10 hole female thread, the first contraction mouth is forced to shrink by screwing the first bolt 10, it is achieved cutter bar 4 is fixing with guide holder 9 to be connected；It is more stable that this structure had both made cutter bar 4 move, and makes again cutter bar 4 not rotate simultaneously.Cutter bar 4 is eccentric rod, ensures between cutter bar 4 and presser bar fairlead 3 that in spacing and guide holder 9, between pilot hole and the first connecting hole, spacing adapts by screwing cutter bar 4 during assembling, it is ensured that cutter bar 4 elevating movement is flexibly and stable；In other words, cutter bar 4 adopts eccentric rod can be effectively reduced processing and the installation accuracy of all parts, thus has simple in construction, easy to assembly, the advantage of low cost of manufacture.
The lower end of cutter bar 4 is fixed with Cutter apron 6；Specifically, Cutter apron 6 has the second connecting hole and through the second contraction mouth of the second connecting hole and second bolt 11 hole vertically disposed with the second contraction mouth；The lower end of cutter bar 4 penetrates the second connecting hole of Cutter apron 6, can ensure that cutting knife is parallel with cutting blade on needle plate by rotary cutting tool rest 6, it is ensured that cut cloth efficiency.It is connected to the second bolt 11 at the second bolt 11 hole female thread, passes through to screw the second bolt 11 after being adjusted in place and force the second contraction mouth to shrink, it is achieved cutter bar 4 is fixing with Cutter apron 6 to be connected.
The upper-end part of driving of cutter driving bar 5 is in the installation cavity of head 1, and the lower end of cutter driving bar 5 is fixed with the clutch 12 that can combine with Cutter apron 6 or separate.Having clutch hole on Cutter apron 6, when the trip(ping) lever of clutch 12 penetrates in clutch hole, cutter driving bar 5 drives Cutter apron 6 and cutter bar 4 lifting to move back and forth.When the trip(ping) lever of clutch 12 is in released state with Cutter apron 6, Cutter apron 6 and cutter bar 4 remain stationary as；In order to avoid cutting knife affects cloth wheel feeding, being arranged with a spring 13 on cutter bar 4, one end of spring 13 and guide holder 9 lean, and the lower wall of the other end of spring 13 and head 1 leans；Namely, when the trip(ping) lever of clutch 12 is in released state with Cutter apron 6, when cutter bar 4 is automatically moved up under the elastic force effect of spring 13 and ensures the 5 reciprocal elevating movement of cutter driving bar, clutch 12 will not be touched with Cutter apron 6.
