The upper side of the cutter head is provided with a cutter frame, and the static blade is arranged on the cutter frame; and a pressure lever capable of extruding the static blade is arranged on the static blade.
Two cylinders are arranged on the cutter head, and piston rods of the two cylinders are respectively connected with two ends of the cutter pushing rod.
And a limiting block matched with the push broach rod is arranged on the cutterhead.
After the structure is adopted, compared with the prior art, the utility model the advantage that has is: the utility model is provided with the holding cavity on the cutter head, and the layout matched with the roller can be assembled in the holding cavity, so that the assembly layout of the thread trimming device on the sewing machine and other accessories is more compact and reasonable when the sewing machine is produced and assembled; the device has the advantages of simple structure, quick and accurate thread trimming and high efficiency.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The following description is only for the preferred embodiment of the present invention, and the protection scope of the present invention is not limited thereby, the present invention will be further explained with reference to the drawings and the embodiments.
Example, see figure 1: a thread trimming device on a sewing machine comprises a cutter head 1, a push-type cutter rod 2, a static blade 3, a movable blade 4 and a cylinder 5.
A wire window 8 is arranged on the cutter head 1, a suture can pass through the wire window 8, and a sliding groove 9 is arranged on the cutter head 1 on the upper side of the wire window 8; a knife rest 10 is installed on the upper side of the knife disc 1, a plurality of groups of installation screw holes 11 are formed in the knife rest 10, a plurality of static blades 3 are installed on the plurality of groups of installation screw holes 11 through bolts, the static blades 3 point to the direction of the linear window 8, a pressure rod 12 capable of extruding the static blades 3 is arranged on the static blades 3 in a covering mode, and the action of the pressure rod 12 is that the matching tightness of the static blades 3 and the movable blades 4 can be kept; the utility model discloses a blade pushing device, including blade pushing rod 2, blade disc 1, stopper 13, blade pushing rod 2 and stationary blade 3, blade pushing rod 2 installs in spout 9 and can follow stationary blade 3's sensing direction and make a round trip to slide, install a plurality ofly on the blade pushing rod 2 and stationary blade 3 complex movable blade 4, be provided with on the blade disc 1 with blade pushing rod 2 complex stopper 13, stopper 13 can restrict blade pushing rod 2.
Install two cylinders 5 on blade disc 1, the piston rod of two cylinders 5 is connected with the both ends of push-type broach pole 2 respectively, and cylinder 5 is used for promoting push-type broach pole 2 and makes a round trip to slide along the direction of orientation of static blade 3.
The lower end of the tool bit of the movable blade 4 is a tip, two sides of the tip are arc-shaped edges, and the arc-shaped edges are respectively provided with a knife edge matched with the fixed blade 3. When the thread cutting device on the sewing machine works, the cutter bar 2 slides downwards under the action of the air cylinder 5, the cutter head of the movable blade 4 penetrates through the thread in the thread window 8 and then the cutter bar 2 slides upwards under the action of the air cylinder 5, and when the cutter head slides upwards, the cutter edge of the movable blade 4 hooks the thread and finally is matched with the fixed blade 3 to cut the thread. The device has the advantages of simple structure, quick and accurate thread trimming and high efficiency.
