A kind of sewing machine with clamping-line structure of the present invention, including sewing machine head 1 and sewing control system.
The side of sewing machine head 1 is installed with magnet driver 2, and the drive rod of magnet driver 2 is connected to the clamp hook 23 for clamping the end of a thread.Adopt magnet driver 2 to carry out clamp driving, have and be easy to control, react quick, clamp advantage accurately.
The opposite side of sewing machine head 1 is fixed with installing rack 4, and installing rack 4 is fixed with hook line cylinder 5, and the drive rod of hook line cylinder 5 is connected to the guy hook 53 for the end of a thread is pulled to clamp hook 23 place.Hook line cylinder 5 is adopted to carry out hook line operation, the advantage have hook lineal travel length, being easy to design and installation.When suture is not cut off smoothly, hook line cylinder 5 is because having elastic stroke, without affecting subsequent operation.Hook line cylinder 5 is compared to by solenoid actuated hook line, and electric magnet has the shortcoming driving stroke short, when suture is not cut off smoothly, also can carry out hook line operation in the same old way, and pullling the suture on eedle can affect sewing efficiency.
Sewing control system has the bracing wire control module that control hook line cylinder 5 drives guy hook 53 to work when eedle suture carries out trimming and drives the clamp that the end of a thread clamped by clamp hook 23 to control module with controlling magnet driver 2.Bracing wire controls module and controls the duty of hook line cylinder 5.Clamp controls module and controls the duty of magnet driver 2.
It is shaped with the bottom table top for fixing clamp installing rack 3 near shank place in the bottom of sewing machine head 1.Clamp installing rack 3 is fixed with guide plate 31, and guide plate 31 is provided with the clamp block 32 for coordinating clamp hook 23 clamp.
The side of sewing machine head 1 is shaped with the installation table top 1a perpendicular with bottom table top.Table top 1a is installed and is shaped with the installing hole 11 for fixing clamp mounting seat 21.Magnet driver 2 is fixed in clamp mounting seat 21.
Magnet driver 2, clamp block 32 and hook line cylinder 5 are distributed in each position of sewing machine head 1, facilitate bracing wire and clamp, can effectively utilize the installing space of sewing machine head 1 simultaneously, will not the original eedle of sewing machine, thread take-up tension lever and feed mechanism be interfered.
Guide plate 31 is fixed with clamp and installs axle 33, and what clamp block 32 can rotate is arranged on clamp installation axle 33.The bottom of clamp block 32 is shaped with the clamp groove 32a that can snap in clamp hook 23.Clamp hook 23 has and the clamp groove 32a hook portion 23a matched.
The clamp that is arranged on that can rotate due to clamp block 32 is installed on axle 33, and when hook portion 23a snaps in clamp groove 32a, clamp block 32 can adjust attitude automatically, makes hook portion 23a coordinate with clamp groove 32a and is fixed by suture.
Guide plate 31 is shaped with gathering sill 31a, and clamp hook 23 is fixedly installed axis of guide 23b, and axis of guide 23b is slidably arranged in gathering sill 31a.Guide plate 31 both played install clamp block 32 effect, play again clamp hook 23 guiding make to, it is possible to make clamp operation more stable, clamp accuracy rate is higher.
Installing rack 4 has attaching clamp 4a, plate portion 4b, base plate 4c, mounting lug portion 4d and switch protruding pinna 4e.Lug 4a, plate portion 4b, base plate 4c, mounting lug portion 4d and switch protruding pinna 4e are made up of one piece of metallic plate entirety bending, have easy to make, it is simple to the advantage of installation.
Mounting lug portion 4d is fixed with crank mounting seat 41, and crank mounting seat 41 is provided with the crank 52 that can rotate.The crankshaft 52a of crank 52 one end rotates and is arranged in crank mounting seat 41 and is connected with guy hook 53, and the crank drive shaft 52b of the other end and crank pull bar 51 are rotationally connected.The drive rod of hook line cylinder 5 is connected with drive seat 55, and the other end of drive seat 55 and crank pull bar 51 is rotationally connected.
When the drive rod of hook line cylinder 5 stretches, pulling crank drive shaft 52b by crank pull bar 51, make crank 52 rotate around crankshaft 52a, the suture on eedle from inswept between eedle and needle plate, can be hooked and be pulled to clamp hook 23 place by the end of guy hook 53.
Crankshaft 52a is fixedly connected with guy hook and connects seat 54, and guy hook 53 has a regulating tank, and is connected seat 54 with guy hook by regulating tank and is connected, and can be adjusted the installation length of guy hook 53 by regulating tank.
The end of guy hook 53 has the wire casing 53a for snapping in suture.When guy hook 53 motion is streaked bottom eedle, just can by suture card leading groove 53a, it is possible to prevent suture in hook line process from departing from guy hook 53.
Hook line cylinder 5 is provided with the sensor 6 for detecting cylinder stroke.When hook line cylinder 5 does not have smooth hook line, the drive rod of hook line cylinder 5 is also without reaching set stroke.Sewing control system has reception sensor 6 and detects the detection processing module of signal, sensor 6 detects when hook line cylinder 5 does not complete impulse stroke, detection processing module just controls module to clamp and sends the control instruction suspending clamp, and now clamp controls module and just will not control magnet driver 2 and work.
Highly preferred embodiment of the present invention illustrates, those of ordinary skill in the art the various changes made or remodeling are all without departing from the scope of the present invention.
