Lower rotating shuttle assembly (68) includes: main shaft (24) under bottom shuttle box (23), lower rotating shuttle, curved needle shaft (25), offset assembly (26), locating part (27), pulling needle wobble component (28), pulling needle swinging axle (29), pulling needle push rod (30), routing bar (31), group line Bracing strut (32), dial spool connecting rod (33), dial line bar fixture block (34), pulling needle bar (35), copper sheathing (36), crochet hook fixing piece (37), Copper sheet (38), four needle needle stands (39), shield needle (40), looper (41), pulling needle (42), lower rotating shuttle motor (43).
Trimming structure (69) include: needle plate (44), handwheel (45), upper head sensor (46), lower rotating shuttle sensor (47), Lifting sliding table (48), head fixture plate (49), cylinder (50), trimming mounting plate (51), guide rod fixed ring (52), trimming guide rod (53), trimming pressure spring (54), blade (55), tension disc (56), crimping offset plate (57).
Cutting structure (70) includes: to cut motor (58), motor mounting plate (59), belt wheel (60), belt (61), cut-off knife band Take turns (62), rotary knife axis (63), cut-off knife (64).
Head motor (65) in upper head driving shaft (2) connection, is connected to the motor with pulley drive mode;Upper head master Moving axis (2) installs handwheel can be with manual governing;Upper head driving shaft (2) rotation can drive shank (18) driving shank driving big Connecting rod (5) rotation;Two eccentric shafts are on upper head driving shaft (2);The shank of one shank driving big connecting rod (5) connection lower section Two connecting rods (9) are driven, bar drives two connecting rods (9) and big swing arm (7) to be connected on head transmission shaft (6), big swing arm (7) The other end connect with shank (18), put on rotation drive shank (18) slide up and down;Another needle of upper head driving shaft (2) The other end of bar driving big connecting rod (5) is connect with presser feet driving swing rod (10);Presser feet drives swing rod (10) and presser feet oscillating bar assembly (12) it is connected on drive shaft (13), equally drive drive shaft turns, presser feet oscillating bar assembly (12) and the dynamic pressure of presser bar connecting band Foot moves up and down, and forms a set of connecting rod driving.
Main shaft (24) is connect with power motor output shaft (43) under lower rotating shuttle, is driven with the kind of drive of belt pulley;Under Main shaft (24) connection offset assembly (26) and pulling needle wobble component (28) under rotating shuttle;Offset assembly (26) drives curved needle shaft (25) to turn It is dynamic, locating part (27) locking;Pulling needle wobble component (28) drives pulling needle swinging axle (29) operating;Pulling needle swinging axle (29) drive is pulled out Needle push rod (30) swings;It dials spool (33) and is fixed together with pulling needle bar (35) with line bar fixture block (34) are dialled;Pulling needle Hole insertion on bar (35) is connected and fixed pulling needle (42);Pulling needle (42) thus swings to form a circuit, and crochet hook is fixed Part (37) is driven by curved needle shaft (25) and is swung, so forming link motion.
In trimming structure (69), for head after having sewed, control system can give one electric signal of trimming cylinder solenoid valve, cut Line cylinder (50) starts to fall, and trimming fixed plate (51) and other all parts is driven to fall downwardly together;When crimping offset plate (57) line is pushed down after falling on needle plate (44), cylinder (50) continues to fall, and crimping offset plate (57) pushes down line from blade (55) two sides, Trimming pressure spring (54) by the pressure contractions of trimming fixed plate (51) and tension disc (56), causes line to be pressed in trimming guide rod (53) Between crimping offset plate (57) and needle plate (44), cylinder (50) band cutting blade (55) continues to fall, and blade (55) falls into needle plate (44) indentation, there, after blade (55) fall to a certain extent, line is withdrawn by sliding trackle, cylinder (50), trimming pressure spring (54) pressure Power release, tension disc (56) reset to reset condition, and guide rod fixed ring (52) locks trimming guide rod (53) end, play reset limit The effect of position.
Cutter structure (70) cuts motor (58) and is mounted on motor mounting plate (59), and motor mounting plate (59) is mounted on machine On casing (1), belt wheel (60) is connect with motor (58) is cut, and cut-off knife belt wheel (62) is mounted on rotary knife axis (63), belt wheel (60) (61) are connect with belt with cut-off knife belt wheel (62), cut-off knife (64) is mounted on rotary knife axis (63).So motor drives rotary knife Axis (63) rotation, cut-off knife follow rotary knife axis (63) to rotate, cut fabric.
After falling on minimum point under upper head shank (18), presser feet (20) is made to be pressed onto minimum point, adjusts shank drive link (5) it is close apart from needle plate (44) distance in minimum point, presser feet minimum point to guarantee this position presser feet, but does not suffer for angle.Main shaft (2) it rotates, so that shank (18) is moved to upper limit position, while unscrewing shank (18), transfer needle (21) and needle plate (44) distance. When eedle moves to lower limit position, needle plate (44) is infinitely got close to eedle (21).
When eedle (21) is down to lower limit position, the spacing of looper (41) needle point and eedle (21) is 2.6mm, main shaft (24) rotation makes shank (18) to be in most lower limit position, rotary hook needle stand (39) angle, back rotation looper (41), with eedle (21) spacing becomes larger;Conversely, then turning down.The spacing of looper (41) needle point and eedle (21) is adjusted to tighten fixation after 2.6mm Screw.Looper (41) and eedle (21) side clearance infinite approach adjust looper (41) to eedle (21) notch bottom, looper (41) It is synchronous with eedle (21) movement, it swings from left to right;
When eedle (21) declines from upper limit position, looper (41) point is got close to away from eedle (21) pinprick upper end, by dextrad Left swing is dynamic.Presser bar (19) is begun to swing up, and when adjustment, is first unclamped the fixed screw in driving bias, is rotated clockwise drive Dynamic bias, presser bar (19), which is swung up, to laten, on the contrary then shift to an earlier date.
Head zero-bit is to just, and head handwheel (45) makes shank (18) peak in rotation, to positive sensor positioning ring Indentation, there fastens upper head sensor (46) after extinguishing sensor indicator light in sensor detection interval;The sensing of lower rotating shuttle Device (47) is fixed on bottom shuttle box (23), so after head spindle (24) make crochet hook swing to front end under rotating, to just Sensor (47) extinguishes sensor (47) and fastens;Upper head can be fixed to lifting sliding table (48) and head fixture plate in advance (49) on, on the basis of the above head (65), by needle plate (44) hole to just descending rotating shuttle (66), on the basis of needle plate (44) hole, needle (21) consistent all around away from needle plate (44) hole, guarantee that needle (21) do not scratch needle plate (44) in dropping process.
It should be noted that needle and presser feet hole will also guarantee that four needles are all in needle plate hole and presser feet hole without scratching.
