1 for being preceding hanging feet, 3 for Sewing machines casing, 2, being that back hanging feet, 4 is last axle among the figure.
The specific embodiment:
Further specify embodiment of the present utility model below in conjunction with accompanying drawing:
The front and back of two groups of cam links control support teeth are installed respectively on 4 and move up and down at axle on the common chain type Sewing machines that is used for flush joint, one group is feeding cam connecting rod (referring to Fig. 1,2), and another group is tooth lifting cam connecting rod (referring to Fig. 1,3).Described feeding cam connecting rod is that an end of a feeding eccentric cam 12 and feeding connecting rod 13 is connected with last axle 4 through bearing 131, the other end of feeding connecting rod 13 is adjusted crank 14 by oscillating bearing 132 through screw 141 and feeding and is connected, one feeding crank axle 11 is fixed on the preceding hanging feet 2 of casing 3 through hanging feet axle sleeve 111, the two ends of this feeding crank axle 11 are adjusted crank 14 through screw 142 and 151 with feeding respectively and are linked to each other with feeding crank 15, one feeding is adjusted crank 14 and is linked to each other with last axle 4 with oscillating bearing 131 through feeding connecting rod 13, fall and be connected with feeding crank 15 with screw 163 through oscillating bearing 161 along adjusting rod 16 1 ends, fall suitable adjusting rod 16 other ends through being connected with support tooth bar 17 with screw 164 through oscillating bearing 162, and support tooth bar 17 links to each other with the support tooth crank 18 that is connected with support tooth 20; Described tooth lifting cam connecting rod is to lift tooth eccentric cam 22 to be connected with last axle 4 through bearing 231 with an end of lifting tooth connecting rod 23, the other end of lifting tooth connecting rod 23 is lifted tooth through oscillating bearing 232 and screw 241 and and is adjusted crank 24 and be connected, one lift tooth adjust crank axle 21 through hanging feet axle sleeve 211 be fixed in casing 3 after on the hanging feet 3, this lift a end that tooth adjusts crank axle 21 through screw 242 with lift tooth adjustment crank 24 and be connected, the other end is connected with feed lifting rock shaft crank 25 through screw 251, this feed lifting rock shaft crank 25 is regulated connecting rod 26 and is linked to each other with lifting tooth through oscillating bearing 252, lift tooth regulate connecting rod 26 other ends through oscillating bearing 261 and screw 262 be connected with the support tooth crank 18 that supports tooth 20 and link to each other.One support tooth 20 is installed on below the presser feet before the suture needle.
During work, last axle 4 and eccentric cam 12 are fixing, last axle 4 rotates and drives eccentric cam 12 rotations, thereby promote feeding by 13 reciprocating motions of feeding connecting rod and adjust crank 14, because crank 14 is adjusted in feeding and the 15 fixing and same feedings of feeding crank are adjusted on the crank axles 11, the swing of feeding crank 15 makes support tooth bar 17 drive below presser feet before the suture needle support tooth 20 thereupon swinging cloth is sent forward.Meanwhile, being installed on the same eccentric cam of going up on the axle 4 22 also rotates because of last axle 4 rotates drive eccentric cam 22, thereby promote to lift tooth adjustment crank 24 by lifting tooth connecting rod 23, tooth is adjusted crank 24 and feed lifting rock shaft crank 25 is fixed in same lifting on the tooth adjustment crank axle 21 owing to lift, the swing that the platform tooth is adjusted crank 24 makes moving up and down of feed lifting rock shaft crank 25, drive simultaneously and lift that tooth is regulated connecting rod 26 and support tooth crank 18 moves up and down, make support tooth 20 will support tooth forward during the work feed material and down be pressed in and finish a preceding feeding and move the back brace tooth and draw back; Do and will support tooth when feeding is next time prepared and up lift, the ground warp that so goes round and begins again support tooth will excessive cloth is rigid be sent into the formation accumulation, thereby produces one stupefied one stupefied wavyly, realizes pleating making.
