Detailed description of the invention
Below in conjunction with accompanying drawing, by specific embodiment, clear, complete description is carried out to the technical solution of the utility model.
Refer to shown in Fig. 1, the utility model provides a kind of grabbing device for tubular stocking machine, for capturing circular knit hosiery to be stapled to suture location, comprise crochet hook 11, needle-bar 12, impeller 13 and contraction spring 14, described needle-bar 12 ringwise, described needle-bar 12 is provided with several accepting groove 121 circumferentially distributed, described crochet hook 11 is contained in accepting groove 121 and also can moves along accepting groove 121, several crochet hook 11 circumferentially distributes, described impeller 13 is resisted against the inner side of several crochet hook 11 for being promoted outward by crochet hook 11, described contraction spring 14 is looped around the outside of several crochet hook 11, for promoting crochet hook 11 toward interior movement." outside " described in literary composition is the outside of the annulus annulus for several crochet hook 11 formation, and " inner side " is the inner side of the annulus annulus for several crochet hook 11 formation.
Refer to shown in Fig. 1, described grabbing device 1 also comprises to be located at outside needle-bar 12 for accommodating the snap ring portion 15 of needle-bar 12, be located at the adapter plate 16 above snap ring portion 15, be located at the drive plate 17 above adapter plate 16, this drive plate 17 is provided with several by interior arc-shaped through-hole 171 outwardly, pin 18 connects impeller 13 through after this arc-shaped through-hole 171, described drive plate 17 is electrically connected motor (not shown), under the drive of motor, drive plate 17 along own axis, drive plate 17 to rotate and drive pin 18 to move outward in through-holes, thus drive impeller 13 to move outward, and then promotion crochet hook 11 moves outward.
Refer to shown in Fig. 2, described impeller 13 comprises several end to end fan-shaped annular portion 131, the head end 132 of each fan-shaped annular portion 131 is provided with the first opening upward, tail end 133 is provided with the second opening down, first opening of the head end 132 of arbitrary fan-shaped annular portion 131 is relative with the second opening of the tail end 132 of another fan-shaped annular portion 131, and the head end 132 of arbitrary fan-shaped annular portion 131 can relatively adjacent fan-shaped annular portion 131 tail end 133 near or remotely slide, thus impeller 13 can expand or reduce inward the girth of excircle outward.When several fan-shaped annular portion 131 is relatively away from slip, impeller 13 expands outward thus promotes crochet hook 11 and moves side outward.The head end 132 of arbitrary fan-shaped annular portion 131 is contained in the second opening of another fan-shaped annular portion 131, the tail end 133 of arbitrary fan-shaped annular portion 131 is contained in the first opening of another fan-shaped annular portion 131, and the degree of depth of described first opening is identical with the thickness of the tail end 133 of fan-shaped annular portion 131; The degree of depth of described second opening is identical with the thickness of the head end 132 of fan-shaped annular portion 131, thus can ensure the smooth of the upper and lower surface of impeller 13.Described fan-shaped annular portion 131 is provided with through hole, connects pin 18, controlled the movement of each fan-shaped annular portion 131 of impeller 13 by pin 18 by through hole.
Refer to shown in Fig. 3, described crochet hook 11 comprises bar portion 111, is located at the hook portion 112 of one end, described bar portion 111 and is located at the afterbody 113 of described bar portion 111 other end, and the free end of described afterbody 113 bends towards described hook portion 112.Described impeller 13 is resisted against the afterbody 113 of crochet hook 11, and impeller 13 promotes afterbody 113 and drives whole crochet hook 11 to move outward.Described afterbody 113 is provided with square groove 114 near the one end in described bar portion 111, and described contraction spring 14 is resisted against in this groove 114, because the elastic reaction of contraction spring 14 can oppress crochet hook 11 from outside, thus makes crochet hook 11 can from outside toward medial movement.
Described needle-bar 12 comprises annular bottom plate 122 and is located at the annular resettlement section 123 on this annular bottom plate 122, and described annular bottom plate 122 is located at below snap ring portion 15, and described annular resettlement section 123 is contained in snap ring portion 15.Described resettlement section 123 comprises the first collecting section, the second collecting section and the 3rd collecting section that connect successively, and described resettlement section 123 is provided with described accepting groove 121, the through first collecting section of each accepting groove 121, the second collecting section and the 3rd collecting section.Described accepting groove 121 is for accommodating crochet hook 11, and crochet hook 11 can move along described accepting groove 121, and namely crochet hook 11 can move in the accepting groove 121 in the first collecting section, the second collecting section and the 3rd collecting section.
The specific works process that the utility model is used for the grabbing device of tubular stocking machine is: grabbing device moves to knitting position, crochet hook 11 inserts the coil that below crochet needle, hook is got on socks, electric machine control drives plate 17 along own axis, drive plate 17 to rotate and drive pin 18 to move outward in arc-shaped through-hole 171, thus drive impeller 13 to move outward, and then promote crochet hook 11 mobile hook stringing circle outward.
In sum, the utility model is used for the grabbing device of tubular stocking machine, be provided with the crochet hook of the coil capturing circular knit hosiery undertoe to be stapled, crochet hook is contained in needle-bar, the inner side of crochet hook and outside arrange impeller and contraction spring respectively, crochet hook is controlled outward or toward interior movement from impeller and contraction spring, thus capture the coil of circular knit hosiery undertoe to be stapled, the coil one_to_one corresponding of crochet hook and circular knit hosiery undertoe, thus this grabbing device can capture circular knit hosiery to be stapled quickly and accurately, facilitate follow-up sewing work, effectively can improve the production efficiency of socks.
