The utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of drawing mechanism of shoemaking sewing machine comprises that the feeding parts are arranged on the drive rod of lift cylinder for the feeding parts of crawl material; Lift cylinder slides and is located on the hold-down arm, and drives by reciprocating air cylinder.
For optimizing technique scheme, the utility model also comprises following improved technical scheme.
Above-mentioned hold-down arm is shaped with the adjusting mounting groove, is provided with the mount pad that can adjust the installation site by regulating mounting groove; Mount pad is fixed with the translation guide rail, and lift cylinder is slidingly matched by translation slide block and translation guide rail.
Above-mentioned reciprocating air cylinder is fixedly connected with mount pad, and the drive rod of reciprocating air cylinder is connected with lift cylinder.
Above-mentioned lift cylinder is fixed on the cylinder mount pad, and the cylinder mount pad is fixedly connected with the translation slide block.
Above-mentioned cylinder mount pad is fixed with riser guide, and the feeding parts are connected with lifting slider on the riser guide.
Above-mentioned feeding parts are sucker or pressing plate.
Compared with prior art, the utility model drawing mechanism can after the shoemaking sewing machine sewing is finished, drive feeding parts crawl material by lift cylinder, then drive lift cylinder along the translation guide rail movement to the discharging position by reciprocating air cylinder, automatically material is shifted out the sewing zone.
Description of drawings
Fig. 1 is the perspective view of the utility model embodiment.
Fig. 2 is the assembling decomposing schematic representation of the drawing mechanism among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is to Figure 2 shows that structural representation of the present utility model.
Reference numeral wherein is: feeding parts 1, lift cylinder 2, cylinder mount pad 21, riser guide 22, lifting slider 23, hold-down arm 3, adjusting mounting groove 31, mount pad 32, translation guide rail 33, translation slide block 34, reciprocating air cylinder 4.
The drawing mechanism of shoemaking sewing machine as depicted in figs. 1 and 2 comprises that feeding parts 1 are arranged on the drive rod of lift cylinder 2 for the feeding parts 1 of crawl material.Lift cylinder 2 slides and is located on the hold-down arm 3, and drives its slip by reciprocating air cylinder 4.
Be shaped with adjusting mounting groove 31 at hold-down arm 3.In the present embodiment, hold-down arm 3 has two, and first hold-down arm 3 vertically is fixed on the frame, and second hold-down arm 3 is horizontally disposed with and is fixedly connected with first hold-down arm 3.Can adjust the installation site by regulating mounting groove 31 and fixture between first hold-down arm 3 and second hold-down arm 3.
The hold-down arm 3 of level is provided with the mount pad 32 that can adjust the installation site by regulating mounting groove 31.The bottom of mount pad 32 is provided with and can snaps in the fixture of regulating mounting groove 31, adjust the position of mount pad 32 after, by screw fixture is fixedly connected with adjusting mounting groove 31.
Be fixed with translation guide rail 33 on the mount pad 32, lift cylinder 2 is slidingly matched by translation slide block 34 and translation guide rail 33.
Reciprocating air cylinder 4 is fixedly connected with mount pad 32 by support, and the drive rod of reciprocating air cylinder 4 is connected with lift cylinder 2, can drive lift cylinder 2 integral body and move along translation guide rail 33.
Lift cylinder 2 is fixed on the cylinder mount pad 21, and cylinder mount pad 21 is fixedly connected with translation slide block 34, and slides along translation guide rail 33 under reciprocating air cylinder 4 drives.
Cylinder mount pad 21 is fixed with riser guide 22, and feeding parts 1 are connected with lifting slider 23 on the riser guide 22.
Feeding parts 1 are sucker or pressing plate.Drive at riser guide 22, feeding parts 1 move downward, and then the crawl material under reciprocating air cylinder 4 drives, makes material shift out the sewing zone.
Most preferred embodiment of the present utility model is illustrated, and various variations or the remodeling made by those of ordinary skills can not break away from scope of the present utility model.
