The specific embodiment
As Fig. 1, shown in Figure 2, the embodiment of the feed mechanism of portable bag closer of the present utility model, comprise main shaft 1, casing 10, eccentric shaft 3, feeding slide block 4, following retainer 5, horizontal limit shaft 6, vertical spacing axle sleeve 7 and vertical fixed axis 8, feeding slide block 4 is provided with the feeding slide block through hole 4a of horizontal direction, main shaft 1 is installed in the casing 10 by bearing 13, eccentric shaft 3 one ends and 1 eccentric connection of main shaft, eccentric shaft 3 other ends are arranged in feeding slide block 4 installing holes rotationally, following retainer 5 is installed on the feeding slide block 4, following retainer 5 is positioned at the upper end of feeding slide block 4, vertical spacing axle sleeve 7 is enclosed within vertically sliding up and down on the vertical fixed axis 8 and along vertical fixed axis 8, horizontal limit shaft 6 one ends are connected on the vertical spacing axle sleeve 7, horizontal limit shaft 6 other ends penetrate feeding slide block through hole 4a, and horizontal limit shaft 6 is perpendicular to vertical spacing axle sleeve 7 and vertical fixed axis 8.Thereby aforesaid main shaft 1 rotates and drives eccentric shaft 3 motions, drives feeding slide block 4 and 5 motions of following retainer by eccentric shaft 3 again.But, because eccentric shaft 3 is when driving feeding slide block 4 and 5 motions of following retainer, also can produce the rotation of relative feeding slide block 4, in order not allow feeding slide block 4 with together rotation of eccentric shaft 3, by horizontal limit shaft 6, vertical spacing axle sleeve 7 and vertical fixed axis 8 are converted into the rotation of feeding slide block 4 along the axial horizontal slip of horizontal limit shaft 6, make feeding slide block 4 and following retainer 5 remain level, what produce when feeding slide block 4 slides on horizontal limit shaft 6 is the sliding friction of face contact, can reduce the wearing and tearing of feed mechanism greatly, and feed mechanism is operated steadily, thereby the beneficial effect in the service life that is improved.
Extremely shown in Figure 7 as Fig. 2, also be provided with on the main shaft 1 in the said structure wheel 2 is installed, eccentric shaft 3 is by installing wheel 2 and 1 eccentric connection of main shaft, eccentric shaft 3 one ends are provided with dovetail guide 3a, wheel 2 is installed is provided with dovetail guide groove 2a, dovetail guide 3a on the eccentric shaft 3 is installed among the dovetail guide groove 2a, eccentric shaft 3 is axially arranged with the fastening screw 3b of perforation, trip bolt 12 cooperates fastening screw 3b, make dovetail guide 3a be adjacent to dovetail guide groove 2a, thereby rely on the frictional force on dovetail guide 3a and the dovetail guide groove 2a inclined-plane that eccentric shaft 3 is fixed on the desired location that wheel 2 is installed.Because eccentric shaft 3 is installed the adjustment that the adjustment of wheel 2 positions can drive feeding slide block 4 and be installed in following retainer 5 relative main shafts 1 position on the feeding slide block 4 relatively, but thereby the regulatory function of suture needle gage when realizing sewing, further bring can be in predefined scope the beneficial effect of free adjustment needle gage.
As Fig. 2, Fig. 8, Fig. 9, Figure 10 and shown in Figure 11, also be provided with the following retainer fixing hole 5a that runs through on the retainer 5 down, feeding slide block 4 is provided with the longitudinal spacing groove 4c that cooperates with following retainer 5 corresponding sites, feeding slide block 4 is provided with positioning screw hole 4b, dog screw 11 is tightened onto among the positioning screw hole 4b after passing down retainer fixing hole 5a, dog screw 11 heads are then stopped by following retainer 5 and can not pass through retainer fixing hole 5a down, thereby will descend retainer 5 to be pressed among the longitudinal spacing groove 4c of feeding slide block 4, because the hole inner height size of following retainer fixing hole 5a is greater than the diameter of dog screw 11, unclamp dog screw 11 and can regulate down the upper-lower position of retainer 5 in longitudinal spacing groove 4c, thereby regulate the operating position height of retainer 5 down, to adapt to the packaging material of different-thickness.
