Detailed Description

The following is further detailed by way of specific embodiments:

reference numerals in the drawings of the specification include: conveying roller 1, backup pad 2, bar groove 3, axis of rotation 4, mounting plate 5, locking piece 6, locking groove 7, supporting shoe 8, gear 9, bearing 10.

The first embodiment is as follows:

an embodiment substantially as shown in figure 1: the film drawing mechanism for the bag making device shown in fig. 1 comprises two conveying rollers 1 and two adjusting units, each adjusting unit comprises a supporting plate 2 and two adjusting parts, the supporting plate 2 is fixed with the ground through a bolt, and a strip-shaped groove 3 is formed in the supporting plate 2.

The equal coaxial welding of terminal surface at the both ends of transfer roller 1 has axis of rotation 4, and the diameter of transfer roller 1 is greater than the diameter of axis of rotation 4, and bar groove 3 is passed to axis of rotation 4, and axis of rotation 4 can slide from top to bottom in bar groove 3.

Each adjusting part comprises a fastening plate 5 and a locking piece 6, a through hole is formed in the fastening plate 5, the rotating shaft 4 is rotatably connected with the through hole, and a locking groove 7 is formed in the supporting plate 2; the locking piece 6 is a screw or a bolt, a threaded hole is formed in the fastening plate 5, and the screw or the bolt is in threaded connection with the bolt hole; when the locking piece 6 is a screw, the screw can be directly in threaded connection with the support plate 2; when the locking member 6 is a bolt, the bolt can contact and lock with the bottom and side walls of the locking groove 7.
