Embodiment 2
[0048] Embodiment two, such as Figure 12 As shown: the main difference between the second embodiment and the first embodiment is: one is that one side of the bracket 40 is hinged on the frame 1, and the insertion movement mechanism is a swing cylinder 55; Mechanism 9 is installed on the plastic bag conveying device 3, and rib removal mechanism 9 is a kind of rib removal bar 91, and rib removal bar 91 is installed on the both sides of mechanical clamp 34, and two side positions of each side are respectively installed two rib removal bars. The rib bar 91 makes the space enclosed by the 4 rib bars 91 larger than the width of the struts 43 on both sides after being stretched; a hinged column 54 is installed on one side of the support 40 so that the support 40 passes through the hinged column 54 is hinged on the frame 1, and a swing cylinder 55 is installed on the hinge column 54 and the bracket of the frame 1, the vibration plate device 2 is installed on the front right side of t...
Embodiment 3
[0050] Embodiment three, the main difference of embodiment three is: as Figure 14 As shown, the U-shaped notch 21 is arranged obliquely; the bottom side support bar 42 is fixedly arranged on the bottom side of the bracket 40, corresponding to the bottom of the U-shaped notch 21; Side strut 41; a two-side strut 43 is installed at a position corresponding to the upper side strut 41 directly below, so that the two-side strut 43 corresponds to the bottom side strut 42 left and right, and also corresponds to the upper side strut 41 Corresponding up and down, so that a right-angled triangle is formed between the two side struts 43, the bottom side struts 42, and the upper side struts 41; The upper position of the upper side, and corresponding to the upper side strut 41 left and right, the two side struts 43, the upper side strut 41 are respectively connected with the strut cylinder 44, and the strut cylinder 44 is installed on the support 40 respectively.
