[0031] In the embodiment, the support includes first support 201 and second support 202, two first mounting brackets 2011 are arranged on the crossbeam of first support 201, the first mounting bracket 2011 bottom is respectively equipped with first paddle 2012, two second mounting brackets 2021 are arranged on the crossbeam of second support 202, the second mounting bracket 2021 bottom is respectively equipped with second paddle 2022, the installation direction of first paddle 2012 and second paddle 2022 is opposite, and two first paddles 2012 are arranged on the outside of two second paddles 2022, as Figure 2 As shown in the figure, the opposite direction poking of first paddle 2012 and second paddle 2022 can make two side-by-side bags 4 move to the outside, so as to separate two bags 4.

[0032] The bottom of the first bracket 201 and the second bracket 202 are respectively connected to the first base 203 and the second base 204. The surface of the second base 204 is provided with a slide rail 205. The bottom of the second bracket 202 is provided with a slider 206. The slider 206 is slidably connected to the slide rail 205. The slider 206 can drive the second bracket 202 to slide in the horizontal direction, so that the distance between the second bracket 202 and the first bracket 201 can be adjusted to adapt to bags 4 of different sizes, thereby achieving the most suitable distance for separating the bags 4.

[0033] The first bracket 201 and the second bracket 202 are provided with an adjustment structure, which can drive the first bracket 201 and the second bracket 202 to move in the vertical direction.

When passing through the separation mechanism 2, they first pass through the first bracket 201, and the bag 4 is transmitted forward. The nozzle on the bag 4 moves along the edge of the first paddle 2012, causing the bag 4 to swing in the same way. After the bag 4 is rotated a certain angle, the bag 4 is transmitted to the bottom of the second bracket 202. The nozzle on the bag 4 moves in the opposite direction along the edge of the second paddle 2022, so that the bag 4 returns to its original direction. The two bags 4 are separated and transmitted to the corresponding bag stacking channels through the second transmission mechanism 3.
