[0040] As a technical optimization solution of the utility model, the pressing block 7 is in a conical shape;

[0041] It can be seen from the above description that the conical shape can well control the pressing block 7 to enter the opening 9.

[0042] Working principle:

[0043] When folding plastic bags of corresponding sizes, first control the positions of the fixing plate 15 and the fixing plate 2 19 by using the knob 1 20 and the knob 2 21, then align the conveying device of the plastic bag with the workbench 1 or manually place the plastic bag on the workbench 1 directly. When the plastic bag enters the workbench 1, the worker only needs to press the control button 2 to control the electric hydraulic rod 4 to work, so that the plastic bag enters the opening 9, and finally enters the storage box 13 in a folded state through the arc guide tube 12, and is stacked layer by layer, thereby ensuring the efficient folding of the plastic bag.
