[0031] Working principle: Before using this flat pocket winding device that is convenient for replacing the winding roller, it is necessary to first check the overall situation of the device to ensure that it can work normally. According to Figure 1 - Figure 7As shown in the figure, by inserting the fixed frame 202 into the inside of the fixed sleeve 201, at this time, the staff pulls the pull plate 207 to drive the moving frame 205 to slide inside the fixed box 203. At this time, the moving frame 205 slides outside the support rod 204, and the telescopic spring 206 contracts. The movement of the moving frame 205 drives the movement of the two groups of rotating rods 209. The movement of the rotating rod 209 pulls the insertion plate 208 to slide inside the fixed box 203.

Compared with the prior art, the plug-in method is more stable, effectively avoiding the phenomenon that the winding roller body 102 falls during operation, bringing practicality to the staff during use. By sliding the square rod 211 inside the rotating tube 210, at this time, the staff adjusts according to the length of the winding roller body 102. Then, the staff fixedly connects one end of the square rod 211 with the fixed sleeve 201. At this time, the staff rotates the knob rod 213 to fix the fixing hole 212, thus achieving the effect of quickly adjusting and fixing according to the length of the winding roller body 102, greatly increasing the applicable range of the device. Then, by starting the motor 214 to drive the winding roller body 102 to rotate and wind, it brings convenience to the staff during use;

[0032] By rotating the worm 303 to drive the rotation of the worm gear 304, the rotation of the worm gear 304 drives the rotation of the bidirectional screw 302. The rotation of the bidirectional screw 302 drives the moving sleeve 305 to move along a converging and expanding trajectory, thereby driving the relative movement of the moving plate 306. At this time, the through hole 307 is slidably connected to the winding roller body 102. Thus, the staff observes the moving plate 306 and the scale line 308, thereby achieving the effect of accurately adjusting the distance between the moving plates 306, and thus the effect of adjusting according to the width of the flat plastic bag, avoiding phenomena such as offset when the flat plastic bag is wound outside the winding roller body 102, and then enabling the device to be applicable to winding flat plastic bags of various specifications and widths, improving the quality of the wound flat plastic bags, and bringing convenience to the staff during use.
