[0019] In the present application, when it is used specifically, the sealing zipper is installed on the self-sealing strip opened in the PE zipper bag, and the article is placed inside the PE zipper bag, and then the self-sealing strip is sealed by the sealing zipper, and then the pin is inserted into the plug hole opened on one side of the sealing zipper, and then it is sealed with hot melt adhesive. At this time, the pin will be inserted into the easy-tear line opened. When the PE zipper bag needs to be opened, the sealing zipper is pulled, and the pin of the sealing zipper will tear it along the easy-tear line. When it is found that the part above the easy-tear line falls off or is torn, it can be found that the article has been opened, and it can be replaced in time and avoided. Since the easy-tear line is located above the self-sealing strip, the PE zipper bag can still be used multiple times after the easy-tear line falls off;

[0020] When the zipper bag is transferred to the No. 1 cutting table through the conveyor belt, the No. 1 servo motor is started, and the output shaft of the No. 1 servo motor drives any roller to rotate, and the roller drives the rollers of the same group to rotate in the opposite direction through the connecting gears, and the zipper bag is driven forward by the clamping and rolling of the two rollers, and the rollers of another group are driven to perform the same movement through the synchronous belt. When the zipper bag moves onto the No. 1 cutting table and the No. 2 cutting table (the size between the two cutting knives is the size of the zipper bag to be cut, and the same size of cutting range is left after passing the second cutting knife, so two can be cut at a time through the two cutting knives), then the No. 2 servo motor is started, and the No. 4 gear on the outer wall of the No. 2 servo motor output shaft drives the No. 1 gear to rotate, and the No. 1 gear drives the No. 3 outer ring to rotate, and the No. 3 outer ring drives the No. 1 connecting shaft Rotate, the No. 1 connecting shaft drives the No. 1 outer ring to rotate (because one end of the No. 1 connecting rod is rotatably set at the eccentric position of the No. 1 outer ring, and the other end of the No. 1 connecting rod is rotatably set at the top of the cutting knife, and the cutting knife is slidably set inside the pressure block, and the pressure block is limited by the No. 1 limit frame and can only move vertically up and down), so that the No. 1 outer ring drives the cutting knife to move up and down through the No. 1 connecting rod when it rotates, so as to cut it, and at the same time, the two ends of the telescopic rod are respectively rotatably set at the eccentric positions of the No. 3 outer ring and the No. 2 outer ring, so that when the No. 3 outer ring rotates, it drives the No. 2 outer ring to rotate, the No. 2 outer ring drives the No. 2 connecting shaft to rotate, the No. 2 connecting shaft drives the No. 4 outer ring to rotate, and the No. 4 outer ring drives another cutting knife to perform the same movement through the No. 2 connecting rod, so that two can be cut at a time;

[0021] The specific cutting method of the cutting knife is that when it moves downward, it drives the pressing block to move downward. When the pressing block presses the zipper bag, the compression spring is squeezed, so that the cutting knife continues to move downward to cut the zipper bag, so that the zipper bag is fixed before cutting to avoid movement.

[0022] When the cutting size needs to be adjusted, first release the bolts on the telescopic rod to release the telescopic fixed state, then rotate the threaded rod, the threaded rod can drive the U-shaped frame to move, the U-shaped frame drives the No. 2 mounting block and the No. 2 limit frame to move, the No. 2 mounting block and the No. 2 limit frame drive the middle cutting knife and other parts to move, when adjusted to the appropriate distance, stop rotating, and fix the telescopic rod in the telescopic state with bolts to complete the adjustment of the cutting size.

[0023] In the utility model, the PE frosted zipper bag and cutting equipment are provided with an easy-tear line at the opening of the PE zipper bag and a pin is inserted inside the sealing zipper, so that when the PE zipper bag needs to be opened, the pin inside the sealing zipper will tear off the upper part of the easy-tear line to prevent others from opening it at will, thereby ensuring its safety. Moreover, since the self-sealing strip is provided below the easy-tear line, the PE zipper bag can be reused.

[0024] In the utility model, the PE frosted zipper bag and cutting equipment can achieve the goal of starting a No. 1 servo motor through a driving assembly, and the output shaft of the No. 1 servo motor drives the No. 1 outer ring to rotate. Through the eccentric setting of one side of the No. 1 outer ring and the cooperation of the No. 1 limit frame, the No. 1 outer ring drives the cutting knife to move up and down reciprocatingly when rotating, and cuts the zipper bag that needs to be cut, and drives the cutting knife of another group to perform the same movement through the same eccentric setting, so as to perform cutting on both sides, thereby increasing the effect;

[0025] In the utility model, the PE frosted zipper bag and cutting equipment can achieve that when the driving component drives the cutting knife to cut, the pressing block outside the cutting knife will press and fix the zipper bag to be cut below, and the cutting knife will continue to move downward to cut, thereby avoiding the problem of deviation during cutting;

[0026] In the utility model, the PE frosted zipper bag and cutting equipment can achieve the goal of releasing the fixed state of the telescopic rod by adjusting the components, and then rotating the threaded rod to drive another set of cutting knives to move, thereby adjusting the cutting size, and then re-fixing the telescopic rod in the telescopic state by bolts or the like;

[0027] In the utility model, when in use, through the design of the easy tear line and the insertion pin, when the PE zipper bag needs to be opened, the upper part of the easy tear line will be torn off to remind the customer that the package has been opened, and because the self-sealing strip is located below the easy tear line, the PE zipper bag can still be reused;

[0028] Two cutting knives are used to perform two cuts at a time, and one of the cutting knives can be moved by the adjusting component to adjust the cutting size of the zipper bag to avoid the problem that the traditional method can only cut once or the cutting size is fixed at a fixed position, which reduces practicality.
