The advantage of this is that after the handle anti-scratch and wear plate is formed, the self-adhesive coating can be directly produced, and there is no need to perform additional processing on the self-adhesive coating, thereby reducing the number of processes and improving efficiency.

[0018] The self-adhesive coating on the anti-scratch sheet of the handle is formed by an upward folding gluing method, the main purpose of which is to make a longitudinal fold on the right side of the anti-scratch sheet of the handle so that the anti-scratch sheet of the handle can be folded in a longitudinal straight line when in use, thereby avoiding the problem of irregular and uneven folding edges on the right side of the anti-scratch sheet of the handle without longitudinal folding. When the user carries the bag, the user will feel uncomfortable due to the irregular and uneven folding edges when holding it. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The ear hole punching piece 281 includes an ear hole punching body 2811 , and the ear hole punching body 2811 is in a “[” shape, and a glue coating component opening 2812 is formed on the right side of the ear hole punching body 2811 .

[0027] The glue coating assembly 282 includes a cross frame 2821, and a plurality of sleeve rods 2822 are vertically movably sleeved on the cross frame 2821, and a compression spring 2823 is sleeved on the rod body of each sleeve rod 2822, and a glue coating plate group 2824 is transversely connected between the lower ends of each sleeve rod 2822, and a plurality of glue coating heads 2825 are sleeved at oblique intervals on the left side of the bottom surface of the glue coating plate group 2824.

[0028] The glue coating plate group 2824 is composed of a surface cover 28241 and a glue coating plate body 28242, and a glue cavity 28243 is opened on the left side of the top surface of the glue coating plate body 28242, and an inclined section 28244 is opened on the left side of the bottom surface of the glue coating plate body 28242, and the angle between the cross section of the inclined section 28244 and the horizontal plane is 25-30°, and a plurality of glue coating head embedding grooves 28245 are spaced apart on the cutting surface of the inclined section 28244, and a plurality of glue inlet holes 28246 are opened between the top surface of each glue coating head embedding groove 28245 and the glue cavity 28243, and a glue inlet port 28247 connected to the glue cavity 28243 is opened on the upper end of the surface cover 28241.

[0030] Working principle: The packaging bag is used in a manner that, during transportation, a plurality of packaging bags 1 can be stacked together. Since the surface layer 12 is made of a PE film material, the self-adhesive coating 17 adheres to the surface layer 12 and can be easily separated when stacked.

[0031] In addition, when in use, the beverage cup is placed in each cup sleeve opening 13 from top to bottom, and then the packaging bag 1 can be easily folded regularly according to the various folds pressed at intervals on the packaging bag 1. At this time, one side of the handle anti-scratch sheet 16 can be passed through the first ear hole 14 and attached to the surface layer 12 outside the first ear hole 14 with the self-adhesive coating 17. In this way, the folded packaging bag 1 will not unfold without external force. When carrying, the user passes the hand between the first ear hole 14 and the second ear hole 15 and holds the handle anti-scratch sheet 16. In this way, when lifting the packaging bag 1, there will be no scratching feeling on the upper side of the hole edge of the first ear hole 14 and the second ear hole 15, and the strength of the structure between the first ear hole 14 and the second ear hole 15 can be enhanced.

[0032] The production method of the punching device 2 is as follows: first, the cut piece of the packaging bag 1 is automatically caught and placed on the material discharge positioning edge 215 for accurate positioning and discharge, and then the telescopic device 221 on the punching group 22 is lowered, and the first punching knife 26, the first ear hole punching knife 27, and the second ear hole punching knife assembly 28 are synchronously driven to descend through the punching plate 222. When the lower end tips of the first punching knife 26, the first ear hole punching knife 27 and the ear hole punching knife member 281 press against the top surface of the packaging bag 1, because the bottom surface of the roller pressing member 29 is designed to be 1 cm higher than the bottom surface of the ear hole punching knife member 281, at this time, the bottom end of the roller pressing member 29 and the top surface of the pressing rod 2523 are also in a state of being in contact with each other (refer to the attached Fig. 9), then the first punching knife 26, the first ear hole punching knife 27 and the ear hole punching knife member 281 continue to descend and cooperate with the first bottom knife 23, the first ear hole bottom knife 24 and the second ear knife incision 2512 to punch the packaging bag 1 to obtain each cup sleeve 13, the first ear hole 14, the second ear hole 15 and the handle anti-scratch wear sheet 16. In this process, the synchronous roller pressing member 29 will continue to descend to press the pressing rod 2523, and through the first connecting rod 2521 and the second connecting rod 2522, the flap body 2524 The handle anti-scratch sheet 16 is flipped 27° to the upper right in the flip groove 2513, so that each glue head 2825 on the oblique section 28244 formed by the 27° acute angle between the top surface of the handle anti-scratch sheet 16 and the bottom surface of the glue coating plate group 2824 is pressed and glued to obtain each self-adhesive coating 17. In addition, due to the positioning and folding of the handle anti-scratch sheet 16, a regular fold is formed on the right side of the handle anti-scratch sheet 16, which is convenient for the folding and interlacing use of the handle anti-scratch sheet 16 when the packaging bag 1 is used.

[0033] In addition, the slag produced when punching the cup sleeve openings 13 and the first ear holes 14 will automatically be discharged into the slag collecting box 210 in the slag discharge cavity 216 and collected.

[0034] In addition, when the flip mechanism 252 drives the handle anti-scratch plate 16 to flip up to the right and press against the glue-coating plate group 2824 for glue coating, due to the action of the compression spring 2823 and the sleeve rod 2822, the glue-coating plate group 2824 has an upward buffering effect, so there will be no hard pressure phenomenon, thereby ensuring that the first connecting rod 2521, the second connecting rod 2522, and the pressure rod 2523 on the flip mechanism 252 will not be deformed by the hard force.

[0035] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.
