[0034] like Figures 2 to 4 As shown, this utility model provides a packaging bag tongue-and-mouth separation mechanism, including: a tongue-and-mouth mounting frame assembly 1, on which two sets of tongue-and-mouth separation blades 2 are rotatably mounted; a tongue-and-mouth driving assembly 3, disposed on the tongue-and-mouth mounting frame assembly 1, the output end of which is connected to the tongue-and-mouth separation blades 2 to drive the tongue-and-mouth separation blades 2 to rotate; a lower tongue-and-mouth adsorption assembly 5, used to adsorb the lower layer of the double-layer tongue-and-mouth; and an upper tongue-and-mouth adsorption assembly 4, disposed on the tongue-and-mouth mounting frame assembly 1, used to adsorb the upper layer of the double-layer tongue-and-mouth.
[0035] This utility model provides a packaging bag tongue-and-mouth separation mechanism and a packaging machine. When the packaging bag is conveyed to the packaging bag tongue-and-mouth separation mechanism on the packaging bag conveying mechanism of the packaging machine, the upper tongue-and-mouth adsorption component 4 and the lower tongue-and-mouth adsorption component 5 respectively adsorb the upper and lower layers of the double-layer tongue-and-mouth. The tongue-and-mouth driving component 3 drives the tongue-and-mouth separation knife 2 to rotate, and the tongue-and-mouth separation knife 2 cuts and separates the tongue-and-mouth edge, realizing automated tongue-and-mouth edge cutting and separation.
[0036] like Figures 2 to 4 As shown, the tongue mounting bracket assembly 1 includes a first tongue connecting plate 11, which is connected to the packaging bag conveying mechanism of the packaging machine. The first tongue connecting plate 11 has a first tongue connecting groove 111, which connects to the packaging bag conveying mechanism and allows adjustment of the installation position of the entire packaging bag tongue separation mechanism.

[0037] like Figures 2 to 4 As shown, a tongue bearing 141 is provided at one end of the fourth tongue connecting plate 14, and a tongue connecting shaft 142 is provided on the tongue bearing 141. The top of the tongue connecting shaft 142 is connected to the tongue separating knife 2. The two tongue separating knives 2 shown are rotated clockwise and counterclockwise. When the two tongue separating knives 2 are rotating, they will first extend into the double tongue opening, and then cut and separate the edges of the tongue opening as they rotate.
[0038] like Figures 2 to 4 As shown, the tongue-and-mouth drive assembly 3 includes a tongue-and-mouth separation drive cylinder 31, which is connected to the lower part of the other end of the fourth tongue-and-mouth connecting plate 14. A tongue-and-mouth separation hinge ring 32 is provided at the output end of the tongue-and-mouth separation drive cylinder 31. A tongue-and-mouth linkage plate 33 is hinged to the tongue-and-mouth separation hinge ring 32, and the tongue-and-mouth linkage plate 33 is connected to the bottom of the tongue-and-mouth connecting shaft 142. The tongue-and-mouth separation drive cylinder 31 drives the tongue-and-mouth separation hinge ring 32 to move, which in turn causes the tongue-and-mouth linkage plate 33 to swing. The tongue-and-mouth linkage plate 33 then drives the tongue-and-mouth connecting shaft 142 to rotate, thereby causing the tongue-and-mouth separation blade 2 to rotate.
[0039] like Figures 2 to 4As shown, a fifth tongue-mouth connecting plate 15 is connected to the middle of the third tongue-mouth connecting plate 13. The position of the fifth tongue-mouth connecting plate 15 can be adjusted and moved relative to the third tongue-mouth connecting plate 13, and then fixed after adjustment and movement. The tongue-mouth adsorption assembly 4 includes a tongue-mouth adsorption driving cylinder 41. The fifth tongue-mouth connecting plate 15 is provided with the tongue-mouth adsorption driving cylinder 41.

Two sets of tongue-mouth suction cups 42 are provided. The tongue-mouth suction cups 42 are connected to the tongue-mouth connecting plate through the sixth tongue-mouth connecting groove 161. The position of the tongue-mouth suction cups 42 can be adjusted.
[0040] like Figures 2 to 4 As shown, the under-tongue adsorption assembly 5 includes an under-tongue adsorption plate 51, which has a plurality of under-tongue adsorption holes 511. The under-tongue adsorption plate 51 is installed on the packaging bag conveying mechanism, and the under-tongue suction holes can be connected to a vacuum adsorption fan or similar device to provide an adsorption force.
[0041] like Figures 2 to 4 As shown, a seventh tongue-and-mouth connecting plate 17 is also connected to the top of the fifth tongue-and-mouth connecting plate 15, and a tongue-and-mouth sensor 6 is provided on the seventh tongue-and-mouth connecting plate 17. The tongue-and-mouth sensor 6 can be a proximity switch, and the tongue-and-mouth sensor 6 is used to sense when the packaging bag is conveyed to the packaging bag tongue-and-mouth separation mechanism, at which point the entire mechanism starts.
[0042] This utility model embodiment provides a packaging bag tongue-and-mouth separation mechanism. The principle is as follows: the packaging bag conveying mechanism conveys the packaging bag to the area below the tongue-and-mouth sensor 6. After the tongue-and-mouth sensor 6 senses the packaging bag, the tongue-and-mouth suction hole 511 on the tongue-and-mouth suction plate 51 will adsorb the lower layer of the double-layer tongue-and-mouth. At the same time, the tongue-and-mouth suction cup 42 will adsorb the upper layer of the double-layer tongue-and-mouth. The tongue-and-mouth suction cup 42 moves upward to open the opening of the double-layer tongue-and-mouth. Then, the tongue-and-mouth separation driving cylinder 31 drives the tongue-and-mouth separation blade 2 to rotate, cutting and separating the edge of the tongue-and-mouth. After completing the entire action process, it resets and repeats the tongue-and-mouth cutting and separation process for the next packaging bag.
