[0025] The base frame 1 has a horizontal plate 11 and a vertical plate 12 perpendicular to the horizontal plate 11; the horizontal plate 11 is used to support the packaging bag, and the vertical plate 12 is used to provide installation and placement for various components.

[0026] The transverse cutting mechanism 2 includes a blade holder 21, a first driving member 22, a first blade holder 23, and a strip-shaped blade 24. The blade holder 21 is slidably disposed on the rear side of the vertical plate 12. The first driving member 22 is disposed on the rear side of the vertical plate 12 and located above the blade holder 21. The telescopic end of the first driving member 22 is connected to the blade holder 21. The first driving member 22 can drive the blade holder 21 to move vertically closer to or away from the transverse plate 11. The upper end of the first blade holder 23 is disposed on the blade holder 21. The strip-shaped blade 24 is detachably disposed on the lower end of the first blade holder 23. During operation, the first driving member 22 drives the blade holder 21 to move towards the transverse plate 11. The movement of the blade holder 21 drives the first blade holder 23 to move, thereby driving the strip-shaped blade 24 to move towards the transverse plate 11 to perform transverse cutting on the packaging bag on the transverse plate 11. It should be noted that the first driving member 22 can be a cylinder, an electric cylinder, or a hydraulic cylinder.

[0027] The longitudinal cutting mechanism 3 includes a fixed cutting blade assembly 31, a movable cutting blade assembly 32, and a moving assembly 33. The fixed cutting blade assembly 31 is located at the center of the front side of the vertical plate 12. There are two movable cutting blade assemblies 32 and two moving assemblies 33. Both moving assemblies 33 are located on the front side of the vertical plate 12 and are symmetrically arranged on both sides of the fixed cutting blade assembly 31. The two movable cutting blade assemblies 32 are respectively located on the movable ends of the two moving assemblies 33. The moving assemblies 33 can move the movable cutting blade assemblies 32 laterally closer to or away from the fixed cutting blade assembly 31. Before starting work, the distance between the two movable cutting blade assemblies 32 is determined according to the processing size of the packaging bag. The moving assemblies 33 drive the movable cutting blade assemblies 32 to a suitable position. During work, the fixed cutting blade assembly 31 and the movable cutting blade assembly 32 cooperate to longitudinally cut the packaging bag on the horizontal plate 11.

[0028] The first tool holder 23 has a mounting hole 231, and the strip-shaped blade 24 has a first through hole 241. A first bolt 242 passes through the first through hole 241, and a nut 243 is threaded through the mounting hole 231. Thus, the strip-shaped blade 24 adopts a detachable installation design, and different specifications of blades can be replaced according to processing needs during use, which has good applicability and further increases practicality.

[0029] The moving component 33 includes a slide block 331 slidably disposed on the front side of the vertical plate 12 and a second driving member 332 for driving the slide block 331 to move. The movable cutting blade assembly 32 is disposed on the slide block 331. In use, the slide block 331 moves under the drive of the second driving member 332, thereby driving the movable cutting blade assembly 32 to a suitable position. In this embodiment, the second driving member 332 includes a lead screw 3321, a screw sleeve 3322, a lead screw seat 3323, and a hand crank 3324. There are two lead screw seats 3323, which are spaced apart on the front side of the vertical plate 12. 321 is rotatably positioned between two lead screw seats 3323. A threaded sleeve 3322 is fitted onto the lead screw 3321 and connected to the slide block 331. One end of the lead screw 3321 passes through the lead screw seat 3323 and is connected to the hand crank handle 3324. In use, the lead screw 3321 is rotated by rotating the hand crank handle 3324. The rotation of the lead screw 3321 causes the threaded sleeve 3322 to move along the lead screw 3321. The movement of the threaded sleeve 3322 causes the slide block 331 to move. The movement of the slide block 331 causes the movable cutting blade assembly 32 to move. It should be noted that the second driving component 332 can also be a cylinder, a hydraulic cylinder, or an electric cylinder.

[0030] Both the fixed cutting blade assembly 31 and the movable cutting blade assembly 32 include a mounting plate 311, a third drive member 312, a second blade holder 313, a fourth drive member 314, a rotating shaft 315, and a rotary blade 316. The mounting plate 311 extends longitudinally. The third drive member 312 is mounted on the mounting plate 311. The second blade holder 313 is mounted on the movable end of the third drive member 312. The third drive member 312 can drive the second blade holder 313 to move vertically closer to or away from the transverse plate 11. The rotating shaft 315 is rotatably mounted on the lower end of the second blade holder 313. The rotary blade 316 is detachably mounted on the rotating shaft 315. The fourth drive member 314 is... On the second tool holder 313, the output end of the fourth drive member 314 is connected to the rotating shaft 315, and the fourth drive member 314 can drive the rotating shaft 315 to rotate. During operation, the third drive member 312 drives the second tool holder 313 to move towards the transverse plate 11, thereby driving the rotary blade 316 to move towards the transverse plate 11 to perform longitudinal cutting on the packaging bag on the transverse plate 11. During the cutting process, the fourth drive member 314 can drive the rotating shaft 315 to rotate, thereby driving the rotary blade 316 to rotate, achieving a better cutting effect. It should be noted that the third drive member 312 can be a cylinder, hydraulic cylinder or electric cylinder, and the fourth drive member 314 can be a motor.

[0031] The rotary blade 316 has a shaft hole 3161 through which the rotating shaft 315 passes. The side of the rotary blade 316 has a fixing sleeve 3162 that is concentrically arranged with the shaft hole 3161. The surface of the fixing sleeve 3162 has a second through hole 3163, and a second bolt 3164 passes through the second through hole 3163. The surface of the rotating shaft 315 has a threaded hole 3151, and the second bolt 3164 passes through the second through hole 3163 and is threadedly connected to the threaded hole 3151. In this way, the rotary blade 316 adopts a detachable installation design, and different specifications of blades can be replaced according to processing needs during use, which has good applicability and further increases practicality.

[0032] In order to make the second tool holder 313 move more stably, the second tool holder 313 is provided with a guide post 3131, and the mounting plate 311 is provided with a guide block 3111. The guide block 3111 has a guide hole 3112 for the guide post 3131 to pass through.
