When in use, the output shaft of the first motor 110 drives the driving bevel gear 121 to rotate synchronously through the key structure, drives the driven bevel gear 122 to rotate through the driving bevel gear 121, and drives the longitudinal seal driving shaft 132 to rotate synchronously through the key structure. Of course, the first transmission mechanism 120 can also adopt other forms of gear sets or worm gear mechanisms, etc.

[0044] In this embodiment, if Figures 7 to 9 As shown, the transverse sealing and cutting mechanism 240 includes a transverse sealing fixing frame 241, a transverse sealing left mold 242, a transverse sealing right mold 243, a left sealing cylinder 244, two right sealing cylinders 245, a cutting knife 246 and a cutting knife cylinder 247.

[0045] In this embodiment, if Figures 7 to 9As shown, in order to make the transverse sealing and pulling film more stable, the transverse sealing and edge sealing clamping and pulling mechanism 230 may also include a mechanical clamping mechanism 270, and the mechanical clamping mechanism 270 is fixedly mounted on the transverse sealing and cutting mechanism 240. The mechanical clamping mechanism 270 includes a finger cylinder 271, a left clamp 272 and a right clamp 273. The cylinder body of the finger cylinder 271 is fixedly mounted in the middle of the front side of the transverse sealing and cutting mechanism 240 (specifically, it can be a transverse sealing fixed frame 241), and the left clamp 272 and the right clamp 273 are respectively fixedly mounted on the left and right fingers of the finger cylinder 271. Among them, the mechanical clamping mechanism 270 is preferably, but not limited to, located above the transverse sealing left mold 242 and the transverse sealing right mold 243. When in use, when the transverse sealing edge clamping and pulling mechanism 230 moves downward, the packaging film is clamped by the mechanical clamping mechanism 270, and the packaging film is simultaneously transversely sealed and cut during the process of pulling the film downward, thereby solving the problem of the original plywood packaging machine's transverse sealing and film pulling and transverse sealing and cutting actions being separated, thereby simplifying the machine's operating steps and improving the machine's operating efficiency, enabling it to adapt to high-speed operating environments.

[0046] In this embodiment, if Figures 7 to 9 As shown, the transverse sealing lifting guide mechanism 260 includes two left and right parallel longitudinal slide rails 261 and two sliders 262 slidably matched with the corresponding longitudinal slide rails 261.

When in use, the second motor 210 rotates to drive the swing arm 221 to swing, and the swing arm 221 lifts the entire transverse sealing edge clamping and pulling mechanism 230 upwards through the connecting rod 222, and then the left sealing cylinder 244 and the right sealing cylinder 245 act to drive the transverse sealing left mold 242 and the transverse sealing right mold 243 to seal through the left mold fixing plate 250 and the right mold fixing plate 251 respectively. During the sealing process, the cutter cylinder 247 drives the cutting knife 246 to cut the bag, and at the same time, the second motor 210 reverses, driving the swing arm 221 to move in the opposite direction, and the swing arm 221 pulls the entire transverse sealing edge clamping and pulling mechanism 230 downward through the connecting rod 222, playing the role of pulling the film synchronously with the longitudinal sealing. When the second motor 210 is pulled to the set angle, the left sealing cylinder 244 and the right sealing cylinder 245 move in the opposite direction, separating the transverse sealing left mold 242 from the transverse sealing right mold 243 again, and repeating this process, the entire transverse sealing edge clamping and pulling mechanism 230 continuously reciprocates up and down. Of course, the second transmission mechanism 220 can also adopt a cam reciprocating transmission mechanism, etc.

[0050] The second transmission mechanism 220 is driven by the second motor 210, and the transverse edge sealing clamping and pulling mechanism 230 is driven by the second transmission mechanism 220 to move to the highest point as the origin;

[0051] The first transmission mechanism 120 is driven by the first motor 110, and the two heated longitudinal sealing edge film-drawing wheels 137 in the longitudinal sealing edge film-drawing mechanism 130 are driven to rotate by the first transmission mechanism 120, so that the two heated longitudinal sealing edge film-drawing wheels 137 longitudinally seal the packaging film while longitudinally drawing the film;

[0052] While the film is being pulled longitudinally, the second transmission mechanism 220 is driven by the second motor 210, and the transverse sealing edge clamping and pulling mechanism 230 is driven by the second transmission mechanism 220 to move downward by half a bag length to the lowest point at the same speed as the longitudinal film pulling, and then move back upward by half a bag length to the highest point, so that when the longitudinal sealing film pulling device 100 outputs one bag length, the transverse sealing clamping and pulling device 200 has returned to the original point, and the transverse sealing edge clamping and pulling mechanism 230 (specifically the transverse sealing and cutting mechanism 240) simultaneously seals and cuts the packaging film transversely during the downward movement to separate the upper and lower bags.
