[0038] The adjustable transverse sealing assembly 32 includes a second upright frame 321, a second bracket 322, a second horizontal plate 323, a second cylinder 324, a C-shaped frame 325, a threaded rod 326, a fixed rod 327, a movable plate 328, a second sealing blade 329, and a handle 330. The second upright frame 321 is located to the left of the first upright frame 311. The second bracket 322 is symmetrically fixedly connected to the top of the second upright frame 321.

The handle 330 drives the threaded rod 326 to move the moving plates 328 on both sides synchronously towards each other or synchronously away from each other in the front-to-back direction, thereby adjusting the distance between the two sealing heads 329.

[0040] In this invention, cylinder 314 drives connecting plate 315 to move sealing head 316 downward, achieving longitudinal sealing of the double-layer film. Cylinder 324 drives C-frame 325 to move moving plate 328 and sealing head 329 downward via threaded rod 326, achieving transverse sealing of the double-layer film, thus forming the packaging bag. Handle 330 drives threaded rod 326 to move moving plate 328 on the front and rear sides synchronously, thereby adjusting the distance between sealing head 329 on the front and rear sides, thus enabling the production of different packaging bags using films of different widths.

[0041] In some embodiments, the parking mechanism 4 includes a driving component 41 and a fixing component 42. The driving component 41, which drives the fixing component 42 to move up and down, is located on the left side of the support frame 321. The fixing component 42, which is used to fix the packaging bag, is located on the top of the driving component 41.

[0042] The drive assembly 41 includes a third upright 411, a third bracket 412, a drive motor 413, a first cam 414, and a second cam 415. The third upright 411 is located on the left side of the first upright 411. The third bracket 412 is fixedly connected to the top of the third upright 411. The drive motor 413 is fixedly connected to the top of the third bracket 412. The first cam 414 is fixedly connected to the output end of the drive motor 413. The second cam 415 is rotatably connected to the front end of the first cam 414. The first cam 414 and the second cam 415 have the same structure and radius. Both the front end surfaces of the first cam 414 and the second cam 415 are provided with through grooves. The rear end of the bolt 416 passes through the grooves on the first cam 414 and the second cam 415 in sequence and is slidably connected. The rear end of the bolt 416 is threaded with a nut.

[0043] The fixing component 42 includes a drive rod 421, a pressure block 422, a slide rod 423, a spring 424, and a rotating wheel 425. The bottom of the drive rod 421 passes through the top of the bracket 3 412 and is slidably connected. The top of the drive rod is rotatably connected to the rotating wheel 425. The circumferential sidewalls of the rotating wheel 425 are in contact with the sidewalls of the cam 1 414 and the cam 2 415. The bottom of the drive rod 421 is fixedly connected to the pressure block 422. The top of the pressure block 422 is fixedly connected to multiple slide rods 423. The tops of the multiple slide rods 423 slide through and extend to the outer side of the top of the bracket 3 412. A spring 424 is sleeved on the outer side of the top of each slide rod 423. The top of the spring 424 is fixedly connected to the top surface of the slide rod 423, and the bottom of the spring 424 is fixedly connected to the top of the bracket 3 412. Since the circumferential sidewall of the rotating wheel 425 simultaneously contacts and abuts against the sidewalls of cam 1 414 and cam 2 415, the time for the pressure block 422 to press down on the packaging bag after moving downward is adjusted by changing the length of the arc surface of the distal end of cam 1 414 and cam 2 415 combined.

[0044] In this utility model, tightening bolt 416, with the nut, fixes cam 1 414 and cam 2 415. At this time, the output of drive motor 413 drives cam 1 414 to rotate, and cam 1 414 drives cam 2 415 to rotate via bolt 416. When the distal ends of the sidewalls of cam 1 414 and cam 2 415 rotate to their lower sides and abut against the circumferential sidewall of rotating wheel 425, cam 1 414 and cam 2 415 drive rotating wheel 425, which in turn drives pressure block 422 to move downwards to fix the packaging bag via drive rod 421. When the distal ends of wheel 414 and cam 415 abut against the circumferential sidewall of the rotating wheel 425, the packaging bag remains fixed, and the spring 424 extends. When the proximal ends of cam 414 and cam 415 rotate to their lower sides and abut against the circumferential sidewall of the rotating wheel 425, the spring 424 resets, driving the drive rod 421 upward through the pressure block 422. The drive rod 421 then drives the rotating wheel 425 upward, ensuring that the circumferential sidewall of the rotating wheel 425 remains in contact with the sidewalls of cam 414 and cam 415, thus releasing the fixation of the packaging bag. By loosening bolt 416, the fixation between cam 414 and cam 415 is released. At this time, rotating cam 415 adjusts the angle between cam 414 and cam 415, thereby adjusting the time when the distal ends of cam 414 and cam 415 abut against the top side of the rotating wheel 425.

[0045] In this invention, the output end of the drive motor 413 drives the first cam 414 and the second cam 415 to rotate, thereby fixing the packaging bag; the bolt 416 and the nut are used to adjust the time when the distal end of the first cam 414 and the second cam 415 abuts against the top side of the rotating wheel 425, thereby adjusting the time when the packaging bag is fixed.

[0046] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
