Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1

[0024] like Figure 1-4 As shown, an anti-sticking device for a packaging machine in the figure includes a connecting frame 1 and a buffer mechanism arranged on the top of the connecting frame 1, and the buffer mechanism includes a working component and a buffer component;

[0025] The working assembly includes a cylinder 2, the cylinder 2 is arranged outside the connection frame 1, the outer wall of the cylinder 2 is fixedly connected to the support frame 3, one end of the cylinder 2 is fixedly connected to the sealing plate 4, the inner wall of the support frame 3 is fixedly connected to the limiting column 5, the inner wall of the sealing plate 4 is slidably connected to the limiting column 5, and the top of the sealing plate 4 is fixedly connected to the first fixing block 6;

[0026] The buffer assembly includes a base column 7, one side of the first fixed block 6 is fixedly connected to the base column 7, one side of the base column 7 is fixedly connected to a hollow column 8, the inner wall of the hollow column 8 is slidably connected to a sliding column 9, the outer wall of the sliding column 9 is provided with a first spring 10, one end of the sliding column 9 is fixedly connected to an extrusion plate 11, one side of the extrusion plate 11 is rotatably connected to a connecting rod 12, one end of the connecting rod 12 is rotatably connected to a sliding ring 13, the inner wall of the sliding ring 13 is slidably connected to a connecting column 14, and the outer wall of the connecting column 14 is provided with a second spring 15.

[0027] Among them, Figure 3 As shown, the sealing plate 4 is provided with a sliding groove that matches the limiting column 5. The sealing plate 4 forms a sliding structure with the limiting column 5 through the cylinder 2, which is beneficial to ensure the stability of the sealing plate 4 during movement and prevent incomplete sealing.

[0028] Among them, Figure 3 As shown, the hollow column 8 is provided with a sliding groove that matches the sliding column 9. The sliding column 9 forms a buffer structure with the hollow column 8 through the first spring 10 and the extrusion plate 11, which is beneficial for the sliding column 9 to pop out from the groove of the hollow column 8 when the sealing plate 4 contracts, so that the extrusion plate 11 squeezes the sealing bag to make it detach from one end of the sealing plate 4.

[0029] Among them, Figure 2 As shown, the sliding ring 13 is provided with a sliding groove that matches the connecting column 14. The sliding ring 13 and the connecting column 14 form a sliding structure through the connecting rod 12, which is conducive to the contraction of the extrusion plate 11 to achieve the purpose of buffering.

[0030] Example 2

[0031] like Figure 1 , Figure 2 and Figure 4 As shown, this embodiment further illustrates Example 1, a grip rod 16 is provided on the outside of the connecting frame 1, the bottom end of the grip rod 16 is rotatably connected to a rotating disk 17, the bottom end of the rotating disk 17 is fixedly connected to a threaded column 18, the outer wall of the threaded column 18 is rotatably connected to a first positioning block 19, the outer wall of the threaded column 18 is spirally connected to a first fixing column 20, the outer wall of the connecting frame 1 is fixedly connected to the first fixing column 20, the outer wall of the supporting frame 3 is fixedly connected to the first positioning block 19, the outer wall of the supporting frame 3 is fixedly connected to the second fixing block 21, the bottom of the second fixing block 21 is fixedly connected to a sliding bar 22, and the outer wall of the connecting frame 1 is fixedly connected to a second fixing column 23.

[0032] Among them, Figure 4As shown, the first fixed column 20 is provided with a threaded groove that matches the threaded column 18.

[0033] Among them, Figure 1 As shown, the second fixed column 23 is provided with a sliding groove that matches the sliding bar 22. The sliding bar 22 forms a sliding structure with the second fixed column 23 through the second fixed block 21, which is conducive to ensuring the stability of the support frame 3 when it is raised or lowered.

[0034] When in use: first, the cylinder 2 drives the sealing plate 4 to slide on the outer wall of the limiting column 5, so that the sealing plate 4 heats and seals the sealing bag. At the same time, the extrusion plates 11 will contact each other, so that the sliding column 9 will shrink into the groove of the hollow column 8, relying on the first spring 10 to play the role of elastic support, and the connecting rod 12 pushes the sliding ring 13 to slide on the outer wall of the connecting column 14, relying on the second spring 15 to play the role of elastic support. When the sealing plate 4 falls off the sealing bag, the extrusion plate 11 will be released by elastic force to clamp the upper end of the sealing bag to prevent the sealing bag from sticking to the heating end of the sealing plate 4, thereby achieving the effect of falling off;

[0035] Finally, the staff holds the handle 16 to make the rotating disk 17 drive the threaded column 18 to rotate, so that the threaded column 18 can move spirally in the groove of the first fixed column 20, so as to adjust the position of the first positioning block 19 and the support frame 3, and perform sealing processing on different parts according to the length of the sealed bag. At the same time, when the support frame 3 is raised or lowered, the second fixed block 21 drives the sliding bar 22 to slide in the groove of the second fixed column 23, so as to ensure the stability of the lifting and lowering of the support frame 3 and prevent one side from tilting.
