[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1-Figure 3 As shown, a horizontal and vertical sealing linkage structure of a packaging machine includes a connecting rod 4 connected to the horizontal sealing device 2 at one end through a joint bearing 1, a connecting bracket 7 connected to the other end of the connecting rod 4 through a joint bearing 2, a slider 8 vertically fixed on the side of the vertical sealing device 3, a spring 6 fixedly connected to the top of the connecting bracket 5 at one end, and the other end of the spring 6 fixedly connected to the bottom end of the connecting bracket 7. The slider 8 is slidably set on a guide rail 9, and the guide rail 9 is fixed on the connecting frame 5. The horizontal sealing device 2 and the vertical sealing device 3 are arranged on the main mounting frame 1.

[0024] The connecting bracket 7 is arranged close to the slider 8 and is fixedly connected to the side of the vertical sealing device 3 .

[0025] The guide rail 9 is vertically fixed on the side of the connecting frame 5 .

[0026] The connecting frame 5 is vertically fixedly arranged on the upper end of the main mounting frame 1 .

[0027] The transverse sealing device 2 is horizontally slidably arranged on the main mounting frame 1 .

[0028] The vertical sealing device 3 is slidably connected to the main mounting frame 1 via a connecting frame 5 .

[0029] The connecting rod 4 is an adjustable connecting rod, and its length is adjustable.

[0030] The specific working process of this utility model:

[0031] A driving mechanism 1 is installed on the side of the main mounting frame 1, and the horizontal sealing device 2 is slidably connected to the main mounting frame 1. The driving mechanism 1 drives the horizontal sealing device 2 to slide up and down; when the driving mechanism 1 drives the horizontal sealing device 2 to slide upward, the horizontal sealing device 2 drives the connecting rod 4 to move upward, and the connecting rod 4 drives the connecting bracket 7 to move upward, and the connecting bracket 7 is fixed on the vertical sealing device 3. Therefore, when the connecting rod 4 drives the connecting bracket 7 to move upward, the vertical sealing device 3 will move upward along the guide rail 9.

[0032] The spring 6 is in a stretched state before the vertical sealing device 3 slides upward. When the vertical sealing device 3 slides upward, the spring 6 applies an upward pulling force to the vertical sealing device 3. After the vertical sealing device 3 slides to the critical point where the spring 6 returns to its original position, the spring 6 is compressed. At this time, the spring 6 applies a downward force to the vertical sealing device 3.

[0033] When the driving mechanism 1 drives the horizontal sealing device 2 to slide downward, the horizontal sealing device 2 drives the connecting rod 4 to move downward, the connecting rod 4 drives the connecting bracket 7 to move downward, and at the same time drives the vertical sealing device 3 to move downward along the guide rail 9.

[0034] The spring 6 is in a compressed state before the vertical sealing device 3 slides downward. When the vertical sealing device 3 slides downward, the spring 6 applies a downward force to the vertical sealing device 3. After the vertical sealing device 3 slides to the critical point where the spring 6 returns to its original position, the spring 6 is stretched. At this time, the spring 6 applies an upward force to the vertical sealing device 3.

[0035] When the horizontal sealing device 2 drives the vertical sealing device 3 to slide up and down along the guide rail 9 through the connecting rod 4, the spring 6 plays a role of buffering and reducing the workload in the above manner.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0037] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
