[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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.

[0029] See also Figures 1 to 3 A lid opening device for a horizontal packaging machine comprises: a rotating body 1, whose rotating shaft is arranged horizontally; a vacuum mechanism 2, disposed on the outer periphery of the rotating body 1 and capable of applying vacuum to the packaging bag; and a lid opening mechanism 3, which can open or close the lid 22 of the vacuum mechanism 2 during the rotation of the rotating body 1. By arranging the rotating shaft horizontally, the number of vacuum chambers 21 along the length of the rotating shaft is increased, significantly improving production efficiency and enabling the lid 22 to be opened or closed automatically.

[0030] The cover opening mechanism 3 comprises: a second fixed disk 12, which is mounted on the rotating body 1 and does not rotate with the rotating body 1; a cam groove 121, provided on the second fixed disk 12; a swing shaft 33, rotatably mounted on the vacuum mechanism 2; a swing block 32, whose first end is fixedly connected to the end of the swing shaft 33; and a slider 34, mounted on the second end of the swing block 32 and slidably mounted within the cam groove 121. As the vacuum mechanism 2 rotates with the rotating body 1, the cam groove 121 drives the swing block 32 and the swing shaft 33 to rotate. Rotation of the swing shaft 33 drives the cover 22 to open or close the vacuum mechanism 2. During rotation of the rotating body 1, the second fixed disk 12 remains fixed and does not rotate. The slider 34 slides within the cam groove 121, thereby driving the swing block 32 and the swing shaft 33 to rotate. Rotation of the swing shaft 33 drives the cover 22 to open or close the vacuum mechanism 2, thereby automatically opening or closing the cover 22.

[0031] The cover 22 of the vacuum mechanism 2 is provided with an opening link 36 that can drive the cover 22 to open or close. A cover opening shaft 31 is fixed to the end of the opening link 36. The cover opening shaft 31 can be connected to the swing shaft 33 via a linkage rod 35. The swing shaft 33 is linked with the linkage rod 35 and the opening shaft 31 to automatically open or close the cover 22.

[0032] In the first embodiment, the vacuum mechanism 2 comprises a vacuum seat, connected to the rotating body 1 on both sides. A series of vacuum chambers are located within the vacuum seat, and a cover 22 covers the vacuum seat. This structure utilizes a single vacuum chamber, and the number of vacuum chambers determines the number of processes. The rectangular shape allows for the installation of many vacuum chambers, significantly increasing the number of vacuum chambers and improving production efficiency.

[0033] In the second embodiment, the vacuum mechanism 2 includes a mounting frame connected to the rotating body 1 on both sides; a series of vacuum chambers 21 are provided on the mounting frame. This structure differs from the first embodiment in that the number of vacuum chambers installed on the mounting frame can be adjusted to accommodate the desired number of processing operations. This structure offers the advantage of allowing the vacuum chambers to be installed and removed as needed.

[0034] A series of vacuum mechanisms 2 are evenly arranged in the axial direction of the rotating body 1. The length square can increase the number of vacuum chambers, greatly increase the number of vacuum chambers, and improve production efficiency.

[0035] A set of mounting seats is respectively provided on both sides of the vacuum mechanism, and both ends of the swing shaft are rotatably mounted on the mounting seats.

[0036] The linkage rod is arranged near the middle of the cover opening rotating shaft and the swing shaft.

[0037] A roller is rotatably provided on the slider, and the roller is rotatably installed in the cam groove.

[0038] After adopting the above structure, by placing the rotating shaft horizontally, the number of vacuum chambers can be increased in the length direction of the shaft, which greatly increases the number of vacuum chambers, improves production efficiency, and realizes automatic opening or closing of the cover.
