[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0019] See also Figures 1 to 3, the utility model provides a technical solution:

[0020] A vacuum packaging machine suction nozzle lifting device comprises a mounting seat 1, a lifting groove is provided on one side of the mounting seat 1, a slide plate 2 is slidably installed on the outer side of the lifting groove, a lifting component for driving the slide plate 2 to move is installed inside, and limit plates 3 are provided on both sides of the lifting groove, the two sides of the slide plate 2 are respectively slidably connected to the limit plates 3, limit seats 4 are symmetrically provided above the slide plate 2, a mounting hole is provided inside the limit seat 4, an arc hole corresponding to the position of the mounting hole is provided on the mounting seat 1, an exhaust pipe 5 is fixedly inserted inside the mounting hole, and the exhaust pipe 5 passes through the outside of the arc hole and is installed with the exhaust nozzle 6.

[0021] When in use, the slide plate 2 is driven to rise through the lifting component, and the slide plate 2 drives the exhaust pipe 5 and the exhaust nozzle 6 to rise, so as to achieve the purpose of lifting and lowering adjustment. During the rising process of the slide plate 2, the two ends of the slide plate 2 are limited by setting the limit plate 3, so that the slide plate 2 can stably make horizontal movements in the vertical direction when rising, thereby improving the stability during lifting and lowering adjustment.

[0022] The lifting component includes a threaded rod 7 installed inside the lifting groove and a slider 8 connected to the threaded rod 7 by spiral transmission. The slide plate 2 is installed on the outside of the slider 8. A motor 9 for driving the threaded rod 7 to rotate is installed inside the mounting seat 1. The motor 9 drives the threaded rod 7 to rotate forward and reverse, so that the slider 8 makes reciprocating motion on the threaded rod 7, replacing the traditional hydraulic cylinder, enhancing applicability and reducing production costs.

[0023] A limiting groove is provided on one side of the limiting plate 3 close to the lifting groove, and a limiting block 10 is slidingly connected inside the limiting groove. Both ends of the slide plate 2 are respectively connected to the limiting blocks 10. When the slider 8 drives the slide plate 2 to move, the slide plate 2 will simultaneously drive the limiting blocks 10 at both ends to move inside the limiting groove, further improving stability.
