[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 work are within the scope of protection of the present invention. The present invention is further described in conjunction with the drawings and embodiments:

[0023] Refer to the attached Figure 1 As shown, a lifting structure of a capping machine includes a mounting plate 1, a guide rod 2, a sliding sleeve 3, a lifting plate 4 and a double-stroke cylinder 5; wherein, the mounting plate 1 plays a mounting and fixing role, and a guide rod 2 is vertically arranged on it. Considering the stability and simplicity of the lifting structure, in this embodiment, there are two guide rods 2, and each of the two guide rods 2 is slidably fitted with a sliding sleeve 3. A lifting plate 4 for mounting a vacuum mechanism and a capping mechanism is commonly mounted on the two sliding sleeves 3. The lifting plate 4 is horizontally arranged and connected to the telescopic end of the double-stroke cylinder 5 vertically arranged on the mounting plate 1, so that the double-stroke cylinder 5 can operate and cause the lifting plate 4 to perform two linear movements in the same direction.

[0024] During the specific implementation of this solution, the vacuum mechanism and the capping mechanism are arranged on the lifting plate 4. Under the first operation of the two-stroke cylinder 5, the lifting plate 4 moves along the guide rod 2 to complete the first stage of linear motion, so that the vacuum mechanism moves down a distance to seal the glass bottle, and then the vacuum operation is completed. Subsequently, under the second operation of the two-stroke cylinder 5, the lifting plate 4 moves along the guide rod 2 again to complete the second stage of linear motion, so that the capping mechanism moves down a distance to contact the glass bottle cap, and then the capping operation is completed.

[0025] In order to avoid the collision or damage caused by excessive inertia during the operation of the double-stroke cylinder 5 in the above scheme, Figure 1As shown, each of the two guide rods 1 and 2 is provided with a set of buffer components 6, so that when the double-stroke cylinder 5 drives the lifting plate 4 to perform the second linear motion, the buffer components 6 contact the sliding sleeve 1 and 3, thereby achieving the purpose of buffering.

[0026] Among them, the buffer assembly 6 includes an upper hole seat 61, a lower hole seat 62 and a spring 63; the upper hole seat 61 is fixedly set on the top of the guide rod 2, and the lower hole seat 62 is provided below the upper hole seat 61. The lower hole seat 62 is slidably set on the outside of the guide rod 2, and a spring 63 is provided between the lower hole seat 62 and the upper hole seat 61. The spring 63 is sleeved on the outside of the guide rod 2 so that when the lower hole seat 62 is under pressure, the spring 63 can play a buffering role.

[0027] In addition, when targeting glass jars of different heights and sizes, the running distance of the two-stroke cylinder 5 needs to be changed. Therefore, it is necessary to replace the two-stroke cylinder 5 with a different stroke or change the installation position of the two-stroke cylinder 5, so that the running distance of the vacuum mechanism and the screw cap mechanism installed on the lifting plate 4 can be adjusted to adapt to the use of glass jars of different heights and sizes. In order to avoid the time-consuming and labor-intensive problems caused by repeated disassembly and adjustment, refer to the attached Figure 2 -Attached Figure 4 As shown, a height adjustment assembly 7 is provided at the bottom of the mounting plate 1 to change the initial height of the lifting plate 4, thereby adapting to the use of glass jars of different heights and sizes;

[0028] Refer to the attached Figure 2 As shown, the height adjustment assembly 7 includes a guide portion 71 and a drive portion 72; the mounting plate 1 is slidably disposed on the guide portion 71, and the mounting plate 1 is connected to the drive portion 72, so that by operating the drive portion 72, the mounting plate 1 is adjusted in the vertical direction along the guide portion 71;

[0029] For the above scheme, refer to the attached Figure 2 and attached Figure 3 As shown, the guide portion 71 includes a fixed plate 711, a second guide rod 712, and a second sliding sleeve 713.

The lifting end of the hand-cranked screw lift 722 is connected to the bottom of the mounting plate 1, and the operating end of the hand-cranked screw lift 722 extends outside the space for easy operation by the user;

[0032] Refer to the attached Figure 4 As shown, in the second embodiment, the driving part 72 includes a mounting seat 723, a guide rod 3 724, a long screw 725, a crank 726, a connecting seat 727 and a connecting rod 728; the mounting seat 723 is arranged on the fixed plate 711, and the guide rod 3 724 and the long screw 725 are horizontally slidably provided on the mounting seat 723, and the outer end of the long screw 725 extends to the outside of the space and is connected to the crank 726, and the inner end of the long screw 725 and the inner end of the guide rod 3 724 are commonly connected to the connecting seat 727, and the connecting seat 727 is hinged to one end of the connecting rod 728, and the other end of the connecting rod 728 is hinged to the bottom of the mounting plate 1, so that the connecting seat 727 can be moved forward or backward by operating the crank 726, and finally the connecting rod 728 lifts the mounting plate 1.
