[0024] As Figure 1 , Figure 2 , Figure 3 , Figure 4 A self-adapting container clamping device is shown in the drawings, which comprises a pair of clamping pieces 1 hingedly connected to the base 2 respectively, each clamping piece 1 comprising a clamping side plate body 11 and a driving side plate body 12, the clamping side plate body 11 and the driving side plate body 12 of each clamping piece 1 being located on the two sides of the hinged position with the base 2 respectively, the inner side of the clamping side plate body 11 of each clamping piece 1 being provided with a clamping part 111 for clamping the mouth of a container, and the outer ends of the clamping side plate bodies 11 of the two clamping pieces 1 forming an aperture 10 for the container to enter and exit.

[0025] The hinged connection structure of each clamping piece 1 and the base 2 in the embodiment comprises a cylindrical nut 9, the cylindrical body 901 of the cylindrical nut 9 being provided through the clamping piece 1, the mounting sleeve 91 and fixed to the base 2, a bearing being further provided between the cylindrical body 901 of the cylindrical nut 9 and the clamping piece 1, and a wear-resistant washer 92 being provided between the cap body of the cylindrical nut 9 and the clamping piece 1. In the embodiment, the lower end of the cylindrical body of the cylindrical nut 9 protrudes out of the base 2, and the protruding cylindrical body 901 is used to be fixed to the rotary disc 100 on which the container clamping device is installed, as shown in Figure 7 The container clamping device is installed on the rotary disc 100.

[0026] A first elastic component is provided between the pair of clamping pieces 1, which makes the clamping parts 111 of the pair of clamping pieces 1 always have a tendency to approach each other to clamp the container. In the embodiment, the first elastic component provided between the pair of clamping pieces 1 is a first compression spring 3, and the first compression spring 3 is provided between the driving side plate bodies 12. The outer end of each driving side plate body 12 is fixedly connected to a spring seat plate 4, two spring mounting seats are provided on each spring seat plate 4, and the two spring mounting seats on each spring seat plate 4 are located above the driving side plate body 12. The two spring mounting seats on each spring seat plate 4 are spaced apart upward and downward. In the embodiment, the two spring mounting seats on each spring seat plate 4 are a first spring mounting seat 41 and a second spring mounting seat 42 from top to bottom. The spring mounting seats on the two spring seat plates 4 correspond to each other, the spacing between each group of spring mounting seats is different, that is, the two groups of spring mounting seats are used to install compression springs with different natural lengths or the compression amount of the springs between the two groups of spring mounting seats is different. In the embodiment, the first compression spring 3 is installed on a pair of first spring mounting seats 41.

[0027] The spring mounting seat in the embodiment is located above the drive side plate body 12, which makes the first compression spring 3 located above the clamping piece 1. Such structure can effectively reduce the length of the drive side plate body 12, thereby greatly reducing the volume and weight of the whole container clamping device, and effectively reducing the installation contact area of the container clamping device on the whole rotary disc 100. This not only can save equipment cost, but also can effectively reduce the sanitary dead angle between the container clamping device and the rotary disc 100, thereby improving the cleanliness of the whole rotary equipment. In addition, the spring mounting seat is arranged above the drive side plate body 12, so that there is space to arrange multiple spring mounting seats, thereby providing installation positions of multiple compression springs with different clamping forces or different natural lengths, so as to better adapt to the needs of clamping different containers. In the embodiment, only two groups of spring mounting seats are taken as an example for description.

[0028] A limiting column 7 is fixedly arranged on the base 2 outside each drive side plate body 12, and each limiting column 7 is located below the spring seat plate 4 on the corresponding side. The limiting column 7 plays a limiting role in the outward opening of the drive side plate body 12. The drive side plate body 12 opens outward until it is blocked by the limiting column 7. At this time, the clamping portions 111 on a pair of clamping side plate bodies 11 are just close to each other to the minimum distance position, which is also the clamping position of the smallest diameter container that can be clamped, as shown in Figure 6 .

[0029] A sliding block 8 is movably arranged on the base 2. The sliding block 8 includes a sliding block body 81, and a stop block 82 is arranged at the front end of the sliding block body 81. The stop block 82 is provided with a leaning stop portion. Specifically, a sliding groove 22 is formed in the base 2, and the sliding block body 81 is arranged in the sliding groove 22. The sliding block body 81 moves forward and backward under the guidance of the sliding groove 22, and moves forward until it is blocked by the front end face 221 of the sliding groove 22. The front end face 221 of the sliding groove 22 limits the displacement of the sliding block body 81 moving forward.

[0030] In the embodiment, the front end of the wear-resistant washer 92 is provided with a washer limiting protrusion 921, and the sliding block body 81 moves backward until the stop block 82 is blocked by the washer limiting protrusion 921. The arrangement of the washer limiting protrusion 921 limits the displacement of the sliding block body 81 moving backward, as shown in Figure 5 , which is also the clamping position of the largest diameter container that can be clamped.

[0031] In the embodiment, the structure of the leaning stop portion includes two inwardly recessed arc-shaped leaning stop surfaces 821 arranged at the upper and lower of the front end of the stop block 82, and the two leaning stop surfaces 821 are respectively used for leaning on the outer walls on the upper and lower sides of the support ring of the container mouth. The inwardly recessed arc-shaped leaning stop surfaces 821 can improve the stability of the container transfer and clamping.

[0032] A second elastic component is arranged between the slider body 81 and the base 2, and under the elastic force of the second elastic component, the abutting portion of the stop block 82 always has a tendency to move towards the clamping portion 111 of the pair of clamping pieces 1. In this embodiment, the second elastic component is a second compression spring 5, and the two ends of the second compression spring 5 are respectively pressed on the slider body 81 and the mounting stop block 6, and the mounting stop block 6 is adjustably fixedly connected with the base 2.

[0033] Specifically, the adjustably fixed connection structure between the mounting stop block 6 and the base 2 includes that two long strip-shaped connecting holes 21 are formed on the base 2, and the two ends of the mounting stop block 6 are respectively locked in the two long strip-shaped connecting holes 21 by bolts. The long strip-shaped connecting holes 21 provide a position adjustment allowance for the mounting stop block 6. The position-adjustable fixed connection structure between the mounting stop block 6 and the base 2 aims to adjust the mounting position of the second compression spring 5 by adjusting the mounting position of the mounting stop block 6, so as to overcome the installation error, and at the same time, the mounting stop block 6 can also be adjusted to adapt to the installation of the second compression spring 5 with different initial lengths, so as to better meet the clamping of containers with different diameters.

[0034] When the container mouth portion is pressed through the gap 10 to enter between the pair of clamping side plate bodies 11, the elastic force of the first compression spring 3 ensures that the pair of clamping portions 111 can elastically press the container mouth portion on the abutting surface 821, so that the container is clamped.

[0035] The above-mentioned self-adaptive container clamping device has the following advantages: 1. The structure that a first elastic component is arranged between the pair of clamping pieces 1, and a second elastic component is arranged between the slider body 81 and the base 2, so that the pair of clamping portions 111 can be opened to a suitable clamping position according to the diameter of different containers, and at the same time, the slider body 81 can move forward or backward to a suitable clamping position according to the diameter of different containers, so as to realize self-adaptive clamping of various containers with different diameters, greatly improve the compatibility of the clamping device, and effectively avoid frequent replacement of the clamping device, thereby effectively saving the production cost of liquid filling. 2. The spring mounting seat for mounting the spring between the pair of clamping pieces 1 is arranged above the drive side plate body 12, which makes the spring between the pair of clamping pieces 1 be mounted above the clamping piece 1, which can effectively reduce the length of the plate body of the drive side plate body 12, thereby greatly reducing the volume and weight of the entire container clamping device, and effectively reducing the installation contact area of the container clamping device on the entire rotary disc 100, thereby not only saving equipment cost, but also effectively reducing the sanitary dead angle between the container clamping device and the rotary disc 100, thereby improving the cleanliness of the entire rotary equipment.
