[0022] The present invention will be further described in detail below with reference to the accompanying drawings and preferred embodiments.

[0023] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 As shown, a translational container clamp comprises a pair of clips 1, each clip comprising a clamping side plate 11. Each clip 1 has a clamping portion disposed on the inner side of the clamping side plate 11 for clamping the container mouth. Each clip 1 also comprises a clip seat 12, with each clamping side plate 11 protruding outward from the corresponding clip seat 12. Each clip seat 12 is provided with a straight guide slot 13, each of which is provided with a guide block 2. Both guide blocks 2 are fixed to a base 3.

[0024] An elastic member is disposed between the pair of clips 1. In this embodiment, the elastic member is a tension spring 9. The ends of the tension spring 9 are connected to tension spring connection bosses 91, which are disposed on the two clamping side plates 11. The elastic force of the tension spring 9 causes the pair of clip seats 12 to constantly move toward each other, thereby ensuring that the clamping portions of the pair of clips 1 are always able to clamp the container mouth.

[0025] A drive assembly is also provided on the base 3 between the pair of clip seats 12. This drive assembly drives the pair of clip seats 12 to translate synchronously outward under the guidance of the guide block 2, thereby driving the clamping portions of the pair of clamping side plates 11 away from each other. When the clip seats 12 translate back and forth under the guidance of the guide block 2, the clamping portions on the two clamping side plates 11 remain cocircular relative to the common center O. In this embodiment, each clamping side plate 11 is provided with an inwardly recessed arc-shaped receiving groove 112 on its inner side. Clamping protrusions are provided at each end of the receiving groove 112, forming the clamping portions for clamping the container. The clamping protrusions at each end of each receiving groove 112 are, from the inside to the outside, a first clamping protrusion 111 and a second clamping protrusion 113. When the clip seats 12 translate back and forth under the guidance of the guide block 2, the clamping protrusions on the two clamping side plates 11 remain cocircular relative to the common center O. In order to ensure the reliability of the container being clamped, the second clamping protrusion 113 is arranged at a position that ensures that: when the container with the smallest diameter is clamped, the force F between the second clamping protrusion 113 and the container mouth and the horizontal component force F generated by it are equal to each other. XThe angle α between them is controlled in the range of 15° to 80°. Figure 4 shown.

[0026] A wear-resistant mounting block 4 and a wear-resistant gasket 5 are arranged on the base 3 from bottom to top. The wear-resistant mounting block 4 includes a wear-resistant mounting block body 41. Two upward protrusions are arranged at intervals on the wear-resistant mounting block body 41. The two protrusions form a pair of guide blocks 2; a clip seat 12 of a pair of clips 1 is located between the wear-resistant mounting block body 41 and the wear-resistant gasket 5.

[0027] like Figure 2 As shown, the fixed connection structure between each guide block 2 and the base 3 includes: a stud 10, the stud 10 includes a nut 101, and the upper and lower ends of the nut 101 are respectively provided with an upper connecting column 102 and a lower connecting column 103, the nut 101 is blocked on the top of the wear-resistant gasket 5, and the lower connecting column 103 is passed through the wear-resistant gasket 5, the guide block 2 and the wear-resistant mounting block body 41 from top to bottom and is fixedly connected with the base 3 by thread, and the upper connecting column 102 is used to be fixed to the turntable 100, so that the translational container clamp can be suspended and fixed below the turntable 100, see Figure 6 The hanging fixed structure can significantly reduce the installation contact area between the container holder and the turntable 100, thereby effectively reducing sanitary blind spots and better meeting the requirements of aseptic filling.

[0028] like Figure 3 、 Figure 4 、 Figure 5 As shown, each guide block 2 has two straight side walls and arc-shaped ends. Each guide groove 13 includes a pair of straight guide groove side surfaces 131, and both ends of the pair of guide groove side surfaces 131 are arc-shaped guide groove end surfaces 132. The two side walls of each guide block 2 are respectively blocked by the pair of guide groove side surfaces 131 of the corresponding guide groove 13. Under the elastic force of the tension spring 9, the pair of clip seats 12 move closer to each other until the guide groove end surfaces 132 at the outer ends of the guide grooves 13 of the two clip seats 12 are respectively blocked by the outer ends of the corresponding guide blocks 2. Figure 4 This position is also the position for clamping the container with the smallest diameter.

[0029] The driving assembly can drive a pair of clip seats 12 to translate outward synchronously under the guidance of the guide block 2, thereby driving the clamping parts of a pair of clamping side plates 11 away from each other until the guide groove end faces 132 located at the inner ends of the guide grooves 13 of the two clip seats 12 are respectively blocked by the inner ends of the corresponding guide blocks 2.

[0030] Specifically, the drive assembly comprises an elongated drive block 7 disposed between a pair of clip seats 12. To improve the wear resistance of the drive block 7, a wear-resistant sleeve 73 is provided on the drive block 7. The drive block 7 is fixedly connected to a drive shaft 71. The lower end of the drive shaft 71 passes through the wear-resistant mounting block 4 and the base 3, allowing the drive shaft 71 to rotate on the wear-resistant mounting block 4 and the base 3. A connecting shaft 72 is provided on the drive block 7. The upper end of the connecting shaft 72 extends out of the wear-resistant washer 5. A nut 721 is provided on the connecting shaft 72 outside the wear-resistant washer 5.

[0031] The lower end of the drive shaft 71 is connected to a drive mechanism. Specifically, in this embodiment, the drive mechanism includes a drive arm 6 disposed below the base 3. The lower end of the drive shaft 71 extends out of the base 3 and is connected to the drive arm 6. The drive arm 6 is provided with a roller 61 for cooperating with a cam 8 fixed to the frame. Guided by the cam 8, the roller 61 drives the drive arm 6 to rotate the drive block 7, causing the ends of the wear-resistant sleeve 73 on the drive block 7 to push the clip seats 12 on either side thereof to move outward in a synchronous translation, thereby driving the clamping portions of the pair of clamping side plates 11 away from each other.

[0032] In a translational container clamp employing the above-described structure, the roller 61 on the drive arm 6, under the action of the cam 8, causes the drive block 7 to push the clip holders 12 on either side thereof to translate outward synchronously, thereby driving the clamping portions of the pair of clamping side plates 11 away from each other. This causes the clamping portions on the clamping side plates 11 to move away from each other, allowing the container mouth to enter between the clamping portions of the pair of clamping side plates 11 and be clamped. This structure has good compatibility. By simply changing the stroke of the cam 8, the distance between the clamping portions of the pair of clamping side plates 11 can be changed, thereby enabling the clamping of containers of different calibers. Furthermore, the position of the clamping center O of the container clamp of this structure remains constant.

[0033] As can be seen from the above, the translational container gripper described in this utility model has the following advantages: 1. A simple and ingenious structure with a significantly reduced number of parts, which significantly reduces blind spots during cleaning and thus significantly improves the cleanliness of the equipment. 2. Reliable gripping, high stability during container transfer, and good compatibility, including compatibility with a variety of containers of different calibers, thus avoiding frequent container gripper replacement and effectively saving production costs.
