Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0024] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0025] Examples, such as Figure 1-Figure 4 As shown, a plastic anti-capping capping machine includes a conveying mechanism 1, a capping mechanism 2 and a bracket 3. A positioning mechanism 11 is provided on the upper surface of the conveying mechanism 1, which can fix the bottle body at a position on the conveying mechanism 1 corresponding to the cover body of the capping mechanism 2; the positioning mechanism 11 is coaxially provided with a positioning base 111, an elastic member 112, and a base cover plate 113 from bottom to top, and a plurality of rotating clamps 114 are provided on the bottom cover plate. The bottle body is placed between the plurality of rotating clamps 114, so that the bottle body can be fixed to the positioning mechanism 11, and the bottle mouth corresponds to the capping part of the capping mechanism 2.

[0026] Furthermore, the positioning base 111 is fixed to the upper surface of the transmission mechanism 1 , and the center thereof corresponds to the pressing portion of the pressing mechanism 2 .

[0027] Among them, the capping mechanism 2 is arranged at the upper end of the bracket 3, connected to the upper end of the bracket 3 through two left and right cylinders and a connecting rod, and the start and stop of the capping mechanism 2 is controlled by the cylinder; the capping mechanism 2 is provided with a capping part at a position relative to the transmission mechanism 1, and the capping part can press and seal the cap body and the bottle body placed on the transmission mechanism 1. The utility model arranges a positioning mechanism 11 on the transmission mechanism 1, and a positioning base 111 of the positioning mechanism 11 is fixed on the upper surface of the transmission mechanism 1, and the positioning mechanism 11 is fixed relative to the transmission mechanism 1 by fixing the relative position of the center of the positioning base 111 with the transmission mechanism 1; since the device fixes the bottle body by rotating and fixing a plurality of rotating clamps 114 fixed relative to the positioning base 111, the relative position of the capping mechanism 2 and the center of the positioning base 111 can be adjusted to fix, and the relative position of the capping part of the capping mechanism 2 and the bottle body fixed on the positioning mechanism 11 can be fixed.

[0028] Furthermore, the positioning base 111 is provided with a plurality of symmetrically arranged positioning rods 115 ; the positioning base 111 is also provided with a cover groove 116 which is concentric with the positioning base 111 ; the base cover plate 113 can be fixedly connected to the positioning base 111 through the cover groove 116 .

[0029] The positioning rod 115 is used to rotationally fix the rotating clamp 114 and the positioning base 111 ; the positioning cover groove 116 fixes the base cover plate 113 on the positioning base 111 .

[0030] Furthermore, a positioning hole 117 through which the positioning rod 115 can pass is provided on the base cover 113 .

[0031] There is a base cover plate 113 between the rotating clamp 114 and the positioning base 111 , and the positioning rod 115 rotatably fixes the rotating clamp 114 and the positioning base 111 through the positioning hole 117 .

[0032] Furthermore, one end of the elastic member 112 is sleeved on a positioning rod 115 and is fixed through a fastening hole 118 provided on the base cover plate 113 .

[0033] The arrangement of the elastic member 112 can provide clamping stress when the rotating clamp 114 clamps the bottle body, thereby ensuring that the bottle body is fixed and positioned on the positioning mechanism 11 .

[0034] Furthermore, a plurality of rotating chucks 114 are centrally symmetrically sleeved on a positioning rod 115 passing through the base cover plate 113 . A threaded hole 1151 is provided in the positioning rod 115 , and the rotating chucks 114 are fixed by screws and the threaded hole 1151 .

[0035] Furthermore, the positioning base 111 and the base cover 113 are both circular. The positioning base 111 and the base cover 113 are set to be circular, and the center of the circle is the positioning center.

[0036] Furthermore, the contact surface between the rotating clamp 114 and the bottle body is an arc surface.

[0037] Among them, the contact surface between the rotating clamp 114 and the bottle body is an arc surface, which can ensure that the bottle body will not be scratched when clamping the bottle body; the end of the rotating clamp 114 away from the bottle body is in active contact with the outer periphery of the positioning base 111, and when the bottle body is clamped between multiple rotating clamps 114, each rotating clamp 114 rotates around its own positioning rod 115 as the center, and the end of the rotating clamp 114 contacting the bottle body and the end away from the bottle body rotate at opposite angles. When the bottle body enters between the multiple rotating clamps 114, the rotating clamp 114 stops rotating to clamp the bottle body.

[0038] The device is provided with at least three rotating clamps 114 , and the three rotating clamps 114 can ensure that the bottle body is positioned and fixed.

[0039] Furthermore, the rotating clamp 114 is made of rubber, plastic or a plastic material. The above flexible material can further prevent the bottle body from being scratched when being clamped by the rotating clamp 114.

[0040] Furthermore, the elastic member 112 is any one of an iron wire, a spring, and an elastic rope.

[0041] Furthermore, the height of the positioning rod 115 can be adjusted to adjust the rotating clamp 114 that adapts to the bottle body; for a regularly shaped bottle body, the bottle body or bottle mouth can be clamped by the rotating clamp 114 to fix and position it; for a special-shaped bottle or an irregularly shaped bottle body, the bottle mouth can be clamped by the rotating clamp 114 to fix and position it.

[0042] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
