[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] like Figures 1 to 4 As shown, a bottle cap screwing head assembly for easy positioning includes a connecting head 1, a cap grabbing sleeve 2, a U-shaped groove 3, a push rod 4, a clamping steel ball 5, an open ring 6, an adjuster 7, a transverse through groove 8, a limit platform 9, a movable part 10, an oblique leak hole 11 and a protruding piece 12.

[0022] In the description of the present invention, unless otherwise specified, "multiple" means two or more; the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0023] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] like Figures 1 to 4 As shown, the lower end of the connector 1 is integrally formed with the capping jacket 2. Specifically, the upper end of the connector 1 is provided with threads, which can be fixedly connected to an automatic or semi-automatic capping machine.

[0025] A U-shaped groove 3 is provided at the lower end of the grab cover jacket 2, and the end of the elastic positioning grab cover device is movably connected in the U-shaped groove 3, and the elastic positioning grab cover device is movably arranged against the outer periphery of the grab cover jacket 2. Specifically, the elastic positioning grab cover device includes a push rod 4, a clamping steel ball 5, an open ring 6 and an adjuster 7. A plurality of mounting holes are provided at the lower end of the grab cover jacket 2, and the push rod 4 is adapted to be installed in the mounting holes, and the inner side of the push rod 4 is integrally formed with the clamping steel ball 5; a transverse through groove 8 is provided on the outer end surface of the push rod 4, and an open ring 6 is clamped on the transverse through groove 8, and the open end of the open ring 6 is in movably contact with the U-shaped groove 3; an adjuster 7 is provided on the inner side and above the clamping steel ball 5, and the adjuster 7 is evenly arranged in the circumferential direction and fixedly installed on the inner wall of the grab cover jacket 2.

[0026] The depth of the transverse through groove 8 is equal to the diameter of the open ring 6 , so that the open ring 6 can slide smoothly in the transverse through groove 8 .

[0027] There are at least three push rods 4, of which two push rods 4 are respectively close to the two sides of the U-shaped groove 3. In this embodiment, there are six push rods 4 evenly distributed. Specifically, the push rod 4 includes an integrally formed limit platform 9 and a movable part 10. The diameter of the limit platform 9 is larger than the diameter of the mounting hole. The inner side of the limit platform 9 is connected to one end of the movable part 10, and the other end of the movable part 10 is connected to the clamping steel ball 5, which is a hemispherical body.

[0028] The depth of the U-shaped groove 3 is greater than the radius of the clamping steel ball 5; the width of the U-shaped groove 3 is greater than the diameter of the limiting platform 9. Since the sizes of different bottle caps synchronously affect the expansion and contraction of the open ring 6 when screwing the caps, it can be ensured that bottle caps of different specifications can be limited inside the clamping steel ball 5 when screwing the caps, and the clamping steel ball 5 will not slip out of the range of the mounting hole.

[0029] In this embodiment, the push rod 4, the clamping steel ball 5 and the open ring 6 are all made of stainless steel. The open ring 6 can be easily removed when not in use, so as to facilitate the cleaning of the entire screw capping head assembly.

[0030] A plurality of oblique leak holes 11 are evenly arranged on the cover grabbing jacket 2, which can reduce the deadweight of the capping head assembly and facilitate cleaning.

[0031] A convex piece 12 is provided around the joint between the connector 1 and the capping sleeve 2 to facilitate the positioning of the connector 1 and the capping machine.

[0032] The working principle of the utility model is as follows: the connector 1 is installed on an automatic or semi-automatic capping machine, the capping machine is pressed downward, the bottle cap is squeezed by the lower end of the gripping cover 2 to clamp the steel ball 5 and is pressed into the regulator 7, the end of the clamping steel ball 5 will always fit the outer side of the bottle cap for positioning and limiting, thereby accurately screwing the cap.

[0033] The utility model has a simple overall structure, and the elastic positioning cover grabbing device is exposed and cooperates with the cover grabbing jacket 2. It is simple to position the bottle cap that needs to be screwed on, and can accurately limit the position for screwing on. The open ring 6 clamps the push rod 4 and the clamping steel ball 5 on the cover grabbing jacket 2 to prevent them from falling, thereby improving the stability of the cover grabbing.

[0034] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of rights of the present invention. Therefore, modifications, equivalent changes, improvements, etc. made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
