When using a regular capping head to tighten the irregularly shaped cap, the overlap edge will collide with the capping head and be damaged. There is an urgent need for a three-claw capping head that is suitable for irregularly shaped caps and will not damage the overlap edge. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a three-claw capping head suitable for irregularly shaped caps.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: a three-claw capping head suitable for irregularly shaped caps, comprising: a vertically arranged connecting sleeve, characterized in that: an annular mounting boss is provided on the outer side of the lower part of the connecting sleeve, and three vertical upper threaded holes are provided on the upper surface of the mounting boss, the centers of the three upper threaded holes are on the same circle, and the three upper threaded holes are arranged at 120 degrees to each other around the connecting sleeve, and a hinge groove is provided below each upper threaded hole, the hinge groove is located on the mounting boss, and its lower side is provided. The device is open and also features a screw-on sleeve. The screw-on sleeve has an inner cavity for accommodating the overlapping edge of an irregularly shaped cap. An annular clamping platform is located at the entrance of the inner cavity of the screw-on sleeve to hold the irregularly shaped cap. Anti-slip teeth are provided on the inner wall of the annular clamping platform. A pressure plate is located inside the inner cavity of the screw-on sleeve to press down the irregularly shaped cap. The screw-on sleeve is divided into three equal parts around its axis, forming three screw-on claws. Each of the three screw-on claws is located below a three-threaded hole. A hinge block is located at the upper end of each of the three screw-on claws, and the three hinge blocks are inserted into three hinge slots. In the process, three hinge shafts are inserted into the mounting boss, passing through three hinge blocks respectively, allowing the three cap claws to be hinged to the bottom of the connecting sleeve. When the three cap claws swing outwards to open, they can avoid the overlapping edge of the irregularly shaped cap; when they swing inwards, they can be joined together to form a cap sleeve. Each of the three cap claws has a horizontal threaded hole on its outer wall. A vertical bolt is threaded into each of the three upper threaded holes, and a horizontal bolt is threaded into each of the three lower threaded holes. Each bolt is threaded with two... There are three nuts, three vertical bolts, and three horizontal bolts, each corresponding to a specific bolt. A tension spring is installed between the corresponding vertical and horizontal bolts. The two ends of the tension spring are connected to the heads of the two corresponding bolts and are clamped by a nut on each bolt. Another nut on each bolt is used to tighten the bolt. Under the action of the tension spring, the three cap claws will swing outward to open. When the pressure plate on the cap claw moves down with the three cap claws and is pressed against the irregular cap, the three cap claws can overcome the tension of the tension spring and swing inward to hold the irregular cap.

[0005] Furthermore, in the aforementioned three-claw capping head suitable for irregularly shaped caps, three mounting notches are machined on the side wall of the mounting boss, and three hinge shafts are respectively inserted vertically into the mounting boss from the planar side wall of the three mounting notches.

[0006] Furthermore, in the aforementioned three-jaw capping head suitable for irregularly shaped caps, each threaded hole is connected to a corresponding hinge groove, and each vertical bolt extends downward into the hinge groove so that the upper end of the capping claw can abut against it. The angle at which the capping claw swings outward can be adjusted by adjusting the extension distance of the vertical bolt.

[0007] Furthermore, in the aforementioned three-claw capping head suitable for irregularly shaped caps, each hinge shaft has an annular positioning groove machined at its tail end. After each hinge shaft is inserted into the mounting boss, it is positioned by a positioning bolt that is screwed vertically into the mounting boss and pinned into the annular positioning groove on the hinge shaft, so that the hinge shaft cannot detach from the mounting boss.

[0008] Furthermore, in the aforementioned three-claw capping head suitable for irregularly shaped caps, the cross-section of the annular positioning groove is V-shaped.

[0009] The advantages of this utility model are as follows: When the three capping claws of the three capping heads swing outward to open, they can avoid the overlapping edge of the irregularly shaped cap. When the pressure plate on the capping claws is pressed against the irregularly shaped cap as the three capping claws move down, the three capping claws can overcome the tension of the tension spring and swing inward to hold the irregularly shaped cap. At this time, the overlapping edge of the irregularly shaped cap can be located in the inner cavity of the capping sleeve, so that the overlapping edge will not be damaged when the capping head is capping.
