Detailed Embodiment
[0016] In order to more clearly illustrate the purpose, technical solution and advantages of the embodiments of the present utility model, the present utility model will be further described below in conjunction with the drawings and embodiments. The description is clear and complete. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all embodiments.

In addition, the directional terms mentioned in the present utility model, for example, "upper", "lower", "front", "rear", "left", "right", "inner", "outer", etc., are only references to the directions of the attached drawings. The directional terms used are for better and clearer description and understanding of the present utility model, rather than indicating or implying the orientation that the present utility model must have. Therefore, it cannot be understood as a limitation to the present utility model.
[0017] An embodiment of the present utility model is as follows Figure 1As shown in the figure, a rotary tooling for cap processing includes a base 1. The base 1 is used to mount the rotary tooling on the turntable of the machine, so as to rotate with the turntable. At this time, an extension arm 13 that surrounds the base 1 for one week extends on the outer wall at the lower end of the base 1. A base through hole 130 is provided on the extension arm 13. The base 1 is mounted on the turntable by threading a bolt through the base through hole 130 and connecting it to the turntable with threads. Thus, the base 1 is mounted on the turntable. An installation hole 10 is provided at the top of the base 1. A mounting seat 2 for mounting the cap at the top is rotatably installed in the installation hole 10. The installation hole 10 is used to install the mounting seat 2. The mounting seat 2 can rotate in the installation hole 10. At the same time, the top of the mounting seat 2 is used to mount the cap 3. And the structure for positioning the cap 3 on the mounting seat 2 can be any existing structure for positioning the cap 3 in the cap 3 processing. The installation hole 10 is set as an installation through hole. The through hole facilitates the flow of gas in the installation hole 10 and can also effectively discharge the heat generated by friction. A mounting seat through hole that penetrates the upper and lower bottom surfaces of the mounting seat 2 and is coaxial with the installation hole 10 is also provided on the mounting seat 2. During the rotation of the mounting seat 2, a downward acting force will be generated on the cap 3 mounted on the top of the mounting seat 2, ensuring that the cap 3 is more firmly mounted on the mounting seat 2. The upper part of the mounting seat 2 protrudes from the top end of the installation hole 10, that is, the lower part of the mounting seat 2 is inside the installation hole 10 and the upper part is outside the installation hole 10, which is convenient for installing the cap on the mounting seat 2 and does not affect the rotation of the mounting seat 2 in the installation hole 10; A bearing 4 and a sealing ring 5 are arranged at intervals in the vertical direction between the outer wall of the lower part of the mounting seat 2 and the hole wall of the installation hole 10. The mounting seat 2 is fixedly installed in the bearing 4. The sealing ring 5 is sleeved on the mounting seat 2 and abuts against the inner wall of the mounting seat 2 or the installation hole 10. That is to say, a bearing 4 and a sealing ring 5 are sleeved on the lower part of the mounting seat 2. The bearing 4 is used to rotate in the installation hole 10, and the sealing ring 5 is used to increase the friction between the mounting seat 2 and the base 1 to form a resistance to prevent the mounting seat 2 from continuing to rotate under inertia. The sealing ring 5 is a rubber ring that can elastically deform. For example, the sealing ring 5 is arranged at the lower end edge of the mounting seat 2, and the bearing 4 is arranged at a position adjacent to the upper end edge in the upper part of the installation hole 10; For the installation of the bearing 4, the bearing 4 can be embedded in the installation hole 10, and the axis line of the bearing 4 and the axis line of the installation hole 10 are collinear; For the installation of the sealing ring 5, one method is to provide a clamping groove along the circumferential direction and around the inner wall of the installation hole 10 for one week, and then install the sealing ring 5 in the clamping groove. At this time, part of the sealing ring 5 protrudes outside the clamping groove, and then the mounting seat 2 is sleeved in the sealing ring 5 and abuts against the sealing ring 5. When the mounting seat 2 rotates by inertia, friction is generated between the mounting seat 2 and the sealing ring 5 to form a resistance to prevent the mounting seat 2 from continuing to rotate under inertia; Another situation is that the sealing ring 5 is sleeved on the mounting seat 2 with an interference fit and rotates with the mounting seat 2, and the sealing ring 5 abuts against the inner wall of the installation hole 10. During the rotation of the mounting seat 2, a resistance to prevent the mounting seat 2 from continuing to rotate under inertia can be generated between the sealing ring 5 and the inner wall of the installation hole 10;This can effectively prevent the excessive rotation of the mounting base 2 under inertia, enabling the bottle cap 3 to be accurately positioned on the mounting base 2. The sealing ring 5 is also convenient for installation and replacement, which is more conducive to use. The generated frictional force can act evenly on the mounting base 2 without affecting its use.
[0018] For further improvement, as Figure 1 shown in [reference], the base 1 includes a base 11 and a connecting member 12 in a cylindrical structure that can be detachably installed on the top of the base 11. The inside of the connecting member 12 forms the mounting hole of the base 1. In this way, when it is necessary to repair and replace the sealing ring 5 sleeved on the mounting base 2, the connecting member 12 and the base 11 can be disassembled to expose the sealing ring 5 for convenient repair and replacement. The detachable installation can be achieved by threaded connection or screwing the two together. At this time, a counterbore 110 coaxial with the connecting member 12 is provided at the top of the base 11 corresponding to the bottom surface of the connecting member 12. The sealing ring 5 is arranged corresponding to the counterbore position of the counterbore 110. The bearing 4 is arranged inside the connecting member 12 near the upper end of the connecting member 12. The bearing 4 is located in the middle of the mounting base 2, and the sealing ring 5 is located at the lower end of the mounting base 2, avoiding the shaking of the mounting base 2 during rotation. The counterbore 110 facilitates the disassembly and assembly of the sealing ring 5, and it can be set as a counterbore through hole.
[0019] For further improvement, as Figure 1 shown in [reference], the bearing 4 includes a thrust bearing 40 arranged at the upper end position inside the mounting hole 10 and a radial bearing 41 arranged below the thrust bearing 40. The inner diameter of the radial bearing 41 is smaller than that of the thrust bearing 40. In this way, the thrust bearing 40 is used to bear the axial thrust generated by the mounting base 2 due to the action of other forces, ensuring the stable operation of the mounting base 2. The radial bearing 41 is used to support and protect the mounting base 2, enabling it to operate normally in high-speed and heavy-load environments. The thrust bearing 40 is selected as a thrust ball bearing, and the radial bearing 41 is selected as a deep groove ball bearing. At this time, the connection structure between the mounting base 2 and the thrust bearing 40 is that a circumferential protrusion 20 extending radially outward along the upper part of the mounting base 2 and having a bottom abutting against the thrust bearing 40 is provided around the mounting base 2. The inner ring of the radial bearing 41 is fixedly sleeved on the outer wall of the lower part of the mounting base 2. Further, two radial bearings 41 are arranged at intervals. Both of the two radial bearings 41 are located below the thrust bearing 40. One of the radial bearings 41 is arranged near the thrust bearing 40, and the other is arranged near the sealing ring 5, so that the mounting base 2 will not shake when rotating in the mounting hole 10 and can always rotate in the vertical direction. The sealing ring 5 is arranged below the two radial bearings 41.
[0020] Although the present utility model has been described in detail above with general descriptions and specific embodiments, based on the present utility model, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present utility model all fall within the scope of protection required by the present utility model.
