The cavity surface of the clamping cavity 302a is tapered, and the horizontal cross section of the clamping cavity 302a gradually decreases from the lower end to the upper end, so that the clamping cavity 302a can match cap bodies of different sizes. A plurality of convex points are arranged on the cavity surface of the clamping cavity 302a, so as to increase the friction between the cavity surface of the clamping cavity 302a and the cap body, and thus the cap body can be better screwed onto the filling bottle.

[0039] Embodiment 2

[0040] For the second embodiment of the present application, the difference between the second embodiment and the first embodiment is that the rotating cap head 302 is detachably mounted on the output end of the rotating cap motor 301, so as to facilitate replacement of the rotating cap head 302 of different specifications to match cap bodies of different sizes.

[0041] The output end of the rotating cap motor 301 is fixedly connected with a second connecting portion 304, and the upper end surface of the rotating cap head 302 is fixedly connected with a first connecting portion 303. The first connecting portion 303 is detachably connected to the second connecting portion 304.

[0042] Please refer to Figures 3 to 6 The first connecting portion 303 is provided with an assembly hole, and the end portion of the second connecting portion 304 can be assembled into the assembly hole of the first connecting portion 303. A positioning plunger 308 is movably arranged between the upper end of the second connecting portion 304 and the first connecting portion 303. A plurality of arc-shaped recesses 308a are formed in the positioning plunger 308 near the end close to the second connecting portion 304 along the circumferential surface, and the arc-shaped recesses are matched with a positioning bead 307. A plurality of limiting through holes 304a are formed in the outer surface of the second connecting portion 304 near the positioning plunger 308, and the limiting through holes 304a are used for limiting the positioning bead 307. A plurality of clamping recesses 303b are arranged on the hole wall of the assembly hole, and the clamping recesses 303b are matched with the arc-shaped recesses 308a. The clamping recesses 303b, the limiting through holes 304a and the arc-shaped recesses 308a cooperatively limit the positioning bead 307. The positioning bead 307 moves to fill or separate from the clamping recesses 303b, so as to realize assembly and disassembly between the first connecting portion 303 and the second connecting portion 304.

[0043] Further, a spiral beryllium copper wire 309 is arranged between the positioning plunger 308 and the first connecting portion 303, so as to stagger the clamping recesses 303b and the limiting through holes 304a, and thus the positioning bead 307 can move.

[0044] When the positioning beads 307 are not trapped, the positioning beads 307 are in the arc-shaped recessed opening 308a and the limiting through opening 304a; when the positioning beads 307 are trapped, the clamping recessed opening 303b moves up and down, the positioning beads 307 move to one side away from the arc-shaped recessed opening 308a and between the outer surface of the positioning plunger 308 and the clamping recessed opening 303b, so that the second connecting part 304 can be assembled in the first connecting part 303 through the positioning beads 307, and several positioning beads 307 can be assembled between the second connecting part 304 and the first connecting part 303 to realize the transmission assembly of the two, so that the rigid connection directly acting on the cover can be avoided, which can be possible to the cover on the filling bottle transition screw.

[0045] Please refer to Figure 3 and Figure 4 , the outer surface of the second connecting part 304 and the hole wall of the first connecting part 303 assembly hole are provided with mutually matched embedded grooves; the two embedded grooves are filled with deformable silica gel cylinders 306; the silica gel cylinders 306 and the positioning beads 307 are arranged at intervals, so that the assembly depth of the second connecting part 304 in the first connecting part 303 can be controlled, and the specific number of silica gel cylinders 306 and positioning beads 307 is determined according to the actual situation; the silica gel cylinders 306 arranged between the second connecting part 304 and the first connecting part 303 can eliminate the influence of external force, so that the assembly between the second connecting part 304 and the first connecting part 303 can be more compact. The positioning plunger 308 in the second connecting part 304 moves downward under the action of the spiral beryllium copper wire 309, and the positioning beads 307 move to one side, so that the positioning beads 307 are filled in the clamping recessed opening 303b to realize the tight trapping, and the positioning beads 307 arranged on the second connecting part 304 continue to move up and down.

[0046] Further, please refer to Figure 3 and 5 , the clamping recessed opening 303b is a circular arc matched with the outer surface of the positioning bead 307, and the radius of the positioning bead 307 is smaller than the radius of the clamping recessed opening 303b, so that the positioning bead 307 can make a combined movement of up and down and circumferential with a small distance d, so that the rigid assembly connection between the second connecting part 304 and the second connecting part 304 can be avoided.

[0047] Please refer to Figures 3 to 5As shown, the cap screwing motor 301 transmits the shaking to the second connecting part 304 through the first connecting part 303, and the shaking transmitted can be offset through the silica gel cylinder 306 on the second connecting part 304, so as to reduce the shaking of the cap screwing body. Since the positioning bead 307 on the second connecting part 304 can make the combined movement of up and down and axial movement with a small distance d relative to the first connecting part 303, the rigid assembly connection between the second connecting part 304 and the second connecting part 304 can be avoided, the shaking can be offset through the silica gel cylinder 306, and the shaking of the cap screwing motor 301 is avoided from being transmitted to the second connecting part 304.

[0048] When the cap screwing motor 301 is started, the first connecting part 303 is driven to rotate through the output end thereof, the first connecting part 303 can drive the silica gel cylinder 306 to deform, so as to offset the shaking transmitted by the cap screwing motor 301, the first connecting part 303 can drive the second connecting part 304 to rotate relatively, so that the circumferential distance d between the positioning bead 307 on the second connecting part 304 and the clamping recess 303b on the first connecting part 303 is 0. Since the positioning bead 307 cannot move radially, the first connecting part 303 drives the second connecting part 304 to rotate. When the screwing process is completed, the circumferential distance d between the positioning bead 307 on the second connecting part 304 and the clamping recess 303b on the first connecting part 303 is restored to the initial state under the action of the deformation force of the silica gel cylinder 306. In this way, the cap screwing motor 301 is connected to the cap screwing head 302 in the mounting mode, which not only facilitates the replacement of the cap screwing head 302, but also offsets the shaking transmitted by the cap screwing motor 301. The installation structure is simple, convenient to disassemble and assemble, and can offset the shaking transmitted by the cap screwing motor 301 and avoid the influence of the cap screwing head 302 on the cap body.

[0049] The end of the second connecting part 304 close to the positioning plunger 308 is arranged in a gradient, so as to limit the movement position of the positioning plunger 308. The upper part of the second connecting part 304 is provided with a gradient channel, including a front channel and a rear channel arranged in sequence from the port inward, and the limiting opening 304a is arranged on the front channel. The positioning plunger 308 includes a guide part and a force providing part, and the cross-sectional diameter of the guide part is smaller than that of the force providing part. The guide part is movably arranged in the rear channel, and the arc-shaped recess 308a is arranged on the guide part. When the positioning bead 307 is trapped, the front end surface of the force providing part is clamped at the port of the rear channel.

[0050] Further, the first slope surface is arranged at the joint of the guiding part and the force providing part; the second slope surface is arranged at the lower end of the limiting through hole 304a, facing the side of the first slope surface; when the positioning bead 307 needs to be confined, the first slope surface and the second slope surface are tightly attached to each other, the action force between the first slope surface and the positioning bead 307 is decomposed, and the action force for pushing the positioning bead 307 to one side is obtained through the first slope surface.

[0051] Further, the first slope surface is arranged at the joint of the guiding part and the force providing part; the second slope surface is arranged at the lower end of the limiting through hole 304a, facing the side of the first slope surface; when the positioning bead 307 needs to be confined, the first slope surface and the second slope surface are tightly attached to each other, the action force between the first slope surface and the positioning bead 307 is decomposed, and the action force for pushing the positioning bead 307 to one side is obtained through the first slope surface.

[0052] Further, the first slope surface is arranged at the joint of the guiding part and the force providing part; the second slope surface is arranged at the lower end of the limiting through hole 304a, facing the side of the first slope surface; when the positioning bead 307 needs to be confined, the first slope surface and the second slope surface are tightly attached to each other, the action force between the first slope surface and the positioning bead 307 is decomposed, and the action force for pushing the positioning bead 307 to one side is obtained through the first slope surface. Figure 4

[0053] Further, the first slope surface is arranged at the joint of the guiding part and the force providing part; the second slope surface is arranged at the lower end of the limiting through hole 304a, facing the side of the first slope surface; when the positioning bead 307 needs to be confined, the first slope surface and the second slope surface are tightly attached to each other, the action force between the first slope surface and the positioning bead 307 is decomposed, and the action force for pushing the positioning bead 307 to one side is obtained through the first slope surface.

[0054] ​When it is necessary to replace the screw cap 302, other spikes are used to extend through the socket 303a into the disengagement port 308b on the positioning plunger 308, and the positioning plunger 308 is moved in the compression direction of the spiral beryllium copper wire 309, so that the positioning bead 307 slides into the arc-shaped recess 308a, thereby the first connecting portion 303 and the second connecting portion 304 can be detached from each other.
