A hydraulic rod 22 is fixedly connected to the top lower end wall of the bracket 21, and a cutter 23 is fixedly connected to the bottom of the hydraulic rod 22. A rotating motor for driving the cutter 23 to rotate is installed at the bottom of the hydraulic rod 22. Another rotating motor is also installed at the bottom of the operating table 20. All rotating motors are electrically connected to power supplies. This is an existing technology and will not be described in detail here.

[0026] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, a clamping structure is provided on the top of the operating table 20, and the clamping structure includes a bottom rod 42 and an upper rod 46. The bottom rod 42 is rotatably connected to the top of the operating table 20, and the upper rod 46 is also rotatably connected to the top of the operating table 20. The clamping structure can clamp the bottle cap on the top of the operating table 20.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the bottom rod 42 and the upper rod 46 are both rectangular rods, the position of the cutter 23 is aligned with the end of the upper rod 46, the clamping structure also includes a rotating shaft 40, a screw hole 41 and a blocking rod 43, the rotating shaft 40 is rotatably connected to the top of the guard ring 30, the screw hole 41 is opened at the top of the rotating shaft 40, the bottom rod 42 is fixedly connected to the wall surface of the rotating shaft 40, and the blocking rod 43 is fixedly connected to the side wall surface of the bottom rod 42, the clamping structure also includes a live shaft 44, a through groove 45 and a bolt 47, the live shaft 44 is rotatably connected to the top of the rotating shaft 40, the through groove 45 penetrates and is opened at the top of the live shaft 44, the upper rod 46 is fixedly connected to the wall surface of the live shaft 44, the bolt 47 is rotatably connected in the through groove 45, the live shaft 44 and the rotating shaft 40 are cylindrical with the same size, and the live shaft 44 is at the top of the rotating shaft 40 The bottom rods 42 are stacked, and a plurality of bottom rods 42 are arranged in a circular array on the arc surface of the rotating shaft 40. The upper rods 46 are also arranged in a circular array on the arc surface of the movable shaft 44. The number of the upper rods 46, the bottom rods 42 and the blocking rods 43 is the same. The blocking rods 43 are arc-shaped rods. The bolts 47 can pass through the through grooves 45 and be threadedly connected in the screw holes 41. The clamping structure also includes a guard ring 30, an inlet groove 31, an outlet groove 32, a guide path 33, a collection tube 34 and a top block 35. The guard ring 30 is fixedly connected to the top of the operating table 20. The inlet groove 31 is opened on the front wall surface of the guard ring 30, the outlet groove 32 is opened on the side wall surface of the guard ring 30, the guide path 33 is fixedly connected to the front wall surface of the operating table 20, the collection tube 34 is clamped on the side wall surface of the operating table 20, and the top block 35 is fixedly connected to the top of the operating table 20.

[0028] When in use, the rotating motor at the bottom of the operating table 20 can drive the rotating shaft 40 to rotate, the bottle cap to be trimmed is placed with the opening facing upward on the top of the guide path 33, and the power is turned on. At this time, the rotating shaft 40 will rotate, and the rotating shaft 40 can drive the bottom rod 42, the blocking rod 43, the movable shaft 44, the upper rod 46 and the bolt 47 to rotate at the same time. When the bottle cap at the top of the guide path 33 moves to the angle formed by the upper rod 46 and the bottom rod 42, it will rotate at the top of the operating table 20 with the rotating upper rod 46 and the bottom rod 42. When the bottle cap does not move to the wall of the blocking rod 43, it will be blocked by the blocking rod 43. When the bottle cap is driven to the bottom of the cutter 23 by the upper rod 46 and the bottom rod 42, the high-speed rotating cutter 23 will cut the bottle cap. The burrs on the bottle caps are removed by cutting, and then the bottle caps with the burrs removed will continue to be rotated by the bottom rod 42 and the upper rod 46, and will directly fall into the receiving tube 34 when rotating to the outlet groove 32, so that the trimming of the bottle caps is completed. When it is necessary to trim the bottle caps of different sizes, the bolts 47 are first rotated to be loose, and the movable shaft 44 can be adjusted and rotated at the top of the rotating shaft 40. At this time, the movable shaft 44 can be rotated, and the movable shaft 44 will drive the upper rod 46 to rotate at the same time when rotating, thereby adjusting the angle between the upper rod 46 and the bottom rod 42 to adapt to the diameter of the bottle caps that need trimming. After the angle between the upper rod 46 and the bottom rod 42 is adjusted, the bolts 47 are tightened again at the top of the movable shaft 44;

[0029] In summary, by setting up a clamping structure, bottle caps of different sizes can be adapted, because the clamping structure can adjust the angle between the upper rod 46 and the bottom rod 42 that fix the bottle caps, so that bottle caps of different diameters can be fixed on the top of the operating table 20 for trimming and trimming. The hydraulic rod 22 can drive the cutter 23 to rise and fall to adapt to bottle caps of different heights. Therefore, compared with the prior art, the application scope of this solution is wider.

[0030] like Figure 2 As shown, the guard ring 30 is in a circular ring shape, the rotating shaft 40 and the movable shaft 44 rotate at the top of the operating table 20 in the center of the guard ring 30, the length of the upper rod 46 and the bottom rod 42 is less than the radius of the guard ring 30, the cross section of the guide path 33 is in a concave shape, the top opening of the guide path 33 is consistent with the size of the inlet groove 31 and is connected, the collection tube 34 is a hollow cylinder with an open top, the top opening of the collection tube 34 is aligned with the outlet groove 32, the top of the top block 35 is in an inclined shape, the cross section of the top block 35 is a right triangle, the top block 35 is fixedly connected to the top of the operating table 20 in the cavity of the guard ring 30, and the height of the top block 35 is flush with the bottom of the bottom rod 42;

[0031] In specific use, after the bottle cap is driven by the upper rod 46 and the stopper rod 43 and trimmed by the cutter 23, it will move along the inclined surface of the top block 35 and enter the cavity of the receiving tube 34;

[0032] In summary, by providing the top block 35, the bottle cap can be lifted up to prevent the bottle cap from being stuck on the top of the operating table 20 and affecting the trimming of other bottle caps, thereby increasing the stability of the device operation.

[0033] Working principle: place the bottle caps to be trimmed with their openings facing upwards on the top of the guide path 33, and turn on the power supply. At this time, the rotating shaft 40 will rotate, and the rotating shaft 40 can drive the bottom rod 42, the baffle rod 43, the movable shaft 44, the upper rod 46 and the bolt 47 to rotate at the same time. When the bottle caps at the top of the guide path 33 move to the angle formed by the upper rod 46 and the bottom rod 42, they will rotate at the top of the operating table 20 at the same time as the rotating upper rod 46 and the bottom rod 42. When the bottle caps do not move to the wall of the baffle rod 43, they will be blocked by the baffle rod 43. When the bottle caps are driven by the upper rod 46 and the bottom rod 42 to the bottom of the cutter 23, the high-speed rotating cutter 23 will cut the bottle caps to remove the burrs on the bottle caps. Then, the bottle caps with the burrs removed will continue to be rotated by the bottom rod 42 and the upper rod 46, and will directly fall into the receiving tube 34 when they rotate to the outlet groove 32.
