The capping assembly 300 includes a capping turntable 310, an upper turntable 320, a connecting shaft 330, a capping stop plate 340 and a capping group 350. The capping turntable 310 is slidably sleeved on the upper part of the lifting assembly 100, and the upper turntable 320 is arranged on the lifting assembly 100. 0, and is connected to the lifting and turning assembly 100 through a first slewing bearing 360, the capping turntable 310 and the upper turntable 320 are connected by a plurality of connecting shafts 330, the capping stop plate 340 is arranged below the capping turntable 310, and is connected to the capping turntable 310 through a connecting rod 370, the capping stop plate 340 is sleeved on the middle part of the lifting and turning assembly 100, and is gap-matched with the lifting and turning assembly 100, the capping groups 350 are divided into a plurality of groups, which are evenly arranged along the circumference of the capping turntable 310. The capping turntable 310 and the upper turntable 320 are connected into a whole through the connecting shaft 330, and the capping limiting plate 340 is connected to the capping turntable 310 through the connecting rod 370. When it is necessary to adjust the height of the capping limiting plate 340, it is only necessary to drive the upper turntable 320 through the lifting and rotating assembly 100 and then synchronously drive the capping turntable 310 and the capping limiting plate 340 to rise and fall as a whole. The operation is simple and quick, which improves the compatibility and practicality of the high-speed capping machine.
[0025] like Figure 1 and Figure 2 As shown, the lifting and rotating assembly 100 includes a mounting seat 110, a mounting sleeve 120, a lifting group 130, a rotating group 140 and a guide rail group 150. The mounting seat 110 is installed on the frame. The bottom end of the mounting sleeve 120 is connected to the top end of the mounting seat 110 through the inner ring of the second slewing bearing 160. The lifting group 130 passes through the mounting sleeve 120 and slides with the mounting sleeve 120. The top end of the lifting group 130 extends into the guide rail group 150 and is connected to the guide rail group 150. The rotating group 140 is sleeved on the mounting sleeve 120 and has a clearance fit with the mounting sleeve 120. The top end of the rotating group 140 extends into the guide rail group 150.

Specifically, the lifting shaft 131 is keyed with the installation sleeve 120; the lifting machine 132 can be manually controlled or electrically controlled.
[0028] When the height of the capping limiting plate 340 is adjusted, the lift 132 drives the lifting shaft 131 to move up and down, and then drives the upper turntable 320 to move up and down synchronously through the guide rail group 150, thereby driving the capping turntable 310 and the capping limiting plate 340 to move up and down as a whole.
[0029] like Figure 1 and Figure 2 As shown, the rotating group 140 includes an outer sleeve 141, a large gear 142, a small gear 143 and a rotating motor 144.

The fixed tank assembly 200 is sleeved in the middle of the outer sleeve 141. The capping turntable 310 is slidably sleeved on the upper part of the outer sleeve 141 through the sliding sleeve 145 and is located below the guide rail group 150. The bottom end of the outer sleeve 141 is connected to the outer ring of the second slewing bearing 160 through the large gear 142. The small gear 143 is meshed with the large gear 142.

Specifically, the outer sleeve 141 and the sliding sleeve 145 are key-fitted, that is, the sliding sleeve 145 can slide axially relative to the outer sleeve 141.
[0030] During capping, the rotating motor 144 drives the outer sleeve 141 to rotate through the small gear 143 and the large gear 142, thereby driving the capping turntable 310 and the lower turntable 210 in the can fixing assembly 200 to rotate together, and the guide rail assembly 150 does not rotate at this time.
[0031] like Figure 1 and Figure 3As shown, the cover pressing group 350 includes a pressure head 351, a first pressure rod 352, a first follower 353, a guide needle limiting ring 354, a second pressure rod 355, a second follower 356 and a cover limiting ring 357.

The pressure head 351 is installed at the bottom end of the first pressure rod 352, and the top end of the first pressure rod 352 is connected to the cover pressing guide rail 152 through the first follower 353. The guide needle limiting ring 354 is installed at the bottom end of the second pressure rod 355, and the top end of the second pressure rod 355 is connected to the guard plate guide rail 151 through the second follower 356. The cover limiting ring 357 is arranged directly above the guide needle limiting ring 354, and is connected to the bottom end of the cover removing limit plate 340 through the short shaft 358. Specifically, the pressure head 351 is a suction cup structure; the first follower 353 and the second follower 356 are both existing technologies.
[0032] like Figure 3 As shown, a plurality of guide sleeves 400 are installed at the edge of the upper turntable 320, and a guide shaft 500 is slidably installed in the guide sleeve 400, and the bottom end of the guide shaft 500 is connected to the first follower 353. Through the arrangement of the guide sleeve 400 and the guide shaft 500, the downward pressing of the pressure cover assembly 350 is limited and guided, and the accuracy of the downward pressing is further ensured.
[0033] like Figure 1 As shown, the tank fixing assembly 200 includes a lower turntable 210, a positioning plate 220 and a reduction motor 230. The lower turntable 210 is sleeved in the middle of the outer sleeve 141. There are a plurality of positioning plates 220, which are rotatably arranged on the edge of the lower turntable 210 along the circumferential direction. The output end of the reduction motor 230 is connected to the positioning plate 220. Specifically, the positioning plate 220 is magnetic.
[0034] During operation, the can cover feeding line conveys the can cover to the arc-shaped groove of the cover removing limit plate 340, and is adsorbed by the pressing head 351. The can body is magnetically attracted and adjusted into place by the positioning plate 220, and the rotating group 140 is started. The can cover is pressed onto the can body through the movement of the first follower 353 along the cover pressing guide rail 152 and the movement of the second follower 356 along the guard plate guide rail 151.
