[0027] The number of moving plates in the ring barrier is multiple, but an empty position is always kept in the ring barrier, so that the push cylinder drives the push plate to push the moving plate at the corresponding position, so that the moving plate is pushed to move forward, and the feeding function is completed.

[0028] As Figure 2 , the feeding assembly 2 includes a vertical plate 21 fixed on the operating table 1, the back of the vertical plate 21 is installed with a feeding cylinder 22 and two guide rods 23 fixed on the inner side, the piston rod of the feeding cylinder 22 is fixed with a sliding plate 24 penetrating the two guide rods 23, the bottom of the sliding plate 24 is installed with an ejection cylinder 25, the piston rod of the ejection cylinder 25 is fixed with an ejection plate 26, and the bottom of the ejection plate 26 is installed with two groups of first pneumatic clamps 27. The sliding plate is stably reciprocated under the action of the guide rods by the feeding cylinder, so that the first pneumatic clamps can be moved together, and the valve seat can be placed on the corresponding limiting seat by cooperating with the ejection cylinder to retract, and then the valve core is moved to the valve seat to be placed by reciprocating operation, and the feeding operation is completed.

[0029] As Figures 3-4 , the cleaning assembly 3 includes a side plate 31 fixed on the operating table 1, an upper pushing cylinder 32 and an upper pushing block 33 fixed with the piston rod of the upper pushing cylinder 32 are installed on the right side of the side plate 31, the upper pushing block 33 is installed with a frame plate 38, and two groups of inclined air pipes 313 are installed on the inner side of the frame plate 38. When the limiting seat moves to the lower side of the air pipe, the upper pushing block is lowered to the appropriate position by the upper pushing cylinder, the air outlet of the air pipe is opposite to the connection position of the valve seat and the valve core, so that the impurities at the thread can be cleaned, and the excess moisture can be dried by blowing.

[0030] The top of the up pushing block 33 is slidably connected with a slide pushing block 34, the frame plate 38 is fixed on the slide pushing block 34, the first adjusting rod 35 is threadedly connected on the up pushing block 33, and one end of the first adjusting rod 35 is rotatably connected with the slide pushing block 34.
