Embodiment 1
[0034] Such as figure 1 , figure 2 and image 3As shown, the support ring device of the needle seat sealing ring assembly machine of the safety self-destructing syringe is arranged on the base 1 between the feeding station and the sealing ring assembly station of the sealing ring assembly machine, and on the base 1 A turntable 2 is provided, and several sleeves 3 are vertically arranged at the edge of the turntable 2. The upper end of the sleeve 3 is conical, and the outer surface of the sleeve 3 has a ring-shaped groove 32. The sealing ring 5 is After being pushed down, the sealing ring 5 falls into the groove 32 , the depth of the groove 32 is very shallow, and the sealing ring 5 can be easily disengaged from the groove 32 after the sealing ring 5 falls into the groove 32 . A support rod 4 is provided in the sleeve 3, the upper end of the support rod 4 stretches out from the sleeve 3 and the minimum inner diameter of the rod body 42 of the support rod 4 is the same as th...
Embodiment 2
[0039] The content of embodiment 2 is basically the same as the content of embodiment 1, and its difference is, as Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the push ring mechanism includes a fixed shaft 8 fixed on the machine base 1, a support plate 9 and a lift cylinder 23 that drives the support plate 9 to move up and down. 8 A combination cylinder 10 that moves axially. The combination cylinder 10 is formed into a cylindrical shape surrounded by four push blocks 11. Each push block 11 is horizontally slidably connected to the support plate 9. There is a set between the fixed shaft 8 and the push block 11 When the support plate 9 moves down, the combined cylinder body 10 pushes the sealing ring 5 on the support rod 4 and separates the push block 11 horizontally. Two groups of elastic rings 12 are folded into a cylindrical shape. When the support plate 9 is in the original position, the combination cylinder 10 and the support rod 4 are separated from each...
