Problems solved by technology

The general assembly of the sealing ring is to expand the sealing ring and then put it on the needle seat. The traditional method is manual operation. The biggest disadvantage of manual operation is that the syringe is easy to attach germs, and it is inevitable that the needle will be damaged during the assembly process. The seat produces pollution, resulting in unqualified product hygiene requirements
On the other hand, the assembly speed of manual operation is also low, and it is difficult to adapt to the fierce market competition.

Embodiment 1

[0032] Such as figure 1, shown in Figure 2 and Figure 3, the support ring device of the needle seat sealing ring assembly machine of the safety self-destructing syringe is arranged on the support 1 between the feeding station of the sealing ring assembly machine and the sealing ring assembly station A turntable 2 is arranged on the machine base 1, and several sleeves 3 are arranged vertically at the edge of the turntable 2. The upper end of the sleeve 3 is conical, and a ring-shaped groove 32 is formed on the outer surface of the sleeve 3. After the sealing ring 5 is pushed down, the sealing ring 5 falls into the groove 32. The depth of the groove 32 is very shallow. After the sealing ring 5 falls into the groove 32, the sealing ring 5 can be easily removed from the groove. Slot 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 a...

Embodiment 2

[0037] The content of embodiment 2 is basically the same as the content of embodiment 1, and its difference is, as Figure 4 As shown, the ring-pushing mechanism includes a ring-pushing mechanism including a fixed shaft 21 fixed on the base 1, a support plate 9 and a lift cylinder 23 that drives the support plate 9 to move up and down. The combined cylinder 10 that moves axially relative to the fixed shaft 21, the combined 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, and the fixed shaft 21 and the push block 11 There is a separation structure between them when the support plate 9 moves down so that the combined cylinder 10 pushes the sealing ring 5 on the support rod 4 and the push block 11 is horizontally separated. Push block 11 is folded into two groups of elastic rings 12 of cylindrical shape. When the support plate 9 is in the original position, the combinat...

Abstract

The invention provides a ring supporting device of a machine for assembling a needle-stand sealing ring of a safety self-destruction syringe, which pertains to the field of medical apparatus and instruments and solves the technological problems of low hygiene and safety as well as low assembling speed of the existing hand-operated syringes. The ring supporting device of a machine for assembling a needle-stand sealing ring of a safety self-destruction syringe is arranged on a pedestal between a feeding station and a sealing-ring assembling station of the machine for assembling the needle-stand sealing ring; the pedestal is provided with a turnplate; a tubular sleeve with a tapered upper end is vertically fixed on the brim of the turnplate; a supporting rod is arranged in the sleeve; the upper end of the supporting rod is pyramidal and stretches out of the sleeve; the outer diameter of the rod body of the supporting rod is slightly smaller than or equal to the caliber of the upper end of the sleeve; a ring pushing mechanism which pushes the sealing ring on the supporting rod to the periphery of the sleeve is arranged above the sleeve. The ring supporting device expands but does no harm to the sealing ring and has simple structure, stable operation and high positioning accuracy.

Description

technical field [0001] The invention belongs to the technical field of medical machinery, and relates to a support ring device, in particular to a support ring device of a needle seat sealing ring assembly machine for a safety self-destruction syringe. Background technique [0002] The latest generation of disposable safe self-destructing syringes sold in the market generally includes a syringe body, a needle seat, a rubber stopper and a needle rod. , the front end of the needle pull rod is movably inserted into the needle cylinder body from the rear end of the needle cylinder body. After the liquid medicine in the syringe body is infused and used up, the front end of the needle pull rod is inserted into the needle holder, and the needle pull rod is pulled back, and the needle holder and the needle on it are pulled into the cylinder at the same time and the needle pull rod is in a certain position. The part is broken. In order to have a good seal between the needle seat an...
