Problems solved by technology

[0004] At present, most of the processes for producing such sheathed syringes on the market use different equipment to produce the components of the sheathed syringes separately, and then assemble them manually. This production process cannot achieve mass continuous production of products, and the degree of mechanization is not high. Most of them adopt semi-automatic or manual assembly. At the same time, in the production process of sheathed syringe components, it is easy to have unqualified products and poor interchangeability in the assembly of the next process.

Embodiment 1

[0039] The invention provides a kind of production technology of sheath syringe, comprises the following steps:

[0040] Assembly of rubber plug and push rod: Send the push rod and rubber plug to a fixed position through the feeding device, and insert the push rod into the rubber plug by rotating the vertical drop;

[0041] A2. Assembling of the cylinder body: the push rod is rotated and assembled with the position of the cylinder rotating disc, and then transferred to the next process through the rotating disc;

[0042] A3. Sheath assembly: Turn the assembled cylinder to the place where it overlaps with the sheath up and down through the turntable, and the cylinder falls into the sheath, and then transfers to the next process through the turntable;

[0043] A4. Cover assembly: turn the product on the upper turntable to a fixed position and cover the cover;

[0044] A5. Welding: transfer the product to the welding part through the chute or through the product flow channel, an...

Abstract

The invention relates to production processes of syringes, in particular to a production process of a sheath syringe.The production process comprises the steps that A1, a rubber plug and a push rod are assembled; A2, a barrel is assembled; A3, a sheath is assembled, wherein the assembled barrel is transferred to the position where the barrel and the sheath are vertically overlapped through a rotary disc, and the barrel falls into the sheath and transferred to the next procedure through the rotary disc; A4, a protection cover is assembled, wherein the product on the last rotary disc is transferred to the fixed position and covered with a protection cap; A5, welding is carried out, wherein the product passes through a chute and is transferred to the welding position through a product flow channel, a protection cover is welded through a welding head, the protection cover and the sheath are firmly welded, the product is discharged, a chain mechanism serves as a transmission mechanism, and gear and rack transmission is adopted as the transmission mode; A6, discharging is carried out.The production process of the sheath syringe is high in mechanization degree, production efficiency and yield.

Description

technical field [0001] The invention relates to a production process of a syringe, in particular to a production process of a sheathed syringe, and belongs to the field of medical technology. Background technique [0002] Syringes are a common medical appliance. As early as the 15th century, Italian Catinel proposed the principle of syringes. The emergence of the syringe is an epoch-making revolution in the field of medical equipment and the process of needle extraction or injection of gas or liquid is called injection. The syringe consists of a syringe with a small hole at the front end and a matching piston core rod, which is used to inject a small amount of liquid or inject it into areas that are inaccessible by other methods or withdraw it from those places. When the core rod is pulled out, the liquid Or the gas is inhaled from the small hole at the front of the syringe, and the liquid or gas is squeezed out when the core rod is pushed in. [0003] The sheathed syringe...
