Prelubricated rotary plug-feeding mechanism

Abstract

The invention provides a prelubricated rotary plug-feeding mechanism, and relates to the field of infusion bag production. The prelubricated rotary plug-feeding mechanism comprises a rack; a plug-conveying overturning assembly, a dipping lubrication assembly, a hose positioning assembly and a rotary plug-feeding assembly are mounted on the rack; the plug-conveying overturning assembly is providedwith a plug receiving station and a plug conveying station, the dipping lubrication assembly is provided with a dipping station and a lubrication station, the hose positioning assembly is provided with a positioning station, and the rotary plug-feeding assembly is provided with a lubrication station and a plug feeding station; the lubrication station of the rotary plug-feeding assembly is matchedwith the plug conveying station of the plug-conveying overturning assembly in position; the lubrication station of the dipping lubrication assembly is matched with the lubrication station of the rotary plug-feeding assembly in position; and the plug feeding station of the rotary plug-feeding assembly is matched with the positioning station of the hose positioning assembly in position. During working, sealing plugs are conveyed to the rotary plug-feeding assembly through the plug-conveying overturning assembly, lubricated through the dipping lubrication assembly and then rotatably stuffed intohoses located by the hose positioning assembly through the rotary plug-feeding assembly.

Description

technical field [0001] The invention provides a pre-lubricated rotary plugging mechanism and relates to the field of transfusion bag production. Background technique [0002] The conventional sealing plug insertion method is mechanical insertion, that is, the sealing plug is quickly inserted into the hose by driving the cylinder. This method can adapt to the combination of most sealing plugs and hoses, but the sealing plug is generally made of hard plastic. The material of the hose is very soft, and the sealing plug will inevitably damage the inner wall of the hose to varying degrees during the insertion process; and when the sealing plug is a soft sealing plug, the success rate of this plugging method will be greatly reduced, and it is basically impossible To meet the success rate of automated production, the most common way to deal with soft plugging is manual plugging, which can guarantee the success rate, but the speed is too slow, and the level of risk control is too lo...

Problems solved by technology

[0005] The sealing plug is mostly made of hard plastic, and the hose is mostly made of soft PP or other materials. During the pressing process, the sealing plug will inevitably crush and scratch the hose. In severe cases, the sealing plug will scrape the inner wall of the hose. The next layer of plastic debris, plastic debris will enter the liquid medicine, which poses a great risk during infusion; in addition, scratches on the hose will also affect the appearance of the product

[0006] When the sealing plug is made of soft material, the success rate of plugging with the above-mentioned plugging method is very low, and the friction between the soft sealing plug and the hose is greater than that of the hard sealing plug, so it is necessary to Lubricate the end of the sealing plug; at the same time, because the sealing plug is soft, the size of the sealing plug will be very close to the inner size of the hose (theoretically, the size of the sealing plug must be larger than the inner size of the hose to seal tightly, and the lubricant actually has a viscous Therefore, the size of the sealing plug can be slightly smaller than the inner size of the hose), and even the size of the sealing plug is larger than the inner size of the hose, so the requirements for the alignment of the sealing plug and the hose are very high, and the sealing plug is in the process of pressing Bending and other phenomena may occur. Therefore, the soft sealing plug is currently mainly used in the manual plugging method, and the efficiency is low.
