Automatic capping machine for dialyzate opening protective caps of hollow fiber type dialyzer

Abstract

The invention discloses an automatic capping machine for dialyzate opening protective caps of a hollow fiber type dialyzer. The automatic capping machine comprises a supporting table, a pressing and fixing device, feeding devices and capping devices, wherein the supporting table is used for supporting the horizontally-arranged hollow fiber type dialyzer with dialyzate openings facing downwards; the pressing and fixing device is located above the supporting table and fixes the dialyzer onto the supporting table through downward pressing; the feeding devices are located on the periphery of the supporting table and used for conveying the protective caps to the dialyzate openings of the dialyzer; the capping devices are located at the tail ends of the feeding devices and used for pressing the protective caps at the dialyzate openings of the dialyzer in a sleeved mode. The automatic capping machine is controlled by a programmable logic program to operate and makes the protective caps installed at the four dialyzate openings of the hollow fiber type dialyzer, automatic capping procedures are achieved, not only are a reliable capping process, extremely high capping efficiency and excellent capping tightness consistency are achieved, but also the capping procedures can be completed by taking up and putting down the dialyzer through only one worker, and labor intensity of operating personnel can be substantially lowered.

Description

technical field [0001] The invention belongs to the field of automatic mechanical equipment, and in particular relates to an automatic capping machine, in particular to an automatic capping machine suitable for the liquid port protection cap of a hollow fiber type dialyzer. Background technique [0002] In the medical field, using a dialyzer to perform dialysis of blood is a relatively safe, easy and widely used method of blood purification, which can properly prolong the life of patients. One of the hollow fiber dialyzers is currently the most clinically used dialyzer with the best effect. This type of hollow fiber dialyzer usually has a dialysate port and a blood port at its two ends, respectively. For dialysate and blood to enter and exit the dialyzer, in the manufacturing process of this type of hollow fiber dialyzer, the respective protective caps of the dialysate liquid port and the blood liquid port are installed on the liquid port through the capping process.

AI Technical Summary

Problems solved by technology

[0003] The current capping process generally adopts the method of manually picking and placing the dialyzer and manually capping. Although this manual capping method can complete the capping process, it has the disadvantages of high labor intensity, low capping efficiency, and tight capping. The disadvantage of poor consistency is increasingly unable to meet the modern high-efficiency, high-quality and humanized production needs
