Medical catheter winding rotary table used for automatic production

Abstract

The invention relates to a medical catheter winding rotary table used for automatic production. The medical catheter winding rotary table comprises a rotary table body with a cavity. Multiple centripetal slide grooves are formed in the upper end face of the rotary table body. Slide blocks capable of sliding in the centripetal slide grooves are installed in the centripetal slide grooves. Vertical through straight grooves are formed in the slide blocks. Bolts capable of sliding in the straight grooves are arranged in the straight grooves. Supporting rods vertically arranged are arranged above the slide blocks. The lower ends of the supporting rods are connected with the bolts through threads. A pressing rod vertically piercing into the cavity downwards is arranged on the rotary table body. A flange arranged in the cavity is arranged on the pressing rod. The pressing rod is sleeved with a spring. The two ends of the spring make contact with the flange and the lower end face of the cavity correspondingly. Multiple connection rods arranged in the cavity are installed on the pressing rod. Each connection rod corresponds to the corresponding centripetal slide groove in a one-to-one correspondence manner. One end of each connection rod is hinged to the pressing rod, and the other end of each connection rod is hinged to the corresponding slide block. The medical catheter winding rotary table is ingenious in structure, convenient and rapid to operate, not capable of causing the situation that it is difficult to take out catheters or surfaces of the catheters are damaged, and high in universality.

Description

technical field [0001] The invention relates to the technical field of medical device production equipment, in particular to a medical catheter winding turntable for automatic production. Background technique [0002] In the production process of medical catheters, in order to facilitate the storage, inventory and transportation of finished or semi-finished products, they usually need to be wound and packaged for the next step of the production process or out-of-warehouse operations. At present, there are many types of medical catheter winding equipment, but their core parts, namely the winding turntable, are similar. This type of winding turntable can wind the medical catheter around the support rod, and then make the wound medical catheter and the support rod The rod is separated so that the manipulator can remove the wound medical catheter for the next step; however, this type of winding carousel has the following disadvantages: [0003] Some winding carousels use the li...

AI Technical Summary

Problems solved by technology

[0003] Some winding carousels use the lifting of the pole to separate the coiled catheter from the pole. At this time, the catheter in a tight state will rub against the pole, making it difficult to take out the catheter or causing damage to the surface of the catheter and messing up the catheter ;

[0004] Some other winding carousels use the deflection of the pole to separate the coiled catheter from the pole, but the pole cannot be effectively fixed during the winding operation of this type of device, and the pole will deflect when the catheter is wound tightly , the coiled catheter is loose and irregular; due to its structural limitations, an additional positioning device needs to be installed to solve this problem. In addition, when the catheter is taken out after the coil is completed, it is necessary to separate the multiple poles. Only by operating can all the rods be separated from the catheter, which is not conducive to the efficiency of the automation process, and because the catheters are mostly made of soft materials with certain elasticity, they will deform after being wound tightly, and the catheter must first It can be completely separated from the support rod after recovering part of its elastic deformation. At this time, due to the large displacement of the upper part of the support rod when it deflects, the upper part of the support rod will be separated from the catheter while the lower part of the rod is still in contact with the catheter. The upper part has been rolled. The formed catheter has become loose or scattered, which affects the subsequent operation process

[0005] Moreover, the above-mentioned winding device generally has the problem of inconvenient adjustment. When it is necessary to adjust the winding radius of the catheter, multiple struts need to be adjusted separately, and the operation time of the process is too long, which affects the production efficiency.
