Coil pipe and device for preparing coil pipe from pipe material

Abstract

The invention provides a coil pipe and a device for preparing the coil pipe from a pipe material. The device comprises a rotating disc, a fixing mechanism, a guiding mechanism, a driving mechanism anda control mechanism, the control mechanism is in communication connection with the driving mechanism, and the driving mechanism drives the rotating disc, the fixing mechanism and the guiding mechanism to move; and the periphery of the rotating disc is constructed to be in a vortex shape, the starting point and the ending point of the periphery are located in the same radial direction and locatedon the same side of the rotating center of the rotating disc, and the difference value between the radius at the ending point and the radius at the starting point is the same as the diameter of the pipe material. In the preparation process, one end of the pipe material is connected with the ending point, the coil pipe is directly and fixedly connected by the fixing mechanism at the working position of one side of the rotating disc, meanwhile, the guiding mechanism and the fixing mechanism are both located on the same side of the rotating disc, the extending direction of the pipe material is restrained, the control mechanism controls the driving mechanism to adjust motion states of the fixing mechanism and the guiding mechanism according to the rotating state of the rotating disc, thus theguiding mechanism restrains the extending direction of the pipe material to be kept unchanged, and the fixing mechanism is further always located in the working position.

Description

technical field [0001] The invention relates to the field of manufacturing technology, and particularly designs a coiled pipe and a device for preparing a pipe into a coiled pipe. Background technique [0002] After the production of minimally invasive interventional medical devices such as balloons, stents, and catheters, they need to be packaged and sealed in a hard tube to protect the product from damage caused by external forces and mechanical shocks such as transportation. However, in reality, the hard tube is long, which is not conducive to packaging and transportation. Therefore, the industry generally coils it up and shrinks it for use. [0003] At present, snap-on coils are generally used in the industry, that is, hard tubes are coiled in a vortex shape, and finally fixed with special clips. This type of coil is called a "snap-on coil". Buckles are a kind of fasteners, but they have protrusions and corners, so there is a risk of damaging the packaging bag, and the ...
