Automatic rotating polyurethane filament taking and releasing device and method

Abstract

The invention provides an automatic rotating polyurethane filament taking and releasing device. The device comprises a frame, wherein a filament supporting mechanism, a shifting fork mechanism and a filament taking and releasing mechanism are arranged on the frame, the filament supporting mechanism comprises a filament supporting rod and a slide rail which is fixedly mounted on the frame in the transverse direction, a first driving air cylinder is glidingly mounted on the slide rail, the filament supporting rod is fixedly mounted at the output end of the first drive air cylinder in the transverse direction, and a second driving air cylinder used for driving a slider to move left and right is fixedly mounted on the frame; the shifting fork mechanism comprises a shifting fork used for shifting polyurethane filament coils on the filament supporting rod and a guide rail allowing the shifting fork to move left and right; and the filament taking and releasing mechanism comprises a rotating air cylinder fixedly mounted on the frame at the end part of the filament supporting rod, a filament taking and releasing air cylinder is fixedly mounted at the output end of the rotating air cylinder,and a pneumatic clamping jaw used for winding and releasing polyurethane filaments is fixedly mounted at the output end of the filament taking and releasing air cylinder. The device is reasonable indesign, high in degree of automation and capable of performing rapid and efficient filament taking and releasing, facilitates following automatic packaging and reduces the labor cost.

Description

technical field [0001] The present invention relates to the technical field of spandex production and manufacturing, in particular to a spandex yarn automatic rotating spinning take-off and unwinding device, and also relates to a spinning and unwinding method of the above-mentioned spandex automatic spinning spin taking and unwinding device. Background technique [0002] The full name of spandex fiber is the abbreviation of polyurethane fiber, which is polymerized by PTMEG and MDI. It is a modern clothing industrial material and clothing fabric. Spandex filament is covered with short fiber yarn, that is, spandex core-spun yarn. The elastic fabric woven with it is comfortable, fit, and has strong elasticity. It has the reputation of the second skin of the human body. [0003] At present, during production, spandex filaments are wound into cylindrical, hollow filament rolls, which are convenient for transportation and packaging. However, in actual production, in order to save ...

Problems solved by technology

[0003] At present, during production, spandex filaments are wound into cylindrical, hollow filament rolls, which are convenient for transportation and packaging. However, in actual production, in order to save space and improve efficiency, several spandex filament coils are usually Put them side by side vertically and transport them outward, so that in the subsequent packaging process, workers first need to manually separate several spandex rolls arranged vertically side by side into a single spandex roll placed horizontally, which greatly increases the workload of workers. And in manual packaging, the separation work cannot be completed continuously and efficiently, and there are also high error rates
