Description

A variable-diameter supporting shoe device and yarn unloading method for glass fiber yarn unloading

technical field

The application belongs to the technical field of glass fiber production automation, and in particular relates to a variable-diameter supporting tile device and a yarn unloading method for glass fiber unloading.

Background technique

At present, with the rise of energy and labor costs and the intensification of production competition, how to improve efficiency and reduce costs has become the focus of glass fiber enterprises, so production automation has become an inevitable trend. The yarn unloading manipulator is an indispensable equipment for the automatic glass fiber production line, and the supporting block is a necessary device for the yarn unloading manipulator, which is used for temporarily storing the yarn cake during the yarn unloading process. When the silk cake is unloaded from the wire drawing machine, the water content is about 10%, and it is easy to collapse and deform, which will affect the subsequent de-solution process. In order to reduce the deformation of the wire cake, it is necessary to increase the load-bearing area of the support tile. The support tile is generally an arc-shaped structure, so the inner diameter of the wire cake determines the diameter of the arc-shaped support tile.

The diameter of the arc-shaped support tile in the prior art is fixed and can only be adapted to a silk cake of one specification. In the actual production process, silk cakes of different specifications are produced on the same production line, so it is necessary to prepare curved supports of different diameters, which not only costs a lot, but also takes time and effort to replace supports of different sizes, which affects production efficiency. Under normal circumstances, due to the use of the yarn unloading robot, the weight of the yarn cake is relatively large, and the weight of a single yarn cake can reach 50kg, and the yarn cannot be unloaded manually. If a small-diameter support is used to unload a large-diameter silk cake, the inner circle of the silk cake and the force section of the support are very narrow, which will easily cause deformation of the silk cake, reduce the qualified rate of the product, and affect the use of the subsequent process.
