Coarse spinner bobbin supporting guiding device

Abstract

The invention provides a coarse spinner bobbin supporting guiding device. The coarse spinner bobbin supporting guiding device comprises a gear shaft, a bobbin, a lower supporting module, a bobbin shaft and an upper supporting module, wherein the bobbin shaft is fixed onto the upper end surface of the gear shaft; the bobbin is arranged on the annular side surface of the bobbin shaft; the bobbin isconnected with the gear shaft and the bobbin shaft through the lower supporting module; the upper supporting module is mounted on the upper annular side surface of the bobbin shaft and connected withthe internal upper end of the bobbin; the lower supporting module is composed of connecting flanges, a fixing ring, a clamping table, a clamping pressure plate, an electric extending column I, a moving table, an electric extending column II, a connecting ring I and a connecting ring II; the upper supporting module comprises a connecting tube, a supporting guiding block, a connecting rod, a spring,a groove, a fixing sleeve and a hanging member. Compared with the prior art, the coarse spinner bobbin supporting guiding device has the advantages of achieving the aim of simplifying mounting operation steps and improving the connecting stability, and being good in adaptability and simple in structure.

Description

technical field [0001] The invention relates to a supporting and guiding device for bobbins of a roving frame, which belongs to the field of textile equipment. Background technique [0002] The roving frame is the pre-spinning equipment of the textile enterprise. Its main function is to improve the parallel straightness and separation of the sliver by drafting and carding the sliver supplied by the drawing frame, and to improve the strength and compactness of the sliver by twisting. Finally, the drafted and twisted sliver is spun into roving, which is spun into spun yarn for spinning frame. The bobbin in the roving frame is installed on the bobbin gear of the lower rib, and the bobbin gear is provided with a positioning pin. The bobbin gear drives the bobbin to rotate through the positioning pin, and the roller is output through the speed difference between the bobbin gear and the flyer. The yarn is wound onto the empty bobbin to complete the process of spinning roving. In...

Problems solved by technology

[0003] In the new automatic doffing roving frame, the bobbin not only needs to reciprocate up and down, but also needs to reciprocate horizontally after each doffing. During the start and stop of the movement, the bobbin is easy to move due to inertia. Dumping occurs, which directly leads to the failure of automatic doffing

In addition, during traditional doffing, the bobbins are manually filled and empty, and the bobbin guidance is relatively unimportant. However, in the automatic doffing roving frame, the full yarn is completely automatically filled and empty. If the original structure is used, it will be very easy. The phenomenon of bobbin jacking is easy to occur, so a roving frame bobbin support and guide device is needed to solve the above problems
