Problems solved by technology

The winding speed is calculated from the rotation speed of the pressure roller, but the pressure roller is in passive contact with the collet shaft, there is a slip, and its line speed is not the real winding speed
Moreover, when the threading is switched, the pressure roller and the bobbin chuck shaft are separated, and the speed of the pressure roller will naturally decrease, which has a bad influence on the winding of the bottom layer of the new silk cake, and when unwinding Prone to breakage and stripping

Embodiment Construction

[0018] In the figure, the tow 2 reciprocates alternately along the forming plate 3 through the fork 4 driven by the gear box 1, and the bobbin is installed on the chuck shaft 6, and the chemical fiber filament is wound into a cylindrical shape on the bobbin of the winding head. rolls.

[0019] exist image 3 Among them, the pressure roller 5 is supported by a bearing 7, and the motor 10 is connected with one end of the pressure roller 5 through a coupling 9. Because the moment of inertia of the roller body changes from hollow to solid, the pressure roller is now driven by an asynchronous high-speed motor, changing from passive to active. After the automatic switching of the winding head, the speed of the pressure roller 5 will not be affected by the detachment from the chuck shaft, which will have an ideal contact pressure for the winding of the bottom silk of the new silk cake, and the silk during the winding cycle The circles are closely arranged, and the degree of closene...

Abstract

The invention relates to a chemical filament winding device, in particular to a small-diameter press roll for a chemical filament winding head. The press roll body is a solid roll body; shaft heads at two ends of the press roll are supported by bearings; one end of a press roll shaft is connected with a motor through a coupling; a speed measuring wheel is arranged between the bearings and the coupling; the press roll body is equipped with a balancing hole; and the length C of a filament bundle between a forming board and a bobbin chuck shaft is less than A, and a wrap angle D of the filament bundle on the press roll is greater than a wrap angle B. By utilizing the press roll device for the chemical filament winding head, winding speed of the chemical filament winding head is increased;d meanwhile, forming and unwinding properties of a spinning cake are improved.

Description

Technical field [0001] The invention relates to a winding device for chemical fiber filaments, in particular to a small-diameter chemical fiber filament winding head pressure roller. Background technique [0002] The chemical fiber filament is wound into a cylindrical package on the winding head. During the winding process, the pressure roller is always in contact with the silk cake on the shaft of the bobbin chuck with the set contact pressure, and the pressure roller is driven by the friction of the bobbin chuck, which is a passive type. At present, the pressure roller is generally set as a large-diameter hollow roller. The reason is that the hollow roller has the advantage of small moment of inertia and is suitable for passive type. But its advantages also make its disadvantages. From the perspective of machining, it is necessary to increase the diameter of the pressure roller to process the inner hole. It is necessary to ensure the coaxiality of the inner hole and the ...
