Automatic bobbin winder cone yarn contact pressure control device

Abstract

The invention provides an automatic bobbin winder cone yarn contact pressure control device which comprises a single spindle machine shell, a groove drum, a support arm, a support arm connecting rod and double cylinders. The control device is characterized in that a gear is arranged at one end of a support arm rotating shaft connected with the support arm connecting rod, a transmission wheel meshed with the gear is arranged on the inner side of the single spindle machine shell and connected with the single spindle machine shell through a rotating shaft, the lower end of a transmission swing rod is fixed on the rotating shaft of the transmission wheel, the upper end of the transmission swing rod is connected with the upper end of a spring, and the lower end of the spring is connected with the lower end of an adjusting swing rod. The action force of the spring on the support arm is opposite to that of double cylinders at the beginning and gradually transformed to be consistent with that of the double cylinders along with increase of the diameter of a cone yarn in the winding process of a bobbin winder, so that the contact pressure between the cone yarn and the groove drum is basically kept constant. Undesirable effects such as yarn overlapping are decreased, and the quality of the cone yarn is improved.

Description

Technical field [0001] The invention belongs to the technical field of textile equipment manufacturing, and relates to the improvement of an automatic winder, in particular to a package yarn contact pressure control device for an automatic winder. Background technique [0002] During the winding process of the winding machine, as the diameter of the cone increases, the contact pressure between the cone and the grooved cone will change. Controlling the contact pressure of the cone to keep it basically the same is an important measure to ensure the quality of the cone. [0003] At present, there are mainly the following ways to balance the contact pressure of the yarn of the main brand winders in the world: [0004] Schlafhorst’s 338 and AC5 brand winders have two control methods: one uses an electromechanical arm control system, which uses a stepper motor and a two-layer gear set to control the contact pressure. The gear set is connected to the support arm by a spring connection, and...

Problems solved by technology

[0007] In order to solve the above-mentioned problems and deficiencies in the prior art, the present invention provides an automatic winder bobbin yarn contact pressure control device, which has a simple structure, low cost, convenient installation and debugging, and can be installed with the bobbin during the winding process of the winder. The larger the diameter, the automatic adjustment of the contact pressure between the bobbin and the grooved bobbin, so that the contact pressure is basically consistent, thereby reducing the unfavorable phenomena such as overlapping yarns and improving the quality of the bobbin
