Technical Field
The patent relates to the technical field of textile machinery, in particular to a roller pressurization short circuit alarm device.
Background
The combing machine is a machine which removes short fibers in the spinning process, removes kinking particles (neps, wool particles, grass clippings, cocoon skins and the like) in the fibers, straightens and parallels the fibers and finally produces combing strips with uniform thickness. The roller, cylindrical rotary parts in the combing machine with feeding, drafting and outputting functions, etc. are widely used in drafting, carding, conveying and other mechanisms. When the pressure of the roller reaches a certain degree in the pressurizing process, a short circuit alarm protection mechanism needs to be started. The safety alarm mechanism of the existing roller pressurizing device is a combined spring closing and breaking short circuit alarm, and has the following problems: the spring is a fixed stroke, and the short circuit contact distance is inconvenient to adjust. Because the flexible piece spring is used for providing power for short circuit, when the short circuit device acts for a certain number of times and the spring reaches a certain fatigue limit, the short circuit device is scrapped immediately. The foreign matters such as batting are more in the textile machinery, and the short circuit mechanism is that open structure spring contact department is blockked up by the foreign matter easily, makes this safe short circuit mechanism inefficacy. The open short circuit mechanism can be accompanied with the appearance of electric spark at the moment of the action of the safety short circuit device, and certain potential safety hazards exist in a textile workshop.
