4 results about "Razor Blade" patented technology

This invention relates to the field of razor devices, and more particularly to a razor blade marking device, comprising a base plate, on which feeding devices are symmetrically arranged on both sides. Each feeding device includes a lead screw and a slide rod mounted on the base plate. The lead screw is driven to rotate by a feeding motor. The feeding device also includes a slide plate, through which the slide rod passes and is slidably connected. A threaded tube is fixed to the slide plate, through which the lead screw passes and is threadedly connected. A positioning rod for holding the blade is also provided on the slide plate. A support rod for cooperating with the blade is fixed above the base plate, passing through and slidably connected to the slide plate. A rotary motor is also fixed to the base plate, with a rotating seat fixed to the output end of the rotary motor. A laser marking head is fixed to the rotating seat. This device eliminates the need to individually place each blade, greatly improving the marking efficiency of the blades.

The application discloses a shaving razor linear motor adaptive control method and system, collects control input data and response data, analyzes envelope attenuation end section associated characteristics, and outputs early warning identification of drift; overshoot phase difference detection is carried out on input and output data, combined with matching of sub-working condition spectrum library to establish error checking matrix; gain rule groups are formed by implementing early phase section priority gain distribution on the error checking matrix according to the early warning identification of drift, and abnormal characteristic points are positioned by multi-working condition phase time difference analysis and deviation overrun judgment; an excitation sequence is obtained by activating the gain rule groups, an amplitude stability index is output by pseudo-convergent oscillation detection and cross-load reverse correlation strength evaluation; a control characteristic atlas is constructed by combining the amplitude stability index and excitation sequence deviation interval characteristics, adaptive control parameters are output by parameter deviation mapping to complete linear motor control parameter configuration, and adaptive configuration of control parameters of the linear motor under variable working conditions is realized.

To provide a hair cut unit of a reciprocation type electric shaver.SOLUTION: A hair cut unit of a reciprocation type electric shaver includes an outer blade, an inner blade, a support, and a holder. The outer blade includes an outer blade arc-shaped wall and two opposite outer blade long walls, wherein the support supports the inner blade, and the holder includes two opposite holding walls. The outer blade long walls are provided with follow holes, at least the one support penetrates through the follow holes, and the outer blade long walls are movable along a support penetrating through the follow holes. When the cut unit receives non-uniform pressure from skin, the outer blade arc-shaped walls follow the moving outer blade long walls, can include the inner blade without being deformed, and accordingly can maintain high hair cut efficiency even at the time of actual use.SELECTED DRAWING: Figure 5
