A brush lifting mechanism for a flat knitting machine
ActiveCN224280666UImprove mechanical propertiesGuaranteed stabilityWeft knittingGear driveGear wheel
This utility model discloses a brush lifting mechanism for a flat knitting machine, including a fixed frame, a brush drive motor mounted on the fixed frame, and a circumferential lifting brush mechanism. The circumferential lifting brush mechanism includes a lifting plate, a brush clamp located at the lower end of the lifting plate, transmission gears arranged along both sides of the fixed frame, and a lifting gear located at the upper end of the transmission gears. A drive gear is mounted on the output shaft of the brush drive motor, which passes through the fixed frame and is connected to the transmission gears via the drive gears. A rotating block extends from the lifting gear. When the output shaft rotates, it drives the drive gears and transmission gears to sequentially transmit power to the lifting gear. The lifting gear, through the rotating block, drives the lifting plate to move circumferentially. This utility model has a reasonable structural design. By setting up a circumferential lifting brush mechanism, the lifting plate can achieve circumferential lifting, which greatly improves the knitting adaptability and knitting quality of the flat knitting machine compared to traditional brush lifting methods.

A pencil sharpener blade assembly and a pencil sharpener
PendingCN122300109AEliminate local stress concentrationImprove reliabilityClassical mechanicsStructural engineering
This invention relates to a pencil sharpener blade assembly and a pencil sharpener, specifically for stationery. The pencil sharpener blade assembly includes a blade holder body, a blade, a screw, and a side clamping component. One side of the blade is fitted with the blade holder body, and the other side is fitted with the side clamping component. The screw is offset from the blade and connects the side clamping component and the blade holder body, ensuring that the side clamping component evenly presses the blade. The advantages of this invention are: it avoids the screw directly penetrating the blade, fundamentally eliminating the localized stress concentration at the mounting hole caused by the screw penetrating the mounting hole; the side clamping component is fitted and pressed tightly against the entire side of the blade, applying uniform pressure to the blade and preventing problems such as loosening, cracking, and breakage caused by the reverse force of pencil cutting, significantly improving the reliability of blade fixation.
