Description

Technical Field

[0001] This utility model relates to the field of shoe edge polishing technology, and in particular to a shoe edge polishing device with adjustable position. Background Technology

[0002] In the footwear manufacturing and repair industry, edge polishing is one of the key processes affecting the quality of finished products. As the area where the shoe body directly contacts the ground, the flatness, smoothness and edge consistency of the shoe edge not only affect the aesthetic appearance of the shoe, but also directly affect the comfort and durability of wearing. However, traditional edge polishing processes have long faced pain points such as low automation, reliance on manual experience, and insufficient processing precision, resulting in limited production efficiency and large fluctuations in product yield. With the rapid development of intelligent manufacturing technology, the industry has an increasingly urgent need for high-precision and highly adaptable automated polishing equipment. The position-adjustable edge polishing device is an innovative solution proposed to solve this technical bottleneck. A women's shoe edge polishing device disclosed in CN216939848U includes an edge polisher. The edge polisher comprises a support platform and an L-shaped bracket mounted on the support platform. A drive motor is mounted on the L-shaped bracket, and a transmission shaft is mounted on the power output end of the drive motor. A connecting column is fitted onto the outer end of the transmission shaft, and a polishing head is connected to the upper end of the connecting column. A dust extraction and dirt reduction mechanism is installed in the middle of the connecting column. The dust extraction and dirt reduction mechanism consists of a collar, a funnel-shaped air guide cover, an air supply pipe, a sprayer, a collection box, and an air pump. This invention provides a dust extraction and dirt reduction mechanism at the polishing head position of the shoe edge polishing device. This mechanism can extract dirt generated on the shoe edge during the polishing process and guide it into a dedicated collection box. A sprayer installed on the top of the collection box can reduce dust in the air. The reduced dirt is then guided into the collection box, thereby achieving the purpose of dust reduction.

[0003] When using the existing technology, the grinding position is inconvenient to adjust when using a grinding head to grind the shoe edge. The fixed grinding head is difficult to accurately match the shoe edge contour, which may lead to over-grinding in some areas (such as the heel or toe arc surface), forming a depression or thin edge, while other areas are under-grinded, leaving burrs or glue residue, requiring rework. This reduces the precision and quality of shoe edge grinding. Therefore, corresponding improvements are needed. Utility Model Content
