Description

Technical Field

[0001] The utility model relates to the technical field of shoe processing, in particular to a shoe leather scraping device for shoe processing. Background Art

[0002] During the shoemaking process, the leather joints of the upper components need to be thinned before splicing to facilitate subsequent splicing. However, when processing upper components of varying thicknesses, the existing leather-scraping machines are complex to adjust the thickness of the leather, and the thickness cannot be precisely controlled, resulting in reduced leather-scraping efficiency.

[0003] A Chinese patent discloses a shoe upper scraping machine (authorization announcement number CN214509790U). This patented technology arranges connecting blocks with waist-shaped through holes on both sides of a pressure block above the scraping wheel. The connecting blocks are connected to a suspension rod, and a positioning rod fixed to the side of the suspension rod passes horizontally through the waist-shaped through holes. When it is necessary to process shoe upper parts of different thicknesses, the connecting blocks can be moved up and down along the side of the suspension rod, making it easy to adjust the distance between the pressure block and the scraping wheel. At the same time, with the help of scale lines on the side of the suspension rod, the distance the pressure block moves up and down can be accurately adjusted, thereby achieving precise control of the scraping thickness of the shoe upper parts.

[0004] However, it has certain disadvantages: the height of the pressing block is adjusted by rotating the bolt to press the connecting block onto the boom. This adjustment method is relatively troublesome, and since the shoe surface will vibrate when passing between the pressing block and the shovel wheel, the vibration will be transmitted to the bolt surface. Over time, the bolt will loosen, resulting in a change in the height of the pressing block after adjustment. Utility Model Content
