[0002] Leather edge oiling machine plays a vital role in the leather products processing industry. It is mainly used to oil the edges of leather to enhance its beauty and durability. During the use of the leather edge oiling machine, the positioning fixture module is a key component to ensure processing accuracy and efficiency. The main function of this module is to stably fix the leather during the oil edge treatment to prevent it from moving or deforming, thereby ensuring the quality and consistency of the oil edge treatment.

[0003] With the booming development of the leather products market and the increasing diversification of consumer demand, the performance requirements for leather edge oiling machines are becoming increasingly stringent. Traditional positioning fixture modules are unable to cope with these high standards. Problems such as inaccurate positioning and loose fixation occur frequently, which seriously affect the effect of edge oiling and may even cause damage to the leather. More importantly, these fixtures often lack sufficient flexibility and adaptability and cannot effectively cope with leather of different sizes and thicknesses. This limits the application scope and processing efficiency of leather edge oiling machines to a certain extent.
