[0002] The heel grinder automatic device for sewing machines is an integrated automated auxiliary device. It is primarily used for automatic positioning and grinding of the heel during the sewing process of products such as footwear and bags. Through its precise mechanical structure and control system, the device automatically captures, positions, sews, and performs subsequent processing of the heel grinder, significantly reducing operator workload and improving production efficiency and product quality.
[0003] The docking process between the heel mold automatic device and the sewing machine is typically carefully designed using advanced fixed-point connection technology, designed to achieve highly precise docking positioning to ensure a smooth and efficient production process. However, in actual production environments, due to a variety of factors, including but not limited to subtle dimensional differences between the heel mold and sewing machine components, the effects of thermal expansion and contraction of materials, and minor wear of mechanical components after long-term use, these subtle variations often lead to unavoidable minor errors between the docking points, resulting in ineffective docking.

[0019] See also Figure 1-4 The utility model provides the following technical solutions: an automatic device for a heel mold of a sewing machine, comprising an automatic machine 1, one end of the automatic machine 1 is connected to a heel mold 2, an end of the automatic machine 1 away from the heel mold 2 is installed with a mounting member 3, and a side ear 4 is installed on both sides of the mounting member 3;
[0020] During use, the heel material of the shoe is clamped on the heel mold 2 , and the sewing machine sews the heel material of the shoe along the reserved track on the heel mold 2 when working.
[0021] A pad 5 is bonded to the bottom of the side ear 4 , and a through hole 6 is formed through the surface of the side ear 4 .
[0022] Preferably, a side strip 301 is fixedly mounted on each of the outer walls of the mounting member 3, a bottom strip 302 is fixedly mounted on the bottom of the side strip 301, and an end plate 303 is bonded to the surfaces of each end of the mounting member 3.
