Technical Field

[0001] The utility model relates to the technical field of filter cloth production and processing equipment, in particular to a sewing device for filter cloth. Background Art

[0002] At present, the filter cloth is an important component inside the filter press. During the pressure filtration process of the filter cloth, first, the liquid in the mixed liquid is dialyzed out, and the solid particles that cannot pass through the filter cloth are intercepted on the filter cloth. In this way, the solid and liquid in the mixed liquid are effectively separated, achieving the purpose of solid-liquid separation. This is the core function of the filter cloth in the filter press and also the basic means for the filter press to achieve solid-liquid separation.

[0003] Currently, in some factories that cannot achieve fully automated production and processing, the cloth raw materials are first purchased externally, then the cloth raw materials are cut into specific shapes, and finally the cloth raw materials are sewn into filter cloth. Moreover, such sewing still requires workers to manually contact and cooperate with the sewing machine to position the cloth raw materials. Since the cloth raw materials are soft and the filter cloth is sewn by stacking multiple layers of cloth raw materials together, during the manual positioning and sewing process by workers, the sewing position is easily deformed due to the movement of the workers' hands, resulting in poor quality of the sewn filter cloth. Therefore, it is necessary to design a filter cloth sewing device that can accurately position the sewn cloth raw materials. Content of the Utility Model
