Description

Technical Field

[0001] The utility model relates to the technical field of sewing equipment, in particular to a thread-releasing device with adjustable angle. Background Art

[0002] In the process of electrolytic aluminum production, the molten aluminum needs to be filtered first. At this time, liquid filter bags made of polypropylene, polyester and nylon are often used. Due to the large amount of filter bags used, factories often sew their own filter bags.

[0003] The prior art is to place the coils of the three materials on a pay-off device, which is tilted and placed next to a sewing machine, on which a thread closing member B (such as Fig. 9 As shown in the figure, the three materials are combined into one piece for sewing, the coil is aligned with the position of the thread joining piece, and the sewing machine pulls the thread to sew a filter bag. However, due to the large diameter and heavy weight of the coil, and there are many sewing machines, the coils are placed in different positions. Workers need to carry the pay-off device to make the coil aligned with the position of the thread joining piece. The process is cumbersome and labor-intensive. At the same time, the coils are not of standard size. Some coils are higher and some are thicker. The angle of the pay-off device cannot be adjusted. When coils of different sizes are placed on the pay-off device, the coils cannot be aligned with the position of the thread joining piece at a suitable angle. Some pay-off devices can only be placed at a position close to the sewing machine. During the thread drawing process, the coil will be pulled, affecting the pay-off and thus affecting the sewing progress. Utility Model Content
