Embodiment 1

[0026] Embodiment 1: As shown in Figure 1-14, the oiling device for the sewing thread of the electric sewing flat car includes an upper cover 1, an oil inlet box 2, a rubber ring 3, sponges 4, 5, a wet thread box 6 and a magnet 7. The oil inlet box 2 is cylindrical, and its upper mouth is connected with the upper cover 1 by threads. Two small oil holes 11 are arranged at the bottom of the oil inlet box 2, and the center of the bottom of the oil inlet box 2 forms a protrusion 9 downwards. The bottom of the oil inlet box 2 is threadedly connected with the wet line box 6, and the joint between the two is sealed by a rubber ring 3. The upper surface of the wet line box 6 is in a concave shape, and the center forms a circular protrusion 10 upwards. The two layers of sponges 4 and 5 are ring-shaped, placed on the depression of the wet line box 6, the protrusion 9 of the oil inlet box 2 extends into the hollow of the ring protrusion 10, and the two are interference fit; the wet line ...

Abstract

The present invention belongs to the technical field of electric sewing flat-car fittings and relates to an oiling device for sewing thread of an electric sewing flat car, wherein, an oil inlet box is in bolt connection with an upper cover; the bottom of the oil inlet has a through hole, and the center of the bottom is downward convex; the lower part of the oil inlet box is in bolt connection with a thread humidifying box with a sealing ring at the joint; the upper surface of the thread humidifying box appears recessed and the center protrudes upward to form a circular bump; two circular cotton pads are positioned on the recess of the thread humidifying box; the convex part of the oil inlet box extends into the hollow part of the circular bump and forms interference fit; the upper margins of the thread humidifying box are molded into threading grooves; two threading grooves are in the same line; a thread passes through the threading grooves and between the two cotton pads; the bottom of the thread humidifying box appears concave and the bottom center protrudes downward to form a bump; a circular magnet is positioned in the bottom of the thread humidifying box. The oiling device of the present invention can supply oil uniformly for the thread of the electric sewing flat car, thereby preventing thread break in the process of high-speed sewing.

Description

【Technical field】 [0001] The invention belongs to the technical field of manufacturing electric sewing flat car accessories, in particular to a sewing thread refueling device for an electric sewing flat car. 【Background technique】 [0002] As we all know, China is a big country in garment production and processing. At present, the main equipment for garment processing and production is a high-speed electric sewing flat car. In the process of garment production and processing, due to the different types and qualities of garments, the requirements for sewing threads are also different. Some garments are required to be sewn with thick threads, while some garments are required to be sewn with thin threads. There is a problem when the electric sewing flat car is sewing clothes. Because the electric sewing flat car runs at a very fast speed during the sewing process, the pinhole of the electric sewing flat car is prone to heat up and the thread is broken, especially the thin thr...
