Description

Technical Field

[0001] The utility model relates to a sewing machine edge retainer with an automatic lifting function. Background Art

[0002] The patent number is 201720643888.X, and its name is A sewing machine edger installation structure. It discloses an edger that is integrally fixedly connected to the presser foot rod of the sewing machine head, and can be raised and lowered with the lifting of the presser foot rod to achieve an automatic lifting function. However, this edger can only be used for small edgers with smaller volumes, and its adjustable space is very small, which greatly hinders the operation of the sewing machine and has poor versatility. When a larger edger is needed, the power that the presser foot rod itself can provide is not large, and the large edger cannot be directly fixed on the presser foot rod for use. Therefore, the existing large edgers are all fixedly installed on the sewing machine frame, and cannot be raised and lowered with the lifting of the presser foot rod to achieve an automatic lifting function. Summary of the invention

[0003] The utility model provides a sewing machine edge device with an automatic lifting function, which has the advantages of a large adjustable range and strong versatility.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions: a sewing machine side leaner with automatic lifting function, comprising a fixed base, a side leaning plate and a rotating shaft, the fixed base is fixed on the sewing machine frame, the side leaning plate is connected to the fixed base through the rotating shaft, the side leaning plate comprises a foot leaning, an adjusting device and a connecting plate, the foot leaning is connected to the connecting plate through the adjusting device, and the up, down, left and right position adjustment can be achieved through the adjusting device, the connecting plate is fixed on the rotating shaft and flips up and down with the rotating shaft, a lifting device is provided under the connecting plate, the lifting device comprises a connecting seat and an adjusting screw, one end of the connecting seat is fixed to the sewing machine presser foot rod together with the sewing machine presser foot plate, the other end of the connecting seat extends to the bottom of the connecting plate, and the end of the connecting seat located under the connecting plate is provided with a threaded hole, the threaded hole is threadedly matched with the adjusting screw, and the screw abuts against the lower surface of the connecting plate.

[0005] The beneficial effects of the utility model are as follows: a lifting device is arranged below the connecting plate of the edge device, which is fixed on the presser foot rod through a connecting seat in the lifting device and is lifted and lowered together with the presser foot rod, and then the connecting plate is driven to lift and lower through an adjusting screw abutting against the lower surface of the connecting plate, thereby realizing an automatic lifting function. When sewing articles of different thicknesses, the presser foot plate and the edge device are lifted and lowered at the same time to press the two sides of the article, and when the sewing article is replaced, the edge device and the presser foot plate are automatically lifted while the presser foot rod is lifted. The adjusting screw is arranged to cooperate with the threaded hole, and the specific height of the lifting connecting plate can be realized by adjusting the screw to adapt the lifting height of the presser foot plate, so as to achieve a more appropriate pressing of the two sides of the sewn article.

[0006] Furthermore, the axis of the threaded hole of the connecting seat at one end below the connecting plate is set in the horizontal direction, and the adjusting screw is adjusted forward and backward in the horizontal direction to abut against the connecting plate. The axis of the threaded hole and the adjustment direction of the adjusting screw are set in the horizontal direction. This can leave more space under the edge device to avoid scratching with the sewn part of the object, while also leaving more available space for the sewing machine work surface.

[0007] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. BRIEF DESCRIPTION OF THE DRAWINGS
