Embodiment Construction

[0020] The oil supply mechanism at the looper seat in this sewing machine is applied to the keyhole sewing machine. The keyhole sewing machine includes the up and down movement mechanism of the needle bar, the needle swing mechanism and the thread take-up mechanism, the looper 4 on the looper seat and the actuating cam plate 2 Synchronized with the up and down movement of the sewing needle. During the movement, the support table 1 and the actuating cam plate 2 frequently move toward each other, which is prone to faults such as sintering; meanwhile, the looper 4 also needs a certain amount of lubrication. The mechanism can provide lubrication to the contact surface of the support platform 1 and the actuating cam plate 2 and the looper 4, and the oil guide structure is reasonably set, which is convenient for production and processing.

[0021] Such as figure 1 , figure 2 with image 3 As shown, the looper seat of the sewing machine includes a support platform 1 and a V-shape...

Abstract

The invention provides an oil supply mechanism of a curved needle seat in a sewing machine, which belongs to the technical field of machinery. The invention solves the problem that the traditional oil supply mechanism needs to process an oil guide structure at a curved needle seat and an actuating cam plate and can not supply oil to a curved needle. In the oil supply mechanism of the curved needle seat in the sewing machine, the curved needle seat comprises a support seat platform and an actuating cam plate, wherein the support seat platform and the actuating cam plate are mutually abutted together, and the actuating cam plate is articulated on the support seat platform by a connecting shaft; a curved needle hole capable of installing a curved needle is arranged on the support seat platform; an oil supply hole is arranged on the support seat platform; and an oil guide structure which can guide oil in the oil supply hole into the curved needle hole is arranged between the support seat platform and the actuating cam plate. The oil supply mechanism of the invention supplies oil to the contact surface of the support seat platform and the actuating cam plate and the curved needle, and the oil in the oil supply hole permeates into the contact surface of the support seat platform and the actuating cam plate by an oil guide structure and is supplied to the contact surface of the support seat platform and the actuating cam plate; meanwhile, the oil can also flow into the curved needle hole and is supplied to the curved needle.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a sewing machine, in particular to an oil supply mechanism at a looper seat in the sewing machine. Background technique [0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material to interweave or sew one or more layers of sewing materials. The stitches are neat, beautiful, flat and firm. Fast sewing and easy to use. In the keyhole sewing machine, the motor drives the main shaft to rotate, and drives the needle bar up and down movement mechanism, needle swing mechanism and thread take-up mechanism, and at the same time makes the looper on the looper seat and the actuating cam plate synchronize with the up and down movement of the sewing needle. Perform an action to create keyhole stitches on the finished fabric. And in the whole action process, because the actuating cam plate and the surface of the support plat...
