Problems solved by technology

In this way, it is very troublesome to achieve a very precise level of manual oil supply. Moreover, when the oil supply is insufficient or even forgotten, the lubrication of the sliding surface will be poor, and there will be problems such as wear and sintering.
Conversely, when the oil supply is excessive, the excess lubricating oil will drip from the sliding surface, causing the problem of staining the processing cloth

Embodiment Construction

[0028] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] The oil supply device for supplying oil to the looper seat of the present invention can pass through the second oil line in the supply pipe connected to the lubricating oil tank provided in the bed base of the buttonhole sewing machine and the first oil line in contact with the second oil line. thread, supply lubricating oil to the sliding surface of the cam plate for operating the spreader of the looper base.

[0030] As shown in Fig. 1 and Fig. 2, the buttonhole sewing machine 1 has: a rectangular box-shaped floor base 2 with an open upper part, a bottom plate part 3 mounted on the open part of the bottom plate seat 2 in an embedded form, and a bottom plate part 3 standing on the bottom plate part 3. The post 4 at the rear and the casing 5 extending forward from the upper part of the post 4, and the buttonhole sewing machine 1 is mount...

Abstract

An oil supply device, the deposited oil in the grease-box is filtered to the second oil line in the supplying pipe and guided to the loopier foundation, and is moved to the first oil line which contacts in the circumference and rotates on the loopier foundation, the oil supply device also supply oil to a sliding plane that slides on the support platform of a support plate actuation cam plate which contacts the front section of the first oil line, thereby, oil can be supplied to the sliding plane of the support plate actuation cam plate that swings at high speed stably, the abrasion of the sliding plane can be reduced, sinter can be avoided, the durability of a loopier foundation of the sartorial can be improved.

Description

(1) Technical field [0001] The present invention relates to an oil supply device for supplying oil to a looper seat of a sewing machine, in particular to an oil supply device that slides and swings between a support member having a pair of loopers and a support plate and the longitudinal wall of the looper seat Lubricating device for stably supplying oil to the sliding surface of the cam plate for operating the spreader. (2) Background technology [0002] In the keyhole sewing machine, the main shaft is driven by the sewing machine motor to rotate, and the rotation of the main shaft is transmitted to the needle bar up and down movement mechanism, the needle pendulum mechanism and the thread take-up mechanism. The needle on the rod moves up and down while swinging from side to side. And, the thread take-up lever is swung by the action of the thread take-up mechanism, and at the same time, the rotation of the main shaft is transmitted to a pair of left and right loopers arran...
