Problems solved by technology
When automatic backstitching is performed during the operation of the lockstitch sewing machine, there is a problem that the iron core of the backstitching electromagnet collides with the electromagnet body when it is attracted and released, and the sound is louder, which increases the noise of the sewing machine
The sewing machine is noisy, which directly reduces the quality of the sewing machine
However, there is no effective way to reduce the sound of reverse stitching on the premise of ensuring the accuracy of reverse stitching on the current lockstitch sewing machine

Embodiment Construction
[0021] The present invention will be further described below with specific embodiment, see figure 1 -2:
[0022] The oil buffer reverse stitching electromagnet mechanism includes a bottom plate 1 and an oil box 2 arranged under the bottom plate 1, a lubricating oil 3 is arranged in the oil box 2, an electromagnet 4 is arranged on the bottom plane of the bottom plate 1, and an electromagnet 4 Soaked in lubricating oil 3, the head of the electromagnet iron core 5 is located at the end away from the swing plate base 6, the head of the iron core 5 is hinged with the swing plate base 6 through the connecting mechanism, and the swing plate base 6 passes through the left pin 7 and the right Pin 8 is installed on the base plate 1, and the action of electromagnet iron core 5 drives the link mechanism action and then drives the swing plate seat 6 action.
[0023] Above-mentioned link mechanism is: comprise fork 9, and one end of fork 9 is hinged with the head of electromagnet iron core...

The invention belongs to the technical field of a sewing machine, and particularly relates to an oil buffer backstitch electromagnet mechanism. The oil buffer backstitch electromagnet mechanism comprises a base plate and an oil box arranged under the base plate, wherein the oil box is internally provided with lubricating oil, an electromagnet is arranged on the bottom plane of the base plate, the electromagnet is dipped into the lubricating oil, the head of an electromagnet core is arranged at one end which is far away from a swinging plate base, the head of the electromagnet core is hinged with the swinging plate base through a connecting mechanism, the swinging plate base is arranged onto the base plate by a left pin and a right pin, and the electromagnet core runs to enable a connecting rod mechanism to run so as to enable the swinging plate base to run. After the oil buffer backstitch electromagnet mechanism is used, the electromagnet is dipped into the lubricating oil; when the electromagnet core is sucked, the electromagnet body is internally filled with lubricating oil; the lubricating oil in the electromagnet body can be extruded when the electromagnet core is sucked, so that the oil buffer backstitch electromagnet mechanism has a certain buffer effect; when the electromagnet is powered off to stop running, the backstitch mechanism can be rebounded, the electromagnet core can be extracted out of the electromagnet body, and the electromagnet body internally can forms the vacuum to form a reactive force to the extraction of the electromagnet core, so that the oil buffer backstitch electromagnet mechanism plays a part in buffering and noise reducing.
Description
Technical field: [0001] The invention belongs to the technical field of sewing machines, in particular to an oil buffer reverse sewing electromagnet mechanism. Background technique: [0002] At present, the automatic reverse sewing action on the lockstitch sewing machine is driven by an electromagnet. When the lockstitch sewing machine is performing automatic reverse sewing, there is a problem that the iron core of the reverse sewing electromagnet collides with the electromagnet body when it is attracted and released, and the sound is louder, which increases the noise of the sewing machine. The sewing machine is noisy, which directly reduces the quality of the sewing machine. However, there is no effective way to reduce the sound of back stitching under the premise of ensuring the accuracy of back stitching on the current lockstitch sewing machine. Invention content: [0003] The purpose of the present invention is to provide a kind of electromagnet soaked in lubricating...
