Technical Field:

[0001] The utility model relates to the technical field of sewing machines, in particular to an automatic lubrication system for a sewing machine. Background Art:

[0002] In the process of clothing production, the most commonly used tool is a sewing machine. Currently, most of them are electric sewing machines. During use, appropriate lubricating oil needs to be added regularly, which can effectively reduce friction, prevent rust, and thus extend the service life of the sewing machine.

[0003] Currently, the electric sewing machines on the market do not have an automatic oiling device. It entirely depends on the operator's usual experience to inject oil with a brush or an oil pot. This is not only time-consuming and laborious, but also the dripping lubricating oil cannot be recycled, resulting in waste and environmental pollution. It may also cause equipment damage due to untimely lubrication. Content of the Utility Model:

[0004] The purpose of the utility model is to provide an automatic lubrication system for a sewing machine to solve the problems raised in the above background art.

[0005] The utility model is implemented by the following technical solutions:

[0006] An automatic lubrication system for a sewing machine includes a sewing machine housing and components to be lubricated inside the housing; it also includes an automatic lubrication system, which includes a sub-oil tank, an oil storage chamber, an oil distribution chamber, a guide rod, an electromagnet, a sealing plug, a through groove, an oil discharge chamber, and an oil guide pipe; the sub-oil tank is installed inside the top of the housing, a middle part of the sub-oil tank is provided with an oil storage chamber, oil distribution chambers are symmetrically arranged on both sides of the oil storage chamber inside the sub-oil tank, a guide rod is vertically fixed inside the oil distribution chamber, the top end of the guide rod is fixed with an electromagnet, the electromagnet is connected in parallel with the positive and negative ends of the sewing machine start button through a circuit, a sealing plug is slidably sleeved on the guide rod, the oil distribution chamber is communicated with the oil discharge chamber below it through a through groove, one end of the oil discharge chamber is connected with one end of the oil guide pipe, and the other end of the oil guide pipe is located at the lubricating part of the component to be lubricated.

[0007] Preferably, a threaded through hole is opened at the top of the oil storage chamber, and a sealing cover is threadedly connected inside the threaded through hole.

[0008] Preferably, a frustum is fixed at the bottom of the guide rod, a through hole adapted to the guide rod is opened inside the sealing plug to enable the sealing plug to slide on the guide rod, and a limiting groove adapted to the frustum is opened on the lower surface of the sealing plug.

[0009] Preferably, the through groove is in a "funnel" shape, and the sealing plug is movably placed inside the through groove to open or close the through groove.

[0010] Preferably, a metal plate is fixed on the upper surface of the sealing plug, and after the electromagnet is energized, the metal plate slides upward and is attracted to it.

[0011] Advantages of the present utility model: By using the magnetic force generated by the electromagnet, after the electric sewing machine is powered on and operates, the sealing plug in the through groove adsorbs and slides upward along the guide rod, so that the through groove is opened, allowing the lubricating oil to flow into the oil drainage chamber through the through groove, and the lubricating oil flows into the lubricating part of the part to be lubricated along the oil guide pipe for automatic oil replenishment, finally completing the process of automatic oil replenishment. The operation is simple, and only the lubricating oil needs to be regularly filled into the oil storage chamber. Brief Description of the Drawings:

Specific Embodiments:

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-5 , the present utility model provides a technical solution for an automatic lubrication system of a sewing machine:

[0020] An automatic lubrication system for a sewing machine, comprising a sewing machine housing 1 and components to be lubricated inside the housing 1; it further includes an automatic lubrication system, which includes a sub-oil tank 2, an oil storage chamber 3, an oil distribution chamber 4, a guide rod 5, an electromagnet 6, a sealing plug 7, a through groove 8, an oil discharge chamber 9 and an oil guide pipe 10;

[0021] The sub-oil tank 2 is installed inside the top of the housing 1. In the middle of the sub-oil tank 2, there is an oil storage chamber 3 for storing lubricating oil. On both sides of the oil storage chamber 3 in the sub-oil tank 2, there are symmetrically arranged oil distribution chambers 4. Vertically fixed in the oil distribution chamber 4 is a guide rod 5. At the bottom of the guide rod 5, there is a frustum 5.1 fixed. At the top of the guide rod 5, there is an electromagnet 6. The electromagnet 6 is connected in parallel with the positive and negative ends of the sewing machine start button through a circuit. A sealing plug 7 is slidably sleeved on the guide rod 5. A through hole 7.1 adapted to the guide rod 5 is opened in the sealing plug 7, enabling the sealing plug 7 to slide on the guide rod 5. A limiting groove 7.2 adapted to the frustum 5.1 is opened on the lower surface of the sealing plug 7. The oil distribution chamber 4 communicates with the oil discharge chamber 9 below it through the through groove 8. One end of the oil discharge chamber 9 is connected to one end of the oil guide pipe 10. The other end of the oil guide pipe 10 is located at the lubrication part of the component to be lubricated, and the length of the oil guide pipe 10 is not limited.

[0022] A threaded through hole 3.1 is opened at the top of the oil storage chamber 3. A sealing cover 3.2 is threadedly connected in the threaded through hole 3.1. By opening the sealing cover 3.2, lubricating oil can be filled into the oil storage chamber 3.

[0023] The through groove 8 is in the shape of a "funnel". A metal plate 7.3 is fixed on the upper surface of the sealing plug 7. After the electromagnet 6 is energized, the metal plate 7.3 slides upward and is attracted to it, enabling the sealing plug 7 to be movably placed in the through groove 8 to open or close the through groove 8.

[0024] The working principle is as follows: When the electric sewing machine turns on the start button, the electric sewing machine starts to be powered on and prepares for work. At the same time, after the two electromagnets 6 are energized, electromagnetic force will be generated, adsorbing and sliding the sealing plug 7 in the through groove 8 upward along the guide rod 5, opening the through groove 8, allowing the lubricating oil to flow into the oil discharge chamber 9 through the through groove 8, and the lubricating oil flows into the lubrication part of the component to be lubricated along the oil guide pipe 10 for automatic oil replenishment;

[0025] When the electric sewing machine turns off the start button, the electric sewing machine is powered off and stops working. At the same time, after the two electromagnets 6 are powered off, the electromagnetic force is lost, causing the sealing plug 7 to fall into the through groove 8 along the guide rod 5, closing the through groove 8 and stopping the lubricating oil from flowing into the oil discharge chamber 9, stopping the oil replenishment process.

[0026] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
