Description

Technical Field

[0001] This utility model belongs to the field of sewing machine lubrication technology, specifically relating to an oil supply mechanism for a sewing machine. Background Technology

[0002] Since its invention in the early 19th century, the sewing machine has undergone a development process from manual operation to mechanization and automation. Its technology has been constantly innovated, from the initial straight sewing to multi-functional sewing. Its application scenarios have also expanded from home mending to multiple fields such as garment manufacturing, leather processing, and home decoration, making it an indispensable piece of equipment in modern industry and daily life.

[0003] In the existing sewing machine oil supply mechanism, the force generated by the rotation of the main shaft during the operation of the sewing machine is usually ignored. The rotational power of the main shaft is not converted into the power source of the lubrication mechanism, resulting in low lubrication efficiency. It often requires additional energy or manual operation to maintain lubrication. Therefore, a new type of sewing machine oil supply mechanism has emerged. Utility Model Content

[0004] The purpose of this invention is to provide an oil supply mechanism for a sewing machine, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An oil supply mechanism for a sewing machine includes,

[0007] The assembly includes a mounting base, a sewing machine housing fixedly mounted on the surface of the mounting base, a sewing machine spindle movably mounted inside the sewing machine housing, a transmission gear sleeved on the outer surface of the sewing machine spindle, and an oil supply assembly disposed inside the sewing machine housing.

[0008] As a preferred embodiment of this utility model, the oil supply assembly includes an oil extraction component and an auxiliary component disposed at the bottom of the mounting base for use in conjunction with the oil extraction component.

[0009] As a preferred embodiment of this utility model, the oil extraction component includes a fixed shell fixedly installed in the inner cavity of the sewing machine housing, an oil inlet cavity disposed in the inner cavity of the fixed shell, and a main shaft plate mounted on the inner wall of the oil inlet cavity via a bearing.

[0010] As a preferred embodiment of this utility model, a secondary shaft plate is movably connected to the side wall of the main shaft plate, and a helical gear is fixedly installed on the side wall of the main shaft plate.

[0011] As a preferred embodiment of the present invention, the auxiliary component includes a connecting pipe communicating with the side wall of the fixed shell, and a nozzle communicating with the side wall of the connecting pipe.

[0012] As a preferred embodiment of this utility model, the auxiliary components further include an oil tank fixedly installed at the bottom of the mounting base, an oil suction box fixedly connected to the inner wall of the oil tank, and an oil extraction pipe connected to the side wall of the oil suction box.

[0013] In a preferred embodiment of this utility model, the transmission gear meshes with the helical gear, and the end of the oil extraction pipe is connected to the bottom of the fixed housing.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: through the cooperation between the oil extraction component and the auxiliary component, a highly efficient lubrication process is completed. The meshing of the transmission gear and the helical gear enables the rotation of the sewing machine spindle to drive the oil extraction component, which then draws the lubricating oil in the oil tank into the fixed housing through the oil extraction pipe, and then sprays it evenly onto the main shaft plate and the auxiliary shaft plate through the nozzle, realizing automatic lubrication of the sewing machine interior. This not only improves lubrication efficiency but also extends the service life of the equipment, while reducing maintenance costs and operational complexity. Attached Figure Description

Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0024] Example

[0025] Reference Figures 1-4 This is an embodiment of the present invention, which provides an oil supply mechanism for a sewing machine, comprising:

[0026] Mounting base 101, sewing machine housing 102 fixedly mounted on the surface of mounting base 101, sewing machine spindle 103 movably mounted in the inner cavity of sewing machine housing 102, transmission gear 104 sleeved on the outer surface of sewing machine spindle 103, and oil supply assembly 105 disposed in the inner cavity of sewing machine housing 102.

[0027] Specifically, the transmission gear 104 is mounted on the sewing machine spindle 103, which can drive the operation of the device through the operation of the sewing machine, thereby reducing energy consumption.

[0028] The oil supply assembly 105 includes an oil extraction component 105a and an auxiliary component 105b disposed at the bottom of the mounting base 101 for use with the oil extraction component 105a. The oil extraction component 105a includes a fixed shell 105a-1 fixedly installed in the inner cavity of the sewing machine housing 102, an oil inlet chamber 105a-2 disposed in the inner cavity of the fixed shell 105a-1, and a main shaft plate 105a-3 mounted on the inner wall of the oil inlet chamber 105a-2 by bearings. The oil extraction component 105a also includes a secondary shaft plate 105a-4 movably connected to the side wall of the main shaft plate 105a-3, and a helical gear 105a-5 fixedly installed on the side wall of the main shaft plate 105a-3.

[0029] Furthermore, the helical gear 105a-5, when used in conjunction with the transmission gear 104, can convert the force rotating around the sewing machine axis into a force rotating around the center of the helical gear 105a-5. When the main shaft plate 105a-3 rotates, it drives the auxiliary shaft plate 105a-4 to rotate in the opposite direction, generating a lifting force in the oil inlet chamber 105a-2, drawing oil from the bottom and discharging it from the top.

[0030] The auxiliary component 105b includes a connecting pipe 105b-1 connected to the side wall of the fixed housing 105a-1, and a nozzle 105b-2 connected to the side wall of the connecting pipe 105b-1. The auxiliary component 105b also includes an oil tank 105b-3 fixedly installed at the bottom of the mounting base 101, an oil suction box 105b-4 fixedly connected to the inner wall of the oil tank 105b-3, and an oil extraction pipe 105b-5 connected to the side wall of the oil suction box 105b-4.

[0031] Preferably, the bottom of the oil suction box 105b-4 has a hole to facilitate the suction of lubricating oil from the oil tank 105b-3 into the oil chamber 105a-2. At the same time, excess lubricating oil will flow back into the oil tank 105b-3 through the inner cavity of the sewing machine housing 102. The main shaft plate 105a-3, in conjunction with the auxiliary shaft plate 105a-4, delivers lubricating oil into the connecting pipe 105b-1, and sprays the lubricating oil to the areas requiring lubrication through the nozzle 105b-2.

[0032] It should be noted that the transmission gear 104 meshes with the helical gear 105a-5, and the end of the oil extraction pipe 105b-5 is connected to the bottom of the fixed housing 105a-1.

[0033] During use, multiple nozzles 105b-2 are installed according to the areas of the sewing machine that require lubrication. Lubricating oil is added to the oil tank 105b-3. When the sewing machine is running, the main shaft of the sewing machine rotates, driving the helical gear 105a-5 to rotate. The rotation of the helical gear 105a-5 drives the main shaft plate 105a-3 to rotate. The rotation of the main shaft plate 105a-3 drives the auxiliary shaft plate 105a-4 to rotate in the opposite direction. A negative pressure is generated below the main shaft plate 105a-3 and the auxiliary shaft plate 105a-4. With the help of the oil suction pipe 105b-5, the lubricating oil is lifted into the oil inlet chamber 105a-2. The lubricating oil in the oil inlet chamber 105a-2 is squeezed out from above the main shaft plate 105a-3 and the auxiliary shaft plate 105a-4. With the help of the connecting pipe 105b-1, the lubricating oil is transferred to the nozzle 105b-2, and the lubricating oil is sprayed onto the lubrication point through the nozzle 105b-2.

[0034] In summary, by setting multiple nozzles 105b-2 at key lubrication points of the sewing machine and adding lubricating oil to the oil trough 105b-3, an automatic and efficient lubrication process is achieved. When the sewing machine is running, the rotation of the main shaft generates negative pressure through the cooperation of gears and shaft plates, drawing lubricating oil into the oil inlet chamber 105a-2. The rotation of the shaft plates then squeezes the lubricating oil to the nozzles 105b-2, ultimately spraying it evenly to each lubrication point. This ensures continuous lubrication of the equipment, significantly improves the operational stability and service life of the sewing machine, and reduces wear and maintenance costs caused by insufficient lubrication.
