[0001] This utility model relates to the field of oil supply technology for rotary hooks of quilting machines, specifically to an oil supply device for rotary hooks of quilting machines. Background Technology

[0002] The lubrication system for the rotary hook of a quilting machine is designed to ensure effective lubrication of the hook during operation, thereby reducing friction and wear and improving the machine's efficiency and lifespan. The rotary hook is a crucial component of the quilting machine; timely lubrication ensures smooth operation and prevents damage to parts caused by heat generated from friction.

[0003] The shortcomings of existing technology:

[0004] Currently, most quilting machine rotary hook oil supply devices do not have external oil supply for lubrication and cooling, which makes the rotary hook prone to overheating, jamming, and wear, thus significantly shortening its service life. Utility Model Content

[0005] The purpose of this invention is to provide an oil supply device for a rotary hook of a quilting machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rotary hook oil supply device for a quilting machine, comprising an oil storage tank, a cover fixedly connected to the top surface of the oil storage tank, a cooling mechanism for cooling oil being provided inside the cover, and disassembly and assembly mechanisms for installing the oil storage tank being provided on both sides of the oil storage tank, the cooling mechanism comprising:

[0007] A fan is disposed inside the cover, and a limiting groove adapted to the fan is provided on the surface of the cover;

[0008] A mesh, which is fixedly connected to the top surface of the fan;

[0009] An electric slide rail is connected to one side of the top surface of the cover.

[0010] A cleaning brush is slidably connected to one side of an electric slide rail, with the bottom surface of the cleaning brush attached to the top surface of the grid.

[0011] Preferably, the disassembly and assembly mechanism includes:

[0012] L-plates, which are fixedly connected to both sides of the oil storage tank;

[0013] Telescopic rod, which is welded to one side of the L-plate;

[0014] A grab hook, which is fixedly connected to one end of the telescopic rod;

[0015] A rotating shaft is rotatably connected to the top of the grab hook, and one side of the rotating shaft is welded to the surface of the L-plate.

[0016] Preferably, an oil pump is connected to the outer surface of the oil tank, one end of the oil pump is connected to a connecting pipe, and an oil temperature sensor is connected to the surface of the connecting pipe.

[0017] Preferably, the inner surface of the connecting pipe is provided with a threaded hole, and a threaded joint is connected to the inside of the threaded hole.

[0018] Preferably, one end of the threaded joint is fixedly connected to a delivery pipe to facilitate the delivery of oil from the oil storage tank to the rotary hook via an oil pump.

[0019] Preferably, a protective shell is fixedly connected to the outer surface of the oil pump to facilitate the protection of the oil pump.

[0020] Preferably, one end of the oil storage tank is connected to an oil inlet pipe, and the surface of the oil inlet pipe is threaded with a screw cap.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. The oil supply device for a quilting machine rotary hook includes a cooling mechanism comprising a fan, a mesh, an electric slide rail, and a disassembly mechanism. When the lubricating oil temperature sensor detects that the temperature of the lubricating oil transported in the connecting pipe exceeds the preset temperature, the control panel drives the fan to dissipate heat from the lubricating oil in the oil tank. Subsequently, the electric slide rail drives the cleaning brush to clean the dust on the mesh surface in parallel, preventing dust from adhering to the fan during long-term use and affecting the fan's heat dissipation effect. This helps to cool the lubricating oil and prevents the rotary hook from overheating, jamming, and wearing, thereby significantly shortening its service life.

[0023] 2. This quilting machine rotary hook oil supply device includes an L-plate, a telescopic rod, a hook, and a rotating shaft in its disassembly and assembly mechanism. By rotating the hook away from the central axis of the oil tank using the rotating shaft, the oil tank is placed against the top surface of the fixed plate at the quilting machine mounting location. Then, the hook is released, and the reverse compression force of the spring inside the telescopic rod causes the hook to grip one side of the fixed plate at the quilting machine mounting location, thereby fixing the device. This facilitates disassembly and assembly for later maintenance and improves its practicality. Attached Figure Description

[0033] Example 1

[0034] Please see Figure 1-4As shown, this utility model provides a technical solution for a rotary hook oil supply device for a quilting machine: it includes an oil tank 1, a cover 2 fixedly connected to the top surface of the oil tank 1, a cooling mechanism 3 for cooling oil inside the cover 2, and installation and disassembly mechanisms 4 for the oil tank 1 on both sides. The cooling mechanism 3 includes a fan 301, a mesh 302, an electric slide rail 303, and the disassembly and disassembly mechanisms 4. The fan 301 is located inside the cover 2, and a limiting groove adapted to the fan 301 is opened on the surface of the cover 2. The mesh 302 is fixedly connected to the top surface of the fan 301, and the electric slide rail 303 is connected to one side of the top surface of the cover 2. The brush 304 is slidably connected to one side of the electric slide rail 303. The bottom surface of the cleaning brush 304 is attached to the top surface of the grid 302. When the lubricating oil temperature sensor 7 detects that the temperature of the lubricating oil transported in the connecting pipe 6 exceeds the preset temperature, the control panel drives the fan 301 to dissipate heat from the lubricating oil in the oil tank 1. Then, the electric slide rail 303 drives the cleaning brush 304 to clean the dust in parallel on the surface of the grid 302. This prevents dust from adhering to the fan 301 during long-term use, which would affect the heat dissipation effect of the fan 301 and help cool the lubricating oil. This also prevents the rotary shuttle from overheating, getting stuck, and wearing out, which would significantly shorten its service life.

[0035] The disassembly and assembly mechanism 4 includes an L-plate 401, a telescopic rod 402, a grab hook 403, and a rotating shaft 404. The L-plate 401 is fixedly connected to both sides of the oil tank 1. The telescopic rod 402 is welded to one side of the L-plate 401. The grab hook 403 is fixedly connected to one end of the telescopic rod 402. The rotating shaft 404 is rotatably connected to the top of the grab hook 403. One side of the rotating shaft 404 is welded to the surface of the L-plate 401. By rotating the grab hook 403 away from the central axis of the oil tank 1 using the rotating shaft 404, the oil tank 1 is attached to the top surface of the fixed long plate of the quilting machine installation part. Then, the grab hook 403 is released, and the reverse squeezing force of the spring in the telescopic rod 402 causes the grab hook 403 to grab one side of the fixed long plate of the quilting machine installation part, thereby fixing the device. This facilitates disassembly and assembly of the device for later maintenance and improves its practicality.

[0036] An oil pump 5 is connected to the outer surface of the oil tank 1. One end of the oil pump 5 is connected to a connecting pipe 6. An oil temperature sensor 7 is connected to the surface of the connecting pipe 6 to facilitate temperature detection of the lubricating oil transported in the connecting pipe 6, so as to cool down the lubricating oil.

[0037] The inner surface of the connecting pipe 6 is provided with a threaded hole 10, and the threaded hole 10 is connected to a threaded connector 9, which facilitates the disassembly, assembly and maintenance of the conveying pipe 8 in the later stage.

[0038] One end of the threaded connector 9 is fixedly connected to a delivery pipe 8, which facilitates the delivery of oil from the oil storage tank 1 to the rotary hook via the oil pump 5.

[0039] The outer surface of the oil pump 5 is fixedly connected to a protective shell 11 for convenient protection of the oil pump 5.

[0040] One end of the oil reservoir 1 is connected to an oil inlet pipe 12, and the surface of the oil inlet pipe 12 is threaded with a cap 13, which facilitates the pouring of lubricating oil into the oil reservoir 1 and also prevents foreign objects from adhering to the oil reservoir 1.

[0041] In this device, the rotating shaft 404 rotates the hook 403 to a side away from the central axis of the oil tank 1, thereby attaching the oil tank 1 to the top surface of the fixing plate of the quilting machine mounting location. Then, the hook 403 is released, and the reverse compression force of the spring inside the telescopic rod 402 causes the hook 403 to grip one side of the fixing plate of the quilting machine mounting location, thus fixing the device. This facilitates disassembly and assembly for later maintenance, improving its practicality. When using the device, lubricating oil is poured into the oil tank 1, which then drives the oil pump 5 to transport the lubricating oil to the delivery pipe 8. 8. The lubricating oil is delivered to the rotary hook. When the lubricating oil temperature sensor 7 detects that the temperature of the lubricating oil transported in the connecting pipe 6 exceeds the preset temperature, the control panel drives the fan 301 to dissipate heat from the lubricating oil in the oil tank 1. Then, the electric slide rail 303 drives the cleaning brush 304 to clean the dust in parallel on the surface of the grid 302. This prevents dust from adhering to the fan 301 during long-term use, which would affect the heat dissipation effect of the fan 301 and help cool the lubricating oil. This prevents the rotary hook from overheating, jamming, and wearing out, which would greatly shorten its service life.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
