Description

Technical Field

[0001] This invention relates to the field of sewing machine technology, specifically to an intelligent sewing device with an oil level detection mechanism. Background Technology

[0002] A sewing machine is a machine that uses one or more sewing threads to create one or more stitches on fabric, so that one or more layers of fabric are interwoven or sewn together.

[0003] In the prior art, a utility model patent with publication number CN216473863U and titled "A Multifunctional Sewing Machine" includes a sewing machine head with an installation cavity inside; it also includes an oil reservoir, a piston, and a conduit. The oil reservoir and the conduit are both located within the installation cavity and connected to the sewing machine head. The piston is dynamically sealed to the inner wall of the oil reservoir. The sewing machine head has an adjustment window, and the piston is located within the adjustment window. One end of the conduit communicates with the oil reservoir, and the other end of the conduit has an oil outlet. The advantage of this multifunctional sewing machine is that adding lubricating oil is very convenient.

[0004] The device of this patent can squeeze the lubricating oil in the oil storage box into the conduit by manually adjusting the position of the piston from the adjustment window. Then the lubricating oil is squeezed out from the oil outlet to the transmission component in the mounting cavity, thereby realizing the function of adding lubricating oil to the transmission component of the multi-functional sewing machine. However, the device of this patent still has the following technical defects in use: (1) The device of this patent adds lubricating oil by manually adjusting the position of the piston, which is inconvenient to accurately measure the amount of lubricating oil used. Too little lubricating oil will affect the subsequent operation of the machine, while too much lubricating oil will cause waste of lubricating oil, thus making it inconvenient to meet the needs of the staff; (2) Since the quality of the lubricating oil added to the oil storage box is different, and the device of this patent does not filter the lubricating oil before adding it, some impurities in the oil are easy to damage the sewing machine structure, thus making it inconvenient to use the equipment. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent sewing device with an oil level detection mechanism.

[0006] The technical problems solved by the present invention are: (1) the existing equipment adds lubricating oil by manually adjusting the position of the piston, which is inconvenient to accurately measure the amount of lubricating oil used; (2) due to the different quality of the added lubricating oil, the existing equipment does not filter the lubricating oil before adding it, which causes some impurities in the oil to easily damage the sewing machine structure.

[0007] This invention can be achieved through the following technical solution: an intelligent sewing device with an oil quantity detection mechanism, comprising a transmission component and an oil storage tank inside the sewing machine head, with an oil drain pipe fixedly connected to the bottom of one side of the oil storage tank for supplying oil to the transmission component, the inner cavity of the oil storage tank having an oil storage area and a lubricating oil quantitative supply area arranged sequentially from top to bottom, the oil storage area and the lubricating oil quantitative supply area being connected by a connecting channel, a blocking block for blocking the connecting channel being vertically slidably connected to the inner cavity of the oil storage area, and a driving component for vertically sliding the blocking block being provided at the top of the inner cavity of the oil storage area, the driving component being able to control the upward movement time of the blocking block, thereby facilitating accurate single-use of lubricating oil, and facilitating better machine operation by accurately detecting the amount of lubricating oil used, thereby meeting the needs of the operator;

[0008] The inner cavity of the connecting channel is equipped with a lubricating oil filter assembly, which includes filter cotton that slides through the back of the oil tank and extends into the inner cavity of the connecting channel. The filter cotton is used to filter the lubricating oil before use, thereby preventing some impurities in the oil from damaging the sewing machine structure.

[0009] A further technical improvement of the present invention is that: the driving component includes an outer sleeve fixedly connected to the top of the inner cavity of the oil storage area, an inner sleeve fixedly connected to the sealing block in the inner cavity of the outer sleeve, a first electromagnetic block fixedly installed in the inner cavity, and a second electromagnetic block with opposite magnetism to the first electromagnetic block fixedly installed on the inner sleeve, and the first electromagnetic block and the second electromagnetic block attract each other when energized.

[0010] A further technical improvement of the present invention is that: the filter cotton includes a mounting frame fixedly connected to its bottom end, the mounting frame being used to better fix the filter cotton; a side plate is fixedly mounted on one side of the mounting frame.

[0011] A further technical improvement of the present invention is that the side plate and the oil tank are connected by a sealing element. The sealing element includes a rectangular insert frame fixedly connected to one side of the side plate. A rectangular frame groove that matches the rectangular insert frame is provided on the back of the oil tank. A first magnetic frame is elastically slidably connected to the inner cavity of the rectangular insert frame. A second magnetic frame with opposite magnetism to the first magnetic frame is fixedly installed on the inner wall of the rectangular frame groove. The sealing element facilitates the sealing of the filter cotton installation, thereby facilitating the subsequent use of the filter cotton.

[0012] A further technical improvement of the present invention is that two circular rods are symmetrically fixedly connected to one side of the first magnetic frame. One end of the circular rod passes through the rectangular insert frame and the side plate in sequence and extends to the outside of the side plate. The first magnetic frame can be moved by operating the circular rods.

[0013] A further technical improvement of the present invention is that: a rectangular float plate is vertically slidably connected to the inner cavity of the oil storage area, the rectangular float plate is slidably connected to the outer sleeve, and two indicator rods are symmetrically fixedly installed on the rectangular float plate. The end of the indicator rod away from the rectangular float plate passes through the oil storage tank and extends to the top of the oil storage tank. Through the cooperation of the rectangular float plate and the two indicator rods fixedly connected to it, it is easier for the staff to know the amount of lubricating oil in the inner cavity of the oil storage area.

[0014] A further technical improvement of the present invention is that a lifting plate for blocking the oil drain pipe is vertically slidably connected between the two inner sidewalls of the lubricating oil metering supply area. When the lifting plate rises, the oil drain pipe is blocked, and when the lifting plate falls, the blockage of the oil drain pipe is released.

[0015] A further technical improvement of the present invention is that: at least one telescopic component for driving the lifting plate to slide vertically is provided at the bottom end of the oil tank. The telescopic component includes a cylinder fixedly connected to the bottom end of the oil tank. A T-shaped rod fixedly connected to the lifting plate is vertically elastically slidably connected to the inner cavity of the cylinder. A third electromagnetic block is fixedly installed in the inner cavity of the T-shaped rod. A fourth electromagnetic block corresponding to the third electromagnetic block is fixedly installed in the inner cavity of the cylinder. The third electromagnetic block and the fourth electromagnetic block are magnetic poles of the same name.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In this invention, when lubricating oil needs to be supplied to the transmission components in the sewing machine head, the power supply to the third and fourth electromagnetic blocks is manually turned on. The magnetic repulsion between the two causes the lifting plate to move upwards. This upward movement of the lifting plate facilitates the sealing of the oil drain pipe. Simultaneously, the upward movement of the lifting plate causes the top ball to be squeezed by the blocking ball. When the top ball is squeezed, it contacts the first trigger switch. The first trigger switch then turns on the power supply to the first and second electromagnetic blocks. Their magnetic attraction causes the blocking block to move upwards. This upward movement of the blocking block allows the lubricating oil in the oil storage area to enter the lubricating oil metering supply area through the connecting channel. In the field, as lubricating oil continuously enters, the rotating float plate rotates. When the rotating float plate rotates, it can block the feed hole through the action of the top ball, thus preventing the lubricating oil from flowing down. After a certain amount of lubricating oil enters, the rotating float plate will contact the second trigger switch. At this time, the second trigger switch will first cut off the power supply to the first and second electromagnetic blocks. After the blocking block resets, it will then cut off the power supply to the third and fourth electromagnetic blocks, so that a certain amount of lubricating oil can enter the transmission components through the oil drain pipe. By accurately detecting the amount of lubricating oil used, the machine can operate better, thus meeting the needs of the operators.

[0018] 2. Before the lubricating oil enters the lubricating oil metering area, the present invention uses filter cotton to facilitate the filtration of impurities in the lubricating oil. This filtration prevents some impurities in the oil from damaging the sewing machine structure. Furthermore, the detachable design of the filter cotton and the oil tank allows the equipment to be cleaned periodically according to the user's needs. When the filter cotton needs to be removed, first pull the two circular rods to move the first magnetic frame away from the second magnetic frame, and then pull the filter cotton out of the oil tank to complete the removal. After removal, it can be cleaned and then reinstalled. During installation, the filter cotton is first slid into the inner cavity of the oil tank and the rectangular insert frame is inserted into the inner cavity of the corresponding rectangular frame slot. The magnetic attraction between the first and second magnetic frames ensures the airtightness of the filter cotton and the oil tank, thus facilitating subsequent use by the user.

The end of the indicator rod 271 away from the rectangular float plate 27 passes through the oil storage tank 2 and extends to the top of the oil storage tank 2.

[0041] The inner cavity of the lubricating oil metering supply area 24 is equipped with a time-limiting component that enables the power supply of the first electromagnetic block 254 and the second electromagnetic block 255 for a limited time. The time-limiting component includes a support plate 3 fixed in the middle of the inner cavity of the lubricating oil metering supply area 24. Multiple rotating float plates 32 are rotatably connected at equal intervals on the support plate 3. Guide inclined plates 39 are fixedly installed on the support plate 3 and on both the front and back of the rotating float plates 32. A stopper bead 33 is fixedly installed on the side of the rotating float plate 32 near the support plate 3. The inner cavity of the support plate 3 has a discharge hole 31 that corresponds one-to-one with the stopper bead 33. The height of the discharge hole 31 is less than the radius of the plug bead 33. The inner cavity of the lubricating oil metering supply area 24 and below the support plate 3 is vertically slidably connected to a lifting plate 34. A fixed sleeve 35 corresponding to the discharge hole 31 is fixedly installed on the lifting plate 34. A top ball 36 for squeezing the plug bead 33 is vertically elastically slidably connected to the inner cavity of the fixed sleeve 35. A first trigger switch 37 corresponding to the top ball 36 is fixedly installed at the bottom of the inner cavity of the fixed sleeve 35. The first electromagnetic block 254 and the second electromagnetic block 255 are both electrically connected to the first trigger switch 37.

[0042] At least one telescopic component 310 for driving the lifting plate 34 to slide vertically is provided at the bottom end of the oil tank 2. The telescopic component 310 includes a cylinder 3101 fixedly connected to the bottom end of the oil tank 2. A T-shaped rod 3102 fixedly connected to the lifting plate 34 is vertically elastically slidably connected to the inner cavity of the cylinder 3101. A third electromagnetic block 3103 is fixedly installed in the inner cavity of the T-shaped rod 3102. A fourth electromagnetic block 3104 corresponding to the third electromagnetic block 3103 is fixedly installed in the inner cavity of the cylinder 3101. The third electromagnetic block 3103 and the fourth electromagnetic block 3104 are magnetic poles of the same name. Two second trigger switches 38 are symmetrically fixedly installed at the bottom end of the partition plate 22. The first electromagnetic block 254, the second electromagnetic block 255, the third electromagnetic block 3103, and the fourth electromagnetic block 3104 are all electrically connected to the second trigger switches 38.

[0043] The bottom of one side of the oil tank 2 is fixedly connected to the oil drain pipe 4. When the lifting plate 34 rises, it can block the oil drain pipe 4. When the lifting plate 34 falls, it can release the blockage of the oil drain pipe 4. The end of the oil drain pipe 4 away from the oil tank 2 is connected to multiple conduits 5 through a connector. The oil outlet of the conduit 5 is connected to the transmission component in the sewing machine head 1.

[0044] In use, a certain amount of lubricating oil is first injected into the oil storage area 23 of the oil storage tank 2 through the oil filling port in the cover plate 21 at the top of the oil storage tank 2. When injecting lubricating oil, the rectangular float plate 27 in the oil storage area 23 moves upward with the liquid level of the lubricating oil due to the continuous injection of lubricating oil. The indicator rod 271 fixedly connected to the rectangular float plate 27 makes it easy for the staff to judge the amount of lubricating oil added. By adding a sufficient amount of lubricating oil in advance, the equipment lubricating oil can be used multiple times without the need for the staff to add it repeatedly.

[0045] When lubricating oil needs to be supplied to the transmission components in the sewing machine head 1, the power supply to the third electromagnetic block 3103 and the fourth electromagnetic block 3104 is manually turned on. Their magnetic repulsion causes the lifting plate 34 to move upwards. This upward movement of the lifting plate 34 facilitates the sealing of the oil drain pipe 4. Simultaneously, the upward movement of the lifting plate 34 causes the top ball 36 to be squeezed by the blocking ball 33. When the top ball 36 is squeezed, it contacts the first trigger switch 37. The first trigger switch 37 then turns on the power to the first electromagnetic block 254 and the second electromagnetic block 255. Their magnetic attraction causes the sealing block 26 to move upwards. This upward movement of the sealing block 26 allows the lubricating oil in the oil storage area 23 to enter the lubricating oil metering supply area 24 through the connecting channel. As lubricating oil continuously enters, the rotating float plate 32 rotates. When rotating, the rotating float plate 32 can block the discharge hole 31 through the action of the top ball 36. By blocking it, the lubricating oil is prevented from continuing to flow down along the discharge hole 31. After a certain amount of lubricating oil enters, the rotating float plate 32 will contact the second trigger switch 38. At this time, the second trigger switch 38 will first cut off the power supply to the first electromagnetic block 254 and the second electromagnetic block 255. After the blocking block 26 is reset, the power supply to the third electromagnetic block 3103 and the fourth electromagnetic block 3104 will be cut off. This allows a certain amount of lubricating oil to enter the transmission component through the oil drain pipe 4. By accurately detecting the amount of lubricating oil used, the machine can operate better, thus meeting the needs of the operators.

[0046] Before the lubricating oil enters the lubricating oil metering supply area 24, the filter cotton 210 facilitates the filtration of impurities in the lubricating oil. This filtration prevents some impurities in the oil from damaging the sewing machine structure. Furthermore, the detachable design of the filter cotton 210 and the oil tank 2 allows the equipment to be cleaned periodically according to the operator's needs. When the filter cotton 210 needs to be removed, first pull the two circular rods 214 to move the first magnetic frame 215 away from the second magnetic frame 216, and then pull the filter cotton 210 out of the oil tank 2 to complete the removal. After removal, it is cleaned and then reinstalled. During installation, the filter cotton 210 is slid into the inner cavity of the oil tank 2 and the rectangular insert frame 212 is inserted into the inner cavity of the corresponding rectangular frame groove 213. The magnetic attraction between the first magnetic frame 215 and the second magnetic frame 216 ensures the sealing between the filter cotton 210 and the oil tank 2, thus facilitating subsequent use by the operator.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
