Description

Technical Field

[0001] This utility model relates to the technical field of warp knitting machine lubricating oil recovery, filtration and reuse device, specifically a warp knitting machine lubricating oil recovery, filtration and reuse device. Background Technology

[0002] The main loop-forming components of a warp knitting machine include knitting needles, guide needles, sinkers, and pressure plates. The knitting needles are arranged in rows on the needle bed and move with it. The guide needles are mounted on a slat to form guide bars. The warp yarns pass through the holes in the guide needles and move with the guide bars, wrapping around the needles. Through the coordinated movement of the knitting needles, sinkers, and other loop-forming components, the fabric is woven. To reduce friction between the various mechanical parts on the warp knitting machine, lubricating oil is often sprayed onto the parts to protect them. The lubricating oil mainly functions as lubricant, coolant, rust preventer, cleaner, sealant, and buffer. After flowing to the friction points of the mechanical parts, the lubricating oil adheres to the friction surfaces, forming an oil film that reduces resistance between the frictional parts. The strength and toughness of the oil film are key to its lubricating effect.

[0003] Currently, the existing lubrication system of warp knitting machines is relatively simple, only realizing the circulation of lubricating oil. After long-term use, the lubricating oil will contain a large amount of fiber debris, metal shavings, etc., which will greatly reduce its lubrication effect and increase the wear of the transmission system inside the warp knitting machine, thus reducing the service life of the warp knitting machine. Therefore, it is necessary to propose a lubricating oil recovery, filtration and reuse device for warp knitting machines. Utility Model Content

[0004] To address the shortcomings of existing technologies, where existing warp knitting machine lubricating oil contains a large amount of fiber debris and metal shavings after prolonged use, leading to increased wear on the transmission system and reduced service life, this invention proposes a warp knitting machine lubricating oil recovery, filtration, and reuse device.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a warp knitting machine lubricating oil recovery, filtration and reuse device, including a lower shell, a magnetic block is provided on one side of the lower shell, an upper shell is provided on the top of the lower shell, an oil injection hole is provided on one side of the upper shell, a controller is fixedly connected to the top of the upper shell, and a circulation filtration mechanism is provided in the inner cavity of the upper shell;

[0006] The circulating filtration mechanism includes an oil pump, which is fixedly connected to the top of the upper housing. An oil suction pipe is provided on one side of the oil pump, and a first filter pipe is provided on the other side of the oil pump. A filter is provided at one end of the first filter pipe, and a second filter pipe is provided at one end of the filter. A pressure regulating valve is provided at one end of the second filter pipe, and an oil outlet pipe is provided on one side of the pressure regulating valve. An oil inlet pipe is provided on one side of the upper housing.

[0007] Preferably, the top of the lower housing is provided with an inclined surface, the magnetic blocks are fixedly connected to the upper surface of the inclined surface, and gaps are provided between the magnetic blocks.

[0008] Preferably, a temperature sensor is provided on one side of the upper housing, with one end of the temperature sensor extending to the bottom of the inner cavity of the lower housing.

[0009] Preferably, a liquid level sensor is provided on the side of the upper housing near the temperature sensor, and one end of the liquid level sensor extends to the bottom of the inner cavity of the lower housing.

[0010] Preferably, one end of the oil pump extends into the inner cavity of the upper housing, and one end of the oil suction pipe extends into the bottom of the inner cavity of the lower housing.

[0011] Preferably, the filter is threaded to the bottom of the lower housing, and one end of the filter extends through the inner cavity of the lower housing.

[0012] Preferably, one end of the pressure regulating valve extends into the inner cavity of the upper housing, and one end of the oil outlet pipe extends into the outer side of the upper housing.

[0013] The utility model is beneficial in that:

[0014] This invention introduces external lubricating oil into the bottom of the lower housing via an oil inlet pipe. The lubricating oil flows through the gap between magnetic blocks to the end of the suction pipe. The magnetic blocks can adsorb iron filings and impurities in the external lubricating oil. An oil pump draws the lubricating oil from the bottom of the lower housing through the suction pipe to the outlet pipe. The lubricating oil passes through a first filter pipe, a filter, a second filter pipe, and a pressure regulating valve before being discharged from the outlet pipe. The filter removes fiber impurities, thus achieving the effect of circulating and filtering the lubricating oil. This solves the problem that existing warp knitting machine lubricating oil contains a large amount of fiber filings and metal shavings after long-term circulation, leading to increased wear and reduced service life of the warp knitting machine's transmission system.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] The following is combined with Figure 1-5 This application will be described in further detail.

[0024] This application discloses a device for recovering, filtering, and reusing lubricating oil in a warp knitting machine. (Refer to...) Figure 1-Figure 5 A device for recycling and reusing lubricating oil in a warp knitting machine includes a lower housing 1, a magnetic block 12 on one side of the lower housing 1, an upper housing 2 on the top of the lower housing 1, an oil injection hole 21 on one side of the upper housing 2, a controller 4 fixedly connected to the top of the upper housing 2, and a circulation filtration mechanism 3 in the inner cavity of the upper housing 2. The controller 4 on the top of the upper housing 2 controls the circulation filtration mechanism 3 to first introduce external lubricating oil into the lower housing 1. The external lubricating oil flows through the gap of the magnetic block 12 to the lowest end of the lower housing 1. The magnetic block 12 can filter out iron filings and impurities in the lubricating oil. Then the circulation filtration mechanism 3 draws out the lubricating oil from the bottom of the lower housing 1 for reuse. During the drawing out process, fiber impurities are filtered out, so that the lubricating oil can be recycled and reused.

[0025] The circulating filtration mechanism 3 includes an oil pump 31, which is fixedly connected to the top of the upper housing 2. An oil suction pipe 32 is provided on one side of the oil pump 31, and a first filter pipe 33 is provided on the other side of the oil pump 31. A filter 34 is provided at one end of the first filter pipe 33, and a second filter pipe 35 is provided at one end of the filter 34. A pressure regulating valve 36 is provided at one end of the second filter pipe 35. An oil outlet pipe 37 is provided on one side of the pressure regulating valve 36, and an oil inlet pipe 38 is provided on one side of the upper housing 2. The oil pump 31 draws lubricating oil from the lowest end of the lower housing 1 through the oil suction pipe 32. The lubricating oil enters the filter 34 through the first filter pipe 33, where fiber impurities in the lubricating oil are filtered out. Then, the lubricating oil enters the pressure regulating valve 36 through the second filter pipe 35, and is then led out from the second pressure regulating valve 36 through the oil outlet pipe 37, thereby achieving the purpose of circulating filtration of lubricating oil.

[0026] Reference Figure 1 , Figure 3 and Figure 5 The lower housing 1 has an inclined surface 11 at its top, and magnetic blocks 12 are fixedly connected to the upper surface of the inclined surface 11. There is a gap between the magnetic blocks 12. A temperature sensor 22 is provided on one side of the upper housing 2, with one end of the temperature sensor 22 extending to the bottom of the inner cavity of the lower housing 1. A liquid level sensor 23 is provided on the side of the upper housing 2 near the temperature sensor 22, with one end of the liquid level sensor 23 extending to the bottom of the inner cavity of the lower housing 1. External lubricating oil is introduced into the lower housing 1 through the oil inlet pipe 38. The lubricating oil flows downward through the inclined surface 11 and flows into the lowest end of the lower housing 1 through the gap of the magnetic blocks 12. The magnetic blocks 12 can adsorb iron filings in the lubricating oil, thereby filtering out the iron filings in the lubricating oil. The temperature of the lubricating oil is detected in real time by the temperature sensor 22, which can identify whether the lubricating oil has solidified. The liquid level sensor 23 detects the liquid level of the lubricating oil in real time. When the lubricating oil is low, lubricating oil can be added again through the oil filling hole 21 on the upper housing 2.

[0027] Reference Figure 2 , Figure 3 and Figure 4 One end of the oil pump 31 extends into the inner cavity of the upper housing 2, and one end of the oil suction pipe 32 extends into the bottom of the inner cavity of the lower housing 1. The filter 34 is threadedly connected to the bottom of the lower housing 1, and one end of the filter 34 penetrates into the inner cavity of the lower housing 1. One end of the pressure regulating valve 36 extends into the inner cavity of the upper housing 2, and one end of the oil outlet pipe 37 extends to the outside of the upper housing 2. It extends to the lowest end of the lower housing 1 through the oil suction pipe 32, so that the oil pump 31 can draw lubricating oil from the lowest end of the lower housing 1. The filter 34 is threadedly installed at the bottom of the lower housing 1, so that the filter 34 can be disassembled and replaced. The pressure regulating valve 36 detects the delivery pressure of the lubricating oil in real time and controls the delivery pressure in conjunction with the controller 4 to improve the stability of the lubricating oil delivery.

[0028] Working principle: During use, the controller 4 on the top of the upper housing 2, in conjunction with the circulating filter mechanism 3, circulates and filters the lubricating oil to achieve reuse. External lubricating oil is introduced through the oil inlet pipe 38 and flows into the inclined surface 11 of the lower housing 1 and into the lowest end of the lower housing 1 through the gap of the magnetic block 12. Iron filings in the lubricating oil are adsorbed and filtered by the magnetic block 12. The oil pump 31 and the oil suction pipe 32 are used to draw the lubricating oil from the bottom of the lower housing 1. The lubricating oil enters the filter 34 through the first filter pipe 33. After the fiber debris in the lubricating oil is filtered by the filter 34, it passes through the second filter pipe 35 and the pressure regulating valve 36 and is discharged from the oil outlet pipe 37. The temperature sensor 22 detects the temperature of the lubricating oil in real time, which can easily identify whether the lubricating oil has condensed. The liquid level sensor 23 detects the liquid level of the lubricating oil in the inner cavity of the lower housing 1 in real time. When the lubricating oil is low, new lubricating oil can be introduced in time through the oil filling hole 21, thereby achieving the purpose of lubricating oil recycling, filtration and reuse.

[0029] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
