Abstract
Description
Technical Field
[0001] This application relates to the field of oil return technology, specifically to an oil return structure for a stretching machine oil tank. Background Technology
[0002] Stretching machines are common equipment in the general stretching manufacturing industry. The use of stretching oil plays a very important role in the stretching industry. In order to ensure the quality of stretching, oil-based stretching oil is an important component of the stretching production process.
[0003] In the continuous stretching process, the stretching oil plays a very important role. The oil return system and the quality of the stretching oil determine the product quality during the stretching process.

[0040] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0041] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0042] like Figures 1-2 As shown, this application provides an oil return structure for a stretching machine oil tank, including an oil tank 1, which is placed at the lower end of the stretching machine to facilitate the collection of stretching oil. The oil tank 1 is divided into a filter chamber 3 and a temporary storage chamber 5, thereby achieving the subsequent filtration and collection of the stretching oil.
[0043] Meanwhile, the filter chamber 3 is located on one side of the oil tank 1, and multiple sets of baffles 32 are fixedly installed on the upper end of the filter chamber 3, thereby dividing the upper end of the filter chamber 3 into four similarly sized compartments. At the same time, a first filter screen 31 is fixedly installed at the lower end of the compartments at both ends, thereby dividing the filter chamber 3 into a filter chamber located at the upper end of the filter chamber 3 and a settling chamber 30 located at the lower end of the filter chamber 3, so that when the stretching oil is introduced into the oil tank 1, water and impurities can be separated by settling.
[0044] Furthermore, a second filter screen 33 is detachably installed on the baffle 32, thereby forming an S-shaped oil passage in the filter chamber at the upper end of the filter chamber 3. Before the stretching oil needs to be filtered, the stretching oil is first introduced into the oil tank 1 through the groove on one side. During the introduction process, since the density of oil is usually lower than that of water, when it is introduced, the water in the stretching oil will settle in the settling chamber 30 at the bottom of the filter chamber 3, while the oil will float in the filter chamber at the upper end of the filter chamber 3. At the same time, the first filter screen 31 will also filter it to different degrees.
[0045] After the oil and water are separated, the oil floating on the surface will be filtered gradually through the first filter screen 31 along the S-shaped oil path. It should be noted that the density of the first filter screen 31 and the second filter screen 33 gradually increases along the S-shaped oil path so that the oil floating on the surface can be filtered smoothly.
[0046] An overflow port 35 is provided on one side of the filter chamber 3. The overflow port 35 is connected to the temporary storage chamber 5. The overflow port 35 is made of stainless steel mesh welded together so that the filtered oil can be introduced into the temporary storage chamber 5 through the overflow port 35.
[0047] Meanwhile, a third oil filter 50 is detachably installed inside the temporary storage chamber 5. The third filter 50 is located at the lower end of the overflow port 35 so that the oil introduced into the temporary storage chamber 5 can be filtered for the last time. It should be noted that the oil introduced into the temporary storage chamber 5 through the overflow port 35 will float on the surface during the introduction process because the density of oil is usually lower than that of water, so it can be filtered by the third filter 50. A cover 51 is detachably installed at the upper end of the temporary storage chamber 5. The cover 51 is used to prevent dust from entering the temporary storage chamber 5 and contaminating the oil. At the same time, an oil drain port 52 and a monitoring port 53 are opened at the upper end of the cover 51. The oil drain port 52 and the monitoring port 53 are used for subsequent oil suction operations and subsequent oil level monitoring. At the same time, drain ports 34 are fixedly installed at the lower end on both sides of the oil tank 1. The drain ports 34 are used to drain the remaining impurities and water after filtration.
[0048] like Figure 1 and Figures 3-4 As shown, in order to eliminate bubbles during the oil return process, a bubble filter mechanism 2 is provided at the oil outlet 52. The bubble filter mechanism 2 includes a pipe 20 fixedly installed at the oil outlet 52. A cover 21 is fixedly installed on the outside of the pipe 20, and a slide 22 is provided on the cover 21. The slide 22 passes through the cover 21 and extends into the inside of the pipe 20.
[0049] Meanwhile, a slide plate 23 is slidably installed in the slide 22, and an installation hole 24 is provided inside the slide plate 23. A filter screen 25 is detachably installed in the installation hole 24. The filter screen 25 covers the pipe 20 to facilitate the subsequent blocking of bubbles. A protruding end is provided at the upper end of the slide plate 23, so that the slide plate 23 can be slid along the slide 22 by pulling the protruding end.
[0050] In order to facilitate the removal of the filter screen 25 for subsequent cleaning, a mounting platform 28 is fixedly provided on the cover 21. A connecting shaft (not shown in the figure) is rotatably provided on the mounting platform 28, and gears 27 are fixedly provided at both ends of the connecting shaft. At the same time, racks 26 are fixedly provided on both sides of the upper protruding end of the slide plate 23. The racks 26 mesh with the gears 27, so that the gears 27 can be rotated to drive the slide plate 23 to slide along the slide rail 22 through the racks 26.
[0051] Meanwhile, one end of the connecting shaft passes through the gear 27 and is fixedly connected to a handle 29. The handle 29 is used to drive the gear 27 to rotate. So when the filter screen 25 needs to be cleaned, the staff only needs to turn the handle 29, and use the gear 27 to drive the rack 26, so that the slide plate 23 slides upward along the slide rail 22. At this time, the filter screen 25 slides out of the cover 21 with the slide plate 23, and then the filter screen 25 can be cleaned.
[0052] like Figure 1 and Figure 3 and Figure 5 As shown, in order to further reduce the oil temperature and eliminate foaming, a cooling component 4 is provided at one end of the pipe 20. The cooling component 4 includes a housing 40, and a cover plate (not shown in the figure) is fixedly provided at one end of the housing 40. Multiple sets of oil delivery pipes 41 are fixedly provided on the cover plate. The oil delivery pipes 41 pass through the cover plate and extend to the outside. At the same time, a cavity is fixedly provided at the other end of the cover plate. The cavity is connected to the multiple sets of oil delivery pipes 41. An oil inlet 42 is fixedly provided at the other end of the cavity so that the filtered oil can be introduced into the oil delivery pipes 41.
[0053] Meanwhile, an inlet 43 and an outlet 44 are fixedly provided on both sides of the housing 40. The inlet 43 and the outlet 44 are used to introduce and discharge the cooling medium. After the filtered oil is introduced into the oil pipe 41 through the oil inlet 42, the cooling medium can be introduced into the housing 40 to achieve the cooling effect. The oil pipe 41 passes through the housing 40 and an outlet 45 is fixedly provided at the other end to discharge the oil for subsequent use.
[0054] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
