Description

Technical Field

[0001] This invention relates to the field of oil stain rinsing in automotive parts manufacturing, and more particularly to an oil stain rinsing tank for automotive parts manufacturing. Background Technology

[0002] During the manufacturing process of automotive parts, stubborn oil stains such as processing grease, rust-preventive oil, and metal shavings often adhere to the surface of the parts. To ensure the quality of subsequent processes such as painting, welding, or assembly, these oil stains must be thoroughly and effectively cleaned, and the oil stain washing tank is a key piece of equipment in this process.

[0003] However, existing automotive parts oil stain washing technologies have many problems and shortcomings. First, traditional washing equipment typically relies on simple water flow rinsing or high-pressure spraying, lacking effective pretreatment methods for stubborn oil stains that are solidified or have strong adhesion. Without sufficient softening pretreatment, these stubborn oil stains are difficult to remove completely, resulting in poor cleaning effects and even affecting the quality of subsequent processes. Second, during the washing process, the detached oil stains usually float on the water surface, and traditional equipment often lacks an efficient oil stain collection and separation mechanism. This causes the floating oil stains to spread extensively within the tank and may even re-adhere to the surface of the parts with the water flow, causing secondary pollution. Simultaneously, the mixture of waste residue and oil stains is difficult to collect and treat uniformly, increasing the burden and cost of subsequent wastewater treatment. This imperfect oil stain treatment method not only wastes cleaning fluid resources but also easily leads to environmental pollution problems.

[0004] Based on the above situation, there is an urgent need for an oil rinsing tank for automotive parts production. Summary of the Invention

[0005] In order to overcome the shortcomings of traditional equipment that relies solely on simple water rinsing or high-pressure spraying, lacking effective pretreatment methods and oil collection and separation mechanisms, resulting in incomplete cleaning of stubborn oil stains and easy secondary pollution, the technical problem of the present invention is to provide an oil stain rinsing tank for automobile parts production.

[0006] Technical solution: An oil sludge rinsing tank for automotive parts production, comprising a rinsing tank for holding cleaning fluid, a drain pipe with a valve on the rinsing tank, a collection tank on the inner bottom wall of the rinsing tank, symmetrically distributed water pumps installed on the rinsing tank, water pipes connecting the inlets of the pumps to the side walls of the rinsing tank, high-pressure nozzles at the outlets of each pump, symmetrically distributed heating devices on the inner wall of the rinsing tank, and an automated mechanical transfer assembly inside the rinsing tank.

[0007] Furthermore, it is particularly preferred that the automated mechanical transfer assembly includes a first motor mounted on the rinsing tank, the output shaft of which is fixedly connected to a rotating shaft via a coupling. The rotating shaft is rotatably connected to the inner wall of the rinsing tank. Three telescopic rods distributed at a 120° angle are fixedly connected to both ends of the rotating shaft. A soaking basket is provided between the telescopic parts of two telescopic rods at the same horizontal position. Each soaking basket is rotatably connected to the telescopic part of the telescopic rod via a fixed shaft. Symmetrically distributed guide rails are fixedly connected to the inner wall of the rinsing tank, and the soaking baskets slide between the symmetrically distributed guide rails via the fixed shaft.

[0008] Furthermore, it is particularly preferred that toothed rings are fixedly connected to the symmetrically distributed guide rails, and gears are fixedly connected to both ends of each soaking basket. The gears mesh with the adjacent toothed rings to form a gear transmission system.

[0009] Furthermore, it is particularly preferred that each soaking basket is rotatably connected to a rotating cover, each of which has symmetrically distributed insertion holes, and each soaking basket is slidably connected to a locking element, which is connected to an adjacent soaking basket by symmetrically distributed first springs, the first springs being wound around the locking element, and the locking element engaging with the rotating cover.

[0010] Furthermore, it is particularly preferred that a second motor is installed on the rinsing box, the output shaft of which is fixedly connected to a lead screw via a coupling, the lead screw is rotatably connected to the rinsing box, and an oil scraper is threadedly connected to the lead screw, part of which is immersed in the cleaning fluid surface, and symmetrically distributed soft blocks are fixedly attached to the oil scraper.

[0011] Furthermore, it is particularly preferred that the side wall of the rinsing box has an oil drain port precisely opened on the side away from the second motor, and a material extractor is provided at the oil drain port. A material storage device is snapped onto the side wall of the rinsing box, which is located directly below the oil outlet of the material extractor.

[0012] Furthermore, it is particularly preferred that the oil scraper is slidably connected to the striking member, and the two are elastically connected by a second spring. The second spring is wound around the striking member, and a pressing member is fixed inside the striking member. The pressing member can slide horizontally on the flushing box. Symmetrically distributed wedge blocks are fixed on the flushing box, and their surfaces are provided with inclined surfaces. The pressing member is pressed and engaged with the wedge blocks through the inclined surfaces.

[0013] Furthermore, it is particularly preferred that the flushing box is fixedly attached with symmetrically distributed fasteners located directly above the adjacent wedge-shaped block, and the flushing box is rotatably connected to symmetrically distributed movable plates near the oil drain port. These movable plates are inclined and form a ramp structure with the adjacent fasteners. Torsion springs are connected between the movable plates and the flushing box, and each torsion spring is wound around the adjacent movable plate.

[0014] Furthermore, it is particularly preferred that each movable plate is arranged at an angle, forming a ramp structure with the adjacent fixing member.

[0015] Beneficial effects: This invention softens oil stains through pretreatment soaking, and improves cleaning efficiency and stability with automated mechanical transfer; the rotating basket design avoids parts stacking, and the high-pressure nozzles achieve all-around cleaning; the flip-top locking mechanism prevents parts from falling off, ensuring operational safety; automatic waste collection reduces the burden on wastewater treatment. The synergistic effect of these multiple mechanisms significantly improves the cleaning effect and production quality of automotive parts.

[0016] This invention utilizes a second motor to drive the oil scraper and soft block to move horizontally, effectively removing floating oil from the surface of the cleaning fluid, avoiding secondary pollution, and significantly improving the cleaning effect. The elastic deformation characteristics of the soft block ensure it adheres to obstacles and continues operation. Combined with the oil drain, material extractor, and storage unit, it achieves centralized oil treatment, ensuring the cleanliness and efficient operation of the flushing tank, and extending the equipment's service life.

[0017] The present invention uses a reciprocating up-and-down striking component to clean the liquid surface, effectively guiding oil stains from the inner wall and dead corners of components to the center, and working in conjunction with the oil scraping device to achieve thorough cleaning, significantly improving the oil removal effect. The movable plate and the fixed component form a lifting mechanism to ensure the safe repositioning of the oil scraping component, ensuring stable system operation and extending the service life of the equipment.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0026] Example 1: An oil rinsing tank for automotive parts production, such as... Figure 1 and Figure 2 As shown, the system includes a rinsing tank 1 for holding cleaning fluid. The rinsing tank 1 is equipped with a drain pipe 11 with a valve for convenient discharge of used cleaning fluid. A collection tank 12 is located on the inner bottom wall of the rinsing tank 1 to automatically and efficiently collect the washed-out waste residue, preventing it from flowing out with the cleaning fluid and reducing the burden and cost of subsequent wastewater treatment. Symmetrically distributed water pumps 1301 are installed on the rinsing tank 1, with water pipes 1302 connecting their inlets to the side walls of the rinsing tank 1. All outlets of 301 are equipped with high-pressure nozzles 13, which are all positioned facing into the rinsing tank 1. By starting the water pump 1301, the cleaning fluid in the rinsing tank 1 is extracted through the water pipe 1302, and the pre-treated accessories that have been fully softened are powerfully rinsed through the high-pressure nozzles 13 to ensure better cleaning results. In addition, symmetrically distributed heating devices are installed on the inner wall of the rinsing tank 1, which can quickly and evenly heat the cleaning fluid to effectively soften stubborn oil stains and improve cleaning efficiency and cleanliness.

[0027] When cleaning oil stains from manufactured automotive parts, first add cleaning fluid to the flushing tank 1 to a suitable level, then heat the cleaning fluid to approximately 50°C using a heating device. Place the automotive parts to be cleaned into the flushing tank 1 and soak for a period of time to soften stubborn oil stains.

[0028] Next, the softened oil stains on the automotive parts are removed and placed between two high-pressure nozzles 13. The water pump 1301 is started, drawing cleaning fluid from the flushing tank 1 through the water pipe 1302 and spraying it onto the surface of the automotive parts via the high-pressure nozzles 13. Because the oil stains have been sufficiently softened, the high-pressure nozzles 13 can efficiently remove the oil stains adhering to the surface of the parts, ensuring excellent cleaning results. During this process, cleaning waste automatically settles into the collection tank 12 to avoid secondary pollution; after cleaning, the used cleaning fluid can be discharged through the drain pipe 11.

[0029] In the pretreatment process of washing oil stains on automotive parts, traditional manual operation has significant drawbacks. First, workers must manually remove the soaked parts from the washing tank, which is labor-intensive and inefficient, making it difficult to meet the needs of large-scale production. Second, manual control of soaking time lacks precision, easily leading to insufficient soaking time resulting in inadequate softening of the oil stains, or excessive soaking time affecting the subsequent processing of parts, resulting in unstable cleaning effects and impacting production efficiency and product quality. Therefore, there is an urgent need to design an automated mechanical transfer mechanism to achieve orderly and precise transfer of parts from the soaking area to the washing area, ensuring efficient and stable operation of the pretreatment process.

[0030] like Figure 2 As shown, specifically, a first motor 2 is installed on the rinsing tank 1, and its output shaft is fixedly connected to a rotating shaft 21 via a coupling. The rotating shaft 21 is rotatably connected to the inner wall of the rinsing tank 1, providing stable and reliable power support for the entire transmission system. Three telescopic rods 22, distributed at a 120° angle, are fixedly connected to both ends of the rotating shaft 21. A soaking basket 25 is provided between two telescopic rods 22 at the same horizontal position. The soaking basket 25 is rotatably connected to the telescopic part of the telescopic rod 22 via a fixed shaft, forming a rotatable accessory support structure. Symmetrically distributed guide rails 23 are fixedly connected to the inner wall of the rinsing tank 1. These guide rails are composed of two rounded rectangular frames spaced apart. The fixed shaft of the soaking basket 25 is embedded in the frame spaced apart, enabling the soaking basket 25 to slide stably along the guide rail 23. The first motor 2 drives the rotating shaft 21 to rotate, causing the telescopic rods 22, the soaking basket 25, and their internal accessories to move along the guide rail 23, completing the transfer of accessories from the soaking area to the rinsing area.

[0031] During operation, first adjust the cleaning fluid level in the rinsing tank 1 to a position below the highest point of rotation of the soaking basket 25. After placing the automotive parts in the soaking basket 25, start the first motor 2. Its output power is transmitted to the rotating shaft 21 via the coupling, driving the rotating shaft 21 to rotate slowly. The rotating shaft 21 drives the telescopic rods 22 at both ends to rotate synchronously. During the rotation, the telescopic rods 22 continuously contract and extend, causing the soaking basket 25 and its internal parts to make a circular motion along the guide rail 23.

[0032] When the soaking basket 25 rotates to its highest point, it just detaches from the cleaning fluid surface. At this moment, the pre-set high-pressure nozzle 13 is activated, drawing cleaning fluid from the rinsing tank 1 through the water pipe 1302. The high-pressure nozzle 13 then performs a high-pressure rinse on the soaking basket 25 and the pre-treated oil-softened parts inside. Thanks to the thorough soaking in the hot cleaning fluid beforehand, the softened oil on the surface of the parts can be efficiently rinsed away by the high-pressure nozzle 13, achieving an automated and efficient rinsing process.

[0033] Due to significant differences in the structure and size of automotive parts, when multiple parts are placed together in the soaking basket 25 to improve rinsing efficiency, parts are prone to stacking and adsorption. Stacking causes parts to come into close contact in certain areas, making it difficult for these areas to be fully wetted by the cleaning fluid during the pretreatment process in the rinsing tank 1, resulting in poor softening of oil stains. At the same time, the downward rinsing design of the high-pressure nozzle 13 means that when the soaking basket 25 is rotated to its highest point, the parts on the lower side inside cannot be effectively rinsed, resulting in incomplete cleaning.

[0034] Therefore, a rotation mechanism needs to be designed to ensure that the components inside the soaking basket 25 rotate fully during the pretreatment and rinsing stages, so as to ensure that each component can fully contact the cleaning fluid and be rinsed from all directions by the high-pressure nozzle 13, thereby ensuring cleaning quality and efficiency.

[0035] like Figure 3 As shown, specifically, gear rings 24 are fixedly connected to the symmetrically distributed guide rails 23, and gears 28 are fixedly connected to both ends of each soaking basket 25. The gears 28 mesh with the adjacent gear rings 24 to form a gear 28 transmission system. When the rotating shaft 21 drives the soaking basket 25 to rotate along the guide rail 23 via the telescopic rod 22, the movement of the soaking basket 25 drives the gear 28 to rotate. Based on the meshing transmission principle of the gear 28 and the gear ring 24, the gear ring 24 causes the soaking basket 25 to rotate autonomously around the fixed axis, thereby realizing the synchronous rotation of the components inside the soaking basket 25.

[0036] When the first motor 2 drives the rotating shaft 21 to rotate, and the telescopic rod 22 drives the soaking basket 25 to move in a circular motion along the guide rail 23, the gears 28 at both ends of the soaking basket 25 continuously mesh with the gear ring 24 on the guide rail 23. During the movement, the gears 28 rotate due to the meshing force of the gear ring 24, which in turn drives the soaking basket 25 to rotate around its fixed axis, causing the internal components to rotate accordingly. During the rotation, the stacked and adsorbed state of the components is broken, and they are evenly dispersed, ensuring that the cleaning solution can fully wet every surface, significantly improving the oil softening effect in the pretreatment stage.

[0037] When the soaking basket 25 rotates to its highest point and the high-pressure nozzle 13 starts rinsing, all parts of the rotating accessories are fully exposed, achieving comprehensive and efficient rinsing by the high-pressure nozzle 13. This effectively solves the problem of blind spots in cleaning caused by the stacking of accessories and the position of the nozzle, ensuring the quality of cleaning.

[0038] To improve the pretreatment and rinsing effect of automotive parts, the soaking basket 25 needs to rotate during operation. However, the soaking basket 25 is usually an open structure. When stationary or not rotating, it relies on its own weight and the weight of the parts to keep the opening facing upwards, ensuring that the parts do not fall off. But when the soaking basket 25 rotates, the original gravity constraint fails, and the internal parts are very likely to fall out of the opening into the rinsing tank 1. This can not only cause parts to be lost or damaged, but may also interfere with the normal operation of the rinsing process and even cause equipment failure.

[0039] Therefore, a reliable flip-top mechanism needs to be designed to achieve precise control over the opening and closing state of the soaking basket 25. This will facilitate the placement and removal of accessories while ensuring that the accessories are securely stored during the rotation of the soaking basket 25, thus guaranteeing the safety and continuity of the cleaning process.

[0040] like Figure 3 As shown, specifically, each soaking basket 25 is rotatably connected to a rotating cover 26 for controlling the opening and closing of the opening; each soaking basket 25 is slidably connected to a locking member 27, which is connected to a symmetrically distributed first spring 271 between itself and the adjacent soaking basket 25, with the first spring 271 wound around the locking member 27. Each rotating cover 26 has symmetrically distributed insertion holes on the side near the locking member 27, and the locking member 27 engages with the insertion holes to lock the position of the rotating cover 26.

[0041] When placing the automotive parts, pull the locking piece 27 outward to overcome the elastic force of the first spring 271 and disengage it from the insertion hole of the rotating cover 26. The first spring 271 deforms and stores elastic potential energy. Then, flip the rotating cover 26 upward to open it and evenly place the parts in the soaking basket 25.

[0042] After placement, flip the rotating cover 26 downwards to close it, release the locking member 27. Under the elastic force of the first spring 271, the locking member 27 moves in the opposite direction to reset and inserts into the socket of the rotating cover 26, forming a mechanical lock and firmly fixing the rotating cover 26 to the soaking basket 25. During the subsequent rotation of the soaking basket 25, this locking structure can effectively prevent the rotating cover 26 from opening accidentally, ensuring that internal parts will not fall off and guaranteeing the safe and orderly progress of the cleaning process.

[0043] When the soaking basket 25 rotates under the drive of the guide rail 23 and gear 28 transmission system, the internal components are subjected to centrifugal force and rotational inertia, and tumble freely within the enclosed space formed by the soaking basket 25 and the rotating cover 26. This dynamic process effectively separates the components that are attached to each other, allowing the cleaning fluid to fully wet the surface of the components, significantly improving the pretreatment effect of softening oil stains.

[0044] When the soaking basket 25 rotates to its highest point, the high-pressure nozzle 13 is activated, fully exposing all parts of the loose and tumbling components. The high-pressure water flow can then thoroughly rinse the components 360° without any dead angles, completely removing the softened oil stains and significantly improving cleaning efficiency and cleanliness.

[0045] In the process of washing oil stains on automotive parts, the oil stains flushed by the high-pressure nozzles 13 inside the washing tank 1 float to the surface of the cleaning fluid and then rapidly spread within the tank. These spread oil stains easily re-adhere to the surface of the parts with the water flow, causing secondary pollution and severely affecting the cleaning effect. Furthermore, conventional methods are insufficient to completely scrape off and collect these floating oil stains, resulting in oil residue inside the tank. Long-term accumulation of this residue can also affect the normal operating efficiency and service life of the washing tank 1. Therefore, it is necessary to design an efficient oil removal mechanism to thoroughly remove and properly collect floating oil stains, ensuring the cleanliness and efficiency of the washing operation.

[0046] like Figure 4 As shown, specifically, a second motor 3 is installed on the flushing box 1, and its output shaft is fixed to a lead screw 31 through a coupling. The lead screw 31 is rotatably connected to the flushing box 1 to provide power for the oil scraping operation. The lead screw 31 is threadedly connected to an oil scraper 32, which is partially immersed in the cleaning fluid surface to scrape off floating oil. Symmetrically distributed soft blocks 33 are fixed to the oil scraper 32. The elastic deformation characteristics of the soft blocks 33 are used to realize the smooth translation of the oil scraper 32.

[0047] When the soaking basket 25 rotates to its highest point and continues to rotate 60°, its height is lower than that of the oil scraper 32. At this point, the second motor 3 is activated. The second motor 3 drives the lead screw 31 to rotate, and through threaded transmission, precisely drives the oil scraper 32 and the soft block 33 to move horizontally to the left along the flushing tank 1. During the translation, the oil scraper 32 and the soft block 33 continuously scrape the oil floating on the surface of the cleaning fluid to the left. When the soft block 33 comes into contact with obstacles such as the guide rail 23 and the gear ring 24, it adapts to the obstacle by its own elasticity, closely conforming to the outline of the obstacle and continuing to move; after passing the obstacle, the soft block 33 quickly returns to its initial state under its own elastic force, continuously carrying out the oil scraping operation.

[0048] The side wall of the rinsing tank 1 has a precisely positioned oil drain port on the side away from the second motor 3. A material extractor 34 is strategically placed at the drain port to extract and transfer oil sludge. A storage container 35 is securely attached to the side wall of the rinsing tank 1, specifically for temporarily storing the discharged oil sludge. It is located directly below the oil outlet of the material extractor 34, ensuring that the oil sludge flows accurately into the storage container 35. This design, through the cooperation of the material extractor 34 and the storage container 35, achieves efficient collection and storage of scraped oil sludge.

[0049] During the oil scraping operation, as the oil scraper 32 and the soft block 33 move to the left, they continuously scrape the floating oil to the left. The deformation characteristics of the soft block 33 are used to adhere to the surface of the obstacle, effectively guiding the oil to gather at the oil outlet and preventing the oil from spreading to the right.

[0050] Once oil accumulates at the drain outlet, the extraction machine 34 is activated to quickly extract the oil from the drain outlet and precisely transport it to the storage container 35 for temporary storage. After the storage container 35 is full, the operator can safely remove it from the flushing tank 1, empty the internal oil into a dedicated collection bucket for centralized treatment, and then accurately reinstall the storage container 35 in its original position, thus completing the entire oil collection and treatment process.

[0051] Example 2: In the oil stain washing operation of automotive parts, although the existing oil removal mechanism can scrape off floating oil stains, the oil stains tend to adhere to the inner wall of the washing tank 1, the guide rail 23, and the area near the water surface of the toothed ring 24 due to the oil stains' tendency to stick to the walls. During the oil scraping process, when the scraper 32 and the soft block 33 encounter obstacles such as the guide rail 23 and the toothed ring 24, the soft block 33 undergoes adaptive deformation, making it impossible to maintain a tight fit with the inner wall of the washing tank 1. This causes the oil stains to spread to the right from the gap between the soft block 33 and the inner wall, resulting in incomplete oil scraping and difficulty in completely collecting the oil stains at the drain port. Therefore, it is necessary to design an oil stain guiding and concentrating mechanism to guide the oil stains adhering to the inner wall of the washing tank 1 and the dead corners of the parts to the middle of the liquid surface, so as to achieve thorough removal of the oil stains in conjunction with the oil scraping device.

[0052] like Figure 5 and Figure 6 As shown, specifically, the oil scraper 32 is slidably connected to the striking member 41, and the two are elastically connected by a second spring 42, which is wound around the striking member 41; the striking member 41 is fixedly connected to the squeezing member 4, and the squeezing member 4 can slide horizontally on the flushing tank 1; the flushing tank 1 is fixedly connected to symmetrically distributed wedge blocks 43, whose surfaces are provided with inclined surfaces. By squeezing and cooperating with the inclined surfaces of the squeezing member 4, the striking member 41 is driven to move up and down reciprocatingly, thereby striking the surface of the cleaning liquid, and thus guiding the oil stains near the inner wall of the flushing tank 1 to concentrate in the middle, so that the oil scraper 32 and the soft block 33 can thoroughly scrape them off.

[0053] When the oil scraper 32 moves to the left under the drive of the second motor 3, the extrusion member 4 and the striking member 41 move to the left synchronously. During the movement, the extrusion member 4 contacts the inclined surface of the wedge block 43 and is subjected to the extrusion action of the inclined surface. The extrusion member 4 drives the striking member 41 to slide upward relative to the oil scraper 32, stretching the second spring 42.

[0054] After the extruder 4 passes the inclined surface of the wedge block 43, under the elastic force of the second spring 42, the striking member 41 quickly drives the extruder 4 to slide downward and reset. As the oil scraper 32 continues to move to the left, the extruder 4 continuously contacts and separates from each wedge block 43, causing the striking member 41 to perform high-frequency up-and-down reciprocating motion.

[0055] When the striking element 41 slides upward, the second spring 42 accumulates elastic potential energy; when it slides downward, it accelerates under the action of potential energy, striking the surface of the cleaning liquid, causing the center of the liquid surface to dip and rebound towards the inner wall of the flushing tank 1. When the striking element 41 moves upward, the liquid near the inner wall quickly gathers towards the center, washing the oil stains adhering to the inner wall of the flushing tank 1, the guide rail 23, and the toothed ring 24 to the center of the liquid surface, so that the oil scraper 32 and the soft block can scrape the oil stains in the center to the left side.

[0056] When the oil scraper 32 and the soft block 33 move to the left and pass the leftmost wedge block 43, the extruder 4 continues to move to the left with the oil scraper 32. At this time, the oil that has been guided to the middle of the liquid surface is intercepted by the oil scraper 32 and the soft block 33 and is successfully gathered at the oil outlet so that the subsequent material extractor 34 can extract and process it.

[0057] After the oil is extracted, the second motor 3 needs to be controlled to drive the lead screw 31 to rotate in the opposite direction, driving the oil scraper 32 to reset to the right. However, since the left wall of the wedge block 43 is vertical, it will block the movement of the squeezing member 4, causing the oil scraper 32 to fail to reset smoothly. If forced to reset, it may cause damage to components such as the squeezing member 4 and the oil scraper 32, or cause the engagement between the striking member 41 and the second spring 42 to fail, affecting subsequent oil cleaning operations. Therefore, a lifting mechanism needs to be designed so that the squeezing member 4 can smoothly pass over the wedge block 43, ensuring the safe and efficient reset of the oil scraper 32 and maintaining the stable operation of the oil removal system of the flushing box 1.

[0058] Specifically, symmetrically distributed fixing members 46 are fixed to the flushing box 1, located directly above the adjacent wedge block 43. The flushing box 1 is rotatably connected to symmetrically distributed movable plates 44 near the oil drain port. Torsion springs 45 connect the movable plates 44 to the flushing box 1, with each torsion spring 45 wound around an adjacent movable plate 44. Each movable plate 44 is inclined, forming a ramp structure with the adjacent fixing members 46 to assist the extruder 4 in passing over the wedge block 43. Through the elastic restoring characteristics of the torsion springs 45 and the rotatable design of the movable plates 44, the extruder 4 is lifted and guided, ensuring that the oil scraper 32 can smoothly return to its original position.

[0059] When the extruder 4 moves to the left along with the scraper 32 and comes into contact with the movable plate 44, the extruder 4 pushes the movable plate 44 to overcome the resistance of the torsion spring 45 and flips it upward, causing the torsion spring 45 to undergo torsional deformation. After the extruder 4 passes the movable plate 44, the movable plate 44 flips downward and resets under the elastic force of the torsion spring 45.

[0060] After the oil is extracted, the second motor 3 drives the lead screw 31 to rotate in the opposite direction, driving the oil scraper 32 to reset to the right. At this time, the inclined movable plate 44 presses against the extruder 4, forcing the extruder 4 to drive the striking member 41 to move upward against the elastic force of the second spring 42, and the second spring 42 is stretched.

[0061] As the oil scraper 32 continues to move to the right, the extruder 4 slides along the movable plate 44 onto the horizontal fixed member 46, and continues to move to the right under the guidance of the fixed member 46. After the extruder 4 passes the fixed member 46, under the elastic force of the second spring 42, the striking member 41 drives the extruder 4 to move downward quickly to reset, ensuring that the oil scraper 32 successfully completes the reset operation.

[0062] After rinsing, remove the parts from the soaking basket 25 in the reverse order of the parts placement. When the cleaning power of the cleaning solution in the rinsing tank 1 decreases, open the drain pipe 11 valve to discharge the waste liquid. After the cleaning solution is drained, remove the collection tank 12, empty the waste residue, and reinstall it in its original position to complete the cleaning solution replacement and waste residue disposal.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
