Description

Technical Field

[0001] This invention belongs to the field of lubricating oil technology, specifically relating to a lubricating oil production and filling system and filling method. Background Technology

[0002] Lubricating oil is a type of lubricant. It is used between two relatively moving objects to reduce friction caused by contact. Lubricating oil is a technology-intensive product, a complex hydrocarbon compound. It generally consists of two parts: base oil and additives. Base oil is the main component, determining the basic properties of the lubricating oil. Additives compensate for and improve the performance deficiencies of the base oil, imparting certain new properties, and are an important component of lubricating oil. With the development of my country's machinery industry, the quality requirements for lubricating oil are constantly increasing. However, the following problems still exist in the current production and preparation of lubricating oil:

[0003] 1. In the prior art, lubricating oil needs to be filled and packaged after preparation. This is done by inserting a filling nozzle into the packaging can and injecting an appropriate amount of lubricating oil into it. Since lubricating oil has high purity requirements, the packaging can must be clean and free of impurities. Although the packaging can is cleaned and dried before filling, the cleaning process is carried out on a large number of packaging cans at the same time. After the packaging can is cleaned, it needs to be manually handled and loaded during the filling process. Impurities may inevitably enter during this process, affecting the quality of the lubricating oil.

[0004] 2. Currently, during the filling process, the packaging cans need to be placed on the conveyor belt manually. The conveyor belt then transports the packaging cans to be filled directly below the filling nozzle before filling. However, this control method requires workers to monitor the settings for a long time and continuously feed materials. It also requires precise control of the conveyor belt, which consumes a lot of manpower and results in high equipment costs.

[0005] 3. Currently, lubricating oil filling is generally controlled by a solenoid valve. When filling is complete, the solenoid valve is closed, and the lubricating oil remaining in the pipeline will flow out of the nozzle due to gravity. At the same time as filling is finished, the equipment will remove the filling nozzle from the packaging can, causing the lubricating oil flowing from the nozzle to drip onto the packaging can, which will have a great impact on subsequent packaging.

[0022] The lubricating oil production and filling system of the present invention has the following beneficial technical effects:

[0023] 1. In this invention, multiple packaging cans are stacked sequentially in a hopper, and then a pusher plate is used to push the stacked packaging cans in the hopper to the first nozzle. Then, the packaging cans are pushed to the second nozzle by mutual pushing between them, thereby completing the cleaning and filling operations of the packaging cans in sequence. During this process, no worker needs to constantly monitor the equipment or continuously feed materials, saving manpower.

In this invention, by setting a clamping plate on the nozzle plate, when the first nozzle moves downward with the nozzle plate and extends into the packaging can, the clamping plate is controlled to rotate relative to the first nozzle to form a clamping and fixing of the packaging can. Then, during the process of controlling the nozzle plate to move in the horizontal direction, the first nozzle and the clamping plate can be used to clamp and fix the packaging can, and move downstream together with the packaging can to form a cleaning operation of the packaging can before filling, so as to ensure the filling quality of the lubricating oil.

[0025] 3. In this invention, by setting an air inlet and an oil inlet on the slider, the reciprocating movement of the slider relative to the second nozzle can be controlled by the connecting rod, the step, and the slider spring, thereby changing the connection between the second nozzle and the air inlet or the oil inlet, and then filling the second nozzle with lubricating oil or high-pressure gas, completing the filling of the packaging can and blowing the residual lubricating oil in the second nozzle into the packaging can, so that no lubricating oil remains in the nozzle, preventing lubricating oil from dripping onto the outside of the packaging can and keeping the packaging can clean.

[0026] 4.

[0032] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0033] Combination Figures 1 to 5 As shown, the lubricating oil production and filling system of this embodiment includes a hopper 1, a pusher plate 2, a first nozzle 3, and a second nozzle 4. The hopper 1 is vertically mounted on a base plate 5 for stacking multiple packaging cans 6, and the bottom of the hopper 1 has a horizontal outlet. The pusher plate 2 has an L-shaped structure and can reciprocate horizontally relative to the hopper 1. The vertical end of the pusher plate 2 can push the packaging cans 6 in the hopper 1 out of the outlet, while the horizontal end of the pusher plate 2 can support the packaging cans in the hopper 1. The first nozzle 3 is located downstream of the outlet of the hopper 1 and can move vertically into the packaging can 6 and output high-pressure gas into the packaging can 6, thereby blowing away impurities in the packaging can 6. The second nozzle 4 is located downstream of the first nozzle 3 and can move vertically into the packaging can 6 and output lubricating oil into the packaging can 6, thereby completing the lubricating oil filling of the packaging can 6.

[0034] When using the lubricating oil production and filling system of this embodiment for lubricating oil filling operations, multiple packaging cans stacked in the hopper can be pushed sequentially to the first nozzle by a pusher plate. Then, the packaging cans are pushed to the second nozzle by mutual pushing between them, thereby completing the cleaning and filling operations of the packaging cans in sequence. During this process, no worker is required to constantly monitor the equipment or continuously feed materials, saving manpower. Moreover, by pushing the packaging cans in front by the pusher plate, the movement of the packaging cans can be completed without the need for conveyor belt drive or precise sensor control, thus reducing equipment costs.

[0035] In this embodiment, the lubricating oil production and filling system includes a pusher rod 7. The pusher rod 7 is connected to the pusher plate 2 in the horizontal direction to drive the pusher plate 2 to reciprocate in the horizontal direction, thereby continuously pushing out the packaging cans 6 in the hopper 1.

[0036] Combination Figure 1 and Figure 3 As shown, the lubricating oil production and filling system in this embodiment includes a nozzle plate 8 and a clamping plate 9. The nozzle plate 8 is located at the outlet of the hopper 1 and can reciprocate vertically and horizontally, while the first nozzle 3 is fixed vertically on the nozzle plate 8. The clamping plate 9 is disposed on the nozzle plate 8 and can reciprocate relative to the first nozzle 3, and together with the first nozzle 3 extending into the packaging can 6, it clamps and fixes the packaging can 6.

[0037] At this point, as the first nozzle moves downward with the nozzle plate and extends into the packaging can, the clamping plate is controlled to rotate relative to the first nozzle to clamp and fix the packaging can. Then, as the nozzle plate moves horizontally, the clamping and fixing of the packaging can by the first nozzle and the clamping plate can be used to move downstream together with the packaging can, forming a cleaning operation of the packaging can before filling, ensuring the filling quality of the lubricating oil.

[0038] In this embodiment, the first nozzle and the nozzle plate adopt an integrated structure design. Of course, in other embodiments, the first nozzle and the nozzle plate can also be connected separately and detachably, for example, by using a threaded connection, so as to facilitate quick disassembly and replacement of the first nozzle.

[0039] Furthermore, in this embodiment, the lubricating oil production and filling system includes a piston cylinder 10, a first one-way valve 11, and a second one-way valve 12, and the first nozzle 3 adopts a hollow piston rod structure. The piston cylinder 10 is vertically connected to the nozzle plate 8 in a sliding manner, and the upper end of the first nozzle 3 is the piston end located within the piston cylinder 10. The first one-way valve 11 is connected to the top of the piston cylinder 10 and is used to unidirectionally introduce outside air into the piston cylinder 10. The second one-way valve 12 is connected to the first nozzle 3 and is used to unidirectionally introduce high-pressure gas from the piston cylinder 10 into the first nozzle 3, which then outputs high-pressure gas into the packaging tank 6.

[0040] At this time, by controlling the reciprocating movement of the piston cylinder relative to the nozzle plate, that is, the reciprocating movement of the piston cylinder relative to the first nozzle, the outside air is continuously introduced into the piston cylinder, and then compressed by the piston cylinder and the first nozzle to enter the first nozzle through the second one-way valve, thus achieving the effect of inputting high-pressure gas into the packaging can.

[0041] In this embodiment, the lubricating oil production and filling system is equipped with a piston rod 13. The piston rod 13 is arranged vertically between the piston cylinder 10 and the nozzle plate 8 as a driving element to drive the piston cylinder 10 to reciprocate vertically relative to the nozzle plate 8.

[0042] Combination Figure 3 and Figure 4 As shown, the lubricating oil production and filling system of this embodiment also includes a clamping rod 14, a clamping rod spring 15, a control plate 16, and a control spring 17. The clamping rod 14 is slidably connected to the nozzle plate 8 in the vertical direction and is located below the piston cylinder 10. The clamping rod spring 15 is located between the clamping rod 14 and the nozzle plate 8 to drive the clamping rod 14 to move upward. At the same time, the clamping plate 9 adopts an L-shaped structure, and the bent position of the clamping plate 9 is rotatably connected to the nozzle plate 8. The horizontal end of the clamping plate 9 is movably connected to the lower end of the clamping rod 14 through a sliding groove and a sliding pin. The outer circumference of the clamping rod 14 is provided with a positioning groove 18. The control plate 16 is slidably connected to the nozzle plate 8 in the horizontal direction. The control spring 17 is connected to the control plate 16 to drive the control plate 16 to move horizontally to insert into the positioning groove 18, so that the vertical end of the clamping plate 9 forms and remains in a clamping and fixed state with the first nozzle 3 for the packaging can 6.

[0043] By setting a clamping rod connected to a clamping spring, and using a sliding groove and a sliding pin to form a movable connection between the clamping rod and the clamping plate, the clamping plate can be rotated by controlling the piston cylinder to move downwards until it contacts the clamping rod and overcomes the clamping spring, thus gradually forming a clamping and fixing of the first nozzle onto the packaging can. When the positioning groove of the clamping rod moves to align with the control plate, the control spring drives the control plate to insert into the positioning groove, thus fixing the clamping plate in the clamping and fixing state with the first nozzle onto the packaging can, completing the clamping and fixing of the clamping plate and the first nozzle onto the packaging can. Conversely, when the piston cylinder moves away from the clamping plate and drives the control plate to overcome the control plate spring and move in the opposite direction out of the positioning groove, the positioning restriction of the clamping rod can be released, and the clamping rod can be driven to move upwards, thereby rotating the clamping plate to release the clamping and fixing of the packaging can.

[0044] Combination Figure 1 As shown, the lubricating oil production and filling system of this embodiment also includes a side plate 19, a side plate spring 20, a step 21, and a positioning plate 22. The side plate 19 is connected to the nozzle plate 8 via a side plate electric rod 33, driving the nozzle plate 8 to reciprocate vertically with respect to the first nozzle 3. The side plate spring 20 is connected to the side plate 19, driving the side plate 19 to move the nozzle plate 8 towards the material hopper 1. The step 21 is located downstream of the second nozzle 4 and can contact the control plate 16, which has moved to a position below the second nozzle 4, driving the control plate 16 to move horizontally against the control spring 17, thereby unlocking the clamping rod 14. The positioning plate 22 is located above the second nozzle 4 and can reciprocate vertically to position the side plate 19 at the contact point between the control plate 16 and the step 21.

[0045] At this time, with the clamping plate and the first nozzle holding the packaging can in place, the push plate pushes the packaging can, allowing it to move towards the position below the second nozzle by overcoming the side plate spring through the nozzle plate and side plate. When the side plate moves to the point where it connects with the positioning plate and the positioning plate fixes the side plate in position, the control plate also contacts the boss and moves to release the clamping rod by overcoming the control plate spring. This allows the first nozzle to be controlled to move upward and be removed from the packaging can.

[0046] Specifically, in the lubricating oil production and filling system of this embodiment, a drive motor 23, a connecting rod 24, and a positioning spring 25 are also provided. The connecting rod 24 is vertically positioned and connected to the second nozzle 4. The output shaft of the drive motor 23 is connected to the connecting rod 24, driving the connecting rod 24 to move the second nozzle 4 vertically in a reciprocating motion. The positioning spring 25 is connected to the positioning plate 22, driving the positioning plate 22 downwards to horizontally restrict the side plate 19. The connecting rod 24 can move upwards to drive the positioning plate 22 to overcome the positioning spring 25 and move upwards, thereby releasing the horizontal restriction on the side plate 19. In this embodiment, the connecting rod is a gear-type rod, and the output shaft of the drive motor is meshed with the connecting rod through a gear to drive the connecting rod to reciprocate vertically.

[0047] At this point, the drive motor can drive the connecting rod to move back and forth in the vertical direction, thereby cooperating with the positioning spring to control the positioning plate to move back and forth in the vertical direction, achieving the positioning plate's control purpose for positioning the side plate.

[0048] Combination Figure 1 and Figure 5 As shown, the lubricating oil production and filling system of this embodiment also includes a slider 26 and a slider spring 27. The slider 26 has an air inlet 28 and an oil inlet 29, and is vertically slidably fitted onto the outside of the second nozzle 4. The slider spring 27 is connected to the slider 26 to drive the slider 26 relative to the second nozzle 4 to move until the air inlet 28 connects with the inlet of the second nozzle 4. Simultaneously, the slider 26 can be driven downwards by the connecting rod 24 to contact the step 21, thus overcoming the movement of the slider spring 27 to the oil inlet 29 to connect with the inlet of the second nozzle 4.

[0049] At this point, by setting an air inlet and an oil inlet on the slider, the reciprocating movement of the slider relative to the second nozzle can be controlled by the connecting rod, the step, and the slider spring. This changes the connection between the second nozzle and the air inlet or the oil inlet, thereby filling the second nozzle with lubricating oil or high-pressure gas. This completes the filling of the packaging can and blows the residual lubricating oil in the second nozzle into the packaging can, ensuring that no lubricating oil remains in the nozzle and preventing lubricating oil from dripping onto the outside of the packaging can, thus keeping the packaging can clean.

[0050] In this embodiment, a hose connects the air inlet to the piston cylinder, allowing the piston cylinder to output high-pressure gas to the air inlet, thus cleaning residual lubricating oil in the second nozzle. Specifically, a third one-way valve 30 and a fourth one-way valve 31 are provided on the side of the piston cylinder 10 away from the first one-way valve 11. The third one-way valve 30 is used to unidirectionally introduce external gas into the piston cylinder 10, and the fourth one-way valve 31 is used to unidirectionally lead the high-pressure gas in the piston cylinder 10 to the second nozzle 4. Simultaneously, an exhaust port 34 is provided on the second nozzle 4. When the oil inlet 29 is connected to the inlet of the second nozzle 4, the air inlet 28 is connected to the exhaust port 34, releasing the high-pressure gas into the external atmosphere.

[0051] At this point, high-pressure gas can be output to the second nozzle from the piston cylinder without affecting the output of high-pressure gas to the first nozzle. This improves the utilization rate of the piston cylinder, reduces the number of power components, and lowers equipment costs.

[0052] In addition, combined Figure 3 As shown, the lubricating oil production and filling system in this embodiment is also provided with a cover plate 32. The cover plate 32 is rotatably connected to the first nozzle 3, and can be fastened to the filling port of the packaging can 6 and rotated to open the filling port of the packaging can 6.

[0053] At this point, after the first nozzle is inserted into the packaging can, the cover plate can rotate under its own weight to close the filling port of the packaging can. After the first nozzle fills the packaging can with high-pressure gas, the cover plate can rotate to the open state under the action of the high-pressure gas, thereby blowing out the impurities in the packaging can smoothly. Furthermore, as the packaging can moves towards the second nozzle, the cover plate can maintain the closing position on the filling port of the packaging can, ensuring the cleanliness of the packaging can.

[0054] Furthermore, in the lubricating oil production and filling system of this embodiment, two first nozzles and two second nozzles are respectively provided. The vent holes of the two second nozzles are connected by an auxiliary pipe, thereby enabling simultaneous cleaning and filling operations on two packaging cans, improving the filling efficiency of lubricating oil. Of course, in other embodiments, depending on the design and usage environment, the number of first and second nozzles can be adjusted to achieve different filling effects.

[0055] Combination Figures 1 to 5 As shown, the lubricating oil is filled using the lubricating oil production and filling system of this embodiment. The specific steps include:

[0056] Step S1, feeding: Stack multiple packaging cans in the hopper in sequence.

[0057] Specifically, multiple packaging cans 6 used for filling lubricating oil are stacked sequentially into the silo 1.

[0058] Step S2, moving the packaging can: control the pusher plate to move horizontally, pushing the packaging can at the outlet position to the position below the first nozzle; control the pusher plate to retract, so that the next packaging can falls to the position corresponding to the outlet.

[0059] Specifically, firstly, the pusher rod 7 is extended, causing the pusher plate 2 to push the packaging can 6 corresponding to the outlet of the hopper 1 out of the hopper 1 to a position below the first nozzle 3 near the hopper 1. Next, the pusher rod 7 is retracted, causing the pusher plate 2 to move in the opposite direction into the hopper 1, causing the packaging can 6 in the hopper 1 to fall to the outlet position of the hopper 1. Then, the pusher rod 7 is extended again, causing the pusher plate 2 to push the packaging can 6 corresponding to the outlet of the hopper 1 out of the hopper 1 to a position below the first nozzle 3 near the hopper 1. At the same time, the packaging can 6 that has already been pushed out of the hopper 1 continues to push downstream, including pushing the packaging can 6 to a position below the first nozzle 3 away from the hopper 1, so that a packaging can 6 is placed below each of the two first nozzles 3.

[0060] Step S3, cleaning the packaging can: control the nozzle plate to move downwards and insert the first nozzle into the packaging can; control the first nozzle to output high-pressure gas into the packaging can to blow out the impurities in the packaging can.

[0061] Specifically, firstly, the control side plate lever 33 extends, causing the nozzle plate 8 to move downwards, leading the first nozzle 3 into the packaging can 6, while simultaneously causing the cover plate 32 to close onto the filling opening of the packaging can 6. Next, the control piston lever 13 retracts, causing the piston cylinder 10 to move downwards relative to the first nozzle 3. On one hand, high-pressure gas is injected into the first nozzle 3 through the first one-way valve 11 and the second one-way valve 12, allowing the high-pressure gas to enter the packaging can 6 and perform a cleaning operation on the inside of the packaging can 6. On the other hand, the piston cylinder 10 moves to contact the clamping rod 14 and drives the clamping rod 14 to move downwards against the clamping rod spring 15, causing the clamping plate 9 to rotate to clamp and fix the packaging can 6 with the first nozzle 3. At the same time, the positioning groove 18 is aligned with the control plate 16 in the horizontal direction, causing the control plate 16 to move under the action of the control spring 17 to insert into the positioning groove 18, thereby fixing the position of the clamping rod 14 and keeping the clamping plate 9 and the first nozzle 3 in a clamped and fixed state on the packaging can 6. The number of reciprocating movements and the single stroke of the piston rod 13 can be adjusted according to the size of the cavity of the packaging can 6.

[0062] Step S4, secondary movement of the packaging can: control the push plate to move horizontally, and push the cleaned packaging can under the second nozzle through the packaging can.

[0063] Specifically, firstly, the pusher lever 7 extends, driving the pusher 2 to push the packaging can 6 corresponding to the outlet of the hopper 1 out of the hopper 1 to a position below the first nozzle 3. During this process, the packaging cans 6 are pushed together to the position below the second nozzle 4. During this process, the clamping plate 9 and the first nozzle 3 clamp and fix the packaging can 6. The nozzle plate 8 drives the side plate 19 to move horizontally synchronously with the packaging can 6, overcoming the side plate spring 20. When the side plate 19 moves to the positioning plate 22, the side plate 19 drives the positioning plate 22 to move upward, overcoming the positioning spring 25, through the inclined surface of the positioning plate 22. After the side plate 19 slides past the inclined surface of the positioning plate 22, the positioning plate 22 moves downward under the action of the positioning spring 25, thus restricting the horizontal position of the side plate 19. Figure 1 The right-side movement is restricted, and the control plate 16 moves to contact the step 21, overcoming the control spring 17 and moving out of the positioning groove 18. This causes the clamping rod 14 to move upward under the restoring force of the clamping rod spring 15, rotating the clamping plate 9 to release the clamping fixation on the packaging can 6. Next, the control side plate lever 33 retracts, moving the nozzle plate 8 upward and removing the first nozzle 3 from the packaging can 6. Then, the drive motor 23 is activated, moving the connecting rod 24 upward, moving the second nozzle 4 to contact the positioning plate 22, and causing the positioning plate 22 to move upward against the force of the positioning spring 25 to release the restriction on the side plate 19. Then, under the restoring force of the side plate spring 20, the side plate 19 drives the nozzle plate 8 and the two first nozzles 3 to return to the horizontal position of the hopper 1. During the movement of the packaging can 6 to the position below the second nozzle 4, the cover plate 32 remains closed over the filling opening of the packaging can 6.

[0064] Step S5, filling: Control the second nozzle to move downward into the packaging can, and control the second nozzle to output lubricating oil into the packaging can to complete the filling.

[0065] Specifically, firstly, the drive motor 23 is started, causing the connecting rod 24 to move downwards, which in turn moves the second nozzle 4 and the slider 26 downwards. As the second nozzle 4 enters the packaging can 6, the slider 26 moves to contact the step 21 and, overcoming the slider spring 27, moves upwards relative to the second nozzle 4, connecting the air inlet 28 to the exhaust port 34 and the oil inlet 29 to the inlet of the second nozzle 4. Next, lubricating oil from an external oiling device is introduced into the second nozzle 4 through the oil inlet 29 until the lubricating oil filling of the packaging can 6 is complete. During this process... The high-pressure gas flowing from the piston cylinder 10 to the second nozzle 4 through the fourth one-way valve 31 is discharged to the outside atmosphere through the air inlet 28 and the exhaust port 34. Then, after the filling is completed, the drive motor 23 is controlled to rotate in the opposite direction, and the second nozzle 4 is moved upward through the connecting rod 24 to gradually move out of the packaging can 6. At the same time, the slider 26 moves downward relative to the second nozzle 4 under the restoring force of the slider spring 27, so that the air inlet 28 is connected to the inlet of the second nozzle 4, and the high-pressure gas is delivered to the second nozzle 4 to blow the lubricating oil remaining in the second nozzle 4 into the packaging can 6.

[0066] Step S6, Cyclic operation and packaging: Through the above steps S2-S5, the lubricating oil can be continuously bottled. After the bottled lubricating oil is capped, it is manually packaged to complete the processing of the lubricating oil.
