Description

Technical Field

[0001] This utility model relates to the field of filling equipment technology, specifically to an integrated equipment for weighing and filling lubricating oil. Background Technology

[0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. Its main functions include lubrication, auxiliary cooling, rust prevention, cleaning, sealing, and buffering. Filling is the final step in lubricating oil production.

[0003] Based on the above, the inventors have discovered the following problems: the current lubricating oil filling device can only perform basic lubricating oil filling operations and does not have a weighing function. When filling large tanks with lubricating oil, operators cannot obtain weight data in real time during the filling process. In addition, after filling, the large tanks need to be transferred to other weighing equipment for weighing, which increases the handling process and labor costs.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an integrated equipment for weighing and filling lubricating oil, in order to achieve a more practical value. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated device for weighing and filling lubricating oil to solve the problems mentioned in the background art.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A lubricating oil weighing and filling integrated device includes a weighing component, a filling component, and a pushing component. The filling component is disposed outside the weighing component, and the pushing component is disposed inside the filling component. The weighing component is used to weigh the tank during the filling process, and the filling component is used to fill the tank with lubricating oil. The weighing component includes a weighing base with an installation groove on its top surface. A weighing sensor is installed at the bottom of the installation groove, and a weighing platform is connected to the top surface of the weighing sensor. The filling component includes a mounting base with a hollow horizontal column slidingly disposed on its front side. A connecting plate is slidingly disposed on one side of the hollow horizontal column. A cylinder is installed on the top surface of the connecting plate, and the movable end of the cylinder passes through the connecting plate and is connected to a lifting plate. A circular hole is opened inside the lifting plate, and a filling head is connected inside the circular hole. A solenoid valve and a flow meter are installed sequentially from top to bottom on the outside of the filling head.

[0008] Furthermore, the hollow horizontal column has a square groove at one end near the mounting base. An electric slide rail is connected to the front of the mounting base, and an electric slider is slidably connected to the outside of the electric slide rail. The electric slider is located in the square groove, and the outer wall of the electric slider is fixedly connected to the inner wall of the square groove.

[0009] The beneficial effect of adopting the above-mentioned further solution is that, through the combined use of electric slide rail and electric slider, when the electric slide rail and electric slider are working, the hollow horizontal seat slides on the front of the mounting base, adjusting the lateral position of the filling head, which makes it convenient for the filling head to be adjusted according to the different inlet positions of different tanks, thereby carrying out subsequent filling operations.

[0010] Furthermore, the hollow cross column is equipped with a ball screw inside. Both ends of the ball screw are connected to the inner wall of the hollow cross column through bearings. The ball screw is threaded to a slide block. The hollow cross column has a groove on the side near the connecting plate. One end of the slide block extends through the groove to the outside and is fixedly connected to one side of the connecting plate. The outer wall of one end of the slide block slides in fit with the inner wall of the groove. A servo motor is installed at the end of the hollow cross column away from the electric slider. The output end of the servo motor is fixedly connected to the ball screw.

[0011] The beneficial effect of adopting the above-mentioned further solution is that, through the coordinated use of servo motor, ball screw, slide block and slide groove, when the servo motor is working, it is easy to drive the ball screw to rotate, so that the slide block connected to the external thread of the ball screw moves linearly under the sliding cooperation with the slide groove. Since one end of the slide block is connected to the connecting plate, the longitudinal position of the filling head can be adjusted, which makes it convenient for the filling head to be adjusted according to the different inlet positions of different cans, so as to carry out subsequent filling operations.

[0012] Furthermore, an oil cylinder is connected to the top of the mounting base, and a first pressure pump is installed on one side of the outer wall of the oil cylinder. The outlet end of the first pressure pump is connected to a corrugated hose, and the end of the corrugated hose away from the first pressure pump is connected to the filling head. The inlet end of the first pressure pump passes through the oil cylinder and is connected to a connecting pipe. A second pressure pump is installed on the back of the oil cylinder, and the outlet end of the second pressure pump extends through the oil cylinder into the interior.

[0013] The beneficial effect of adopting the above-mentioned further solution is that, by setting up a first pressure pump and a second pressure pump, when the first pressure pump is started, the lubricating oil in the oil cylinder is pumped into the filling head through the connecting pipe and the corrugated hose, and then the filling head fills the hollow tank. By setting up a second pressure pump, the inlet end of the second pressure pump is connected to the external pipe, and one end of the external pipe is connected to the storage container for storing lubricating oil. When the second pressure pump is started, it is convenient to pump lubricating oil into the oil cylinder.

[0014] Furthermore, the top surface of the weighing platform is provided with a hollow tank, the outer wall of the weighing platform is fitted with the inner wall of the mounting groove with a clearance, and the back of the weighing base is provided with a control panel, which is electrically connected to the weighing sensor, flow meter, solenoid valve and pump through wires.

[0015] The beneficial effect of adopting the above-mentioned further solution is that, during the process of filling the hollow tank on the weighing platform with lubricating oil, the overall weight of the hollow tank increases, causing the weighing platform to continuously move downwards into the mounting base. Through the coordinated use of the control panel, weighing sensor, flow meter, solenoid valve, and first pressure pump, the weighing sensor monitors the weight of the tank in real time, the flow meter accurately measures the amount of lubricating oil being filled, the solenoid valve controls the flow of lubricating oil, and the pump controls the delivery of lubricating oil. When the weighing sensor detects that the weight of the tank is continuously rising until it approaches the preset value, the control panel controls the opening of the solenoid valve, causing the opening of the solenoid valve to decrease, and the flow meter displays that the amount of lubricating oil being filled is decreasing. When the weighing sensor detects that the weight of the tank has reached the preset value, the control panel controls the solenoid valve and the first pressure pump to stop working, thus stopping the lubricating oil filling.

[0016] Furthermore, the mounting base has a groove inside, and the pushing assembly includes a push block and a pair of electric telescopic rods. The push block is disposed inside the groove and slides in cooperation with the groove. One side of the push block is arc-shaped. The movable ends of the pair of electric telescopic rods are respectively fixedly connected to one side of the push block. The ends of the pair of electric telescopic rods that are away from the push block both extend through the mounting base to the outside. The outer walls of the pair of electric telescopic rods are respectively fixedly connected to the inner wall of the through hole of the mounting base.

[0017] The beneficial effect of adopting the above-mentioned further solution is that, through the combined use of the electric telescopic rod and the push block, the push block is arc-shaped on the side away from the electric telescopic rod. After the filling is completed and the hollow tank is filled with lubricating oil, the electric telescopic rod is activated to push the push block forward, pushing the hollow tank filled with lubricating oil onto the first belt conveyor.

[0018] Furthermore, a first belt conveyor is installed on the front of the weighing base, and a second belt conveyor is installed on the outer side of the weighing base.

[0019] The beneficial effect of adopting the above-mentioned further scheme is that, through the combined use of the first belt conveyor and the second belt conveyor, the first belt conveyor transports the hollow tank filled with lubricating oil to realize the discharge after filling, and the second belt conveyor transports the hollow tank without lubricating oil to realize the feeding before filling.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: This integrated weighing and filling equipment for lubricating oil first starts the second belt conveyor, which transports the empty hollow tanks without lubricating oil to achieve feeding before filling, so that the hollow tanks are placed on the weighing base. Then, the hollow tanks are manually placed on the weighing platform. According to the position of the inlet of the hollow tank, the electric slide rail and electric slider work, so that the hollow horizontal seat slides on the front of the mounting base, adjusting the lateral position of the filling head. When the servo motor works, it is convenient to drive the ball screw to rotate, so that the slide seat connected to the external thread of the ball screw moves linearly under the sliding cooperation with the slide groove. Since one end of the slide seat is connected to the connecting plate, the longitudinal position of the filling head is adjusted, which is convenient for the filling head to be adjusted according to the different inlet positions of different tanks. Then, the height of the lifting plate is adjusted by the operation of the cylinder. When the lifting plate moves downward, the filling head moves downward, so that the bottom part of the filling head is located in the inlet. When the first pressure pump is started, the lubricating oil in the oil cylinder is pumped out. Oil is pumped into the filling head through connecting pipes and corrugated hoses, and then the filling head fills the hollow tank. During the filling process, the overall weight of the hollow tank on the weighing platform increases, causing the weighing platform to continuously move downwards into the mounting base. The weighing sensor monitors the weight of the tank in real time, the flow meter accurately measures the amount of lubricating oil being filled, the solenoid valve controls the flow of lubricating oil, and the pump controls the delivery of lubricating oil. When the weighing sensor detects that the weight of the tank is rising until it approaches the preset value, the control panel controls the opening of the solenoid valve, causing the opening of the solenoid valve to decrease, and the flow meter displays that the amount of lubricating oil being filled is decreasing. When the weighing sensor detects that the weight of the tank has reached the preset value, the control panel controls the solenoid valve and the first pressure pump to stop working, stopping the lubricating oil filling. After filling is completed and the hollow tank is full of lubricating oil, the electric telescopic rod is activated to push the pusher block forward, pushing the full-filled hollow tank onto the first belt conveyor. The first belt conveyor transports the full-filled hollow tank to achieve discharge after filling. Attached Figure Description

The movable end of the cylinder 25 passes through the connecting plate 24 and is connected to a lifting plate 26. The plate 26 has a circular hole inside, and a filling head 27 is connected inside the circular hole. A solenoid valve 28 and a current meter 29 are installed on the outside of the filling head 27 from top to bottom.

When the lifting plate 26 moves downward, the filling head 27 moves downward, so that the bottom part of the filling head 27 is located in the feed inlet. When the lifting plate 26 moves downward and then upward, the filling head 27 moves upward, so that the bottom part of the filling head 27 is no longer located in the feed inlet. The hollow horizontal seat can move horizontally on the front of the mounting base 21, and the connecting plate 24 can move vertically on one side of the hollow horizontal seat, thereby adjusting the horizontal and vertical positions of the filling head 27.

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 protection scope of the present utility model.

[0030] Please see Figures 1-5This utility model provides a technical solution: a hollow horizontal column 23 has a square groove at one end near the mounting base 21. An electric slide rail 22 is connected to the front of the mounting base 21. An electric slider is slidably connected to the outside of the electric slide rail 22. The electric slider is located within the square groove, and its outer wall is fixedly connected to the inner wall of the square groove.

Through the cooperation of the electric slide rail 22 and the electric slider, when the electric slide rail 22 and the electric slider are working, the hollow horizontal seat slides on the front of the mounting base 21 to adjust the lateral position of the filling head 27. When the servo motor 215 is working, it facilitates the rotation of the ball screw 214, thereby causing the slide 213 connected to the external thread of the ball screw 214 to move linearly under the sliding cooperation with the slide groove. Due to the sliding of the slide 213... The end is connected to the connecting plate 24 to adjust the longitudinal position of the filling head 27, so that the filling head 27 can be adjusted according to the different inlet positions of different tanks, so as to carry out subsequent filling operations. When the first pressure pump 212 is started, the lubricating oil in the oil cylinder 211 is pumped into the filling head 27 through the connecting pipe and the corrugated hose 210, and then the filling head 27 fills the hollow tank. By setting a second pressure pump, the inlet end of the second pressure pump is connected to the external pipe.

[0031] 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 protection scope of the present utility model.

[0032] Please see Figures 1-5 This utility model provides a technical solution: the top surface of the weighing platform 13 is provided with a hollow tank, the outer wall of the weighing platform 13 is clearance-fitted with the inner wall of the mounting groove, a second belt conveyor 5 is installed on the outer side of the weighing seat 11, a control panel is provided on the back of the weighing seat 11, the control panel is electrically connected to the weighing sensor 12, the ammeter 29, the solenoid valve 28 and the first pressure pump 212 through wires, a groove 216 is provided inside the mounting seat 21, the pushing assembly 3 includes a push block 31 and a pair of electric telescopic rods 32, the push block 31 is set inside the groove 216, the push block 31 slides with the groove 216, one side of the push block 31 is arc-shaped, and the movable ends of the pair of electric telescopic rods 32 are... The weighing platform 11 is fixedly connected to one side of the push block 31. A pair of electric telescopic rods 32 extend through the mounting base 21 to the outside at the end away from the push block 31. The outer walls of the pair of electric telescopic rods 32 are fixedly connected to the inner walls of the through holes of the mounting base 21. A first belt conveyor 4 is installed on the front of the weighing platform 11. When the hollow tank on the weighing platform 13 is being filled with lubricating oil, the overall weight of the hollow tank increases, causing the weighing platform 13 to continuously move downward into the mounting base 21. Through the coordinated use of the control panel, the weighing sensor 12, the current meter 29, the solenoid valve 28, and the first pressure pump 212, the weighing sensor 12 monitors the weight of the tank in real time, and the current meter 29 accurately measures the amount of lubricating oil being filled. The solenoid valve 28 controls the flow of lubricating oil, and the pump controls the delivery of lubricating oil. When the load cell 12 detects that the weight of the tank is rising and approaching the preset value, the control panel controls the opening of the solenoid valve 28, causing the opening of the solenoid valve 28 to decrease. The current meter 29 displays that the amount of lubricating oil being filled is decreasing. When the load cell 12 detects that the weight of the tank has reached the preset value, the control panel controls the solenoid valve 28 and the first pressure pump 212 to stop working, stopping the lubricating oil filling. Through the cooperation of the electric telescopic rod 32 and the push block 31, the push block 31 is arc-shaped on the side away from the electric telescopic rod 32. After filling is completed and the hollow tank is full of lubricating oil, the electric telescopic rod 32 is activated to... Pushing block 31 moves forward, pushing the hollow can filled with lubricating oil onto the first belt conveyor 4. Through the cooperation of the first belt conveyor 4 and the second belt conveyor 5, the first belt conveyor 4 transports the hollow can filled with lubricating oil to achieve discharge after filling, and the second belt conveyor 5 transports the hollow can without lubricating oil to achieve feeding before filling. The weighing sensor 12, the first belt conveyor 4 and the second belt conveyor 5 are existing technologies. The working principle of the weighing sensor 12 is referenced in publication number CN216246772U, and the working principle of the first belt conveyor 4 and the second belt conveyor 5 is referenced in publication number CN217625734U.

[0033] Specifically, the working principle of this integrated lubricating oil weighing and filling equipment is as follows: First, the second belt conveyor 5 is started. The second belt conveyor 5 transports the empty hollow canisters (without lubricating oil) to achieve feeding before filling, positioning the hollow canisters on the weighing seat 11. Then, the hollow canisters are manually placed on the weighing platform 13. Based on the position of the hollow canister's inlet, the electric slide rail 22 and electric slider operate, causing the hollow horizontal seat to slide on the front of the mounting base 21, adjusting the lateral position of the filling head 27. When the servo motor 215 operates, it facilitates the driving of the ball screw 21. 4. Rotation causes the slide block 213, connected to the external thread of the ball screw 214, to move linearly under the sliding engagement with the slide groove. Since one end of the slide block 213 is connected to the connecting plate 24, the longitudinal position of the filling head 27 is adjusted, making it convenient for the filling head 27 to be adjusted according to the different inlet positions of different tanks. Then, the height of the lifting plate 26 is adjusted by the operation of the cylinder 25. When the lifting plate 26 moves downward, the filling head 27 moves downward, so that the bottom part of the filling head 27 is located in the inlet. When the first pressure pump 212 is started, the lubricant in the oil cylinder 211 is... Oil is pumped into the filling head 27 through the connecting pipe and corrugated hose 210, and then the filling head 27 fills the hollow tank. During the filling process, the overall weight of the hollow tank on the weighing platform 13 increases, causing the weighing platform 13 to continuously move downwards into the mounting base 21. The load cell 12 monitors the weight of the tank in real time, the ammeter 29 accurately measures the amount of lubricating oil being filled, the solenoid valve 28 controls the flow of lubricating oil, and the pump controls the delivery of lubricating oil. When the load cell 12 detects that the weight of the tank is continuously rising until it approaches the preset value, the control panel controls the solenoid valve. The opening of solenoid valve 28 is reduced, and the current meter 29 shows that the amount of lubricating oil being filled is reduced. When the weighing sensor 12 detects that the weight of the tank has reached the preset value, the control panel controls solenoid valve 28 and the first pressure pump 212 to stop working, stopping the lubricating oil filling. After filling is completed and the hollow tank is full of lubricating oil, the electric telescopic rod 32 is activated to push the push block 31 forward, pushing the hollow tank full of lubricating oil onto the first belt conveyor 4. The first belt conveyor 4 transports the hollow tank full of lubricating oil to achieve discharge after filling.
