A lubricating grease filling device

Abstract

This utility model belongs to the technical field of filling equipment, specifically a lubricating grease filling device, including a filling barrel with a support rod fixedly connected to its outer side. By setting up a fixed pipe, an adjusting pipe, a sealing plate, a toothed plate, and gears, during filling, the packaging barrel is placed under the fixed pipe. At this time, the end of the adjusting pipe located inside the filling barrel is higher than the lubricating oil level. A first motor drives the gear to rotate, which in turn drives the toothed plate, sealing plate, and adjusting pipe to move downwards, causing the adjusting pipe to move slightly below the lubricating oil level. At this point, the lubricating oil flows down from the highest point, resulting in a large liquid drop and a fast flow rate, facilitating rapid entry into the packaging barrel for filling. When filling is almost complete, the adjusting pipe is raised above the lubricating oil level, and filling is completed using the lubricating oil remaining inside the fixed pipe and adjusting pipe. This device utilizes the liquid drop difference to increase the lubricating oil flow rate, making filling faster and more convenient, and improving the filling efficiency of the device.

Description

Technical Field

[0001] This utility model relates to the field of filling equipment technology, specifically a lubricating grease filling equipment. Background Technology

[0002] Lubricating grease is a semi-solid lubricant composed of base oil, thickener, and additives. It has the characteristics of strong adhesion, good sealing performance, and high temperature resistance. It reduces mechanical wear by forming a lubricating film on the friction surface, and also has the functions of rust prevention and noise reduction. It is widely used in the lubrication and protection of industrial equipment such as bearings, gears, and chains, as well as automotive parts. In order to facilitate its transportation and packaging, lubricating grease is filled into the inside of the packaging barrel by filling equipment during the production of lubricating grease.

[0003] However, existing lubricating grease filling machines have the problem that after filling, some lubricating grease is easily left on the barrel wall. This part of the lubricating grease is difficult to drain and fill. In addition, the filling pipe is mostly fixed at the bottom of the filling barrel. Because it is close to the packaging barrel, the flow rate of lubricating oil is relatively fixed and slow, which affects the filling efficiency of the device. Therefore, a lubricating grease filling device is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A lubricating grease filling device according to this utility model includes a filling barrel, a support rod fixedly connected to the outside of the filling barrel, a fixed pipe fixedly connected to the outside of the filling barrel, an adjusting pipe slidably connected to the inside of the fixed pipe, a sealing plate fixedly connected to the outside of the adjusting pipe, the sealing plate and the filling barrel being slidably connected, a toothed plate fixedly connected to the outside of the sealing plate, a gear meshing with the outside of the toothed plate, and a first motor fixedly connected to the upper side of the filling barrel, the output section of the first motor being fixedly connected to the gear; this step, by setting up the fixed pipe, adjusting pipe, sealing plate, toothed plate, and gear, during filling, the package... The container is placed under the fixed pipe. At this time, the end of the regulating pipe inside the filling container is higher than the lubricating oil level. The first motor drives the gear to rotate, which in turn drives the toothed plate, sealing plate, and regulating pipe to move down. This causes the regulating pipe to move down to a position slightly below the lubricating oil level. At this point, the lubricating oil will flow down from the highest point. The large drop in liquid level and the fast flow rate facilitate rapid entry into the inner side of the packaging container for filling. When filling is about to be completed, the regulating pipe is raised to a position higher than the lubricating oil level. The filling is completed by relying on the lubricating oil remaining inside the fixed pipe and the regulating pipe. During filling, the flow rate of the lubricating oil can be increased by relying on the drop in liquid level, making filling faster and more convenient, and improving the filling efficiency of the device.

[0006] Preferably, a hydraulic cylinder is fixedly connected to the upper side of the filling barrel, and a piston plate is fixedly connected to the output end of the hydraulic cylinder. The piston plate and the filling barrel work together. This step, by setting up the hydraulic cylinder and piston plate, ensures that when the filling process is nearing completion, the operator no longer needs to add lubricating oil to the inside of the filling barrel. When the lubricating oil remaining inside the filling barrel needs to be discharged, the adjusting pipe can be moved to the bottom of the filling barrel by moving one end of the adjusting pipe inside the filling barrel. Then, the hydraulic cylinder drives the piston plate to move, and the piston plate presses against the inner wall of the filling barrel, making it easier to scrape off the lubricating oil adhering to the inside of the filling barrel. This causes the lubricating oil to accumulate at the bottom of the inside of the filling barrel, and with the compression of the piston plate, the lubricating oil is discharged from the adjusting pipe, thereby reducing the residual accumulation of lubricating oil inside the device and improving the stability of the filling process.

[0007] Preferably, a second motor is fixedly connected to the outside of the fixed tube, and a rotating plate is fixedly connected to the output end of the second motor. A through groove is formed on the surface of the rotating plate. This step, by setting up the second motor, the rotating plate, and the through groove, allows the rotating plate to rotate when the device is filling. The rotating plate then aligns the through groove with the lower opening of the fixed tube, facilitating the discharge of lubricating oil. After the device is filled, the rotating plate can be moved by the second motor, causing the through groove to be misaligned with the fixed tube, making it difficult for lubricating oil to drain. This makes it easier for the user to replace the packaging container, as lubricating oil is less likely to drip from the inside of the fixed tube, thereby reducing lubricating oil loss during filling and improving the practicality of the device.

[0008] Preferably, limiting plates are fixedly connected to both the upper and lower sides of the sealing plate, and the limiting plates are used in conjunction with the filling barrel. This step, by setting the limiting plates, ensures that when the sealing plate moves to its maximum position, it moves to contact the upper and lower sides of the filling barrel. The filling barrel blocks the limiting plates, making it difficult for the sealing plate to move further down or up, thereby limiting the range of movement of the sealing plate and improving the stability of the device.

[0009] Preferably, a support plate is fixedly connected to one side of the support rods that are close to each other, and a conveyor belt assembly is provided on the inner side of the support plate. This step, by setting up the support plate and the conveyor belt assembly, allows the packaging barrel to be placed on the upper side of the conveyor belt assembly during the filling process. The packaging barrel is then transported by the rotation of the conveyor belt assembly, so as to move the packaging barrel closer to or away from the lower opening of the fixed tube. This facilitates the movement of unfilled and filled packaging barrels by the device, eliminating the need for the user to replace the packaging barrels and improving the convenience of using the device.

[0010] Preferably, a mounting plate is fixedly connected to the outer side of the support plate, and a mounting groove is provided on the surface of the mounting plate. By setting up the mounting plate and the mounting groove, the device can be installed and fixed by screwing bolts into the mounting groove and the mounting location before use, thereby improving the convenience of device installation.

[0011] The advantages of this utility model are:

[0012] 1. This utility model, by setting up a fixed pipe, an adjusting pipe, a sealing plate, a toothed plate, and a gear, allows the packaging barrel to be placed under the fixed pipe during filling. At this time, the end of the adjusting pipe located inside the filling barrel is higher than the lubricating oil level. The first motor drives the gear to rotate, which in turn drives the toothed plate, the sealing plate, and the adjusting pipe to move down, so that the adjusting pipe moves down to slightly below the lubricating oil level. At this time, the lubricating oil will flow down from the highest point, with a large liquid drop and a fast flow rate, which facilitates rapid entry into the inside of the packaging barrel for filling. When filling is about to be completed, the adjusting pipe is raised to be higher than the lubricating oil level, and the filling is completed by relying on the lubricating oil remaining inside the fixed pipe and the adjusting pipe. During filling, the lubricating oil flow rate can be increased by relying on the liquid drop, making filling faster and more convenient, and improving the filling efficiency of the device.

[0013] 2. This utility model, by setting up a hydraulic cylinder and piston plate, allows the operator to stop adding lubricating oil to the inside of the filling barrel when the filling process is nearing completion. When the residual lubricating oil inside the filling barrel needs to be discharged, the adjusting pipe can be moved from one end inside the filling barrel to the bottom. Then, the hydraulic cylinder drives the piston plate to move, and the piston plate presses against the inner wall of the filling barrel, making it easier to scrape off the lubricating oil adhering to the inside of the filling barrel. This causes the lubricating oil to accumulate at the bottom of the inside of the filling barrel, and with the compression of the piston plate, the lubricating oil is discharged from the adjusting pipe. This reduces the residual accumulation of lubricating oil inside the device and improves the stability of the filling process. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] Specific implementation examples are given below.

[0023] Please see Figures 1 to 5 As shown, a lubricating grease filling device includes a filling barrel 1. A support rod 2 is fixedly connected to the outside of the filling barrel 1. A fixing pipe 3 is fixedly connected to the outside of the filling barrel 1. An adjusting pipe 4 is slidably connected to the inside of the fixing pipe 3. A sealing plate 5 is fixedly connected to the outside of the adjusting pipe 4. The sealing plate 5 and the filling barrel 1 are slidably connected. A toothed plate 6 is fixedly connected to the outside of the sealing plate 5. A gear 7 meshes with the outside of the toothed plate 6. A first motor 8 is fixedly connected to the upper side of the filling barrel 1. The output section of the first motor 8 is fixedly connected to the gear 7. This step, by setting up the fixing pipe 3, adjusting pipe 4, sealing plate 5, toothed plate 6, and gear 7, allows the packaging barrel to be placed on the fixing pipe during filling. 3. At this time, the end of the regulating pipe 4 located inside the filling barrel 1 is higher than the lubricating oil level. The first motor 8 drives the gear 7 to rotate, and the gear 7 drives the toothed plate 6, the sealing plate 5 and the regulating pipe 4 to move down, so that the regulating pipe 4 moves down to slightly below the lubricating oil level. At this time, the lubricating oil will flow down from the highest point. The liquid drop is large and the flow rate is fast, which facilitates the rapid entry into the inner side of the packaging barrel for filling. When the filling is about to be completed, the regulating pipe 4 is raised to be higher than the lubricating oil level. The filling can be completed by relying on the fixed pipe 3 and the lubricating oil remaining inside the regulating pipe 4. During the filling, the flow rate of the lubricating oil can be increased by relying on the liquid drop, making the filling faster and more convenient, and improving the filling efficiency of the device.

[0024] Furthermore, such as Figure 1 and Figure 2 As shown, a hydraulic cylinder 9 is fixedly connected to the upper side of the filling barrel 1, and a piston plate 10 is fixedly connected to the output end of the hydraulic cylinder 9. The piston plate 10 and the filling barrel 1 work together. This step, by setting up the hydraulic cylinder 9 and the piston plate 10, ensures that when the filling process is nearing completion, the operator no longer needs to add lubricating oil to the inside of the filling barrel 1. When the residual lubricating oil inside the filling barrel 1 needs to be discharged, the adjusting pipe 4 can be moved from one end inside the filling barrel 1 to the bottom inside the filling barrel 1. Then, the hydraulic cylinder 9 drives the piston plate 10 to move, so that the piston plate 10 is pressed against the inner wall of the filling barrel 1, which facilitates the scraping off of the lubricating oil adhering to the inside of the filling barrel 1. This causes the lubricating oil to accumulate at the bottom inside the filling barrel 1, and with the squeezing of the piston plate 10, the lubricating oil is discharged from the adjusting pipe 4, thereby reducing the residual accumulation of lubricating oil inside the device and improving the stability of the filling process.

[0025] Furthermore, such as Figure 2 and Figure 5 As shown, a second motor 11 is fixedly connected to the outside of the fixed tube 3, and a rotating plate 12 is fixedly connected to the output end of the second motor 11. A through groove 101 is provided on the surface of the rotating plate 12. This step, by setting the second motor 11, the rotating plate 12, and the through groove 101, allows the rotating plate 12 to rotate when the device is filling. The rotating plate 12 drives the through groove 101 to align with the lower opening of the fixed tube 3, thus facilitating the discharge of lubricating oil from the device. After the device is filled, the rotating plate 12 can be moved by the second motor 11, causing the through groove 101 to be misaligned with the fixed tube 3, making it difficult for lubricating oil to be discharged. This makes it more difficult for lubricating oil to drip from the inside of the fixed tube 3 when the user changes the packaging barrel, thereby reducing the loss of lubricating oil during filling and improving the practicality of the device.

[0026] Furthermore, such as Figure 2 and Figure 3 As shown, limiting plates 13 are fixedly connected to both the upper and lower sides of the sealing plate 5. The limiting plates 13 are used in conjunction with the filling barrel 1. By setting the limiting plates 13, when the sealing plate 5 moves up and down to its maximum position, the limiting plates 13 move to contact the upper and lower sides of the filling barrel 1. The filling barrel 1 blocks the limiting plates 13, making it difficult for the sealing plate 5 to move further down or up. This limits the range of movement of the sealing plate 5 and improves the stability of the device.

[0027] Furthermore, such as Figure 1As shown, a support plate 14 is fixedly connected to one side of the support rods 2 that are close to each other, and a conveyor belt assembly 15 is provided on the inner side of the support plate 14. This step, by setting the support plate 14 and the conveyor belt assembly 15, allows the packaging barrel to be placed on the upper side of the conveyor belt assembly 15 when the device is filling. The packaging barrel is transported by the rotation of the conveyor belt assembly 15, so as to move the packaging barrel closer to or away from the lower opening of the fixed tube 3. This makes it easier for the device to move unfilled packaging barrels and filled packaging barrels without the need for the user to replace the packaging barrels, thus improving the convenience of using the device.

[0028] Furthermore, such as Figure 1 As shown, a mounting plate 16 is fixedly connected to the outer side of the support plate 14, and a mounting groove 17 is provided on the surface of the mounting plate 16. By setting the mounting plate 16 and the mounting groove 17, the device can be installed and fixed by screwing the bolts into the mounting groove 17 and the mounting location before use, which improves the convenience of device installation.

[0029] Working principle: During filling, the packaging barrel is placed on the conveyor belt assembly 15 below the fixed pipe 3. At this time, the end of the adjusting pipe 4 located inside the filling barrel 1 is higher than the lubricating oil level. The first motor 8 drives the gear 7 to rotate, which in turn drives the toothed plate 6, the sealing plate 5, and the adjusting pipe 4 to move downwards. This causes the opening of one end of the adjusting pipe 4 to move down to slightly below the lubricating oil level. At this point, the lubricating oil will flow down from the highest point, resulting in a large drop and fast flow rate, which facilitates rapid entry into the packaging barrel for filling. When filling is about to be completed, the adjusting pipe 4 is raised to be higher than the lubricating oil level, preventing lubricating oil from entering the inner side of the adjusting pipe 4. Filling is completed by relying on the lubricating oil remaining inside the fixed pipe 3 and the adjusting pipe 4. After filling, the second motor 11 drives the rotating plate 12 to move... The device moves by rotating plate 12 to offset the through groove 101 from the fixed pipe 3, making it difficult for lubricating oil to be discharged. Then, the conveyor belt assembly 15 moves the filled and unfilled packaging barrels synchronously for replacement. Then, the filling is carried out again. When the device is about to finish filling, no more lubricating oil is added to the inside of the filling barrel 1. The end of the moving regulating pipe 4 located inside the filling barrel 1 is moved to the bottom of the inside of the filling barrel 1. Then, the hydraulic cylinder 9 drives the piston plate 10 to move. The piston plate 10 is pressed against the inner wall of the filling barrel 1, which makes it easy to scrape off the lubricating oil adhering to the inside of the filling barrel 1. The lubricating oil accumulates at the bottom of the inside of the filling barrel 1. With the squeezing of the piston plate 10, the remaining lubricating oil is discharged from the regulating pipe 4.
