Description

Technical Field

[0001] The present invention relates to the technical field of lubricating oil canning, and more particularly to a horizontal automatic lubricating oil filling trolley. Background Art

[0002] As a commonly used lubricant, lubricating oil is mainly used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. In addition, lubricating oil also has auxiliary cooling, rust prevention, cleaning, sealing and buffering functions. It has a wide range of applications. Therefore, lubricating oil occupies an important position in real life.

[0003] In order to facilitate the sale of lubricating oil, it is generally filled into bottles or barrels for easy transportation, storage and sale. In the prior art, during the filling process of lubricating oil, a filter is generally added to the filling equipment to filter the lubricating oil from the oil storage tank to ensure the purity of the lubricating oil. However, in actual operation, it is often necessary to fill different types of lubricating oil, and the filling equipment contains the lubricating oil filled previously. Therefore, in order to avoid mixing and cross-contamination of the lubricating oil, the prior art generally uses the lubricating oil to be filled to clean the filling equipment. Although the purity of the lubricating oil is guaranteed to a certain extent, this operation will result in a large amount of lubricating oil waste. Therefore, further improvement is needed.

[0004] After searching, the Chinese patent application number is: CN 201810783062.2, the publication date is: November 20, 2018, and the name of the invention is: a mobile lubricating oil filling device. The application includes a support frame, a universal wheel installed at the bottom of the support frame, a filter device fixed to the support frame, a filling pump, a weighing device and an air pump. The mobile structure can enable the filling equipment to be moved to multiple locations in the factory, making it more convenient and flexible to use. By controlling the valve switch, it can effectively prevent the lubricating oil from mixing with a large amount of air during the process of passing through the filter cartridge, preventing oil droplets from splashing and causing environmental pollution in the factory. At the same time, the air pump can be used to press the residual lubricating oil in the filter cartridge back into the oil inlet pipe through the return oil pipe, and finally flow back to the oil storage tank, realizing the clean recovery of the lubricating oil. In addition, the weighing device can intuitively weigh the filled lubricating oil, which is convenient for statistical management.

[0005] Although the above application uses an air pump to press the residual lubricating oil in the filter cartridge back into the oil inlet pipe through the return oil pipe, so that the lubricating oil flows back to the oil storage tank, thereby realizing the recovery of the lubricating oil, the filter cartridge in this solution is placed vertically, and its residual lubricating oil accumulates at the bottom of the filter screen. At the same time, the filtered impurities also exist at the bottom of the filter screen. During the recovery process, the lubricating oil is filtered by air pressure and the filtered lubricating oil is recovered, but the impurities still exist in the filter cartridge. When the next different type of lubricating oil is filled, the filled lubricating oil will still be contaminated; in addition, impurities continue to accumulate in the filter screen, reducing the working efficiency of the filling device, and it needs to be treated regularly, which is time-consuming and labor-intensive. Summary of the Invention

By passing gas and backwashing liquid into the filter, the lubricating oil remaining in the filter and filtered impurities are discharged along the input branch pipe, which can avoid the filling trolley from causing cross contamination of lubricating oil during the next filling process, and effectively ensure the filling quality of the lubricating oil; in addition, there is no need to regularly clean impurities in the filter, thereby improving work efficiency.

[0020] 3. Beneficial effects

[0021] Compared with the existing known technologies, the technical solution provided by the present invention has the following significant effects:

[0022] (1) A horizontal automatic lubricating oil filling trolley of the present invention has a filter arranged horizontally on the bottom plate, and the tail end of the filter is connected to the air pipe. By introducing gas and backwashing liquid into the filter, the lubricating oil remaining in the filter and the filtered impurities are discharged along the input branch pipe, thereby achieving the cleaning of the filter. This can effectively avoid the cross contamination of lubricating oil caused by the filling trolley during the next filling process, thereby ensuring the filling quality of the lubricating oil. In addition, since the impurities are removed together during the backwashing process, there is little accumulation of impurities in the filter bag, and there is no need to regularly clean the impurities in the filter net, thereby improving the working efficiency of the filling trolley.

[0023] (2) A horizontal automatic lubricating oil filling trolley of the present invention is provided with an arc tube between the air pipe and the filter, and the height of the arc tube is higher than that of the filter. During the filling process of the lubricating oil, the lubricating oil can be effectively prevented from flowing into the air pipe and affecting the subsequent inflation and backwashing operations. In addition, in order to further avoid the occurrence of this problem, a valve six is provided on the arc tube, and the communication between the air pipe and the arc tube is further blocked by the valve six.

[0024] (3) The horizontal automatic lubricating oil filling trolley of the present invention is provided with valves on the corresponding connecting pipes in order to facilitate the control of the filling of lubricating oil and the subsequent backwashing of the filter. The operator can accurately control the opening and closing of each valve during use to achieve the corresponding operation. The whole process is simple, convenient and easy to operate.

[0025] (4) A horizontal automatic lubricating oil filling trolley of the present invention is provided with an oil drain pipe on the delivery pipe, and a valve 5 is provided on the oil drain pipe. When the filter is backwashed, the backwashing liquid and impurities can enter the oil drain pipe along the input branch pipe and the delivery pipe, and be discharged from the oil drain pipe, and the discharged substances are centrally processed; in addition, the backwashing liquid can also enter the delivery pipe along the input branch pipe and then be sent to the oil storage tank, that is, the lubricating oil is sent to its original place; the operator can select different processing methods according to the actual production needs, and the entire operation process is simple, convenient and flexible;

[0026] (5) A horizontal automatic lubricating oil filling trolley of the present invention is designed to facilitate filling of bottles of different sizes.

[0042] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments.

[0043] Example 1

[0044] A horizontal automatic lubricating oil filling cart in this embodiment includes a gear pump 200 and a filter 400 installed on a base plate 100. The gear pump 200 is connected to the filter 400 through a delivery pipe 310. One end of the delivery pipe 310 in this embodiment is connected to the oil storage tank to be filled. The gear pump 200 provides sufficient power for the entire filling process.

[0045] In current filling equipment, the filter is generally placed vertically, with the liquid inlet and outlet of the filter positioned high in and low out, making filtration easier. However, during the filtering process of the lubricating oil, due to the high viscosity of the filtered lubricating oil, about one-half to two-thirds of the liquid remains in the filter bag after each use, making it difficult to clear it out in time. If this liquid remains, it is removed by increasing the filtration time, but this operation greatly reduces work efficiency and is not practical. In addition, when filling a different type of lubricating oil next time, the lubricating oil remaining in the filter will cause cross-contamination of the lubricating oil to be filled, resulting in a decrease in the quality of the lubricating oil.

[0046] In order to avoid this problem, the filter can be backwashed. However, since the filter is placed vertically and the liquid inlet and outlet of the filter are high in and low out, a large amount of backwashing liquid is consumed during the backwashing process, and a lot of time is also consumed, thus greatly reducing work efficiency.

[0047] Combine Figure 1 、 Figure 2 and Figure 3 To address the aforementioned issues, this embodiment employs a filter 400 that is laterally mounted on the base plate 100 and supported by a support frame. The rear end of the filter 400 is connected to an air pipe 511, which is in turn connected to an air pump 510. Air is introduced into the filter 400 through the air pump 510, providing air pressure to the filter 400 and thereby expelling the lubricating oil from the filter 400.

[0048] In addition, the delivery pipe 310 of this embodiment is provided with an input branch pipe 311 and an output branch pipe 312, wherein the input branch pipe 311 is connected to the filter bag 420 inside the front end of the filter 400; the output branch pipe 312 is connected to the space between the filter bag 420 and the outer shell 410 of the filter 400, and the output branch pipe 312 is located at the tail end of the filter 400.

[0049] In this embodiment, a filling head 600 is provided at one end of the delivery pipe 310 close to the output branch pipe 312 .

[0050] When filling operation is required, the lubricating oil is sent to the input branch pipe 311 along the delivery pipe 310 under the action of the gear pump 200, and flows into the filter 400, and is filtered by the filter bag 420 in the filter 400. The lubricating oil after being filtered by the filter bag 420 enters between the filter bag 420 and the housing 410, and is delivered to the filling head 600 through the output branch pipe 312, and the lubricating oil is filled by the filling head 600.

[0051] When different types of lubricating oil need to be filled, air is introduced into the filter 400 through the air pump 510, so that the lubricating oil and impurities remaining in the filter 400 are sent to the delivery pipe 310 along the input branch pipe 311 and discharged from the delivery pipe 310. The next step of lubricating oil filling is carried out.

[0052] It is worth noting that the lubricating oil and impurities discharged along the delivery pipe 310 can be sent to the original oil storage tank, or can be discharged to other tanks through the delivery pipe 310 to facilitate centralized treatment.

[0053] The entire operation is simple and convenient, and the interval between filling different types of lubricating oil is significantly shortened, improving production efficiency. With the continuous development of technology, the degree of mechanization and automation is increasing, and the requirements for production efficiency are becoming increasingly stringent. In addition, the degree of cross-contamination between different types of lubricating oil is greatly reduced compared to existing vertically mounted filters, effectively ensuring the purity and quality of the lubricating oil. Furthermore, the horizontally mounted filter 400 effectively reduces liquid residue in the filter bag 420, reducing flushing time.

[0054] Furthermore, in this embodiment, while the air pump 510 is working, the backwash liquid is used to clean the filter 400. The two interact with each other to clean the inside of the filter 400, thereby improving the cleaning efficiency and cleaning effect of the filter 400, and facilitating the next filling of different types of lubricating oil.

[0055] It is worth noting that the backwashing liquid used is the lubricating oil used for filling. It can be the lubricating oil filled last time or the lubricating oil to be filled next time. However, when using the lubricating oil used for the next filling for cleaning, the backwashing liquid must be in other tanks besides the original oil storage tank to avoid cross contamination of the lubricating oil in the original oil storage tank.

[0056] Example 2

[0057] The horizontal automatic lubricating oil filling trolley of this embodiment is basically the same as that of embodiment 1, but further: Figure 2 In this embodiment, the air pipe 511 is connected to the filter 400 through the arc tube 520, and the height of the arc tube 520 is higher than the height of the filter 400. During the filling process of the lubricating oil, it can effectively prevent the lubricating oil from flowing into the air pipe 511 and affecting the subsequent inflation and backwashing operations; in addition, in order to further avoid the occurrence of this problem, a valve six 530 is provided on the arc tube 520, and the connection between the air pipe 511 and the arc tube 520 is blocked by the valve six 530, further preventing the lubricating oil from flowing into the air pipe 511.

[0058] In addition, combined Figure 3 In this embodiment, a valve 1 321 is provided on the delivery pipe 310, and the communication with the input branch pipe 311 is controlled by the valve 1 321; a valve 2 322 is provided on the input branch pipe 311, a valve 4 324 is provided on the output branch pipe 312, and a valve 3 323 is provided on the delivery pipe 310 between the input branch pipe 311 and the output branch pipe 312.

[0059] When filling operation is required, valve three 323 and valve six 530 are closed in advance, and valve one 321, valve two 322 and valve four 324 are opened. Under the action of the gear pump 200, the lubricating oil is sent to the input branch pipe 311 along the delivery pipe 310, and flows into the filter 400. The lubricating oil is filtered by the filter bag 420 in the filter 400. The lubricating oil after being filtered by the filter bag 420 enters between the filter bag 420 and the housing 410, and is delivered to the filling head 600 through the output branch pipe 312, and the filling head 600 fills the lubricating oil.

[0060] When different types of lubricating oil need to be filled, valve three 323 and valve four 324 are closed, and valve one 321, valve two 322 and valve six 530 are opened. The air pump 510 is started, and gas is introduced into the filter 400 through the air pump 510. Backwashing liquid is added to the filter 400, so that the lubricating oil and impurities remaining in the filter 400 are sent to the delivery pipe 310 along the input branch pipe 311 and discharged from the delivery pipe 310 to facilitate the next step of lubricating oil filling.

[0061] In this embodiment, valves are provided on the corresponding connecting pipes. The operator can accurately control the opening and closing of each valve during use to achieve the corresponding operation, thereby preventing the lubricating oil from flowing into other channels and causing production accidents. The entire operation process is simple, convenient and easy to operate.

[0062] Example 3

[0063] The horizontal automatic lubricating oil filling trolley of this embodiment is basically the same as that of embodiment 2, but further: Figure 2 In this embodiment, the delivery pipe 310 is further connected to an oil drain pipe 330 , which is located between the filling head 600 and the output branch pipe 312 , and a valve 5 331 is provided on the oil drain pipe 330 .

[0064] The filling process of the entire filling trolley remains unchanged, but certain changes occur during the process of cleaning the filter 400.

[0065] When filling different types of lubricating oil, close valve one 321 and valve four 324, and open valve two 322, valve three 323, valve five 331 and valve six 530. The air pump 510 is started, and gas is introduced into the filter 400 through the air pump 510. Backwashing liquid is added to the filter 400, so that the lubricating oil and impurities remaining in the filter 400 are sent along the input branch pipe 311 to the delivery pipe 310, and then to the oil drain pipe 330 for discharge from the oil drain pipe 330.

[0066] Compared with sending the backwashing liquid in the cleaning process to the original oil storage tank, this cleaning process can further prevent the cleaned lubricating oil from contaminating the lubricating oil in the oil storage tank.

[0067] Preferably, in this embodiment, during the flushing process, the lubricating oil to be filled is used for cleaning, thereby further ensuring the purity of the lubricating oil to be filled.

[0068] It is worth noting that in the present embodiment, when the filling trolley is used for cleaning, the amount of backwash liquid used in the horizontally placed filter 400 is reduced by 80%-85% compared to the vertically placed filter, and the flushing time is reduced by 60%-70%, thereby reducing production costs and improving work efficiency.

[0069] Example 4

[0070] The horizontal automatic lubricating oil filling trolley of this embodiment is basically the same as that of embodiment 3, but further: Figure 1 and Figure 2 In this embodiment, a control unit is provided on the bottom plate 100, which drives the filling head 600 to move up and down in the vertical direction, thereby adjusting the position of the filling head 600, that is, adjusting the distance between the filling head 600 and the filling bottle mouth, avoiding splashing of lubricating oil during the filling process, and facilitating the filling of bottles of different sizes.

[0071] The control unit of this embodiment includes a bracket 700, a screw rod 710, a cylinder 1 720 and a cylinder 2 730; wherein, the bracket 700 is vertically installed on the base plate 100, the screw rod 710 is connected to the bracket 700, and the screw rod 710 is arranged along the vertical direction, the base of the cylinder 1 720 is installed on the screw rod 710, and the front end of the telescopic rod of the cylinder 1 720 is vertically connected to the connecting plate, the base of the cylinder 2 730 is vertically fixed on the connecting plate, and the front end of the telescopic rod of the cylinder 2 730 is connected to the filling head 600.

[0072] When the height of the filling head 600 needs to be adjusted, different cylinders are controlled to operate according to actual needs. When the filling head 600 needs to be adjusted significantly, cylinder 1 720 is extended and retracted to drive the connecting plate to move up and down, that is, to drive cylinder 2 730 to move up and down as a whole. At the same time, cylinder 1 720 operates to adjust the position of the filling head 600. When the filling head 600 needs to be adjusted slightly, one of the cylinders can be operated separately to adjust the position of the filling head 600.

[0073] In addition, this embodiment is provided with an adjustment handwheel 711 on the screw rod 710. When it is necessary to fine-tune the position of the filling head 600, the operator rotates the adjustment handwheel 711 to drive the screw rod 710 to rotate, thereby driving the cylinder 1 720 to move up and down, thereby adjusting the position of the filling head 600.

[0074] In order to facilitate the adjustment of the position of the filling head 600, a slide groove 712 is provided on the bracket 700 in this embodiment, and a slider 740 is provided on the slide groove 712 to match it. It is worth noting that the slide groove 712 in this embodiment is provided along the height direction of the bracket 700. Figure 2 As shown, the delivery pipe 310 in this embodiment passes through the slider 740 and is connected to the filling head 600 .

[0075] Example 5

[0076] The horizontal automatic lubricating oil filling trolley of this embodiment is basically the same as that of embodiment 4, but further: Figure 1 and Figure 4 In this embodiment, a conveying unit is provided on one side of the bottom plate 100. The conveying unit is located on one side of the filling head 600. The bottles required for filling are conveyed by the conveying unit, thereby cooperating with the filling head 600 to improve work efficiency.

[0077] The conveying unit of this embodiment includes a conveying bracket 810 and a conveying roller 820 . A plurality of conveying rollers 820 are disposed between two conveying brackets 810 , and both ends of the conveying rollers 820 are connected to the conveying bracket 810 .

[0078] The conveying roller 820 is provided to convey the bottle body. On the one hand, it can reduce labor and the time required for manual handling. On the other hand, when conveying, the conveying roller 820 rotates, and there is rolling friction between the conveying roller 820 and the bottom surface of the bottle body, which is conducive to the movement of the bottle body and facilitates the movement of the bottle body after filling.

[0079] Example 6

[0081] In order to facilitate the connection of two adjacent conveying mechanisms, such as Figure 4 As shown, a slot 830 is provided at one end of the conveying bracket 810 of one of the conveying mechanisms, and a rotating shaft 811 is provided on the conveying bracket 810 of the adjacent conveying mechanism that is movably connected to the conveying mechanism. The rotating shaft 811 is located in the slot 830. The rotation of the conveying mechanism is achieved through the joint action of the slot 830 and the rotating shaft 811, so that the conveying mechanism can be folded together to reduce the footprint of the entire device.

[0082] In addition, in order to facilitate the operation of the operator, a control cabinet 900 is provided on the base plate 100 in this embodiment, through which operations such as filling of lubricating oil, delivery of gas and adjustment of the position of the filling head 600 are realized, thereby improving the degree of automation of the entire device.
