Description

Technical Field

[0001] The utility model relates to the technical field of lubrication and maintenance equipment for mechanical equipment, in particular to a lubricating oil uniform filling device for the upper cover of a paper feeder. Background Art

[0002] At present, in industries such as printing, copying, and packaging, the paper feeder is a key component of mechanical equipment, responsible for smoothly and accurately conveying paper. To ensure the continuous and efficient operation of the equipment, the upper cover part of the paper feeder (especially between the transmission gear sets) requires good lubrication to reduce friction, prevent wear, extend service life, and ensure the smoothness and accuracy of paper conveyance. An effective lubricating oil uniform filling device can automatically or semi-automatically provide an appropriate amount and uniform lubrication for these components, thus supporting the equipment to maintain the best working state for a long time.

[0003] In the traditional method, users may need to manually add lubricating oil to the paper feeder regularly. Although this method is simple, it has certain defects. Specifically, it is difficult to ensure the uniformity and accuracy of lubricating oil filling. Excessive or insufficient lubrication will not only affect mechanical efficiency but also may lead to the accumulation of oil stains and increased wear of components, and even affect the smoothness of paper transmission. Secondly, the internal structure of the equipment is complex, especially the manual lubrication operation in deep and hidden areas is extremely inconvenient, which is easy to form lubrication blind spots and increase the risk of failure. Finally, the improper handling of lubricating oil may endanger the health of operators, not only wasting lubricating oil but also causing environmental pollution. Summary of the Utility Model

[0004] In order to overcome the disadvantages of inconvenient operation and difficult uniform lubrication when manually filling lubricating oil in the prior art, a lubricating oil uniform filling device for the upper cover of a paper feeder is provided.

[0005] The technical implementation solution of the present utility model is as follows: A lubricating oil uniform filling device for the upper cover of a paper feeder, including an oil filling machine and a placement rack. The oil filling machine is the main carrier for filling lubricating oil in this device. The placement rack is installed on the plane at the lower part of the oil filling machine. The placement rack is used to limit and place the upper cover of the paper feeder to be filled. The upper cover of the paper feeder is integrated with a gear set to be lubricated. It further includes: a driving motor installed on the side of the oil filling machine close to the placement rack; a support plate fixedly connected to the plane of the oil filling machine where the placement rack is located, and the output shaft of the driving motor penetrates through the support plate; a spline shaft installed on the output shaft of the driving motor, and a spline groove adapted to the spline shaft is opened on the rotating shaft of the docking gear on the gear set of the upper cover of the paper feeder; an oil injection pipe arranged on the side of the oil filling machine close to the support plate; an electric push rod installed in the machine body at the lower part of the oil filling machine. A chute is opened on the plane of the oil filling machine where the placement rack is located, and the placement rack is slidably installed on the lower plane of the oil filling machine through this chute. The push rod of the electric push rod is connected to the placement rack. The upper cover of the paper feeder on the placement rack is driven to move through the electric push rod, so that the spline groove on the gear set of the upper cover of the paper feeder is docked to the spline shaft. Then, the driving motor drives the gear set to rotate at a uniform speed through the spline shaft, and the oil filling machine uniformly fills lubricating oil into the rotating gear set through the oil injection pipe.

[0006] As a preferred technical solution of the present utility model, both the spline shaft and the placement rack are replaceably installed, and can be replaced according to the actual size of the upper cover of the paper feeder and the gear set thereon, improving the applicability of the filling device.

[0007] As a preferred technical solution of the present utility model, a collection box is installed on one side of the placement rack close to the gear set. The collection box is used to collect the lubricating oil that slides off when lubricating the gear set. The collection box can recycle the recovered lubricating oil, reducing the waste of lubricating oil.

[0008] As a preferred technical solution of the present utility model, a sponge is placed in the collection box. The sponge fills the inside of the collection box. The sponge is used to adsorb the lubricating oil collected in the collection box, reducing the subsequent operation of cleaning the collection box. The lubricating oil in the sponge can be easily recycled after being squeezed out later.

[0009] As a preferred technical solution of the present utility model, a housing is provided at the place on the oil filling machine for placing the upper cover of the paper feeder. A door panel is hinged on the side wall of the housing. A handle is provided on the outer wall of the door panel. The door panel covers the housing, enabling the lubricating oil to be filled in a relatively sealed environment for the upper cover of the paper feeder and the gear set, reducing the influence of external dust on the lubricating oil filling.

[0010] As a preferred technical solution of the present utility model, a magnetic attraction block is provided on the lower housing of the oil injector near the door panel, a magnet is provided on the inner wall of the door panel, and the magnetic attraction block cooperates with the magnet to adsorb the door panel, improving the convenience of use of the door panel.

[0011] As a preferred technical solution of the present utility model, one side of the oil injector is communicated with a dust blowing gun through a pipeline, and the dust blowing gun is disposed at a position near the gear set after passing through the outer shell.

[0012] As a preferred technical solution of the present utility model, a flow guide cover is detachably installed on the air outlet of the dust blowing gun, the air outlet of the flow guide cover is a straight slit, and the flow guide cover is used to quickly introduce the air flow blown out by the dust blowing gun onto the gear set to remove the dust on the gear set.

[0013] The beneficial effects of the present utility model are as follows: 1. The present utility model adapts the spline shaft to the spline groove on the gear set, and drives the gear set to rotate at a uniform speed by a driving motor, and evenly injects lubricating oil in cooperation with the oil injection pipe to ensure that each gear component is properly lubricated. The replaceable spline shaft and the placement rack design enable the device to adapt to the upper covers of paper feeders and their gear sets of different sizes, improving the versatility and flexibility of the device.

[0014] 2. The present utility model can recycle the slipped lubricating oil through the design of the collection box and the internal sponge, reducing the waste of lubricating oil, and facilitating subsequent treatment and reuse. Moreover, the outer shell and the door panel are provided to provide a relatively sealed environment for the injection process, effectively preventing external dust from contaminating the lubricating oil and ensuring the lubrication quality.

[0015] 3. The present utility model can also improve the convenience of using the door panel through the combination of the magnetic attraction block and the magnet, simplifying the operation process. By using the dust blowing gun and the flow guide cover again, the gear set can be efficiently cleaned before injecting lubricating oil, removing dust and impurities, and further improving the lubrication effect and the service life of the equipment.

Detailed implementation mode

[0025] The present utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments, but it is not intended to limit the present utility model.

[0026] Embodiment: A lubricating oil uniform injection device for the upper cover of a paper feeder, as Figures 2 - 6 shown, includes an oil injector 1 and a placement rack 2. The oil injector 1 is the main carrier for injecting lubricating oil into the device. The placement rack 2 is installed on the plane at the lower part of the oil injector 1. The placement rack 2 is used to limit and place the upper cover 3 of the paper feeder to be injected. The upper cover 3 of the paper feeder integrates a gear set 4 to be lubricated. It further includes: a drive motor 6, installed on the side of the oil injector 1 close to the placement rack 2; a support plate 8, fixedly connected to the plane of the oil injector 1 where the placement rack 2 is located. The output shaft of the drive motor 6 penetrates through the support plate 8; a spline shaft 7, installed on the output shaft of the drive motor 6. A spline groove 5 adapted to the spline shaft 7 is opened on the rotating shaft of the mating gear on the gear set 4 of the upper cover 3 of the paper feeder; an oil injection pipe 9, arranged on the side of the oil injector 1 close to the support plate 8; an electric push rod 10, installed inside the lower part of the oil injector 1. A sliding groove 11 is opened on the plane of the oil injector 1 where the placement rack 2 is located. The placement rack 2 is slidably installed on the lower plane of the oil injector 1 through this sliding groove 11. The push rod of the electric push rod 10 is connected to the placement rack 2. The upper cover 3 of the paper feeder on the placement rack 2 is driven to move through the electric push rod 10, so that the spline groove 5 on the gear set 4 of the upper cover 3 of the paper feeder is docked with the spline shaft 7. Then, the drive motor 6 drives the gear set 4 to rotate at a uniform speed through the spline shaft 7, and the oil injector 1 injects lubricating oil uniformly into the rotating gear set 4 through the oil injection pipe 9; both the spline shaft 7 and the placement rack 2 are replaceably installed, and can be replaced according to the actual size of the upper cover 3 of the paper feeder and the gear set 4 thereon, improving the applicability of the injection device.

[0027] As Figure 3 shown, a collection box 12 is installed on one side of the placement rack 2 close to the gear set 4. The collection box 12 is used to collect the lubricating oil that slips off when lubricating the gear set 4. The collection box 12 can recycle the recovered lubricating oil, reducing the waste of lubricating oil; a sponge 13 is placed in the collection box 12. The sponge 13 fills the inside of the collection box 12. The sponge 13 is used to adsorb the lubricating oil collected in the collection box 12, reducing the subsequent operation of cleaning the collection box 12. After squeezing out the lubricating oil in the sponge 13 later, it can be conveniently recycled.

[0028] As Figure 1 , Figure 2 and Figure 7 shown, an outer shell 14 is provided at the place of the paper feeder upper cover 3 placed on the oil injector 1. A door panel 15 is hinged on the side wall of the outer shell 14. A handle is provided on the outer wall of the door panel 15. The door panel 15 covers the outer shell 14, so that the lubricating oil is filled in a relatively sealed environment for the paper feeder upper cover 3 and the gear set 4, reducing the influence of external dust on the lubricating oil filling; a magnetic attraction block 16 is provided on the lower shell of the oil injector 1 close to the door panel 15. A magnet is provided on the inner wall of the door panel 15. The magnetic attraction block 16 cooperates with the magnet and adsorbs the door panel 15, improving the usability of the door panel 15.

[0029] As Figure 7 and Figure 8 shown, one side of the oil injector 1 is connected with a dust blowing gun 17 through a pipeline. The dust blowing gun 17 is arranged at a position close to the gear set 4 after passing through the outer shell 14; a flow guide cover 18 is detachably installed on the air outlet of the dust blowing gun 17. The air outlet of the flow guide cover 18 is a straight slit. The flow guide cover 18 is used to quickly introduce the air flow blown out by the dust blowing gun 17 onto the gear set 4 to remove the dust on the gear set 4.

[0030] When using this device to add lubricating oil to the gear set 4 of the upper cover 3 of the paper feeder, turn the door panel 15 on the outer shell 14 open by the handle, and stably place the upper cover 3 of the paper feeder to be lubricated on the placement rack 2. Close the door panel 15 and then activate the electric push rod 10. The electric push rod 10 drives the placement rack 2 through the push rod, so that the placement rack 2 drives the upper cover 3 of the paper feeder placed thereon to move towards the support plate 8 until the gear set 4 of the upper cover 3 of the paper feeder moves to a predetermined position close to the spline shaft 7. The gear with the spline groove 5 on the gear set 4 is inserted onto the spline shaft 7. Then start the drive motor 6. The output shaft of the drive motor 6 will drive the spline shaft 7 to rotate. The rotating spline shaft 7 drives the gear set 4 to rotate at a uniform speed. At this time, after installing the diversion cover 18 on the air outlet of the dust blowing gun 17, activate the dust blowing gun 17 to blow high-speed air through the diversion cover 18 onto the rotating gear set 4, so as to remove possible residual dust and other impurities on the gear set 4 for subsequent lubrication work. After fully cleaning the gear set 4, turn off the dust blowing gun 17. Then activate the oil injector 1. The oil injector 1 evenly adds lubricating oil to the gear set 4 rotating at a low speed through the oil injection pipe 9. During the injection process, the excess or dripping lubricating oil will be absorbed by the sponge 13 in the collection box 12, reducing the waste of lubricating oil and facilitating subsequent recycling. When the gear set 4 is fully lubricated, turn off the oil injector 1 and stop the drive motor 6. Then drive the placement rack 2 back to its original position through the electric push rod 10, and open the door panel 15 on the outer shell 14. Finally, take out the lubricated upper cover 3 of the paper feeder from the placement rack 2.

[0031] The above embodiments are only the preferred embodiments of the present invention and are not used to limit the scope of implementation of the present invention. Therefore, all equivalent changes made to the content described in the claims of the present invention should be included within the scope of the claims of the present invention.
