Description

Technical Field

[0001] This utility model relates to the field of grease filling machine technology, specifically an automatic grease filling machine for bearings. Background Technology

[0002] An automatic bearing grease applicator is a device specifically designed for automating the application of grease (commonly known as "butter") to bearings and other mechanical components. It effectively improves application efficiency, ensures the accuracy and consistency of the applied grease, reduces the labor intensity of manual operation and grease waste, and is widely used in manufacturing, automotive repair, and heavy machinery maintenance.

[0003] Existing grease filling methods generally involve manual or pneumatic filling. Manual filling is not only time-consuming and labor-intensive, but also makes it difficult to control the amount of grease added. Existing automatic filling methods require pre-squeezing the grease from the grease tank into the device and then adding the grease by squeezing, which results in some grease waste. Therefore, we propose an automatic bearing grease filling machine. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic grease dispenser for bearings, comprising a base and a top plate. A bearing mechanism for positioning a grease container is fixedly installed on the top of the base. A limiting ring inserted into the bearing mechanism is fixedly connected to the bottom of the top plate. A quantitative extraction mechanism for quantitatively extracting and conveying grease is provided on the top plate. One end of the quantitative extraction mechanism is fixedly connected to a dispensing gun. A squeezing mechanism for squeezing and conveying the grease container to the bottom of the quantitative extraction mechanism is provided on the top plate. The bearing mechanism and the top plate are connected by multiple sets of locking mechanisms.

[0006] Furthermore, the bearing mechanism includes a bearing sleeve, a positioning sleeve, and a chamfer. The bearing sleeve is fixedly installed on the top of the base.

The top of the inner wall of the positioning sleeve is provided with an inclined chamfer.

[0007] Furthermore, the extrusion mechanism includes a drive cylinder, a first threaded rod, an extrusion disc, a first threaded sleeve, and a sealing ring. The drive cylinder is fixedly installed on the top of the top plate, and the output end of the drive cylinder is fixedly connected to the first threaded rod. The top of the extrusion disc is fixedly connected to the first threaded sleeve, which is threadedly connected to the first threaded rod. A sealing ring made of rubber material is fixedly connected to the outside of the extrusion disc.

[0008] Furthermore, the quantitative extraction mechanism includes an extraction tank, an extraction pump, a delivery pipe, a clamping pipe, and a metering valve.

Detailed Implementation

[0014] 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.

[0015] Please see Figures 1-3 This utility model provides a technical solution: an automatic grease dispenser for bearings, comprising a base 1 and a top plate 3. A bearing mechanism 2 for positioning a grease container is fixedly installed on the top of the base 1. A limiting ring 4 inserted into the bearing mechanism 2 is fixedly connected to the bottom of the top plate 3. A quantitative extraction mechanism 6 for quantitatively extracting and conveying grease is provided on the top plate 3. One end of the quantitative extraction mechanism 6 is fixedly connected to a dispensing gun. A squeezing mechanism 5 for squeezing and conveying the grease container to the bottom of the quantitative extraction mechanism 6 is provided on the top plate 3. The bearing mechanism 2 and the top plate 3 are connected by multiple sets of locking mechanisms 7. The system also includes a PLC controller.

[0016] The included support mechanism 2 supports the grease container, eliminating the need to remove the grease from the container for reuse. The limiting ring 4 below the top plate 3 is then inserted into the support mechanism 2, and the top plate 3 is locked in place by the locking mechanism 7. The compression mechanism 5 then compresses the grease inside the container. The grease then works in conjunction with the quantitative extraction mechanism 6 to deliver a measured amount of grease, which can be dispensed into the bearing position via a dispensing gun. This compression extraction method prevents slow grease output and ensures uniform grease delivery. The included PLC controller controls the operation of the compression mechanism 5 and the quantitative extraction mechanism 6, enabling the quantitative extraction of grease.

[0017] Please see Figure 1 and Figure 2The bearing mechanism 2 includes a bearing sleeve 8, a positioning sleeve 9, and a chamfer 10. The bearing sleeve 8 is fixedly installed on the top of the base 1. The positioning sleeve 9, which fits against the inner wall of the bearing sleeve 8, is placed inside the bearing sleeve 8. The top of the inner wall of the positioning sleeve 9 is provided with an inclined chamfer 10.

[0018] The positioning sleeve 9 is inserted into the inside of the bearing sleeve 8, which can position different Google butter buckets and make it easier for the squeezing mechanism 5 to extend into the inside of the butter bucket. The inclined chamfer 10 can make it easy for the butter bucket to be put into the inside of the positioning sleeve 9, and also makes it easy to place the butter bucket lifting ring.

[0019] Please see Figure 1 and Figure 2 The locking mechanism 7 includes a hinge seat 22, a connecting frame 23, a second threaded sleeve 24, and a second threaded rod 25. The side wall of the bearing sleeve 8 is rotatably connected to the connecting frame 23 through the hinge seat 22. One end of the connecting frame 23 is fixedly connected to the second threaded sleeve 24. The second threaded sleeve 24 is internally threaded with the second threaded rod 25. The bottom of the second threaded rod 25 is fixedly connected to a pressure plate 26. The pressure plate 26 is made of rubber.

[0020] After the top plate 3 is placed, the connecting frame 23 is rotated along the hinge seat 22 to the top plate 3. Then, the second threaded rod 25 is rotated to rotate and move down along the inside of the second threaded sleeve 24. Then, the pressure plate 26 can be pressed and positioned against the top of the top plate 3.

[0021] Please see Figure 1 and Figure 3 The extrusion mechanism 5 includes a drive cylinder 11, a first threaded rod 12, an extrusion disc 13, a first threaded sleeve 14, and a sealing ring 15. The drive cylinder 11 is fixedly installed on the top of the top plate 3. The output end of the drive cylinder 11 is fixedly connected to the first threaded rod 12. The top of the extrusion disc 13 is fixedly connected to the first threaded sleeve 14, which is threadedly connected to the first threaded rod 12. The sealing ring 15, made of rubber material, is fixedly connected to the outside of the extrusion disc 13.

[0022] After the butter drum and top plate 3 are installed, the drive cylinder 11 drives the extrusion plate 13 to descend, so that the extrusion plate 13 can be used to extrude the butter. The sealing ring 15 is set so that it can fit completely with the butter drum, ensuring that the butter can be fully extruded and output. Thus, the butter can be extracted and transported by the quantitative extraction mechanism 6. The extrusion plate 13 and the drive cylinder 11 are connected by the first threaded rod 12 and the first threaded sleeve 14, so that extrusion plates 13 of different specifications can be replaced and maintained.

[0023] Please see Figure 1 and Figure 3 The quantitative extraction mechanism 6 includes an extraction tank 16, an extraction pump 17, a delivery pipe 18, a clamping pipe 19, and a metering valve 20. The extraction tank 16 is provided through the extrusion plate 13. The extraction pump 17 is fixedly installed on the top of the top plate 3. The feed end of the extraction pump 17 is fixedly connected to the delivery pipe 18. One end of the delivery pipe 18 is connected to the extraction tank 16 through the clamping pipe 19. The extraction tank 16 is set as a frustum-shaped structure with a bottom dimension larger than the top dimension. The discharge end of the extraction pump 17 is fixedly connected to the metering valve 20. One end of the metering valve 20 is fixedly connected to the dispensing gun through the connecting pipe 21.

[0024] During the extrusion of the butter by the extrusion plate 13, the butter is conveyed to the delivery pipe 18 through the extraction groove 16 with a larger bottom size. The bottom of the delivery pipe 18 is connected to the extraction groove 16 through the clamping pipe 19, which makes it easy to disassemble the delivery pipe 18 at the same time as the extrusion plate 13. After the butter is extruded, the extraction pump 17 works to deliver the butter. The metering valve 20 set during the butter delivery can accurately measure the output amount of butter to prevent the butter from being over-extruded or under-extruded. The extracted butter can then be discharged through the connecting pipe 21 and the filling gun.

[0025] Please see Figures 1-3 The PLC controller is electrically connected to the drive cylinder 11, the extraction pump 17 and the metering valve 20. The PLC controller can be programmed to control the operation of the components to ensure that the grease can be delivered in a quantitative manner.

[0026] In use, firstly, the supporting mechanism 2 supports the grease container, eliminating the need to remove the grease from the container before use. Then, the limiting ring 4 below the top plate 3 is inserted into the supporting mechanism 2, and the top plate 3 is locked in place by the locking mechanism 7. Next, the squeezing mechanism 5 squeezes the grease inside the container. The grease then works in conjunction with the quantitative extraction mechanism 6 to deliver a measured amount of grease, which can be added to the bearing position via a filling gun. This squeezing extraction design prevents slow grease delivery and ensures even grease distribution. The PLC controller can control the operation of the extrusion mechanism 5 and the quantitative extraction mechanism 6, thereby realizing the quantitative extraction of butter. The positioning sleeve 9 is inserted into the inside of the bearing sleeve 8, which can position butter buckets of different sizes and make it easier for the extrusion mechanism 5 to extend into the inside of the butter bucket. The inclined chamfer 10 can facilitate the placement of the butter bucket into the positioning sleeve 9 and also facilitates the placement of the butter bucket lifting ring. After the top plate 3 is placed, the connecting frame 23 is rotated along the hinge seat 22 to the top plate 3, and then the second threaded rod 25 is rotated along the second threaded sleeve. The cylinder 24 rotates downwards, allowing the pressure plate 26 to contact and press against the top plate 3 for positioning. After the grease bucket and top plate 3 are installed, the drive cylinder 11 lowers the extrusion disc 13, allowing the grease to be extruded. The sealing ring 15 ensures complete contact with the grease bucket, guaranteeing sufficient extrusion and output of the grease. This allows the grease to be extracted and conveyed by the quantitative extraction mechanism 6. The extrusion disc 13 and the drive cylinder 11 are connected by a first threaded rod 12 and a first threaded sleeve 14, enabling the extrusion discs 13 of different specifications to be adjusted. During maintenance, when the extrusion disc 13 extrudes the grease, the grease is conveyed to the delivery pipe 18 through the extraction groove 16 with a larger bottom size. The bottom of the delivery pipe 18 is connected to the extraction groove 16 through the clamping pipe 19, which makes it easy to disassemble the delivery pipe 18 at the same time as the extrusion disc 13. After the grease is extruded, the extraction pump 17 works to deliver the grease. The metering valve 20 set during the grease delivery can accurately measure the amount of grease output to prevent excessive or insufficient grease extrusion. The extracted grease can then be discharged through the connecting pipe 21 and the filling gun.
