Description

Technical Field

[0001] The invention relates to the technical field of electric rollers, in particular to an electric roller with an oil filter assembly. Background Art

[0002] The electric drum is a new type of drive device that places the motor and reducer together inside the drum. It is mainly used in fixed and mobile belt conveyors, replacing the traditional separate drive device where the motor and reducer are placed outside the drive drum.

[0003] Chinese patent application number: CN201922390239.5 discloses an improved oil-cooled electric drum structure. The device realizes power transmission through a driving gear, three driven gears and an internal gear. The drum is driven to rotate by the rotation of the drive motor. During the rotation, the three driven gears and the internal gear on the drum are in contact with the cooling oil to achieve the effect of heat dissipation. The scraper is "L" shaped and tilted, so that the cooling oil inside the scraper will not flow down before it reaches the top, thereby pouring the cooling oil onto the drive motor near the highest point to achieve better heat dissipation effect. This device can meet general use requirements, but it still has the following disadvantages in actual use:

[0004] 1. In the oil-cooled electric roller in the prior art, the cooling oil is affected by friction and pressure, generating heat. This heat causes the cooling oil temperature to rise, which may cause oxidation and degradation of the cooling oil, resulting in the generation of impurities that affect the operation of the electric roller.

[0005] 2. The oil-cooled electric drum in the prior art will reduce the amount of cooling oil due to mechanical wear and aging after a certain period of use, and a large amount of waste residue will remain in the cooling oil, resulting in a decrease in the cooling effect of the cooling oil and increased wear. Therefore, it needs to be replaced regularly. However, due to the certain viscosity of the cooling oil, the cooling oil in the drum is not cleaned thoroughly enough, and a certain amount of waste oil and impurities will be stuck in the drum, making the replacement of the cooling oil incomplete.

[0023] 1. In the present invention, when changing the cooling oil, first separate the oil inlet seat from the first end cover seat, then take out the oil filter plate, the filter pressure plate, and the limit seat plate from the installation groove, so that the cooling oil in the intermediate support cylinder is discharged into the designated container through the delivery pipe, and the air inlet valve is connected to the air pump through the air pipe, and the high-pressure gas is discharged through the first jet hole.

[0024] 2. The present invention provides a sliding groove and an oil filter assembly. First, as the intermediate support tube rotates, the flexible block stirs the cooling oil, thereby improving the fluidity of the cooling oil and increasing the contact area of ​​the cooling oil, thereby improving the overall heat dissipation performance of the intermediate support tube. Second, when the flexible block passes through the bottom of the magnetic block, the movable plate at the top of the sliding groove drives the elastic receiving part to move toward the magnetic block, thereby generating a negative pressure inside the elastic receiving part, sucking part of the cooling oil into the elastic receiving part, thereby reducing the distance between the cooling oil and the outer rubber sleeve in disguise, and further improving the heat dissipation effect of the intermediate support tube. Third, after the movable plate is separated from the adsorption of the magnetic block, under the influence of centrifugal force, the movable plate squeezes the elastic receiving part, so that the cooling oil inside the elastic receiving part is filtered by the filter and then sprayed out from the oil injection pipe. The filter retains impurities in the cooling oil inside the elastic receiving part, thereby completing the collection of impurities. At the same time, since the spray ports of the oil injection pipe are all facing the motor, the cooling oil sprayed from the oil injection pipe impacts and cleans the motor housing.

[0053] Example 2

[0054] Although the above embodiment can improve the cooling effect of the cooling oil inside the intermediate support tube 1 to a certain extent, in actual use, as the intermediate support tube 1 continues to rotate, the cooling oil inside the intermediate support tube 1 will inevitably degrade due to high temperature. If the impurities generated by the high-temperature degradation of the cooling oil cannot be collected, the cooling effect of the cooling oil will inevitably be affected as the intermediate support tube 1 continues to operate. In view of this, the technical solution based on the first embodiment has been modified, and the modified technical solution is as follows.

The elastic receiving member 402 is a bellows.

[0061] When in use, the electric drum needs to be assembled first. First, the oil filter assembly 4 is sent into the sliding groove 3. The bottom of the sliding groove 3 is symmetrically provided with blocks for limiting the bottom movable plate 401. In the process of sending the oil filter assembly 4 into the sliding groove 3, the bottom movable plate 401 is first inserted into the groove formed by the block and the bottom of the sliding groove 3, and then the top movable plate 401 is squeezed to make the elastic receiving part 402 and the elastic part 404 shrink, so that the oil filter assembly 4 can smoothly enter the interior of the sliding groove 3, and the flexible block 405 on the top movable plate 401 extends out of the sliding groove 3 and is located inside the middle support cylinder 1 (specifically as shown in FIG.

The cooling oil entering the oil inlet seat 607 is filtered by the filter pressure plate 610 and the oil filter plate 609, and then enters the middle support cylinder 1 through the delivery pipe 613, thereby completing the preparation work of the electric roller.

[0066] After completing the preparation work of the electric roller, the electric roller is installed in the corresponding device so that the first end shaft 603 and the second end shaft 703 are fixedly connected to the corresponding device respectively. At this time, the oil inlet valve 608 is located at the bottom of the intermediate support cylinder 1 (that is, the magnetic block 13 on the motor 501 is located at the bottom of the intermediate support cylinder 1). Then the control system starts the motor 501, and the output end of the motor 501 drives the main drive gear 502 to rotate. The main drive gear 502 drives the ring gear 10 to rotate through the first auxiliary gear 903 and the second auxiliary gear 904. Since the ring gear 10 is fixedly connected to the first end cover seat 601, the first end cover seat 601 and the intermediate support cylinder 1 is fixedly connected, so that when the main driving gear 502 rotates, the intermediate support cylinder 1 is synchronously driven to rotate. At the same time, since the first end cover seat 601 is rotatably connected to the first end shaft 603 through the first bearing 602 and the first oil seal ring 604, and the second end cover seat 701 is rotatably connected to the second end shaft 703 through the second bearing 702 and the second oil seal ring 704, the first end shaft 603 and the second end shaft 703 are respectively fixedly connected to the corresponding devices. Therefore, when the motor 501 drives the intermediate support cylinder 1 to rotate, the first end shaft 603 and the second end shaft 703 will not rotate, thereby keeping the position of the magnetic block 13 on the motor 501 unchanged.

[0067] As the intermediate support tube 1 rotates, the flexible block 405 stirs the cooling oil inside the intermediate support tube 1, so that the flexible block 405 drives the cooling oil to flip along with the intermediate support tube 1, thereby improving the fluidity of the cooling oil and increasing the contact area of ​​the cooling oil, thereby improving the overall heat dissipation performance of the intermediate support tube 1.

[0068] During the rotation of the intermediate support cylinder 1, due to the influence of centrifugal force, the movable plate 401 located at the top of the sliding groove 3 squeezes the elastic receiving part 402 and the elastic part 404, so that the movable plate 401 at the top of the sliding groove 3 moves to the bottom of the sliding groove 3, thereby causing the gas inside the elastic receiving part 402 to be ejected from the oil injection pipe 407. When the intermediate support cylinder 1 drives the flexible block 405 to pass through the bottom of the magnetic block 13 on the motor 501, since the movable plate 401 is made of ferromagnetic material, the magnetic block 13 generates magnetic attraction on the movable plate 401, thereby The movable plate 401 moves toward the magnetic block 13. At the same time, since the bottom of the sliding groove 3 is symmetrically provided with a stopper, the stopper is located at the bottom movable plate 401 of the sliding groove 3 to limit the position. Therefore, in the process of the magnetic block 13 generating magnetic attraction on the movable plate 401, only the movable plate 401 located at the top of the sliding groove 3 can move toward the magnetic block 13. When the movable plate 401 moves toward the magnetic block 13, the movable plate 401 drives the elastic receiving part 402 and the elastic part 404 to stretch, so that the elastic receiving part 402 and the elastic part 404 return to their unloaded state. In the compressed state, the elastic receiving part 402 generates negative pressure inside the elastic receiving part 402 during the stretching process, thereby sucking part of the cooling oil inside the intermediate support tube 1 into the elastic receiving part 402, thereby reducing the distance between the cooling oil and the outer rubber sleeve 2 in disguised form, and further improving the heat dissipation effect of the intermediate support tube 1; as the intermediate support tube 1 continues to rotate, the movable plate 401 is separated from the adsorption of the magnetic block 13, and the movable plate 401 squeezes the elastic receiving part 402 and the elastic part 404 again due to the influence of centrifugal force, so that the elastic receiving part 402 inside The stored cooling oil is filtered by the filter and then sprayed out from the oil spray pipe 407. The filter retains the impurities in the cooling oil that are degraded by heat inside the elastic storage part 402, thereby completing the collection of impurities and avoiding excessive impurities in the cooling oil, which would cause the heat dissipation effect of the intermediate support tube 1 to be reduced. Since the spray ports of the oil spray pipe 407 are all facing the motor 501, the cooling oil sprayed from the oil spray pipe 407 impacts and cleans the housing of the motor 501, thereby avoiding the accumulation of excessive impurities in the housing of the motor 501, thereby affecting the cooling effect of the cooling oil.

[0069] As the intermediate support cylinder 1 continues to operate, the movable plate 401 at the top of the sliding groove 3 continuously squeezes the elastic receiving member 402 inside the sliding groove 3 under the influence of the centrifugal force of the intermediate support cylinder 1 and the magnetic attraction of the magnetic block 13, so that the elastic receiving member 402 continuously absorbs the impurities of the cooling oil, causing the impurities to continuously accumulate inside the elastic receiving member 402. Since a pressure sensor is provided at the connection between the elastic member 404 and the movable plate 401, the control system constantly monitors the compression amount of the elastic member 404 under the influence of the centrifugal force during the rotation of the intermediate support cylinder 1; assuming that the elastic member 404 is in the initial state (i.e., the elastic member 402 is in the elastic receiving member 402), the elastic member 404 is compressed by the centrifugal force. When there are no impurities on the inside), the compression amount affected by the centrifugal force is A. As the middle support cylinder 1 continues to operate, more and more impurities are accumulated inside the elastic receiving part 402. As a result, when the movable plate 401 at the top of the sliding groove 3 squeezes the elastic part 404 and the elastic receiving part 402 due to the influence of centrifugal force, the impurities inside the elastic receiving part 402 will hinder the movement of the movable plate 401, so that the movable plate 401 cannot effectively compress the elastic part 404. At this time, the compression amount of the elastic part 404 is A+N, where N is the resistance caused by the impurities inside the elastic receiving part 402 to the movement of the movable plate 401. When the control system detects that the elastic part 404 is When the compression amount of the elastic member 404 exceeds the set value, it indicates that there are too many impurities accumulated inside the elastic receiving member 402, and the oil filter assembly 4 needs to be replaced. If the intermediate support cylinder 1 is still in working condition at this time, the solenoid valve inside the second jet hole 711 and the air intake valve 707 are controlled to open by the control system, and the air pump is controlled to supply air to the air intake valve 707. Since the air intake valve 707 is connected to the air pump through the delivery air pipe, and the second jet hole 711 is connected to the air intake duct 8, the air intake duct 8 is connected to the air nozzle on the elastic receiving member 402, after the air pump is started, the high-pressure gas is passed through the air intake valve 707, the air intake connecting pipe 706, the air intake hole 711, and the air intake valve 707. 08 is transported to the annular air delivery groove 709, and finally discharged to the interior of the middle elastic receiving part 402 from the second jet hole 711 connected to the side of the annular air delivery groove 709. The airflow impacts the impurities inside the elastic receiving part 402 and the filter screen on the oil injection pipe 407. After being impacted by the airflow, the impurities inside the elastic receiving part 402 move to the end close to the blockage and accumulate on the end of the elastic receiving part 402 close to the blockage. After the filter screen is impacted, the impurities adhered to the filter screen are cleaned off, and then the solenoid valve in the second jet hole 711 and the air inlet valve 707 are controlled to close, and the air pump stops supplying air to the annular air delivery groove 709.

[0070] Since the two movable plates 401 are connected to each other through the elastic member 404, even if impurities in the elastic receiving member 402 are accumulated at the end of the elastic receiving member 402, as the intermediate support cylinder 1 continues to rotate, under the influence of centrifugal force, the movable plate 401 at the top of the sliding groove 3 deflects with the contact point between the end of the movable plate 401 and the block as the center (such as Figure 9 As shown, the end of the movable plate 401 adopts a chamfered design) to continue to squeeze the elastic storage part 402 and discharge the gas discharged into the elastic storage part 402, so that the elastic storage part 402 can continue to absorb impurities, so that the internal space of the elastic storage part 402 can be fully utilized.

[0071] After the work is completed, the cooling oil inside the middle support tube 1 is first discharged, and then the oil filter assembly 4 and the block are removed from the middle support tube 1. Then, the air pump is continued to be controlled to supply air to the annular air supply groove 709, and the solenoid valve in the second jet hole 711 is controlled to open, so that the air pump injects high-pressure gas into the elastic receiving part 402. Since the block has been removed from the middle support tube 1, the oil filter assembly 4 loses the limit of the block, so that the oil filter assembly 4 is gradually flushed out from the sliding groove 3, avoiding excessive accumulation of impurities inside the elastic receiving part 402 that are difficult to be removed.

[0072] After the oil filter assembly 4 is taken out, a new oil filter assembly 4 is replaced, and the electric drum is assembled again so that it can continue to work.
