Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 A new type of roller for a drum door in this embodiment includes a roller body 1, a roller guide rail 2 and a roller seat 3. A rotating component is installed on the roller body 1, and a lubrication component is installed on the roller body 1.

[0024] It should be noted that the roller seat 3 is fixedly connected to the door plate of the drum door, and the roller body 1 rolls to drive the drum door to open and close.

[0025] Embodiment 1: The rotating assembly includes a double bearing 4 fixedly installed inside the roller body 1 , a wheel axle 5 is rotatably installed inside the double bearing 4 , and a screw 6 is fixedly installed at one end of the wheel axle 5 .

[0026] A second extension hole is opened on the right side of the roller seat 3, and the screw rod 6 extends to the outside of the roller seat 3 through the second extension hole. The outer side of the screw rod 6 is threadedly connected with a locking nut 7. The user installs the wheel axle 5 on the roller seat 3 through the locking nut 7.

[0027] Among them, a mounting tube 8 is fixedly installed on the right side of the double bearing 4, and a first extension hole is opened on the left side of the roller seat 3. The mounting tube 8 extends to the interior of the roller seat 3 through the first extension hole, which is convenient for the wheel axle 5 and the screw 6 to be limitedly installed with the roller seat 3.

[0028] A protective oil seal 9 is fixedly installed inside the roller body 1. A mounting groove is opened inside the roller body 1. The double bearing 4 and the protective oil seal 9 are fixedly connected to the roller body 1 through the mounting groove. A return spring 10 is fixedly installed inside the mounting cylinder 8 and the roller seat 3.

[0029] It should be noted that the roller of the new drum door is equipped with a rotating component, which changes the sliding friction between the roller and the shaft into rolling friction, thereby greatly reducing the thrust. Only 20% to 30% of the original thrust is required, which is convenient for operators to push and use, reduces the workload of operators, reduces the situation where the drum door should slide and cause failures due to improper operation, and improves the overall quality and effect of the device.

[0030] Specifically, when the roller of the new rotary drum door is in use, the wheel axle 5 and the screw 6 are passed through the first extension hole and the second extension hole to penetrate the outer side of the roller seat 3, and at the same time, the mounting tube 8 is extended to the inside of the roller seat 3, and then the locking nut 7 is threadedly installed on the screw 6, so as to fix the wheel axle 5 and the screw 6 inside the roller seat 3. When the drum door needs to be moved, the roller body 1 rolls on the roller guide rail 2. At the same time, through the rotation cooperation of the double bearings 4 and the wheel axle 5, the sliding friction between the roller and the shaft is changed to rolling friction, so that the thrust is greatly reduced, which is convenient for the operator to push and use, reduces the operator's workload, and improves the overall use quality and effect of the device.

[0031] Example 2: Please refer to Figure 1 On the basis of the first embodiment, a lubrication assembly is further installed on the roller body 1, and the lubrication assembly includes a sealing cover 11 movably installed on the left side of the roller body 1, a bolt 12 is threadedly connected to the left side of the roller body 1, a connecting frame 13 is fixedly installed on the left side of the sealing cover 11, and an oil tank 14 is fixedly installed on the inner wall of the connecting frame 13.

[0032] A liquid pump 15 is fixedly installed at the bottom of the inner wall of the connecting frame 13 , and a connecting pipe is fixedly installed at the input end of the liquid pump 15 to facilitate the extraction of lubricating oil in the oil tank 14 .

[0033] It should be noted that a microcontroller is installed at the bottom of the inner wall of the connection frame 13, and the microcontroller is connected to the liquid pump 15 by signal, and the microcontroller is connected to the external control device by signal, so that the user can control the start time of the liquid pump 15.

[0034] A liquid guide tube 16 is fixedly installed at the output end of the liquid pump 15. Through holes are opened on the right side of the connecting frame 13 and the inside of the sealing cover 11. The liquid guide tube 16 extends to the inside of the roller body 1 through the through holes, so as to facilitate lubrication of the double bearings 4 and the wheel axle 5 inside the roller body 1.

[0035] Among them, a nozzle 17 is fixedly installed on one side of the liquid guide tube 16, an oil inlet pipe 18 is fixedly installed on the top of the oil tank 14, and a box cover is threadedly connected to the top of the oil inlet pipe 18 to facilitate sealing of the oil tank 14. A through hole is opened at the top of the connecting frame 13, and the oil inlet pipe 18 extends to the outside of the connecting frame 13 through the through hole, which is convenient for the user to pour lubricating oil into the oil tank 14.

[0036] It should be noted that the roller of the new drum door is equipped with a lubrication component to facilitate lubrication and maintenance of the internal double bearings 4 and the axle 5, reduce the wear of the double bearings 4 and the axle 5, improve the quality of use of the double bearings 4 and the axle 5, and thus increase the overall service life of the device.

[0037] Specifically, the roller of the new drum door pours the lubricating liquid into the oil tank 14 through the oil inlet pipe 18. When the double bearing 4 and the wheel axle 5 need to be lubricated, the liquid pump 15 is started by the microcontroller, and the lubricating liquid in the oil tank 14 is extracted to the inside of the liquid guide pipe 16 through the connecting pipe, and sprayed through the nozzle 17, so as to reduce the wear of the double bearing 4 and the wheel axle 5, improve the use quality of the double bearing 4 and the wheel axle 5, and thus increase the service life of the entire device. The sealing cover 11 and the protective oil seal 9 can seal the roller body 1, and reduce the lubricating oil from overflowing from the roller body 1 through the openings or grooves.

[0038] The working principle of the above embodiment is:

[0039] (1) When the roller of the new rotary drum door is used, the wheel axle 5 and the screw 6 are passed through the first extension hole and the second extension hole to penetrate the outer side of the roller seat 3, and the mounting tube 8 is extended to the inside of the roller seat 3. Then, the locking nut 7 is threadedly installed on the screw 6, and the wheel axle 5 and the screw 6 are fixed and limited inside the roller seat 3. When the drum door needs to be moved, the roller body 1 rolls on the roller guide rail 2. At the same time, through the rotation cooperation of the double bearing 4 and the wheel axle 5, the sliding friction between the roller and the shaft is changed to rolling friction, so that the thrust is greatly reduced, which is convenient for the operator to push and use, reduces the operator's workload, and improves the overall use quality and effect of the device.

[0040] (2) The roller of the new drum door is filled with lubricating liquid into the oil tank 14 through the oil inlet pipe 18. When the double-mounted bearing 4 and the wheel axle 5 need to be lubricated, the liquid pump 15 is started by the microcontroller, and the lubricating liquid in the oil tank 14 is pumped into the liquid guide pipe 16 through the connecting pipe, and sprayed through the nozzle 17, thereby reducing the wear of the double-mounted bearing 4 and the wheel axle 5, improving the quality of the double-mounted bearing 4 and the wheel axle 5, and thus increasing the service life of the entire device. The sealing cover 11 and the protective oil seal 9 can seal the roller body 1, reducing the lubricating oil from overflowing from the roller body 1 through the opening or groove.
