Description

Technical Field

[0001] This utility model relates to the technical field, and in particular to a self-cleaning and wear-resistant guide wheel device. Background Technology

[0002] Guide wheels are widely used in various mechanical equipment in many fields such as industrial manufacturing, logistics warehousing, and automated production lines. They play a crucial role in guiding the movement trajectory of objects and ensuring the stable operation of equipment. However, traditional guide wheels face many challenges in practical applications.

[0003] Because the guide wheels are in a complex working environment for a long time, dust, debris, oil and other impurities easily adhere to the wheel surface and accumulate thick dirt. These impurities not only affect the rotation flexibility of the guide wheels and cause the equipment to jam, but also require manual disassembly and cleaning at regular intervals. This not only consumes a lot of manpower, material resources and time, but frequent disassembly may also damage the guide wheels and related components, affecting the overall service life of the equipment.

[0004] On the other hand, under high load and high speed operating conditions, friction between the guide wheel and the track or other contact parts is inevitable. The guide wheel is difficult to withstand long-term frictional wear, and the wheel surface wears quickly. Moreover, the lubrication methods of traditional guide wheels are mostly rough and cannot provide precise lubrication according to the actual working conditions, which will further aggravate the wear of the guide wheel. Utility Model Content

[0012] Preferably, one end of the oil inlet and the oil outlet is provided with a sealing valve.

[0013] Preferably, the cleaning brush is provided with a clamping groove on the side close to the main guide wheel.

[0027] EMBODIMENT

[0028] REFERENCE Figures 1-4A self-cleaning and wear-resistant guide wheel device includes a base 1, a guide wheel shaft 2 on one side of the base 1, a main guide wheel 3 sleeved on the outside of the guide wheel shaft 2, a base 4 fixedly connected to the inner bottom of the main guide wheel 3, an electric push rod 5 on the base 4, a connecting rod 6 connected to the output end of the electric push rod 5, a support plate 7 fixedly connected to the top of the connecting rod 6, a micro motor 8 on the support plate 7, a transmission shaft 9 connected to the output end of the micro motor 8, a connecting plate 10 fixedly connected to the top of the transmission shaft 9, and a telescopic bushing 11 fixedly connected to one side of the connecting plate 10.

[0029] The inner wall of the main steering wheel 3 is provided with a storage groove 12, and a cleaning brush 13 is provided in the storage groove 12. A positioning shaft 14 is fixedly connected to the side of the cleaning brush 13 near the telescopic bushing 11. A positioning hole that cooperates with the positioning shaft 14 is provided at one end of the telescopic bushing 11.

[0030] A miniature air pump 15 is installed on the base 4. The output end of the miniature air pump 15 is connected to an airflow pipe 16. One end of the airflow pipe 16 extends to the outer top of the main steering wheel 3 and is fixedly connected to an annular channel 17. Several nozzle holes 18 are opened at the bottom of the annular channel 17. The nozzle holes 18 and the airflow pipe 16 are connected to the interior of the annular channel 17 and form an airflow channel. An airflow regulating valve 19 is installed at the end of the airflow pipe 16 near the miniature air pump 15.

[0031] The inner wall of the main guide wheel 3 is provided with several oil storage chambers, each consisting of several tiny oil storage holes. An oil outlet hole 20 is provided inside the oil storage hole, with one end of the oil outlet hole 20 extending and abutting against the surface of the guide wheel shaft 2.

[0032] The top of the main steering wheel 3 is provided with an oil inlet 21 and the bottom is provided with an oil outlet 22. One end of the oil inlet 21 and the oil outlet 22 extends into the oil storage cavity and communicates with the oil outlet 20 to form an oil flow channel.

[0033] A sealing valve 23 is provided at one end of both the oil inlet 21 and the oil outlet 22.

[0034] The cleaning brush 13 has a slot on the side near the main guide wheel 3.

[0035] In this implementation scheme, when the surface of the main guide wheel 3 becomes dirty after a period of use and needs cleaning, the cleaning brush 13 is first removed from the storage slot 12. Then, the electric push rod 5 is activated. When the electric push rod 5 is running, it drives the connecting rod 6 to rise. When the connecting rod 6 rises, it drives the connecting plate 10 to rise to the top surface of the main guide wheel 3. Then, the telescopic bushing 11 is pulled, and the positioning shaft 14 on one side of the cleaning brush 13 is inserted into the positioning hole in the telescopic bushing 11, thereby completing the installation of the cleaning brush 13, so that the cleaning brush 13 fits against the surface of the main guide wheel 3. Then, the micro motor 8 is activated. When the micro motor 8 is running, it drives the transmission shaft 9 and the connecting plate 10 to rotate. When the connecting plate 10 rotates, it drives the telescopic bushing 11 and the cleaning brush 13 to rotate. Thus, when the cleaning brush 13 rotates along the surface of the main guide wheel 3, it can clean the dirt attached to the surface of the wheel without the need to disassemble and clean the main guide wheel 3 as a whole.

[0036] Specifically, after cleaning the surface of the main guide wheel 3, the cleaning brush 13 can be removed from the positioning hole and disassembled. Then, the above operation is reversed to complete the storage of the cleaning brush 13, so as not to affect the normal operation of the main guide wheel 3. At this time, the airflow regulating valve 19 can be activated. Then, the high-pressure airflow in the micro air pump 15 flows through the airflow pipe 16 through the annular channel 17 and is ejected from the nozzle hole 18 through the airflow channel, thereby forming an air curtain around the main guide wheel 3. At this time, the air curtain can blow away the impurities close to the wheel surface when the main guide wheel 3 is working. At the same time, as the main guide wheel 3 rotates, the airflow can also carry away some of the dust and debris adhering to the wheel surface, thereby realizing the continuous self-cleaning of the main guide wheel 3.

[0037] Furthermore, after cleaning the main guide wheel 3, the sealing valve 23 can be opened to add lubricant to the oil inlet 21. The lubricant then flows through the oil outlet 20 and the oil flow channel. When the main guide wheel 3 rotates, under the action of centrifugal force and the relative motion between the main guide wheel 3 and the guide wheel shaft 2, the lubricant in the oil flow channel gradually seeps out through the oil outlet 20 to lubricate the contact part between the main guide wheel 3 and the guide wheel shaft 2, reducing the wear of the main guide wheel 3. When it is necessary to replace the lubricant or clean the oil reservoir, the old lubricant is discharged through the oil outlet 22, and then the sealing valve 23 is closed to prevent the leakage of new lubricant inside the main guide wheel 3.
