[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0032] Example 1: Figures 1 to 6 As shown, an intelligent hanging conveying system for clothing production according to an embodiment of the present invention comprises a track 1, a chain is provided in the track 1, and a group of hooks 2 are fixedly connected to the chain; a storage box 3 is provided on the track 1, and lubricating oil is stored in the storage box 3, and the top surface of the storage box 3 is connected to a liquid inlet pipe 4; the bottom surface of the storage box 3 is connected to a discharge pipe 5, and a chute 7 is provided on the bottom surface of the discharge pipe 5, and an adjusting pipe 6 is slidably connected in the chute 7, and the bottom surface of the adjusting pipe 6 is in contact with the chain, and the bottom surface of the adjusting pipe 6 is provided with a liquid outlet component for discharging lubricating oil; a magnetic block 9 is provided on the adjusting pipe 6, and an electromagnet 10 that repels the magnetic block 9 is fixedly connected to the top surface of the inner wall of the chute 7, and an elastic rope 8 is provided between the adjusting pipe 6 and the inner wall of the chute 7;

[0033] The track 1 in the present application can intelligently move the hook 2 in a regular manner. Clothes are hung on the hook 2 and move continuously for intelligent hanging transportation. The electromagnet 10 is set to start once every 15 days, and the start time is three minutes. When the electromagnet 10 is started, the electromagnet 10 will push the magnet, so that the magnet drives the discharge pipe 5 to move downward, so that the bottom surface of the discharge pipe 5 fits with the chain. At this time, the liquid discharge component can discharge the lubricating oil onto the chain to achieve the effect of lubricating the chain, reduce the friction coefficient of the contact surface between the chain and the track 1, and improve the service life of the overall equipment.

[0034] The liquid outlet component includes a liquid outlet groove 11 provided on the bottom surface of the regulating tube 6, and the inner wall of the liquid outlet groove 11 is sealed and rotatably connected to a circular shaft 12, and a group of grooves 13 are provided on the surface of the circular shaft 12; after the regulating tube 6 in the present application moves downward, the circular shaft 12 will contact the chain. At this time, when the chain is running, it will drive the circular shaft 12 to rotate, so that the grooves 13 can dig the lubricating oil in the regulating tube 6 onto the chain, so that the lubricating oil can flow accurately to the chain, thereby achieving the effect of saving the use of lubricating oil.

[0035] A hollow groove 14 is provided in the circular shaft 12, and a counterweight 15 is fixedly connected to the inner wall of the hollow groove 14; after the electromagnet 10 in the present application is closed, the elastic rope 8 will pull the adjusting tube 6 to move upward. At this time, the center of gravity of the circular shaft 12 is downward due to the counterweight 15 to prevent the circular shaft 12 from rotating due to external force during equipment transportation, which causes the lubricating oil to flow out.

[0036] A movable groove 16 is provided on the top surface of the regulating tube 6, and a push plate 17 is sealingly and slidably connected to the inner wall of the movable groove 16. A group of first springs 18 are fixedly connected between the bottom surface of the push plate 17 and the inner wall of the movable groove 16. An air intake pipe 19 is connected to the movable groove 16, and the end of the air intake pipe 19 away from the movable groove 16 is connected to a hollow block 20. The bottom surface of the hollow block 20 is provided with multiple groups of circular holes (not shown in the figure). The hollow block 20 is installed in the track 1 through a bracket and is located above the chain. The magnetic block 9 is fixedly mounted on the top surface of the push plate 17;

[0037] When the electromagnet 10 in the present application pushes the magnetic block 9, the magnetic block 9 will drive the adjusting tube 6 to move downward so that the circular shaft 12 contacts the chain, and then the magnetic force of the electromagnet 10 gradually increases, and then decreases. When the magnetic force of the electromagnet 10 increases, it will continue to increase the thrust on the magnetic block 9. At this time, the gas in the movable groove 16 will be discharged from the air outlet pipe 21 into the hollow block 20. At this time, the gas will be blown from the circular hole onto the chain to blow away the dust and impurities on the chain, and then the chain will be lubricated by passing through the circular shaft 12. When the magnetic force of the electromagnet 10 decreases, the first spring 18 will push the push plate 17 to move upward for reset.

[0038] The movable groove 16 is connected to an air outlet pipe 21, and the air inlet pipe 19 is provided with an air inlet one-way valve, and the air outlet pipe 21 is provided with an air outlet one-way valve; when the push plate 17 in the present application moves downward, the gas in the movable groove 16 will be discharged from the air outlet pipe 21, and the gas will be discharged from the air outlet pipe 21 and will not be blown onto the chain. When the push plate 17 moves upward, the movable groove 16 will inhale gas from the air inlet pipe 19, and the circular hole will absorb the impurities on the chain, thereby sucking the impurities into the movable groove 16 for storage to prevent the impurities on the chain from being blown onto the clothes.

[0039] The air outlet pipe 21 is fixedly connected to a connecting pipe at one end of the movable groove 16, and a filter screen 23 is fixedly connected to the surface of the connecting ring 22; dust and impurities will be stored in the movable groove 16 in the present application, and when the gas in the movable groove 16 is discharged from the air outlet pipe 21, the impurities in the gas will be filtered by the filter screen 23 to prevent dust and impurities from being discharged from the air outlet pipe 21 again and falling onto the chain.

[0040] The bottom surface of the adjusting tube 6 is provided with a discharge trough 24 connected to the movable groove 16, and the inner wall of the discharge trough 24 is fixedly connected with a guide rod 26, and a sealing plate 25 for sealing the discharge trough 24 is sealingly and slidingly connected on the guide rod 26, and a circular ring 27 is fixedly connected to the surface of the guide rod 26, and a second spring 28 is fixedly connected between the circular ring 27 and the sealing plate 25; the dust and impurities stored in the movable groove 16 in the present application can be discharged from the discharge trough 24. When the dust and impurities need to be discharged in a centralized manner, the sealing plate 25 can be manually moved downward so that the sealing plate 25 no longer seals the discharge trough 24. At this time, the worker can use a dust collection box to be placed under the discharge pipe 5 to catch the discharged dust. After the dust is discharged, the sealing plate 25 is released. At this time, the second spring 28 will pull the sealing plate 25 to reset to continue to seal the discharge trough 24.

[0041] Example 2: Figure 7 As shown, compared with Example 1, another implementation of the present invention is: the top of the storage box 3 is fixedly connected to the alarm 32, the inner wall of the storage box 3 is slidably connected to the float 29, the bottom surface of the float 29 is fixedly connected to the pressure plate 30, and the bottom surface of the inner wall of the storage box 3 is fixedly connected to the pressure sensor 31 corresponding to the pressure plate 30, and the pressure sensor 31 is used to start the alarm 32; in this application, the lubricating oil in the storage box 3 will gradually decrease during use, and the float 29 will also follow the decline. When the pressure plate 30 contacts the pressure sensor 31, the pressure sensor 31 will automatically start the alarm 32 to alarm, so as to remind the staff that the lubricating oil is insufficient and needs to be added in time.

[0042] like Figure 8 As shown, a control method for an intelligent hanging conveying system for clothing production is provided. The method is used to control the intelligent hanging conveying system for clothing production. The method comprises the following steps:

[0043] S1: Automatically detects the status of all chains, motors, sensors, and communication modules at startup, automatically generates a device health report, and uses the motor to drive the chain to run within track 1;

[0044] S2: Clothes are hung on hook 2 via hangers. Each piece of clothing is attached with a unique identification tag for real-time tracking. Photoelectric sensors are used to detect hanger position and flow, and environmental sensors are used to detect temperature and humidity to ensure a safe production environment.

[0045] S3: Lubricate the chain regularly and set the electromagnet 10 to start once every 15 days for three minutes. When the electromagnet 10 starts, it pushes the magnet, causing the magnet to drive the circular shaft 12 to fit the chain.

[0046] S4: When the chain is running, it will drive the circular shaft 12 to rotate, so that the groove 13 on the circular shaft 12 will dig the lubricating oil in the regulating tube 6 onto the chain for precise lubrication.

[0047] Working principle: By starting the electromagnet 10 to push the magnetic block 9, the magnetic block 9 drives the discharge pipe 5 to move downward so that the bottom surface of the discharge pipe 5 fits with the chain. At this time, the liquid discharge component can discharge the lubricating oil onto the chain to achieve the effect of lubricating the chain, reducing the friction coefficient of the contact surface between the chain and the track 1, and improving the service life of the entire equipment; after the adjusting tube 6 moves downward, the round shaft 12 will contact the chain. At this time, when the chain is running, it will drive the round shaft 12 to rotate, so that the groove 13 can dig the lubricating oil in the adjusting tube 6 onto the chain, so that the lubricating oil can flow accurately to the chain, achieving the effect of saving the use of lubricating oil; after the electromagnet 10 is closed, the elastic rope 8 will pull the adjusting tube 6 to move upward. At this time, the center of gravity of the round shaft 12 is downward due to the counterweight block 15 to prevent the round shaft 12 from rotating due to the external force during equipment transportation, causing the lubricating oil to flow out;

[0048] When the electromagnet 10 in the present application pushes the magnetic block 9, the magnetic block 9 will drive the regulating tube 6 to move downward so that the circular shaft 12 contacts the chain, and then the magnetic force of the electromagnet 10 gradually increases, and then decreases. When the magnetic force of the electromagnet 10 increases, it will continue to increase the thrust on the magnetic block 9. At this time, the gas in the movable groove 16 will be discharged from the air outlet pipe 21 into the hollow block 20. At this time, the gas will be blown onto the chain from the circular hole to blow away the dust and impurities on the chain. Then the chain will be lubricated by the circular shaft 12. When the magnetic force of the electromagnet 10 decreases, the first spring 18 will push the push plate 17 to move upward for reset; the push plate 17 in the present application moves upward. When the chain moves downward, the gas in the movable groove 16 will be discharged from the air outlet pipe 21. At this time, the gas will be discharged from the air outlet pipe 21 and will not be blown onto the chain. When the push plate 17 moves upward, the movable groove 16 will inhale gas from the air inlet pipe 19. At this time, the circular hole will absorb the impurities on the chain, thereby sucking the impurities into the movable groove 16 for storage to prevent the impurities on the chain from being blown onto the clothes. Dust and impurities will be stored in the movable groove 16 in this application. When the gas in the movable groove 16 is discharged from the air outlet pipe 21, the impurities carried in the gas will be filtered by the filter 23 to prevent the dust and impurities from being discharged from the air outlet pipe 21 again and falling onto the chain.

[0049] In the present application, the dust and impurities stored in the movable trough 16 can be discharged from the discharge trough 24. When the dust and impurities need to be discharged in a centralized manner, the sealing plate 25 can be manually moved downward so that the sealing plate 25 no longer seals the discharge trough 24. At this time, the worker can use a dust collection box to be placed under the discharge pipe 5 to catch the discharged dust. After the dust is discharged, the sealing plate 25 is released. At this time, the second spring 28 will pull the sealing plate 25 to reset to continue sealing the discharge trough 24.
