The diameter of the plug ball 84 is larger than the inner diameter of the rope hole 65, so that the plug ball 84 can block the rope hole 65 after moving to the right. The elastic pull rope 82 is in an extended state, and the diameter of the warning color ball 87 is smaller than the inner diameter of the rope hole 65, so that the warning color ball 87 can easily pass through the rope hole 65. The bent tail of the hook 83 is round, so that the hook 83 will not hook the ring groove 67.

[0042] Workflow: the corrosion-resistant high-temperature sealing effect of the roller in the steel plate vertical pickling equipment installation, sealing operation as follows, must know one: the roller in the equipment in the steel plate vertical pickling equipment use, roller sleeve 1 in pickling tank, mainly responsible for the movement of the straight steel plate guide, PPH sealing part 2 is located in the pickling tank, part of the pickling tank, specifically, the inner sealing ring 21 and part of the outer sealing sleeve 23 in the pickling tank, while the remaining outer sealing sleeve 23, cover 24 and the roller shaft 4 right end bare part is located in the pickling tank, the position of the whole roller through the bearing seat 10 and fastening bolt fixed; must know two: inner sealing ring 21, outer sealing sleeve 23 and spacer sleeve 66 are made of PPH material, and acid-proof folding air bag 75 is made of TPU air bag cloth, which has excellent acid corrosion resistance; must know three: according to user demand, can choose by easy to be corroded material made of plastic ring belt, such as polystyrene, polycarbonate, polyamide, polylactic acid, etc., these materials can be used as easy to be eroded plastic ring belt 85; must know four: the reset of the pressing module 7 of the pressing part 76, first remove the cover 24, expose the pressing module 7 in the outer sealing sleeve 23, at this time can move the locking pin 773 by pulling the reset pull piece 772, make the locking pin 773 away from one of the pin slot 764, make the one-way locking part 77 no longer lock the pressing part 76, at this time the staff can reset the pressing part 76 back to the original position; roller assembly operation: in the assembly operation of the roller, the roller can be roughly divided into three main parts, the first part includes the roller sleeve 1 and the flow guide tightening part 3, the second part is the PPH sealing part 2, and the third part is composed of the roller shaft 4 and the rotation driver 5, the inner support part 6, the pressing module 7 and the leakage warning part 8 on the roller shaft 4; first, the PPH sealing part 2 needs to be sleeved on the outside of the sleeve body 11 of the roller sleeve 1 from the right side, in this step, it is necessary to ensure that the inner sealing ring 21 is inserted into the sealing ring insertion slot 13, and tightly fit with the outer curved surface of the right joint sleeve of the sleeve body 11, at the same time, the left end face of the outer sealing sleeve 23 also needs to fit with the right end face of the right convex ring of the sleeve body 11, in order to complete the installation between the PPH sealing part 2 and the roller sleeve 1;Next, the shaft body 41 of the roller shaft 4 is displaced to the left, so that it passes through the inner sealing ring 21 of the PPH sealing part 2 and is inserted into the shaft cavity 12 of the sleeve body 11. In this process, the roller shaft 4 drives the compression module 7 and the leakage warning part 8 into the PPH sealing part 2 through the inner support part 6. With the left displacement of the shaft body 41, the flow guide and tightening part 3 is inserted into the matching channel 43 of the roller shaft 4, and the lead screw 52 is butted against the lead sleeve 35. At this time, by rotating the rotating block 53 and the rotating shaft 51, the lead screw 52 can be driven to rotate and be threadedly connected with the lead sleeve 35. With the rotation of the lead screw 52, the left displacement is realized. The left displacement of the rotating driving part 5 drives the entire roller shaft 4 to displace to the left, i.e. to the depth of the shaft cavity 12. Since the diameter of the left end of the roller shaft 4 is the same as the inner diameter of the shaft cavity 12, the outer curved surface of the left end of the shaft body 41 is tightly fitted with the inner curved surface of the shaft cavity 12. Therefore, the left displacement of the roller shaft 4 can extrude the gas in the shaft cavity 12, so that the gas enters the pipe shell 31 from the air hole 32 of the flow guide and tightening part 3, then passes through the flow guide pipe 34 into the matching channel 43 of the roller shaft 4, and is then shunted through the air channels 44, so that the gas flow enters the compression modules 7. The gas flow is transferred through the transfer shell 71 into the acid-proof folding air bags 75, so that the acid-proof folding air bags 75 are inflated and expanded to the left, tightly abutting against the inner sealing ring 21, so that the PPH sealing part 2 is tightly fitted with the roller sleeve 1 without any gap. After the above steps are completed, the positioning tight bolts 9 can be placed into the bolt installation pipe 63 from the dismounting hole 62, and the positioning tight bolts 9 are threadedly connected with the threaded holes 14 through the perforations 22 in cooperation with the external tool screwdriver, so that the three parts are fastened together, ensuring that the PPH sealing part 2 is tightly fitted with the roller sleeve 1. Finally, the roller shaft 4 is installed into the bearing seat 10, and the assembly operation of the roller is completed. The structure of the roller after the assembly is completed is as follows; Figures 1-5The sealing operation: in the pickling tank of the pickling equipment, the position of the roller and the sealing operation are very important. According to the knowledge of the position of the roller in the pickling tank, the PPH sealing part 2 of the roller is designed to cooperate with the roller sleeve 1 in the pickling tank to protect the roller shaft 4 in the pickling tank, and to ensure that there is no gap to prevent the acid liquid in the pickling tank from causing corrosion damage to the roller shaft 4. This sealing is achieved by the close cooperation between the left end face of the inner sealing ring 21 and the sealing ring slot 13, and the close cooperation between the inner curve of the inner sealing ring 21 and the outer curve of the right joint sleeve of the sleeve body 11. However, if the PPH sealing part 2 has a gap between the roller sleeve 1 due to the loosening or wear of the positioning tight bolt 9, the acid-proof folding air bag 75 will have a surplus to further elongate. In the actual use of the roller, the rotation of the roller sleeve 1 and the roller shaft 4 will drive the tight pressing module 7 to rotate through the inner support part 6. The existence of the surplus in cooperation with the centrifugal force in rotation will throw the counterweight block 763 outward, and the displacement of the counterweight block 763 will drive the pressing strip 761 to displace through the connecting rod 762, so as to extrude the acid-proof folding air bag 75 and force it to further elongate, thereby pushing the PPH sealing part 2 to displace to the left and making it tightly fit with the roller sleeve 1 without leaving a gap. At the same time, the displacement of the connecting rod 762 will drive each pin slot 764 to displace, and the one-way locking part 77 will automatically enter the next pin slot 764 through the elastic reset of the spring 774, so as to position the pressing part 76. The cooperation between the semicircular structure of the pin 773 and the semicircular card slot of the pin slot 764 makes the connecting rod 762 only displace in one direction and cannot reset itself, ensuring that the pressing part 76 can only displace in one direction without human operation, and further ensuring the elongation size of the acid-proof folding air bag 75 and further positioning the position of the PPH sealing part 2. Through the above operation, the sealing operation is completed, and the corrosion-resistant and high-temperature roller for steel plate vertical pickling equipment realizes automatic continuous fastening of the sealing mechanism through its rotation in the use process, ensuring that the sealing mechanism is always tightly fitted with the roller sleeve 1 without leaving a gap, so as to achieve the effect of prolonging and improving the sealing effect. This solves the problem that the existing corrosion-resistant and high-temperature roller for steel plate vertical pickling equipment is prone to have a gap between the sealing mechanism and the roller sleeve 1 due to the loosening or wear of the fastener in the use process, so that the acid liquid has the opportunity to penetrate through these gaps and further cause corrosion damage to the roller shaft 4.Leakage warning operation: When a seal failure causes a gap to appear, acid may pass through the gap between the inner sealing ring 21 of the PPH sealing part 2 and the right connecting sleeve of the sleeve body 11 and enter the spacer 66. In this case, the function of the spacer 66 is to separate the acid from the roller 4 and prevent the acid from directly contacting the roller 4. The acid will first come into contact with the easily corroded plastic ring 85. Since this ring is designed to be made of easily corroded material, it will be quickly corroded and broken. As the easily corroded plastic ring 85 is corroded and broken, the elastic pull rope 82, which was originally positioned by it, will change from an extended state to a retracted state, quickly pulling the plug ball 84, hook 83 and warning colored ball 87 to the right. The rightward movement of the plug ball 84 will block the rope hole 65, thereby preventing leakage. The leaking acid is sealed within the cavity formed by the PPH sealing part 2 and the inner support part 6, preventing further spread of the acid. Simultaneously, the warning ball 87 will pass through the rope hole 65 and move to the right side of the base ring 61. When patrolling personnel see the warning ball 87, it indicates that the seal between the PPH sealing part 2 and the roller sleeve 1 has failed, requiring immediate inspection and maintenance. Through this series of steps, the leak warning operation is completed. This design can promptly warn personnel of acid leaks, preventing prolonged leakage from causing greater damage to the roller. This leak warning mechanism not only improves equipment safety but also helps maintenance personnel to promptly detect and handle problems, thereby reducing the risk of equipment damage and production interruptions.
