The outer side of the body has a chrome-plated layer. It also includes a connecting shaft, a positioning pin 1, a positioning pin 2 and a spring. The above-mentioned connecting shaft passes through the body and both ends of the connecting shaft extend out of the body. The connecting shaft has a through connecting hole. The inner ends of the above-mentioned positioning pin 1 and positioning pin 2 and the spring are all located in the connecting hole. The inner side of the above-mentioned body has recessed positioning notches 1 and 2. Under the elastic force of the spring, the outer end of the positioning pin 1 has a tendency to be embedded in the positioning notch 1, and the outer end of the positioning pin 2 has a tendency to be embedded in the positioning notch 2;

[0004] In the above technical solution, the positioning pin 1, the positioning pin 2 and the spring are connected at the connecting hole of the connecting shaft. Under the elastic force of the spring, the outer end of the positioning pin 1 extends out of the connecting shaft and is embedded in the positioning notch 1. At the same time, the outer end of the positioning pin 2 extends out of the connecting shaft and is embedded in the positioning notch 2. This structure stably connects the connecting shaft and the body, improving the equipment stability; however, in actual use, there is no protective device on the outer surface of the chrome-plated roller body. The chrome-plated roller body is easily corroded and damaged, and its service life is low. At the same time, making a solid chrome-plated roller body consumes a lot of materials and is expensive. In addition, due to friction during the use of the chrome-plated roller, metal thermal expansion will occur, causing changes in dimensions and affecting the production process. Utility Model Content

[0043] Specifically, a roller body sleeve assembly 2 is provided on the outer surface of the roller body 1. The roller body sleeve assembly 2 includes an upper roller sleeve 20 and a lower roller sleeve 21. At the bottom end of the upper roller sleeve 20 near the four corners, first perforations 200 are provided. At the corresponding positions at the bottom end of the lower roller sleeve 21, second perforations 210 are provided. At the corresponding positions of the first perforations 200 and the outer surface of the roller body 1, screw holes 100 are provided. Screws 211 are provided on the second perforations 210. The screws 211 pass through the first perforations 200, the second perforations 210 and are threadedly connected with the screw holes 100. Outer grooves 202 are provided on both sides at the bottom end of the upper roller sleeve 20, and inner grooves 212 are provided on both sides at the top end of the lower roller sleeve 21. The outer grooves 202 and the inner grooves 212 are inserted and matched and fit tightly.

[0044] In the present utility model, the roller body sleeve assembly 2 is made of corrosion-resistant alloy steel, and at the same time, the roller body sleeve assembly 2 is chrome-plated to increase the corrosion resistance of the roller body sleeve assembly 2. The screws 211 cooperate with the first perforations 200, the second perforations 210 and the screw holes 100 to fix the upper roller sleeve 20 and the lower roller sleeve 21, and at the same time fix the upper roller sleeve 20 and the lower roller sleeve 21 on the outer surface of the roller body 1.

[0048] In the present utility model, by providing the roller body compartment 12, the consumption of the roller body 1 is reduced, and the production cost is lowered. At the same time, by providing a plurality of support frames 13 in the roller body compartment 12, the structural stability of the roller body compartment 12 is increased, and the overall rigidity of the roller body 1 is improved. By providing support grooves 131 distributed at equal intervals, the filled coolant 14 is evenly distributed in the roller body compartment 12, avoiding uneven temperature in each area of the roller body compartment 12 caused by uneven distribution of the coolant 14.

[0049] It should be noted that a support hole 130 is provided at the center of the support frame 13, and the radius of the support hole 130 is larger than the radius of the roller core 3.

[0050] In the present utility model, by providing the support hole 130 and the radius of the support hole 130 being larger than the radius of the roller core 3, the roller core 3 can extend from one end roller body hole 11 through the support frame 13 to the other end roller body hole 11, and at the same time, without affecting the supporting ability of the support frame 13, the production cost of the support frame 13 is reduced.

[0052] In the present utility model, by filling the coolant 14 inside the roller body compartment 12, the heat generated during the operation of the roller body 1 is absorbed, avoiding thermal expansion of the metal and affecting the production process of the roller body 1.

[0053] When a corrosion-resistant chrome-plated roller in this embodiment is in use, the user first welds the outer wall of the support frame 13 to the inner wall of the roller body compartment 12, injects the coolant 14 into the roller body compartment 12 through the roller body hole 11, extends the roller core 3 from one end roller body hole 11 to the other end roller body hole 11, welds and fixes the roller core 3 to the roller body 1, fits the upper roller sleeve 20 on the upper surface of the roller body 1, fits the lower roller sleeve 21 on the lower surface of the roller body 1, determines the position of the roller sleeve assembly 2 on the outer surface of the roller body 1 through the positions of the protrusion 201 and the groove 10, sequentially passes the screw 211 through the first through hole 200 and the second through hole 210 and threads it with the screw hole 100, and passes the bolt 31 through the third through holes 30 on both sides of the roller core 3 and tightens the bolt 31;

[0054] When an anti-corrosion chromium-plated roller needs to be used, first, the user needs to check the connection status between the roller body 1 and the roller sleeve assembly 2. When the connection between the roller body 1 and the roller sleeve assembly 2 is not firm, tighten the screw 211. At the same time, check the flatness of the outer surface of the roller sleeve assembly 2. When there are pits or unevenness on the outer surface of the roller sleeve assembly 2, promptly repair and replace the roller sleeve assembly 2. After the inspection, move the roller body 1 to the workbench, insert and fit the roller core 3 with the output shaft of the output device, fix the bolt 31 on the third perforation 30 to fix the roller core 3 and the output device, and then the roller body 1 can start working;

[0055] When the roller sleeve assembly 2 is corroded and damaged later, unscrew the screw 211, separate the upper roller sleeve 20 and the lower roller sleeve 21 from the roller body 1. When the coating on the outer surface of the roller sleeve assembly 2 is damaged, use chromium plating technology to re-chrome the roller sleeve assembly 2 to repair the coating of the roller sleeve assembly 2. When the outer surface of the roller sleeve assembly 2 is damaged, replace the roller sleeve assembly 2. Re-sleeve the repaired or replaced roller sleeve assembly 2 on the outer surface of the roller body 1 and fix it with the screw 211, and then the roller body 1 can start working again.
