[0002] In the field of mechanical engineering, rollers are a common mechanical component, widely used in various mechanical equipment, such as printing machines, paper machines, textile machines, etc. The quality of rollers directly affects the operating efficiency and product quality of mechanical equipment. Traditional rollers are usually made of steel, which has the advantages of high strength and wear resistance, but the disadvantages are heavy weight and high energy consumption, which is not conducive to the high-speed operation of mechanical equipment. With the development of materials science, new materials such as carbon fiber materials and aluminum alloy materials are gradually being used in the manufacture of rollers. Carbon fiber materials have the advantages of light weight, high strength, and corrosion resistance, which can effectively reduce the weight of rollers and improve the operating efficiency of mechanical equipment. Aluminum alloy materials have good corrosion resistance and machinability, which can increase the service life of rollers.

First, although carbon fiber materials and aluminum alloy materials can reduce the weight of the roller, the cost is high, which increases the manufacturing cost of mechanical equipment. Secondly, in the existing solutions, the dynamic balance value of the roller is not high, which easily causes vibration of the mechanical equipment during operation, affecting the quality and production efficiency of the product. Finally, the surface of the existing roller wears quickly during use and needs to be replaced regularly, which increases the maintenance cost. Utility Model Content

[0033] The utility model adopts carbon fiber material and aluminum alloy material to make the roller, which can significantly reduce the weight of the roller compared to the traditional steel roller, thereby reducing the energy consumption of mechanical equipment and improving the operating efficiency. In addition, although the cost of carbon fiber material and aluminum alloy material is relatively high, the roller design of the utility model can effectively reduce the weight of the roller, thereby reducing the energy consumption of mechanical equipment and improving the operating efficiency, so in the long-term operation, a lot of energy consumption and maintenance costs can be saved.

[0034] In some embodiments, the roller core 1 is made of T700 carbon fiber, which can significantly reduce the weight of the roller compared to traditional steel rollers.

[0035] In some embodiments, the outer roller 2 is made of 6065 aluminum alloy, which reduces the weight of the entire roller while also having a certain wear resistance.

[0036] In some embodiments, the shaft head 3 is made of 42CrMo steel. Due to the wear resistance and corrosion resistance of 42CrMo steel, the service life of the roller can be effectively extended and the maintenance cost can be reduced.

[0037] In some embodiments, the roller core 1 and the outer roller 2 are in interference fit, so that the roller has better stability and wear resistance.

[0038] In some embodiments, the roller core 1 has a length of 1120 mm, an outer diameter of 67 mm, an inner diameter of 60 mm, and is lighter in weight.

[0039] In some embodiments, the outer roller 2 has an outer diameter of 70 mm and an inner diameter of 67 mm, and is lighter in weight.

[0040] In some embodiments, the length of the shaft head 3 is 71 mm. This design not only improves the dynamic balance value of the roller and reduces the vibration of the mechanical equipment during operation, but also improves the product quality and production efficiency.

[0041] In some embodiments, the outer surface of the outer roller 2 has a coating, which maintains the wear-resistant property, can extend the service life of the roller, and reduce maintenance costs.

[0042] In some embodiments, the plating layer is made of chrome, which has better wear resistance.

[0043] In some embodiments, a method for manufacturing the above-mentioned lightweight guide roller is also provided, comprising the following steps:

[0044] Step 1: Select a 6065 aluminum alloy tube with an outer diameter of 70mm, an inner diameter of 60mm and a length of 6065mm as the main body of the old roller. Put the aluminum alloy tube into the lathe and turn out 81mm long shaft heads at both ends according to the designed size.

[0045] Step 2: Select a T700 carbon fiber rod with a length of 1120mm, an outer diameter of 67mm, and an inner diameter of 60mm as the roller core of the new roller. Put the carbon fiber rod into the lathe and turn out 71mm long shaft heads at both ends according to the designed size.

[0046] Step 3: Put the old roller obtained in step 1 and the new roller obtained in step 2 into a heating furnace, set the furnace temperature at 400°C, and keep it warm for 2 hours, so that the shaft heads of the old roller and the new roller expand due to the heat.

[0047] Step 4: Take out the old roller and the new roller that have been heated in step 3 quickly, and quickly put the new roller on the outside of the old roller to form a composite roller. At this time, since the shaft heads of the old roller and the new roller are in a state of thermal expansion, the new roller can be easily put on the outside of the old roller.

[0048] Step 5: Put the composite roller obtained in step 4 into the heating furnace again, set the furnace temperature at 500° C., and keep it warm for 1 hour, so that the shaft head of the composite roller can further expand due to the heat.

[0049] Step 6: Take out the composite roller heated in step 5 quickly, and quickly put a 6065 aluminum alloy tube with an outer diameter of 70mm and an inner diameter of 67mm on the outside of the composite roller to form the final roller. At this time, since the shaft head of the composite roller and the aluminum alloy tube are in a state of thermal expansion, the aluminum alloy tube can be easily put on the outside of the composite roller.

[0050] Step 7: Place the final roller obtained in step 6 into a cooling furnace, set the furnace temperature at room temperature, and cool for 2 hours, so that the shaft head and the aluminum alloy tube of the final roller cool and shrink, thereby fixing the aluminum alloy tube to the outside of the composite roller through interference fit.

[0051] Step 8: Chrome plating is performed on the roller surface of the final roller to maintain its wear resistance. The parameters of chrome plating are: current density is 2A / dm 2 , the pH value of the electrolyte is 2, the temperature of the electrolyte is 50°C, and the electrolysis time is 30 minutes.

[0052] Through the above steps, a lightweight and highly dynamically balanced guide roller using a carbon fiber roller core and a 6065 aluminum alloy tube can be obtained, which not only reduces the weight of the roller and improves the dynamic balance value, but also maintains the wear resistance, prolongs the service life, and reduces the manufacturing cost.
