Description

Technical Field

[0001] The utility model relates to the field of machinery, in particular to a roller, in particular to an improved carbon fiber rubber roller. Background Art

[0002] Carbon fiber rubber rollers have been widely used in printing, textile, food processing and other industries due to their high strength, light weight and wear resistance. However, in practical applications, the slender carbon fiber rubber rollers have some disadvantages in terms of deflection, which will affect the processing accuracy, quality, service life, energy consumption, equipment vibration and noise, and restrict the further promotion and application of carbon fiber rubber rollers.

[0003] Specifically, first, due to the excessive deflection of the roller body, there will be a gap between the roller and the workpiece being processed, affecting the processing accuracy. For example, in the printing industry, carbon fiber rubber rollers are used for embossing rollers and transmission rollers of high-speed printing machines. If the deflection of the roller body is too large, the printed image will be blurred, ghosting and other problems will occur, reducing the printing accuracy. Second, the deflection will cause friction between the roller and the workpiece being processed, aggravating the wear of the roller and shortening its service life. For example, in the textile industry, carbon fiber rubber rollers are used in spinning machines, looms, etc. If the deflection of the roller body is too large, it will cause serious wear on the roller surface, shortening the service life and increasing maintenance costs. Third, the deflection will cause additional vibration of the roller during rotation, increasing energy consumption. For example, in the food processing industry, carbon fiber rubber rollers are used in food conveyor lines, presses, etc. If the deflection of the roller body is too large, it will cause the roller vibration to intensify, increase energy consumption and reduce production efficiency. Fourth, if the deflection of the roller body is too large, it will cause additional vibration of the roller during rotation, which will be transmitted to the equipment and aggravate the vibration of the equipment. For example, in the printing industry, if the deflection of the carbon fiber rubber roller used in a high-speed printing machine is too large, it will cause the vibration of the printing machine to intensify, affecting the printing quality and shortening the service life of the equipment. Fifth, if the roller body deflection is too large, it will cause the roller to generate additional noise during rotation. For example, in the textile industry, if the deflection of the carbon fiber rubber roller used in the spinning machine is too large, it will cause the spinning machine to increase noise, affect the working environment, and cause harm to human health.

[0004] In addition, since the core material of the carbon fiber roller is CFRP (Carbon Fibre-reinforced Polymer), and CFRP is usually a thermosetting epoxy resin as a bonding material, after long-term aging, the CFRP pipe becomes fragile. When the roller core is re-coated with rubber, it needs to be sent to a vulcanization tank for high-temperature vulcanization, usually at a temperature of 150-200 degrees. Under the action of high temperature and rubber vulcanization pressure, the CFRP roller core will be damaged in most cases, and the roller core is easy to deform. In severe cases, the CFRP pipe will collapse. Utility Model Content

[0027] Specifically, two chambers are provided in the inner wall of the roller body 1 through a partition 7, and airbags 4 are respectively provided therein. The inflation pressures of the two airbags 4 can be adjusted respectively, so that the airbags 4 can support the roller body 1 more flexibly.

[0028] Example 3

[0029] This embodiment is an example of product parameters of the structure of embodiment 1 or embodiment 2.

[0031] The ratio of the roller core length to the diameter of the carbon fiber rubber roller in this embodiment is 20:1, the roller sleeve thickness is 20% of the roller core diameter, and the Shore A hardness of the roller sleeve is 65-70. The carbon fiber rubber roller has small deflection, high processing accuracy, long service life, low energy consumption, small equipment vibration, and low noise.

[0032] Example 4

[0033] This embodiment is an example of product parameters of the structure of embodiment 1 or embodiment 2.

[0034] The roller core 11 is 1500 mm long and 150 mm in diameter, made of T800 carbon fiber, the airbag 4 is made of polyurethane, and the inflation pressure is 0.8 MPa. The roller sleeve 12 is 30 mm thick and made of rubber, with a Shore A hardness of 90.

[0035] The ratio of the roller core length to the diameter of the carbon fiber rubber roller in this embodiment is 10:1, the roller sleeve thickness is 20% of the roller core diameter, and the Shore A hardness of the roller sleeve is 90. The carbon fiber rubber roller has small deflection, high processing accuracy, long service life, low energy consumption, small equipment vibration, and low noise.

[0036] Furthermore, the airbag 4 is cylindrical after being inflated.

[0039] In addition, since the roller core 11 is made of carbon fiber material, specifically CFRP (Carbon Fibre-reinforced Polymer), and CFRP is usually a thermosetting epoxy resin as a bonding material, after long-term aging, the CFRP pipe becomes fragile. When the roller core 11 is re-coated with rubber, it needs to be sent to a vulcanization tank for high-temperature vulcanization, usually at a temperature of 150-200 degrees. Under the action of high temperature and rubber vulcanization pressure, the CFRP roller core 11 will be damaged in most cases, and the roller core 11 is easy to deform.
