Description

Technical Field

[0001] The present application relates to the technical field of steel rollers, and in particular to a high-strength carbon fiber roller. Background Art

[0002] On some plastic film production equipment, rollers are needed to transport, wind and press the film. Hollow steel rollers or carbon fiber rollers are used. In order to reduce the possibility of deformation of the steel rollers or carbon fiber rollers during long-term use, there are usually certain requirements for their thickness, which also makes the steel rollers or carbon fiber rollers have a large weight.

[0003] In the prior art, steel rollers and carbon fiber materials are usually combined, and a carbon fiber layer is set inside the steel roller. The carbon fiber has a lighter weight and better strength, making the steel roller equipped with carbon fiber lighter and more resistant to bending than ordinary steel rollers.

[0004] Although the combination of the two increases the overall strength to a certain extent, in actual practice, the steel roller itself is heavy, and the two ends of the steel roller are rotatably connected to the machine body. The position of the steel roller away from the two ends lacks support, resulting in relatively weak strength in the middle position. This will cause the steel roller to undergo certain deformation during long-term use, shortening its service life. Utility Model Content

[0005] In order to reduce the possibility of deformation of the steel roller and increase the service life of the steel roller, the present application provides a high-strength carbon fiber roller.

[0006] The high-strength carbon fiber roller provided in this application adopts the following technical solution:

[0007] A high-strength carbon fiber roller comprises a carbon fiber roller body with a hollow interior, wherein two ends of the carbon fiber roller body are connected to connecting shafts rotatably connected to a machine body, a plurality of reinforcing ribs are fixed in the carbon fiber roller body for reinforcement, the length direction of the reinforcing ribs is consistent with the length direction of the carbon fiber roller body, the plurality of reinforcing ribs are evenly distributed along the circumference of the axis of the carbon fiber roller body, and a plurality of supporting devices for supporting are arranged in the carbon fiber roller body.

[0008] By adopting the above technical solution, the reinforcement ribs are provided to increase the overall strength of the carbon fiber roller body, while the support device is provided to further increase the internal and overall strength of the carbon fiber roller body, thereby increasing the service life of the carbon fiber roller and reducing the possibility of damage thereof.

[0009] Optionally, the support device comprises a support ring coaxial with the carbon fiber roller body, the support ring is provided with a plurality of support rods extending in its radial direction, and the ends of the support rods are fixed with support blocks abutting against the inner wall of the carbon fiber roller body.

[0010] By adopting the above technical solution, the support rod cooperates with the support ring so that the support block is pressed against the inner wall of the carbon fiber roller body, thereby enhancing the overall strength.

[0011] Optionally, the support rod is slidably connected to the support ring, the support rod slides radially along the support ring, the support rod is provided with a support spring for pushing the support block against the inner wall of the carbon fiber roller body, and the support ring is provided with a driving component for driving the support rod to move and make the support block press against the inner wall of the carbon fiber roller body.

[0012] By adopting the above technical solution, the support rod is slidably connected to the support ring, which makes it easy to install the support device as a whole into the carbon fiber roller body, and also makes it easy to remove the support device from the carbon fiber roller body. The staff can act on the drive assembly to make the support block press against the inner wall of the carbon fiber roller body, thereby realizing the installation of the support device.

[0013] Optionally, connecting disks for closing the carbon fiber roller body are fixed at both ends of the carbon fiber roller body, and the connecting shaft is fixed on the connecting disks.

[0014] By adopting the above technical solution, the setting of the connecting plate facilitates the installation of the connecting shaft on the one hand, and facilitates the internal maintenance and the installation and disassembly of the supporting device on the other hand.

[0015] Optionally, positioning grooves are formed at both ends of the carbon fiber roller, the connecting plate is located in the positioning grooves, and the connecting plate is fixed in the positioning grooves by bolts.

[0016] By adopting the above technical solution, the setting of the positioning groove facilitates the installation and positioning of the connecting disk and also plays a limiting role for the connecting disk.

[0017] Optionally, the connecting shaft is a hollow cylindrical tube, and the driving assembly includes a driving shaft passing through a plurality of supporting rings and the connecting shaft, and the driving shaft is coaxially provided with a plurality of driving blocks corresponding to the supporting rings, and the driving blocks are in the shape of a truncated cone, and when the driving shaft moves along its axial direction, the driving blocks push the supporting rods to move and make the supporting blocks press against the inner wall of the carbon fiber roller.

[0018] By adopting the above technical solution, the staff can rotate the driving shaft so that the driving shaft drives the driving block to move along its axial direction. Under the action of the support spring, the support block is pressed against the inner wall of the carbon fiber roller body, reducing the possibility of the support ring moving along its axial direction. The support rod slides on the surface of the driving block. Since the driving block is in the shape of a truncated cone, the support rod drives the support block to move radially along the carbon fiber roller body, which makes it easier for the support block to press against or separate from the inner wall of the carbon fiber roller body.

[0019] Optionally, the driving shaft is threadedly connected to the connecting shaft, and a driving groove is provided at the end of the driving shaft to facilitate the rotation of the driving shaft relative to the connecting shaft.

[0022] The reinforcing ribs are used to increase the overall strength inside the carbon fiber roller body;

[0023] According to the actual performance of the carbon fiber roller during work, the staff can install support devices at different positions on the carbon fiber roller to increase the strength of the corresponding positions. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following is combined with Figure 1-2 This application is described in further detail.

A plurality of connecting bolts are passed through the connecting plate 3, and the connecting bolts are threadedly connected to the end surface of the carbon fiber roller body 1, thereby fixing the connecting plate 3 on the carbon fiber roller body 1.

[0033] Reference Figure 1 , a support spring is sleeved on the support rod 7, and the support spring pushes the support block 8 to press against the inner wall of the carbon fiber roller body 1.
