Description of the figures the symbols:

1. a composite roller body; 1-1, carbon fiber cloth; 1-2, glass fiber tubes; 2. a shaft head; 2-1, a shaft core; 2-2, stainless steel shaft tube; 2-3, a ceramic shaft sleeve; 2-4, connecting a disc; 3. countersunk head screw.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples, so that those skilled in the art can easily implement the present invention.

Example (b):

as shown in fig. 1, the utility model is provided with a composite roller body 1, a shaft head 2 and a countersunk screw 3; the composite roller body 1 is composed of a glass fiber tube 1-2 with an inner layer playing a role of supporting a framework and carbon fiber cloth 1-1 with an outer layer playing a role of corrosion resistance and wear resistance, the glass fiber tube 1-2 is formed by winding and solidifying the glass fiber tube 1-2 through equipment such as a mold core, the carbon fiber cloth 1-1 takes the glass fiber tube 1-2 as the framework, the glass fiber tube is tightly wound on the glass fiber tube framework in a gum dipping winding mode, and the composite roller body 1 is formed after solidification.

The shaft core 2-1 and the stainless steel shaft tube 2-2 are welded through the connecting discs 2-4, the connecting discs 2-4 are divided into an inner part and an outer part, the inner connecting discs and the outer connecting discs keep a certain distance, and the inner connecting discs and the outer connecting discs are respectively fixed at two ends of the shaft tube, so that the radial stress of the shaft core is more uniform, and the weight of the shaft head is reduced; after turning the stainless steel shaft tube 2-2, performing interference fit with an inner hole of the composite roller body 1 to perform assembly with glue; after assembly, countersunk screws 3 are uniformly distributed on the circumference of the connecting disc 2-4, the countersunk screws 3 need to penetrate through the composite roller body 1 and the stainless steel shaft tube 2-2 and extend into the connecting disc 2-4 for locking, and the epoxy resin adhesive is used for filling and repairing the countersunk screws 3 or the positioning pin holes to the excircle of the composite roller body 1; after the spindle head 2 and the composite roller body 1 are subjected to finish machining, the ceramic shaft sleeve 2-3 and the spindle core 2-1 are firmly bonded through a binder, the ceramic shaft sleeve can effectively improve the sealing property, and the wear resistance, acid resistance, alkali resistance and other properties of the ceramic shaft sleeve are obviously higher than those of a metal spindle core.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention, as various modifications and variations will be apparent to those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the scope defined by the claims of the present invention shall be within the protection scope of the present invention.
