Description

Sanding belt for woodworking sanding machine

technical field

The utility model relates to the technical field of grinding and sanding belts, in particular to a sanding belt for woodworking sanding machines.

Background technique

The sanding belt is a kind of material for grinding, which is used to grind the surface of metal, wood and other objects to make it smooth and smooth. The structure of the sanding belt and the quality of the grinding process directly determine the grinding effect of the sanding belt. quality of the final product. Wood is easier to process and form than metal, but the surface quality of formed wood is more difficult to control than metal. For example, when planing or milling wood, it is easy to cause advanced splitting, stubble, burrs, etc. After the wood is processed and formed, it needs Sanding belts are further used for grinding and polishing, but the development of grinding technology at this stage is not optimistic, mainly because of insufficient innovative research and development of wood sanding belts. In addition, the sanding belt has been running at high speed during the process of sanding wood. Due to the high tension of the sanding belt, the sanding belt and the driving wheel will generate a certain temperature. Under the influence of this temperature, the sanding belt will last for a long time Operation, the sanding belt will have the problem of rapid aging, and even the sanding belt will break.

Utility model content

In order to overcome the problems in the prior art that the sanding belt for woodworking sanding machines is easy to break and the sanding effect is not good, the utility model proposes a sanding belt for woodworking sanding machines.

The technical scheme adopted by the utility model to solve the technical problems is specifically: a sanding belt for a woodworking sander, comprising a magnetic rubber layer, a base layer, a strengthening layer, an adhesive layer, an abrasive layer, and an anti-wear layer. The above-mentioned magnetic rubber layer is arranged under the base layer, and the reinforcement layer is arranged between the base layer and the bonding layer, and an isolation layer is also provided between the reinforcement layer and the bonding layer, and the abrasive layer passes through the bonding layer and the isolation layer. Fixed and bonded together, the coarse abrasive grains, medium abrasive grains and fine abrasive grains are evenly distributed in the abrasive layer in the shape of oblique bands, placed on the bonding layer, and the anti-wear layer is sprayed on the surface of the sanding belt, which is wear-resistant and aging-resistant role.

In the aforementioned sanding belt for a woodworking sander, the magnetic rubber layer is attached to the base layer by any one of hot pressing, ultrasonic waves, and bonding.

In the aforementioned sanding belt for woodworking sanding machines, the isolation layer is made of polyurethane or tough fiber materials.

In the aforementioned sanding belt for a woodworking sander, the strengthening layer and the isolation layer both have a mesh cross structure, and there is a cross connection between the reinforcement layer and the isolation layer.

In the aforementioned sanding belt for a woodworking sander, the oblique belt-shaped coarse abrasive grain layer, medium abrasive grain layer, and fine abrasive grain layer are arranged circularly in sequence to form an abrasive material layer.

In the aforementioned sanding belt for a woodworking sanding machine, the inclination angle A formed between the oblique belt-shaped abrasive grain layer and the horizontal line is 20° to 70°.

The beneficial effect of the utility model is that the utility model is a sanding belt for a woodworking sanding machine. The magnetic rubber layer is arranged under the base layer, and the rubber layer has high toughness and impact resistance. The force of the belt provides a buffer, and on the other hand, it can effectively avoid the sanding belt from breaking; the mesh reinforcement layer is arranged between the base layer and the bonding layer, and there is also The mesh isolation layer, the double-layer arrangement of the isolation layer and the reinforcement layer greatly improves the overall toughness, impact resistance and wear resistance of the sanding belt; the oblique belt-shaped abrasive layer improves the grinding effect and processing efficiency of the sanding belt.
