In order to ensure the service life of the interface during the belt operation, the mouth can be raised according to the direction of the belt operation.

Therefore, the chain conveyor is a key technology in the bonding process and must be operated by experienced personnel or directed on site. After tearing the grinding step of the joint, the initial joint is performed, and the mismatched parts are corrected, and then the joint is polished. The purpose of polishing is to remove the rubber adhering to the cloth layer, while grinding the cloth layer to achieve the effect of increasing the roughness of the cloth layer, increasing the bonding area and improving the bonding strength. Practice has proved that under certain conditions, the bonding strength will increase with the increase of roughness.

Also, before bonding, keep the bonding surface clean to prevent contamination. The relationship between the thickness of the adhesive layer and the shear strength. Because the thin coating is less prone to flow and creep, there is little possibility of bubbles and defects, and there is less internal stress at the interface. Therefore, it is beneficial to improve the adhesion of the interface. However, when the adhesive layer is too thin, it is easy to form insufficient glue and the coating is discontinuous, which will also reduce the bonding strength. Therefore, when the adhesive is applied, the thickness of the coating should be as thin as possible without a lack of glue.

The timing of the combination determines when the two parts of the interface overlap, which will directly affect the combination effect. Upon request, the adhesive can be ground without sticking to the hand only after application. Too early or too late can also reduce the bonding quality. When the lap operation is accurate and the lap joint is lap, the center line at both ends of the belt must be in the same straight line, and the steps should be well matched to avoid repeated stripping and adhesion due to misalignment. After lapping the joint, use the hammer to start at the center line and tap the sides in turn. Try to clamp the joint surface with two flat steel plates, and fix it with bolts, and then release it after the adhesive curing, so that the bonding effect is better.
