To ensure that the joint quality of the conveyor belt joint machine meets the standards, the following aspects can be taken into account:
**1, Equipment related**
1. * * Equipment selection and maintenance**
-Choose a joint machine that is suitable for the type of conveyor belt (such as rubber belt, chain conveyor belt, etc.), width, and working environment (temperature, humidity, etc.). For example, for heavy-duty rubber conveyor belts, a vulcanization joint machine with appropriate power and pressure should be selected.
-Regularly maintain the equipment, check whether the heating device is working properly (for hot vulcanization joint machines), whether the pressure system is stable, and whether the electrodes of the welding equipment are worn (for welding joint machines).
2. * * Accurate parameter settings**
-Accurately set the various parameters of the joint machine based on the material, thickness, and other parameters of the conveyor belt. The temperature, pressure, and time during hot vulcanization. The temperature setting for the general rubber conveyor belt hot vulcanization joint is around 140-150 ℃, the pressure is 0.5-1MPa, and the time varies from 10-30 minutes depending on the joint size.

**2, Operation process**
1. * * Joint preparation**
-Ensure that both ends of the conveyor belt are cut neatly, with smooth edges and no defects such as burrs or cracks. For multi-layer conveyor belts, it is necessary to ensure that each layer is aligned.
-Clean the joint area and remove impurities such as oil and dust to avoid affecting the quality of the joint. For example, when cold bonding joints, the cleaned joint area should be wiped with a clean cloth.
2. * * Operating standards**
-Operators need to undergo professional training and be familiar with the operation process of the joint machine. During the operation, strictly follow the operation manual. For example, when performing hot vulcanization joints, accurately place the vulcanization plate to ensure even pressure distribution.
-For welded joints, it is necessary to control parameters such as welding speed and current to ensure welding quality. During the welding process, it is necessary to avoid situations such as virtual welding and leakage welding.

**3, Quality inspection**
1. * * Appearance inspection**
-After the joint is completed, the first step is to conduct a visual inspection. The surface of the joint should be flat and smooth, without obvious defects such as protrusions, depressions, or cracks.
-For joints covered with vulcanized rubber, check the appearance quality of the vulcanized rubber, such as uniform color and no bubbles.
2. * * Strength testing**
-Use tensile testing machines and other equipment to test the strength of conveyor belt joints. The tensile strength of the joint should reach a certain proportion of the strength of the conveyor belt body (generally not less than 80% -90%).
-Before practical application, small batch sampling tests can be conducted to ensure that the joint quality meets the requirements before large-scale use.
