The vulcanizing machine is generally consists of four parts:
1) clamping mechanism
clamping mechanism are generally composed of the frame and bolts.
2) control systems
The control system is composed of an electric control box and primary & secondary wire cables.
3) pressure system
The pressure system is composed of a water pressure plate and a pressure test pump.
4) heating system
The heating system is composed of heating plates and heat insulation plates.
When customers purchase belt vulcanizers, they generally need to confirm three questions, one is the width of the belt; the other is the width of the belt to be jointed; the third is whether the vulcanizer is explosion-proof or not.
Our company's conveyor belt vulcanizing machine has the characteristics of high strength and not easy to be deformed. The equipment is widely used, and can be applied to the hot joints of metallurgical, chemical, metal mines, power plants, ports, docks and other on-site conveyors. The tensile strength is not less than 90% of the original belt, the joint is smooth, and the wear on the drum can be reduced, and the service life of the conveyor and the rubber belt can be prolonged.
Compared with similar products, Arphu brand conveyor belt vulcanizing machine adopts unique technology and unique technology of fully automatic precision digital display control system. The vulcanization temperature is uniform and precise, and the vulcanization pressure is uniform. The whole machine is light in weight, lighter than similar models, high in strength, and ultra-high pressure is not easily deformed. Reliable and durable.
The first factor affecting the vulcanization process of the belt vulcanizer: vulcanization temperature
The vulcanization temperature determines the degree of vulcanization uniformity. Experience and tests have shown that when the temperature is 10 °C higher, the vulcanization time is shortened by about half, and the rubber is a poor thermal conductor. The vulcanization process of the product will vary depending on the temperature of the product. If the uniform vulcanization effect is achieved, the temperature control of thick rubber products is very critical, and the temperature should be gradually increased. The principle is low temperature vulcanization for a long time. Arphu conveyor belt vulcanizing machine heating plate not only has good power saving effect, but also has automatic temperature control system to effectively improve the vulcanization quality of the product.
The second factor affecting the vulcanization process of the belt vulcanizer: the amount of sulfur
The higher the amount of sulfur in the belt vulcanizer heating plate, the faster the vulcanization rate will be, and the higher the vulcanization procedure will be. However, the solubility in sulfur and rubber is limited, and the sulfur is used as much as possible. Sulfur will be precipitated from the surface of the rubber compound. This phenomenon is called “sulphur spraying”. To minimize the occurrence of sulfur injection, the method is to add an appropriate amount of sulfur at the lowest possible temperature. In general, sulfur is soft rubber. The dosage should not exceed 3%, the semi-hard rubber should not exceed 20%, and the pure hard rubber should be used at a higher level, up to 40%.
The third factor affecting the vulcanization process of the belt vulcanizer: vulcanization time
Vulcanization time is an important link in the vulcanization process. If it is too short or the vulcanization process is not enough, it is commonly called “under-sulfur: if it is too long, the vulcanization degree will be too high, commonly known as “persulfurization”, only the appropriate length of time can be achieved. The best vulcanization effect, commonly known as positive vulcanization.
1. The construction site should be equipped with 2 sets of 7Kg dry powder fire extinguishers, sandboxes and water.
2. All kinds of electrical equipment must have reliable grounding protection, the cable must be inspected intact.
3. Gasoline, conveyor belt and other flammable materials should be placed away from the fire source and have someone to look after.
4. The vulcanization process must be attended by a special person. After the end of vulcanization, the power supply must be cut off, the work place should be cleaned, and the vulcanizer and various tools should be sorted and recycled.
1. The user must determine which type of vulcanizer to choose according to the environment in which the vulcanizer is used.
2. Determine the belt width parameters of the vulcanizer according to the width of the conveyor belt.
3. Determine the operating voltage parameters of the vulcanizer according to the power supply conditions in the use environment.
4. Determine the splice length parameters of the vulcanizer according to the strength of the conveyor belt or the length of the conveyor joint required by the user.
5. Determine the bias angle parameters of the vulcanizer according to the user's own experience, tradition, habits and requirements.
6. Determine the working pressure parameters of the vulcanizer according to the bonding technology and process requirements.
