Conveyor Belt vulcanizer is generally composed of four parts

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.

Three factors to be paid attention to during vulcanization of belt vulcanizer

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.

4 common safety measures for conveyor belt vulcanizers

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.

6 Tips on how to choose a good conveyor belt vulcanizer

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.

Maintenance and servicing of Conveyor Belt Vulcanizer

Conveyor belt vulcanizer, as repair and splicing tools, maintenance and servicing of conveyor belt vulcanizer is very important, it can prolong service life.
As maintenance of belt vulcanizing press, please pay more attention to the following questions:
(1)Storage in dry and draughty environment to avoid of shortage of electrical resistor due to moisture.
(2)Don't operate belt vulcanizing press in raining weather outside.
(3)If work in moist field, please put sleepers under machine to avoid laying it on the ground directly, which is prohibited.
(4)If there is water in heating plates, please open cover and pipe water out, then set to "MANUAL OPERATION" on the control cabinet and heat up to 100℃, keep about 30 minutes, after emergent usage of heating plates, please contact after sale service and consider change electrical resistors
(5)If long time no use belt vulcanizing press, please connect power to heat heating plate each 15 days (set temperature 100℃) and keep 30 minutes.
(6)After vulcanizing job, please pipe out water from water plate completely, especially in winter.

Common Splicing and Repairing Methods by Conveyor Belt Vulcanizing Press

There are three common methods for splicing and repairing conveyor belt:
(1)Hot vulcanizing splicing method: mainly choose proper belt vulcanizing press, repair vulcanizing press and hot vulcanization material, it's the most reliable and best splicing method;
(2)Cold splicing method: use cold adhesive agent and special tools;
(3)Mechanical repair method: mainly use fastener, bolts or soft metal wire to repair or connect damaged part.
For the mentioned three methods, the best method of repair and splicing conveyor belt is hot vulcanizing splicing. Its advantages are long life service, almost completely the same as original conveyor belt after repair and splicing, suitable heavy materials, long distance and high speed transportation.

Analysis and Treatment of Conveyor Belt Vulcanizer for Common Questions

Conveyor belt vulcanizer (also called conveyor belt vulcanizing press), as for splicing tools for conveyor belt, in the process of using it may have some small problems, mostly due to improper operation, storage or maintenance.
FAQ 01: If heating up time is too long or can't reach 145°C:
(1) If install heat insulation plate between cross beams and heating plates, if not, please install it and re-test it.
(2) If temperature can't reach set temperature, please check if switch of "vulcanizing time" open or not, if opened, belt vulcanizer is in heat preservation stage, and temperature can't rise. Then please close the switch.
(3) If doesn't work after test the first two steps, please check if the heat insulation plates are moist, if yes, please drying them by heating plates.
(4) If it doesn't work after the first three steps, please contact after sale service.
FAQ 02: If temperature non-uniformity lead to bad splicing:
(1) Check if heat insulation plates damaged;
(2)If heat insulation plates work well, please heat up heating plates separately and test heating plates surface by thermometric indicator. If temperature is non-uniformity, maybe heat resistance is damaged.
FAQ 03: If pressure can't reach to set value by pump:
(1) If inlet of water plate is blocked by too tighten of bolts and nuts, if yes, please loosen bolts and nuts;
(2)If leakage of water or air and tighten relevant bolts, and check seals of pump.
FAQ 04: If adhesive between belt and heating plates
Please check if use heat-resistant paper between conveyor belt and heating plates.
FAQ 05: Leakage of water plate
(1)Check the leakage point, if leakage from edges of water plate, please tighten bolts;
(2)If leakage from water plate surface, please change belt of water plate.,
