Product Introduction

Conveyer belt vulcanization joint (patching) machine series products adopt combined type and electrical heating technique, small temperature difference of hot plate and evenly heating. New high-pressure water pockets are of pressure equalization, and convenient usage, and reliable quality. Control system adopts new automatic numerical control case. Electrical components adopt imported DELIXI electrical appliance, with simple operation, stable performance and light weight, applicable to vulcanization joint (patching) of various belts like canvas, nylon, steel wire core and PVC/PVG. In order to save working time, it's feasible to choose water cooling system for vulcanizing temperature falling to 60℃ only within 20 minutes, greatly improving working efficiency. The conveyer belt vulcanization joint (patching) machine is a kind of brand-new and ideal conveyer belt glue joint (patching) equipment, wildly used in various transportation belt vulcanization joints and restoration of these industries such as metallurgy, mine, cement, power plant, port, building materials and chemical.

ZLJ combined-type conveyer belt vulcanization joint machine’s 5 major innovative technologies:

1.Our company has developed the latest vulcanizing machine smart temperature control box, which adopts insulated, shock-resistant and water-proof design, able to perfectly achieve vulcanizing machine's automatic heating and heat preservation, with the function of automatic power off and warning after finishing work. Meanwhile, it allows for multi-channel temperature monitoring system, that is to say, it allows for real-time monitoring the temperature of heating plate's 3 to 5 different parts, and intuitively display the temperature difference of vulcanization joint, so as to ensure joint quality.

2.The new-style mute high-pressure hydraulic pump possesses the characteristics of small size, light weight, mass flow, low noise, fast response and strong impact resistance. Our company's high-pressure hydraulic pumps of the up-to-date style are of elegant appearance, smaller size and lighter weight, with the water injection rate being double times of the previous-generation products'. Equipped with high-pressure water pocket, it can achieve the pressure of 2.3Mpa, and perfectly achieve vulcanization joint's pressure requirements.

3.Our company developed rubber pressure water pocket in 2005, perfectly replacing old-fashioned vulcanizing machine hydraulic pressure plate. This revolutionary technology has thoroughly overturned various pressuring technologies of conveyer belt vulcanizing machine, and made our company's vulcanizing machine products improved to a higher level, possessing a leading advantage in the fierce market competition, comparable to and even transcend the imported products from Canada and Germany. Since then, it has played a leading role in the industry of ZLJ combined-type conveyer belt vulcanization joint machine.

4.Our company developed integrated plates of silica gel heating element, with the same size of heating plate, without splicing, ensuring the maximum heating area, even temperature and fast heating. It’s feasible to bear the highest temperature of 180℃, and as such, the innovative heating technology of vulcanizing machine has now become the most ideal heating element of vulcanizing machine, maintaining our company’s leading role in the industrial technologies.

It's feasible to customize different types of connectors according to customers' requirements.
