Belt conveyor manufacturer directly supplies conveying equipment. Circular belt conveyor lines and circular belt assembly lines for express delivery and warehousing.

Classification of Common Production Lines

Slat Chain Assembly Line Features: Capable of carrying heavy products and running synchronously with the production line; supports product climbing. It does not operate at a fast production pace. With chain plates as the carrier, it realizes stable product transportation.

Roller Conveyor Line Features: Suitable for a wide range of product types with few restrictions. Used together with stoppers, it enables continuous, paced operation and product accumulation. Equipped with lifting and translating devices, it allows offline maintenance or inspection of products without interrupting the operation of the whole line.

Belt Conveyor Line Features: Designed for light-weight products with few shape restrictions. It runs synchronously with the production line and can realize product climbing and turning. Using belts as the carrier, it delivers smooth transportation with low noise. It supports long-distance conveying of light materials or products.

Conveyor Line Operation Instructions

1. Brief Electrical Operation The production line requires a three-phase four-wire power supply, fitted with a main external switch. (A 4-pole three-phase four-wire switch can be used; alternatively, the switch may only control the three-phase power while the neutral wire is directly connected. Warning: Do not route the neutral wire of the second wiring method through another separate switch.) In the electric control box: Terminal N connects to the neutral wire; Terminals A, B, C connect to the three-phase power supply; Terminals U, V, W connect to the motor. Terminals 3 and 4 connect to F1, F2 of the variable speed motor. Terminals 5, 6, 7 connect to u, v, w of the variable speed motor.
2. Motor Start-up Procedure Switch on the power first. All three power indicator lights will turn on, which confirms three-phase power has reached the control box. Press the blue motor start button to activate the motor. If the motor fails to start, open the control box door and check the second DZ108 circuit breaker on the first row. Confirm if the red lever is up and blue lever is down. If not, press down the blue lever. After the motor starts, turn on the speed controller switch. Slowly turn up the potentiometer of the speed controller until the tachometer shows your target speed. For shutdown: Slowly turn the potentiometer down to zero, switch off the speed controller, press the red motor stop button, then cut off the main power switch.
3. Fluorescent Lamp Control Press the blue lighting button to turn on fluorescent lamps; press the red lighting button to turn them off. If the lamps fail to light up, check if the flat switch on the lamp bracket is at position 1. Then check whether the 3rd and 4th DZ47 breakers on the first row are switched on.

Maintenance of Conveyor Line Components

1. Maintenance for Head Motor Never allow water into the motor. Do not apply diesel oil or liquid organic compounds to the motor, as these can damage insulation and cause breakdowns. The speed governor maintenance rules are the same as for the motor. For other requirements, refer to motor maintenance specifications in electrician handbooks.
2. Chain Maintenance After long running hours, lubricant on chains may evaporate due to heat, resulting in unstable running, increased noise and creeping. Open the tail sealing plate and apply grease or heavy lubricating oil to the chain.
3. Maintenance for Conveyor Head Reducer Drain all old oil, clean the reducer interior with diesel or gasoline and drain fully. Refill new lubricant to the middle level of the sight glass. Check monthly for low oil level. Replace lubricant once every year afterwards. Too much lubricant may overheat the reducer, overload the motor and trigger the motor protection switch. Insufficient lubricant will cause reducer overheating, excessive noise and seizure leading to permanent damage.
