Apron feeder is a continuous transport machine widely used in mining, metallurgy, building materials, ports, coal and chemical industry and mining enterprises. It is mainly used for continuously and uniformly supplying and transporting all kinds of bulk heavy and abrasive bulk materials to the crusher, batching device or transportation equipment from the storage bin or transfer funnel. It is one of the important and essential equipment’s in the process of ore and raw material treatment and continuous production
In the process of apron feeder used will appear all sorts of problems, such as chain skid, wandering, size, etc., we are Henan Excellent Machinery Co., Ltd production of plate type feeder adopts advanced tooling technology, we have the big tonnage press, making a molding p plate, we have a professional chain of die cutting machine and advanced laser cutting machine, can effectively guarantee the accuracy of the chain. We adopt automatic welding robot with cash to ensure smooth welding and beautiful appearance. We use advanced shot blasting machine, sand blasting process to ensure that our product film thickness meet customer requirements. There are two reasons for the directness of deviation:
First, the driving forces on both sides are unbalanced, which leads to the inconsistent situation of the chain plate in the driving process;
Second, the lateral force of the roller on the chain plate causes the chain plate to deviate from the straight line.
The following is an analysis of the specific reasons
(1) Errors occur in the installation and debugging of the chain and sprocket of apron feeder. If the chain tensioning device is not installed and adjusted properly, the tension bow | force on both sides of the chain plate is not coordinated. Therefore, off-track occurs during operation, which is the most common reason for off-track. This time to adjust the rear tensioning device to correct this phenomenon - a boat appeared in the new installation and replacement of the chain plate equipment during the trial.
(2) Uneven material blanking during chain plate transportation. IN the apron feeder normal no-load operation when the situation is normal, and in the load transport deviation, this should be from the situation of the material to launch an investigation, because in the apron feeder in the process of operation of this situation is very common. The solution is to ensure the materials first
Material point in the feeder chain plate full width direction, in addition to the material blanking mouth generally should not exceed two thirds of the chain plate width.
(3) The quality of the chain plate itself. The quality problem of the chain plate itself will also lead to the imbalance of the tension on both sides of the belt, such as: the chain plate itself is not straight, the width on both sides of the chain plate is not the same, so the chain plate will run to a large tensioning tension. This kind of deviation phenomenon is mainly caused by the quality of the chain plate itself. For the first time, we want to purchase the original factory accessories to ensure the quality. Secondly, if the problem is not serious, you can adjust the tensioning wire to correct the chain plate error. If it still deviates, the chain plate with qualified quality shall be replaced and adjusted again. (4) The chain plate is deformed. Chain plate is a kind of material with elastic characteristics, so after a period of use will appear permanent deformation, and then will make its relaxation and tension drop, thus causing deflection. IN this case, adjust the tensioning device to eliminate the chain slack. If it cannot be solved, a new chain plate should be replaced.
(5) Determine sprocket wheel or redirected sprocket wheel pollution. There are often some sticky materials in the materials transported by the chain plate, which sometimes stick to the sprocket.
This changes the diameter of the sprocket or the coefficient of friction. At this time the tension of the chain plate will appear uneven, resulting in the chain plate deviation. This phenomenon should regularly clean the sprocket of the bonding material.
In addition, it can solve all the problems of apron feeder chains perfectly. Besides, I want to know more products, such as belt conveyor, bucket elevator, feeder, seminal chain, screw, vibrating screen. You can visit our website at www.exctmach.com.
