Pipeline conveyor belt analysis of several types of conveyor belt joint method of roller conveyor; the role of redirection drum in belt conveyor; usually pay attention to the maintenance of roller conveyor of belt conveyor, several types of conveyor belt joint method:
The hot vulcanized joint has proved to be the most ideal joint method, which can ensure high joint efficiency, and is also very messy. The joint life is also long and easy to grasp. This joint method is more efficient and mechanical than the mechanical joint, and should be able to have a better joint effect, but from a practical point of view, because the process premise is difficult to grasp, the quality of the adhesive has a great influence on the joint. So it is not very messy. However, in order to ensure the joint effect, the conveyor belt of grade 8 or higher is generally a method of using a hot vulcanized joint. The cold bonding head, that is, the cold bonding adhesive is used for the joint. 2. Joint method of PVC and PVG whole core flame-retardant conveyor belt: Because the structure of the whole core belt is special, the joint is not easy, so most of them adopt the mechanical joint method, that is, the belt buckle joint. The structure of the joint is a finger joint. The hot vulcanization joint process of PVC and PVG whole core flame retardant conveyor belt is more complicated, and the requirements for equipment are relatively high. However, there are disadvantages such as troublesome process, high cost, and long joint time. In the PVC and PVG whole core flame retardant antistatic conveyor belt joints, the product is generally used in products with 8 or less belts. 1. Joint method of ordinary conveyor belt: Mechanical joint generally refers to the use of belt buckle joint. This joint method is convenient and economical, but the joint has low efficiency and easy damage, which has certain influence on the service life of conveyor belt products. 3. Joint method of layered conveyor belt. The joint method between different conveyor belts is different, mainly introducing several common types of joint methods.
Analysis of the role of the reversing drum in the belt conveyor. In the belt conveyor, the direction of the conveyor belt can be changed or the belt tension can be increased by reversing the drum. The wrap angle of the conveyor belt and the drive drum can also be increased. .
The adjustment of the belt conveyor driving drum and the reversing drum is an important part of the belt deviation adjustment. Since a belt conveyor has at least 2 to 5 rollers, all drums must be installed at a position perpendicular to the centerline of the belt conveyor. If the deflection is too large, deviation will occur. It is similar to the adjustment roller set. For the head roller, such as the belt, to the right side of the drum, the bearing housing on the right side should move forward, and the belt should be moved to the left side of the drum. The bearing housing on the left side should move forward, and the corresponding bearing can also Move the left bearing housing back or the right bearing housing back. The tail roller is adjusted in the opposite way to the head roller.
The main reasons for the failure of the drum brake are:
(1) Whether the air pressure is abnormal, such as whether the air pump is abnormal, whether the air pipe is leaking or blocked.
(2) Whether the brake pads are damaged.
(3) Whether the brake discs on both sides of the drum are missing.
(4) Whether the brake system is operated or not, so that the brake command is not transmitted smoothly.
(51) Whether the power transmission system cuts off the power in time.
(6) For belt friction brakes, check whether the friction belt is loose or the friction factor is reduced and should be adjusted or replaced.
Adjustment of the tension: The adjustment of the belt tension is a very important part of the belt conveyor's deviation adjustment. The upper redirection drum of the heavy hammer should be perpendicular to the vertical line of gravity except for the longitudinal direction of the belt, that is, the horizontal line of the shaft should be ensured. When tensioning with a screw or hydraulic cylinder, the two housings of the tensioning drum should be translated simultaneously to ensure that the drum axis is perpendicular to the longitudinal direction of the belt. The specific method of adjusting the belt deviation is similar to the adjustment at the drum.
Pay more attention to the maintenance of the belt conveyor
Start and stop conveyors should normally be started under no-load conditions. When several belt conveyors are installed in sequence, a lockable starter should be used to start and stop in a certain sequence through the control room. In addition, in order to prevent accidents, each conveyor should also be set to start or stop the button on the ground, you can stop any one. In order to prevent the conveyor belt from being longitudinally torn for some reason, when the length of the conveyor exceeds 30 m, a stop button should be installed at a certain distance (such as 25-30 m) along the entire length of the conveyor.
In order to ensure reliable operation of the belt conveyor, the most important thing is to find and eliminate possible failures in time. To this end, the operator must observe the working condition of the transport machine at any time, and if it is found to be abnormal, it should be dealt with in time. It is important that mechanical workers regularly inspect and inspect any conditions or components that require attention. For example, a roller does not seem to be very important, but a high-speed conveyor belt that transports abrasive materials can quickly wear through its outer casing, creating a blade that can severely damage an expensive conveyor belt.
