technical field

The utility model relates to the technical field of feeder equipment, in particular to a belt conveying weighing feeder.

Background technique

The main purpose of the belt weighing machine is that the belt is continuously conveying materials, adding a load cell, and combining with the belt speed, the weight of the belt can be calculated. The traditional belt weighing machine is to add a load cell at both ends of a certain idler, and then combine the belt speed to calculate the weight of the conveyed material. Since only two sensors can be installed on one idler and the weighing weight is limited, the calculated weight of the conveyed material has a large error. After searching, the Chinese patent with the authorization announcement number CN206074100U discloses a belt weighing machine in the technical field of material conveying and weighing equipment, including a frame and brackets symmetrically arranged on the left and right sides of the bottom of the frame. The bottom of the bracket is provided with a load sensor, the right side of the rack is provided with a motor support, a motor is provided between the two sets of the fixing plates, the power output end of the motor is connected with a driving roller, the driving roller The outer wall of the wheel is connected with a conveyor belt, the top of the motor support is provided with a feeder, the bottom of the idler fixing rod is connected with an idler, and a driven roller is installed on the driven roller seat, so The bottom of the right side of the junction box is connected with a tensioning roller fixing seat by bolts, the inner cavity bottom of the tensioning roller fixing seat is provided with a tensioning roller, and the left side of the tensioning roller fixing seat is connected with a deviation correction idler, The utility model has the advantages of simple structure, convenient use, large weighing weight, and high accuracy of the calculated weight of the transported material.

In the above design, the tensioning force of the conveyor belt is controlled by the tensioning roller. The traditional tensioning roller stretches the chute with seat bearing by extending the screw. Because of the long adjustment stroke, the screw has a long part sticking out of the outside of the equipment. At the same time, the space for replacing the belt is restricted. Secondly, the screw is exposed to the outside and is easily polluted by dust or other impurities, which leads to difficulty in adjustment. Therefore, we propose a belt conveyor weighing feeder to solve the above problems. .
