Description

Material dumping and rolling prevention device and method for feeding machine Technical Field The application relates to the technical field of tobacco production equipment, in particular to a device and a method for preventing materials from toppling and rolling of a feeder. Background The feeder is a common conveying device in the industries of tobacco, food, chemical industry and the like and is used for uniformly conveying materials to downstream equipment (such as a lifter, a vibrating conveyor and the like). Under the scene that the feeding machine and the lifting machine are matched for use, a certain height difference exists between the discharge end of the material conveying belt of the feeding machine and the feed inlet at the bottom of the lifting machine. In the process that the material falls onto the elevator from the discharge end of the conveyer belt, the material is easy to fall down and roll due to the gravity effect and blanking impact. This problem of toppling and tumbling is particularly pronounced for flaky, fragile materials such as tobacco. The materials are out of control in the falling process, collide and squeeze each other, so that the breakage rate of tobacco leaves and cut tobacco is obviously increased, the utilization rate of raw materials is reduced, the production cost is increased, the processing quality of subsequent procedures is affected, and the quality of a final product is adversely affected. In the prior art, the above problems are generally attempted to be alleviated by adjusting the speed of a conveyor belt, but the problems of dumping, rolling and crushing of materials caused by the height difference of blanking cannot be effectively solved. Disclosure of Invention The application provides a device and a method for preventing materials from toppling and rolling of a feeder, and aims to solve the problems. In one aspect, there is provided a feeder anti-material dumping and tumbling device comprising: The connecting seat is positioned above the material conveying belt and comprises a connecting plate, a first connecting rod and a rotating rod, wherein the connecting plate is used for being fixedly connected with an external object, the first connecting rod is fixedly connected with the connecting plate, and the rotating rod is rotationally connected with the connecting plate; The material blocking rods are fixedly connected with the rotating rods, are distributed at intervals along the extending direction of the rotating rods, are positioned at the discharge ends of the material conveying belts, and are internally provided with coil springs, and under the condition that no material pushes the material blocking rods, the elastic force of the coil springs drives the rotating rods to rotate until the material blocking rods are abutted to the first connecting rods. Wherein, the dwang passes through the wind spring and rotates with the connecting plate and be connected, and the both ends of dwang all have the mounting groove that is used for supplying the wind spring to place promptly, have still movably inserted the fixed pin in the mounting groove, fixed pin and connecting plate fixed connection, the one end and the mounting groove inner wall fixed connection of wind spring, the other end twines outside the fixed pin with fixed pin fixed connection wind spring. In one aspect, the extending direction of the rotating rod is perpendicular to the material moving direction of the discharging end of the material conveying belt. In one scheme, a plurality of through holes for inserting and fixing bolts are clamped on the connecting seat. The bolt is inserted into the through hole to realize the fixed connection of the connecting plate and the external object. In one scheme, a lifting conveyor belt is arranged at the discharge end of the material conveyor belt, the lifting conveyor belt is provided with a horizontal section and a lifting section, the horizontal section is positioned below the discharge end of the material conveyor belt, the lifting section and the discharge end of the material conveyor belt are arranged at intervals, a material homogenizing roller is arranged on the lifting section, and the material homogenizing roller and the lifting section are arranged at intervals. The material homogenizing roller is driven by the driving motor, is rotationally connected to the lifting section by the bracket, and the rotation direction of the material conveying roller is opposite to the rotation direction of the lifting conveying belt. The material falls into the lifting conveyor belt from the discharge end of the material conveyor belt, and is lifted to the lower-stage processing mechanism by the lifting conveyor belt. In one scheme, the device further comprises a buffer piece, wherein the buffer piece is located between the lifting section and the discharging end of the material conveying belt, and the buffer piece is arranged at intervals from the horizontal section.
