Description

Double-clamping-plate bag clamping device Technical Field The utility model relates to the technical field of powder bagging machines, in particular to a double-clamping-plate bag clamping device. Background In the debugging production practice of powder bagging machines, traditional single-clamp-plate bag clamps expose significant problems. When the single clamping plate bag clamp is adopted, the bagging manipulator can be loosened after the single clamping plate clamps the bag opening, otherwise, the bag can fall off. Specifically, when the single clamping plate clamps the bag opening, the bag slides in the bagging mechanical arm, and as the bagging mechanical arm and the bag need to be kept in a clamping state (otherwise, the bag is easy to fall off in the moving process), and the contact surface of the bagging mechanical arm and the bag is generally designed into a saw-tooth shape for increasing static friction force, if the bag slides in the bagging mechanical arm, the bag opening is easily torn, or the bagging mechanical arm and the single clamping plate form internal resistance through the bag, so that the bagging fails. In addition, the length variation A of the bag mouth between the two ends of the bagging manipulator is larger before and after the clamping of the single clamping plate, and the elongation percentage of the packaging bag in the industries of powder, feed, plastics, seeds and the like cannot meet the large length variation. Therefore, reducing the value of A becomes a key to fundamentally improve the success rate of bagging. In view of the application of the device in the powder field, in order to ensure good tightness, powder is prevented from being sprayed out from a bag opening during discharging and packaging, the length of the single clamping plate needs to surround the discharging opening as much as possible, the value of A cannot be reduced by reducing the length of the single clamping plate like particle material treatment, and the double clamping plate bag clamping device is specially designed for solving the contradiction through deep analysis and observation.
