Roller type bagging and opening holding device

Abstract

The invention relates to the technical field of packaging machine equipment. The roller type bagging and opening holding device comprises a bag conveying table, a bagging roller frame, a roller framedriving piston, bagging roller mechanisms, an edge conveying opening and V-shaped opening holding devices, wherein each bagging roller mechanism comprises suction rollers, a T-shaped three-way pipe, anegative pressure piston cylinder, a negative pressure piston return spring, pull wires and suction roller rotating pre-tightening springs. According to the roller type bagging and opening holding device, opening, bagging and opening holding operation on a bag opening of a packaging bag is achieved at the same time through the suction rollers, the control operation process is simplified, fault reasons can be prone to position for overhauling during troubleshooting operation, and meanwhile the material scattering leakage rate is effectively reduced due to the fact that the bag opening of the packaging bag is turned over by the suction rollers.

Description

Technical field: [0001] The invention relates to the technical field of packaging machine equipment. Background technique: [0002] The bagging machine is one of the commonly used equipment in the production process of bag packaging products filling and packaging. Its purpose is to drag the open packaging bag after the preparation is completed to the filling and feeding port. [0003] Most of the existing bagging machines use the working principle of mechanical arm clamping or mouth opening dragging. The clamping mechanical arm structure is simple and the manufacturing cost is low, but the function is single. Usually, it only has the function of dragging the opened packaging bag to the conveyor. The material port itself does not have the function of opening the packaging bag. It is necessary to install an independent packaging bag opener on the front bag conveying device, and after the packaging bag is dragged to the material conveying port, a complete set of multiple fixing...

Problems solved by technology

[0003] Most of the existing bagging machines use the working principle of mechanical arm clamping or mouth opening dragging. The clamping mechanical arm structure is simple and the manufacturing cost is low, but the function is single. Usually, it only has the function of dragging the opened packaging bag to the conveyor. The material port itself does not have the function of opening the packaging bag. It is necessary to install an independent packaging bag opener on the front bag conveying device, and after the packaging bag is dragged to the material conveying port, a complete set of multiple fixing surfaces is required to cooperate. The mouth holding device realizes the fixing of the packaging bag to cooperate with the filling

Therefore, it and its upstream and downstream supporting equipment as a whole have the defects of complex control logic structure, high accuracy requirements for operation time, and complicated maintenance and troubleshooting procedures
