Description

A reversing device for material bag diversion conveying

technical field

The invention belongs to the technical field of conveying machinery, in particular to a reversing device for bag diversion conveying.

Background technique

In my country's production-oriented enterprises such as flour, starch, oil, feed, chemical fertilizer, salt and cement, most of their product materials are in the form of bags. During production, the materials must be packaged into bags and sent to the warehouse for stacking. Various enterprises are widely used. The form of conveyor conveying and palletizer stacking and palletizing. In the process of single-line conveying of material bags, there are many situations where it is necessary to divert conveying to two warehouses or to each span of a single warehouse with more than two spans. This requires setting up a diversion conveyor, and according to the needs of warehouse palletizing or continuing to convey in a straight line forward, Or 90° turn to rear delivery.

In view of the need for diversion conveying, the common method is to install a movable bag blocking device on the diverting conveyor. When it needs to be conveyed in a straight line, turn the movable bag blocking device to one side; Rotate to the bag-blocking position, the material bags turn 90° after being blocked and arrive at the conveyor perpendicular to the shunt conveyor, realizing 90°turning and conveying. In order to ensure a good blocking and turning effect, the movable bag blocking device often adopts a powered electric bag blocking device, and the rotation switching is either manually switched, or powered by a motor drive or an electric push rod drive for power control switching. If manual switching is used, workers need to climb to the support platform to rotate and switch regularly, which is not only cumbersome to operate, but also unsafe, and must be shut down to affect the efficiency of conveying and palletizing; if power control switching is used, an additional set is required The power drive device will complicate the structure of the bag blocking device, increase the cost, and increase the power loss during production, increasing the production cost.
