Description

A package blocking device for material bag steering and conveying

technical field

The invention belongs to the technical field of conveying machinery, in particular to a bag blocking device for turning and conveying material bags.

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 conveying and palletizing the material bag, the material bag has to go through at least two 90° turning and conveying, and the material bag turns 90° from one conveyor to the other conveyor, and a bag blocking device needs to be installed at the turning point. The bag blocking device is used at the turning point of the material bag conveying. It is an important part to ensure the smooth turning and conveying of the material bag. Normal conveying forward, so the performance of the bag blocking device determines whether the conveying of the bag is smooth or not, and plays a very important role in the conveying process of the bag.

At present, the commonly used bag blocking devices include unpowered arc bag blocking board and powered electric bag blocking device. The arc bag blocking board has a simple structure, and the inertia of the bag forces the bag to turn passively. The bag blocking effect is very important for on-site installation and debugging. The requirements are relatively high, and if the handling is not good, it is easy to cause bag blocking. Now it has been gradually replaced by a powered electric bag stopper. The electric bag stopper is essentially a vertically placed conveyor, which drives the material bags to turn through the operation of the conveyor belt. The supporting structure of the head and tail wheels has two kinds of support at the upper and lower ends and the suspension support at the lower part, both of which have defects such as a slightly complicated structure, difficult replacement of the support bearings of the head and tail wheels, difficulty in tensioning, easy deviation of the belt, and relatively expensive prices. The patented electric bag blocking device for bagged material steering and conveying (Patent No. 201120486610) relates to an electric bag blocking device. The wheel support bearing and the tail wheel tensioning device are closed on the inner side of the support plate by the transmission belt. The bearings are not easy to replace, the tail wheel is difficult to tension, and the transmission belt needs to be customized and the price is relatively high.
