Material bag shaping and flattening device

Abstract

The invention relates to a material bag shaping and flattening device. The material bag shaping and flattening device comprises a machine frame and a pressure roller which is arranged horizontally, wherein a rotatable rotating shaft is hung at the lower part of the machine frame; two rotating arms are vertically and fixedly connected to the rotating shaft; a mounted bearing is arranged at one end, far away from the rotating shaft, of each rotating arm; each mounted bearing is connected with a shaft head of the pressure roller; guide rails are respectively and fixedly arranged on the two sides of the machine frame; each guide rail is provided with an arc-shaped guide groove; a guide post which is provided with external screw threads is arranged on each rotating arm; each guide post penetrates through the corresponding guide groove; screwing nuts which are matched with the guide posts are respectively arranged on the two sides of each guide rail; the screwing nuts are clamped and fixed to the guide rails. By the structure, the material bag shaping and flattening device is simple in structure; the guide posts are arranged on the rotating arms, the guide rails provided with the arc-shaped guide grooves are arranged on the machine frame, and the height of the guide posts are adjusted through the screwing nuts, so that the height of the pressure roller is adjusted; therefore, the shaping effect is enhanced, and the phenomenon of material blockage is avoided.

Description

technical field [0001] The invention relates to a material bag shaping and flattening device, in particular to a material bag shaping and flattening device applied in an automatic palletizing production line. Background technique [0002] In the automatic palletizing production line, the upright bags are put down on the conveyor belt through the bag dumping process, and often need to go through the flattening process to shape and flatten the bags. In the prior art, a rotatable pressure roller is usually installed horizontally on the conveyor belt, and the passing bag is shaped and flattened by the pressure roller. However, there are certain defects in this method. The height of the pressure roller is fixed and cannot be adjusted, resulting in The shaping effect is not very ideal. At the same time, when the material bag is thick and bulky, it is easy to cause material blocking. However, the shaping and flattening machines that can adjust the height of the pressure rollers th...

Problems solved by technology

In the prior art, a rotatable pressure roller is usually installed horizontally on the conveyor belt, and the passing bag is shaped and flattened by the pressure roller. However, there are certain defects in this method. The height of the pressure roller is fixed and cannot be adjusted, resulting in The shaping effect is not very ideal. At the same time, when the material bag is thicker and larger, it is easy to cause material blocking.

However, there are shaping and flattening machines on the market that can adjust the height of the pressing rollers, and their structures are often more complicated and the cost is higher.
