Turning mechanism

Abstract

The invention discloses a turning mechanism, comprising a rack, and a feeding channel and a guiding channel are arranged on the rack. The turning mechanism is characterized in that the length of the upper end of the guiding channel is matched with the length of a material, a stopping part matched with the material is arranged in front of the feeding channel, the stopping part comprises an ejectorrod which moves forward and backward, and the rear end of the ejector rod is matched with the material. The turning mechanism ensures that the materials entering the guiding channel have the flat endsat the front and grooved ends at the back, and the materials are oriented in the same direction.

Description

technical field [0001] The invention relates to a U-turn mechanism, in particular to a U-turn mechanism for solid glue. Background technique [0002] The traditional packaging machine uses manual feeding, and the staff make the materials place in the same direction when feeding, but the cost of manual feeding is relatively high. In order to realize automatic feeding, the applicant applied to the Chinese Patent Office for the invention titled "Rotary Paper Card Seal" The invention patent of "feeding mechanism of plastic packaging machine", the authorized announcement number is CN206691446U, the feeding mechanism makes the direction of the material uniform through the U-turn device, and specifically discloses the following content: The U-turn device includes a connected feed end and a discharge end , the feed end is correspondingly arranged at the lower end of the conveyor belt; the middle part of the feed end is provided with a balance bar, and the balance bar is used to make...

[0002] The traditional packaging machine uses manual feeding, and the staff make the materials place in the same direction when feeding, but the cost of manual feeding is relatively high. In order to realize automatic feeding, the applicant applied to the Chinese Patent Office for the invention titled "Rotary Paper Card Seal" The invention patent of "feeding mechanism of plastic packaging machine", the authorized announcement number is CN206691446U, the feeding mechanism makes the direction of the material uniform through the U-turn device, and specifically discloses the following content: The U-turn device includes a connected feed end and a discharge end , the feed end is correspondingly arranged at the lower end of the conveyor belt; the middle part of the feed end is provided with a balance bar, and the balance bar is used to make the workpiece fall by touching the balance bar when the workpiece falls. The head falls downwards, and the inner wall of the U-turn device is also provided with two guide slopes, and a guide channel for a single workpiece that is gradually narrowed from top to bottom is formed between the two guide slopes. The discharge end is connected

This patent utilizes the difference in weight between the front and back of the material, and through the balance bar, the heavy end falls into the guide channel downward, so that the direction of the material entering the guide channel is uniform, but the front and rear weights of the solid glue are not much different, so it is difficult to ensure where the solid glue is. The end of the glue enters the guide channel downwards, so the direction of the solid glue entering the guide channel cannot be unified. Therefore, for this kind of material with uniform front and rear weights, it can only be fed manually.
