Description

Paper corner protector conveying device

Technical Field

The present invention relates to the field, and more particularly, it relates to a paper corner protector transport device.

Background

The paper angle bead is a paper products of a shape similar to the angle steel, and mainly used places and plays the cushioning effect in cuboid form's article edges and corners, can reduce the harm of jolting for cuboid form article, and in the production process of paper angle bead, the last step is to use paper angle bead guillootine to cut into the length that meets the requirements with the paper angle bead guillootine, after cutting, the paper angle bead that cuts need be transported to the packing station and is packed, can use conveyor this time.

The conveying equipment in the prior art is mostly a belt type conveying belt, and the belt type conveying belt is easy to purchase and is simple and easy to use. However, when the belt conveyor conveys the paper corner protectors to the packaging station, the paper corner protectors generally deviate and cannot be well stacked together, and the paper corner protectors need to be stacked together and then packaged by an operator during packaging, which is labor-consuming. The main reason for the deviation is that a section of paper corner protector cut by the cutting machine has a certain deviation when falling on the belt conveyor, and the paper corner protector also has a certain deviation when falling on the packaging station from the belt conveyor, so that the two deviations are superposed, and the paper corner protector is scattered when falling on the packaging station.

Aiming at the phenomenon, the Chinese patent with the patent authorization publication number of CN208868974U discloses a paper corner protector receiving device, and the technical key point of the receiving device is that a guide rod is arranged on a conveying belt, the paper corner protector can slide down along the guide rod after coming out of a cutting machine, and under the auxiliary action of the guide rod, the paper corner protector is not easy to deviate, and the paper corner protector receiving device is also provided with a height adjusting mechanism for adjusting the height of one end of the guide rod so as to be suitable for the production of paper corner protectors with different sizes and models.

In fact, only the guide rod is needed to be capable of calibrating the position of the paper corner protector falling from the cutting machine to the conveying device, the phenomenon that the paper corner protector is conveyed to a packaging station to be scattered can be greatly reduced, the guide rod is found in the actual use process, if the situation of 'stacking plates' occasionally occurs when some shorter paper corner protectors are produced, the situation is that the paper corner protector is shorter due to the fact that the guide rod is longer, the shorter paper corner protector does not contact with the conveying belt at the beginning of the downward sliding for a certain distance, the paper corner protector simply slides downwards by virtue of gravity, and the phenomenon of 'stacking plates' can occur if one paper corner protector is clamped on the guide rod and does not fall down in time.

Therefore, there is a need to design a paper corner protector transport device to overcome the above problems.
