Air-blowing type labeling device

Abstract

An air-blowing type labeling device comprises an air distribution box, an air blowing cavity and an air suction cavity are formed in the air distribution box, a plurality of air pipes are fixedly mounted on the lower surface of the air blowing cavity, a plurality of air suction holes are formed in the lower surface of the air suction cavity, the air suction cavity communicates with the outside through the air suction holes, and the air blowing cavity communicates with the outside through the air pipes; an air inlet device and a fan are fixedly mounted on the upper surface of the air distribution box, the air inlet device comprises an air inlet core, an air inlet control valve and an air inlet pipe, one end of the air inlet core penetrates through the air distribution box and fixedly communicates in the air blowing cavity, the other end of the air inlet core is fixedly mounted at the air outlet end of the air inlet control valve, and the air inlet pipe is fixedly mounted on the air inlet section of the air inlet control valve; and the air suction end of the fan communicates with the air suction cavity. The defects in the prior art are overcome, and the label can be automatically attached to the rear surface of a product package on the basis of not making contact with the product. Therefore, secondary pollution can be prevented; and label sucking and label blowing are independent systems, convenience and high efficiency are achieved, and air source switching is avoided.

Description

technical field [0001] The invention relates to the technical field of labeling devices, in particular to an air blowing labeling device. Background technique [0002] The added value of domestic fruit and vegetable products is too low, and the loss is large. The loss rate of fresh produce in China is 20%-30%, and the loss rate of fruit and vegetable in Japan is less than 3%. The technological content of fruit and vegetable products is low. At present, the packaging process of fruit and vegetable products is usually mainly manual. One of the links is weighing and labeling. The electronic scale is manually placed, the weight is weighed, and the label is manually pasted. For the transfer warehouse of fruit and vegetable products, the order quantity is large, and manual completion is likely to cause secondary pollution. [0003] The mechanical arm is used to label the fruit and vegetable products. Due to structural design problems, it must be in contact with the product, whic...

AI Technical Summary

Problems solved by technology

For the transfer warehouse of fruit and vegetable products, the order quantity is large, and manual completion is likely to cause secondary pollution

[0003] Using a robotic arm to stick labels on fruit and vegetable products, due to structural design problems, it must be in contact with the product, which is easy to damage the fruit and vegetable products

And it will also cause secondary pollution of fruit and vegetable products. For example, the packaged products are strawberries, durians, peaches, peppers, etc., and the shelf life of the products will be shortened if they are in contact with the product labeling.

And the mechanical arm labeling usually uses cylinders to realize the process, so it takes time to return and the speed is slow
