An automatic bag opening device

Abstract

The invention discloses an automatic unbagging device. The automatic unbagging device comprises a machine base, a bag conveying mechanism arranged on the machine base, a sucker unbagging mechanism and an expanding mechanism. The sucker unbagging mechanism is arranged on one side of the machine base, and the expanding mechanism is arranged on the other side of the machine base. The bag conveying mechanism comprises an air draft conveying belt for conveying bags and a first servo motor for driving the air draft conveying belt to run. Multiple air draft openings are formed in the air draft conveying belt. The sucker unbagging mechanism comprises a lower sucker, an upper sucker arranged above the lower sucker, and a sliding block connected with the upper sucker. The lower sucker is fixed to one side of the machine base through an installing frame, and a position inductor is arranged on the installing frame. The expanding mechanism comprises multiple sets of expanding assemblies. Each set of expanding assembly comprises an expanding rod, a rotary air cylinder, and an expanding air cylinder connected with the expanding rod. Through cooperated use of the sucker unbagging mechanism, the expanding mechanism, the position inductor and the bag conveying mechanism, automatic unbagging and bagging are achieved, therefore, the labor cost and working difficulty are reduced, and production efficiency is improved.

Description

technical field [0001] The invention relates to the field of automatic packaging, in particular to an automatic bag opening device. Background technique [0002] At present, in the bagging process of powdery materials such as fertilizers and feed, most of them need manual participation, such as manual completion of bagging and other processes, but in some existing bagging machines, the process of automatic bag opening has not been well received. A good implementation usually requires manual bag picking and opening, or it is necessary to arrange people to keep an eye on the bag picking and opening conditions, and manual adjustments are required from time to time, which is laborious and laborious, with low production efficiency and high cost, and the existing automatic There is still a big deficiency in the bag opening device, and the bag opening effect cannot be reached. [0003] The published Chinese patent literature announcement number is CN2700244B, which records a kind ...

Problems solved by technology

[0004] Although the structure of the above-mentioned patent is relatively simple, relying on the adhesive force of the adhesive tape to the plastic film of the packaging bag to open the bag, it is easy to cause the adhesive force of the adhesive tape to the plastic film of the packaging bag to disappear or decrease due to various reasons. Unable to achieve the bag opening effect, resulting in unnecessary losses
