Description
Technical Field
The utility model relates to a wrapping bag technical field, more specifically say, it relates to a valve port bag of full-automatic bagging-off.
Background
The technical working conditions are as follows: the valve port filling machine is the main type of the current industrial packaging equipment, can meet the requirements of fast, efficient and fine packaging of sheet, granular, conventional powder or superfine powder through different feeding modes such as air conveying or screws and the like, and is widely used for packaging in building material, chemical industry, food and pharmaceutical industry. The valve bag matched with the valve port filling machine for use also becomes a main packaging bag type meeting heavy packaging in different industries.
With the development of science and technology, the realization of automation and unmanned packaging of industrial packaging is one of the main development directions of industrial heavy packaging, and the realization of full-automatic bagging, automatic filling and robot stacking in the product packaging process is a key element for realizing automation and unmanned packaging, and is also a key element for removing human interference, improving production efficiency, reducing labor cost and controlling the product to be manufactured into a process.
The automatic bag feeding and automatic filling links not only realize automation and intellectualization to the filling machine, but also the valve port packaging bag needs to be matched with filling equipment to realize bag body smoothness, especially mouth smoothness and opening integrity required by automation, so as to finish the bag suction, valve port opening and valve port butt joint bagging in the automatic bag feeding process. The more the opening of the valve bag tends to be round, the more the success rate of butting the valve bag with the valve port of the device is facilitated. Therefore, the valve bag opening circular rate is realized by optimizing and adjusting materials and processes in the valve bag production process, and the improvement of the automatic bag feeding rate has important significance.
Introduction of the prior art: the valve port type of the valve port bag used for automatic bag feeding is divided into an internal valve port and an external valve port, wherein the valve port is completely arranged inside the folded bottom of the bag body and is called as the internal valve port, and part of the valve port is arranged outside the folded bottom of the bag body and is called as the external valve port.
The process types of valve port forming are mainly divided into two types, one type is sheet material, and the valve port is formed by overlapping (sheet valve), namely the sheet material is overlapped into a cylinder shape by overlapping seams to form the valve port; the other is a cylinder valve process directly adopting a tubular valve port.
Certainly, in order to improve the stiffness of the valve port and improve the roundness of the valve port in the opening process, a double-layer valve port or a composite valve port is adopted, the stiffness of the valve port is improved by adopting the composite valve port, the opening is facilitated, and meanwhile, the heat sealing material is coated on the inner side of the valve port to meet the heat sealing process requirement of the valve port.
The technical problem is as follows: the overlapped lap seam is generally larger than 10mm by adopting a flap valve lap joint process in the prior art, and the roundness approaching performance of materials in the lap seam area and other areas is inconsistent to form an irregular circle in the opening process of a valve port due to the fact that the thickness of the materials at the lap seam is twice of that of the materials in other areas, so that the bag feeding rate is influenced;
the cylinder valve process is adopted: although the cylinder valve meets the consistency of valve port materials, in the bag making process, the valve port cutting section requires that the thickness of two layers of valve ports is directly cut off, the abrasion of cutting equipment is large, and for composite valve ports such as film spraying or film covering, the valve port is extremely easy to be stuck after being cut off due to the fact that the inner side of the valve port is made of the film material with the heat sealing function, and the valve port is prone to be stuck, so that the normal opening is caused, and the bag feeding fails.
SUMMERY OF THE UTILITY MODEL
To the sheet valve overlap joint technology, the section of thick bamboo valve that provide in the background art lead to the valve mouth to glue the sticky filling bag that leads to of bag rate not high technical problem because of processing technology factor, the utility model discloses set up the breach on the canned valve port, the breach is located the top of filling valve port central line, and during going up the bag, the filling valve port is opened along the breach bending, and it is good to tend the circularity to reach bag, go up the purpose that the bag rate is high in quick.
