Description

Liquid material package equipment

Technical Field

The application relates to the technical field of packaging machinery, in particular to liquid material packaging equipment.

Background

In daily life and production activities, various liquid materials are required to be used. In order to facilitate the use of people, packaging containers such as disposable liquid material packaging bags and the like are invented by people and widely popularized and used.

In the related art, a common disposable liquid material packaging bag generally includes two packaging films, and edges of the two packaging films are bonded or pressed together, so that a sealed liquid storage cavity is formed between the two packaging films, and the liquid storage cavity is used for filling liquid materials. When the disposable liquid material packaging bag is used, the packaging bag needs to be torn open by hands or cut by using a tool, so that an opening communicated with the liquid storage cavity filled with the liquid material is formed in the packaging bag, and the liquid material flows out from the opening through squeezing or pouring. Such a disposable liquid material packing bag has a drawback in that, when the packing bag is torn or cut, the liquid material filled in the packing bag is easily stained on the hand of a user or a tool for cutting the packing bag, causing contamination of the hand and the tool. And, the size of wrapping bag open-ended is also difficult to control, and the opening is too little, can lead to the difficult outflow of liquid material, and the opening is too big, can lead to the liquid material to flow too much, causes inconvenience for the user.

In order to solve the above-mentioned drawbacks, those skilled in the art have devised a disposable liquid material packaging bag (hereinafter referred to as "easy-opening liquid material packaging bag") capable of forming an opening by bending, as shown in fig. 1-4, the easy-opening liquid material packaging bag 700 is composed of a hard film 710 and a soft film 720, the hard film 710 is bonded or press-sealed to the edge of the soft film 720, so that a liquid storage cavity 730 filled with liquid material is formed between the hard film 710 and the soft film 720, and the hard film 710 has a thinned portion 740 with a thickness thinner than other areas of the hard film 710. In use, the user may bend the bag to break the hard film 710 at the thinned portion 740 to form an opening through which the liquid material in the reservoir 730 may flow or be squeezed. In this way, the liquid material does not get stuck on the user's hand or on the tool used to cut the package. Also, the size of the opening of the packing bag can be adjusted by changing the size and shape of the thinning part 740, thereby ensuring that the opening of the packing bag is controllable.

However, no suitable packaging apparatus is available that can automatically and efficiently produce the above-mentioned easy-opening liquid material packaging bag. So that the above-mentioned easy-opening liquid material packaging bag is difficult to be put into the market for use in batches, and the defects of the disposable liquid material packaging bag mentioned in the related art still exist generally.
