Description

Technical Field

[0001] The invention relates to an improved liquid food composite paper container finished product process and production line, and is particularly suitable for composite paper packages. Background Art

[0002] At present, composite paper packaging is a packaging product used for liquid food. The six-layer composite paper packaging composed of paper, aluminum and plastic can effectively block air and light, making the consumption of milk and beverages more convenient and safer, and extending the shelf life, achieving higher packaging efficiency.

[0003] Composite paper packages have found a good balance between protection and emotional needs. Compared with plastic bottles and glass bottles, brick-shaped and pillow-shaped composite paper packages have a relatively large volume ratio, and this packaging shape is easier to pack, transport and store. From a technical point of view, composite paper packages are six-layer composite paper packages composed of paper, aluminum and plastic, which can effectively block air and light, which are the killers that easily cause milk and beverages to deteriorate. Therefore, the small composite paper package makes the consumption of milk and beverages more convenient and safe, and has a longer shelf life, achieving higher packaging efficiency. CN201720753102.X A composite paper packaging processing equipment cannot achieve automated assembly line production.

[0004] Although the existing CN201710866981.1 A liquid food packaging container, packaging material and filling method provides a filling method, in actual production, the bottle cap is installed later, which causes secondary contamination and requires secondary disinfection, which easily causes contamination and affects the quality of the liquid.

[0005] In order to achieve the goal of capping before filling, the rooftop bag adopts a roof structure and designs a bottle cap assembly on one side of the roof. However, the bottle cap opening size is limited, and it is impossible to design a large-opening bottle cap on the top. In addition, due to the existence of the roof structure, it is impossible to arrange it neatly during transportation or palletizing, which wastes space and makes it impossible to completely empty the liquid in the container. How to remove the roof to facilitate palletizing or transportation and reduce waste, and also to increase the diameter of the bottle mouth has become a technical problem that needs to be solved urgently.

[0006] Compared with the traditional structure, the present invention reduces the upper folding ears, reduces the composite paper consumables, reduces the leakage caused by too much contact surface, and reduces waste gas emissions, thereby greatly simplifying the process, facilitating operation, eliminating the side gap of the container during stacking, avoiding the disadvantages of the traditional folding ears that scratch the hands, breaking the monopoly of foreign multinational companies on technology, and compared with the injection molding process, it is short in time and high in efficiency, can achieve sealing and bonding installation after filling, and eliminates the cleaning process of injection molding residues, avoids secondary pollution, avoids the existence of draft angles, and avoids the residual injection molding smell. The injection molding process requires a prefabricated opening at the bottom or side of the container to facilitate the mold to enter the container cavity from the prefabricated opening, cool and demold after shaping, remove the mold, and then disinfect and rinse and other complex processes. The present invention does not require a prefabricated opening to complete the above process. The lid of the present invention is not contaminated by chemical glue. Summary of the invention

[0007] The technical problem to be solved by the present invention is generally to provide an improved liquid food composite paper container finished product process and production line, which cleverly sets the cover process before or at the same time as filling, avoids secondary pollution caused by filling, reduces the number of disinfection times, ensures the taste of the beverage, and improves production efficiency. Compared with the existing patented technology, it improves a set of more convenient and controllable specific production line processes. (The top of the container refers to the part where the bottle mouth of the finished container is located, the bottom is the part that contacts the ground after the container is placed, and the rest is the side.) The pre-finished state of the container is the state of the composite paper before the container is formed, such as the coil, sheet (4), semi-finished folded part and other container pre-forming states; indentations, punching holes, and side / end portions can be prefabricated. The film layer can be a conventional anti-penetration film of composite paper such as aluminum film and film. The sealing machine can be a folding machine with folding function, a bonding machine, a welding machine, a thermoplastic machine, an adhesive machine and other general equipment or mechanism components. Of course, the use of conventional equipment such as overlapping installation equipment or riveting presses is an equivalent replacement for the sealing machine. The peeling machine is a common equipment for composite paper, which is used to peel off the redundant layers of multi-layer composite paper to expose the corresponding layers so as to perform corresponding work, such as bonding through the pulp layer, sealing through the film layer 40, etc. It is common knowledge that the folding machine can integrate the sealing function or add a sealing mechanism after the folding machine or on one side. The top opening of the container can be round, square or conventional. The folding can adopt conventional folding, indentation, and bonding schemes can adopt the corresponding process steps of the existing technology or their improvements or equivalent deformations. Sealing is a combination of sealing and connection. The drinking mouthpiece (15) and the cap piece (19) can be hard materials or soft materials. For example, conventional materials such as food-grade hard plastics, aluminum films, etc.

[0008] To solve the above problems, the technical solution adopted by the present invention is:

[0009] An improved process for producing a composite paper container for liquid food comprises the following steps:

[0010] Step 13, folding and sealing the pre-finished container parts while retaining the top opening of the container;

[0011] Regarding the filling step, it is divided into α) scheme or β) scheme;

[0012] Step 2, 2α) filling the container with liquid through the top opening of the container or 2β) through the drinking mouth piece of the drinking mouth assembly of the container before the finished product;

[0013] Step three, 3α) after filling through the top opening of the container, the top opening of the container is sealed with the drinking port assembly; 3β) after filling through the drinking port piece, the cap piece is installed on the drinking port piece.

[0015] The bag folding machine folds and seals the pre-finished state of the container and retains the top opening of the container;

[0016] The drinking opening assembly of the container includes a bottle cap assembly sealed on the top opening of the container; the bottle cap assembly includes a drinking opening piece and / or a cap piece;

[0017] Regarding filling, there are two options: α) or β);

[0018] As a parallel solution, α) the filling machine fills through the top opening of the container, and a drinking mouth assembly sealing machine is arranged after the filling machine; or β) the filling machine fills through the drinking mouth piece, and a drinking mouth piece sealing machine for installing the drinking mouth piece on the top opening of the container is integrated between the filling machine and the bag folding machine or before the bag folding machine or on the filling machine or on the bag folding machine, and a cap piece pressing machine for installing the cap piece on the drinking mouth piece is integrated with or arranged after the drinking mouth piece sealing machine.
