Discussion on the process of automatic drug packaging machine
1、 Market background.
In recent years, China's pharmaceutical industry has experienced rapid development, with a constantly expanding market size and the emergence of new products. However, due to the high prices of drugs, many related industries have benefited greatly from it. However, with the increasing supervision of drug prices by the government, their profit margins will gradually shrink, which is bound to attract the attention of many pharmaceutical companies to cost control.
Improving drug production efficiency and reducing packaging costs are inevitable choices for enterprises. Many pharmaceutical companies have begun to attach importance to the construction of automated packaging production lines and have introduced automated packaging machines, which not only improve packaging efficiency, reduce packaging labor costs, but also improve hygiene standards. The present invention will also directly affect the production process requirements of packaging paper boxes.
The pharmaceutical industry is a cardboard printing industry, and this change will directly affect the market prospects of packaging enterprises in the next 3-5 years. Therefore, companies with keen vision in the industry have begun to study the processing technology of machine automatic packaging of cardboard boxes and chassis products.
2、 Equipment and principles of packaging boxes.
To study the process of packaging box products, it is natural to first understand the working principle of automatic packaging machines. General automatic cartoning machines can automatically load medicine bottles, tablets, ointments, and instructions into folding paper boxes, and complete the lid action. Some fully functional automatic cartoning machines are also equipped with additional functions such as sealing labels or heat shrink bags.
Secondly, the automatic packaging machine usually has three entrances for feeding materials: instructions for use, bottle entrance, and machine packaging box entrance. The entire process from box feeding to final packaging and forming can be roughly divided into four stages: unloading, opening, loading, and closing. The unloading action is usually carried out by a suction cup, which sucks the paper box from the feeding port and enters the main line of the box body downwards. The paper box is fixed by a guide rail clamp, and then a push plate is used to push open the paper box. At the same time, two cards that can move forward are raised from below, clamping the sides of the box from the front and back directions. This way, the box opens at a right angle and then moves forward to the filling area. After filling the filling area, the machine mechanism folds the ears into the left and right guide rails, and then performs a closing action.
The mechanism before closing the lid is to first bend the tongue of the cardboard box, then a push plate pushes the box cover, pushes the tongue into the box, and then fastens the lock. The closing action is a key action, and its completion is closely related to the precision of the cardboard box structure and machine adjustment.
In addition, the working principles and mechanism actions of the equipment provided by different packaging machine suppliers are different, so corresponding structures need to be adopted.
When general packaging machinery suppliers provide equipment to pharmaceutical enterprises, they provide a structural diagram of the packaging box based on the product specifications and dimensions, which is an important process basis for producing packaging packaging.
3、 The main factors affecting the effectiveness of packaging on the machine.
1. Carton construction.
In terms of its structure, it can be divided into two types based on the position of the box, namely co insertion and reverse insertion. Various box shapes require different directions of movement for the closure, and the corresponding structure of the packaging machine is naturally different. The quality of the box structure is closely related to the production level of the die-cutting plate. The accuracy of the size of the die-cutting plate, the model of the cutting line, and the installation effect can all cause differences in the structure of the paper box, thereby affecting the effectiveness of the paper box on the machine. Therefore, choosing a suitable die-cutting supplier is crucial.
2. The cardboard box is straight.
The stiffness of the box mainly affects the box shape effect of the cardboard box when opened on the machine, such as whether the shape is square. Ambiguity will affect the progress of the paper box and the bagging process, causing the machine to jam.
The stiffness of the box mainly comes from the stiffness of the paper surface and the paper surface treatment process. Oiled products generally cause a decrease in the stiffness of the cardboard box, while products with film and full version UV have an increase in stiffness compared to the original; The stiffness of the product after oil polishing is also better, but the cardboard is more brittle and the fibers are easy to break.
In addition, moisture-proof protection of cardboard boxes is also very important. Paper easily absorbs moisture in natural air. The moisture content of paper is directly proportional to the humidity and exposure time of the air. Moisture is one of the important factors affecting the stiffness of the paper surface, therefore, the paper should have a moisture-proof protection effect.
3. Carton opening situation.
What is the opening performance of the cardboard box? That is, the difficulty of using relevant machinery to shape the paper box on an automatic box loading machine.
The actions of various box loading machines to open the box are different. Some devices are equipped with auxiliary box opening mechanisms, which can pre fold the paper boxes to reduce the mechanical force required for box opening and prevent deformation of the box due to excessive compression. If there are no such mechanical devices on the box body, pre folding treatment is required when producing cardboard boxes.
In addition, it is necessary to stick the box adhesive in an appropriate amount. If there is too little adhesive, it will cause false sticking of the paper box, while if there is too much adhesive, it will cause internal sticking.
4. Debugging of packaging machinery.
The operation of the packaging machine is generally completed by personnel from pharmaceutical factories, who have limited ability to adjust the movement based on the structure of the cardboard box. During the operation of the packaging machine, jamming problems often occur, ultimately due to the mismatch between the operation of the mechanism and the structure of the cardboard box. For packaging production enterprises, pharmaceutical factories are God. We cannot demand cooperation from others. Only by adapting ourselves and adjusting the structure of the cardboard box according to the condition of the sample to adapt to the machine's movements can we solve the problem. If experts in the field of sample box testing equipment are involved, it is also a good idea to suggest that the dispatcher make necessary adjustments to the sample box.
