Discussion on the packaging process of pharmaceutical machine

I. market background

in recent years, China's pharmaceutical industry has made considerable development, the market scale has been expanding, and new products are emerging in endlessly. Although many related industries have benefited a lot from the high price of drugs for a long time, as the state strengthens the supervision of drug prices, its profit space will gradually shrink, which will inevitably lead to the attention of many pharmaceutical companies to cost control

it is an inevitable choice for enterprises to improve the efficiency of pharmacy and reduce the cost of packaging. Many pharmaceutical enterprises began to pay attention to automated packaging production lines and have introduced automated cartoning machines. On the one hand, they can improve packaging efficiency, reduce packaging labor costs, and on the other hand, they can also improve health standards. The use of this automatic cartoning machine will also have a direct impact on the process requirements of packaging cartons

as a paper packaging enterprise printing medicine boxes, this change in the pharmaceutical industry can directly affect the market prospects of packaging manufacturers in the next 3 to 5 years. Therefore, enterprises with keen vision in the industry have begun to study the process of machine automatic packaging carton - machine packaging carton products

II. Packaging equipment and principle

to study the process of packaging products, it is natural to first understand the operation principle of the automatic cartoning machine. First of all, the usual automatic cartoning machine can automatically load the medicine bottle, medicine plate, ointment, etc. and instructions into the folding carton, and complete the action of box capping. Some fully functional automatic cartoning machines also have additional functions such as pasting sealing labels or heat shrinkable wrapping

secondly, the feeding of the automatic cartoning machine is generally divided into three entrances: the entrance of the manual, the entrance of the medicine bottle and the entrance of the machine package box. The whole process from box feeding to final packaging and molding can be roughly divided into four stages (as shown in Figure 1): lower the box, open (as shown in Figure 2), fill, and close the cover. The action of lowering the carton is usually to draw a carton from the carton feeding port by a suction cup, and then descend to the main line of cartoning. The carton is fixed by a guide rail detent and opened by a push plate. At the same time, two movable detents will rise from below, clamp the side of the carton from the front and rear directions, so that the box can be opened at a right angle and moved forward to the loading area. After filling the filling area, the mechanism of the machine will fold the ears into the left and right guide rails, and then close the cover

before closing the lid, the mechanism will first bend the tongue of the carton, and then a push plate will push the lid to bend, so that the tongue can be inserted into the box and the latch can be fastened. The closing action is a key action, and the completion is closely related to the structure of the carton and the accuracy of machine adjustment

in addition, the working principle and mechanism action of the equipment provided by different cartoning machine suppliers will be different, so the structure of the machine package box should match it

generally, when cartoning machine suppliers provide equipment to pharmaceutical enterprises, they will provide the structural drawings of machine packaging boxes according to the specifications and dimensions of their products, which is an important process basis for the production of machine packaging boxes

III. main factors affecting the effect of machine package box

1 Carton structure

from the perspective of structure, the machine package box can be divided into two types according to the position of the box cover: the same plug type and the reverse plug type (as shown in Figure 3). Different box types require different action directions of closing the lid, and the corresponding cartoning machine structure is naturally different. The structure of carton is closely related to the production level of die-cutting plate. The accuracy of the size of the die-cutting plate, the model of the knife line, and the loading effect will all cause the differences in the structure of the carton, which will more or less affect the effect of the carton on the machine, so it is very important to select a suitable die-cutting plate supplier

2. Carton stiffness

carton stiffness mainly affects the opening effect of the carton when it is put into the machine, such as whether the molding is square. Improper molding will affect the forward movement and filling process of the carton, resulting in jamming

the stiffness of the carton mainly comes from the stiffness of the paper and the surface treatment process. Watered oil products are usually made of composite materials made of extremely strong fibers in polymers (plastics) to reduce the stiffness of cartons; The stiffness of coated and full-scale UV products will be improved compared with the original; The stiffness of oil polished products is also good, but the paper is brittle and the fiber is easy to break

in addition, the paper box is easy to be aged and degraded, resulting in discoloration, strength reduction and other problems. It is also very important to store it. Paper is easy to absorb moisture in the natural air, and its moisture content increases in the same direction with the humidity of the air and the exposure time. The moisture content of paper is one of the key factors affecting the stiffness of paper, so the paper needs moisture-proof protection

3. Carton opening performance

what is carton opening performance? That is, the difficulty of forming cartons by using relevant mechanisms on the automatic cartoning machine

not used in automotive products. Compared with the subject connecting to the old belt, the same cartoning machine has different actions to open the box. Some equipment has an auxiliary opening mechanism, which can pre fold the carton, so as to reduce the mechanical force required for opening the carton and prevent the box from deforming due to excessive extrusion. If there is no such mechanism on the cartoning machine, the pre folding process is required when producing cartons

in addition, the glue used to stick the box must be appropriate. Too little will cause false sticking of the box, and too much will cause internal sticking

4. The adjustment of the cartoning machine

the operation of the cartoning machine is usually carried out by the personnel of the pharmaceutical factory. Their ability to adjust the action of the mechanism according to the carton structure is relatively limited, which often causes the problem of machine jam during the operation of the cartoning machine. In the final analysis, it is because the mechanism operation does not match the carton structure. For packaging manufacturers, pharmaceutical factories are God. When we can't ask others to cooperate with us, we can solve the problem only if we adapt to them and adjust the structure of the carton according to the sample test machine situation, so as to adapt to the action of the machine. Of course, if there are experts in equipment to participate in the sample box test machine, it is also a good way to suggest the master of machine adjustment to make necessary adjustments

IV. conclusion

in order to successfully complete the packaging action of the packaging box on the cartoning machine, the die-cutting supplier and the cartoning machine supplier need to participate in the design and processing of the carton. Joint cooperation can form a "win-win" situation for pharmaceutical manufacturers, packaging manufacturers and cartoning machine suppliers
