Medical plastic-aluminum packaging mold
Technical Field
The invention belongs to the technical field of medicine production equipment, and particularly relates to a medical aluminum-plastic packaging mold.
Background
The encapsulated medicine is generally a powder or granules which is irritating to the esophagus and gastric mucosa, or a medicine which is bad in taste, easy to volatilize, easy to be decomposed by saliva in the oral cavity, and easy to be inhaled into the trachea. The medicines are filled into capsules, so that the medicine property of the medicines is protected from being damaged, and the digestive organs and the respiratory tract are protected. Removal of the capsule shell may result in loss of the drug, waste of the drug, and reduced efficacy. In addition, some medicines need to be dissolved and absorbed in intestines, the capsules protect the medicines from being damaged by gastric acid, and after the production of the capsules is finished, the capsules placed in a medicine plate need to be covered by an aluminum film through a packaging mold, and then the capsules are packaged after heat sealing.
When an aluminum film is too large during working of the conventional packaging die, redundant rim charge needs to be cut off, after the redundant rim charge is cut off, the edge charge also needs to be taken off after a wrapped medicine plate is taken off, so that the influence on the next heat sealing work is avoided, and the working efficiency is greatly influenced.
