Background
The plaster is an external preparation for pasting on the skin, after the plaster is prepared by the traditional way, the plaster dough is taken and placed in a container, the mixture is melted on water bath or slow fire, fine materials are added and stirred evenly, a certain amount of plaster is taken by a bamboo stick and placed on kraft paper or plaster cloth, but along with the social development, the demand of the plaster is increased, the traditional plaster preparation can not meet the demand, particularly, the manual plaster spreading speed is too slow, the efficiency is low, and when a worker manually spreads a coating film, the plaster inevitably contacts with the skin, and the gas in the plaster heating process can also cause harm to the human body.
According to the patent CN1839798A, the black plaster is thinly prepared, the black plaster thinning method and the black plaster thinning equipment break through the traditional original preparation method of manually spreading the plaster on the backing material, and the mechanized continuous production of black plaster forming is realized. However, the equipment can only process solid ointment blanks, if the processed ointment is fluid, the ointment can flow uncontrollably in all directions when the ointment is extruded by the temperature-controlled tabletting device, so that the spreading area and the thickness are not easy to control, and meanwhile, the ointment can be adhered to the temperature-controlled tabletting; when the blank forming device punches, the ointment can be adhered to the blank forming device; the drug loading rate cannot be controlled. In addition, in the stamping forming process of the blank forming device, if the adhesion force of the ointment and the blank forming device is greater than the sum of the adhesion force of the ointment and the backing material and the self gravity, the ointment can adhere to the blank forming device and can be separated from the backing material, so that the whole production process is influenced.
The patent CN201064559Y black plaster quantitative spreading and film spreading integrated machine not only can accurately control the dosage of each plaster, but also can spread a film on the surface of the plaster, so that the surface of the plaster is smooth, the appearance is attractive, the plaster is not easy to volatilize, and the oil is not easy to dry. However, the machine needs manual operation in the process of coating and forming the mud flat, the coating area and the thickness are not easy to control, and the production efficiency is low; workers are inevitably contacted with the ointment in the manual film covering and flattening processes, and gas generated in the heating process can also have adverse effects on the health of the workers.
