Automatic spread coating machine of black plaster

Abstract

The invention discloses an automatic spread coating machine of black plaster. The automatic spread coating machine of the black plaster comprises a base, a support, a cylinder, mounting materials, a mounting rolling drum, a laminating rolling drum, rolling rubber rollers, a pressing plate, a mold pressing device, a punching and cutting device and a waste material recovering hopper. The mounting materials are stuck between two rolling rubber rollers and drive the two rolling rubber rollers to move forwards depending on friction force. A stepping motor is connected with the rolling rubber rollers through a coupler and provides power for equipment. An input end of a driver of the stepping motor is connected with an output end of a control center through cables, and the output end of the driver of the stepping motor is connected with the stepping motor through cables. The control center is a programmable logic controller (PLC) and controls the spread coating machine of the black plaster to automatically operate. The automatic spread coating machine of the black plaster is completely free of manufacturing the black plaster through manual operations. The plaster processed can be solid and can also be fluid. In the spread coating process, manpower needs not participating in, and fitness is prevented from being affected when the plaster is heated and is in contact with people. A plurality of procedures such as laminating, spread coating, cutting and packaging and waste-material recovery of the plaster can be finished with one machine.

Description

technical field [0001] The invention relates to a pharmaceutical equipment, in particular to a plaster production equipment, in particular to a black plaster automatic spreading machine. Background technique [0002] Black plaster belongs to an ancient dosage form of external medical treatment in the motherland, and its curative effect is certain. However, with the development of modern pharmacology and pharmaceutical preparations, the preparation process and equipment of black plaster also need continuous innovation. [0003] Patent CN1839798A black plaster thinning method and black plaster thinning equipment, black plaster thinning equipment in this invention breaks the traditional original production method of manually spreading the plaster on the backing material, and realizes the black plaster thinning equipment. Mechanized continuous production of plaster molding. However, this equipment can only process solid paste. If the processed ointment is fluid, the ointment wi...

Problems solved by technology

However, manual operation is required for film coating and molding of this machine in the process of tidal flats. The spread area and thickness are not easy to control, and the production efficiency is low. Workers will inevitably come into contact with the ointment during the manual film coating and flattening process, and the heat produced during the heating process The gas can also adversely affect the health of workers
