Embodiment Construction

[0021] First, the powdery raw material is quantitatively added into the porous forming mold through vibration, and then the forming mold is put into the mold base to fix the position. Start the equipment, set the process operation parameters such as pressing pressure and pressure holding time, and the mold is completely closed under the automatic control of the control system. After holding the pressure for a certain period of time, the ejector mechanism ejects the implant particles and collects them in a vacuum under the action of vacuum. Then open the mold to the upper limit position, take out the template, and complete a working cycle.

[0022] The above are only preferred embodiments of the present invention, and it should be pointed out that those skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, and these all belong to the present invention. scope of protection.

Abstract

The invention discloses a drug pressing machine for preparing small-diameter granular implants from powdery raw materials, including a machine frame, a mold frame, a hydraulic system, a forming mold, a vacuum drug collecting device, a control system and the like. The molding die is composed of a die, a punching pin, a punching pin fixing plate, and a guiding device. The vacuum drug collection device includes components such as a vacuum pump, a vacuum channel, and a drug collection box, which can realize the automatic collection of preparation particles. The control system is composed of programmable controller, photoelectric sensor, force sensor and instrument, etc., which can precisely control the pressure, mold movement direction and speed, time and position. The medicine pressing machine uses the powdery mixture as the raw material, presses it into granular implants with a diameter of 0.5-2mm, and puts them into the medicine collection box through vacuum suction, and the whole process is automatically completed. This medicine pressing machine can adjust various process parameters, mold hole number and hole diameter according to needs, and press dozens to hundreds of granular implants at a time. The extruded particles have high hardness, stable shape and smooth appearance.

Description

technical field [0001] The invention relates to the field of pharmaceutical equipment, in particular to a drug pressing machine for preparing small-diameter granular implants from powdery raw materials. Background technique [0002] Solid implant is a long-acting drug preparation with sustained and controlled release. It can be implanted into the local lesion of the patient through surgery or under the guidance of imaging equipment. By increasing the drug concentration and action time in the local lesion, the curative effect can be improved and the toxicity can be reduced. purpose of side effects. For the convenience of implantation, the implant is often made into small particles with a diameter of 0.5-2mm, and implanted into the patient's lesion through an implant needle. Conventional tablet presses complete feeding, pressing, demolding, and collection at different positions of the continuously rotating equipment. In order to ensure fast and quantitative feeding, the fluid...
