Problems solved by technology

However, during its production, a single cylinder is used for feeding, and the drug film machine must stop and wait for each feeding, and the working rhythm is relatively slow; at the same time, the width of the die head of this drug film machine is limited, and simply increasing the width of the die head will produce problems. The phenomenon of uneven medicine, so the coating width of this medicine film machine ointment is also limited; so the efficiency of this medicine film machine still needs to be further improved

Embodiment 1

[0011] Embodiment 1: the medicine film machine of the present embodiment is as figure 1 Shown, horizontal screw extruder 2 is housed on frame 8. The screw tail end of the screw extruder 2 is supported in the bearing 6 and is fixedly connected with the synchronous toothed wheel. The bearing 6 is installed on the frame 8 through a bracket. The synchronous toothed wheel is engaged with the driving wheel of the motor 9 by the synchronous toothed belt 7 . Motor 9 is fixedly installed in the rear portion of frame 8. The front end of the screw extruder 2 is supported on a vertical strut. The barrel of screw extruder 2 rear ends is shaped on the inlet hole of A pressing medicine cylinder 10 and B pressing medicine cylinder 5 connected by A non-gate control valve 3 and B non-gate control valve 4 . This medicine pressing device mainly is made up of A medicine pressing cylinder 10, B medicine pressing cylinder 5, A cylinder 12, B cylinder 11. The upper end of the drug pressing cyli...

Abstract

A medicine film machine with double cylinders is used for pressing medicine. A frame is provided with a screw extruder. The back end of the screw extruder is communicated with the outlet of a medicine pressing cylinder. The fore end of the screw extruder is provided with a die head. The front part of the die head is a downward flare opening, thus forming a flat downward outlet of a medicine film. The screw thread on a screw rod of the screw extruder is arranged as an unequally spaced thread, the thread pitch of the unequally spaced thread is thick at the front and thin at the back and the thread depth thereof is shallow at the front and deep at the back. The medicine film machine is characterized in that two medicine pressing cylinder are arranged in parallel; the outlets of two medicine pressing cylinders are respectively provided with a not gate control valve and communicated with the screw extruder through the not gate control valve. The width of the die head of the screw extruder is increased to 12cm. A uniform stream structure is arranged inside the die head. The uniform stream structure is that a divisional island is arranged on a drug channel in the die head. The medicine film machine with double cylinders can realize the automatic mass production of Chinese medicine plaster, so the labor intensity is evidently reduced and the work efficiency is improved. In addition, the medicine film machine with simple structure can widen the coating width of the plaster and avoid uneven medicine discharging.

Description

technical field [0001] The invention relates to a pharmaceutical machine, in particular to a medicine film machine for plastering traditional Chinese medicine with two cylinders for pressing medicine. Background technique [0002] Traditional Chinese medicine plaster is a commonly used external drug dosage form. In large-scale industrial production, the general method of making traditional Chinese medicine plaster is: firstly grind the medicinal materials into fine powder or extract them, mix them with natural rubber, and then scrape them on the base cloth and dry them. Sliced. The Compound Nanxing Pain Relief Ointment adopts a new technology, and its film is made by mixing the fine powder of medicinal materials with the matrix and then using a film machine. China's No. 03131514.3 invention patent discloses a drug film machine. The structure of the drug film machine is: a horizontal screw extruder is installed on the frame; the rear end of the screw extruder communicates wi...
