Flexible upper prestressing adjusting device

Abstract

The invention discloses a flexible upper prestressing adjusting device which aims to increase material pressing time and adjust the prestressing amount. The device comprises an axial screw, a spring, a prestressing wheel stand, a rivet, an upper track disc, a gasket, a prestressing wheel, a prestressing wheel sleeve, a lock screw, a check ring and a forced filling oil cup. The prestressing wheel stand is connected with the upper track disc through the rivet, the gasket is installed between the prestressing wheel stand and the upper track disc, and the spring sleeves the axial screw. The axial screw is fixed on the upper track disc after penetrating the prestressing wheel stand, the prestressing wheel sleeve sleeves the prestressing wheel stand after being installed in an inner hole of the prestressing wheel, the check ring is fixed through the lock screw after sleeving the outer side of the prestressing wheel, and the forced filling oil cup is installed on the prestressing wheel stand. The flexible upper prestressing adjusting device can serve as an upgrading product for a rigid structure prestressing adjusting device for a high-speed rotating type sheeter.

Description

technical field [0001] The invention relates to a pharmaceutical machine, in particular to a flexible upper pre-compression adjustment device on a rotary tablet press in the pharmaceutical machine. Background technique [0002] In the pharmaceutical machinery industry, the machine that compresses solid particles into tablets is usually called a tablet press machine, and the machine that installs the die on the turntable and rotates with the turntable is called a rotary tablet press machine. In the low-speed rotary tablet press, there is generally no pre-compression device, while in the high-speed rotary tablet press, due to the high speed, a pre-compression adjustment device is installed to increase the compression time of the material. All the upper preload adjustment devices currently on the market adopt rigid structures, and the preload position is difficult to adjust. When the gap between each preload wheel and the upper punch is too small and the preload is large, the u...

AI Technical Summary

Problems solved by technology

At present, all upper preload adjustment devices on the market adopt rigid structures, and the preload position is difficult to adjust. When the gap between each preload wheel and the upper punch is too small and the preload is large, the upper punch and the track There will be hard friction between them, which will easily damage the upper punching nail and the upper track; and when the gap between each preloading wheel and the upper punching nail is too large, the preloading effect cannot be achieved, so we must try to solve the problem of adjusting the preloading amount to increase material compression time
