Problems solved by technology

[0002] The rotary tablet press in the prior art mainly uses the upper and lower pressing wheels to drive the mold to complete the stamping and forming. In the process of processing the product, the different thickness of the product needs to be realized by switching the mold. The disadvantage is that On the one hand, manufacturers need to reserve different molds, which increases the production cost, and takes a long time to switch molds, resulting in a decrease in production efficiency; on the other hand, the pressure wheel is prone to shaking during the production process, resulting in low processing accuracy

Embodiment

[0008] A pressure adjustment mechanism for the lower pressure wheel, comprising an eccentric shaft 9, the middle part of the eccentric shaft 9 is connected to the lower pressure wheel 8 through a bearing 5, and a worm wheel 6 is connected to the end of the eccentric shaft 9, and the worm wheel 6 Connected with a worm shaft 2, through the transmission of the worm shaft 2, the worm wheel 6 can be driven to rotate, so that the eccentric shaft 9 can rotate smoothly, thereby driving the lower pressure wheel 8 to rotate. In this embodiment , because the eccentric shaft 9 can drive the lower pressing wheel 8 to be adjusted up and down in the process of circular motion. As we all know, there is a forming mold on the tablet press, and through the change of the upper and lower positions of the lower pressing wheel 8, Different pressures can be given to the forming mold to meet the processing requirements of products with different thicknesses. In order to play a protective role, in this...

Abstract

The invention discloses a pressure adjusting mechanism of a downwards-pressing wheel. The pressure adjusting mechanism comprises an eccentric shaft, and the downward-pressing wheel is connected to the middle of the eccentric shaft though a bearing; a worm wheel is connected to the end of the eccentric shaft; the remaining part of the eccentric shaft is sleeved with a shaft sleeve, and is connected with a machine body through the shaft sleeve; the worm wheel is connected with a worm wheel shaft, a set screw is implanted into the machine body, and the worm wheel and the machine body are integrally connected through the set screw; and a connecting rod is connected with the worm wheel shaft, and a handle is arranged at the end of the connecting rod. Vertical motion of the downward-pressing wheel is achieved through the eccentric shaft, so that the requirement for different machining thicknesses is met; and meanwhile, the downward-pressing wheel is driven through the worm wheel to stably rotate, and therefore the aim of improving the machining accuracy is achieved.

Description

technical field [0001] The invention relates to the technical field of rotary tablet presses, in particular to a pressure adjustment mechanism for adjusting lower pressure rollers. Background technique [0002] The rotary tablet press in the prior art mainly uses the upper and lower pressing wheels to drive the mold to complete the stamping and forming. In the process of processing the product, the different thickness of the product needs to be realized by switching the mold. The disadvantage is that On the one hand, manufacturers need to reserve different molds, resulting in increased production costs, and it takes a long time to switch molds, resulting in reduced production efficiency; on the other hand, the pressure wheel is prone to shaking during the production process, resulting in low processing accuracy. Contents of the invention [0003] In order to solve the above technical problems, we propose a pressure adjustment mechanism for the lower pressure roller, which ...
