Problems solved by technology

However, since the precompression pressure of the compression molding device of the high-speed tablet press on the tablet blank is likely to change and deviate, if the precompression pressure does not meet the specific precompression pressure setting of the specific formula material fixed value, and can not be well adjusted and controlled, it will affect the quality of the tablet, so it is necessary to monitor the pre-compression pressure in real time; in addition, for the production of different tablets, the thickness of the tablet, The ingredients are different. At this time, the size of the pre-compression pressure needs to be re-tested and adjusted to meet the requirements of the tablet preparation process for the size of the pre-compression pressure.

Embodiment 1

[0040] This embodiment is a single discharge model, such as figure 1 and figure 2 As shown, the high-speed tablet press of the present embodiment is a high-speed rotary tablet press, including:

[0041] The turntable 1 includes a middle punching plate 16, an upper punching plate 15 respectively arranged above the middle punching plate 16, and a lower punching plate 17 arranged below the middle punching plate 16; mod 19;

[0042] The feeding device 9 is arranged above the middle punching plate 16, and is used to add formula materials into the middle mold 19; the transmission mechanism 2 is used to drive the turntable 1 to rotate around the vertical axis Z.

[0043] The press forming mechanism 3 includes multiple pairs of upper punch rods 18 and lower punch rods 20 that are respectively held on the upper punch plate 15 and the lower punch plate 17 and can slide up and down relatively reciprocatingly; 20 a pair of punches at opposite ends.

[0044] The transmission mechanism...

Embodiment 2

[0057] The difference between this embodiment and embodiment 1 is that, as Figure 6 As shown, it is a schematic diagram of the work flow station of the model for pressing the double-layer tablet. The tablet press for making the double-layer tablet has the first layer feeding station 221 of the double-layer tablet model, the double-layer tablet The first layer quantification station 231 of the ply model, the first ply pre-pressing station 241 of the double-layer model, the first layer sampling station 261 of the double-layer model; the second layer of the double-layer model Layer feeding station 222, double-layer sheet model second layer quantitative station 232, double-layer sheet model double-layer sheet pre-pressing station 242, double-layer sheet main press forming station 252, double-layer sheet output Sheet station 262, the first ply feeding device 91 of the double-ply machine located at the first ply feeding station 221, the second layer of the double-ply machine locate...

Abstract

The invention relates to tablet equipment, in particular to a high speed rotating tablet press which comprises a forming die, a feeder apparatus, a transmission mechanism and a forming mechanism. The forming die is arranged for moving along a work route which is provided with a feeding station, a pre-pressing forming station, a main pressing station and a tablet outlet station. The forming mechanism is provided with at least one stamping device and a pre-pressing pressure detecting device which is arranged on the pre-pressing forming station and for detecting a pre-pressing pressure value generated by the forming mechanism. Based on comparing a detected value of the pre-pressing pressure with a set value of pre-pressing pressure, the pre-pressing pressure of the forming mechanism can be regulated via a controller. The invention can prevent the influence on product quality caused by deviation of pre-pressing pressure and can be applied to manufacturing different products.

Description

technical field [0001] The invention relates to tablet pressing equipment, in particular to a high-speed tablet pressing machine. Background technique [0002] High-speed tablet press is a machine that presses various granular raw materials into round tablets or special-shaped tablets through continuous rotation. It is the basic equipment for processing various granular raw materials into tablets in pharmaceutical, chemical, food and other industrial departments. [0003] In the past, when tablet presses were used to form and compress tablets, the quality of the formed tablets was different due to the different pressing and forming processes. Chinese patent CN2686845Y discloses a mechanism for measuring the tableting force with a pressure sensor. The mechanism for measuring the tableting force is mainly used in a rotary tableting machine. The strain gauge pressure sensor is used to measure the deformation of the strain gauge to measure the pressure of the pressing wheel. , ...
