Technical Field
The utility model belongs to the technical field of pharmaceutical machinery, be applicable to pharmacy trade preforming count and open to opening of tablet press and stop control, in particular to preforming count controlling means.
Background
The tablet press used in the prior production can only repeat the tablet pressing work after being started, can not know how many tablets are pressed, and can not control how many tablets need to be pressed and then stop working. The original working principle is that a cam (or eccentric wheel) connecting rod mechanism is used to make the upper punch and the lower punch produce relative movement to press tablets. The production method has the advantages of intermittent production, intermittent feeding, intermittent sheet discharging and low production efficiency.
The working steps can be decomposed into: the lower punch part (with the working position upward) extends into the middle die hole from the lower end of the middle die hole to seal the bottom of the middle die hole; filling medicine into the middle mould hole by using a feeder; the punch part of the upper punch (the working position of the punch part is downward) falls into the middle die hole from the upper end of the middle die hole and descends for a certain stroke, and the medicinal powder is pressed into tablets; the lift-out hole is punched. The lower punch rises to push the tablet out of the middle die hole, and the tablet pressing process is completed; the undershoot falls to the home position, ready for the next fill.
In the prior art, the tablet pressing work can be repeated after the tablet pressing machine is started in production and use, the number of pressed tablets cannot be known, and the work can be stopped after the number of pressed tablets is controlled. The prior art needs to rely on the staff to count the tablet by manual work, or the tablet press discharge gate is connected with the vibration dish or the conveyer belt that are provided with the counter thereby to realize the counting function, but can not in time control tablet press stop work.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve the technical problem that exists among the known art and provide a preforming count controlling means, can accurate control preforming quantity and the work of accurate control tablet press.
The utility model comprises the following technical scheme: a tablet pressing counting control device comprises a counter and a magnetic sensor which are arranged on a tablet pressing machine, wherein a permanent magnet is fixedly arranged on the outer side surface of a cam of the tablet pressing machine, and the magnetic sensor is fixedly arranged on the outer side of the permanent magnet through an outer bracket; the magnetic sensor is connected with a counter, and an output contact of the counter is connected with a control power supply of the tablet press through an intermediate relay.
When the cam operates, each time the permanent magnet passes through the magnetic sensor, a signal is triggered to the counter, and the counter counts one number; when the tabletting work meets the set quantity, the counter outputs a signal to the intermediate relay, the intermediate relay controls the tablet press to stop tabletting, and meanwhile, the counter gives an alarm to remind an operator to fill.
Preferably, the cam is an eccentric wheel.
Preferably, a connecting rod is installed on the cam, and a pressing sheet punch is fixedly installed on the connecting rod.
Preferably, the horizontal projection position of the magnetic force sensor on the cam is the position of the permanent magnet.
Preferably, the permanent magnet is located near the edge of the cam, and the permanent magnet is large in displacement and not prone to causing mistaken touch on the magnetic sensor in the rotating process.
Preferably, the distance between the permanent magnet and the magnetic force sensor is 8-10 mm.
Preferably, the bottom of the outer bracket is fixedly arranged on the tablet press.
Preferably, the counter is provided with an alarm horn, a display screen and a control button.
Preferably, the control buttons include a set button and a reset button. The setting button is used for setting different tabletting quantities according to different filling quantities. The tablet press machine can work according to the set number, stop working after reaching the specified number, and continue working after the counter is reset by pressing the reset button for a long time, so as to perform the tablet pressing of the next process.
The utility model has the advantages and positive effect:
1. the utility model discloses a permanent magnet and magnetic force sensor carry the count signal to count for the counter, and the cam drives the preforming drift up-and-down motion when driving the permanent magnet pivoted and accomplishes the preforming, can accurate control preforming quantity.
