The workbench 2 is fixedly arranged on the top of the base 1.

The top of the worktable 2 is provided with a mounting hole 201, and the turntable 3 rotates and rotates in the mounting hole 201. Preferably a seal is maintained between the turntable 3 and the table 2 to facilitate better cleaning of the crushed tablet pieces.

The motor 4 is fixedly arranged in the base 1, and the power output end of the motor 4 is connected with the power input end of the rotary table 3. Specifically, a driving gear 8 is fixedly mounted on a power output shaft of the motor 4, a driven gear 10 is fixedly mounted at the bottom of the rotary table 3 through a connecting shaft 9, and the driving gear 8 is meshed with the driven gear 10.

A plurality of feeding holes 301 are formed in the rotary table 3, the plurality of feeding holes 301 are uniformly distributed around the rotation center line of the rotary table 3, and the inner diameter of each feeding hole 301 is larger than the outer diameter of each tablet and smaller than two times of the outer diameter of each tablet. Specifically, the feed hole 301 is a through hole having an inner diameter larger than the outer diameter of the tablet and smaller than twice the outer diameter of the tablet, so that only one tablet can be fed into the feed hole 301 at a time. Preferably, the inner diameter of feed hole 301 is slightly larger than the inner diameter of feed cartridge 5, so that the tablets in feed cartridge 5 fall into feed hole 301.

The feed cylinder 5 is located above one side of the turntable 3. The inner diameter of the feeding barrel 5 is larger than the outer diameter of the tablet and smaller than the sum of the outer diameter and the thickness of the tablet. I.e. the inner diameter of the feed cylinder 5 is slightly larger than the outer diameter of the tablets, in order to ensure that the tablets are arranged orderly one by one in the feed cylinder 5 without the feed cylinder 5 jamming due to two or more tablets being juxtaposed.

And the distance between the bottom of the feeding cylinder 5 and the top of the worktable 2 is larger than the thickness of the tablet, and the distance between the bottom of the feeding cylinder 5 and the top of the rotary table 3 is smaller than the thickness of the tablet. Preferably, the distance between the bottom of the feed cylinder 5 and the top of the table 2 is slightly greater than the thickness of the tablets, so as to ensure that during the rotation of the turret 3 only one tablet, and not the other, is taken away at a time inside the feed hole 301.

And the discharge hole of the feeding barrel 5 corresponds to the feeding hole 301. Specifically, the center of the discharge port of the feed cylinder 5 corresponds to an arc line drawn by the rotation of the center of the feed hole 301 around the turn table 3.

The cylinder 6 is located above the other side of the turntable 3. The other side as referred to herein means the side opposite to the feed cylinder 5. The bottom of the power output end of the cylinder 6 is fixedly provided with a lower pressure head 11. The lower pressure head 11 corresponds to the feeding hole 301. Specifically, the center of the lower presser head 11 corresponds to an arc drawn by the rotation of the center of the feed hole 301 around the turn table 3.

The pressure sensor 7 is located below the turntable 3 and corresponds to the lower press head 11. Specifically, the pressure sensor 7 is fixedly installed in the table 2, and is opposed to the lower ram 11.

And the worktable 2 is provided with a discharge hole 202, and the discharge hole 202 corresponds to the feeding hole 301 and is larger than the feeding hole 301.

When the tablet feeder is used, tablets are firstly put into the feeding barrel 5, then the motor 4 is started, the motor 4 drives the rotary table 3 to rotate, and the feeding holes 301 formed in the rotary table 3 rotate along with the rotation. When any one of the feeding holes 301 corresponds to the discharge port of the feeding barrel 5, the tablets in the feeding barrel 5 fall into the feeding hole 301. The tablet that falls into the feed cylinder 5 then moves with the turntable 3 under the action of the turntable 3.

When any one of the feeding holes 301 with tablets moves to the lower part of the lower pressure head 11, the motor 4 stops running, the air cylinder 6 starts and moves downwards with the lower pressure head 11 until the tablets in the feeding hole 301 are crushed. The pressure sensor 7 transmits the pressure at this time to the computer, and the computer performs statistics and stores the pressure. After that, the cylinder 6 is retracted and the motor 4 is activated, bringing the turret 3 to continue its rotation and carrying away the crushed tablet pieces which flow out of the discharge opening 202 when the feed opening 301 corresponds to the discharge opening 202.

And repeating the operation to finish the hardness detection of the tablets in batches.

In one embodiment, further comprising: inductor 12 and sensor plate 13.

The inductor 12 is positioned below the cylinder 6 and corresponds to the feeding hole 301. In particular, the inductor 12 is located on a radial extension of the turntable 3. And the inductor 12 is electrically connected to a controller (not shown in the drawings).

The number of the sensing pieces 13 is multiple, and the sensing pieces correspond to the feeding holes 301 one by one. The sensing piece 13 is positioned on one side of the feeding hole 301 departing from the rotation center line of the rotary table 3 and is fixedly connected with the rotary table 3.

And the motor 4 and the cylinder 6 are electrically connected to the controller.

Thus, during the process of driving the turntable 3 to rotate by the motor 4, the sensing piece 13 rotates along with the turntable. When the sensor 12 senses the sensing piece 13, at the moment, exactly one feeding hole 301 with the tablets corresponds to the lower pressing head 11, the controller controls the motor 4 to stop, and the air cylinder 6 starts to start the crushing operation.

After crushing the controller air cylinder 6 contracts and the motor 4 starts.

This structure facilitates control of stopping and operation of the motor 4 and the cylinder 6.

In one embodiment, further comprising: a cleaning box 14, wherein the cleaning box 14 and the base 1 are arranged in a drawer structure and are communicated with the discharge hole 202.

The crushed tablets flow into the cleaning box 14 through the discharge hole 202 to be collected, and when the tablet waste in the cleaning box 14 is fully collected, the cleaning box 14 is taken out.

This mechanism facilitates the cleaning of the tablet fragments.

The working principle of the utility model is as follows:

when the tablet feeder is used, tablets are firstly put into the feeding barrel 5, then the motor 4 is started, the motor 4 drives the rotary table 3 to rotate, and the feeding hole 301 formed in the rotary table 3 and the induction sheet 13 arranged on the rotary table 3 rotate together. When any one of the feeding holes 301 corresponds to the discharge port of the feeding barrel 5, the tablets in the feeding barrel 5 fall into the feeding hole 301. The tablet that falls into the feed cylinder 5 then moves with the turntable 3 under the action of the turntable 3.

When the sensing piece 13 senses the sensor 12, a feeding hole 301 with tablets moves to the lower part of the lower pressing head 11, the controller controls the motor 4 to stop running, the air cylinder 6 is started, and the lower pressing head 11 is driven to move downwards until the tablets in the feeding hole 301 are crushed. The pressure sensor 7 transmits the pressure at this time to the computer, and the computer performs statistics and stores the pressure. After that, the cylinder 6 is retracted and the motor 4 is activated, bringing the turret 3 to continue its rotation and carrying away the crushed tablet pieces which flow out of the discharge opening 202 when the feed opening 301 corresponds to the discharge opening 202.

This practicality type can test the hardness of tablet in succession to efficiency of software testing has been improved.
