Description

[0002] At present, most tablets and capsules in major hospitals and pharmacies are packaged in aluminum foil. When these drugs are distributed to patients in wards, the packaging shells of tablets and capsules often need to be removed. If the drug packaging shells are removed manually, it will not only be inefficient and unable to meet the medication needs, but will also cause pollution to the drugs.

When the demand for drugs is large, frequent manual adjustments not only waste time, but also adjust slowly. It is difficult to accurately control the spacing of the compressed tablets, and it is inevitable that the drugs will be damaged due to improper manual adjustment of the spacing. Patent CN109094916A discloses a stable automatic drug stripping machine, which realizes the automatic stripping of capsules or tablets through the mutual cooperation between the rolling rubber wheel and the equalizing device, but it is still difficult to adjust the spacing of the split pieces according to the spacing between the tablets in the drug plate.

At the same time, this information is converted into operation instructions through data processing, and the driving motor rotates, driving the driving gear to rotate, and the driving gear engages with the surface of the driven gear, thereby driving the movement of the connecting rod mechanism through gear transmission.

[0033] 3) The structure of the telescopic connecting rod unit, the movable base and the driving member is reasonably arranged, and the position adjustment is convenient. The driving member can quickly drive multiple movable bases to move evenly, thereby driving multiple compressed tablets to adjust the spacing. BRIEF DESCRIPTION OF THE DRAWINGS

The method of achieving the toward or relative movement of the two clips 2 by rotating the knobs 4 on the two clips 2 is as follows: there is a groove in the middle of each clip 2 for accommodating the edge of the medicine plate 28, the knob 4 passes through the clip 2, the knob 4 and the clip 2 are connected by a thread, the bottom of the knob 4 abuts against the guide groove 27 on the surface of the operating table 26, and the depth of the knob 4 inserted into the guide groove 27 can be adjusted by rotating the knob 4, and the bottom of the knob 4 presses the surface of the guide groove 27 to achieve positioning. When positioning, the edge of the medicine plate 28 abuts against the side of the knob 4, and the edge of the medicine plate 28 is perpendicular to the medicine pressing roller 21. The clip 2 only positions the edge of the medicine plate 28 in a direction parallel to the medicine pressing roller 21, and does not limit the position perpendicular to the direction of the medicine pressing roller 21. The medicine plate 28 can be close to or away from the medicine pressing roller 21.

[0077] The stripping machine also includes a medicine grain collection box 1 for collecting peeled tablets, an empty medicine board collection box 13 for collecting discarded medicine boards 28, and a guide plate 15 for transferring discarded medicine boards 28; the medicine grain collection box is located directly below the medicine stripping mechanism, and the empty medicine board collection box 13 is located directly below the movable base. The guide plate is fixedly arranged below the medicine pressing workspace, and can be specifically arranged at an angle, with the upper portion arranged below the medicine pressing workspace to receive discarded medicine boards 28 dropped from the upper portion, and the lower portion can be connected to the bottom plate 24, and is arranged opposite to the empty medicine board collection box 13 so that the dropped discarded medicine boards 28 slide down the guide plate 15 and fall into the empty medicine board collection box 13.

[0078] The second drive motor 20 includes a second drive motor body and an output shaft of the second drive motor connected to the second drive motor body. One end of the medicine pressing roller 21 is connected to the output shaft of the second drive motor. The second drive motor body is fixedly connected to the first side plate 22 .

[0079] The outer surfaces of the medicine pressing roller 21 and the medicine pressing tablet 14 are provided with textures.

[0080] The specific working steps and principles of this embodiment are:

[0081] Load the medicine plate 28 between the clips 2, and make the first row of tablets and one side edge of the clip 2 on one side close to and align with the 0 scale line, tighten the knob 4 so that the clip 2 limits the medicine plate 28, and the other side clip 2 moves and limits the other side of the medicine plate 28.

[0082] The compressed pills 14 are moved to the specified position by the driving member, and then the second driving motor 20 causes the compressed pill roller 21 to start rotating. The compressed pills enter the pill stripping mechanism through the friction force on the surface of the compressed pill roller 21. The medicine plate 28 is between the compressed pill roller 21 and the compressed pills 14. The stripped pills fall into the pill collecting box 1 from the gaps between adjacent compressed pill tablets 14, and the discarded medicine plates 28 enter the empty medicine plate collecting box 13 through the guide plate 15.

[0083] The staff can continuously put in the same type of medicine plates 28 to realize continuous medicine stripping. If different types of tablets are to be stripped, repositioning is required.

[0088] Turn on the switch 5, the image sensor 3 identifies the medicine plate information and transmits the identified medicine plate information to the controller, the controller controls the first drive motor 12 to move the compressed medicine tablet 14 to the corresponding position through the gear set and the ball screw 6, and then the controller controls the second drive motor 20 to drive the compressed medicine roller 21 to rotate. The image sensor is an existing conventional technical means and will not be described here. For example, a CCD image sensor.

[0089] The specific working steps and principles of this embodiment are:

[0090] Load the medicine plate 28 between the clamps 2, and make the first row of tablets and one side edge of the clamp 2 on one side close to and align with the 0 scale line, tighten the knob 4 so that the clamp 2 clamps the medicine plate 28, and the other side clamp 2 moves and clamps the other side of the medicine plate 28.

[0091] The switch 5 provided on the first side plate 22 is turned on, and the stripping machine starts to work.

[0092] The image sensor 3 identifies the information of the medicine plate 28 and transmits it to the controller. The controller controls the first drive motor 12 of the driving member to move the movable base 10 through the gear set and the ball screw 6, and further drives the compressed medicine tablet 14 on the movable base 10 to move to the specified position. Then the controller controls the second drive motor 20 to make the medicine pressing roller 21 start to rotate. The compressed medicine enters the medicine stripping mechanism through the surface friction of the medicine pressing roller 21. The medicine plate 28 is between the medicine pressing roller 21 and the compressed medicine tablet 14. The stripped medicine particles fall into the medicine particle collection box 1, and the discarded medicine plate 28 enters the empty medicine plate collection box 13 through the guide plate 15.

[0093] The staff can continuously put in the same type of medicine plates 28 to realize continuous medicine stripping. If different types of tablets are to be stripped, repositioning is required.
