Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, in particular to a medicine stripping machine with an automatic equal distribution and positioning connecting rod mechanism. Background Art

[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 contamination to the drugs.

[0003] Due to the differences between different drug packaging, the position of the compressed tablets needs to be adjusted before use. Existing drug separation devices are generally adjusted manually. When the demand for drugs is large, frequent manual adjustments not only waste time, but also are slow to adjust. In addition, it is difficult to accurately control the spacing between 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. Through the interaction between the provided rolling rubber wheel and the equalizing device, it realizes the automatic stripping of capsules or tablets. However, it is still difficult to adjust the spacing of the split pieces according to the spacing between tablets in the drug plate. Utility Model Content

[0046] The present invention relates to a pill stripping machine with an automatic equalizing positioning linkage mechanism. The pill stripping machine places a pill plate 28 in a pill feeding mechanism. An image sensor captures an image of the pill plate and transmits the data to a controller in the pill stripping machine. The controller processes the captured image, identifies the image, and calculates the spacing between each row of pills. The controller then issues a command to control a first drive motor, causing the compressed pills to automatically equalize and adjust their spacing. The image sensor captures images of the compressed pills in real time and transmits the data to the controller in the pill stripping machine. The controller processes the captured image and identifies the image. When the spacing between the compressed pills and the spacing between each row of pills is detected to be the same, the first drive motor stops, the second drive motor starts, and the pill pressing cylinder, driven by the second drive motor, begins rotating. The pill plate 28 is then fed between the compressed pill plate and the pressing cylinder, pressing the pills together and peeling the pills. Compared to existing technologies, the present invention has the advantages of automatically identifying the spacing between tablets in the pill plate 28 and automatically adjusting the position of the compressed pills, resulting in more accurate and faster pill stripping.
