Description

Technical Field

[0001] The invention relates to the technical field of traditional Chinese medicine diagnosis and treatment, and in particular to a prescription shredder. Background Art

[0002] A prescription refers to a medical document issued to patients by registered practicing physicians and practicing assistant physicians, referred to as physicians, during diagnosis and treatment, reviewed, dispensed, and checked by pharmaceutical professionals who have obtained the qualifications for pharmaceutical professional and technical positions, and used as a voucher for patients to take medication. Prescriptions include medical institution ward medication orders. Prescriptions are written documents for doctors to prescribe medication to patients, and are the basis for pharmacy personnel to dispense drugs, and carry legal, technical, and economic responsibilities.

[0003] In traditional Chinese medicine diagnosis and treatment, doctors are required to prescribe Chinese medicine for patients to get the medicine. When prescribing Chinese medicine, some waste paper will be generated, and some prescription information will remain in these waste papers. Most doctors directly discard them into the wastepaper basket without destructive treatment, which can easily cause the leakage of prescription information. If the patients pick them up and use them privately, it can easily cause medical accidents. Summary of the invention

[0044] Working principle: when in use, firstly, the exhaust fan 111 and the electric heating plate 211 are powered on. When the electric heating plate 211 is powered on, the paper pressing steel belt 205 is heated through the heat conducting plate 212, and then the driving motor 208 and the paper pushing motor 306 are started. The paper pushing motor 306 drives the lower pressing shaft 305 to rotate the toggle roller 307, and the prescription paper is placed on the support plate 116. The paper slides along the surface of the support plate 116 to the surface of the toggle roller 307, and then is introduced between the two toggle rollers 307 as the lower toggle roller 307 rotates, and then is introduced between the paper pressing steel belt 205. At this time, the driving motor 208 drives the driving shaft 203 to rotate through the worm gear reducer 209, and the driving shaft 203 drives the heating transmission shaft 202 to rotate through the first gear set 206. Then the heating transmission shaft 202 and the driving shaft 203 drive the paper pressing steel belt 205 to move through the steel belt wheel 204 on the surface. When the paper pressing steel belt 205 moves, it pulls the paper in, and then drives the paper to move slowly backward. When moving, the heat conduction of the paper pressing steel belt 205 and the baking of the heat conducting plate 212 gradually heat the paper, making the color of the paper gradually darker and the font gradually blurred, and then push it between the wheel groove roller 402 and the cutting wheel disc 403. At this time, the heating transmission shaft 202 drives the first synchronous belt 407 through the first transmission wheel 207, so that the second transmission wheel 405 rotates, and the second transmission wheel 405 drives the upper cutting shaft 401 to rotate, and then the upper cutting shaft 401 drives the lower cutting shaft 401 through the second gear set 404. The paper sheet 506 is rotated to rotate, thereby causing the groove roller 402 and the cutting wheel disc 403 to rotate. The rotating cutting wheel disc 403 cuts the arriving paper into filaments, and then the filamentary paper reaches the side of the paper pulling roller 506 as the paper pressing steel belt 205 is pushed forward. At this time, the cutting shaft 401 below drives the second synchronous belt 505 to rotate through the third transmission wheel 406, and the second synchronous belt 505 drives the paper pulling shaft 501 below to rotate through the fourth transmission wheel 503. The paper pulling shaft 501 below drives the upper paper pulling shaft 501 to rotate through the third gear set 502. The upper paper pulling shaft 501 drives the third synchronous belt 512 through the large transmission wheel 504, and then drives the fourth transmission wheel 503 to rotate. Since the outer diameter of the large transmission wheel 504 is larger than that of the fourth transmission wheel 503, so the rotation speed of the paper pulling shaft 501 is less than the rotation speed of the first paper tearing shaft 508. At the same time, the first paper tearing shaft 508 drives the second paper tearing shaft 509 to rotate through the fourth gear set 510, so that the rotation speed of the paper pulling roller 506 is less than the rotation speed of the paper tearing roller 513 and rotates. When the paper reaches the surface of the paper pulling roller 506, the paper pulling roller 506 pulls the filamentary paper to move. After being pulled by the paper pulling roller 506, the filamentary paper is pushed into the middle of the two paper tearing rollers 513, and the paper tearing roller 513 also pulls the filamentary paper. Since the rotation speed of the paper tearing roller 513 is greater than the rotation speed of the paper pulling roller 506, and because the worm gear reducer 209 cannot be driven in the reverse direction, the filamentary paper entering the paper tearing roller 513 is broken, and the broken paper strips fall into the receiving drawer 106 for storage.
