[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0024] Example 1
[0025] A multi-chip loading mechanism, see reference. Figure 1-4 It includes a medicine storage tray 1, a segmented turntable 3, a dust filter sieve 4, a rotating shaft 6, and a support column 7.
[0026] The medicine storage tray 1 is cylindrical with an open top, which is connected to the base 2. The medicine storage tray 1 can be made of stainless steel, which has good corrosion resistance and strength, ensuring that it will not wear down due to friction from the tablets during long-term use. The diameter of the medicine storage tray 1 can be designed to be 200mm to 300mm, and the height can be designed to be 150mm to 200mm, depending on actual needs. This size design can accommodate a sufficient number of tablets without taking up too much space.
[0027] The medicine storage tray 1 contains a segmented turntable 3 and a dust filter 4 arranged coaxially from top to bottom. Both the segmented turntable 3 and the dust filter 4 have a central hole 5 in the middle. The diameter of the central hole 5 can be designed to be 15mm to 20mm to facilitate the insertion of a rotating shaft 6. The rotating shaft 6 passes through the central hole 5, and its end is fixedly connected to the segmented turntable 3. The rotating shaft 6 can be made of stainless steel, with a diameter of 15mm, and its length can be designed to be 200mm to 250mm depending on the actual installation requirements. The connection between the rotating shaft 6 and the segmented turntable 3 can be a keyed connection or a threaded connection to ensure that relative slippage does not occur during rotation.
[0028] The dust filter sieve 4 is mounted on the medicine storage tray 1 via several support columns 7 at its bottom. The number of support columns 7 can be set to 3 to 6, evenly distributed around the dust filter sieve 4. The height of the support columns 7 can be designed to be 30mm to 50mm, and the diameter to be 8mm to 10mm. The support columns 7 can be made of stainless steel or engineering plastic, providing sufficient strength to support the dust filter sieve 4. The dust filter sieve 4 is provided with filter holes 8, the diameter of which is smaller than the diameter of the medicine tablets. The space between the dust filter sieve 4 and the medicine storage tray 1 is the dust collection chamber 9. The diameter of the filter holes 8 can be designed to be 0.5mm to 1mm. This design ensures that the medicine tablets will not fall into the dust collection chamber 9 through the filter holes 8, while the dust generated by the friction of the medicine tablets can smoothly pass through the filter holes 8 and enter the dust collection chamber 9. The height of the dust collection chamber 9 is the same as the height of the support columns 7, ranging from 30mm to 50mm. This height design ensures that the dust collection chamber 9 has sufficient space to accommodate the dust generated by the friction of the medicine tablets.
[0029] In operation, the tablet counting turntable 3 rotates under the drive of the motor and rotating shaft 6. As the tablets are counted, friction between the tablets and the turntable 3 generates dust. This dust is collected in the dust collection chamber 9 via the dust filter 4 below. The filter holes 8 on the dust filter 4 have a diameter smaller than the tablet diameter to prevent tablets from passing through. The motor can be a stepper motor or a servo motor, and the speed can be adjusted according to actual needs, generally set to 10 rpm to 30 rpm. This speed ensures that the tablets can smoothly enter the counting hole unit 10 without causing the tablets to fly out or be damaged due to excessive speed.
[0030] The tablet counting turntable 3 is arranged in a ring array with several groups of counting hole units 10, preferably three groups. Each counting hole unit 10 consists of a fixed number of tablet holes. Setting the number of counting hole units 10 to three groups can improve the counting efficiency without complicating the structure due to an excessive number. The number of tablet holes in each group of counting hole units 10 can be designed according to actual needs, generally set to 10 to 20, with the tablet holes arranged linearly or in a matrix. The diameter of the tablet holes is 1 to 1.5 times the diameter of the tablet, which ensures that only one tablet falls into the hole at a time and prevents the tablet from getting stuck in the hole. For example, if the diameter of the tablet is 8 mm, the diameter of the tablet holes can be designed to be 8 mm to 12 mm.
[0031] The dust filter sieve 4 is provided with a set of circular holes I11. The radius of the center of the circular holes I11 is the same as the radius of the center of the counting unit 10, and the diameter of the circular holes I11 is greater than the length of the counting unit 10. The diameter of the circular holes I11 can be designed to be 1.2 to 1.5 times the length of the counting unit 10. This design ensures that the tablets in the counting unit 10 can pass smoothly through the circular holes I11. For example, if the length of the counting unit 10 is 100 mm, the diameter of the circular holes I11 can be designed to be 120 mm to 150 mm.
[0032] The motor drives the slitting turntable 3 to rotate via the rotating shaft 6, thereby moving the tablets above the counting hole unit 10 and matching them with the tablet holes, thus ensuring that the tablets fill the tablet holes. When the counting hole unit 10 carries the tablets and rotates to the top of the round hole of the dust filter 4, the tablets fall below the round hole I11 of the dust filter 4.
[0033] The bottom of the medicine storage tray 1 is provided with a circular hole II12, located directly below the circular hole I11. A slide 13 connects to the packaging station below the circular hole II12. Tablets pass downwards through the circular holes I11 and II12 in sequence, and then slide 13 into the subsequent packaging station. The diameter of the circular hole II12 can be designed to be the same as or slightly smaller than that of the circular hole I11, generally set to 0.8 to 1 times the diameter of the circular hole I11. The slide 13 can be made of stainless steel with a smooth surface to ensure that the tablets can slide smoothly into the packaging station. The inclination angle of the slide 13 can be designed to be 30 to 45 degrees. This angle design ensures that the tablets slide smoothly without causing the tablets to slide down too quickly due to an excessively large angle.
[0034] Several positioning grooves 14 are provided around the circumference of the dust filter 4, and a corresponding number of positioning protrusions are provided on the side wall of the medicine storage tray 1. There are four positioning grooves 14 arranged in a circular array around the circumference of the dust filter 4; the number and installation position of the positioning protrusions correspond one-to-one with the positioning grooves 14. The width of the positioning groove 14 can be designed to be 5mm to 10mm, and the depth to be 3mm to 5mm; the width of the positioning protrusion matches the width of the positioning groove 14, and the height can be designed to be 2mm to 4mm, slightly less than the depth of the positioning groove 14. This design ensures that the positioning protrusions can be smoothly inserted into the positioning groove 14 without causing installation difficulties due to excessive size.
[0035] When in use, place the dust filter 4 on the support column 7. The positioning groove 14 and the positioning protrusion will limit the dust filter 4 to prevent it from rotating. The dust filter 4 is not fixed to the support base, which is convenient for disassembly and assembly. When the dust collection chamber 9 needs to be cleaned, simply take the dust filter 4 upwards to clean the medicine dust in the dust collection chamber 9.
[0036] The tablet counting turntable 3 is made of polytetrafluoroethylene (PTFE), which, compared to the bakelite material used in existing technologies, reduces friction between the tablets and the surface of the turntable 3, thus reducing tablet wear. PTFE has excellent wear resistance and self-lubricating properties, with a low coefficient of friction, effectively reducing tablet wear and dust generation during the counting process. Furthermore, PTFE also exhibits good corrosion resistance and high-temperature resistance, making it suitable for various tablet counting requirements.
[0037] The diameter of the tablet counting orifice in the counting unit 10 is 1-1.5 times the diameter of the tablet. This ensures that only one tablet falls into the orifice at a time, preventing tablets from getting stuck. For example, if the tablet diameter is 8mm, the orifice diameter can be designed to be 8mm to 12mm. This design ensures that the tablet can smoothly enter the orifice without causing multiple tablets to fall into one orifice simultaneously due to an excessively large orifice diameter.
[0038] The tablet counting mechanism of this embodiment, by setting a tablet-splitting turntable 3 and a dust filter sieve 4 in the drug storage tray 1, and forming a dust collection chamber 9 between the dust filter sieve 4 and the drug storage tray 1, can effectively collect the dust generated during the tablet counting process, preventing dust pollution to the environment and affecting the quality of the tablets. Simultaneously, by setting a positioning groove 14 and a positioning protrusion, the dust filter sieve 4 can be limited to prevent it from rotating during use, and it is also convenient to disassemble and clean the dust collection chamber 9. Furthermore, using a polytetrafluoroethylene (PTFE) tablet-splitting turntable 3 can reduce friction between the tablets and the surface of the turntable 3, reducing tablet wear.
[0039] In this embodiment, the medicine storage tray 1 and all components in the medicine storage tray 1 are inclined, which can improve the separation efficiency of the tablets.
[0040] It should be noted that each of the first embodiments is a type of multi-chip loading mechanism.
[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
