Description

Technical Field

[0001] The present invention relates to the technical field of medicine feeding, and more specifically to a quantitative feeding device for capsule medicine production. Background Art

[0002] In the production process of capsule medicine, quantitative feeding device plays a vital role. Among them, capsule positioning plate is one of the commonly used components, which is used to position the capsule for accurate feeding.

[0003] However, the existing capsule positioning disk has many defects in actual use. First, due to the inaccurate rotation positioning mechanism, the capsule is prone to deviate from the predetermined position during the capsule transmission and positioning process, causing the capsule medicine to scatter on the positioning disk. This not only destroys the cleanliness of the production environment, increases cleaning costs and time consumption, but also poses a serious challenge to the hygiene standards of drug production, and may cause hidden dangers to drug quality and safety.

[0004] The existing cleaning methods have obvious shortcomings. The operation process is relatively cumbersome and often requires stopping the machine and disassembling some devices for cleaning, which greatly reduces production efficiency and increases production costs. In addition, the cleaning process is technically difficult and requires professional personnel to operate. Ordinary workers are not competent for it, which further increases the human cost and management difficulty of the enterprise.

[0005] What is more serious is that if the scattered medicines are not cleaned for a long time, the medicines will gradually stack up and adhere to the positioning holes of the positioning plate. As the amount of adhesion increases, the capsule positioning will be inaccurate, resulting in deviations during feeding. This will directly affect the quantitative accuracy of the capsule medicines, resulting in uneven product quality and failure to meet strict pharmaceutical production quality standards. Once unqualified products enter the market, it will pose a threat to the health and safety of patients, and will also damage the company's reputation and market competitiveness. In view of this, we propose a quantitative feeding device for capsule medicine production. Summary of the invention

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention improves the structure of the existing quantitative feeding device for capsule medicine production, and conveys the capsule body to the capsule positioning disk through the capsule body conveying mechanism on the base, and then drives the capsule positioning disk to rotate accurately to the quantitative feeding hopper for filling by the intermittent rotating mechanism, and then rotates to the capsule cap conveying mechanism, and the capsule cap on the vibrating loading disk is conveyed to the capsule body by the capsule cap conveying mechanism, and then the capsule body and capsule cap are assembled by the pressing mechanism, and finally the finished product transportation mechanism realizes the discharge. Compared with the traditional positioning disk that is directly driven to rotate by a motor, the intermittent rotating mechanism of the present invention is accurate and not easy to deviate, which ensures the accuracy of quantitative feeding. The accurate intermittent rotation ensures the smooth connection of various processes, and the links from conveying, filling, capsule cap conveying and assembly to discharge can be completed in an orderly and efficient manner, reducing the rework, shutdown and adjustment caused by positioning deviation and other problems, thereby improving the overall production efficiency of capsule medicine, helping enterprises to increase production capacity and better meet market demand.

[0018] 2. In the present invention, the rotating arm is driven to rotate by a driving motor. Since the rotating arm and the rotating disk are rotatably connected, the rotating arm will not drive the rotating disk to rotate in the initial stage of rotation. At this time, one of the springs pushes the plug block to be inserted into the slot, so that the position of the rotating disk is fixed. When the rotating arm rotates to the plug block, the inclined surface A of the rotating arm squeezes the plug block and the spring inserted in the slot, so that the spring contracts and detaches from the slot. When the plug block detaches from the slot, the rotating disk is in an unfixed state, and the rotating arm pulls the tension spring, and the tension spring pulls the fixed column and the rotating disk to rotate. The rotation of the rotating disk drives the capsule positioning disk at the other end to rotate on the base. After the rotating disk rotates 45 degrees, the next spring squeezes the plug block to insert it into the slot, so that the rotating disk is fixed again. By analogy, the rotating disk drives the capsule positioning disk to rotate intermittently and rapidly at 45 degrees. Compared with the traditional motor directly driving the positioning disk, the positioning deviation problem caused by factors such as motor speed fluctuation and mechanical transmission error is effectively avoided, and the positioning accuracy of the capsule in each production process is greatly improved, thereby ensuring the accuracy of links such as quantitative feeding and capsule cap handling and assembly, laying a solid foundation for the production of high-quality capsule medicines.

[0019] 3. Due to the tension of the tension spring, the present invention makes the rotating disk drive the capsule positioning disk to rotate faster. Compared with the traditional driving method, the rotation switching time of the capsule positioning disk between each station is shortened, and the production efficiency of the entire capsule medicine production process is significantly improved. In large-scale production, this efficiency improvement can effectively increase the output per unit time, reduce production costs, and make enterprises more advantageous in market competition.

[0020] 4. In the present invention, a driving motor drives one of the gears to rotate, the gear meshes to drive the inner gear ring to rotate, the inner gear ring drives multiple gears to rotate synchronously, the other side of the gear meshes to drive the straight tooth groove to drive the cannula to move on the moving groove, when the bottom air hole of the cannula moves out of the outer ring seat, the bottom air hole is leaked, so that the gas pumped by the air pump through the air delivery hose is transmitted from the inside of the inner ring seat to the cannula, and sprayed downward from the bottom air hole of the cannula, such as Fig.15 As shown, it is used to purge the top of the plate body and the gap between the through hole and the positioning groove, solving the problem that the medicine is difficult to clean there; the present invention can effectively purge and clean the key parts of the positioning plate, namely the top surface of the plate body and the gap between the through hole and the positioning groove. Due to the complex structure of this part, it is difficult to completely remove the attached medicine by traditional cleaning methods, but the purge device of the present invention can act accurately there, ensuring that the medicine residue is effectively treated, maintaining the cleanliness of the positioning plate, avoiding problems such as inaccurate positioning and feeding deviation caused by medicine accumulation, and ensuring the accuracy and stability of capsule medicine production.

[0021] 5. In the present invention, when the motor drives one of the gears to rotate in the opposite direction, the gear meshes to drive the inner gear ring to rotate, and the inner gear ring drives multiple gears to rotate synchronously. The other side of the gear meshes to drive the straight tooth groove to drive the cannula to move on the movable groove. When the bottom air hole of the cannula moves into the outer ring seat, the bottom air hole is retracted so that the gas is retained in the inner cavity of the inner ring seat. When the motor reverses to retract the bottom air hole of the cannula, it can switch to the cooperation between the opening and closing block and the top shell, and guide the gas retained in the inner cavity of the inner ring seat to the jet pipe, and spray it out by the linear nozzle to purge the inner wall of the positioning groove. This flexible switching mechanism adapts to different parts and different cleaning needs, greatly improving the practicality and versatility of the cleaning device.

[0022] 6. The jet end of the centerline nozzle of the present invention is in a linear shape, which makes the ejected airflow shape long and narrow, and can cover a wider area than the traditional circular nozzle. When the inner wall of the positioning groove is purged, the purging area can be effectively expanded, the cleaning dead angle can be reduced, the cleaning efficiency and quality can be improved, and it can be ensured that the medicine in the positioning groove can be fully and thoroughly removed, which further improves the cleaning effect of the entire capsule positioning plate, helps to maintain the good operation state of the production equipment, and reduces equipment failures and product quality problems caused by residual medicine.

The blowing power unit 901 is arranged at the bottom end of the intermittent rotating mechanism 8, the lifting component 902 is arranged at a position where the intermittent rotating mechanism 8 is located at one end of the blowing power unit 901, the adjusting component 903 is movably inserted at a position of the intermittent rotating mechanism 8 close to the lifting component 902, the top blowing component 904 is movably inserted on the adjusting component 903, and the inner blowing component 905 is rotatably arranged on the adjusting component 903; The adjusting component 903 and the lifting component 902 cause the top blowing component 904 and the inner blowing component 905 to form an inner wall blowing state or a top surface blowing state.

[0026] The present invention improves the structure of the existing quantitative feeding device for capsule medicine production, and conveys the capsule body to the capsule positioning plate 7 through the capsule body conveying mechanism 2 on the base 1, and then drives the capsule positioning plate 7 to rotate accurately to the quantitative feeding hopper 3 for filling by the intermittent rotating mechanism 8, and then rotates to the capsule cap conveying mechanism 4, and the capsule cap on the vibrating loading plate 10 is conveyed to the capsule body by the capsule cap conveying mechanism 4, and then the capsule body and capsule cap are assembled by the pressing mechanism 5, and finally the finished product transportation mechanism 6 realizes the discharge. Compared with the traditional positioning plate that is directly driven to rotate by a motor, the intermittent rotating mechanism 8 of the present invention is accurate and not easy to deviate, which ensures the accuracy of quantitative feeding. The accurate intermittent rotation ensures the smooth connection of each process, and the links from conveying, filling, capsule cap conveying and assembly to discharge can be completed in an orderly and efficient manner, reducing the rework, shutdown and adjustment caused by positioning deviation and other problems, thereby improving the overall production efficiency of capsule medicine, helping enterprises to increase production capacity and better meet market demand.

[0027] In an embodiment of the present invention, the capsule positioning disk 7 includes a disk body 701, a disk bottom 702, a positioning groove 703 and a through hole 704. The disk bottom 702 is rotatably arranged at the exact center of the base 1, and the disk body 701 is fixedly arranged at the top of the disk bottom 702. The positioning grooves 703 are arranged in a circular shape with equal intervals on the outer wall of the disk body 701, and the through holes 704 are arranged in a circular shape with equal intervals on the disk bottom 702. The through holes 704 are located below the positioning grooves 703, and the diameter of the through holes 704 is smaller than the diameter of the positioning grooves 703. The positioning grooves 703 of the present invention are arranged on the outer wall of the disk body 701 and are connected to the outer wall. There are eight positioning grooves 703 and eight through holes 704. Since the diameter of the through holes 704 is smaller than the diameter of the positioning grooves 703, there is a gap between the through holes 704 and the positioning grooves 703, such as Fig.14 As shown, this gap is used to place the capsule body, but since this position is difficult to clean, the medicine purge mechanism 9 of the present invention is optimized for this position.

[0028] In an embodiment of the present invention, the intermittent rotating mechanism 8 includes an intermittent fast-rotation component 801, a hanging column 802, a hanging plate 803 and a motor 804. The intermittent fast-rotation component 801 is fixedly arranged at the bottom end of the base 1 and is located directly below the capsule positioning plate 7. The hanging column 802 is suspended at the bottom end of the base 1, and the hanging plate 803 is suspended at the bottom end of the hanging column 802. The motor 804 is arranged on the hanging plate 803, and the output end of the motor 804 is connected to the intermittent fast-rotation component 801. The end of the intermittent fast-rotation component 801 away from the motor 804 is connected to the capsule positioning plate 7.

[0029] In an embodiment of the present invention, the intermittent fast rotation component 801 includes a fixed shell 8011, a spring 8012, an insert 8013, a rotating disk 8014, a slot 8015, a fixed column 8016, a rotating arm 8017 and a tension spring 8018. The fixed shell 8011 is fixedly arranged at the bottom end of the base 1 at a position directly below the capsule positioning disk 7. The spring 8012 is connected to the inner wall of the fixed shell 8011 in an annular shape with equal spacing. The insert 8013 is connected to the end of the spring 8012 away from the fixed shell 8011. One end of the moving disk 8014 is rotatably disposed inside the fixed shell 8011, and the other end of the rotating disk 8014 is fixedly connected to the capsule positioning disk 7. The slot 8015 is opened on the outer wall of the rotating disk 8014, and the fixed column 8016 is fixedly disposed on the rotating disk 8014. One end of the rotating arm 8017 is rotatably disposed on the rotating disk 8014, and the other end of the rotating arm 8017 is connected to the output end of the motor 804. One end of the tension spring 8018 is connected to the fixed column 8016, and the other end of the tension spring 8018 is connected to the rotating arm 8017.

[0030] A movable groove 8021 is provided on the inner wall of the fixed shell 8011, and the spring 8012 and the plug block 8013 are arranged on the movable groove 8021. A slope A8022 is provided on the end of the plug block 8013 away from the spring 8012, and a slope B8023 is provided on one end of the rotating arm 8017. The slope A8022 is adapted to the slope B8023, and the slope A8022 is adapted to the slot 8015.

[0031] In the present invention, the rotating arm 8017 is driven to rotate by the driving motor 804. Since the rotating arm 8017 is rotatably connected to the rotating disk 8014, the rotating arm 8017 will not drive the rotating disk 8014 to rotate in the initial stage of rotation. At this time, one of the springs 8012 pushes the plug block 8013 to be inserted into the slot 8015, so that the position of the rotating disk 8014 is fixed. When the rotating arm 8017 rotates to the plug block 8013, the inclined surface A8022 of the rotating arm 8017 squeezes the plug block 8013 and the spring 8012 inserted into the slot 8015, so that the spring 8012 contracts and disengages from the slot 8015. When the plug block 8013 disengages from the slot 8015, the rotating disk 8014 is in an unfixed state, and the rotating arm 8017 pulls the tension spring 8018. The tension spring 80 18 pulls the fixed column 8016 and the rotating disk 8014 to rotate. The rotation of the rotating disk 8014 drives the capsule positioning disk 7 at the other end to rotate on the base 1. When the rotating disk 8014 rotates 45 degrees, the next spring 8012 squeezes the insert block 8013 to insert it into the slot 8015, so that the rotating disk 8014 is fixed again. Similarly, the rotating disk 8014 drives the capsule positioning disk 7 to rotate intermittently and rapidly at 45 degrees. Compared with the traditional motor directly driving the positioning disk, it effectively avoids the positioning deviation problem caused by factors such as motor speed fluctuation and mechanical transmission error, greatly improves the positioning accuracy of the capsule in each production process, thereby ensuring the accuracy of links such as quantitative feeding and capsule cap handling and assembly, and laying a solid foundation for the production of high-quality capsule medicines.

[0032] Due to the tension of the tension spring 8018, the rotating disk 8014 drives the capsule positioning disk 7 to rotate faster, which shortens the rotation switching time of the capsule positioning disk 7 between various stations compared to the traditional driving method, and significantly improves the production efficiency of the entire capsule medicine production process. In large-scale production, this efficiency improvement can effectively increase the output per unit time, reduce production costs, and make enterprises more competitive in the market.

The other side of the gear 9035 engages to drive the straight tooth groove 9042 to drive the cannula 9041 to move on the movable groove 9036. When the bottom air hole 9043 of the cannula 9041 moves into the outer ring seat 9032, the bottom air hole 9043 is retracted, so that the gas is retained in the inner cavity of the inner ring seat 9033. When the motor 9037 is reversed to retract the bottom air hole 9043 of the insertion tube 9041, the opening and closing hole A9054 on the opening and closing block 9052 cooperates with the opening and closing hole B9055 of the top shell 9051 to open, and the gas retained in the inner cavity of the inner ring seat 9033 is guided to the injection pipe 9056 and sprayed out by the line nozzle 9057 to purge the inner wall of the positioning groove 703; S3.2. If it is necessary to purge the top surface or the gap, the driving motor 9037 drives one of the gears 9035 to rotate, and the gear 9035 engages to drive the inner gear ring 9034 to rotate. The inner gear ring 9034 drives multiple gears 9035 to rotate synchronously. The other side of the gear 9035 engages to drive the straight tooth groove 9042 to drive the cannula 9041 to move on the movable groove 9036. When the bottom air hole 9043 of the cannula 9041 moves out of the outer ring seat 9032, the bottom air hole 9043 leaks out, so that the gas pumped by the air pump 9011 through the gas hose 9012 is transmitted from the inside of the inner ring seat 9033 to the cannula 9041, and is ejected downward from the bottom air hole 9043 of the cannula 9041 to purge the top of the disk body 701 and the gap between the through hole 704 and the positioning groove 703.
