Description

Technical Field

[0001] The invention relates to the technical field of capsule polishing equipment, in particular to a vertical capsule polishing machine. Background Art

[0002] Capsules are protective shells for drugs. Drugs in capsules are usually powders or granules that are irritating to the esophagus and gastric mucosa, or have a bad taste, are easy to volatilize, are easily decomposed by saliva in the mouth, and are easily inhaled into the trachea. Putting these drugs into capsules not only protects the drug properties from being destroyed, but also protects the digestive organs and respiratory tract. The capsule polisher is a special polishing equipment for capsules. After the drug is placed in the polishing barrel, the capsule is polished by powder absorption to improve the surface finish. The existing capsule polishers cannot accurately control the amount of powder provided to the polishing barrel, and most of them are supplied in approximate amounts, which may cause waste due to excessive amounts or affect the polishing effect due to insufficient amounts.

The driver 104 is a servo motor, which is used to drive the driving shaft 201 to rotate, thereby driving the polishing barrel 205 to rotate as a whole. The rotating shaft 202 is installed in the bearing seat 105.

[0037] A powder supply mechanism 7 is provided on the upper part of the frame 1. The powder supply mechanism 7 includes a base 701 installed on the frame 1. A feed pipe 702 is provided on the upper part of the base 701. A pipe cover 724 is provided on the upper part of the feed pipe 702. A powder inlet 725 is provided in the middle of the pipe cover 724. A feed block 705 is provided at the bottom of the feed pipe 702. A feed notch 717 is provided on the feed block 705. A central axis 707 is rotatably provided in the middle of the feed block 705. A rotating disk 706 is connected to the upper end of the central axis 707. The bottom of the rotating disk 706 is provided to fit the top of the feed block 705. The rotating disk 706 is provided with a plurality of powder loading holes 720, the distance from the center of the powder loading hole 720 to the center of the rotating disk 706 is the same as the distance from the center of the material discharge notch 717 to the center of the rotating disk 706, the size of the powder loading hole 720 is not larger than the size of the material discharge notch 717, a positioning tube 714 is provided in the feed tube 702 at a position above the material discharge notch 717, the top of the positioning tube 714 is connected to the bottom of the tube cover 724, and a blocking block 715 is provided at the bottom of the positioning tube 714, and a part of the blocking block 715 The first spring 716 is arranged inside the positioning tube 714, one end of the first spring 716 abuts against the bottom of the tube cover 724, and the other end abuts against the top of the blocking block 715. The size of the bottom of the blocking block 715 is larger than the size of the powder filling hole 720. The lower end of the central axis 707 passes through the base 701 and is connected to a synchronous wheel 709. A powder supply motor 718 is provided on the base 701, and a motor cover 703 is provided outside the powder supply motor 718. The powder supply motor 718 is driven and connected to a driving flywheel 704, and the driving flywheel 704 and the synchronous wheel 709 are connected. It is connected to a synchronous belt 710, and a powder supply tee 719 is provided under the base 701. The upper part of the vertical section of the powder supply tee 719 is inserted into the discharge notch 717 from bottom to top. One end of the horizontal section of the powder supply tee 719 is connected to the compressor, and the other end is connected to a powder supply pipe 721. The end of the powder supply pipe 721 away from the powder supply tee 719 is connected to the powder inlet hole 203. The compressor generates negative pressure by working, and the powder that enters the powder supply tee 719 through the discharge notch 717 is transported to the polishing barrel 205 through the powder supply pipe 721 and the powder inlet hole 203.

[0038] Polishing powder enters the feeding tube 702 from the powder inlet 725 in the middle of the tube cover 724, falls on the rotating disk 706, and is filled into the powder loading hole 720. The air supply motor 718 drives the flywheel 704 to rotate, and the flywheel 704 drives the synchronous wheel 709 to rotate through the synchronous belt 710, and the synchronous wheel 709 drives the rotating disk 706 to rotate through the central shaft 707. When the powder loading hole 720 on the rotating disk 706 rotates to the blocking block 715, the blocking block 715 presses against the rotating disk 706 under the action of the first spring 716, thereby blocking the powder on the rotating disk 706, and only the powder in the powder loading hole 720 can reach the unloading gap 717, ensuring that the powder supply amount each time is the amount filled in one powder loading hole 720. The positioning tube 1 714 and the material stopper 715 are both hollow, and the tube cover 724 has a through hole corresponding to the top of the positioning tube 1 714, so that the material discharge gap 717 is connected to the outside. The compressor is operated to form a negative pressure in the powder supply pipeline 721, and the powder reaching the material discharge gap 717 is sucked into the powder supply tee 719, and then moves along the powder supply pipeline 721 and enters the polishing barrel 205 through the powder inlet hole 203. When the powder filling through hole 720 supplied with powder is rotated out from the material stopper 715, the powder on the rotating disk 706 will fall into the powder filling through hole 720 to fill it up.

[0039] Preferably, the lower end of the central axis 707 is connected to a second detection disk 711, and a second detection notch 712 is provided on the second detection disk 711. The lower part of the base 701 is provided with a second infrared monitor 713 that matches the second detection notch 712. The number of the second detection notches 712 is the same as the number of the powder-loading through holes 720, and the positions are arranged in a one-to-one correspondence. By detecting the second detection notches 712 with the second infrared monitor 713, the number of the powder-loading through holes 720 passing through the lower powder notch 717 can be obtained, and this number can be multiplied by the powder loading amount of the powder-loading through holes 720 to obtain the total supply of powder.

[0040] Preferably, one end of the driving shaft 201 away from the polishing barrel 205 passes through the driver 104 and is connected to the first detection disk 106, on which a plurality of first detection notches 107 are provided, and the driver 104 is provided with a first infrared detector 108 that matches the first detection notches 107. The first infrared detector 108 detects the passage of the first detection notches 107 on the first detection disk 106, and obtains the rotation of the driving shaft 201, thereby obtaining the number of rotations of the polishing barrel 205.

[0041] Preferably, a dispersion block 708 is provided in the middle position of the upper part of the rotating disk 706. The dispersion block 708 is a truncated cone and the diameter of the upper end is smaller than the diameter of the lower end. After the powder entering the feeding tube 702 from the powder inlet 725 falls on the dispersion block 708, it slides down along the side of the dispersion block 708 and is scattered on the rotating disk 706, thereby preventing the powder from accumulating in the middle of the rotating disk 706 and failing to fill the powder filling hole 720.

[0042] Preferably, a plurality of observation ports 723 are provided on the feed tube 702, and a transparent tube 722 is provided inside the feed tube 702, and the transparent tube 722 covers the observation ports 723.

[0044] When feeding or discharging, the electric push rod 807 at the upper and lower ends of the corresponding polishing barrel 205 runs, and the electric push rod 807 abuts against the abutment rod to push the stop rod 802 to move leftward, and the stop rod 802 drives the moving cover 803 to move leftward so that the positioning tube 2 804 is aligned with the openings at the upper and lower ends of the polishing barrel 205. At this time, the capsule enters from the opening at the upper end of the polishing barrel 205 for loading or the polishing barrel 205 is discharged from the opening at the lower end for unloading. The size of the positioning tube 2 804 is not larger than the size of the openings at the upper and lower ends of the polishing barrel 205, ensuring that the capsule will not fall from the gap during the feeding process.

[0045] When sealing, the electric push rod 807 retracts, and the gear rod 802 moves to the right and resets under the action of the second spring 806, so that the positioning tube 804 is staggered with the openings at the upper and lower ends of the polishing barrel 205. At the same time, the lower end of the movable cover 803 fits the openings at the upper and lower ends of the polishing barrel 205 to form a seal, ensuring that the internal capsule will not fall out when the polishing barrel 205 rotates.

The capsules are conveyed through the hopper outlet 609. The size of the hopper outlet 609 is set according to the required capsule discharge speed. The front and rear parts of the hopper 606 close to the frame 1 are connected with ribs 607. The height of the ribs 607 is slightly higher than the height of the hopper outlet 609, thereby preventing the capsules from falling from the front and rear sides of the conveyor belt 605. The other end of the ribs 607 is connected with a discharge guide plate 608. The discharge guide plate 608 is located in the lower middle position of the right end of the conveyor belt 605.
