Description

Technical Field

[0001] The utility model relates to the technical field of drug processing, in particular to a device for recycling waste materials after capsule production. Background Art

[0002] Capsule medicines refer to medicines that are made by putting medicines in hollow capsules. They are generally powders or granules that are irritating to the esophagus and gastric mucosa, or medicines that have a bad taste, are easy to evaporate, are easily decomposed by saliva in the mouth, and are easily inhaled into the trachea. Putting these medicines into capsules not only protects the medicinal properties of the medicines from being destroyed, but also protects the digestive organs and respiratory tract. In addition, some medicines need to be dissolved and absorbed in the intestines, and capsules are a kind of protection to prevent the medicines from being destroyed by stomach acid.

[0003] The manufacturing of capsules, filling of the capsules with drug powder and packaging of the finished products require multiple processes. Before the capsules become qualified finished products, they must undergo strict quality inspections. If the capsules are deformed during the manufacturing process, or if there are gaps in the capsules that are not tightly packed, these capsules will be unqualified, but the material of the capsule shell can be recycled. The unqualified capsules need to be disassembled and the drug powder and capsule shell separated and collected separately. However, existing capsule recycling and reuse devices have the problem of inconvenient waste collection. During the recycling process, the drugs in the capsules cannot be collected centrally, which reduces the cleanliness of the device, makes it inconvenient for operators to clean up the waste, and is not conducive to the use and development of the factory.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figure 1-4, including an outer shell 1, a screening barrel 4, which is installed inside the outer shell 1, and the two ends of the screening barrel 4 are retracted inwardly, so that the capsule can be concentrated in the middle position after entering the screening barrel 4. When the capsule moves to both sides of the screening barrel 4, the capsule slides toward the middle section of the screening barrel 4 through the inclination angles at both ends of the screening barrel 4, reducing the residual powder at the corners of the screening barrel 4 and improving the sanitation of the screening barrel 4; a movable cover 5 is installed at the inlet and outlet position of the screening barrel 4 through a rotating hinge; a buckle 6 is fixed to the surface of the movable cover 5 and is located on the side of the movable cover 5 away from the rotating hinge; a slot 7 is fixed to the surface of the screening barrel 4 and its position corresponds to the buckle 6. When the buckle 6 is close to the screening barrel 4, the capsule can be concentrated in the middle position. When the barrel 4 is divided, the buckle 6 can be inserted into the slot 7 for clamping and fixing, so that the screening barrel 4 and the movable cover 5 form a relatively closed space; the ratchet 1 8 is fixed to the side surface of the movable cover 5 close to the buckle 6; the pawl 1 9 is installed on one side of the screening barrel 4 through the support plate fixed to the inner wall of the shell 1, and the pawl 1 9 is close to the top of the screening barrel 4 and corresponds to the ratchet 1 8; the motor 10 is installed below the support plate, and the transmission end is fixed to the pawl 1 9, and the pawl 1 9 can be rotated by the motor 10; the ratchet 2 11 is fixed to the surface of the movable cover 5, and is in the same line as the ratchet 1 8, and the ratchet 2 11 is close to the side of the movable cover 5;The ratchet 2 12 is installed on the side of the screening barrel 4 away from the ratchet 1 9. The ratchet 2 12 has the same structure as the ratchet 1 9 and is also connected to a motor 10 at the bottom. The cut capsule is placed inside the screening barrel 4 and the screening barrel 4 is rotated to separate the capsule shell and the powder. The separated powder falls from the mesh of the screening barrel 4. After the capsule shell and the powder are separated, the capsule shell waste inside the screening barrel 4 needs to be poured out from the inside of the screening barrel 4. First, the ratchet 9 is rotated by the motor 10 so that the ratchet 9 is facing the ratchet 8. When the screening barrel 4 rotates toward the direction of the pawl 9 (counterclockwise), the pawl 9 clamps the ratchet 8. After the screening barrel 4 rotates to a certain angle, the buckle 6 breaks free from the slot 7, so that the movable cover 5 is opened. Then the pawl 9 is rotated again to stagger the pawl 9 and the ratchet 8, so that the movable cover 5 can rotate and move with the ratchet 8. When the screening barrel 4 continues to rotate toward the direction of the pawl 9 (counterclockwise), the side of the movable cover 5 close to the buckle 6 naturally rotates and falls, so that the inlet and outlet of the screening barrel 4 are exposed. When the inlet and outlet are facing downward, the inside of the screening barrel 4 is The capsule shell of the lower part falls out from the inside of the screening barrel 4, and the screening barrel 4 continues to rotate. The movable cover 5 always remains in the open state when the screening barrel 4 rotates, until the inlet and outlet of the screening barrel 4 are aligned with the feed port 2 again, and the feed port 2 pours the capsule into the inside of the screening barrel 4 again through the inlet and outlet opened by the screening barrel 4, and then the screening barrel 4 is rotated in the direction of the pawl 2 12 (clockwise), and the pawl 2 12 is rotated by the motor 10 so that the end of the pawl 2 12 corresponds to the ratchet 2 11. When the feed port 2 rotates, the pawl 2 12 pushes the movable cover 5 to the card The latch 6 is pushed in the direction of the ratchet 11. When the second ratchet 11 contacts the second pawl 12, the pressure of the second pawl 12 on the second ratchet 11 increases, causing the latch 6 to reengage the engagement slot 7, thereby sealing the screening barrel 4 and preventing the capsule shells inside the screening barrel 4 from falling out of the inlet and outlet when the screening barrel 4 rotates. When the movable cover 5 is closed, the second pawl 12 is rotated toward the side of the screening barrel 4 by the motor 10, staggering the second pawl 12 and the second ratchet 11. This reduces the contact between the second pawl 12 and the second ratchet 11 when the screening barrel 4 rotates, thereby reducing noise during production.

[0031] A feed port 2 is provided at the top of the outer shell 1 at a position corresponding to the screening barrel 4, and a guide plate 3 is installed below the feed port 2, and the guide plate 3 and the feed port 2 are movably installed, and a movable support rod is installed on one side of the guide plate 3, and an adjustment groove is provided on the outer wall of the feed port 2 at a position corresponding to the movable support rod, and a support plate is fixed on one side of the top of the adjustment groove, and the height of the guide plate 3 can be adjusted by overlapping the support rod and the support plate. When the feed port 2 moves downward, the guide plate 3 is closer to the inlet and outlet of the screening barrel 4. When feeding the screening barrel 4 through the feed port 2, the guide plate 3 can make the waste material more accurately delivered to the inside of the screening barrel 4, thereby reducing the loss of waste material. When the movable cover 5 is closed, the guide plate 3 needs to be adjusted upward to avoid collision between the movable cover 5 and the guide plate 3.

[0032] One side of the screening barrel 4 is fixed to the connecting frame 13, and the side of the screening barrel 4 away from the connecting frame 13 is installed in a ring fixed on the inner wall of the outer shell 1. The side of the connecting frame 13 away from the screening barrel 4 is installed with a motor 2 14, and the motor 2 14 is located on the outside of the outer shell 1 to simulate the rotation of the connecting frame 13 driven by the motor 2 14. The connecting frame 13 synchronously drives the screening barrel 4 to rotate, thereby separating the capsule shell and the medicine powder inside the screening barrel 4.

[0033] A fixing plate 15 is installed inside the screening barrel 4 on the side close to the connecting frame 13. A limit rod is fixed to the fixing plate 15 corresponding to the midline position of the screening barrel 4. A movable hole is provided on the side wall of the screening barrel 4 corresponding to the position of the limit rod. A stirring blade 16 is fixed on the side of the fixing plate 15 away from the connecting frame 13. When the screening barrel 4 rotates, the fixing plate 15 remains stationary and the stirring blade 16 is stationary together with the fixing plate 15. When the capsules inside the screening barrel 4 roll together with the screening barrel 4, the stirring blade 16 intercepts the rolling capsules, so that the capsules are more thoroughly disrupted. When the stirring blade 16 intercepts the capsules, some capsules will pass through the surface of the stirring blade 16, increasing the height difference of the capsules and improving the vibration of the capsules, thereby improving the separation effect of the medicine powder and the capsule shell.

[0034] A screen 17 is fixed below the screening barrel 4, tilted toward the direction of the first pawl 9. A discharge port is provided at one end of the bottom of the housing 1 corresponding to the screen 17. A guide plate 2 18 is fixed below the screen 17, tilted toward the direction of the second pawl 12. A discharge port is provided at one end of the bottom of the housing 1 corresponding to the guide plate 2 18. When the powder inside the screening barrel 4 falls through the mesh of the screening barrel 4, it first passes through the screen 17, then falls onto the surface of the guide plate 2 18 through the mesh of the screen 17. The collected powder is then guided out of the housing 1 by the guide plate 2 18. After the capsule shells inside the screening barrel 4 are poured out, they fall onto the surface of the screen 17 and roll toward the outside of the housing 1 along the slope of the screen 17, thereby being guided out of the housing 1, leaving space for the powder to be screened later.

[0035] Working principle: pour the cut capsules into the screening barrel 4 from above the feed port 2, and rotate the screening barrel 4 clockwise to make the pawl 2 12 close the movable cover 5 and the screening barrel 4, and press the ratchet 2 11 through the pawl 2 12 to make the buckle 6 stuck in the card slot 7, so that the screening barrel 4 is completely fixed. After the pawl 2 12 closes the movable cover 5, the pawl 2 12 is rotated to make the position of the pawl 2 12 and the ratchet 1 8 staggered, thereby avoiding the contact between the ratchet 2 11 and the ratchet 2 12 when the screening barrel 4 rotates, thereby reducing the generation of noise. When the screening barrel 4 rotates, the capsules inside begin to roll, so that the powder is separated from the capsule shell, and the powder falls to the bottom of the screening barrel 4 after sedimentation, and then falls through the mesh of the screening barrel 4. The fallen powder passes through the screen 17 and falls onto the surface of the guide plate 2 18, and passes through the guide plate The powder is sent out of the shell 1 by the guide of plate 2 18. After the screening barrel 4 completes the separation of the medicine powder and the capsule shell, only the capsule shell remains in the screening barrel 4. The ratchet 19 is rotated by the motor 10 so that the ratchet 19 corresponds to the ratchet 18, and the screening barrel 4 is rotated counterclockwise. When the ratchet 18 contacts the ratchet 19, the ratchet 19 clamps the ratchet 18. When the screening barrel 4 continues to rotate, the buckle 6 breaks free from the inside of the slot 7, so that the movable cover 5 is opened. After the movable cover 5 is opened, the ratchet 9 is rotated so that the ratchet 9 is misaligned with the ratchet 8. The movable cover 5 can move together with the screening barrel 4. When the inlet and outlet of the screening barrel 4 move downward, the capsule shell inside the screening barrel 4 falls from the inlet and outlet, falls on the surface of the screen 17, slides through the slope of the screen 17, and moves to the outside of the shell 1 for collection.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
