Technical Field
[0001] This utility model relates to a blister packaging machine, specifically to a pill replenishment device for a blister packaging machine. Background Technology
[0002] Blister packaging machines are pharmaceutical packaging equipment used to package pills in blister packs. During the blister packaging process, pills are added to the blister pack's openings using a pill feeding device. However, because the blister pack moves at a high speed during normal operation, some openings may not contain pills. This results in entire blister packs of pills being rejected after packaging, leading to drug waste and increased production costs. Currently, replenishing the pills after initial feeding is typically achieved by installing multiple brushes on a turntable, with the turntable and brushes rotating continuously during operation. This method results in a large overall structure. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a blister packaging machine pill replenishment device for missing pills after feeding. The device has a simple and compact structure and occupies little space.
[0004] This utility model is implemented through the following technical solution:
[0005] A blister pack pill replenishment device is characterized by: including a feeding trough plate, which is fixedly installed; multiple sets of vertical feeding troughs are arranged side by side on the front of the feeding trough plate, each set having multiple vertical feeding troughs; the upper end face of the feeding trough plate has an inclined design; the upper half of the feeding trough plate is located inside the pill storage hopper; the pill storage hopper is driven by a motor to move up and down.
[0006] Each feeding trough has a corresponding locking pill near the bottom. The locking pill can move in and out of the feeding channel of the feeding trough. The locking pill is connected to the locking trough block, which is movable.
[0007] A strip plate is provided on the back of the feed trough plate, and a positioning notch is provided on the strip plate. The locking drug trough block is fixedly connected to the strip plate. A locking drug pull handle is provided between the strip plate and the feed trough plate. The locking drug pull handle can be pulled left and right. A wedge is provided at the position of the locking drug pull handle corresponding to the positioning notch. The left and right pulling of the locking drug pull handle is guided by the guide groove provided by the locking drug fixing seat. The locking drug fixing seat is fixedly connected to the feed trough plate. A spring is provided on the back of the strip plate to abut against the locking drug fixing seat.
[0008] The pill storage hopper is fixedly connected to a lifting plate, which is connected to an eccentric turntable via a connecting rod. The eccentric turntable is mounted on the output shaft of the motor, and the vertical movement of the lifting plate is guided by a vertical guide rail.
[0009] A dust collection hopper is installed on the outside of the pill storage hopper, and a dust discharge hole is provided in the pill storage hopper.
[0010] By adopting the above technical solution, this utility model enables the pills in the pill storage hopper to smoothly enter the feeding trough through the rapid up-and-down reciprocating motion of the upper half of the feeding trough plate, and then be fed out through the feeding trough and added to the bubble eye of the blister pack that is missing pills; and as shown in the attached instruction manual... Figure 5 It is evident that the structure of this utility model is similar in appearance to the pill feeding device of the blister packaging machine, and the structure is simple and compact with a small space occupation.

[0018] like Figure 1-5As shown, the blister pack pill replenishment device of this utility model includes a feeding trough plate 3, which is fixedly connected to a housing base 24 via a horizontal plate 25. The housing base 24 is fixedly installed on a blister pack conveying platform 22. Three sets of five vertical feeding troughs 6 are arranged side by side on the front of the feeding trough plate 3. A cover plate 4 is fixedly connected to the front of the feeding trough plate 3. The upper end surface of the feeding trough plate 3 has an inclined surface 17 to facilitate the entry of pills into the feeding troughs 6. Each feeding trough 6 has a corresponding locking piece 19 near the lower part. The locking piece 19 can move in and out of the feeding channel of the feeding trough 6. The locking piece 19 is connected to... On the drug-locking trough block 18, a strip plate 15 is provided on the back of the feed trough plate 3. A positioning notch 14 is provided on the strip plate 15. The drug-locking trough block 18 is fixedly connected to the strip plate 15. A drug-locking pull handle 5 is provided between the strip plate 15 and the feed trough plate 3. The drug-locking pull handle 5 can be pulled left and right. A wedge block 13 is provided at the position corresponding to the positioning notch 14 of the drug-locking pull handle 5. The left and right pulling of the drug-locking pull handle 5 is guided by the guide groove provided by the drug-locking fixing seat 16. The drug-locking fixing seat 16 is fixedly connected to the feed trough plate 3. A spring 20 is provided on the back of the strip plate 15 to abut against the drug-locking fixing seat 16. The upper half of the feed trough plate 3 is located inside the pill storage hopper 1. The pill storage hopper 1 is driven by the motor 7 to move up and down. The motor 7 is fixedly installed on the back of the housing base 24. The pill storage hopper 1 is fixedly connected to the lifting plate 10. The lifting plate 10 is connected to the eccentric turntable 8 through the connecting rod 9. The eccentric turntable 8 is installed on the output shaft of the motor 7. The up and down movement of the lifting plate 10 is guided by the vertical guide rail 11. A dust receiving hopper 12 is provided on the outside of the pill storage hopper 1. The pill storage hopper 1 is provided with a dust discharge hole 2.
[0019] The working process of this utility model is as follows: The blister pack 23 is pulled and conveyed by the blister pack conveyor platform 22. The pill feeding device 21 adds pills into the blister pack 23. At the blister pack pill replenishment device of this utility model, the pill storage hopper 1 is driven by the motor 7 to make rapid up-and-down reciprocating motion. The pills in the pill storage hopper 1 enter the feeding trough 6 and reach the feeding trough outlet through the feeding trough 6. If a blister pack with a missing pill passes by, the pill in the corresponding feeding trough 6 will be sent out and added to the blister pack with a missing pill, completing the replenishment action. When the machine is stopped or the replenishment action is not needed, the locking handle 5 is pulled by hand. The wedge 13 is positioned in the positioning notch 14. Under the action of the spring 20, the strip plate 15 moves forward, driving the locking pill block 18 and locking pill tablet 19 forward. The locking pill tablet 19 enters the feeding channel of the feeding trough 6, blocking the pills in the feeding trough 6 from continuing to pass through. When a feeding action is needed, the locking pill pull handle 5 is pulled in the opposite direction, causing the wedge 13 to leave the positioning notch 14. The wedge 13 then presses against the strip plate 15 and compresses the spring 20. The strip plate 15 moves backward, driving the locking pill block 18 and locking pill tablet 19 backward. The locking pill tablet 19 leaves the feeding channel of the feeding trough 6, allowing the pills in the feeding trough 6 to pass through smoothly.
