Description

Technical Field

[0001] This utility model relates to the field of blister packaging machines, specifically to a feeding mechanism for a blister packaging machine and a blister packaging machine. Background Technology

[0002] Blister packaging machines are specialized equipment for blister packaging of pharmaceuticals (tablets, capsules), food, health products and similar materials using aluminum (PTP) / plastic (PVC, PVDC) composite sealing. As upstream equipment, they are often combined with downstream equipment such as cartoning machines, checkweighers, and strapping machines to complete the entire production line from front to back.

[0003] Blister packaging machines are designed strictly according to the pharmaceutical industry's "GMP" standards. Their structure is precise and complex, mainly consisting of blister forming stations, unloading stations, visual inspection stations, heat sealing stations, batch number printing stations, and punching stations. The unloading station is the core station, composed of a vacuum feeder, unloading hopper, unloading vibratory feeder, and unloading plate (track). The proper functioning and efficiency of the unloading station directly affect product production efficiency and costs.

[0004] Chinese utility model patent CN206494170U discloses a feeding device for a high-speed blister packaging machine. This feeding device includes a feeding seat, multiple feeding tracks formed on the feeding seat, a hopper with a linear vibrator mounted at its lower end, and a disc with a rotary vibrator mounted at its lower end. The disc is located above the feeding seat, and its outlet connects to the multiple feeding tracks. However, in actual use, due to the different properties of the tablets themselves (hardness, brittleness, thickness, smoothness, etc.), uncoated tablets are relatively fragile during production, with insufficient surface smoothness or sharp edges, easily generating debris and powder through friction. Simultaneously, uncoated tablets are prone to moisture absorption or static electricity, adhering to the feeding tracks and outlet. This accumulation of debris and powder can cause blockages in the feeding tracks and outlet, requiring operators to stop the machine for troubleshooting.

[0005] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0006] To improve or solve the technical problem of debris and powder accumulation from pharmaceuticals in existing technologies, which leads to blockage of the feeding track and discharge port, this utility model provides a feeding mechanism for a blister packaging machine. The feeding mechanism includes: a feeding vibrating disc with a feeding area and a powder sieving area; a convex plate formed on the feeding area, and a discharge port formed on the convex plate; a plurality of sieve holes formed in the powder sieving area, and a storage box slidably fixed below the powder sieving area; and a feeding plate with a plurality of feeding tracks formed within it that communicate with the discharge port.

[0007] The feeding mechanism of this utility model for a blister packaging machine includes a feeding vibrating disc and a feeding plate. The feeding vibrating disc includes a feeding area and a powder screening area; the powder screening area forms several sieve holes, and a collection box is set below the powder screening area. When the feeding vibrating disc vibrates, the material moves circumferentially along the feeding vibrating disc. When passing through the powder screening area, the powder screening area can screen the debris and powder through the sieve holes, and the debris and powder fall into the collection box. The collection box is slidably fixedly connected to the feeding vibrating disc, which can facilitate the cleaning of debris and powder in the collection box. A convex plate is formed on the feeding area, and a discharge port is opened on the convex plate. The top surface of the convex plate is higher than the top surface of the feeding vibrating disc. When the feeding vibrating disc vibrates, the material moves circumferentially along the feeding vibrating disc. When passing through the convex plate, the material can climb up the convex plate under the action of vibration and be discharged from the discharge port. The debris and powder will be blocked to a certain extent at the convex plate, thereby preventing all the debris and powder from entering the discharge port. With the above-mentioned configuration, the feeding mechanism of this utility model for blister packaging machine can collect the debris and powder in the feeding vibratory plate and prevent the residual debris and powder from entering the feeding track and the discharge port, thus avoiding blockage of the feeding track and the discharge port.

[0008] Furthermore, it also includes a hopper arranged above the feeding vibrating plate; the screening area includes a first screening area and a second screening area, the first screening area is arranged behind the hopper along the flow direction of the material, and the second screening area is arranged in front of the feeding area along the flow direction of the material.

[0009] Furthermore, a track for mounting the storage box is provided below the feeding vibratory plate; the track includes a first guide rail and a second guide rail that are fixedly connected to the feeding vibratory plate, and a limiting groove is formed between the first guide rail and the feeding vibratory plate, and between the second guide rail and the feeding vibratory plate; limiting plates that match the limiting grooves are formed on both sides of the storage box.

[0010] Furthermore, a limiting bolt is provided on the first guide rail to abut against the limiting plate.

[0011] Furthermore, a handle is installed on the storage box.

[0012] Furthermore, the convex plate includes an uphill section and a horizontal section arranged sequentially along the flow direction of the material.

[0013] Furthermore, the convex plate also includes a downward slope section, and the discharge port is opened on the downward slope section; a discharge trough communicating with the discharge port is also opened on the horizontal section and the downward slope section.

[0014] To improve or solve the technical problem of drug debris and powder accumulation leading to blockage of the feeding track and discharge port in existing technologies, this utility model provides a blister packaging machine. The blister packaging machine includes a frame and a feeding mechanism as described above; the feeding vibrating disc and feeding plate of the feeding mechanism are mounted on the frame.

[0015] In summary, compared with the prior art, this utility model has the following beneficial effects:

[0016] (1) The sieving area forms several sieve holes, and a storage box is set below the sieving area; when the feeding vibrating plate vibrates, the material moves circumferentially along the feeding vibrating plate. When it passes through the sieving area, the sieving area can sieve the debris and powder through the sieve holes, and the debris and powder fall into the storage box; the storage box and the feeding vibrating plate form a sliding fixed connection, which can make it easier to clean the debris and powder in the storage box;

[0017] (2) A convex plate is formed on the feeding area, and a discharge port is opened on the convex plate. The top surface of the convex plate is higher than the top surface of the feeding vibrating plate. When the feeding vibrating plate vibrates, the material moves circumferentially along the feeding vibrating plate. When passing the convex plate, the material can climb up the convex plate under the action of vibration and be discharged from the discharge port. The debris and powder will be blocked to a certain extent at the convex plate, thereby preventing all the debris and powder from entering the discharge port. Attached Figure Description

Figure 2 This is another schematic diagram of an embodiment of the feeding mechanism of this utility model for a blister packaging machine. (See diagram below.) Figure 1 and Figure 2 As shown, in one or more embodiments, the feeding mechanism of the present invention for a blister packaging machine includes a hopper, a feeding vibrating plate 1, and a feeding plate.

[0027] See also Figure 1 and Figure 2 In one or more embodiments, the feeding vibratory plate 1 is generally disc-shaped, and a surrounding plate 11 is provided on the outer periphery of the feeding vibratory plate 1. A rotary vibrator 2 is provided below the feeding vibratory plate 1 to drive the feeding vibratory plate 1 to vibrate, thereby causing the material inside the feeding vibratory plate 1 to move circumferentially along the feeding vibratory plate 1. Based on Figure 1As shown, the material in the vibrating feeder 1 moves counterclockwise. Furthermore, the vibrating feeder 1 has a feeding area and a screening area 14. The screening area 14 includes a first screening area 141 and a second screening area 142. A hopper is arranged above the vibrating feeder 1. The feeding point of the hopper on the vibrating feeder 1 (…) Figure 1 The first screening zone 141, the second screening zone 142, and the feeding zone are arranged in a counter-clockwise direction (as shown by the dashed circle). The first screening zone 141 is located behind the hopper along the material flow direction, where powder and debris are easily generated when the material falls from the hopper to the feeding vibrating plate 1. The second screening zone 142 is located in front of the feeding zone along the material flow direction, where the material is screened again before entering the feeding zone. Specifically, both the first screening zone 141 and the second screening zone 142 are roughly fan-shaped, with several sieve holes to allow debris and powder to pass through while preventing material from falling.

[0028] Continue to participate Figure 1 and Figure 2 In one or more embodiments, a storage box 15 is provided below the first sieving area 141 and the second sieving area 142, and the storage box 15 is slidably fixedly connected to the feeding vibrating plate 1.

Specifically, the first guide rail 161 is generally stepped, its top abutting against the feeding vibrating plate 1 and connected to the feeding vibrating plate 1 by bolts; a limiting groove is formed between its stepped surface and the feeding vibrating plate 1 for limiting the storage box 15. The connection method of the second guide rail 162 and the first guide rail 161 is the same, and will not be described again here. Furthermore, a limiting bolt 163 is provided on the first guide rail 161, forming a threaded connection with the first guide rail 161. The shape of the storage box 15 matches that of the first powder screening area 141. Limiting plates 151 are provided on both sides of the storage box 15. The limiting plates 151 are slidably arranged in the limiting grooves, and the limiting bolts 163 abut against the limiting plates 151, which can press the limiting plates 151 tightly onto the feeding vibrating plate 1, thereby preventing the storage box 15 from falling off the feeding vibrating plate 1. Furthermore, a handle 152 is provided on the storage box 15 for pulling out the storage box 15.

[0029] See also Figure 1 and Figure 2In one or more embodiments, a protruding plate 17 is formed on the feeding area, and a discharge port 175 is provided on the protruding plate 17.
