Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical equipment, in particular to a rejecting device of an osmotic pump tablet punching machine. Background Art

[0002] Osmotic pump tablets are a type of sustained-release tablet preparation with a semipermeable membrane on the surface. Usually, micropores are punched on the semipermeable membrane. After the preparation is taken, the water in the liquid can pass through the semipermeable membrane into the inner core of the preparation. The propellant in the inner core of the preparation absorbs the water and begins to expand to produce a pumping effect - pressure. At the same time, the preparation begins to dissolve. The increase in pressure forces the dissolved drug to slowly release through the micropores punched on the semipermeable membrane and diffuse into the human body, achieving the purpose of stable and controlled release of the drug. Therefore, the release micropores on the semipermeable membrane are crucial to the release quality of osmotic pump preparations.

[0003] Carbon dioxide lasers are now widely used for laser drilling of osmotic pump tablets. The characteristics of carbon dioxide lasers can be used to drill holes in the coating layer of controlled-release preparations. It has high processing efficiency, processing accuracy and stability, ensuring the consistency of drug processing.

[0004] After laser drilling of osmotic pump tablets, post-processes such as inspection and rejection are required to ensure production quality. At present, air blowing is often used to reject unqualified tablets. However, the existing air blowing rejection method has disadvantages: when multiple tablets are rejected at the same time, adjacent qualified tablets are easily rejected, which affects the qualified rate. If only one tablet is rejected at a time, the efficiency is low, which affects the overall production efficiency of the punching machine. Utility Model Content

[0028] like Figure 1-4As shown, a rejection device of an osmotic pump tablet punching machine includes a carrier 1, a blowing assembly 2 and a material channel box 3, wherein the carrier 1 is provided with a plurality of material troughs 11 for filling tablets arranged in an array, the blowing assembly 2 is arranged below the carrier 1, and includes a plurality of independently controlled blowing needles 21, and the blowing port of each of the blowing needles 21 is arranged one-to-one corresponding to the material trough 11 on the carrier 1; the material channel box 3 is arranged above the carrier 1, and is provided with a plurality of material channels 31 arranged one-to-one corresponding to the blowing needles 21, one end of each of the material channels 31 is an inlet covering directly above a material trough 11, and the other end is an outlet connected to a defective bin (not shown in the figure), and the correspondingly arranged inlets of the material channels 31, the material troughs 11, and the blowing ports of the blowing needles 21 are arranged on the same straight line from top to bottom. That is, the blowing needle 21, the material trough 11, and the material channel 31 are arranged in one-to-one correspondence. Through the precise control of the control system point, it is ensured that the blowing needle at the position of the unqualified product blows air, and the blowing needle at the position of the qualified product does not blow air, and the material channel inlet covers the top of the corresponding material trough. Multiple products can be rejected at one time, and the influence of the blowing needle on the adjacent ones when blowing can be avoided, thereby ensuring the rejection efficiency and the rejection effect.

[0029] like Figure 1-4 As shown, the material channel box 3 includes a material channel body 32 and a cover plate 33. The material channel 31 is arranged on the material channel body 32 and is an arc-shaped groove. Multiple material channels 31 are arranged concentrically along the center of the material channel body 32, corresponding to the material troughs 11 arranged in an array. The arc-shaped material channel 31 can facilitate the passage of tablets. The cover plate 33 covers the outer side of the material channel body 32 and is used to close the arc-shaped opening of the groove, which can facilitate the processing of the material channel box 3.

[0030] like Figure 4 As shown, both sides of the material channel body 32 along the conveying direction are provided with material channels 31, and the material channels 31 on both sides are arranged in a staggered manner. Correspondingly, the air blowing needles 21 are also arranged in two rows, which are arranged in a staggered manner, and the sum of the number of material channels 31 on both sides corresponds to a row of material troughs 11 along the conveying direction on the carrier 1. This arrangement can facilitate the arrangement of the material channels 31, and the arrangement of the material channels makes each air blowing and rejecting channel independent and does not affect each other.

[0031] like Figure 3-4 As shown, an arc-shaped boss 34 is provided between adjacent material channels 31 and is arranged concentrically with the material channels 31, and one end of the arc-shaped boss 34 near the inlet of the material channel 31 covers the top of a material trough 11 located between two adjacent material channels 31. The gap between the bottom surface of the material channel box 3 and the top surface of the carrier 1 is matched, and this gap is small, so that the carrier 1 can pass smoothly between the material channel box 3 and the blowing needle 21 and the tablets will not leak out; through this arrangement, the tablets in the material trough 11 covered by the end of the arc-shaped boss 34 will not be blown out when blowing, which can further avoid the influence of blowing on the adjacent material troughs and ensure the rejection effect.

By adjusting the blowing flow rate, the best rejection effect can be guaranteed.

[0034] In the above structure, if Figure 3 As shown, the blowing assembly 2 further includes an adjustment seat 23 and a connecting rod 24. The connecting rod 24 is fixedly connected to the blowing seat 22. One end of the connecting rod 24 is inserted into the adjustment seat 23 and is rotatably connected to the adjustment seat 23. The adjustment seat 23 is also provided with a limiter for limiting the rotation position of the connecting rod 24. By adjusting the angle of the connecting rod 24, the angle of the blowing seat 22 can be adjusted, so as to correspond to the position of the carrier 1, so that the blowing port is directly facing the material trough 11, and the best blowing effect is guaranteed.

[0035] In addition, if Figure 1-2 As shown, the outlet end of the material channel box 3 is provided with a guide hopper 5, the outlet end of the material channel box 3 is fixed on the top of the guide hopper 5, and the guide hopper 5 is a bucket body with a large upper part and a small lower part, and a plurality of inclined guide plates are provided at the lower end. The setting of the guide hopper 5 allows the tablets to slide into the defective bin more smoothly.

[0036] Example 3

[0037] Based on the structure of Example 2, Figure 5 As shown, the carrier 1 is arranged on a chain plate type circular conveyor chain 4, which can circulate along the circular conveyor profile. The circular conveyor chain 4 is tilted and tilted upward along the conveying direction; the tilted circular conveyor chain 4 can ensure the filling rate of the carrier and improve the punching accuracy.
