Conveyor-type needle detector is generally used to detect hidden iron and needles in goods such as shoes, clothing, hats, textiles, food and pharmaceutical products.
[0003] In the prior art, a Chinese patent document with publication number CN219191435U proposes a needle detection and discharging device for a tablet press, which improves the structure of the discharging trough of the tablet press, and applies a miniaturized needle detector to the discharging trough, so that needle detection inspection can be directly performed while discharging. While significantly reducing the cost of needle detection inspection, the needle detection inspection can be ensured to be accurate and reliable. However, in actual application, there is still a problem that the tablet discharge speed of the tablet press outlet is relatively fast, and the discharging channel needs to be closed when removing unqualified tablets, so that the tablets are blocked in the discharging channel, resulting in tablet accumulation, which affects the normal use of the tablet press. Therefore, we disclose a needle detection and discharging component of a tablet press to meet the demand. Utility Model Content
