Embodiment

[0012] Such as figure 1 , shown in Fig. 2, Fig. 3, a kind of new-type disposable injection needle loading machine described in this embodiment comprises a needle taking plate 3, a needle groove 4 and a needle falling groove 5, and an electromagnetic needle is provided on the needle taking plate 3. Iron pull-in device 7, described electromagnet pull-in device 7 is mainly made up of electromagnet bar 1, electromagnetic coil 8 and capacitor 10, and capacitor 10 is connected in parallel with electromagnetic coil 8 through positive and negative conversion switch 9. When the needle-taking plate 3 tops a needle tube 2 from the needle groove 4, the electromagnet strip 1 is energized to generate a magnetic field to immediately attract the needle tube 2, and then the electromagnet strip 1 is pushed to the needle drop groove 5 by the cylinder 6, thus When disconnecting the power supply and utilizing the reverse discharge of the capacitor 7 to demagnetize the needle tube 2, the needle tub...

The device can automatically insert a plurality of needle tubes into needle stands of corresponding numbers in one time.

Description

technical field [0001] The invention relates to a production equipment of medical equipment, in particular to a novel needle tube loading machine for disposable injection needles. technical background [0002] Chinese patent ZL02246461.1 discloses a needle loading machine for disposable injection needles. The needle loading process of this needle loading machine is to scrape the needle tube into the needle drop groove by the scraper. The phenomenon of needle drop and reverse needle occurs, and the needle scraping copper plate of the needle tube machine is easy to wear after a period of use, and the service life is short. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings of the above-mentioned technologies and provide a new type of disposable injection needle that does not cause needle drop during the scraping process of the scraper, does not cause inverted needles, and has a long service life of the scraping copper plate. ...
