Embodiment

[0012] As shown in Fig. 1, Fig. 2 and Fig. 3, a needle loading machine for disposable injection needles described in this embodiment includes a needle taking plate 3, a needle groove 4 and a needle drop groove 5, and a needle taking plate 3 is provided with There is an electromagnet pull-in device 7, and the electromagnet pull-in device 7 is mainly composed of an electromagnet strip 1, an electromagnetic coil 8 and a capacitor 10, and the capacitor 10 is connected in parallel with the electromagnetic coil 8 through a forward and reverse 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 tube 2 can be drop...

Abstract

The invention discloses a novel device for feeding syringe on disposable injection needle, which comprises a needle fetching board, a needle slot and a needle drop slot, the needle fetching board is provided with an electromagnet adhesive apparatus, which comprises an electromagnet strip, a magnet coil and a condenser block, the condenser can be in parallel connection with the magnet coil through a positive-negative transfer switch. 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 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 technology and provide a disposable injection needle that does not cause needle drop during the needle scraping process with a scraper, does not cause inverted needles, and has a long service life of the scraping copper plate. Needle machi...
