Abstract
The present invention discloses a novel device for feeding a needle tube on a disposable injection needle. The novel device for feeding a needle tube on a disposable injection needle comprises a needle taking plate, a needle groove and a needle falling groove, wherein the needle taking plate is provided with an electromagnet attracting device mainly composed of an electromagnet strip, an electromagnetic coil and a capacitor which is connected with the electromagnetic coil in parallel through a forward-reverse transfer switch. The novel device for feeding a needle tube on a disposable injection needle can be used in an automatic needle tip assembling production line and can automatically insert many needle tubes in needle stands with the corresponding number once. The present invention adopts the way that needle tubes are sucked by the electromagnet strip and are put in the needle falling groove after power is cut off. Compared with the prior art, because the present invention utilizes the electromagnet strip to suck needle tubes, the phenomenon that the needles fall can not occur, and the needle can not fall down. After used for a period of time, a copper sheet for scraping needles, which is arranged on a device for feeding a needle tube of the prior art is easy to wear. The present invention replaces the copper sheet for scraping needles with the electromagnet strip, and thus, the wearing phenomenon can not occur.
Description
Technical field
The present invention relates to the winding the needle tube machine of a kind of production equipment of medical apparatus and instruments, particularly a kind of injection needles.
Technical background
Chinese patent ZL02246461.1 discloses a kind of winding the needle tube machine of injection needles, the last pin process of this winding the needle tube machine is by scraping needle plate needle tubing to be blown in the needle tray, in scraping the process of pin, scraper plate is prone to the pin phenomenon, with the phenomenon of falling the pin, scraping of winding the needle tube machine easily causes wearing and tearing after the pin copper coin uses a period of time, and service life is short.
Summary of the invention
The objective of the invention is to provide a kind of scraper plate to scrape and can not occur falling the pin phenomenon in the pin process, can therefore not cause down pin and scrape the winding the needle tube machine of a kind of injection needles of pin copper coin long service life for the deficiency that solves above-mentioned technology.
In order to achieve the above object, the winding the needle tube machine of a kind of injection needles that the present invention is designed, comprise and get needle plate, needle tray and the needle tray that falls, be provided with the electromagnetic actuation device on the needle plate getting, described electromagnetic actuation device mainly is made up of electromagnetism iron bar, solenoid and capacitor, and capacitor is in parallel with solenoid by positive and negative permutator.
During work, after getting needle plate and from needle tray, pushing up last one piece of needle tubing, thereby the energising of electromagnetism iron bar produces magnetic field and holds needle tubing immediately, by cylinder the electromagnetism iron bar is shifted onto on the needle tray then, at this moment deenergization and utilize the capacitor back discharge by the needle tubing demagnetization, make needle tubing fall in the needle tray immediately, thereby reached the purpose of last pin.
The winding the needle tube machine of the resulting a kind of injection needles of the present invention, can be used in the automatic needle point assembly line, can once insert many pieces of needle tubings in the needle stand of corresponding quantity automatically, the winding the needle tube machine of this a kind of injection needles is different fully with former winding the needle tube machine principle: the last pin process of former winding the needle tube machine is by scraping needle plate needle tubing to be blown in the needle tray, the present invention attracts needle tubing by the electromagnetism iron bar, puts into needle tray after outage.Compared with prior art, the winding the needle tube machine of a kind of injection needles of the present invention utilizes the electromagnetism iron bar to attract needle tubing, the pin phenomenon can not occur falling; Can therefore not cause down pin; Because scraping of the winding the needle tube machine of prior art easily causes wearing and tearing after the pin copper coin uses a period of time, and the present invention changes the electromagnetism iron bar into, wear phenomenon can not occur.

Fig. 2 is the partial side TV structure sketch map of Fig. 1;
Fig. 3 is an embodiment electrical equipment principle schematic.
The specific embodiment
The invention will be further described in conjunction with the accompanying drawings below by embodiment.
Embodiment
As Fig. 1, Fig. 2, shown in Figure 3, the winding the needle tube machine of a kind of injection needles that present embodiment is described, comprise and get needle plate 3, needle tray 4 and the needle tray 5 that falls, be provided with electromagnetic actuation device 7 on the needle plate 3 getting, described electromagnetic actuation device 7 mainly is made up of electromagnetism iron bar 1, solenoid 8 and capacitor 10, and capacitor 10 is in parallel with solenoid 8 by positive and negative permutator 9.After getting needle plate 3 and from needle tray 4, pushing up last one piece of needle tubing 2, thereby 1 energising of electromagnetism iron bar produces magnetic field and holds needle tubing 2 immediately, by cylinder 6 electromagnetism iron bar 1 is shifted onto on the needle tray 5 then, at this moment deenergization and utilize capacitor 7 back discharges by needle tubing 2 demagnetizations, make needle tubing 2 fall into immediately in the needle tray 5, thereby reached the purpose of last pin.
