[0070] In order to enable any person familiar with the relevant art to understand the technical content of the present invention and implement it accordingly, and according to the content disclosed in this specification, the scope of the patent application and the drawings, any person familiar with the relevant art can easily understand the relevant purposes and advantages of the present invention. Therefore, the detailed features and advantages of the present invention will be described in detail in the implementation mode.

[0071] As Figure 2 、 Figure 3 and Figure 4 shown, this embodiment is a continuous feeding device 100 for a fastener, which includes: a support frame 10; a fixing member 20; a feeding module 30; and a discharging unit 40.

[0072] The support frame 10 serves as the support structure of the entire continuous feeding device 100. That is to say, the support frame 10 is equivalent to the machine table of the continuous feeding device 100.

[0073] The fixing member 20 is a non-movable and non-rotating element. The fixing member 20 can be fixed on the support frame 10 through a fixing shaft 210 by, for example, a screw 90. A fixing member recess 220 is provided on a fixing member vertical surface of the fixing member 20.

[0074] The feeding module 30 includes: a rotating shaft 310; a rotating ring 320; a plurality of material carrying units 330; and a plurality of stretching units 340.

[0075] A rotating shaft 310, which has the same axis as the fixed shaft 210, and the rotating shaft 310 is rotatably sleeved on the outer edge of the fixed shaft 210. Also, the lower part of the rotating shaft 310 can be coupled to the inner side of at least one set of bearings 311, and the bearings 311 can be fixed to the support frame 10 by, for example, screws 90; A rotating ring 320, which is fixedly provided on the rotating shaft 310 with the same axis, and a plurality of rotating ring perforations 321 are provided on the rotating ring 320; When the support frame 10 is further provided with a motor 50 and a belt 510, and the motor 50, the belt 510 and the rotating shaft 310 are rotationally driven and coupled, the motor 50 can drive the rotating shaft 310 and the rotating ring 320 to rotate through the belt 510.

[0076] A material carrying unit 330, which is mainly used to continuously carry the fasteners 60, so as to achieve the purpose of continuous feeding. Each material carrying unit 330 has a magnetic attraction rod 331, and a plurality of sets of magnets 332 arranged in pairs of N poles and S poles are provided inside the magnetic attraction rod 331. Therefore, one fastener 60 will be adsorbed between a set of magnets 332 of N poles and S poles. For example, 3 sets of N pole and S pole magnets 332 means that 3 fasteners 60 can be adsorbed.

[0077] Also, one side of the magnetic attraction rod 331 has a telescopic rod 333. After each telescopic rod 333 penetrates a rotating ring perforation 321, it is coupled to the vertical surface of the fixing member 20 in a sliding contact manner through a telescopic rod end 334 of the telescopic rod 333; Since each telescopic rod 333 penetrates a rotating ring perforation 321, each telescopic rod 333 will be driven by the rotating ring 320 to rotate.

[0078] An extension unit 340, which can be a spring. Each extension unit 340 is sleeved on a telescopic rod 333 and is arranged at the position between the rotating ring 320 and the fixing member 20.

[0079] A discharging unit 40, which has the same axis as the rotating ring 320 and the discharging unit 40 is fixedly provided on the outside of the rotating ring 320, and the discharging unit 40 is vertically and horizontally misaligned and complementary to the interference with the material carrying units 330; In order to enable the magnetic attraction rod 331 to be effectively matched with the discharging unit 40 so as to smoothly unload the fasteners 60 from the magnetic attraction rod 331, therefore, a magnetic attraction surface of each magnetic attraction rod 331 and the outer edge of the discharging unit 40 can have the same curvature.

[0080] In addition, the discharging unit 40 can be arranged as a single discharging ring, or the discharging unit 40 can be composed of a pair of discharging rings arranged vertically and horizontally aligned. Also, the magnetic attraction rods 331 are arranged above or below the single discharging ring, or the magnetic attraction rods 331 are arranged between the discharging units 40.

[0081] Such as Figure 5As shown, when the end 334 of the telescopic rod slides into the recess 220 of the fixing member during the operation of this embodiment, under the action of the extension unit 340, the magnetic attraction rod 331 connected to the end 334 of the telescopic rod will retract into the unloading unit 40. In this way, the fastener 60 adsorbed on the magnetic attraction rod 331 will interfere with the unloading ring, and then under the interference of the unloading ring of the unloading unit 40, the fastener 60 will break away from the magnetic attraction rod 331 and fall downward.

[0082] As Figure 6 shown, and in order to enable the telescopic rod 333 to have sufficient extension space so that the magnetic attraction rod 331 can completely retract to the inner side of the unloading unit 40, the fixing member 20 is particularly arranged eccentrically on the fixed shaft 210. That is, when the fixing member 20 is eccentrically arranged, the first distance d1 between its central axis L1 and the rotating ring 320 on the side of the fastener detachment area 70 is greater than the second distance d2 between the central axis L1 and the rotating ring 320 on the side of the non-fastener detachment area 70. In this way, the recess 220 of the fixing member can be located farther away from the fastener detachment area 70.

[0083] As Figure 7 shown, and when the rotating ring 320 continues to rotate and the end 334 of the telescopic rod disengages from the recess 220 of the fixing member, the magnetic attraction rod 331 connected to the end 334 of the telescopic rod will protrude from the unloading unit 40 again. At this time, the magnetic attraction rod 331 will become a state capable of carrying materials again. And in order to enable the end 334 of the telescopic rod to reach the extended position smoothly, the recess 220 of the fixing member and each end 334 of the telescopic rod are both complementary arc-shaped structures.

[0084] In order to enable smooth continuous feeding, in the continuous feeding device 100 of this embodiment, the top views of the aggregated fixing member 20, the rotating ring 320 and the unloading unit 40 are all circular structures.

[0085] As Figure 8 shown, and in order to adapt to the heights of different fasteners 60, the continuous feeding device 100 further has a lifting module 80. The support frame 10 is slidably combined with the slide rail 810 of the lifting module 80, and the support frame 10 and a lifting screw rod 820 of the lifting module 80 are in an up-and-down moving driving combination relationship. In this way, the lifting module 80 can move the continuous feeding device 100 up and down, so as to adapt to the material carrying operations of fasteners 60 of different heights.

[0086] However, the above embodiments are used to illustrate the features of the present invention. The purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly, rather than to limit the patent scope of the present creation. Therefore, any equivalent modifications or revisions completed without departing from the spirit disclosed by the present invention should still be included in the scope of the above-mentioned patent application.
