DETAILED DESCRIPTION

[0023] The following is combined with Figure 1 -Attached Figure 8 The utility model is further described in detail:

[0024] The utility model embodiment discloses a universal uninterrupted circulation feeding device for nuts, such as Figure 1 , Figure 2 , Figure 3 , Figure 8 As shown, the utility model is a universal uninterrupted circulation feeding device for nuts, comprising a barrel 1, a feed hopper 11 is fixedly connected to the upper opening of the barrel 1, a cylinder 2 is fixedly installed on the bottom of the barrel 1 by bolts, the gas rod of the cylinder 2 passes through the bottom wall of the barrel 1 and extends into the interior of the barrel 1, and the end of the gas rod of the cylinder 2 is detachably connected to a nut fixture 3; the interior of the barrel 1 is detachably connected to a supporting plate 4 for supporting the nut, a through hole 41 is provided on the top of the supporting plate 4, the gas rod of the cylinder 2 passes through the through hole 41 and can slide in the through hole 41; a through-fiber sensor 5 for detecting the nut position at the top of the nut fixture 3 is provided at the top opening of the barrel 1; in the present embodiment, before starting, the gas rod of the cylinder 2 will retract to the lower side of the supporting plate 4, and only the nut fixture 3 at the top end of the gas rod of the cylinder 2 passes through the through hole 41 and is slightly exposed to the upper side of the supporting plate 4. It is worth noting that during the entire working process, the nut fixture 3 at the top of the gas rod of the cylinder 2 will not pass through the through hole 41 to enter the lower side of the support plate 4. The advantage of this is to prevent the nut from passing through the through hole 41 and entering the lower side of the support plate 4 to cause the cylinder 2 to be stuck. By arranging the support plate 4, the cylinder 2 and the nut fixture 3 in the barrel 1, the nut can be lifted by the cylinder 2 and the nut fixture 3, and after the gas rod of the cylinder 2 reaches the predetermined position, it is taken away by the automatic nut assembly machine, thereby realizing circular feeding. By arranging a counter-fiber optical sensor 5, it is possible to detect whether there is a nut on the top of the nut fixture 3 and whether the nut is in the correct position. Preferably, the number of cylinders 2 is N, and N≥2.

[0025] like Figure 4 , Figure 6 , Figure 7 As shown, a threaded hole 21 is provided at the end of the gas rod of the cylinder 2, and a nut fixture 3 is threadedly connected to the gas rod of the cylinder 2 through the threaded hole 21; in this embodiment, the specific shape of the nut fixture 3 is as follows Figure 6As shown, the nut fixture 3 includes a fixing portion on the upper side and a connecting portion on the lower side. The shape of the fixing portion can match the middle hole of the nut. The side wall of the connecting portion is provided with an internal thread that matches the threaded hole 21. The gas rod of the cylinder 2 is threadedly connected to the nut fixture 3 through the threaded hole 21. It is worth noting that the nut fixture 3 has a variety of specifications and can be installed on the gas rod end of the cylinder 2 through the threaded hole 21. The advantage of this is that it only takes a replacement of the nut fixture 3 to adapt to nuts of various specifications. Compared with a specially molded custom vibration plate, the cost of the nut fixture 3 is lower.

[0026] like Figure 1 , Figure 3 As shown, the side wall of the barrel 1 is movably connected with a discharge door 12, and the discharge door 12 is located on the upper side of the support plate 4; the outer side wall of the barrel 1 is fixedly installed with a discharge hopper 13, and the discharge hopper 13 is located on the lower side of the discharge door 12; in this embodiment, the specific installation positions of the discharge door 12 and the discharge hopper 13 are as shown in Figure 3 , Figure 5 As shown, by providing a discharge door 12 and a discharge hopper 13, it is more convenient to replace nuts of different specifications, and the residual nuts inside can be cleaned by opening the discharge door 12.

[0027] like Figure 3 , Figure 5 , Figure 8 As shown, the side wall of the barrel 1 is provided with a first slide groove 14 and a second slide groove 15, and the side wall of the support plate 4 is provided with a first clamping groove 44 and a second clamping groove 45. The support plate 4 is slidably connected in the first slide groove 14 and forms a clamping fit with the second slide groove 15 through the first clamping groove 44 and the second clamping groove 45; Figure 5 In the figure, the state in which the barrel 1 is not connected to the support plate 4 is shown. The first chute 14 and the second chute 15 are arranged opposite to each other on the side wall of the barrel 1. The length of the second chute 15 is smaller than that of the first chute 14. The specific structure on the support plate 4 is as follows Figure 8 As shown, insert the support plate 4 into the first slide groove 14 and continue to push, the edge of the support plate 4 will enter the second slide groove 15, and the first clamping groove 44 and the second clamping groove 45 of the side wall of the support plate 4 will form a clamping fit with the second slide groove 15, so that the support plate 4 is fixed in the barrel 1. Preferably, the support plate 4 is inclined inside the barrel 1 at an angle of α degrees to the horizontal direction, 10≤α≤60, and the advantage of this is that when the discharge door 12 is opened, the nut will slide down along the support plate 4 into the discharge hopper 13 under the action of gravity.

[0028] The implementation principle of the embodiment of the utility model is:

[0029] Put the nuts from the feed hopper 11 into the barrel 1, and the nuts will accumulate on the top of the support plate 4; start the cylinder 2, and the nut fixture 3 at the end of the air rod of the cylinder 2 will cooperate with the center hole of the nut, so that the nut moves with the air rod of the cylinder 2 to the top opening of the barrel 1. At this time, the opposing optical fiber sensor 5 will detect whether there is a nut on the top of the nut fixture 3 and whether the nut is in the correct position. When it is detected that the nut is at the top of the nut fixture 3, the nut will be taken away by the automatic nut assembly machine; after completing the above operations, the air rod of the cylinder 2 will retract to its original position and extend again, and the above process will be repeated to form a circular feeding.

[0030] When nuts of different specifications are replaced, the discharge door 12 is opened, and the nuts will slide along the supporting plate 4 into the discharge hopper 13 under the action of gravity.

[0031] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The various components mentioned in the utility model are common technologies in the existing field. The technicians in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only to illustrate the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
