[0034] Please refer to Figure 1 and Figure 2 A guide plate device of nut elevator inlet, comprising a mounting frame 1, a first guide plate 2, a second guide plate 3 and an adjusting mechanism 4.

[0035] The first guide plate 2 is fixedly connected to the top of the mounting frame 1, which is inclined, with the upper side as the inlet and the lower side as the outlet. The inlet is deviated to the first side, and the outlet is deviated to the second side.

[0036] The middle part of the second guide plate 3 is hinged to the mounting frame 1. More specifically, the mounting frame 1 can be composed of a bottom plate 1c and two groups of support bars 1d fixedly connected to the bottom plate 1c. The first guide plate 2 is fixedly connected to the top end of the support bar 1d, and the second guide plate 3 is hinged between the two support bars 1d on the second side.

[0037] The second guide plate 3 is also connected to the outlet on the lower side of the first guide plate 2. That is, the second guide plate 3 has a suitable length, and the nuts falling from the outlet on the lower side of the first guide plate 2 enter the second guide plate 3.

[0038] In some embodiments, the first guide plate 2 is provided with a plurality of guide grooves 2a.

[0039] The threaded nut, after falling into the first guide plate 2, will fall along the guide grooves 2a.

[0040] The second side portion of the second guide plate 3 is beyond the first guide plate 2, and the first side portion is below the first guide plate 2.

[0041] Please refer to Figure 2 The adjusting mechanism 4 is installed on the mounting frame 1 and acts on the first side portion of the second guide plate 3, so that the second guide plate 3 is kept in a more gentle inclined state than the first guide plate 2, and the inclination angle can also be adjusted. That is, the inclination directions of the second guide plate 3 and the first guide plate 2 are the same, and the outlets at the lower sides are all inclined to the second side, but the inclination angle of the second guide plate 3 is smaller than that of the first guide plate 2.

[0042] The threaded nut, after falling into the first guide plate 2, will fall along the guide grooves 2a.

[0043] In some embodiments, a pneumatic cylinder can be used as the driving mechanism. More specifically, the cylinder body of the pneumatic cylinder is hinged to the mounting frame 1, and the piston rod is hinged to the first side portion of the second guide plate 3.

[0044] Please refer to Figure 2 and Figure 4 In some embodiments, the adjusting mechanism 4 can include a lead screw 4a and a moving block 4b. The lead screw 4a is rotatably connected to the mounting frame 1 about a vertical axis. More specifically, two upper and lower mounting plates 1d1 can be fixedly connected between the two support strips 1d at the first side, and the lead screw 4a can be rotatably connected to the two mounting plates 1d1 at both ends using bearing seats. The moving block 4b is slidingly connected to the mounting frame 1. More specifically, two vertical guide rods 4b1 can be fixedly connected between the two mounting plates 1d1, and the moving block 4b is slidingly connected to the two guide rods 4b1 using linear bearings. The moving block 4b is also provided with a matching nut for the lead screw 4a, that is, the rotation of the lead screw 4a drives the moving block 4b to move up and down, and the self-locking of the lead screw 4a keeps the moved moving block 4b in the corresponding position. The moving block 4b is also connected to the first side portion of the second guide plate 3 and forms a slot-pin pair. That is, the movement of the moving block 4b drives the second guide plate 3 to swing, and the inclination angle of the second guide plate 3 is adjusted.

[0045] Compared with using a cylinder, the screw rod 4a is more accurate, easier to control and more convenient to use.

[0046] Referring to Figure 2 and Figure 4 In some embodiments, based on the above-mentioned embodiment that the adjusting mechanism 4 can include the screw rod 4a and the moving block 4b, the first side part of the second guide plate 3 is two elongated pieces 3c provided with a waist-shaped slot. The moving block 4b is between the two elongated pieces 3c, and a pin column is arranged on both sides of the moving block 4b to form a slot-pin pair with the waist-shaped slot. The second ends of the two elongated pieces 3c are detachably connected with a connecting strip 3c1.

[0047] After the connecting strip 3c1 is installed, the two elongated pieces 3c are not easy to bend and deform, and the slot-pin pair formed between the two elongated pieces 3c and the moving block 4b is stable. After the connecting strip 3c1 is removed, the two elongated pieces 3c can bend and deform to conveniently release or establish the slot-pin pair between the two elongated pieces 3c and the moving block 4b.

[0048] Referring to Figure 3 In some embodiments, based on the above-mentioned embodiment that the adjusting mechanism 4 can include the screw rod 4a and the moving block 4b, the mounting frame 1 includes a lower frame body 1a and an upper frame body 1b detachably connected to the lower frame body 1a. The lower frame body 1a is used for rotatably connecting the lower end of the screw rod 4a, and the upper frame body 1b is used for rotatably connecting the upper end of the screw rod 4a. More specifically, the two groups of support strips 1d are each divided into an upper part and a lower part, the lower part is fixedly connected to the bottom plate 1c, and the upper part is fixedly connected to the first guide plate 2; for the two mounting plates 1d1, one is mounted between the lower parts of the two support strips 1d on the first side, and the other is mounted between the upper parts of the two support strips 1d on the first side. Correspondingly, the two mounting plates 1d1 can not use bearing seats, but can directly embed bearings after bearing grooves are formed, and can not use screws to install the guide rod 4b1, but can form insertion grooves for inserting the light shaft.

[0049] The installation of the adjusting mechanism 4 is more convenient. In addition, for the two support strips 1d on the second side, the upper part and the lower part can each be provided with a semicircular groove, so that the hinging between the second guide plate 3 and the mounting frame 1 is also more convenient.

[0050] Referring to Figure 5 and Figure 6In some embodiments, the second guide plate 3 comprises a first plate body 3a and a second plate body 3b. The first plate body 3a is used to be hinged with the mounting rack 1 and connected with the adjusting mechanism 4. The second plate body 3b is telescopically fixedly connected with the first plate body 3a. More specifically, a slide rail with damping can be used between the second plate body 3b and the first plate body 3a; the second plate body 3b can also be provided with a magnet for adsorbing the first plate body 3a. By manually overcoming the damping or magnetic force, the second plate body 3b can be telescopically moved relative to the first plate body 3a, and after adjustment, the second plate body 3b can be kept fixed relative to the first plate body 3a by the damping or magnetic force.

[0051] The telescopic movement of the second plate body 3b relative to the first plate body 3a can adjust the distance required for the nut to fall up and down on the second plate body 3b, and combined with the adjustment of the inclination angle of the second guide plate 3, the range of adaptation is larger.
