[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A rivet sorting machine includes a vibrating disc, a material guiding assembly, and a screening assembly, wherein:
[0007] The screening component includes an inclined guide rail, a screening hole, a baffle assembly, and a movable partition assembly. The inclined guide rail is located below the discharge end of the material guiding component. The guide surface of the inclined guide rail is wavy. The inclined guide rail has a screening hole. The inclined guide rail is equipped with a baffle assembly for adjusting the size of the screening hole. The inclined guide rail is equipped with a movable partition assembly for adjusting the width of the inclined guide rail.
[0008] Preferably, the material guiding assembly includes a frame and a conical material guiding section, wherein the conical material guiding section is mounted below the discharge end of the vibratory feeder via the frame, and the discharge end of the conical material guiding section faces the feed end of the inclined guide rail.
[0009] Preferably, the hole-blocking assembly includes a baffle, a threaded rod, and a locking nut. The baffle is movably mounted on the inclined guide rail and located between the screen holes. The side of the baffle is provided with a threaded rod that passes through the inclined guide rail. The locking nut is fitted onto the threaded rod and contacts the side of the inclined guide rail.
[0010] Preferably, the movable partition assembly includes baffles and a bidirectional screw. The two baffles are movably mounted on the side of the inclined guide rail, and the bidirectional screw passes through the two baffles and is rotatably mounted on the inclined guide rail.

[0012] This utility model discloses a rivet sorting machine. During operation, the size of the screening holes can be adjusted by a baffle assembly, and the width of the inclined guide rail groove can be adjusted by a movable partition assembly. These two components work together to accommodate the sorting of different types of rivets. Furthermore, the guide assembly buffers the rotational tendency of the rivets as they fall from the vibrating disc onto the conical guide section, allowing them to fall vertically onto the inclined guide rail. This results in a more uniform distribution of rivets on the inclined guide rail. The wavy shape of the guide rail also causes vibration as the rivets move along it, preventing them from piling up and improving sorting efficiency. Attached Figure Description

Detailed Implementation
[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Example:
[0019] Please see Figures 1 to 3 This utility model provides a technical solution: a rivet sorting machine, comprising a vibrating plate 1, a material guiding assembly 2, and a screening assembly 3, wherein:
[0020] The screening component 3 includes an inclined guide rail 31, screening holes 32, a baffle assembly 33, and a movable partition assembly 34. The inclined guide rail 31 is located below the discharge end of the guide component 2. The guide surface of the inclined guide rail 31 is wavy. Rivets fall onto the inclined guide rail 31 after passing through the vibrating plate 1 and the guide component 2. Under the action of their own gravity, the rivets fall along the inclined guide rail 31. The wavy guide surface causes the rivets to vibrate as they fall up and down the inclined guide rail 31, thus preventing the rivets from stacking together. The inclined guide rail 31 has screening holes 32, which can screen out rivets that are not of the correct length. The inclined guide rail 31 is equipped with a baffle assembly 33 for adjusting the size of the screening holes 32, and a movable partition assembly 34 for adjusting the width of the inclined guide rail 31. By adjusting the width of the guide groove of the inclined guide rail 31, it can accommodate the screening of different types of rivets.
[0021] As a preferred embodiment, the vibratory plate 1 is a conventional technical means for those skilled in the art, and its principle and solution will not be described in detail here.
[0022] In a preferred embodiment, the material guiding assembly 2 includes a frame 21 and a conical material guiding section 22. The conical material guiding section 22 is located below the discharge end of the vibratory feeder 1 via the frame 21, and the discharge end of the conical material guiding section 22 faces the feed end of the inclined guide rail 31. By setting the conical material guiding section 22, the rotation tendency of the rivet can be buffered when it falls from the vibratory feeder 1 onto the conical material guiding section 22, so that the rivet can fall vertically onto the inclined guide rail 31 via the conical material guiding section 22.
[0023] In a preferred embodiment, the hole-blocking assembly 33 includes a baffle 331, a threaded rod 332, and a locking nut 333. The baffle 331 is movably mounted on the inclined guide rail 31 and located between the screening holes 32. The baffle 331 forms a sliding pair within the inclined guide rail 31, and can block the screening holes 32. The side of the baffle 331 is provided with a threaded rod 332 that passes through the inclined guide rail 31. The locking nut 333 is fitted onto the threaded rod 332 and contacts the side of the inclined guide rail 31. The baffle 331 is locked by the friction between the locking nut 333 and the inclined guide rail 31.
[0024] In a preferred embodiment, the movable partition assembly 34 includes baffles 341 and a bidirectional screw 342. The two baffles 341 are movably mounted on the side of the inclined guide rail 31, and the bidirectional screw 342 passes through the two baffles 341 and is rotatably mounted on the inclined guide rail 31. The bidirectional screw 342 and the baffles 341 form a threaded engagement, wherein the threads at both ends of the bidirectional screw 342 have opposite directions of rotation, and the parts with opposite directions of rotation of the threads are respectively threaded into the two baffles 341. Thus, rotating the bidirectional screw 342 can drive the two baffles 341 to move closer to or further away from each other.
[0025] As a preferred embodiment, in order to adapt to the wavy inclined guide rail 31, the contact surface between the baffle 331 and the inclined guide rail 31 is also wavy to cooperate with the inclined guide rail 31, so that the rivet will not slip out from between the baffle 331 and the inclined guide rail 31.
[0026] The working principle of this utility model:
[0027] Before using this device, first adjust the position of the baffle 331 according to the type of rivet to adjust the size of the screen hole 32, and then lock the baffle 331 by the threaded rod 332 and the locking nut 333. Then rotate the double-acting screw 342 to adjust the distance between the two baffles 341.
[0028] After adjustment, the rivets are first fed into the vibratory feeder 1. The rivets fall from the conical guide section 22 onto the inclined guide rail 31 through the vibratory feeder 1. When the rivets fall along the inclined guide rail 31 under their own weight, they can be screened out when they encounter the screening hole 32. The qualified rivets fall from the inclined guide rail 31 into the collection box.
[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
