Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are all within the protection scope of the present utility model.

[0025] Reference Figures 1-6 A screw production screening device includes a base 1, an inclined frame 2 welded to the upper surface of the base 1, a motor bolted to one side of the inclined frame 2, and a first screen cylinder 5 with an upwardly inclined opening bolted to one end of the motor output shaft. The first screen cylinder 5 has multiple evenly distributed second screen grooves 12 on its body. A second screen cylinder 6 is welded to the outside of the first screen cylinder 5, and its body has multiple evenly distributed first screen grooves 11. The opening of the first screen grooves 11 is smaller than that of the second screen grooves 12. A placement groove 8 is provided on the upper surface of the base 1, and a collection box 7 is placed in the placement groove 8. When screening is required, screws are poured into the first screen cylinder 5, and then the motor is started. The motor drives the first screen cylinder 5 to rotate. Because the first screen cylinder 5 and the second screen cylinder 6 are in close proximity, the screws are separated into two screens. Since the sieve cylinders 6 are fixed together, the first sieve cylinder 5 will drive the second sieve cylinder 6 to rotate. Because the screws are of different sizes, the screw heads are of different sizes. Therefore, during the rotation of the first sieve cylinder 5, screws with heads smaller than the second sieve groove 12 will enter the second sieve cylinder 6, while screws with heads larger than the second sieve groove 12 will remain in the first sieve cylinder 5. The screws that enter the second sieve cylinder 6 will be screened through the first sieve groove 11 on the second sieve cylinder 6. Screws with heads smaller than the first sieve groove 11 will fall into the collection box 7 for collection, while screws with heads larger than the first sieve groove 11 will remain in the second sieve cylinder 6. This allows for multi-stage screening of screws of different sizes, eliminating the need for manual screening, saving time and improving efficiency.

[0026] During the screw screening process, if the screw shaft enters the first screen groove 11 or the second screen groove 12, the screw will rotate with the first screen cylinder 5 or the second screen cylinder 6. When the screw rotates to the top, it will fall down under the action of gravity, thus preventing the screw from getting stuck in the first screen groove 11 or the second screen groove 12.

[0027] In this invention, a pushing assembly 4 is provided inside the first screen cylinder 5 to push out materials from the first screen cylinder 5 and the second screen cylinder 6. The pushing assembly 4 includes a push plate 20, which is disposed inside the first screen cylinder 5. A lead screw 15 is rotatably connected to the bottom inner wall of the first screen cylinder 5 via a bearing, and the lead screw 15 passes through the push plate 20 and is threadedly connected to the push plate 20. Two fixing rods 24 are welded to one side of the push plate 20. A retaining ring 24 is provided inside the first screen cylinder 5 at the cylinder opening. A connecting plate 19 is welded inside the retaining ring 24, and the connecting plate 19 is fixed to the fixing rods 24. A through hole is opened on one side of the connecting plate 19, and the lead screw 15 passes through the through hole. The outer wall of the first screen cylinder 5 and the second screen cylinder 6 are connected. A push ring 22 is provided between the inner walls of the second screen cylinder 6. A retaining ring 13 is provided at the opening of the cylinder. Two connecting rods 23 are welded between the retaining ring 13 and the push ring 22. After screening, the collection box 7 is taken out from the placement groove 8, and a new collection box 7 is placed. Then, the screw 15 is rotated. The screw 15 engages with the push plate 20 through the thread, which causes the push plate 20 to move towards the opening of the first screen cylinder 5. The push plate 20 pushes the connecting plate 19 to move through the fixing rod 24. The connecting plate 19 drives the retaining ring 14 to move, causing the retaining ring 14 to disengage from the first screen cylinder 5. Thus, the screw in the first screen cylinder 5 is pushed out through the push plate 20, causing the screw to fall into the new collection box 7.

[0028] The first retaining ring 13 and the second retaining ring 14 are connected by a telescopic assembly, which includes two sliding rods 18. Both sliding rods 18 are welded to one side of the first retaining ring 13. A sleeve 17 is slidably connected to the outer side of each sliding rod 18. A connecting frame 16 is welded to one end of the sleeve 17 and is fixed to the second retaining ring 14. Two symmetrically distributed sliding grooves 27 are formed on the inner wall of the sleeve 17. A slider 28 is slidably connected within the sliding grooves 27 and is fixed to the sliding rod 18. Multiple guide blocks 21 are welded to the outer side of the push ring 22, moving along the groove direction of the first screen groove 11. During the movement of the second retaining ring 14, the connecting frame 16 drives the sleeve 17 to move. During this movement, the sleeve 17 causes the slider 28 to move within the sliding grooves 27. When the push plate 20 pushes out all the screws in the first sieve cylinder 5, the slider 28 will move to the other end of the slide groove 27. After replacing the new collection box 7, the second retaining ring 14 will continue to move. At this time, the sleeve 17 will drive the slide rod 18 to move through the slider 28. The slide rod 18 will drive the first retaining ring 13 to move, so that the first retaining ring 13 will disengage from the second sieve cylinder 6. At the same time, the first retaining ring 13 will drive the push ring 22 to move along the groove direction of the first sieve groove 11 through the guide block 21 through the connecting rod 23. This will push the screws in the second sieve cylinder 6 out, so as to facilitate the removal of the screws in the first sieve cylinder 5 and the second sieve cylinder 6. At the same time, it can realize graded removal and avoid the screws in the first sieve cylinder 5 and the second sieve cylinder 6 from mixing again.

[0029] During the screening process, the first baffle ring 13 and the second baffle ring 14 will block the openings of the second screen cylinder 6 and the first screen cylinder 5 to prevent the material from falling from the openings.

[0030] The lead screw 15 is threaded with a locking nut on the outside. The locking nut locks and fixes the lead screw 15, so that the lead screw 15 will not rotate easily. At the same time, when it is necessary to rotate the lead screw 15, the locking nut on the lead screw 15 should be rotated away from the connecting plate 19.

[0031] In this invention, a support plate 3 is welded to one side of the inclined frame 2, and a fixing ring 9 is welded to one side of the support plate 3. An annular groove 10 is provided on the bottom outer wall of the first screen cylinder 5, and the fixing ring 9 is rotatably connected to the annular groove 10. The fixing ring 9 on the support plate 3 is rotatably connected to the annular groove 10 on the bottom outer wall of the first screen cylinder 5, providing stable support for the rotation of the first screen cylinder 5, so that the entire screening device can operate stably and efficiently to complete the production screening of screws. Elastic balls 26 are glued to both outer walls of the collection box 7, and grooves 25 are provided on both sides of the placement groove 8, and the elastic balls 26 are engaged with the grooves 25. The collection box 7 is engaged with the grooves 25 on both sides of the placement groove 8 through the elastic balls 26, which facilitates the installation and disassembly of the collection box 7 and makes it convenient to collect and clean the screened screws.

[0032] Working principle: When screening is required, screws are poured into the first screen cylinder 5, and then the motor is started. The motor will drive the first screen cylinder 5 to rotate. Since the first screen cylinder 5 and the second screen cylinder 6 are fixed, the first screen cylinder 5 will drive the second screen cylinder 6 to rotate. Since the screws are of different sizes, the screw heads are of different sizes. Therefore, during the rotation of the first screen cylinder 5, screws with heads smaller than the second screen groove 12 will enter the second screen cylinder 6, while screws with heads larger than the second screen groove 12 will remain in the first screen cylinder 5. The screws that enter the second screen cylinder 6 will be screened through the first screen groove 11 on the second screen cylinder 6. Screws with heads smaller than the first screen groove 11 will fall into the collection box 7 for collection, while screws with heads larger than the first screen groove 11 will remain in the second screen cylinder 6. This allows for multi-stage screening of screws of different sizes, eliminating the need for manual screening, saving time and improving efficiency.

[0033] During the screw screening process, if the screw shaft enters the first screen groove 11 or the second screen groove 12, the screw will rotate with the first screen cylinder 5 or the second screen cylinder 6. When the screw rotates to the top, it will fall down under the action of gravity, thus preventing the screw from getting stuck in the first screen groove 11 or the second screen groove 12.

[0034] During the screening process, retaining ring 13 and retaining ring 24 will block the openings of the second screen cylinder 6 and the first screen cylinder 5 to prevent material from falling out of the openings. After screening is completed, the collection box 7 is removed from the placement slot 8, and a new collection box 7 is placed. Then, the locking nut on the screw 15 is rotated away from the connecting plate 19. At this time, rotating the screw 15 will cause the push plate 20 to move towards the opening of the first screen cylinder 5 through the thread engagement between the screw 15 and the push plate 20. The push plate 20 will push the connecting plate 19 to move through the fixing rod 24. The connecting plate 19 will drive the retaining ring 24 to move, causing the retaining ring 24 to disengage from the first screen cylinder 5. This will push the screw in the first screen cylinder 5 out through the push plate 20, causing the screw to fall into the new collection box 7. During the movement of the retaining ring 24, the sleeve 17 will be driven by the connecting frame 16. During the movement of the sleeve 17, the slider 28 moves within the groove 27. After the push plate 20 pushes out all the screws in the first sieve cylinder 5, the slider 28 moves to the other end of the groove 27. After replacing the new collection box 7, the second retaining ring 14 continues to move. At this time, the sleeve 17 moves the slide rod 18 through the slider 28, and the slide rod 18 moves the first retaining ring 13, causing the first retaining ring 13 to disengage from the second sieve cylinder 6. Simultaneously, the first retaining ring 13 moves the push ring 22 through the connecting rod 23 along the groove direction of the first sieve groove 11 via the guide block 21, thereby pushing out the screws in the second sieve cylinder 6. This facilitates the removal of screws from the first sieve cylinder 5 and the second sieve cylinder 6, and enables graded removal, preventing the screws in the first sieve cylinder 5 and the second sieve cylinder 6 from mixing again.

[0035] Meanwhile, the fixing ring 9 on the support plate 3 is rotatably connected to the annular groove 10 on the bottom outer wall of the first screen cylinder 5, providing stable support for the rotation of the first screen cylinder 5, so that the entire screening device can operate stably and efficiently to complete the production screening of screws.

[0036] The collection box 7 is engaged with the grooves 25 on both sides of the placement slot 8 by the elastic ball 26, which facilitates the installation and disassembly of the collection box 7 and makes it convenient to collect and clean the screened screws.

[0037] Furthermore, the terms "installation," "setup," "connection," and "socketing" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral constructions; they can refer to mechanical or electrical connections; they can refer to direct connections or indirect connections via an intermediate medium, or internal connections between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.
