[0012] Preferably, a moving rod is fixedly connected to the inner wall of the vertical bar, and the moving rod is a round rod-shaped structure. An elastic rope is fixedly connected to one side of the sliding block, and one end of the elastic rope is fixedly connected to the fixed block.

[0013] Preferably, the bottom of the fixed block is fixedly connected to the top of the material storage trough, and the top of the material storage trough is fixedly connected with a baffle, which is used to limit the sliding block.

[0014] Preferably, a limit baffle is fixedly connected to the bottom of the conveying frame, one side of the limit baffle is an arc-shaped surface, and an outer wall of the moving rod is provided with a power-assisting mechanism.

[0015] Preferably, the power-assisting mechanism comprises a rotating sleeve, the inner wall of the rotating sleeve is rotatably connected to the outer wall of the moving rod, the bottom of the rotating sleeve is fixedly connected to a scraper plate, and the bottom of the scraper plate is rotatably connected to a rotating shaft.

[0016] Preferably, an opening and closing plate is fixedly connected to the bottom of the rotating shaft, one side of the opening and closing plate contacts a stopper, the top of the stopper is fixedly connected to the bottom of the scraping plate, and the stopper serves to limit and block the opening and closing plate.

[0017] The present invention provides a fastener conveying device having the following beneficial effects:

[0018] 1. The present invention sets a fastener conveying mechanism, and the screws in the storage trough are dug up and embedded into the conveying trough along with the conveying trough opened on the inner wall of the conveying frame. At the same time, the width and height of the nut are larger than the inner wall of the conveying trough, so the nut cannot enter the conveying trough. When the conveying trough is driven and lifted, the conveying trough will tilt the screw column contained in the inner wall to the left, so that the screw column slides along the inner wall of the conveying trough into the dumping plate, and slides out from the inclined dumping plate to the unloading place, completing the natural sorting of the screw column and the nut, and performing the work of synchronous transmission.

[0019] 2. The present invention sets up a fastener conveying mechanism, and the screw column that is magnetically attached to the rotating ball will have a close friction with the rotating ball. Therefore, when the conveying frame is lifted, the screw column that is magnetically attached to the conveying slot will not fall off. After the conveying frame is lifted, the screw column will drive the rotating ball to roll with its own gravity, and the rolling of the rotating ball will reduce the sliding friction generated between the screw column and the inner wall of the conveying slot, thereby further improving the stability of the screw column during material unloading and reducing the occurrence of squeezing and jamming problems. At the same time, it also ensures that the screw column can be stably filled into the conveying slot to avoid slipping problems.

[0020] 3. The present invention is provided with a push-down mechanism, so that when the moving rod completes the movement of the conveying frame surface, other screw columns and excess nuts that are magnetically attracted to the surface of the conveying frame due to the magnetic attraction of the magnetic plate can be automatically scraped off, so that no excess fasteners are attached to the outside of the conveying trough, ensuring that the screw columns that naturally slide toward the power-assisting mechanism in the conveying trough can be discharged in an orderly and uniform manner, reducing the probability of errors in fastener sorting, and ensuring that the screw columns can be fully separated from the nuts.

[0021] 4. The present invention sets a push-down mechanism and utilizes a scraper plate to contact the top of the conveyor frame. The scraper plate presses against the top of the conveyor frame and drives the rotating sleeve to rotate, so that the bottom of the scraper plate can freely fit the inclined surface of the top of the conveyor frame under different rotations, and utilizes the scraper plate to complete the angle-adjusting scraping effect on the top of the conveyor frame, ensuring that the scraper plate can stably move along the top of the conveyor frame and can automatically adjust according to the different rotation angles of the conveyor frame to complete a uniform and stable moving scraping effect.

[0022] 5. The present invention sets up an assist mechanism. When the scraper plate moves to the right on the conveying frame, the opening and closing plate contacts the screw column in the conveying groove below. It will be blocked by the screw column and drive the rotating shaft to rotate and lift, without pushing the screw column, thereby realizing the dumping of the screw column on the conveying frame. The opening and closing plate can assist in dumping the screw column, avoiding the problem of squeezing and jamming of the screw column due to the obstruction of some metal particles when the screw column moves on the rotating ball, and further improving the feeding efficiency of the screw column.

DETAILED DESCRIPTION

[0035] Example 1: Please refer to Figure 1-7 The present invention provides a technical solution: a fastener conveying device, comprising a storage trough 2, a support plate 1 fixedly connected to one side of the storage trough 2, a dumping plate 8 fixedly connected to the top of the support plate 1, a fixing seat 6 fixedly connected to one side of the storage trough 2, and a fastener conveying mechanism 3 provided on the top of the storage trough 2;

[0036] The fastener transmission mechanism 3 includes:

[0037] The motor 301 has a bottom portion fixedly connected to the top of the fixing base 6, a movable shaft 302 fixedly connected to the top of the motor 301, and a hinge plate 303 fixedly connected to one side of the movable shaft 302. The motor 301 is used to support the movable shaft 302;

[0038] The conveying frame 304 is a strip-shaped plate structure. The bottom of the conveying frame 304 is fixedly connected to the top of the hinge plate 303. The inner wall of the conveying frame 304 is provided with a conveying groove 305. The conveying groove 305 is a long strip-shaped groove. The conveying frame 304 is used to hold fasteners.

[0039] A magnetic plate 306 is fixedly connected to the inner wall of the conveying trough 305, and a rotating ball 307 is rotatably connected to the inner wall of the magnetic plate 306. The magnetic plate 306 has magnetism.

[0040] When the screws and nuts are mixed in the storage trough 2 and the screws and nuts need to be separated and used separately, the screws need to be transported out. At this time, the motor 301 is started to control the movable shaft 302 to mechanically lift and lower back and forth, so that the movable shaft 302 drives the hinged plate 303 and the top conveying frame 304 to rise and fall synchronously. The conveying groove 305 opened on the inner wall of the conveying frame 304 digs the screws in the storage trough 2 and embeds them into the conveying groove 305. At the same time, the nut width and height are larger than the inner wall of the conveying groove 305, so the nut cannot enter the conveying groove 305. When the conveying groove 305 is driven and lifted, the conveying groove 305 will tilt the screw column contained in the inner wall to the left, so that the screw column slides along the inner wall of the conveying groove 305 to the dumping plate 8, and slides outward from the inclined dumping plate 8 to the unloading place, completing the natural sorting of the screw column and the nut, and performing the work of synchronous transmission;

[0041] When the conveying frame 304 descends and sinks into the pile of screws and nuts, the screws will flow into the conveying slot 305 and be attracted by the magnetic attraction of the magnetic plate 306 in the conveying slot 305, and the screws will be magnetically sucked into the conveying slot 305 and placed on the rotating ball 307. The rotating ball 307 rotates in one direction, and the rotating ball 307 cannot rotate to the right, but can only drive the screw above to move to the left, so that the screws that are magnetically attached to the rotating ball 307 will be tightly attached to the rotating ball 307. Therefore, when the conveying frame 304 is lifted, the screw column magnetically attracted in the conveying slot 305 will not fall off. After the conveying frame 304 is lifted, the screw column will drive the rotating ball 307 to roll due to its own gravity. The rolling of the rotating ball 307 reduces the sliding friction between the screw column and the inner wall of the conveying slot 305, thereby further improving the stability of the screw column when unloading, reducing the occurrence of squeezing and jamming problems, and at the same time ensuring that the screw column can be stably filled into the conveying slot 305 to avoid slipping problems.

[0042] Example 2: Please refer to Figure 1-10 Based on the first embodiment, the present invention provides a technical solution: a push-down mechanism 4 is provided on the top of the storage trough 2, and the push-down mechanism 4 includes a sliding block 401, the bottom of the sliding block 401 is fixedly connected to the top of the storage trough 2, and the top of the sliding block 401 is fixedly connected to a vertical bar 404.

[0043] A moving rod 405 is fixedly connected to the inner wall of the vertical bar 404 . The moving rod 405 is a round rod-shaped structure. An elastic rope 402 is fixedly connected to one side of the sliding block 401 . One end of the elastic rope 402 is fixedly connected to the fixed block 403 .

[0044] The bottom of the fixed block 403 is fixedly connected to the top of the storage trough 2 , and a baffle 406 is fixedly connected to the top of the storage trough 2 . The baffle 406 is used to limit the sliding block 401 .

[0045] The bottom of the conveying frame 304 is fixedly connected to a limit baffle 407, one side of the limit baffle 407 is an arc-shaped surface, and the outer wall of the moving rod 405 is provided with a power-assisting mechanism 5;

[0046] When the conveyor frame 304 is lifted, the top of the conveyor frame 304 contacts the moving rod 405. Before the conveyor frame 304 is lifted to the horizontal, the top of the conveyor frame 304 will contact the moving rod 405 and push the moving rod 405. Since the moving rod 405 is restricted by the vertical bar 404, when the moving rod 405 is pushed by the inclined conveyor frame 304, the moving rod 405 will drive the vertical bar 404 and the sliding block 401 to move horizontally to the right on the storage trough 2. As the conveyor frame 304 continues to lift, the moving rod 405 will be pushed to the horizontal. The rod 405 is continuously pushed to the right, so that the moving rod 405 can automatically scrape off other screws and excess nuts that are magnetically attracted to the surface of the conveying frame 304 due to the magnetic attraction of the magnetic plate 306 during the process of moving the moving rod 405 to the right, so that no excess fasteners are attached to the outside of the conveying trough 305, ensuring that the screws that naturally slide toward the tipping plate 8 in the conveying trough 305 can be discharged in an orderly and uniform manner, reducing the probability of errors in fastener sorting and ensuring that the screws can be fully separated from the nuts;

[0047] When the conveyor frame 304 continues to rise, the moving rod 405 slides to the position of the limit baffle 407 and moves to the side of the limit baffle 407 as the conveyor frame 304 continues to rise. After the conveyor frame 304 is raised, the screw column in the inner wall conveying groove 305 is tilted. Then, when the conveyor frame 304 is lowered, the moving rod 405 slides to the side of the limit baffle 407 onto the conveyor frame 304. As the conveyor frame 304 continues to fall, the moving rod 405 and the sliding block 401 are continuously pulled back to their original position by the elastic force of the elastic rope 402.

[0048] Example 3: Please refer to Figure 1-11 Based on the first and second embodiments, the present invention provides a technical solution: the power assist mechanism 5 includes a rotating sleeve 501, the inner wall of the rotating sleeve 501 is rotatably connected to the outer wall of the moving rod 405, the bottom of the rotating sleeve 501 is fixedly connected to a scraper plate 502, and the bottom of the scraper plate 502 is rotatably connected to a rotating shaft 503.

[0049] The bottom of the rotating shaft 503 is fixedly connected to an opening and closing plate 504. One side of the opening and closing plate 504 contacts a stopper 505. The top of the stopper 505 is fixedly connected to the bottom of the scraping plate 502. The stopper 505 serves to limit the opening and closing plate 504.

[0050] When the moving rod 405 scrapes from right to left on the conveyor frame 304, the rotating sleeve 501 on the outer wall of the moving rod 405 is pulled downward by the counterweight of the scraping plate 502, and the scraping plate 502 contacts the top of the conveyor frame 304, and the scraping plate 502 presses against the top of the conveyor frame 304 to drive the rotating sleeve 501 to rotate, so that the bottom of the scraping plate 502 can freely fit the inclined surface of the top of the upper conveyor frame 304 under different rotations, and the scraping plate 502 is used to complete the angle self-adjusting scraping effect on the top of the conveyor frame 304, ensuring that the scraping plate 502 can stably move along the top of the conveyor frame 304, and can automatically adjust according to the different rotation angles of the conveyor frame 304, completing a uniform and stable moving scraping effect;

[0051] When the scraper plate 502 slides to the left along the surface of the conveying frame 304, the opening and closing plate 504 at the bottom of the scraper plate 502 will be driven to move to the left synchronously, and the opening and closing plate 504 will be used to extend down into the conveying groove 305, so that the fasteners in the conveying groove 305 can be pushed stably when the conveying frame 304 is tilted. When the scraper plate 502 moves to the right on the conveying frame 304, the opening and closing plate 504 will be blocked by the screw column when it contacts the screw column in the conveying groove 305 below, and the rotating shaft 503 will be driven to rotate and lift up without pushing the screw column, thereby realizing the tipping of the screw column in the conveying frame 304. The opening and closing plate 504 can play a role in assisting the tipping of the screw column, avoiding the problem of the screw column being squeezed and stuck due to the obstruction of some metal particles when moving on the rotating ball 307, and further improving the efficiency of the screw column blanking.
