The feeding and conveying mechanism can automatically, stably, and accurately convey the bars to the processing positions of processing equipment (such as CNC lathes, cutting machines, grinding machines, etc.), providing a reliable material supply for subsequent processing operations.

The guide columns 16 are inserted into the grooves on the lower side of the rotating frame 14 and are slidably connected thereto.

[0024] One side of the upper end of the rotating frame 14 is fixedly connected to a motor two 13. The output end of the motor two 13 is fixedly connected to one end of the conveying roller 12.

[0025] One end of the connecting plate 6 is threadedly connected to a threaded rod one 18. One end of the threaded rod one 18 is rotatably arranged on the frame 3. One side of the frame 3 is fixedly connected to a motor three 17. The output end of the motor three 17 is fixedly connected to one end of the threaded rod one 18.

[0026] A bar adjusting component is also provided on the frame 1; The bar adjusting component includes cylinders two 30 fixedly connected to both sides of the upper end of the frame 1. The piston ends of the cylinders two 30 are fixedly connected to adjusting plates 29. One side of one end of the adjusting plate 29 is slidably connected to a transverse movement plate 5. One end of the upper side of the transverse movement plate 5 is fixedly connected to a cylinder three 33. The piston end of the cylinder three 33 is fixedly connected to a pressing rod 34.

[0028] One side of the adjusting plate 29 is fixedly connected to a motor five 32. The output end of the motor five 32 is fixedly connected to one end of the threaded rod three 31.

[0029] Specifically, in the prior art, the bar to be conveyed is placed in a protective ring, the lifting roller is driven to rise and contact the bar, and then the lifting roller is driven to rotate to convey the bar. However, before conveying, the staff still needs to manually place the bar in the protective ring at a fixed angle. When there are many bars to be conveyed, the labor intensity of the staff is relatively high. When using a clamping structure such as a manipulator to place multiple bars into the protective ring in sequence, if the multiple bars are stacked messily, it is not easy for the clamping structure such as the manipulator to pick them up one by one, affecting the subsequent conveying efficiency; Therefore, to solve the above problems, in the use of this embodiment, the same batch of bars with the same specifications are used; multiple bars are uniformly arranged and placed on the upper end of the frame 1. Since one side of the upper end of the frame 1 is an inclined plane, the bars will slide toward one side of the frame 1 under the action of gravity, and the outermost bar will be blocked by one side of the frame 1 and stop sliding. Then, the two cylinders 30 on both sides are started simultaneously, so that the two adjusting plates 29 approach the ends of the bars at the same time. Under the action of the two adjusting plates 29, the ends of the multiple arranged bars are made flush. Then, according to the diameter of the bars, the motor 17 drives the threaded rod 18 to rotate, and the distance between the connecting plate 6 and the frame 1 is adjusted until the end of the claw 8 is located below the outermost bar of the frame 1. Then, the motor 9 drives the rotating shaft 7 to rotate, and the multiple claws 8 rotate simultaneously, and use the grooves at their ends to hook up the bar located at the outermost end of the frame 1. The hooked bar will slide along the upper edge of the claw 8, and the claw 8 is connected to one side of the support ring 4, so that the bar falls into the support ring 4. Then, the hydraulic cylinder 11 drives the transmission rod 15 to move horizontally. At the same time, the guide posts 16 on both sides of the transmission block 36 move in the grooves at the bottom of the rotating frame 14, and the rotating frame 14 will rotate due to the push of the guide posts 16. Then, the multiple conveying rollers 12 rise simultaneously and contact the bottom of the bar. Then, the multiple motors 13 are started simultaneously, and the bar moves under the rotation of the conveying rollers 12, so that the bar is conveyed to the designated position. Then, the claw 8 resets, and the subsequent bars will continue to slide due to the loss of support until the outermost bar is blocked by the frame 1. Then, repeat the above operations to enable multiple bars to be sequentially placed at the support ring 4 and conveyed by the conveying rollers 12, thus saving the process of manually placing the bars by workers, reducing the labor intensity of the workers, and moreover, before the multiple bars are conveyed, their ends will be made flush under the cooperation of the two inserting plates 26, and the initial positions are kept consistent, which is beneficial to improving the subsequent processing accuracy; Although the sequential conveying of the bars can be achieved through the above method, it is necessary to arrange the bars on the frame 1. When the bars are uniformly placed on the frame 1, the bars may be in a stacked state, which affects the individual conveying of the bars. Therefore, to avoid this situation, after the bars are placed on the frame 1, the cylinder three 33 can be used to drive the pressure rod 34 to descend, so that the pressure rod 34 squeezes the stacked bars. During the movement of the pressure rod 34, the stacked bars will move to the surrounding due to the extrusion and move into the gaps between two adjacent bars until the distance between the pressure rod 34 and the placement of the bars is equal to the diameter of the bars. At this time, all the bars on the frame 1 will be kept in an arranged state due to the limitation of the pressure rod 34, and when the subsequent bars slide down, the pressure rod 34 will always limit the bars, and there will be no situation where the bars are stacked due to collision when sliding down. Moreover, the transverse movement plate 5 can be transversely moved by driving the rotation of the threaded rod three 31 by the motor five 32, so that the pressure rod 34 does not limit the bars at the outermost end of the frame 1, and does not affect the pushing of the bars by the pawls 8, thereby avoiding the situation where the bars are uniformly placed on the frame 1 and affect the individual conveying of the bars due to the stacked state of the bars.

[0030] In this embodiment, as Figure 8 and Figure 9 shown, one side of the threaded block 35 is threadedly connected with the threaded rod two 21. Both ends of the threaded rod two 21 are rotatably arranged on the fixed plate 19. One end of the fixed plate 19 is fixedly connected with the motor four 20, and the output end of the motor four 20 is fixedly connected with one end of the threaded rod two 21.

[0031] Two second connecting rods 28 are rotatably arranged in the middle of the upper ends of the leftmost and rightmost inserting plates 26, and two first connecting rods 27 are rotatably arranged in the middle of the upper ends of the remaining inserting plates 26. The ends of the second connecting rods 28 are rotatably connected with the ends of the first connecting rods 27, and the ends of two adjacent first connecting rods 27 are rotatably connected.

[0032] One end of the slide rail 24 is fixedly connected with the electric push rod 25, and the piston end of the electric push rod 25 is fixedly connected with one side of the inserting plate 26.

[0033] Specifically, in the above embodiment, although the sequential conveying of the bars can be achieved, it is necessary to arrange the bars obliquely on the frame 1. Due to the gravity of the bars themselves, when they are placed obliquely, the gravity will cause them to have a tendency to slide or roll downward. Under the constraint of the frame 1, this tendency will be converted into the extrusion force between the bars. When the processing time of the bars is relatively long, the staying time of the bars on the frame 1 will also be correspondingly long. When the extrusion force received by the bars exceeds their yield strength for a long time, the bars will be deformed, thus affecting the quality of the bars. Therefore, to solve the above problems, after the bars are arranged obliquely on the frame 1, according to the diameter of the bars, the electric push rod 25 is activated. The electric push rod 25 drives the insertion plate 26 on one side to slide on the slide rail 24. Moreover, with the cooperation of the first connecting rod 27 and the second connecting rod 28, the distance between two adjacent insertion plates 26 is changed until the distance between two adjacent insertion plates 26 is equal to the diameter of the bar. Then, the motor four 20 drives the threaded rod two 21 to rotate, so that the threaded block 35 slides on the slide rod two 22 until the insertion plate 26 at the end of the slide rail 24 aligns with the gap between two adjacent bars at the end of the frame 1. Then, the other insertion plates 26 also align with the gaps between two adjacent bars. At this time, the cylinder one 23 drives the slide rail 24 to move downward, so that multiple insertion plates 26 are inserted into the gaps between two adjacent bars, separating multiple bars from each other, reducing the extrusion force on the bars, thus avoiding the situation that because the bars stay on the frame 1 for a long time, the extrusion force on the bars exceeds their yield strength for a long time, which in turn causes the bars to deform and affects the quality of the bars. Moreover, it does not affect the transportation of the bars at the outermost end of the frame 1; After the bar at the outermost end of the frame 1 moves onto the support ring 4, the slide rail 24 is driven to rise again, and the insertion plate 26 moves away from the bar, causing the bar to slide down again. Then, the insertion plate 26 is driven to insert between two adjacent bars again, and this cycle can be repeated.

[0034] Working principle: Multiple bars are uniformly arranged and placed at the upper end of the frame 1. Since one side of the upper end of the frame 1 is inclined, the bars will slide towards one side of the frame 1 under the action of gravity, and the bar at the outermost end will be blocked by one side of the frame 1 and stop sliding. Then, the cylinders two 30 on both sides are started simultaneously, so that the two adjusting plates 29 approach the ends of the bars at the same time. Under the action of the two adjusting plates 29, the ends of the multiple arranged bars are made flush. Then, according to the diameter of the bars, the motor three 17 drives the threaded rod one 18 to rotate, adjusting the distance between the connecting plate 6 and the frame 1 until the end of the pawl 8 is located below the bar at the outermost end of the frame 1. Then, the motor one 9 drives the rotating shaft 7 to rotate, and the multiple pawls 8 rotate simultaneously, and use the grooves at their ends to hook up the bar at the outermost end of the frame 1. The hooked bar will slide along the upper side edge of the pawl 8, and the pawl 8 is connected to one side of the support ring 4, so that the bar falls into the support ring 4. Then, the hydraulic cylinder 11 drives the transmission rod 15 to move horizontally. At the same time, the guide posts 16 on both sides of the transmission block 36 move in the grooves at the bottom of the rotating frame 14, and the rotating frame 14 will rotate due to the push of the guide posts 16. Then, the multiple conveying rollers 12 rise simultaneously and contact the bottom of the bar. Then, the multiple motors two 13 are started simultaneously. Under the rotation of the conveying rollers 12, the bar moves, and the bar is conveyed to the designated position. Then, the pawl 8 resets. The subsequent bars will continue to slide due to the loss of support until the bar at the outermost end is blocked by the frame 1. Then, repeat the above operations, and multiple bars can be successively placed at the support ring 4 and conveyed by the conveying rollers 12, thus eliminating the process of workers manually placing the bars, reducing the labor intensity of the workers. Moreover, before the multiple bars are conveyed, their ends will be made flush under the cooperation of the two inserting plates 26, and the initial positions are kept consistent, which is beneficial to improving the subsequent processing accuracy. Although the sequential conveying of the bars can be achieved through the above method, however, the bars need to be arranged on the frame 1. When the bars are uniformly placed on the frame 1, the bars may be in a stacked state, thus affecting the individual conveying of the bars. Therefore, to avoid this situation, after the bars are placed on the frame 1, the cylinder three 33 can be used to drive the pressure rod 34 to descend, so that the pressure rod 34 squeezes the stacked bars. During the movement of the pressure rod 34, the stacked bars will move towards the surrounding due to being squeezed and move into the gaps between adjacent two bars until the distance between the pressure rod 34 and the placed bars is equal to the diameter of the bars. At this time, all the bars on the frame 1 will be limited by the pressure rod 34 and remain in an arranged state. Moreover, when the subsequent bars slide, the pressure rod 34 always limits the bars, and there will be no situation where the bars are stacked due to collision when sliding. And, the transverse movement plate 5 can be made to move horizontally by driving the threaded rod three 31 to rotate by the motor five 32, so that the pressure rod 34 does not limit the bar at the outermost end of the frame 1, and does not affect the pushing of the bar by the pawl 8, thus avoiding the situation that when the bars are uniformly placed on the frame 1, due to the stacked state of the bars, it affects the individual conveying of the bars.After the bars are arranged obliquely on the frame 1, according to the diameter of the bars, the electric push rod 25 is activated. The electric push rod 25 drives the insertion plate 26 on one side to slide on the slide rail 24. And, with the cooperation of the first connecting rod 27 and the second connecting rod 28, the distance between two adjacent insertion plates 26 changes until the distance between two adjacent insertion plates 26 is equal to the diameter of the bars. Then, the motor four 20 drives the threaded rod two 21 to rotate, so that the threaded block 35 slides on the slide rod two 22 until the insertion plate 26 at the end of the slide rail 24 aligns with the gap between two adjacent bars at the end of the frame 1. Then the other insertion plates 26 also align with the gaps between two adjacent bars. At this time, the cylinder one 23 drives the slide rail 24 to move downward, so that multiple insertion plates 26 are inserted into the gaps between two adjacent bars, making multiple bars separated from each other, reducing the extrusion force on the bars, thus avoiding the situation that because the bars stay on the frame 1 for a long time, the extrusion force on the bars exceeds its yield strength for a long time, which in turn causes the bars to deform and affects the quality of the bars. And, it does not affect the transportation of the bars at the outermost end of the frame 1; when the bars at the outermost end of the frame 1 move onto the support ring 4, the slide rail 24 is driven to rise again, and the insertion plate 26 moves away from the bars, causing the bars to slide down again. Then the insertion plate 26 is driven to insert between two adjacent bars again, and so on in a cycle.
