[0048] One side of the upper end of the rotating frame 14 is fixedly connected to the motor 2 13 , and the output end of the motor 2 13 is fixedly connected to one end of the conveying roller 12 .

One end of the connecting plate 6 is fixedly connected to a motor 9, and the output end of the motor 9 is fixedly connected to one end of the rotating shaft 7.

[0050] The frame 1 is also provided with a bar adjustment assembly;

[0051] The rod adjustment assembly includes a cylinder 2 30 fixedly connected to both sides of the upper end of the frame 1, the piston end of the cylinder 2 30 is fixedly connected to the adjustment plate 29, one side of the adjustment plate 29 is slidably connected to the transverse plate 5, one end of the upper side of the transverse plate 5 is fixedly connected to the cylinder 3 33, and the piston end of the cylinder 3 33 is fixedly connected to the pressure rod 34.

[0052] One end of the transverse plate 5 is threadedly connected to a threaded rod 31 , and both ends of the threaded rod 31 are rotatably arranged on the adjustment plate 29 .

[0053] One side of the adjustment plate 29 is fixedly connected to a motor 5 32 , and an output end of the motor 5 32 is fixedly connected to one end of the threaded rod 3 31 .

[0054] Specifically, in the prior art, the bars to be transported are placed in a protective ring, the lifting rollers are driven to rise and contact the bars, and then the lifting rollers are driven to rotate to transport the bars. However, before transporting, workers are required to manually place the bars into the protective ring at a fixed angle. When there are many bars to be transported, the workers have a high labor intensity. When a clamping structure such as a manipulator is used to place multiple bars into the protective ring in sequence, if the multiple bars are piled up in a disorderly manner, it is difficult for the manipulator or other clamping structure to pick them up one by one, which affects the subsequent transport efficiency.

[0055] Therefore, in order to solve the above problem, this embodiment is used for a batch of rods with the same specifications; multiple rods 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 surface, the rods will slide toward the side of the frame 1 under the action of gravity, and the rods at the end will be stopped by the side of the frame 1, and then the cylinders 2 30 on both sides are started at the same time, so that the two adjustment plates 29 are simultaneously close to the ends of the rods. Under the action of the two adjustment plates 29, the ends of the multiple arranged rods are aligned. Then, according to the diameter of the rods, the motor 3 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 rod at the end of the frame 1. Then, the motor 1 9 drives the rotating shaft 7 to rotate, and the multiple claws 8 rotate at the same time, and use the grooves at their ends to hook the rods at the end of the frame 1. The hooked rods will slide along the upper edges of the claws 8, and the claws 8 and the support The support ring 4 is connected on one side, so that the rod falls into the support ring 4, and then the hydraulic cylinder 11 drives the transmission rod 15 to move horizontally. At the same time, the guide pillars 16 on both sides of the transmission block 36 move in the groove at the bottom of the rotating frame 14, and the rotating frame 14 will rotate due to the push of the guide pillars 16, and the multiple conveying rollers 12 will rise at the same time and contact the bottom of the rod, and then the multiple motors 2 13 will be started at the same time, and the rods will be moved under the rotation of the conveying rollers 12, so that the rods are conveyed to the specified position, and then the pusher claws 8 are reset. The subsequent rods will continue to slide down due to the loss of support until the rod at the end is supported by the frame 1, and then the above operation is repeated, so that multiple rods can be placed in the support ring 4 in turn and conveyed by the conveying rollers 12, thereby eliminating the need for workers to manually place the rods and reducing the labor intensity of workers. In addition, before conveying multiple rods, the ends will be aligned with the cooperation of the two inserting plates 26, and the initial positions will be consistent, which is conducive to improving the subsequent processing accuracy;

[0056] Although the above method can realize the sequential conveying of the bars, 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 piled-up state, thereby affecting the conveying of the bars one by one. Therefore, in order to avoid this situation, after the bars are placed on the frame 1, the cylinder 3 33 is used to drive the pressure rod 34 to descend, so that the pressure rod 34 squeezes the piled-up bars. During the movement of the pressure rod 34, the piled-up bars will move to the periphery due to the squeezing, and move to the gap between the two adjacent bars until the distance between the pressure rod 34 and the bars is equal to the distance between the bars. diameter, at this time, all the bars on the frame 1 will remain 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 accumulation of bars due to collision when they slide down. In addition, the motor five 32 can drive the threaded rod three 31 to rotate to make the transverse plate 5 move laterally, so that the pressure rod 34 does not limit the bars at the end of the frame 1, and does not affect the push of the bar by the pusher claw 8, thereby avoiding the situation where the bars are piled up when they are uniformly placed on the frame 1, thereby affecting the transportation of the bars one by one.

[0057] In this embodiment, Figure 8 and Figure 9 As shown, one side of the threaded block 35 is threadedly connected to the threaded rod 21, both ends of the threaded rod 21 are rotatably set on the fixed plate 19, one end of the fixed plate 19 is fixedly connected to the motor 4 20, and the output end of the motor 4 20 is fixedly connected to one end of the threaded rod 21.

[0058] Two second connecting rods 28 are rotatably provided at the middle of the upper ends of the leftmost and rightmost plug plates 26, and two first connecting rods 27 are rotatably provided at the middle of the upper ends of the remaining plug plates 26. The ends of the second connecting rod 28 are rotatably connected to the ends of the first connecting rod 27, and the ends of two adjacent first connecting rods 27 are rotatably connected.

[0059] One end of the slide rail 24 is fixedly connected to an electric push rod 25 , and a piston end of the electric push rod 25 is fixedly connected to one side of the plug plate 26 .

[0060] Specifically, in the above embodiment, although the bars can be transported sequentially, they need to be arranged obliquely on the frame 1. Since the bars have their own gravity, when they are placed obliquely, gravity will cause them to slide or roll downward. Under the constraint of the frame 1, this tendency will be converted into an extrusion force between the bars. When the bar processing time is long, the time the bar stays on the frame 1 will also be correspondingly longer. When the extrusion force on the bar exceeds its yield strength for a long time, it will cause the bar to deform, thereby affecting the quality of the bar.

[0061] Therefore, in order to solve the above problem, after the bars are arranged obliquely on the frame 1, the electric push rod 25 is started according to the diameter of the bars. The electric push rod 25 drives the plug 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 the two adjacent plugs 26 changes until the distance between the two adjacent plugs 26 is equal to the diameter of the bars. Then, the motor 4 20 drives the threaded rod 21 to rotate, so that the threaded block 35 slides on the slide rod 22 until the plug 26 at the end of the slide rail 24 is aligned with the end of the frame 1. The gap between two adjacent bars is formed by the remaining inserting plates 26. At this time, the cylinder 1 23 drives the slide rail 24 to move downward, so that the multiple inserting plates 26 are inserted into the gap between the two adjacent bars, so that the multiple bars are separated from each other, so that the extrusion force on the bars is reduced, thereby avoiding the situation where the bars stay on the frame 1 for a long time and the extrusion force on the bars exceeds their yield strength for a long time, thereby causing the bars to deform and affecting their quality. In addition, the transportation of the bars at the end of the frame 1 is not affected.

[0062] When the rod at the end of the frame 1 moves onto the support ring 4, the slide rail 24 is driven up again, and the insert plate 26 is moved away from the rod, causing the rod to slide down again, and then the insert plate 26 is driven again to be inserted between two adjacent rods, and the cycle is repeated.

[0063] Working principle: multiple rods 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 surface, the rods will slide toward the side of the frame 1 under the action of gravity, and the rod at the end will be stopped by the side of the frame 1, and then the cylinders 2 30 on both sides are started at the same time, so that the two adjustment plates 29 are close to the ends of the rods at the same time. Under the action of the two adjustment plates 29, the ends of the multiple arranged rods are aligned, and then according to the diameter of the rods, the motor 3 17 drives the threaded rod 18 to rotate, and adjusts the distance between the connecting plate 6 and the frame 1 until the end of the claw 8 is located below the rod at the end of the frame 1, and then the motor 1 9 drives the rotating shaft 7 to rotate, so that multiple claws 8 rotate at the same time, and use the grooves at their ends to move the claws 8 located at the end of the frame 1. The rod at the end of the frame 1 is hooked up, and the hooked rod 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 rod falls into the support ring 4, and then the hydraulic cylinder 11 drives the transmission rod 15 to move horizontally. At the same time, the guide columns 16 on both sides of the transmission block 36 move in the groove at the bottom of the rotating frame 14, and the rotating frame 14 will rotate due to the push of the guide columns 16, and then multiple conveying rollers 12 will rise at the same time and contact the bottom of the rod, and then start multiple motors 2 13 at the same time, and move the rod under the rotation of the conveying roller 12, so that the rod is conveyed to the specified position, and then the claw 8 is reset, and the subsequent rods will continue to slide due to the loss of support until the rod at the end is supported by the frame 1, and then repeat the above operation to make multiple rods The bars are sequentially placed in the support ring 4 and transported by the transport roller 12, thereby eliminating the need for workers to manually place the bars and reducing the labor intensity of the workers. In addition, before multiple bars are transported, the ends are aligned with the cooperation of the two insert plates 26, and the initial positions are kept consistent, which is beneficial to improving the subsequent processing accuracy. Although the above method can realize the sequential transportation of the bars, 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 piled-up state, thereby affecting the transportation of the bars one by one. Therefore, in order to avoid this situation, after the bars are placed on the frame 1, the cylinder 3 33 can be used to drive the pressure rod 34 to descend, so that the pressure rod 34 squeezes the piled-up bars. During the movement of the pressure rod 34 The stacked bars will move toward the periphery due to being squeezed, and move into the gap between two adjacent bars until the distance between the pressure rod 34 and the bars is equal to the diameter of the bars. At this time, all the bars on the frame 1 will remain in an arranged state due to being limited by the pressure rod 34, and when the subsequent bars slide off, the pressure rod 34 will always limit the bars, and there will be no accumulation of bars due to collision when they slide off. In addition, the transverse plate 5 can be moved transversely by driving the threaded rod 31 to rotate by the motor 5 32, so that the pressure rod 34 does not limit the bars at the end of the frame 1, and does not affect the pushing of the bars by the pusher claw 8, thereby avoiding the situation where the bars are piled up when they are uniformly placed on the frame 1, thereby affecting the transportation of the bars one by one.After the bars are arranged obliquely on the frame 1, the electric push rod 25 is started according to the diameter of the bars. The electric push rod 25 drives the plug 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 the two adjacent plug plates 26 changes until the distance between the two adjacent plug plates 26 is equal to the diameter of the bars. Then, the motor 4 20 drives the threaded rod 21 to rotate, so that the threaded block 35 slides on the slide rod 22 until the plug plate 26 at the end of the slide rail 24 is aligned with the gap between the two adjacent bars at the end of the frame 1, and the remaining plug plates 26 are also aligned with the gap between the two adjacent bars. At this time, the cylinder 1 23 drives the slide rail 24 to The slide rail 24 moves downward, so that the multiple insert plates 26 are inserted into the gaps between two adjacent bars, so that the multiple bars are separated from each other, and the extrusion pressure on the bars is reduced, thereby avoiding the situation where the bars stay on the frame 1 for a long time, and the extrusion pressure on the bars exceeds their yield strength for a long time, thereby causing the bars to deform and affect their quality. In addition, it does not affect the transportation of the bars at the end of the frame 1. When the bars at the end of the frame 1 move to the support ring 4, the slide rail 24 is driven up again, and the insert plates 26 are moved away from the bars, causing the bars to slide down again. Then, the insert plates 26 are driven again to be inserted between the two adjacent bars, and the cycle is repeated.
