DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-6The utility model provides an embodiment: a rod material clamping and conveying device, including a clamping and conveying device 1 and a screening device 2, the screening device 2 is arranged on the clamping and conveying device 1, the clamping and conveying device 1 includes a supporting frame 3, a fixing frame 4, a motor 5, a fixing plate 6, a limiting plate 7, a rotating wheel 8, a clamping and conveying groove 9, a rod material 10 and a conveyor belt 11, the fixing plate 6 is symmetrically arranged, and one side of the fixing plate 6 is fixedly connected to the inner end of the supporting frame 3, the fixing frame 4 is fixedly connected to the side of the fixing plate 6 close to the supporting frame 3, the motor 5 is fixedly installed on the fixing frame 4, both ends of the limiting plate 7 are fixedly connected to the inner end of the supporting frame 3, both ends of the rotating wheel 8 are rotatably connected to the two fixing plates 6 through a rotating shaft, the clamping and conveying groove 9 is evenly penetrated and opened on the outer side of the rotating wheel 8, and the conveyor belt 11 is arranged on one side of the supporting frame 3.

[0021] The screening device 2 includes a screening box 12, a rod material bin 13, a screening pipe 14, a receiving plate 15, a slide plate 16, a stop bar 17, a screening trough 18 and a feeding trough 19. The rod material bin 13 is arranged inside the screening box 12, the screening pipe 14 is fixedly connected to one end of the screening box 12, both ends of the receiving plate 15 are fixedly connected to the inner end of the screening box 12, the bottom end of the slide plate 16 is fixedly connected to the top of the screening box 12, the stop bar 17 is symmetrically fixedly connected to the top of the slide plate 16, the screening trough 18 is opened through the slide plate 16, and the feeding trough 19 is opened through the bottom end of the screening box 12.

[0022] The bottom end of the screening box 12 is fixedly connected to the top ends of the two fixed plates 6, and the bottom end of the screening box 12 is fixedly connected to the top ends of the limiting plates 7. The portion of the rotating wheel 8 leaking out of the fixed plates 6 is located inside the screening box 12, and the loading trough 19 is located directly above the rotating wheel 8. When the rod material 10 falls into the screening box 12, it is located above the rotating wheel 8.

[0023] The limiting plate 7 is designed to be arc-shaped, and the inner side of the limiting plate 7 matches the outer side of the rotating wheel 8. The bottom end of the limiting plate 7 is higher than the bottom end of the rotating wheel 8. When the opening of the clamping groove 9 rotates to the bottom, the opening of the clamping groove 9 is completely separated from the inner end of the limiting plate 7, which facilitates the rod 10 to separate from the clamping groove 9 and fall to the top of the conveyor belt 11.

[0024] The driving end of the motor 5 is fixedly connected to one end of the rotating wheel 8. The rotating wheel 8 is driven by the motor 5 to rotate. When the rotating wheel 8 rotates, the rod 10 is clamped by the clamping groove 9 and evenly transported to the conveyor belt 11.

[0025] The receiving plate 15 is located directly below the screening groove 18, and the width of the screening groove 18 is slightly larger than the diameter of the rod 10, and one-third of the length of the rod 10 is larger than the diameter of the rod 10. If the length of the rod 10 is not enough, it will not be able to pass through the screening groove 18 for screening. Therefore, the size of the rod 10 screened by the screening device 2 needs to be limited.

[0026] Working principle: During use, first place a recycling box under the screening tube 14, then start the motor 5, the driving end of the motor 5 drives the rotating wheel 8 to rotate, the rotating wheel 8 rotates from the top of the rotating wheel 8 to the top of the limiting plate 7, and the rod 10 is transported to the slide plate 16 to slide downward. When the vertically sliding rod 10 slides to the screening slot 18, since the length of the rod 10 is much greater than the width of the screening slot 18, the center of gravity of the rod 10 is still on the slide plate 16, so that the rod 10 will slide through the top of the screening slot 18 and enter the screening tube 14, and then fall into the recycling box through the screening tube 14. When the horizontally rolling rod 10 rolls to the screening slot 18, it loses support and falls downward under the action of gravity. The top of the receiving plate 15, the bar 10 rolls downward through the receiving plate 15 until it leaves the receiving plate 15, and the bar 10 falls to the top of the rotating wheel 8 under the action of gravity. Due to the continuous rotation of the rotating wheel 8, the clamping groove 9 opened on the rotating wheel 8 is driven to rotate. When the opening of the clamping groove 9 faces upward, the bar 10 rolls and falls into the clamping groove 9 and rotates together with the clamping groove 9. When the opening of the rotating clamping groove 9 tilts downward, the bar 10 is blocked by the inner wall of the limit plate 7, so that the bar 10 is stuck in the clamping groove 9. When the opening of the clamping groove 9 leaves the limit plate 7, the bar 10 loses support and falls to the top of the conveyor belt 11 under the action of gravity. The moving conveyor belt 11 transports the bar 10 to the next processing area.
