[0026] As Figures 1 to 4 shown, the steel bar feeding device of this embodiment includes a hopper 1. One side of the hopper 1 is provided with a discharge channel 3, and a conveying mechanism 2 for conveying the steel bar 9 to the discharge channel 3 is provided below. The conveying mechanism 2 includes a plurality of conveying wheels 21, and each conveying wheel 21 is connected with a rotation driving member.

[0027] In the steel bar mesh production line, the steel bar feeding device of this embodiment is arranged between the steel bar straightening and cutting machine and the steel bar mesh welding machine. The steel bar straightening and cutting machine straightens and cuts the steel bar coil, and the cut steel bar 9 falls into the hopper 1. The steel bar 9 at the lowest layer of the hopper 1 contacts the conveying wheel 21, and the rotation driving member (not shown in the figure, such as a motor, a hydraulic motor, etc.) drives the conveying wheel 21 to rotate, driving the steel bar 9 at the lowest layer of the hopper 1 to move towards the discharge channel 3, and feeding through the discharge channel 3 to the steel bar mesh welding machine for welding. For the steel bar feeding device of this embodiment, when the feeding and discharging speeds of the upstream steel bar straightening and cutting machine and the downstream steel bar mesh welding machine are inconsistent, the hopper 1 can store materials to prevent shutdown and waiting, and has good working continuity; by setting the conveying mechanism 2, a plurality of conveying wheels 21 convey the steel bar 9 and discharge it along the discharge channel 3, with a simple structure, time and labor saving, and high automation degree.

[0028] In this embodiment, each conveying wheel 21 is connected to a rotary driving member, and the driving force is large, so that a driving force can be continuously obtained during the discharging process of the steel bar 9. Of course, in other embodiments, some of the conveying wheels 21 may be connected to the rotary driving member, and the other conveying wheels 21 are driven wheels, with a simpler structure and lower cost, but the discharging effect is somewhat reduced.

[0029] As Figure 3 shown, in this embodiment, the height of the discharging channel 3 is h, satisfying d < h < 2d, where d is the diameter of the steel bar 9. The height of the discharging channel 3 is greater than the diameter of one steel bar 9 and less than the diameter of two steel bars 9, which can ensure that only the steel bar 9 at the lowermost layer of the hopper 1 can enter the discharging channel 3 for discharging each time. When the steel bar 9 at the lowermost layer of the hopper 1 is discharged, it can prevent the steel bar 9 at the upper layer from also entering the discharging channel 3, causing discharging chaos and blockage, and the discharging is smooth.

[0030] As Figure 2 shown, in this embodiment, the width of the discharging channel 3 is w, satisfying d < w < 2d. The height and width of the discharging channel 3 are both greater than the diameter of one steel bar 9 and less than the diameter of two steel bars 9, which can ensure that only one steel bar 9 at the lowermost layer of the hopper 1 can enter the discharging channel 3 for discharging each time, preventing blockage when the steel bar 9 in the hopper 1 is discharged, and the discharging is smoother.

[0031] Furthermore, in this embodiment, a guiding portion 4 is provided above one end of the discharging channel 3 close to the hopper 1, and the height of the guiding portion 4 gradually decreases along the discharging direction of the discharging channel 3. As Figure 3 shown by the arrow in, the discharging direction is from right to left. The gradually decreasing height of the guiding portion 4 guides the steel bar 9, with a simple structure and good guiding effect. Since the discharging channel 3 can only accommodate one steel bar 9 for discharging, the passing space is small, and the inclined surface of the hopper 1 is inclined inward. If the guiding portion 4 is not provided and the steel bar 9 is directly conveyed from the hopper 1 to the discharging channel 3, the steel bar 9 is easily blocked by the hopper 1, resulting in failure to discharge; at the same time, the steel bar 9 may be slightly bent. By providing the guiding portion 4 to guide the steel bar 9, it can prevent the steel bar 9 with a large bend from blocking the discharging channel 3, with better reliability and smoother discharging.

[0032] Further, in this embodiment, a discharge chute 5 with an opening facing downward is provided on one side of the hopper 1. The height of the discharge channel 3 is formed between the top plate 51 of the discharge chute 5 and the vertex of the conveying wheel 21, and the width of the discharge channel 3 is formed between the two side plates 52 of the discharge chute 5. The guiding portion 4 is provided on the top plate 51. That is, the distance between the two side plates 52 of the discharge chute 5 is equal to the width w of the discharge channel 3, and the distance between the top plate 51 of the discharge chute 5 and the vertex of the conveying wheel 21 is equal to the height h of the discharge channel 3. When discharging, the two side plates 52 of the discharge chute 5 limit the steel bars 9 to prevent the steel bars 9 from shifting; the top plate 51 of the discharge chute 5 and the conveying wheel 21 cooperate up and down to discharge the steel bars 9, and the structure is simple and reliable.

[0033] Further, in this embodiment, the discharge chute 5 is detachably connected to the hopper 1 (for example, detachably connected by bolts, screws, etc.), which is convenient for replacing the guiding portion 4 and the discharge chute 5 to adapt to the discharge of steel bars 9 with different diameters.

[0034] Further, in this embodiment, the conveying mechanism 2 further includes a mounting frame 22 for mounting the conveying wheel 21 and a lifting driving member 23 connected to the mounting frame 22. A plurality of conveying wheels 21 are provided and are all connected with a rotation driving member. The lifting driving member 23 drives the plurality of conveying wheels 21 to rise or fall simultaneously, which can adjust the height of the discharge channel 3 to adapt to the discharge of steel bars 9 with different diameters, and the operation is simple and reliable. Among them, the lifting driving member 23 can be an oil cylinder, a cylinder or an electric push rod, etc.

[0035] Further, in this embodiment, the cross-section and longitudinal section of the upper part of the hopper 1 are both trapezoidal in reverse, and the cross-section and longitudinal section of the lower part of the hopper 1 are both rectangular. The discharge channel 3 communicates with the lower part of the hopper 1. The trapezoidal hopper 1 is large at the top and small at the bottom, which is convenient for discharging and collecting the steel bars 9; the cross-section and longitudinal section of the lower part of the hopper 1 are both rectangular, so that the steel bars 9 in the lower layer of the hopper 1 are evenly arranged, which is convenient for discharging. Preferably, the width of the rectangle of the cross-section of the lower part of the hopper 1 is greater than the diameter of one steel bar 9 and less than the diameter of two steel bars 9, so that only one steel bar 9 can fall on the conveying wheel 21 for conveying at the same time, preventing chaotic discharge and blockage, and the discharge is smoother. Among them, the length direction of the steel bar 9 is defined as the longitudinal direction, and the transverse direction is perpendicular to the longitudinal direction.

[0036] Further, in this embodiment, the conveying wheel 21 is provided with anti-slip lines (not shown in the figure). The anti-slip lines can increase the friction between the conveying wheel 21 and the steel bars 9, prevent slipping, and have higher conveying efficiency and better reliability.

[0037] Further, in this embodiment, a vibrator 6 is provided on the hopper 1. The vibrator 6 vibrates the steel bars 9 in the hopper 1 to prevent the steel bars 9 from accumulating and blocking in the hopper 1, improving the blanking efficiency; it can also prevent a large amount of the steel bars 9 in the hopper 1 from falling instantaneously after accumulating to a certain extent, generating an impact and damaging the conveying wheel 21.

[0038] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible changes and modifications to the technical solution of the present invention by using the methods and technical contents disclosed above, or modify it into an equivalent embodiment with equivalent changes. Therefore, any simple modification, equivalent replacement, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention still fall within the scope of the protection of the technical solution of the present invention.
