Description

Technical Field

[0001] The utility model relates to a steel divider for bar counting equipment, belonging to the technical field of metallurgical bar counting equipment. Background Art

[0002] In the bar finishing process area, as the bar counting equipment becomes automated, it is required that after the fixed-length threaded steel bars reach a certain number, a certain distance be opened between the bars to facilitate bundling of the counted bars, so that they can fall quickly and accurately into the fixed-length bundling slots of a specified length to complete the bar bundle alignment. This ensures that the ends of each bundle of bars are neat and achieves the required packaging quality.

[0003] The incoming and outgoing arms of the current bar counters are fixed. When they are raised to separate the bars, they rub against the threads of the rebar bars, causing them to move in the opposite direction and prevent them from falling into the fixed-length bundle slots. The solution is to install a reverse alignment device at the end of the bar divider. After the divider completes the separation, the reverse alignment device activates and pushes the finished bars back into their original position. This increases the separation time for each bundle of bars by 20%, which is not conducive to improving production efficiency. Furthermore, the fixed incoming and outgoing arms cannot be adjusted to the specific product specifications and production pace. On the one hand, the separation distance may be too small, resulting in incomplete separation, with the later bundle of rebar falling into the completed earlier bundle, making it impossible to effectively guarantee the quantity of bars in each bundle and causing quality issues. On the other hand, the separation distance may be too large, resulting in inconsistent production connections and slowing down the production pace. Therefore, it is necessary to improve the existing bar counters' separation devices. Utility Model Content

DETAILED DESCRIPTION

[0015] The utility model is composed of a lifting shaft 1, a steel dividing shaft 2, a steel supply arm 3, a steel supply roller 5, a steel dividing arm 6, a steel dividing arm rotating shaft 7, a steel dividing roller 9, a large adjustment push rod 12, a small adjustment push rod 13, and a guide shield 19.

[0016] The figure shows that the lifting shaft 1 is a long, horizontal shaft, with both ends mounted on the upper ends of the steel splitting lifting bracket. A steel splitting center shaft 2 is vertically welded to the upper portion of the lifting shaft 1. A steel feed arm 3 and a steel splitting arm 4 are mounted on either side of the steel splitting center shaft 2. The steel feed arm 3 is fixedly connected to the steel splitting center shaft, while the steel splitting arm 6 is rotatably connected to the steel splitting center shaft 2.

[0017] The figure shows that one side of the upper end of the steel splitting center axis 2 is welded to the upper end of the steel arm 3, and the lower end of the steel arm 3 is welded to one end of the lifting shaft 1. The steel splitting arm rotating shaft 7 is installed on the other side of the upper end of the steel splitting center axis 2, and the upper end of the steel splitting arm 6 is connected to the steel splitting arm rotating shaft 7. The lower end of the steel splitting arm 6 is suspended in the air, and the steel splitting arm 6 can rotate around the steel splitting arm rotating shaft 7. The lower part of the steel splitting arm 6 is connected to the upper end of the large adjustment push rod 12 and the small adjustment push rod 13, and the lower ends of the large adjustment push rod 12 and the small adjustment push rod 13 are connected to the upper surface of the lifting shaft 1. The length of the large adjustment push rod 12 and the small adjustment push rod 13 can be adjusted to support the steel splitting arm 6 when it rotates to different angles.

[0018] The figure shows that the outer sides of the steel arm 3 and the steel splitting arm 6 are respectively installed with a steel roller 5 and a steel splitting roller 9. The installation structure of the steel roller 5 and the steel splitting roller 9 is as follows: the two ends of the steel arm 3 and the steel splitting arm 6 are respectively welded with a vertical fixed plate 10, the center of which has an axial hole, and the two ends of the steel core shaft 4 and the steel splitting core shaft 8 are respectively threaded. The two ends of the steel core shaft 4 and the steel splitting core shaft 8 pass through the axial holes of the fixed plates 10 at the two ends of the steel arm 3 and the steel splitting arm 6 respectively and are fixedly connected by nuts; the two ends of the steel core shaft 4 and the steel splitting core shaft 8 are respectively fixed with tapered roller bearings 11, the steel roller 5 and the steel splitting roller 9 are respectively sleeved on the steel core shaft 4 and the steel splitting core shaft 8, and the inner walls of the steel roller 5 and the steel splitting roller 9 are respectively connected with the tapered roller bearings 11. The incoming steel roller 5 and the separating steel roller 9 can rotate around the tapered roller bearings 11 respectively. When the outer wall of the threaded steel bar contacts the incoming steel roller 5 and the separating steel roller 9, the friction between the rollers and the threaded steel bar is eliminated due to the rotation of the rollers.

[0019] The figure shows that the incoming roller 5 and the distributing roller 9 are tapered rollers. The upper diameter of the incoming roller 5 and the distributing roller 9 is larger than the lower diameter. Accordingly, the diameter of the tapered roller bearings 11 mounted on the upper ends of the incoming roller 5 and the distributing roller 9 is larger than the diameter of the tapered roller bearings 11 mounted on the lower ends of the incoming roller 5 and the distributing roller 9. Taper is the ratio of the difference between the upper and lower diameters of a roller to the roller length. In one embodiment of the present invention, the taper of the incoming roller 5 is 1:400, and the taper of the distributing roller 9 is 1:600. The tapered structure of the incoming roller 5 and the distributing roller 9 ensures smoother rolling of the rebar along the rollers.

[0020] The figure shows that the large adjustment rod 12 and the small adjustment rod 13 are located below the middle and lower parts of the steel splitter arm 6, respectively. The large adjustment rod 12 and the small adjustment rod 13 each consist of an upper sleeve 14, a lower sleeve 15, and an adjustment screw 16. The inner walls of the upper sleeve 14 and lower sleeve 15 have threads with opposite rotations. The ends of the adjustment screw 16 have threads that match the threads of the upper sleeve 14 and lower sleeve 15, respectively. The ends of the adjustment screw 16 are threadedly connected to the upper sleeve 14 and lower sleeve 15, respectively. A rotating hexagonal ring 17 is welded to the middle of the adjustment screw 16. The upper ends of the upper sleeve 14 of the large adjustment rod and the small adjustment rod 13 are respectively welded to the lower surface of the steel splitter arm 6. The lower ends of the lower sleeve 15 of the large adjustment rod 12 and the small adjustment rod 13 are respectively connected to the lifting shaft 1 via rollers 18. When the steel arm 6 is lifted or lowered, the lower ends of the large adjustment push rod 12 and the small adjustment push rod 13 connected to the steel arm 6 will slide along the plane of the lifting shaft 1. The use of the roller 18 can reduce the sliding friction.

[0021] When the length of the large adjusting push rod 12 and the small adjusting push rod 13 needs to be adjusted, the rotating hexagon 17 is rotated with a wrench, and the adjusting screw 16 is rotated. The adjusting screw 16 drives the upper sleeve 14 and the lower sleeve 15 to move toward the middle or both ends at the same time by rotating the threads in opposite directions, thereby achieving the purpose of adjusting the length of the large adjusting push rod 12 and the small adjusting push rod 13.

[0022] The figure shows a guide shield 19 fixed to the top of the steel-splitting axis 2. This shield covers the incoming and outgoing steel arms 3 and 6 on either side of the upper end of the axis 2. The ends of the shield 19 are tilted downward. The shield 9 effectively guides the rebar to be separated toward the incoming and outgoing steel arms 3 and 6, preventing the upper ends of the incoming and outgoing steel arms 3 and 6 from becoming stuck.

[0023] The use process of this utility model is as follows:

[0024] The utility model uses a lifting shaft 1 as a positioning core rod, which is installed under the top plane of the chain. A group of steel separating devices is installed at the interval between each pair of chain beams. The steel separating devices installed in groups rise in sequence from near to far to separate the threaded steel bars on the chain bed.

[0025] The two ends of the lifting shaft 1 are fixed on the bracket. When the steel dividing device of the bar counter is dividing the steel, the cylinder provides power to lift the lifting shaft 1 of the steel dividing device, and the threaded steel laid flat on the chain bed will use the steel dividing center axis 2 of the steel dividing device as the axis to separate the threaded steel to the incoming steel side and the dividing steel side. Since the incoming steel arm 3 and the dividing steel arm 6 are respectively equipped with rotatable incoming steel rollers 5 and dividing steel rollers 9, the original sliding friction between the raised incoming steel arm 3 and the dividing steel arm 6 and the threaded steel is converted into rolling friction, the friction force is greatly reduced, and the threaded steel no longer moves in the length direction, which facilitates the front bundle to move quickly into the fixed-length bundle groove.

[0026] The steel dividing arm 6 can adjust the opening angle by changing the length of the large adjustment rod 12 and the small adjustment rod 13. The angle of the steel dividing arm 6 can be adjusted according to the change of the chain transmission speed. Generally, the farthest angle is increased to ensure that the bar can accurately fall into the fixed-length bundle groove.
