Description

Technical Field

[0001] This utility model relates to the technical field of steel strapping machines, and more specifically, it relates to a rapid steel strapping machine. Background Technology

[0002] Steel strapping machines are commonly used packaging machinery, primarily for non-ferrous metal and steel companies to bundle various specifications of pipes, profiles, ingots, plates, and other products. A steel strapping machine typically consists of a conveying section and a strapping section. The conveying section is responsible for smoothly and accurately moving the plates or pipes to be bundled to the strapping station; the strapping section is responsible for tightly binding the steel straps around the stack of plates or bundles of pipes, completing the strapping operation.

[0003] However, while the conveyor section of existing packaging machines has basic movement functions and can transport sheet metal and pipes on the production line, it still has the following significant shortcomings in practical applications: 1. When handling stacked heavy steel plates, existing baling equipment often causes the plates to deviate from the conveyor centerline. This forces operators to rely on lifting equipment for frequent manual adjustments, a cumbersome and time-consuming process that severely hinders baling efficiency. Furthermore, the accuracy of manual positioning is difficult to guarantee, easily leading to uneven stress on the baling straps, creating stress concentration points, and significantly increasing the risk of strap breakage during subsequent transportation.

[0004] 2. During the manual adjustment of the steel plate position, the steel plate is prone to uncontrolled lateral sliding on the conveyor rollers. This hard friction will cause severe scratching and wear on the surface of the conveyor rollers. After the rollers wear out, their conveying accuracy and stability will drop sharply, directly causing the steel plate to fail to stop accurately and reliably at the preset packaging station.

[0005] 3. Steel plate packaging requires neat stacking edges to avoid unevenness affecting the uniform stress on the steel straps. However, existing equipment lacks automatic stacking edge correction functionality. Before packaging, the stacking edges must be manually aligned. Due to the tight stacking of steel plates and the large weight of each piece, this operation is extremely laborious and difficult, requiring multiple people to work together and spending a lot of time on repeated adjustments, becoming a key bottleneck restricting packaging efficiency.

[0006] Therefore, in view of the problems existing in the existing equipment, there is an urgent need to develop a steel strapping machine. Utility Model Content

[0007] In view of the problems existing in the prior art, this utility model provides a steel strapping machine for rapid packaging, so as to solve the technical problems mentioned in the background art.

[0008] Technical solution

[0009] To achieve the above objectives, this utility model provides the following technical solution: a steel strip rapid baling machine, comprising support legs, a fixed frame fixedly connected to the support legs, driven rollers of equal spacing rotatably connected to the fixed frame, multiple horizontal plates fixedly connected to the lower side of the fixed frame, two hydraulic push rods fixedly connected to the horizontal plates, a fixed plate fixedly connected to the telescopic end of the hydraulic push rods, an equally spaced driving roller rotatably connected to the upper side of the fixed plate, four guide plates provided in the fixed frame, a support plate slidably connected between the four guide plates, a hydraulic push rod fixedly connected to the guide plates, the telescopic end of the hydraulic push rod fixedly connected to the support plate, two guide rails fixedly connected to the lower side of the support plate, a sliding plate slidably connected to the two guide rails, an equally spaced compression roller rotatably connected to the sliding plate, and an alignment structure provided on the upper side of the support plate.

[0010] The present invention is further configured such that the driven roller and the driving roller are arranged alternately, and the driving roller is driven by a motor.

[0011] The present invention is further configured such that the support plate is fixedly connected to two hydraulic push rods three, and the telescopic ends of the hydraulic push rods three are fixedly connected to the adjacent sliding plate one through a connector.

[0012] The present invention is further configured such that the alignment structure includes two vertical baffles, the two vertical baffles are fixedly connected to the left side of the support plate, a second fixing plate is fixedly connected to the upper side of the support plate, a second sliding plate is slidably connected to the second fixing plate, a second sliding plate is splinedly connected to the second sliding plate, and a compression plate is fixedly connected to the second splined plate.

[0013] The present invention is further configured such that a T-shaped groove is provided on the upper side of the second fixed plate, and the second sliding plate is slidably connected in the T-shaped groove of the second fixed plate.

[0014] The present invention is further configured such that a roller is rotatably connected to the lower side of the extrusion plate, and a hydraulic push rod four is fixedly connected to the upper side of the support plate, with the telescopic end of the hydraulic push rod four being fixedly connected to the sliding plate two. Beneficial effects

[0015] Compared with the prior art, this utility model provides a steel strapping rapid packaging machine, which has the following beneficial effects: This invention uses the telescopic ends of two hydraulic push rods to move adjacent sliding plates. The two sliding plates move closer to each other along the guide rail, and the sliding plates drive the pressing rollers on them to press the front and rear sides of the steel plate, thereby keeping the front and rear sides of the steel plate aligned. This allows for centering and correction of the stacked steel plates, ensuring that the stacked steel plates are in the middle of the fixed frame. This avoids the need for manual adjustment of the steel plates using lifting equipment, improves the centering and correction efficiency of the steel plates, and increases the packing efficiency of the packing machine for stacked steel plates.

[0016] This invention uses a hydraulic push rod to drive a fixed plate and its active roller downwards. The active roller loses contact with the lower side of the steel plate, thus avoiding hard friction between the steel plate and the active roller during the centering adjustment of the steel plate. This ensures the conveying accuracy of the baling machine, allowing the steel plate to move accurately to the baling station and ensuring that the spacing between the baling steel strips is the same.

[0017] This invention uses the telescopic end of the hydraulic push rod four to move the sliding plate two to the left. The sliding plate two, through the spline rod, moves the extrusion plate to the left, thereby extruding the right side of the steel plate. Because the two vertical baffles limit the left side of the steel plate, the extrusion plate extrudes the steel plate to the left, making the left and right sides of the steel plate flush. This achieves a quick and neat edge arrangement of the stacked steel plates, thereby improving the packing efficiency of the steel plates and reducing the impact on subsequent transportation of the steel plates.

[0023] Please see Figures 1-7 A steel strip rapid baling machine includes support legs 1, a fixed frame 2 fixedly connected to the support legs 1, driven rollers 3 evenly spaced and rotatably connected to the fixed frame 2, multiple horizontal plates 4 fixedly connected to the lower side of the fixed frame 2, two hydraulic push rods 5 fixedly connected to the horizontal plates 4, a fixed plate 6 fixedly connected to the telescopic end of the hydraulic push rods 5, and equally spaced driving rollers 7 rotatably connected to the upper side of the fixed plate 6. The fixed frame 2 is provided with four guide plates 8, and support plates 9 are slidably connected between the four guide plates 8. Hydraulic push rods are fixedly connected to the guide plates 8. 2.10, the telescopic end of the hydraulic push rod 2.10 is fixedly connected to the support plate 9. Two guide rails 11 are fixedly connected to the lower side of the support plate 9. The two guide rails 11 are slidably connected to a sliding plate 12. The sliding plate 12 is rotatably connected to equally spaced extrusion rollers 13. An alignment structure is provided on the upper side of the support plate 9. The driven rollers 3 and the driving rollers 7 are arranged alternately, and the driving rollers 7 are all driven by a motor. Two hydraulic push rods 3.14 are fixedly connected to the support plate 9. The telescopic end of the hydraulic push rod 3.14 is fixedly connected to the adjacent sliding plate 12 through a connector.

[0024] Please see Figure 4 and Figure 7 The alignment structure includes two vertical baffles 15, which are fixed to the left side of the support plate 9. A second fixed plate 16 is fixed to the upper side of the support plate 9. A second sliding plate 17 is slidably connected to the second fixed plate 16. A spline rod 18 is splined to the second sliding plate 17. A pressing plate 19 is fixed to the spline rod 18. A T-shaped groove is provided on the upper side of the second fixed plate 16. The second sliding plate 17 is slidably connected to the T-shaped groove of the second fixed plate 16. A roller 20 is rotatably connected to the lower side of the pressing plate 19. A hydraulic push rod 21 is fixed to the upper side of the support plate 9. The telescopic end of the hydraulic push rod 21 is fixed to the second sliding plate 17.

[0025] Working principle: The worker places the stacked steel plates on top of the driven roller 3 and the driving roller 7. Then, the worker starts the driving roller 7, which uses friction to move the stacked steel plates to the left to pack them. During the leftward movement, the worker activates hydraulic push rod 2 10, which moves the support plate 9 downward along the four guide plates 8. The support plate 9 then moves all the parts on it downward. When the two vertical baffles 15 are inserted between the driven roller 3 and the driving roller 7, the worker closes hydraulic push rod 2 10. The driving roller 7 then moves the steel plates to the left until the left side of the steel plates contacts the two vertical baffles 15. Finally, the worker closes the driving roller 7. Start hydraulic push rod 5. Hydraulic push rod 5 drives fixed plate 6 and its drive roller 7 to move downward. Drive roller 7 loses contact with the lower side of steel plate. As steel plate moves to the left, support plate 9 moves downward. Support plate 9 drives sliding plate 17 to move downward through fixed plate 16. At the same time, roller 20 contacts steel plate. Support plate 9 continues to move downward. Extrusion plate 19 and spline rod 18 stop moving downward. Spline rod 18 then slides relative to sliding plate 17. As steel plate moves to the left, after roller 20 loses contact with steel plate, extrusion plate 19 drives spline rod 18 to move downward, so that extrusion plate 19 is located on the right side of steel plate.

[0026] First, the hydraulic push rod 314 is activated. The telescopic ends of the two hydraulic push rods 314 drive the adjacent sliding plate 12 to move. The two sliding plates 12 move closer to each other along the guide rail 11. The sliding plate 12 drives the extrusion roller 13 on it to extrude the front and rear sides of the steel plate, thereby keeping the front and rear sides of the steel plate aligned. The steel plate is located in the middle of the driven roller 3. Then, the hydraulic push rod 421 is activated. The telescopic end of the hydraulic push rod 421 drives the sliding plate 21 to move to the left. The sliding plate 21 drives the extrusion plate 19 to move to the left through the spline rod 18, thereby extruding the right side of the steel plate. Since the two vertical baffles 15 limit the left side of the steel plate, the extrusion plate 19 extrudes the steel plate to the left, making the left and right sides of the steel plate flush.

[0027] After the steel plate is adjusted, the support plate 9 and its parts are reset by controlling hydraulic push rod 210, hydraulic push rod 314 and hydraulic push rod 421. Hydraulic push rod 15 is activated to move the drive roller 7 upward to reset and activate the drive roller 7. The drive roller 7 drives the steel plate to continue to move to the left and then the steel plate is packaged.
