This method has high labor costs, inconsistent neatness, low stacking efficiency, and certain safety hazards. Therefore, there is an urgent need for an improved technology to solve this problem in the existing technology. Utility Model Content

[0025] Please see Figure 1-5 This utility model provides a technical solution: a stacking machine for small bundles of C-shaped steel, including a frame, an upper material support mechanism, a lower material support mechanism and a limiting mechanism;

[0026] The frame includes a base frame 1, uprights 2, crossbeams 3, connecting beams 4 and extension frame 5. Two uprights 2 are symmetrically arranged on the upper surface of the base frame 1. Each of the two uprights 2 has a crossbeam 3 at its top. A connecting beam 4 is arranged between the tops of the two crossbeams 3. An extension frame 5 is arranged on one side of the connecting beam 4. A first guide frame 6 is arranged on the upper surface of the crossbeam 3 and at the position of the connecting beam 4 via a support platform 17.

[0027] The upper material support mechanism includes a fixed beam 7, an upper support plate 8, and a first cylinder 9. The fixed beam 7 is connected to the crossbeam 3 at the connection point with the column 2. The fixed beam 7 is provided with several second guide frames 10. The upper support plate 8 is movably arranged inside the second guide frame 10. The upper support plate 8 slides with the second guide frame 10 through a third linear guide rail 32 to ensure that the upper support plate 8 slides stably along the second guide frame 10. The bottom of the second guide frame 10 is provided with a first cylinder 9. The piston rod of the first cylinder 9 is connected to one end of the upper support plate 8.

[0028] The lower support mechanism includes a first bidirectional shaft reducer 11, a first connecting rod 12, a lifting upright 13, a lifting crossbar 14, a lower support plate 15, and a second cylinder 16. The output shaft of the first bidirectional shaft reducer 11 faces both sides and is respectively connected to the first connecting rod 12. The first connecting rod 12 is supported by bearing seats set on the upper surface of the support platform 17 and the connecting beam 4. A first gear 18 is installed on the outer end of the first connecting rod 12. There are two lifting uprights 13, which are respectively guided and engaged with the first guide frame 6. The two sides of the lifting upright 13 are slidably engaged with the first guide frame 6 through the second linear guide rails 31 to ensure the lifting... The lowering pole 13 slides stably along the first guide frame 6. The bottom of both lifting poles 13 is connected to the lifting crossbar 14. The inner side of the lifting pole 13 meshes with the first gear 18 through the first rack 19. The lifting crossbar 14 is provided with several third guide frames 20. The lower end support plate 15 is movably arranged in the third guide frame 20. The lower end support plate 15 slides with the third guide frame 20 through the fourth linear guide rail 33 to ensure that the lower end support plate 15 slides stably along the third guide frame 20. The bottom of the third guide frame 20 is provided with a second cylinder 16. The piston rod of the second cylinder 16 is connected to one end of the lower end support plate 15.

[0029] The limiting mechanism includes a second bidirectional shaft reducer 21, a second connecting rod 22, a slide table 23, a translation crossbar 24, a baffle 25, and a third cylinder 26. The second bidirectional shaft reducer 21 is mounted on the upper surface of the extension frame 5. Motors are installed at the input ends of both the first bidirectional shaft reducer 11 and the second bidirectional shaft reducer 21. The motors drive the first bidirectional shaft reducer 11 and the second bidirectional shaft reducer 21 respectively, thereby rotating the first connecting rod 12 and the second connecting rod 22. The output shafts of the second bidirectional shaft reducer 21 face both sides and are respectively connected to the second connecting rod 22. The second connecting rod 22 is supported by bearing seats mounted on the upper surface of the extension frame 5. The outer end of the slide is equipped with a second gear 27. There are two slides 23, which are movably mounted on the upper surface of the crossbeam 3 via the first linear guide rail 28. The lower surface of the slide 23 meshes with the second gear 27 via the second rack 29. The outer ends of the slides 23 are connected to the translation crossbar 24. Several fourth guide frames 30 are arranged on the outer side of the translation crossbar 24 and in the vertical direction. A baffle 25 is movably arranged inside the fourth guide frame 30. The baffle 25 slides with the fourth guide frame 30 via the fifth linear guide rail 34 to ensure that the baffle 25 slides stably along the fourth guide frame 30. A third cylinder 26 is arranged on the outer side of the fourth guide frame 30. The piston rod of the third cylinder 26 faces upward and is connected to the top of the baffle 25.

[0030] Working method and operating principle: First, the motor and the second bidirectional shaft reducer 21 work together to drive the second connecting rod 22 to rotate. The second gear 27 engages with the second rack 29 on the lower surface of the slide bar, causing the slide table 23 to move towards the column 2. Then, the third cylinder 26 drives the baffle 25 to descend, and the piston rod of the first cylinder 9 retracts, thus extending the upper support plate 8 to receive the C-shaped steel. The interlocking C-shaped steel is moved horizontally to the upper support plate 8 by a transfer device (such as a forklift or roller conveyor belt) and limited by the baffle 25. The motor drives the first connecting rod 12 to rotate through the first bidirectional shaft reducer 11. The engagement of the first gear 18 and the first rack 19 drives the lifting column 13 and the lifting crossbar 14 to rise, thereby raising the lower support plate 15. At this time, the lower support plate 15 is retracted by the piston rod of the second cylinder 16 to be in an extended state and located below the upper support plate 8. Next, the piston rod of the first cylinder 9 pushes outward, causing the upper support plate 8 to retract. Then, blocked by the baffle 25, the first group of C-shaped steel falls onto the lower support plate 15. Subsequently, the upper support plate 8 extends again, moving the second group of interlocking C-shaped steel onto the upper support plate 8. The first bidirectional shaft reducer 11 drives the first connecting rod 12 to rotate, and through the cooperation of the first gear 18 and the first rack 19, the lifting upright 13 and the lifting crossbar 14 descend by the height of one C-shaped steel. The upper support plate 8 retracts, thus achieving the stacking of two groups of C-shaped steel. The above steps are repeated to complete the stacking of all C-shaped steel. After stacking is completed, the baffle 25 is lifted by the cooperation of the fourth cylinder, and the bottom of the stacked C-shaped steel is supported by the material transfer device, thus removing it from the stacking machine used for small bundles of C-shaped steel. This utility model has a reasonable structure. First, the retractable upper support plate 8 supports the C-shaped steel during feeding. Then, the liftable lower support plate 15 supports the C-shaped steel. The baffle 25, which moves with the slide table 23 and can be lifted, limits the C-shaped steel. When the upper support plate 8 is retracted, the C-shaped steel is limited by the baffle 25 and falls on the lower support plate 15, thus realizing the gradual stacking of C-shaped steel. This stacking method is more neat, efficient and safer than the manual method of hoisting equipment and manual alignment.
