Description

Technical Field

[0001] The present invention relates to the technical field of sheet conveying, and specifically relates to a sheet dropping and conveying device. Background Art

[0002] A sheet dropping and conveying device is a mechanical device used to stably and efficiently convey sheets from a high place to a low place, and is widely used in industries such as construction, furniture manufacturing, and logistics warehousing. When stacking sheets, although a forklift is a commonly used tool for removing sheets, in certain specific situations, other sheet conveying devices may be selected to remove sheets.

[0003] When a forklift cannot enter the area where the sheets are stacked, such as a narrow space, a narrow passage, or the presence of obstacles, the forklift may be unable to operate or turn. Therefore, a more flexible and smaller sheet conveying device is needed. Summary of the Invention

The several plates 3 are linearly arranged from top to bottom in sequence. The size of the plates 3 and the through openings are mutually matching. On the right side of the placement frame 1, there is a contraction plate 2 fixedly connected. The contraction plate 2 is inclined. Inside the contraction plate 2 near the right side, there is a buffer plate 27. On the right side of the buffer plate 27, there are two round rods 29 fixedly connected. The right ends of the two round rods 29 pass through the inner side wall of the contraction plate 2 and are fixedly connected with round plates 30.

[0031] Both the front and back sides of the placement frame 1 are fixedly connected with connecting plates 7 near the left side. The tops of the two connecting plates 7 are fixedly connected with guide plates 6. Guide openings are formed in the guide plates 6. A fixed frame 8 is fixedly connected to the right side of the guide plate 6 at the rear. A first motor 9 is installed at the rear of the fixed frame 8. There is a first winding wheel in the inner cavity of the fixed frame 8. The power output shaft of the first motor 9 penetrates the inner cavity of the fixed frame 8 and extends into the inner cavity of the fixed frame 8. The power output shaft of the first motor 9 penetrates the inner cavity of the first winding wheel and is fixedly connected thereto. A first pulling rope is wound around the outside of the first winding wheel. The first pulling rope penetrates the guide plate 6 at the rear and extends into the inner cavity of the guide opening. Both sides of the two guide openings near the bottom are in contact with sliders 25. Hinged to the corresponding sides of the two sliders 25 are placement plates 10. The other end of the first pulling rope is fixedly connected to the adjacent slider 25. The tops of the two sliders 25 are fixedly connected with welding plates 26. An air cylinder 24 is installed in the inner cavity of the welding plate 26. The air cylinder 24 is inclined. The power output shaft of the air cylinder 24 is fixedly connected to the placement plate 10. A fixed plate 11 is fixedly connected between the two welding plates 26. There is a second motor 14 near the bottom at the rear of the guide plate 6 at the rear. An L-shaped sleeve plate 31 is fixedly connected to the rear of the guide plate 6 at the rear near the bottom. The power output shaft of the second motor 14 penetrates the L-shaped sleeve plate 31 and is fixedly connected with a second winding wheel. A second pulling rope is wound around the outside of the second winding wheel.

The other end of the second pulling rope is fixedly connected to the slider 25. A trigger is installed on the inner side wall of the guide opening at the front near the shrinkage plate 2.

[0032] Working principle: First, the staff places the plate 3 on the top of the placement plate 10 and starts the first motor 9. When the first motor 9 is started, the first winding wheel can be driven to rotate through the power output shaft of the first motor 9. When the first winding wheel rotates, the adjacent slider 25 can be driven to slide along the inner wall of the guiding port through the first pulling rope. When the rear slider 25 moves, the rear slider 25 can drive the front slider 25 to move synchronously through the fixing plate 11. When the front slider 25 moves, the trigger can be started. When the trigger is started, two cylinders 24 can be triggered. When the two cylinders 24 are started, they can push the two placement plates 10 to flip towards each other, so that the plate 3 falls downward into the inner cavity of the placement frame 1, completing the feeding work of the plate 3. When the main motor 15 is started, the main driving sheave 21 can be driven to rotate through the power output shaft. When the main driving sheave 21 rotates, the driven sheave 22 can be driven to rotate through the belt 20. The rotation of the driven sheave 22 can drive the adjacent transmission rod 23 to rotate. When the transmission rod 23 rotates, the sprocket 19 can be driven to rotate. When the sprocket 19 rotates, the chain 13 can be driven to rotate. When the chain 13 rotates, the push plate 16 can be driven to move in a circular motion. When the push plate 16 rotates one week and enters the inner cavity of the rectangular port, it can drive the plate 3 located below to move to the right. When the plate 3 moves to the right, it can pass through the through port and slide onto the surface of the retractable plate 2. When the plate 3 is in contact with the surface of the retractable plate 2, it can slide onto the surface of the buffer plate 27 to complete buffering.
