Description

Technical Field

[0001] The invention relates to the technical field of metal packaging, and in particular to an automatic packaging device and method for steel coils with anti-rust paper. Background Art

[0002] As my country's steel output continues to increase, annual steel production ranks first in the world. The steel industry has become an important supporting force for my country's national economy. Stainless steel, as a corrosion-resistant product, has an increasing market demand, especially in the chemical, pharmaceutical and food packaging fields.

[0003] Stainless steel products are usually divided into two states: plates and coils. In order to improve the production efficiency of enterprises and save manufacturing costs, enterprises often reduce the production of plates and increase the output value of coils. With the increase in the proportion of steel coil products, the last process of the unit production line - tin-plated chrome-plated steel coil packaging has become more and more important. Since steel coils need to be stored and transported many times in production workshops and dispatching centers during the supply process, and tin-plated chrome-plated steel coils have very high requirements for appearance quality, without good outer packaging, the steel coils will rust and ultimately fail to meet customer satisfaction. Therefore, the study of tin-plated chrome-plated steel coil packaging plays a vital role in improving production efficiency and ensuring production quality.

[0004] At present, the domestic and foreign steel coil packaging methods can be divided into three categories: a) traditional manual packaging, in which the staff completes the anti-rust paper wrapping, folding and sealing processes in sequence; b) semi-automatic packaging device, in which the machine completes the anti-rust paper wrapping, and the folding and tape sealing are performed manually; c) fully automatic packaging device, using a winding machine to wrap the steel coil from the inner core to the outside to complete the packaging.

[0005] Among them, traditional manual packaging has the disadvantages of poor packaging effect, high labor intensity and low production efficiency. Especially with the increase of rolling speed and production output, traditional manual packaging cannot meet production needs. Semi-automatic packaging devices require special packaging equipment assistants to complete the packaging operation. Workers will come into contact with anti-rust paper during work, causing surface contamination of the anti-rust paper and resulting in surface quality defects of steel coils. The fully automatic wrapping packaging machine has requirements for packaging materials for steel coils, usually PE film, but PE film cannot replace anti-rust paper to ensure the surface quality of steel coil products, and a large amount of PE film is required for wrapping steel coils. Improper post-processing will cause pollution to the environment. Summary of the invention

[0043] The first step is that the anti-rust paper cutting device B processes the edge of the anti-rust paper b1;

[0044] Before starting to pack the steel coil f1, first process the edge of the packaging material anti-rust paper b1. Driven by the shearing roller b10 and the supporting roller b11, the edge of the anti-rust paper b1 is trimmed and cut into a trapezoidal shape to facilitate the later edge folding. The anti-rust paper guide b5 rotates under the action of the brake cylinder b7, and transmits the trimmed anti-rust paper to the anti-rust paper winding roller b6. The winding roller rotates by the winding motor b13 to rewind the trimmed anti-rust paper. When the rewound anti-rust paper is enough to pack the steel coil, the cutting machine b12 cuts the anti-rust paper horizontally, and the anti-rust paper guide b5 is driven by the gear b9 and rack b8 to restore the vertical state, completing the preliminary processing of the anti-rust paper.

[0045] In the second step, the steel coil lifting device F drives the steel coil f1 to move upward;

[0046] The steel coil f1 begins to rise under the action of the lifting hydraulic cylinder f4 and reaches a rotatable height. The steel coil support frame f2 is used to fix and support the steel coil f1 to prevent it from rolling during the rising process.

[0047] In the third step, the steel coil rotating device A starts to move linearly, moving the fan-shaped telescopic plate a7 to the steel coil core;

[0048] Among them, the brake motor a1 transmits power to the moving screw a12 through the screw coupling a9, and the moving screw a12 is provided with a screw nut a10, so that the nut seat a11 fixed on the screw nut a10 moves laterally, driving the rotating device forward; after the rotating device enters the steel coil core, it stops moving when the middle part of the fan-shaped telescopic plate a7 moves to the middle part of the steel coil f1. Under the action of the expansion and contraction hydraulic cylinder a3, the fan-shaped telescopic plate a7 is connected with the expansion and contraction hydraulic cylinder a3, so that the fan-shaped telescopic plate a7 is extended to press the steel coil f1.

[0049] In the fourth step, the rotating shaft a6 in the steel coil rotating device A starts to rotate, driving the steel coil to rotate along a fixed axis, and the anti-rust paper on the roll is wrapped on the surface of the steel coil. The steel coil side sealing device C presses down against the tail of the anti-rust paper to seal, completing the side sealing of the steel coil;

[0050] Among them, the steel coil side sealing device C starts to move vertically downward under the drive of the 8A chain and sprocket combination c9; the clamping claws in the horizontal tape machine c7 clamp the cut anti-rust paper and move downward together, the chain connects the vertical guide rail and the slider in the slider combination c2 through the L-shaped connecting plate c8, thereby driving the device to move downward, the edge of the horizontal tape machine c7 presses the head of the anti-rust paper against the side of the steel coil, pulls the tape apart through the internal gripper, the cutting knife cuts the tape, and the fan-shaped pressing plate seals the tape to the end of the anti-rust paper and fixes it to the steel coil under the action of the downward pressure cylinder c6, the horizontal tape machine c7 presses and seals again to complete the edge sealing work of the steel coil f1 and the anti-rust paper b1, the clamping claws relax, and the steel coil side sealing device C moves upward to complete the side covering work of the steel coil f1.

[0051] In the fifth step, after the edge of the anti-rust paper b1 is fixed, the anti-rust paper folding device D and the steel coil end surface sealing device E move downward, the nylon wheel d4 of the anti-rust paper folding device D is at the edge of the steel coil f1, and the anti-rust paper folding of the steel coil edge is completed by the self-rotation of the steel coil f1, and the tape machine e4 of the steel coil end surface sealing device E performs linear sealing on the end of the steel coil, and the steel coil end surface sealing work is completed by relying on the rotation of the steel coil.

[0052] The rust-proof paper folding device D and the steel coil end surface sealing device E are respectively driven by the 10A chain and sprocket combination d3 and the 12A chain and sprocket combination e3 to move downward and stop at the middle height of the steel coil. The rust-proof paper folding device D and the steel coil end surface sealing device E are respectively provided with nylon wheels d4 and adhesive tape machines e4 on both sides of the steel coil. The nylon wheel d4 is supported by the arch rod d2 and moves to the edge of the steel coil by the power provided by the guide cylinder d1. As the steel coil rotates, the rust-proof paper on the edge of the steel coil is folded; the adhesive tape machine is connected to the guide rod e2, and under the action of the guide rod cylinder e1, the folded rust-proof paper is sealed along a straight line, and the rust-proof paper sealing of the steel coil end surface is completed as the steel coil rotates.

[0053] Step 6. After the work is completed, the anti-rust paper folding device D and the steel coil end sealing device E are reset, the steel coil lifting device F is raised and the steel coil support frame is used to support the wrapped steel coil, the expansion and contraction hydraulic cylinder a3 is unloaded, the steel coil rotating device A is reset, and the steel coil lifting device F is reset to complete the anti-rust paper packaging of the steel coil.
