Description

Technical Field

[0001] This utility model relates to the field of packaging cutting technology, and in particular to a steel coil packaging material cutting machine. Background Technology

[0002] As a pillar industry of the national economy, the standardization of product forms and the improvement of logistics efficiency are core issues for the steel industry's development. Steel coils, as one of the main finished forms of steel, undergo multiple stages from production enterprises to end users, including warehousing, rail transport, and road transshipment. The reliability of packaging protection directly determines the final use value of the steel coils. Taking cold-rolled steel coils for automobiles as an example, their surface quality requirements are extremely high. If improper packaging leads to scratches and rust on the surface, even minor damage can cause the entire coil to be downgraded, resulting in significant losses. Therefore, steel coil packaging materials must possess composite functions of physical protection, rust prevention, moisture protection, and labeling. The dimensional accuracy of these materials is a key prerequisite for ensuring protective effects. The width of the rust-proof paper needs to be greater than the actual width of the steel coil by a certain margin to ensure complete edge coverage. If the cut is too narrow, the exposed parts are prone to rust; if it is too wide, it will result in material waste and increased packaging costs. As the steel industry moves towards a high-quality development stage, the application of new packaging materials is becoming increasingly widespread, placing higher demands on cutting methods.

[0003] Hot-rolled steel coils are heavy, and the width and length of the accompanying rust-proof paper are correspondingly large. When cutting manually, multiple people are needed to complete the unwinding, marking, and cutting operations. Due to the thickness of the material, the cutting edge is prone to deviation during the cutting process, resulting in large dimensional errors and low processing efficiency, making it difficult to meet the production capacity requirements of the steel rolling workshop. Automated technology can achieve precise cutting of packaging materials, effectively solving the drawbacks of manual operation. It has become a key piece of equipment for improving packaging efficiency, ensuring packaging quality, and reducing costs, playing an important role in steel production and related logistics. However, during the unwinding process, the coil lacks a stable limiting device. As unwinding progresses, the coil is prone to gradually deviating from the preset path due to uneven weight and installation gaps, causing deviations in the material position of subsequent processes, which in turn affects the dimensional accuracy of the final product. Utility Model Content

[0039] Working principle: After the roll material 204 is placed on the support frame 201, the roll material 204 is initially fixed by sliding the limiting sleeves 205 on both sides, which can quickly and roughly position the roll material 204 and prevent it from shaking significantly in subsequent operations. Then, the motor 3 2092 drives the rotation of the bevel gear 1 2093. The rotation of the bevel gear 1 2093 drives the rotation of the meshing bevel gear 2 2094, which in turn drives the rotation of the threaded rod 2095, thereby causing the support plate 206 to start moving upward. The limiting guard plate 207 completes the contact with the installation roller 203. Then, the motor 2 2081 drives the support plate 206 to move upward. The rotation of the precision gear 2082 drives the toothed strip 2083 to move in opposite directions, completing the opposite movement of the limiting guard plate 207. This achieves clamping and limiting of the roll material 204 of different specifications, preventing the roll material 204 from gradually shifting when the motor 202 drives the mounting roller 203 to rotate. This ensures that the roll material 204 always maintains the correct position during the unwinding process, ensuring that subsequent cutting can be carried out based on precise material feeding. This improves the overall processing accuracy, avoids material waste caused by the offset of the roll material 204, reduces defective products caused by positional deviation, and improves the stability and efficiency of production.

[0040] According to different cutting requirements, the adjustment plate 301 is pushed to the appropriate cutting position. Then, the U-shaped buckle 3071 engages with the corresponding positioning hole 3072 to fix the position of the adjustment plate 301. This can quickly and firmly lock the cutting position, providing a stable foundation for subsequent cutting, adapting to diverse cutting requirements, eliminating the need for complicated adjustment processes, and improving operational efficiency. Then, the servo motor 303 drives the rotation of the fine gear 304. The rotation of the fine gear 304 causes the meshing toothed strip 305 to move up and down, and the cutting blade 306 moves up and down, thereby achieving the cutting effect on the roll material 204. This ensures the accuracy of the cutting dimensions, reduces cutting errors, reduces material waste and rework caused by non-compliance with cutting requirements, and further improves production efficiency and product qualification rate.
