Description

Technical Field

[0001] The invention relates to the field of steel coil packaging, and more specifically, to a supporting auxiliary lining for steel coil packaging. Background Art

[0002] During the packaging process of steel coils, the core of the steel coil needs to be lined with anti-rust. In the original packaging process and process of steel coils, the core lining was first packaged with lining paper. Because the lining paper is thicker and has a certain support rigidity, it can fit on the inner wall of the core after being inserted into the core. The operator can complete the packaging operation alone, but the price of lining paper is relatively expensive, about 8,000 yuan per ton, and the weight per square meter is nearly 500 grams. With the increase in the number of steel rings, the cost of using lining paper to complete the packaging is also a considerable expense. After a year of statistics, the cost is even more considerable, which is not in line with the spirit of cost reduction and efficiency improvement. In order to complete the process of packaging steel coils and reduce costs, under the premise of meeting the anti-rust performance, we have found a kind of anti-rust paper to replace the lining paper after many experiments and comparisons. Compared with the lining paper, this anti-rust paper is slightly more expensive, but the material of the anti-rust paper is thin, and the weight per square meter is only 180 grams, which is 2.5 times the weight difference between the two. If anti-rust paper is used, it will definitely reduce the cost of the packaging process. However, the anti-rust paper is relatively lacking in supporting rigidity. After being inserted into the steel coil core, it will naturally sag and collapse. Operators usually need to hold it up by hand during the packaging process. Especially when the width of the steel coil exceeds 1600mm, even if both ends of the anti-rust paper need to be manually supported by hand, two people are required to work together to support the anti-rust paper before packaging. Even so, the middle part will still sag and the core anti-rust paper needs to be supported multiple times, which creates new problems in the packaging process, that is, affecting production efficiency. How to reduce costs without affecting production efficiency is a problem that must be solved on site during the current packaging process. Summary of the invention

[0003] The purpose of the present invention is to provide a support auxiliary lining for steel coil packaging, which can reduce costs and improve the production efficiency of steel coil packaging, in order to solve the problem that the above-mentioned packaging process has high costs and needs to reduce costs and increase efficiency without affecting production efficiency.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] The present invention provides a supporting auxiliary lining for steel coil packaging, comprising anti-rust paper and a flexible plate, the anti-rust paper being unfolded into a closed loop in a steel coil core, a flexible plate, hoops arranged at both ends of the flexible plate and an adsorption mechanism arranged on the side of the hoops, the hoops being fixed to both sides of the flexible plate by a connecting mechanism, and the flexible plate being made of PE plastic. As one aspect of a supporting auxiliary lining for steel coil packaging, the hoops include a first hoops arranged on the left side of the flexible plate and a second hoops arranged on the right side of the flexible plate, and the first hoops and the second hoops are both made of steel.

[0006] As one aspect of a supporting auxiliary lining for steel coil packaging, the connecting mechanism includes a plurality of threaded holes respectively arranged on the first hoop head and the second hoop head and bolts inserted into the threaded holes.

[0007] As one aspect of a supporting auxiliary lining for steel coil packaging, the connecting mechanism also includes a plurality of mortise holes arranged on the first hoop head and the second hoop head, and rivets connected to the mortise holes in cooperation with the mortise holes.

[0017] The technical solution of the present invention is specifically described below in conjunction with the drawings in the specification. The detailed features and advantages of the present invention are described in detail in the specific implementation mode. The content is sufficient to enable any technical personnel in the field to understand the technical content of the present invention and implement it accordingly. According to the description, claims and drawings disclosed in this specification, the technical personnel in the field can easily understand the relevant purposes and advantages of the present invention.

[0018] Figure 1 The structure diagram of the supporting auxiliary lining for steel coil packaging of the present invention is shown; Figure 1 As shown, it includes anti-rust paper 2 and a flexible board 1, hoops arranged at both ends of part 11 of the flexible board and an adsorption mechanism arranged on the side of the hoop, and the hoop is fixed on both sides of the flexible board 1 (excluding the two side ends) through a connecting mechanism.

[0019] According to the actual situation of steel coil packaging, the supporting auxiliary lining for steel coil packaging needs to be light and soft, and can be rolled up with the anti-rust paper 2 and fed into the roll core. After unfolding to form a closed loop, it has a certain rigidity to support. Therefore, materials with too much rigidity cannot be used. The yield strength of ordinary steel is about 200Mpa, and it is difficult to recover after bending. The bending strength of PVC board is about 70-80Mpa, the bending strength is high, and it is easy to break after bending. PE plastic material can be bent at will and has a certain supporting toughness after unfolding. Therefore, PE plastic is selected as the material of flexible board 1.

[0020] Figure 2 It shows a schematic diagram of the structure in which the supporting auxiliary lining for steel coil packaging is laid flat on the anti-rust paper; Figure 3 It shows the front view of the steel coil packing supporting auxiliary lining after the anti-rust paper is inserted into the steel coil core; Figure 2 As shown, before adding the anti-rust paper 2 to the steel coil core, the operator usually lays the supporting auxiliary lining 1 for steel coil packaging flat on the anti-rust paper 2, rolls the supporting auxiliary lining 1 for steel coil packaging and the anti-rust paper 2 into a barrel shape, which is located inside the outer ring 4 of the steel coil, and then inserts it into the steel coil core 3 together with the anti-rust paper 2, and then unfolds the supporting auxiliary lining for steel coil packaging into a closed loop in the steel coil core 3. Figure 3 shown.

[0021] At present, the mainstream inner diameters of steel coil cores are φ508mm and φ610mm. According to the conversion (C=πd), the circumferences of the above two diameters are 1595mm and 1916mm respectively. Therefore, the total length of the supporting auxiliary lining for steel coil packaging should refer to these two sizes to meet the needs of adapting the two inner diameters of the steel coil core.

[0022] The width of the supporting auxiliary lining 1 for steel coil packaging is determined according to the actual width of the finished coil to be packaged. In actual operation, the width of the supporting auxiliary lining 1 for steel coil packaging must be smaller than the width of the packaged coil. Generally, it is ensured to be within one-third of the coil width to ensure that the anti-rust paper 2 is propped up. At present, the mainstream steel coil width is 350mm-1800mm, so the width of the supporting auxiliary lining 1 for steel coil packaging is between 100-600mm, and multiple common sizes can be produced to cover all finished products.

[0023] The hoop head includes a first hoop head 12 arranged on the left side of the flexible plate and a second hoop head 13 arranged on the right side of the flexible plate. The first hoop head 12 and the second hoop head 13 are both made of steel. The first hoop head 12 and the second hoop head 13 are fixed to both sides of the flexible plate by a connecting mechanism. The connecting mechanism can be a screw hole connecting mechanism or a riveting connecting mechanism. Figure 1 As shown, the screw hole connection includes threaded holes respectively arranged on the first hoop head 12 and the second hoop head 13 and bolts 14 inserted in the threaded holes. The bolts 14 are M6 bolts, and the number of threaded holes 15 is 6-8; the riveted connection mechanism includes mortise holes arranged on the first hoop head 12 and the second hoop head 13 and rivets connected with the mortise holes.

[0024] Figure 4 The structure cross-sectional diagram of the adsorption mechanism of the present invention is shown. The adsorption mechanism includes a first magnet 16 embedded in the front section of the side of the first hoop head 12 and a second magnet 17 embedded in the front section of the side of the second hoop head 13. The first magnet 16 and the second magnet 17 are mutually adsorbed and connected. Figure 4 and Figure 1 As shown, magnets are embedded in the first hoop head 12 and the second hoop head 13 at both ends of the flexible plate 11. After being propped up in the steel coil core, they can be adsorbed to each other and can also be adsorbed on the steel coil, which is more convenient and firm. The supporting auxiliary lining 1 for steel coil packaging is adsorbed to each other by the first magnet 16 and the second magnet 17 to form a closed loop. At this time, the supporting auxiliary lining for steel coil packaging is affected by the toughness of the coil core and its own material, and can be formed into a circular ring without collapsing. The anti-rust paper 2 is propped up in the steel coil core under the action of the supporting auxiliary lining for steel coil packaging. At this time, the operator can perform normal packaging alone. By introducing the supporting auxiliary lining for steel coil packaging, the cost of the flexible plate is also very low, and it can be used repeatedly, which can reduce costs and improve production efficiency. It is currently widely promoted and applied in production sites.

[0025] Finally, it should be pointed out that although the present invention has been described with reference to the current specific embodiments, ordinary technicians in this technical field should realize that the above embodiments are only used to illustrate the present invention and are not used as a limitation of the present invention. Various equivalent changes or substitutions can be made without departing from the concept of the present invention. Therefore, as long as the changes and modifications to the above embodiments are within the essential spirit of the present invention, they will fall within the scope of the claims of the present invention.
