Force dispersion type cold-rolled shipment interlayer padding

Abstract

The invention discloses a force dispersion type cold-rolled shipment interlayer padding. A three-layer fiberboard can be used as a core material, two sides of the core material are wrapped with high-density sponges, a composite force dispersion layer is inlaid in the high-density sponge, a force transmission structure arranged on the surface of the sponge is used for pre-dispersing the received force and then transmitting the pre-dispersed force to the composite force dispersion layer, the force is dispersed layer by layer and partially counteracted by utilizing the elasticity of the force dispersion layer itself and the distribution characteristics of a spherical structure, a good cushion protection effect can be achieved on the product, meanwhile, internal optimization is carried out ona single force dispersion layer, a special-shaped net is used for enhancing the integrality of the force dispersion layer, and a special force buffering layer is arranged among force dispersing ballsforming the force dispersion layer. According to the invention, a good elastic buffering effect is kept while the requirements for bundling, winding, cushioning and protection are met, the effect of coping with instantaneous impact hardening protection is also achieved, the force dispersion strength of the force dispersion layers is improved, the reliability of product cushioning and protection isextremely high, and the interlayer padding can be recycled, and the cushioning and protection cost of exported products can be greatly reduced in the long term.

Description

technical field [0001] The invention relates to the field of marine hoisting equipment, and more specifically, relates to a loose-force type cold roll shipping interlayer cushioning material. Background technique [0002] At present, the method of straw mat (bundle) is used for the protection of the cold roll room for automobile panels and electrical coils. Due to the method of using straw mat (bundle) as a lining, there are the following problems: 1. The weight of the briquette straw mat is heavy 1. The padding is more difficult during the operation, and it is easy to be unbalanced; 2. The straw in the straw pad is easy to fall off, which is easy to cause the straw to block the drain in the cabin, which brings hidden dangers to navigation safety; 3. Use straw pads (bundled ), cannot be recycled and reused, resulting in an inability to reduce the cost. 4. Grass pads (bundles) cannot be used in the shipment of export products, resulting in a gap in the professional field of ...

[0002] At present, the method of straw mat (bundle) is used for the protection of the cold roll room for automobile sheets and electrical coils. Due to the method of using straw mat (bundle) as a lining, there are the following problems: 1. The weight of the briquette straw mat is heavy 1. The padding is more difficult during the operation, and it is easy to be unbalanced; 2. The straw in the straw pad is easy to fall off, which is easy to cause the straw to block the drain in the cabin, which brings hidden dangers to navigation safety; 3. Use straw pads (bundled ), cannot be recycled and reused, resulting in an inability to reduce the cost

4. Grass pads (bundles) cannot be used in the shipment of export products, resulting in a gap in the professional field of cold roll interlayer protection in current export products

[0003] Although there are some simple temporary protections at present, such as using rubber strips, high-density sponges, etc. for pad protection, although they have certain advantages compared to straw pads (bundles), on the one hand, the protection effect is not satisfactory. The force cannot be effectively dispersed during vibration or impact, and it is still easy to cause damage to the product. On the other hand, under the protection of high-strength pads, ordinary rubber strips and other pads generally have a long service life, and mechanical fatigue damage of materials is prone to occur. The protective effect gradually deteriorates to the point that it cannot be used anymore, and the material cost is huge. Therefore, a new pad is urgently needed to solve this problem
