Description

Technical Field

[0001] The utility model relates to a cushioning air bag for paper pulp transportation. Background Art

[0002] When pulp is transported by a pulp transport ship, there are gaps between the pulp bales in the cargo hold. If there are no buffers or fillers between the gaps, the hull will sway violently when the ship is at sea or encounters severe sea conditions. The gaps between the pulp bales will cause collisions and friction between the pulp bales, which will damage the outer packaging of the pulp bales over time, causing the pulp to rupture and break, and the cargo to be destroyed. Summary of the invention

[0003] In order to solve the above technical deficiencies, the utility model provides a cushioning airbag for pulp transportation, which has low use cost and reduces cargo transportation loss.

[0004] The utility model is achieved through the following measures:

[0005] A cushioning airbag for pulp transportation comprises a flat bladder body which can be inflated with gas, an inflation and deflation nozzle is embedded in the edge of the bladder body, a threaded pressing sheet which is threadedly connected to the inflation and deflation nozzle and is close to the bladder body, and a side wall of the bladder body comprises an inner airtight layer, a skeleton layer and an anti-wear layer which are compositely stacked in sequence from the inside to the outside, and the outer surface of the anti-wear layer is provided with a concave and convex wear-resistant pattern.

[0006] The bladder body is composed of two rectangular composite substrates stacked up and down and sealed together at the edges. Each composite substrate includes an inner airtight layer, a skeleton layer and an anti-wear layer stacked in sequence from the inside to the outside, and a reinforcing ring belt is bonded together at the edges of the two composite substrates.

[0007] A plurality of hand straps are integrally connected outwardly to the edge of the bag body.

[0008] The inner airtight layer and the anti-wear layer are both rubber layers, and the skeleton layer is a warp and weft mesh cloth woven from fiber filaments.

[0009] The reinforcing ring belt is made of rubber, and the cross section of the reinforcing ring belt is a C-shape opening toward the inside of the bladder body, and the two opened side walls of the reinforcing ring belt are respectively bonded to the two composite substrates.

[0010] The beneficial effects of the utility model are: the bladder is thin and light, easy to move and fix, can meet the filling and buffering needs of various gaps, has low use costs, and reduces cargo transportation losses; the inflation and deflation nozzles have universal interfaces, which facilitate valve connection and inflation and deflation; the external wear-resistant patterns strengthen the buffering limit of the cargo and improve the buffering effect.

[0016] The utility model is further described in detail below in conjunction with the accompanying drawings:

[0017] like Figure 1-4 As shown, the utility model discloses a cushioning airbag for pulp transportation, in which a rubber airbag is inserted between the gaps. After being inflated, the airbag expands and fills the gaps. At the same time, the high pressure in the airbag ensures that the pulp bags on both sides of the airbag are limited when the hull sways and cannot move, thereby protecting the integrity of the pulp bags.

[0018] Specifically, it includes a flat bladder 1 that can be filled with gas, which can be rectangular, but is not limited to this shape, and the length and width are determined according to actual needs. The edge of the bladder 1 is embedded with a gas filling and discharging nozzle 2, and a threaded pressing sheet 3 that is close to the bladder 1 is threadedly connected to the gas filling and discharging nozzle 2. The threaded pressing sheet 3 can protect the joint between the bladder 1 and the gas filling and discharging nozzle 2 to prevent accidental expansion and wear, and can also achieve airtight compaction to reduce the risk of gas leakage. The side wall of the bladder 1 includes an inner airtight layer 8, a skeleton layer 7 and an anti-wear layer 6 that are compositely superimposed from the inside to the outside, and the outer surface of the anti-wear layer 6 is provided with a concave and convex wear-resistant pattern 5. The bladder 1 can be composed of two rectangular composite substrates that are superimposed on each other and sealed and bonded together at the edges. Each composite substrate includes an inner airtight layer 8, a skeleton layer 7 and an anti-wear layer 6 that are compositely superimposed from the inside to the outside, and a reinforcing ring belt 9 is bonded to the edge bonding of the two composite substrates. The edge of the bladder body 1 is integrally connected to a plurality of hand straps 4, which facilitates carrying the pulp airbag. At the same time, ropes can be connected to fix and tighten the position of the pulp airbag. The inner airtight layer 8 and the anti-wear layer 6 are both rubber layers, and are not limited to rubber materials. The inner airtight layer implemented to ensure the overall airtightness of the bladder body 1 is generally a rubber with particularly good airtightness to achieve no air leakage.

[0019] The outer surface of the anti-wear layer 6 is provided with a concave-convex wear-resistant pattern 5. The friction coefficient is increased by the concave-convex wear-resistant pattern 5, and the overall anti-wear characteristics are improved by improving the hardness and wear resistance of the material itself, so as to meet the extrusion and friction conditions under high pressure for a long time. The skeleton layer 7 is a warp and weft grid cloth woven from fiber filaments, and the uniformity of its warp and weft strength is not limited. The reinforcing ring belt 9 is made of rubber material, and the cross-section of the reinforcing ring belt 9 is a C-shape opening to the inside of the bladder 1, and the two open side walls of the reinforcing ring belt 9 are respectively bonded to two pieces of composite substrates. The reinforcing ring belt 9 is bonded between the two combined layers, which serves to tighten the upper and lower layers internally during inflation to meet the strength requirements and achieve working air pressure safety. The structure of the reinforcing ring belt 9 is a rubber layer of a composite material, which has a certain tensile strength and can also meet the airtightness performance.

[0020] The above is only a preferred implementation of this patent. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of this patent. These improvements and substitutions should also be regarded as the scope of protection of this patent.
