It is usually seen that the flat-headed aluminum packaging hose is filled with adhesive. As the structure of the existing aluminum packaging hose is flat-headed, once the user opens it, the residual glue is easy to solidify due to the large opening, which brings great inconvenience to consumers for the next use and even affects their continued use.
Characteristics and uses of rubber hose
Adhesive packaging hose is one of the necessary packages for holding paste or sticky adhesive products. Common packaging hoses in the market, such as silicone sealants packaging hose, polyurethane sealant packaging hose, ms glue packaging hose, etc. The curing principle of silicone sealants, polyurethane sealant and ms glue is that they contact water molecules in the air.
It is gradually solidified from the surface to the inside, and it is not suitable for contact with air before construction. If you meet water molecules in the air, they will solidify quickly, leading to the failure of the product before construction. In order to prevent the colloid from curing before construction, the container must be completely sealed, and air is not allowed to enter the pipeline.
There are some defects in the existing rubber packaging hose and nozzle sealing device: in order to ensure the product quality, the products on the market directly use the nozzle of the dense nozzle to achieve the sealing effect, but in the construction, the sealing nozzle needs to be drilled with a sharp cone tool to squeeze out the rubber in the hose, but the drilled nozzle forms a certain resistance to the rubber extrusion.
Especially, it has caused some difficulties in the construction of paste adhesive. There are also open hoses similar to those described in this patent in the market, but the sealing oil is usually injected into the nozzle manually, so the production efficiency is high. The upward protruding part of the tube core reduces the residual air in the tube, and sealing oil is filled in the threaded engagement space between the tube body and the tube cover.
Effectively prevent air from entering the pipeline, prolong the shelf life of products, improve the production and filling efficiency, reduce labor costs and improve construction efficiency; Therefore, it is necessary to develop an adhesive packaging hose and nozzle sealing device to improve product quality and realize automatic production in adhesive industry.
