Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in figures 1-5, according to the size of the material roll, the core rod is adjusted to the most central position of the inner ring of the material roll, the nozzle thread connecting hole arranged on the core rod is sunk into the core rod body in proportion, the thread depth is adjusted as far as possible under the condition that the inner bore diameter of the core rod is not changed, and the nozzle is ensured not to fall off under the condition that the existing pressure (8 kilograms) can be borne.

Furthermore, the threaded connection mode of the core rod and the nozzle not only needs to meet the requirement that the fastened nozzle head cannot be higher than the surface of the core rod by 1cm, but also needs to meet the requirement that the nozzle head can be fastened on the core rod under the pressure of 8 kilograms without washing and dropping, and meanwhile, the diameter of an inner hole of the core rod cannot be changed, and the washing flow rate cannot be changed.

The structure of the nozzle is changed from original 60-degree spraying direction to 45-degree spraying direction, meanwhile, the diameter of the nozzle opening is reduced by half, pressure is guaranteed, and the material is changed into 316L stainless steel.

The principle of the nozzle and the core rod is that when a material roll enters a high-pressure water tank and reaches a set height position, the material roll starts to move forwards and backwards in parallel, an outer ring is washed by an annular spraying ring during advancing and retreating, an inner ring is washed by a core rod nozzle, a counter-sunk nozzle is arranged on the modified core rod, the angle of the nozzle is reduced, and the pressure is increased. When material is rolled up the translation and is passed through the nozzle, expose the core rod surface because of the nozzle and reduce, the inner circle messy silk will not scrape again and bump the nozzle, and the area is sprayed in the reduction of nozzle angle simultaneously, makes the pressure increase of washing, and the inner circle material will wash more totally with material crack department.

The nozzle of the original core rod and nozzle is made of 304 stainless steel, and the nozzle is easy to corrode when the wire coil is washed and is easy to drop after being corroded to cause insufficient pressure. The end of the core rod is connected with the nozzle without counter bores, the nozzle completely protrudes out of the core rod, and the inner ring of the coil easily pulls the nozzle to cause the core rod to be pulled askew.

The end part of the core rod is made of PPH material and is in threaded connection with the tail core rod, and meanwhile, the screw hole of the nozzle installed at the end part of the core rod sinks.

The core rod and the nozzle are combined and modified according to the fact that the corrosivity of the nozzle drops and the inner ring of the material roll drops, the dropping of the nozzle and the damage of the core rod are reduced through the change of the material of the nozzle, the end portion of the core rod is changed into the PPH material, the screw hole installed with the nozzle sinks to prevent the pulling and the like, and the flushing pressure is guaranteed.

In addition to the above embodiments, the present invention also includes other embodiments, and all technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
