Maintenance system and maintenance method for spinning nozzle of melt-blowing machine for manufacturing melt-blown cloth

Abstract

The invention discloses a maintenance system and maintenance method for a spinning nozzle of a melt-blowing machine for manufacturing melt-blown cloth. The maintenance system comprises a working box; a water storage cavity with an upward opening is formed in the working box; a spray spinning nozzle blockage cleaning mechanism is arranged on the water storage cavity; an abrasive impurity separation mechanism is arranged on the lower side end face of the working box; and an abrasive mixing pressurization mechanism is arranged on the abrasive impurity separation mechanism. According to the invention, high-pressure water flow is mixed with low-hardness abrasive to dredge and clean spraying holes of the spinning nozzle of the melt-blown cloth, the capacity of cleaning and removing condensate in the spraying holes through the water flow mixed with the low-hardness abrasive is greatly improved, and therefore the requirement for water pressure can be greatly lowered; ultrahigh-pressure water flow equipment does not need to be adopted, so that the equipment cost is reduced; meanwhile, the low-hardness abrasive can avoid damaging the spinning nozzle of the melt-blown cloth; and the abrasive feeding amount can be automatically adjusted, so that the mixing proportion of the abrasive and water is guaranteed, and the dredging and cleaning effect is guaranteed.

Description

technical field [0001] The invention relates to the technical field of melt-blown machines, in particular to a maintenance system and method for a spinneret of a melt-blown machine used for manufacturing melt-blown cloth. Background technique [0002] The melt blown machine is a device for manufacturing mask filter melt blown cloth. After working for a period of time, the melt blown cloth spinneret on the melt blown machine will form condensation in the nozzle and gradually block the nozzle hole, making the nozzle lose its working efficiency. , it is necessary to regularly clean the blocked nozzle holes on the nozzle body. At present, the cleaning and dredging methods mainly include manual cleaning, high temperature melting method, dry ice cleaning method, ultrasonic cleaning method and ultra-high pressure water jet cleaning method, of which manual cleaning and dry ice cleaning method , The cleaning efficiency of ultrasonic cleaning method is low and the effect is not ideal....

[0002] The melt blown machine is a device for manufacturing mask filter melt blown cloth. After working for a period of time, the melt blown cloth spinneret on the melt blown machine will form condensation in the nozzle and gradually block the nozzle hole, making the nozzle lose its working efficiency. , it is necessary to regularly clean the blocked nozzle holes on the nozzle body. At present, the cleaning and dredging methods mainly include manual cleaning, high temperature melting method, dry ice cleaning method, ultrasonic cleaning method and ultra-high pressure water jet cleaning method, of which manual cleaning and dry ice cleaning method , The cleaning efficiency of ultrasonic cleaning method is low and the effect is not ideal. The water pressure is higher, so that the cost of maintaining the equipment is higher, and a kind of equipment that can solve the above problems explained by the present invention
