Cleaning device for melt-blowing mold head and cleaning method of cleaning device

Abstract

The invention discloses a cleaning device for a melt-blowing mold head and a cleaning method of the cleaning device. The cleaning device comprises a machine box; a sealing door is arranged on the side face of the machine box; a mounting groove is formed in the bottom of the machine box; a plurality of heating pipes and ultrasonic transducers are arranged in the mounting groove; a material trolley is arranged in the machine box; a trolley body of the material trolley is of a grating structure; the area of the mounting groove is smaller than that of the material trolley; the outer portion of the machine box is connected with a batching mechanism and a recycling mechanism; and cleaning liquid is arranged in the batching mechanism. The cleaning device is reasonable in structure and convenient to use; and the cleaning liquid in the machine box can quickly dissolve organic matter blocked in micropores of the mold head of a mold under the assistance of heating and ultrasonic waves, the cleaning efficiency is high, smooth cleaning of the interiors of the micropores of the mold head of the melt-blowing mold can be ensured, the interiors of the micropores are not damaged, the cleaning time is short, the service life of the mold is remarkably prolonged, the condition that the micropores are blocked in processing is improved, and the overall production efficiency of melt-blown cloth is improved.

Description

technical field [0001] The invention relates to the technical field of melt-blown cloth, in particular to a cleaning device for a melt-blown die head and a cleaning method thereof. Background technique [0002] The melt blown mold is the core component of the production of melt blown cloth, and the core part of the melt blown mold is the die head. At present, the hole diameter of the melt blown die head generally ranges from 0.15 to 0.4 μm, the hole depth is 10 to 20 mm, and the hole interval is 0.6 ~2mm. Due to the small pore size and the melt blown raw material is polypropylene, which is melted at a high temperature above 300°C and then sprayed out through the die head, if the process is improperly used or shut down during the processing, after the processing of the interrupted polypropylene cools down, it is easy to melt The micropores of the die head and the grooves on the die head are all blocked, which directly affects the quality and output of the melt blown cloth pr...

Problems solved by technology

Due to the small pore size and the melt blown raw material is polypropylene, which is melted at a high temperature above 300°C and then sprayed out through the die head, if the process is improperly used or shut down during the processing, after the processing of the interrupted polypropylene cools down, it is easy to melt The micropores of the die head and the grooves on the die head are all blocked, which directly affects the quality and output of the melt blown cloth production

[0003] At present, most manufacturers use an oven above 400°C to bake the melt-blown mold to carbonize the organic matter in the holes of the melt-blown die, and then use tools to clean the micropores one by one. The whole process takes at least 4 to 5 hours and takes a long time. , labor-intensive

However, after manual cleaning, since the interior is difficult to clean during the process of using tools to dredge the small holes, ultrasonic equipment will be added for professional cleaning in the later stage, which increases the cost and man-hours

In addition, in the process of cleaning the small hole, the cleaning tool will inevitably rub against the inner wall of the small hole, and the roughness of the inner wall of the small hole will inevitably increase, which will significantly reduce the service life of the mold and increase the possibility of the mold being blocked during the production process. sex
