Surface Smoothing Technology of Ring Wool Blanket

Abstract

The invention provides an annular woolen blanket surface flattening process. A conventional grinding process used for annular woolen blanket surface sorting in the prior art has the defects that the peak and trough problems due to too deep prickling marks on the surface of the woolen blanket cannot be eliminated, so that the surface flattening requirements cannot be achieved. In order to overcome the defects, the invention provides the annular woolen blanket surface flattening process, which comprises surface glue spraying, heating, grinding, cleaning and sorting, inspection and warehouse entering. According to the process, through glue spraying and heating treatment on the surface of the annular woolen blanket to be processed, the surface fiber is semi-solidified, has certain elasticity at the same time, and cannot be easily pulled out, a hair falling phenomenon does not occur, the surface is flat through the grinding work procedure, then, through cleaning, water-soluble glue is cleaned away, and high-temperature shaping and edge cutting are carried out, so that finished products meet the requirements of surface flatness, thickness uniformity and internal structure stability. The annular woolen blanket surface flattening process has the advantages that the process is simple, the cost is low, and particularly, the flattening effect on the surface of the annular woolen blanket is good.

Description

[0001] Technical field [0002] The invention relates to the technical field of industrial woolen blanket production technology, in particular to a process for leveling the surface of an annular woolen blanket. Background technique [0003] The surface smoothness of the circular woolen blanket produced by acupuncture is the main technical index of the product, and it is also one of the key technologies for the production of the circular woolen blanket. Due to the existence of the circular woolen blanket in the acupuncture process, the amount of hair on each needle Different and broken needles cause the needle-punched marks on the surface of the woolen blanket to be too deep, resulting in the problem of peaks and valleys. Therefore, it is necessary to use the subsequent smoothing process to eliminate the marks of needle-punched grooves. At present, the traditional grinding process is used to eliminate the needle-punched marks on the surface of the ring-shaped woolen blanket. Ho...

Problems solved by technology

At present, the traditional grinding process is used to eliminate the needle-punched marks on the surface of the ring-shaped woolen blanket. However, because the fibers on the surface of the woolen blanket are not easily broken, they are pulled out from the matrix during the grinding process, and fluff is formed on the surface after processing, and the peaks cannot be completely removed. Elimination, so that the leveling requirements cannot be met, its work efficiency is low, and product quality is difficult to guarantee
