Description

Technical Field

[0001] The present invention relates to the technical field of fabric coating application, and particularly to a preparation device for coated fabrics. Background Art

[0002] A fabric is a textile formed by crossing, winding, and connecting fine and long objects. A coated fabric is a fabric with a coating applied on the surface of an ordinary fabric. According to the functionality of the coating, coated fabrics can achieve special functions such as waterproofing, water pressure resistance, air permeability and moisture permeability, flame retardancy and stain resistance, and light shielding and reflection. At present, when coating fabrics, a textile coater is mainly used for the work;

[0003] For example, the Chinese invention patent with the authorization announcement number CN211026878U discloses a device for textile coating processing. The textile coating processing device includes a coating box. A feeding hole is opened on the left side of the coating box, and a discharging hole is opened on the right side of the coating box. Both sides of the bottom of the inner cavity of the coating box are fixedly connected with flattening mechanisms. Both sides of the top of the inner cavity of the coating box are fixedly connected with fixing frames II. The bottom of the fixing frame II is movably connected with a guide roller through a rotating shaft.

[0004] This textile coating processing device can perform coating operations on both sides simultaneously, but can only perform single coating, which is prone to the situation of less coating slurry being applied, and it is easy to have coating defects in some positions, such as the situation of voids in the coating; in addition, in order to achieve its special functionality, the current coating often adds some water-insoluble powders, such as nano-silver powder for sterilization, etc. Since these powders are insoluble in water, when preparing the coating slurry, only through stirring and mixing, the water-insoluble powders cannot be evenly dispersed in the slurry, resulting in uneven content of the coating and the phenomenon of functional defects in the coating at some positions.

[0051] Embodiment 4:

[0052] Please refer to Figures 1-11, which is the fourth embodiment of the present invention. Based on the above three embodiments, when the present invention is used, the unwinding reel 6 covered with the fabric cloth 8 is installed on the lower driving roller 4. Then, the fabric cloth 8 is arranged at each roller position, and then the preparation work is carried out. Water and water-soluble materials are added into the mixing chamber 24 through the feeding pipe 210 as the base slurry, and are stirred evenly by the stirring assembly 23. Then, the water-insoluble functional powder is added into the cartridge 223 of the uniform feeding assembly 22. During the stirring of the base slurry, the uniform feeding assembly 22 evenly scatters the powder for mixing. The prepared slurry is pumped into the slurry supply assembly 32 by the discharge pump 211. The slurry supply assembly 32 performs coating through the main coating blade 33 and the auxiliary coating blade 34. After the coating is completed, the fabric cloth 8 enters the drying tunnel 12 for drying and is wound up at the winding reel 5. The present invention performs two coatings on the fabric surface. The main coating blade 33 first performs the first coating. Since it is below, more coatings will be applied under the action of gravity. Then, the fabric cloth 8 moves to the auxiliary coating blade 34 for the second coating. The auxiliary coating blade 34 faces the top surface and will not apply too many coatings. Its function is to supplement the positions where the coating is not completely applied and fill the positions where there are gaps in the coating, thus avoiding the situation of void defects in the coating. In the preparation component 2 of the present invention, a uniform feeding assembly 22 is specifically provided for the water-insoluble functional powder. When it works, the housing 221 rotates, and at the same time, the material scattering block 228 reciprocates horizontally, so as to ensure uniform material scattering on the plane of the mixing chamber 24, without any material scattering blind area, thereby ensuring the uniformity of the dispersion of these powders in each position of the slurry, and further improving the more uniform dispersion of the functional powder in the final coating, and ensuring that the coatings in each area have good functionality.

[0053] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
