Embodiment 1

[0062] like figure 1 and figure 2 As shown in the figure, a method and device for continuous impregnation of materials provided by the present invention includes the following steps: the material passes through the conveying device 101, the impregnated material is placed in the unwinding station, and the material is introduced into the preheating and humidifying device by the roller. 102. Heat, humidify and spray the material, so that the material can be immersed more fully, and then the material enters the immersion tank 111 of the immersion device for immersion. It is dye, varnish, penetrating ink, wax liquid, and the impregnating liquid can also be glue, such as melamine glue, urine glue, transparent resin glue, dye such as ink, or resin, such as wear-resistant resin, etc. After impregnation Through the rollers of the conveying device 101, it is transferred to the positive pressure or negative pressure device, see figure 2, This embodiment adopts an airflow air knife pr...

Embodiment 2

[0065] like image 3 , Figure 4 and Figure 5 , as shown, a method and device for continuous negative pressure impregnation provided by the present invention, the material is completed through the following steps and in the device, the main difference is that the negative pressure treatment step is completed before the impregnation step, and the negative pressure used in this embodiment is The processing device is a device for pressing rollers to seal negative pressure, and the specific steps are as follows: the material 302 passes through the conveying device, and the material is placed in the unwinding station 301, and the material is introduced into the preheating and humidifying device 303 by the roller to heat and humidify the material, In this way, the material can be impregnated more fully, and then the material enters the liquid storage chamber 318. The liquid storage chamber is vertical, and the liquid storage tank 316 is horizontal. The immersion liquid 317 is pla...

Embodiment 3

[0067] This embodiment is the combination of Embodiment 1 and Embodiment 2, and the details are as follows:

[0068] like figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 As shown, the present invention provides a continuous impregnation method and device, the material is completed through the following steps and in the following device, the main difference is that the negative pressure treatment step is completed before the impregnation step, and the negative pressure treatment used in this embodiment is The device is a device that seals negative pressure with a pressure roller, such as Figure 5 , the specific steps are as follows: the material passes through the conveying device, the material is placed in the unwinding station, the material is introduced into the preheating and humidifying device 501 by the roller, and the material is heated and humidified, so that the material can be impregnated more fully, and then The material enters the liquid storage cavi...

Abstract

The invention provides a method for continuous impregnation of materials. The method comprises the following steps: material conveying; material impregnation; material drying; material shearing; and material winding including positive pressure treatment and / or negative pressure treatment. The invention also provides a device for the material continuous impregnation method. The device includes a material conveying device, a negative pressure device, a dipping device, a drying device, a cutting device and a winding device, and the devices are connected in sequence. The material dipping device or the back thereof is provided with a positive pressure device and or the negative pressure device, so that various materials especially thick or special materials contain less air bubbles after impregnation and has better effect. The device achieves continuous vacuum impregnation and dyeing of various materials and has the advantage of no hurt to the materials. A complete casing design realizes the processes of material dipping, liquid immersion, paraffin immersion and double-side dyeing soaking without opening the casing.

Description

technical field [0001] The invention relates to the field of impregnation, in particular to a method and device for continuous impregnation of materials. Background technique [0002] At present, in the continuous impregnation of materials, there are problems of uneven printing and dyeing impregnation, impermeability, and bubbles in the impregnated or printed materials, especially when impregnating materials with different thicknesses, materials and special materials. SUMMARY OF THE INVENTION [0003] In order to solve the above technical problems, the present invention provides a method for continuous impregnation of materials, comprising the following steps: a material conveying step; a material impregnation step, a material drying step; a material shearing step; a material coiling step, the steps include Positive pressure treatment and or negative pressure treatment steps. [0004] Further, the step of performing negative pressure treatment on the material is performed...
