Description

Technical Field

[0001] The utility model relates to the field of fiber substrate modification, in particular to a continuous spraying device for sheet material liquid-powder mixing. Background Art

[0002] In order to improve the performance of fiber materials, titanium dioxide is used to modify the fiber substrate during the production process. At present, titanium dioxide is mixed on the fiber substrate by rolling coating. This mixing method has some problems in the actual production process, mainly including the following aspects: First, the substrate will be deformed during the rolling process, resulting in a thinner thickness of the original substrate; second, the bottom surface cannot be completely penetrated during the rolling and scraping process, which affects the penetration of titanium dioxide in the substrate, resulting in different stability on the front and back of the material; third, the waste of rolling coating glue is large, and a large amount of surplus needs to be invested in the actual production process, increasing the cost of raw materials; fourth, the cleaning is cumbersome, and the cleaning time of residual glue on the equipment is long during the production process. Due to the characteristics of the mixed liquid, the cleaned mixed liquid cannot be used again.

[0003] Based on the above analysis, the present application provides a continuous spraying device for sheet material liquid-powder mixing, which is easy to operate and does not cause deformation of the substrate. Summary of the invention

[0004] The embodiment of the present application provides a continuous spraying device for sheet material liquid-powder mixing, so as to solve the problem in the related art that mixing titanium dioxide on a fiber substrate by a rolling coating method may cause rolling deformation of the substrate.

[0005] In a first aspect, the present application provides a continuous spraying device for sheet material liquid-powder mixing, comprising:

[0006] A base bracket, a conveyor belt for conveying a substrate is placed on the base bracket, and a proximity switch is arranged on the base bracket;

[0007] A material cylinder, the material cylinder is used to inject glue and titanium dioxide powder, the material cylinder is connected to an adjustment bracket, the adjustment bracket is connected to a base bracket, an air jet is installed in the material cylinder; a valve is arranged on the air jet, and the switch of the valve is controlled by a proximity switch;

[0008] The spray barrel is installed at the bottom of the material cylinder, a plurality of discharge ports are arranged at the bottom of the spray barrel, the bottom of the injection pipe extends into the spray barrel, and the injection pipe is filled with compressed gas.

[0009] In some embodiments, the proximity switch is located directly below the spray barrel, and when the substrate is transported to the position of the proximity switch by the conveyor belt, the proximity switch sends a signal to open the valve. After the valve is opened, the compressed gas in the jet pipe flows out, and under the action of the compressed gas, the uniformly mixed glue and titanium dioxide powder are sprayed from the discharge port onto the substrate.

[0010] In some embodiments, a gas injection port is provided on the side of the gas injection pipe, and the gas injection port is connected to a gas storage tank storing compressed gas.

[0011] In some embodiments, a feeding port is provided on the side of the material cylinder, and the feeding port is connected to a feeding pipe, through which the glue solution and titanium dioxide powder are added into the material cylinder.

[0012] In some embodiments, a stirring shaft is provided in the material cylinder, and the stirring shaft is used to stir the titanium dioxide powder and the glue evenly.

[0013] In some embodiments, a splash shield is provided on the outside of the spray barrel to prevent material from splashing during the spraying process and reduce the workload of cleaning after production.

[0014] In some embodiments, the air injection pipe is Y-shaped.

[0015] In some embodiments, the substrate is a ceramic fiber sheet.

[0016] The beneficial effects of the technical solution provided by this application include:

[0017] 1. When the continuous spraying device provided by the present application is used, the substrate is in a static conveying state, and the spraying of glue will not affect the deformation of the substrate;

[0018] 2. Titanium dioxide powder has a high specific gravity. After being dispersed in the glue, it is difficult for the titanium dioxide powder to evenly penetrate into the interior of the substrate due to the surface tension of the glue. The continuous spraying device provided in this application can allow the titanium dioxide powder to enter the interior of the substrate with a certain kinetic energy, and the glue and titanium dioxide powder contact the substrate in the form of a spray, which saves raw materials compared to the rolling and scraping method.
