[0030] The above scheme is further described below in conjunction with specific examples. It should be understood that these examples are used to illustrate the utility model and are not limited to the scope of the utility model. The implementation conditions used in the examples can be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0031] like Figure 1 , which is a schematic diagram of the structure of an embodiment of the utility model, provides an anti-sedimentation glue coating device, including a glue coating mechanism, a glue tank mechanism, a glue supply mechanism and a glue liquid circulation mechanism.

[0032] The gluing mechanism is used to complete the gluing of material 8 (such as paper or fiber fabric, etc.), including a frame (not shown), a gluing roller assembly and a metering roller assembly arranged on the frame. The material 8 passes through the gluing roller assembly and then passes out through the metering roller assembly.

[0033] The dipping roller assembly includes an upper dipping roller 1 and a lower dipping roller 2 located obliquely below the upper dipping roller 2. The metering roller assembly includes a pair of metering rollers 3 arranged above the lower dipping roller 2. The material 8 passes through the upper dipping roller 1 and the lower dipping roller 2 in sequence and then passes through the pair of metering rollers 3, thereby completing quantitative gluing.

[0034] The glue tank mechanism includes a glue tank 4 and a lifting assembly that drives the glue tank 4 to move up and down. The glue tank 4 has a working position and a non-working position arranged up and down when driven by the lifting assembly. When the glue tank 4 is located at the working position, the glue dipping roller assembly is located in the glue tank 4 to complete the gluing of the material 8. When the glue tank 8 is located at the non-working position, the glue tank 4 is away from the glue dipping roller assembly.

[0035] The glue supply mechanism is used to supply glue to the glue tank 4, including a glue storage tank 9 located above the glue tank 4 and a stirring component arranged on the glue storage tank 9. A glue supply pipe 12 is connected to the bottom of the glue storage tank 9, and the glue in the glue storage tank 9 can flow into the glue tank 4 through the glue supply pipe 12. A glue supply port 9-1 and an inorganic powder adding port 9-2 are provided at the upper end of the glue storage tank 9, which are used to add glue and inorganic powder to the glue storage tank 9 respectively.

[0036] Among them, the stirring component includes a stirring motor 10 arranged at the upper end of the glue storage tank 9 and a stirring paddle 11 connected to the stirring motor 10. The stirring paddle 11 is driven by the stirring motor 10 to rotate to stir the glue liquid in the glue storage tank 9 to avoid precipitation of inorganic powder.

[0037] In order to facilitate automatic glue supply to the glue tank 4, a liquid level sensor 14 is provided in the glue tank 4, and a switch valve 13 is provided on the glue supply pipe 12. The liquid level sensor 14, the switch valve 13 and the control unit 15 are connected by signal. The liquid level in the glue tank 4 is monitored in real time by the liquid level sensor 14. When the liquid level sensor 14 detects that the amount of glue in the glue tank 4 is lower than the lower limit setting value, the liquid level sensor 14 transmits a low liquid level signal to the control unit 15. The control unit 15 opens the switch valve 13 on the glue supply pipe 12 to supply glue to the glue tank 4 until the liquid level sensor 14 detects that the amount of glue in the glue tank 4 reaches the upper limit setting value. The liquid level sensor 14 sends a signal, and the control unit 15 closes the switch valve 13 to stop supplying glue.

[0038] The glue liquid circulation mechanism is used to circulate and stir the glue liquid in the glue tank 4, including a glue spraying pipe 7 arranged in the glue tank 4 away from one end of the metering roller assembly, a circulation pipeline 5 connecting the bottom of the glue tank 4 and the glue spraying pipe 7, and a circulation pump 6 arranged on the circulation pipeline 5. The glue liquid at the bottom of the glue tank 4 is circulated to the glue spraying pipe 7 through the circulation pump 6, and then sprayed into the glue tank 4 through the glue spraying pipe 7, so as to realize the circulation stirring of the glue liquid and avoid the precipitation of inorganic powder in the glue liquid.

[0039] In this example, the side of the glue groove 4 from the glue spraying tube 7 to the bottom is an inclined surface 4-1 arranged at an angle downward, and the supporting surface of the glue dipping roller assembly for the material 8 is parallel to the inclined surface 4-1, that is, the extension direction of the material 8 on the glue dipping roller assembly is parallel to the inclined surface 4-1, and the glue spraying direction of the glue spraying tube 7 is consistent with the moving direction of the material 8 and is parallel to the inclined surface 4-1.

[0040] During the dipping process, there is a certain gap between the material 8 and the inner side of the glue tank 4. The glue in the glue spraying tube 7 is sprayed out along the running direction of the material 8. The sprayed glue flows close to and parallel to the inner wall of the glue tank 4, and continuously flushes the inner surface of the glue tank 4 to prevent the deposition of inorganic particles. The front side of the inclined glue tank 4 maintains a certain gap H with the running material 8. The glue sprayed from the glue spraying tube 7 not only flushes the inner side of the glue tank 4, but also stirs the glue in the gap layer to prevent the precipitation of powder particles. A reasonable gap ensures that the glue is stirred and flows quickly, and at the same time does not affect the smooth operation of the material, thereby ensuring product quality.

[0041] In order to prevent the inorganic powder from depositing at the bottom of the glue tank 4, the gap h between the lower dipping roller 2 and the bottom of the glue tank 4 is smaller than H, so that the glue here flows faster, effectively preventing the inorganic powder particles from depositing at the bottom. At the same time, part of the glue sprayed from the glue spraying tube 7 flows to the upper part of the glue tank on both sides of the width of the material 8, driving the glue in the glue tank 4 to flow, so that the powder particles are evenly dispersed in the glue.

[0042] The lifting assembly includes a base 16, a stretching member 18 connected to both ends of the base 16, a support roller 17 supporting the stretching member 18, and a cylinder 19 connected to the stretching member 18. The lower end of the stretching member 18 is connected to the base 16, and the upper end of the stretching member 18 extends in the horizontal direction after bypassing the support roller 17. The driving direction of the cylinder 19 is arranged in the horizontal direction. The stretching member 18 is pulled by the cylinder 19 to drive the base 16 to move up and down, thereby driving the rubber tank 4 to achieve lifting.

[0043] The working principle of the utility model is:

[0044] The material 8 passes through the upper and lower glue dipping rollers 1 and 2 in sequence, and then passes between a pair of metering rollers 3. The glue tank 4 is lifted to the working position by the lifting assembly. The control unit 15 opens the switch valve 13. The glue in the glue storage tank 9 flows into the glue tank 4 through the glue supply pipe 12. When the liquid level sensor 14 detects that the liquid level in the glue tank 4 reaches the upper limit setting value, the switch valve 13 is closed, the glue supply is stopped, and the gluing mechanism starts to work. The material 8 moves in the glue tank 4. The glue at the bottom of the glue tank 4 flows back to the glue spraying pipe 7 through the circulation pipeline 5, and the glue is sprayed out through the glue spraying pipe 7 to avoid the precipitation of inorganic powder and make the glue evenly impregnated into the surface of the material 8.

[0045] In summary, the glue coating device can prevent the inorganic powder from settling in the glue solution, ensure that the glue solution is evenly impregnated into the material surface, and ensure product quality.

[0046] The above examples are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
