Description

Technical Field

[0001] This utility model belongs to the field of electronic tape processing technology, and relates to a material container with adjustable adhesive viscosity. Background Technology

[0002] During the coating process on a thin film, the viscosity of the adhesive increases with continuous use due to solvent evaporation and other factors. To match the desired viscosity, it is necessary to add the appropriate amount of solvent based on the adhesive viscosity. This system uses a viscosity sensor to monitor the adhesive viscosity in real time. When it detects that the solvent is evaporating too quickly, causing an abnormal increase in viscosity, the system precisely adds the appropriate amount of solvent according to a pre-set program to maintain the adhesive viscosity within a suitable range. The current approach involves placing the sensor directly inside the container. When the detected viscosity is lower than the set value, a certain amount of solvent is added to the container, followed by stirring. This method requires stopping the adhesive output when adjusting the viscosity; otherwise, it can easily result in an unacceptable output adhesive viscosity. Furthermore, since the adhesive is in a static state when no solvent input is needed, it is prone to stratification during this process, resulting in a higher viscosity at the bottom of the container. In other words, the viscosity detected by the sensor at the sensor location is inconsistent with the actual viscosity of the adhesive after mixing inside the container. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a material tank with adjustable adhesive viscosity. The technical problem to be solved by this invention is how to improve the accuracy of adhesive viscosity adjustment.

[0004] The purpose of this utility model can be achieved through the following technical solution: a material tank with adjustable adhesive viscosity, characterized in that it includes a tank body with a top opening, a cover plate connected to the opening of the tank body, a return pipe detachably connected to the bottom of the cover plate, and a screw rotatably connected in the return pipe. The upper end of the screw is connected to the output shaft of a motor provided on the cover body. The upper end of the return pipe is provided with a discharge hole. The cover body is also provided with a solvent input pipe, and the outlet of the solvent input pipe is located in the return pipe.

[0005] Furthermore, the upper end of the return pipe has a cone, with the large-diameter end of the cone facing upwards, the discharge hole located on the wall of the cone, and the upper end of the screw is fixedly equipped with a stirring paddle located inside the cone.

[0006] Similar to the mixing principle of existing technologies, a viscosity sensor is installed inside the tank. When the detected viscosity is higher than the set value, a certain amount of solvent is fed into the cone through the solvent input pipe. The screw rotates, causing the material to flow from bottom to top in the return pipe and be initially mixed with the solvent in the cone. Then, it is discharged from the discharge hole into the material tank. The glue flows from top to bottom in the tank outside the return pipe, and from bottom to top in the return pipe, keeping the material in a continuous mixing state. When it is necessary to reduce the viscosity, the glue and solvent can be initially dispersed and mixed in the cone before being transported to the tank outside the return pipe for secondary mixing with other glues to be diluted. In this way, the glue can be continuously output without any significant increase or decrease in viscosity. Attached Figure Description

[0007] Figure 1 This is a schematic diagram of the adhesive liquid tank.

[0008] In the diagram, 1 is the tank body; 2 is the cover plate; 3 is the return pipe; 4 is the screw; 5 is the motor; 6 is the discharge port; 7 is the solvent input pipe; 8 is the cone; and 9 is the agitator. Detailed Implementation

[0009] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0010] like Figure 1 The adhesive viscosity adjustable container shown includes a container body 1 with a top opening, a cover plate 2 connected to the opening of the container body 1, a return pipe 3 detachably connected to the bottom of the cover plate 2, and a screw 4 rotatably connected inside the return pipe 3. The upper end of the screw 4 is connected to the output shaft of a motor 5 mounted on the cover body. The upper end of the return pipe 3 is provided with a discharge hole 6. The cover body is also provided with a solvent input pipe 7, and the outlet of the solvent input pipe 7 is located inside the return pipe 3.

[0011] The upper end of the return pipe 3 has a cone 8 with the large diameter end of the cone 8 facing upward. The discharge hole 6 is located on the wall of the cone 8. The upper end of the screw 4 is fixedly equipped with a stirring paddle 9 located inside the cone 8.

[0012] Similar to the mixing principle of existing technologies, a viscosity sensor is installed inside the tank 1. When the detected viscosity is higher than the set value, a certain amount of solvent is fed into the cone 8 through the solvent input pipe 7. The screw 4 rotates, causing the material to flow from bottom to top in the return pipe 3 and be initially mixed with the solvent in the cone 8. Then, it is discharged into the material tank through the discharge hole 6. The glue flows from top to bottom in the tank 1 outside the return pipe 3, and from bottom to top in the return pipe 3, so that the material is in a continuous mixing state. When it is necessary to reduce the viscosity, the glue and solvent can be initially dispersed and mixed in the cone 8, and then transported to the tank 1 outside the return pipe 3 for secondary mixing with other glues to be diluted. In this way, the glue can be continuously output, and there is no situation where the viscosity of the glue is significantly too high or too low during continuous output.

[0013] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
