[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0023] like Figures 1-2 As shown, the solid glue cooking and adding device includes a starch dissolving tank 1 and a solid glue dissolving and cooking tank 2.

[0024] The starch dissolving tank 1 is equipped with a feeding device 7 at the top, which is used to temporarily store starch. The starch dissolving tank 1 is connected to a pure water pipeline 6. The pure water pipeline 6 has a branch line connected to a pure water preheater 8. The starch dissolving tank 1 is equipped with a radar level gauge 12, and the bottom of the starch dissolving tank 1 is equipped with a stirrer 13.

[0025] The feeding device 7 includes a storage funnel 708 and a feeding body 701. The feeding body 701 is inverted cone shape. The top of the feeding body 701 is connected to a motor 702. The lower part of the motor 702 is connected to a support screw 703. The support screw 703 is located at the center of the feeding body 701. Spiral blades 704 are arranged around the support screw 703.

[0026] The feeding body 701 has a connection port at the top that connects to the storage funnel 708. An upper control valve 707 is provided at the connection port. A top cover 709 is provided at the top of the storage funnel 708. A pipe 706 is provided at the bottom of the feeding body 701 that connects to the starch dissolving tank 1. A bottom control valve 705 is provided on the pipe 706.

[0027] The quantitative buffer tank 3 has a double-layer structure, including an inner tank 301 and an outer jacket 302. The inner tank 301 is used to store solid glue solution, and the outer jacket 302 is connected to the steam pipeline 9. A radar level gauge 12 and a vent valve 14 are installed on the top of the quantitative buffer tank 3.

[0028] The steam pipeline 9 is connected to the solid glue dissolving cooking tank 2 and the starch cooking tank 5. The connected pipelines extend into the tank body, and steam nozzles 16 are provided at the outlets of the pipelines.

[0029] The quantitative buffer tank 3 is connected to the starch dilution tank 4 through the bottom outlet. A screw pump 10 is installed on the connecting pipeline, and a viscosity monitoring device 11 is installed on the top of the starch dilution tank 4.

[0030] The starch cooking tank 5 is equipped with a stirrer 13 at the bottom and a viscosity monitoring device 11 at the top. The starch cooking tank 5 is also equipped with a pipeline connected to a pure water preheater 8.

[0031] Both the starch dilution tank 4 and the solid glue dissolving and cooking tank 2 are equipped with pipelines connected to the pure water preheater 8 at the top. Both the starch dilution tank 4 and the solid glue dissolving and cooking tank 2 are equipped with a stirrer 13 at the bottom. The solid glue dissolving and cooking tank 2 is equipped with a radar level gauge 12 at the top.

[0032] The solid glue storage tank 15 is equipped with a stirrer 13 at the bottom and a radar level gauge 12 at the top.

[0033] The solid glue cooking and adding device of this utility model operates simultaneously in both the starch cooking section and the solid glue cooking section. First, in the starch cooking section, purified water is added to the starch dissolving tank 1, and a certain amount of starch is placed in the feeding device 7. At this time, the bottom control valve 705 is closed, and the amount of purified water added can be controlled by the radar level gauge 12. Simultaneously, the stirrer 13 is turned on, and the upper control valve 707 is opened, allowing the starch in the storage funnel 708 to be placed into the feeding body 701. Then, the motor 702 is turned on, starting the spiral device (spiral blades 704), and the bottom control valve 705 is opened, slowly adding the starch into the starch dissolving tank 1. This process controls the starch addition speed to prevent excessive addition of starch. To address the localized clumping and sticking to the walls that may occur, add amylase after the starch is added and stir until homogeneous. Then, transfer the liquid from the starch dissolving tank 1 to the starch cooking tank 5, stir, and introduce steam to heat and cook. The steam enters the tank through the steam nozzle 16, ensuring full contact with the liquid while working in conjunction with the stirrer 13 to ensure uniform mixing. Simultaneously, monitor the viscosity using the viscosity monitoring device 11. If the viscosity becomes too high, open the pipeline connected to the pure water preheater 8 for rapid dilution to prevent accidents. The cooked starch is then transferred to the starch dilution tank 4 and stirred for later use.

[0034] Secondly, in the solid glue cooking section, pure water is added to the solid glue dissolving and cooking tank 2, the stirrer 13 is turned on, a bag of solid glue is added from the top feeding port, steam is introduced to heat and cook, after cooking, water is added again to the set liquid level, and stirring and heat preservation are carried out; the heat preservation solid glue solution is transported to the solid glue storage tank 15 and kept warm for later use.

[0035] Finally, the solid glue solution in the solid glue storage tank 15 is pumped to the metering buffer tank 3 via the screw pump 10. The amount of solid glue solution transferred is quantitatively controlled by the radar level gauge 12 on both the solid glue storage tank 15 and the metering buffer tank 3. The solid glue solution is then quantitatively pumped to the starch dilution tank 4 to mix with the starch solution. The metering buffer tank 3 is equipped with a vent valve 14 and a radar level gauge 12 at its top. The metering buffer tank 3 includes an inner tank 301 and an outer jacket 302. The outer jacket 302 only provides insulation. All inlet and outlet pipelines for the solid glue solution extend into the inner tank 301. During the solid glue solution transportation process, if the radar level gauge 12 on the metering buffer tank 3 registers abnormal data, both screw pumps 10 at both ends will shut down, and the vent valve 14 will open in conjunction to ensure the pressure difference between the inside and outside of the metering buffer tank 3 is balanced, preventing system-wide damage. During the mixing process of solid adhesive solution and starch solution, the viscosity is monitored by viscosity monitoring device 11. The need for water replenishment can be controlled according to the real-time viscosity, so as to ensure the viscosity of the adhesive solution during the preparation process and guarantee the quality of the adhesive solution.
