[0023] Example:

[0024] To solve the above technical problems, such as Figures 1 to 2 As shown, this embodiment provides a glue circulation heating system, including: a box 1 with an internal accommodating space; a glue bucket 2 installed inside the box 1; and a glue dispensing mechanism installed inside the box 1, wherein the glue dispensing mechanism is connected to the glue bucket 2 to form a circuit.

[0025] The box 1 is used to house the various components. The control panel is set on the top of the box 1. The glue tank 2 is connected to the glue dispensing mechanism through pipelines and forms a circulation loop. The glue dispensing mechanism can maintain the fluidity of the glue in the loop and reduce blockage caused by glue deposition and solidification.

[0026] Furthermore, such as Figures 1 to 2As shown, the glue dispensing mechanism includes: a glue valve 3, installed inside the housing 1, with the glue outlet of the glue valve 3 connected to the liquid inlet of the glue tank 2; a pumping assembly, installed inside the housing 1, positioned between the liquid outlet of the glue tank 2 and the glue inlet of the glue valve 3; a circulation assembly, installed inside the housing 1, positioned between the liquid inlet of the glue tank 2 and the glue outlet of the glue valve 3; and a glue heater 4, positioned between the pumping assembly and the glue inlet of the glue valve 3.

[0027] The glue valve 3 is installed inside the upper part of the housing 1. The pumping component is installed between the liquid outlet of the glue tank 2 and the liquid inlet of the glue valve 3. The circulation component is installed between the liquid inlet of the glue tank 2 and the glue outlet of the glue valve 3. The glue heater 4 is located between the liquid outlet of the glue tank 2 and the glue inlet of the glue valve 3. The glue heater 4 is also equipped with a filter device to filter the glue flowing through the pumping component.

[0028] Furthermore, such as Figures 1 to 2 As shown, the pumping assembly includes: a pneumatic diaphragm pump 5, which is connected to the outlet of the glue tank 2, and the end of the pneumatic diaphragm pump 5 not connected to the outlet of the glue tank 2 is connected to the glue inlet of the glue valve 3; and a pressure stabilizing valve 6, which is disposed between the pneumatic diaphragm pump 5 and the glue inlet of the glue valve 3.

[0029] Among them, the pneumatic diaphragm pump 5 is connected to the liquid outlet of the glue tank 2. The pneumatic diaphragm pump 5 pumps the glue to the glue heater 4. The pneumatic diaphragm pump 5 drives the diaphragm to reciprocate through compressed air to realize fluid transportation. The pressure stabilizing valve 6 is set between the glue heater 4 and the glue inlet of the glue valve 3 to maintain the pressure stability in the circuit.

[0030] Furthermore, such as Figures 1 to 2 As shown, the circulation assembly includes: a flow control valve installed between the glue outlet of the glue valve 3 and the liquid inlet of the glue tank 2; and a circulation controller installed between the glue heater 4 and the glue inlet of the glue valve 3.

[0031] The flow control valve is located between the glue outlet of the glue valve 3 and the liquid inlet of the glue tank 2 to regulate the flow rate of the glue in the circuit; the circulation controller is installed between the glue inlet of the glue heater 4 and the glue valve 3 to achieve precise control of the glue temperature and circulation process, and reduce the risk of blockage of the glue valve 3.

[0032] Furthermore, such as Figures 1 to 2 As shown, it also includes: a pressure stabilizing pipeline, which is disposed between the pressure stabilizing valve 6 and the pneumatic diaphragm pump 5.

[0033] The pressure stabilizing pipeline includes an air inlet and a pressure regulating valve. The air inlet is connected to an external air source to provide driving power for the pneumatic diaphragm pump 5. The pressure regulating valve is used to adjust the air inlet pressure and control the operating frequency of the pneumatic diaphragm pump 5. The pressure stabilizing pipeline is mainly used to accurately control the power air source pressure of the pneumatic diaphragm pump 5 to ensure the stable operation of the pneumatic diaphragm pump 5.

[0034] Furthermore, such as Figures 1 to 2 As shown, it also includes a vacuum pump connected to the glue tank 2, which provides negative pressure to the internal environment of the glue tank 2.

[0035] The vacuum pump is connected to the glue tank 2 via a connector. It can extract the air from the pipe connected to the glue tank 2 and create a negative pressure to draw the glue in the glue tank 2 into the outlet.

[0036] Furthermore, such as Figures 1 to 2 As shown, it also includes: a pulse damper 7, which is connected to the pneumatic diaphragm pump 5.

[0037] The pulse damper 7 is installed at the outlet end of the pneumatic diaphragm pump 5 to eliminate the periodic fluctuations generated by the pneumatic diaphragm pump 5 during reciprocating motion and extend the service life of the pneumatic diaphragm pump 5.

[0038] In summary, the vacuum pump delivers the adhesive from the glue tank 2 to the pneumatic diaphragm pump 5, which then pumps the adhesive to the adhesive heater 4. The pressure fluctuation of the pneumatic diaphragm pump 5 is adjusted by the pulse damper 7. The adhesive is filtered by a filter device installed in the adhesive heater 4. A circulation controller is installed between the adhesive heater 4 and the adhesive valve 3 to control the adhesive temperature. The heated adhesive flows out of the pressure regulating valve 6, which adjusts the pressure of the adhesive in the pipeline before entering the adhesive valve 3 for application. When the nozzle of the adhesive valve 3 is not working, the unapplied adhesive returns to the glue tank 2 through the outlet. The flow rate of the adhesive returning to the glue tank 2 is controlled by the flow controller. This cycle repeats to ensure that the adhesive flows continuously in the loop, preventing adhesive sedimentation and reducing the risk of clogging of the adhesive valve 3.

[0039] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope described in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
