[0014] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0015] Figure 1 It is a structural diagram of the present utility model.

[0016] As attached Figure 1 As shown, a precise glue-dispensing glue coating machine includes a glue valve 1, a glue pump 2, a glue delivery hose 3, a primary pressure regulating valve 4, a secondary pressure regulating valve 5, a pressure sensor 1 6, a pressure sensor 2 7, a pressure sensor 3 8, a heating mechanism 9, and a glue valve moving mechanism 10. The feed port of the glue valve 1 is connected to the glue pump 2 through the glue delivery hose 3. The glue delivery hose 3 is sequentially installed with a pressure sensor 1 6, a primary pressure regulating valve 4, a pressure sensor 2 7, a secondary pressure regulating valve 5, and a pressure sensor 3 8. The glue pump 2 is installed with a heating mechanism 9. The glue valve 1 is installed on the glue valve moving mechanism 10. The glue valve 1, the glue pump 2, the primary pressure regulating valve 4, the secondary pressure regulating valve 5, the pressure sensor 1 6, the pressure sensor 2 7, the pressure sensor 3 8, the heating mechanism 9, and the glue valve moving mechanism 10 are all electrically connected to a PLC.

[0017] The glue valve 1 is a screw valve.

[0018] The heating mechanism 9 includes a heating rod, a temperature controller, a temperature sensor, and a heating block. The heating rod and the temperature sensor are electrically connected to the temperature controller. The temperature sensor and several heating blocks are installed on the rubber delivery pipe 3, and the heating rod is installed on the rubber pump 2.

[0019] The glue valve moving mechanism 10 is a multi-axis manipulator, and the glue valve 1 is connected to the glue delivery pipe 3 through a hose.

[0020] The system works as follows: Glue pump 2 feeds glue from the raw material barrel to glue valve 1 at the front end of glue pipe 3. Glue valve 1 is a screw valve that controls the amount of glue discharged for precise application. A primary pressure regulating valve 4 and a secondary pressure regulating valve 5 maintain pressure within the glue pipe 3, reducing the impact of pressure on glue discharge. Pressure sensors 1 6, 2 7, and 3 8 monitor pressure changes in different sections of the glue pipe 3 in real time, transmitting signals to the PLC. If pressure exceeds the set value, the PLC activates an alarm.

[0021] The heating blocks of the heating mechanism 9 are sequentially distributed along different sections of the rubber pipe 3, providing uniform heating. Furthermore, a temperature sensor transmits real-time information about the glue temperature within the pipe to the PLC, which controls the start and stop of the heating mechanism 9 to ensure that the glue within the pipe 3 maintains the set temperature.

[0022] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
