[0004] The aforementioned patent describes the functional structure of a hot melt glue machine. In practical applications, the glue dispensing device of the hot melt glue machine is connected to the glue tank through a supply pipeline to continuously supply glue to the dispensing device. However, the glue tank generally does not have a quantitative function, making it difficult to ensure the consistency of the glue supply. This results in inconsistent glue dispensing amounts in different batches, affecting processing accuracy. Therefore, we propose a hot melt glue machine with quantitative glue supply to solve the above problems. Utility Model Content

Detailed Implementation

[0020] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0021] Please see Figure 1 This utility model provides a hot melt glue machine for quantitative glue supply, including a glue injection device 1, a material supply pipeline 2 and a quantitative glue supply device 3. The top port of the glue injection device 1 is connected to the material supply pipeline 2, and the end of the material supply pipeline 2 is connected to the quantitative glue supply device 3.

[0022] Please see Figure 2-4 This utility model provides a hot melt glue machine with quantitative glue supply. The quantitative glue supply device 3 includes a frame 31, a main glue tank 32, a feeding pipe 33, a pneumatic actuator 34, a piston part 35, a secondary glue tank 36, and a solenoid valve 37. The main glue tank 32 is installed on the right side of the inner bottom surface of the frame 31. The feeding pipe 33 is connected to the lower end of the surface of the main glue tank 32 and connects to the inside of the main glue tank 32. The pneumatic actuator 34 is installed on the top of the frame 31. The piston part 35 is sealed and slidably arranged inside the main glue tank 32. The bottom telescopic end of the pneumatic actuator 34 enters the inside of the main glue tank 32 and is installed and connected to the piston part 35. The secondary glue tank 36 is installed on the left side of the inner bottom surface of the frame 31. The secondary glue tank 36 is arranged side by side with the main glue tank 32. The end of the feeding pipe 2 is connected to the secondary glue tank 36. The main glue tank 32 and the secondary glue tank 36 are connected by a solenoid valve 37.

[0023] Specifically, during use, the main glue tank 32 is replenished with glue through the feeding pipe 33. Then, the pneumatic actuator 34 is activated and the solenoid valve 37 is opened. The pneumatic actuator 34 drives the piston 35 to press down a predetermined stroke, causing the glue inside the main glue tank 32 to flow into the auxiliary glue tank 36 under pressure. Finally, the solenoid valve 37 is closed, and a predetermined amount of glue is stored inside the auxiliary glue tank 36. This allows the auxiliary glue tank 36 to provide a quantitative amount of glue to the glue dispensing device 1 through the feeding pipe 2, ensuring the consistency of the glue dispensing amount from the glue dispensing device 1.

[0024] Specifically, a main observation window 38 is provided on the front of the main glue tank 32, with a height dimension of not less than 50% of the height dimension of the main glue tank 32. The main observation window 38 allows viewing of the glue content inside the main glue tank 32, so that timely replenishment can be made through the feeding pipe 33. A secondary observation window 39 is provided on the front of the secondary glue tank 36, with a height dimension of not less than 90% of the height dimension of the secondary glue tank 36. The secondary observation window 39 allows viewing of the glue supply status of the secondary glue tank 36, so that timely adjustments can be made based on the redundancy of the glue supply. Capacity scales are provided on the surfaces of the main observation window 38 and the secondary observation window 39 for a more intuitive understanding of the glue content inside the main glue tank 32 and the secondary glue tank 36.

[0025] To further explain, a one-way valve 331 is installed at the end of the feeding pipe 33 that connects to the main glue tank 32, ensuring that the glue inside the feeding pipe 33 can only flow in one direction, and preventing the glue inside the main glue tank 32 from flowing back into the feeding pipe 33 when the piston part 35 applies pressure.

[0026] To further explain, an electric heating wire 310 is installed on the bottom inner side of the auxiliary glue tank 36. The electric heating wire 310 can provide heating and insulation for the glue inside the auxiliary glue tank 36, thereby ensuring the fluidity of the glue and ensuring smooth glue supply to the auxiliary glue tank 36.
