[0002] In industrial production, adhesive spraying equipment is widely used in the bonding processes of various products. As a core component of adhesive spraying equipment, the performance of the adhesive metering system directly affects the quality of adhesive application and production efficiency. Currently, existing glue supply metering systems for spray adhesive equipment have several problems. On the one hand, the glue supply metering is not precise enough, making it difficult to accurately control the glue quantity, resulting in too much or too little glue at the bonding points of the products, affecting product quality. On the other hand, the glue supply process is unstable, prone to glue interruptions or fluctuations in glue quantity, reducing production efficiency. Furthermore, some glue supply metering systems are structurally unstable, and problems such as loosening of components are likely to occur during long-term use, shortening the equipment's lifespan and increasing maintenance costs. Therefore, those skilled in the art provide a glue supply metering system for spray adhesive equipment to solve the problems mentioned in the background art. Summary of the Invention

Detailed Implementation

[0018] Please see Figures 1-2 In this embodiment of the invention, a glue supply and metering system for a glue spraying device includes a glue storage tank 4 for storing glue. An electronic scale 2 is installed at the lower end of the tank, which can weigh the glue in the storage tank 4 in real time for accurate glue measurement. Support feet 1 are installed at each of the four corners of the bottom of the electronic scale 2, providing support for the entire system and ensuring its stability. The glue storage tank 4 and the electronic scale 2 are fixed together by a fixing seat 3. There are four sets of fixing seats 3, which surround the glue storage tank 4. Through the fixing effect of the four sets of fixing seats 3, the glue storage tank 4 is stably installed on the electronic scale 2, preventing it from shaking during use. A lid 6 is installed at the top of the glue storage tank 4. The lid 6 is used to seal the glue storage tank 4 to prevent the glue from being contaminated or evaporating. The glue storage tank 4 and the lid 6 are connected by a lid fixing structure 5. There are four sets of lid fixing structures 5 to ensure that the glue storage tank 4 and the lid 6 are firmly connected. The lid fixing structure 5 includes a barrel body connecting ear 14, a rotating shaft 15, a connecting rod 16, a lid connecting ear 17, and a rotating nut 18. The barrel body connecting ear 14 is installed on the glue storage barrel 4, and the lid connecting ear 17 is installed on the side wall of the lid 6. The barrel body connecting ear 14 and the lid connecting ear 17 are fixed to the glue storage barrel 4 and the lid 6 respectively by welding. The welding connection method makes the connection between the two more firm and reliable. A rotating shaft 15 is rotatably connected to the inner side of the barrel connecting ear 14. A connecting rod 16 is connected to the upper end of the rotating shaft 15. A rotating nut 18 is sleeved on the upper end of the connecting rod 16. The outer surface of the connecting rod 16 is threaded, and the rotating nut 18 is threaded to the connecting rod 16. The length of the connecting rod 16 is greater than the distance between the barrel connecting ear 14 and the barrel lid connecting ear 17. When the barrel lid 6 needs to be placed on the glue storage barrel 4, rotate the connecting rod 16 so that the connecting rod 16 passes through the barrel lid connecting ear 17, and then tighten the rotating nut 18 to fix the barrel lid 6 to the glue storage barrel 4. When the barrel lid 6 needs to be opened, loosen the rotating nut 18 and rotate the connecting rod 16 to disengage it from the barrel lid connecting ear 17. The operation is convenient. A glue pump 7 is installed at the upper end of the lid 6. The glue pump 7 provides power for the delivery of glue and draws out the glue from the storage tank 4. A pressure gauge 8 is installed at the upper end of the lid 6, located to one side of the glue pump 7. The pressure gauge 8 is used to monitor the pressure during the glue supply process, so that the operator can understand the glue supply pressure in real time and make timely adjustments to ensure stable glue supply pressure. A lifting handle is also installed at the top of the bucket lid 6, which makes it convenient for operators to open and close the bucket lid 6. One end of the glue pump 7 is connected to the glue spraying device through the glue hose 9. After the glue is drawn out by the glue pump 7, it is delivered to the glue spraying device through the glue hose 9.

[0019] The glue spraying device includes a connecting mounting arm 10, a fixing frame 11, and a glue spraying gun 12. The connecting mounting arm 10 is mounted on an external automated robotic arm, which can drive the glue spraying device to move, realizing automated glue spraying operation. A fixing frame 11 is provided at one end of the connecting mounting arm 10. The glue spraying gun 12 is installed inside the fixing frame 11. The fixing frame 11 fixes the glue spraying gun 12 to ensure stable operation of the glue spraying gun 12. Two glue spray guns 12 are provided, which can perform glue spraying operations simultaneously to improve glue spraying efficiency. Each glue spray gun 12 is connected to an air hose 13, one end of which is connected to an electric proportional valve. The electric proportional valve can adjust the air pressure as needed, thereby controlling the glue spraying volume and speed of the glue spray gun 12, further improving the accuracy of glue spraying. The working process of this utility model is as follows: First, the glue is poured into the glue storage tank 4, and the lid 6 is placed on top. The lid 6 is then securely fixed to the glue storage tank 4 using the lid fixing structure 5. The electronic scale 2 weighs the glue in the glue storage tank 4 in real time and feeds the data back to the control system. Start the glue pump 7, which extracts the glue from the glue storage tank 4 and delivers it to the glue spray gun 12 of the glue spraying device via the glue hose 9. During the glue supply process, the pressure gauge 8 monitors the glue supply pressure in real time. The operator can adjust the operating parameters of the glue pump 7 through the control system based on the display of the pressure gauge 8 to ensure stable glue supply pressure. An external automated robotic arm moves the glue spraying device to the designated glue spraying position. An electric proportional valve adjusts the air pressure in the air pipe 13 according to the preset glue spraying parameters, thereby controlling the glue spraying amount and speed of the glue spraying gun 12. The two glue spraying guns 12 perform glue spraying operations simultaneously to complete the glue spraying operation on the product. Throughout the glue spraying process, the electronic scale 2 continuously monitors the changes in glue weight. Combined with parameters such as spraying time, it can accurately calculate the actual amount of glue sprayed, facilitating precise control and adjustment of the glue spraying process and ensuring the glue spraying quality of the product.
