Description

Technical Field

[0001] This utility model belongs to the technical field of adhesive dispensing devices, and specifically relates to an adhesive dispensing device. Background Technology

[0002] Currently, there are two main methods for applying adhesive (for sealing) to "easy-open paper bags":

[0003] (1) Fiber optic induction adhesive spraying and dispensing method.

[0004] This adhesive dispensing device consists of an optical fiber amplifier, optical fiber, solenoid valve, air connector, and stainless steel pressure tank. The device is expensive to manufacture and purchase, and its use is limited by the sensing time, which is over 4 seconds per dispensing cycle, resulting in inflexible dispensing. Furthermore, the amount of adhesive dispensed is difficult to control flexibly during use, making it hard to guarantee the sealing quality of the packaging bags after application. It also frequently clogs the adhesive nozzle, further impacting production efficiency. Additionally, disassembly and cleaning of this device are particularly time-consuming, leading to high maintenance costs. Finally, this adhesive dispensing device is generally used on high-speed machines (600 SPM) with 2 channels per person.

[0005] (2) Use a brush to manually apply the glue.

[0006] Specifically, people use brushes to apply glue to the glue tank and then apply it to the opening of the paper bag. This method is labor-intensive for workers, with each application taking more than 3 seconds, and can only be used on high-speed machines (600 SPM) with 2 channels per person. In addition, the glue tank is completely open to facilitate glue dispensing, which causes the glue to evaporate and be lost easily, increasing the cost.

[0007] As can be seen from the above, there is currently a lack of a reliable and durable new glue-collecting device to facilitate glue collection and packaging, thereby improving production efficiency.

[0008] Therefore, a new technology is needed to address the lack of a reliable and durable new adhesive dispensing device in existing technologies. Utility Model Content
