[0008] Preferably, two holes are arranged on the barrel cover, and are respectively used for connecting a feeding pipe and a vacuum pipe.

[0009] Compared with the prior art, the utility model has the beneficial effects that:

[0010] 1.

[0016] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0017] This utility model provides a vacuum glue dispensing pump, such as Figs. 1-3 As shown, the device includes a glue bucket 1, with a detachable lid 2 on top. Two piston cylinders 4 are located at the bottom of the glue bucket 1, each connected to a valve 5. The outlets of the two valves 5 are connected to a common glue outlet 6. Two air cylinders 3 are located on the top of the lid 2. An extension rod 7 is connected to the piston end of each air cylinder 3, with the bottom of the extension rod 7 penetrating the lid 2 and connecting to the piston inside the piston cylinder 4. The air cylinders 3 and extension rods 7, in conjunction with the piston cylinders, pump and pressurize the glue stored in the glue bucket 1 into the piston cylinder 4, where it is then discharged through the valves 5 and the glue outlet 6, thus performing the glue dispensing process within the glue bucket 1 under vacuum. Initially, the extension rod 7 lifts the piston inside the piston cylinder 4, allowing the glue to flow into the piston cylinder 4 under gravity. During dispensing, the air cylinders drive the extension rod 7 downwards, squeezing the glue inside the piston cylinder 4 and forcing it through the valves 5 to the glue outlet 6, completing the glue dispensing process.

[0018] The cylinder 3, extension rod 7, and piston cylinder 4 are arranged in a one-to-one correspondence, and the two cylinders 3 move back and forth alternately to achieve continuous glue application. The two cylinders 3 operate independently and alternately. When one cylinder drives the extension rod 7 and piston cylinder 4 to move for conveying, the other cylinder 3 drives the extension rod to return to its original position. The alternating operation achieves continuous material conveying.

[0019] The lid 2 has two holes, which are used to connect the feeding pipe and the vacuum pipe respectively. The feeding pipe is connected to the glue storage source for feeding, and the vacuum pipe is used to connect to the vacuum pump for vacuum treatment inside the bucket, realizing integrated operation of feeding, vacuuming and glue application, which greatly improves the practicality of the lid device.
