[0028] A connecting pipe 3 is installed at the bottom of the first material barrel 1 and the second material barrel 2. The connecting pipe 3 is connected to the mixing barrel 4. One end of the rubber hose 5 is connected to the mixing barrel 4, and the other end is connected to the glue gun 8. The glue gun 8 is detachably connected to the adjustment mechanism 7, and the adjustment mechanism 7 is arranged on the bracket 6.

[0029] The mixing barrel 4 includes a barrel body 40 , a motor 41 , a turntable 42 and a rotating shaft 43 . The motor 41 is installed above the barrel body 40 , an output end of the motor 41 is connected to the rotating shaft 43 , and the turntable 42 is installed on the rotating shaft 43 .

[0030] like Figure 2 As shown, the first material barrel 1 includes a material storage chamber 11 and a pre-storage chamber 12, a solenoid valve is connected between the material storage chamber 11 and the pre-storage chamber 12, a piston 13 is installed in the material storage chamber 11, and the upper end of the piston 13 is connected to a push rod 14.

[0031] An electronic scale 15 is installed at the bottom of the pre-storage chamber 12 , and scale lines are set on the pre-storage chamber 12 .

[0032] like Figure 3 As shown, the turntable 42 includes a turntable ring 421, a connecting sleeve 422, a supporting rib 423, and a rotating blade 424; the connecting sleeve 422 is sleeved on the rotating shaft 43, one end of the supporting rib 423 is connected to the connecting sleeve 422, and the other end is connected to the inner side of the turntable 42; the rotating blade 424 is installed on the supporting rib 423, and the supporting rib 423 and the rotating blade 424 are rotatably connected.

[0033] like Figure 4 As shown, the adjustment mechanism 7 includes a first sliding cylinder 71 , a second sliding cylinder 72 and a mounting platform 73 . The first sliding cylinder 71 is mounted on the bracket 6 , and its output end is connected to the second sliding cylinder 72 ; the output end of the second sliding cylinder 72 is connected to the mounting platform 73 .

[0034] The glue dispensing gun 8 is provided with a glue dispensing valve.

[0035] In the AB glue dispensing machine, the piston that pushes the glue is usually made of a material that can resist chemical corrosion, has good wear resistance and a low friction coefficient. This is because the piston needs to be in direct contact with the glue during work, and it also needs to withstand the pressure applied by air pressure or mechanical devices to ensure that the glue can be accurately and smoothly pushed out of the barrel. The piston 13 is made of stainless steel or polytetrafluoroethylene. Stainless steel is often used to make pistons because of its excellent corrosion resistance and mechanical strength, especially food grade or medical grade stainless steel, which can also meet more stringent hygiene standards. Teflon PTFE, polytetrafluoroethylene: Polytetrafluoroethylene has excellent chemical inertness, hardly reacts with any substance, has a low friction coefficient, and is very suitable as a lining or coating for the piston, especially for contact with chemically active or corrosive glues.

[0036] The second material barrel 2 has the same structure as the first material barrel 1 .

[0037] When in use, a driving mechanism such as a cylinder can be provided on the push rod 14. When needed, the push rod 14 is pushed, and the A and B glues are dropped from the first barrel 1 and the second barrel 2 through the solenoid valve from the storage chamber 11 into the pre-storage chamber 12. The electronic scale at the bottom of the pre-storage chamber 12 weighs the weight of the glue. At the same time, there are scale lines on the wall of the pre-storage chamber 12, and the scale lines are used when the volume of the glue needs to be measured. If the glue output is less than the demand, the solenoid valve can be opened again to discharge the glue until the required amount is reached.

[0038] A solenoid valve is also provided at the bottom of the pre-storage chamber 12 to control the glue to fall into the mixing barrel 4 through the connecting pipe 3. The motor 41 is turned on to drive the rotating shaft 43 to rotate, so that the entire turntable ring 421 rotates. Because the rotating blades 424 rotate on the supporting ribs 423, the glue is stirred to make the AB glue mixed evenly.

[0039] The rubber hose 5 is connected to the glue dispensing gun 8 through a pump, and the position of the glue dispensing gun 8 is adjusted by the first sliding cylinder 71 and the second sliding cylinder 72 to perform glue dispensing.
