[0025] See also Figure 1-Figure 5 The utility model provides the following technical solution: an adhesive production degassing device, comprising an outer shell 1, the upper side of the outer shell 1 is connected to a feed port 2, the lower end of the outer shell 1 is connected to a discharge port 3, a vacuum pump 4 is installed on the upper right side of the outer shell 1, the air inlet end of the vacuum pump 4 is connected to an exhaust pipe 5, and the exhaust end of the vacuum pump 4 is connected to an exhaust pipe 6;

[0026] Furthermore, the exhaust pipe 5 and the exhaust pipe 6 are both in an inverted "L"-shaped structure, and one end of the exhaust pipe 5 extends into the interior of the outer shell 1, so that the vacuum pump 4 can smoothly perform a vacuum operation on the outer shell 1, causing the bubbles to rise and escape;

[0027] A first motor 7 is installed on the upper left side of the outer shell 1. The output end of the first motor 7 is connected to a reciprocating screw 8. The outer side of the reciprocating screw 8 is threadedly connected to a mounting seat 9. The right end of the mounting seat 9 passes through a limit rod 10. The upper end of the limit rod 10 is connected to the outer shell 1.

[0028] Furthermore, the reciprocating screw 8 and the limiting rod 10 are arranged parallel to each other, and the lowest point of the limiting rod 10 is flush with the lowest point of the reciprocating screw 8, so that when the reciprocating screw 8 controls the movement of the mounting seat 9, the movement distance of the mounting seat 9 on the reciprocating screw 8 and the limiting rod 10 is the same;

[0029] Furthermore, the mounting seat 9 is slidably connected to the limiting rod 10. The lower end of the mounting seat 9 is hollowed out. The limiting rod 10 is used to limit the movement of the mounting seat 9 to ensure that it maintains vertical movement. The hollow shape of the mounting seat 9 facilitates the assembly of the rotating rod 12, the sleeve 17 and other structures.

[0030] A second motor 11 is mounted inside the mounting base 9. The output end of the second motor 11 is connected to a rotating rod 12. A lower stirring rod 19 is mounted at the lower end of the rotating rod 12. A sleeve 17 is sleeved on the outer side of the rotating rod 12.

At the same time, the mounting seat 9 slides on the limit rod 10 to ensure the vertical movement of the mounting seat 9, thereby controlling the upper stirring rod 18 and the lower stirring rod 19 to move back and forth up and down, so that the upper stirring rod 18 and the lower stirring rod 19 stir and break up the adhesives of different heights, and the vertical movement of the upper stirring rod 18 and the lower stirring rod 19 can press the bubbles in the adhesive to further eliminate the bubbles in the adhesive. After degassing is completed, the valve on the discharge port 3 can be opened to take out the adhesive.
