[0010] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following, in combination with the drawings and preferred embodiments, details the specific implementation manners, structures, features, and their effects of the present utility model as follows.

[0011] Embodiment 1:

[0012] As Figure 1 、 Figure 2As shown in the figure, the utility model discloses an adhesive stirring device for chopped glass fiber mat, which comprises a box body 1. A rotating shaft 2 is arranged inside the box body 1. The two ends of the rotating shaft 2 are rotatably connected with the side walls of the box body 1, and one end of the rotating shaft 2 extends outside the box body 1. A power mechanism is arranged on the box body 1, and the power mechanism is in transmission connection with the rotating shaft 2 outside the box body 1. An air flow channel 5 extends inwards at the end of the rotating shaft 2 outside the box body 1. A rotary joint 15 is arranged at the end of the rotating shaft 2 outside the box body 1. A blower 13 is arranged on the box body 1. The air outlet pipe 14 of the blower 13 is connected with the rotary joint 15 and communicated with the air flow channel 5 inside the rotating shaft 2. The air inlet pipe 16 of the blower 13 extends to the upper end inside the box body 1. A plurality of stirring rods 3 are arranged on the rotating shaft 2 inside the box body 1 at intervals along the axial direction. Two stirring rods 3 are arranged at the same axial position of the rotating shaft 2, and the two stirring rods 3 at the same axial position are located at both ends of the same diameter. An air outlet 7 is arranged at the outer end of each stirring rod 3. An air outlet channel 6 is arranged inside the stirring rod 3. The diameter of the air outlet 7 is larger than that of the air outlet channel 6. The air outlet 7 and the air outlet channel 6 are connected through a conical structure. A steel ball 8 is arranged in each air outlet 7. The diameter of the steel ball 8 is larger than that of the air outlet channel 6 and smaller than that of the air outlet 7. A connecting line 19 is arranged in the air outlet channels 6 of the two stirring rods 3 at the same radial position of the rotating shaft 2. The two ends of the connecting line 19 are respectively connected with the corresponding steel balls 8 on the same side. The length of the connecting line 19 is larger than the distance between the outermost ends of the air outlet channels 6 of the corresponding stirring rods 3, and the length of the connecting line 19 is smaller than the distance between the connection point of the air outlet 7 and the air outlet channel 6 of one stirring rod 3 and the outermost end of the other stirring rod 3. A feed pipe 9 is arranged at the top of the box body 1, and a feed valve 10 is arranged on the feed pipe 9. A discharge pipe 11 is arranged at the bottom of the box body 1, and a discharge valve 12 is arranged on the discharge pipe 11.

[0013] Wherein, the power mechanism can be the motor 4. The rotating shaft 2 and the motor 4 can be integrated. The rotating shaft 2 penetrates through the motor 4, and the motor 4 is fixed on the box body 1 to drive the rotating shaft 2 to rotate. During the rotation of the rotating shaft 2, the stirring rod 3 on the rotating shaft 2 stirs the adhesive. At the same time, a rotating joint 15 is arranged at the end of the rotating shaft 2 outside the box body 1. The air outlet pipe 14 of the blower 13 is connected to the rotating shaft 2 through the rotating joint 15. Therefore, when the rotating shaft 2 rotates, the air outlet pipe 14 of the blower 13 remains stationary. Meanwhile, the air blown out by the blower 13 enters the internal air flow channel 5 of the rotating shaft 2 through the air outlet pipe 14. Then the air is conveyed to the air outlet 7 through the air outlet channel 6 and enters the adhesive. Since the stirring rod 3 is in a rotating state, the position of the air outlet 7 of the stirring rod 3 is constantly changing, so the position where the air is ejected is also constantly changing, enabling the air to enter the adhesive from different positions and making the stirring of the adhesive more uniform. Since the amount of the adhesive during the stirring process may not necessarily fill the entire box body 1, in order to allow the air to be ejected only from the end of the stirring rod 3 that enters the adhesive, steel balls are arranged at the air outlets 7, and there is a connecting line 19 between the two steel balls. The length of the connecting line 19 is controlled so that in any state, the steel balls will not move outside the air outlet 7. During the rotation of the stirring rod 3, since the air pressures in the air flow channel 5 and the air outlet channel 6 are basically the same, under the gravity of the steel balls, there is a gap between the lower steel ball and the air outlet channel 6, while the upper steel ball is in contact with the air outlet channel 6, so as to promote the air to be output from the air outlet 7 of the lower stirring rod 3 and ensure that the air is always conveyed into the adhesive. Of course, when the amount of the adhesive in the box body 1 is small, when the stirring rod 3 rotates to a horizontal or nearly horizontal state, both stirring rods 3 are located above the adhesive, and at this time, the air cannot enter the adhesive. Once the lower stirring rod 3 contacts the adhesive, the air can enter the adhesive interior.

[0014] Two stirring rods 3 are arranged at the same axial position of the stirring shaft, and the two stirring rods 3 are located in the same radial direction. Therefore, the two air outlet channels 6 are in the same straight line direction and communicate with each other. The connecting line 19 between the two steel balls can remain straight, making the overall movement between the two steel balls more stable and smooth.

[0015] The air outlet 7 and the air outlet channel 6 are connected by a conical structure for transition. When the steel ball 8 is located at the connection between the air outlet 7 and the air outlet channel 6, the edge of the steel ball 8 fits with the edge of the conical structure, and the sealing effect is good.

[0016] The middle part inside the box body 1 is a cylindrical hollow structure, and both ends are conical frustum hollow structures. The three are butted. There is a gap between the end of the stirring rod 3 and the inner wall of the box body 1. The discharge pipe 11 is arranged at the bottom within the range of the cylindrical hollow structure in the middle of the box body 1. With this design of the box body 1, during the internal stirring process, the adhesives on both sides can flow towards the middle part to increase the axial fluidity. Additionally, when discharging, the adhesives on both sides can flow to the middle part, so as to be discharged more thoroughly from the discharge pipe 11.

[0017] An upwardly concave heating cavity 17 is provided at the upper end of the cylindrical hollow structure in the middle of the box body 1. A heating pipe 18 is arranged in the heating cavity 17. The intake pipe 16 of the blower 13 extends into the heating cavity 17. By using the heating cavity 17 at the top and the heating pipe 18 in the heating cavity 17 to heat the air inside the box body 1, and circulating the hot air into the adhesive, the adhesive is ultimately heated, and the heating is uniform and stable.
