[0019] The technical scheme in the utility model embodiments will be described clearly and completely below in conjunction with the drawings in the utility model embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] like Figure 2 As shown, the degassing assembly used in the light guide plate production line includes a screw body 1 and a degassing hole 2. The screw body 1 has a conveying channel extending along the axial direction, and the degassing hole 2 is disposed on the wall of the conveying channel of the screw body 1 for degassing the polymer liquid during the rotation of the screw body 1.

[0022] The degassing hole 2 is designed to be narrower to reduce leakage of polymer liquid. A first inclined block 3 and a second inclined block 4 are installed at the degassing hole 2. The first inclined block 3 and the second inclined block 4 are arranged opposite to each other. There are multiple degassing holes 2, and each degassing hole 2 is equipped with a first inclined block 3 and a second inclined block 4 to achieve more efficient degassing and reduce leakage.

[0023] The first inclined block 3 includes a first slope 5 and a second slope 6. The first slope 5 is inclined toward the inlet of the degassing hole 2, and the second slope 6 is connected to the first slope 5 and inclined toward the outlet of the degassing hole 2. A first tip 7 is formed between the first slope and the second slope 6.

[0024] The second inclined block 4 includes a third slope 8 and a fourth slope 9. The third slope 8 is inclined toward the inlet of the degassing hole 2. The third slope 8 is opposite to the first slope 5 and the first tip 7. The fourth slope 9 is connected to the third slope 8 and is inclined toward the outlet of the degassing hole 2. A second tip 10 is formed between the third slope and the fourth slope 9.

[0025] The angle of the second tip 10 is greater than that of the first tip 7. The polymer liquid will flow from the first tip 7 to the third slope 8 and finally back to the first tip 7, making a loop. The second tip 10 and the fourth slope 9 are both positioned opposite to the second slope 6. A first liquid flow path exists between the first slope 5, the first tip 7, and the third slope 8.

[0026] A second liquid flow path exists between the second slope 6, the second tip 10, and the fourth slope 9. The polymer liquid first flows through the first liquid flow path and then flows out through the second liquid flow path, so that the gas discharge is not obstructed.

[0027] Working principle: when the screw body 1 rotates, the high polymer liquid first flows along the first slope surface 5 of the first inclined block 3 to the first pointed part 7, then the high polymer liquid flows from the first pointed part 7 to the third slope surface 8, then the high polymer liquid flows along the third slope surface 8 to the second liquid flow path, then the high polymer liquid continues to flow along the second pointed part 10 to the fourth slope surface 9, finally, the high polymer liquid leaks out from between the second slope surface 6 and the fourth slope surface 9, and due to the cooperation of the first inclined block 3 and the second inclined block 4, the high polymer liquid is less hindered in the flow process, and the leakage of the high polymer liquid from the degassing hole 2 is reduced by reducing the aperture of the degassing hole 2.

[0028] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application, and any common change and replacement within the technical scheme range of the present application should be included in the protection range of the present application.
