[0017] The utility model discloses a whole structure schematic diagram. Figures 1 to 3 The utility model discloses a whole structure schematic diagram.

[0018] A kind of rubber blocking plate of pre-coated film coating roller, including the middle part of support 1 is connected with coating roller 101, the middle part of support 1 is connected with press roll 102 below coating roller 101, the middle part of support 1 is connected with two-way screw 103, the side wall of coating roller 101 is connected with rubber blocking plate 2, the middle part of rubber blocking plate 2 is connected and is arranged with limited ring groove 203, the middle part of limited ring groove 203 is connected with rotary ring 202, the side wall of rotary ring 202 is provided with embedded ring 2021, embedded ring 2021 side wall is connected with ball 2022, rubber blocking plate 2 further includes displacement block 201, displacement block 201 is arranged at the top of rubber blocking plate 2, two-way screw 103 is screwed through displacement block 201.

[0019] First, the glue is poured on the plastic film, and then the plastic film with glue is passed between the coating roller 101 and the pressing roller 102 to extrude the glue on the plastic film, so that the glue on the plastic film can be uniformly coated on the plastic film with consistent thickness. At the same time, during the coating process, the rotating bidirectional screw 103 is used to control the displacement block 201 on the glue blocking plate 2 to move towards and away from each other, so that the glue blocking plate 2 is close to the two sides of the plastic film, avoiding the accumulation of glue to the two sides during extrusion. Synchronous replacement of different lengths of pressing roller 102 for cooperation.

[0020] Further, the rotating ring 202 is a circular ring connected to the middle part of the displacement block 201, and the inner diameter of the rotating ring 202 cooperates with the coating roller 101. The embedded ring 2021 is a circular ring protruding from the side wall of the rotating ring 202, and the rotating ring 202 is connected to the limited ring groove 203 through the embedded ring 2021 on the side wall. The protruding part of the ball 2022 is connected to the side wall of the embedded ring 2021, and the ball 2022 is in contact with one side of the middle part of the limited ring groove 203. The rotating ring 202 also includes a sealing ring 2023, which is arranged in the middle part of the rotating ring 202.

[0021] At the same time, the glue blocking plate 2 will be displaced by the control of the bidirectional screw 103, so it will not rotate with the coating roller 101. When the coating roller 101 rotates, it will rub the rotating ring 202 in the middle of the glue blocking plate 2 to rotate. The rotating ring 202 is embedded in the limited ring groove 203 through the embedded ring 2021 on the side wall, and is in contact through the ball 2022 to reduce friction, making it easier for the coating roller 101 to rub the rotating ring 202 to rotate together, thereby avoiding the friction of the coating roller 101 on the inner wall of the middle part of the glue blocking plate 2 when rotating, which can cause wear and tear of the inner wall of the middle part of the glue blocking plate 2, resulting in gaps that allow glue to leak.

[0022] Further, the sealing ring 2023 is arranged on the side of the rotating ring 202 in contact with the coating roller 101.

[0023] At the same time, the sealing ring 2023 seals the contact surface between the rotating ring 202 and the coating roller 101, and also increases the friction between the rotating ring 202 and the coating roller 101, so that it can be rotated by the coating roller 101.

[0024] The following is the specific process of the utility model, first pour the glue solution on the plastic film, then let the plastic film with glue solution pour through the coating roller 101 and the pressing roller 102 between, to extrude the glue solution on the plastic film, to let the glue solution on the plastic film can be uniformly thick and consistent to be coated on the plastic film, at the same time before coating, first through the rotating bidirectional screw 103 to control the displacement block 201 on the two glue blocking plates 2 to separate and close the movement, to adapt to the width of the film, so that the glue blocking plate 2 is close to the two sides of the plastic film, avoid the glue solution to accumulate and flow out to both sides when extruding the glue solution, synchronous replacement different length pressing roller 102 to cooperate.

[0025] At the same time, the glue blocking plate 2 will be displaced by the control of the bidirectional screw 103, so it will not rotate with the coating roller 101, when the coating roller 101 rotates, it will rub the rotating ring 202 in the middle of the glue blocking plate 2 to rotate, and the rotating ring 202 is embedded in the limiting ring groove 203 through the embedded ring 2021 of the side wall, and is in contact through the ball 2022, reducing friction, so that the coating roller 101 is more easily rubbed to drive the rotating ring 202 to rotate together, thereby avoiding the friction of the coating roller 101 to the inner wall of the middle of the glue blocking plate 2 when rotating, which makes it easy to cause wear and tear of the inner wall of the middle of the glue blocking plate 2, producing a gap, so that the glue solution will leak from the gap caused by wear and tear.
