Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Please see Figure 1-3 This utility model provides a technical solution: a woven bag coating mechanism, comprising:

[0023] A fixed base plate 1 is provided, and a main fixing frame 2 is fixedly provided on the top of the outer wall of the fixed base plate 1;

[0024] The membrane structure is located within the main fixing frame 2;

[0025] The coating structure includes a sliding frame 3, two main fixing rods 4, a secondary fixing rod 5, two pressing rollers 6, a heating roller 7, a main pulley 8, a secondary pulley 9, and a control motor 10. The outer wall of the sliding frame 3 is slidably embedded in the sliding frame 3. The outer walls of the two main fixing rods 4 and the secondary fixing rods 5 are fixedly embedded in the sliding frame 3. The inner walls of the two pressing rollers 6 are respectively rotatably sleeved on the two main fixing rods 4. The inner wall of the heating roller 7 is rotatably sleeved on the secondary fixing rod 5. The bottom of the outer wall of the control motor 10 is installed on the sliding frame 3. The output end of the control motor 10 is fixedly embedded in the main pulley 8. One side of the outer wall of the secondary pulley 9 is fixed on the heating roller 7. A transmission belt 11 is wound between the main pulley 8 and the secondary pulley 9.

[0026] The conveying structure is located at the bottom of the fixed base plate 1.

[0027] In this implementation scheme: the main fixed frame 2 can be fixed by the fixed base plate 1, and the sliding frame 3 can slide up and down stably by the main fixed frame 2. When the control motor 10 is energized, the output end drives the main pulley 8 to rotate. The main pulley 8 is connected to the auxiliary pulley 9 by the transmission belt 11, thereby controlling the rotation of the auxiliary pulley 9. The auxiliary pulley 9 drives the heating roller 7 to rotate on the auxiliary fixed rod 5. When the heating roller 7 is energized, heat is generated on its surface, which can perform heat melting treatment on the film surface. The two main fixed rods 4 can make the two pressing rollers 6 rotate stably. The two pressing rollers 6 can make the film stick to the surface of the woven bag, thus facilitating the heat melting treatment.

[0028] Specifically, a threaded rod 12 is rotatably embedded in the top of the outer wall of the sliding frame 3. The outer wall of the threaded rod 12 is threadedly embedded in the main fixed frame 2, and a rotating disk 13 is fixedly mounted on the top of the threaded rod 12.

[0029] In this embodiment: the rotating disk 13 facilitates the control of the threaded rod 12 to rotate within the main fixed frame 2, and the threaded rod 12 is moved up and down by the thread, thereby driving the sliding frame 3 to move.

[0030] Specifically, the conveying structure includes a secondary fixed frame 14, two rotating rods 15, two conveying pipes 16, a support plate 17, and a conveyor belt 18. The top of the outer wall of the secondary fixed frame 14 is fixedly mounted on the fixed base plate 1, and the outer walls of the two rotating rods 15 are rotatably embedded in the secondary fixed frame 14.

[0031] In this embodiment, two rotating rods 15 can drive two conveying pipes 16 to rotate stably.

[0032] Specifically, the inner walls of the two conveying pipes 16 are respectively fixedly sleeved on the two rotating rods 15, the inner wall of the conveyor belt 18 is wound around the two conveying pipes 16, and the outer wall of the support plate 17 is fixedly embedded in the fixed base plate 1.

[0033] In this embodiment: the conveyor belt 18 is moved by two conveying pipes 16, and the support plate 17 can be supported inside the conveyor belt 18 so that the top of the conveyor belt 18 is supported. With the pressing of the heating roller 7, the film is thermally melted onto the woven bag.

[0034] Specifically, a conveyor motor 19 is installed on one side of the outer wall of the secondary fixed frame 14, and the output end of the conveyor motor 19 is fixed on one of the rotating rods 15.

[0035] In this embodiment, the output end of the conveyor motor 19, when energized, drives one of the rotating rods 15 to rotate, providing power output.

[0036] Specifically, two support frames 20 are fixedly installed on the outer wall of the fixed base plate 1 away from the main fixed frame 2, and a membrane frame 21 is rotatably installed at the top of the two support frames 20.

[0037] In this embodiment: the film frame 21 can be rotated stably by two support frames 20, and the film frame 21 is wrapped with film.

[0038] In use, the fixed base plate 1 can fix the main fixed frame 2, which in turn allows the sliding frame 3 to slide stably up and down. When the control motor 10 is powered on, its output end drives the main pulley 8 to rotate. The main pulley 8 is connected to the auxiliary pulley 9 via the transmission belt 11, thereby controlling the rotation of the auxiliary pulley 9. The auxiliary pulley 9 drives the heating roller 7 to rotate on the auxiliary fixed rod 5. When powered on, the heating roller 7 generates heat on its surface, which can perform heat-melting treatment on the film surface. The two main fixed rods 4 can stably rotate the two pressing rollers 6, which can adhere the film to the surface of the woven bag, thus facilitating heat-melting treatment. The rotating disk 13 can conveniently control the threaded rod 12 to rotate within the main fixed frame 2, using the thread to make the threaded rod 12 rotate. The rod 12 moves up and down, thereby driving the sliding frame 3 to move. The two rotating rods 15 can drive the two conveying pipes 16 to rotate stably. The two conveying pipes 16 drive the conveyor belt 18 to move. The support plate 17 can support the conveyor belt 18, so that the top of the conveyor belt 18 is supported. With the pressing of the heating roller 7, the film is heat-melted onto the woven bag. The output end of the conveyor motor 19 drives one of the rotating rods 15 to rotate under the clean power supply, providing power output. The two support frames 20 can make the film frame 21 rotate stably. The film frame 21 is wrapped with film, which can help the film adhere to the surface of the woven bag. With heat treatment and in conjunction with the conveying structure, the woven bag and the film are heat-melted together while moving the woven bag, thereby improving the efficiency of film coating.
