[0032] The side of the hot air blower 10 close to the connecting plate 2 3 passes through the connecting plate 2 3 and is fixedly connected to the hot air pipe 11, and the hot air pipe 11 passes through the connecting plate 8 and is fixedly connected. Four hot air pipes 11 are passed through and fixedly connected to the four sides of the outer wall of the annular connecting box 6. Two connecting pipes 12 are passed through and fixedly connected on both sides of the outer wall of a connecting pipe 1 7, and the connecting pipe 2 12 passes through the hot air pipe 11 and is fixedly connected. The ends of the two connecting pipes 2 12 away from the connecting pipe 1 7 pass through and are fixedly connected to the connecting pipe 3 14. The edge parts of both sides of the hot air pipe 11 are fixedly connected to the connecting blocks 13. The two connecting blocks 13 are rotatably connected to the rotating rod 2 17 on the side away from the hot air pipe 11. The outer wall of the rotating rod 2 17 is provided with a heating roller 18;

[0033] The inner cavity of the heating roller 18 is rotatably connected with rotating disks 2 19 on both sides, and the middle parts of the two rotating disks 2 19 pass through the rotating rod 2 17 and are fixedly connected. The side of the connecting tube 3 14 away from the connecting block 13 is fixedly connected with a U-shaped connecting tube 15.

[0034] The above scheme is adopted: when the greenhouse film passes through the connecting plate 1 2 and the connecting plate 2 3, the motor 4 is first turned on to make the rotating rod 1 5 drive the annular connecting box 6 to rotate counterclockwise, and the greenhouse film is squeezed and smoothed through the hot air pipe 11 and the heating roller 18. At the same time, the annular connecting box 6 is rotated to turn on the hot air blower 10 to transport the hot air to the connecting disk 8, and then the hot air will enter the connecting pipe 1 7 through the connecting disk 8, and the hot air will be transmitted to the connecting pipe 2 12, the connecting pipe 3 14 and the U-shaped connecting pipe 15 through the connecting pipe 1 7. Finally, the hot air is transported to the heating roller 18 through the ventilation groove 16 to heat the heating roller 18, so that the greenhouse film can be smoothed during the production heat shaping treatment.

[0035] When the annular connecting box 6 rotates counterclockwise to drive the connecting pipe 7 to rotate counterclockwise, there are four connecting pipes 7. For example, when the top connecting pipe 7 rotates to ninety degrees, the gravity plate 24 drives the arc plate 23 to rotate under the influence of gravity to open the arc groove 22. After the arc groove 22 is opened, the hot air in the connecting pipe 7 will be transported to the corresponding hot air groove 20, and then the hot air will be discharged through the air outlet groove 21 to evenly heat the greenhouse film.

[0036] like Figures 1 to 11 As shown, a connecting pipe 7 is provided with an arc-shaped groove 22 on one side, an arc-shaped plate 23 is rotatably connected to one side of the arc-shaped groove 22, and a gravity plate 24 is fixedly connected to one side of the outer wall of the arc-shaped plate 23;

[0037] A hot air slot 20 is formed on one side of the hot air pipe 11 , and the hot air slot 20 cooperates with the arc slot 22 . Both sides of the hot air slot 20 penetrate the hot air pipe 11 and are provided with air outlet slots 21 .

[0038] The above scheme is adopted: when the top connecting pipe 1 7 rotates 270 degrees, the gravity plate 24 drives the arc plate 23 to reset and enter the arc groove 22 for sealing. When the arc groove 22 is closed, the heat will pass through the connecting pipe 1 7 and the hot air will be transmitted to the connecting pipe 2 12, the connecting pipe 3 14 and the U-shaped connecting pipe 15. Finally, the hot air will be transported to the heating roller 18 through the ventilation groove 16 to heat the heating roller 18.

[0039] like Figures 1 to 11 As shown, a dust removal box 25 is installed on one side of the top of the workbench 1, and two wool rollers 26 are installed in the inner cavity of the dust removal box 25;

[0040] The top of the workbench 1 is fixedly connected to both sides of the dust removal box 25 with a second fixing frame 33, and a guide roller 34 is rotatably connected between the two fixing frames 33;

[0041] The top of the workbench 1 is located between the second fixing frame 33 and the connecting plates 1 2 and 2 3. Both sides are fixedly connected to the first fixing frame 27. The sides of the two fixing frames 27 that are relatively close to each other are penetrated and have a sliding groove 28. The sides of the two fixing frames 27 that are relatively close to each other and away from the sliding groove 28 are rotatably connected to the second pressing roller 32.

[0042] A spring 29 is installed at the top of the inner cavity of the two sliding grooves 28. A slider 30 is fixedly connected to the side of the two springs 29 away from the sliding groove 28. A pressing roller 31 is rotatably connected between the two sliders 30.

[0043] A support plate 35 is fixedly connected to one side of the workbench 1 close to the second connecting plate 3 , and an end of the support plate 35 away from the workbench 1 is fixedly connected to the hot air blower 10 .

[0044] Adopt the above scheme: pass the greenhouse film through the dust removal box 25 and the wool roller 26 to clean the dust and impurities on the surface of the greenhouse film;

[0045] When the greenhouse film passes between the pressing roller 1 31 and the pressing roller 2 32, the elastic force of the spring 29 causes the slider 30 to drive the pressing roller 1 31 downward to squeeze and flatten the greenhouse film.

[0046] The support of the hot air blower 10 by the support plate 35 makes the hot air blower 10 more stable during operation.

[0047] The working principle and use process of the present invention:

[0048] During operation, the greenhouse film is first passed through the dust removal box 25 and the wool roller 26 to clean the dust and impurities on the surface of the greenhouse film. Then the greenhouse film passes through the bottom between the connecting plate 1 2 and the connecting plate 2 3, and then passes through the pressure roller 1 31 and the pressure roller 2 32, and finally is placed on the guide roller 34 to reel the greenhouse film. When the greenhouse film passes between the connecting plate 1 2 and the connecting plate 2 3, the motor 4 is first turned on to make the rotating rod 1 5 drive the annular connecting box 6 to rotate counterclockwise, and the greenhouse film is squeezed and smoothed through the hot air pipe 11 and the heating roller 18. At the same time, when the annular connecting box 6 rotates, the hot air blower 10 is turned on to transport the hot air to the connecting disk 8, and then the hot air will pass through the connecting disk 8 into the connecting pipe 1 7, and through the connecting pipe 1 7, the hot air is transmitted to the connecting pipe 2 12, the connecting pipe 3 14 and the U-shaped connecting pipe 15. Finally, the hot air is transported to the heating roller 18 through the ventilation groove 16 to heat the heating roller 18, so that the greenhouse film can be smoothed during the production heat shaping process;

[0049] During operation, the greenhouse film is first passed through the dust removal box 25 and the wool roller 26 to clean the dust and impurities on the surface of the greenhouse film. Then the greenhouse film passes through the bottom between the connecting plate 1 2 and the connecting plate 2 3, and then passes between the pressing roller 1 31 and the pressing roller 2 32. The elastic force of the spring 29 drives the slider 30 to drive the pressing roller 1 31 to press down and squeeze and flatten the greenhouse film. Finally, it is placed on the guide roller 34 to reel the greenhouse film. When the greenhouse film passes between the connecting plate 1 2 and the connecting plate 2 3, the motor 4 is first turned on to make the rotating rod 1 5 drive the ring The annular connecting box 6 rotates counterclockwise, and the hot air pipe 11 and the heating roller 18 are used to squeeze and smooth the greenhouse film. At the same time, the annular connecting box 6 rotates to turn on the hot air blower 10 to transport the hot air to the connecting plate 8. Then the hot air will pass through the connecting plate 8 and enter the connecting pipe 1 7. Through the connecting pipe 1 7, the hot air is transmitted to the connecting pipe 2 12, the connecting pipe 3 14 and the U-shaped connecting pipe 15. Finally, the hot air is transported to the heating roller 18 through the ventilation groove 16 to heat the heating roller 18, so that the greenhouse film can be smoothed during the production heat shaping process;

[0050] At the same time, when the annular connecting box 6 rotates counterclockwise to drive the connecting pipe 7 to rotate counterclockwise, there are four connecting pipes 7. For example, when the top connecting pipe 7 rotates to ninety degrees, the gravity plate 24 drives the arc plate 23 to rotate through the influence of gravity to open the arc groove 22. After the arc groove 22 is opened, the hot air in the connecting pipe 7 will be transported to the corresponding hot air groove 20, and then the hot air will be discharged through the air outlet groove 21 to evenly heat the greenhouse film. When the top connecting pipe 7 rotates two hundred and seventy degrees, the gravity plate 24 drives the arc plate 23 to reset and enter the arc groove 22 for sealing. When the arc groove 22 is closed, the heat will pass through the connecting pipe 7 and transmit the hot air to the connecting pipe 2 12, the connecting pipe 3 14 and the U-shaped connecting pipe 15, and finally through the ventilation groove 16 to transport the hot air to the heating roller 18 to heat the heating roller 18.
