[0024] Please refer to Figures 1 to 5, a film material automatic loading mechanism, including a base 1. At the bottom of one side of the base 1, a supporting roller 2 is rotatably connected. In the middle of one side of the base 1, there is a roller seat 4. Inside the roller seat 4, a pressure roller 3 is rotatably connected. At the top of one side of the base 1, there is a cylinder 6. The telescopic rod of the cylinder 6 is connected to a pressing component 7 that presses on the roller seat 4. At the top of the base 1, there is a driving chamber 11. Inside the driving chamber 11, a bidirectional lead screw 13 is rotatably connected. On one side of the driving chamber 11, there is a motor 12 that drives the bidirectional lead screw 13. On both sides of the bidirectional lead screw 13, there are support components 14. At the bottom of the support component 14, there is a support shaft 16 that limits the film roller. By driving the bidirectional lead screw 13 with the motor 12, the bidirectional lead screw 13 can make the two support components 14 move towards each other. Subsequently, the two support shafts 16 can move towards each other and automatically push into both ends of the film roller. When the support shaft 16 supports the film roller, it can limit it and prevent the film roller from falling;

[0025] In this embodiment, preferably, the pressing component 7 includes a horizontal plate 701. The middle of the top of the horizontal plate 701 is fixedly connected to the telescopic rod of the cylinder 6. A plurality of guide columns 702 are slidably connected to the surface of the horizontal plate 701. The bottom ends of the guide columns 702 are fixedly connected to the top of the roller seat 4. A spring 703 is sleeved on the surface of the guide column 702. The spring 703 is located between the horizontal plate 701 and the roller seat 4. In the middle of the guide column 702, a baffle 704 is fixedly provided. The baffle 704 is located at the top of the horizontal plate 701. At the top of one side of the base 1, a support rod 5 is fixedly provided. The cylinder 6 is fixedly connected to the middle of the top of the support rod 5. The guide column 702 is slidably connected to the support rod 5. By lifting the horizontal plate 701 with the cylinder 6, the horizontal plate 701 can lift the roller seat 4 through the baffle 704, increasing the operating space between the supporting roller 2 and the pressure roller 3 and facilitating the laying of the film. By driving the horizontal plate 701 to descend with the cylinder 6, the horizontal plate 701 can transfer the pressure to the roller seat 4 through the spring 703, thus pressing the film tightly, avoiding the slack and wrinkles of the film. When the traction force during unwinding is relatively large, the pressure roller 3 can be lifted to compress the spring 703, which can play a buffering role and the film is not easily deformed and torn;

[0026] In this embodiment, preferably, the support assembly 14 includes a threaded sleeve 1401 and a suspension rod 1402. The threaded sleeve 1401 is threadedly connected to the bidirectional lead screw 13. The top end of the suspension rod 1402 is fixedly connected to the bottom of the threaded sleeve 1401. The bottom end of the suspension rod 1402 is fixedly provided with a support plate 1403. The support shaft 16 is rotatably connected to the middle of the support plate 1403. The top of the threaded sleeve 1401 is fixedly provided with a support block 1404. The inner wall of the top end of the drive chamber 11 is fixedly provided with a support rail 15. The support block 1404 is slidably connected to the support rail 15. The support block 1404 and the support rail 15 can support and guide the threaded sleeve 1401, preventing the bidirectional lead screw 13 from bearing vertical forces. The threaded sleeve 1401 can support the support plate 1403. By driving the bidirectional lead screw 13 with the motor 12, the bidirectional lead screw 13 can convert the rotational motion into the linear motion of the support plate 1403 through the threaded sleeve 1401;

[0027] In this embodiment, preferably, a protective cover 8 is fixedly provided on one side of the top end of the base 1. A groove 9 is formed on one side of the top end of the protective cover 8. The air cylinder 6 is located inside the groove 9. The protective cover 8 can protect the air cylinder 6 and the pressing assembly 7, avoiding human contact, being safe and reliable. On both sides of the bottom end of the drive chamber 11, vertical plates 10 are fixedly provided. The bottom ends of the vertical plates 10 are fixedly connected to the top end of the base 1. The vertical plates 10 can provide support between the base 1 and the drive chamber 11;

[0028] In this embodiment, preferably, a stop disc 17 is fixedly provided on the surface of the support shaft 16. An inclined plug 18 is fixedly provided at one end of the support shaft 16. The inclined plug 18 can guide the support shaft 16, facilitating its insertion into the film drum. The stop disc 17 can limit the two ends of the film drum.

[0029] During use, first, the motor 12 drives the bidirectional lead screw 13 to rotate. The bidirectional lead screw 13 converts the rotational motion into the linear motion of the support plate 1403 through the threaded sleeve 1401. The support block 1404 and the support rail 15 can support and guide the threaded sleeve 1401, preventing the bidirectional lead screw 13 from bearing vertical forces, thereby increasing the distance between the two support shafts 16. Then, the motor 12 drives the bidirectional lead screw 13 in the reverse direction. The support plate 1403 drives the support shafts 16 to move towards each other. The inclined plug 18 can guide the support shafts 16, facilitating their insertion into the film drum. When the support shafts 16 support the film drum, they can limit it, preventing the film drum from falling;

[0030] After the film roller is installed, the pressing assembly 7 is lifted by the air cylinder 6 to increase the operating space between the idler roller 2 and the pressure roller 3, and the film is laid and conducted. Then, the air cylinder 6 drives the pressing assembly 7 to descend, and the horizontal plate 701 can transfer the pressure to the roller seat 4 and the pressure roller 3 through the spring 703, so that the film can be automatically tightened, avoiding the slack and wrinkles of the film. When the traction force during unwinding is large, the film can lift the pressure roller 3 and compress the spring 703, which can play a buffering role, and the film is not easily deformed or torn. After the film is used, the film roller can be removed by driving the bidirectional lead screw 13 by the motor 12 again, and it can be quickly replaced.
