[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figure 1 , Figure 2 , Figure 3 As shown, an easy-to-load film applicator unwinding tray includes a mounting frame 1, a transmission frame 2 is provided on one side of the top of the mounting frame 1, and a transmission roller 3 is provided on the top of the transmission frame 2.

The end of the rotating rod 7 near the drive component 5 is mounted on the top middle of the mounting frame 1 via a bearing. The mounting plate 6 is mounted on the outer wall of the end of the rotating rod 7 near the mounting frame 1, and the side of the mounting plate 6 contacts the mounting frame 1. Two protrusions 8 are fixedly connected to the outer wall of the rotating rod 7, symmetrically distributed on both sides of the outer wall. Threaded grooves 9 are provided on the outer wall of the end of the rotating rod 7 away from the drive component 5. The unwinding tray 10 is sleeved on the outside of the rotating rod 7. Furthermore, the unwinding tray 10 has an insertion groove 11 in the middle, the inner wall of the insertion groove 11 is in contact with the outer wall of the rotating rod 7, and there are two grooves 12 on the inner wall of the insertion groove 11, which are symmetrically distributed on the top and bottom inner walls of the insertion groove 11. The grooves 12 are fitted on the outside of the protrusion 8. A threaded limiting plate 13 is installed on the side of the unwinding tray 10, and the threaded limiting plate 13 is connected to the rotating rod 7 through the threaded groove 9. It is engaged with the inside of the insertion groove 11 by the protrusion 8, thereby realizing the limiting connection between the rotating rod 7 and the unwinding tray 10. The threaded limiting plate 13 is connected to the end of the rotating rod 7 away from the driving member 5 through the insertion groove 11, thereby realizing the further limiting of the unwinding tray 10 and preventing the unwinding tray 10 from falling off the rotating rod 7 during use, which would affect the unwinding effect.

[0025] Please see Figure 1 , Figure 2 , Figure 4 As shown, the limiting component 14 includes a mounting block 15. An elastic mounting bracket 16 and a limiting rod 17 are provided on the side of the mounting block 15. A limiting slide rod 19 and a connecting spring 20 are provided in the middle of the elastic mounting bracket 16. An arc-shaped limiting plate 21 is provided at one end of the limiting slide rod 19. A rotating rod 18 is rotatably connected to the middle of the mounting block 15. The end of the rotating rod 18 away from the mounting block 15 is connected to the middle of the side wall of the mounting bracket 1. An elastic mounting bracket 16 is fixedly connected to one side of the mounting block 15. The elastic mounting bracket 16 is L-shaped. The end of the elastic mounting bracket 16 away from the mounting block 15 is fixedly connected to the limiting rod 17. The limiting rod 17 is rotatably connected to the middle of the threaded limiting disc 13.

[0026] The flexible mounting frame 16 is arranged adjacent to the unwinding tray 10. A limiting slide rod 19 is slidably connected to the middle of the side of the flexible mounting frame 16 closest to the unwinding tray 10. An arc-shaped limiting plate 21 is bolted to one end of the limiting slide rod 19, and the arc-shaped limiting plate 21 contacts the outer wall of the unwinding tray 10. There are three limiting slide rods 19, evenly distributed in the middle of the flexible mounting frame 16. A pull plate 22 is bolted to the end of the limiting slide rod 19 furthest from the arc-shaped limiting plate 21. The outer wall of the limiting slide rod 19... A connecting spring 20 is provided on the upper sleeve, and the two ends of the connecting spring 20 are respectively fixedly connected to the side of the pulling plate 22 and the side of the elastic mounting bracket 16. The elastic mounting bracket 16 drives the limiting rod 17 to engage inside the threaded limiting plate 13, thereby limiting the unwinding plate 10. At the same time, the arc-shaped limiting plate 21 is engaged on the outer wall of the unwinding plate 10, thereby limiting the connection of the material roll on the outer wall of the unwinding plate 10 and preventing the material roll from becoming loose during unwinding, which would affect the stability of the device.

[0027] It should be noted that this utility model is an unwinding tray for a film applicator that facilitates material loading. During use, the elastic mounting bracket 16 and mounting block 15 are rotated to displace the arc-shaped limiting plate 21 from the rotating rod 7. Then, the insertion groove 11 in the middle of the unwinding tray 10 is aligned with the rotating rod 7. The unwinding tray 10 is pushed so that it fits onto the outer wall of the rotating rod 7. Simultaneously, the groove 12 on the inner wall of the insertion groove 11 aligns with the protrusion 8 on the outer wall of the rotating rod 7, causing the protrusion 8 to engage inside the groove 12. This achieves the first limiting connection between the unwinding tray 10 and the rotating rod 7. Then, the threaded limiting plate 13 is connected to the end of the rotating rod 7 away from the driving component 5 through the insertion groove 11, thereby achieving further limiting of the unwinding tray 10. Then rotate the elastic mounting bracket 16 so that the end of the elastic mounting bracket 16 away from the mounting block 15 is engaged with the side of the unwinding tray 10 away from the mounting bracket 1. The limiting rod 17 at one end of the elastic mounting bracket 16 is engaged with the middle of the threaded limiting plate 13. The limiting rod 17 is rotatably connected to the mounting block 15. Pull the pulling plate 22 so that the pulling plate 22 drives the limiting slide rod 19 and the connecting spring 20 to retract. Adjust the position of the arc-shaped limiting plate 21 so that the arc-shaped limiting plate 21 is aligned with the outer surface of the unwinding tray 10. Release the pulling plate 22 so that the connecting spring 20 drives the limiting slide rod 19 and the arc-shaped limiting plate 21 to spring back, so that the arc-shaped limiting plate 21 contacts the material roll on the outer wall of the unwinding tray 10. A bottom paper take-up machine is provided below the unwinding assembly 4.
