[0011] 1. The automatic film rolling device for cast film is provided with a film rolling wheel, a pressure rod, a spring, a pressure plate and an upper pressure wheel. When the film is rolled, the motor drives the film rolling wheel to rotate to roll the film. During the film rolling process, the upper pressure wheel will be close to the cast film being rolled, so that the upper pressure wheel and the film rolling wheel maintain a clamped state on the cast film. During the film rolling process, the thickness of the cast film rolled by the film rolling wheel continues to increase, so that the upper pressure wheel squeezes the pressure plate, and the pressure plate drives the pressure rod to squeeze the spring. The reaction force of the spring makes the upper pressure wheel continue to squeeze the cast film, and the cast film will not be damaged due to the increase in the thickness of the rolled film. The problem of easy dislocation due to the low thickness and light weight of the cast film during film rolling is solved, and the overall film rolling effect is guaranteed.

[0012] 2. The automatic film rolling device for cast film is provided with a slide rail, a mounting frame, a roller and a cutting knife. After the film rolling is completed, the mounting frame is pulled or pushed, and the mounting frame slides on the slide rail through the roller, driving the cutting knife to move.

DETAILED DESCRIPTION

[0017] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0018] like Figure 1-3 As shown, the utility model provides a technical solution: an automatic film rolling device for cast film, comprising a base 1, two bottom plates 2 are fixedly installed on the top of the base 1, and bottom angles 26 are fixedly installed at the four corners below the bottom plate 2, respectively, and the bottom angles 26 are aluminum alloy bottom angles. Because the material of the bottom angle 26 is the aluminum alloy bottom angle 26, this material has high strength and long durability, which ensures the service life of the bottom angle 26;

[0019] Three pressure rods 3 are fixedly installed on the top of the bottom plate 2, and springs 4 are connected to the outer sleeves of the pressure rods 3. A pressure plate 5 is fixedly installed on the end of the pressure rod 3 away from the bottom plate 2, and a fixed plate 6 is fixedly installed on one side of the pressure plate 5. Upper pressure shafts 7 are provided on both sides of the fixed plate 6, and the upper pressure shafts 7 penetrate the fixed plate 6. Two upper pressure wheels 8 are provided on the outer wall of the upper pressure shaft 7. Two brackets 9 are fixedly installed on both sides of the base 1, and a hook 19 is fixedly installed on one side of the bracket 9. A film winding shaft 20 is rotatably connected in the hook 19, and a film winding wheel 21 is provided outside the film winding shaft 20. A positioning port 22 is opened on the outer wall of the film winding wheel 21. Because the positioning port 22 is provided, when the device is rolling film, one end of the cast film is placed in the positioning port 22, so that the film can be rolled conveniently when the machine starts to roll the film, so as to avoid affecting the film rolling effect due to the end not being fixed well when rolling the film;

[0020] A working cabin 23 is provided outside the bracket 9, and a motor 24 is fixedly installed on one side of the working cabin 23. One end of the motor 24 passes through one side of the working cabin 23, and one end of the motor 24 is connected to one end of the film rolling shaft 20. Because the motor 24 is provided, the motor 24 drives the film rolling shaft 20 to rotate. When the film is rolled, there is no need to manually rotate the film rolling wheel 21, which improves the work efficiency. A feed inlet 25 is provided on one side of the working cabin 23, and the position of the feed inlet 25 corresponds to the position of the lower pressure wheel 17. Two mounting plates 10 are fixedly installed on the inner walls of the two brackets 9 respectively;

[0021] The inner walls of the mounting plates 10 are respectively provided with rotation grooves 15, and the inner walls of the rotation grooves 15 are rotatably connected with a lower pressure shaft 16, and a lower pressure wheel 17 is arranged outside the lower pressure shaft 16, and a cross plate 18 is arranged below the lower pressure wheel 17, and the cross plate 18 is fixedly mounted between the two mounting plates 10. Through the cooperation between the lower pressure wheel 17 and the cross plate 18, when the film is rolled, the cast film passes through the cross plate 18, and the rolling of the lower pressure wheel 17 ensures the flatness of the cast film before the film is rolled, thereby ensuring the film rolling effect. The inner walls of the two mounting plates 10 are fixedly connected with slide rails 11, and the upper part of the slide rails 11 is slidably connected with a mounting frame 12, and the inner wall of the mounting frame 12 is slidably connected with a roller 13, and the bottom end of the mounting frame 12 is fixedly connected with a cutting knife 14. Because the cutting knife 14 is provided, the cutting knife 14 is pushed or pulled after the film is rolled to separate the remaining cast film from the rolled cast film, and there is no need for manual cutting with the help of other tools, thereby improving work efficiency.

[0022] The working principle of the utility model is as follows: when the device is used, the cast film is fed in from the feed port 25, passes through between the lower pressure wheel 17 and the cross plate 18, one end of the cast film is placed in the positioning port 22, the motor 24 is started, and the motor 24 drives the film rolling wheel 21 to roll the film. When rolling the film, the upper pressure wheel 8 and the film rolling wheel 21 cooperate with each other to keep the cast film in a clamped state. When the film rolling wheel 21 reaches a certain thickness, the mounting frame 12 is pulled or pushed, so that the mounting frame 12 drives the cutting knife 14 to move on the slide rail 11 through the roller 13 to separate the cast film to be rolled and the cast film that has been rolled, thereby completing the film rolling of the cast film.
