[0024] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0025] Example

[0026] Please refer to Figure 1-4 As shown, the utility model provides a technical solution: an automatic film cutting machine;

[0027] The inner end of the workbench 1 is fixedly installed with a mounting plate 4, and the inner end of the mounting plate 4 is rotatably installed with a roll film 5. The right end of the workbench 1 is provided with a material discharge chute 6, and a material collection box 7 is provided at the lower side of the material discharge chute 6. A universal wheel 8 is fixedly installed at the lower end of the material collection box 7. The upper end of the workbench 1 is fixedly installed with a bracket 12, and the upper end of the cylinder 20 is fixedly installed with the bracket 12. The upper end of the workbench 1 is fixedly installed with a base 18, and the inner end of the base 18 is provided with a knife groove 19, which is convenient for collecting and carrying the cut film, improving work efficiency, saving time and labor;

[0028] A cutter 9 is fixedly installed at the lower end of the tool holder 2, a metal spring 10 is fixedly installed at the inner end of the tool holder 2, and a pressure strip 11 is fixedly installed at the lower end of the metal spring 10, which is convenient for flattening and limiting the cutting position, avoiding wrinkles and deviations, and improving the straightness and smoothness of the incision. A cylinder 20 is fixedly installed at the upper end of the tool holder 2, and the upper end of the pressure strip 11 is clamped on the inner side of the tool holder 2. The lower end of the pressure strip 11 is lower than the lower end of the cutter 9, which is convenient for replacing the cutter 9, saving costs and improving efficiency.

[0029] The front and rear ends of the electric conveying roller 3 are rotatably mounted with side plates 13, the inner end of the side plates 13 is provided with an adjustment slot 14, the inner end of the adjustment slot 14 is clamped with a mounting frame 15, the inner end of the mounting frame 15 is rotatably mounted with a round roller 17, and the inner end of the adjustment slot 14 is rotatably mounted with a threaded rod 16. The outer end of the threaded rod 16 is threadedly connected to the inner end of the side plate 13. The round roller 17 is arranged parallel to the upper side of the electric conveying roller 3, which is convenient for adjusting the distance between the electric conveying roller 3 and the round roller 17, and is suitable for rolls of different thickness specifications.

[0030] Specific working principle:

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when the automatic film cutting machine is used, the coiled film 5 is installed on the inner side of the mounting plate 4, the coiled film 5 is unrolled, passed between the electric conveying roller 3 and the round roller 17, and then the threaded rod 16 is rotated to adjust the height of the mounting frame 15. When the threaded rod 16 rotates, it drives the mounting frame 15 to move downward on the inner side of the adjustment groove 14, so that the lower end of the round roller 17 is in contact with the upper surface of the film to help loading. Then the electric conveying roller 3 and the round roller 17 rotate to transport the film to the lower side of the bracket 12 on the left side of the workbench 1. When the rightmost end of the film moves out of the bracket 12 and extends to the required length, the cylinder 20 drives the knife holder 2 to move downward. When the knife holder 2 moves downward, the pressure strip 11 is larger than the cutting knife 9. First, it contacts the film, the pressure strip 11 presses the film, the knife holder 2 continues to move downward, the metal spring 10 contracts, the cutter 9 cuts the film, and the cutter 9 falls to the knife groove 19 at the inner end of the base 18 to complete a cut. The cut film slides to the inner side of the discharge chute 6, and then falls into the inside of the collection box 7 for collection. When the collection box 7 needs to be moved, it can be directly retreated. When the sharpness of the cutter 9 decreases and needs to be replaced, the cutter 9 can be directly replaced without removing the knife holder 2. The universal wheel 8 increases the convenience of movement. The above completes a series of operations of the automatic film cutting machine. The content not described in detail in this description belongs to the existing technology known to professional and technical personnel in this field.

[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
