Technical Field

[0001] This utility model relates to the field of cutting device technology, specifically a cutting device for the production of biodegradable and environmentally friendly PE film. Background Technology

[0002] Utility model patent CN220784031U discloses a PE film cutting machine, including a housing. Multiple support feet are arrayed at the bottom of the housing. A connecting block is fixedly connected to the outer wall of the housing, and a driving assembly is located on the top of the connecting block. A fixed frame is fixedly connected to the top of the housing, and a cutting assembly is located inside the fixed frame. This utility model uses the rotation of a feeding roller and a guiding roller to move the PE film. Simultaneously, a push rod connected to a cylinder drives a cutting blade fixedly connected to a cutting blade housing to move rapidly downwards, cutting the PE film. At the same time, the downward movement of the cutting blade housing causes a fixed plate fixed to the cutting blade housing to move synchronously, and the fixed plate drives a fixed column to move. Finally, the fixed column causes a movable plate to contact the PE film placed on the connecting plate, fixing the PE film. Elastic plastic columns on both sides of the connecting plate provide extension to the connecting plate, allowing for better simultaneous cutting and fixing of the PE film.

[0003] However, when using this device, the cutting of PE film is not efficient and stable enough, and the device is not convenient for conveying PE films of different widths. Utility Model Content

[0004] The purpose of this invention is to provide a cutting device for the production of biodegradable and environmentally friendly PE film, which solves the problems of insufficient efficiency and stability in cutting PE film, and the inconvenience of the device in transporting PE films of different widths.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for producing biodegradable and environmentally friendly PE film, comprising a frame, a support roller rotatably connected inside the frame, a support belt provided on the outside of the support roller, a bracket fixedly connected to the upper end of the frame, a cylinder fixedly installed in the middle of the upper end of the bracket, the cylinder rod of the cylinder passing through the bracket and slidably connected to the bracket, a hanger fixedly connected to the lower end of the cylinder rod, a hanging plate fixedly connected to the lower end of the hanger, and a conveying mechanism provided on the hanging plate.

[0006] Preferably, a cutter is fixedly connected to the lower center of the hanging plate, and a cutting groove is provided inside the frame. The cutter cuts the PE film.

[0007] Preferably, the conveying mechanism includes a slide rail, with the slide rail slidably connected inside the suspended plate, and a guide rod slidably connected inside the slide rail. The guide rod is fixedly connected to the suspended plate, and a sliding plate is slidably connected to the upper end of the suspended plate. The sliding plate is slidably connected to the guide rod, and a double-ended screw is threaded inside the sliding plate. A pressure ring is slidably connected to the outer side of the guide rod, and the pressure ring contacts the slide rail. A compression spring is provided on the outer side of the guide rod. A mounting bracket is fixedly connected to the lower end of the slide rail, and a hanging rod is fixedly connected to the upper end of the mounting bracket. The hanging rod is slidably connected to the suspended plate, and a spring is provided on the outer side of the hanging rod. The suspended plate is moved by a cylinder, which compresses the spring. The spring elastically compresses the mounting bracket downwards, causing the conveyor belt to press the PE film onto the support belt for conveying. This prevents the conveyor belt and PE film from separating during the movement of the cutter driven by the suspended plate, thus making the cutting and conveying of the PE film more efficient and stable.

[0008] Preferably, a limiting block is fixedly connected to the upper end of the hanging plate, and the limiting block is slidably connected to the bidirectional screw. The limiting block limits the movement of the bidirectional screw.

[0009] Preferably, one end of the compression spring is fixedly connected to the pressure ring, and the other end of the compression spring is fixedly connected to the slide plate. By setting the compression spring, the pressure ring is elastically compressed.

[0010] Preferably, a conveyor belt is provided at the lower end of the mounting frame, and the conveyor belt is in contact with the support belt. The PE film is conveyed by the conveyor belt.

[0011] Preferably, one end of the spring contacts the hanging plate, and the other end of the spring is fixedly connected to the mounting bracket. By setting the spring, the mounting bracket is elastically pressed down.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses a cylinder to drive the hanging plate to move, which can compress the spring. The spring elastically compresses the mounting frame downward, so that the conveyor belt presses the PE film onto the support belt for transport. This prevents the conveyor belt and PE film from separating during the movement of the hanging plate and the cutter, thus making the cutting and transport of PE film more efficient and stable.

[0014] 2. This utility model uses the rotation of a bidirectional screw and a sliding plate to make a spiral motion, which in turn causes the slide rail to move, thereby changing the spacing between the conveyor belts, so that the device can limit the conveying of PE films of different widths.

The PE film is cut by setting the cutter 9.

[0022] Please see Figures 1-4The conveying mechanism 8 includes a slide rail 81. The slide rail 81 is slidably connected inside the hanging plate 7. A guide rod 82 is slidably connected inside the slide rail 81. The guide rod 82 is fixedly connected to the hanging plate 7. A sliding plate 83 is slidably connected to the upper end of the hanging plate 7. The sliding plate 83 is slidably connected to the guide rod 82. A double-ended screw 84 is threadedly connected inside the sliding plate 83. A limit block 85 is fixedly connected to the upper end of the hanging plate 7. The limit block 85 is slidably connected to the double-ended screw 84. By setting the limit block 85, the double-ended screw 84 is limited. A pressure ring 86 is slidably connected to the outer side of the guide rod 82. The pressure ring 86 contacts the slide rail 81. A compression spring 87 is set on the outer side of the guide rod 82. One end of the compression spring 87 is fixedly connected to the pressure ring 86, and the other end of the compression spring 87 is fixedly connected to the sliding plate 83. By setting the compression spring 87, the pressure ring 86 is elastically compressed. The lower end of the slide rail 81 is fixedly connected to the guide rod 82. A mounting frame 88 is fixedly connected, and a conveyor belt 89 is provided at the lower end of the mounting frame 88. The conveyor belt 89 contacts the support belt 3. The PE film is conveyed by the conveyor belt 89. A hanger 810 is fixedly connected to the upper end of the mounting frame 88. The hanger 810 is slidably connected to the hanger plate 7. A spring 811 is provided on the outside of the hanger 810. One end of the spring 811 contacts the hanger plate 7, and the other end of the spring 811 is fixedly connected to the mounting frame 88. By setting the spring 811, the mounting frame 88 is elastically pressed down. The hanger plate 7 is driven to move by the cylinder 5, which can squeeze the spring 811. The spring 811 elastically squeezes the mounting frame 88 downward, so that the conveyor belt 89 presses the PE film onto the support belt 3 for conveying. This prevents the conveyor belt 89 from separating from the PE film during the movement of the cutter 9 driven by the hanger plate 7, thereby making the cutting and conveying of the PE film more efficient and stable.

[0023] The specific implementation process of this utility model is as follows: In use, the PE film is placed on the support belt 3, and the bidirectional screw 84 and the slide plate 83 are rotated to make a spiral movement, which causes the slide rail 81 to move, thereby changing the spacing between the conveyor belts 89. This allows the device to limit the conveying of PE films of different widths. The drive motor of the conveyor belt 89 is started to drive the conveyor belt 89 to convey the PE film. Then, the cylinder 5 is started, and the cylinder 5 drives the hanger 6 to move. The hanger 6 drives the hanging plate 7 to move. The hanging plate 7 presses the spring 811 downward, and the spring 811 elastically presses the mounting frame 88 downward. The hanging plate 7 drives the cutter 9 to move downward, so that the cutter 9 cuts the PE film. By driving the hanging plate 7 to move through the cylinder 5, the spring 811 can be pressed. The spring 811 elastically presses the mounting frame 88 downward, so that the conveyor belt 89 presses the PE film onto the support belt 3 for conveying. This prevents the conveyor belt 89 and the PE film from separating during the movement of the cutter 9 driven by the hanging plate 7, thereby making the cutting and conveying of the PE film more efficient and stable.
