[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0025] The following gives specific embodiments.
[0026] Please refer to Figures 1 - 5, the present utility model provides a cutting device for plastic wrap, including a device main body box 1; a bottom block 23 is slidably connected to the inner wall of the device main body box 1; a plastic wrap placing rod 26 is fixedly connected to the side of the bottom block 23; a pop-up damping rod 24 is fixedly connected to the side of the bottom block 23; the bottom block 23 is fixedly connected to a pop-up spring 25 through the device main body box 1; a clamping end 15 is fixedly connected to the side of the bottom block 23 through the device main body box 1; a damping rod movable block 12 is fixedly connected to the side of the device main body box 1; a spring damping rod 13 is slidably connected to the top of the damping rod movable block 12; the top of the spring damping rod 13 is fixedly connected to a lifting plate 10; the lifting plate 10 is fixedly connected to a reset spring 14 through the damping rod movable block 12; a push plate 9 is fixedly connected to the top of the lifting plate 10; a clamping block 11 is fixedly connected to the bottom of the lifting plate 10; the clamping block 11 is clamped with the clamping end 15; during operation, when the push plate 9 is toggled upwards, the clamping block 11 will move upwards until the clamping block 11 is separated from the clamping end 15. At this time, the bottom block 23 and the plastic wrap placing rod 26 will be pulled by the pop-up spring 25, so that the plastic wrap placing rod 26 quickly disengages from the storage roll, and then the plastic wrap storage roll can be easily taken out. Similarly, during the installation process of the storage roll, the storage roll can be placed into the device main body box 1, and the plastic wrap placing rod 26 is pressed so that the plastic wrap placing rod 26 passes through the storage roll. Until the clamping end 15 jacks up the clamping block 11, the clamping block 11 clamps the clamping end 15.
[0027] Further, as Figure 1 and Figure 3 shown, fixed main body blocks 7 are fixedly connected to both sides of the device main body box 1; air holes 2 are provided in the fixed main body blocks 7; a suction cup 18 is communicated with the bottom of the fixed main body blocks 7; a connecting block 16 is slidably connected to the inner wall of the fixed main body blocks 7; a piston rod 17 is fixedly connected to the bottom of the connecting block 16; the piston rod 17 is slidably connected to the inner wall of the fixed main body blocks 7; a limit damping rod 19 is fixedly connected to the inner bottom wall of the fixed main body blocks 7; the limit damping rod 19 is slidably connected to the connecting block 16; the connecting block 16 is fixedly connected to a return spring 20 through the fixed main body blocks 7. During operation, after the suction cup 18 contacts the desktop, the connecting block 16 is pressed, so that the piston rod 17 pushes out part of the air. At the same time, after the connecting block 16 is released, the return spring 20 will push the piston rod 17 away, so that the air pressure inside the suction cup 18 is reduced, thereby enhancing the adsorption force.
[0028] Further, as Figure 1 and Figure 4As shown in the figure, a cutting track 5 is fixedly connected to the top of the device main body box 1; a limiting block 21 is slidably connected to the inner wall of the cutting track 5; a cutting blade 22 is fixedly connected to the top of the limiting block 21; a pressing block 6 is fixedly connected to the top of the cutting blade 22; a magnetic block 8 is fixedly connected to the top of the device main body box 1; an opening and closing cover 3 is rotatably connected to the side of the device main body box 1; an iron plate 4 is height-connected to the side of the opening and closing cover 3. During operation, after the plastic wrap is pulled through the cutting track 5, the pressing block 6 can be slid, so that the cutting blade 22 cuts across the plastic wrap, and thus the plastic wrap is cut by the cutting blade 22, thereby achieving the purpose of cutting the plastic wrap.
[0029] Working principle: When the push plate 9 is toggled upward, the clamping block 11 will move upward until the clamping block 11 is separated from the clamping end 15. At this time, the bottom block 23 and the plastic wrap placing rod 26 will be pulled by the pop-up spring 25, so that the plastic wrap placing rod 26 quickly disengages from the storage roll, and thus the plastic wrap storage roll can be easily taken out. Similarly, during the installation of the storage roll, the storage roll can be placed into the device main body box 1, and the plastic wrap placing rod 26 is pressed so that the plastic wrap placing rod 26 passes through the storage roll. Until the clamping end 15 pushes up the clamping block 11, the clamping block 11 clamps the clamping end 15. After the suction cup 18 contacts the desktop, the connecting block 16 is pressed, so that the piston rod 17 pushes out part of the air. At the same time, after the connecting block 16 is released, the return spring 20 will push the piston rod 17 away, thereby reducing the air pressure inside the suction cup 18, thereby enhancing the adsorption force. After the plastic wrap is pulled through the cutting track 5, the pressing block 6 can be slid, so that the cutting blade 22 cuts across the plastic wrap, and thus the plastic wrap is cut by the cutting blade 22, thereby achieving the purpose of cutting the plastic wrap.
[0030] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention.
