[0029] Embodiment 1

[0030] Please refer to Figures 1 to 5 As shown, a plastic wrap cutting device includes a box body 1, a cover body 2 is arranged on the top of the box body 1, fixed blocks 3 are fixedly connected to opposite sides inside the box body 1, a first chute 301 is opened on the outer side of the fixed block 3, a rotating roller 4 is arranged between the two fixed blocks 3, first sliding members 401 are fixedly connected to opposite sides of the rotating roller 4, the rotating roller 4 is slidably connected to the first chute 301 through the first sliding members 401, second notches 402 are annularly opened on the outer surface of the rotating roller 4, inner support mechanisms 5 are arranged in the second notches 402, a connecting plate 6 is fixedly connected to the outer side of the box body 1, a plurality of springs 7 are fixedly connected to the bottom of the connecting plate 6, a pressing plate 8 is fixedly connected to the end of the spring 7 away from the connecting plate 6, a placing plate 9 is fixedly connected to the lower side of the pressing plate 8 and on the outer side of the box body 1, a second chute 601 is opened on the outer side of the connecting plate 6, a second sliding member 10 is slidably connected in the second chute 601, a handle 11 is fixedly connected to the top of the second sliding member 10, a cutting knife 12 for plastic wrap is fixedly connected to the bottom of the second sliding member 10, a third chute 901 is opened on the top of the placing plate 9, a slide block 13 is slidably connected in the third chute 901, the slide block 13 is fixedly connected to the bottom of the cutting knife 12, a film outlet slot 102 is opened on the outer side of the box body 1, and the connecting plate 6 and the placing plate 9 are respectively fixed on the upper and lower sides of the film outlet slot 102.

[0031] In this embodiment, first, the cylindrical plastic wrap is sleeved outside the rotating roller 4, and then the inner wall of the cylindrical plastic wrap is internally supported and tightened by the inner support mechanism 5 to adapt to cylindrical plastic wraps of different sizes. Secondly, the cover 2 is opened, and the cylindrical plastic wrap fixedly sleeved on the rotating roller 4 is slid into the inside of the box body 1 through the chute 301 in the fixing block 3. Then, the rotating roller 4 is rotated, and the plastic wrap on the cylindrical plastic wrap is placed on the top of the placing plate 9 through the film outlet groove 102. At this time, the spring 7 on the lower side of the connecting plate 6 drives the pressing plate 8 to press down, so that the plastic wrap is flattened on the top of the placing plate 9. When the plastic wrap is pulled, wrinkles on the plastic wrap are avoided. When the plastic wrap needs to be cut, since the cutting plate knife 12 has blades on both sides, the user holds the handle and pushes it to the other side, thereby driving the cutting plate knife 12 to cut the plastic wrap.

[0032] Embodiment 2

[0033] Please refer to Figure 3 and Figure 4 As shown in the figure, the inner support mechanism 5 includes a torsion 501. A threaded rod 502 is fixedly connected to the inner side of the torsion 501. The threaded rod 502 penetrates through the notch 402 and is rotatably connected to the inner wall of the rotating roller 4. A plurality of movable blocks 503 are threadedly connected to the outer surface of the threaded rod 502. A connecting column 504 is fixedly connected to the middle of the movable block 503. A clamping block 505 is rotatably connected to the outer surface of the connecting column 504. A connecting column 506 is rotatably connected to the outer side of the clamping block 505. The connecting column 506 is fixedly connected to the inner wall of the rotating roller 4.

[0034] In this embodiment, first, the cylindrical plastic wrap is sleeved outside the rotating roller 4, and then the torsion 501 is rotated, thereby driving the threaded rod 502 to rotate and moving the movable block 503. When the movable block 503 is displaced, due to the linkage effect of the connecting column 504 and the connecting column 506, the clamping block 505 will be driven to open upward and contract inward. When the clamping block 505 opens upward, the inner wall of the cylindrical plastic wrap can be internally supported and tightened. When the clamping block 505 contracts inward, the cylindrical plastic wrap outside the rotating roller 4 can be removed for replacement. The inner support mechanism 5 can not only internally support and tighten the inner diameters of cylindrical plastic wraps of different sizes, but also avoid the problem of poor use effect caused by the misalignment of the cylindrical plastic wrap and the rotating roller 4 when the cylindrical plastic wrap is rotated.

[0035] Embodiment 3

[0036] Please refer to Figure 1 As shown in the figure, a plurality of notches 101 are opened at the top of the box body 1. A pull ring 201 is arranged at the top of the cover 2. A plurality of columns 202 are fixedly connected to the bottom of the cover 2. The columns 202 are slidably connected to the box body 1 through the notches 101.

[0037] In this embodiment, when the box body 1 needs to be opened, the pull ring 201 is pulled upward, and the lower column 202 of the cover body 2 disengages from the first notch 101 of the box body 1, then the box body 1 can be opened. After replacing the tubular plastic wrap, the column 202 is inserted into the first notch 101, and then the cover body 2 is pushed downward to complete the closing of the box body 1, ensuring the cleanliness and hygiene inside the box body 1 and effectively preventing the tubular plastic wrap from being contaminated with dust.

[0038] The working principle and usage process of this device are as follows: First, the tubular plastic wrap is sleeved outside the rotating roller 4, and then the knob 501 is rotated, which drives the threaded rod 502 to rotate, causing the movable block 503 to move. When the movable block 503 displaces, due to the linkage effect of the first connecting column 504 and the second connecting column 506, the clamping block 505 will open upward and contract inward. When the clamping block 505 opens upward, it can internally support and tightly hold the inner wall of the tubular plastic wrap. When the clamping block 505 contracts inward, the tubular plastic wrap outside the rotating roller 4 can be removed for replacement. The internal support mechanism 5 can not only internally support and tightly hold the inner diameters of tubular plastic wraps of different sizes, but also avoid the problem of poor usage effect caused by the dislocation of the tubular plastic wrap and the rotating roller 4 when rotating the tubular plastic wrap. Then, the pull ring 201 is pulled upward, and the lower column 202 of the cover body 2 disengages from the first notch 101 of the box body 1, then the box body 1 can be opened. The tubular plastic wrap fixedly sleeved on the rotating roller 4 slides into the box body 1 through the first chute 301 in the fixing block 3. Then, the rotating roller 4 is rotated, and the plastic wrap on the tubular plastic wrap is placed on the top of the placement plate 9 through the film outlet slot 102. At this time, the spring 7 under the connecting plate 6 drives the pressing plate 8 to press downward, so that the plastic wrap is flattened on the top of the placement plate 9. When the plastic wrap is pulled, wrinkles of the plastic wrap are avoided. When the plastic wrap needs to be cut, since both sides of the cutting board knife 12 are sharpened, the user holds the handle and pushes it to the other side, which can drive the cutting board knife 12 to cut the plastic wrap. After the tubular plastic wrap is used up and replaced, the column 202 is inserted into the first notch 101, and then the cover body 2 is pushed downward to complete the closing of the box body 1, ensuring the cleanliness and hygiene inside the box body 1 and effectively preventing the tubular plastic wrap from being contaminated with dust.

[0039] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present utility model.
