Description

Technical Field

[0001] The utility model belongs to the technical field of fresh-keeping films, and in particular relates to a roll-shaped fresh-keeping film which is easy to cut. Background Art

[0002] Using plastic wrap to package fruits and vegetables is a simple and effective method of controlled atmosphere preservation. Its principle is to rely on the metabolism of fruits and vegetables themselves to reduce the oxygen concentration in the packaging bag and maintain a certain carbon dioxide concentration and humidity in the bag, so that the fruits and vegetables are in a dormant state, thereby reducing the consumption of nutrients in the body and water evaporation, and extending the shelf life of fruits and vegetables.

[0003] After searching, in the prior art, Chinese patent application number: CN202223007700.2 discloses a fruit and vegetable cling film, including a mounting seat, the outer surface of the mounting seat is fixedly connected to a connecting plate, and the outer surface of one side of the connecting plate near the bottom and the top are fixedly connected to mounting blocks. In the utility model, when the fruit and vegetable cling film is pulled to package the fruits and vegetables, the spring pushes the sliding block to drive the connecting rod to move toward the connecting plate. At this time, while pulling the cling film body, the rotating drum squeezes the cling film body to avoid deformation of the fruit and vegetable cling film, thereby improving the packaging effect. When the fruit and vegetable cling film is broken after packaging the fruits and vegetables, the rotating drum squeezes the head position of the fruit and vegetable cling film by squeezing the connecting plate, thereby solving the problem that the head position of the fruit and vegetable cling film is attached to the cling film body after being torn, resulting in the need to find the head position for the next use, thereby greatly improving the convenience of using the fruit and vegetable cling film.

[0004] However, the device still has the following defects:

[0005] Due to the material properties of the cling film itself, the device has a certain degree of ductility. When in use, it is not easy to tear it open. After the items are packaged for freshness preservation, it is not easy to separate them. The incision is not flat, which affects the next use and is not easy to operate. Utility Model Content

DETAILED DESCRIPTION

[0025] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0026] See also Figure 1-4 The present invention provides a technical solution: a roll of cling film that is easy to cut. It includes a mounting base 110, on which a guide assembly for guiding the cling film is mounted, and a cutting assembly for cutting the cling film is mounted on the guide assembly;

[0027] The cutting assembly includes a second mounting plate 310 and a connecting plate 330. A positioning groove 311 is provided on the second mounting plate 310. A cutter 312 is installed in the positioning groove 311. The height of the cutter 312 is lower than the depth of the positioning groove 311. Second mounting blocks 320 are installed at both ends of the second mounting plate 310. Second movable blocks 331 are installed at both ends of the connecting plate 330. Two groups of second movable blocks 331 are respectively slidably connected to the two groups of second mounting blocks 320. A positioning block 332 for use with the positioning groove 311 is installed at the bottom of the connecting plate 330. A cutting groove 333 for use with the cutter 312 is provided at the bottom of the positioning block 332.

[0028] During use, the cling film body 140 is pulled so that it passes between the two sets of rotating rollers 230, thereby guiding the cling film body 140. After the cling film body 140 is stretched to a desired length, the connecting plate 330 is pressed, causing the connecting plate 330 to move the positioning block 332, which in turn moves the cling film body 140, moving the cling film body 140 into the positioning groove 311. The cling film body 140 is then cut by the cutter 312 in the positioning groove 311, thereby facilitating the cutting of the cling film body 140 and ensuring a smooth cut for subsequent use. The provision of the cutter groove 333 facilitates the cutter 312 in cutting the cling film body 140. Furthermore, the cutter 312 is positioned below the positioning groove 311, preventing the user's hand from being injured when contacting the second mounting block 320, thereby improving the safety of the cutter 312 during use.

[0029] Both sets of second mounting blocks 320 have second movable grooves 321 defined on their sides near the connecting plate 330. Second guide rods 322 are installed within each set of second movable grooves 321, and the two sets of second guide rods 322 are slidably connected to the two sets of second movable blocks 331. Second springs 323 are sleeved onto each set of second guide rods 322. One end of each set of second springs 323 is mounted on the bottom inner wall of each set of second movable grooves 321, and the other end of each set of second springs 323 is mounted on each set of second movable blocks 331. A rotating rod 120 is mounted on the mounting base 110. The plastic wrap body 140 is sleeved onto the rotating rod 120, and a threaded sleeve 130 is threadedly connected to the end of the rotating rod 120 away from the mounting base 110. Through the setting of the second spring 323, after the cutter 312 completes cutting of the cling film body 140, under the elastic action of the second spring 323, the second spring 323 drives the second moving block 331 to move, and the second moving block 331 drives the connecting plate 330 to move, thereby realizing automatic separation of the positioning block 332 and the positioning groove 311, which facilitates the subsequent use of the cling film body 140.

[0030] The guide assembly includes a first mounting plate 210, which is mounted on the mounting base 110, and the first mounting plate 210 is mounted on the second mounting plate 310. First mounting blocks 220 are mounted on both ends of the first mounting plate 210. First movable grooves 221 are defined on opposite sides of the two sets of first mounting blocks 220, and first guide rods 222 are mounted in the two sets of first movable grooves 221. First movable blocks 232 are slidably connected to the two sets of first guide rods 222, and first springs 223 are sleeved on the two sets of first guide rods 222. One end of the two sets of first springs 223 is mounted on the top inner wall of the two sets of first movable grooves 221, and the other end of the two sets of first springs 223 is mounted on the two sets of first movable blocks 232. The guide assembly also includes two sets of connecting rods 231, each rotatably connected to a rotating roller 230. The ends of one set of connecting rods 231 are mounted on two sets of first mounting blocks 220, while the ends of the other set of connecting rods 231 are mounted on two sets of first movable blocks 232. The two sets of rotating rollers 230 guide the cling film body 140, facilitating its extension and use. The first spring 223 allows for adjustment of the spacing between the two sets of rotating rollers 230, allowing them to guide cling film bodies 140 of varying thicknesses.

[0031] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
