[0001] This utility model relates to the field of PVC plastic film technology, specifically to an environmentally friendly and stable PVC plastic film. Background Technology

[0002] PVC film is a synthetic material made by calendering or blow molding. Its thickness is usually between 0.08 and 0.2 mm. It is mainly used in building materials, packaging and daily necessities. In building materials, PVC film is used as a decorative film or adhesive film. It is bonded to the surface of the board through a high temperature vacuum pressing process and is used for the surface packaging of furniture, cabinets and other items. It has the characteristics of being anti-detachment and weather-resistant, and its service life can reach more than 10 years.

[0003] For example, Chinese patent (publication number: CN220976860U) discloses a tear-resistant PVC film, including a tear-resistant base layer, which includes PVC and a mesh. The mesh is located inside the PVC and includes warp and weft threads, both of which are arranged in a wavy pattern. A wear-resistant layer is provided above the tear-resistant base layer. This utility model adds a wavy mesh inside the PVC film, which can both allow the PVC film to be stretched to a certain extent and limit the maximum stretch of the PVC film to avoid excessive stretching and breakage.

[0004] However, this PVC film is not environmentally friendly enough. Although the acrylic fiber used in it can guarantee strength, it is difficult to recycle and is not environmentally friendly enough. Therefore, an environmentally friendly and stable PVC plastic film is proposed to solve the above problems. Summary of the Invention

[0023] Referring to Figures 1 to 3 below, an environmentally friendly and stable PVC plastic film in this embodiment includes a support 1. A rotating rod 2 is rotatably connected to the inner side of the support 1 via a bearing. The rotating rod 2 can provide stable support for the plastic film body 4. The plastic film body 4 is provided on the outer surface of the rotating rod 2. A cutting component 3 that can smoothly cut the plastic film body 4 is provided on the inner side of the support 1 and below the rotating rod 2.

[0024] In addition, the bracket 1 includes a base plate 101, and two side plates 102 are fixed on the top of the base plate 101. The base plate 101 and the two side plates 102 cooperate to ensure the stable rotation of the rotating rod 2 and provide the necessary support force for the cutting component 3. The opposite side of the two side plates 102 is rotatably connected to the rotating rod 2 through bearings.

[0025] In addition, the cutting assembly 3 includes a limiting shell 301 fixed to one side opposite to the two side plates 102. A serrated blade 302 is movably connected to the inner side of the limiting shell 301. When the serrated blade 302 moves, the protruding head on the serrated blade 302 can pierce the plastic film body 4, improving the cutting efficiency. Connecting pieces 303 are fixed on both the front and rear sides of the serrated blade 302. The two connecting pieces 303 pass through the two side plates 102 respectively. A lever 304 located outside the bracket 1 is fixed on the side of the two connecting pieces 303 away from the serrated blade 302. The lever 304 makes it easy for the user to use.

[0026] It is understood that the limiting shell 301 includes an arc-shaped inner plate 3011 fixed to the two side plates 102. The arc-shaped inner plate 3011 and the arc-shaped outer plate 3012 are both fixed by the two side plates 102. The limiting shell 301 can limit the serrated blade 302. An arc-shaped outer plate 3012 located outside the arc-shaped inner plate 3011 is also fixed between the two side plates 102. The serrated blade 302 is located between the arc-shaped inner plate 3011 and the arc-shaped outer plate 3012. The serrated blade 302 is movably connected to the arc-shaped inner plate 3011 and the arc-shaped outer plate 3012.

[0027] Furthermore, each side plate 102 is provided with a moving groove that penetrates the side plate 102. The moving groove can ensure that the connecting piece 303 can smoothly penetrate the two side plates 102. Each moving groove is connected to the gap between the arc-shaped inner plate 3011 and the arc-shaped outer plate 3012. Each moving groove is arc-shaped. The two connecting pieces 303 penetrate the two side plates 102 through the two moving grooves respectively. When the toggle block 304 is moved, the external force is transmitted to the serrated blade 302 through the connecting piece 303, which easily causes the serrated blade 302 to pierce the plastic film body 4.

[0028] In this embodiment, the bracket 1 provides the necessary support force for the rotating rod 2 to ensure that the rotating rod 2 rotates stably. When it is necessary to cut the plastic film body 4, the serrated blade 302 is driven to rotate stably by the toggle block 304 to puncture the plastic film body 4 smoothly.

[0029] Please refer to Figures 1 and 4 again. In order to improve the waterproof effect, the plastic film body 4 in this embodiment includes a tensile layer 403. A connecting layer 402 is fixed on both the inner and outer sides of the tensile layer 403. The connecting layer 402 is used to connect the waterproof layer 401 and the absorbent layer 404 to the tensile layer 403. The waterproof layer 401 is fixed on the side of the outer connecting layer 402 away from the tensile layer 403, and the absorbent layer 404 is fixed on the side of the inner connecting layer 402 away from the tensile layer 403.

[0030] It should be further explained that the tensile layer 403 includes two reinforcing layers 4032, which are fixed to two connecting layers 402 respectively. The reinforcing layers 4032 can improve the overall strength of the plastic film. A printed layer 4031 is fixed to the inner side of the two reinforcing layers 4032, which serves an aesthetic purpose.

[0031] In addition, the waterproof layer 401 is a water-based polyurethane coating, which is an environmentally friendly material that uses water as a dispersion medium and has a good waterproof effect. The bonding layer 402 is a water-based acrylic adhesive, which has good adhesion, is less affected by temperature, and has good acid and alkali resistance, water resistance and weather resistance. It is suitable for humid environments or scenarios where chemical media are present. The reinforcing layer 4032 is agave fiber, which has good strength and is relatively environmentally friendly. The adsorption layer 404 is an electrostatic film, which achieves glue-free bonding through electrostatic charge adsorption and is recyclable, making it more environmentally friendly.

[0032] In this embodiment, the plastic film body 4 is adsorbed to the item by the adsorption layer 404, which can ensure that the plastic film body 4 adheres more tightly to the item. At the same time, the waterproof layer 401 can play a waterproof role, improving the protection of the item.

[0033] It is understandable that the plastic film body 4 is made of relatively environmentally friendly materials. At the same time, by cooperating with the rotating rod 2 and the cutting component 3, it is possible to take only the required amount, which can reduce unnecessary waste, thereby reducing the wear and tear of the plastic film body 4 and further improving the environmental protection effect.

[0034] The working principle of the above embodiments is as follows:

[0035] When using the product, first pull out the plastic film body 4. At this time, the rotating rod 2 will rotate. When the desired length is reached, the user presses the pulled-out plastic film body 4 with both thumbs, presses the plastic film body 4 wrapped around the surface of the rotating rod 2 with both index fingers, and pulls the lever 304 with both middle fingers. At this time, the lever 304 will drive the connecting piece 303 and the serrated blade 302 to move towards the plastic film body 4. When the serrated blade 302 moves out of the limiting shell 301, it will pierce the plastic film body 4, and the user can easily remove the desired length. This method can reduce unnecessary waste and thus effectively improve environmental protection.

[0036] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
