Description

A high-transparency, scratch-resistant PET film Technical Field

[0001] This utility model relates to the field of film technology, and more specifically, to a high-transparency, scratch-resistant PET film. Background Technology

[0002] The main raw material of PET film is LLDPE, which is relatively soft and has a certain degree of stretchability. The thickness is generally 0.0mm-0.15mm, and its adhesion varies from 5G to 500G depending on the application requirements (the classification of adhesion is different in China and abroad. For example, 200g of Korean film is equivalent to about 80g in China). PE protective film projects also include electrostatic film, textured film, etc.

[0003] The present invention discloses a high-temperature resistant, heat-resistant, and heat-resistant PET film, belonging to the field of film technology. It includes a PET film body with transparent silicone strips at both the top and bottom, located on the outer side of the PET film body. The two ends of the transparent silicone strips are connected to each other. A PC sheet is placed on top of the transparent silicone strips, and transparent glass fiber filaments are placed between the bottom of the PC sheet and the transparent silicone strips. The transparent silicone strips and PC sheet on the surface of the PET film body form an outer protection, providing heat insulation and improving the film's heat insulation and heat-resistant softening effect during use. Furthermore, the conical heat dissipation holes on the transparent silicone strips allow heat to dissipate outwards while preventing external heat from diffusing inwards, resulting in even better heat insulation.

[0004] Based on this, we agree with the advantages of the aforementioned products, but the following drawbacks still exist:

[0005] Traditional PET film has poor transparency, which affects its abrasion resistance and structural transparency strength during use. It also makes it difficult to see scratches. Furthermore, the low transparency of PET film affects the use of subsequent objects to which the film is applied, and the insufficient transparency leads to a decrease in light transmission. Summary of the Invention

[0006] The purpose of this invention is to provide a high-transparency, scratch-resistant PET film to solve the problem in the background art where the poor transparency of traditional PET films leads to abrasion resistance affecting the structural transparency strength and poor scratch resistance.

[0007] This utility model embodiment provides a high-transparency scratch-resistant PET film, including a support mechanism. The support mechanism includes a Z-shaped bracket supported by the ground. Connecting crossbars are installed horizontally at both ends of the Z-shaped bracket. A motor mounting rod is installed horizontally at the middle of the ends of the two connecting crossbars. A connecting upright is installed vertically at the middle of the end of the motor mounting rod. A motor mounting seat is installed horizontally at the middle of the top of the connecting upright. A drive motor is installed at the middle of the top of the motor mounting seat. A winding drum is driven at the output end of the drive motor.

[0008] As a preferred embodiment of this utility model: a film conveying air duct is provided at the middle of the end of the winding cylinder, an I-shaped frame is provided at the middle of the top of the film conveying air duct, and a concave groove is provided at the middle of the end of the I-shaped frame.

[0009] As a preferred embodiment of this utility model: one end of the concave slot is provided with a PET film mechanism;

[0010] The PET film structure includes an outer covering layer disposed in a concave groove, and a toughening film layer at the bottom center of the outer covering layer.

[0011] As a preferred embodiment of the present invention: a plurality of adjustment holes are provided on the surface of the toughening film layer, a central toughening plate is provided at the bottom center of the plurality of adjustment holes, an adjustment groove is provided in the center of the central toughening plate, and a toughening strip is arranged transversely in the center of the groove of the adjustment groove.

[0012] As a preferred embodiment of the present invention: a plurality of the central toughening sheets are evenly distributed on the surface of the central toughening sheets, the bottom surface of the outer covering layer is provided with an anti-scratch layer, and the bottom center of the central toughening sheet is provided with a transparent PET film layer.

[0013] As a preferred embodiment of the present invention: a lower support layer is installed at the bottom of the transparent layer of the PET film, and a plurality of adjustment plates are sequentially opened on the bottom surface of the lower support layer, and a plurality of adjustment openings are sequentially opened on the surface of the adjustment plates.

[0014] As a preferred embodiment of this utility model, several adjustment bases are attached to both sides of the adjustment plate.

[0015] As a preferred embodiment of this utility model, a protective mesh layer is installed at the bottom center of the lower bearing layer.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1) The support is achieved by using a zigzag bracket and connecting horizontal bar. The support is formed between the connecting vertical bar and the motor mounting base. The motor mounting base restricts the drive motor to ensure the forward and backward movement of the conveying PET film, which drives the internal roller of the winding drum to rotate, making it easy to transfer and move to the outer coating layer for extraction and use.

[0018] 2) The outer coating layer and toughening film layer adopted improve the bonding of the layer structure of the PET film. One end of the toughening strip is used to achieve the mutual bonding of the corresponding PET film layers. The unified combination of the lower bearing layer and the lower protective mesh layer improves the protective wear resistance of the PET film, strengthens the light transmission, and is more suitable for electronic light transmission characteristics, avoiding excessive light blocking and affecting the use.

Motor mounting rods 13 are installed horizontally at the middle of the ends of the two connecting crossbars 12. Connecting uprights 14 are installed vertically at the middle of the ends of the motor mounting rods 13. A motor mounting seat 15 is installed horizontally at the middle of the top of the connecting uprights 14. A drive motor 16 is installed at the middle of the top of the motor mounting seat 15. A winding drum 17 is driven at the output end of the drive motor 16.

[0033] In this embodiment: a film conveying air duct 18 is provided at the middle of the end of the winding cylinder 17, an I-shaped frame 19 is provided at the middle of the top of the film conveying air duct 18, and a concave groove 191 is provided at the middle of the end of the I-shaped frame 19.

[0034] The film conveying duct 18 and I-shaped frame 19 used ensure the material of the PET film and achieve uniform discharge of the outer coating layer 21.

[0035] In this embodiment: a PET film mechanism 2 is provided at one end of the concave slot 191;

[0036] The PET film structure 2 includes an outer covering layer 21 disposed in a concave slot 191, and a toughening film layer 22 at the bottom center of the outer covering layer 21.

[0037] The PET film is moved by a concave groove 191, and the film is transferred along the outer covering layer 21.

[0038] In this embodiment: a plurality of adjustment holes 23 are provided on the surface of the toughening film layer 22, a central toughening plate 24 is provided at the bottom center of the plurality of adjustment holes 23, an adjustment slot 25 is provided in the center of the central toughening plate 24, and a toughening strip 26 is arranged horizontally in the center of the slot of the adjustment slot 25.

[0039] The use of a central toughening sheet 24 and an adjustment slot 25 increases the toughness of the film, and contact is achieved through the slotted end of the adjustment slot 25.

[0040] In this embodiment: a plurality of central toughening sheets 24 are evenly distributed on the surface of the central toughening sheet 24, the bottom surface of the outer covering layer 21 is provided with an anti-scratch layer 27, and the bottom center of the central toughening sheet 24 is provided with a PET film transparent layer 28.

[0041] The transparent layer 28 of the PET film used avoids blocking the light transmitted through at one end of the film layer.

[0042] In this embodiment: a lower support layer 29 is installed at the bottom of the transparent layer 28 of the PET film, and a plurality of adjustment plates 291 are sequentially opened on the bottom surface of the lower support layer 29, and a plurality of adjustment openings 292 are sequentially opened on the surface of the adjustment plates 291.

[0043] The adjustment plate 291 and several adjustment openings 292 are used to form an interchange of light intensity between the openings, thus avoiding light shading.

[0044] In this embodiment, several adjustment bases 293 are attached to both sides of the adjustment plate 291.

[0045] The adjustment base 293 is used to improve the scratch resistance and wear resistance of the body.

[0046] In this embodiment, a protective mesh layer 294 is installed at the bottom center of the lower bearing layer 29.

[0047] In practical use, the first step is to ensure the tightening and rotation of the support mechanism 1.

[0048] At this time, the user supports the zigzag bracket 11, uses the connecting horizontal bar 12 to distribute the load, connects the motor mounting rod 13 on the side wall, and achieves vertical support through one end of the connecting vertical rod 14. According to the support connection, the corresponding drive motor 16 is fixed by the limit of the motor mounting seat 15, ensuring that the end of the motor output shaft does not spin freely.

[0049] After the PET film is rolled inside the winding drum 17, it is discharged from one end of the film conveying duct 18. The film is discharged from the outer covering layer 21 through one end of the film conveying duct 18. It is fixed according to one end of the I-frame 19 and covered with a high-transparency, scratch-resistant structure by the central toughening sheet 24.

[0050] At this point, the toughening strip 26 and the slot of the adjusting groove 25 are used to achieve assembly;

[0051] Through the layer structure of the corresponding PET film transparent layer 28;

[0052] Step 2: By bonding the corresponding toughening strips 26 and the corresponding central toughening sheets 24 together, the toughening strength changes using the transparent layer 28 of the PET film.

[0053] At this point, the surface of the corresponding protective mesh layer 294 is covered to ensure that the transparency of the PET film inside is not affected too much. The surface of the bottom protective mesh layer 294 is scratch-resistant. At this point, the user uses the outer covering layer 21 and the surface of the toughening film layer 22 to perform bonding and assembly. While the light transmission and scratch resistance are not affected, the wear resistance is also correspondingly improved.
