Description

Technical Field

[0001] The utility model relates to the technical field of transfer films, in particular to a pre-coated plastic removal transfer film. Background Art

[0002] Transfer film is an intermediate carrier that exists on a transfer paper base or a plastic base. It carries the printed or printed pattern and is a chemical elastic film used to transfer it to the printed object.

[0003] For example, a Chinese utility model provides "a friction-resistant transfer film", with the announcement number: CN218112165U. The application includes a peeling layer, an adhesive layer, a transfer layer and a protective layer. The peeling layer, adhesive layer and transfer layer are arranged in sequence, and the protective layer is U-shaped. The peeling layer, adhesive layer and transfer layer form a whole located on the inner side of the protective layer. In the utility model, the transfer body formed by the peeling layer, adhesive layer and transfer layer is processed through the protective layer, and then the protective layer is opened, the transfer body is placed in the protective layer, and then the protective layer is closed so that the inner surface of the protective layer is adsorbed on the outer surface of the transfer body to form a whole. When in use, the protective layer is torn off first, and then the transfer film can be used according to the normal use steps. This effectively avoids the imaging layer from directly contacting the external environment, and is easily damaged by external bumps, collisions and friction, thereby affecting the imaging quality of the transfer film.

[0004] The transfer film in the above technology uses PET film and PVC film as the peeling layer and base layer respectively during use. Since PET film and PVC film cannot be degraded in nature, they are likely to cause significant pollution to the environment when discarded as garbage. At the same time, due to the lack of an effective reinforcement structure inside the transfer film, it is easy to tear due to force during use, which is not conducive to human use. Utility Model Content

[0005] The purpose of the utility model is to provide a pre-coated plastic removal transfer film, which has the advantages of good degradability, reducing environmental pollution and improving overall tear resistance.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a pre-coated plastic removal transfer film, comprising a roll, a transfer film body wound on the middle end of the outer surface of the roll, the transfer film body comprising a PBAT film layer, a reinforcing layer bonded to the top of the PBAT film layer, a PLA film layer bonded to the top of the reinforcing layer, the right end of the inner cavity of the roll is movably connected to a support frame, the bottom of the support frame is fixedly connected to a bottom plate, both ends of the left side of the bottom plate are movably connected to sliding rods, a connecting frame is fixedly connected between the left sides of the two sliding rods, the upper end of the connecting frame is fixedly connected to a support shaft, and the right end of the support shaft is movably connected to the left end of the inner cavity of the roll.

[0007] As a preferred solution, a pin hole is provided at the top of the sliding rod, and a U-shaped pin rod is movably connected between the surface of the pin hole and the left end of the top of the base plate. The upper ends of both sides of the U-shaped pin rod are fixedly connected to a fixing plate, and a support spring is fixedly connected between the bottom of the fixing plate and the left end of the top of the base plate.

[0008] As a preferred solution, a support block is fixedly connected to the bottom of the connecting frame, and the number of the support blocks is two.

[0009] As a preferred solution, a fixing tape is fixedly connected to the top of the transfer film body, and the number of the fixing tapes is three.

[0010] As a preferred solution, the bottom of the PBAT film layer is coated with an EVA film layer, and the bottom of the EVA film layer is bonded with a release paper layer.

[0011] As a preferred solution, the reinforcement layer is formed by interweaving polyamide fibers and aramid fibers in warp and weft, wherein the polyamide fibers are warp threads and the aramid fibers are weft threads.

[0012] As a preferred solution, the top of the PLA film layer is coated with a PU coating.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] The utility model can support the roll and the transfer film body through the arrangement of the support shaft, the connecting frame, the sliding rod, the bottom plate and the support frame, and can enable the roll to rotate along the surface of the support shaft and the support frame during the process of personnel unwinding and using the transfer film body, which brings great convenience to personnel. Through the arrangement of the reinforcement layer, since the polyamide fiber and the aramid fiber in the reinforcement layer have good strength, good strength protection is formed inside the transfer film body, which effectively reduces the probability of tearing of the transfer film body due to force during use. At the same time, through the arrangement of the PLA film layer and the PBAT film layer, since the PLA film layer and the PBAT film layer have a degradable effect, they can be decomposed under natural conditions, thereby effectively reducing the pollution caused to the environment and improving the environmental protection effect of the use of the transfer film body.

[0015] The U-shaped pin is pulled upward to move the fixed plate, which in turn stretches the support spring until the U-shaped pin is disengaged from the surface of the pin hole, thereby releasing the limit of the slide bar. Subsequently, the slide bar, the connecting frame and the support shaft can be pulled to the left to enable the support shaft to be disengaged from the left side of the reel, thereby making it convenient for personnel to remove and replace the reel after the transfer film body is used up. By setting the support block, the connecting frame can be The bottom of the transfer film is supported, and the setting of the fixing tape can be used to stick and fix the end of the transfer film body to prevent the transfer film body from becoming loose due to rotation and unwinding. The setting of the EVA film layer is convenient for personnel to stick and transfer the printed or printed patterns. The setting of the release paper layer can effectively protect the bottom of the EVA film layer to prevent dust from adhering to the quality of the subsequent use of the EVA film layer. At the same time, personnel can peel off the release paper layer from the bottom of the EVA film layer during subsequent use, which is convenient for personnel to use. The setting of the PU coating effectively improves the anti-fouling and wear-resistant effect of the top of the transfer film body. BRIEF DESCRIPTION OF THE DRAWINGS

The upper end of the connecting frame 6 is fixedly connected to a support shaft 3, and the right end of the support shaft 3 is movably connected to the left end of the inner cavity of the reel 9.

[0025] In the present technical solution, the support shaft 3, the connecting frame 6, the sliding rod 7, the bottom plate 8 and the support frame 10 are arranged to support the reel 9 and the transfer film body 1, and the reel 9 can be rotated along the surface of the support shaft 3 and the support frame 10 during the process of personnel unwinding the transfer film body 1, which brings great convenience to personnel. Through the arrangement of the reinforcement layer 103, since the polyamide fiber 1031 and the aramid fiber 1032 in the reinforcement layer 103 have good strength, good strength protection is formed inside the transfer film body 1, which effectively reduces the probability of tearing due to force during the use of the transfer film body 1. At the same time, through the arrangement of the PLA film layer 102 and the PBAT film layer 104, since the PLA film layer 102 and the PBAT film layer 104 have a degradable effect, they can be decomposed under natural conditions, thereby effectively reducing the pollution caused to the environment and improving the environmental protection effect of the use of the transfer film body 1. Example

[0026] On the basis of embodiment 1, the present invention is as follows Figure 1-Figure 5As shown, a pin hole 13 is disclosed at the top of the sliding rod 7, and a U-shaped pin rod 5 is movably connected between the surface of the pin hole 13 and the left end of the top of the bottom plate 8. The upper ends of both sides of the U-shaped pin rod 5 are fixedly connected with a fixing plate 11, and a supporting spring 12 is fixedly connected between the bottom of the fixing plate 11 and the left end of the top of the bottom plate 8. The bottom of the connecting frame 6 is fixedly connected with a support block 4, and the number of support blocks 4 is two. The top of the transfer film body 1 is fixedly connected with a fixing tape 2, and the number of fixing tapes 2 is three. The bottom of the PBAT film layer 104 is coated with an EVA film layer 105, and the bottom of the EVA film layer 105 is bonded with a release paper layer 106. The reinforcing layer 103 is formed by interweaving polyamide fiber 1031 and aramid fiber 1032 in warp and weft. The polyamide fiber 1031 is the warp, and the aramid fiber 1032 is the weft. The top of the PLA film layer 102 is coated with a PU coating 101.

[0027] When the U-shaped pin 5 is pulled upward, the fixing plate 11 is driven to stretch the supporting spring 12 until the U-shaped pin 5 is disengaged from the surface of the pin hole 13, thereby releasing the limit of the slide bar 7. Subsequently, the slide bar 7, the connecting frame 6 and the support shaft 3 can be pulled to the left, so that the support shaft 3 can be disengaged from the left side of the reel 9, thereby making it convenient for the personnel to remove and replace the reel 9 after the transfer film body 1 is used up.
