Description

Technical Field

[0001] This utility model relates to the field of paperless label production technology, and in particular to a paperless label and release mechanism. Background Technology

[0002] Traditional self-adhesive labels typically consist of three layers: a top layer, a pressure-sensitive adhesive layer, and a release liner. To use them, the release liner is peeled off to expose the adhesive layer, allowing for easy application. This structure has a significant drawback: the release liner is discarded as waste, wasting resources, increasing costs, and harming the environment. Statistics show that the release liner accounts for approximately 30%-50% of the total label material's weight and volume, making its disposal an environmental issue.

[0003] To address this issue, the concept of "backing paper-free labels" has emerged in the market. The basic principle is to directly coat the adhesive layer with a layer of silicone oil, which cures to form a release layer, thus eliminating the need for traditional backing paper. However, existing backing paper-free labels face some challenges in practical applications: Difficult to grasp: Because there is no backing paper, the labels are isolated from each other by a silicone oil layer, and the surface is very smooth, making it difficult for operators to use their fingers to smoothly separate and grasp the first label from the label roll or label pile.

[0004] Easy to stick together: Under high temperature and high pressure environment, the isolation effect of silicone oil layer may decrease, causing labels to stick together and affecting normal label dispensing.

[0005] Therefore, there is an urgent need for an improved backing paper label structure to solve the above problems. Utility Model Content

[0006] In order to solve the problems mentioned in the background art, the present invention provides a backing paper-free label and release mechanism.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A backingless label includes a face layer and an adhesive layer disposed on the back of the face layer, and also includes a silicone oil curing layer and a release liner. The silicone oil curing layer covers the back of the adhesive layer; The release liner can be peelably laminated to the back of the silicone oil cured layer; The edge of the surface layer is provided with a glue-free area where the adhesive layer is not applied, and the glue-free area extends to the edge of the label to form a gripping part.

[0008] Preferably, the glue-free area is a notch at the corner of the surface layer or a strip-shaped area along the side of the surface layer.

[0009] Preferably, the release liner is a smooth plastic film.

[0010] A backing paper-free label release mechanism includes a frame, an unwinding roller, a rewinding roller, a drive unit, and a peeling blade; The unwinding roll and the winding roll are arranged in parallel on the frame; The drive unit is connected to the winding roller and is used to drive it to rotate; The peeling blade is mounted on the frame, and its tip contacts the moving path of the release liner to pry the adhesive-free area of ​​the label off the release liner.

[0011] Preferably, it also includes a detection unit and a controller; The detection unit is mounted on the frame and is used to detect whether the label has reached the preset peeling station; The controller is electrically connected to the detection unit and the drive unit, and is configured as follows: Preferably, when the detection unit detects that the tag has arrived at the peeling station, it controls the drive unit to stop running; Preferably, when the detection unit detects that a tag has been removed, it controls the drive unit to operate so as to transport the next tag to the peeling station.

[0012] Preferably, the detection unit is a photoelectric sensor.

[0013] Preferably, the drive unit is a motor.

[0014] Preferably, the release liner is drawn out by the unwinding roller, passes around the peeling blade 53, and its end is fixed to the winding roller.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. By setting a glue-free area on the edge of the label as a gripping part, users can easily pinch this part with their fingers to separate the label from the release liner or label stack, solving the problem of difficult gripping of traditional backing paper labels.

[0016] 2. It retains the core advantages of paperless labels, saves a lot of paper, reduces raw material costs and waste disposal costs, and is more environmentally friendly.

[0017] 3. The silicone oil curing layer, combined with the reusable release liner, ensures stable and reliable isolation between labels, avoiding adhesion problems caused by high temperature and high pressure during storage and transportation.

[0018] 4. The release mechanism makes it easier to remove the label and rewind the used release liner.

[0019] In summary, this utility model, by adding an adhesive-free gripping part and a recyclable release liner, not only completely eliminates the need for traditional backing paper, thus achieving environmental protection, but also solves the core pain point of difficulty in gripping labels without backing paper, and has high social use value and application prospects.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example 1

[0024] Reference Figure 1-2 A backingless label comprises, from top to bottom, a surface layer 1, an adhesive layer 2, a silicone oil curing layer 3, and a release liner 4. The surface layer 1 can be made of conventional label materials such as coated paper, PET, or PE. The adhesive layer 2 is a pressure-sensitive adhesive. The silicone oil curing layer 3 is formed by coating and curing, with a thickness of approximately 5 micrometers. Its side in contact with the release liner 4 (in this example, a PET film) is very smooth, thus achieving the release function.

[0025] At the upper right corner of the surface layer 1, there is a strip-shaped adhesive-free area 11. This area is masked when the adhesive is applied, so there is no adhesive residue. This adhesive-free area 11 extends to the edge of the label, forming a gripping part that is convenient for the user to pinch with their fingers.

[0026] The release liner 4, through its temporary bonding with the silicone oil curing layer 3, ensures that the adhesive side (i.e., the silicone oil side) of the label does not directly contact the back (usually the top layer) of the next label when it is in roll or stacked state, thus completely avoiding adhesion problems during storage and transportation. This release liner is reusable, with one sheet used for the entire roll of labels, unlike traditional labels where each sheet has a discarded backing paper.

[0027] When a user needs to retrieve a label, their fingers can easily pinch the "gripping area" formed by the adhesive-free zone 11. Since there is no adhesive here, the fingers will not encounter any sticky resistance and can easily "lift" one corner of the label from the release liner 4. Once one corner of the label is lifted, the remaining part with the adhesive and silicone oil layer can be smoothly peeled off the release liner 4 as a whole.

[0028] A release mechanism for a backing paper label includes a frame 5, with an unwinding roller 51 and a take-up roller 52 arranged in parallel on the frame 5. The backing paper label is placed on the unwinding roller 51, and one end of the release liner 4 is connected to the take-up roller 52. A motor 511 is provided on the side wall of the frame 5, and the output end of the motor 511 is fixedly connected to the take-up roller 52. A peeling blade 53 is provided on the inner side wall of the frame 5, and the tip of the peeling blade 53 contacts the upper surface of the release liner 4.

[0029] Furthermore, a photoelectric sensor 54 is provided on the frame 5 above the label without a backing paper, and a controller 55 is also provided on the side wall of the frame 5. The controller 55, the photoelectric sensor 54 and the motor 511 are electrically connected.

[0030] When labeling, the start motor 511 drives the unwind roller 51 to rotate, thereby moving the backing paper label. The peeling blade 53 will lift the adhesive-free area 11. At this time, the photoelectric sensor 54 detects that the label is below the photoelectric sensor 54 and controls the motor 511 to stop. When the staff peels off the label, the photoelectric sensor 54 detects that there is no label below. The controller 55 controls the backing paper label to move a certain distance, and the peeling blade 53 will lift the adhesive-free area 11 of the next label.
