[0002] Labels need to be pasted on some packaging boxes. Most labeling machines can label on a single plane or a cylindrical surface. Some packaging boxes need to be sealed, so one label needs to be pasted on two surfaces at the same time. CN210653980U discloses a right-angle corner labeling device, which realizes labeling on two surfaces through a vertical labeling component and a horizontal labeling component. This labeling device needs to rely on a suction cup to adsorb the label to the box body for labeling, and cannot perform continuous labeling well. Content of the Utility Model

[0024] The utility model has the following beneficial effects: The tape conveying mechanism moves the tape, and conveys the labels attached to the tape one by one to the position where the opening is located. When the tape is folded by the peeling knife, a part of the label will be peeled off from the tape by the peeling knife. At this time, the pressing plate will press the unpeeled part of the label on the tape to prevent the label from being completely peeled off by the peeling knife. And when the label is uneven, the label will be flattened by the pressing plate when passing through the pressing plate, preventing unevenness during labeling. The product moves towards the elastic labeling plate, and the label abuts against the elastic labeling plate. The elastic labeling plate will be squeezed by the product and press the label on the product. When the product continues to move, it will pull the label and further peel the unpeeled label from the tape so as to stick it on another surface.

[0031] Please refer to Figures 1-3 As shown, the specific embodiment of this utility model provides a double-sided labeling machine, and the labeling machine includes a machine shell 10, an elastic labeling plate 20, a tape conveying mechanism 30, a peeling knife 40, and a pressing plate 50. The machine shell 10 has an inner cavity, and the tape conveying mechanism 30, the peeling knife 40, and the pressing plate 50 are installed in the inner cavity.

[0032] The machine shell 10 has a panel 11, and this panel 11 includes an operation surface 111 and a back surface 112, and the product moves along the operation surface 111. In this embodiment, the operation surface 111 is an inclined surface to facilitate the operator to control the product to move along the operation surface 111. An adjustable limit plate 114 is provided on the panel 11, and the limit plate 114 is used for the side alignment of the product during labeling.

[0033] The back surface 112 is located in the inner cavity. An opening 113 that penetrates the operation surface 111 and the back surface 112 is provided on the panel 11.

[0034] The tape conveying mechanism 30 includes a reel 31, a plurality of rollers 32, a motor 33, and a driving roller 34. The reel 31 is used to place the tape roll. The rollers 32 are used for guiding the tape 100. The motor 33 is connected to the driving roller 34, and the driving roller 34 is used to move the tape 100, so as to convey the labels on the tape 100.

[0035] The peeling knife 40 is arranged at the position where the opening 113 is located, on the back side of the tape 100. The tape 100 will pass through the peeling knife 40 during the conveying process and will fold after passing through the peeling knife 40. When the label moves to the peeling knife 40, a part of the label will be peeled off from the tape 100, and the peeled label will extend out of the opening 113 to the operation surface 111.

[0036] The pressing plate 50 is arranged on the side of the tape 100 where the label is attached, and is opposite to the peeling knife 40. Along the conveying direction X, the pressing plate 50 is located behind the peeling knife 40. The pressing plate 50 presses the unpeeled part of the label on the tape 100.

[0037] The elastic label pasting plate 20 can be installed on the panel 11. It can be moved by being squeezed by the product. Along the moving direction Y in which it is squeezed and moved, the elastic label pasting plate 20 is located in front of the peeled label. The elastic label pasting plate 20 is used to abut against the part of the label that extends out of the opening 113.

[0038] The tape 100 is moved by the tape conveying mechanism 30, and the labels attached to the tape 100 one by one are conveyed to the position where the opening 113 is located. When the tape 100 folds after passing through the peeling knife 40, a part of the label will be peeled off from the tape 100 by the peeling knife 40. At this time, the pressing plate 50 will press the unpeeled part of the label on the tape 100 to prevent the label from being completely peeled off by the peeling knife 40. And when the label is uneven, the label will be smoothed by the pressing plate 50 when passing through the pressing plate 50 to prevent unevenness during label pasting. The product moves towards the elastic label pasting plate 20, and the label abuts against the elastic label pasting plate 20. The elastic label pasting plate 20 will be squeezed by the product and press the label on the product. When the product continues to move, it will pull the label and further peel the unpeeled label from the tape 100 so as to paste it on another surface. During the process of pulling the label away from the tape 100, the pressing plate 50 will continuously press the label, so as to keep it in a flat state and make the label pasting on the other side of the product more flat.

[0039] The labeling machine may further include a sensor 21 and a controller. The sensor 21 is electrically connected to the controller, and the sensor 21 may be a high-precision laser sensor 21. The sensor 21 is disposed on the elastic labeling plate 20 and can move along with the elastic labeling plate 20. The sensor 21 is used to detect whether the product has left the elastic labeling plate 20. When the sensor 21 detects that the product has left the elastic labeling plate 20, the elastic labeling plate 20 will reset, and the controller controls the tape conveying mechanism 30 to convey the next label to the position where the opening 113 is located, repeating the above actions.

[0040] The labeling machine further includes a first adjusting member 61. The pressing plate 50 is connected to the first adjusting member 61, and the first adjusting member 61 is used to adjust the position of the pressing plate 50. Specifically, the first adjusting member 61 includes a first adjusting unit 611 and a second adjusting unit 612. The first adjusting unit 611 is used to adjust the pressure of the pressing plate 50 on the label, and the second adjusting unit 612 is used to adjust the distance between the pressing plate 50 and the opening 113, so as to press labels of different thicknesses and sizes, with stronger applicability.

[0041] In this embodiment, the second adjusting unit 612 is connected to the pressing plate 50, and the second adjusting unit 612 is installed on the first adjusting unit 611.

[0042] The labeling machine further includes a second adjusting member 62. The peeling knife 40 is connected to the second adjusting member 62, and the second adjusting member 62 is used to adjust the position of the peeling knife 40 relative to the opening 113. When the label is small, the peeling knife 40 can be made closer to the opening 113, and when the label is large, the peeling knife 40 can be made farther away from the opening 113, so that it can be applicable to labels of different sizes.

[0043] The labeling machine further includes a pressing device 70. After the peeled part of the label is attached to the first surface of the product, the pressing device 70 is used to press the un-attached part of the label onto the second surface of the product when the product continues to move for labeling. After the peeled part of the label is attached to the first surface of the product, when the product continues to move, it will pull the label away from the tape 100 and will be pressed onto the second surface of the product by the pressing device 70.

[0044] In this embodiment, the pressing device 70 is an elastic pressing device, more preferably an elastic pressing roller. The elastic pressing device 70 protrudes from the operation surface 111, and the elastic pressing device 70 provides elastic pressure when the un-peeled part of the label is pressed onto the second surface of the product, so that the label is tightly attached to the second surface of the product.
