[0002] Labeling machines are devices that affix rolls of self-adhesive labels (paper or metal foil) to PCBs, products, or prescribed packaging. Labeling machines are an indispensable part of modern packaging, and well-designed labels can also help enhance a company's image and boost product sales. Previously, product labeling was done manually, which was slow and inefficient. Currently, the variety of labeling machines produced in my country is gradually increasing, and the technological level has greatly improved. The industry has shifted from the outdated manual and semi-automatic labeling methods to a situation where automated, high-speed labeling machines dominate the market.
[0003] Existing labeling machines cannot effectively inspect the labels to be applied and remove substandard labels, resulting in a low yield rate of finished products and making them unsuitable for industrial applications.
[0004] Therefore, it is necessary to propose a technical means to solve the above-mentioned defects. Utility Model Content

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0020] Please see Figures 1 to 3 A labeling device with a function of removing defective labels includes an unwinding shaft 10 for unwinding a label roll 30, a winding shaft 20 for winding the label roll 30, a labeling head 40 for receiving the label roll 30 output from the unwinding shaft 10 and applying labels, a detection mechanism 50 disposed between the unwinding shaft 10 and the labeling head 40 and arranged sequentially along the forward direction of the label roll 30 for detecting labels in the label roll 30, and a peeling mechanism 60 for peeling off defective labels from the label roll 30 after the detection mechanism 50 detects them.
[0021] The labeling device with the function of removing defective labels involved in this utility model, through the unwinding shaft 10, the rewinding shaft 20, the labeling head 40, the detection mechanism 50 and the peeling mechanism 60, can efficiently remove defective labels when completing the labeling process without manual assistance, thereby ensuring the accuracy of labeling.
[0022] In one specific embodiment, the detection mechanism 50 includes a CCD camera 501 for visually inspecting the labels within the label roll 30. Specifically, the CCD camera 501 enables efficient identification of the quality of the labels within the label roll 30.
[0023] In one specific embodiment, the peeling mechanism 60 includes a square peeling post 601 and a drive unit for driving the square peeling post 601 to rotate along the forward direction of the label roll 30; in the working state, the label roll 30 is in contact with the two adjacent sides of the square peeling post 601.
[0024] Specifically, in this embodiment, the label roll 30 is unwound by the unwinding shaft 10 and sequentially adheres to the two adjacent sides of the square peeling post 601 on the forward path, thereby forming a peeling angle for peeling off the label at that location.
[0025] When the inspection agency 50 detects that the label is defective, the drive unit does not work, so that the label roll 30 continues to move. The label is successfully removed from the label roll 30 at this point. It should be noted that during the movement of the label roll 30, the side with the label is the outer side of the label roll 30, and the side that is in contact with the square peeling post 601 is the inner side of the label roll 30.
[0026] When the testing agency 50 detects that the label is a good product, when the label roll 30 passes through the peeling angle, the driving unit drives the square peeling column 601 to rotate. The speed and direction of the rotation are the same as the speed and direction of the forward movement of the label roll 30, so that the label can pass through smoothly without falling out of the label roll 30.
[0027] In summary, this embodiment, with the square peeling post 601 and the driving unit, can efficiently peel off substandard labels, making it suitable for industrial applications.
[0028] In one specific embodiment, the driving unit includes a drive motor 602 adjacent to the square stripping post 601, used to drive the square stripping post 601 to rotate. Specifically, in this embodiment, the output end of the drive motor 602 is provided with a first transmission wheel 603, the bottom of the square stripping post 601 is provided with a second transmission wheel 604, and the first transmission wheel 603 and the second transmission wheel 604 are synchronously connected by a belt 605. During operation, the drive motor 602 drives the first transmission wheel 603 to rotate, which in turn drives the second transmission wheel 604 to rotate through the belt 605, thereby driving the square stripping post 601 to rotate.
[0029] In one specific embodiment, the square peeling post 601 is provided with guide rollers 606 on both sides for guiding the label roll 30 to wind around the adjacent sides of the square peeling post 601. Specifically, during operation, the two sides of the square peeling post 601 that are in contact with the label roll 30 are the adjacent first side and the second side; the guide rollers 606 are respectively provided on one side of the first side and the second side for guiding the label roll 30 to wind around the square peeling post 601.
[0030] In one specific embodiment, a receiving bin 607 for receiving the removed defective labels is also provided on one side of the square peeling column 601. Specifically, the receiving bin 607 has an inlet facing the direction in which the label roll 30 falls when the defective labels are peeled off, and the receiving bin 607 is inclined as a whole for better collection of defective labels.
[0031] In one specific embodiment, a printing mechanism 70 is also included, which is installed between the unwinding shaft 10 and the detection mechanism 50 along the forward direction of the label roll 30, for printing labels within the label roll 30.
[0032] The labeling device with the function of removing defective labels involved in this utility model, through the unwinding shaft 10, the rewinding shaft 20, the labeling head 40, the detection mechanism 50 and the peeling mechanism 60, can efficiently remove defective labels when completing the labeling process without manual assistance, thereby ensuring the accuracy of labeling.
[0033] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
