[0022] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as limiting the present utility model.

[0023] The following will further describe the present utility model in detail through specific implementation manners in combination with the attached Figure 1-7 For a further detailed description of the present utility model.

[0024] The present utility model provides a labeling machine, which includes a frame 1, a product feeding mechanism respectively installed on the frame 1 for feeding products to be labeled, a label feeding mechanism for feeding labels, a label peeling mechanism for separating the labels on the label feeding mechanism from the film, a labeling mechanism for grasping the labels separated from the film by the label peeling mechanism and pasting them onto the products on the product feeding mechanism, and a vision recognition mechanism for detecting whether the labels are abnormal and identifying the labeling positions on the products; the vision recognition mechanism includes a first recognition component for identifying whether the labels are abnormal and a second recognition component for identifying the labeling positions on the products.

[0025] In this embodiment, through the first recognition component, it is recognized whether the labels peeled from the film by the label peeling mechanism are abnormal, so as to prevent abnormal labels from being pasted onto the products, thereby avoiding the generation of defective labeled products. And through the second recognition component, the correct labeling positions on the products can be recognized, so as to accurately paste the labels onto the products. Through the settings of the first recognition component and the second recognition component, the labeling efficiency and the labeling yield are greatly improved.

[0026] In a specific embodiment, the label feeding mechanism includes a unwinding wheel 31 installed on the frame 1 for placing a label roll, a first auxiliary wheel 32 arranged at an interval from the unwinding wheel 31, a film pulling assembly arranged on the frame 1, and a film winding wheel 34 arranged on the frame 1. In this embodiment, the wound label roll is placed on the unwinding wheel 31, and the label film is pulled so that the label film bypasses the first auxiliary wheel 32 and the film pulling assembly respectively, and then the film after the label has been separated by the label stripping mechanism is wound by the film winding wheel 34, thereby completing the label feeding and film winding processes. Specifically, the film pulling assembly and the film winding wheel 34 are located below the unwinding wheel 31 and the first auxiliary wheel 32, so that the label film with labels and the label film after the labels are separated are layered into two layers, facilitating the feeding and collecting of the label roll.

[0027] In a specific embodiment, the label stripping mechanism includes a receiving platform 41 arranged on the frame 1, a label stripping knife 42 connected to one end of the receiving platform 41 away from the unwinding wheel 31, and a label receiving platform 43 arranged adjacent to the label stripping knife 42. A passing gap 44 for the film for pasting labels to pass through is formed between the label receiving platform 43 and the label stripping knife 42. One end of the label stripping knife 42 away from the receiving platform 41 has a height difference from the label receiving platform 43, and the label receiving platform 43 is higher than the end of the label stripping knife 42 away from the receiving platform 41. In this embodiment, during specific label stripping, the label film for pasting labels is connected to the film pulling assembly and the film winding wheel 34 through the passing gap 44, that is, the label film passes through the unwinding wheel 31, the first auxiliary wheel 32, the receiving platform 41, the passing gap 44, and the film pulling assembly in sequence. When passing through the passing gap 44, due to the height difference between the label stripping knife 42 and the receiving platform 41, and the receiving platform 41 is slightly higher than the label stripping knife 42, the side wall of the label (the label is pasted on the label film and the side wall of the label protrudes from the label film) can abut against the side wall of the receiving platform 41. Under the action of inertia, the label will be separated from the label film and move onto the receiving platform 41, while the label film continues to pass through the passing gap 44 and is wound by the film winding wheel 34.

[0028] In a specific embodiment, the label stripping knife 42 is rotatably connected to the receiving platform 41, so that the height difference between the label stripping knife 42 and the receiving platform 41 can be adjusted, enabling the labeling machine to be applicable to labels of different specifications.

[0029] In a specific embodiment, a plurality of adsorption holes 411 are arranged on the receiving platform 41, and the plurality of adsorption holes 411 are connected to an air extractor, so that the label film can be kept in contact with the plane where the receiving platform 41 is located during movement, thereby ensuring that the label can be separated from the label film when passing through the passing gap 44.

[0030] In a specific embodiment, the label feeding mechanism further includes a rotating power member 35 for driving the film collecting wheel 34 to rotate, and the rotating power member 35 is connected to the film collecting wheel 34 through a belt.

[0031] In a specific embodiment, a limiting member 45 is provided on the label peeling knife 42, and a passage 46 is provided between the limiting member 45 and the label peeling knife 42 for the labels that have not been separated from the film to pass through. The passage 46 is provided so that the label film can be limited on the label peeling knife 42, further ensuring that the label can be separated from the label film when passing through the gap 44.

[0032] In a specific embodiment, there are two first auxiliary wheels 32 , and the two first auxiliary wheels 32 have a height difference.

[0033] In a specific embodiment, the film pulling assembly includes a clamping frame 331 arranged at the lower end of the first auxiliary wheel, a driving wheel 332 axially connected to the clamping frame 331 and a film pressing group arranged on the clamping frame; the film pressing group includes a mounting strip 333 arranged on the clamping frame 331, a buffer member 334 connected to the mounting strip 333 through an elastic member 335, a clamping plate 336 rotatably connected to the arc groove 3311 on the clamping frame 331, and a lever 337 connected to the clamping plate 336; the clamping plate 336 is provided with an elastic wheel 339 abutting against the buffer member 334. In this embodiment, the label film passes through the gap 44 and passes through the gap between the driving wheel 332 and the clamping wheel 338, and is wound around the film collecting wheel 34. After that, the user can adjust the clamping plate 336 by the lever 337 The position of 36 in the arc groove 3311 is adjusted, thereby adjusting the clamping plate 336 to drive the mounting strip 333 to push the clamping wheel 338 to clamp the product in the gap between the tension wheel 338 and the driving wheel 332, so that when the driving wheel 332 rotates, it cooperates with the clamping wheel 338 to pull the label film to move, and the tension wheel 339 will elastically abut against the buffer member 334 under the elastic force of the elastic member 335, so that the clamping plate 336 can tighten the label film, thereby preventing the label film from not maintaining a tightened state during the movement, thereby affecting the normal operation of the label peeling process. Specifically, the driving wheel 32 can rotate the driving wheel through the transmission action of the driving motor and the belt. In some embodiments, the driving motor can be a rotating power member 35, that is, the driving motor can simultaneously drive the film collecting wheel 34 and the driving wheel 32 to rotate synchronously through the belt.

Then, the lateral driving assembly continues to drive the suction member 54 to move to the labeling position of the product feeding mechanism, and the longitudinal driving assembly drives the suction member 54 to drive the label to press down, so that the adhesive surface of the label contacts the labeling position of the product, thereby attaching the label to the product.
