[0018] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. 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.

[0019] Please see Figure 1-4The present invention is a labeling mechanism for a compressor, comprising: a machine base 1, a lifting mechanism 2 disposed on the machine base, a label dispenser 3, a first propulsion cylinder 4 disposed on the lifting mechanism, and a labeling component 5 disposed on the telescopic end of the first propulsion cylinder. In this embodiment, the lifting mechanism is a lifting cylinder, used to drive the first propulsion cylinder to move to the label dispensing position of the labeling component, so as to facilitate the vacuum suction cup to peel the label from the release paper on the label dispenser. The first propulsion cylinder is used to push the label onto the surface of the compressor to be labeled. The labeling component is used to push the label open and press it tightly onto the surface of the compressor to be labeled, so as not to cause misalignment, wrinkles, edge lifting, or air bubbles.

[0020] Specifically, the labeling assembly includes a second propulsion cylinder 51 located at the telescopic end of the first propulsion cylinder, a base plate 52 located on the telescopic end of the second propulsion cylinder, a first swing arm 53 and a second swing arm 54 rotatably connected to the base plate at one end, a support plate 55 located at the other end of the first and second swing arms, and a tension spring 56 for assisting the first and second swing arms in resetting after being extended. The support plate is provided with a labeling roller 57 for rolling the label and a vacuum suction cup 58 for adsorbing the label. The vacuum suction cup has several suction holes for adsorbing the label, and the surface of the vacuum suction cup is in contact with the labeling roller. The surfaces are flush. After the labeling machine prints the label, the lifting mechanism drives the entire first propulsion cylinder to move to the label dispensing position. After the two sets of vacuum suction cups firmly adhere to the label, the lifting mechanism retracts and resets. The first propulsion cylinder pushes out the entire labeling assembly. The second propulsion cylinder starts to move and pushes the labeling assembly on the base plate closer to the compressor surface to be labeled. The first and second swing arms open under the action of the second propulsion cylinder and drive the two sets of labeling rollers to slowly smooth and cover the label on the suction cups onto the compressor surface. It is flat and wrinkle-free, and it is not easy to have wrinkles, edge lifting and air bubbles. The labeling effect is good.

[0021] Specifically, a first support seat 59 and a second support seat 50 are respectively provided on both sides of the first and second swing arms on the base plate. There are two sets of the first and second support seats and four sets of tension springs. One end of two sets of tension springs is connected to the first support seat and the other end is connected to the second swing arm. One end of the other two sets of tension springs is connected to the second support seat and the other end is connected to the first swing arm. The tension springs are staggered so that after labeling is completed, they can quickly help the two sets of swing arms to reset for the next labeling operation.

[0022] Preferably, a micro switch (not shown in the figure) is provided on the base plate to cooperate with the first or second swing arm. When the first or second swing arm contacts the micro switch, it can send a signal to the first and second propulsion cylinders. A side plate 6 is provided on the base plate, and a limit sensor 7 is provided on the side plate to sense the opening angle of the first and second swing arms and transmit a signal to the first and second propulsion cylinders to limit the opening angle of the first and second swing arms.

[0023] The beneficial effects of the labeling mechanism for a compressor of this utility model are: the second propulsion cylinder drives the first swing arm, and the second swing arm opens to drive the labeling roller to gradually smooth and cover the label onto the outer surface of the compressor. It is suitable for labeling products such as compressors with curved shapes, and will not cause misalignment, wrinkles, edge lifting or air bubbles, thus improving production efficiency.

[0024] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
