In addition, the terms "first", "second" and the like are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features limited by "first", "second" and the like can explicitly or implicitly include one or more features. In the description of the present utility model creation, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0013] In the description of the present utility model creation, it should be noted that, unless otherwise specified and limited, the terms "mounting", "connection", "connection", "fixed connection", "fixed connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or the communication between two elements. For ordinary skilled in the art, the specific meaning of the above terms in the present utility model creation can be understood through specific circumstances.

[0014] The specific implementation of the present utility model will be described in detail below with reference to the preferred embodiments.

[0015] AsFigure 1 As shown in the figure, an online labeling mechanism for hollow blow molding bottles comprises a material roll 1, a base plate 2 and a plurality of guide rollers 3, wherein the material roll and the plurality of guide rollers are respectively installed on the base plate, and an electrostatic elimination mechanism 4 is arranged on the base plate. Figure 2 As shown in the figure, the electrostatic elimination mechanism comprises a metal transmission roller 41, a label transmission roller 42, an upper connecting plate 43, a left connecting plate 44, a right connecting plate 45, an upper connecting arm 46, a lower connecting arm 47, a hinge shaft 48, a pressing plate 49 and an adjusting nut 40, wherein the upper portions of the left connecting plate and the right connecting plate are respectively fixed to the upper connecting plate, and in the device, the upper connecting plate, the left connecting plate and the right connecting plate wrap the upper connecting arm, the lower connecting arm, the hinge shaft and the pressing plate inside. The lower portions of the left connecting plate and the right connecting plate are fixed to the base plate, the upper and lower ends of the label transmission roller are respectively connected to the upper connecting plate and the base plate through bearings, the label transmission roller is a structure in the prior art and mainly serves to transmit labels, the two ends of the hinge shaft are respectively connected to the upper connecting plate and the base plate, one end of the upper connecting arm and one end of the lower connecting arm are respectively hinged to the upper portion and the lower portion of the hinge shaft, and the other end of the upper connecting arm and the other end of the lower connecting arm are respectively hinged to the metal transmission roller. Since the metal transmission roller is in contact with the surface of the label, the static electricity on the upper portion of the label is transmitted to the upper and lower connecting arms through the metal transmission roller, and then is transmitted to the hinge shaft through the upper and lower connecting arms.

[0016] The pressing plate is fixed between the upper connecting arm and the lower connecting arm, the adjusting nut is threadedly connected to the left connecting plate and cooperates with the side portion of the pressing plate, and the lower end of the hinge shaft is grounded through a wire. When the adjusting nut is tightened, the front end of the adjusting nut will press the pressing plate, and the upper and lower ends of the pressing plate will drive the upper connecting arm and the lower connecting arm to rotate around the hinge shaft, thereby driving the metal transmission roller on one side to press the label on the label transmission roller, and further guiding the static electricity on the label to the metal transmission roller.

[0017] Of course, in order to be more convenient, an anti-static rope can also be used to replace the structure, and the anti-static rope is arranged at the label roller and is connected to the machine to achieve grounding. The static electricity generated by the friction between the label and the roller during the movement of the roller is eliminated through the metal wire inside the anti-static rope. Although the purpose of eliminating static electricity can also be achieved, the disadvantage is that the anti-static rope is easy to be wound into the guide roller. The electrostatic elimination mechanism is separately arranged on the base plate, the metal transmission roller, the upper connecting arm, the lower connecting arm, the hinge shaft and the pressing plate are metal structures, the static electricity is transmitted to the hinge shaft through the metal transmission roller, the pressing plate, the upper connecting arm and the lower connecting arm, the bottom of the hinge shaft is grounded through a wire, the overall layout is reasonable, and no interference is generated to the existing equipment.

[0018] Further, in order to adjust the tightness of the label, an adjusting cylinder 5 is arranged on the base plate, and a piston rod of the adjusting cylinder is connected to an adjusting plate 6. The plurality of guide rollers are arranged in a curve on the base plate.

[0019] As a further improvement of the utility model, at least two glue outlets are arranged on the glue roller of the labeling machine (as the improvement of the existing structure, the specific position is not marked, only one glue outlet is added in the existing structure). In the labeling process, the end needs to be connected by using glue. In the past, only one glue outlet was provided on the machine. However, when the ambient temperature decreases in winter, the bottle will shrink due to thermal expansion and contraction, causing the label to be relatively larger, which is easy to collapse or fall off. Therefore, 1-2 additional glue outlets are provided to make the product more easily connected and fixed, so as to ensure the stability of the labeling process at any time throughout the year.

[0020] It should be pointed out that for ordinary skilled persons in the art, without departing from the principles of the utility model, a number of improvements and refinements can be made, and these improvements and refinements should also be considered as the protection scope of the utility model.
