Description

Technical Field

[0001] This utility model belongs to the field of label static elimination technology, specifically relating to a label roll static elimination device. Background Technology

[0002] During the production, processing, and transportation of label rolls, the continuous friction, contact separation, and squeezing between the label material (especially thin-film insulating materials) and equipment components such as unwinding rollers, pressure rollers, and guide rollers easily generate and accumulate a large amount of static charge. This type of static electricity problem is significantly affected by environmental humidity, and is particularly prominent in the dry autumn and winter seasons, persisting throughout the entire process from unwinding and processing to rewinding.

[0003] Existing label roll static eliminators mostly employ single structures such as ionizing air bars, conductive brushes, or static eliminator rollers, which have significant limitations: some devices can only eliminate static electricity at fixed locations, making it difficult to adapt to the static electricity generation characteristics of multiple friction points during label transport, especially in high-speed unwinding and rewinding scenarios where the elimination effect is poor; some devices lack real-time static electricity detection capabilities, making it impossible to accurately judge the static eliminator effect and to dynamically adjust the detection and elimination points according to changes in label width or position; in addition, existing equipment often neglects the tension stability and limit guidance during label transport, and label misalignment or uneven tension will further aggravate frictional static electricity generation, leading to secondary static electricity accumulation and affecting the final static eliminator quality.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0029] See Figure 1 and Figure 2 This is a structural diagram of a label roll antistatic device in this embodiment. The label roll antistatic device uses a bracket 100 as the overall support frame to support the various functional components of the device and ensure the structural stability of the label roll during conveying, antistatic removal, and rewinding. A unwinding roller 108 is rotatably connected to the bracket 100 via bearings. The unwinding roller 108 is used to hold the original label roll to be antistatic removed. Its rotatable connection method can adapt to the dynamic tension changes during the unwinding process of the label roll, avoiding stretching deformation of the label roll due to excessive unwinding resistance. A conductive rubber plate 107 is provided on the side opposite to the unwinding roller 108. The conductive rubber plate 107 is made of rubber material with high conductivity and can guide and release the static charge on the surface of the label roll through surface contact. To achieve stable support for the conductive rubber plate 107, a support plate 1071 is fixedly connected below it. The support plate 1071 is welded and fixed to the bracket 100 to ensure that the conductive rubber plate 107 does not shift during the conveying of the label roll.

[0030] See Figure 7 and Figure 8To achieve real-time monitoring of static electricity on the label roll surface, a waist hole 1072 is provided on the conductive adhesive plate 107. The waist hole 1072 is centered along the width direction of the conductive adhesive plate 107, and its length is adapted to the common width of label rolls, covering the detection needs of most label roll specifications. An electrostatic sensor 106 is installed on the lower surface of the conductive adhesive plate 107. The sensing area of ​​the electrostatic sensor 106 passes through the waist hole 1072 and is flush with the upper surface of the conductive adhesive plate 107. This ensures that the sensing area can directly contact the lower surface of the label roll for accurate detection of static electricity values, while also preventing the protruding sensing area from obstructing the label roll transport. The lower end of the plate is fixedly connected to a slide plate 1061 by bolts. The lower surface of the slide plate 1061 is slidably connected to a slide table 1062 via a slide rail. The slide table 1062 is fixedly connected to the support plate 1071. At the same time, a cylinder 1063 is mounted on the side of the slide plate 1061 away from the electrostatic sensor 106 via a cylinder seat. The piston rod of the cylinder 1063 is fixedly connected to the slide plate 1061. When the width of the label roll changes, the cylinder 1063 can drive the slide plate 1061 to slide along the slide table 1062, thereby adjusting the position of the electrostatic sensor 106 in the waist hole 1072, ensuring that the sensing area always corresponds to the effective area of ​​the label roll, and improving the detection accuracy.

[0031] See Figure 3 and Figure 6 On one side of the conductive adhesive plate 107, a limiting plate 105 is fixedly installed on the bracket 100. The limiting plate 105 is used to guide the label roll conveying direction and prevent the label roll from shifting laterally during conveying. On the upper surface of the limiting plate 105 near the conductive adhesive plate 107, a rotating roller 1053 is rotatably connected via a rotating shaft. The axis of the rotating roller 1053 is perpendicular to the label roll conveying direction, and its outer surface is covered with wear-resistant rubber to reduce frictional damage to the label roll surface. At the same time, directly above the rotating roller 1053, a pressure plate 1052 is bolted to the limiting plate 105. The distance between the lower end of the pressure plate 1052 and the outer surface of the rotating roller 1053 can be adjusted by bolts to accommodate label rolls of different thicknesses. To ensure smooth transport of the label roll between the roller 1053 and the pressure plate 1052 and further limit lateral deviation, a groove is provided on the other side of the upper surface of the limiting plate 105 along its width direction. A baffle 1051 is slidably connected in the groove by a slider. The baffle 1051 can slide along the groove and be fixed by a set bolt. By adjusting the distance between the two baffles 1051, it can accommodate label rolls of different widths and achieve precise positioning. In addition, a vertical plate is vertically fixed on one side of the lower surface of the limiting plate 105. A guide roller 1054 is rotatably connected to the vertical plate by a bearing. The guide roller 1054 is used to change the transport direction of the label roll. Its outer surface is polished to reduce the coefficient of friction with the label roll and avoid scratches on the surface of the label roll.

[0032] See Figure 3 and Figure 5A support plate 104 is horizontally fixedly installed on the bracket 100 and on one side of the limiting plate 105. A conductive blanket is laid on the upper surface of the support plate 104, and the conductive blanket is connected to a grounding device via a wire. This further adsorbs residual static charge on the label roll surface, achieving secondary static elimination. Hanging plates 1041 are rotatably connected to both sides of the support plate 104 via pins. A pressure roller 1044 is rotatably connected to the lower end of the hanging plate 1041 via a bearing. The axis of the pressure roller 1044 is perpendicular to the label roll conveying direction, and its outer surface is covered with elastic rubber to press the label roll. At the same time, it avoids damaging the surface; the hanging plate 1041 is located above the pressure roller 1044 and has an integrally formed connecting plate 1043. A spring 1042 is welded to the upper surface of the connecting plate 1043. The upper end of the spring 1042 abuts against the lower surface of the pallet 104. By utilizing the elastic force of the spring 1042, the pressure roller 1044 can always maintain the pressure on the label roll, and can adaptively adjust according to the change of the label roll thickness, ensuring that the label roll is transported smoothly on the pallet 104. At the same time, it enhances the contact effect between the conductive blanket and the label roll and improves the static elimination efficiency.

[0033] See Figure 3 and Figure 4 Directly below the guide roller 1054, a drive roller 102 is mounted on the bracket 100, providing power for the label roll conveying. One end of the drive roller 102 is connected to a flat plate via a bearing sleeve, and the flat plate is fixedly connected to the bracket 100 to support one end of the drive roller 102. The other end of the drive roller 102 passes through the rear surface of the bracket 100 and is fixedly sleeved with a first pulley 1021 via a key connection. The first pulley 1021 adopts a multi-groove structure design, which can realize power transmission and distribution simultaneously. A first belt 1011 is sleeved in one groove of the first pulley 1021, and the other end of the first belt 1011 is sleeved on the output shaft of the driver 101. The driver 101 is a servo motor, which is fixed to the rear surface of the bracket 100 by bolts. The servo motor can precisely control the rotation speed, thereby adjusting the conveying speed of the label roll to adapt to different processing requirements.

[0034] A second belt 1032 is fitted into the other groove of the first pulley 1021. The other end of the second belt 1032 is fitted with a second pulley 1031. The second pulley 1031 is fixedly fitted to one end of the take-up roller 103 by a key connection. The other end of the take-up roller 103 is rotatably connected to the front surface of the bracket 100 by a bearing. It is used to take up the label roll after the anti-static treatment. Through the transmission cooperation between the first pulley 1021 and the second pulley 1031, the rotation speed of the take-up roller 103 can be matched with the rotation speed of the drive roller 102, so as to avoid the label roll being too loose or too tight during the winding process and ensure the winding quality.

[0035] In addition, on the front surface of the bracket 100, and located between the take-up roller 103 and the drive roller 102, an antistatic roller 109 is rotatably connected via a bearing seat. The antistatic roller 109 is a rubber roller with built-in conductive fibers and is grounded via a wire. It can perform a third antistatic treatment before the label roll enters the take-up roller 103, further reducing static electricity residue. At the same time, on the front surface of the bracket 100, and located between the pallet 104 and the unwind roller 108, a tension roller is rotatably connected via a bearing seat. The tension roller can adjust the tension during the label roll conveying process to prevent the label roll from wrinkling due to uneven tension, ensuring the stable operation of subsequent antistatic and take-up processes.

[0036] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions.
