Description
Technical Field
[0001] This utility model relates to the field of label application technology, and in particular to an automatic label application device. Background Technology
[0002] In modern industrial production, automatic labeling technology has been widely used in many fields such as food, medicine, and electronics. However, traditional labeling devices have exposed significant technical bottlenecks when faced with increasingly diverse label and product specifications, and urgently need innovative breakthroughs. Traditional label attaching devices often employ a fixed label transport path design. When producing labels of different sizes, the equipment cannot adjust the relative position and angle between the label and the item. For example, when processing narrow labels, the fixed transport path can easily cause the label to shift, resulting in excessive attachment position errors that severely affect the product's appearance. When dealing with irregularly shaped items, the fixed transport path makes it impossible to achieve precise label attachment, making the equipment extremely unsuitable for diverse production scenarios. Therefore, these problems need to be addressed. Utility Model Content

An attaching component is provided at the bottom of the fixed plate. The receiving roller 7 facilitates timely winding of the label backing paper, avoiding the accumulation of backing paper from affecting the label transmission and attaching process, and maintaining the cleanliness and orderliness of the label transmission system.
[0015] In this utility model, the attaching component includes an extension plate 11 fixed to the bottom of a fixed plate and a connecting post fixed to a clamping plate. A labeling plate 13 is bolted to the connecting post. The labeling plate 13 is semi-arc-shaped, and one side of the labeling plate 13 is coated with modified acrylic pressure-sensitive adhesive. A connecting plate 12 is provided at the bottom of the extension plate 11, and a slider is fixed to one side of the top of the connecting plate 12. An arc-shaped groove is opened at the bottom of the extension plate 11, and the connecting plate 12 slides in the arc-shaped groove through the slider. A baffle for peeling off the label is bolted to one end of the connecting plate 12. The attaching component facilitates the use of the adhesive properties of the pressure-sensitive adhesive to quickly and firmly attach the label to the item, realizing automated attaching operation. A mounting plate is provided on one side of the extension plate 11, and a sliding groove is opened at one end of the mounting plate. A limiting bolt for fixing the extension plate 11 and the mounting plate is inserted into the sliding groove. A smoothing roller 10 for smoothing the label on the item is rotatably provided at the other end of the mounting plate. 10. This design significantly improves the flatness and firmness of label application, enhances application quality, and improves the aesthetics and durability of the labels. A first motor is installed on one side of the fixed plate, and the output end of the first motor extends to the other side of the fixed plate where a second pulley is fixedly connected. One end of the feeding roller 3 is fixedly connected to the first pulley, and a transmission belt is sleeved between the first pulley and the second pulley. Multiple support plates are movably installed on one side of the fixed plate, and tension rollers 9 are fixedly connected to the support plates. A return spring 8 is provided at one end of the support plate and the fixed plate. The return spring 8 helps to keep the label in a suitable tension state during transmission, avoiding excessive looseness or tightness of the label. The adjustment component includes an adjustment cylinder 6 rotatably connected to the middle of one side of the fixed plate via a bearing. Multiple adjustment rollers are fixedly connected to the side wall of the adjustment cylinder 6, and a rotating handle is fixedly connected to the top of the adjustment cylinder 6. The adjustment component allows for flexible changes in the transmission angle and tightness of the label, enabling the label to be accurately and flatly applied to the surface of the item.
[0016] Working Principle: When using this utility model, firstly, connect each electrical component in this application to the power source. Then, after the motor inside the motor housing 5 starts, it outputs power to drive the belt conveyor 2. The belt conveyor 2 transports the items to be labeled on the workbench 1 at a constant speed, providing a stable basis for the subsequent labeling process. The items pass through the labeling area below the mounting frame 4 at a uniform speed along the set path, creating conditions for precise label-to-item adhesion. Next, the label roll wound on the unloading roller 3 starts to rotate under the drive of the motor. The second pulley fixed to the output end of the motor drives the first pulley at one end of the unloading roller 3 to rotate through the belt, realizing the automatic release of the label. The released label passes through multiple tension rollers 9. The tension rollers 9 work together with the support plate and the return spring 8. According to the tension change during the label transmission process, the position of the tension rollers 9 is automatically adjusted by the extension and retraction of the return spring 8 to ensure that the label always maintains appropriate tension and avoids excessive slack or tightness. At the same time, rotating the rotating handle on the adjusting cylinder 6 changes the angle of the adjusting roller on the side wall of the adjusting cylinder 6, which can finely adjust the label transmission path to adapt to different specifications. For label and item attachment, used label backing paper is recycled and wound by the take-up roller 7, rotating synchronously with the unloading roller 3 to maintain the orderly operation of the label conveying system. Then, when the label is conveyed to the attachment component, the labeling plate 13 plays a crucial role. The labeling plate 13 is semi-circular in shape, with a modified acrylic pressure-sensitive adhesive coated on one side to adsorb the label. At the same time, a baffle at one end of the connecting plate 12 peels the label off the backing paper. The connecting plate 12 slides in the arc-shaped groove at the bottom of the extension plate 11 via a slider, allowing the labeling plate to be flexibly adjusted according to the height of the item and the attachment position requirements. After the position and angle of label plate 13 are adjusted, the extension plate 11 is fixed to the mounting plate by the limit bolt to ensure the stability of label plate 13. When the item to be labeled passes under label plate 13 with the belt conveyor 2, the label is quickly and firmly attached to the surface of the item under the action of pressure-sensitive adhesive. Finally, after the label is attached to the item, it continues to move forward to the position of smoothing roller 10. Smoothing roller 10 rotates around the mounting plate to roll and squeeze the label surface, eliminate air bubbles between the label and the item, smooth wrinkles, and make the label and the item fit tightly. At this point, the use of the automatic label attaching device is over.
[0017] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
