Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass bottle labeling technology, specifically a paper suction and pressing mechanism for glass bottle labeling. Background Technology
[0002] Labeling, or labeling, involves affixing labels to the surface of containers. Currently, self-adhesive labels are commonly used. Compared to traditional labels, self-adhesive labels offer advantages such as eliminating the need for glue, paste, and water, resulting in no pollution and saving time. They are widely applicable and convenient. Self-adhesive labels are a composite material made of paper, film, or other special materials as the face stock, coated with adhesive on the back, and with a silicone-coated release liner. After printing, die-cutting, and other processing, they become finished labels. Various types of self-adhesive labels can be used on materials where ordinary paper labels cannot be applied. In a sense, self-adhesive labels are versatile. The printing of self-adhesive labels differs significantly from traditional printing. Self-adhesive labels are typically printed and processed on label printing machines, completing multiple processes in one go, such as graphic printing, die-cutting, waste removal, sheet cutting, and rewinding. When labeling glass bottles, the entire label needs to be adhered to the placement plate on the conveyor. However, because the label is detached from its bottom support plate, the adhesion between the label and the placement plate is insufficient, and its thinness makes it prone to curling at the corners, affecting subsequent use. Therefore, operators considered sprinkling water on the conveyor, hoping the water's affinity would attract the label to the placement plate. However, the intensity and range of water spraying are uncontrollable, causing water droplets to condense on the label surface, preventing adhesion and affecting labeling quality. Furthermore, residual water entering the equipment can cause damage. Utility Model Content
[0003] The purpose of this invention is to overcome the problems mentioned in the background art and to provide a paper suction and pressing mechanism for labeling glass bottles. This mechanism can press the label firmly and keep it flat, and can also clean up condensed water droplets, so that the adsorption is not affected and the labeling quality is guaranteed.
[0004] The objective of this utility model is mainly achieved through the following technical solutions: The paper suction and pressing mechanism in glass bottle labeling includes a main support, with an installation mechanism below the main support. The installation mechanism houses both a paper suction mechanism and a paper pressing mechanism. The paper suction mechanism is capable of vertical movement, and the paper pressing mechanism is connected to a dripping device. Labels, also known as label sheets, are currently applied to glass bottles by first suctioning the entire label onto a placement plate on a conveyor. At this point, because the label detaches from its bottom support plate, it naturally curls. Furthermore, the suction contact point is in the center of the label, meaning the center contacts the support plate first, causing curling at the corners and preventing it from adhering properly to the placement plate. The label also cannot be fully unfolded, affecting subsequent use. Therefore, the operators thought of spraying water all over the conveyor table, using the affinity of water to adhere the labels to the placement plate, so that the labels could be fully unfolded. The labels themselves are waterproof and will not be softened by water. However, the intensity and range of water spraying cannot be controlled, and water droplets will enter the surface of the labels and form condensation, making it impossible to adhere the labels when applying them, affecting the labeling quality. Moreover, residual water entering the equipment will cause damage to the equipment. To address the aforementioned issues, this solution designs a paper suction and pressing mechanism for labeling glass bottles. The mechanism includes a main support connected to a gantry frame. As the gantry frame moves, the entire mechanism moves horizontally. An installation mechanism is located below the main support, housing both a paper suction mechanism and a paper pressing mechanism. The installation mechanism provides the mounting position and space for these mechanisms. The paper suction mechanism can move vertically, allowing for vertical distance changes—lifting or lowering the paper after suction. Combined with the gantry frame movement, this allows for label position changes. The paper pressing device presses the label onto a placement plate, ensuring complete label spread. Furthermore, a dripping device connected to the paper pressing mechanism drips water onto the placement plate before label placement, pressing the label firmly after placement. This process absorbs excess water, keeping the label flat and compact. It also removes condensed water droplets, ensuring uninterrupted suction, guaranteeing labeling quality, and ensuring equipment safety.
[0005] Furthermore, the mounting mechanism includes a slider and a mounting plate. The top of the slider is connected to the bottom of the main support and can move horizontally along the main support. The top of the mounting plate is fixed to the bottom of the slider. Both the paper suction mechanism and the paper pressing mechanism are connected to the mounting plate. The slider serves as an intermediate connecting component between the main support and the mounting plate, allowing the mounting plate to move with the main support. In the design, the slider is relatively small, while the mounting plate is relatively large, requiring sufficient length to connect with the paper suction mechanism and the paper pressing mechanism.
[0006] Furthermore, the paper suction mechanism includes a cylinder and a mounting plate fixed together. A suction cup mounting plate is positioned below the cylinder. The piston rod of the cylinder is fixed to the suction cup mounting plate. The extension and retraction of the piston rod causes the suction cup mounting plate to move vertically. Several parallel mounting rods are fixed to the bottom of the suction cup mounting plate, and suction cups are fixed to the bottom of each rod. By fixing the cylinder and mounting plate, and extending and retracting the piston rod of the cylinder to move the suction cup mounting plate vertically, the suctioned label paper also moves. Combined with the movement of the gantry frame, this causes a change in the paper's position. The suction cups are fixed to the bottom of the mounting rods and connected via air pipes, thus creating negative pressure suction. This is the existing structure.
[0007] Furthermore, the paper pressing mechanism includes a second cylinder, which is fixed to a mounting plate. A connecting frame is located below the second cylinder, and the piston rod of the second cylinder is fixed to the connecting frame. The extension and retraction of the piston rod drives the connecting frame to move vertically. A connecting shaft is installed in the connecting frame, with both ends connected to the connecting frame. A roller is fitted onto the connecting shaft, and the roller can rotate around its own axis. The vertical movement of the connecting frame caused by the piston rod of the second cylinder moves the connecting shaft, thus enabling vertical movement during the paper pressing process. An adsorption cylinder made of sponge is fitted onto the roller. The sponge absorbs water from the surface of the paper, resulting in more stable adsorption force when the label is applied under negative pressure.
[0008] Furthermore, elongated holes are provided on the connecting frame, and both ends of the connecting shaft are inserted into the corresponding elongated holes and can move vertically within the elongated holes. Through the elongated holes, the connecting shaft moves vertically within them, creating self-adaptive movement of the roller. During paper pressing, if the conveyor belt surface is uneven, it can adaptively adjust according to the surface undulations.
[0009] Furthermore, the dripping device includes a dripping mounting tube, which is fixed to a connecting bracket. The dripping mounting tube has several dripping holes. By connecting the water pipe to the dripping mounting tube, water is dripped onto the placement plate through the dripping holes, facilitating the placement and adhesion of the paper. The dripping method reduces water splashing and water volume, preventing incomplete absorption during subsequent water absorption.
[0010] Furthermore, both cylinder one and cylinder two have slide rails on their side walls, and sliding connecting plates are fitted onto these rails. These sliding connecting plates can slide vertically along the rails, and their bottoms are fixed to the corresponding suction cup mounting plates or connecting frames. This structure ensures the stability of the suction cup mounting plates or connecting frames when the cylinders move them, resulting in higher efficiency and quality during operation.
[0011] In summary, compared with the prior art, this utility model has the following advantages: The paper suction mechanism of this utility model can move vertically to achieve vertical distance changes, that is, it can lift or lower after suctioning the paper. With the gantry frame moving, the label position can be changed. The paper pressing device presses the label onto the placement plate to achieve complete label spreading. In addition, by connecting the paper pressing mechanism to the water dripping device, water is dripped onto the placement plate before placement. After the label is placed, it is pressed tightly, and excess water is absorbed, so that the label is pressed tightly and kept flat. Moreover, it can clean up the condensed water droplets, so that the suction is not affected, ensuring the labeling quality, and also ensuring the safety of the equipment. Attached Figure Description

[0017] like Figure 1 As shown, the paper suction and pressing mechanism in the glass bottle labeling of this embodiment includes a main support 6, which is connected to a gantry frame. As the gantry frame moves, the entire mechanism moves horizontally together. An installation mechanism is provided below the main support 6, on which a paper suction mechanism and a paper pressing mechanism are installed. The installation mechanism provides installation positions and space for the paper suction mechanism and the paper pressing mechanism. The paper suction mechanism can move vertically to achieve vertical distance changes, that is, it can lift or lower after suctioning the paper. Combined with the movement of the gantry frame, the label position can be changed. The paper pressing device presses the label onto the placement plate to achieve complete label spreading. A water dripping device is connected to the paper pressing mechanism to drip water onto the placement plate before placement. After the label is placed, it is pressed tightly, and excess water is absorbed, so that the label is pressed tightly and kept flat. It can also clean up the condensed water droplets, so that the suction is not affected, ensuring labeling quality and equipment safety.
[0018] The mounting mechanism includes a slider 4 and a mounting plate 3. The top of the slider 4 is connected to the bottom of the main support 6 and can move horizontally along the main support 6. The top of the mounting plate 3 is fixed to the bottom of the slider 4. The paper suction mechanism and the paper pressing mechanism are both connected to the mounting plate (3). The slider 4 serves as an intermediate component connecting the main support 6 and the mounting plate 3. It allows the mounting plate 3 to move with the main support 6. Moreover, the slider 4 is relatively small and the mounting plate 3 is relatively large in the design. The mounting plate 3 needs to be of sufficient length to connect with the paper suction mechanism and the paper pressing mechanism.
[0019] Two vertical plates, named Vertical Mounting Plate 1-2 and Vertical Mounting Plate 2-16, are fixed to both ends of the mounting plate 3. These plates serve as the positions for fixing the cylinders. The paper suction mechanism includes a cylinder 5, which is fixed to the vertical mounting plate 2. A suction cup mounting plate 8 is located below the cylinder 5. The piston rod of the cylinder 5 is fixed to the suction cup mounting plate 8. The piston rod extends and retracts, causing the suction cup mounting plate 8 to move vertically. Several parallel mounting rods 7 are fixed to the bottom of the suction cup mounting plate 8, and suction cups 9 are fixed to the bottom of each rod 7. By fixing the cylinder 2 and the vertical mounting plate 2, keeping the cylinder 2 stationary, the piston rod of the cylinder 2 extends and retracts, causing the suction cup mounting plate 8 to move vertically, thus moving the suctioned label paper. Combined with the movement of the gantry frame, this changes the position of the paper. The suction cups 9 are fixed to the bottom of the mounting rods 7 and connected to an air pipe, creating negative pressure suction. This is the existing structure. To accommodate the size of the label, multiple mounting rods 7 are provided, each with a suction cup 9 installed near the bottom of its end. This increases the suction area, making the adhesion tighter, while also allowing the paper to be spread out and stretched as much as possible.
[0020] The paper pressing mechanism includes a second cylinder 17, which is fixed to a second vertical mounting plate 16. A connecting frame 15 is located below the second cylinder 17. The piston rod of the second cylinder 17 is fixed to the connecting frame 15. The extension and retraction of the piston rod drives the connecting frame 15 to move vertically. The connecting frame 15 consists of a horizontal connecting plate and two vertical connecting plates 11. The vertical connecting plates 11 are fixed to the ends of the horizontal connecting plates. The piston rod of the second cylinder 17 is fixed to the horizontal connecting plates. The vertical connecting plates 11 have an L-shaped structure. A connecting shaft 14 is arranged between the vertical connecting plates 11. The two ends of the connecting shaft 14 are connected to the vertical connecting plates 11. Thus, the connecting shaft 14 is located below the connecting frame 15. A roller 13 is sleeved on the connecting shaft 14 and can rotate around its own axis. The piston rod of the second cylinder 17 drives the connecting frame 15 to move vertically, causing the connecting shaft 14 to also move, thereby enabling vertical movement during the paper pressing process. An adsorption cylinder 1, made of sponge, is fitted onto roller 13. The sponge absorbs water from the surface of the paper, resulting in more stable adsorption force when the label is applied under negative pressure. A cylinder 17 allows for convenient pressing down as needed.
[0021] The vertical connecting plate 11 is provided with elongated holes 19. The two ends of the connecting shaft 14 are respectively inserted into the corresponding elongated holes 19 and can move vertically in the elongated holes 19. By setting the elongated holes 19, the connecting shaft 14 can move vertically in the elongated holes 19, forming the self-adaptive function of the roller. When pressing paper, if the surface of the conveyor belt is uneven, it can adaptively adjust according to the undulation of the conveyor belt surface.
[0022] The drip device includes a drip mounting pipe 12, which is fixed to a vertical connecting plate 11. The drip mounting pipe 12 has several drip holes. The drip mounting pipe 12 and the connecting shaft 14 are arranged parallel to each other. Water is introduced into the drip mounting pipe 12 by connecting it to a water pipe, and the water drips onto the placement plate through the drip holes, facilitating paper placement and adhesion. The dripping method reduces water splashing and water volume, preventing incomplete absorption during subsequent water absorption. It can also be configured to pre-drip, used to pre-wet the labeling paper.
[0023] Both cylinder 5 and cylinder 17 have slide rails on their side walls, and sliding connecting plates are fitted onto these rails. These sliding connecting plates can slide vertically along the rails, and their bottoms are fixed to the corresponding suction cup mounting plate 8 or connecting frame 15. This system of slide rails and sliding connecting plates ensures the stability of the suction cup mounting plate or connecting frame when the cylinder moves it, resulting in higher efficiency and quality during operation.
[0024] In this system, the bracket mounting plate is first connected to the gantry frame. The water pipe is then connected to the drip installation pipe 12 and water is supplied. The piston rod of cylinder 5 moves downward, causing the suction cup mounting plate 8 to move downward. The suction cup 9 contacts the label to be absorbed, and after negative pressure adsorption, the piston rod moves upward, causing the label to rise. The gantry frame begins to move, and the roller 13 begins to move along the placement plate, using the suction cylinder 1 to absorb any remaining water. Simultaneously, new water begins to drip from the drip hole onto the placement plate. When the suction cup 9, carrying the label, reaches its position, the piston rod moves downward until the label contacts the placement plate, the negative pressure is released, and the label falls. On the placement plate, the water on the plate adheres to the label. The piston rod moves upward, the suction cup moves upward, the water pipe stops flowing, the gantry moves in the reverse direction, and the roller 13 begins to move in the reverse direction. Using its own weight, the label is pressed firmly onto the placement plate. During this process, excess water is squeezed onto the placement plate, and residual water dripping from the drip hole falls onto the label. Therefore, the suction cylinder 1 absorbs the residual water on the label and the excess water on the placement plate, ensuring the label is clean, preventing slippage during subsequent negative pressure suction, ensuring labeling quality, and also preventing water from being absorbed into the suction equipment, ensuring the safety of the equipment.
