Description

Technical Field

[0001] This utility model relates to the field of packaging machinery technology, and in particular to an active labeling device for a liquid container labeling machine. Background Technology

[0002] Labeling machines are an indispensable piece of equipment in the modern packaging industry. They are widely used in food, pharmaceutical, and daily chemical industries to affix labels to liquid containers. The flatness and firmness of the labels directly affect the appearance quality and market image of the products.

[0003] To ensure that the label can adhere well to the container surface, labeling machines are usually equipped with a label pressing device. In the existing technology, a common label pressing method is to use passive rollers to roll the label. The rotation of these rollers often depends on the movement of the container itself or the pulling force when the label is conveyed, and they do not have an active power source.

[0004] However, this passive rolling method has its shortcomings. Since the rotation speed and pressure of the rollers are completely controlled by the moving speed and contact friction of the container, when the production speed changes or the surface of the container is irregular, it is easy to cause uneven rolling pressure or a mismatch between the rolling speed and the labeling speed. This directly leads to the easy formation of air bubbles and wrinkles between the label and the container, or the label peeling off in subsequent stages due to poor adhesion, which seriously affects the product's pass rate and appearance.

[0005] Therefore, this utility model proposes an active labeling device for liquid container labeling machines to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of labeling devices for liquid containers in the prior art, such as weak label adhesion, easy generation of air bubbles and wrinkles, and unstable labeling quality due to the passive labeling method, this utility model aims to provide an active labeling device with an improved structure that can effectively solve the above problems.

[0007] This utility model provides an active labeling device for a liquid container labeling machine, comprising: a frame, a base plate, a sponge wheel, a wheel axle, a transmission assembly, and a fixing assembly.

[0008] The transmission assembly, used to achieve active marking, includes a motor, a drive shaft, a first bevel gear, a driven shaft, a second bevel gear, a second synchronous pulley, a first synchronous pulley, and a synchronous belt.

[0009] Furthermore, the aforementioned components are assembled in the following manner: the base plate is fixedly connected to the frame; the output end of the motor is connected to the input end of the drive shaft; the first bevel gear is fixedly connected to the output end of the drive shaft; the second bevel gear is fixedly connected to one end of the driven shaft and meshes with the first bevel gear; the driven shaft and the axis of the drive shaft intersect; the second synchronous pulley is fixedly connected to the driven shaft; the first synchronous pulley is fixedly connected to the axle; and the synchronous belt is fitted around the outer periphery of the first and second synchronous pulleys; the sponge wheel is fixedly connected to one end of the axle; and the fixing assembly is mounted on the base plate.

[0010] Preferably, the fixing component includes an electric push rod and a clamping plate. The electric push rod is fixed to the base plate, and its output end is connected to the clamping plate. This structure enables the clamping action of the liquid container to be completed automatically, improving production efficiency and positioning reliability.

[0011] Preferably, the device further includes a dustproof box and a connecting block. The dustproof box is fixedly connected to the frame via the connecting block and houses at least a portion of the transmission components. This design effectively protects the delicate internal transmission components from dust and external environmental interference, extending the service life of the equipment.

[0012] Preferably, the motor is fixedly connected to the frame or the dustproof box, providing a stable and reliable power source foundation for the entire device.

[0013] Preferably, in order to ensure efficient torque transmission, the first bevel gear is keyed to the drive shaft, and the second bevel gear is also keyed to the driven shaft.

[0014] Preferably, in order to ensure the accuracy of synchronous transmission, the first synchronous pulley is connected to the axle by a key, and the second synchronous pulley is also connected to the driven shaft by a key.

[0015] Preferably, in order to ensure smooth operation of all rotating components, the drive shaft is rotatably connected to the frame via bearings, the wheel axle is rotatably connected to the dustproof box via bearings, and the driven shaft is rotatably connected to the connecting block via bearings.

[0016] Preferably, the transmission structure of the device has a compact layout, specifically in that the wheel axle is set horizontally, the driven shaft is set vertically, and the driving shaft is also set horizontally, and the power is turned 90 degrees through the bevel gear set.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problem of label adhesion failure and air bubbles caused by passive rolling or uneven pressure in the prior art by setting a transmission component driven by a motor. The transmission component drives the sponge wheel to rotate actively through bevel gear steering and synchronous belt transmission. This achieves the technical effect of improving labeling quality and flatness.

[0018] 2. This utility model, by setting a fixing component consisting of an electric push rod and a clamping plate, automatically clamps and fixes the liquid container before labeling, solving the problem of possible displacement or shaking of the container during the labeling process, ensuring the accuracy of the sponge wheel rolling path, and achieving the technical effect of improving labeling accuracy and repeatability stability.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please refer to Figures 1 to 4This utility model provides an active labeling device for a liquid container labeling machine, which aims to solve the problem that the label does not adhere firmly to the container surface and is prone to air bubbles due to structural limitations in the existing labeling devices.

[0023] like Figure 1 As shown, the active labeling device includes a frame 1 and a base plate 7 fixedly connected to the frame 1. The device also includes a sponge wheel 5 for rolling the label, a transmission assembly 6 for driving the sponge wheel 5 to rotate, and a fixing assembly 8 for clamping the container. The transmission assembly 6 is installed on the frame 1, and the fixing assembly 8 is set on the base plate 7. Specifically, the sponge wheel 5 is connected to the transmission assembly 6 through a wheel axle 4. The transmission assembly 6 acts as a power mechanism to drive the sponge wheel 5 to rotate actively. When labeling liquid containers, the fixing assembly 8 clamps and fixes the container, and the rotating sponge wheel 5 rolls the label so that the label can be tightly and flatly attached to the surface of the container.

[0024] Reference Figure 1 , Figure 2 and Figure 3 The transmission assembly 6 is the core component for realizing the active rotation of the sponge wheel 5. The transmission assembly 6 includes a motor 601, a drive shaft 608, a first bevel gear 606, a driven shaft 604, a second bevel gear 607, a second synchronous pulley 605, a first synchronous pulley 602, and a synchronous belt 603. The motor 601 serves as the power source, and its output end is connected to the input end of the drive shaft 608. The output end of the drive shaft 608 is fixedly connected to the first synchronous pulley 602. The driven shaft 604 is arranged intersecting the axis of the drive shaft 608. One end of the drive shaft 608 is fixedly connected to a first bevel gear 606, and a second bevel gear 607 meshes with the first bevel gear 606, thereby transmitting the rotational motion of the drive shaft 608 to the driven shaft 604. A second synchronous pulley 605 is fixedly connected to the driven shaft 604, and a first synchronous pulley 602 is fixedly connected to the axle 4. A synchronous belt 603 is fitted around the outer periphery of the first synchronous pulley 602 and the second synchronous pulley 605. Through the transmission of the synchronous belt 603, the rotation of the driven shaft 604 is transmitted to the axle 4, ultimately driving the sponge wheel 5 to rotate actively.

[0025] To achieve stable and accurate active marking, this embodiment has specifically designed the structural layout of the transmission assembly 6 and related components. Please refer to the following for details. Figure 1 , Figure 3 and Figure 4 The core structure will be described in detail below: Reference Figure 3The drive shaft 608 is horizontally positioned, with its input end connected to the output end of the motor 601. The first bevel gear 606 is fixedly connected to the output end of the drive shaft 608 via a key connection. This structure ensures that the power generated by the motor 601 can be transmitted to the first bevel gear 606 without slippage. (Refer to...) Figure 2 The driven shaft 604 is vertically arranged. The second bevel gear 607 is fixedly connected to the driven shaft 604 by a key connection and meshes with the first bevel gear 606. Through the meshing transmission of this pair of bevel gears, the horizontal rotational motion of the drive shaft 608 is efficiently converted into the vertical rotational motion of the driven shaft 604.

[0026] At the same time, refer to Figure 1 The axle 4 is also horizontally positioned. The first synchronous pulley 602 is fixedly connected to the axle 4 via a key connection, and the second synchronous pulley 605 is fixedly connected to the driven shaft 604 via a key connection. The synchronous belt 603 is tightly fitted around the outer periphery of the first synchronous pulley 602 and the second synchronous pulley 605. This synchronous belt 603 transmission structure ensures that the rotation of the driven shaft 604 can be transmitted to the axle 4 proportionally and without delay, thereby driving the sponge wheel 5 to rotate stably. To protect and support the entire transmission assembly 6, the device is also equipped with a dustproof box 3 and a connecting... Block 2 and dustproof box 3 are fixedly connected to frame 1 via connecting block 2. At least some parts of transmission component 6 are housed in the dustproof box 3. This arrangement can effectively prevent dust and other impurities from entering the transmission system, ensuring transmission accuracy and service life. The drive shaft 608 is rotatably connected to frame 1 via bearing, the wheel axle 4 is rotatably connected to dustproof box 3 via bearing, the driven shaft 604 is rotatably connected to connecting block 2 via bearing, and the motor 601 is also fixedly connected to frame 1 or dustproof box 3, ensuring the smooth operation and positioning accuracy of all rotating parts.

[0027] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, to achieve automated clamping and positioning of liquid containers, please refer to... Figure 1 and Figure 4 The specific structure of the fixing component 8 has been further optimized. The fixing component 8 includes an electric push rod 801 and a clamping plate 802. The electric push rod 801 is fixed on the base plate 7, and its output end is connected to the clamping plate 802. By controlling the extension and retraction of the electric push rod 801, the clamping plate 802 can be driven to reciprocate in the horizontal direction, thereby realizing the rapid clamping and release of liquid containers of different sizes. This structure has a high degree of automation and accurate and reliable positioning.

[0028] The working principle of the active labeling device for a liquid container labeling machine of this utility model is as follows: When it is necessary to label a liquid container, the container is first placed on the base plate 7. Then, the electric push rod 801 in the fixing assembly 8 is activated, and its output end pushes the clamping plate 802 forward to stably clamp the liquid container in the predetermined position.

[0029] Next, the transmission assembly 6 starts working, the motor 601 starts and outputs rotational power, which is transmitted to the first bevel gear 606 through the drive shaft 608. Since the first bevel gear 606 meshes with the second bevel gear 607, the horizontal rotation of the drive shaft 608 is converted into the vertical rotation of the driven shaft 604. The second synchronous pulley 605, which is fixedly connected to the driven shaft 604, rotates accordingly, and drives the first synchronous pulley 602 and the wheel axle 4 fixed thereto to rotate through the synchronous belt 603, which finally drives the sponge wheel 5 at the end of the wheel axle 4 to rotate actively.

[0030] While the sponge wheel 5 rotates, the labeling machine's labeling mechanism delivers the label to the container surface. The actively rotating sponge wheel 5 rolls over the label surface, using its elasticity and active rotational force to press the label tightly and flatly onto the container. This effectively eliminates air between the label and the container, solving the problems of poor adhesion and air bubbles caused by uneven pressure or passive rolling, thereby improving labeling quality and efficiency.

[0031] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
