[0036] Combine the following Figure 1 to Figure 5The technical solution provided by the utility model is described in more detail. The description of the exemplary embodiments is merely illustrative and is by no means intended to limit the present disclosure and its application or use. The present disclosure can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to make the present disclosure thorough and complete and to fully express the scope of the present disclosure to those skilled in the art. It should be noted that unless otherwise specifically stated, the relative arrangement of the components and steps, the composition of the materials, the numerical expressions and the numerical values ​​described in these embodiments should be interpreted as exemplary and not as limiting.

[0037] The words "first", "second" and similar words used in this disclosure do not indicate any order, quantity or importance, but are only used to distinguish different parts. The words "include" or "comprise" and similar words mean that the elements before the word include the elements listed after the word, and do not exclude the possibility of also including other elements.

[0038] In the present disclosure, when a specific device is described as being located between a first device and a second device, there may or may not be an intermediate device between the specific device and the first device or the second device. When a specific device is described as being connected to other devices, the specific device may be directly connected to the other devices without an intermediate device, or may not be directly connected to the other devices but have an intermediate device.

[0039] All terms used in the present disclosure, including technical terms or scientific terms, have the same meanings as those understood by ordinary technicians in the field to which the present disclosure belongs, unless otherwise specifically defined. It should also be understood that terms defined in general dictionaries, such as general dictionaries, should be interpreted as having meanings consistent with their meanings in the context of the relevant technology, and should not be interpreted in an idealized or extremely formal sense, unless explicitly defined herein.

[0040] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment are considered part of the specification.

[0041] The dimensions of the various parts shown in the drawings are not drawn according to the actual proportional relationship. In the drawings, the same reference numerals are attached to common structural elements or structural elements of the same type, and their repeated descriptions are appropriately omitted.

[0042] In the description of the specific embodiments below, for the convenience of explanation, Figure 5 The figure shows the rotation direction S1 of the turntable 2, the rotation direction S2 of the label suction drum 4, and the rotation direction S3 of the bracket 3. The container referred to herein is selected from one of the following: a bottle and a barrel. The bottle can be a mineral water bottle or a purified water bottle. The barrel can be a barrel of a water dispenser with a volume of about 20L.

[0043] The embodiment of the utility model provides a labeling machine, including the label adsorption device provided by any technical solution of the utility model. The labeling machine is used for attaching labels, which are also called labels.

[0044] In some embodiments, the labeling machine further includes a brush plate (not shown), and the adsorption plate 1 is installed at the front end of the brush plate. The adsorption plate 1 is located between the label and the brush plate, and can provide negative pressure for the label before the label is attached to the container, so that the label is flat before being attached to the container.

[0045] The brush plate can also keep the label flat during the labeling process to avoid corner folding or wrinkling. However, the effect of using the brush plate alone is not high. For large-volume containers, such as bottled water with a volume of about 20L, using the brush plate alone will easily cause the label to fold. With the help of the adsorption plate 1, the label can be flatly and snugly attached to the outer wall of the container.

[0046] The brush plate can be made of wear-resistant and high-temperature resistant materials, such as rubber, silicone or plastic. These materials have a certain elasticity and friction. During the operation of the labeling machine, the brush plate will contact the label according to the set pressure and speed, and smoothly feed the label from the roll into the labeling part to ensure that the label can be smoothly attached to the product surface later.

[0047] In addition to keeping the label flat, the brush plate can also play a role in cleaning and positioning. During the operation of the label machine, the brush plate can remove dust and impurities on the surface of the label, making the label clean and tidy. At the same time, the brush plate also keeps the label in the correct position and direction during the laminating process, ensuring the accuracy and consistency of the label laminating.

[0048] See also Figures 1 to 4 , an embodiment of the utility model provides a label adsorption device, including an adsorption plate 1, a first negative pressure flow channel (not shown in the figure), a second negative pressure flow channel (not shown in the figure) and a negative pressure source (not shown in the figure). The adsorption plate 1 includes a main body and a plurality of through holes 11 arranged on the main body, and the through holes 11 are at least divided into a first group of holes and a second group of holes. The first negative pressure flow channel is connected to each through hole 11 of the first group of holes. The second negative pressure flow channel is connected to each through hole 11 of the second group of holes. The negative pressure source is connected to both the first negative pressure flow channel and the second negative pressure flow channel, so that the first negative pressure flow channel and the second negative pressure flow channel maintain negative pressure.

[0049] The adsorption plate 1 is used to adsorb the label so that the surface of the label is flat. Before the label is attached to the container, at least part of the label can be adsorbed on the surface of the adsorption plate 1. In this way, the label is very flat and is not prone to corner folding when it is subsequently attached to the container surface, thereby improving product quality, reducing product losses caused by unqualified label attachment during the production process, and improving finished product production efficiency.

[0050] The surface of the adsorption plate 1 for adsorbing the label is flat, and the adsorption plate 1 fits the label surface to surface and provides adsorption force for the label. If the label to be attached is a special-shaped label, the adsorption plate 1 is also made into a special shape accordingly, so that the adsorption plate 1 can always adsorb the label surface to surface. The first negative pressure flow channel provides negative pressure for each through hole 11 of the first group of holes, and the second negative pressure flow channel provides negative pressure for each through hole 11 of the second group of holes.

[0051] The vacuum degree, adsorption force, and presence or absence of adsorption force of the first negative pressure flow channel and the second negative pressure flow channel can be adjusted separately without affecting each other.

[0052] The adsorption plate 1 uses the first negative pressure channel, the second negative pressure channel, the negative pressure source and other components to extract the air in the through hole 11, generate negative pressure, and thus generate adsorption force to fix the label on the adsorption plate. When the vacuum pump is started, the air in the through hole 11 is extracted to form a vacuum state, and adsorption force is generated between the adsorption plate and the label. By controlling the working state of the vacuum pump and the size of the adsorption force, the label can be accurately fixed and released, so as to achieve fast and stable fixation of the label, and improve the production efficiency and product quality of the attached label.

[0053] In some embodiments, the label adsorption device further includes a first switching valve (not shown) and / or a second switching valve (not shown). The first switching valve is disposed in the first negative pressure flow channel to control the conduction and disconnection of the first negative pressure flow channel. The second switching valve is disposed in the second negative pressure flow channel to control the conduction and disconnection of the second negative pressure flow channel.

[0054] The first switching valve and the second switching valve can adopt the same structure or different structures. The specific type can be a solenoid valve. The first switching valve and the second switching valve can realize the control of the first negative pressure flow channel and the second negative pressure flow channel respectively by switching their own valve positions. Figure 1 In the embodiment, the adsorption plate 1 is divided into two areas, a first group of holes and a second group of holes. In other embodiments, the adsorption plate 1 can also be divided into more areas, and each area can be controlled individually or in a linkage manner.

[0055] See also Figure 4In some embodiments, the adsorption plate 1 includes a contact plate layer 12, a support plate layer 13 and a partition (not shown). The contact plate layer 12 is a component that directly contacts the label. The contact plate layer 12 includes a concave smooth curved surface 121. The smooth curved surface 121 is constructed to be in surface contact with the label. The smooth curved surface 121 can be in surface contact with the label. The through hole 11 passes through the smooth curved surface 121. The through hole 11 is connected to the first negative pressure flow channel and the second negative pressure flow channel. The through hole 11 can provide negative pressure for the label. The support plate layer 13 is fixedly connected to the contact plate layer 12. The contact plate layer 12 and the support plate layer 13 form a cavity, and the cavity is convenient for forming a negative pressure cavity. The support plate layer 13 includes a first mounting hole and a second mounting hole. The first mounting hole is connected to the first negative pressure flow channel, and the second mounting hole is connected to the second negative pressure flow channel. The partition is arranged in the cavity to divide the cavity into two independent cavities: a first cavity and a second cavity. The first mounting hole is communicated with the first cavity, and the second mounting hole is communicated with the second cavity.

[0056] The negative pressure parameters (negative pressure size, negative pressure on and off, etc.) in the first negative pressure flow channel can be adjusted. The negative pressure parameters (negative pressure size, negative pressure on and off, etc.) in the second negative pressure flow channel can also be adjusted. The first negative pressure flow channel and the second negative pressure flow channel are adjusted separately and do not affect each other.

[0057] The negative pressures of the first negative pressure channel and the second negative pressure channel may be different, so that negative pressures with different adsorption forces can be provided to different areas of the label. In addition, negative pressures with different adsorption forces can also be provided according to labels of different sizes and structures to meet the adsorption requirements of various types of labels.

[0058] Back to Figure 2 In some embodiments, the diameter D of the through hole 11 is 1.8 mm to 2.2 mm, specifically 1.8 mm, 2 mm, and 2.2 mm. The through hole 11 has the above size, and the adsorption force is better.

[0059] The through holes 11 are arranged in an array in one area, which can provide a more uniform force surface for the label, so that the label can be transmitted smoothly.

[0060] Continue to see Figure 1 and Figure 2 In some embodiments, the through holes 11 are arranged in different areas on the adsorption plate 1, and each area is provided with a plurality of through holes 11. The through holes 11 in each area can be arranged in a rectangular matrix or a circular matrix. The distribution area of ​​the through holes 11 corresponds to the position where the label is to be adsorbed. For example, if the key point is to prevent the corner area of ​​the label from bending, the distribution area of ​​the through holes 11 should be able to completely adsorb the area of ​​the label that is easy to bend. Before the area is pasted to the container, the through holes 11 can provide adsorption force for the label.

[0061] See also Figure 3As described above, the contact plate layer 12 includes a concave smooth arc surface 121, and the curvature of the smooth arc surface 121 is the same as the curvature of the outer wall of the matching container. As the container rotates through the contact plate layer, the label can be smoothly attached to the outer wall of the container.

[0062] Continue to see Figure 2 and Figure 3 The length of the contact plate layer 12 is a set value, which just meets the optimal overlapping position of the turntable 2 revolution, container and label rotation. The length of the contact plate layer 12 is proportional to the outer circumference of the container. The larger the container, the larger the length L of the contact plate layer 12.

[0063] See also Figure 5 In some embodiments, the label adsorption device further includes a turntable 2 and a bracket 3. The turntable 2 is configured to rotate around its own central axis; the bracket 3 is mounted on the circumferential edge of the turntable 2, and the bracket 3 is configured to rotate around its own central axis; the bracket 3 is configured to place a container. The adsorption plate 1 is disposed on the circumferential edge of the turntable 2 and is located outside the bracket 3 along the radial direction of the turntable 2; the adsorption plate is configured to adsorb the label for sticking to the outer wall of the container.

[0064] In some embodiments, the label adsorption device further includes a label adsorption drum 4, which is located outside the turntable 2 and cooperates with the container to stick the label to the container. The adsorption plate 1 is located downstream of the label adsorption drum 4, and the bottled water sticks a label from the label adsorption drum 4, and the stuck label is sucked by the adsorption plate 1. With the rotation of the container and the rotation of the turntable 2, the label is completely adsorbed to the outer wall of the container.

[0065] The label adsorption device provided by the above technical solution can have the length of the adsorption plate 1 set according to different types of containers, so as to be compatible with more round bottles of different capacities, and can also be compatible with the production of rectangular bottles. Moreover, the attachment effect of large-capacity and large-label products is better, which is not possible with the existing labeling structure; in the actual production process, after using the label adsorption device, the label will not be folded after being attached to the outer wall of the container, thereby improving the packaging quality and production efficiency.
