[0042] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0043] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0045] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0046] The labeling devices in the prior art are unable to clean the labeling mechanism in time, which leads to low labeling efficiency and poor labeling effect. To solve this problem, a labeling device is provided in this embodiment, such as Figure 1 As shown, the device includes an unwinding mechanism 40, a tensioning mechanism 50, a deflection correcting mechanism 60, a cutting mechanism 70, a labeling mechanism 30 and a cleaning device, wherein a label roll 80 is placed in the unwinding mechanism 40, and the label roll 80 can be wound around the tensioning mechanism 50 and the deflection correcting mechanism 60 in sequence, and cut into label segments 81 at a cutting station 100 of the cutting mechanism 70, and the labeling mechanism 30 includes a labeling wheel 31 and a glue coating member 32, wherein a plurality of adsorption holes are arranged on the periphery of the labeling wheel 31, and the label segments 81 can be adsorbed through the adsorption holes. 1 is adsorbed on the outer periphery of the labeling wheel 31. As the labeling wheel 31 rotates to the glue coating member 32, hot melt adhesive can be coated on the side of the label segment 81 away from the labeling wheel 31. As the labeling wheel 31 continues to rotate, the label segment 81 coated with hot melt adhesive can move to the labeling station 200. The labeling station 200 is provided with a plurality of workpieces 300. Therefore, the labeling mechanism 30 can attach the label segment 81 to the surface of the workpiece 300 at the labeling station 200. Finally, the cleaning device cleans the labeling mechanism 30.

[0047] In the labeling device, the tensioning mechanism 50 can ensure that the label roll 80 is in a taut state during the transmission process, so there will be no dragging phenomenon; and the correction mechanism 60 can ensure that the label roll 80 will never deviate from the preset direction during the transmission process. The combined effect of the two can facilitate cutting it into the required label segment 81 at the cutting station 100. The labeling wheel 31 can complete the application of hot melt adhesive and attach the label segment 81 to the outer surface of the workpiece 300 in sequence by adsorbing the label segment 81 and driving the label segment 81 to rotate, thereby improving the labeling speed; and the cleaning mechanism 20 can clean the labeling wheel 31 of the labeling mechanism 30 in time, ensuring that the outer periphery of the labeling wheel 31 is clean and tidy when it is used next time, thereby improving the working efficiency and ensuring a good labeling effect in the future.

[0048] It should be noted that, in this embodiment, the workpiece 300 is a packaging bottle, and the label segment 81 is a bottle label. In other embodiments, the labeling device can also be applied to labeling of other parts, and the scope of use is not limited in this embodiment.

[0049] Specifically, the cleaning device in this embodiment is as follows: Figure 2-Figure 4 As shown, the cleaning device is applied to the above-mentioned labeling equipment, which has a cutting station 100, a labeling station 200 and a labeling mechanism 30. The cleaning device is arranged between the cutting station 100 and the labeling station 200 of the labeling equipment, and is located on one side of the labeling mechanism 30. The cleaning device includes an adsorption mechanism 10 and a cleaning mechanism 20, wherein one end of the adsorption mechanism 10 has an adsorption port 11, and the adsorption port 11 is arranged directly opposite to the outer periphery of the labeling mechanism 30 (labeling wheel 31), and the other end of the adsorption mechanism 10 is connected to the negative pressure mechanism to adsorb the label segment 81 remaining on the outer periphery of the labeling mechanism 30; the cleaning mechanism 20 is arranged downstream of the adsorption mechanism 10, and the cleaning mechanism 20 includes a cleaning roller 21 and a driving assembly 22, the outer periphery of the cleaning roller 21 can abut against the outer periphery of the labeling mechanism 30, and the driving assembly 22 can drive the cleaning roller 21 to rotate to clean the hot melt adhesive remaining on the outer periphery of the labeling mechanism 30 (labeling wheel 31).

[0050] This device is arranged between the cutting station 100 and the labeling station 200. Therefore, when the labeling wheel 31 rotates from the labeling station 200 to the cutting station 100, the adsorption mechanism 10 can first quickly adsorb the label segment 81 that has not been completely labeled on the periphery of the labeling wheel 31; as the labeling wheel 31 continues to rotate, the cleaning roller 21 of the cleaning mechanism 20 can clean the hot melt adhesive remaining on the periphery of the labeling wheel 31, thereby ensuring that when the labeling wheel 31 rotates to the cutting station 100 again to adsorb the label segment 81, the periphery is cleaner and tidier, ensuring that the next round of hot melt adhesive coating and labeling have good effects, thereby improving the yield rate.

[0051] like Figure 4As shown, the cleaning mechanism 20 includes a shell 23, which is coated on the outer periphery of the cleaning roller 21. An opening is provided on one side of the shell 23 close to the labeling mechanism 30, and the cleaning roller 21 can clean the outer periphery of the labeling mechanism 30 through the opening. If the shell 23 is not provided, the waste residue or hot melt adhesive generated during the cleaning process will splash around, thereby polluting the surrounding working environment. The shell 23 is coated on the outer periphery of the cleaning roller 21, which can effectively prevent waste splashing, and an opening is provided on one side of the shell 23, and the cleaning roller 21 can clean the labeling wheel 31 normally through the opening, and the use effect is good.

[0052] Considering that it is difficult to completely remove the hot melt adhesive by simply relying on the cleaning roller 21, Figure 4 As shown, the cleaning mechanism 20 further includes a detergent bottle 24 and a dispensing pipe 25. The detergent bottle 24 contains a detergent. One end of the dispensing pipe 25 is connected to the detergent bottle 24, and the other end is connected to the housing 23, so that the detergent can be distributed to the periphery of the cleaning roller 21. In this structure, the dispensing pipe 25 can pump the detergent from the detergent bottle 24 and spray it evenly to the periphery of the cleaning roller 21. Under the action of the rotation of the cleaning roller 21, the cleaning work of the labeling wheel 31 is completed quickly and efficiently, ensuring a good cleaning effect.

[0053] It should be noted here that the cleaning roller 21 is made of a flexible material, including but not limited to a sponge roller, a cloth roller, a brush, etc. As long as a good cleaning effect can be ensured and the outer periphery of the labeling wheel 31 is not damaged, no specific limitation is made in this embodiment.

[0054] In order to facilitate the replacement or cleaning of the cleaning roller 21, the driving assembly 22 is detachably connected to the cleaning roller 21. This arrangement can facilitate the subsequent maintenance or replacement of the cleaning roller 21, thereby improving the convenience of use.

[0055] Specifically, Figure 4-Figure 6 As shown, the driving assembly 22 includes a driving shaft 221, and the driving shaft 221 is provided with a driving groove 222 along the axial direction. The cleaning roller 21 is provided with a mounting hole along the axial direction, and a driving pin 211 is provided in the mounting hole. After the driving shaft 221 extends into the mounting hole, the driving pin 211 can be engaged with the driving groove 222. This method can not only simplify the connection relationship between the driving shaft 221 and the driving groove 222, but also facilitate the installation or removal of the cleaning roller 21, so as to facilitate its replacement or cleaning; in addition, the engagement between the driving groove 222 and the driving pin 211 can ensure a good driving relationship, so that the driving assembly 22 can quickly drive the cleaning roller 21 to rotate, so as to ensure the cleaning efficiency.

[0056] It should be noted that, in this embodiment, the driving assembly 22 includes a driving member 224, whose output end is connected to the driving shaft 221, so that the driving member 224 can drive the driving shaft 221 to rotate, and then the driving shaft 221 can continue to drive the cleaning roller 21 to rotate, thereby ensuring a good transmission effect. In addition, the driving member 224 is a rotary motor, which has a simple structure and is easy to install and use, which can effectively reduce costs and improve convenience of use.

[0057] It is further explained that the mounting hole is a through hole, and the drive shaft 221 can pass through the mounting hole, and one end of the drive shaft 221 extending out of the mounting hole is detachably connected to a locking member 223. In this structure, the drive shaft 221 passes through the mounting hole, which can facilitate the installation of the cleaning roller 21, and the locking member 223 can limit the cleaning roller 21, thereby ensuring that the cleaning roller 21 cannot be separated from the drive shaft 221 during the cleaning process, thereby ensuring good cleaning efficiency.

[0058] like Figure 4 As shown, the cleaning mechanism 20 also includes a moving component 26, which is in transmission connection with the separating member, and the separating member can drive the cleaning roller 21 to approach or move away from the labeling mechanism 30 through the moving component 26. When it is necessary to clean the labeling wheel 31 of the labeling structure 30, it is only necessary to drive the moving component 26 through the separating member to move the cleaning roller 21 toward the labeling wheel 31 and make it abut against the outer periphery of the labeling wheel 31. At this time, the driving member 224 is opened to drive the cleaning roller 21 to rotate for cleaning. When the labeling mechanism 30 is not working, the separating member can drive the cleaning roller 21 away from the labeling mechanism 30 through the moving component 26, so that the specific position of the cleaning mechanism 20 can be adjusted according to actual needs to improve practicality.

[0059] Specifically, Figure 4 As shown, the moving assembly 26 includes a bracket 261 and a slide rail 262, wherein the slide rail 262 is fixed at a preset station, the bracket 261 is slidably connected to the slide rail 262, and the telescopic end of the separator is transmission-connected to the bracket 261 to drive the cleaning roller 21 to approach or move away from the labeling mechanism 30. In this structure, after the telescopic end of the separator is extended, it can push the bracket 261 to slide along the extension direction of the slide rail 262. At this time, the bracket 261 can indirectly drive the cleaning roller 21 to move toward the labeling wheel 31, thereby enabling the cleaning roller 21 to effectively clean the labeling wheel 31. Not only is the operation simple, but the bracket 261 and the slide rail 262 are slidably connected, which improves the smoothness of the movement process, thereby ensuring a good use effect.

[0060] It should be noted here that, in the present embodiment, the separation member is a cylinder, which is not only simple in structure but also easy to install and connect, and can effectively reduce costs and improve ease of use.

[0061] In addition, the bracket 261 is provided with a through hole, and the driving shaft 221 can pass through the through hole and the mounting hole in sequence, so as to form a detachable connection with the cleaning roller 21, and the driving member 224 is arranged at the bottom end of the bracket 261. This arrangement can simplify the overall structure, facilitate the installation and fixation of the driving member 224 and the driving shaft 221, and when the separation member is extended and retracted, the bracket 261 can drive the driving member 224, the driving shaft 221 and the cleaning roller 21 to move closer to or away from the cleaning roller 21, thereby improving work efficiency.

[0062] In summary, the cleaning device in this embodiment can timely clean the label segments 81 and hot melt adhesive remaining on the labeling wheel 31. The labeling device in this embodiment can improve the labeling efficiency and ensure a good labeling effect.

[0063] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here.
