In one embodiment, a suction cup may be provided on the suction surface 21. In one embodiment, the label may also be adhered via the suction surface 21. In one embodiment, the blowing hole 22 may be connected to both the blowing unit and the suction unit.

In an embodiment, the plurality of air blowing holes 22 may be respectively and independently arranged, each air blowing hole 22 is correspondingly provided with an air pipe, and the plurality of air blowing holes 22 may be controlled to sequentially blow air or blow air simultaneously along a certain direction. In an embodiment, the plurality of air blowing holes 22 may also be sequentially communicated, that is, two adjacent air blowing holes 22 are communicated. An inlet hole 23 may be provided at the blowhole 22 closest to the first side 2111, and the inlet hole 23 may communicate with the outlet hole. When the air inlet 23 admits air, the distance of the air flow flowing out from the air blowing holes 22 is longer and the time is longer as the air flow is farther away from the air blowing holes 22 on the first side 2111 in the plurality of air blowing holes 22, that is, the air flow flows out in the direction from the first side 2111 to the second side 2112 to form a time difference, so that the plurality of air blowing holes 22 can blow air in sequence. The diameters of the plurality of blowing holes 22 may be the same, or the diameters of the plurality of blowing holes 22 may be gradually increased along a direction from the first side 2111 to the second side 2112, and so on.

At this time, the labels can be blown to the labeling object 90 by blowing through the blowing holes 22, and since the plurality of blowing holes 22 are arranged at intervals in the direction from the first side 2111 to the second side 2112, the plurality of blowing holes 22 can be controlled to blow in sequence from the first side 2111 to the second side 2112, so that the labels on the suction surface 21 can be attached to the labeling object 90 in sequence from the first side 2111 to the second side 2112, that is, the labels are gradually attached to the labeling object 90 in one direction, compared with a mode of covering the labels on the labeling object 90 at one time, the generation of bubbles can be reduced, the condition of label wrinkles can be avoided, the waste of raw materials is reduced, and the manufacturing cost is saved.

Referring to fig. 3 to 5, in an embodiment, the arrangement direction of the plurality of air blowing holes 22 is set corresponding to the middle of the first side 2111. Specifically, the arrangement direction of the plurality of air blowing holes 22 is also arranged corresponding to the middle of the second side 2112, that is, the plurality of air blowing holes 22 are located at or near the connecting line between the middle of the first side 2111 and the middle of the second side 2112. When labelling piece 20 absorbs the label, can be so that the middle part of label corresponds the middle part of first side 2111 and the middle part of second side 2112, so blow hole 22 can blow the label to labelling object 90 from the middle part of label, and when the air current blew out from blow hole 22, the middle part of label atress earlier, the air current can flow to all around afterwards, can make label both sides atress even, also can make the label can laminate gradually on labelling object 90 from the middle part towards both sides, can reduce the production of bubble, labelling quality has been improved. Of course, in other embodiments, the center of the blow hole 22 offset from the first side 2111 may be provided, and so on. For example, a plurality of sets of the blow holes 22 and the like may be provided side by side on the suction surface 21.

In one embodiment, the blowing hole 22 has a blowing section 221 and a connecting section 222, the blowing section 221 penetrates through the suction surface 21, the connecting section 222 connects two adjacent blowing sections 221, the connecting section 222 is located at one end of the blowing section 221 far away from the suction surface 21, and the connecting section 222 is arranged in a protruding manner in a direction far away from the suction surface 21. The labeling element 20 is provided with an air inlet 23, and the air inlet 23 is communicated with the air blowing section 222 close to the first side 2111.

When air is introduced through the air inlet hole 23, the air flow can firstly flow out from the air blowing section 221 closest to the first side 2111, the farther the air blowing section 221 away from the first side 2111 is, the longer the path to which the air flow flows is, the longer the time for blowing the air flow from the air blowing section 221 is, and therefore the labels can be sequentially blown by the air blowing sections 221 along the direction from the first side 2111 to the second side 2112.

The connecting section 222 is inclined in a direction away from the suction surface 21 along a direction from the first side 2111 to the second side 2112, and then inclined towards the adjacent blowing section 221 to be connected with the blowing section 221, so that the airflow flowing out of the connecting section 222 flows towards the blowing section 221 first, the airflow flowing out of the previous connecting section 222 is prevented from flowing towards the adjacent connecting section 222 first, the airflow can be ensured to flow towards the blowing sections 221 sequentially along a direction from the first side 2111 to the second side 2112, and the multiple blowing sections 221 can be better ensured to blow air sequentially along a direction from the first side 2111 to the second side 2112. Compared with the mode that each air blowing section 221 is provided with one air pipe, the number of parts of the labeling device can be reduced, the structure of the labeling device is greatly simplified, and the cost is lower. The connecting section 222 may be arc-shaped, or may be formed by two straight holes that are connected to each other and form an included angle, or the like. For example, in one embodiment, the connecting section 222 is an arc-shaped section, which ensures that the airflow can flow along the connecting section 222 well, so that the airflow can flow smoothly.

In one embodiment, suction surface 21 further has a flat section 212, flat section 212 connects to first side 2111, and flat section 212 is configured to abut against labeling object 90. Specifically, inclined section 211 inclines relative to planar section 212, and the area of planar section 212 is less than the area of inclined section 211, and when labeller 20 absorbs the label, the label adsorbs at planar section 212 and inclined section 211, and planar section 212 and subsides mark object 90 butt, and then can support the label on pasting mark object 90. The contact area between the suction surface 21 and the labeling object 90 can be increased by arranging the plane section 212, namely, the abutting area of the label 20 abutting the label on the labeling object 90 can be increased, the stability of the label can be improved, the label is prevented from easily shaking when the label is blown through the blowing holes 22, bubbles can be reduced, and the labeling quality can be improved.

In addition, in order to further ensure the stability of the label absorbed by the label sticking member 20, the plurality of air suction holes 24 are symmetrically arranged with the arrangement direction of the air blowing holes 22 as an axis. In addition, the number of the air suction holes 24 can be set reasonably according to parameters such as the size of the label, for example, when the label is larger, more air suction holes 24 can be arranged. Of course, in other embodiments, the suction holes 24 may be provided only in the inclined section 211.

Step S20, the label is sucked by the labeling element and moved toward the labeling object, so that the label on the first side of the labeling element is abutted against the labeling object and the label on the second side of the labeling element is spaced from the labeling object.

In step S20, the label may be placed on the frame 10 by a receiving device, and the labeler 20 moves on the frame 10 to suck the label from the receiving device. The rack 10 may also be provided with a discharging assembly 50, a receiving assembly and a stripping device 60, and the discharging assembly 50 is provided with a material belt with labels, so that the material belt is connected with the receiving assembly through the stripping device 60, and the receiving assembly collects the material belt. The material belt can be driven to move from the discharging assembly 50 and towards the receiving assembly through the stripping device 60 by traction of the receiving assembly, when the material belt passes through the stripping device 60, the stripping device 60 can separate the labels on the material belt from the material belt, so that the labels can be absorbed by the labeling part 20, and the material belt after label separation is collected on the receiving assembly. After the label is sucked by the labeler 20, the labeler 20 can move to the labeling object 90 and can push the portion of the label on the first side 2111 against the labeling object 90, and the inclined section 211 on the suction surface 21 is spaced from the labeling object 90, i.e. the portion of the label on the inclined section 211 is spaced from the labeling object 90.

And step S30, sequentially controlling the plurality of air blowing holes to blow air to the label along the direction that the first side points to the second side, so that the label sequentially contacts the labeling object along the direction that the first side points to the second side.

In step S30, the plurality of air blowing holes 22 may be respectively and independently disposed, each air blowing hole 22 is correspondingly provided with an air pipe, each air blowing hole can independently blow air into the air blowing hole 22, that is, the plurality of air blowing holes 22 can be controlled to sequentially blow air to the labels along the direction from the first side 2111 to the second side 2112. The plurality of air blowing holes 22 may also be sequentially communicated in a direction from the first side 2111 to the second side 2112, the air inlet hole 23 is formed in a position of the labeling member 20 corresponding to the first side 2111, and the air inlet hole 23 is communicated with the air blowing hole 22 closest to the first side 2111, so that when the air inlet hole 23 is ventilated, the air flow can firstly flow out from the air blowing hole 22 closest to the first side 2111 and can sequentially flow to the plurality of air blowing holes 22 in a direction from the first side 2111 to the second side 2112, and then the labels can be sequentially blown by the plurality of air blowing holes 22 in a direction from the first side 2111 to the second side 2112. The plurality of air blowing holes 22 can be communicated with one another, an air flow valve is arranged in each air blowing hole 22, the plurality of air flow valves can be independently controlled to be opened and closed, and the plurality of air blowing holes 22 can be controlled to sequentially blow air to the labels along the direction from the first side 2111 to the second side 2112.

In the labeling method of the present invention, when the label is attached to the labeled object 90 by the labeler 20, the portion of the label on the first side 2111 is first brought into contact with the labeled object 90, and the portion of the label on the second side 2112 is spaced from the labeled object 90. At this time, the labels can be blown to the labeling object 90 by blowing through the blowing holes 22, and since the plurality of blowing holes 22 are arranged at intervals in the direction from the first side 2111 to the second side 2112, the plurality of blowing holes 22 can be controlled to blow in sequence from the first side 2111 to the second side 2112, so that the labels on the suction surface 21 can be attached to the labeling object 90 in sequence from the first side 2111 to the second side 2112, that is, the labels are gradually attached to the labeling object 90 in one direction, compared with a mode of covering the labels on the labeling object 90 at one time, the generation of bubbles can be reduced, the condition of label wrinkles can be avoided, the waste of raw materials is reduced, and the manufacturing cost is saved.

Referring to fig. 9, in an embodiment, after the step S30, the method further includes:

step S40, the labeling object is conveyed toward the direction close to the pressure maintaining roller.

In step S40, the labeling object 90 may be conveyed to the pressure maintaining roller 40 by the conveying assembly 70, or the labeling object 90 may be moved to the pressure maintaining roller 40 by a robot or a human, etc.

Step S50, when the labeling object passes through the pressure maintaining roller, the pressure maintaining roller rolls on the label of the labeling object to compress the label and the labeling object.

In step S50, the pressure maintaining roller 40 may be fixed on the frame 10, and when the labeling object 90 is conveyed through the pressure maintaining roller 40, the labeling object 90 translates relative to the pressure maintaining roller 40, and the pressure maintaining roller 40 can roll on the label of the labeling object 90. The pressure maintaining roller 40 may be movably installed on the frame 10, and the conveying may be stopped when the labeling object 90 is conveyed to be close to the pressure maintaining roller 40, and then the pressure maintaining roller 40 moves relative to the labeling object 90 to roll on the label of the labeling object 90.

Through setting up pressurize gyro wheel 40, pressurize gyro wheel 40 can roll and further compress tightly the label and paste mark object 90 on pasting mark object 90's label, and pressurize gyro wheel 40 is from one side of label rolling towards another relative side gradually moreover, and pressurize gyro wheel 40 extrudees the label all the time at rolling in-process, even there is a small amount of bubbles when pasting mark 20 and labeling, and pressurize gyro wheel 40 also can be better with bubble discharge, has further reduced the bubble, has improved and has pasted mark quality.
