[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.
[0025] like Figure 1As shown, an embodiment of the present application provides an automatic double-sided labeling device for cartons, including a conveying mechanism 1 and a labeling mechanism 2, the conveying mechanism 1 includes a workbench 11, a roller assembly 12 is rotatably arranged on the workbench 11, two conveying lines 13 for driving the carton 3 to move are symmetrically slidably arranged at both ends of the workbench 11, and a first driving mechanism for driving the two conveying lines 13 to move relative to each other is arranged between the two conveying lines 13.
[0026] like Figure 1 As shown, the labeling mechanism 2 includes a support frame 21, on which a lifting drive mechanism 22, a first labeling mechanism 23 for labeling the top surface of the carton 3 and a second labeling mechanism 24 for labeling the bottom surface of the carton 3 are provided. The lifting drive mechanism 22 is installed at the side end of the support frame 21, and the driving end of the lifting drive mechanism 22 is connected to the first labeling mechanism 23. The first labeling mechanism 23 is located above the workbench 11, and the second labeling mechanism 24 is connected to the support frame 21. The second labeling mechanism 24 is located below the roller assembly 12, and a gap 121 is provided on the roller assembly 12 for the second labeling mechanism 24 to label. The first labeling mechanism 23 and the second labeling mechanism 24 are arranged opposite to each other.
[0027] Specifically, when the carton 3 flows onto the roller assembly 12 of the workbench 11, the photoelectric sensor 14 on the workbench 11 detects the carton 3, and the first drive mechanism drives the two conveyor lines 13 to move relative to each other to clamp the carton 3 in the center. The two conveyor lines 13 convey the carton 3. After conveying to the designated position, the lifting drive mechanism 22 drives the first labeling mechanism 23 to move downward to label the top surface of the carton 3, and at the same time, the second labeling mechanism 24 labels the bottom surface of the carton 3. After the upper and lower surfaces of the carton 3 are labeled, they flow out of the workbench 11.
[0028] In the above structure, the provision of the first labeling mechanism 23 and the second labeling mechanism 24 not only enables automated double-sided labeling of cartons 3, but also improves labeling speed, achieving a labeling accuracy of + / - 1 mm. Furthermore, the provision of the first labeling mechanism 23 with automatic height adjustment can meet the labeling requirements of cartons 3 with sizes ranging from 100 to 500 mm. This automatic double-sided carton labeling equipment not only enables automated double-sided labeling of cartons 3, but also significantly improves labeling efficiency, saves time and labor costs, and enhances versatility.
[0029] like Figure 3As shown, in one embodiment, the first labeling mechanism 23 and the second labeling mechanism 24 of the carton double-sided automatic labeling equipment have the same structure, the first labeling mechanism 23 includes a labeling component 231 and an adjustment component 232 for adjusting the horizontal position of the labeling component 231, the labeling component 231 includes a fixed plate 100, the fixed plate 100 is provided with a reeling shaft 101 for reeling the label tape, a guide shaft component 102 for tensioning and guiding the label tape, a material-discharging and rolling component 103 for peeling and rolling the label, a tensioning component 104 for tensioning the label tape, a reeling shaft 105 for recycling the bottom tape of the label tape and a second driving mechanism 106 for driving the reeling shaft 105 and the tensioning component 104 to rotate, a guide block 107 is provided between the guide shaft component 102, and the guide block 107 is provided with a guide groove 001 for guiding the label tape. The label tape is placed on the unwinding shaft 101, and the label tape passes through the guide shaft assembly 102, the guide groove 001 of the guide block 107, the material stripping plate 002 of the material stripping roller pressing assembly 103, the guide shaft assembly 102 and the tensioning assembly 104 in sequence, and finally is wound on the reeling shaft 105. The second driving mechanism 106 drives the reeling shaft 105 and the tensioning roller of the tensioning assembly 104 to rotate, and the reeling shaft 105 and the tensioning roller pull the label tape to move. When the carton 3 is moved to the designated position, the material stripping plate 002 of the material stripping roller pressing assembly 103 peels off the label of the label tape, and the label is attached to the carton 3. The carton 3 moves, and the roller 003 rolls the label so that the label is firmly attached to the carton 3. The unwinding shaft 101 recycles the bottom tape of the label tape, and the tensioning assembly 104 can ensure the flatness of the bottom tape of the label tape. This arrangement not only realizes the automatic feeding of the label tape, but also realizes the positioning, guidance and attachment of the label tape, thereby improving the labeling efficiency of the carton 3 and ensuring the consistency of the labeling of the product.
[0030] like Figure 3 As shown, in one embodiment, the material-dipping and rolling assembly 103 of the automatic double-sided labeling equipment for carton boxes includes a material-dipping plate 002 for peeling the label from the label strip and a roller 003 for rolling the label onto the carton 3. The side end of the material-dipping plate 002 is connected to the fixed plate 100, and the material-dipping plate 002 and the roller 003 are connected by a connecting plate 004. The roller 003 is rotatably connected to the connecting plate 004, and a distance is provided between the material-dipping plate 002 and the roller 003. When the label strip moves to the material-dipping plate 002, the end of the material-dipping plate 002 peels the label, the carton 3 moves, the label is attached to the carton 3, and the roller 003 rolls the label. This arrangement improves the reliability of label attachment.
[0031] like Figure 3 and Figure 4As shown, in one embodiment, the adjustment assembly 232 of the carton double-sided automatic labeling equipment includes an adjustment plate 108, an adjustment handle 109, a screw 110 and a guide column assembly 111. One end of the guide column assembly 111 is connected to the driving end of the lifting drive mechanism 22, and the other end of the guide column assembly 111 passes through the fixed plate 100 and is connected to the adjustment plate 108. The guide column assembly 111 and the fixed plate 100 are connected through a linear bearing 112. One end of the screw 110 is rotatably connected to the driving end of the lifting drive mechanism 22. The other end of the screw 110 passes through the fixed plate 100 and is fixedly connected to the adjustment handle 109. The screw 110 and the fixed plate 100 are threadedly connected by a nut 113. The adjustment handle 109 is used to rotate the screw 110 to drive the fixed plate 100 to move horizontally along the guide column assembly 111. The adjustment assembly 232 of the first labeling mechanism 23 is connected to the driving end of the lifting drive mechanism 22, and the adjustment assembly 232 of the second labeling mechanism 24 is connected to the support frame 21. When labeling is required at different locations on the carton 3, the adjustment handle 109 can be manually rotated. This adjusts the handle 109, which in turn rotates the screw 110, causing the nut 113 of the fixed plate 100 to move horizontally along the screw 110. The nut 113 then moves the fixed plate 100, thereby adjusting the labeling position. This arrangement allows the labeling position to be adjusted across the width of the carton 3, improving the versatility of the labeling equipment.
[0032] like Figure 1 and Figure 2 As shown, in one embodiment, the roller assembly 12 of the automatic double-sided labeling device for cartons includes a plurality of rollers 122, both ends of which are rotatably connected to the workbench 11. The arrangement of the plurality of rollers 122 reduces friction with the cartons 3 and improves the efficiency of moving the cartons 3.
[0033] like Figure 1 and Figure 2 As shown, in one embodiment, the conveyor line 13 of the automatic double-sided labeling equipment for cartons includes a connecting frame, a drive motor 131, a belt line, a driving shaft and a passive shaft. The connecting frame is slidably matched with the workbench 11, and the driving shaft and the passive shaft are rotatably mounted on the two ends of the connecting frame respectively. The belt line is wound around the two driving shafts and the passive shaft. The drive motor 131 is mounted on the connecting frame, and the driving end of the drive motor 131 is connected to the driving shaft. The drive motor 131 is used to drive the driving shaft to drive the belt line and the passive shaft to rotate. The first drive mechanism drives the two conveyor lines 13 to move relative to each other, so that the conveyor lines 13 clamp the carton 3 in the center. The drive motor 131 drives the driving shaft to drive the belt line and the passive shaft to rotate, and the belt line drives the carton 3 to move. This arrangement not only improves the moving efficiency of the carton 3, but also improves the applicability.
[0034] like Figure 2As shown, in one embodiment, a photoelectric sensor 14 is provided on the workbench 11 of the automatic double-sided labeling device for cartons, which is used to detect whether the cartons 3 have been moved into position. This arrangement facilitates the detection of the cartons 3. If the cartons 3 have not flowed onto the roller assembly 12, an alarm signal is promptly issued to notify the staff to handle the problem.
[0035] like Figure 2 As shown, in one embodiment, the first drive mechanism of the automatic double-sided carton labeling system is a centering cylinder, and the lifting drive mechanism 22 is a screw lifting mechanism. The centering cylinder facilitates the relative movement of the two conveyor lines 13. The lifting drive mechanism 22 facilitates the automatic height adjustment of the first labeling mechanism 23.
[0036] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
