[0002] In manufacturing, labeling is an indispensable part of the product packaging process, especially when dealing with large or irregularly shaped items such as cardboard boxes, where the labeling requirements are more complex. Traditional manual labeling methods are not only inefficient but also extremely labor-intensive when labeling cardboard boxes.

[0003] While existing automated labeling devices have improved labeling efficiency to some extent, they are often designed for items of specific sizes, lacking flexibility and unable to adapt to items of different sizes and shapes. When handling items of varying sizes, existing devices often require additional adjustment steps, which not only increases operational complexity but also limits the improvement of labeling efficiency. Furthermore, these devices lack an effective guiding mechanism before labeling, resulting in unstable item positioning during transport and affecting labeling accuracy. Utility Model Content

[0054] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only partial embodiments of the present invention, and not embodiments of the entire invention. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0055] like Figure 1 and Figure 3As shown, this utility model provides a labeling device, which includes a carrying mechanism 10, a positioning mechanism 20, a conveying mechanism 30, and a labeling mechanism 40. The carrying mechanism 10 is used to carry articles and has an infeed end and an outlet end arranged opposite to each other along the extension direction. The positioning mechanism 20 includes a positioning part 21, which is movably arranged and located above the carrying mechanism 10. The extension direction of the positioning part 21 is the same as the extension direction of the carrying mechanism 10. The positioning part 21 is used to move closer to or away from the articles. The conveying mechanism 30 includes a conveying part 31, which is provided on at least a portion of the positioning part 21. The conveying part 31 is movably arranged relative to the positioning part 21 and has a conveying surface located on the side of the corresponding positioning part 21 facing the articles. The conveying surface is used to abut against the surface of the articles and apply force to the articles so that the articles move from the infeed end of the carrying mechanism 10 to the outlet end. The labeling mechanism 40 is used to label the articles.

[0056] By applying the technical solution of this utility model, a positioning mechanism 20, a conveying mechanism 30 with a conveying section 31, and a labeling mechanism 40 are set up to automatically and stably position and convey cartons, and automatically label the surface of the cartons. In this solution, the positioning section 21 plays a positioning and guiding role, effectively controlling the position of the items on the carrying mechanism 10 and preventing the items from shifting or shaking during conveying. The position of the positioning section 21 is adjustable and can be automatically adjusted according to items of different sizes, ensuring accurate positioning and guidance for items of various sizes. This adaptive design allows the labeling device to flexibly cope with items of varying sizes on the production line without frequent shutdowns for adjustments, thereby improving the continuity and efficiency of the production line. In addition, the conveying section 31 is set on the positioning section 21, realizing the integration of positioning and conveying, and improving space utilization. At the same time, the coordinated operation of positioning and conveying simplifies the item handling process, further speeds up the item handling speed, and improves the overall production efficiency. During the item conveying process, the labeling mechanism 40 can automatically affix labels to the items without manual operation, improving production efficiency. The labeling device is highly automated and easy to operate, which effectively improves production efficiency and saves labor costs.

[0057] In this embodiment, the supporting mechanism 10 includes a frame and multiple conveying rollers. The frame serves as the basic support for the labeling device. Along the feed end to the discharge end of the supporting mechanism 10, the multiple conveying rollers are arranged parallel to each other on the frame. The axial directions of the multiple conveying rollers are perpendicular to the extension direction of the supporting mechanism 10, and the conveying rollers are rotatably mounted on the frame. The multiple conveying rollers provide stable support for the items mounted on the frame, enabling the labeling device to operate stably. With this arrangement, when cartons are placed on the multiple conveying rollers for transport, the rolling conveying rollers reduce the friction experienced by the cartons during transport, improving the stability of the cartons during transport.

[0058] Specifically, when the labeling device labels the cartons, it first places the cartons on the conveyor rollers at the feed end of the carrying mechanism 10. The positioning part 21 of the positioning mechanism 20 gradually approaches the item until the positioning part 21 contacts the item, thus completing the positioning of the item. Then, the conveying part 31 on the positioning part 21 is activated, and the conveying surface of the conveying part 31 contacts the item. The conveying surface applies a force in the forward direction to the item, causing the item to move from the feed end of the carrying mechanism 10 to the discharge end. When the item moves to the preset labeling position, the labeling mechanism 40 affixes the label to the labeling position on the item, thus completing the labeling operation.

[0059] Specifically, the conveying part 31 of the conveying mechanism 30 can work in conjunction with the positioning part 21 to continuously push the item towards the discharge end through the contact and force application between the conveying surface and the surface of the item, thereby realizing automatic, continuous and stable conveying of the item and improving production efficiency.

[0060] like Figure 1 and Figure 2 As shown, the labeling device further includes a first sensing unit 50 and a control unit 60. The first sensing unit 50 is located at the feeding end of the carrying mechanism 10 and is used to identify items. The control unit 60 is electrically connected to both the first sensing unit 50 and the positioning mechanism 20. The control unit 60 controls the working state of the positioning mechanism 20 based on the information of the items identified by the first sensing unit 50 to adjust the position and moving speed of the positioning unit 21. With this configuration, through the cooperation of the first sensing unit 50 and the control unit 60, the control unit 60 can accurately control the position and moving speed of the positioning unit 21, improving the positioning accuracy of the positioning unit 21 for the items, thereby improving the stability and reliability of subsequent transportation of the items.

[0061] Specifically, the first sensor 50 can automatically and promptly identify the item. After the first sensor 50 identifies the item, it sends the identification signal to the control unit 60. The control unit 60 sends an instruction to the positioning mechanism 20 according to the identification signal. The control unit 60 can accurately control the positioning mechanism 20 so that the positioning unit 21 starts to move at a suitable speed. The positioning unit 21 begins to approach the item until the conveying surface of the conveying unit 31 contacts the item, so as to carry out the subsequent stable conveying process of the item.

[0062] Furthermore, the first sensing unit 50 includes a first sensor 51 and a second sensor 52. The first sensor 51 is disposed at the feeding end of the carrying mechanism 10 and is used to identify whether an item enters the feeding end. The second sensor 52 is located downstream of the first sensor 51 and is used to identify the size information of the item. The first sensor 51 and the second sensor 52 work together to more accurately identify the item, so that the positioning mechanism 20 can more accurately position the item.

[0063] In this design, when the first sensor 51 detects that an item has entered the feeding end, the positioning unit 21 begins to move closer to the item. The second sensor 52 accurately identifies the size information of the item. Based on the size information detected by the second sensor 52, the control unit 60 can control the moving speed of the positioning unit 21 to achieve more accurate positioning of the item. The first sensor 51 and the second sensor 52 cooperate with each other to assist the positioning mechanism 20 in accurately positioning the item, improving the controllability and stability of the labeling device.

[0064] Furthermore, the second sensor 52 is a contact sensor, comprising a base 521 and a contact portion 522. The base 521 is disposed on the positioning portion 21, and the contact portion 522 is pivotally disposed on the base 521. The end of the contact portion 522 away from the base 521 protrudes from the positioning portion 21 and the base 521 towards the object, and this end is used to contact the object. The second sensor 52 can more accurately identify the position of the object based on its contact with it, thus assisting the positioning portion 21 in positioning the object more flexibly and accurately.

[0065] Specifically, the contact portion 522 is swayably disposed on the base 521, and the end of the contact portion 522 away from the base 521 protrudes from the positioning portion 21 and the base 521 towards the object. When the contact portion 522 is not in contact with the object, the positioning portion 21 approaches the object at a relatively fast speed. When the contact portion 522 begins to contact the object, the control member 60 controls the positioning portion 21 to slow down its approach speed towards the object, approaching the object slowly at a relatively slow speed. Subsequently, as the positioning portion 21 gradually approaches the object, the contact portion 522 in contact with the object is gradually squeezed and swayed by the object, and the angle between the contact portion 522 and the extension direction of the bearing mechanism 10 gradually decreases until the contact portion 522 is parallel to the extension direction of the bearing mechanism 10. At this point, it indicates that the positioning portion 21 has completed positioning the object, the conveying surface of the conveying portion 31 contacts the object, and the control member 60 controls the positioning portion 21 to stop moving. Under the action of the conveying portion 31, the object is driven forward.

[0066] The above configuration ensures that when the first sensor 51 detects an item but the second sensor 52 is not in contact with it, the positioning unit 21 approaches the item at a first speed. After the second sensor 52 contacts the item, the positioning unit 21 approaches the item at a second speed, which is less than the first speed. This configuration guarantees the positioning speed of the positioning unit 21 and reduces the possibility of the positioning unit 21 squeezing the item.

[0067] Furthermore, the positioning unit 21 includes a first positioning unit 211 and a second positioning unit 212, which are spaced apart along the width direction of the carrying mechanism 10. The first positioning unit 211 and the second positioning unit 212 move closer to or further away from each other synchronously. A conveying unit 31 is movably provided on each of the first positioning unit 211 and the second positioning unit 212. This arrangement allows the first positioning unit 211 and the second positioning unit 212 to cooperate in positioning the item in two directions, enabling the item to be stably clamped on both sides, thus improving the stability and positional accuracy of the item during transportation.

[0068] In this embodiment of the solution, when the positioning unit 21 positions the item, the first positioning unit 211 and the second positioning unit 212 simultaneously approach the item and position it simultaneously from both sides, effectively improving the positioning accuracy. After positioning is completed, the first positioning unit 211 and the second positioning unit 212 stably clamp the item from both sides. Subsequently, the conveying unit 31 on the first positioning unit 211 and the second positioning unit 212 starts synchronously, working together to drive the item forward, improving the stability of the item during transportation.

[0069] In this embodiment of the solution, the conveying unit 31 includes a conveyor belt that extends along the extension direction of the corresponding positioning unit 21, and the outer surface of the conveyor belt forms a conveying surface.

[0070] like Figures 1 to 4 As shown, the conveying mechanism 30 further includes a first driving unit 70 and a first transmission unit 80. The first driving unit 70 is mounted on the carrying mechanism 10. The first transmission unit 80 is connected to the first driving unit 70 and the first positioning unit 211 and the second positioning unit 212, respectively. The first driving unit 70 drives the two positioning units 211 and 212 to move closer or further apart synchronously through the first transmission unit 80. This configuration enables precise synchronous movement of the first positioning units 211 and 212, achieving synchronous clamping of both sides of the item and improving the accuracy and stability of the positioning unit 21 in positioning the item.

[0071] In this solution, by cooperating with the first transmission unit 80, only one first drive unit 70 is needed to achieve synchronous drive control of the first positioning unit 211 and the second positioning unit 212, which simplifies the drive control system, reduces the complexity of the equipment, and improves the reliability and stability of the labeling device.

[0072] Furthermore, the first transmission unit 80 includes a first lead screw 81, which extends along the width direction of the bearing mechanism 10. The first lead screw 81 is rotatably mounted on the bearing mechanism 10. The first lead screw 81 has a first threaded section and a second threaded section that are connected to each other along the extension direction. The first threaded section and the second threaded section have opposite directions of rotation. The first drive unit 70 is drivenly connected to the first lead screw 81, the first positioning part 211 is threadedly connected to the first threaded section, and the second positioning part 212 is threadedly connected to the second threaded section. With this configuration, the first lead screw 81 enables synchronous driving of the first positioning part 211 and the second positioning part 212, improving the motion synchronization of the first positioning part 211 and the second positioning part 212.

[0073] Specifically, when the positioning part 21 positions the item, the first drive part 70 drives the first lead screw 81 of the first transmission part 80 to rotate, and the first threaded section and the second threaded section rotate in opposite directions. The first positioning part 211 is threadedly connected to the first threaded section, and the second positioning part 212 is threadedly connected to the second threaded section. The first positioning part 211 and the second positioning part 212 will move closer to or further away from the item in sync.

[0074] Furthermore, the first transmission unit 80 also includes a second lead screw 82 and a first linkage mechanism 83. The second lead screw 82 is parallel to the first lead screw 81, and the second lead screw 82 and the first lead screw 81 are spaced apart along the extension direction of the bearing mechanism 10. The second lead screw 82 is rotatably mounted on the bearing mechanism 10. The second lead screw 82 has a third threaded section and a fourth threaded section that are connected to each other along the extension direction. The third threaded section and the fourth threaded section have opposite rotation directions. The first positioning part 211 is threadedly connected to the third threaded section, and the second positioning part 212 is threadedly connected to the fourth threaded section. The rotation direction of the third threaded section is opposite to that of the first threaded section. The first lead screw 81 and the second lead screw 82 rotate synchronously in opposite directions. The first linkage mechanism 83 is connected to the first lead screw 81 and the second lead screw 82 respectively, so that the second lead screw 82 and the first lead screw 81 rotate synchronously. This arrangement further increases the motion synchronization of the first positioning part 211 and the second positioning part 212, and improves the positioning accuracy of the item.

[0075] Specifically, when the first lead screw 81 rotates, the first linkage mechanism 83 causes the second lead screw 82 to rotate in the opposite direction to the first lead screw 81. Under the combined action of the first threaded section of the first lead screw 81 and the third threaded section of the second lead screw 82, the first positioning part 211 will move, and the combined action of the first threaded section and the third threaded section will make the movement of the first positioning part 211 more precise and stable. Similarly, under the combined action of the second threaded section of the first lead screw 81 and the fourth threaded section of the second lead screw 82, the second positioning part 212 will move in the opposite direction to the first positioning part 211, and the second threaded section and the fourth threaded section will also make the movement of the second positioning part 212 more precise and stable.

[0076] In this embodiment of the solution, the movement of the first positioning part 211 and the second positioning part 212 is simultaneously driven and controlled by the first lead screw 81 and the second lead screw 82. Compared with driving by only one lead screw, this setting further increases the stability and accuracy of the movement of the first positioning part 211 and the second positioning part 212, effectively reduces the positioning deviation of the item, and improves the synchronization of the movement of the first positioning part 211 and the second positioning part 212.

[0077] Specifically, the first linkage mechanism 83 includes a drive shaft 831, a first bevel gear 832 and a second bevel gear 833 meshing with each other, a third bevel gear 834 meshing with each other, and a fourth bevel gear 835 meshing with each other. The drive shaft 831 extends along the direction from the first lead screw 81 to the second lead screw 82. The drive shaft 831 is rotatably mounted on the bearing mechanism 10 and is located on the same side of the first lead screw 81 and the second lead screw 82. The first bevel gear 832 is coaxial with the drive shaft 831 and is mounted on the end of the drive shaft 831 near the first lead screw 81. The second bevel gear 833 is coaxial with the first lead screw 81 and is mounted on the end of the first lead screw 81 near the drive shaft 831. The third bevel gear 834 is coaxial with the drive shaft 831 and is mounted on the end of the drive shaft 831 near the second lead screw 82. The fourth bevel gear 835 is coaxial with the second lead screw 82 and is mounted on the end of the second lead screw 82 near the drive shaft 831. This configuration improves the synchronization of the movement of the first lead screw 81 and the second lead screw 82, which helps to improve the positioning accuracy of the positioning unit 21 for the object.

[0078] Specifically, when the first lead screw 81 rotates, the second bevel gear 833 on the first lead screw 81 drives the first bevel gear 832 to rotate, causing the transmission shaft 831, which is coaxially fixedly connected to the first bevel gear 832, to rotate. This causes the third bevel gear 834, which is mounted on the transmission shaft 831, to rotate. The third bevel gear 834 drives the fourth bevel gear 835, which meshes with the third bevel gear 834, to rotate. The fourth bevel gear 835 causes the second lead screw 82, which is coaxially fixedly connected to the fourth bevel gear 835, to rotate synchronously with the first lead screw 81, and the rotation direction of the second lead screw 82 is opposite to that of the first lead screw 81.

[0079] like Figure 1 and Figure 5 As shown, the positioning unit 21 further includes a third positioning unit 213, which is disposed opposite to the support mechanism 10 and is located near or away from the support mechanism 10. With this arrangement, the third positioning unit 213 can position the top of the item, further improving the accuracy of the item positioning, and will not interfere with the first positioning unit 211 and the second positioning unit 212.

[0080] Furthermore, the positioning mechanism 20 includes a mounting frame 22, at least a portion of which is located above the support mechanism 10. The third positioning part 213 is vertically and flexibly mounted on the mounting frame 22. The labeling device also includes a second drive part 90 and a second transmission part 100. The second drive part 90 is mounted on the mounting frame 22. The second transmission part 100 is connected to both the mounting frame 22 and the third positioning part 213. The second drive part 90 is driven by the third positioning part 213 via the second transmission part 100, causing the third positioning part 213 to rise and fall. This arrangement allows the second drive part 90 to accurately and stably control the rising and falling of the third positioning part 213, improving the motion accuracy of the third positioning part 213 and facilitating precise positioning of the item.

[0081] In this embodiment, the mounting bracket 22 provides stable support for the third positioning part 213, ensuring its stable lifting and lowering. The second drive unit 90 drives the third positioning part 213 to lift and lower stably via the second transmission unit 100, thereby accurately positioning the item in the vertical direction.

[0082] Furthermore, the second transmission unit 100 includes a third lead screw 101, a fourth lead screw 102, and a second linkage mechanism 103. The third lead screw 101 extends vertically and is rotatably mounted on the mounting bracket 22. The third lead screw 101 passes through the third positioning part 213 and is threadedly connected to the third positioning part 213. The fourth lead screw 102 is parallel to the third lead screw 101 and is rotatably mounted on the mounting bracket 22. The fourth lead screw 102 passes through the third positioning part 213 and is threadedly connected to the third positioning part 213. The second linkage mechanism 103 is connected to the third lead screw 101 and the fourth lead screw 102 respectively, so that the third lead screw 101 and the fourth lead screw 102 rotate synchronously. With this configuration, the third lead screw 101 and the fourth lead screw 102 rotate synchronously, so that the third lead screw 101 and the fourth lead screw 102 simultaneously drive the third positioning part 213 to rise and fall. This allows for a more even application of lifting force to both ends of the third positioning part 213 in the width direction, thereby improving the stability and reliability of the lifting of the third positioning part 213.

[0083] Furthermore, the second linkage mechanism 103 includes a first transmission wheel 1031, a second transmission wheel 1032, and a transmission belt 1033. The first transmission wheel 1031 is coaxial with and mounted on the third lead screw 101; the second transmission wheel 1032 is coaxial with and mounted on the fourth lead screw 102; and the transmission belt 1033 is sleeved on the first transmission wheel 1031 and the second transmission wheel 1032. This arrangement enables synchronous rotation of the third lead screw 101 and the fourth lead screw 102 via belt drive, thereby allowing the third positioning part 213 to rise and fall stably. The structure is simple and reliable.

[0084] like Figure 1, Figure 6 and Figure 7 As shown, the labeling mechanism 40 further includes a first labeling component 41 and a second labeling component 42. The first labeling component 41 is disposed on the side of the support mechanism 10 and is used to label the top surface of the item. The second labeling component 42 is disposed at the bottom of the support mechanism 10 and is used to label the bottom surface of the item. Through the first labeling component 41 and the second labeling component 42, the top and bottom surfaces of the item can be labeled respectively.

[0085] In this embodiment, the first labeling component 41 includes a first label feeding component 411 and a first label picking component 412. The first label feeding component 411 includes a label feeding frame 4111, a label feeding motor 4112, a label unwinding structure 4113, a label recycling mechanism 4114, a guide wheel 4115, a label picking table 4116, and a linear cylinder. All components of the first label feeding component 411 are mounted on the label feeding frame 4111. The label unwinding structure 4113 is located at the upper end of the label feeding frame 4111, and the label roll is rotatably placed on the label unwinding structure 4113 for unwinding. The guide wheel 4115 can guide the conveying path of the label tape. Under the guidance of the guide wheel 4115, the label tape is conveyed to the label picking table 4116, where the label on the label tape is removed. The remaining empty tape is eventually wound onto the label recycling mechanism 4114.

[0086] The axis of the label unwinding structure 4113 is parallel to the axis of the label recycling mechanism 4114 and perpendicular to the extension direction of the carrying mechanism 10. The label feeding motor 4112 is driven by the label recycling mechanism 4114, and the label feeding motor 4112 can drive the label recycling mechanism 4114 to rotate, thereby driving the label unwinding structure 4113 to convey the label tape.

[0087] The label-dispensing platform 4116 extends along the extension direction of the supporting mechanism 10 and is positioned toward the first label-taking component 412. The label-dispensing platform 4116 has a label-submitting position and a clearance position. The label-dispensing platform 4116 is driven by a linear cylinder, which can drive the label-dispensing platform 4116 to move linearly in the extension direction of the label-dispensing platform 4116, so that the label-dispensing platform 4116 can switch between the label-submitting position and the clearance position.

[0088] The first label-receiving component 412 includes a first linear cylinder 4121, a first rotary cylinder 4122, and a first vacuum suction plate 4123. The first linear cylinder 4121 extends along the height direction, and the output end of the first linear cylinder 4121 is connected to the first rotary cylinder 4122. The first linear cylinder 4121 can drive the first rotary cylinder 4122 to move up and down in the vertical direction. The output end of the first rotary cylinder 4122 is provided with the first vacuum suction plate 4123. The first rotary cylinder 4122 can drive the first vacuum suction plate 4123 to rotate, and the first vacuum suction plate 4123 can pick up the label.

[0089] The first label-taking component 412 is disposed on one side of the first label-feeding component 411. When the label-dispensing platform 4116 is in the label-feeding position, the first vacuum suction plate 4123 is located above the label-dispensing platform 4116 in the vertical direction, and the projection of the first vacuum suction plate 4123 is located within the projection of the label-dispensing platform 4116 in the vertical direction. When the label-dispensing platform 4116 is in the avoidance position, the projection of the first vacuum suction plate 4123 does not coincide with the projection of the label-dispensing platform 4116 in the vertical direction. In the vertical direction, the first vacuum suction plate 4123 is located directly above the labeling position on the top surface of the item.

[0090] When the first labeling component 41 performs the labeling operation, the label dispensing platform 4116 of the first label feeding component moves to the label feeding position, conveying the label tape to below the first vacuum suction plate 4123. The first linear cylinder 4121 of the first label picking component 412 drives the first rotary cylinder 4122 and the first vacuum suction plate 4123 to move downwards until the first vacuum suction plate 4123 contacts the label tape on the label dispensing platform 4116. The first vacuum suction plate 4123 picks up the label on the label tape, and the first linear cylinder 4121 drives the first rotary cylinder 4122 and the first vacuum suction plate 4123 upwards. The label is moved, causing it to detach from the label tape. The label-adjusting platform 4116 then moves to a clearance position. The first linear cylinder 4121 drives the first rotary cylinder 4122 and the first vacuum suction plate 4123 to move downwards until the first vacuum suction plate 4123 contacts the top surface of the item, affixing the label to the top surface. While the first linear cylinder 4121 drives the first rotary cylinder 4122 and the first vacuum suction plate 4123 downwards, the rotary motor 4222 can rotate the first vacuum suction plate 4123 and the label on it as needed, adjusting the label's affixing angle. Subsequently, the first linear cylinder 4121 drives the first rotary cylinder 4122 and the first vacuum suction plate 4123 upwards to return to the initial position.

[0091] The second labeling component 42 includes a second label feeding component 421 and a second label taking component 422. The second label feeding component 421 has the same structure as the first label feeding component 411.

[0092] The second label-taking component 422 includes a frame 4221, a rotary motor 4222, a second linear cylinder 4223, a second rotary cylinder 4224, and a second vacuum suction plate 4225. The rotary motor 4222 is mounted on the support mechanism 10 and is drivenly connected to the frame 4221. The output axis of the rotary motor 4222 is parallel to the axis of the label unwinding structure 4113, and the rotary motor 4222 can drive the frame 4221 to rotate. The second linear cylinder 4223 is mounted on the frame 4221, and the output end of the second linear cylinder 4223 is connected to the second rotary cylinder 4224. The second linear cylinder 4223 can drive the second rotary cylinder 4224 to move linearly. The output end of the second rotary cylinder 4224 is provided with the second vacuum suction plate 4225, and the second rotary cylinder 4224 can drive the second vacuum suction plate 4225 to rotate, and the second vacuum suction plate 4225 can pick up the label.

[0093] The second label-taking component 422 is positioned above the second label-feeding component. When the label-dispensing platform 4116 of the second label-feeding component is in the label-feeding position, the second linear cylinder 4223 in the second label-taking component 422 is in a vertical state, and the second vacuum suction plate 4225 is parallel to the label-dispensing platform 4116. In the vertical direction, the projection of the second vacuum suction plate 4225 is located within the projection of the label-dispensing platform 4116. In the vertical direction, the second vacuum suction plate 4225 is located directly below the labeling position on the bottom surface of the item.

[0094] When the second labeling component 42 performs the labeling operation, the label feeding platform 4116 of the second label feeding component moves to the label feeding position, conveying the label tape to below the second vacuum suction plate 4225; the second linear cylinder 4223 is activated, driving the second rotary cylinder 4224 and the second vacuum suction plate 4225 to move downwards until the second vacuum suction plate 4225 contacts the label tape on the label feeding platform 4116; the second vacuum suction plate 4225 sucks up the label on the label tape, and the second linear cylinder 4223 drives the second rotary cylinder 4224 and the second vacuum suction plate 4225 to move upwards, causing the label to detach from the label tape; then the rotary motor 4222 is activated. The second linear cylinder 4223 rotates the frame 4221 180°, while the second linear cylinder 4223 remains vertical. The second vacuum suction plate 4225 is parallel to the label-adjusting platform 4116 and aligned with the label-adjusting position on the bottom of the item. The second linear cylinder 4223 then activates, moving the second rotary cylinder 4224 and the second vacuum suction plate 4225 upwards. Simultaneously, the second rotary cylinder 4224 can rotate the second vacuum suction plate 4225 as needed to adjust the label-adjusting angle until the second vacuum suction plate 4225 contacts the bottom of the item, affixing the label to the bottom and completing the labeling operation. Subsequently, the second linear cylinder 4223 moves the second rotary cylinder 4224 and the second vacuum suction plate 4225 downwards, and the rotary motor 4222 drives the frame 4221 to rotate 180°, returning the second label-adjusting component 422 to its initial state.

[0095] like Figure 1 and Figure 8 As shown, the labeling device further includes a sealing mechanism 110, which is located downstream of the labeling mechanism 40. The sealing mechanism 110 is used to apply adhesive tape to the items. After the labeling mechanism 40 completes the labeling operation on the items, the conveying mechanism 30 continues to convey the items. When the items move to the sealing position, the sealing mechanism 110 can automatically seal the items, making the operation convenient.

[0096] Furthermore, the sealing mechanism 110 includes a first sealing component 111 and a second sealing component 112. The first sealing component 111 is disposed on the side of the support mechanism 10 and is used to apply tape to the top surface of the item. The second sealing component 112 is disposed at the bottom of the support mechanism 10 and is used to apply tape to the bottom surface of the item.

[0097] In this embodiment, the first sealing assembly 111 includes a sealing frame 113, a spring unwinding structure 114, a tape guide roller assembly 115, a first spring pressure roller 116, a second spring pressure roller 117, and a cutter. The tape is rotatably placed on the spring unwinding structure 114, and the tape can be wound and unwound on the spring unwinding structure 114. The tape guide roller assembly 115 can guide the path of the tape. Under the guidance of the tape guide roller assembly 115, after the tape is output from the spring unwinding structure 114, it passes through the first spring pressure roller 116 and the second spring pressure roller 117 in sequence, and finally wraps around the second spring pressure roller 117. The axial direction of the first spring pressure roller 116 and the second spring pressure roller 117 is parallel to the width direction of the bearing mechanism 10. The first spring pressure roller 116 and the second spring pressure roller 117 are located at one end of the sealing frame 113 near the top surface of the item.

[0098] When the first sealing assembly 111 applies tape to the top surface of the item, as the item moves forward, the top surface of the item comes into contact with the first spring pressure roller 116 and the second spring pressure roller 117 in sequence. As the item moves forward, the first spring pressure roller 116 and the second spring pressure roller 117 will press the tape onto the top surface of the item and flatten the tape, thus completing the application of tape to the top surface of the item. During this process, the tape on the spring unwinding structure 114 will continue to unwind. After the item is conveyed away, the cutter falls and cuts the tape.

[0099] The second sealing assembly 112 has the same structure and working principle as the first sealing assembly 111. The second sealing assembly is set at the bottom of the support mechanism 10. The second sealing assembly 112 applies tape to the bottom surface of the item. In the second sealing assembly 112, the first spring pressure roller 116 and the second spring pressure roller 117 are set on the sealing frame 113 at one end near the bottom surface of the item.

[0100] like Figure 1 As shown, the labeling device further includes a guiding mechanism 120, which comprises two guiding sections located upstream of the positioning mechanism 20 and above the supporting mechanism 10. The two guiding sections are spaced apart along the width of the supporting mechanism 10, forming a guiding channel between them. The spacing between the two guiding sections is adjustable. This arrangement allows the positioning mechanism 20 to pre-guide and pre-position the item before positioning it, improving the positioning accuracy during the subsequent positioning process.

[0101] In this embodiment of the solution, the distance between the two guide parts can be pre-adjusted according to the shape and size of the item. The staff puts the item into the guide channel for preliminary guidance and pre-positioning. In this way, when the positioning mechanism 20 positions the item, the item will not undergo large displacement, which helps to improve the positioning accuracy of the item and improves the stability and reliability of the labeling device.
