Description

Technical Field

[0001] This utility model belongs to the technical field of labeling devices, and specifically relates to an automatic three-dimensional labeling device for square boxes. Background Technology

[0002] Currently, in the labeling industry, more and more manufacturers are adopting in-mold labeling technology. This involves placing pre-printed and cut label paper into an injection mold for injection molding, allowing the label paper to fuse with the injection molded product of the same material and adhere to the surface of the injection molded product. Compared with traditional labeling processes, its advantages of being less prone to peeling off and less prone to wear and fading are widely welcomed.

[0003] For example, Chinese utility model patent with publication number "CN213972235U" discloses a label feeding and forming device, including: a cartridge; a label compartment, disposed on one side of the cartridge and connected to the cartridge, for storing bottom labels and side labels; a label picking mechanism, rotatably disposed in the cartridge corresponding to the label compartment, for picking up and transferring the bottom labels and side labels stored in the label compartment; and a vacuum forming mechanism, for picking up and forming the bottom labels and side labels transferred by the label picking mechanism, and sending the bottom labels and side labels into an injection mold.

[0004] Although the feeding and forming device can automatically label the box body in the mold, the film is adsorbed onto the outside of the box body by a vacuum device in the forming tank. The adsorption effect of this structure is limited. When labeling square boxes, it is difficult to directly adsorb all the labels onto the square box because the square box has multiple sides. The structure of the labeling device needs to be improved.

[0005] In view of this, the applicant conducted in-depth research on the above-mentioned issues, which led to the occurrence of this case. Utility Model Content

[0006] The purpose of this invention is to provide a three-dimensional labeling device with reliable structure and good stability, capable of labeling square boxes.

[0007] To achieve the above objectives, this utility model adopts the following technical solution:

[0008] An automatic three-dimensional labeling device for square boxes includes a label holder support for placing label holders and a mold frame for placing square boxes. The label holder support is provided with a plurality of label holders for placing labels and a label picking mechanism for picking up labels from the label holders and placing them on the square boxes. The label picking mechanism is disposed between the mold frame and the label holder support. The number and position of the label holders correspond to the number of square boxes. The labeling device also includes a drive mechanism for driving the mold frame to move horizontally, a longitudinal movement mechanism disposed on one side of the label holder support, and a label brushing assembly disposed on the longitudinal movement mechanism. The label brushing assembly includes a transversely arranged connecting rod and a label brushing part fixed to one end of the connecting rod away from the longitudinal movement mechanism. The label brushing part is disposed on the movement path of the mold frame. The side of the label brushing part facing the mold frame has a groove adapted to the square box. Two first label brushing elements are fixed on opposite sides of the groove and arranged facing each other, forming a space between the two first label brushing elements for the square box to extend into. A second label brushing element is fixed on the top of the label brushing part and facing upward.

[0009] Furthermore, the label bin includes a base mounted on the label bin support and a storage module mounted on the base for storing labels. The storage module is fixed to the base at an angle upward. A material retrieval slot is provided on the base corresponding to the position of the storage module. The material retrieval slot extends through both ends of the base. The base is also provided with several discharge baffles arranged around the edge of the material retrieval slot.

[0010] Furthermore, the storage module includes several positioning rods arranged around the material receiving groove, and one end of each positioning rod is fixedly connected to the base, while the other end of each positioning rod is provided with a limiting plate.

[0011] Furthermore, the storage module is also provided with a pushing mechanism, which includes several guide posts arranged parallel to the positioning rod and a pushing plate sleeved on the guide posts. The two ends of the guide posts are respectively fixed to the base and the limiting plate, and the pushing plate is arranged corresponding to the material picking groove.

[0012] Furthermore, the label-taking mechanism includes a rotating spindle rotatably mounted on the label bin support and a label-taking fixture mounted on the rotating spindle. The label-taking fixture is positioned corresponding to the material hopper, and the rotating spindle is driven by a motor.

[0013] Furthermore, the label-taking fixture includes a telescopic cylinder mounted on the rotating spindle and a label suction plate fixedly disposed at the output end of the telescopic cylinder. The label suction plate is positioned corresponding to the material-taking groove. The label suction plate is fixedly connected to the piston rod of the telescopic cylinder. The label suction plate is provided with multiple negative pressure suction cups and two air blowing ports, which are respectively disposed on both sides of the label suction plate.

[0014] Furthermore, the driving mechanism includes a first transverse mechanism and a second transverse mechanism disposed on the first transverse mechanism, the mold frame is fixedly disposed on the second transverse mechanism, and the moving direction of the second transverse mechanism is arranged perpendicular to the moving direction of the first transverse mechanism.

[0015] Furthermore, both the first brush and the second brush are bristle brushes.

[0016] By adopting the aforementioned design scheme, the beneficial effects of this utility model are:

[0017] By setting a longitudinal movement mechanism and a label brushing assembly on the label storage bracket, and setting a first label brush and a second label brush on the label brushing assembly, the three-dimensional labeling device for square boxes of this utility model can automatically label square boxes. It has high working efficiency, reliable structure, good stability, and good market promotion prospects.

[0018] Furthermore, the label suction plate is also equipped with two air inlets, which are located on both sides of the label suction plate. This allows the label to be more easily adsorbed by the air channels on the side of the square box, thus sticking tightly to the side of the square box and making it easy for the label to be quickly and firmly attached to the square box.

[0046] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0047] like Figures 1 to 5 As shown, an automatic three-dimensional labeling device for square boxes includes a label bin 11 for placing labels 10, a label bin support 1 for placing the label bin 11, and a mold rack 2 for placing square boxes 20. The label bin support 1 is provided with a label-picking mechanism 30 for picking up the labels 10 from the label bin 11 and placing them on the square boxes 20. The label bin support 1 and the mold rack 2 are arranged opposite to each other. The label-picking mechanism 30 is arranged on the label bin support 1 and is located between the mold rack 2 and the label bin support 1. In actual use, multiple square boxes 20 can be arranged at intervals on the mold rack 2 according to production needs, and a corresponding number of label bins 11 and label-picking mechanisms 30 can be arranged on the label bin support 1. Specifically, in this utility model, two square boxes 20 are arranged on the mold rack 2, and the two square boxes 20 are arranged vertically at intervals. Correspondingly, two label bins 11 and label-picking mechanisms 30 are arranged vertically at intervals on the label bin support 1 corresponding to the positions of the square boxes 20.

[0048] It should be noted that the square box 20 of this utility model is specifically a square mold. In order to facilitate the label 10 to be adsorbed on the square box 20, air passages 21 are provided in the middle and four sides of the square box 20. The air passages 21 are connected to an external vacuum device (not shown in the figure). Correspondingly, the mold frame 2 is provided with slots for the air passages 21 to be connected to the external vacuum device at the position corresponding to the square box 20. With this configuration, when the label taking mechanism 30 places the label 10 on the square box 20, the vacuum device can be activated so that the label 10 can be adsorbed on the square box 20.

[0049] The labeling device of this utility model also includes a drive mechanism 3 for driving the mold frame 2 to move horizontally, a longitudinal movement mechanism 4 disposed on one side of the label holder 1, and label brushing components 5 disposed on the longitudinal movement mechanism 4. The number of label brushing components 5 needs to correspond to the number of label taking mechanisms 30. Accordingly, this utility model has two sets of label brushing components 5 arranged vertically at intervals, such as... Figure 1 As shown, with one side of the mold frame 2 as the left side and one side of the standard compartment support 1 as the right side, the side of the standard compartment support 1 closer to the longitudinal movement mechanism 4 is the front side, and the side of the standard compartment support 1 away from the longitudinal movement mechanism 4 is the rear side. The driving mechanism 3 includes a first transverse movement mechanism 31 that moves in the front-back direction and a second transverse movement mechanism 32 disposed on the first transverse movement mechanism 31. The mold frame 2 is fixedly disposed on the second transverse movement mechanism 32, and the movement direction of the second transverse movement mechanism 32 is the left-right direction. Figure 1 As shown, the first transverse mechanism 31 is supported and fixed by the support frame at the bottom.

[0050] The first transverse mechanism 31 includes a first slide rail 311 arranged in the front-back direction, a first slide block 312 that can slide on the first slide rail 311, and a first drive motor 313 that drives the first slide block 312 to slide. The second transverse mechanism 32 is fixedly mounted on the first slide block 312 via a fixed seat 33. The second transverse mechanism 32 includes a second slide rail 321 arranged in the left-right direction, a second slide block 322 that can slide on the second slide rail 321, and a second drive motor 323 that drives the second slide block 322 to slide. A fixed plate 324 arranged in the front-back direction is provided on the second slide block 322. The mold frame 2 is fixedly mounted on the fixed plate 324. It should be noted that in this utility model, the driving connection method of the first drive motor 313 and the first slide block 312 and the driving connection method of the second drive motor 323 and the second slide block 322 are all conventional methods in the art. As long as the above effects can be achieved, it is acceptable. For example, a gear belt transmission mechanism can be used for transmission connection. For ease of understanding, the first drive motor 313 is used as an example. Figure 1 and Figure 2 As shown, the output end of the first drive motor 313 is located at the bottom of the first slide rail 311. Gears are provided between the output end of the first drive motor 313 and the first slide rail 311, and the gears are connected by a belt. The first slide block 312 is fixed on the belt, so that the first drive motor 313 can drive the first slide block 312 to move. Other conventional methods will not be described in detail in this embodiment.

[0051] The longitudinal movement mechanism 4 includes a third slide rail 41 mounted on the label holder 1, a third slide block 42 that can slide on the third slide rail 41, and a third drive motor (not shown in the figure) that drives the third slide block 42. Correspondingly, the third slide rail 41 is arranged longitudinally, and the label brushing assembly 5 is fixed on the third slide block 42. The label brushing assembly 5 includes a connecting rod 51 arranged in the left-right direction and a label brushing part 52 fixed at the end of the connecting rod 51 away from the longitudinal movement mechanism 4. The label brushing part 52 is located on the moving path of the mold frame 2 and behind the label taking mechanism 30. In this invention, the label brushing part 52 has a U-shaped structure. A groove 53 adapted to the size of the square box 20 is provided on one side facing the mold frame 2. Two first brush marks 54 arranged in opposite directions are fixed on the two opposite side walls of the groove 53. A space for the square box 20 to extend into is formed between the two first brush marks 54. A second brush mark 55 facing upward is fixed on the top of the front side of the brush mark part 52. It should be noted that in this embodiment, the first brush mark 54 and the second brush mark 55 are preferably brushes. The brush head is soft and has elasticity. In actual use, plastic paper or conventional materials with the same function in the art, such as plastic cardboard, can also be used.

[0052] Specifically, the label storage compartment 11 of this utility model includes a base 12 mounted on a label storage bracket 1 and a storage module mounted on the base 12 for storing labels 10. The storage module is fixed to the base 12 at an upward angle. A material retrieval slot 13 is provided on the base 12 corresponding to the position of the storage module. The material retrieval slot 13 penetrates both ends of the base 12. The base 12 is also provided with several discharge baffles 14 arranged around the edge of the material retrieval slot 13 to prevent the labels 10 from falling out of the material retrieval slot 13. The material retrieval slot 13 can be set according to the shape of the labels 10. Specifically, the storage module includes several positioning rods 15 arranged around the material retrieval slot 13, and one end of each positioning rod 15 is fixedly connected to the base 12. The other end of each positioning rod 15 is provided with a limiting plate 16. The storage module is inclined upward, so that the labels 10 are tilted towards the base 12 due to their own weight. The downward sliding trend means that when one label 10 is removed, the next label 10 will slide down to replace the position of the previous label 10. Automatic and stable label 10 feeding can be achieved without electric drive, saving production costs and improving operational efficiency. Preferably, the storage module is also equipped with a pushing mechanism, which includes several guide posts 17 arranged parallel to the positioning rod 15 and a pushing plate 18 sleeved on the guide posts 17. The pushing plate 18 is located diagonally above the label 10. The two ends of the guide posts 17 are fixed to the base 12 and the limiting plate 16, respectively. The pushing plate 18 is set corresponding to the picking slot 13. This arrangement ensures that the pushing plate 18 is always diagonally above the label 10, and can exert a squeezing effect on the label 10 under its own weight, causing the label 10 to always move closer to the picking slot 13, facilitating the label picking mechanism 30 to pick up the label.

[0053] The label-taking mechanism 30 includes a rotatable rotating spindle 301 mounted on the label holder 1 and a label-taking fixture 6 mounted on the rotating spindle 301. The label-taking fixture 6 is positioned corresponding to the material chute 13. The rotating spindle 301 is arranged in a front-to-back direction and is driven by a motor 302. The label-taking fixture 6 includes a telescopic cylinder 61 fixedly mounted on the rotating spindle 301 and a label suction plate 62 fixedly mounted on the output end of the telescopic cylinder 61. The label suction plate 62 is positioned corresponding to the material chute 13 and is fixedly connected to the piston rod of the telescopic cylinder 61. The label suction plate 62 is provided with multiple negative pressure suction cups 63 for picking up the labels 10. The labels 10 blocked by the discharge baffle 14 are picked up by the multiple negative pressure suction cups 63 on the label suction plate 62. Due to the softness of the labels 10, they can be removed.

[0054] like Figures 2 to 5As shown, before the labeling device of this utility model operates, the third slide 42 on the longitudinal movement mechanism 4 moves upward, so that the horizontal position of the label brushing part 52 is higher than the horizontal position of the corresponding square box 20, and the position of the groove 53 of the label brushing part 52 and the position where the label picking mechanism 30 places the label 10 are both on the moving path of the square box 20. During operation, the first transverse movement mechanism 31 first moves the square box 20 on the mold frame 2 to the left side of the label compartment 11 corresponding to the position of the label picking mechanism 30, and the negative pressure suction cup 63 on the label suction plate 62 picks up the label. After label 10 is picked up, the main shaft 301 rotates and places the picked-up label 10 on the upper side of the square box 20. At this time, label 10 is placed on the upper side of the square box 20 and is attracted by the air passage 21. The two ends of label 10 are attached to the square box 20 under their own weight. The first transverse mechanism 31 then controls the mold frame 2 to move to the position of the label brush assembly 5. At this time, the second transverse mechanism 32 can control the square box 20 with label 10 to be located directly below the groove 53 of the label brush part 52. The third slide 42 on mechanism 4 moves downward, causing the two first brush labels 54 in the groove 53 to move both ends of the label 10 downward, so that both ends of the label 10 are pressed against the square box 20 along the front and back sides of the square box 20. When the third slide 42 moves downward so that the top of the second brush label 55 is at the bottom of the square box 20, the third slide 42 stops moving, and the first transverse mechanism 31 then controls the mold frame 2 to move forward. The end of the label 10 corresponding to the lower side of the square box 20 is blocked by the second brush label 55. Thus, under the action of the second labeling component 55, the labeling work is completed by closely adhering to the lower side of the square box 20. Afterwards, the first transverse mechanism 31 continues to transport the mold frame 2 forward, so that the square box 20 is away from the labeling component, and removes the square box 20 from the mold frame 2 and replaces it with a new batch of unlabeled square boxes 20. The third slide 42 moves upward to reset the labeling component 5. After the labeling component 5 is reset, the first transverse mechanism 31 drives the new unlabeled square box 20 to reset and repeats the above operation to realize the automatic reciprocating labeling work.

[0055] Preferably, in order to facilitate the label 10 to be quickly and tightly attached to the square box 20, the label suction plate 62 is also provided with two air blowing ports 621. The two air blowing ports 621 are respectively located on both sides of the label suction plate 62 and connected to external compressed gas (not shown in the figure). It should be noted that when the square box 20 moves to the label taking mechanism 30, it is in the labeling position. The positions of the two air blowing ports 621 correspond to the positions of the square box 20 when it is in the labeling position. This allows the label 10 to be blown down by both ends through the air blowing ports 621 when the square box 20 is at the bottom of the label suction plate 62. This makes it easier for the label 10 to be adsorbed by the air passages 21 on the side of the square box 20, thereby sticking tightly to the side of the square box 20.

[0056] By setting a longitudinal movement mechanism 4 and a label brushing assembly 5 on the label storage bracket, and setting a first label brush 54 and a second label brush 55 on the label brushing assembly 5, the three-dimensional labeling device for square boxes of this utility model can automatically label square boxes 20. It has high working efficiency, reliable structure, good stability, and good market promotion prospects.

[0057] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
