Description

Technical Field

[0001] This utility model relates to the field of packaging box processing, and more specifically, it relates to a packaging box labeling machine. Background Technology

[0002] With the rapid development of my country's packaging industry, the use and demand for labeling machines are becoming increasingly widespread, leading to the emergence of various labeling machines on the market. However, regardless of whether it's a flat labeling machine, side labeling machine, double-sided labeling machine, or circumferential labeling machine, they all use a single labeling head, meaning they can only apply one label at a time. To apply multiple labels to an object simultaneously, the labeling is usually done on an unfolded flat piece of paper. After labeling, the paper is folded into a box. However, this process involves multiple labeling passes, which is not only cumbersome and inefficient, but also requires bottom labeling and flipping of the packaging box for labeling. Furthermore, the back-and-forth labeling and flipping process can easily introduce labeling errors, affecting labeling accuracy and making it difficult to guarantee product quality. Therefore, applying multiple labels to an object is a major challenge for manufacturing companies.

[0003] The prior art discloses a double-sided labeling machine for packaging boxes, with publication number CN211568524U. It uses a first labeling machine and a bottom labeling machine to perform multiple double-sided labeling operations on the packaging box through its own labeling tray, pressure roller, and labeling head.

[0004] With increasingly higher demands for work efficiency, double-sided labeling is becoming increasingly inadequate for the needs of current production lines. Therefore, it is necessary to develop a labeling machine that can optionally label all four sides of packaging boxes. Utility Model Content

[0026] Reference Figures 1 to 5 As shown, in order to achieve the above objectives, the present invention provides the following technical solution: a packaging box labeling machine, including a workbench 1, a conveyor chain 2, a mounting frame 3 and a labeling module. The workbench 1 is provided with a conveying area 11, and the conveyor chains 2 are respectively arranged on both sides of the conveying area 11. The two conveyor chains 2 are moved synchronously through a synchronization mechanism.

[0027] The mounting frame 3 can be detachably installed on the conveyor chain 2, and the mounting frame 3 is used for placing packaging boxes.

[0028] The labeling module is set up with four groups, namely the left labeling module 4, the right labeling module 5, the upper labeling module 6, and the lower labeling module 7. The workbench 1 is set with a labeling area. The left labeling module 4 and the right labeling module 5 are respectively movably installed on both sides of the labeling area in the width direction. The upper labeling module 6 is movably installed on the upper side of the labeling area in the height direction. The lower labeling module 7 is set on the lower side of the labeling area in the height direction.

[0029] The design of this utility model uses a conveyor chain 2 to directionally transport the packaging box, so that the packaging box passes through the labeling area in sequence. The left labeling module 4, right labeling module 5, upper labeling module 6 and lower labeling module 7 respectively perform labeling operations on the four sides of the packaging box. Furthermore, the labeling requirements of packaging boxes of different sizes can be met by adjusting the positions of the left labeling module 4, right labeling module 5 and upper labeling module 6.

[0030] The synchronization mechanism is existing technology and can be a synchronization rod and synchronization gear that can cooperate with the conveyor chain 2, as well as a transmission motor. Two sets of synchronization gears are provided at both ends of the conveyor chain 2. The synchronization gears achieve synchronous transmission through the synchronization rod. The transmission motor is connected to a synchronization gear and is used to drive the integrated conveyor mechanism to achieve directional conveying.

[0031] Note that, Figure 1 The conveyor chain 2 in the text is only a part of the chain.

[0032] The present invention is further configured such that: connecting plates 21 are provided on both sides of the conveyor chain 2 along its length direction, the connecting plates 21 are arranged in an L-shape, and the connecting plates 21 are provided with connecting holes 22 for connecting with the mounting frame 3. This structural design can facilitate the installation of the mounting frame 3 and the connecting plates 21.

[0033] This utility model is further configured such that: the mounting bracket 3 includes a first mounting plate 31 and a second mounting plate 32, both of which can be detachably mounted on the connecting plate 21. This structural design, as... Figure 3 As shown, the first mounting plate 31 and the second mounting plate 32 can be arranged in a U-shape and are used to partially surround the packaging box. By installing the first mounting plate 31 and the second mounting plate 32 of different specifications onto the connecting plate 21 at different positions, areas with different enclosure ranges can be formed for placing packaging boxes of different specifications.

[0034] Both the first mounting plate 31 and the second mounting plate 32 are provided with mounting holes corresponding to the connecting hole 22. After the two are aligned, they can be tightened with bolts.

[0035] The present invention is further configured such that the upper labeling module 6 and the lower labeling module 7 are arranged sequentially along the conveying direction of the conveyor chain 2.

[0036] The present invention is further configured such that: both the left labeling module 4 and the right labeling module 5 include a movable plate 41 and an adjustment component 42; a sliding groove is provided on the workbench 1; and a sliding block 411 is provided at the lower end of the movable plate 41 and is slidably connected to the sliding groove.

[0037] The adjustment component 42 is linked with the sliding block 411.

[0038] The present invention is further configured such that: the adjustment component 42 includes an adjustment screw 421 and a guide rod 422, the adjustment screw 421 is rotatably connected in the sliding groove and one end extends out from one side of the workbench 1, the guide rod 422 is fixedly installed in the sliding groove, and the sliding block 411 is provided with a threaded hole and a guide hole.

[0039] The design of this structure allows the sliding block 411 to move along the length of the guide rod 422 by rotating the adjusting screw 421, thereby changing the spacing between the left labeling module 4 and the right labeling module 5 to accommodate labeling operations for packaging boxes of different widths.

[0040] like Figure 5 As shown, the installation positions of the adjusting screw 421 and the guide rod 422 require certain considerations: 1. They need to avoid the position of the drive motor 55 to prevent interference during movement; 2. If necessary, in order to ensure the stable movement of the sliding block 411, two sets of guide rods 422 can be provided.

[0041] The present invention is further configured such that: the upper labeling module 6 includes a lifting frame 61, a lifting plate 62, and a lifting bolt 63. The lifting plate 62 is slidably connected to the lifting frame 61, and the lifting bolt 63 is rotatably connected to the upper end of the lifting frame 61 and connected to the lifting plate 62.

[0042] The structure is designed so that by rotating the lifting bolt 63, the lifting bolt 63 rotates and engages with the upper end of the lifting frame 61 (which has a threaded connection hole 22 at the upper end), thereby driving the lifting plate 62 to move up and down.

[0043] The lifting bolt 63 and the lifting plate 62 are circumferentially rotating and axially fixed (that is, both the lifting plate 62 and the lifting bolt 63 are provided with mutually cooperating connecting blocks and connecting grooves, and both the connecting blocks and connecting grooves are convex structures).

[0044] The adjustment method can be as follows: place the packaging box in the labeling area, and then gradually move the peeling plate closer to the packaging box by rotating the lifting bolt and adjusting screw until the position is correct.

[0045] The present invention is further configured such that: the left labeling module 4, the right labeling module 5, the upper labeling module 6 and the lower labeling module 7 each include a labeling mechanism 51, a backing paper receiving mechanism 52, a peeling plate 53, a paper pressing mechanism 54 and a drive motor 55, and the drive motor 55 is connected to the paper pressing mechanism 54.

[0046] This structure is designed using existing technology, such as Figure 1 and Figure 4 The illustration is shown as only one implementation method for achieving the labeling operation.

[0047] The present invention is further configured such that a controller 8 is provided on the workbench 1.
