Description

Technical Field

[0001] This utility model relates to the field of automatic box labeling machine technology, specifically an automatic box labeling machine. Background Technology

[0002] Automatic box labeling machines are mainly used to print or affix "box label" information on the surface of outer packaging boxes (such as cardboard boxes, wooden boxes, etc.) for warehousing management, logistics transportation, customs inspection and sales traceability. By using automation, they can quickly print or affix box label information, significantly improving labeling efficiency and accuracy, and have become an important piece of equipment in modern packaging production lines.

[0003] However, in practical applications, existing automatic box label printing machines still have certain limitations: to ensure the clarity and accuracy of the printed or pasted box label information, the equipment often needs to pause the box during the printing process or significantly reduce the conveying speed to match the printing action. This pause or speed reduction will disrupt the continuous flow rhythm of the production line, resulting in limited overall printing efficiency. This problem is even more prominent in scenarios with high production capacity requirements. Therefore, how to reduce or eliminate the pauses caused by the printing operation while ensuring the quality of box label markings (clarity and accuracy) and improve the continuous operation efficiency of automatic box label printing machines has become a technical problem that urgently needs to be solved in this field.

[0004] Therefore, this utility model provides an automatic box label making machine. Utility Model Content

Each conveying mechanism includes two drive shafts and a conveyor belt. The conveyor belt moves horizontally between the corresponding two drive shafts. The upper conveyor belt is equipped with several coding units, and the box is placed on the lower conveyor belt. The lower conveyor belt is equipped with two strip-shaped protrusions and several push rods. The two strip-shaped protrusions are symmetrically distributed, and the push rods are equidistantly distributed. Each push rod is equipped with a first positioning sensor. The upper conveyor belt is equipped with several second positioning sensors, and the first and second positioning sensors are wirelessly connected.

[0020] 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.

[0021] Please see Figure 1-4 An automatic box labeling machine includes a support frame 1, and two conveying mechanisms 2 are arranged inside the support frame 1. The conveying mechanism 2 includes two drive shafts 21 and a conveyor belt 22.

[0022] The conveyor belt 22 moves horizontally between the two corresponding drive shafts 21. Several coding units 24 are set on the upper conveyor belt 22, and the box is placed on the lower conveyor belt 22.

[0023] It should be noted that, in this embodiment, the box and the coding unit 24 move horizontally together between the two conveying mechanisms 2 to achieve the coding of the box label during movement.

[0024] The lower conveyor belt 22 is equipped with two strip-shaped protrusions 23 and several push rods 25. The two strip-shaped protrusions 23 are symmetrically distributed, and the push rods 25 are equidistantly distributed.

[0025] It should be noted that the strip-shaped protrusion 23 and the push rod 25 described in this embodiment limit the box body, and the push rod 25 pushes the box body.

[0026] Each of the push rods 25 is equipped with a first positioning sensor 26, and the upper conveyor belt 22 is equipped with a number of second positioning sensors 27. The first positioning sensors 26 and the second positioning sensors 27 are wirelessly connected.

[0027] It should be noted that, in this embodiment, the first positioning sensor 26 and the second positioning sensor 27 sense each other when they are aligned, thereby aligning the coding unit 24 with the box.

[0028] Specifically, the two conveying mechanisms 2 inside the support frame 1 drive the conveyor belt 22 to move horizontally synchronously via the drive shaft 21. The box is placed on the lower conveyor belt 22, and its two sides are limited by symmetrically distributed strip-shaped protrusions 23 to ensure stable conveying direction. Several equally spaced push rods 25 push the box to move synchronously with the lower conveyor belt 22. The coding unit 24 on the upper conveyor belt 22 moves synchronously with the upper conveyor belt 22. When the first positioning sensor 26 on the lower push rod 25 and the second positioning sensor 27 on the upper conveyor belt 22 move to the alignment position, they achieve precise alignment through wireless sensing. At this time, the coding unit 24, while moving synchronously with the box, marks the box. The box marking operation is performed on the surface of the box. Throughout the process, the box and the marking unit 24 move horizontally with the conveyor belt 22 without stopping or slowing down. The dynamic synchronization between the marking unit 24 and the box is achieved by the synchronous movement of the upper and lower conveyor belts 22. The alignment sensing of the first positioning sensor 26 and the second positioning sensor 27 ensures the accuracy of marking. This not only solves the problem of low efficiency caused by the stop or slowdown of traditional equipment, but also ensures stable delivery of the box through the limiting and pushing action of the strip protrusion 23 and the push rod 25. While ensuring the clarity and accuracy of the box marking, continuous and uninterrupted box marking operation is achieved, improving the overall operation efficiency. It is especially suitable for high-capacity demand scenarios.

[0029] In one embodiment of this utility model, such as Figures 1-4 As shown, the push rod 25 has a groove 251 on the side near the box body, and a material sensing unit 252 that contacts the box body is installed in the groove 251.

[0030] It should be noted that the push rod 25 described in this embodiment senses the position of the box through the material sensing unit 252.

[0031] Specifically, a material sensing unit 252 is installed in the groove 251 on the side of the push rod 25 near the box. When the push rod 25 moves with the conveyor belt 22 and contacts the box, the material sensing unit 252 senses the position of the box in real time. The box and the push rod 25 maintain stable contact and feed the signal back to the control system to accurately control the start time and position of the coding unit 24, which facilitates the subsequent coding work on the box.

[0032] In one embodiment of this utility model, such as Figures 1-4 As shown, two drive mechanisms 11 are installed on one side of the support frame 1, and the two drive mechanisms 11 drive the upper and lower transmission shafts 21 respectively.

[0033] It should be noted that the output end of the drive mechanism 11 described in this embodiment is connected to the end of the corresponding transmission shaft 21.

[0034] Specifically, the two drive mechanisms 11 on one side of the support frame 1 are respectively connected to the ends of the upper and lower transmission shafts 21, and independently drive the upper and lower conveyor belts 22 to run. The speed and start and stop timing of the two are precisely synchronized by the control system. After the material sensing unit 252, the first positioning sensor 26 and the second positioning sensor 27 complete the positioning work, the coding unit 24 starts the coding work, ensuring that the coding unit 24 and the box remain relatively stationary in the coding area. This avoids the speed error caused by load difference in the traditional single drive system, and realizes high-precision synchronous movement between the coding unit 24 and the box. Clear coding can be completed without stopping, which improves the efficiency of continuous operation and the quality of marking.

[0035] In one embodiment of this utility model, such as Figures 1-4 As shown, both sides of the two conveying mechanisms 2 are provided with synchronous transmission belts 28, and the two horizontally corresponding transmission shafts 21 rotate synchronously through the corresponding two synchronous transmission belts 28.

[0036] It should be noted that there is a gap between the synchronous transmission belt 28 and the support frame 1 described in this embodiment.

[0037] Specifically, the synchronous transmission belts 28 on both sides of the two transmission mechanisms 2 are respectively connected to the horizontally corresponding transmission shafts 21. When the transmission shafts 21 rotate under the drive mechanism 11, the synchronous transmission belts 28 ensure that the two horizontally corresponding transmission shafts 21 maintain completely consistent speed and direction through meshing transmission, ensuring the stable operation of the transmission mechanism 2. The gap between the synchronous transmission belts 28 and the support frame 1 avoids friction interference during movement.

[0038] In one embodiment of this utility model, such as Figures 1-4 As shown, an extension frame 12 is installed at one end of the support frame 1, and a quality inspection unit 13 is set below the extension frame 12.

[0039] It should be noted that the quality inspection unit 13 described in this embodiment is an industrial camera, which detects whether the box label on the box is standard.

[0040] Specifically, a quality inspection unit 13, which serves as an industrial camera, is installed below the extension frame 12 mounted at one end of the support frame 1. When the box with the box label is completed is transported to the extension frame 12 by the conveyor belt 22 below, the quality inspection unit 13 acquires images of the box label on the box and identifies whether the clarity, positional deviation, and barcode / QR code recognizability of the box label meet the standards through the built-in algorithm, and feeds the inspection results back to the control system.

[0041] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0042] Working principle: Two conveying mechanisms 2 inside the support frame 1 drive the conveyor belt 22 through the drive shaft 21. Two drive mechanisms 11 on one side of the support frame 1 are connected to the ends of the upper and lower drive shafts 21 respectively to independently drive the upper and lower conveyor belts 22. Synchronous drive belts 28 on both sides of the two conveying mechanisms 2 are connected to the horizontally corresponding drive shafts 21 respectively, ensuring that the two horizontally corresponding drive shafts 21 maintain completely consistent speed and direction, so that the upper and lower conveyor belts 22 move horizontally synchronously. The box is placed on the lower conveyor belt 22, and its sides are limited by symmetrically distributed strip-shaped protrusions 23. Several equidistantly distributed push rods 25 push the box to move synchronously with the lower conveyor belt 22. The push rods 25 are located near the groove 251 on the side of the box. The material sensing unit 252 inside contacts the box and senses the position of the box; the coding unit 24 on the upper conveyor belt 22 moves synchronously with the upper conveyor belt 22. When the first positioning sensor 26 on the push rod 25 aligns with the second positioning sensor 27 on the upper conveyor belt 22 and wirelessly senses, the coding unit 24 performs the box labeling operation on the surface of the box while maintaining relative stillness with the box; when the box with the box label completed is transported by the lower conveyor belt 22 to the lower end of the support frame 1 extension frame 12, the quality inspection unit 13 performs image acquisition on the box label and detects whether it meets the standard. Throughout the process, the box and the coding unit 24 always move horizontally with the conveyor belt 22 without stopping or slowing down, realizing continuous and efficient box labeling.
