Description

Technical Field

[0001] This utility model relates to the technical field of cardboard box production equipment, specifically a corrugated cardboard box labeling device. Background Technology

[0002] Corrugated cardboard box labeling devices are specialized equipment for applying labels to corrugated cardboard boxes. In industries such as packaging, logistics, food, and pharmaceuticals, corrugated cardboard boxes are a primary packaging material with huge demand. To improve production efficiency, reduce labor costs, and ensure the accuracy and consistency of label application, corrugated cardboard box labeling devices have emerged. With the continuous development of automation technology, corrugated cardboard box labeling devices have gradually achieved automation and intelligence. These devices are typically equipped with high-precision sensors and intelligent control systems, capable of automatically completing operations such as label positioning, application, and clamping. Furthermore, to adapt to cardboard boxes of different sizes and shapes, as well as different types of labels, corrugated cardboard box labeling devices also possess high flexibility and adaptability. With the rapid development of e-commerce and logistics industries, the demand for corrugated cardboard boxes continues to grow. At the same time, consumers' requirements for product quality and packaging are also increasing, prompting corrugated cardboard box labeling devices to continuously develop towards greater efficiency, intelligence, and environmental friendliness.

[0003] A search revealed that the patent document (authorization announcement number CN218907926U) includes a device housing, a threaded rod, and a guide plate. A partition is fixedly connected inside the device housing, and a first connecting frame is fixedly connected to the top surface of the partition. A take-up and release wheel is rotatably connected to the first connecting frame. This corrugated carton labeling device is equipped with a guide plate. Workers place the corrugated carton on a conveyor belt and activate a second motor next to the support column, driving a rotating shaft and wheels to rotate. The wheels drive the conveyor belt, transporting the carton into the device. The guide plate then supports and straightens the carton, preventing misalignment. If the carton is too large or too small, the threaded rod can be used to adjust the contact between the guide plate and the carton. Activating a first motor next to the first connecting frame on one side pulls the labeling mechanism. The label is spread open by a transmission wheel on the second connecting frame, preventing tilting and misalignment, significantly reducing rework rates and improving production efficiency.

[0004] However, the above-mentioned device still has shortcomings:

[0005] During operation, some debris often gets stuck on the conveyor belt. This debris will stick to the cardboard boxes, thus contaminating their appearance and indirectly affecting their quality. Utility Model Content

[0027] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] like Figure 1-5 As shown, a corrugated cardboard box labeling device includes a workbench 1, a plurality of bottom supports 101 are fixedly connected to the bottom of the workbench 1, and abutment supports 102 are fixedly connected to the side walls of the bottom supports 101.

[0029] A conveyor belt 402 is installed above the workbench 1. A protective shell 2 is fixedly connected to the top of the workbench 1. An inlet 201 is opened on one side of the protective shell 2, and an outlet 202 is opened on the other side of the protective shell 2. The conveyor belt 402 is installed inside the protective shell 2.

[0030] A protective block 7 is fixedly connected to the top of the workbench 1. A scraper 701 is slidably connected inside the protective block 7. A spring 702 is installed inside the scraper 701. The two ends of the spring 702 are fixedly connected to the protective block 7 and the scraper 701 respectively. The scraper 701 is located below the spring 702. The top of the scraper 701 is sharp. The top of the protective block 7 abuts against the conveyor belt 402.

[0031] The protective block 7 and the scraper 701 are designed so that the scraper 701 can contact the surface of the conveyor belt 402 when the conveyor belt 402 is in motion. The contact of the scraper 701 can effectively scrape away the stains on the surface of the conveyor belt 402, thereby cleaning the surface of the conveyor belt 402 and preventing the stains on the conveyor belt 402 from sticking to the box 3, thus ensuring the overall aesthetics of the box 3.

[0032] In this embodiment, specifically, a vertical plate 4 is fixedly connected to the top of the workbench 1, a drive shaft 401 is rotatably connected to the side wall of the vertical plate 4, and a conveyor belt 402 is sleeved on the outside of the drive shaft 401.

[0033] In this embodiment, specifically, a box 3 is provided above the workbench 1, the box 3 is located inside the protective shell 2, the box 3 is located above the conveyor belt 402, and a pair of uprights 6 are fixedly connected to the top of the workbench 1, and an electric push rod 601 is fixedly connected to one end of the pair of uprights 6 that is close to each other.

[0034] During the marking operation, the movement of the electric push rod 601 effectively fixes the housing 3, preventing it from shifting during marking and thus ensuring the marking is done in the correct position. This significantly reduces the number of defective products, improves work efficiency, and minimizes losses.

[0035] In this embodiment, specifically, an electric telescopic rod 5 is fixedly connected to the top of the protective shell 2, a marking device 501 is fixedly connected to the bottom of the electric telescopic rod 5, and an air vent 502 is fixedly connected to the top of the protective shell 2. The air vent 502 is located above the conveyor belt 402.

[0036] The air vent 502 is designed so that the air blown out of the air vent 502 can be directly sprayed onto the surface of the conveyor belt 402, thereby cleaning the surface of the conveyor belt 402 by means of air force. Secondly, as the conveyor belt 402 moves, the box 3 set on the conveyor belt 402 will also come into contact with the air force, thereby cleaning the area on the top of the box 3 that needs to be marked, so as to avoid the dust affecting the final marking result during the marking process.

[0037] In this embodiment, specifically, the end of the electric push rod 601 away from the upright rod 6 is in contact with the housing 3.

[0038] In this embodiment, the marking device 501 is specifically positioned above the conveyor belt 402.

[0039] Working principle: When the conveyor belt 402 is in motion, the box 3 is first placed on the conveyor belt 402. The scraper 701 can contact the surface of the conveyor belt 402. Through the contact of the scraper 701, the dirt on the surface of the conveyor belt 402 can be effectively scraped off, thereby cleaning the surface of the conveyor belt 402 and preventing the dirt on the conveyor belt 402 from sticking to the box 3, thus ensuring the overall aesthetics of the box 3.

[0040] During the marking operation, the movement of the electric push rod 601 can fix the box 3, effectively preventing the box 3 from shifting during marking, which would prevent the marking from being done in the designated position and greatly reduce the occurrence of defective products.

[0041] The air blown out of the air vent 502 can directly spray onto the surface of the conveyor belt 402, thereby cleaning the surface of the conveyor belt 402 through the air force. Secondly, as the conveyor belt 402 moves, the box 3 set on the conveyor belt 402 will also come into contact with the air force, thereby cleaning the area on the top of the box 3 that needs to be marked, so as to avoid the dust affecting the final marking result during the marking process.

[0042] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
