Description

Technical Field

[0001] The utility model relates to the technical field of vegetable packaging, in particular to an automatic labeling device for vegetable packaging. Background Art

[0002] Vegetables are a favorite side dish for people of all ethnic groups in my country. They are highly sought after due to their unique flavors, such as sweet, crisp, tender, salty, savory, and spicy, as well as their nutritional value. Vegetables are typically packaged in boxes for easy transportation. These boxes are often transported on conveyor belts, requiring labels to be attached during transportation.

[0003] However, when the conveying speed is too fast, the conveying speed of the vegetable packaging box will become faster, which will cause the manual labeling to be accelerated. There will be cases of missing labels in this process. Therefore, an automatic vegetable packaging labeling device is needed to solve the above problem. Utility Model Content

[0004] The utility model aims to provide an automatic labeling device for vegetable packaging, which has the advantage of improving labeling efficiency and solving the problem of low efficiency and easy omission of labeling in manual labeling.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: an automatic labeling device for vegetable packaging, comprising a base frame, wherein a driving roller and a driven roller are rotatably mounted on the front and rear ends of the top of the base frame, respectively, the driving roller and the driven roller are connected by a conveyor belt transmission, a first winding roller and a second winding roller are provided above the driven roller via a connecting frame, the first winding roller and the second winding roller are connected by a label laminating transmission, and further comprising a transmission mechanism, a first guide roller and a second guide roller;

[0006] The first guide roller and the second guide roller are both arranged on the opposite side of the driven roller and the second winding roller;

[0007] Wherein, the first guide roller and the second guide roller are rotatably connected via a second positioning frame;

[0008] Wherein, the first positioning frame is installed on the top of the second positioning frame by adjusting the spring elasticity;

[0009] Wherein, the first winding roller and the second winding roller are rotatably connected via a first positioning frame;

[0010] The transmission mechanism is arranged at the front and rear ends of the driven roller;

[0011] The driven roller is connected to the second winding roller via a transmission mechanism.

[0012] When using an automatic labeling device for vegetable packaging in the present technical solution, the transmission roller starts to rotate through the driving mechanism and drives the driven roller to operate through the conveyor belt. The vegetable packaging box is directly placed on the conveyor belt close to the transmission roller. As the conveyor belt moves into the working area of ​​the device, one end of the label film is wound around the first winding roller and the other end is wound around the second winding roller, and the label film passes under the first guide roller and the second guide roller, ready to contact the vegetable packaging box. As the vegetable packaging box moves on the conveyor belt, the label film is guided to the top of the packaging box, and when passing through the first guide roller and the second guide roller, the label film is parallel to the upper surface of the packaging box. When the vegetable packaging box passes under the label film, the label is attached to the vegetable packaging box. During this process, the tension and position of the label coating are controlled by adjusting the spring and the first positioning frame to ensure that the label is flat and accurately attached to the packaging box. The driven roller is connected to the second winding roller through a transmission mechanism to ensure that the tension and speed of the label during the attachment process match the moving speed of the conveyor belt. The vegetable packaging box continues to move on the conveyor belt, and the label is completely attached to the packaging box, completing the automatic labeling process. The labeled vegetable packaging box continues to move through the conveyor belt and is finally output from the other end of the device, completing the entire packaging process.

[0013] Preferably, a driving mechanism is installed at the front end or the rear end of the transmission roller.

[0014] By installing the drive mechanism at the front or rear end of the transmission roller, a more flexible drive mode can be achieved. This design can select the drive position according to actual needs, thereby optimizing the transmission efficiency and control mode. For example, if the drive mechanism is installed at the front end, the start and stop of the conveyor belt can be controlled more directly, improving the response speed.

[0015] Preferably, the size of the driven roller matches the size of the second winding roller.

[0016] By ensuring that the size of the driven roller matches that of the second winding roller, synchronization and stability between the conveyor belt and the label film can be maintained. This design helps reduce friction and wear caused by size mismatch, extending equipment life while improving label film attachment accuracy.

[0017] Preferably, one end of the label film is wound around the first winding roller, and the other end of the label film is wound around the second winding roller, and the label film passes under the first guide roller and the second guide roller.

[0018] This design creates a stable tension between the first and second winding rollers for the label film. The first and second guide rollers guide the film, ensuring smoothness and accuracy during the label application process. This helps improve label application quality and reduces wrinkles and bubbles.

[0019] Preferably, the label films on the opposite sides of the first guide roller and the second guide roller are parallel to the upper surface of the conveyor belt.

[0020] By ensuring that the label film is parallel to the upper surface of the conveyor belt, the distortion and misalignment of the label film during the attachment process can be reduced. This design helps to improve the attachment accuracy and aesthetics of the label.

[0021] Preferably, the adjustment spring is designed with compression spring material.

[0022] The use of a compression spring provides more stable and reliable tension adjustment. This design helps automatically adjust the tension of the label film during operation, ensuring that the label film always maintains the appropriate tension during the application process. This not only improves the label application effect, but also reduces the risk of damage or peeling of the label film due to uneven tension.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] In the present invention, the driving roller and the driven roller are connected by a conveyor belt transmission, ensuring the stable operation of the conveyor belt, and the driven roller and the second winding roller are synchronously driven. This precise transmission control helps to ensure the accuracy and consistency of the label film during the attachment process. The first winding roller and the second winding roller are connected by the label film transmission, and the tension is controlled by adjusting the spring and the first positioning frame. This design ensures the stability of the tension of the label film during the attachment process and reduces the wrinkling or damage of the label film caused by uneven tension. The first guide roller and the second guide roller are rotatably connected by the second positioning frame, ensuring the precise guidance of the label film during the attachment process. The label film passes under the first guide roller and the second guide roller, ensuring that the label film is parallel to the upper surface of the conveyor belt, thereby improving the attachment accuracy of the label film. The first positioning frame is installed on the top of the second positioning frame by adjusting the spring elasticity. This design enables the device to be flexibly adjusted according to different packaging box sizes and label film thicknesses. The elastic design of the adjusting spring enables the device to adapt to different working conditions, improves the adaptability and reliability of the equipment, and achieves the effect of improving labeling efficiency.
