Description

Technical Field

[0001] The utility model relates to the technical field of labeling devices, in particular to a labeling device for a pre-prepared food packaging box. Background Art

[0002] Pre-prepared food refers to food that has been processed and cooked in advance for easy storage, transportation and use. Pre-prepared food is usually processed in a factory or kitchen, and then packaged for consumers to buy and eat. The packaging box, as the name suggests, is a box used to package products. It can be classified by material, such as paper boxes, iron boxes, wooden boxes, etc. The labeling device is one of the indispensable components of product production and packaging. It is mainly a device that uses adhesives to stick labels such as identification codes or anti-counterfeiting marks to designated locations on products.

[0003] And in the document with publication number CN220333245U, a labeling device for pre-prepared food packaging boxes is mentioned. The device has the following steps: when in use, the packaging box is placed on the conveyor belt, and when the first rotating roller is driven to rotate by the motor, the second rotating roller and the third rotating roller are driven to rotate at the same time, so that the conveyor belt remains in a rotating state; when the conveyor belt moves, the packaging box slides on the fixed plate, so that one side of the packaging box conflicts with the limit frame to fix the packaging box; when the packaging box moves to the lower end of the marking machine, the hydraulic cylinder drives the marking machine connected to the connecting plate to move downward to label the packaging box; when the labeling is completed, the packaging box moves to the lower end of the label pressing cylinder, and the hydraulic cylinder drives the label pressing cylinder connected to the connecting plate to move downward to press the surface of the packaging box. The above is the entire working principle of the utility model, but there are still certain defects that need to be optimized. The specific defects are as follows: the limit frame cannot be adjusted, and the packaging box may be inaccurately positioned due to vibration or speed changes during transportation, affecting the labeling effect.

[0004] Therefore, it is particularly important to design a labeling device for a pre-prepared meal packaging box to change the above technical defects and improve the overall practicality. Utility Model Content

During the conveying process, the electric push rod 303 works to drive the fiberboard 305 close to the packaging box. At this time, the silicone ball 309 contacts the packaging box and flexibly fixes the packaging box through the elastic action of the pressure spring 307 to prevent it from moving or sliding. When it reaches the designated position, the marking component 401 starts to work, and the hydraulic rod drives the marking machine on the connecting plate to descend to perform precise marking operations on the packaging box. After the marking is completed, the labeling component 402 starts to work. It is also driven by the hydraulic telescopic rod. The labeling machine descends above the packaging box and accurately sticks the label on the designated position. Then the electric push rod 303 is withdrawn. The packaging box that has completed the labeling operation continues to move forward along the conveyor belt. With the rotation of the conveyor belt 2, the packaging box is separated from the fiberboard 305 and finally reaches the collection box at one end of the conveyor table 1;

[0025] The guide plate 301 is obliquely arranged on the fixed plate 3, and a slot is provided on the guide plate 301, so that the limit plate 305 and the fixed block 304 can pass through. The electric push rod 303 is arranged on the mounting plate 302, and the output end of the electric push rod 303 is fixedly connected to the fixed block 304, so as to adjust the position of the silicone ball 309. The interior of the limit cylinder 306 is provided with a receiving cavity for accommodating the compression spring 307 and the mounting block 308. The mounting block 308 and the limit cylinder 306 are fixedly connected, so as to facilitate the silicone ball 309 to move.

A collection box is provided at one end of the conveying platform 1 for collecting finished products after labeling. A pressure sensor is provided on the silicone ball 309 for easy support of the electric push rod 303.

[0026] The working process of the utility model is as follows: when using the labeling device for pre-prepared food packaging boxes, the pre-prepared food packaging boxes are first placed on the fixed plate 3. With the movement of the conveyor belt 2, the packaging boxes gradually move forward. During the conveying process, the electric push rod 303 works to drive the limit plate 305 close to the packaging box. At this time, the silicone ball 309 contacts the packaging box, and the packaging box is flexibly fixed through the elastic action of the pressure spring 307 to prevent it from moving or sliding. When it reaches the designated position, the marking component 401 starts to work, and the hydraulic rod drives the marking machine on the connecting plate to descend, and performs precise marking operation on the packaging box. After the marking is completed, the labeling component 402 starts to work, which is also driven by the hydraulic telescopic rod. The labeling machine descends to the top of the packaging box and accurately sticks the label at the designated position, and then the electric push rod 303 is withdrawn. The packaging box that completes the labeling operation continues to move forward along the conveyor belt. With the rotation of the conveyor belt 2, the packaging box is separated from the fiberboard 305 and finally reaches the collection box at one end of the conveyor table 1.
