Description

Technical Field

[0001] This utility model relates to the field of labeling machine technology, and in particular to a labeling device for canned fruits and vegetables. Background Technology

[0002] Fruit and vegetable can labeling equipment is a key piece of equipment in food packaging production lines. It is used to automatically, efficiently, and accurately affix labels to the surface of cans, ensuring that product information is clear and readable and complies with food safety and packaging regulations.

[0003] Chinese Patent No. CN210681442U discloses an automatic labeling device for canned goods, including a workbench. A dust removal component is installed at one end of the upper part of the workbench. A first fixed seat is welded to one side of the middle of the workbench. A first pneumatic rod is fixedly installed in the middle of the inner side of the first fixed seat by fixing screws. A clamping seat is fixedly installed at one end of the first pneumatic rod by fixing screws. Buffer springs are installed at equal intervals on the inner side of the clamping seat. This utility model has a scientific and reasonable structure, is safe and convenient to use, and is equipped with a dust removal component. By sleeved on the outside of the suspension rod, the dust removal roller can remove dust from the surface of the can when the can moves above the conveyor belt, making the label adhere more stably to the can and preventing it from falling off. Furthermore, the first and second Velcro fasteners facilitate the disassembly and cleaning of the dust removal cloth, improving the dust removal effect of the cloth.

[0004] However, the aforementioned publicly available solutions have the following shortcomings: the existing fruit and vegetable can labeling devices cannot automatically smooth and tighten the labels after they are applied to the cans, which makes the labels prone to peeling off. At the same time, they cannot guarantee that the cans will remain in a fixed position when the labels are applied, which affects the labeling effect. Utility Model Content

[0009] The slide rail is mounted on the labeling mechanism. A sliding frame is mounted on the inner side of the slide rail. A squeezing roller is rotatably mounted on the sliding frame. There are two sliding frames symmetrically arranged about the slide rail. The labeling mechanism drives the sliding frame to move downward. When the sliding frame drives the squeezing roller to move near the label on the can, the squeezing roller moves along the can to both sides to squeeze and smooth the label.

[0010] Preferably, it also includes a positioning component, which includes a clamping platform, a fixing plate, and a telescopic rod.

[0011] The clamping platform is located on the top of the conveyor belt, the fixed plate is located on the top of the clamping platform, the telescopic rod is located on the side of the fixed plate, the outer side of the telescopic rod is provided with a spring, and the end of the telescopic rod away from the fixed plate is provided with a clamping plate.

[0019] The rotating rod is located at the end of the connecting shaft away from the second synchronous wheel. The support plate is located on the outside of the connecting shaft. The bottom of the support plate is connected to the top of the conveyor table. The push rod is rotatably located at the end of the rotating rod away from the connecting shaft. The push rod and the rotating rod are connected by a plug rod. The side of the conveyor belt is equipped with a locking block.

[0020] Preferably, the labeling mechanism includes a support frame, a cylinder, a push rod, a labeling machine, and a smoothing component;

[0021] The support frame is located on top of the transport platform, the cylinder is located on top of the support frame, the push rod is located at the output end of the cylinder, and the labeling machine is located at the bottom of the push rod.

[0022] The smoothing component is mounted on the push rod and is used to press the label affixed to the can firmly.

[0025] Compared with the prior art, the present invention has the following beneficial technical effects:

[0026] 1. Through the labeling mechanism, the cylinder drives the labeling machine to move and affix the label to the fruit and vegetable cans. At the same time, the connecting plate drives the extrusion roller to move downward, so that the extrusion roller moves along the outer surface of the can to smooth the label. This can effectively remove the air between the label and the can surface, avoid the formation of air bubbles, eliminate wrinkles, make the label flat and adhere, and reduce the risk of label falling off or curling due to friction or changes in environmental humidity. This extends the integrity of the label on the shelf life, eliminates the need for secondary manual adjustment, reduces production steps, and improves the degree of automation.

[0027] 2. Through the setting of positioning components and intermittent conveying mechanism, the motor drives the push rod to intermittently push the clamping block, thereby causing the conveyor belt to move intermittently. This is used to cooperate with the progress and return work of the cylinder. This ensures that each can is positioned and stops when it reaches the labeling station, avoiding label offset or poor adhesion caused by continuous movement of the can. The shape of the clamping plate fits the can perfectly, so that the can is just right and will not move during labeling and smoothing, affecting the labeling effect. Attached Figure Description

[0041] Example 2

[0042] like Figure 4As shown, this utility model proposes a labeling device for canned fruits and vegetables. Compared with Embodiment 1, this embodiment details the structure of the labeling machine 604.

[0043] The labeling machine 604 includes a support frame 601, a cylinder 602, a push rod 603, a labeling machine 604, and a smoothing component. The support frame 601 is located on the top of the transport table 1, the cylinder 602 is located on the top of the support frame 601, the push rod 603 is located at the output end of the cylinder 602, and the labeling machine 604 is located at the bottom of the push rod 603.

[0044] In summary, when using this utility model, the can is aligned with the placement opening on the clamping table 501, and then the can is pressed down. The can is pressed against the clamping plate 505 on both sides, thus being installed on the placement opening. The spring 504 rebounds to fix the can. Then, the motor 401 and cylinder 602 are started. The motor 401 drives the rotating shaft 402 to rotate, which in turn drives the synchronous pulley 403 to rotate. The synchronous pulley 403 drives the synchronous pulley 404 to rotate via the synchronous belt 405. The synchronous pulley 404 drives the rotating rod 407 to rotate via the connecting shaft 406. The rotating rod 407 drives the pushing rod 408 to move. When the pushing rod 408 moves forward, it cooperates with the locking block 409, thereby driving the locking block 409 to move. The locking block 409 drives the can forward via the conveyor belt 2. During the return stroke, the pusher disengages from the locking block 409, preventing the locking block 409 from moving. The pusher head and the slot on the locking block 409 can engage, ensuring stable movement of the locking block 409 when the pusher rod 408 rotates. Simultaneously, the cylinder 602 moves the push rod 603, which in turn moves the labeling machine 604. When the labeling machine 604 moves onto the can, it affixes the label. The cylinder 602, through the connecting plate 605 and the slide rail 607, moves the squeezing roller 609 downward. After contacting the can, the squeezing roller 609 moves to both sides under the action of the can. The squeezing roller 609 moves along the outer surface of the can, smoothing the label and making it adhere tightly to the can. Then, the cylinder 602 returns, and the squeezing roller 609 returns to its original position under the action of the spring 611.
