Description

Technical Field

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

[0002] Canned food is a method of food packaging. The packaging material is tinplate, and the can opening mechanism uses a can opener, or sometimes a can-opening mechanism similar to that of a pull-tab can. The packaging material used is aluminum alloy. Nowadays, most cans are opened using the pull-tab can method for ease of use. Labeling machines are devices that affix stickers or metal foil labels with self-adhesive surfaces to specified packaging containers. Labeling machines are an indispensable part of modern packaging. Currently, the types of labeling machines produced in my country are gradually increasing, and the technical level has also greatly improved. The industry has shifted from the backward situation of manual and semi-automatic labeling to a situation where automated high-speed labeling machines occupy a large market share.

[0003] In related technologies, canned goods are often labeled using conveyor belts. However, during labeling, cans may arrive at the labeling area before the previous can has been labeled, affecting the quality and sequence of labeling and significantly impacting the labeling quality. Furthermore, existing equipment often keeps the cans in one direction during labeling, rotating them only through the contact area between the can and the label to adhere the label to the surface. This labeling method is not stable enough, and cans may not rotate or rotate only slightly, affecting the integrity of the labeling.

[0004] Therefore, we propose a labeling device for canning to solve the above problems. Utility Model Content

A linkage groove is provided on the top of the clamping base 22. A linkage component is provided on the inner side of the linkage groove. All four clamp slots are connected to the same linkage groove.

[0042] In this embodiment, the linkage component includes a pressure metal block 25, a grooved disc 24, and four transmission metal blocks 28. The grooved disc 24 is slidably installed on the inner side of the linkage groove, and an annular groove is opened on the outer side of the grooved disc 24.

[0045] Working principle: When labeling can 19, the worker places can 19 on the clamping base 22. At this time, can 19 comes into contact with the pressure metal block 25. The weight of can 19 itself compresses the pressure metal block 25 downward, which in turn drives the grooved disc 24 downward. The downward movement of the grooved disc 24 causes the annular groove on its surface to move downward, thereby driving the four transmission metal blocks 28 downward. The downward movement of the four transmission metal blocks 28 drives the corresponding clamps 27 downward. However, since all four clamps 27 are rotatably sleeved on the corresponding fixed shafts 26, the four clamps 27... The can only rotate around the corresponding fixed axis 26 as the center. The four clamps 27 rotate to hold the cans 19. After placing multiple cans 19, the conveyor 1 is started. The conveyor 1 drives multiple rotating bases 20 to move, thereby moving multiple cans 19. After the first can 19 passes the stop plate 15, the ratchet plate 14 at the bottom of the stop plate 15 stops rotating due to the influence of the wedge block 16. At this time, the stop bar of the stop plate 15 blocks the subsequent cans 19 to prevent them from moving. The first can 19 moves to the designated position and the label sticker is applied to the outside of the labeling roller 9. 7. Upon contact, the servo motor 21 starts, driving the clamping base 22 to rotate, which in turn drives the can 19 to rotate. During this rotation, the can 19 moves, allowing the label sticker 7 to adhere better to its surface. After adhesion, the can 19 moves away from the label sticker 7. The winding servo motor 4 starts, driving the winding roller 5 to wind up the can, moving the new label sticker 7 to the designated position for subsequent labeling. Simultaneously, the can 19 moves to the designated position and contacts the linkage rod 12, compressing it. The linkage rod 12 rotates around the linkage shaft 11, causing... The traction rope 13 moves, which in turn pulls the linkage slider 17 to move, thereby causing the wedge block 16 to move and release the ratchet disc 14 from its limit. The subsequent cans 19 push the stop disc 15 and the ratchet disc 14 to rotate. However, at this time, the first can 19 has moved away from the linkage rod 12 and no longer causes pressure on it. The return spring 18 drives the linkage slider 17 to reset. The linkage slider 17 drives the wedge block 16 to limit the ratchet disc 14 again. The stop disc 15 blocks the subsequent cans 19, so that only one can 19 passes through the stop disc 15 to enter the labeling area at a time.

[0046] The technological advancement of this invention compared to the prior art is that the labeling sequence of cans 19 can be controlled, thereby effectively preventing multiple cans 19 from entering the labeling area at the same time, increasing the practicality of the equipment. When the can 19 comes into contact with the label sticker 7, the rotation of the can 19 can be controlled, thereby improving the stability during labeling and ensuring that the label can be stably attached to the outside of the can 19.
