[0001] This utility model relates to the field of labeling machine technology, and specifically to a labeling mechanism for a labeling machine. Background Technology

[0002] A labeling machine is a device that affixes rolls of self-adhesive labels to PCBs, products, or prescribed packaging. The labeling mechanism is the core component of the labeling machine, and its main function is to accurately affix labels to products or packaging. Labeling machinery is a mechanical device that uses a certain electromechanical control mechanism to affix and stick labels to predetermined positions by humans, thereby achieving the purpose of packaging. It can greatly reduce labor costs and improve efficiency.

[0003] Traditional labeling mechanisms are not capable of adapting to different sticker sizes and can only effectively pick up stickers of the same size. If the size of the sticker changes during product changeover, the sticker will fall off more frequently during turnover, requiring the entire labeling mechanism to be replaced, resulting in low maintenance efficiency.

[0022] The present invention will be further described in detail below with reference to embodiments:

[0023] like Figures 1-5 As shown, this utility model provides a labeling mechanism for a labeling machine, including a conveyor frame 1 and a sticker feeding mechanism 11. The sticker feeding mechanism 11 is disposed on the top of the conveyor frame 1, an adjustable labeling component 2 is disposed on the top of the conveyor frame 1, and a pressing component 3 is disposed on the top of the conveyor frame 1.

[0024] The adjustable labeling assembly 2 includes a support arm 28, a crossbar 281 fixedly mounted at the bottom of the support arm 28, a folding bar 282 slidably connected to the outer wall of the crossbar 281, a sleeve frame 283 fixedly mounted to the outer wall of the folding bar 282, a strip support rod 284 slidably connected to the inner wall of the folding bar 282 and the sleeve frame 283, and a vacuum suction cup 285 fixedly mounted to the inner wall of the strip support rod 284. The conveyor frame 1 is used to transport the goods to be labeled. The sticker feeding mechanism 11 is a commercially available device that can be purchased by those skilled in the art. No structural modifications have been made to the device in this document, and those skilled in the art are familiar with its working principle based on their professional knowledge and can apply it proficiently. The sticker feeding mechanism 11 is used to transport rolls of self-adhesive labels to the position where the adjustable labeling assembly 2 is used. Generally, the shape of the stickers is... The sticker is square. When the side length of the sticker changes, the strip support rod 284 can be slid in the inner cavity of the sleeve frame 283 to adjust the four vacuum suction cups 285 to the center point to adapt to the size of the sticker. If the sticker expands into a rectangle, the folding rod 282 can be slid on the outer wall of the horizontal bar 281 to adjust the distance between the two vacuum suction cups 285, so that the sticker can be effectively adsorbed onto the mechanism without replacing the entire labeling mechanism, resulting in high maintenance efficiency. The top of the folding rod 282 is threaded with a bolt, which is used to position the folding rod 282 on the horizontal bar 281. The top of the sleeve frame 283 is threaded with a bolt, which is used to position the strip support rod 284 inside the sleeve frame 283. The top of both the horizontal bar 281 and the strip support rod 284 are coated with scale lines to facilitate position adjustment.

[0025] Furthermore, such as Figure 2 As shown, the adjustable labeling assembly 2 also includes a support stand 21, which is fixedly installed on the top of the conveyor frame 1. The number of support stands 21 is set to two, and a crossbeam 22 is fixedly installed between the adjacent sides of the two support stands 21. The support stands 21 are used to provide support for the entire adjustable labeling assembly 2. The design of the crossbeam 22 can strengthen the connection between the two support stands 21.

[0026] Furthermore, such as Figure 2 As shown, a track rod 23 is fixedly installed between two adjacent sides of the two support bases 21, and a lead screw 24 is rotatably connected between the two adjacent sides of the two support bases 21. A servo motor 25 is fixedly installed on the side of one of the support bases 21. The output shaft of the servo motor 25 is fixedly connected to the end of the lead screw 24. A sliding seat 26 is threadedly connected to the outer wall of the lead screw 24. The sliding seat 26 is slidably connected to the outer wall of the track rod 23. By controlling the servo motor 25 to work, the lead screw 24 can be rotated, which in turn can drive the sliding seat 26 to slide on the outer wall of the track rod 23, providing power for the overall left and right movement of the support arm 28.

[0027] Furthermore, such as Figure 3 As shown, an extension seat 27 is fixedly installed on the outer wall of the sliding seat 26. A first electric cylinder 271 is fixedly installed on the top of the extension seat 27. The telescopic end of the first electric cylinder 271 extends to the bottom of the extension seat 27 and is fixedly connected to a supporting frame 272. The support arm 28 is fixedly installed at the bottom of the supporting frame 272. By controlling the first electric cylinder 271 to telescopically operate, the supporting frame 272 can be raised and lowered, providing power for the overall up and down movement of the support arm 28.

[0028] Furthermore, such as Figure 3 As shown, a vacuum pump 273 is fixedly installed at the bottom of the inner cavity of the receiving frame 272. A strip tube 274 is fixedly connected to the suction end of the vacuum pump 273. The strip tube 274 is fixedly installed at the bottom of the inner wall of the receiving frame 272. A solenoid valve 276 is fixedly connected to the outer wall of the strip tube 274. A branch tube 275 is threadedly connected to the side of the strip tube 274. The end of the branch tube 275 away from the strip tube 274 is threadedly connected to the vacuum suction cup 285. The working end of the vacuum pump 273 is connected to the four vacuum suction cups 285 through the strip tube 274 and the branch tube 275. Controlling the operation of the vacuum pump 273 can generate negative pressure at the vacuum suction cups 285 to adsorb the sticker. After the sticker moves to the designated position, the vacuum pump 273 is turned off and the solenoid valve 276 is opened, so that the inner cavity of the strip tube 274 is connected to the outside, the negative pressure at the vacuum suction cups 285 is released, and the sticker is released.

[0029] Furthermore, such as Figure 5 As shown, the pressing assembly 3 includes a support frame 31, which is fixedly installed on the top of the conveyor frame 1. A second electric cylinder 32 is fixedly installed on the top of the support frame 31. A lifting seat 33 is fixedly installed on the telescopic end of the second electric cylinder 32. Controlling the telescopic operation of the second electric cylinder 32 can drive the lifting seat 33 to move up and down, providing power for the overall up and down movement of the pressing roller 37.

[0030] Furthermore, such as Figure 5 As shown, a limiting rod 34 is fixedly installed at the bottom of the lifting seat 33. An L-shaped connecting seat 35 is slidably connected to the outer wall of the limiting rod 34. An elastic element 36 is fixedly installed at the top of the L-shaped connecting seat 35. The top of the elastic element 36 is fixedly connected to the bottom of the lifting seat 33. A pressure roller 37 is rotatably connected to the outer wall of the L-shaped connecting seat 35. The limiting rod 34 is used to limit the up and down movement of the L-shaped connecting seat 35. Through the elastic force of the elastic element 36, the pressure roller 37 can be pressed against the top of the goods, so that the sticker can fully adhere to the top of the goods and improve the stability of the label.

[0031] The working principle of the labeling mechanism of this labeling machine will be explained in detail below.

[0032] like Figures 1-5As shown, during use, the goods are transported by the conveyor frame 1 and the stickers are transported by the sticker feeding mechanism 11. After the goods reach the labeling position, the controller controls the first electric cylinder 271 to extend, driving the support arm 28 to move down as a whole. Then, the controller controls the vacuum pump 273 to work, so that negative pressure is generated at the vacuum suction cup 285 to adsorb the sticker. Then, the controller controls the first electric cylinder 271 to reset, and then controls the servo motor 25 to work, driving the support arm 28 to move to the right as a whole. Then, the controller controls the first electric cylinder 271 to extend, causing the sticker to move down and adhere to the top of the goods. The vacuum pump 273 is turned off and the solenoid valve 276 is opened, so that the vacuum suction cup 285 is released from the negative pressure state, completing the release of the sticker, that is, realizing the labeling function. After the goods move to the bottom of the pressure roller 37, the controller controls the second electric cylinder 32 to extend, so that the pressure roller 37 is pressed against the top of the goods by the elastic force of the elastic element 36, so that the sticker can fully adhere to the top of the goods.

[0033] Generally, stickers are square in shape. When the side length of the sticker changes, by loosening the bolts at the top of the frame 283, the strip support rod 284 can be slid in the inner cavity of the frame 283 to adjust the four vacuum suction cups 285 to the center position to adapt to the size of the sticker. If the sticker is expanded into a rectangle, by loosening the bolts at the top of the folding rod 282, the folding rod 282 can be slid on the outer wall of the crossbar 281 for adjustment, so that the distance between the two vacuum suction cups 285 on the left and right changes, so that the sticker can be effectively adsorbed on this mechanism, improving the maintenance efficiency during production changeover.

[0034] It is worth noting that this solution aims to protect the physical structure, but does not protect the circuit and software control. The proposed processing circuit is merely a supplementary explanation of the feasibility and authenticity of this utility model. This utility model does not require protection of the algorithm and circuit technology. It is worth emphasizing that although this solution does not describe the electronic control program in detail, those skilled in the art can be familiar with and apply it based on their professional knowledge.

[0035] It should be noted that, in the description of this disclosure, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joint" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0036] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
