The first detection mechanism detects whether there are bottles on the conveyor line, and the second detection mechanism detects whether there are labels on the bottles. When a bottle is found to be without a label, air can be blown onto the bottle on the conveyor line through the air outlet of the air pipe, causing the unlabeled bottle to be blown off, preventing empty bottles from being discarded or entering the market, and reducing customer complaints.

[0004] However, the existing label re-inspection device does not have an effective product supplementary lighting structure inside the device, which makes the label detection parts susceptible to the influence of ambient light during the use of the device, resulting in missed detections. This affects the re-inspection effect of the device and reduces the stability of the device.

[0005] Therefore, in order to address the above problems, there is an urgent need for innovative design based on the existing missing label re-inspection device. Utility Model Content

[0008] Also includes:

[0009] The product conveyor belt is installed inside the machine body shell, and a first positioning block is provided on the outside of the machine body shell. An installation plate is connected to the outside of the first positioning block, and a first limiting rod passes through the middle of the installation plate. A light-shielding curtain is provided on the lower side of the installation plate, and a supplementary light plate is provided on the right side of the label detection head.

[0010] A first drive motor is mounted on the upper side of the machine body shell, and a drive rod is connected to the lower end of the first drive motor. A labeling head is connected to the lower side of the drive rod, and a guide rod is connected to the outer side of the labeling head.

[0011] In one possible implementation, the mounting plate is engaged with the first positioning block, and the first limiting rod is threadedly connected to both the first positioning block and the mounting plate.

[0012] In one possible implementation, the light-blocking curtains are evenly distributed on the underside of the mounting plate, and the mounting plate is symmetrically arranged about the central axis of the outer casing.

[0013] In one possible implementation, the drive rod is threadedly connected to the labeling head, and the labeling head is slidably connected to the guide rod.

[0014] In one possible implementation, the connecting assembly includes a connecting block mounted on the outside of the label cylinder, and a second positioning block is provided inside the connecting block, with a second limiting rod extending through the left side of the second positioning block;

A guide block is provided in the middle of the support plate, and a spring damper is connected to the upper side of the support plate.

[0018] The support plate and the guide block are slidably connected, and the support plate is symmetrically arranged about the central axis of the blocking plate.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This labeling machine's missing label re-inspection device has an effective product supplementary lighting structure inside the device, making the label detection parts less susceptible to the influence of ambient light during use, thus preventing the re-inspection effect from being affected and improving the stability of the device. At the same time, it facilitates the limiting and blocking of products with missing labels during use, allowing the device to stably perform re-labeling operations on these products, improving the efficiency of the device and resulting in a better performance. Specifically, as shown below:

[0020] 1. The mounting plate and the light-shielding curtain are installed on the left and right sides of the machine body shell by the first positioning block and the first limiting rod. At the same time, the supplementary light plate and the power supply battery provide supplementary lighting to the internal space of the machine body shell. This allows the label detection head to effectively reduce the influence of ambient light on the products entering the device during the detection process, avoid the device from missing detection due to the influence of natural light, and improve the stability of the device.

[0021] 2. The first drive motor, in conjunction with the drive rod, pushes the labeling head to move downward along the guide rod, so that the labeling head pushes the blocking plate to block the product being conveyed to the right, making it easier for the device to relabel the product, preventing the product from shifting during the relabeling process, and improving the relabeling efficiency of the device.

[0022] 3. By rotating the second limiting rod, the second limiting rod rotating outward is released from the series limit on the label tube, which makes it easier for the operator to replace and replenish the label tube when the label material is insufficient, reducing the downtime of the device and improving the efficiency of the device.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-6 This utility model provides a technical solution: a labeling machine missing label re-inspection device, including a machine body shell 1, a product conveyor belt 2, a power supply battery 3, a label detection head 4, a supplementary light plate 5, a first positioning block 6, a mounting plate 7, a first limiting rod 8, a light-blocking curtain 9, a first drive motor 10, a drive rod 11, a labeling head 12, a guide rod 13, a label cylinder 14, a connecting block 15, a second positioning block 16, a second limiting rod 17, a waste film take-up cylinder 18, a second drive motor 19, a blocking plate 20, a support plate 21, a guide block 22, and a spring damper 23.

[0032] Specifically, such as Figure 1 , Figure 2 and Figure 3As shown, before the device is used, the mounting plate 7 is installed on the left and right sides of the machine body shell 1 along the first positioning block 6. At this time, due to the engaging connection structure between the first positioning block 6 and the mounting plate 7, the first positioning block 6 can initially limit the mounting plate 7 to the outside of the machine body shell 1. Then, the first limiting rod 8 passing through the middle of the mounting plate 7 is rotated. Due to the threaded connection structure between the first limiting rod 8 and the mounting plate 7 and the first positioning block 6, the first limiting rod 8 rotating inward connects the mounting plate 7 and the first positioning block 6 together. At this time, the light-blocking curtain 9 connected to the lower end of the mounting plate 7 provides simple light-blocking treatment for the inlet and outlet ports on the left and right sides of the machine body shell 1. At this time, the inside of the machine body shell 1... The product conveyor belt 2 transports the products processed by the labeling machine to the interior of the machine body 1. At the same time, the supplementary light plate 5 installed on the upper left side of the machine body 1 is driven by the power supply battery 3 to generate supplementary light, so that the light can supplement the surface of the product. At this time, the label detection head 4 installed on the left side of the supplementary light plate 5 performs label detection on the products entering the device, so that the products placed on the upper side of the product conveyor belt 2 are subject to secondary detection by the device. Meanwhile, its light-blocking and supplementary light structure can effectively reduce the influence of natural light on the detection results of the label detection head 4, improve the detection and processing quality of the device, avoid the situation of detection omissions caused by the influence of natural light, and improve the stability of the device.

[0033] Specifically, such as Figure 4 , Figure 5 and Figure 6As shown, when the label detection head 4 detects a missing label on the product, the first drive motor 10 located on the upper side of the machine housing 1 is activated. This causes the first drive motor 10 to drive the drive rod 11 connected to its lower side to rotate on the upper side of the machine housing 1. Because of the threaded connection between the drive rod 11 and the labeling head 12, the drive rod 11 can effectively push the labeling head 12 downwards during rotation. However, due to the sliding connection between the labeling head 12 and the guide rod 13, the labeling head 12 is guided and limited by the guide rod 13 during downward displacement, preventing the labeling head 12 from generating excessive pressure during downward displacement. When the labeling head 12 shifts position, it pushes the lower connected baffle plate 20 to contact the product conveyor belt 2, causing the baffle plate 20 to intercept and block the product transported to the right. The labeling head 12 continues to shift downwards, causing the baffle plate 20 to push the outer connected support plate 21 upwards, compressing the spring damper 23. Due to the sliding connection between the support plate 21 and the guide block 22, the upward-shifting support plate 21 is guided by the guide block 22. Simultaneously, the downward-shifting labeling head 12 pushes the label it is applying to adhere to the product surface. At the same time, the second drive motor 19 drives the waste film take-up drum 18 connected to its front end at the labeling head... The internal rotation of 12 causes the waste film winding drum 18 to wind the used label film to the right, thus completing the labeling process. An effective blocking structure prevents the product from shifting during the labeling process, improving the labeling efficiency of the device. Simultaneously, after the device is used, rotating the second limiting rod 17 that passes through the outer side of the label drum 14 releases the series restriction on the label drum 14 and the second positioning block 16 due to the threaded connection between the second limiting rod 17, the label drum 14, and the second positioning block 16. This allows the operator to pull the label drum 14 to the left to remove it. The new label cylinder 14 is re-verified by installing the second positioning block 16 inside the connecting block 15. Due to the engaging connection between the second positioning block 16 and the label cylinder 14, the second positioning block 16 can initially position the label cylinder 14 inside the connecting block 15. At the same time, the second limiting rod 17 connected to the outside of the label cylinder 14 is rotated in the opposite direction, so that the second limiting rod 17 reconnects the label cylinder 14 and the second positioning block 16 in series. This completes the quick replacement of the label cylinder 14, which is convenient for operators to replace and replenish the label cylinder 14 when the label material is insufficient, reducing the downtime of the device and improving the efficiency of the device.
