[0002] Cups require labeling during production. Referring to Chinese patent publication number CN208615291U, "An In-Mold Labeling Device for Cups," this patent indicates that cups typically require labeling on their outer walls after molding, usually through screen printing or heat transfer paper. However, this labeling process is complex, has low efficiency, and the applied labels are prone to fading and peeling, affecting product quality. Furthermore, this equipment still suffers from poor labeling quality and convenience. Therefore, we propose an automatic labeling device for cup label detection to address these issues. Summary of the Invention

[0009] Preferably, the support frame is hollow and has multiple positioning holes symmetrically opened on the top, and a negative pressure device is connected to the outside of the support frame.

[0010] Preferably, a second drive motor is fixedly installed inside the labeling machine body, a drive gear is fixedly sleeved at the output end of the second drive motor, and a transmission gear is fixedly sleeved on the outer side of the labeling cup holder.

[0016] Preferably, the top of the negative pressure cleaning rack has multiple cleaning slots symmetrically arranged.

[0017] This invention provides an automatic labeling device for detecting cup labels. Compared with the prior art, it has the following advantages:

[0018] (1) The automatic labeling device for cup label detection, through the cooperation of the labeling cup holder and the transfer frame, can absorb the printed label by moving the transfer frame during the labeling process, and then apply the label to the surface of the cup to be labeled after adjusting the angle. During the labeling process, the labeling cup holder drives the cup to be labeled and the transfer frame to rotate synchronously, which can further ensure the labeling effect. At the same time, it can be used for labeling cups of different sizes and heights, improving the labeling accuracy and convenience.

[0019] (2) The automatic labeling device for cup label detection, through the setting of the labeling cup rack, when the cup to be labeled is placed inside the labeling cup rack, the support frame is pressed and can move down, squeezing the support spring. As the cup to be labeled contacts the side limit frame and moves down along multiple spherical bodies until the cup to be labeled is located in the center position inside the labeling cup rack, the negative pressure device can then be used to position the cup to be labeled through multiple positioning holes, and can automatically calibrate the cup to be labeled, improving the ease of operation of the device, while ensuring the subsequent labeling effect and labeling accuracy.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-8 The present invention provides two technical solutions, specifically including the following embodiments:

[0031] Example 1:

[0032] In this embodiment of the invention, an automatic labeling device for cup label detection includes a labeling machine body 1. A label peeling printer 4 is fixedly installed inside the labeling machine body 1. A winding roller 5, a limiting roller 6, a printing peeling mechanism 7, and a rewind roller 8 are respectively installed on the top of the label peeling printer 4 for printing and peeling labels.

[0033] Specifically, the label peeling printer 4 is used to print labels and automatically separate the labels from the label paper during the conveying process. The specific implementation is as follows: first, the label roll is wrapped around the winding roller 5, then the end of the label roll is wrapped around the limiting roller 6 and the printing peeling mechanism 7 respectively, and then wound onto the rewind roller 8. The rewind roller 8 is used to recycle the label paper. During the labeling operation, the winding roller 5 performs the unwinding operation, and the rewind roller 8 performs the winding operation. The label can enter the printing peeling mechanism 7 to complete the separation of the label paper and complete the printing process at the same time. The label peeling printer 4 is an existing device.

[0034] The labeling machine body 1 has an outer cover printing cover 2 fixedly installed at the end. The labeling cup holder 9 is installed inside the outer cover printing cover 2, and the labeling cup holder 9 holds a cup 10 to be labeled. The outer cover printing cover 2 has a transfer frame 12 installed inside, which is used to attach the peeled label to the outer surface of the cup 10 to be labeled.

[0035] When labeling a cup 10, it should first be placed inside the labeling cup holder 9. At this time, the printed label can be transferred by moving the transfer frame 12 and then affixed to the outer surface of the cup 10.

[0036] A limiting slide 13 is slidably installed inside the printing cover 2 of the outer cover. An electric telescopic rod 1301 is fixedly installed inside the labeling machine body 1 to drive the limiting slide 13 to move horizontally. A transmission roller 1202 is fixedly installed at the end of the transfer frame 12. The transmission roller 1202 is rotatably installed at the end of the limiting slide 13. A negative pressure device 15 is fixedly installed above the end of the limiting slide 13. The transmission roller 1202, the negative pressure device 15 and the transfer frame 12 are interconnected. Multiple adsorption holes 1201 are symmetrically opened inside the transfer frame 12 to adsorb the printed labels.

[0037] When the label is printed and separated from the label paper, it can be located at the end of the printing peeling mechanism 7. At this time, the electric telescopic rod 1301 drives the limiting slide 13 and the transfer frame 12 to move horizontally, so that the side of the transfer frame 12 with the suction hole 1201 contacts the label. Then, the negative pressure device 15 runs, and the label can be adsorbed through the suction hole 1201 until the label is affixed to the surface of the cup 10 to be labeled.

[0038] When the transfer rack 12 absorbs the label, it contacts the smooth side of the label, which facilitates the subsequent labeling operation.

[0039] A drive motor 14 is fixedly installed at the bottom of the limiting slide 13. A transmission belt 1203 is connected between the output end of the drive motor 14 and the end of the transmission roller 1202 to drive the transmission roller 1202 and the transfer frame 12 to rotate and attach the label to the outer surface of the cup 10 to be labeled.

[0042] The support frame 903 is hollow and has multiple positioning holes 9031 symmetrically opened on the top. A negative pressure device is connected to the outside of the support frame 903.

[0043] When the cup 10 to be labeled is placed inside the labeling cup holder 9, the support frame 903 is pressed down and squeezes the support spring 9032. As the cup 10 to be labeled comes into contact with the side limit frame 904, it can move down along multiple spherical bodies 9041 until the cup 10 to be labeled is located in the center position inside the labeling cup holder 9. Then, through the operation of the negative pressure device, the cup 10 to be labeled can be positioned through multiple positioning holes 9031. It can automatically calibrate the position for cups 10 to be labeled of different sizes, improve the ease of operation of the equipment, and at the same time ensure the subsequent labeling effect and labeling accuracy.

[0044] An electric cylinder is installed on the inner bottom of the labeling cup holder 9 to drive the support frame 903 and the cup 10 to be labeled to move upward, thereby adjusting the labeling height of the cup 10 to be labeled.
