Description

Technical Field

[0002] CN 219565793 U discloses a "label inspection machine comprising a machine platform, wherein a mounting plate is fixedly provided on the top of the machine platform and rotatably connected to one side of a plurality of conveying rollers... The dust suction fan is electrically connected to an external power supply via an external dust suction fan switch." When the conveying rollers are conveying labels, the dust suction fan is activated to create a negative pressure in the dust suction pipe. The airflow separates dust attached to the label surface and carries the dust through the dust suction plate into the dust suction pipe. After passing through the dust suction fan, the dust is accumulated in the dust collection box through the connecting pipe, thereby preventing the effect of label printing quality inspection from being affected.

[0003] Regarding the above-mentioned related technologies, the inventor believes that during the actual use of the label inspection machine, due to the influence of factors such as the suction force of the vacuum tube and the airflow, when the airflow contacts the label, it will cause significant interference and friction on the label, thereby causing the label to shake and affect the inspection results.

[0004] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application. Therefore, it may contain information that does not constitute the prior art known to ordinary technicians in this field. Utility Model Content

[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The embodiment of the present application discloses a label printing quality inspection machine. Figure 1-3A label printing quality inspection machine includes a frame 1, a label feeding tray 2 and a label winding tray 3 are respectively installed at the front ends of the frame 1, a plurality of conveying shafts 4 are installed on the inner sides of the label feeding tray 2 and the label winding tray 3 on the frame 1, a dust collection component 5 is installed on the top of the frame 1, and the dust collection component 5 includes a dust collector 501 installed on the frame 1, a dust collection pipe 503 is installed on the dust collector 501, and a dust collection plate 502 is connected to the end of the dust collection pipe 503. There is a label detection camera 6. Several groups of label stabilization components 7 are installed on the upper side of the conveyor shaft 4 on the frame 1. The label stabilization component 7 includes a movable roller 701 installed on the frame 1. A fixed roller 702 is installed on the upper side of the movable roller 701 on the frame 1. A dust collection plate 502 is located on the upper side of the label stabilization component 7. An adjustment component 8 is installed on the rear side of several movable rollers 701. The dust collection plate 502 and the label detection camera 6 are respectively located on the upper side of two adjacent groups of fixed rollers 702;

[0020] By adopting the above technical solution, the label is clamped by the dynamic roller 701 and the fixed roller 702, which increases the friction between the label and the base paper, thereby preventing the label from sliding or shaking during transportation, reducing the impact of airflow on the label, and reducing the possibility of label shaking.

[0021] Reference Figure 2 The fixed roller 702 is mounted on the frame 1 through a bearing. A guide groove is provided on the lower side of the fixed roller 702 on the frame 1. The movable roller 701 is slidably mounted in the corresponding guide groove. The outer side of the movable roller 701 is wrapped with a flexible sponge.

[0022] By adopting the above technical solution, the movable roller 701 is fine-tuned and moved upward to adjust the tension during the label conveying process, further preventing the label from shaking. The flexible sponge can provide a buffering effect when the label passes through the movable roller 701 and the fixed roller 702. When the label is affected by the airflow, the sponge can reduce the direct force of the airflow on the label, thereby reducing the shaking of the label.

[0023] Reference Figure 3 The adjustment assembly 8 includes a movable plate 801 mounted on the frame 1 through a bearing, the movable plate 801 is threadedly mounted with a threaded rod 802, the ends of the plurality of movable rollers 701 are mounted on the movable plate 801 through bearings, and the end of the movable plate 801 is connected to a hand wheel 803;

[0024] By adopting the above technical solution, the movable plate 801 is moved up and down by twisting the threaded rod 802, and the position of the movable roller 701 is adjusted to ensure the conveying tension of the label during detection.

[0025] The implementation principle of a label printing quality inspection machine in an embodiment of the present application is as follows: the label passes through the two label stabilization components 7 below the dust collection component 5 from the label supply tray 2 in sequence, passes through the conveyor shaft 4 below, and then passes through the label stabilization component 7 below the label detection camera 6 in sequence, and then passes through the conveyor shaft 4 as needed, and finally is connected to the label winding disk 3. When working, the vacuum cleaner 501 and the label detection camera 6 are started. When the label passes through the dust collection plate 502, the dust on the surface of the label is sucked out under the action of negative pressure. The label detection camera 6 detects the printing quality of the label, and uses the flexible sponge on the movable roller 701 and the fixed roller 702 to clamp the label, thereby increasing the friction between the label and the base paper, thereby preventing the label from sliding or shaking during the transmission process. The movable plate 801 is moved up and down by twisting the threaded rod 802, and the position of the movable roller 701 is adjusted to ensure the conveying tension of the label during detection.
