Description

Technical Field

[0001] The utility model belongs to the technical field of label cutting, and in particular relates to a label cutting device. Background Art

[0002] A label is an additional identification information paper card or brand added to an object to facilitate search and positioning. With the development of production, companies have an increasing demand for various types of labels in quantity and higher requirements for label quality. Traditional label cutting machines usually use guide wheels and active wheels to drive the label body to move toward the cutting mechanism to quickly complete the label cutting operation. In order to improve the production quality of labels, a separate limit structure is usually set to limit the label in the height direction to prevent the label from bending or jumping during movement, which affects the production quality. In the continuous production process of labels, labels need to be replaced frequently. In order to facilitate the label to pass through the limit structure while ensuring the effect of the limit structure on the label, it is often necessary to reinstall and adjust the limit structure. In this process, the production efficiency of the label is easily affected. Utility Model Content

The label body 3 is in contact with both the driving wheel 6 and the driven wheel 702 and passes between the driving wheel 6 and the driven wheel 702. The driving wheel 6 is connected to a servo motor 21;

[0032] It should be noted that in this embodiment, a rotatable driven structure 7 is arranged in the feeding component 2, and the adjusting plate 703 of the driven structure 7 is limited by a compression knob 8 that can move in the vertical direction, so as to adjust the gap between the driving wheel 6 and the driven wheel 702. That is, only by adjusting the compression knob 8, the efficiency of replacing the label body 3 can be improved while ensuring the production quality of the label;

[0033] Further, the feeding assembly 2 further includes a bottom plate 201. One end of the bottom plate 201 is connected to the frame 9, and the other end is provided with a baffle 10 extending in the vertical direction. A rotation hole corresponding to the position of the rotation shaft 701 is formed in the baffle 10 for the driven structure 7 to rotate around the rotation shaft 701. The driving wheel 6 is connected to a bearing provided on the baffle 10. That is, the provided bottom plate 201 and baffle 10 support the driving wheel 6 and the driven structure 7, enabling the driven structure 7 to rotate around the rotation shaft 701;

[0034] In one embodiment, as Figure 2 shown, a connecting plate 11 is further provided at the top of the baffle 10.

[0035] In one embodiment, as Figure 1 shown, an adjustment hole corresponding to the position of the driven structure 7 is further formed in the baffle 10. An adjustment knob 12 connected to the side wall of the driven structure 7 penetrates through the adjustment hole. That is, the provided adjustment knob 12 facilitates the operator to significantly increase the gap between the driving wheel 6 and the driven wheel 702 by lifting the adjustment knob 12 upward after loosening the pressing knob 8, further facilitating the replacement of the label body 3;

[0036] In one embodiment, as Figure 1 shown, a label sensor 13 is further provided between the guiding idler wheel 4 and the feeding assembly 2. The label sensor 13 is electrically connected to the cutting structure 5 to output a cutting instruction to the cutting structure 5 after sensing that the label body 3 has been fed to a preset length. The provided label sensor 13 can identify the feeding amount of the label body 3 before the label body 3 passes through the feeding assembly 2. Compared with the conventional method of measuring through the driving wheel 6, it can avoid errors caused by the slipping of the driving wheel 6;

[0037] In one embodiment, as Figure 2 shown, the cutting structure 5 includes a cutting knife 501 and a driving component 502 electrically connected to the label sensor 13.

Compared with the traditional upper and lower blade structure, the replacement operation is simpler;

[0038] In one embodiment, as Figure 2 and Figure 3As shown in the figure, it further includes a horizontal limiting structure disposed between the feeding assembly 2 and the cutting structure 5. The horizontal limiting structure includes a limiting plate 14 installed on the bottom plate 201 and limiting blocks 15 located on both sides of the label body 3. The limiting blocks 15 are both disposed on the limiting plate 14, that is, the limiting blocks 15 disposed on the limiting plate 14 limit the horizontal direction of the label body 3 during feeding to prevent the label body 3 from shifting;

[0039] Furthermore, adjustment slots 16 are formed on the limiting plate 14. The limiting blocks 15 have adjustment blocks embedded in the adjustment slots 16. An activity block 17 connected to the adjustment block is disposed on the side of the limiting plate 14 away from the limiting blocks 15, that is, it is convenient to adjust the positions of the limiting blocks 15 on the limiting plate 14 to adapt to label bodies 3 of different sizes, thereby expanding its scope of application;

[0040] In one embodiment, the cutting structure 5 further includes a cutting platform 503 disposed on the frame 9.

A storage box 20 is installed at the bottom of the adsorption structure 19, that is, the vacuum adsorption assembly is communicated with the adsorption holes on the cutting platform 503 to perform vacuum adsorption on the label body 3 on the cutting platform 503. The adsorption structure 19 disposed on one side of the cutting platform 503 reciprocates horizontally. When it approaches the cutting platform 503 under the action of the displacement mechanism, the vacuum adsorption assembly pauses operation. The adsorption structure 19 sucks away the label body 3 by means of vacuum adsorption, and then approaches the storage box 20 under the action of the displacement mechanism and stops adsorption, so that the label body 3 drops into the storage box 20 for collection, that is, the vacuum structure and the vacuum adsorption assembly operate alternately, fixing the label body 3 during cutting, improving the cutting quality while preventing the label body 3 from falling due to force during the cutting process;
