Description

Technical Field

[0001] This invention relates to the technical field of double-layer self-adhesive labels and labeling devices, and particularly to a double-layer combined printed self-adhesive label and labeling device. Background Technology

[0002] Double-layer labels are brief labels used to indicate information such as the name, weight, volume, and purpose of an item.

[0003] Labels have a certain degree of uniqueness and specificity. When workers mistakenly stick labels onto other products, they need to tear off the incorrectly pasted labels and re-paste them. However, the adhesion of existing labels after tearing them off and re-pasting them onto the products is poor, and they may not stick firmly. Furthermore, the length of existing labels is fixed after production. When pasting some thickened cylindrical products (such as long strips of wire rollers, construction rollers, etc.), since the label length is fixed, it may be impossible to wrap and stick the cylindrical products well.

[0004] The common method for applying double-layer labels is to manually pinch them together. However, manual operation can lead to misalignment of the labels and low production efficiency. Therefore, double-layer labeling devices have been developed. However, existing labeling devices have poor applicability and may cause air bubbles to appear at the label application point when applying double-layer labels. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This invention utilizes a special folding structure in the folding area of ​​the label. When a thinner roller needs to be pasted, there is no need to stretch the label. When a thicker roller needs to be pasted, the label can be stretched by a machine. After stretching, the label can be pasted onto rollers of different thicknesses. This allows one label to be pasted onto rollers of various thicknesses. Furthermore, the positioning ring on the surface of the label can cooperate with the positioning and fixing ring in the machine, reducing the possibility of misalignment between the two pasting areas during the pasting process.

[0018] 2. This invention uses an adhesive block and adhesive layer at the bottom of the label. In special circumstances where the label needs to be re-attached, the adhesive layer on the ground loses its stickiness after a regular label is torn off. However, after this label is torn off, although the original adhesive area loses some stickiness, the adhesive layer and the area where the adhesive block and the adhesive block meet still remain sticky, allowing the label to be re-attached.

[0019] 3. This invention utilizes a labeling clamping assembly that works in conjunction with an upper clamping layer. The sealing plate and bubble sheet of the labeling clamping assembly can adsorb the label, and the positioning ring can cooperate with the positioning ring of the label. When the label's pasting areas are about to be pasted together, the curved and protruding bubble sheet causes the center of the pasting areas to be pasted together first, reducing the possibility of misalignment between the two pasting areas and the formation of air bubbles during the pasting process. Furthermore, when pasting rollers with larger radii, the air extraction shell can be expanded outwards to allow pasting of larger rollers. The device has high integration and can paste rollers of various thicknesses.

[0020] 4. The present invention uses a trigger rod in the clamping roller assembly to cooperate with the roller to which the label is to be applied. When the roller presses the trigger rod, the trigger rod moves downward, and the clamping roller assembly can clamp the roller. Compared with the original method of manually holding the rod to apply the label, this device has higher integration and does not require an external power supply, thus enabling the device to clamp and lock cylindrical products.

[0053] Simultaneously, the label machine 5 is electrically connected to the controller and operates. The transmission roller 502 and the waste paper roll 504 rotate together, driving the label to rotate. When label 1 reaches the labeling table 503, the label machine 5 stops rotating. The first electric slider 602 is electrically connected to an external power source. The labeling clamping assembly 9 is moved to directly above the labeling table 503 by the movement block 601. The labeling clamping assembly 9 descends along the guide rail of the fixed table 603, connecting the vacuum pump to the suction port 912. The positioning fixing ring 910 will first adsorb and position the positioning ring 201 on the label 1. The vacuum pump starts under the control of the controller. When the vacuum pump is connected to the vacuum housing 906, the holes on the surfaces of the sealing plate 908 and bubble plate 909 begin to draw air out under the action of the vacuum pump. The two sets of sealing plates 908 and bubble plates 909 align with the label 1's pasting area 2 and adsorb the label 1. The controller controls the lifting platform 901 to rise, and the first electric slider 602 rotates, driving the moving block 601 to move. The moving block 601 drives the labeling clamping assembly 9 to move to the labeling position of the cylindrical product. If the diameter of the cylindrical product is large, the controller controls the vacuum housing 906 to expand outward on the guide rail 905, and the label 1 is placed on the sealing plate 908 and bubble plate 909. Under the suction and traction of label 1, the label unfolds, allowing it to fit cylindrical products of different sizes. Labeling clamping assembly 9 descends, and roller block 919 immediately contacts the cylindrical product. Pulling motor 915 pulls the pull reset rod 916, which in turn pulls the pull block 917 upwards. Pull block 917 pulls the pull rod 914, which in turn pulls the clamp housing 904. Under the pull of the pull rod 914, clamp housing 904 rotates around the hinge connection point of connecting block 903, causing the two clamp housings 904 to clamp inwards. As the outer casing 904 clamps inward, the label 1, driven by the action, also begins to fold and wrap around the side wall of the cylindrical product. When the adhesive areas 2 of the label 1 are about to be glued together, the bubble wrap 909, being curved and protruding, causes the center of the adhesive areas 2 to be glued together first. This reduces the possibility of misalignment between the two adhesive areas 2 and the formation of air bubbles during the adhesive process. The outer casing 904 of the clamp continues to clamp inward, and the bubble wrap 909 contracts inward under force. The clamp spring 911 abuts against the bubble wrap 909 and is compressed under force, thus completing the adhesive application of the label 1 to the cylindrical product.

[0054] After label 1 is affixed to the cylindrical product, the controller controls the pull rod motor 915 to operate, pulling the reset rod 916 downwards. The pull block 917 resets under the contact of the reset rod 916. The pull block 917 moves downwards, driving the pull rod 914. The pull rod 914 abuts against the clamp housing 904 outwards, expanding it outwards. After both clamp housings 904 reset, the lifting platform 901 rises and resets. The second electric slider 606 operates, driving the second moving platform 604 and the third moving platform 605 to move towards one end closer to the transport mechanism 8. At this time, the transport motor 801 operates, driving the transport roller 802 to rotate. The rotation of the transport roller 802 simultaneously drives the transport belt 803 to rotate. The transport belt 803 drives the upper transport block 804 to move. The cylindrical product clamped by the clamping roller assembly 10 is inserted into the groove of the transport block 804 under the control of the controller. The controller controls the second electric slider 606 to operate, and the third moving platform 605 moves under the second electric slider 606. Driven by the movement, the second moving stage 604 stops moving when it comes into contact with the limiting pin on the side wall of the lower compartment. The second electric slider 606 will continue to move forward until the cylindrical product is fully inserted into the transport block 804. The electric roller 805 inside the transport block 804 will have the effect of pulling out the clamped cylindrical product. When the cylindrical product is on the transport block 804, the transport motor 801 operates under the control of the controller, transporting the cylindrical product to the designated position. At this time, the trigger rod 1007 is not under gravity, the compression spring 1008 contracts, and drives the connecting slider 1002 upward. The upward displacement of the connecting slider 1002 will drive the support rod 1003 upward. The support rod 1003 drives the Y bracket 1004 to expand outward. The fixing clamp 1006 is reset under the action of the Y bracket 1004 and the support rod 1005. The second moving stage 604 and the third moving stage 605 are reset under the action of the controller of the second electric slider 606.

[0055] When it is necessary to re-attach label 1 under special circumstances, manually tear open the adhesive area 2 of label 1 to separate the two adhesive areas 2. Adhesive block 1 209 and adhesive block 2 306 will separate from adhesive layer 1 208 and adhesive layer 2 305 due to the tearing action. After the adhesive area 2 is torn open, adhesive layer 1 208 and adhesive layer 2 305 on the surface may lose some of their adhesiveness, but the places where adhesive layer 1 208 and adhesive layer 2 305 were initially attached to adhesive block 1 209 and adhesive block 2 306 will still remain adhesive. Workers can then re-attach label 1 to the cylindrical product.
