Technical Field

[0001] The utility model relates to the technical field of plastic barrel labeling, in particular to an automatic labeling machine for plastic barrels. Background Art

[0002] Plastic drum labeling is a common method of product packaging, intended to provide product information, brand identification, or warning instructions. The choice of labeling material depends on the labeling method, product characteristics, and environmental requirements. Common labeling materials include self-adhesive paper, PVC, PET, and synthetic paper. These materials have different properties, such as waterproof, oil-resistant, acid- and alkali-resistant, and abrasion-resistant, to meet different usage requirements. Appropriate labeling equipment is required to apply the labels.

[0003] The existing patent document "CN210882965U A labeling machine for plastic barrels" discloses a labeling machine. Although the labeling machine in the above technical solution can label plastic barrels, the outer wall of the plastic barrel is usually arc-shaped.

[0036] See also Figure 1-5 As shown, an automatic labeling machine for plastic barrels, the automatic labeling machine for plastic barrels comprises:

[0037] A driving cylinder 1, wherein a fixing cylinder 2 is fixedly provided at the front end of the driving cylinder 1, wherein an inner cavity is provided inside the fixing cylinder 2, and a return spring 4 is slidably connected to the inner cavity of the fixing cylinder 2, and a label suction seat 5 is fixedly provided at the front end of the return spring 4, and the label suction seat 5 is used to fix the label 10;

Furthermore, in order to solve the problem in the prior art that the side of the label is not easily warped due to insufficient adhesion force under cold temperatures in winter, the utility model is designed with a heating component 9. Through the setting of the heating component 9, the label can be automatically heated when it is smoothed, thereby effectively improving the adhesion force of the label and reducing the phenomenon of insufficient adhesion force due to temperature drop.

[0041] One end of a movable cylinder 3 is fixedly provided at the front end of the fixed cylinder 2 , and the other end of the movable cylinder 3 is fixedly connected to the label suction seat 5 .

[0042] The label suction seat 5 is provided with an inner cavity, and a plurality of small holes 6 are provided on the side wall of the label suction seat 5. One end of a connecting hose 7 is fixedly connected to the inner cavity of the label suction seat 5, and the other end of the connecting hose 7 is connected to an air pump. According to the technical solution, the air pump can continuously suck gas through the operation of the air pump, thereby forming an adsorption force on the surface of the label suction seat 5, and can adsorb and fix the label to be labeled, so that the label can be moved by the operation of the driving cylinder 1, so that the label is attached to the barrel wall of the plastic barrel;

[0043] The side smoothing assembly 8 includes a fixing frame 801, a swing arm 802, a rotating pressure roller 803, a connecting seat 804, a connecting spring 805 and a fixing platform 806. The fixing frames 801 are fixedly provided on both sides of the fixed cylinder 2. The front end of the fixing frame 801 is rotatably connected to the swing arm 802. The rotating pressure roller 803 is rotatably connected to one end of the swing arm 802.

[0044] The other end of the swing arm 802 is rotatably connected to a connecting seat 804 , one end of a connecting spring 805 is fixedly connected to a side wall of the connecting seat 804 , and the other end of the connecting spring 805 is fixedly connected to a fixing platform 806 ;

[0045] The fixing platform 806 is fixedly arranged at the front end side wall of the driving cylinder 1. Through the technical solution, after the label suction seat 5 absorbs the label 10, it pushes the label 10 to fit on the bucket body. During the fitting, the driving cylinder 1 can continue to push the fixing cylinder 2 to move, thereby driving the fixing frame 801 and the swing arm 802 to move forward, driving the rotating pressing roller 803 to move forward, so that the rotating pressing roller 803 is pressed tightly on the side of the label 10, and the rotating pressing roller 803 rolls along the curved outer wall of the bucket body, thereby pressing and smoothing the side of the label, so that the label is fully fitted with the outer wall of the bucket body, avoiding the phenomenon of warping, and is particularly suitable for labeling operations on the curved outer wall of the bucket;

[0046] The rotating pressing roller 803 includes a circular roller body 8031 and air outlet holes 8032. The circular roller body 8031 is provided with an inner cavity. The inner cavity wall of the circular roller body 8031 is provided with a plurality of air outlet holes 8032.

One end of the guide rod 903 is fixedly connected to the side wall of the movable piston 902. The other end of the guide rod 903 passes through the inner cavity side wall of the connecting cylinder 901 and extends outside the wall. One end of the guide rod 903 is fixedly connected to the inner cavity side wall of the movable cylinder 3. Through this technical solution, when the labeling operation is performed, after the label contacts the barrel body, the driving cylinder 1 continues to push forward, which will cause the movable cylinder 3 to retract and move into the inner cavity of the fixed cylinder 2, thereby driving the guide rod 903 to move;

[0048] A heating resistance wire 904 is fixedly arranged in the inner cavity of the connecting cylinder 901. The heating resistance wire 904 can heat the gas in the inner cavity of the connecting cylinder 901.

[0049] One end of the gas hose 905 is fixedly connected to the inner cavity of the connecting cylinder 901, and the other end of the gas hose 905 extends into the inner cavity of the round roller body 8031 and is fixedly connected to 9031. Through this technical solution, when the guide rod 903 moves, it can drive the movable piston 902 to move, thereby pushing the gas in the inner cavity of the connecting cylinder 901 to be transported and moved, so that the hot air is transported to the inner cavity of the round roller body 8031, and then when smoothing the label, the hot air can be output through the air outlet 8032 to heat the label, thereby avoiding the phenomenon of insufficient adhesion caused by the low temperature in winter.
