Description

Technical Field

[0001] This utility model belongs to the technical field of bottle labeling mechanism, specifically relating to a self-preheating bottle labeling mechanism. Background Technology

[0002] Bottle labeling mechanisms typically achieve automated operation through mechanical and electrical control principles. For example, when a labeling photocell senses the arrival of a bottle, the PLC control center sequentially issues instructions such as label delivery, positioning, label cutting, and label injection to complete the labeling process. However, in existing bottle labeling mechanisms, when the bottle temperature is low and no preheating treatment is performed, the temperature difference between the label and the bottle causes the thermoplastic to shrink and rebound, resulting in adhesion bubbles.

[0003] These air bubbles not only affect the appearance quality of the product, but may also reduce the sealing performance of the packaging, thereby affecting the product's freshness preservation effect. To solve this problem, the bottle needs to be properly preheated to reduce the temperature difference between the label and the bottle.

[0004] Therefore, for the existing bottle labeling mechanism mentioned above, because the bottle body temperature is low and no preheating treatment is performed, the label and the bottle body will rebound and produce air bubbles due to the temperature difference causing thermoplastic shrinkage. A self-preheating bottle labeling mechanism can be designed. Utility Model Content

[0005] In order to overcome the problem that existing bottle labeling mechanisms, due to the low temperature of the bottle body and the lack of preheating treatment, cause the label and the bottle body to rebound and produce air bubbles due to the temperature difference causing thermoplastic shrinkage.

[0006] The technical solution of this utility model is as follows: a self-preheating bottle labeling mechanism, including a labeling machine, a preheating component, and a thermoplastic shrinking component; the preheating component is provided at the upper end of the labeling machine; the thermoplastic shrinking component is provided on one side of the labeling machine; the preheating component includes a preheating chamber, a dust cover, a handle, a filter element, a fan, and an electric auxiliary heating pipe; the thermoplastic shrinking component includes a thermoplastic shrink tunnel, a bottle conveyor, and a hot air blower.

[0007] Preferably, the fan of the preheating component draws in external air. The air is filtered and heated by the filter core and the electric auxiliary heating pipe before being blown onto the bottle body to preheat the bottle body and reduce the temperature difference between the bottle body and the label. The label is then further heated by the thermoplastic shrinkage component, which ensures that the label adheres tightly to the bottle body and completes the labeling function. This solves the problem of existing bottle labeling mechanisms, where the bottle body temperature is low and no preheating treatment is performed, causing the label to rebound and produce adhesion bubbles due to the temperature difference between the label and the bottle body after thermoplastic shrinkage.

[0008] Preferably, the upper end of the sleeve labeling machine is provided with a preheating bin, and the preheating bin is in sealing connection with the upper port of the sleeve labeling machine; the upper end of the preheating bin is provided with a dust cover, and the dust cover is integrally formed with the preheating bin.

[0009] Preferably, both sides of the dust cover are provided with handles, and the handles are fixedly connected with the upper end surface of the preheating bin.

[0010] Preferably, the lower end of the dust cover is provided with a filter element, and the filter element is in bolt sealing connection with the inner wall of the preheating bin; the lower end of the filter element is provided with a fan, and the shell of the fan is in bolt fixed connection with the inner wall of the preheating bin.

[0011] Preferably, the lower end of the air outlet of the fan is provided with an electric auxiliary heating pipe, and the electric auxiliary heating pipe is fixedly connected with the shell of the fan.

[0012] Preferably, one side of the sleeve labeling machine is provided with a thermoplastic shrinkage tunnel; the inside of the thermoplastic shrinkage tunnel is provided with a bottle conveying machine.

[0013] Preferably, the upper end of the thermoplastic shrinkage tunnel is provided with a hot air blower, and the blowing end of the hot air blower is arranged in the inside of the thermoplastic shrinkage tunnel.

[0014] The self-preheating type bottle sleeve labeling mechanism has the advantages that:

[0015] 1. The sleeve labeling mechanism of the existing bottle body does not undergo preheating treatment because the bottle body temperature is low, so that the temperature difference between the label and the bottle body causes rebound after thermoplastic shrinkage, resulting in the problem of adhesion bubbles. The fan of the preheating assembly inhales external air, and the inhaled air is filtered and heated by the filter element and the electric auxiliary heating pipe and then blown to the bottle body, so as to preheat the bottle body and reduce the temperature difference between the bottle body and the sleeve label. After further heating by the thermoplastic shrinkage assembly, the sleeve label is completely attached to the bottle body to complete the labeling function. The problem of adhesion bubbles caused by the temperature difference between the label and the bottle body after thermoplastic shrinkage is solved.

[0016] 2. The positioning groove for placing the bottle body is arranged on the conveying belt of the bottle conveying machine, so as to improve the stability of the movement of the bottle body. BRIEF DESCRIPTION OF DRAWINGS
