Description

Technical Field

[0001] This utility model relates to the field of automated label application technology for packaging, and more specifically to an online adhesive removal device. Background Technology

[0002] In container packaging production lines where flexible labels need to be affixed, adhesives are generally used to attach the flexible labels to the required locations on the containers.

[0003] When the labeling equipment reaches a certain capacity, the inherent properties of the adhesive and the rotation of the equipment parts cause the adhesive to continuously diffuse. Over time, the surrounding parts, such as the labeling drum assembly, and even the environment become filled with increasingly concentrated adhesive, which can damage the normal operation of the labeling drum assembly. At this point, it is necessary to slow down, stop the machine, and manually clean the diffused adhesive particles with a cleaning agent, thus limiting the full performance of the labeling drum assembly and causing certain costs and waste. Moreover, manual cleaning is inefficient, and the chemical properties of the adhesive are not conducive to the protection of workers. Utility Model Content

[0039] In the embodiment of the online adhesive removal device, in specific use, the cleaning surface can utilize appropriate friction to achieve the technical effect of automatically removing adhesive residue particles from the label application drum.

[0040] Example 2

[0041] The adhesive online removal device in this embodiment has the same basic structure as in Embodiment 1, but differs or is improved in the following ways: Figure 1 , 2 As shown in Figures 3 and 4, the cleaning roller assembly 3 also includes an air blowing pipe. The air blowing pipe has air jet holes facing the label coating drum annular surface 71. The air blowing pipe is axially fixed to the inner side of the cleaning roller seat 31 and connected to an external high-pressure air source. Compressed air can be used to quickly dry the label coating drum annular surface 71, ensuring the label coating drum surface remains clean and dry at all times. This eliminates the downtime required for manual cleaning and prevents the accumulation of adhesive particles in the working environment, significantly improving the overall efficiency of the equipment and facilitating high-speed production. At least two air blowing pipes are arranged side-by-side to improve drying efficiency, such as air blowing pipe 33 and air blowing pipe 32 arranged side-by-side. An adhesive scraper 36 is also laterally fixed to the inner side of the cleaning roller seat 31, with its scraping surface facing the label coating drum annular surface 71. The brush of the cleaning roller 32 and the adhesive scraper 36 work together to thoroughly remove adhesive residue. Figure 2 , 4As shown in Figure 5, the adhesive scraper 36 passes through the cleaning roller seat 31 and is fixedly connected to the angle adjustment plate 35. One end of the angle adjustment plate 35 has an arc-shaped adjustment hole, and the other end has a rotating hole. The side wall of the cleaning roller seat 31 has a long hole larger than the width of the adhesive scraper 36, which matches the adjustment range of the arc-shaped adjustment hole. A fixing bolt 38 is connected inside the arc-shaped adjustment hole. The air blowing pipe 32 is rotatably connected to the rotating hole. When adjusting the angle of the adhesive scraper 36, the angle adjustment plate 35 is rotatably connected to the air blowing pipe through the rotating hole.

[0042] An arc-shaped hole is provided on the flange face of the adjusting flange 14 to adjust the installation angle of the cleaning roller assembly 3; preferably, the rotation relationship between the rotary cantilever 15 and the fixed shaft 12 is controlled by the handle 13, which is convenient and labor-saving.

[0043] The adhesive online removal device of this embodiment is applied to a beverage container post-packaging production line. The production line includes an adhesive storage assembly 9, an adhesive coating assembly 6, and a label coating drum assembly 7, which are distributed according to the adhesive flow direction in the prior art. Adhesive particles are easily generated on the coating drum annular surface 71 in the label coating drum assembly 7. In order to ensure the normal operation of the label bonding to the container, the adhesive particle residue removal process is as follows:

[0044] The cleaning agent is atomized through the atomizing nozzle and sprayed onto the label covering drum ring surface 71 after reaching the set requirements. The cleaning roller 32 is driven by the servo motor 4. The control system controls the cleaning roller 32 to match a reasonable linear speed difference with the label covering drum. The two rotate in the same direction at the contact surface, and the friction of the contact surface removes the adhesive from the label covering drum ring surface 71. Then, the air blowing pipe 33 uses compressed air to blow air onto the label covering drum to quickly dry the contact points. In this way, the label covering drum is always in working condition.

[0045] The brushes fixed to the surface of the cleaning roller 32 are made of a tough, rigid, and wear-resistant material, with different models selected according to the usage cycle. The cleaning roller 32 is covered with a protective cover. The cleaning roller 32 rotates in both directions according to the settings. Generally, it rotates in the same direction as the label covering drum to remove the tiny adhesive particles remaining on the label covering drum. However, sometimes the residue may stick tightly to the label covering drum and form hard clumps. In this case, the cleaning roller 32 needs to rotate in reverse. The brush-like parts on it and the adhesive scraper 36 work together to lift the hard clumps, making the removal easier. The two rotation times are coordinated by controlling the servo motor and set according to the on-site working conditions to achieve the purpose of timely removal of adhesive residues.

[0046] As the cleaning roller 32 continues to operate, adhesive residue will accumulate on the cleaning roller 32 itself. At this time, the air blowing pipe 33 can start working as a self-cleaning part to scrape off the residual dirt and blow it away in time.

[0047] The operating cycle and time of this device are set according to the needs of the equipment, and are programmed by the control system. During operation, the equipment speed is adjusted as needed, generally by reducing the speed, and the extent of the speed reduction is determined based on the specific operating conditions.

[0048] The operating cycle of this device is cyclical, with adjustments made within a time frame of 1 / 2 min to 2 / 3 min.

[0049] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention. The actual structure and manufacturing steps are not limited to these. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
