Description

Technical Field

[0001] The utility model relates to the technical field of cigarette packaging, in particular to a self-cleaning device for a glue coating backing roller of a packaging machine. Background Art

[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.

[0003] At present, since cigarettes need to be packaged in small boxes and strips of paper before they can be put on the market, the small box packaging paper needs to pass through the conveying channel between the latex coating roller and the contrasting roller during the conveying process. During the conveying process, the non-printing surface of the small box is coated with a certain amount of latex under the action of the coating roller and the contrasting roller, and then fixed into shape after a series of folding and drying. The completion of the gluing action on the non-printing surface of the small box requires the cooperation of the contrasting roller and the gluing roller controlled by the cylinder. In the actual production process, due to the long-term continuous operation of the glue coating wheel, after the upper station smoke group is removed, the small box packaging paper stops supplying, but the glue coating roller and the counter roller continue to rotate. Although there is a certain gap between the two, as the glue coating roller runs for a long time, the latex temperature increases and the latex viscosity decreases, so that some latex will be splashed onto the counter roller. At the same time, the small box packaging paper is not delivered in place, which may easily cause glue scale to accumulate on the upper part of the counter roller. The accumulated glue scale will cause the printed surface of the small box packaging paper to be dirty, forming a quality hazard. Furthermore, the glue scale will have a certain impact on the delivery of the small box packaging paper, causing the small box packaging paper to be skewed, causing equipment shutdown failure, and affecting production efficiency. For this reason, the operator needs to continuously clean the glue scale on the counter roller to avoid excessive accumulation of glue scale on the counter roller, reduce quality risks, and improve equipment operation efficiency.

[0004] To solve the above problems, some cigarette manufacturers have improved the glue wheel, reducing the amount of glue carried by the glue wheel of the small box packaging paper during rotation to avoid splashing caused by excessive latex on the glue wheel. However, this method is likely to cause quality risks of poor adhesion of the small box. Some manufacturers apply paraffin wax on the backing roller to improve the surface smoothness of the backing roller to avoid the accumulation of glue scale or dust. However, applying paraffin wax directly to the backing roller will cause oil accumulation on the printing surface of the small box packaging paper due to uneven application, resulting in product quality problems.

[0005] In order to solve the problem of accumulated glue scale on the counter roller, the existing technology, such as patent (CN202020486939.4), sets a plurality of gluing grooves on the arc surface of the gluing roller, sets a plurality of glue pressing bumps on the arc surface of the counter roller, and the gluing grooves and the glue pressing bumps correspond to each other and mesh with each other, thereby reducing the surface area of ​​the counter roller, thereby increasing the gap between the gluing wheel and the counter roller. However, this method causes the quality of gluing of the small box packaging paper to decrease, and easily causes the amount of glue applied to the pasting part of the inner frame paper of the small box to decrease, resulting in quality problems such as poor pasting of the packaging paper. Another example is patent (CN201721230229.X) to install a cleaning brush on the upper part of the counter roller, but it is directly installed at both ends of the upper part of the counter roller. The device is complicated to disassemble and install the brush, and the replacement time is long. The machine needs to be stopped to replace the brush, which is not conducive to on-site operation, and smoke and dust cannot be cleaned in time. Utility Model Content

A rotating shaft 81 is set between the two side plates 82, and one end of the support rod 4 is rotatably connected to the rotating shaft 81, so that the support rod 4 can rotate 180 degrees around the rotating shaft 81.

[0044] Optionally, the other end of the support rod 4 is connected to the fixing frame 2 by snapping to form a snap-fit ​​structure, and the snap-fit ​​structure can adopt a conventional snap-fit ​​structure in the art, preferably, a snap-fit ​​member 9 is provided, and the snap-fit ​​member 9 is a U-shaped structure, and a protruding spring sheet is provided on the opposite side of the two side walls of the snap-fit ​​member 9, and the distance between the two protruding spring sheets at the closest point in the natural state is less than the diameter of the support rod 4 at the corresponding position. When the support rod 4 is snap-fitted with the snap-fit ​​member 9, a downward force is applied to the support rod 4, and the protruding spring sheets of the snap-fit ​​member 9 move away from both sides under the lateral pressure of the support rod 4, so that the support rod 4 moves downward, and the protruding spring sheets of the snap-fit ​​member 9 are restored, thereby clamping the support rod 4.

[0045] Optional, such as Figure 4 As shown, the support rod 4 includes a fixed section 41 and a movable section 42 , the fixed section 41 and the movable section 42 are connected by threads, the fixed section 41 is hinged to the fixed frame 2 , and the movable section 42 is snap-connected to the fixed frame 2 .

The shaft sleeve 5 is rotatably connected to the support rod 4. The brush 7 is fixed on the shaft sleeve 5, and the brush 7 and the shaft sleeve 5 are detachably connected.

[0047] Optional, such as Figure 5 As shown, multiple axial spring pieces 6 are fixedly connected to the outside of the sleeve 5, and the axial spring pieces 6 abut against the cylindrical bristle fixing wall 72 to fix the brush 7 on the sleeve 5. Preferably, four axial spring pieces 6 are arranged on the outside of the sleeve 5, each axial spring piece 6 is arranged along the axial direction of the sleeve 5, and the four axial spring pieces 6 are evenly arranged along the arc surface of the sleeve 5 to accurately fix the brush 7.

Here, the air holes 12 are preferably arranged obliquely relative to the glue-coating reverse roller 3, so that an air film is formed on the surface of the glue-coating reverse roller 3. When no packaging paper passes, the colloid thrown out by the glue-coating roller changes direction under the action of the air film to prevent it from adhering to the glue-coating reverse roller 3. When the packaging paper passes, the air holes 12 spray high-pressure gas to prevent the packaging paper from adhering to the glue-coating reverse roller 3, which is conducive to the rapid passage of the packaging paper. At the same time, the obliquely arranged air holes can prevent the high-pressure gas from blowing directly toward the glue-coating roller, causing the colloid to splash.
