Description

Technical Field

[0001] This utility model relates to the technical field of pressing mechanisms, and in particular to a pressing mechanism for a small box label paper gluing backing roller. Background Technology

[0002] The YB45 small box packaging machine boasts advantages such as high-quality packaged products, fast production speed, high production efficiency, and stable operation, making it a leading packaging machine model for major cigarette manufacturing enterprises nationwide. The label paper gluing mechanism is crucial for cigarette pack forming; its function is to apply latex liquid to the non-printed surface of the label paper to ensure a firm bond. The label paper gluing mechanism mainly consists of a gluing wheel, a gluing backing roller, and a cylinder. Its working process is as follows: When the equipment is running, the cylinder actuates, causing the gluing backing roller to press down. The gluing backing roller rotates in the opposite direction to the conveyor roller shaft. As the conveyor roller shaft rotates, the gluing wheel rotates together. When the gluing working surface of the gluing wheel rotates to face the gluing backing roller, the label paper enters the gap between the gluing wheel and the gluing backing roller and is conveyed forward. The glue on the gluing working surface of the gluing wheel is then applied to the forward-conveyed label paper.

[0003] However, in existing mechanisms, the low cylinder pressure during operation prevents the adhesive coating roller from properly compacting the label paper, resulting in paper movement and unstable adhesive dots on the label paper—some areas are coated while others are not, severely impacting product quality. Furthermore, because the centrifugal force of the adhesive coating roller is opposite to the cylinder's pulling force, the cylinder needs to provide additional force to counteract this centrifugal force, accelerating cylinder fatigue and shortening its lifespan.

[0004] Therefore, improving the mechanism and developing a new type of label paper coating and backing roller pressing mechanism has become a problem that needs to be solved. Utility Model Content

[0018] The above-mentioned technical solution of this utility model has the following beneficial effects:

[0027] A small box label paper gluing backing roller pressing mechanism includes: a power drive assembly and a backing roller actuation assembly. Details are as follows:

[0028] The power drive assembly is located on one side of the protective cover 3, which consists of two steel plates with a gap between them, fixed to the machine. The power drive assembly includes: a base bracket 1, a cylinder base 2, a cylinder 4, a connecting sleeve 8, a limit block 9, and a set screw 10. Wherein:

[0029] The base bracket 1 and the limiting block 9 are fixed to the protective cover 3. Specifically, the base bracket 1 and the limiting block 9 are fixed to the protective cover 3 by bolts or welding.

[0030] One side of the cylinder base 2 is connected to the base bracket 1 via a connecting pin, and the other side is connected to the cylinder 4. Specifically, the base bracket 1 has a through hole and a groove, and the cylinder base 2 is provided with a rigid sleeve 14. The positions of the rigid sleeve 14, the groove, and the through hole are matched and fixed by connecting pins.

[0031] The front end of the cylinder push rod 5 of cylinder 4 is connected to the connecting shaft 7 via a connector 6, and the end of the connecting shaft 7 is fixedly connected to the connecting sleeve 8. Specifically, cylinder 4 is a single-acting cylinder with a diameter of 32mm, which provides greater thrust. Preferably, the end of the cylinder push rod 5 is connected to the connector 6 via a thread, and the connector 6 and the connecting shaft 7 are circumferentially fixed via a keyway or thread. Of course, the connection method in this application is not limited to this.

[0032] A fixing groove is provided in the center of the connecting sleeve 8 along its long axis, and the ends of the connecting shaft 7 and the inner column 11 of the anti-roller are both fixed in the fixing groove. Specifically, the ends of the connecting shaft 7 and the inner column 11 of the anti-roller are embedded in the fixing groove of the connecting sleeve 8 and fixed by set screws or clamping. The connecting shaft 7 and the inner column 11 of the anti-roller are located on the left and right sides of the fixing groove, respectively.

[0033] One end of the set screw 10 is connected to the connecting sleeve 8, and the other end forms a limiting fit with the bottom surface of the limiting block 9 in the vertical direction. Specifically, one end of the set screw 10 is screwed into the threaded hole of the connecting sleeve 8, and the other end forms a limiting fit with the bottom surface of the limiting block 9 in the vertical direction. In use, when the set screw 10 contacts the limiting block 9, the backing roller 13 is in its lowest position, and at this time the distance between the backing roller 13 and the glue-applying roller is equal to the thickness of the label paper.

[0034] The lining roller actuation assembly, located on the other side of the protective cover 3, includes: an inner column 11 for the lining roller, an inner column sleeve 12 for the lining roller, and a lining roller 13. Wherein:

Of course, this application is not limited to this, and those skilled in the art can choose a suitable connection method as needed.

[0036] The method of using the adhesive coating roller pressing mechanism for the small box label paper in this application is as follows:

[0037] When the equipment is running, the cylinder actuates, causing the set screw to contact the limit block, which presses down the glue-applying roller. The glue-applying roller and the conveyor roller rotate in opposite directions. As the conveyor roller rotates, the glue-applying wheel rotates together. When the glue-applying working surface of the glue-applying wheel rotates to be opposite the glue-applying roller, the label paper just enters the gap between the glue-applying wheel and the glue-applying roller and is conveyed forward. The glue on the glue-applying working surface of the glue-applying wheel will be applied to the forward conveyed label paper.

[0038] Although the present invention has been disclosed above with reference to embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various different choices and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention is defined by the claims and their equivalents.
