Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a gluing and pressing device for corrugated base paper production. Background Technology
[0002] Corrugated cardboard is a multi-layered laminate consisting of a corrugated core paper layer and one or more layers of cardboard. It has high mechanical strength and can withstand collisions and drops during handling. To ensure the bonding effect between the layers, an adhesive coating and pressing device is needed to press the glued layers together to firmly bond them together and give full play to the excellent performance of corrugated cardboard. In the production of corrugated base paper, a large amount of dust or particles easily adheres to the surface of the cardboard during transportation and storage. If not removed, it will affect the quality of adhesive coating and pressing. In addition, the glue may become stagnant in certain areas for a long time during storage and use, leading to sedimentation, which will also affect the quality of adhesive coating and pressing. Some advanced adhesive coating and pressing devices are designed with corresponding cleaning mechanisms and glue stirring or circulation mechanisms to solve these problems and ensure the production of high-quality corrugated cardboard.
[0003] The appropriate pressing pressure is crucial for corrugated board formation. Suitable pressure between the upper and lower corrugating rollers ensures good corrugation, standard flute shape, and maintains the strength of the cardboard. Inappropriate pressing pressure can cause the corrugations to flatten or tilt, reducing the flat crush strength and thickness of the cardboard, consequently lowering the edge crush strength. The compressive strength of the finished box will also fail to meet requirements. Only by adjusting the pressure appropriately can the glue be evenly distributed between the two layers of paper, firmly bonding them together to form high-quality corrugated cardboard. Current technology uses electric telescopic rods installed at the four corners of the hot press table in the pressing device. The extension and retraction of these electric telescopic rods are controlled by an electrical control box, thereby adjusting the distance between the top plate and the hot press table, thus changing the pressure applied to the base paper. However, this adjustment method suffers from motor failure and rod jamming with prolonged use, affecting the accuracy and timeliness of pressure adjustment. Furthermore, the adjustment precision of the electric telescopic rods is limited, failing to meet the needs of some corrugated base paper production processes requiring high pressure precision.

[0040] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 The coating assembly 303 includes a hollow shell 3031, the inner wall of which is fixedly connected to the outer wall of the rotating shaft 302, and a plurality of rolling balls 3032 are rotatably connected to the bottom of the outer wall of the hollow shell 3031. The feeding assembly 304 includes an observation window 3041, the inner wall of which is fixedly connected to the left side of the outer wall of the hollow shell 3031, and a feeding pipe 3042 is connected to the top front side of the outer wall of the observation window 3041. A plug 3043 is provided at the top of the feeding pipe 3042.
[0041] Specifically, the hollow shell 3031 is fixedly connected to the rotating shaft 302, ensuring the stability and durability of the component during operation. The ball 3032 plays a crucial role in the coating process, uniformly distributing pressure to ensure the uniformity and quality of the coating. The observation window 3041 is fixedly connected to the hollow shell 3031, allowing the operator to clearly observe every detail of the coating process. The stopper 3043 not only facilitates the filling and replacement of materials, but also allows the operator to precisely control the flow rate and speed of materials by adjusting the stopper 3043 to adapt to different coating requirements.
[0042] Working principle: Two pieces of paper are driven to the right along the upper and lower sides of the outer wall of the hollow shell 3031, thus concentrating the two pieces of paper into the gap between the rotating roller 2044 and the transmission roller 2063. The motor 2061 is started, which drives the rotating column 2062 and the transmission roller 2063 to rotate together, thereby squeezing the two pieces of paper together. Then, by rotating the rotating block 2052, the rotating block 2052 drives the threaded column 2051, so that the threaded column 2051 rotates along the inner wall of the fixed block 2041. Since the sliding column 2043 is threadedly connected to the threaded column 2051, the threaded column 2051 will cause the sliding column 2043 to slide down along the inner wall of the hollow groove 2042 during the rotation. This controls the gap between the rotating roller 2044 and the transmission roller 2063, thereby adjusting the pressure of squeezing the paper and realizing the pressing of the corrugated paper. It can also accurately control the pressure during pressing and improve the adhesion of the corrugated paper.
[0043] Two pieces of corrugated paper are placed on the top and bottom of the outer wall of the hollow shell 3031, respectively. The transmission on the right side pulls the paper to the right. As the lower piece of paper moves to the right, it drives the roller 3032 to rotate. The roller 3032 carries out the glue inside the hollow shell 3031 and evenly coats it on the surface of the paper, providing a foundation for subsequent pressing. The glue content inside the hollow shell 3031 can be observed through the observation window 3041. When it needs to be replenished, the stopper 3043 is opened and the glue is poured into the interior of the hollow shell 3031 along the feed pipe 3042. This achieves uniform coating of glue and allows for real-time monitoring of the glue content inside the hollow shell 3031, thus filling the hollow shell 3031.
[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
