Description

Technical Field

[0001] The utility model relates to the technical field of corrugated board processing, and specifically relates to a corrugated board flattening and drying device. Background Technique

[0002] In the prior art, through retrieval, it is found that, for example, a Chinese patent (application number: 202223222333.8) discloses a corrugated board flattening and drying device. In the cardboard running direction, first, a cardboard flattening mechanism is used to flatten the cardboard, and then a cardboard drying mechanism is used to perform secondary drying and shaping on the cardboard, ensuring the quality of the cardboard. The cardboard flattening mechanism adopts multiple layers of stacked thin pressing rods. Compared with the easily thought-of pressing plate, the dense thin pressing rods can achieve an effect similar to that of the pressing plate, that is, to evenly flatten the surface of the cardboard. At the same time, the dense thin pressing rods can disperse the water vapor on the cardboard to each independent thin pressing rod, increasing the evaporation area of water and making it not easy to accumulate water. If a pressing plate is used, it is very easy to accumulate water and cause damage to the cardboard.

[0003] However, when the above-mentioned many thin pressing rods contact the corrugated board, the contact area is large, thereby increasing the friction between the two, and it is easy to get stuck when the corrugated board is conveyed. Moreover, when there are bubbles on the corrugated board, the freedom of the thin pressing rods up and down is restricted, and the corrugated board may also get stuck. Therefore, improvements are needed. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a corrugated board flattening and drying device, which solves the problems mentioned in the background technique.

[0005] To achieve the above purposes, the utility model is realized through the following technical solutions:

[0006] A corrugated board flattening and drying device includes a cardboard conveyor table. Along the cardboard running direction on the cardboard conveyor table, a cardboard flattening mechanism and a cardboard drying mechanism are successively arranged. The cardboard drying mechanism includes a hot air blower. The air outlet of the hot air blower faces upward and is communicated with a wind guide cylinder. The top opening of the wind guide cylinder is located at the edge of the top surface of the cardboard conveyor table and is in the shape of a long and narrow flat nozzle. The airflow blown out from the top opening of the wind guide cylinder flows parallel to the top surface of the cardboard conveyor table and perpendicular to the cardboard running direction.

[0007] The most main difference design of the utility model compared with the prior art is that: the cardboard flattening mechanism includes a flattening roller, and the flattening roller is installed on the cardboard conveyor table through a height adjustment structure.

[0008] Specifically, in the present utility model, the height adjustment structure includes two symmetrically arranged inclined rods. The lower ends of the inclined rods are installed on both sides of the cardboard conveying table. The flattening roller is installed between the two inclined rods through an elastic member. The elastic member is a spring, and the spring is sleeved on the inclined rod. An adjusting member and a mounting member are installed on the inclined rod. The adjusting member is located below the mounting member. The spring is located between the adjusting member and the mounting member. The flattening roller is rotatably installed between the two mounting members.

[0009] In order to realize the height adjustment of the flattening roller, an external thread is provided on the outer surface of the inclined rod, and the adjusting member is a nut threadedly installed on the inclined rod.

[0010] In order to realize the rotation of the flattening roller, the mounting member is a right-angle plate. A sliding hole slidably matched with the inclined rod is provided on one side plate of the right-angle plate. A bearing seat is installed on the other side plate of the right-angle plate. A bearing is rotatably installed on the bearing seat. The end of the flattening roller is fixed on the bearing.

[0011] Compared with the prior art, the present utility model has the following beneficial effects: By adopting the method of rotating and flattening the flattening roller, the friction between it and the corrugated cardboard is reduced. While ensuring the flattening of the corrugated cardboard, it prevents the corrugated cardboard from getting stuck and ensures the high-efficiency conveying of the corrugated cardboard.

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0018] Such as Figure 1As shown in the figure, the utility model provides a corrugated cardboard flattening and drying device, which includes a cardboard conveying table 1. Along the cardboard running direction on the cardboard conveying table 1, a cardboard flattening mechanism and a cardboard drying mechanism are successively arranged. The cardboard drying mechanism includes a hot air blower 2. The air outlet of the hot air blower 2 faces upward and is communicated with an air guiding cylinder 3. The top opening of the air guiding cylinder 3 is located at the edge of the top surface of the cardboard conveying table 1 and is in the shape of a long and narrow flat nozzle. The air flow blown out from the top opening of the air guiding cylinder 3 flows parallel to the top surface of the cardboard conveying table 1 and perpendicular to the cardboard running direction. The above structure is the prior art, and the specific drying principle of the corrugated cardboard will not be elaborated in the utility model.

[0019] As Figures 1-3 shown in the figure, compared with the prior art, the most important difference design of the utility model is that: the cardboard flattening mechanism includes a flattening roller 4, and the flattening roller 4 is installed on the cardboard conveying table 1 through a height adjusting structure.

[0020] As Figure 1 、 Figures 3-4 shown in the figure, specifically in the utility model, the height adjusting structure includes two symmetrically arranged inclined rods 5. The lower ends of the inclined rods 5 are installed on both sides of the cardboard conveying table 1. The flattening roller 4 is installed between the two inclined rods 5 through an elastic member. The elastic member is a spring 6. The spring 6 is sleeved on the inclined rod 5. An adjusting member 7 and a mounting member 8 are installed on the inclined rod 5. The adjusting member 7 is located below the mounting member 8. The spring 6 is located between the adjusting member 7 and the mounting member 8. The flattening roller 4 is rotatably installed between the two mounting members 8.

[0021] As Figures 3-4 shown in the figure, in order to realize the height adjustment of the flattening roller 4, an external thread is provided on the outer surface of the inclined rod 5, and the adjusting member 7 is a nut threadedly installed on the inclined rod 5.

[0022] As Figure 4 shown in the figure, in order to realize the rotation of the flattening roller 4, the mounting member 8 is a right-angle plate. A sliding hole slidably matched with the inclined rod 5 is opened on one side plate of the right-angle plate. A bearing seat 9 is installed on the other side plate of the right-angle plate. A bearing is rotatably installed on the bearing seat 9. The end of the flattening roller 4 is fixed on the bearing.

[0023] Next, the working principle of the present utility model will be described in detail: First, according to the thickness of the corrugated cardboard, the nut is rotated up and down, so that the nut moves up and down along the inclined rod 5. Furthermore, through the sliding fit of the spring 6 and the right-angle plate with the inclined rod 5, the flattening roller 4 is driven to move up and down, realizing the height adjustment of the flattening roller 4, and making the lowest point of the flattening roller 4 abut against the corrugated cardboard. When the corrugated cardboard is conveyed, due to the friction between it and the flattening roller 4, the flattening roller 4 rotates, reducing the friction between the two, thus preventing the corrugated cardboard from getting stuck. Moreover, if there are bubbles on the corrugated cardboard, the flattening roller 4 is slightly tilted regularly. Through the action of the spring 6, the flattening roller 4 can perform a certain jitter, preventing the flattening roller 4 from getting stuck again. Secondly, the setting of the flattening roller 4 can prevent the corrugated cardboard from warping after passing under it. Then, after the flattening roller 4 contacts the corrugated cardboard, it takes away the moisture. During the rotation of the flattening roller 4, the water seal is evaporated, prolonging the moisture evaporation time, so that when the flattening roller 4 contacts the corrugated cardboard, it is in a dry state.

[0024] Finally, the most important contribution of the present utility model is: adopting the method of rotating and flattening the flattening roller 4 to reduce the friction between it and the corrugated cardboard, ensuring the flattening of the corrugated cardboard while preventing the corrugated cardboard from getting stuck and ensuring the high-efficiency conveyance of the corrugated cardboard.

[0025] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
