Description

Technical Field

[0001] This utility model relates to the field of paperboard preparation technology, and in particular to a rapid hot paperboard cooling device. Background Technology

[0002] In the continuous production process of paperboard, the hot paperboard needs to be cooled so that it is less likely to bend or warp during subsequent cutting.

[0003] Current methods for cooling hot paperboard include external surface air cooling, internal ventilation, and cold roll cooling.

[0004] External surface air cooling refers to the use of a fan to quickly blow air onto the surface of the hot cardboard during the continuous conveying process, in order to rapidly cool the hot cardboard.

[0005] Internal ventilation is mainly applicable to corrugated cardboard. It involves blowing air into the corrugated core layer of the cardboard to quickly cool the hot corrugated cardboard, such as the cardboard cooling and setting machine disclosed in Chinese Utility Model No. CN219338798U.

[0006] Cold roll cooling uses rollers that can be circulated with a refrigerant. While conveying the hot paperboard, the rollers rapidly cool the paperboard. This cooling method combines paperboard traction and cooling and is widely used. However, cold roll cooling requires a corresponding refrigeration system, resulting in higher purchase and production costs, and therefore needs improvement. Utility Model Content

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figure 1-2 A rapid-type hot cardboard cooling device includes a mounting frame 1, a cardboard support roller 2, a water storage container 3, and a water removal mechanism 4.

[0037] The cardboard support roller 2 is rotatably connected to the mounting frame 1. The cardboard support roller 2 is horizontally set, and the outer circumferential surface of the cardboard support roller 2 forms an upper part 201 and a lower part 202 when rotating.

[0038] In the positive rotation direction of the cardboard support roller 2 (e.g.) Figure 1 On the clockwise rotation, the outer circumferential surface of the cardboard support roller 2 also forms a roller middle section 203 when rotating. The roller lower section 202, roller middle section 203, and roller upper section 201 are arranged sequentially along the positive rotation direction of the cardboard support roller 2.

[0039] The upper part of the water storage container 3 has a roller inlet, and the lower part 202 of the cardboard supporting roller is inserted into the water storage container 3 through the roller inlet so that when the water storage container 3 is storing water, the lower part 202 of the roller is in contact with the water in the water storage container 3. When the temperature of the cardboard supporting roller rises, a water cooling system can be set up accordingly.

[0040] The water removal mechanism 4 is configured to remove surface water from the middle part of the roller.

[0041] In this embodiment, by water-cooling the outer surface of the cardboard support roller 2, the cardboard support roller 2 can be cooled down quickly, thereby effectively cooling the hot cardboard 100. Furthermore, the water removal mechanism 4 removes water adhering to the outer surface of the cardboard support roller 2, preventing direct contact between water and the hot cardboard 100 and ensuring the quality of the hot cardboard. This rapid hot cardboard cooling device uses water as the refrigerant, resulting in lower purchase and operating costs.

[0042] In some embodiments, the water removal mechanism 4 includes a scraping mechanism 41, which is used to brush water onto the surface of the middle part 203 of the cardboard support roller to remove surface water from the middle part 203 of the roller.

[0043] In some embodiments, the wiper mechanism 41 includes a wiper strip connecting bracket 411 disposed on a mounting frame, and a wiper strip 412 that contacts the center of the roller 203 is connected to the wiper strip connecting bracket 411.

[0044] Preferably, the squeegee strip 412 extends along the axial direction of the cardboard support roller 2 to more comprehensively squeegee water from the center 203 of the roller.

[0045] In some embodiments, the water removal mechanism 4 includes a vaporization mechanism 42, which is used to blow air onto the surface of the middle part 203 of the cardboard support roller, so that the water adhering to the surface of the middle part 203 of the roller is rapidly vaporized to remove the surface water of the middle part 203 of the roller.

[0046] On the one hand, it can prevent the water adhering to the surface of the cardboard support roller 2 from being rotated and brought into contact with the hot cardboard 100 above. On the other hand, the water vaporizes and absorbs heat, which allows the cardboard support roller 2 to be cooled down quickly, which is more conducive to cooling the hot cardboard 100.

[0047] In some embodiments, the vaporization mechanism 42 includes a nozzle 421 for communicating with an external air source. The nozzle 421 is mounted on the mounting bracket 1 and blows air onto the surface of the roller center 203.

[0048] Preferably, multiple air nozzles 421 are provided, and the multiple air nozzles are spaced apart along the axial direction of the cardboard support roller 2.

[0049] In some embodiments, the water removal mechanism 4 may include both the aforementioned scraping mechanism 41 and vaporization mechanism 42.

[0050] like Figure 1 As shown, preferably, in the forward rotation direction of the cardboard support roller 2, the middle part 203 of the roller is first treated by the scraping mechanism 41 and then treated by the surface blowing mechanism 42.

[0051] In some embodiments, the rapid hot paperboard cooling device further includes a drive mechanism (not shown) for driving the paperboard support roller 2 to rotate.

[0052] In some embodiments, the drive mechanism includes a drive motor mounted on a mounting frame, which drives the cardboard support roller 2 to rotate.

[0053] In some embodiments, this rapid hot paperboard cooling device further includes a top pressure roller 5 rotatably connected to the mounting frame 1. The top pressure roller 5 is located above the paperboard support roller 2, and cooperates with the paperboard support roller 2 to press the hot paperboard 100. When the drive mechanism drives the paperboard support roller 2, the paperboard support roller 2 can correspondingly pull the hot paperboard 100 to convey it to the next process. The paperboard support roller 2 can constitute both cooling and traction conveying of the hot paperboard 100, thus improving its practicality.

[0054] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
