Description

Technical Field

[0001] This utility model belongs to the field of paper processing technology, specifically, it relates to a soft calendering device for decorative paper. Background Technology

[0002] The printing base paper needs further processing. The surface calendering device is a calender, which is used to improve the gloss of the paper surface. After the paper is coated with printed materials, the varnish layer is not smooth enough. The calender can improve the smoothness and gloss of the paper surface. The calender is mainly composed of a printing material conveying mechanism, mechanical transmission, electrical control system and other parts.

[0003] Chinese utility model patent CN216107819U discloses an improved digital printing base paper surface calendering device, including a calendering mechanism, a support platform, and a drying mechanism. The drying mechanism includes a blower box and at least two exhaust fans. The air outlet of each exhaust fan is connected to an air supply duct. The end of the air supply duct away from the exhaust fan is connected to the blower box. The air inlet of each exhaust fan is equipped with a filter assembly. The filter assembly includes a cylinder, and an air purification screen is installed inside the cylinder. Activated carbon filter elements are provided on both sides of the air purification screen. The exhaust fans, air supply duct, and blower box can dry the base paper, accelerate the curing speed of the coating, and thus improve the calendering efficiency of the printing base paper. The airflow can be purified by the metal baffle, activated carbon filter elements, and air purification screen, thereby effectively preventing dust and other impurities in the cold air from adhering to the coating and improving the quality of the printing base paper.

[0004] Although the aforementioned existing technology can cure the coating by air drying, the blowing method can easily cause the coating on the surface to be blown away before curing, resulting in the coating not being uniform on the surface of the base paper and affecting the finished product of the base paper.

Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] To address the problem mentioned in the background art that the blowing method can easily cause the surface coating to be blown away before curing, resulting in uneven coating on the surface of the base paper and affecting the finished product of the base paper, this utility model adopts the following technical solution.

[0007] A decorative base paper soft calendering device includes a mounting base plate, a second bracket detachably connected to one side of the upper end of the mounting base plate, a calendering assembly mounted on the second bracket, a first bracket detachably connected to the other side of the mounting base plate, a winding assembly mounted on the first bracket, a drying cylinder with upper and lower opposite sides arranged at the center of the upper end of the mounting base plate, a first support vertical plate arranged at one end of the drying cylinder and a second support vertical plate arranged at the other end, heating rollers mounted on the inner walls of the two opposite sides of the drying cylinder, and graphene sprayed on the surface of the drying cylinder.

[0008] Preferably, the drying cylinder is provided through at both ends, and a first sealing plate is rotatably connected to one end of the drying cylinder.

The heat insulation semi-arc plate is detachably connected to the first sealing plate, and a heating roller located outside the heat insulation semi-arc plate is fixedly connected to the first sealing plate.

[0009] Preferably, a rotating assembly is installed on the drying cylinder, which causes the drying cylinders on both sides to rotate.

[0010] Preferably, a heat dissipation component is installed inside the drying cylinder, which dissipates heat from the outer wall of the drying cylinder away from the raw paper.

[0011] Preferably, a third bracket is provided on both sides of the drying cylinder at the upper end of the mounting base plate, and a rotating roller is rotatably connected to the third bracket. The raw paper is S-shaped and fits against the outer wall of the rotating roller on both sides.

[0012] Preferably, the rotating assembly includes a drive sprocket, a meshing chain, a connecting shaft, and a drive motor.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. The heating rollers on both sides generate heat on the outer walls of the opposite sides of the drying cylinder, thereby drying the paper in the middle. Graphene can increase the heat radiation effect.

[0017] 2. The drive motor in the rotating assembly drives the drive sprocket and drying cylinder on one side to rotate. The meshing chain causes the drying cylinder and drive sprocket on the other side to rotate, thus enabling the drying cylinder to rotate.

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0031] like Figure 1 The diagram shows a preferred embodiment of a decorative base paper soft calendering device of this utility model. The device includes a mounting base plate 100, a second support 104 detachably connected to one side of the upper end of the mounting base plate 100, a calendering assembly 101 mounted on the second support 104, and a first support 103 detachably connected to the other side of the mounting base plate 100, a winding assembly 102 mounted on the first support 103. A drying cylinder 200 with opposing sides is located at the center of the upper end of the mounting base plate 100. In this embodiment, after the base paper is calendered by the calendering assembly 101, it is wound up by the winding assembly 102 between the two drying cylinders 200. The opposing outer walls of the two drying cylinders 200 heat up and dry the coating on the base paper, thereby preventing the coating on the base paper from becoming uneven and preventing dust from falling onto the surface of the base paper.

[0032] like Figure 2 As shown, this is a schematic diagram of the drying cylinder structure in this embodiment. One end of the drying cylinder 200 is provided with a first supporting vertical plate 207 and the other end is provided with a second supporting vertical plate 214. Heating rollers 205 are installed on the inner walls of the drying cylinders 200 on both sides. Graphene is sprayed on the surface of the drying cylinder 200. In this embodiment, the heating of the heating rollers 205 on both sides generates heat on the outer walls of the opposite sides of the drying cylinders 200, thereby drying the paper in the middle. Graphene can increase the heat radiation effect.

[0033] like Figure 2-3As shown, this is a schematic diagram of the rotating component structure in this embodiment. The drying cylinder 200 extends through both ends. A second sealing plate 206 is fixedly connected to one end of the drying cylinder 200. A drive sprocket 209 is fixedly connected to the second sealing plate 206. A connecting shaft 213, rotatably connected to the first support vertical plate 207, is fixedly connected to the drive sprocket 209. Engaging chains 210 are sleeved on the outer walls of the drive sprockets 209 on both sides. A drive motor 211 is detachably connected to the outer wall of the first support vertical plate 207. The rotating end of the drive motor 211 is connected to the connecting shaft 213 on one side. A first sealing plate 201 is rotatably connected to the other end of the drying cylinder 200. The first sealing plate 201 and the second support vertical plate 207... The outer wall of the vertical plate 214 is detachably connected, the heat insulation semi-arc plate 204 is detachably connected to the first sealing plate 201, and a heating roller 205 located outside the heat insulation semi-arc plate 204 is fixedly connected to the first sealing plate 201. In this embodiment, the drive motor 211 drives one side drive sprocket 209 and drying cylinder 200 to rotate, and the meshing chain 210 causes the other side drying cylinder 200 and drive sprocket 209 to rotate, thereby enabling the drying cylinder 200 to rotate. The setting of the first sealing plate 201 keeps the heating rollers 205 on both sides stationary, thereby preventing the continuous heating of the heating rollers 205 from causing the temperature of the drying cylinder 200 to be too high and damaging the raw paper.

[0034] It is worth noting that the aforementioned drive sprocket 209, meshing chain 210, connecting shaft 213, and drive motor 211 are rotating components in this embodiment. Rotating components include, but are not limited to, drive sprocket 209, meshing chain 210, connecting shaft 213, and drive motor 211. Any component that can make the drying cylinder 200 rotate can be used in this embodiment.

[0035] like Figure 2 As shown, this is the heat dissipation component in this embodiment. The first sealing plate 201 is provided with multiple air inlets 202, and the second sealing plate 206 is provided with multiple air outlets 212. A cooling fan 203 is detachably connected to the first sealing plate 201. In this embodiment, the external air is drawn into the drying cylinder 200 by the rotation of the cooling fan 203 and sprayed out from the air outlets 212, thereby cooling the part of the drying cylinder 200 that is far away from the original paper. The heat insulation semi-arc plate 204 can prevent the temperature of the outer wall near the original paper from dropping too much, which would prevent drying.

[0036] It is worth noting that the cooling fan 203, air inlet 202 and first sealing plate 201 mentioned above are heat dissipation components in this embodiment. The heat dissipation components include, but are not limited to, the cooling fan 203, air inlet 202 and first sealing plate 201. Any component that can cool down the part of the drying cylinder 200 away from the raw paper can be applied to this embodiment.

[0037] like Figure 2 As shown, in order to prevent the exhaust hot air from causing the drive motor 211 to overheat, in this embodiment, hot air guide plates 208 are fixedly connected to both sides of the outer wall of the first support vertical plate 207 near the drive motor 211. The hot air guide plates 208 can guide the hot air to both sides, preventing the hot air from contacting the drive motor 211 and causing it to overheat and malfunction.

[0038] like Figure 4 As shown, this is a schematic diagram of the supporting component structure in this embodiment. The upper end of the mounting base plate 100 is provided with a third bracket 300 on both sides of the drying cylinder 200. A rotating roller 301 is rotatably connected to the third bracket 300. The raw paper is S-shaped and fits against the outer wall of the rotating roller 301 on both sides. In this embodiment, the setting of the rotating roller 301 can avoid the raw paper from contacting the drying cylinder 200 and causing damage to the raw paper, and can also make the heating of both sides of the raw paper uniform.
