Description

Technical Field

[0001] This application relates to the field of preheating roller technology, specifically an energy-saving preheating roller. Background Technology

[0002] Before applying adhesive to the paper, the paper is preheated using a preheating roller to help the adhesive adhere better to the paper.

[0003] For example, Chinese Patent (Announcement No.: CN 212093063 U) discloses a preheating roller for a coating machine. Its structure includes a heating device and several parallel, staggered preheating rollers. The heating device controls the heating temperature of the preheating rollers, which together form a uniquely shaped film passage. The two ends of the film passage face the coating machine and the oven, respectively. The processed film contacts the circumferential surface of the preheating roller through the film passage. The preheating roller rotates as the processed film moves. This design allows for simultaneous film transfer via the preheating roller and operation of the processed film via the heating device, thereby reducing the temperature difference between the processed film and the oven. This reduces surface wrinkles caused by thermal shrinkage. Furthermore, preheating via the preheating roller increases the film surface temperature, improving the silicone oil reaction and curing, enhancing the product's residual adhesion, and reducing silicone transfer.

[0004] The preheating rollers used in coating machines have certain shortcomings. While the preheating roller is used to transfer the processed film, a heating device can be used to operate the processed film, thereby reducing the temperature difference between the processed film and the oven, and thus reducing surface wrinkles caused by thermal shrinkage. However, heating the preheating roller requires more energy because the inside of the preheating roller is hollow, which is not only wasteful of energy but also time-consuming and labor-intensive. Therefore, an energy-saving preheating roller is proposed to solve the above problems. Utility Model Content

[0018] By adopting the above technical solution, a sandwich is formed by the cooperation of the cylinder and the roller. The heated air can make the roller heat better and facilitate the heating of the paper.

[0019] Furthermore, the rotating mechanism includes a housing fixed to the left side of the right vertical plate, a motor fixed to the left side of the inner cavity of the housing, a rotating rod fixed to the output shaft of the motor, and a transmission assembly provided on the outer surface of the rotating rod.

[0020] The above technical solution is used to rotate the roller shaft, which facilitates the heating of the paper by the roller shaft.

[0021] Furthermore, the transmission assembly includes a first sprocket fixed to the outer surface of the rotating rod and a second sprocket fixed to the outer surface of the right connecting pipe, with a chain drivingly connected to the outer surfaces of the first sprocket and the second sprocket.

A rotating mechanism 4 is provided on the left side of the right vertical plate 3 for rotating the roller shaft 6, which facilitates the application of glue after the paper is heated.

[0032] The inner wall of the roller 6 is fixed with multiple connecting rods, and a cylinder is fixed on the side of the multiple connecting rods away from the roller 6. The cylinder cooperates with the roller 6 to form a sandwich, and the heated air can make the roller 6 heat up better and facilitate the heating of the paper.

[0033] Please see Figure 2 In order to heat the roller 6, the heating mechanism 2 in this embodiment includes a box 201 fixed to the upper surface of the base plate 1, a first fan 205 and a second fan 209. The inner wall of the box 201 is fixed with multiple partitions 202 and heating rods 203. The heating rods 203 heat the air, and the partitions 202 make the air follow an S-shaped path to make the air heated evenly. The input end of the first fan 205 is fixed with a first air pipe 204, and the output end of the first fan 205 is fixed with a second air pipe 206.

The heating mechanism 2 also includes a rotary joint 207 fixed to the opposite side of the two connecting pipes 5.

[0034] The left side of the first air pipe 204 is fixed to the right side of the box 201, and the right side of the fourth air pipe 210 is fixed to the left side of the box 201. The heated air in the box 201 enters the second air pipe 206 through the first air pipe 204, and the air inside the third air pipe 208 enters the box 201 through the fourth air pipe 210. The second air pipe 206 and the third air pipe 208 are both U-shaped. The opposite sides of the second air pipe 206 and the third air pipe 208 are respectively fixed to the opposite sides of the two rotary joints 207. The rotary joints 207 prevent the second air pipe 206 and the third air pipe 208 from rotating with the connecting pipe 5.

[0035] In addition, a through hole is provided on the upper surface of the box 201, and a dustproof mesh is fixed inside the through hole to prevent dust from entering the box 201. A first air hole is provided on the right side of the upper surface of the upper partition 202, a second air hole is provided on the left side of the upper surface of the middle partition 202, and a third air hole is provided on the right side of the upper surface of the lower partition 202. The air is made to follow an S-shaped path through the partition 202 to make the air heated evenly.

[0036] In this embodiment, the heating mechanism 2 has a first fan 205 that draws air into the housing 201. The air is heated by the heating rod 203 and heated evenly by the partition 202 before entering the first air pipe 204. It then enters the roller 6 through the second air pipe 206, the rotary joint 207, and the right-end connecting pipe 5 to heat the roller 6. After use, the air enters the housing 201 through the left-end connecting pipe 5, the left-end rotary joint 207, the third air pipe 208, and the fourth air pipe 210, allowing for recycling.

[0037] Please see Figure 3 In order to rotate the roller 6, the rotating mechanism 4 in this embodiment includes a housing 401 fixed to the left side of the right vertical plate 3. A motor 402 is fixed to the left side of the inner cavity of the housing 401. A rotating rod 403 is fixed to the output shaft of the motor 402. A transmission assembly 404 is provided on the outer surface of the rotating rod 403. The rotating rod 403 drives the right end connecting pipe 5 to rotate through the transmission assembly 404.

[0038] The transmission assembly 404 includes a first sprocket fixed to the outer surface of the rotating rod 403 and a second sprocket fixed to the outer surface of the right connecting pipe 5. The outer surfaces of the first sprocket and the second sprocket are connected by a chain. The rotating rod 403 drives the right connecting pipe 5 to rotate through the transmission assembly 404.

[0039] In addition, the housing 401 is a cuboid with a hollow interior and a missing right end. The right side of the rotating rod 403 is rotatably connected to the left side of the right vertical plate 3 through a bearing seat, which increases the stability of the rotating rod 403 when it rotates.

[0040] In this embodiment, the rotating mechanism 4 is driven by the motor 402 to rotate the rotating rod 403. The rotating rod 403 drives the right end connecting pipe 5, the roller 6 and the left end connecting pipe 5 to rotate together through the transmission assembly 404, which facilitates the preheating of the paper and helps the adhesive to better adhere to the paper.

[0041] The working principle of the above embodiments is as follows:

[0042] (1) When the roller 6 needs to be heated, turn on the first fan 205 and the second fan 209. The first fan 205 draws air into the housing 201 through the through hole. The air will be heated by the heating rod 203. At the same time, the air will enter the first air pipe 204 through the first air hole, the second air hole and the third air hole, and then enter the second air pipe 206 from the first air pipe 204. The heated air enters the roller 6 from the second air pipe 206 through the right end rotary joint 207 and the right end connecting pipe 5 to heat the roller 6. The used air will enter the third air pipe 208 through the left end connecting pipe 5 and the left end rotary joint 207, and then be sent to the housing 201 through the fourth air pipe 210 by the second fan 209. It can be recycled.

[0043] (2) When it is necessary to rotate the roller 6, turn on the motor 402. The motor 402 drives the rotating rod 403 and the first sprocket to rotate together. The first sprocket drives the second sprocket and the right end connecting pipe 5 to rotate together through the chain. When the right end connecting pipe 5 rotates, it will drive the roller 6 and the left end connecting pipe 5 to rotate together, which is convenient for preheating the paper and helps the adhesive to adhere better to the paper.
