Description

Technical Field

[0001] This utility model relates to the technical field of air heating devices for the paper industry, specifically a high thermal efficiency air tumbling device for the paper industry. Background Technology

[0002] The paper industry is an important basic raw material industry closely related to national economic and social development. The paper industry has a huge market size and shows a steady growth trend. Asia, especially China, has become the world's largest paper production and consumption market. China's paper industry is among the world's leaders in terms of scale, technology and market influence. The main drivers of market growth include economic development, population growth, consumption upgrading and technological progress.

[0003] In the papermaking industry, heating and drying is a crucial step that directly affects paper quality and production efficiency. Heating and drying equipment is required during the heating and drying process of paperboard. Currently available heating and drying equipment can use hot air to heat and dry paperboard.

[0004] However, existing heating and drying devices cannot adjust the direction of hot air blowing, resulting in inconsistent drying speeds between the upper and lower layers of cardboard. This makes it easy for some cardboard to be over-dried and others to be under-dried, which seriously affects the heating and drying quality of the cardboard, resulting in more defective products and economic losses. Therefore, a high thermal efficiency air-turning device for the paper industry is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a high-efficiency air-turning device for the paper industry. This solves the problem that existing heating and drying devices cannot adjust the direction of hot air blowing, resulting in inconsistent drying speeds between the upper and lower layers of cardboard. This causes the cardboard to be over-dried in some areas and under-dried in others, which seriously affects the heating and drying quality of the cardboard, resulting in more defective products and economic losses.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high thermal efficiency air-turning device for the paper industry, comprising a box and a tray, wherein a heating and turning mechanism is provided inside the box;

[0007] The heating and turning mechanism includes a rotating shaft rotatably connected inside the box body. A heating and drying chamber is fixedly installed on the outside of the rotating shaft. A fan unit and an air heating pipe are fixedly connected inside the heating and drying chamber. First filter screens are fixedly connected to the top and bottom of the heating and drying chamber. A mounting bracket is fixedly connected to the left side of the box body. A drive motor is fixedly connected to the outside of the mounting bracket. A drive gear is fixedly connected to the output shaft of the drive motor. A driven gear is fixedly connected to the outer surface of the rotating shaft. An air inlet and outlet are provided on the right side of the box body. A cover is fixedly connected to the right side of the box body. A second filter screen is fixedly connected to the outside of the cover.

[0008] Furthermore, the left end of the rotating shaft passes through the housing and extends to the inside of the mounting bracket, and the end face of the rotating shaft is rotatably connected to the inside of the mounting bracket.

[0009] Furthermore, the driving gear meshes with the driven gear, and the outer diameter of the driving gear is smaller than that of the driven gear.

[0010] Furthermore, a positioning guide rail is fixedly connected inside the box, and the positioning guide rail is slidably connected to the tray.

[0011] Furthermore, a sealed door is hinged to the front of the enclosure, and a temperature sensor is installed on the top of the enclosure.

[0012] Furthermore, a temperature display and an alarm are fixedly connected to the outer surface of the sealed door.

[0013] Furthermore, a support base is fixedly connected to the bottom of the box, and a rubber pad is adhered to the bottom of the support base.

[0014] Compared with the prior art, this utility model provides a high thermal efficiency air-turning device for the paper industry, which has the following beneficial effects:

[0015] This high-efficiency air-turning device for the paper industry, through a heating and turning mechanism, converts electrical energy into heat energy through air heating tubes to heat the air. The fan unit blows the heated air in a single direction to heat and dry the cardboard inside the tray. By starting the drive motor and periodically controlling the forward and reverse rotation frequency of its output shaft, the meshing transmission between the drive gear and driven gear drives the rotating shaft to rotate in the opposite direction to the drive motor's output shaft. This clockwise or counterclockwise rotation of the shaft causes the heating and drying chamber to periodically rotate 180 degrees, thereby periodically adjusting the direction of the hot air blown by the fan unit to dry the interior of the chamber. The lower two layers are dried with uniform hot air, ensuring that the drying speed of the two layers of cardboard is not significantly different. In addition, the first and second filters can block dust and debris. At the same time, their relatively fine mesh can reduce the speed at which hot air escapes, ensuring heat retention and thus improving heating and drying efficiency. Compared with existing heating and drying devices, this method achieves the effect of flipping to adjust the direction of hot air blowing, ensuring that the drying speed of the two layers of cardboard is not significantly different. This reduces the occurrence of over-drying and under-drying of some cardboard, effectively improving the heating and drying quality of the cardboard, reducing the number of defective products, and minimizing economic losses.

[0021] 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.

[0022] Example 1:

[0023] Please see Figures 1 to 3 A high thermal efficiency paper industry air flipping device in this embodiment includes a box 1 and a tray 2, and a heating flipping mechanism is provided inside the box 1.

[0024] The heating and turning mechanism includes a rotating shaft 3 rotatably connected inside the housing 1. A heating and drying chamber 4 is fixedly installed outside the rotating shaft 3. A fan unit 5 and an air heating pipe 6 are fixedly connected inside the heating and drying chamber 4. A first filter screen 7 is fixedly connected to the top and bottom of the heating and drying chamber 4. A mounting bracket 8 is fixedly connected to the left side of the housing 1. A drive motor 9 is fixedly connected to the outside of the mounting bracket 8. A drive gear 10 is fixedly connected to the output shaft of the drive motor 9. A driven gear 11 is fixedly connected to the outer surface of the rotating shaft 3. An air inlet and outlet 12 is opened on the right side of the housing 1. A cover 13 is fixedly connected to the right side of the housing 1. A second filter screen 14 is fixedly connected to the outside of the cover 13. Through the heating and turning mechanism, when in use, the air heating pipe 6 can convert electrical energy into heat energy to heat the air. The fan unit 5 can blow the hot air heated by the air heating pipe 6 in one direction to heat and dry the cardboard inside the tray 2.

[0025] By starting the drive motor 9 and controlling the forward and reverse rotation frequency of its output shaft at regular intervals, the meshing transmission between the drive gear 10 and the driven gear 11 drives the rotating shaft 3 to rotate in the opposite direction to the output shaft of the drive motor 9. This causes the rotating shaft 3, rotating clockwise or counterclockwise, to rotate the heating and drying chamber 4 at regular intervals by 180 degrees. This, in turn, adjusts the direction of the hot air blown out by the fan unit 5 at regular intervals to uniformly dry the upper and lower layers of space inside the chamber 1 with hot air. Ultimately, this ensures that the drying speed of the two layers of cardboard is not significantly different.

[0026] In addition, the first filter 7 and the second filter 14 can block dust and debris. At the same time, their relatively fine mesh can reduce the speed at which hot air escapes outward, ensuring heat retention and thus improving heating and drying efficiency.

[0027] It should be noted that the left end of the rotating shaft 3 passes through the housing 1 and extends to the inner side of the mounting bracket 8. The end face of the rotating shaft 3 is rotatably connected to the inner side of the mounting bracket 8. The driving gear 10 and the driven gear 11 mesh and drive each other. The outer diameter of the driving gear 10 is smaller than the outer diameter of the driven gear 11.

[0028] The box 1 is fixedly connected to a positioning guide rail 15, which is slidably connected to the pallet 2. By setting the positioning guide rail 15, it is easy for staff to quickly push the pallet 2 containing cardboard into its inner side for simple positioning.

[0029] Example 2:

[0030] Please see Figure 1 and Figure 4 Based on Embodiment 1, a sealing door 16 is hinged to the front of the box 1, a temperature sensor 17 is installed on the top of the box 1, and a temperature display 18 and an alarm 19 are fixedly connected to the outer surface of the sealing door 16. By setting the temperature sensor 17, the temperature display 18 and the alarm 19, the effect of real-time temperature detection and overheat alarm is achieved.

[0031] In addition, a support base 20 is fixedly connected to the bottom of the box 1, and a rubber pad 21 is glued to the bottom of the support base 20. By setting the support base 20 and the rubber pad 21, the box 1 is stably supported.

[0032] The working principle of the above embodiments is as follows:

[0033] In use, the operator first needs to open the sealing door 16, then quickly push the trays 2 containing cardboard one by one into the positioning guide rails 15 for simple positioning, so that the cardboard is evenly distributed in the upper and lower spaces of the box 1. Then, the sealing door 16 is closed, and the air heating pipe 6 and fan unit 5 are started. The air heating pipe 6 converts electrical energy into heat energy to heat the air, and the fan unit 5 blows the heated air from the air heating pipe 6 in a single direction to heat and dry the cardboard inside the trays 2. During heating and drying, the drive motor 9 is started and its output shaft's forward and reverse rotation frequency is controlled periodically. The meshing transmission between the driving gear 10 and the driven gear 11 drives the rotating shaft 3 to rotate in the opposite direction to the output shaft of the drive motor 9. This causes the rotating shaft 3, rotating clockwise or counterclockwise, to rotate the heating and drying chamber 4 180 degrees at regular intervals. This, in turn, adjusts the direction of the hot air blown out by the fan unit 5 at regular intervals to ensure uniform hot air drying of the upper and lower spaces inside the chamber 1. Ultimately, this ensures that the drying speed of the two layers of cardboard is not significantly different. In addition, the first filter screen 7 and the second filter screen 14 can block dust and debris. At the same time, their relatively fine mesh can reduce the speed at which hot air escapes outward, ensuring heat retention and thus improving the heating and drying efficiency.

[0034] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
