Description

Technical Field

[0001] This application relates to the field of drying equipment technology, and more specifically, it relates to a drying apparatus for paper product processing. Background Technology

[0002] In the paper processing industry, kraft paper is widely used in the packaging industry due to its high strength and wear resistance. However, traditional kraft paper drying equipment often adopts a heating structure with a single heat source, which can easily cause uneven heating on both sides of the kraft paper. This can lead to local over-drying and embrittlement, while the other side will experience a decrease in strength due to residual moisture, thus affecting the drying quality of the kraft paper and its subsequent normal use. Utility Model Content

[0003] To address the shortcomings of the existing technology, the purpose of this application is to provide a drying device for paper product processing, including a drying box. The drying box is equipped with a traction mechanism for loading and unloading kraft paper placed inside it. Multiple mounting frames are staggered on both sides of the kraft paper, and multiple electric heating tubes for increasing the temperature inside the drying box are equidistantly arranged on the mounting frames. An air inlet is opened on one side of the drying box to deliver airflow into it. Airflow is delivered into the drying box through the air inlet, thereby dissipating the heat accumulated inside the drying box and wrapping the kraft paper, thus achieving simultaneous drying of both sides of the kraft paper.

[0004] Preferably, the drying chamber is further provided with an impeller to guide the airflow entering it, and the impeller is located above the air inlet.

[0005] Preferably, the back of the drying chamber is provided with a drive motor that drives the impeller to rotate inside it, and the drive motor is connected to the impeller drive motor.

[0006] Preferably, the traction mechanism includes an active roller rotatably disposed on one side inside the drying chamber, a driven roller that cooperates with the active roller to traction and feed the kraft paper, and a feeding roller rotatably disposed on the other side inside the drying chamber to traction and unload the kraft paper.

[0007] Preferably, the back of the drying chamber is also provided with a dual-axis motor that drives the active roller to rotate inside it. One end of the dual-axis motor is connected to the active roller, and the other end of the dual-axis motor is coaxially provided with an active synchronous pulley. One end of the feeding roller is coaxially provided with a driven synchronous pulley. A synchronous belt is provided between the active synchronous pulley and the driven synchronous pulley. The dual-axis motor drives the active roller and the feeding roller to rotate simultaneously inside the drying chamber through the transmission cooperation between the active synchronous pulley, the driven synchronous pulley and the synchronous belt.

[0008] Preferably, the drying chamber has a feed inlet for feeding kraft paper on the other side, and a discharge outlet for unloading kraft paper on the side of the drying chamber with the air inlet, and the discharge outlet is located above the air inlet.

[0009] Preferably, the top of the drying box has multiple air holes at equal intervals for the water vapor inside to be discharged, and the sides of the air holes are provided with dust baffles to prevent external dust and impurities from entering the drying box.

[0010] In summary, the beneficial effects of this application are as follows:

[0011] By using staggered heating tubes, heat is applied to both sides of the kraft paper. Combined with warm air entering from the air inlet, the heat is distributed throughout the drying chamber, ensuring that the moisture inside the kraft paper is evaporated evenly. This avoids embrittlement and residual moisture caused by overheating on one side. It effectively solves the technical problem that traditional kraft paper drying equipment often uses a heating structure with a single heat source, which easily leads to uneven heating on both sides of the kraft paper, resulting in local over-drying and embrittlement, while the other side suffers from reduced strength due to residual moisture, thus affecting the drying quality and subsequent normal use of the kraft paper.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0020] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0021] A drying apparatus for paper product processing, see [link to apparatus]. Figures 1 to 4 The system includes a drying chamber 1, which is equipped with a traction mechanism 2 for loading and unloading kraft paper placed inside it. Multiple mounting brackets 3 are staggered on both sides of the kraft paper, and multiple electric heating tubes 4 are equidistantly arranged on the mounting brackets 3 to increase the internal temperature of the drying chamber 1. An air inlet 5 is opened on one side of the drying chamber 1 to deliver air into it. Air is delivered into the drying chamber 1 through the air inlet 5, thereby dissipating the heat collected inside the drying chamber 1 and wrapping the kraft paper, thus achieving simultaneous drying of both sides of the kraft paper. In this embodiment, the air inlet 5 is connected to an external warm air blower pipeline, and the warm air generated by the external warm air blower is delivered into the drying chamber 1 through the air inlet 5.

[0022] Therefore, when kraft paper needs to be dried, simply place the kraft paper to be dried inside the traction mechanism 2, and then control the heating element 4 through the external control system to generate heat, which heats the air around the heating element 4. During the operation of the heating element 4, an external heater can be activated. The warm air generated by the external heater will be simultaneously delivered into the drying chamber 1. After entering the drying chamber 1, the warm air will drive the airflow inside the drying chamber 1, thereby diffusing the heat around the heating element 4 and wrapping the kraft paper inside the drying chamber 1, thus achieving the desired drying effect. The kraft paper is dried simultaneously from both sides. Therefore, the staggered heating tubes 4 ensure that both sides of the kraft paper have a heat source. Combined with the warm air input from the air inlet 5, the heat from the heat source is transported to all parts of the drying chamber 1. This ensures that the moisture inside the kraft paper is evaporated evenly, avoiding embrittlement and moisture residue caused by overheating on one side. This effectively solves the technical problem that traditional kraft paper drying equipment often uses a heating structure with a single heat source on one side, which easily causes uneven heating on both sides of the kraft paper, resulting in local over-drying and embrittlement, while the other side suffers from reduced strength due to moisture residue, thus affecting the drying quality of the kraft paper and its subsequent normal use.

[0023] The drying chamber 1 is also equipped with an impeller 6 that guides the airflow entering it, and the impeller 6 is located above the air inlet 5. The back of the drying chamber 1 is equipped with a drive motor 7 that drives the impeller 6 to rotate inside it, and the drive motor 7 is connected to the impeller 6. In this embodiment, the drive motor 7 drives the impeller 6 to rotate inside the drying chamber 1, thereby guiding the warm air entering the drying chamber 1 and driving the airflow inside the drying chamber 1 to move, thereby realizing the diffusion of the heat generated by the electric heating tube 4. The rotation of the impeller 6 forms a forced airflow circulation, which effectively breaks the laminar distribution of the hot air inside the drying chamber 1, so that the heat generated by the electric heating tube 4 and the input warm air can be diffused to the entire cavity, reducing the accumulation of heat and effectively improving the practicality of this embodiment.

[0024] The traction mechanism 2 includes a drive roller 201 rotatably disposed on one side inside the drying chamber 1, a driven roller 202 cooperating with the drive roller 201 to traction and feed the kraft paper, and a feeding roller 203 rotatably disposed on the other side inside the drying chamber 1 to traction and unload the kraft paper. A dual-axis motor 204 is also disposed on the back of the drying chamber 1 to drive the drive roller 201 to rotate inside it. One end of the dual-axis motor 204 is connected to the drive roller 201, and the other end of the dual-axis motor 204 is coaxially disposed with a drive synchronous pulley 205. One end of the feeding roller 203 is coaxially disposed with a driven synchronous pulley 206. A synchronous belt 207 is connected between the drive synchronous pulley and the driven synchronous pulley. The dual-axis motor 204 drives the drive roller 201 and the feeding roller 203 simultaneously inside the drying chamber 1 through the transmission cooperation between the drive synchronous pulley 205, the driven synchronous pulley 206, and the synchronous belt 207. The drying chamber 1 is rotated; a feed inlet 8 for feeding kraft paper is provided on the other side, and an outlet 9 for unloading kraft paper is provided on the other side of the drying chamber 1 with an air inlet 5. The outlet 9 is located above the air inlet 5. In this embodiment, one end of the kraft paper to be dried enters the interior of the drying chamber 1 through the feed inlet 8, then passes between the drive roller 201 and the driven roller 202 and covers the top of the feeding roller 203. Finally, it is discharged from the top of the feeding roller 203 through the outlet 9. In this embodiment, by vertically staggering the feed inlet 8 and the outlet 9, the kraft paper can form an S-shaped path in the drying chamber 1, thereby effectively extending the drying time and avoiding wrinkles and deformation of the kraft paper caused by sharp bends. In addition, in order to improve the efficiency of kraft paper loading and unloading, the outer surfaces of the drive roller 201, the driven roller 202 and the feeding roller 203 are respectively surrounded by anti-slip textures 10.

[0025] The top of the drying chamber 1 has multiple vents 11 evenly spaced to allow internal moisture to escape. Dust baffles 12 are installed on the sides of the vents 11 to prevent external dust and impurities from entering the drying chamber 1. In this embodiment, the dust baffles 12 are obliquely positioned on the sides of the vents 11, and together with the equidistantly arranged vents 11, they form a dynamic dehumidification and protection system. Driven by the impeller 6, a directional airflow channel is formed, thereby expelling the moisture generated during the drying process of the kraft paper from the vents 11. Simultaneously, the dust baffles 12 effectively prevent backflow of dust through negative pressure adsorption, avoiding the entry of external dust and other impurities into the drying chamber 1 and contaminating the kraft paper. Furthermore, the drying chamber 1 is equipped with multiple temperature sensors 13 that monitor its internal temperature. These temperature sensors 13 are located on the inner walls of the drying chamber 1, and are electrically connected to an external control system. By installing the temperature sensors 13, this embodiment can monitor the working temperature inside the drying chamber 1 in real time and feed the monitored signals back to the external control system, thereby achieving… The current closed-loop control of "temperature monitoring - signal feedback - power adjustment" allows the control system to automatically adjust the input power of the heating element 4 when the temperature sensor 13 detects that the working temperature inside the drying chamber 1 deviates from the preset heat range according to the different drying effects required for the kraft paper. This avoids the kraft paper becoming brittle due to over-drying caused by temperature fluctuations or failing to achieve the required drying effect. Furthermore, the heat generated by the heating element 4, the temperature of the warm air output by the heater, and the loading and unloading speed are all related to the drying effect of the kraft paper. Therefore, the specific heat generated by the heating element 4, the specific temperature of the warm air output by the heater, and the specific loading and unloading speed need to be determined based on the actual drying effect of the kraft paper. Thus, in this embodiment, the temperature generated by the heating element 4 and the temperature of the warm air are not limited. Moreover, the heater, heating element 4, dual-axis motor 204, and temperature sensor 13 can all be manufactured using known technologies. The specific selection and configuration of the heater, heating element 4, dual-axis motor 204, and temperature sensor 13 are not innovative points of this utility model and can be implemented with reference to existing technologies. Therefore, they will not be elaborated upon.

[0026] The drying chamber 1 is hinged to a protective door 14 on its front side, and each side of the protective door 14 is flush with each side of the drying chamber 1. The back of the protective door 14 is surrounded by a sealing element (not shown in the figure) to fill the gap between it and the drying chamber 1. The protective door 14 is provided with a handle 15 on its front side, and by holding the handle 15, the protective door 14 can be moved to the side of the drying chamber 1, thereby opening or closing the protective door 14 from the drying chamber 1. The protective door 14 is also provided with a glass window 16 for observing the working conditions inside the drying chamber 1.

[0027] The above embodiments are merely explanations of this application and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
