Description

Technical Field

[0001] The present invention relates to the technical field of paper production supporting equipment, in particular to an intelligent temperature-controlled energy-saving office paper rapid drying and flattening device. Background Art

[0002] In the production of office paper, paper drying and flattening are key post-processing steps that directly affect the quality, flatness, and production efficiency of the paper. Traditional paper drying processes mostly use hot air drying or contact drying with drying cylinders, which suffer from high energy consumption, low thermal efficiency, and uneven drying. Especially during high-speed production, paper is prone to deformation and warping due to uneven heating, affecting the subsequent flattening effect. Existing flattening equipment mostly uses mechanical roller pressing, which lacks coordinated temperature control, making it difficult to effectively eliminate internal stress in the paper, resulting in insufficient flatness. It also cannot achieve heat recovery and utilization in the production process, resulting in energy waste.

[0003] Existing drying equipment attempts to use air flotation technology to assist in conveying paper. However, the airflow control accuracy is insufficient, making it difficult to ensure smooth paper conveyance in high-temperature environments. Furthermore, the flattening and drying processes are often performed independently, lacking a continuous, intelligent temperature control and coordination mechanism. This results in low production efficiency and high energy consumption. Furthermore, traditional equipment fails to effectively recycle the waste heat generated during the drying and flattening processes, further increasing production costs and the environmental burden.

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Example 1

[0035] See also Figure 1-Figure 3 , an intelligent temperature-controlled energy-saving office paper rapid drying and flattening equipment, including a drying component, a flattening component 2, and a heat recovery component arranged in sequence along the paper 6 transmission direction.

[0036] The drying component includes a heating device 11, an air suspension component 12, and an eddy current auxiliary component 13. The heating device 11 and the eddy current auxiliary component 13 are arranged above the paper 6 and are arranged toward one side of the paper 6. The eddy current auxiliary component 13 is evenly arranged between adjacent heating devices 11. The air suspension component 12 is arranged below the paper 6 and is used for smooth transportation and drying of the paper 6.

[0037] The flattening assembly 2 includes multiple groups of parallel arranged pressure rollers 21, assembly brackets 22, and hydraulic telescopic cylinders 23. The assembly brackets 22 include multiple groups arranged evenly. Each group of assembly brackets 22 is driven by the hydraulic telescopic cylinder 23. The pressure rollers 21 are rotatably installed on the assembly brackets 22, and the paper 6 is arranged in sequence around each group of pressure rollers 21.

[0038] The heat recovery component includes multiple groups of heat dissipation rollers 31 arranged in parallel. The paper 6 is arranged to pass around each group of heat dissipation rollers 31 in sequence. The pressure roller 21 and the heat dissipation roller 31 are both equipped with a heat exchange component 4. The heat exchange component 4 is used to realize the heating operation of the pressure roller 21 and the heat dissipation operation of the heat dissipation roller 31.

[0039] After the paper 6 has been processed through the previous production process, it enters the rapid drying and flattening equipment provided in this application. After the drying and flattening operations, it forms a qualified paper 6 roll, and then enters the subsequent packaging and transportation processes.

[0040] When the paper 6 passes through the drying assembly, the air suspension assembly 12 installed below it can provide the paper 6 with upward buoyancy and forward driving force, thereby ensuring that the paper 6 is smoothly transported at the drying assembly position and smoothly transferred to the flattening assembly 2 on the downstream side. In addition, the air suspension assembly 12 can provide hot air to efficiently dry the paper 6.

[0041] The upper heating device 11 efficiently heats the paper 6, focusing the heat on the paper surface to warm the fibers and rapidly evaporate moisture. The vortex assist assembly 13 sprays a spiral stream of hot air onto the surface of the paper 6, extending the contact time between the heat and the paper, thereby improving heat exchange efficiency and entraining any moisture-absorbing air.

[0042] The flattening assembly 2 controls the hydraulic telescopic cylinder 23 to drive the assembly bracket 22 and the pressure roller 21 mounted thereon, adjusting the height and height of the assembly bracket 22. This provides a specific range of tension for the paper 6 being conveyed thereto. The continuous action of multiple sets of pressure rollers 21 on the paper 6 allows for rapid and efficient flattening. Simultaneously, the heat exchange assembly 4 within the pressure roller 21 heats the pressure roller 21, which in turn applies heat to the paper 6. This simultaneous heating of the paper 6 during the pressurization phase further flattens the surface of the paper 6, improving its flatness.

[0043] After being dried and flattened, the paper 6 is transferred to the heat dissipation roller 31 . The residual heat on the paper 6 can be absorbed by the heat exchange component 4 provided inside the heat dissipation roller 31 to achieve the purpose of heat energy recovery and thus achieve energy saving effect.

[0044] It should also be noted that the heat delivered by the heating device 11, air suspension assembly 12, and eddy current assist assembly 13 is detected by temperature sensors and feedback-regulated to keep the temperature of the paper 6 between 80°C and 150°C during the drying phase. The temperature of the pressure roller 21 in the flattening assembly 2 is also regulated by temperature sensors, keeping the temperature between 120°C and 200°C during the flattening phase.

[0045] Example 2

[0046] See also Figure 1-Figure 3 In order to ensure that the above-mentioned components can be stably assembled and operated, and to ensure efficient recovery and reuse of heat energy, the following technical solutions are provided.

[0047] It also includes an installation cover 5, in which a drying chamber 51, a flattening chamber 52, and a heat dissipation chamber 53 are arranged in sequence along the transmission direction of the paper 6. The drying component, the flattening component 2, and the heat recovery component are respectively assembled in the drying chamber 51, the flattening chamber 52, and the heat dissipation chamber 53.

[0048] The top of the drying chamber 51 is equipped with a heat collecting cover A511, the bottom side wall and top of the flattening chamber 52 are equipped with a heat supply cover 521 and a heat collecting cover B522 respectively, and the two sides of the heat dissipation chamber 53 are equipped with an air supply cover 531 and a heat collecting cover C532 respectively.

[0049] The arrangement of the drying chamber 51, the flattening chamber 52 and the heat dissipation chamber 53 can ensure the independence of the assembly and operation environment of the drying component, the flattening component 2 and the heat recovery component, and reduce the mutual interference of the components during operation.

[0050] The heat collection hood A511 in the drying chamber 51 extracts moisture and hot air from the drying chamber and recycles the heat energy. The heat supply hood 521 supplies hot air to the flattening chamber 52, thereby ensuring that the ambient temperature during the flattening of the paper 6 is maintained within the set temperature range. The heat collection hood B522 collects the hot air and residual heat after being heated by the paper 6. The air supply hood 531 in the heat dissipation chamber 53 is used to supply natural air to the heat dissipation chamber 53 to dissipate heat from the paper 6, while the heat collection hood C532 collects the heated air for recycling.

[0051] In order to ensure that the finished paper 6 can be stably transported between the drying component, the flattening component 2, and the heat recovery component, the following technical solution is provided.

[0052] The installation cover 5 is equipped with multiple sets of guide rollers 54. The upstream and downstream sides of the drying chamber 51, the flattening chamber 52 and the heat dissipation chamber 53 are all rotatably installed with guide rollers 54, and the paper 6 is arranged around each set of guide rollers 54.

[0053] The setting of the guide roller 54 can ensure that the paper 6 transmitted from the upstream side is introduced into the drying chamber 51, and is stably transmitted between the drying component, the flattening component 2, and the heat recovery component, and finally led out from the downstream side of the heat dissipation chamber 53 for rewinding.

[0054] Example 3

[0055] See also Figure 3-Figure 6 In order to ensure that the air suspension assembly 12 can be stably assembled in the drying chamber 51 and provide the paper 6 with uniform upward buoyancy and driving force for transmission to the downstream side, the following technical solutions are provided.

[0056] The air suspension component 12 includes multiple groups arranged evenly, and the air suspension component 12 includes an air supply pipe 121, an adjusting motor 122, and a matching combination of a worm gear 123 and a worm 124. The air supply pipe 121 is rotatably installed in the drying chamber 51. Multiple groups of air nozzles 125 are evenly connected to the air supply pipe 121. An air supply seat 126 and a worm gear 123 are respectively arranged at both ends of the air supply pipe 121. The worm gear 123 is coaxially fixed to the air supply pipe 121. The air supply seat 126 is fixedly installed to the outer wall of the drying chamber 51 and is rotationally connected to the air supply pipe 121. The adjusting motor 122 is fixedly installed to the outer wall of the drying chamber 51 and is dynamically connected to the worm 124.

[0057] Since the air supply pipe 121 remains rotatably installed, it is rotatably connected to the air supply pipe 121 through the fixed air supply seat 126. During the rotation of the air supply pipe 121, it can always ensure that the hot air is stably transmitted to the air supply pipe 121 through the air supply seat 126, and finally discharged outward through the air nozzle 125 provided thereon.

[0058] By adjusting the motor 122 to drive the worm 124 and worm gear 123, the air supply pipe 121 rotates, thereby forming a certain inclination angle between the air nozzle 125 and the paper 6. The vertical component of the high-speed airflow blown by the air nozzle 125 can steadily lift the paper 6, while the horizontal component can provide driving force for the paper 6 to be transported forward. By independently adjusting each group of air suspension components 12, it can be ensured that the paper 6 conveyed in the drying chamber 51 is always in a horizontal state.

[0059] The combination of the worm wheel 123 and the worm 124 has a one-way self-locking characteristic. When the adjustment motor 122 and the worm 124 are in a stationary state, the worm wheel 123 can be limited and locked to prevent the air supply pipe 121 from rotating ineffectively and interfering with the smooth transmission of the paper 6.

[0060] In order to ensure that the vortex auxiliary component 13 can effectively input the spiral airflow to act on the paper 6 and can effectively absorb the hot air containing moisture, the following technical solution is provided.

[0061] The vortex auxiliary component 13 includes a connecting seat 131, a jet cylinder 132, an air collecting sleeve 133, and an air supply ring pipe 134. The connecting seat 131 is fixedly installed in the drying chamber 51, and the jet cylinder 132 is fixedly installed to the bottom of the connecting seat 131. The air collecting sleeve 133 and the air supply ring pipe 134 are both arranged on the periphery of the jet cylinder 132. The air supply ring pipe 134 is connected to multiple groups of air supply branches 135 that are tangentially connected to the jet cylinder 132.

[0062] The connecting seat 131 can ensure that the jet cylinder 132 is stably installed thereon, and the high-pressure hot air provided by the air supply ring pipe 134 can be tangentially transported to the jet cylinder 132 through the air supply branch pipe 135, and then spirally transported downward under the limiting and guiding effects of the jet cylinder 132, thereby generating a spiral airflow acting on the upper surface of the paper 6, and the air collecting hood is arranged on the periphery of the jet cylinder 132, and cooperates with the jet cylinder 132 to form an air collecting chamber. After being connected to the vacuum pump, the air flow with moisture in the drying chamber 51 can be sucked into it and discharged for unified collection.

[0063] In order to ensure that the components of the vortex assist assembly 13 can be stably assembled and effectively generate spiral airflow, the following technical solutions are provided.

[0064] A guide head 136 arranged in the jet tube 132 is fixedly connected to the bottom axis of the connecting seat 131, and a connecting ring plate 137 is fixedly connected to the periphery of the jet tube 132. The air supply ring pipe 134 and the air collecting sleeve 133 are respectively fixed to the upper and lower sides of the connecting ring plate 137. The bottom port of the jet tube 132 is set to a closed shape, and the outer wall of the air collecting sleeve 133 is connected to the exhaust pipe 138.

[0065] The guide head 136 can cooperate with the closing section at the bottom of the jet tube 132 to guide the spiral airflow to ensure the stable output of the spiral airflow. The setting of the connecting ring plate 137 can ensure the stable installation of the air supply ring pipe 134 and the air collecting hood. The air supply ring pipe 134 is fixed to the connecting ring plate 137 through the annular support 139. The exhaust pipe 138 in each group of vortex auxiliary components 13 is integrated and connected to the exhaust pump, thereby ensuring that the airflow with moisture can be effectively retracted.

[0066] The heating device 11 may be an irradiation lamp or a laser array to efficiently heat the paper 6 .

[0067] Example 4

[0068] See also Figure 3 、 Figure 7In order to ensure that the flattening assembly 2 can be stably assembled into the flattening chamber 52 and realize stable pressurization and operation of the flattening assembly 2, the following technical solutions are provided.

[0069] A guide shaft 523 arranged vertically upward is fixed to the top of the flattening chamber 52, and the assembly bracket 22 is slidably installed on the guide shaft 523. The hydraulic telescopic cylinder 23 is fixedly installed to the top of the flattening chamber 52 and the movable end is fixedly connected to the assembly bracket 22. A strip-shaped through groove is opened on the side wall of the flattening chamber 52, and the end of the pressure roller 21 is arranged to pass through the strip-shaped through groove.

[0070] The setting of the guide shaft 523 can ensure that the assembly bracket 22 can be stably raised and lowered in the vertical direction. The assembly bracket 22 and the matching pressure roller 21 can be driven to rise and fall in the vertical direction through the telescopic movement of the hydraulic telescopic cylinder 23, and the pressure roller 21 can provide a certain tensioning effect on the paper 6.

[0071] The provision of the strip-shaped through groove can avoid spatial motion interference between the lifting and lowering adjustment pressure roller 21 and the mounting hood 5 , thereby ensuring that the pressure roller 21 can be stably assembled on the assembly bracket 22 .

[0072] Example 5

[0073] See also Figure 3 、 Figure 8-Figure 9 In order to ensure that the heat exchange component 4 can be stably installed in the pressure roller 21 and the heat dissipation roller 31, and to ensure that the heat exchange component 4 can achieve effective heat exchange between the pressure roller 21 and the heat dissipation roller 31, the following technical solutions are provided.

[0074] The pressure roller 21 and the heat dissipation roller 31 are respectively provided with an assembly cavity A211 and an assembly cavity B311. The ends of the pressure roller 21 and the heat dissipation roller 31 are rotatably connected to the ventilation plate A24 and the ventilation plate B32 respectively. The ventilation plate A24 is fixedly mounted on the assembly bracket 22, and the ventilation plate B32 is fixedly mounted on the outer wall of the heat dissipation chamber 53. The assembly cavity A211 and the assembly cavity B311 are both equipped with a heat exchange component 4.

[0075] The setting of the ventilation plate A24 and the ventilation plate B32 can stably connect the pipes for inputting and outputting air, thereby ensuring that the gas can always effectively pass through the pressure roller 21 and the heat dissipation roller 31 when the pressure roller 21 and the heat dissipation roller 31 are in operation, thereby realizing efficient heat exchange of the pressure roller 21 and the heat dissipation roller 31 with the heat exchange component 4 assembled therein.

[0076] For the pressure roller 21, high-temperature hot air flows into its assembly cavity A211, efficiently heating the outer wall of the pressure roller 21 through heat transfer from the matching heat exchange assembly 4. For the heat dissipation roller 31, natural air flows into its assembly cavity B311. Through heat transfer from the matching heat exchange assembly 4, residual heat from the paper 6 is transferred to the natural air through the heat dissipation roller 31 and the heat exchange assembly 4, and then discharged to the outside.

[0077] On the basis of the above technical solutions, in order to ensure that the heat exchange component 4 can be stably installed in the assembly cavity A211 and the assembly cavity B311 and efficiently exchange heat for the pressure roller 21 and the heat dissipation roller 31, the following technical solutions are provided.

[0078] The heat exchange component 4 includes a heat transfer tube 41, a solid disk 42, and a hollow disk 43. The solid disk 42 and the hollow disk 43 are arranged alternately and are in contact with the inner walls of the assembly cavity A211 and the assembly cavity B311. A heat transfer tube 41 is fixedly connected between two adjacent groups of solid disks 42, and the hollow disk 43 is fixedly connected to the outer periphery of the heat transfer tube 41. Ventilation holes A411 are evenly opened on the side wall of the heat transfer tube 41, and ventilation holes B421 are evenly opened on the solid disk 42.

[0079] The two ends of the heat transfer tube 41 are kept in contact with the ends of the assembly cavity A211 and the assembly cavity B311. When the gas is transmitted from one end of the assembly cavity A211 or the assembly cavity B311 to the other end, it first enters the heat transfer tube 41 and flows to the outside of the heat transfer tube 41 through the vent A411, and then re-enters the heat transfer tube 41 through the vent B421 and the subsequent vent B421. According to this principle, the flow route and duration of the gas in the assembly cavity A211 and the assembly cavity B311 can be effectively extended, thereby fully contacting and efficiently exchanging heat with the various components of the heat exchange component 4 and the pressure roller 21 or the heat dissipation roller 31.
