Description

Technical Field

[0001] This utility model relates to the field of printing technology, and more specifically, to a printing roller drying device with waste heat recovery function. Background Technology

[0002] The printing roller drying device is a core piece of equipment in the printing industry that ensures rapid ink curing and improves printing quality. Its design needs to be tailored to printing processes, printing roller materials, and environmental protection requirements. The printing roller drying device accelerates the evaporation of solvents in the ink or triggers chemical reactions through heat or light energy to achieve ink curing.

[0003] When drying printed materials using thermal drying methods on printing rollers, a dedicated drying mechanism is required. However, the heat generated by the internal drive structure during the operation of the printing roller drying device is not easily utilized, resulting in waste. If traditional equipment directly utilizes the heat generated by the drive structure, the significant temperature difference between this heat and the temperature during drying can easily lead to uneven ink drying. Therefore, we propose a printing roller drying device with waste heat recovery functionality. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a printing roller drying device with waste heat recovery function to solve the technical problem that the current printing roller drying device is prone to uneven drying due to the direct use of the equipment's waste heat.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a printing roller drying device with waste heat recovery function, including a box body and two drive boxes located on the box body. A waste heat recovery drying mechanism is provided on the opposite side of the two drive boxes. The waste heat recovery drying mechanism includes a drying box, a heat exchange box is provided on the drying box, a centralized air inlet plate is provided on the heat exchange box, and a plurality of air inlets communicating with the centralized air inlet plate are provided on the drying box. A heat collection plate is provided on the drive box. A drive motor assembly is provided at one end of the heat collection plate connected to the drive box. The end of the heat collection plate away from the drive box passes through the drying box and is connected to the heat exchange box. The heat collection plate is provided with double-sided heat distribution plates.

[0006] Preferably, a printing roller assembly is provided on one side of each of the two drive boxes, the printing roller assembly is connected to the drive equipment in the drive box, and the waste heat recovery drying mechanism is located at the output end of the printing roller assembly.

[0007] Preferably, the drying box is provided with a feed inlet and a corresponding discharge outlet. The air inlet of the waste heat recovery drying mechanism is located at the top of the corresponding position of its discharge outlet, and the air inlet is in the form of a vertical elliptical structure. The air inlet is connected to the heat exchange box through a centralized air inlet plate.

[0008] Preferably, the drying box is provided with a heat collection groove for inserting and fixing the heat collection plate, and the heat collection plate passes through the heat collection groove and the centralized air inlet plate and is connected to the heat exchange box.

[0009] Preferably, the output end of the heat exchange box is connected to a vertical side heat plate, and a heat equalization plate is provided on one side of the side heat plate and is connected to it. The output end of the heat equalization plate is located between the feed inlet and the discharge outlet, and the output end of the heat equalization plate is horizontally inclined and the inclination direction is the same as that of the feed inlet.

[0010] Preferably, the output end of the drive motor assembly is connected to the heat collection plate, the heat collection plate is generally arc-shaped, and the double-sided heat distribution plate inside it is attached to the arc-shaped structure. The double-sided heat distribution plate is arc-shaped and crosses each other, dividing the inside of the heat collection plate into four tubular slots of different sizes.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model designs a waste heat recovery drying mechanism structure. Installed at the output position of the printing roller assembly, the printed material is output through the feed inlet via a drying chamber. As it passes the heat equalization plate in the drying chamber, the heat mixed by the heat exchanger is output through the side heat plate and reaches the heat equalization plate, thus drying the printed material above the heat equalization plate and within the overall drying chamber. By connecting the heat exchanger to the heat collection plate, waste heat in the drive chamber is recovered and initial heat is mixed, eliminating the need for direct mixing at the drying point. This reduces uneven drying caused by air mixing of printed materials at different temperatures, improving drying performance while simultaneously recovering waste heat from the equipment drive. This solves the technical problem of uneven drying caused by directly utilizing waste heat in current printing roller drying devices.

[0012] 2. This utility model also designs a heat collection plate structure, which is connected to the drive box via a drive motor assembly. The heat collection plate adopts an arc-shaped structure. The heat located in the drive box is output to the heat exchange box through the double-sided heat distribution plates located in the heat collection plate, forming air with different flow rates. It mixes with the original high-temperature air in the heat exchange box. The heat recovered here can save more energy than the traditional direct heating through heating equipment, reducing energy waste. At the same time, when the heat is output at different flow rates through the double-sided heat distribution plates, a flow difference is formed. In the heat exchange box, it is avoided that too much lower temperature air mixes with higher temperature air, causing a temperature difference and resulting in more heat exchange and energy waste. This realizes waste heat recovery while reducing energy waste. At the same time, heat mixing does not occur at the printing material, reducing the occurrence of uneven drying.

Detailed Implementation

[0015] like Figures 1 to 5 As shown, this utility model relates to a printing roller drying device with waste heat recovery function, including a box body 100 and two drive boxes 120 located on the box body 100. A waste heat recovery drying mechanism 200 is provided on the opposite side of the two drive boxes 120. The waste heat recovery drying mechanism 200 includes a drying box 210. A heat exchange box 250 is provided on the drying box 210. A centralized air inlet plate 240 is provided on the heat exchange box 250. A plurality of air inlets 230 communicating with the centralized air inlet plate 240 are provided on the drying box 210. A heat collection plate 130 is provided on the drive box 120. A drive motor assembly 140 is provided at one end of the heat collection plate 130 connected to the drive box 120. The end of the heat collection plate 130 away from the drive box 120 passes through the drying box 210 and is connected to the heat exchange box 250. The heat collection plate 130 is provided with a double-sided heat distribution plate 131.

[0016] This invention designs a waste heat recovery drying mechanism 200, which is installed at the output position of the printing roller assembly 110. The printed material is output through the feed inlet 220 via the drying chamber 210. When it passes through the heat equalization plate 270 in the drying chamber 210, the heat mixed by the heat exchange box 250 is output through the side heat plate 260 and reaches the heat equalization plate 270, thereby drying the printed material above the heat equalization plate 270 and inside the overall drying chamber 210. By connecting the heat collection plate 130 to the heat exchange box 250, the waste heat in the drive box 120 is recovered and the initial heat is mixed, eliminating the need for direct mixing at the drying point. This reduces the uneven drying caused by air mixing of printed materials at different temperatures, improves drying performance, and achieves the purpose of recovering the waste heat of the equipment drive. This solves the technical problem that current printing roller drying devices easily cause uneven drying by directly using the waste heat of the equipment.

[0017] This invention also designs a heat collection plate 130 structure, which is connected to the drive box 120 via a drive motor assembly 140. The heat collection plate 130 adopts an arc-shaped structure. The heat located in the drive box 120 is output to the heat exchange box 250 through the double-sided heat distribution plates 131 located in the heat collection plate 130, forming air with different flow rates. It mixes with the original high-temperature air in the heat exchange box 250. The heat recovered here can save more energy than the traditional direct heating through heating equipment, reducing energy waste. At the same time, when the heat is output at different flow rates through the double-sided heat distribution plates 131, a flow difference is formed. In the heat exchange box 250, it is avoided that too much lower temperature air mixes with higher temperature air, causing a temperature difference and resulting in more heat exchange and energy waste. This realizes waste heat recovery while reducing energy waste. At the same time, heat mixing is not carried out at the printing material, reducing the occurrence of uneven drying.

[0018] Specifically, a printing roller assembly 110 is provided on one side of each of the two drive boxes 120. The printing roller assembly 110 is connected to the drive device inside the drive box 120 for driving. The waste heat recovery drying mechanism 200 is located at the output end of the printing roller assembly 110. The printing roller assembly 110 is connected to the output end of the drive box 120 for regular printing operations. The waste heat recovery drying mechanism 200 is installed on the printing roller assembly 110 at the position before the output after printing to ensure that the printed material can be dried quickly, reducing the occurrence of blurred printed materials due to the ink remaining wet for a long time.

[0019] Furthermore, the drying chamber 210 is provided with a feed inlet 220 and a corresponding discharge outlet. The air inlet 230 of the waste heat recovery drying mechanism 200 is located at the top of the corresponding position of its discharge outlet, and the air inlet 230 has a vertical elliptical structure. The air inlet 230 is connected to the heat exchange box 250 through a centralized air intake plate 240. The feed inlet 220 and discharge outlet on the drying chamber 210 realize the entry and exit of printed materials. The drying chamber 210 and its internal structure realize the operation of uniform drying of printed materials, reducing heat loss and realizing the purpose of waste heat recovery and heat output. The installation position of the air inlet 230 will not affect the overall structure of the drying chamber 210. At the same time, it realizes the input of external air to realize the operation of the heat exchange box 250. The centralized air intake plate 240 realizes the purpose of overall air intake, improving the overall integrity without affecting the connection and fixation of the heat collection plate 130.

[0020] It is worth noting that the drying box 210 is provided with a heat collection groove 280 for inserting and fixing the heat collection plate 130. The heat collection plate 130 passes through the heat collection groove 280 and the centralized air inlet plate 240 and is connected to the heat exchange box 250. The installation of the heat collection groove 280 facilitates the insertion and fixing of the heat collection plate 130. At the same time, the heat collection groove 280 passes through the centralized air inlet plate 240, which will not affect the operation of the centralized air inlet plate 240 while achieving the purpose of waste heat recovery.

[0021] It is worth mentioning that the output end of the heat exchange box 250 is connected to a vertical side heat plate 260. A heat equalization plate 270 is provided on one side of the side heat plate 260 and communicates with it. The output end of the heat equalization plate 270 is located between the feed inlet 220 and the discharge outlet. The output end of the heat equalization plate 270 is laterally inclined, and the inclination direction is the same as that of the feed inlet 220. The heat exchange box is a box structure with air heating function. Air heating is existing technology, so it will not be described in detail. The part is provided with a hole connected to the output end of the heat collection plate 130, so that the low temperature air in the heat collection plate 130 is output to the heat exchange box 250 and mixed with the air pre-input from the centralized air intake plate 240. A valve body is provided between the centralized air intake plate 240 and the heat exchange box 250. The air in the centralized air intake plate 240 is pre-input and therefore in a high temperature state. In subsequent use, the air intake of the centralized air intake plate 240 can be adjusted according to the drying state. More air can be output from the heat collection plate 130 to achieve waste heat recovery.

[0022] It is worth noting that the output end of the drive motor assembly 140 is connected to the heat collection plate 130. The heat collection plate 130 has an overall arc-shaped structure, and its internal double-sided heat distribution plate 131 fits into the arc-shaped structure. The double-sided heat distribution plate 131 is arc-shaped and crosses each other, dividing the interior of the heat collection plate 130 into four tubular slots of different sizes. The input end of the drive motor assembly 140 is connected to the drive box 120. The drive motor assembly 140 is a motor structure with adjustable airflow. By rotating the output end of the motor, the air in the drive box 120 is output to the heat collection plate 130 through the output end. The double-sided heat distribution plate 131 on the heat collection plate 130 then regulates the airflow, so that the air output to the heat exchange box 250 is heated at different positions, reducing the occurrence of excessive heat difference caused by concentrated output.

[0023] Working Principle: This embodiment provides a printing roller drying device with waste heat recovery function. In use, the material to be printed is passed through the printing roller assembly 110 and simultaneously through the waste heat recovery drying mechanism 200. The drive box 120 on the housing 100 drives the printing roller assembly 110 to move the material for printing. When the ink-coated material enters the output end of the heat equalization plate 270 through the feed inlet 220 on the waste heat recovery drying mechanism 200, it undergoes a drying operation. The drying energy of the heat equalization plate 270 is first generated by the heat exchange box 250 and then output to the heat equalization plate 270 via the side heat plate 260. While the heat exchange box 250 generates heat itself, the heat generated by the operation of the equipment in the drive box 120 is guided and output to the heat collection plate 130 through the drive motor assembly 140. After passing through the double-sided heat distribution plates 131 on the heat collection plate 130, the generated heat is output to the heat exchange box 250 through holes of different sizes. At the same time, the heat exchange box 250 is heated by air intake from the outside through several air inlets 230 on the drying box 210. The lower heat entering the heat collection plate 130 is concentrated and mixed and output through the conventional heat exchange box 250. Finally, it is output through the heat equalization plate 270 to dry the printing material with ink.
