[0031] The present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings.
[0032] See also Figures 1 to 3 The guide belt drying mechanism provided in this embodiment includes a main body 100 and a drying device 200.
[0033] The main body 100 has a drying chamber 110 and an air-generating chamber 120. The bottom of the drying chamber 110 is provided with a mounting portion extending in the horizontal direction. The air-generating chamber 120 is provided below the mounting portion. The mounting portion is provided with a drying port 111 connecting the air-generating chamber 120 and the drying chamber 110. There are multiple drying ports 111 and they are evenly distributed on the mounting portion. The drying device 200 includes a heating component 210 and a fan 220. The heating component 210 is provided at the mounting portion. The fan 220 is provided at one end of the air-generating chamber 120. The air outlet direction of the fan 220 is toward the other end of the air-generating chamber 120.
[0034] Specifically, the guide belt drying mechanism in this embodiment is installed below the guide belt of the printing device, and a plurality of drying ports 111 are evenly arranged on the bottom surface of the guide belt and all the drying ports 111 face the bottom surface of the guide belt.
[0035] When the guide belt is driven, the heating component 210 generates heat to heat the air in the drying chamber 110. At the same time, the fan 220 generates airflow, which rises in the drying port 111, thereby driving the hot air in the drying chamber 110 to rise in a vertical direction. After passing through the air outlet chamber, the hot air contacts the bottom surface of the guide belt through the drying port 111 to heat the moisture on the surface of the guide belt, thereby drying the moisture on the surface of the guide belt.
[0036] The guide belt drying mechanism provided in this embodiment generates heat through the heating component 210, and combines with a single fan 220 to generate an upward airflow below to drive the heat to rise and contact the guide belt, thereby achieving drying of the surface of the guide belt, without the need to set up multiple fans 220 and multiple heating elements for use, and the structure is simple and easy to maintain. In this embodiment, the heating component 210 includes multiple heating modules. The heating modules are arranged in the drying port 111, and the multiple heating modules are arranged in a one-to-one correspondence with the multiple drying ports 111.
[0037] The heating module has a long service life and high electric-heat conversion efficiency. Multiple heating modules heat multiple drying ports 111 individually, which can ensure uniform heat at each position and a more stable drying effect.
[0038] In this embodiment, a support isolation net is provided on the top of the drying opening 111. The support isolation net is located between the heating module and the drying chamber 110.
[0039] Specifically, the bracket isolation net in this embodiment includes a bracket for installing the heating module and an isolation net between the heating module and the drying chamber 110. The bracket is used to install the heating module to ensure that the connection structure of the heating module is stable. The isolation net can protect the heating module and prevent debris from falling into the drying port 111 during the drying process and damaging the heating module, causing damage to the heating module.
[0040] In this embodiment, the fan 220 is a cross-flow fan 220 .
[0041] The air intake direction and exhaust direction of the cross flow fan 220 are in the same plane. In this embodiment, the air intake of the cross flow fan 220 is arranged on the side wall of the main body 100 and faces the outside of the main body 100. When the cross flow fan 220 is running, it can inhale the air outside the main body 100 and form a cross wind in the wind production chamber 120, thereby increasing the air pressure in the wind production chamber 120, so that the drying port 111 can form an upward airflow. The exhaust gas of the cross flow fan 220 is evenly distributed along the width direction, and has a simple structure, a small volume, a high dynamic pressure coefficient, and a long distance, and a better wind production effect.
[0042] In this embodiment, a fan 220 isolation net is provided at the air outlet of the cross flow fan 220. The fan 220 isolation net is located between the air outlet of the cross flow fan 220 and the air generating chamber 120.
[0043] The fan 220 isolation net can prevent the debris in the air production chamber 120 from moving toward the cross flow fan 220 and colliding with the cross flow fan 220 under the drive of the air flow, thereby preventing the air outlet of the cross flow fan 220 from being blocked or deformed by collision with the debris.
[0044] In this embodiment, the belt drying mechanism further includes a cold air device 300. The cold air device 300 is disposed on one side of the main body 100 close to the air outlet end, and the air outlet direction of the cold air device 300 is toward the top of the drying chamber 110.
[0045] After the guide belt is dried by the heating assembly 210, some water vapor is likely to remain on the guide belt. In this embodiment, the cooling device 300 is located at the end of the guide belt, that is, the guide belt reaches the top of the cooling device 300 after passing through the heating assembly 210. The cooling device 300 can generate cold air blowing on the guide belt, thereby cooling and further dehumidifying the guide belt, thereby avoiding excessive water vapor remaining on the guide belt.
[0046] In this embodiment, the cooling device 300 includes an air curtain 310 . The air curtain 310 is detachably connected to the main body 100 , and the air outlet of the air curtain 310 faces upward of the main body 100 .
[0047] The air curtain machine 310 uses a high-speed motor to drive a crossflow or centrifugal wind wheel to generate a strong airflow, which blows onto the surface of the guide belt to remove residual water vapor on the guide belt, thereby achieving cold air dehumidification of the guide belt and further improving the dehumidification effect.
[0048] In this embodiment, the belt drying mechanism further includes a water absorbing assembly 400. The water absorbing assembly 400 is disposed on the main body 100 and is located above the drying port 111.
[0049] The water absorption component 400 is above the drying port 111. When the guide belt dryer provided in this embodiment is installed to the bottom of the guide belt, the water absorption component 400 fits the surface of the guide belt. The guide belt can be wiped before and after drying to avoid excessive water on the surface of the guide belt, thereby reducing the drying time and improving the drying efficiency.
[0050] In this embodiment, the water absorbing assembly 400 includes a plurality of water absorbing rollers 410. The plurality of water absorbing rollers 410 are arranged at intervals along the extending direction of the main body 100.
[0051] Specifically, there are three water-absorbing rollers 410 in this embodiment. Among them, a water-absorbing roller 410 is arranged above the side of the main body 100 away from the cross-flow fan 220, which can wipe the guide belt once before the guide belt reaches the top of the drying port 111, thereby reducing the water content on the surface of the guide belt. In addition, two water-absorbing rollers 410 are arranged at intervals in the vertical direction on the side of the main body 100 close to the cross-flow fan 220, and the two water-absorbing rollers 410 are respectively located on both sides of the air curtain machine 310, so as to wipe the guide belt before and after air cooling, thereby ensuring the cleanliness of the guide belt surface.
[0052] The inkjet printer provided in this embodiment includes a frame, a guide belt, a slideway 500, a slider 510 and a guide belt drying mechanism.
[0053] The frame is provided with a transmission roller. The guide belt is connected to the transmission roller. The slideway 500 is provided on the frame and is located below the guide belt. The extension direction of the slideway 500 is the same as the transmission direction of the guide belt. The slider 510 is provided on the slideway 500 and slidably cooperates with the slideway 500. The slider 510 is provided on one side of the main body 100 of the guide belt drying mechanism, and the drying port 111 of the guide belt drying mechanism faces the bottom surface of the guide belt.
[0054] Specifically, in this embodiment, the slideway 500 is disposed on the frame and is located below the guide belt, and both the slideway 500 and the guide belt extend in a horizontal direction.
[0055] In this embodiment, the pull-out structure of the frame and the guide belt drying mechanism is realized by the matching structure of the slider 510 and the slideway 500. The guide belt drying mechanism can slide along the extension direction of the slideway 500. When the guide belt drying mechanism needs to be maintained or parts are replaced, the guide belt drying mechanism can be pulled out along the slideway 500, which makes maintenance and replacement of parts very convenient.
[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit them. Although the utility model has been described in detail with reference to the above embodiments, a person skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some or all of the technical features can be replaced by equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
