Description

Technical Field

[0001] This utility model relates to the field of ribbon production equipment technology, and in particular to a structure for preventing condensate backflow in a ribbon drying device. Background Technology

[0002] Webbing products are typically printed with logos and other designs using screen printing. To prevent undried ink from contaminating non-printed areas of the webbing, traditional methods, such as the webbing drying platform disclosed in publication number CN218986096U, use a drying hood to heat the conveyed webbing to evaporate moisture and then remove the water vapor through an exhaust pipe. However, as the exhaust pipe extends away from the drying hood, water droplets gradually condense on its inner wall. These droplets drip onto the conveyor platform under gravity, which negatively impacts the drying effect of the ink on the webbing surface. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a structure for preventing condensate backflow in a webbing drying device, so as to prevent condensed water droplets from dripping onto the conveyor platform.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a structure for preventing condensate backflow in a webbing drying device, including a drying hood set above a conveying platform, an exhaust pipe for discharging air from the drying hood, the exhaust pipe including a rigid pipe and a flexible pipe, the rigid pipe being set on the drying hood, the flexible pipe communicating with the rigid pipe, a first water-blocking ring being provided on the inner wall of the rigid pipe along its circumference, the first water-blocking ring and the inner wall of the rigid pipe forming a first water storage tank with the opening facing the air outlet of the rigid pipe, and a drain outlet communicating with the first water storage tank being provided on the wall of the rigid pipe.

[0005] Furthermore, the first water-blocking ring is located at the air inlet end of the rigid pipe.

[0006] Furthermore, the maximum width of the opening of the first water storage tank is 3mm to 8mm.

[0007] Furthermore, the depth of the first water storage tank is 5cm to 10cm, and the diameter of the drain outlet is 6mm to 10mm.

[0008] Furthermore, the drain outlet is located 1cm to 2cm above the bottom of the first water storage tank.

[0009] Furthermore, the outer wall of the rigid pipe is provided with a second water-blocking ring along its circumference. The second water-blocking ring and the outer wall of the rigid pipe enclose a second water storage tank with the opening facing the air outlet of the rigid pipe. The second water storage tank is connected to the drain outlet.

[0010] Furthermore, the depth of the second water storage tank is 5cm to 10cm.

[0011] Furthermore, the outer wall of the exhaust pipe is wrapped with insulating cotton.

[0012] The beneficial effects of this utility model are as follows: the exhaust pipe is designed as a combination of a rigid pipe and a flexible pipe, wherein the rigid pipe is responsible for connecting the inner cavity of the drying hood, and the flexible pipe is used to connect to the workshop exhaust system; at the same time, a first water-blocking ring is added to the inner wall of the rigid pipe, and the first water-blocking ring and the inner wall of the rigid pipe together form an annular first water storage tank, so that when water vapor condenses in the pipe and flows back along the inner wall, it can be intercepted and collected by the first water storage tank, thereby preventing the condensate from dripping onto the conveying platform, and the finally collected condensate can be discharged through the drain outlet.

[0020] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0021] Please refer to Figure 1 and Figure 2 As shown, the present invention discloses a condensate backflow prevention structure for a webbing drying device, comprising a drying hood 1 disposed above a conveying platform, an exhaust pipe 2 disposed on the drying hood 1 for discharging air from the drying hood 1, the exhaust pipe 2 comprising a rigid pipe 21 and a flexible pipe 22, the rigid pipe 21 disposed on the drying hood 1, the flexible pipe 22 communicating with the rigid pipe 21, a first water-blocking ring 3 disposed on the inner wall of the rigid pipe 21 along its circumference, the first water-blocking ring 3 and the inner wall of the rigid pipe 21 forming a first water storage tank 4 with the groove facing the air outlet end of the rigid pipe 21, and a drain outlet 5 disposed on the wall of the rigid pipe 21 communicating with the first water storage tank 4.

[0022] Working principle: The exhaust pipe 2 is designed as a combination of a rigid pipe 21 and a flexible pipe 22. The rigid pipe 21 is responsible for connecting to the inner cavity of the drying hood 1, while the flexible pipe 22 is used to connect to the workshop exhaust system. At the same time, a first water-blocking ring 3 is added to the inner wall of the rigid pipe 21. The first water-blocking ring 3 and the inner wall of the rigid pipe 21 together form an annular first water storage tank 4. This allows water vapor to be intercepted and collected by the first water storage tank 4 when it condenses in the pipe and flows back along the inner wall, thus preventing condensate from dripping onto the conveying platform. Finally, the collected condensate can be discharged through the drain outlet 5.

[0023] The preferred first water-blocking ring 3 is installed on the inner wall of the rigid pipe 21 by welding or adhesive bonding.

[0024] In some embodiments, the first water-blocking ring 3 is located at the air inlet end of the rigid pipe 21. Since the temperature around the exhaust pipe 2 is close to the water vapor temperature as it gets closer to the drying hood 1, water vapor is less likely to condense there. Therefore, placing the first water-blocking ring 3 at the air inlet end of the rigid pipe 21 can minimize the condensation of water vapor below the first water-blocking ring 3.

[0025] It is worth noting that the connection between the first water-blocking ring 3 and the inner wall of the rigid pipe 21 is located 1cm to 2cm deep into the air inlet of the rigid pipe 21.

[0026] In some implementations, please refer to Figure 1 As shown, the maximum width of the opening of the first water storage tank 4 is A, which is between 3mm and 8mm. By limiting the width of the opening of the first water storage tank 4, the impact of the first water baffle ring 3 on the exhaust of the exhaust pipe 2 is minimized while still satisfying the requirement of collecting condensate.

[0027] It is worth noting that A includes, but is not limited to, 3mm, 4mm, 5mm, 6mm, 7mm, and 8mm.

[0028] In some implementations, please refer to Figure 1 As shown, the depth of the first water storage tank 4 is B, which is 5cm to 10cm, and the diameter of the drain outlet 5 is C, which is 6mm to 10mm. By limiting the depth of the first water storage tank 4, the condensate collected in the first water storage tank 4 is reduced from spilling out due to the shaking of the drying hood 1. At the same time, limiting the diameter of the drain outlet 5 reduces the possibility of the drain outlet 5 becoming clogged.

[0029] It is worth noting that B includes, but is not limited to, 5cm, 6cm, 7cm, 8cm, 9cm, and 10cm. C includes, but is not limited to, 6mm, 7mm, 8mm, 9mm, and 10mm.

[0030] In some embodiments, the drain outlet 5 is located 1 cm to 2 cm above the bottom of the first water storage tank 4. By ensuring the first water storage tank 4 has sufficient depth and placing the drain outlet 5 1 cm to 2 cm above the bottom of the first water storage tank 4, the amount of exhaust gas entering the first water storage tank 4 and then leaking from the drain outlet 5 can be reduced.

[0031] In some implementations, please refer to Figure 1 As shown, a second water-retaining ring 6 is provided on the outer wall of the rigid pipe 21 along its circumference. The second water-retaining ring 6 and the outer wall of the rigid pipe 21 enclose a second water storage tank 7 with its opening facing the air outlet of the rigid pipe 21. The second water storage tank 7 is connected to the drain outlet 5. By using the second water-retaining ring 6 to form the second water storage tank 7 on the outer wall of the rigid pipe 21, and by connecting the second water storage tank 7 to the first water storage tank 4 through the drain outlet 5, the water level in the first water storage tank 4 can be determined by observing the water level in the second water storage tank 7, so as to promptly remove the collected condensate. At the same time, by adding an appropriate amount of water to the second water storage tank 7, the drain outlet 5 can be sealed with water to prevent exhaust gas from being discharged from the drain outlet 5.

[0032] It is worth noting that the width of the second water storage tank 7 is 1cm to 2cm to facilitate the addition of water to the second water storage tank 7.

[0033] In some embodiments, the depth of the second water storage tank 7 is 5cm to 10cm. Preferably, the depth of the second water storage tank 7 is set to be the same as the depth of the first water storage tank 4, so that the water level in the first water storage tank 4 can be directly observed. This prevents the second water storage tank 7 from being less than the depth of the first water storage tank 4, which could mislead on-site personnel into thinking that the water level in the first water storage tank 4 is too high, or the second water storage tank 7 being more than the depth of the first water storage tank 4, which could mislead on-site personnel into thinking that the water level in the first water storage tank 4 is too low.

[0034] In some embodiments, the outer wall of the exhaust pipe 2 is wrapped with thermal insulation cotton (not shown in the figure) to reduce the influence of the external ambient temperature on the exhaust pipe 2 and minimize the generation of condensate on the inner wall of the exhaust pipe 2.

[0035] It is worth noting that the rigid pipe 21 has a second water-blocking ring 6, so it does not need to be wrapped with insulation cotton.

[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
