Description

Technical Field

[0001] This utility model relates to the field of tarpaulin drying technology, and in particular to a rapid drying device for tarpaulin coating. Background Technology

[0002] Canvas, as a high-strength, wear-resistant, and highly flexible material, is widely used in various fields such as logistics and transportation tarpaulins, outdoor tents, agricultural greenhouse coverings, and port and dock cargo yard protection. To further enhance the core properties of tarpaulins, such as waterproofing, stain resistance, aging resistance, and corrosion resistance, the industry commonly employs a processing technique that coats the surface of the tarpaulin substrate with functional coatings such as PVC (polyvinyl chloride), polyurethane, and acrylate. The quality of the coating directly determines the performance and service life of the tarpaulin.

[0003] In the coating process of tarpaulin, the drying and curing of the coating layer is a critical step. If the coating is not dried in a timely and uniform manner, it will not only lead to a decrease in the adhesion between the coating and the substrate, but also easily cause defects such as coating sagging, wrinkles, bubbles, and cracks, seriously affecting the appearance and reliability of the tarpaulin. At the same time, the incompletely cured coating is prone to sticking together during subsequent winding and cutting processes, resulting in product scrap. Therefore, the drying efficiency, heat utilization rate, and drying uniformity of the drying equipment are directly related to the production efficiency, product quality, and production cost of tarpaulin.

[0004] Traditional drying devices mostly adopt a single-cavity structure, where high-temperature hot air generated by a heater is directly blown onto the coated canvas. After one drying cycle, the hot air is directly discharged outside the equipment, resulting in a large amount of waste heat that is not recovered and utilized, leading to serious energy waste and high drying energy consumption. To address this, this utility model proposes a novel solution. Utility Model Content

[0021] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0022] Please see Figure 1-9 This utility model provides a technical solution: a rapid drying device for tarpaulin coating. The base 1 serves as the core support benchmark for the entire device and is made of high-strength alloy material to ensure structural stability when supporting components such as the tarpaulin coating machine 2 and the tarpaulin drying box 3. It is suitable for the vibration environment of continuous industrial production and provides a basic guarantee for the precise coordination of various functional components.

[0023] The canvas coating machine 2 is installed on the upper left side of the base 1 to complete the functional coating operation of the canvas. Its discharge end is precisely aligned with the left inlet of the canvas drying box 3 to ensure that the coated canvas can be smoothly conveyed to the drying area and avoid damage to the coating due to conveying deviation.

[0024] The tarpaulin drying oven 3 is fixedly installed at the upper middle part of the base 1. Openings for tarpaulin to pass through are provided on its left and right sides and in the middle of the internal partition 15. The edges of the openings are designed with smooth chamfers to prevent scratching the surface of the coated tarpaulin. The front side of the drying oven 3 is fixed with a maintenance plate 7 by bolts. The bolt connection method takes into account both stability and disassembly, which facilitates the maintenance and cleaning of the internal components in the later stage.

[0025] The drying oven 3 is fixedly connected to a partition 15, which divides the interior of the drying oven 3 into two functional areas to achieve staged drying. The inner wall of the drying oven 3 is also fixedly connected to a first support plate 16 and a second support plate 17, which are located on the left and right sides of the partition 15, respectively. The surface of the second support plate 17 has multiple through grooves to provide channels for hot air circulation.

[0026] The upper end of the drying oven 3 is fixedly connected to a first air guide box 8 and a second air guide box 11, which correspond to the main drying area and the preheating area, respectively. The first air guide box 8 is Y-shaped, with its two lower vertical ends penetrating the second support plate 17. Multiple heating tubes 20 and optional staggered third air guide plates 24 are fixedly connected to its inner wall. Multiple first air guide plates 21 are fixedly connected to the inner wall of the horizontal end, and multiple second air guide plates 23 are fixedly connected to the opposite surfaces of the two vertical ends. Multiple ventilation slots 22 are opened on the surface of each air guide box to achieve uniform distribution of hot air and full heating. The bottom of the inner wall of the second air guide box 11 is also fixedly connected to multiple first air guide plates 21 and has multiple ventilation slots 22 to guide the uniform diffusion of residual heat and hot air.

[0027] A first fan 9 is installed at the top of the first air guide box 8, and a filter box 10 is installed at the top of the first fan 9. A filter screen is fixedly connected inside the filter box 10 to filter dust and impurities in the air and prevent contamination of the uncured coating. A second fan 12 is installed at the top of the second air guide box 11. A connecting pipe 13 is fixedly connected to the right side of the top of the drying box 3. One end of the connecting pipe 13 is fixed to the second fan 12, and the other end extends into the main drying area of ​​the drying box 3 to form a waste heat recovery channel. An exhaust pipe 14 is fixedly connected to the left side of the top of the drying box 3 to discharge waste gas and balance the air pressure inside the box.

[0028] Support rollers 18 are rotatably connected to the left and right sides of the drying chamber 3. The support rollers 18 are made of wear-resistant rubber material. By rotating, they reduce the friction during the conveying of the tarpaulin, ensuring that the uncured coating is not pulled or damaged after coating. A first support frame 4 is fixedly connected to the upper end of the base 1. The first support frame 4 is located inside the drying chamber 3 and is equipped with a second collection box 6. The first collection box 5 and the second collection box 6 collect the dripping coating material. The second collection box 6 is replaced by a fixedly installed guide frame 19 at the upper end of the first support frame 4. The bottom of the guide frame 19 has an inclined structure with "high in the middle and low on the left and right sides". Two first collection boxes 5 are slidably connected to the upper end of the base 1. They are located on the left and right sides of the first support frame 4 and are precisely aligned with the edges of the guide frame 19 on both sides to collect excess coating.

[0029] Working principle: Before the device starts working, the base 1 provides stable support for the entire equipment. After the canvas coating machine 2 completes the functional coating of the canvas, the coated canvas is smoothly guided into the canvas drying box 3 by the support rollers 18 that are rotatably connected on the left and right sides. The support rollers 18 reduce the friction during the canvas conveying process by rotating, so as to avoid scratches or damage to the coating due to pulling. The canvas passes through the left opening of the canvas drying box 3, the middle opening of the partition 15, and finally exits from the right opening to complete the drying process.

[0030] The left side of the canvas drying box 3 is the preheating zone, and the right side is the main drying zone. The interior of the canvas drying box 3 is divided into two functional areas by a partition 15 to achieve precise drying in stages. The generation and delivery of hot air in the main drying zone are completed collaboratively by the first air guide box 8, the first fan 9, the heating pipe 20, and the filter box 10. After the first fan 9 is started, outside air is drawn in and passes through the filter box 10. The filter screen inside the filter box 10 can filter dust and impurities in the air, preventing pollutants from adhering to the uncured coating surface and ensuring the appearance quality of the tarpaulin.

[0031] The filtered clean air enters the Y-shaped first air guide box 8. Multiple heating tubes 20 fixed on the inner wall of the first air guide box 8 are energized and heat up to produce high-temperature hot air.

[0032] Multiple first air guide plates 21 on the inner wall of the horizontal end of the first air guide box 8, multiple second air guide plates 23 on the opposite sides of the two vertical ends, and multiple ventilation slots 22 on the surface work together to guide the high-temperature hot air to be evenly distributed, so that the hot air passes through the slots on the surface of the second support plate 17 and fully covers the surface of the tarpaulin in the main drying area, thereby achieving deep drying and curing of the coating.

[0033] To solve the problem of waste heat in traditional equipment, this device constructs a waste heat recovery and circulation system through a second fan 12, a connecting pipe 13, and a second air guide box 11, so as to use the waste heat in the main drying area to preheat the tarpaulin that has just entered the drying box. After the hot air in the main drying zone completes one drying cycle, it still retains a certain temperature (residual heat). The second fan 12 is started, and the air with residual heat is drawn out from the main drying zone through the connecting pipe 13 and transported to the second air guide box 11 located in the preheating zone.

[0034] Multiple first air guide plates 21 and ventilation slots 22 at the bottom of the inner wall of the second air guide box 11 evenly guide the residual hot air to the preheating zone, preheating the coated canvas that has just entered the drying box at a low temperature, thus avoiding the coating from experiencing a sudden temperature rise due to direct contact with high-temperature hot air, which could lead to defects such as bubbles and wrinkles.

[0035] The preheating process not only improves the uniformity of coating drying, but also fully recovers and utilizes waste heat, significantly reducing the energy consumption of heating tube 20 and achieving energy-saving and efficient drying.

[0036] The small amount of waste gas and excess hot air generated during the drying process are discharged through the exhaust pipe 14 on the upper left side of the tarpaulin drying box 3 to ensure stable air pressure inside the box and avoid affecting the hot air circulation and tarpaulin conveying due to excessive air pressure.

[0037] Excess coating material dripping from the surface of the coated canvas will fall into the second collection box 6, which can be detachably installed on the upper end of the first support frame 4, and the two first collection boxes 5, which are slidably connected to the upper end of the base 1. The two first collection boxes 5 are located on the left and right sides of the first support frame 4, respectively, so as to realize the recycling and reuse of coating material and keep the inside of the equipment clean.

[0038] The inspection plate 7, which is fixed to the front of the canvas drying box 3 by bolts, can be quickly disassembled during equipment maintenance. This allows operators to easily inspect, clean, or replace components such as the collection box inside the drying box, ensuring long-term stable operation of the equipment.

[0039] Furthermore, this utility model divides the tarpaulin drying box 3 into a preheating zone and a main drying zone through the partition 15, and constructs a closed-loop waste heat recovery system with the second fan 12, connecting pipe 13 and second air guide box 11 to solve the problem of waste heat waste in traditional devices; the warm air after the drying operation in the main drying zone is drawn by the second fan 12 and transported to the second air guide box 11 through the connecting pipe 13, and then evenly guided to the preheating zone by the first air guide plate 21 and ventilation groove 22 on the inner wall of the second air guide box 11, to preheat the coated tarpaulin that has just entered the drying box; thereby improving the heat recovery and utilization rate, significantly reducing the energy consumption load of the heating pipe 20, and effectively solving the core defect of high energy consumption in traditional single-cavity devices.

[0040] The device adopts a staged drying mode of "preheating + main drying" to avoid defects such as sagging, wrinkles, and bubbles in the coating due to sudden temperature rise. The preheating zone uses residual heat to gently raise the temperature of the low-temperature canvas, laying the foundation for deep curing in the main drying zone. In the main drying zone, the first air guide box 8 has a "Y"-shaped structure. Together with the internal first air guide plate 21, second air guide plate 23, and ventilation groove 22, it evenly distributes the high-temperature hot air heated by the heating tube 20. The air is then fully covered on the surface of the canvas through the groove of the second support plate 17, achieving uniform curing of the coating. This improves the adhesion between the coating and the substrate after drying, resulting in excellent appearance smoothness and effectively reducing the product scrap rate.

[0041] The first collection box 5 at the top of the base 1 and the second collection box 6 at the top of the first support frame 4 form a multi-stage coating recycling structure, which can quickly collect excess coating material dripping from the coated canvas and achieve recycling and reuse; it not only reduces coating waste and lowers production costs, but also keeps the inside of the equipment clean and avoids impurities from affecting the drying effect.

[0042] Example 1: High-efficiency flow-guiding and collection drying device (suitable for large-scale PVC coating production line scenarios) The original detachable second collection box 6 installed on the upper end of the first support frame 4 was removed, and a fixed connection structure was adopted: the guide frame 19 was fixedly connected to the upper end of the first support frame 4 by welding to ensure structural stability and adaptability to the vibration environment of continuous production.

[0043] The bottom of the flow guide frame 19 is designed as an inclined structure with a "high in the middle and low on the left and right sides" and the inclination angle is set to 15°-20°. Its left and right side edges are precisely aligned with the upper openings of the two first collection boxes 5 to ensure that the flow path is without deviation.

[0044] This embodiment achieves continuous collection without stopping the machine for disassembly through the coordinated design of the flow guide 19 and the first collection box 5, thereby improving production efficiency. The replaced flow guide 19 has a tilt structure without dead angles to avoid coating residue and extend the equipment cleaning cycle. It also improves the recovery rate of excess coating, reduces material waste, lowers production costs, and meets the high-intensity requirements of large-scale continuous PVC coating production.

[0045] Example 2: Uniform heating drying device (suitable for high-precision polyurethane coating production scenarios) Multiple staggered third air guide plates 24 are fixedly connected to the inner wall of the first air guide box 8, and the third air guide plates 24, the inner wall of the first air guide box 8, and the first air guide plate 21 form a meandering flow channel.

[0046] The third air guide plate 24 is made of aluminum alloy with excellent thermal conductivity. Its surface is smooth and burr-free, which avoids turbulence when the air flows. At the same time, it extends the air flow distance inside the first air guide box 8 and reduces the flow speed.

[0047] The heated air is divided by the first air guide plate 21 and the second air guide plate 23, and then blown evenly onto the surface of the canvas in the main drying area through the ventilation groove 22 and the groove of the second support plate 17. With the help of the waste heat preheating system, the polyurethane coating is precisely cured.

[0048] This embodiment solves the technical defects of uneven heating in traditional methods through the structural design of the third air guide plate 24: it improves the qualified rate of polyurethane coating drying and significantly reduces the rate of defects such as color difference and cracks; the air is in full contact with the heating tube 20, improving heating efficiency and effectively saving energy; at the same time, it is suitable for drying various high-precision coatings that are sensitive to temperature, and has strong versatility.

[0049] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
