Description

Technical Field

[0001] This utility model relates to the field of waterproof membrane production technology, and in particular to an air-cutting and drying device for waterproof membrane carrier fabric. Background Technology

[0002] In the production process of waterproof membrane, waterproof bitumen (or other waterproof materials) needs to be coated onto the carrier fabric to ensure the waterproof effect of the waterproof membrane.

[0003] To ensure the bonding stability between the waterproof asphalt and the carrier fabric, the carrier fabric needs to be cleaned and dried to remove oil stains from its surface. Cleaning the oil stains requires an ultrasonic cleaner, followed by drying. Because the carrier fabric has a high moisture content after cleaning, it cannot be directly placed in an oven for drying; it needs to be dehydrated first.

[0004] To remove moisture from the carrier cloth, a high-pressure airflow can be blown onto the surface of the carrier cloth during the conveying process using an air knife. This allows the high-pressure airflow to carry away the moisture and achieve air-cut drying. However, the moisture is atomized under the action of the high-pressure airflow, and the water mist will increase the humidity of the surrounding air after drifting with the airflow. It may even fall onto the output carrier cloth, causing the carrier cloth to re-wet and affecting the drying efficiency. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this invention is to provide an air-cutting drying device for waterproof membrane carrier fabric, which performs air-cutting drying of the waterproof membrane carrier fabric and avoids the problem of re-wetting of the waterproof membrane carrier fabric caused by water mist.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A wind-cutting drying device for waterproof membrane carrier fabric includes: a frame, air knives, a wet film, a first guide roller, and a second guide roller. The first guide roller is horizontally mounted on the frame, and the second guide roller is mounted on the frame and located above and in front of the first guide roller. The waterproof membrane carrier fabric is vertically conveyed upward from the bottom of the first guide roller and passes through the second guide roller. The air knife is vertically mounted on the frame with its air outlet pointing towards the front of the waterproof membrane carrier fabric. The wet film is vertically mounted on the frame and located on both sides of the waterproof membrane carrier fabric in the width direction.

[0008] The frame is equipped with a water receiving box located below the wet film.

[0009] A drain valve is provided on one side of the water receiving box.

[0010] The water receiving box is equipped with a support that extends upward and supports the wet film.

[0011] The top of the air knife is connected to a compressed air supply pipe.

[0012] The compressed air supply pipe is a flexible hose.

[0013] The frame has two pin seats at the top and bottom to support the swing of the air knife.

[0014] The frame contains a motor located below the air knife. A turntable is mounted on the top shaft of the motor. A first pin is eccentrically mounted on the turntable. A second pin is mounted at the bottom of the air knife. A connecting rod is provided between the first pin and the second pin.

[0015] The beneficial effects of this utility model are as follows: An air-cutting drying device for waterproof membrane carrier fabric, by swinging the air knife left and right, sends airflow to the surface of the vertically upward conveyed waterproof membrane carrier fabric, causing the moisture on the waterproof membrane carrier fabric to form water mist and flow along the width direction. After the water mist comes into contact with the wet film on both sides, it is absorbed by the wet film and flows downward into the water collection box with gravity, avoiding the problem of re-wetting of the waterproof membrane carrier fabric caused by water mist, ensuring the effect of air-cutting drying, and helping to reduce the energy consumption of subsequent drying. Attached Figure Description

[0016] Figure 1 This is a schematic diagram of the structure of this utility model;

[0017] Figure 2 yes Figure 1 A magnified view of part A in the middle. Detailed Implementation

[0018] The following is combined Figures 1-2 The technical solution of this utility model will be further illustrated through specific embodiments.

[0019] like Figure 1 The air-cutting and drying equipment shown is used for dewatering and drying the waterproof membrane carrier fabric 9. It includes: a frame 1, an air knife 2, a wet film 5, a first guide roller 11, and a second guide roller 12. The first guide roller 11 is horizontally arranged on the frame 1, and the second guide roller 12 is arranged on the frame 1 and located above and in front of the first guide roller 11. The waterproof membrane carrier fabric 9 is vertically conveyed from the bottom of the first guide roller 11 and passes through the second guide roller 12. The waterproof membrane carrier fabric 9 is pulled by a winding device or a traction device in front, so that the waterproof membrane carrier fabric 9 remains vertical and taut during the conveying process between the first guide roller 11 and the second guide roller 12.

[0020] The air knife 2 is vertically mounted on the frame 1 in a swingable manner, and the air outlet of the air knife 2 points to the front of the waterproof roll carrier fabric 9. In this embodiment, the frame 1 is provided with two pin seats 4 at the top and bottom to support the swing of the air knife 2, which supports the left and right swing of the air knife 2.

[0021] like Figure 2 As shown, a motor 13 is installed in the frame 1 below the air knife 2. A turntable 10 is installed on the rotating shaft at the top of the motor 13. A first pin 14 is eccentrically installed on the turntable 10. The motor 13 drives the first pin 14 to rotate eccentrically.

[0022] A second pin 16 is provided at the bottom of the air knife 2, and a connecting rod 15 is provided between the first pin 14 and the second pin 16. The eccentric rotation of the first pin 14 drives the reciprocating motion of the connecting rod 15, thereby realizing the left and right swing of the air knife 2.

[0023] like Figure 1 As shown, a compressed air supply pipe 3 is connected to the top of the air knife 2. The compressed air supply pipe 3 is connected to an air compressor, and compressed air is sent into the air knife 2 through the compressed air supply pipe 3. In this embodiment, the compressed air supply pipe 3 is a flexible hose to accommodate the left and right swinging of the air knife 2.

[0024] The wet membrane 5 is vertically mounted on the frame 1, located on both sides of the waterproof membrane carrier fabric 9 in the width direction. A water collection box 6 is installed below the wet membrane 5 within the frame 1 to collect water. By swinging the air knife 2 left and right, airflow is directed towards the vertically upward-conveyed surface of the waterproof membrane carrier fabric 9, causing the moisture on the fabric to form a water mist that flows along the width direction. As the water mist flows along the width direction, it comes into contact with the wet membrane 5 on both sides and is absorbed by the wet membrane 5. Then, it flows downwards with gravity into the water collection box 6, preventing the waterproof membrane carrier fabric from re-wetting due to the water mist and ensuring the effectiveness of the air-drying process.

[0025] In this embodiment, a drain valve 8 is provided on one side of the water receiving box 6, which can discharge water when opened. The water receiving box 6 is provided with a support 7 that extends upward and supports the wet film 5, which improves the stability of the wet film 5. Moreover, the water flow of the wet film 5 can flow downward through the support 7 into the water receiving box 6, avoiding splashing caused by dripping.

[0026] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
