Description

Technical Field

[0001] This utility model relates to the field of waterproof membrane technology, and more specifically, to an integrated device for coating and cooling of waterproof membranes. Background Technology

[0002] Currently, in the production process of asphalt waterproof membranes, to prevent the membranes from sticking together during winding, a release liner is needed to cover the adhesive surfaces of the membranes. However, because the adhesive requires a certain temperature to melt, the waterproof membranes emerging from the immersion bath are generally at a high temperature. The release liner, typically made of PE or PET, has relatively low heat resistance. Covering the high-temperature waterproof membrane with the release liner can easily cause it to wrinkle or break due to heat, thus affecting its effectiveness. Therefore, a cooling process is necessary when laminating the release liner with the waterproof membrane.

[0003] Currently, most waterproof membrane production uses single-sided laminating equipment, such as the laminating device disclosed in CN201920282254.5, which includes an unwinding roller, a film-laying roller, an extrusion roller, a cooling roller, and a roller drive roller. The cooling roller consists of an outer cylinder and an inner cylinder, and is driven by the roller drive roller below. In the aforementioned laminating equipment, the cooling roller cools the laminated membrane, providing good cooling for the inner surface of the membrane. However, due to the poor thermal conductivity of asphalt, this method is insufficient for quickly and effectively cooling the outer surface of the membrane. This single cooling method reduces laminating efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an integrated cooling device for waterproof membrane coating, which can achieve uniform cooling by combining water cooling and air cooling methods, ensuring good coating effect and improving coating efficiency.

[0005] This utility model is achieved through the following technical solution: An integrated cooling and coating device for waterproof membrane includes a coating mechanism, a pre-cooling mechanism, and a main cooling mechanism arranged sequentially along the conveying direction of the waterproof membrane. Both the pre-cooling mechanism and the main cooling mechanism are located inside a cooling box, with an inlet and an outlet on each side wall of the cooling box. The pre-cooling mechanism includes a coolant box and a pre-cooling roller partially located inside the coolant box. A positioning roller is located above the pre-cooling roller, and the pre-cooling roller is tangent to the positioning roller. The main cooling mechanism includes at least two sets of guide rollers and cold air pipes located on the upper and lower sides of the guide rollers, with several air outlets on the cold air pipes.

[0006] Furthermore, the film coating mechanism includes an upper film-laying roller, a lower film-laying roller, an upper film-coating roller, and a lower film-coating roller. The upper film-laying roller is located to the upper left of the upper film-coating roller, and the lower film-laying roller is located to the lower left of the lower film-coating roller.

[0007] Furthermore, one end of the cold air duct passes through the side wall of the cooling box and is fixedly connected to the connecting flange, and the cold air duct is connected to the cooling air duct through the connecting flange.

[0008] Furthermore, guide vanes are provided on both sides of the air outlet.

[0009] Furthermore, an adjustment mechanism is provided between the precooling mechanism and the main cooling mechanism. The adjustment mechanism includes a support frame, an adjustment roller rotatably mounted on the support frame, and a power assembly connected to the bottom of the support frame.

[0010] Furthermore, the power assembly includes a mounting base, which contains a bidirectional threaded rod. Two sliding seats are symmetrically meshed on the bidirectional threaded rod. A connecting rod is rotatably connected to the top of each sliding seat. The upper ends of the two connecting rods are rotatably connected to the support frame.

[0011] Furthermore, the outer wall of the precooling roller is provided with a water-absorbing element.

[0012] Furthermore, the cooling box is equipped with guide rollers at its feed inlet.

[0013] The technical solution of this utility model has at least the following advantages and beneficial effects: In this invention, the rolled material, after being coated by the coating mechanism, is wound onto the surface of the positioning roller. The pre-cooling roller dips into the coolant in the coolant box and then evenly wets the surface of the rolled material, which can reduce the temperature of the rolled material on the positioning roller surface. The cold air blown out by the cold air pipe can reduce the temperature of the rolled material on the guide roller surface.

[0021] Example 1 Reference Figures 1-3 This embodiment provides an integrated coating and cooling device for waterproof membrane, including a coating mechanism 1, a pre-cooling mechanism, and a main cooling mechanism arranged sequentially along the conveying direction of the waterproof membrane. The pre-cooling mechanism and the main cooling mechanism are both located inside a cooling box 2. The cooling box 2 has an inlet 21 and an outlet 22 on its two side walls, respectively. The pre-cooling mechanism includes a coolant box 24 and a pre-cooling roller 25 partially located inside the coolant box 24. A positioning roller 26 is provided above the pre-cooling roller 25, and the pre-cooling roller 25 is tangent to the positioning roller 26. The main cooling mechanism includes at least two sets of guide rollers 33 and cold air pipes 34 located on the upper and lower sides of the guide rollers 33. The cold air pipes 34 are provided with a plurality of air outlets.

[0022] The film, after being coated by the coating mechanism 1, is wound onto the surface of the positioning roller 26. The pre-cooling roller 25 dips into the coolant in the coolant box 24 and evenly wets the surface of the film, which can reduce the temperature of the film on the roller surface of the positioning roller 26. The cold air blown out by the cold air pipe 34 can reduce the temperature of the film on the roller surface of the guide roller 33. The film is uniformly cooled by the combination of water cooling and air cooling. During the cooling process, the release film shrinks uniformly without wrinkling, ensuring a good coating effect and improving coating efficiency. Each roller is driven by a servo motor.

[0023] In a specific embodiment, the laminating mechanism 1 includes an upper film-laying roller 11, a lower film-laying roller 12, an upper film-laying roller 13, and a lower film-laying roller 14. The upper film-laying roller 11 is located to the upper left of the upper film-laying roller 13, and the lower film-laying roller 12 is located to the lower left of the lower film-laying roller 14. This laminating mechanism 1 can achieve double-sided lamination of roll materials, thus accelerating the laminating efficiency.

[0024] In a specific embodiment, one end of the cold air duct 34 passes through the side wall of the cooling box 2 and is fixedly connected to the connecting flange. The cold air duct 34 is connected to the cooling air duct through the connecting flange.

[0025] In a specific implementation, guide vanes 35 are provided on both sides of the air outlet. The guide vanes 35 can concentrate the cold air and accelerate the cooling speed of the roll material.

[0026] In a specific embodiment, an adjustment mechanism is provided between the precooling mechanism and the main cooling mechanism. The adjustment mechanism includes a support frame 28, an adjustment roller 27 rotatably mounted on the support frame 28, and a power component connected to the bottom of the support frame 28.

[0027] In a specific embodiment, the power assembly includes a mounting base 29, within which a bidirectional threaded rod 30 is provided. Two sliding seats 31 are symmetrically meshed on the bidirectional threaded rod 30. Connecting rods 32 are rotatably connected to the top of each sliding seat 31. The upper ends of the two connecting rods 32 are rotatably connected to the support frame 28. One end of the bidirectional threaded rod 30 extends out of the cooling box 2 and is connected to a motor. The height of the adjusting roller 37 can be adjusted via an adjusting mechanism to extend the cooling path of the roll material, further improving the cooling speed. Simultaneously, the roll material can be tensioned to prevent deviation.

[0028] In a specific embodiment, the outer wall of the precooling roller 25 is provided with a water-absorbing element. The water-absorbing element can be a water-absorbing sponge, which can absorb more coolant, thereby allowing the coolant to better wet the roll material.

[0029] In a specific embodiment, a guide roller 23 is provided at the feed inlet of the cooling box 2.

[0030] During operation, the upper unwinding roller 11 and the lower unwinding roller 12 unwind the release film. The unwound roll and the release film are then coated by the combined pressure of the upper coating roller 13 and the lower coating roller 14. After coating, the roll passes through the guide roller 23 at the inlet 21 of the cooling box 2 and is wound onto the surface of the positioning roller 26. The pre-cooling roller 25 rotates and continuously dips into the coolant in the coolant box 24, then uses the coolant to wet the surface of the roll, achieving initial cooling of the roll. After initial cooling, the roll passes through the adjusting roller 27 and is wound onto the surface of the guide roller 33. The cold air blown out by the cold air pipe 34 is guided by the guide plate 35 to blow onto the surface of the roll, reducing the temperature of the roll on the roller surface of the guide roller 33, achieving secondary cooling of the roll. Then, the roll is discharged through the outlet 22 of the cooling box 2, completing the coating of the roll.

[0031] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
