Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of waterproof material production equipment, and in particular to a waterproof roll drying device. Background Technology
[0002] During the production of waterproof membrane rolls, after impregnation and other processes, a large amount of moisture remains on the surface, requiring drying before winding and subsequent use. Traditional drying methods often employ hot air ovens or electrically heated rollers. Hot air ovens are space-consuming and energy-intensive, and the hot air easily forms an air film on the membrane surface, affecting moisture evaporation efficiency. While simple heated roller drying offers high contact heat transfer efficiency, it struggles to quickly remove the large amount of moisture adhering to the membrane surface, leading to uneven drying or requiring a long drying path, thus also resulting in low efficiency. Utility Model Content
[0003] In view of the shortcomings of the existing technology, this utility model provides a waterproof membrane drying device to improve drying efficiency.
[0004] According to an embodiment of this utility model, a waterproof membrane drying device includes a guide roller group and a traction roller group. Two sets of drying roller mechanisms are provided between the guide roller group and the traction roller group, around which the waterproof membrane passes in sequence. The two sets of drying roller mechanisms respectively contact two sides of the waterproof membrane. Each set of drying roller mechanisms includes a hot air main roller, multiple water-absorbing auxiliary rollers, and a rotating power component that is drively connected to the hot air main roller. The hot air main roller generates a rotational motion opposite to the conveying direction. The multiple water-absorbing auxiliary rollers are evenly distributed circumferentially along the hot air main roller. Supports are rotatably connected to both ends of each water-absorbing auxiliary roller, and the supports are fixedly connected to the hot air main roller.
[0005] Preferably, the main hot air roller body is provided with a hot air cavity, one end of the main hot air roller body is connected to a hot air system, and the main hot air roller body is provided with multiple sets of hot air holes, which are distributed alternately with the water absorption auxiliary roller body.
[0006] More preferably, the absorbent roller body includes a free-rotating roller rotatably connected to the bracket and a flexible absorbent layer sleeved on the free-rotating roller.
[0007] More preferably, the free-rotating roller has a suction cavity inside, a suction hole on the free-rotating roller, and the suction cavity is connected to a suction system.
[0008] More preferably, a suction pipe is coaxially provided at one end of the hot air main roller body, the suction pipe is rotatably connected to the suction cavity through a branch pipe, and the suction pipe is connected to the suction system.
[0009] More preferably, the hot air main roller body is provided with a mounting groove parallel to its axis, and a portion of the water-absorbing auxiliary roller body is located in the mounting groove, so that the outer surface of the hot air main roller body is close to the waterproof membrane.
[0010] In a further preferred embodiment, the two sets of drying roller mechanisms are arranged inside the heat insulation cover, and the heat insulation cover has a feed inlet and a discharge outlet on both sides.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] It has high drying efficiency, combining hot air heating and evaporation with mechanical adsorption dehydration, which work synergistically to significantly shorten the drying time.
[0013] Energy saving and consumption reduction: The mechanical adsorption method directly removes liquid water, reducing the energy consumed by simply relying on thermal evaporation of large amounts of water. The design of the insulation cover further reduces heat loss.
[0014] The drying quality is good. The reverse-rotating hot air main roller and the simultaneous treatment of both sides of the roll material increase the fluid shear force and treatment intensity, making the drying more uniform and thorough. Attached Figure Description

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0021] This utility model provides an embodiment, such as Figure 1 As shown, a waterproof membrane drying device includes a guide roller group 1 and a traction roller group 2. Two sets of drying roller mechanisms 3 are provided between the guide roller group 1 and the traction roller group 2, around which the waterproof membrane passes in sequence. After being guided by the guide roller group 1, the wet waterproof membrane passes around the upper and lower sets of drying roller mechanisms 3 in an "S"-shaped meandering path. The two sets of drying roller mechanisms 3 respectively contact the two sides of the waterproof membrane.
[0022] like Figure 2 As shown, each set of drying roller mechanisms 3 includes a hot air main roller body 310, multiple water-absorbing auxiliary roller bodies 320, and a rotary power assembly that is drively connected to the hot air main roller body 310 (not shown in the figure). The hot air main roller body 310 is supported by a bearing seat and driven to rotate by the rotary power assembly. The hot air main roller body 310 generates a rotational motion opposite to the conveying direction. The multiple water-absorbing auxiliary roller bodies 320 are evenly distributed around the hot air main roller body 310. In this embodiment, four water-absorbing auxiliary roller bodies 320 are provided. The two ends of the water-absorbing auxiliary roller bodies 320 are movably connected to the brackets 330 through bearings, so that the water-absorbing auxiliary roller bodies 320 can rotate freely. The brackets 330 are fixedly connected to the hot air main roller body 310.
[0023] Specifically, such as Figure 3 , Figure 4 As shown, the hot air main roller body 310 is provided with a hot air cavity 311. One end of the hot air main roller body 310 is connected to an external hot air system through a rotary joint. The hot air main roller body 310 is provided with multiple sets of hot air holes 312 distributed along the circumference and axial direction. The hot air holes 312 and the water absorption auxiliary roller body 320 are distributed alternately.
[0024] The water-absorbing auxiliary roller body 320 includes a free-rotating roller 321 rotatably connected to the bracket 330 and a flexible water-absorbing layer 322 sleeved on the free-rotating roller 321. In this embodiment, the flexible water-absorbing layer 322 is a special water-absorbing fleece sleeve. The free-rotating roller 321 is provided with a suction cavity 323 and a suction hole 324. The suction cavity 323 is rotatably connected to an air extraction system.
[0025] Specifically, a suction pipe 325 is coaxially provided at one end of the hot air main roller 310. The suction pipe 325 is connected to a branch pipe 326. The branch pipe 326 is rotatably connected to the suction cavity 323 through a rotary joint. The suction pipe 325 is connected to the suction system through a rotary joint.
[0026] To enhance the effect of hot air, in a further embodiment, the hot air main roller 310 is provided with an installation groove 313 parallel to its axis, and part of the water-absorbing auxiliary roller 320 is located in the installation groove 313, so that the outer surface of the hot air main roller 310 is close to the waterproof membrane, and when the membrane passes by, more effective contact heating can be formed.
[0027] Specifically, the two sets of drying roller mechanisms 3 are arranged inside the heat insulation cover 4, and the heat insulation cover 4 has a feed inlet 401 and a discharge outlet 402 on both sides.
[0028] During operation, the main hot air roller 310 rotates in opposite directions, spraying hot air to heat and clean the roll material. Simultaneously, the revolving absorbent roller 320 continuously contacts the wet surface of the roll material, and the flexible absorbent layer 322 absorbs moisture. The absorbent roller 320 rotates to refresh its contact surface. The extraction system continuously draws away the absorbed moisture through the extraction holes 324, keeping the absorbent roller 320 dry and maintaining its absorbent capacity. This process occurs simultaneously on both the top and bottom surfaces, thus efficiently drying the roll material.
[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
