Technical Field

[0001] This utility model provides a drying device, and particularly relates to a continuous drying device for the production of waterproof membrane rolls. Background Technology

[0002] In the production process of waterproof membrane, the drying device is a key piece of equipment used to dry the produced waterproof membrane. Its function is to remove moisture from the waterproof membrane and ensure that the physical and waterproof properties of the waterproof membrane meet the requirements for use. Since waterproof membranes are mostly stored and transported in a rolled-up state after production, the drying device needs to be adapted to the rolled-up waterproof membrane to achieve efficient drying operations.

[0003] Existing drying equipment for rolled waterproof membranes typically requires the rolled membrane to be fully unrolled manually or with simple auxiliary devices before being transported to the drying unit for drying. However, this structure has significant shortcomings: firstly, the unrolling process is cumbersome, consuming considerable manpower and time, thus reducing production efficiency; secondly, improper operation during the unrolling process can easily lead to wrinkles and damage to the waterproof membrane, affecting drying quality; furthermore, the integration between the limiting and guiding structure and the heating structure of existing drying equipment is poor, making it difficult to achieve continuous, stable, and efficient drying of rolled waterproof membranes, failing to meet the dual requirements of drying efficiency and quality in the production process. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a continuous drying device for waterproof membrane production, comprising an outer frame 1, a roll-up waterproof membrane 2 to be dried, two limiting rollers 3, and a heating device 4; the outer frame 1 has a clamping structure 5 for clamping the winding shaft of the roll-up waterproof membrane 2, so that the roll-up waterproof membrane 2 is rotatably mounted on the outer frame 1; the two limiting rollers 3 are disposed on the outer frame 1 and located below the exit side of the roll-up waterproof membrane 2, for limiting and guiding the waterproof membrane 2 as it unfolds from the roll-up waterproof membrane 2; the heating device 4 is disposed downstream of the two limiting rollers 3, and the heating device 4 includes two heating elements 6 disposed vertically to heat the passing waterproof membrane 2 from both above and below; the lower heating element 6 has multiple rows of parallel heating copper tubes inside, and the heating copper tubes are connected to an external heat exchange component 7 through pipelines.

[0006] Furthermore, the mounting outer frame 1 includes two oppositely arranged arc-shaped side plates, which are fixedly connected by several connecting ribs. The clamping structure 5 is a clamping hole opened on the two arc-shaped side plates and adapted to the winding shaft.

[0007] Furthermore, the lower part of the arc-shaped side plate is also provided with a support seat for supporting the two limiting rollers 3, and the two ends of the limiting rollers 3 are respectively rotatably connected to the support seats on the two arc-shaped side plates.

[0008] Furthermore, the winding shaft of the roll-up waterproof membrane 2 is cylindrical, and both ends of the winding shaft are rotatably engaged in the clamping structure 5 of the mounting outer frame 1.

[0009] Furthermore, the two limiting rollers 3 are arranged parallel to each other, and the axes of the two limiting rollers 3 are parallel to the axis of the winding shaft of the winding waterproof membrane 2.

[0010] Furthermore, the heating material 6 below is a cuboid structure with an internal accommodating cavity, and the heating copper tube is coiled in a serpentine manner within the accommodating cavity.

[0011] Furthermore, the heat exchange component 7 is a rectangular box structure, and the heat exchange component 7 is connected to the inlet and outlet of the heating copper tube through a curved pipe.

[0012] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages compared with the prior art:

[0013] This utility model directly clamps the winding shaft of the rolled waterproof membrane 2 through the clamping structure 5 of the mounting outer frame 1, so that the rolled waterproof membrane 2 can be rotatably installed on the mounting outer frame 1 without having to unroll the rolled waterproof membrane in advance, which greatly simplifies the preparation process before drying, saves manpower and time, and effectively improves production efficiency.

[0014] Two limiting rollers 3 are used to limit and guide the waterproof membrane 2 as it unfolds from the rolled-up waterproof membrane 2, ensuring the stability of the waterproof membrane 2 during the conveying process, avoiding wrinkles and damage caused by conveying deviation, and ensuring the drying quality.

[0015] The heating device 4 uses two heating elements 6 arranged vertically to heat the passing waterproof membrane 2 simultaneously from top to bottom.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] like Figures 1-4 A continuous drying device for producing waterproof membrane includes an outer frame 1, a roll-up waterproof membrane to be dried 2, two limiting rollers 3, and a heating device 4.

[0027] The outer frame 1 is used to facilitate the quick installation of the roll-up waterproof membrane 2. The outer frame 1 includes two opposing arc-shaped side plates, which are fixedly connected by several connecting ribs to ensure structural strength. The outer frame 1 has a clamping structure 5 for clamping the winding shaft of the roll-up waterproof membrane 2. The clamping structure 5 consists of clamping holes on the two arc-shaped side plates that are adapted to the winding shaft. The winding shaft of the roll-up waterproof membrane 2 is cylindrical, and both ends of the winding shaft are rotatably inserted into the clamping structure 5 (clamping holes) of the outer frame 1, so that the roll-up waterproof membrane 2 can be rotatably installed on the outer frame 1 without pre-unrolling the membrane, thus simplifying the process.

[0028] Two limiting rollers 3 are installed on the outer frame 1 and located below the exit side of the rolled waterproof membrane 2. They are used to limit and guide the waterproof membrane 2 as it is unrolled from the rolled waterproof membrane 2. The lower part of the arc-shaped side plate is provided with a support seat for supporting the two limiting rollers 3. The two ends of the limiting rollers 3 are rotatably connected to the support seats on the two arc-shaped side plates respectively. The two limiting rollers 3 are arranged parallel to each other, and the axes of the two limiting rollers 3 are parallel to the axis of the winding shaft of the rolled waterproof membrane 2. This ensures that after the waterproof membrane 2 is unrolled from the rolled waterproof membrane 2, it is conveyed to the subsequent heating device 4 along a stable path.

[0029] The heating device 4 is located downstream of the two limiting rollers 3 and is used to dry the passing waterproof membrane 2. The heating device 4 includes two heating elements 6 arranged vertically to heat the passing waterproof membrane 2 from both the top and bottom (to ensure uniform and comprehensive heating). The lower heating element 6 is a cuboid structure with an internal cavity, and inside it are multiple rows of parallel heating copper tubes arranged in a serpentine pattern within the cavity (to increase the heating area). The heating copper tubes are connected to an external heat exchange component 7 through pipes. The heat exchange component 7 is a cuboid box structure that is connected to the inlet and outlet of the heating copper tubes through curved pipes, providing a heat medium such as hot water or heat transfer oil to the heating copper tubes to ensure the heating effect of the heating element 6.

[0030] The working process of this embodiment is as follows: In use, the two ends of the winding shaft of the rolled waterproof membrane 2 are inserted into the clamping structure 5 (clamping hole) of the mounting frame 1, so that the rolled waterproof membrane 2 is rotatably mounted on the mounting frame 1; then, the free end of the rolled waterproof membrane 2 is pulled to unwind it from the wound state, and it passes through the limiting guide of two limiting rollers 3 in sequence; then, the unwound waterproof membrane 2 enters between the two heating elements 6 of the heating device 4, and is dried by the synchronous heating of the upper and lower heating elements 6; during the drying process, the rolled waterproof membrane 2 continues to rotate and unwind, and the waterproof membrane 2 continuously passes through the heating device 4 to achieve continuous drying operation; at the same time, the heat exchange component 7 continuously provides heat medium to the heating copper tube in the lower heating element 6 through the pipeline to ensure the continuity and stability of heating.

[0031] During the use of this device, it needs to be used in conjunction with the existing unwinding drive mechanism to smoothly rotate and unwind the rolled waterproof membrane. This unwinding drive mechanism can be a combination of a servo motor and a reduction gear set. The output shaft of the servo motor is connected to one end of the winding shaft of the rolled waterproof membrane via a coupling to achieve precise speed adjustment. Simultaneously, a membrane traction mechanism, similar to existing technology, needs to be installed downstream of the heating device. This traction mechanism uses upper and lower counter-pressing rubber traction rollers. The drive motor rotates the rubber traction rollers to continuously pull the waterproof membrane forward. The surface of the rubber traction rollers needs to be treated with anti-slip material to prevent the membrane from slipping. To achieve precise control of the heating temperature, temperature sensors need to be installed near the two heating elements of the heating device. The temperature sensors are electrically connected to the existing PLC control cabinet, which is then electrically connected to the heat transfer pump of the heat exchange component. The temperature sensors detect the temperature of the heating area in real time and feed it back to the PLC control cabinet, which then adjusts the output of the heat transfer pump. The output power controls the flow rate of the heating medium inside the heating copper tube, thereby stabilizing the heating temperature within a preset range. The outer frame can be welded from Q235 low-carbon steel, with its arc-shaped side plate thickness set at 8-12mm to ensure structural strength. The limit roller is made of 45# steel with chrome plating to improve wear resistance. The outer shell of the heating element is made of 304 stainless steel to provide good high-temperature resistance and corrosion resistance. The heat exchange components are made of Q345R pressure vessel steel to meet pressure requirements. The heating copper tube is made of T2 copper with a diameter of 10-15mm. The pipeline connecting the heating copper tube and the heat exchange components uses polyurethane insulation to reduce heat loss. In addition, a cooling fan, as used in the prior art, can be installed between the heating device and the traction mechanism to quickly cool the dried waterproof membrane. Finally, the dried and cooled waterproof membrane is rewound into a cylinder by a winding machine, with the winding speed of the winding machine synchronized with the traction speed of the traction mechanism to ensure winding quality.

[0032] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
