Detailed Implementation

[0018] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0020] When producing reinforced or laminated waterproof membranes, a separate unwinding device is typically required. To achieve continuous production, a storage rack is usually added. However, when the unwinding material is mesh or non-woven fabric, the storage process can lead to uncontrolled tension in the product, which in turn affects the material's performance in the lamination stage and the final product quality.

[0021] This application provides a waterproof membrane production device that achieves stable bonding during material movement based on dynamic tension control, effectively solving the coordination problem between unwinding tension control and continuous production.

[0022] The following is in conjunction with the accompanying drawings in the instruction manual. Figs. 1-3 A detailed explanation and description of the waterproof membrane production equipment is provided.

[0023] This application provides a waterproof membrane production apparatus, which includes: a support frame 1; a self-driven support assembly disposed on the support frame 1, including a first self-driven support component 21 and a second self-driven support component 22, the first self-driven support component 21 and the second self-driven support component 22 respectively supporting a first fabric roll and a second fabric roll; a heating and pressing mechanism disposed on the support frame 1, located between the first self-driven support component 21 and the second self-driven support component 22, for pulling, heating and pressing the fabric output from the first and second fabric rolls; an offset sensing component for sensing the offset information of the composite fabric after the first and second fabric rolls are pressed together, and sending the offset information to the self-driven support assembly to adjust its own position; and a tensioning component 3 disposed on the support frame 1 for tensioning the composite fabric.

[0024] Specifically, the waterproof membrane production device includes: a support frame 1, a self-driven support assembly, a heating and pressing mechanism, an offset sensing component, and a tensioning component 3. The self-driven support assembly is located on the support frame 1 and includes a first self-driven support component 21 and a second self-driven support component 22. The first and second self-driven support components 21 and 22 respectively support the first and second fabric rolls. The heating and pressing mechanism is located on the support frame 1, between the first and second self-driven support components 21 and 22, and is used to pull, heat, and press the fabric output from the first and second fabric rolls. This integrates processes that might otherwise need to be completed in sections at different workstations, improving production efficiency and ensuring the uniformity of the composite quality. The offset sensing component... The device senses the offset information of the laminated fabric after pressing and sends the offset information to the self-driven support components so that the first self-driven support component 21 and the second self-driven support component 22 adjust their positions, thereby adjusting the positions of the first and second fabric rolls and correcting the deviation at the source. This greatly reduces quality defects such as wrinkling and uneven lamination caused by fabric deviation, while reducing the need for production interruptions and ensuring continuous, stable, and high-speed production. The two independent and automatically adjustable first self-driven support components 21 and 22 allow the equipment to flexibly adapt to fabric rolls of different specifications and materials. The tensioning component 3 is set on the support frame 1 to tension the laminated fabric, providing the necessary and stable tension for the laminated fabric.

[0025] In some optional embodiments, the first self-driven support component 21 includes a first fixing frame 211 and a first power output component 212. The first fixing frame 211 supports the first fabric roll, and the first power output component 212 is disposed on the first fixing frame 211 and drives the first fixing frame 211 to move along a preset path. Optionally, the second self-driven support component 22 includes a second fixing frame 221 and a second power output component 222. The second fixing frame 221 supports the second fabric roll, and the second power output component 222 is disposed on the second fixing frame 221 and drives the second fixing frame 221 to move along a preset path.

[0026] Specifically, the offset sensing component is electrically connected to the first self-driven support component 21. The offset sensing component senses the offset information of the composite fabric after pressing and generates a movement command, which is then sent to the first self-driven support component 21. Upon receiving the movement command, the first self-driven support component 21 moves the first fixing frame 211, thereby adjusting the position of the first fabric roll. The offset sensing component is also electrically connected to the second self-driven support component 22. The offset sensing component senses the offset information of the composite fabric after pressing and generates a movement command, which is then sent to the second self-driven support component 22. Upon receiving the movement command, the second self-driven support component 22 moves the second fixing frame 221, thereby adjusting the position of the second fabric roll. The offset sensing component and the self-driven support assembly form a closed-loop control system, which can detect the deviation of the composite fabric in real time and automatically adjust the support position of the fabric roll, correcting the deviation at its source. This greatly reduces quality defects such as wrinkling and uneven bonding caused by fabric misalignment, while reducing the need for production interruptions and ensuring continuous, stable, and high-speed production. In addition, the use of two independent and automatically adjustable first self-driving support components 21 and second self-driving support components 22 enables the equipment to flexibly adapt to fabric rolls of different specifications and materials.

[0027] In some optional embodiments, the first self-driving support component 21 further includes a first roll diameter monitoring component 23, which is disposed on the first fixing frame 211.

[0028] Specifically, the first roll diameter monitoring component 23 is used to monitor the diameter of the first roll of fabric, to help determine the remaining fabric in the first roll of fabric, and sends the information to the controller, which then issues a command to the alarm to remind the staff that the remaining fabric in the first roll of fabric is about to be consumed.

[0029] In some optional embodiments, the second self-driving support component 22 further includes a second roll diameter monitoring component 24, which is disposed on the second fixing frame 221.

[0030] Specifically, the second roll diameter monitoring component 24 is used to monitor the diameter of the first roll, to help determine the remaining fabric in the second roll, and sends the information to the controller, which then issues a command to the alarm to remind the staff that the remaining fabric in the first roll is about to be consumed.

[0031] In some alternative embodiments, the first power output component 212 is an electric slide rail.

[0032] Specifically, the electric slide rail includes a bracket, a lead screw, a lead screw nut, and a motor. The lead screw is fixed by the bracket, and the lead screw nut is threadedly connected to the lead screw. The motor is located on the bracket and drives the lead screw to rotate, thereby causing the lead screw nut to move along the length of the lead screw. A first fixing frame 211 is located on the lead screw nut, and the lead screw nut moves along the length of the lead screw, causing the first fixing frame 211 to move. An offset sensing component is used to sense the offset information of the composite fabric after pressing and generate a movement command, which is then sent to the motor. Upon receiving the movement command, the motor drives the lead screw to rotate, and the lead screw thread moves along the lead screw, thereby adjusting the position of the first fixing frame 211, and thus adjusting the position of the first fabric roll.

[0033] In some optional embodiments, the first dynamic output component includes a first motor, a first gearbox, a first drive wheel, and a first driven wheel. The first motor drives the first drive wheel to rotate through the first gearbox, and the first driven wheel is used to support the first fixed frame 211 and move with the first drive wheel.

[0034] Specifically, two first driving wheels are provided, each fixed to a first fixed frame 211 by a fixing member. The two first driving wheels are located at one end of the length direction of the first fixed frame 211 and are positioned opposite each other in the width direction of the first fixed frame 211. A first motor and a first gearbox are located on the first fixed frame 211, and the first motor is connected to the two first driving wheels via two output shafts of the first gearbox. Two first driven wheels are located at the other end of the length direction of the first fixed frame 211 and are positioned opposite each other in the width direction of the first fixed frame 211. The two first driven wheels are also fixed to the first fixed frame 211 by fixing members.

[0035] In some alternative embodiments, the second power output component 222 is an electric slide rail.

[0036] Specifically, the electric slide rail includes a bracket, a lead screw, a lead screw nut, and a motor. The lead screw is fixed by the bracket, and the lead screw nut is threadedly connected to the lead screw. The motor is located on the bracket and drives the lead screw to rotate, thereby causing the lead screw nut to move along the length of the lead screw. The second fixing frame 221 is located on the lead screw nut, and the lead screw nut moves along the length of the lead screw, causing the second fixing frame 221 to move. The offset sensing component is used to sense the offset information of the composite fabric after pressing and generate a movement command, which is then sent to the motor. Upon receiving the movement command, the motor drives the lead screw to rotate, and the lead screw thread moves along the lead screw, thereby adjusting the position of the second fixing frame 221, and thus adjusting the position of the second fabric roll.

[0037] In some optional embodiments, the second dynamic output component includes a second motor, a second gearbox, a second driving wheel, and a second driven wheel. The second motor drives the second driving wheel to rotate through the second gearbox, and the second driven wheel is used to support the second fixed frame 221 and move with the second driving wheel.

[0038] Specifically, two second driving wheels are provided, each fixed to a second fixed frame 221 by a fixing member. The two driving wheels are located at one end of the length direction of the second fixed frame 221 and are positioned opposite each other in the width direction of the second fixed frame 221. A second motor is located on the second fixed frame 221, and a first gearbox is also located on the second fixed frame 221. The second motor is connected to the two driving wheels via two output shafts of the second gearbox. Two second driven wheels are located at the other end of the length direction of the second fixed frame 221 and are positioned opposite each other in the width direction of the second fixed frame 221. The two second driven wheels are also fixed to the second fixed frame 221 by fixing members.

[0039] In some optional embodiments, the heating and pressing mechanism includes a traction component 41, a heating component 42, and a pressing component 43. The traction component 41, the heating component 42, and the pressing component 43 are arranged sequentially from high to low in the support frame 1. The fabric output from the first fabric roll and the second fabric roll passes through the traction component 41, the heating component 42, and the pressing component 43 in sequence.

[0040] Specifically, the traction component 41, heating component 42, and pressing component 43 are arranged sequentially from high to low on the support frame 1. Under its own gravity, the fabric tends to droop naturally from the traction component 41 to the pressing component 43, which reduces the need for active traction force and makes material transfer smoother and more stable. Gravity helps the fabric adhere tightly to each roller and heating surface, avoiding problems such as jamming, wrinkling, or uneven internal stress caused by fabric looseness or drifting. The traction component 41 drives the first and second fabric rolls to move, ensuring that the two rolls of fabric enter the lamination zone at a stable, synchronized speed and in the correct relative position, which is the foundation for subsequent high-quality lamination. The heating component is used to heat the first and second fabric rolls, uniformly heating the positioned first and second fabric rolls to bring the hot melt adhesive of the asphalt coating of the asphalt waterproof membrane to the optimal melting and activation state. The pressing component 43 is used to further press the composite fabric, making the composite fabric adhere more firmly. By integrating the traction component 41, heating component 42, and pressing component 43 onto a continuous, sloping path, the transmission distance and time of the fabric between each process are shortened, achieving a near-seamless process connection.

[0041] In some alternative embodiments, the traction assembly 41 includes a first traction component 411 and a second traction component 412. The first traction component 411 is disposed near the first self-driven support component 21 to traction the first fabric roll, and the second traction component 412 is disposed near the second self-driven support component 22 to traction the second fabric roll.

[0042] Specifically, the first traction component 411 includes a driving roller and a driven roller. The driving roller is driven to rotate by a motor, which is electrically connected to the controller of the offset sensing component. The photoelectric sensor 51 of the offset sensing component is used to sense offset information and send the offset information to the controller. The controller receives the offset information and sends a command to the motor, which adjusts the speed of the driving roller to avoid offset. The driving roller and driven roller of the first traction component 411 are used to clamp the first fabric and drive the first fabric to unwind and move. After the first roll of fabric is released, it is immediately pulled by the adjacent first traction component 411. Before the first fabric enters the composite zone, the first traction component 411 establishes a stable and uniform tension for it.

[0043] Optionally, the traction assembly 41 further includes a first infrared monitoring component 61, which is used to monitor the remaining fabric in the first fabric roll. The first infrared monitoring component 61 monitors the remaining fabric in the first fabric roll in real time. The first infrared monitoring component 61 is electrically connected to the controller. When the remaining fabric in the first fabric roll is insufficient, the controller receives the information from the first infrared monitoring component 61 and sends an alarm to the alarm device to remind the staff to pay attention.

[0044] Optionally, a second infrared monitoring component 62 is also included. The second infrared monitoring component 62 is used to monitor the remaining fabric in the second fabric roll. The second infrared monitoring component 62 monitors the remaining fabric in the first fabric roll in real time. The second infrared monitoring component 62 is electrically connected to the controller. When the remaining fabric in the second fabric roll is insufficient, the controller receives information from the second infrared monitoring component 62 and sends an alarm to alert the staff. Optionally, the second infrared monitoring component 62 is an infrared monitoring sensor. The first infrared monitoring component 61 is also an infrared monitoring sensor.

[0045] When there is insufficient remaining fabric in the first or second roll of fabric, start the hoisting device 7 to remove the support shaft of the first or second roll of fabric and replace it with a new first or second roll of fabric.

[0046] The second traction component 412 includes a drive roller and a driven roller. The drive roller is driven by a motor, which is electrically connected to the controller of the offset sensing component. The photoelectric sensor 51 of the offset sensing component is used to sense offset information and send the offset information to the controller. The controller receives the offset information and sends a command to the motor, which adjusts the speed of the drive roller to avoid offset. The drive roller and driven roller of the second traction component 412 are used to clamp the second fabric and drive the second fabric to unwind and move. After the second fabric roll is released, it is immediately pulled by the adjacent second traction component 412. Before the first fabric enters the composite zone, the first traction component 411 establishes a stable and uniform tension for it.

[0047] Furthermore, although the paths of the first traction component 411 and the second traction component 412 are independent, they maintain strict synchronous operation under the control of the controller. This ensures that the first and second fabric rolls are fed into the subsequent lamination section at exactly the same linear speed, which is a prerequisite for achieving high-quality lamination and effectively avoids fabric wrinkling, stretching, or relative slippage caused by speed differences. Since the first and second fabric rolls are independently guided and stabilized in the initial stage, the probability of them interfering with each other and deviating from their respective paths is greatly reduced.

[0048] In some alternative embodiments, the traction assembly 41 further includes a flattening component located between the first traction component 411 and the second traction component 412. The flattening component includes a first flattening roller 413 and a second flattening roller 414, with the first flattening roller 413 disposed close to the first traction component 411 and the second flattening roller 414 disposed close to the second traction component 412.

[0049] Specifically, the first flattening roller 413 is adjacent to its respective first traction component 411, and the second flattening roller 414 is adjacent to its respective second traction component 412. This allows for precise correction of any curling or wrinkling that may exist in the fabric at the last moment before it enters the lamination area after traction is completed. The first flattening roller 413 and the second flattening roller 414 are typically designed as rollers with a certain degree of concave and convex arc surfaces. When they rotate, they apply an extended tension to the edges of the fabric in the width direction, effectively neutralizing the shrinkage stress inside the fabric, stretching the fabric, and restoring it to a flat state. A flat fabric will not experience accidental lateral slippage during lamination, better maintaining the preset alignment, resulting in a final laminated fabric with neat edges and a symmetrical structure.

[0050] In some alternative embodiments, the heating element 42 is an ultrasonic heater.

[0051] Specifically, the ultrasonic heater allows ultrasonic energy to act simultaneously on the bonding interface of the composite fabric from both sides, achieving energy superposition. This instantly causes the molecules inside the material to vibrate and rub at high frequency, thus achieving rapid and uniform heating in a very short time. Ultrasonic heating is volumetric heating, with energy acting directly on the inside of the material. This inside-out heating method ensures that the asphalt bonding layer or polymer film can be fully and uniformly melted and activated, providing the best bonding state for subsequent pressing, thereby improving the composite peel strength.

[0052] The ultrasonic heater creates a uniform energy field that can cover the entire width of the fabric, avoiding the problem of local overheating or underheating that may occur due to uneven heat conduction in unilateral heating, and ensuring consistent heating quality at every point of the composite interface.

[0053] Ultrasonic heating allows for instantaneous start and stop, precise power adjustment, and direct heat concentration on the interface layer requiring melting, rather than dissipating into the surrounding environment or non-critical areas of the material. This results in extremely high thermal efficiency, greater energy savings, and prevents material aging or deformation due to prolonged heating. Furthermore, ultrasonic heating avoids direct contact with the high-temperature molten asphalt material, fundamentally eliminating problems such as downtime for cleaning and product damage caused by material adhesion to the heating rollers, significantly improving production continuity and stability.

[0054] In some alternative embodiments, the pressing assembly 43 includes a sliding member 431, an extrusion member 432, and a cooling roller 433. The sliding member 431 extends in the height direction of the support frame 1. The extrusion member 432 and the cooling roller 433 adjust their positions by adjusting the area fixed to the sliding member 431. The extrusion member 432 applies extrusion force toward the cooling roller 433. The composite fabric passes between the extrusion member 432 and the cooling roller 433.

[0055] Specifically, the sliding component 431 includes four electric slide rails, two of which are located at both ends of the ultrasonic heater along its length and one side along its width, and the other two are located at both ends of the ultrasonic heater along its length and the other side along its width. Each electric slide rail extends along the height direction of the support frame 1. Each electric slide rail is fixed to the support frame 1, or two electric slide rails are fixed at both ends of the ultrasonic heater along its length and one side along its width, or two electric slide rails are fixed at both ends of the ultrasonic heater along its length and the other side along its width. The pressing component 432 is fixed to the electric slide rails located at both ends of the ultrasonic heater along its length, and the cooling roller 433 is fixed to the electric slide rails located at both ends of the ultrasonic heater along its length, or the fixing positions of the pressing component 432 and the cooling roller 433 are interchanged.

[0056] After the composite fabric is bonded under pressure in a hot-melt state, it immediately comes into large-area contact with the cooling roller 433, which is filled with cooling medium. The heat is quickly carried away, causing the molten asphalt layer or polymer layer to solidify and set instantly. This instant solidification effectively prevents the product from deforming or shrinking due to its own residual heat after leaving the pressing point, or the bonding interface from separating due to tension. This ensures the stability of the composite dimensions and the integrity of the bonding effect.

[0057] In some optional embodiments, the offset sensing component includes a photoelectric sensor 51 and a controller. The photoelectric sensor 51 is disposed on the support frame 1, and the controller is connected to the photoelectric sensor 51 and the self-driving support assembly, respectively.

[0058] Specifically, the photoelectric sensor 51 can detect minute positional changes at the edge of the composite fabric in a non-contact, real-time, and high-frequency manner. Its detection accuracy far exceeds that of the human eye. Once an offset exceeding the tolerance is detected, the signal is instantly sent to the controller, achieving a millisecond-level feedback speed. This provides valuable time for subsequent timely correction and prevents the continuous accumulation of deviations. The controller, as the brain of the entire correction system, receives the sensor signals, performs calculations through internal algorithms, and immediately issues precise adjustment commands to the self-driven support components.

[0059] In some optional embodiments, the tensioning component 3 further includes a third fixing frame 31, a third flattening roller 32, a tension adjusting component 33, and a first tensioning roller 34. The third fixing frame 31 includes a first support end 311 and a second support end 312. The second support end 312 is rotatably connected to the third fixing frame 31. The third flattening roller 32 is disposed on the first support end 311, and the first tensioning roller 34 is disposed on the second support end 312. One end of the tension adjusting component 33 is disposed on the third fixing frame 31, and the other end pulls the second support end 312, adjusting the tilt angle of the second support end 312 by adjusting its own force and length.

[0060] Specifically, the third flattening roller 32 is fixed to the first support end 311, and the first tensioning roller 34 is disposed on the movable second support end 312. When the tension adjusting component 33 is activated, it not only adjusts the overall tension by changing the position of the first tensioning roller 34, but also changes the relative position and angle between the third flattening roller 32 and the first tensioning roller 34 due to leverage, thereby simultaneously fine-tuning the flattening effect. By changing the tilt angle of the second support end 312, this mechanism can significantly change the wrap angle and path length of the fabric, thereby achieving wide-range and precise tension control. The tension adjusting component 33 can be selected as a cylinder, and by controlling its force and length, the position of the second support end 312 can be precisely and steplessly set, thereby providing the production line with extremely stable and precisely settable tension, which is crucial for ensuring product dimensional stability and composite quality.

[0061] Furthermore, the tensioning component 3 also includes a second tensioning roller 35, which is located in the third fixed frame 31 and between the first support end 311 and the second support end 312. After the composite fabric is output from the heating component 42, it enters the tensioning component 3 after passing through multiple reversing rollers 9, which are located in the support frame 1.

[0062] In some optional embodiments, a main traction component 8 is also included, which is used to receive the composite fabric output by the tensioning component 3. The main traction component 8 includes a fourth fixed frame 81, a third traction roller 82, an auxiliary traction roller 83, and a driven roller 84. The third traction roller 82 is located at the top of the fourth fixed frame 81, and the auxiliary traction roller 83 and the driven roller 84 are arranged side by side at the bottom of the fourth fixed frame 81.

[0063] Specifically, after the composite fabric is output from the tensioning component 3, it passes through the driven roller 84, the third traction roller 82 and the auxiliary traction roller 83 in sequence before being output.
