Description

Technical Field

[0001] The present invention relates to the technical field of waterproof coiled material processing, in particular to a production process of asphalt-based waterproof coiled material. Background Art

[0002] The production process of asphalt-based waterproofing membranes presents a series of issues that impact product quality and production efficiency. First, due to the properties of asphalt, hardened asphalt tends to settle to the bottom of the asphalt tank. This not only wastes asphalt raw material but also leads to uneven asphalt composition during subsequent production, which in turn affects the performance of the waterproofing membrane. Second, the base material needs to be stirred while immersed in the asphalt tank to ensure that the base is fully bonded to the asphalt. However, existing stirring methods have several shortcomings. The base material will wrinkle when immersed in the asphalt tank, making it impossible to achieve uniform and effective stirring, resulting in poor bonding between the base and the asphalt, affecting the quality and stability of the membrane. In addition, due to intermittent asphalt supply, uneven asphalt distribution within the tank, or failures in certain links of the production process, the base material may experience gaps in the asphalt raw material during production. These gaps can result in the base material being partially impregnated with asphalt, seriously affecting the waterproofing performance and overall quality of the waterproofing membrane.

[0003] If the existing asphalt waterproofing membrane production process wants to solve the above problems, it is necessary to set up targeted mechanisms for each problem. When producing asphalt-based membranes, the asphalt pool needs to maintain high temperature for a long time, and as the use time increases, asphalt enters the interior of these mechanisms, which will have a great impact on the service life of the mechanisms.

[0004] In view of this, we propose a production process of asphalt-based waterproof membrane to improve the shortcomings of the existing technology. Summary of the Invention

[0005] The purpose of the present invention is to provide a production process for an asphalt-based waterproofing membrane to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the present invention provides a process for producing an asphalt-based waterproofing membrane, comprising the following steps:

[0007] S1. Start the tire base transfer mechanism to allow the tire base to pass through the storage tank containing asphalt, so that the inside and surface of the tire base are covered with asphalt;

[0008] S2. Start the stirring mechanism to stir the asphalt in the reservoir so that the asphalt is in full contact with the tire base, and at the same time stir the asphalt deposited at the bottom of the reservoir to the upper part;

[0009] S3. While the stirring mechanism is stirring the asphalt, the stirring mechanism drives the regulating mechanism to adjust the tightness of the tire base material so that the asphalt can enter the structure of the tire base material. At the same time, the regulating mechanism can smooth out wrinkles and bubbles on the surface of the tire base material.

[0010] S4. The base material is driven by the transfer mechanism to pass through the bottom of the forming mechanism. The excess asphalt wrapped on the surface of the base material is wiped off by the forming mechanism to ensure that the obtained asphalt-based waterproof membrane meets the actual needs. When the adjusting mechanism pulls the base material, the base drives the forming mechanism to move, and the excess asphalt is moved to the part of the base material where there is a gap in the asphalt raw material;

[0011] The transfer mechanism includes a pair of transfer rollers disposed on opposite sides of the reservoir, the two transfer rollers driving the tire base material through the asphalt pool in the reservoir, the stirring mechanism includes at least a stirring assembly, the regulating mechanism includes at least a regulating assembly disposed on one side of the stirring assembly, and the forming mechanism includes a forming assembly;

[0012] The stirring assembly is used to stir the asphalt in the reservoir so that the asphalt and the tire base material are fully mixed. The stirring assembly can stir the asphalt deposited at the bottom of the reservoir to the upper part of the reservoir. During the stirring process of the asphalt, the stirring assembly drives the adjustment assembly to move the tire base material up and down, so that the asphalt can enter the structure of the stretched tire base material. In the process of moving the tire base, the adjustment assembly can smooth out wrinkles and bubbles in the tire base. Two adjacent adjustment assemblies move the tire base at opposite paces, which can reduce the resistance of the tire base material when it moves up and down in the asphalt.

[0013] The molding assembly is used to wipe off the excess asphalt wrapped on the surface of the tire base material. Under the premise that the speed of transferring the tire base material by the two transfer rollers remains unchanged, when the adjustment assembly moves the elastic tire base material, the tire base material reacts to the molding assembly, driving the molding assembly to move toward the direction close to the adjustment assembly. The molding assembly fills the excess asphalt into the gap in the asphalt raw material on the tire base material.

[0014] As a further improvement of this technical solution, a guide slope is provided at the bottom of the storage tank, the height of the guide slope close to the stirring component is lower than the height of the guide slope away from the stirring component, and the side wall of the transfer roller is provided with several fans at the top of the roll material discharge port.

[0015] As a further improvement of the present technical solution, the stirring assembly includes a main rod, a stirring paddle is coaxially connected to the bottom of the main rod, the main rod is driven by a motor, and a worm is coaxially connected to the main rod above the stirring paddle.

[0016] As a further improvement of the present technical solution, the radius of the stirring paddle gradually decreases from low to high.

[0017] As a further improvement of the present technical solution, the adjustment assembly includes a worm wheel meshing with the worm, and a protrusion is coaxially connected to the side of the worm wheel away from the main rod.

[0018] As a further improvement of the present technical solution, the rotation steps of the two adjacent protrusions are opposite, and when the flange of one of the protrusions is at the highest point, the flange of the other protrusion is at the lowest point.

[0019] As a further improvement of the present technical solution, the forming assembly includes a support roller arranged on the inner side of the coil discharge port of the storage tank, the storage tank has a pair of adjustment grooves above the support roller, and adjustment seats are provided in the two adjustment grooves, and an extrusion roller is provided between the adjustment seat and the support roller.

[0020] As a further improvement of the present technical solution, guide rods are provided in the two adjustment slots, the adjustment seat is slidably connected to the guide rods, and a spring is sleeved on the outer periphery of the guide rods in the movement direction of the adjustment seat.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. In the production process of the asphalt-based waterproof membrane, a stirring assembly is provided to stir the asphalt in the storage tank so that the asphalt and the base material are fully mixed. At the same time, since the stirring paddle is arranged to have a structure that gradually decreases from the bottom to the top, the asphalt deposited at the bottom of the storage tank can be brought to the upper part of the storage tank.

[0023] 2. In the production process of the asphalt-based waterproof membrane, when the stirring assembly stirs the asphalt, the stirring assembly drives the adjusting assembly to move the base material up and down, so that the asphalt can enter the structure of the stretched base material. In the process of moving the base, the adjusting assembly can smooth out the wrinkles and bubbles of the base. The two adjacent adjusting assemblies move the base at opposite paces, which can reduce the resistance of the base material when it moves up and down in the asphalt.

[0024] 3. In the production process of the asphalt-based waterproof membrane, a forming component is provided to wipe off the excess asphalt wrapped on the surface of the base material. Under the premise that the speed of the two transfer rollers transferring the base material remains unchanged, the length of the base material soaked in asphalt in the storage tank is fixed. When the adjustment component moves the elastic base material, the elastic base material will stretch. On the one hand, it is conducive to the asphalt entering the structural gap of the base material; on the other hand, the base material reacts to the forming component, driving the extrusion roller to follow the adjustment seat and slide along the guide rod. During the relative sliding of the extrusion roller and the base material, the excess asphalt is filled into the gap of the asphalt raw material on the base material.

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] Example

[0040] See also Figures 1-8 As shown, the purpose of this embodiment is to provide a production process of asphalt-based waterproof membrane, including the following steps:

[0041] S1. Activate the tire base transfer mechanism to allow the tire base to pass through the interior of the asphalt reservoir 10, so that the interior and surface of the tire base are coated with asphalt;

[0042] S2. Start the stirring mechanism to stir the asphalt in the reservoir 10 so that the asphalt is in full contact with the tire base, and at the same time stir the asphalt deposited at the bottom of the reservoir 10 to the upper part;

[0043] S3. While the stirring mechanism is stirring the asphalt, the stirring mechanism drives the regulating mechanism to adjust the tightness of the tire base material so that the asphalt can enter the structure of the tire base material. At the same time, the regulating mechanism can smooth out wrinkles and bubbles on the surface of the tire base material.

[0044] S4. The base material is driven by the transfer mechanism to pass through the bottom of the forming mechanism. The excess asphalt wrapped on the surface of the base material is wiped off by the forming mechanism to ensure that the obtained asphalt-based waterproof membrane meets the actual needs. When the adjusting mechanism pulls the base material, the base drives the forming mechanism to move, and the excess asphalt is moved to the part of the base material where there is a gap in the asphalt raw material;

[0045] The transfer mechanism includes a pair of transfer rollers 11 disposed on opposite sides of the reservoir 10. The two transfer rollers 11 drive the tire base material through the asphalt pool in the reservoir 10. The stirring mechanism includes at least a stirring assembly 20. The regulating mechanism includes at least a regulating assembly 30. The regulating assembly 30 is disposed on one side of the stirring assembly 20. The forming mechanism includes a forming assembly 40.

[0046] The stirring assembly 20 is used to stir the asphalt in the reservoir 10 so that the asphalt and the tire base material are fully mixed. The stirring assembly 20 can stir the asphalt deposited at the bottom of the reservoir 10 to the upper part of the reservoir 10. During the stirring process of the asphalt by the stirring assembly 20, the stirring assembly 20 drives the adjustment assembly 30 to move the tire base material up and down, so that the asphalt can enter the structure of the stretched tire base material. In the process of moving the tire base, the adjustment assembly 30 can smooth out wrinkles and bubbles in the tire base. Two adjacent adjustment assemblies 30 move the tire base at opposite paces, which can reduce the resistance of the tire base material when it moves up and down in the asphalt.

[0047] The molding component 40 is used to wipe off the excess asphalt wrapped on the surface of the tire base material. Under the premise that the speed of transferring the tire base material by the two transfer rollers 11 remains unchanged, when the adjustment component 30 moves the elastic tire base material, the tire base material reacts to the molding component 40, driving the molding component 40 to move toward the direction close to the adjustment component 30. The molding component 40 fills the excess asphalt into the gap in the asphalt raw material on the tire base material.

[0048] First, the specific structure of the stirring assembly 20 is disclosed. The stirring assembly 20 includes a main rod 21, a stirring paddle 22 is coaxially connected to the bottom of the main rod 21, the main rod 21 is driven by a motor, and a worm 23 is coaxially connected to the main rod 21 above the stirring paddle 22;

[0049] The improvement lies in that the radius of the stirring paddle 22 gradually decreases from low to high. First, since the radius of the stirring paddle 22 gradually decreases from bottom to top, during rotation, the larger radius part at the bottom can generate a larger torque and stirring force, which enables the asphalt at the bottom to be subjected to a stronger stirring effect, overcome the viscosity and gravity of the asphalt, and thus be driven up; secondly, as the stirring paddle 22 rotates, the top part with a smaller radius has a relatively small contact area with the asphalt during the rising process, thereby reducing resistance, which enables the stirring paddle 22 to relatively easily push the asphalt stirred at the bottom upward; furthermore, this gradually decreasing radius design forms a flow field similar to a spiral rise during the stirring process. In this flow field, the asphalt will flow along the shape of the stirring paddle 22, and will be gradually brought from the bottom to a high place, realizing the up and down circulation stirring of the asphalt.

[0050] Next, the specific structure of the adjustment assembly 30 is disclosed. The adjustment assembly 30 includes a worm wheel 31 meshing with the worm 23. A protrusion 32 is coaxially connected to the side of the worm wheel 31 away from the main rod 21.

[0051] The improvement lies in that: the rotation pace of the two adjacent protrusions 32 is opposite, and when the flange of one of the protrusions 32 is at the highest point, the flange of the other protrusion 32 is at the lowest point; after being driven by the worm 23, the worm gear 31 drives the protrusion 32 to rotate, and the flange of the protrusion 32 stirs the tire base material passing through the bottom of the protrusion 32, so that the tire base material and the asphalt are fully mixed. At the same time, when the flange of the protrusion 32 passes through the surface of the tire base material, the wrinkles and bubbles on the tire base are smoothed out, so that the texture of the obtained asphalt-based roll material is more uniform; for the two protrusions 32 with opposite rotation paces, when the flange of one protrusion 32 presses the tire base to the lowest point, the flange of the other protrusion 32 is at the highest point, and the tire base material at its bottom is at the highest point due to the lack of external pressure. Compared with the two protrusions 32 driving the tire base up and down in the asphalt at the same time, the two protrusions 32 overcome less resistance when driving the tire base to move alternately up and down in the asphalt.

[0052] Next, the specific structure of the forming assembly 40 is disclosed. The forming assembly 40 includes a support roller disposed inside the coil discharge port of the reservoir 10. The reservoir 10 has a pair of adjustment slots 41 above the support roller. The two adjustment slots 41 are provided with adjustment seats 43. A squeezing roller 44 is provided between the adjustment seats 43 and the support roller.

[0053] The improvements are as follows: the stiffness coefficient of the tire base material is greater than the stiffness coefficient of the spring 45; a guide rod 42 is provided in each of the two adjustment slots 41, and the adjustment seat 43 is slidably connected to the guide rod 42. A spring 45 is sleeved on the outer periphery of the guide rod 42 in the direction of movement of the adjustment seat 43; under the premise that the speed of the tire base material transferred by the two transfer rollers 11 remains unchanged, the length of the tire base material soaked in asphalt in the storage tank 10 is fixed. When the flange of the protrusion 32 rotates downward to move the elastic tire base material, the elastic tire base material will stretch, which is beneficial for the asphalt to enter the structural space of the tire base material. On the other hand, the tire base material reacts on the squeezing roller 44, driving the squeezing roller 44 to slide along the guide rod 42 following the adjusting seat 43. During the relative sliding between the squeezing roller 44 and the tire base material, the excess asphalt is filled into the asphalt raw material gap on the tire base material. During the above process, the spring 45 is compressed by the adjusting seat 43; when the flange of the protrusion 32 rotates upward, the squeezing roller 44 loses the thrust of the tire base material, and the adjusting seat 43 will remove the squeezing effect on the spring 45. Under the action of the restoring force of the spring 45, the adjusting seat 43 drives the squeezing roller 44 to reset.

[0054] As the production time of the asphalt-based coil increases, the asphalt will gradually harden and settle to the bottom of the storage tank 10 due to temperature drop, oxidation, and impurity mixing.

[0055] A guide slope 12 is provided at the bottom of the storage tank 10. The height of the guide slope 12 close to the stirring component 20 is lower than the height of the side away from the stirring component 20. A plurality of fans 13 are provided on the side wall of the transfer roller 11 at the top of the coil discharge port.

[0056] The improvement is that when the asphalt hardens and settles, it will fall to various parts of the storage tank 10. Under the guidance of the guide slope 12, the gradually hardened asphalt moves toward the side of the stirring paddle 22, and under the traction of the vortex generated when the stirring paddle 22 rotates, the hardened asphalt approaches the stirring paddle 22 and is then driven to the upper part by the stirring paddle 22.

[0057] In summary, the working principle of this solution is as follows: first, start the two transfer rollers 11, allow the tire base material to be transferred between the two transfer rollers 11, and pass through the inside of the storage tank 10 containing asphalt, so that the inside and surface of the tire base are coated with asphalt.

[0058] Next, the stirring paddle 22 is started to stir the asphalt in the storage tank 10 so that the asphalt is in full contact with the tire base, and at the same time, the asphalt deposited at the bottom of the storage tank 10 is stirred to the upper part. Specifically, since the radius of the stirring paddle 22 gradually decreases from bottom to top, the larger radius part at the bottom can generate a larger torque and stirring force, which enables the asphalt at the bottom to be subjected to a stronger stirring effect, overcome the viscosity and gravity of the asphalt, and thus be driven up. In addition, during the stirring process, this gradually decreasing radius design forms a flow field similar to a spiral rise around the stirring paddle 22. In this flow field, the asphalt will flow along the shape of the stirring paddle 22, and will be gradually brought from the bottom to a high place, realizing the up and down circulation stirring of the asphalt.

[0059] Secondly, when the stirring paddle 22 stirs the asphalt, the flange of the bump 32 passes over the surface of the tire base, adjusting the tightness of the tire base so that the asphalt can enter the structure of the tire base material. At the same time, the flange of the bump 32 can also smooth out the wrinkles and bubbles on the surface of the tire base material. In addition, for the two bumps 32 with opposite rotation steps, when the flange of one of the bumps 32 presses the tire base to the lowest point, the flange of the other bump 32 is at the highest point. The tire base material at the bottom is at the highest point because it is not subjected to external pressure. Compared with the two bumps 32 driving the tire base up and down in the asphalt at the same time, the resistance overcome by the two bumps 32 when driving the tire base to move up and down alternately in the asphalt is smaller.

[0060] Finally, the base material is driven by the two transfer rollers 11 to pass through the bottom of the squeezing roller 44, and the excess asphalt wrapped on the surface of the base material is wiped off by the squeezing roller 44 to ensure that the obtained asphalt-based waterproof membrane meets the actual needs. When the flange of the protrusion 32 pulls the base material, the base drives the adjustment seat 43 in the adjustment groove 41 to move the excess asphalt to the part of the base where there is a gap in the asphalt raw material.
