Description

Technical Field

[0001] This application relates to the technical field of waterproof membrane processing, and in particular to a non-bitumen-based waterproof membrane production equipment, process, and quality control method. Background Technology

[0002] Currently, waterproof membranes are mainly used in building walls, roofs, tunnels, highways, and landfills, serving as a flexible building material that can be rolled up to resist external rainwater and groundwater seepage. They are the first line of defense in the entire waterproofing project and play a crucial role. To ensure the quality of waterproofing construction, quality inspection of the waterproof membrane installation is necessary, including thickness testing. With increasingly stringent quality inspection requirements, the demand for fast and convenient waterproof membrane thickness testing equipment is becoming increasingly urgent. The use of new technologies for real-time waterproof membrane testing is of great significance to the construction industry. Non-asphalt-based pre-laid reverse-adhesive products are gaining a larger share in the waterproofing market. Due to their good chemical stability, strong adhesion to substrates, and strong resistance to deformation, they are widely used in underground engineering foundations, side walls where there is no construction space, nuclear power plants, tunnels, and other special application areas.

[0003] The production of non-bitumen-based waterproof membranes generally includes the following steps: raw material mixing, melting, die extrusion molding, cooling and shaping, and winding.

[0004] In the process of developing this application, the inventors discovered that the technology has at least the following problems: after the raw materials are stirred, when the next step of melting is carried out, due to the different particle sizes and weights of the various raw materials, the heavier and lighter raw materials are prone to stratification when the mixed raw materials are transported, which affects the production of non-asphalt-based waterproof membranes. Summary of the Invention

[0005] In order to reduce raw material segregation and minimize the impact on the production of non-bitumen-based waterproof membranes, this application provides a production equipment, process, and quality control method for non-bitumen-based waterproof membranes.

[0006] Firstly, this application provides a non-bitumen-based waterproof membrane production equipment, which adopts the following technical solution:

[0007] A non-bitumen-based waterproof membrane production equipment includes a frame, a mixing device, a conveying device, a metering device, and a forming device. The mixing device includes a mixing mechanism and a storage mechanism. The mixing mechanism is mounted on the frame for mixing multiple raw materials. The storage mechanism includes a storage tank and a stirring assembly. The storage tank is mounted on the frame for receiving the raw materials mixed by the mixing mechanism. The stirring assembly is mounted on the storage tank for secondary mixing of the materials. The conveying device is mounted on the frame and receives the materials conveyed by the storage tank. The conveying device melts the materials and conveys them to the metering device. The metering device is mounted on the frame for quantitatively conveying materials into the forming device according to demand. The forming device is mounted on the frame for forming the membrane.

[0008] By adopting the above technical solution, multiple raw materials are first added to the sheet material mechanism for mixing, and then conveyed to the storage tank. The mixing component stirs the raw materials while conveying them to the conveying device for melting. The melted material is then conveyed to the metering device for metering. The molten material after metering enters the forming device to form sheets, which are then cooled and wound up. The mixing mechanism ensures that the material is stirred again before melting, reducing material grading, minimizing the impact on the processing of non-asphalt-based waterproof membranes, and improving the quality of the waterproof membrane.

[0009] Optionally, the mixing mechanism includes a mixing tank, a mixing assembly, a return pipe, a return assembly, and a discharge pipe. The mixing tank is mounted on the frame. The mixing assembly includes mixing blades, a stirring shaft, and a drive component. The stirring shaft is rotatably mounted on the mixing tank. The mixing blades are mounted on the stirring shaft. The drive component is mounted on the mixing tank and connected to the stirring shaft, driving the stirring shaft to rotate. The discharge pipe is mounted on the mixing tank and connected to the conveying device. The return pipe is mounted on the mixing tank and conveys the material to the return assembly. The return assembly is mounted on the mixing tank to mix the material and convey it back into the mixing tank for further mixing.

[0010] By adopting the above technical solution, when mixing multiple materials, the materials are added to the mixing tank, and then the mixing component drives the mixing of multiple materials. During the mixing process, the materials enter the return component through the return pipe, and then return to the mixing tank after being stirred by the return component, and the materials are mixed and stirred again. The mixing mechanism increases the disturbance of the materials, and the same part of the materials is mixed more evenly after multiple stirrings, further reducing the stratification, thereby reducing the impact on the subsequent waterproof membrane processing and improving the quality of the waterproof membrane.

[0011] Optionally, the return assembly includes a material hopper and a return auger. The material hopper is mounted on the frame and communicates with the return pipe. The return auger is mounted on the material hopper and its discharge end extends into the mixing tank.

[0012] By adopting the above technical solution, the material is stirred in the mixing tank by the mixing component, then enters the aggregate hopper, and then returns to the mixing tank through the return auger for stirring again. The set return component has a simple structure and is easy to control. The return auger can perform a coarse mixing of the material, which improves the mixing efficiency, enhances the mixing effect, and improves the quality of the waterproof membrane.

[0013] Optionally, the return auger is concentric with the mixing tank and extends to the upper part of the mixing tank. A material dispersing pipe is provided on the return auger. The end of the material dispersing pipe away from the return auger is closed. Multiple material dispersing holes are provided on the side wall of the material dispersing pipe.

[0014] By adopting the above technical solution, when the return auger lifts the material from the gathering hopper to the dispersing pipe, it is evenly dispersed into multiple directions in the mixing tank through multiple dispersing holes, thereby enhancing the mixing effect, reducing the mixing time, and improving work efficiency.

[0015] Optionally, the bulk material pipe is rotatably mounted on the return auger, and the mixing tank is provided with a rotating component. The bulk material pipe is connected to the driving component through the rotating component, and the bulk material pipe rotates in the opposite direction to the mixing blade.

[0016] By adopting the above technical solution, the return auger conveys the material into the dispersing pipe, and then the rotating component drives the dispersing pipe to rotate, so that the material has an initial rotational speed. The material with the initial rotational speed impacts the mixing blades in the opposite direction, generating an impact reaction force, which disperses the material and facilitates better mixing, thereby improving the mixing efficiency. At the same time, it can further reduce the occurrence of material stratification, improve the mixing effect, and reduce the impact on the production quality of waterproof membrane.

[0017] Optionally, the material distribution pipe is provided with a plurality of spiral material distribution blades, which are spirally arranged along the axis of the material distribution pipe and rotate in the same direction as the rotation direction of the material distribution pipe.

[0018] By adopting the above technical solution, after the material is conveyed into the distribution pipe by the return auger, the rotating component drives the distribution pipe to rotate, and multiple spiral distribution blades rotate and divert the material rack. Then, the material is thrown out through the distribution hole. The spiral distribution blades can extend the material's travel length and achieve uniform distribution, making the mixing of various materials more convenient. During the rotation of the spiral distribution blades, the material is patted, making the material mixing more uniform. At the same time, it can also play a certain crushing role, which facilitates the melting speed of subsequent materials. This allows materials of the same volume to melt quickly at the same conveying speed and temperature, and ensures that the materials melt fully. This reduces local bumps in the waterproof membrane caused by uneven melting and improves the quality of the waterproof membrane.

[0019] Optionally, the driving component is a mixing motor, which is mounted on the mixing tank; the rotating component includes a gear ring, a driving gear, and a driven gear, the driving gear is mounted on the output shaft of the mixing motor, the driven gear is rotatably mounted on the mixing tank and connected to the dispersing pipe, the driven gear meshes with the driving gear, the gear ring is rotatably mounted on the mixing tank and meshes with the driven gear, and the stirring shaft is connected to the gear ring.

[0020] By adopting the above technical solution, when mixing materials, the stirring motor drives the material distribution pipe to rotate, the material distribution pipe drives the material to rotate and disperse it into the mixing tank through the material distribution hole. At the same time, the stirring motor drives the drive gear to rotate, the drive gear drives the driven gear to rotate, the driven gear drives the gear ring to rotate, and the gear ring drives the mixing blades to rotate in the opposite direction. The material distribution pipe and the mixing blades rotate in the opposite direction. The driving and rotating parts are simple in structure and share the same drive, which reduces the waste of resources and has a high synchronization rate.

[0021] Optionally, the stirring shaft is provided with multiple anti-material blades, which are inclined and rotate in the opposite direction to the spiral dispersing blades. The anti-material blades and the spiral dispersing blades are located at the same height, and the front edge of the anti-material blades in the direction of rotation is sharpened to facilitate material cutting.

[0022] By adopting the above technical solution, the spiral dispersing blades carry the material through the dispersing holes and disperse it into the mixing tank. The material impacts the reverse dispersing blades, which in turn impact the material in the opposite direction. The reverse impact force increases, which facilitates the mixing of the material and can also achieve a certain crushing effect, which is conducive to the subsequent melting of the material.

[0023] Secondly, this application provides a non-bitumen-based waterproof membrane production process, which adopts the following technical solution:

[0024] A manufacturing process for non-bitumen-based waterproof membrane includes the following steps:

[0025] S1. Raw material mixing: Mixing and stirring multiple raw materials;

[0026] S2. Heating and conveying: heating the raw materials to a molten state and then conveying them;

[0027] S3. Filtration: Filtering the molten material to remove materials that cannot be melted or are not completely melted.

[0028] S4. Forming: Extruding molten material into sheet-like rolls;

[0029] S5. Cooling: Cooling and shaping the sheet-like roll material.

[0030] By adopting the above technical solution, the processing of non-asphalt-based waterproof membrane involves first mixing various raw materials, then conveying them to a heating position for melting at a temperature of 200 degrees Celsius. After heating, the materials become molten. The molten materials are then filtered to remove unmelted or incompletely melted materials. The filtered materials are then extruded into sheet-like rolls, which are then cooled and molded into qualified rolls. Through these process steps, the processing quality of the waterproof membrane is improved.

[0031] Optionally, after step S5, the following steps may also be included:

[0032] S6. Quality inspection: The thickness of the sheet is measured.

[0033] By adopting the above technical solution, in order to improve the product qualification rate, the thickness is measured after the roll material is formed. When an unqualified thickness is found, the processing of the waterproof roll material is stopped, and the problem is corrected in time to prevent losses.

[0034] Thirdly, this application provides a quality control method for the production of non-bitumen-based waterproof membranes, which adopts the following technical solution:

[0035] A method for quality control in the production of non-bitumen-based waterproof membranes includes:

[0036] Obtain production instructions;

[0037] Based on the current production order, retrieve the preset coil processing thickness program from the coil processing thickness library;

[0038] Based on the current processing thickness procedures, roll material production is carried out.

[0039] Monitor the thickness data of the roll material;

[0040] Determine if the monitoring data falls within the set threshold range. If yes, continue production; otherwise, issue an alarm.

[0041] By adopting the above technical solution, a production order is issued. Based on the production order, the corresponding thickness processing program is retrieved from the thickness processing library according to the processing thickness. Various parts of the equipment are adjusted, and then the roll material is produced. The thickness of the produced sheet material is monitored to determine whether the monitored thickness data falls within the set threshold range. If it does, production continues; if not, an alarm is issued. Upon hearing the alarm, the staff stops production, checks the equipment for problems, and resumes production after the problems are resolved. This method can monitor product quality, improve the quality of products leaving the factory, and promptly detect product problems, reducing resource waste and lowering costs.

[0042] Optionally, when monitoring the thickness data of the roll material, multiple points are monitored along the width direction of the roll material, and the monitoring data are numbered.

[0043] By adopting the above technical solutions and implementing multi-point monitoring, it is easier to control the overall product quality, reduce the randomness of individual testing points, make the test results more accurate, reduce the time wasted on accidental downtime, improve work efficiency, reduce manpower waste, and lower costs.

[0044] Optionally, when determining whether the monitoring data falls within the set threshold range, the system checks whether each data point falls within the set threshold range according to its number. If not, it checks whether consecutive points do not fall within the threshold range. If so, it issues a beeping alarm; otherwise, it issues a tapping alarm.

[0045] By adopting the above technical solution, multiple points are individually judged according to their numbers to determine whether they fall within the set threshold range. After the multi-point judgment is completed, for those points that do not fall within the set threshold range, it is judged whether they are consecutive points. If so, a beeping alarm is issued, and the staff stops the equipment production upon hearing the alarm. Then, based on the alarm sound, the staff focuses on detecting the problem at a specific node of the equipment, which facilitates quick problem detection and handling, allowing the production of waterproof membrane to resume quickly. If not, a clicking alarm is issued to remind the staff to stop the equipment. Then, based on the alarm sound, the staff focuses on detecting the problem at a specific node of the equipment, which facilitates quick problem detection and timely handling.

[0046] Optionally, if consecutive points do not fall within the threshold range, the comparison result is used to determine whether there is a threshold adjacent to the roll thickness data. If so, the roll processing thickness data associated with the threshold is retrieved, and a starting mark is made on the produced roll. If not, the alarm sound frequency is increased and an alarm message is output.

[0047] By adopting the above technical solution, if consecutive points do not fall within the set threshold range, the system retrieves whether there is a threshold for matching thickness data from the waterproof membrane library. If so, production continues, and the points where the data changes are marked for easy identification by staff to facilitate roll replacement and subsequent membrane recycling. If not, the alarm frequency is increased, and staff who hear the higher alarm frequency quickly stop the equipment. Through the above method, the probability of membrane waste is further reduced, resource utilization is improved, equipment downtime is reduced, and energy consumption during equipment startup is reduced.

[0048] In summary, this application includes the following beneficial technical effects:

[0049] 1. The mixing mechanism ensures that the materials are stirred again before melting, reducing material grading, minimizing the impact on the processing of non-asphalt-based waterproof membranes, and improving the quality of waterproof membranes.

[0050] 2. Issue a production order. Based on the production order, retrieve the corresponding thickness processing program from the thickness database according to the processing thickness, adjust various parts of the equipment, and then produce the roll material. Monitor the thickness of the produced sheet material to determine if the monitored thickness data falls within the set threshold range. If it does, production continues; if not, an alarm is issued. Upon hearing the alarm, staff stop production, check for equipment problems, and resume production after the problem is resolved. This method can monitor product quality, improve the quality of outgoing products, and promptly detect product problems, reducing resource waste and lowering costs.

[0051] 3. If consecutive points do not fall within the set threshold range, retrieve the threshold data matching the thickness from the waterproof membrane library. If so, continue production and mark the points where the data changes for easy identification by staff and roll replacement, facilitating subsequent membrane recycling. If not, increase the alarm frequency; staff hearing a higher alarm frequency should quickly stop the equipment. By setting the above method, the probability of membrane waste is further reduced, resource utilization is improved, equipment downtime is reduced, and energy consumption during equipment startup is reduced.

The first detection wheel 6300 and the second detection wheel 6400 rotate in the same direction and along the direction of movement of the waterproof membrane. Ten sliders are fixedly connected to the frame 1000. Each slider corresponds to one of the ten second wheel frames 6200. A rodless cylinder 6500 is fixedly connected to the slider.

[0074] The implementation principle of a non-asphalt-based waterproof membrane production equipment according to an embodiment of this application is as follows: Multiple materials are added to the mixing tank 2110 in a specified proportion. Then, the mixing motor 2123 is started. The mixing motor 2123 drives the drive gear 2147 to rotate, which in turn drives the driven gear 2148 to rotate. The driven gear 2148 drives the distributing pipe 2143 to rotate, the drive gear 2147 drives the gear ring 2146 to rotate, which in turn drives the rotating disk 2124 to rotate. The rotating disk 2124 drives the mixing blades 2121 to stir the materials. During the stirring process, the return valve is opened... Material enters the material collection hopper 2141 through the return pipe 2130, and then is conveyed into the dispersing pipe 2143 by the return auger 2142. As the dispersing pipe 2143 rotates, the spiral dispersing blades 2144 throw the material onto the reversing blades 2145. The reversing blades 2145, rotating in the opposite direction with the mixing blades 2121, cut the material, thus crushing and better mixing it. After mixing is complete, the return pipe 2130 is closed, and the material then enters the feeding hopper 2230 through the discharge pipe 2150. The feeding auger 2240 then conveys the material... Upon entering the storage tank 2210, to reduce material stratification, the stirring motor 2221 is activated. The stirring motor 2221 drives the mixing blades 2222 to rotate, ensuring the material entering the screw extruder is uniform. The material is then heated and melted in the screw extruder, reaching a molten state. After passing through the screw extruder, the material is filtered through a filter screen. The filtered material then enters the metering pump 4300, which controls the flow rate as needed, ensuring an appropriate amount of material enters the waterproof membrane processing die 5100. The material then passes through the waterproof membrane processing die 5100 to form sheet rolls. The material is then extruded by two forming rollers 5200 and cooled by a cooling roller 5300 to form a waterproof membrane. The sliding block of the rodless cylinder 6500 drives the slider to slide, so that the rodless cylinder 6500 drives the second detection wheel 6400 on the second wheel frame 6200 to press the waterproof membrane against the first detection wheel 6300. The rodless cylinder 6500 slides and pulls the wire-type displacement sensor 6600. The stroke of the wire-type displacement sensor 6600 is the thickness of the membrane. If the thickness is qualified, the membrane is wound up. If it exceeds the specified requirements, the staff stops production and calibrates the production equipment.

[0075] This application also discloses a production process for non-bitumen-based waterproof membranes.

[0076] refer to Figure 8 The production process of non-bitumen-based waterproof membranes includes the following steps:

[0077] S1. Raw material mixing: Adjust the material ratio according to the requirements of waterproof membrane, and add multiple materials to the production equipment for mixing and stirring;

[0078] S2. Heated conveying: After the materials are mixed, they are heated to a molten state in the production equipment and then conveyed.

[0079] S3. Filtration: The molten material is conveyed and filtered through the production equipment to remove materials that cannot be melted or are not completely melted.

[0080] S4. Forming: The molten material is extruded through production equipment to form sheet-like rolls.

[0081] S5. Cooling: The sheet-like roll material is cooled and shaped by the production equipment.

[0082] S6. Quality inspection: The thickness of the sheet roll is measured by the production equipment. When the thickness meets the threshold of ±1mm set for the production roll, the production of the roll continues. When it exceeds the above threshold, production is stopped and the production equipment is inspected and corrected.

[0083] The implementation principle of a non-asphalt-based waterproof membrane production process in this application embodiment is as follows: Based on the requirements of the waterproof membrane, the material ratio is adjusted, and various materials are added to the production equipment for mixing and stirring; the materials are heated to a molten state in the production equipment, and the molten materials are conveyed and filtered through the production equipment to remove materials that cannot be melted or are not completely melted; the molten materials are extruded through the production equipment to form sheet-like membranes; then, after cooling and shaping, the thickness of the membrane is tested to see if it meets production requirements.

[0084] This application also discloses a method for quality control in the production of non-bitumen-based waterproof membranes.

[0085] refer to Figure 9 Quality control methods for the production of non-bitumen-based waterproof membranes include:

[0086] S110, Obtain production instructions;

[0087] Specifically, production instructions can be issued through input between staff, control and issuance by a host computer, or direct control and start-up via remote control.

[0088] S120. Based on the current production instruction, retrieve the preset coil processing thickness program from the coil processing thickness library; wherein, the coil processing thickness library stores a variety of coil processing thicknesses and a variety of coil processing widths.

[0089] S130. Based on the current processing thickness program, control and adjust the output thickness of the production equipment, and then proceed with the production of the roll material.

[0090] S140. Monitor the thickness data of the waterproof membrane. Control the first detection wheel 6300 and the second detection wheel 6400 to press against the waterproof membrane using the rodless cylinder 6500. The wire-type displacement sensor 6600 obtains the thickness data of the waterproof membrane.

[0091] S150. Determine whether the monitoring data falls within the set threshold. If yes, continue production; otherwise, issue an alarm.

[0092] Specifically, the monitored thickness value is compared with the thickness value of the waterproof membrane during processing to determine whether the monitored thickness value exceeds the required value of ±1mm for the waterproof membrane. If so, an alarm is issued, which can be a beeping sound, and the staff can issue an order to stop production. If not, the waterproof membrane meets the production requirements and production can continue.

[0093] Reference Figure 10 After S150, S151-S153 can also be executed:

[0094] S151. When monitoring the thickness data of the roll material, multiple monitoring points are carried out along the width direction of the roll material, and the monitoring data are numbered and a data report is generated according to the numbering.

[0095] Specifically, the starting direction of the numbering can be set, and the numbering can be carried out along the width of the roll material according to the starting direction.

[0096] S152. Determine whether the monitoring data falls within the set threshold. Determine whether each data point falls within the set threshold range according to its number. If so, determine whether consecutive points are outside the threshold range. If so, issue a beeping alarm. If not, issue a tapping alarm.

[0097] Specifically, when the monitored width is greater than the width of the rolled material processing, the monitoring data is judged. It can be determined whether the difference from the set rolled material processing thickness is too large. When the difference is too large, it is an invalid endpoint, and no data is recorded for this segment of data, nor will an alarm be triggered for this segment of data.

[0098] S153. If a continuous point does not fall within the threshold range, then based on the comparison result, determine whether there is a threshold range for adjacent roll thickness data. If so, retrieve the roll processing thickness data associated with that threshold and make a starting mark on the produced roll. If not, increase the alarm sound frequency and output alarm information.

[0099] Specifically, during the production of waterproof membrane, if the thickness exceeds the threshold by a large margin, it is generally due to a damaged filter screen causing unmelted material or impurities to participate in the processing of the waterproof membrane. This situation is relatively rare. If the thickness is significantly less than the minimum threshold range, it is generally due to insufficient raw material supply, resulting in a membrane thickness that is less than the set thickness. In this case, there are two possibilities: one is filter screen blockage, which slows down the material flow; the other is insufficient material or an excessively slow feeding speed. When the thickness exceeds the threshold range, no data comparison is performed; an alarm message is directly output, and a rapid, intermittent alarm is issued. When the thickness is less than the threshold range, the monitoring data is compared sequentially with the waterproof membrane thickness threshold that is less than the set thickness. If a matching membrane thickness data is found, a starting mark is made on the membrane being produced, and a gentler alarm is issued. Workers can stop or continue production. When the thickness fluctuation occurs again, the above steps are repeated. If no matching membrane thickness data is found, the alarm frequency is increased, and an alarm message and data report are output.

[0100] The implementation principle of the non-asphalt-based waterproof membrane production quality control method in this application embodiment is as follows: Waterproof membrane production is carried out based on production instructions. During the production process, the processing thickness of the waterproof membrane is monitored, and multiple monitoring data points are acquired and numbered. The data is then compared sequentially with a set threshold according to the number. When consecutive points do not fall within the threshold range, it is determined whether the thickness is greater than or less than the set threshold. If it is less than the set threshold, it is compared and matched with other preset waterproof membrane processing thickness thresholds. When it falls within the range of other waterproof membrane processing thickness thresholds, production continues, and an alarm is issued. Workers can determine the problem and whether to stop the machine based on the alarm sound. If the thickness exceeds the set threshold, an intermittent alarm is output; if it is not a case of consecutive points not falling within the threshold range, the alarm sound frequency is increased, and alarm information is output.

[0101] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
