Abstract
Description
Technical Field
[0001] This application relates to the field of non-woven fabric composite production technology, and particularly to a non-woven water-blocking tape composite production equipment and production process. Background Art
[0002] As an important waterproof material, non-woven water-blocking tapes are widely used in fields such as construction, medical, and agriculture. It is usually composed of composite materials such as polyester non-woven fabric, adhesives, and high-speed swelling superabsorbent resin, and has good waterproof performance and durability. With the continuous growth of market demand, improving the production efficiency and quality of non-woven water-blocking tapes has become the focus of industry attention.
[0003] In the existing production process of non-woven water-blocking tapes, one of the most common methods is manual laying. Although this method is simple to operate, it has many deficiencies. First of all, the production efficiency of manual laying is low and cannot meet the requirements of large-scale production and delivery time. Secondly, due to relying on manual operation, the product quality is greatly affected by the skill level of workers, and quality problems are likely to occur, such as uneven distribution of adhesives and superabsorbent resin, inconsistent product thickness, etc. In addition, manual laying has a high labor intensity and a poor working environment. Long-term operation is likely to cause worker fatigue, which in turn affects production safety and product quality.
[0004] Therefore, although manual laying still has certain applications in small-scale production, in the context of pursuing high-efficiency and high-quality production, the problems it presents need to be solved urgently. Summary of the Invention
[0005] In order to improve the problems existing in the above technology, this application provides a non-woven water-blocking tape composite production equipment and production process.
[0006] The non-woven water-blocking tape composite production equipment provided by this application adopts the following technical solutions: A non-woven water-blocking tape composite production equipment includes an upper unwinding device for placing the upper non-woven fabric, a lower unwinding device for placing the lower non-woven fabric, and a mounting frame. A bonding device, a feeding device, a pressing device, and a composite device are arranged on the mounting frame. The bonding device, the feeding device, the pressing device, and the composite device are all located between the upper non-woven fabric and the lower non-woven fabric and are arranged in sequence along the transmission direction of the non-woven fabric. The bonding device is used to coat the adhesive on the upper non-woven fabric and / or the lower non-woven fabric. The feeding device is used to put the composite material on the upper non-woven fabric and / or the lower non-woven fabric coated with the adhesive. The pressing device is used to press the upper non-woven fabric and the lower non-woven fabric together. The composite device is used to perform hot pressing and composite treatment on the pressed non-woven fabric.
[0007] By adopting the above technical solutions, the upper unwinding device and the lower unwinding device are respectively used to place the upper non-woven fabric and the lower non-woven fabric as raw materials. During the composite production of the non-woven water-blocking tape, the upper non-woven fabric and the lower non-woven fabric will move on the mounting rack. During this process, the bonding device first coats the adhesive on the upper non-woven fabric and / or the lower non-woven fabric. Since the bonding device is located between the upper non-woven fabric and the lower non-woven fabric, the adhesive will be applied between the upper non-woven fabric and the lower non-woven fabric to form an adhesive layer. After that, the non-woven fabric moves to the feeding device, and the feeding device coats composite materials such as high-speed swelling superabsorbent polymers on the upper non-woven fabric and / or the lower non-woven fabric. Since the adhesive is coated on the upper non-woven fabric and / or the lower non-woven fabric, the composite material can be adhered to the non-woven fabric and / or the lower non-woven fabric to form a composite material layer. Subsequently, the upper non-woven fabric and the lower non-woven fabric move to the pressing device, and the pressing device presses the upper non-woven fabric and the lower non-woven fabric together. The upper non-woven fabric, the adhesive layer, the composite material layer and the lower non-woven fabric are laminated layer by layer, and the composite material can be firmly attached to the non-woven fabric. Finally, the pressed non-woven fabric moves to the composite device. The composite device utilizes the thermoplasticity of the composite material. After being heated to a certain temperature, it will soften and melt, and then be pressed together to tightly bond the non-woven fabrics to form an integral body, thus completing the composite production of the non-woven water-blocking tape.
[0008] The cooperation of each component in the above process can complete the composite production of the non-woven water-blocking tape. The entire production process has a high degree of automation, a low degree of manual intervention and a low manual output cost, and the production efficiency and product quality of the non-woven water-blocking tape have been improved. In addition, the combined cooperation of the bonding device and the feeding device can achieve the uniform coating and feeding of the adhesive and the composite material, avoiding the inconsistencies caused by manual operation, and ensuring the quality stability of each batch of products. The pressing device and the composite device cooperate together to complete multiple pressing and hot pressing composite treatments, further enhancing the structural strength and waterproof performance of the non-woven water-blocking tape.
[0009] Optionally, the bonding device includes a storage box and a coating roller arranged on the mounting rack. The storage box stores the adhesive, and the coating roller is rotatably arranged in the storage box and can contact the side of the lower non-woven fabric close to the upper non-woven fabric.
[0010] By adopting the above technical solutions, when the coating roller rotates in the storage box, it will dip an appropriate amount of adhesive and transfer it to the lower non-woven fabric, so that the adhesive is evenly coated on the side of the lower non-woven fabric close to the upper non-woven fabric. The combined cooperation of the coating roller and the storage box can ensure the uniform distribution of the adhesive, avoid the overuse of the adhesive, thereby improving the production efficiency and product quality. Finally, the non-woven fabric treated by the coating roller can be better combined with the composite material, ensuring the smooth progress of the subsequent processes.
[0011] Optionally, along the transmission direction of the non-woven fabric on the mounting frame, an adjusting roller is provided between the lower unwinding device and the coating roller. An adjusting member for adjusting the height of the adjusting roller is provided on the mounting frame, and the adjusting roller abuts against the side of the lower non-woven fabric away from the coating roller.
[0012] By adopting the above technical solution, the adjusting roller is arranged between the lower unwinding device and the coating roller, and its height is adjusted by the adjusting member. When the non-woven fabric is transmitted from the lower unwinding device, the adjusting roller can adjust the tension and flatness of the non-woven fabric as needed to ensure the smooth docking of the non-woven fabric with the coating roller. Specifically, the height adjustment function of the adjusting roller can effectively prevent the non-woven fabric from wrinkling or deviating from the track due to slack, thus ensuring the uniform application of the adhesive in the subsequent coating process. At the same time, the adjusting roller can also adapt to non-woven fabrics of different thicknesses and materials, improving the applicability and production flexibility of the equipment. Finally, this design not only improves the quality and consistency of the product, but also significantly reduces the production failure rate and improves the overall production efficiency.
[0013] Optionally, the feeding device includes a hopper arranged on the mounting frame. The hopper stores composite materials. A plurality of lower discharge ports are opened at the bottom of the hopper, and a lower coating roller that can contact the side of the lower non-woven fabric close to the upper non-woven fabric is rotatably arranged at the lower discharge port.
[0014] By adopting the above technical solution, the composite materials in the hopper can be evenly fed onto the lower non-woven fabric through the plurality of lower discharge ports. The rotation of the lower coating roller not only helps the composite materials to be smoothly discharged from the lower discharge ports, but also ensures a more uniform distribution of the composite materials on the lower non-woven fabric. This design effectively avoids the problem of uneven material distribution that may occur in traditional manual laying, improving the quality and consistency of the product. At the same time, by adjusting the rotation speed of the lower coating roller, the feeding amount of the composite materials can be flexibly adjusted according to the actual production needs, further enhancing the adaptability and production efficiency of the equipment.
[0015] Optionally, a baffle for partially blocking the discharge port is slidably arranged on the hopper, and a fixing member for fixing the position of the baffle is arranged on the hopper.
[0016] By adopting the above technical solution, the baffle can slide on the hopper to partially block the discharge port, effectively controlling the feeding amount of the composite material. At the same time, the fixing member can lock the position of the baffle to ensure that the baffle does not shift during the production process, guaranteeing the stability and consistency of the feeding amount. This design not only improves the accuracy of feeding but also reduces product quality problems caused by excessive or insufficient feeding. In addition, by adjusting the position of the baffle, the feeding amount of the composite material can be flexibly adjusted according to actual production needs, adapting to the production of non-woven water-blocking tapes with different specifications and performance requirements, and further enhancing the applicable range and production efficiency of the equipment.
[0017] Optionally, a coating roller is rotatably arranged on the mounting frame and can contact the side of the upper non-woven fabric close to the lower non-woven fabric. The composite material is stored in the coating roller, and a discharge port for discharging the composite material is provided on the coating roller.
[0018] By adopting the above technical solution, during the transmission of the non-woven fabric, the coating roller can continuously and evenly coat the composite material stored inside on the side of the upper non-woven fabric close to the lower non-woven fabric. The rotation of the coating roller ensures the continuous supply of the composite material, and the design of the discharge port enables the composite material to be accurately discharged and adhered to the non-woven fabric. This design not only improves the uniformity and consistency of coating but also reduces errors and instabilities caused by manual operation. At the same time, the coordinated action of the upper coating roller and the lower coating roller further ensures the uniform distribution of the composite material on the entire non-woven fabric, thus improving the quality and production efficiency of the final product.
[0019] Optionally, the pressing device includes pressing rollers arranged oppositely, and flattening rollers arranged oppositely can respectively contact the sides of the upper non-woven fabric and the lower non-woven fabric facing away from each other.
[0020] By adopting the above technical solution, the oppositely arranged pressing rollers in the pressing device can effectively press the upper non-woven fabric and the lower non-woven fabric tightly, ensuring that the upper non-woven fabric and the lower non-woven fabric fully contact and fit tightly after being coated with adhesive and composite material. Specifically, the oppositely arranged pressing rollers can not only effectively apply pressure to make the bonding between the non-woven fabrics more firm, reducing the generation of voids and bubbles, thereby improving the flatness and density of the product; at the same time, the design of the flattening rollers can further eliminate the warping phenomenon that may occur at the edges of the non-woven fabric, ensuring the dimensional stability and appearance quality of the final product.
[0021] Optionally, a curing lamp holder is arranged on the mounting frame, a curing lamp is arranged on the curing lamp holder, a driving roller is rotatably arranged on the curing lamp holder, and a channel for the non-woven fabric to pass through is formed between the driving roller and the curing lamp; there are two groups of pressing devices, and the curing lamp holder is located between the two groups of pressing devices.
[0022] By adopting the above technical solution, the curing lamp on the curing lamp holder can quickly cure the non-woven fabric when it passes by. The channel between the driving roller and the curing lamp ensures that the non-woven fabric can be fully exposed within the action range of the curing lamp when passing through this area, thereby improving the uniformity and efficiency of curing. At the same time, two sets of pressing devices are respectively located on both sides of the curing lamp holder. The first set of pressing devices first preliminarily presses the upper and lower non-woven fabrics coated with adhesives and composite materials, then completes the curing process through the curing lamp, and finally is further compacted by the second set of pressing devices to ensure the tight combination between the non-woven fabrics. This design not only improves the stability and reliability of the product, but also significantly improves the overall production efficiency.
[0023] In the actual production process of the non-woven water-blocking tape, the non-woven fabric can be directly pressed twice through two sets of pressing devices to ensure the tight combination between the non-woven fabric materials. At the same time, according to production requirements, the line can be adjusted after the first pressing to make the non-woven fabric pass through the UV curing lamp for curing treatment, and then the second pressing is carried out to further improve the stability and quality of the product.
[0024] Optionally, the composite device includes two layers of hot pressing rollers rotatably arranged on the mounting frame. A channel for the non-woven fabric to pass through is formed between the two layers of hot pressing rollers, and a heating member for heating the hot pressing rollers is arranged on the mounting frame.
[0025] By adopting the above technical solution, the two layers of hot pressing rollers can rotate stably on the mounting frame to form a channel for the non-woven fabric to pass through. The heating member makes the hot pressing rollers reach a predetermined temperature to ensure that the non-woven fabric material softens and melts at high temperature. When the non-woven fabric passes through this channel, the pressing action of the hot pressing rollers causes the upper and lower non-woven fabrics to fit tightly, and at the same time, the adhesives and composite materials are fully fused, thereby enhancing the overall structural strength and waterproof performance of the non-woven water-blocking tape.
[0026] A non-woven water-blocking tape composite production process provided by the present application, using the above-mentioned non-woven water-blocking tape composite production equipment, includes the following steps: S1: Install the upper non-woven fabric and the lower non-woven fabric on the upper non-woven fabric unwinding device and the lower non-woven fabric unwinding device respectively; S2: Use the bonding device to coat the adhesive on the opposite side of the lower non-woven fabric and / or the upper non-woven fabric; S3: Use the coating device to put in the composite material so that the composite material is adhered to the upper non-woven fabric and / or the lower non-woven fabric through the adhesive; S4: Use the pressing device to press the upper and lower non-woven fabrics coated with the composite material; S5: Use the composite device to perform hot pressing and composite treatment on the pressed non-woven fabric.
[0027] In summary, the present application includes at least one of the following beneficial technical effects: 1. The composite production of the non-woven water-blocking tape can be completed. The entire production process has a high degree of automation, a low degree of manual intervention, and a low manual output cost. The production efficiency and product quality of the non-woven water-blocking tape have been improved. In addition, the combined operation of the bonding device and the feeding device can achieve uniform coating and feeding of the adhesive and the composite material, avoiding the inconsistencies caused by manual operation and ensuring the quality stability of each batch of products. The pressing device and the composite device cooperate together to complete multiple pressing and hot-pressing composite treatments, further enhancing the structural strength and waterproof performance of the non-woven water-blocking tape; 2. The adjusting roller is arranged between the lower unwinding device and the coating roller, and its height is adjusted by the adjusting member. When the non-woven fabric is transmitted from the lower unwinding device, the adjusting roller can adjust the tension and flatness of the non-woven fabric as needed to ensure the smooth docking of the non-woven fabric with the coating roller. Specifically, the height adjustment function of the adjusting roller can effectively prevent the non-woven fabric from wrinkling or deviating from the track due to relaxation, thus ensuring the uniform application of the adhesive during the subsequent coating process. At the same time, the adjusting roller can also adapt to non-woven fabrics of different thicknesses and materials, improving the applicability and production flexibility of the equipment. Ultimately, this design not only improves the product quality and consistency but also significantly reduces the production failure rate and increases the overall production efficiency; 3. During the actual production process of the non-woven water-blocking tape, the non-woven fabric can be directly pressed twice through two groups of pressing devices to ensure the tight combination between the non-woven fabric materials. At the same time, according to production requirements, the line can be adjusted after the first pressing, so that the non-woven fabric passes through the UV curing lamp for curing treatment and then undergoes the second pressing, further improving the stability and quality of the product.

Detailed implementation manners
[0030] The following further elaborates on this application Figures 1-6 in conjunction with the attached drawings.
[0031] Embodiment 1 Embodiment 1 of this application discloses a non-woven water-blocking tape composite production device. Referring to Figure 1 and Figure 2 , the non-woven water-blocking tape composite production device includes an upper unwinding device 1 for placing the upper non-woven fabric, a lower unwinding device 2 for placing the lower non-woven fabric, and a mounting frame 3. A bonding device 4, a feeding device 5, a pressing device 6, and a composite device 7 are arranged on the mounting frame 3. These devices are all located between the upper non-woven fabric and the lower non-woven fabric and are arranged in sequence along the transmission direction of the non-woven fabric. This configuration realizes the automated production of non-woven water-blocking tapes, improving production efficiency and product quality.
[0032] Referring to Figure 1 and Figure 3 , the upper unwinding device 1 and the lower unwinding device 2 adopt the same structure. Both of them include an unwinding rack 15. Two groups of mounting rollers 16 are arranged on the unwinding rack 15. Each group of mounting rollers 16 includes two oppositely arranged mounting rollers 16. The two oppositely arranged mounting rollers 16 are used to mount a roll of non-woven fabric, and the mounting rollers 16 are rotatably connected to the unwinding rack 15. A cylinder is arranged on one of the two oppositely arranged mounting rollers 16. The movable end of the cylinder is horizontally arranged and is coaxially rotatably connected to the corresponding mounting roller 16.
[0033] When placing the non-woven fabric on the unwinding rack 15, the core shaft of the non-woven fabric roll can be docked with the mounting roller 16, so that one of the mounting rollers 16 is inserted into the core shaft of the non-woven fabric roll. The cylinder drives the corresponding mounting roller 16 to move, so that both mounting rollers 16 are inserted into the core shaft of the non-woven fabric roll, and the installation of the non-woven fabric roll is thus completed. Since two groups of mounting rollers 16 are arranged on each unwinding rack 15, during the production of non-woven water-blocking tapes, when one roll of non-woven fabric is used up, it can be directly switched to another roll for discharging without stopping the production equipment.
[0034] Referring to Figure 1 and Figure 4 Figure 4 , the bonding device 4 includes a storage box 41 and a coating roller 42. An adhesive is stored in the storage box 41. The coating roller 42 is rotatably arranged in the storage box 41 and can contact the side of the lower non-woven fabric close to the upper non-woven fabric. When the coating roller 42 rotates in the storage box 41, it will dip up an appropriate amount of adhesive and transfer it to the lower non-woven fabric, ensuring that the adhesive is evenly coated on the side of the lower non-woven fabric close to the upper non-woven fabric. In addition to the coating roller 42, a spray head or a brush can also be selected as an alternative, and these solutions can also achieve the even distribution of the adhesive.
[0035] Referring to Figure 1 and Figure 5 Figure 5 , an upper coating roller 10 that can contact the side of the upper non-woven fabric close to the lower non-woven fabric is rotatably arranged on the mounting frame 3. A composite material is stored in the upper coating roller 10, and an upper discharge port 11 for discharging the composite material is provided on the upper coating roller 10. The upper coating roller 10 can continuously and evenly coat the internally stored composite material on the side of the upper non-woven fabric close to the lower non-woven fabric during the transmission of the non-woven fabric. The rotation of the upper coating roller 10 ensures the continuous supply of the composite material, and the design of the upper discharge port 11 enables the composite material to be accurately discharged and adhered to the non-woven fabric.
[0036] Referring to Figure 1 and Figure 6 Figure 6 , the feeding device 5 includes a hopper 51. A composite material is stored in the hopper 51. A plurality of lower discharge ports 52 are provided at the bottom of the hopper 51, and a lower coating roller 53 that can contact the side of the lower non-woven fabric close to the upper non-woven fabric is rotatably arranged at the lower discharge ports 52. The rotation of the lower coating roller 53 not only helps the composite material to be smoothly discharged from the lower discharge ports 52, but also ensures a more even distribution of the composite material on the lower non-woven fabric. In addition, a vibrating screen or a screw feeder can be selected as an alternative, and these solutions can also achieve the even feeding of the composite material.
[0037] In the embodiment of the present application, rough particles are provided on the surface of the lower coating roller 53, which facilitates the adhesion of the composite material. The lower coating roller 53 is driven by a motor to rotate, so that the rotation speed of the lower coating roller 53 can be controlled, and thus even feeding can be achieved.
[0038] Referring to Figure 1 and Figure 2, the laminating device 6 includes laminating rollers 61 arranged oppositely, and the flattening rollers arranged oppositely can respectively contact the sides of the upper non-woven fabric and the lower non-woven fabric that face away from each other. The oppositely arranged laminating rollers 61 in the laminating device 6 can effectively laminate the upper non-woven fabric and the lower non-woven fabric tightly, ensuring that the upper non-woven fabric and the lower non-woven fabric are in full contact and tightly adhered after being coated with adhesive and composite materials. In addition, the design of the flattening rollers can further eliminate the warping phenomenon that may occur at the edges of the non-woven fabric, ensuring the dimensional stability and appearance quality of the final product. A hydraulic press or a pneumatic press can also be selected as an alternative, and these solutions can provide greater pressure to ensure better laminating effect.
[0039] Referring to Figure 1 and Figure 2 , the composite device 7 includes two layers of hot pressing rollers 71 rotatably arranged on the mounting frame 3. The hot pressing rollers 71 are driven to rotate by a motor. The two layers of hot pressing rollers 71 are arranged staggeredly, and a channel for the non-woven fabric to pass through is formed between the two layers of hot pressing rollers 71. A heating element for heating the hot pressing rollers 71 is arranged on the mounting frame 3. The two layers of hot pressing rollers 71 can rotate stably on the mounting frame 3 to form a channel for the non-woven fabric to pass through. The heating element heats the hot pressing rollers 71 to a predetermined temperature to ensure that the non-woven fabric material softens and melts at high temperature. When the non-woven fabric passes through this channel, the pressing action of the hot pressing rollers 71 causes the upper and lower non-woven fabrics to be tightly adhered, and at the same time, the adhesive and the composite material are fully fused, thereby enhancing the overall structural strength and waterproof performance of the non-woven water-blocking belt.
[0040] In the embodiment of the present application, the heating element is selected as a heating power grid arranged inside the hot pressing roller 71. An oil pipe 72 for connecting to the external oil circuit is arranged on the mounting frame 3. A plurality of branch pipes 73 are connected to the oil pipe 72, and each branch pipe 73 corresponds to a hot pressing roller 71 and is connected to the inside of the hot pressing roller 71. Oil is introduced into the hot pressing roller 71 through the oil pipe 72 and the branch pipes 73. The oil flows in the steel roller and is heated by the heating power grid, thereby heating the hot pressing roller 71. In addition, infrared heating or microwave heating can also be selected as an alternative, and these solutions can complete the heating process in a shorter time and improve production efficiency.
[0041] Referring to Figure 1 and Figure 2 , a winding frame 17 is further arranged at one end of the composite device 7 away from the laminating device 6. A winding roller 18 is rotatably arranged on the winding frame 17, thereby collecting the non-woven water-blocking belt after production is completed to prevent the non-woven water-blocking belt from scattering randomly.
[0042] In the embodiment of the present application, the coating roller 42, the laminating roller 61, the hot pressing roller 71, the upper coating roller 10, the mounting roller 16, and the winding roller 18 can all be driven to rotate by a motor.
[0043] The implementation principle of a non-woven water-blocking tape composite production device in an embodiment of the present application is as follows: Through the collaborative work of the above-mentioned various devices, the automated production of non-woven water-blocking tapes is achieved. The bonding device 4 ensures the uniform application of the adhesive, the feeding device 5 ensures the uniform feeding of the composite material, the pressing device 6 ensures the tight fitting of the non-woven fabric, and the composite device 7 enhances the overall structural strength and waterproof performance of the non-woven water-blocking tape through hot pressing treatment. The entire production process has a high degree of automation and less manual intervention, significantly improving production efficiency and product quality.
[0044] Embodiment 2 The difference between Embodiment 2 and Embodiment 1 lies in the addition of the design of the adjusting roller 8 and the baffle 9.
[0045] Referring to Figure 1 and Figure 2 , along the transmission direction of the non-woven fabric on the mounting frame 3, an adjusting roller 8 is provided between the lower unwinding device 2 and the coating roller 42. An adjusting member for adjusting the height of the adjusting roller 8 is provided on the mounting frame 3, and the adjusting roller 8 abuts against the side of the lower non-woven fabric facing away from the coating roller 42. The height adjustment function of the adjusting roller 8 can effectively prevent the non-woven fabric from wrinkling or deviating from the track due to relaxation, thereby ensuring the uniform application of the adhesive during the subsequent coating process. At the same time, the adjusting roller 8 can also adapt to non-woven fabrics of different thicknesses and materials, improving the applicability and production flexibility of the equipment.
[0046] In an embodiment of the present application, referring to Figure 1 and Figure 4 , the adjusting member includes an adjusting screw 19 vertically arranged on the mounting frame 3. A moving block 20 is provided at the end of the adjusting screw 19, and the rotating shaft of the adjusting roller 8 is rotatably connected to the moving block 20. A moving frame 21 is also provided on the mounting frame 3, the moving block 20 slides on the moving frame 21, and the adjusting screw 19 is threadedly connected to the moving frame 21. When adjusting the height of the adjusting roller 8, the adjusting screw 19 can be rotated, and the moving block 20 thus moves vertically within the moving frame 21, and the height of the adjusting roller 8 is thereby adjusted.
[0047] Referring to Figure 1 and Figure 5, a baffle 9 for partially blocking the discharge port is slidably arranged on the hopper 51, and a fixing member for fixing the position of the baffle 9 is arranged on the hopper 51. The baffle 9 can slide on the hopper 51 to partially block the discharge port, effectively controlling the feeding amount of the composite material. At the same time, the fixing member can lock the position of the baffle 9 to ensure that the baffle 9 will not shift during the production process, guaranteeing the stability and consistency of the feeding amount. This design not only improves the accuracy of feeding but also reduces product quality problems caused by excessive or insufficient feeding. In addition, by adjusting the position of the baffle 9, the feeding amount of the composite material can be flexibly adjusted according to actual production needs, adapting to the production of non-woven water-blocking tapes with different specifications and performance requirements, and further enhancing the applicable range and production efficiency of the equipment.
[0048] In the embodiment of the present application, a horizontal mounting plate 22 is extended and arranged at the outer bottom of the hopper 51. The mounting plate 22 is arranged in parallel with the baffle 9. A plurality of waist-shaped holes 23 are formed in the mounting plate 22. The fixing member includes an adjusting bolt 24 passing through the waist-shaped holes 23. Two fastening nuts 25 are threadedly connected to the adjusting bolt 24. The two fastening nuts 25 are respectively abutted against the baffle 9 and the mounting plate 22 to complete the fixation of the baffle 9.
[0049] The implementation principle of Embodiment 2 is as follows: By adding the design of the adjusting roller 8 and the baffle 9, the production process of the non-woven water-blocking tape is further optimized. The effective adjustment function of the adjusting roller 8 ensures the tension and flatness of the non-woven fabric, avoiding problems such as wrinkling or deviation caused by relaxation. The design of the baffle 9 precisely controls the feeding amount of the composite material, improving the feeding accuracy and stability. These improvement measures not only enhance the quality and consistency of the product but also significantly reduce the production failure rate and improve the overall production efficiency.
[0050] Embodiment 3 The difference between this Embodiment 1 and Embodiment 1 is that a curing lamp holder 12 and a double-group pressing device 6 are added.
[0051] Refer to Figure 1 and Figure 2, a curing lamp holder 12 is provided on the mounting bracket 3, a curing lamp 13 is provided on the curing lamp holder 12, a driving roller 14 is rotatably provided on the curing lamp holder 12, and a passage for the non-woven fabric to pass through is formed between the driving roller 14 and the curing lamp 13; there are two sets of pressing devices 6, and the curing lamp holder 12 is located between the two sets of pressing devices 6. The curing lamp 13 on the curing lamp holder 12 can quickly cure the non-woven fabric when it passes by. The passage between the driving roller 14 and the curing lamp 13 ensures that the non-woven fabric can be fully exposed within the action range of the curing lamp 13 when passing through this area, thereby improving the uniformity and efficiency of curing. At the same time, the two sets of pressing devices 6 are respectively located on both sides of the curing lamp holder 12. The first set of pressing devices 6 first preliminarily presses the upper and lower non-woven fabrics coated with the adhesive and the composite material, then completes the curing treatment through the curing lamp 13, and finally is further compacted by the second set of pressing devices 6 to ensure the tight combination between the non-woven fabrics. This design not only improves the stability and reliability of the product but also significantly improves the overall production efficiency.
[0052] The implementation principle of Embodiment 3 is as follows: By adding a curing lamp holder 12 and a double-group pressing device 6, the production process of the non-woven water-blocking belt is further improved. The quick curing treatment of the curing lamp 13 ensures the timely curing of the adhesive and the composite material of the non-woven fabric, improving the stability and reliability of the product. The design of the double-group pressing device 6 performs the pressing treatment in stages to ensure the tight combination between the non-woven fabrics and eliminate the generation of voids and bubbles. These improvement measures not only improve the quality and consistency of the product but also greatly improve the production efficiency, meeting the needs of large-scale production.
[0053] Embodiment 4 Embodiment 4 of the present application discloses a composite production process for a non-woven water-blocking belt, using a composite production device for a non-woven water-blocking belt in Embodiment 1, including the following steps: S1: Install the upper non-woven fabric and the lower non-woven fabric on the upper non-woven fabric unwinding device and the lower non-woven fabric unwinding device respectively; The specific steps are as follows: Wind the upper non-woven fabric on the unwinding rack 15 of the upper unwinding device 1 to ensure that the non-woven fabric is flat and free of wrinkles.
[0054] Wind the lower non-woven fabric on the unwinding rack 15 of the lower unwinding device 2 to ensure that the non-woven fabric is flat and free of wrinkles.
[0055] S2: Use the bonding device 4 to coat the adhesive on the opposite sides of the lower non-woven fabric and the upper non-woven fabric; The specific steps are as follows: Drive the coating roller 42 to rotate through the motor on the coating roller 42. The coating roller 42 rotates in the storage box 41 to dip an appropriate amount of adhesive.
[0056] The coating roller 42 contacts the lower non-woven fabric, and evenly coats the adhesive on the side of the lower non-woven fabric close to the upper non-woven fabric.
[0057] S3: Use the feeding device 5 to feed the composite material, so that the composite material is adhered to the lower non-woven fabric through the adhesive; The specific steps are as follows: Drive the lower coating roller 53 to rotate through the motor on the lower coating roller 53. The lower coating roller 53 starts to rotate, and the composite material is evenly discharged from the lower discharge port 52 at the bottom of the hopper 51.
[0058] The composite material is transferred by the lower coating roller 53 to the lower non-woven fabric to ensure uniform distribution.
[0059] S4: Use the pressing device 6 to press the upper and lower non-woven fabrics with the composite material adhered; The specific steps are as follows: The lower non-woven fabric and the upper non-woven fabric are transported between the relatively arranged pressing rollers 61, and the pressing rollers 61 initially press the upper non-woven fabric and the lower non-woven fabric.
[0060] Ensure that the pressure of the pressing rollers 61 is appropriate to make the bonding between the non-woven fabrics stronger and reduce the generation of voids and bubbles.
[0061] The non-woven fabric after the initial pressing enters the area of the curing lamp rack 12 and undergoes rapid curing treatment by the curing lamp 13.
[0062] The cured non-woven fabric enters between the second group of pressing rollers 61 and is pressed again to further compact the non-woven fabric and ensure its tight combination.
[0063] S5: Use the composite device 7 to perform hot pressing and composite treatment on the pressed non-woven fabric.
[0064] The specific steps are as follows: The pressed non-woven fabric enters the composite device 7, and the two hot pressing rollers 71 start to rotate.
[0065] The heating element makes the hot pressing rollers 71 reach a predetermined temperature to ensure that the non-woven fabric material softens and melts at high temperature.
[0066] When the non-woven fabric passes through the channel formed by the hot pressing rollers 71, it is subjected to hot pressing, prompting the upper and lower non-woven fabrics to fit tightly, and the adhesive and the composite material are fully fused.
[0067] After the hot pressing and composite treatment is completed, the finished non-woven water-blocking tape is output and ready for packaging and warehousing.
[0068] The above are all the preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
