Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of continuous felt processing, and particularly relates to a seaming continuous felt manufacturing process and device. BACKGROUND

[0002] The seaming continuous felt process, also known as a glass fiber seaming felt production process, is a kind of efficient and continuous glass fiber reinforced material production technology. Glass fiber is a kind of inorganic non-metallic material with excellent performance, and has various types. The advantages of glass fiber are good insulation, strong heat resistance, good corrosion resistance, and high mechanical strength. However, the disadvantage of glass fiber is brittleness and poor wear resistance. The glass fiber seaming felt is a thin sheet product made by randomly combining continuous raw filaments or chopped raw filaments together through chemical bonding agents or mechanical action. The glass fiber seaming felt is widely used in the fields of ships, transportation, construction, and corrosion prevention. At present, in the cooling and compaction process of the seaming continuous felt, the seaming continuous felt is directly air-cooled or water-cooled and conveyed into two rotating rollers, and the two rotating rollers are used to cool and compact the upper and lower surfaces of the seaming continuous felt. In order to ensure the cooling quality of the seaming continuous felt, the two rotating rollers need to cool and compact the seaming continuous felt for a long time. Long-time cooling and compaction is easy to cause defects such as interlayer debonding, thermal stress cracking, and fiber damage. One-time cooling and compaction of the seaming continuous felt is easy to cause defects such as excessive compression of the fiber, fiber fracture, surface indentation, interlayer debonding, and thermal stress cracking, and further improves the mechanical strength, size stability, and environmental resistance of the seaming continuous felt.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0022] In one implementation, refer to Figures 1-10A continuous felt manufacturing process includes: filament extraction: glass fiber filaments are stored and continuously extracted via a yarn rack; yarn splitting: the filaments are evenly divided into multiple bundles using a yarn splitting device and guided to a yarn spreading station; felt formation: the bundled filaments are evenly spread onto a conveyor belt using a yarn spreading machine head to form an initial felt; thinning: the felt is thinned using a yarn pressing device to optimize fiber distribution density and improve subsequent weaving efficiency; stitching and bonding: the thinned felt is woven using a stitching machine head to form a continuous woven felt structure; baking and curing: the woven felt blank is placed in an oven and curing furnace for drying and curing to complete resin bonding or fiber bonding; cooling and compaction: the cured felt is cooled and compacted to enhance structural stability; cutting and winding: the felt is longitudinally cut to a set width using a slitting device, and finally, the finished felt is wound up by a winding device.

[0023] This approach first employs a modular yarn rack system to store multiple rolls of glass fiber filaments according to process requirements. A constant tension control device ensures continuous and stable filament extraction, matching the extraction speed with the pace of subsequent processes. This prevents filament breakage or tension fluctuations from affecting the uniformity of the felt. Furthermore, an integrated online detection device monitors the filament diameter, moisture content, and surface defects in real time, automatically marking or removing abnormal filaments to ensure consistent raw material quality. Then, by adjusting the yarn-splitting comb device, the filaments are evenly divided into multiple independent fiber bundles according to the felt width and fiber density requirements. The yarn-splitting process is controlled by a motor to adjust the yarn-splitting angle and spacing, ensuring that each fiber bundle is parallel and does not cross. The separated fibers are precisely guided to the yarn-laying station by guide rollers, and a laser positioning system is used to achieve precise control of the fiber bundles' landing points on the conveyor belt, laying a uniform foundation for felt forming. Then, the fiber bundle is three-dimensionally spread on the conveyor belt by a high-frequency vibration device mounted on the swaying head and controlled by the program. Multi-axis linkage technology is used to make the fibers form a three-dimensional interwoven structure in the horizontal, vertical and vertical directions to form the initial felt. An infrared thickness sensor array is integrated to collect the felt thickness data in real time and feed it back to the control system to dynamically adjust the swaying speed and amplitude to ensure that the uniformity of the felt thickness meets the process standards. A multi-stage pressing device is used to progressively thin the felt blanket by adjusting the gap and pressure distribution of the pressing rollers. During the thinning process, the fiber density distribution is monitored simultaneously, and the local density difference is automatically compensated by the pressure feedback system to optimize the fiber arrangement density and weaving efficiency. After thinning, the surface is scanned by a laser flatness detector to accurately press or loosen local protrusions or depressions to ensure that the flatness of the felt blanket surface meets the requirements of subsequent sewing. Employing a multi-axis linkage sewing machine head, the high-speed weaving operation is carried out on the compressed felt. The stitch length, stitch density, and tension are precisely adjusted through a digital control system to form a continuous and stable woven felt structure, enhancing the longitudinal strength and dimensional stability of the felt body. The integrated high-speed camera system and image processing algorithm detect the integrity of the sewing stitches, the consistency of tension, and the quality of thread end processing in real time, automatically marking defective areas and triggering repair procedures. The woven felt blank is transported to the intelligent baking and curing system. The baking curve is optimized by temperature field simulation software. The combined heating method of infrared radiation and hot air circulation is adopted to achieve uniform curing of the resin inside the felt or gradient curing of the fiber binder, ensuring the strength and weather resistance of the felt. The degree of resin curing is monitored in real time by an online infrared spectrometer, and the baking temperature and time parameters are dynamically adjusted to ensure that the degree of curing is precisely controlled within the process window, avoiding performance fluctuations caused by over-baking or under-baking. A combined air-cooling and water-cooling device is used to perform gradient cooling on the cured felt. During the cooling process, temperature gradient control is used to avoid thermal stress inside the felt while maintaining the flatness of the felt surface. After cooling, dynamic compaction is performed by an adjustable pressure roller group to further enhance the structural stability and surface density of the felt. The compaction pressure and speed are adjusted in real time through a closed-loop control system to ensure uniform compaction effect. The multi-blade synchronous longitudinal cutting device is used to cut the felt body with high precision according to the set width. The cutting process is ensured by a laser positioning system to ensure the straightness of the cut. At the same time, the waste edge recycling system is integrated to realize the automatic recycling and reuse of scrap materials. The cut finished felt is rolled up by an automatic winding device. The winding tension is precisely controlled by a motor to avoid deformation of the felt body caused by winding too tightly or too loosely. Finally, the finished product is sealed, labeled and stacked by an automatic packaging line, realizing the full-process automation and intelligent production.

[0024] In one implementation, refer to Figure 1 and Figure 2 A continuous felt manufacturing apparatus for seam edges includes a support platform 1. A concave frame 2 and a guide rod 4 are fixedly connected to the top of the support platform 1. Two rotatable transmission rollers 3 are provided inside the concave frame 2. A driving component is provided on one side of the support platform 1 for rotating the two transmission rollers 3. Two movable seats 5 are slidably connected to the surface of the guide rod 4. A cooling plate 6 is provided on the surface of the movable seat 5. A linkage mechanism 7 is provided between the two cooling plates 6 and the ends of the two guide rods 4. The linkage mechanism 7 includes a fixed plate 71 fixed to the end of the transmission roller 3. A fixed rod 72 is fixedly connected to the surface of the fixed plate 71. A linkage rod 73 is slidably connected to the surface of the fixed rod 72. The end of the linkage rod 73 is fixedly connected to the movable seat 5.

[0025] By adopting this scheme, the continuous seam felt can be intermittently cooled and compacted from top to bottom through the linkage mechanism 7. This method achieves efficient cooling and uniform compaction of the continuous seam felt, avoiding defects such as interlayer debonding, thermal stress cracking, and fiber damage that can easily occur with prolonged cooling and compaction, and further improving the mechanical strength of the felt.

[0026] In practice, the support platform 1 is first installed on the baking and curing side, so that the baked and cured continuous seam felt is led out between the two transmission rollers 3 of the concave frame 2, and then led out between the sliding seats 5 of the guide rod 4, and finally connected to the cutting and rolling equipment. The driving component drives the transmission rollers 3 to rotate, and the linkage mechanism 7 drives the two moving seats 5 to move back and forth alternately upward. When the two moving seats 5 are close to each other, the cooling plate 6 can be attached to the upper and lower surfaces of the continuous seam felt to cool and compact it. When the two moving seats 5 are far apart, the internal cracks, warping or uneven material properties caused by rapid cooling of the continuous seam felt are avoided. In addition, during the process of moving away, more uniform cooling can be achieved by air convection, and the cooling plate 6 can be restored to the best state for secondary cooling and heat dissipation. The transmission roller 3 drives the fixed disk 71 and the fixed rod 72 to rotate. When the fixed rod 72 rotates, it will cause the sliding linkage rod 73 to move up and down reciprocally. Since the linkage rod 73 is fixed on one side of the movable seat 5, the movable seat 5 can be moved up and down reciprocally in sync.

[0027] Additional information: The width of the continuous felt along the seam is less than or equal to the size of the cooling plate 6.

[0028] In one implementation, refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 An expansion mechanism 8 is provided inside the movable seat 5. The expansion mechanism 8 is fixedly connected to the side wall of the cooling plate 6. The expansion mechanism 8 is used to gradually displace and compress the cooling plate 6. The expansion mechanism 8 includes an air bladder 81 fixed inside the movable seat 5. An air inlet pipe 82 and an air vent pipe 84 are fixedly connected to the surface of the air bladder 81. An air injection component 83 is fixedly connected to the end of the air inlet pipe 82. An air jet cover 85 is fixedly connected to the end of the air vent pipe 84. The air jet cover 85 is fixedly connected to the side wall of the movable seat 5. A solenoid valve is provided between the air jet cover 85 and the air vent pipe 84. The air injection component 83 includes two piston cylinders 831 provided on the side wall of the concave frame 2. An air inlet 832 is fixedly connected to the surface of the two piston cylinders 831. A piston rod 833 is slidably connected inside each piston cylinder 831. A cam 835 is attached to the surface of the piston rod 833. The cam 835 is fixed to the end surface of the transmission roller 3. A return spring 834 is sleeved on the surface of the piston rod 833. The return spring 834 is fixed to the end of the piston cylinder 831.

[0029] By employing this approach, the continuous seam felt is cooled and compacted through multiple gradient pressures, resulting in a more compact fusion of the multi-layered felt structure. This avoids the defects that traditional processes, such as excessive fiber compression, breakage, or surface indentation caused by single-stage cooling and compaction, as well as interlayer debonding and thermal stress cracking. This further enhances the mechanical strength, dimensional stability, and environmental resistance of the continuous seam felt.

[0030] In specific operation, under the drive of the expansion mechanism 8 inside the movable seat 5, the cooling plate 6 fixed by the expansion mechanism 8 can be slowly pushed out in three stages. When the air injection component 83 injects air into the air inlet pipe 82 and the air bag 81 for the first time, the cooling plate 6 connected to the air bag 81 can be initially pushed out to apply pressure to the continuous felt. The large-scale air mass inside the felt body is eliminated by low-pressure pre-compression, the irregularity of fiber stacking is initially corrected, the initial porosity is reduced, and the foundation is laid for subsequent compaction. This stage can avoid fiber orientation disorder or local crushing caused by the direct action of high pressure. When the air injection component 83 injects air into the air inlet pipe 82 and the air bag 81 for the second time, after the initial shaping, the residual micropores are further compressed by medium pressure to adjust the contact state of the fiber matrix interface in the continuous felt, promote the wetting and flow of the matrix resin, and reduce the risk of interlayer debonding caused by air retention. When the air injection assembly 83 injects air into the air inlet pipe 82 and the air bag 81 for the last time, the high-pressure shaping achieves the final density control of the felt body, ensuring that the thickness and density uniformity meet the design requirements. At the same time, the internal residual stress is eliminated through the pressure holding process, improving dimensional stability. The gradient pressure design of multi-layer pressure application can avoid density fluctuations caused by alternating "overpressure-underpressure". After the continuous seam felt is cooled and compacted, the air inside the airbag 81 is released through the vent pipe 84, and then the air is evenly sprayed out through the jet hood 85 to further cool the continuous seam felt. The air cooling can also remove a small amount of moisture inside the continuous seam felt. The solenoid valve between the vent pipe 84 and the jet hood 85 can be opened at regular intervals. Air is introduced through the air inlet 832 on the side wall of the piston cylinder 831. Then, the air inside the piston cylinder 831 is compressed and delivered to the air inlet pipe 82 by the piston rod 833 under the pressure of the cam 835. Then, the piston rod 833 is automatically reset by the return spring 834. At this time, the air inlet 832 injects air into the piston cylinder 831 again, and the cam 835 and the transmission roller 3 rotate continuously.

[0031] In addition, one-way valves are provided on the surfaces of the air intake pipe 82 and the air intake port 832. The one-way valves of the air intake pipe 82 and the air intake port 832 are arranged in opposite directions. The one-way valve of the air intake pipe 82 is for one-way air outflow, and the one-way valve of the air intake port 832 is for one-way air inflow.

[0032] In one implementation, refer to Figure 7 , Figure 8 The driving component includes a stepper motor 9 fixed to the side wall of the support platform 1. The output end of the stepper motor 9 is connected to a rhomboid shaft 91 via a flange. A gear 92 is sleeved on the surface of the rhomboid shaft 91. A gear 93 meshes with the surface of the gear 92. The gear 93 is fixedly connected to the other end of the transmission roller 3. An L-shaped connecting frame 94 is rotatably connected to the surface of the transmission roller 3 via a bearing. The L-shaped connecting frame 94 is sleeved on the surface of the rhomboid shaft 91. The gear 93 is rotatably connected within the L-shaped connecting frame 94 via a bearing.

[0033] With this scheme, the diamond shaft 91 drives two opposite gears 92 to rotate, thereby synchronously rotating the two transmission rollers 3 in opposite directions, thus enabling simple compaction and conveying of the continuous felt at the seam edge.

[0034] In actual operation, the stepper motor 9 drives the rhomboid shaft 91 to rotate, and the rhomboid shaft 91 drives the surface gear 1 92 and gear 2 93 to rotate in sequence. Since gear 2 93 is fixed at the end of the transmission roller 3, it can provide a power output source for the transmission roller 3. The L-shaped connecting frame 94 is connected to the transmission roller 3 through a bearing, so it will not affect the rotation effect of the transmission roller 3. At the same time, the L-shaped connecting frame 94 is used to limit gear 1 92 to avoid the problem of gear 1 92 and gear 2 93 disengaging. Furthermore, since the two gears 92 are arranged in opposite directions, when the two gears 92 drive the gear 93 and the transmission roller 3 to rotate, the two transmission rollers 3 rotate in opposite directions.

[0035] Additional explanation: After the stepper motor 9 drives the rhomboid shaft 91 to rotate three times, it needs to pause for a period of time to facilitate the winding motor to wind up the compacted continuous seam felt. After the winding motor has finished winding up the compacted felt, the stepper motor 9 will start working again, at which point the winding motor will pause.

[0036] As a supplementary note, the stepper motor 9 has a self-locking function.

[0037] In one implementation, refer to Figure 9 and Figure 10 A fixing block 21 is fixedly connected to the side wall of the concave frame 2. An adjusting screw 22 is threadedly connected to the inner wall of the fixing block 21. An adjusting frame 23 is rotatably connected to the end of the adjusting screw 22 through a bearing. The adjusting frame 23 is rotatably connected to both ends of the transmission roller 3 through a bearing.

[0038] With this scheme, the adjusting frame 23 is rotatably connected to one of the transmission rollers 3. When the adjusting screw 22 drives the adjusting frame 23 to move up and down for adjustment, the distance between the two transmission rollers 3 can be controlled, thereby better compacting the continuous felt.

[0039] In actual operation, the adjustment frame 23 can be adjusted up and down by rotating the adjusting screw 22 inside the fixed block 21. The adjustment frame 23 can simultaneously drive one of the transmission rollers 3 to be adjusted up and down, thereby controlling the distance between the two transmission rollers 3 so as to adjust according to the thickness of the continuous felt after sewing.

[0040] In addition, one side of the adjustment bracket 23 is used for the end of one of the air injection components 83 to simultaneously adjust the air injection component 83 up and down, so as to prevent the cam 835 from being misaligned with the piston rod 833.

[0041] To provide further explanation, of the two drive rollers 3, one drive roller 3 is rotatably connected to the inside of the concave frame 2 via a bearing, while the other drive roller 3 is slidably connected to the inside of the concave frame 2.

[0042] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
