Description

Technical Field

[0001] The invention belongs to the field of fabric processing and relates to composite equipment for PE composite fabrics and a use method thereof. Background Art

[0002] In the production process of PE composite fabrics, composite equipment is the key equipment to achieve the bonding between fabric layers. Its performance directly affects the quality and production efficiency of the composite fabrics. At present, most PE composite fabric composite equipment on the market uses pressure rollers to compact and composite the fabrics. In order to improve the composite effect, it is usually necessary to heat the pressure rollers so that the composite layers of the PE fabrics can fit better under the action of heat.

[0003] The pressing roller heating method of existing equipment is mostly electric heating, that is, heating is achieved by setting an electric heating wire inside the pressing roller. This heating method is prone to uneven temperature distribution on the pressing roller surface. The temperature in some areas is too high, which may cause local scorching of the fabric; if the temperature in some areas is insufficient, the composite layer will not fit firmly, affecting the overall quality of the composite fabric. At the same time, the electric heating element is prone to aging and damage after long-term use, and needs to be replaced frequently, which increases the maintenance cost and downtime of the equipment.

[0004] During the operation of threading the fabric into the pressing roller, the upper pressing roller of traditional equipment is fixed in position, and the distance between the upper and lower pressing rollers is small. The operator needs to accurately align one end of the fabric with the gap between the upper and lower pressing rollers. The threading process is time-consuming and labor-intensive. Moreover, the fabric is prone to friction with the edge of the pressing roller when threading, causing wear on the edge of the fabric and affecting the subsequent composite quality. In addition, some equipment uses a simple sliding structure to achieve the movement and adjustment of the upper pressing roller. However, during the movement, the heating medium (such as hot oil) inside the pressing roller is prone to leakage, which not only wastes energy, but also pollutes the equipment and fabric, and even poses a safety hazard. Summary of the Invention

[0005] In view of this, in order to solve the above problems, the present invention provides a composite device for PE composite fabrics and a method for using the same.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] A composite device for PE composite fabrics, comprising two support frames, a plurality of lower pressure rollers being rotatably mounted between the two support frames, a bracket being slidably mounted between the two support frames, and an upper pressure roller cooperating with the lower pressure roller being rotatably mounted on the bracket;

[0008] An oil inlet pipe is provided on one side of one of the support frames, and an oil return pipe is provided on the other side of the support frame. Both the oil inlet pipe and the oil return pipe are connected to the upper pressure roller and the lower pressure roller through pipelines. Hot oil enters the upper pressure roller and the lower pressure roller through the oil inlet pipe and then flows back from the oil return pipe to achieve heating;

[0009] A protective cover is provided on one side of one of the support frames, and multiple gears are rotatably installed in the protective cover. The lower gear is fixedly connected to the lower pressure roller, and the upper gear is clamped to the upper pressure roller through a clamping mechanism. A sealing assembly is provided in the clamping mechanism to prevent oil leakage when the upper pressure roller moves. One of the gears is connected to an external motor and drives the upper and lower pressure rollers to rotate the composite fabric.

[0010] As a further improvement of the above technical solution:

[0011] The bracket includes a No. I mobile frame, a No. II mobile frame and a No. II guide rod. One side of the No. II mobile frame is penetrated and slidably sleeved with a No. II guide rod.

[0012] The clamping mechanism includes a No. 1 gear disc and a No. 2 gear disc. The No. 1 gear disc is fixedly sleeved on the outer wall of the upper pressure roller. A fixed tube is rotatably installed on one side of the protective cover. The No. 2 gear disc and the gear are both fixedly sleeved on the fixed tube.

When the upper pressure roller moves, the fixed rod pushes the sliding rod to open the through hole, thereby realizing oil circuit connectivity.

[0014] One end of the upper pressure roller is provided with a bead, one end of the fixed tube is provided with a groove adapted to the bead, a sealing ring is provided in the groove, and the bead and the sealing ring fit together to enhance the seal.

[0015] It also includes a No. I cutting frame, which is arranged at one end of the two support frames. A No. I knife roller is rotatably installed on the No. I cutting frame, and a No. II knife roller is adjustably installed on the No. I cutting frame. Two No. I cutters are fixed on the outer wall of the No. II knife roller, and a No. I knife groove is opened on the outer wall of the No. I knife roller. The No. I cutter and the No. I knife groove cooperate to cut the edge of the fabric into a serrated shape, thereby reducing the composite stress.

[0016] Two No. I guide rods are fixed on the top of the No. I cutting frame, and a mounting frame is provided on the sliding sleeve of the outer wall of the No. I guide rod. The No. II knife roller is rotatably mounted on one side of the mounting frame. A top plate is fixed on the top of the two No. I guide rods, and a screw is threaded through the top plate. The bottom end of the screw is rotatably connected to the mounting frame, and the height of the No. II knife roller is adjusted by rotating the screw.

[0017] It also includes a No. II cutting mechanism, which includes a No. II cutting frame, which is fixed between two supporting frames. Two sliding frames are adjustably installed on the outer wall of the No. II cutting frame. A positioning roller is rotatably installed on one side of the sliding frame. A No. II cutter is fixed on the outer wall of the positioning roller. A No. II knife groove is opened on the top of the No. II cutting frame. The No. II cutter cooperates with the No. II knife groove to cut the serrated edge of the fabric.

[0018] A No. 1 rotating seat and two No. 2 rotating seats are fixed on the top of the support frame. A plurality of guide rollers are rotatably installed between the No. 1 rotating seat and the No. 2 rotating seat. A cooling pipe is provided on the top of the support frame. One end of the cooling pipe is connected to a blower. After compounding, the fabric is guided to the bottom of the cooling pipe by the guide roller, and the blower cools and shapes it through the cooling pipe.

[0019] A method for using a composite device for PE composite fabrics, applied to the composite device for PE composite fabrics, comprises the following steps:

[0020] S1. Push the bracket to move the upper pressing roller away from the lower pressing roller, pass the fabric between the upper pressing roller and the lower pressing roller, reset the bracket and fix it with the nut ring;

[0021] S2, start the external motor to drive the gear to rotate, driving the upper and lower pressure rollers to rotate and convey the fabric;

[0022] S3. Start the external pump to send hot oil into the upper and lower pressing rollers through the oil inlet pipe. After heating, the fabric is compounded between the upper and lower pressing rollers, and the hot oil flows back through the oil return pipe.

[0023] S4. After compounding, the fabric is cut at the edge by cutting mechanism II and cooled by cooling pipe to complete the processing.

[0024] The beneficial effects of the present invention are:

[0025] 1. The present invention discloses a composite equipment for PE composite fabrics, which heats the upper and lower pressure rollers by circulating hot oil. The hot oil enters the upper and lower pressure rollers through the oil inlet pipe, and then flows back to the oil tank through the oil return pipe to form a cycle. This can effectively soften the composite layer of the PE fabric, allowing the fabric to fit better during the compaction process and improve the composite firmness, and can also avoid damage to the fabric such as burning and deformation caused by excessive temperature. At the same time, compared with traditional electric heating, the circulating heating method has more uniform heat distribution, ensuring consistent composite effect of all parts of the fabric.

[0026] 2. The composite equipment of a PE composite fabric disclosed in the present invention, the clamping mechanism and the sealing assembly cooperate with each other, which can not only realize the transmission connection between the upper pressure roller and the gear, but also effectively prevent hot oil leakage when the transmission connection is disconnected. The No. 1 toothed disc and the No. 2 toothed disc in the clamping mechanism always remain engaged to ensure the transmission of the upper pressure roller. The sealing assembly realizes sealing and oil supply through the misalignment of the through holes on the movable plate and the No. 2 fixed plate, and cooperates with the contact between the edge of the upper pressure roller and the sealing ring in the groove of the fixed pipe. This not only reduces the waste of hot oil and reduces the maintenance cost of the equipment, but also avoids the pollution of equipment components and fabrics caused by oil leakage, and ensures the cleanliness of the production environment. In addition, the upper pressure roller can move with the bracket. When the fabric is inserted, the distance between the upper pressure roller and the lower pressure roller can be increased, which facilitates the smooth passage of the fabric between the upper and lower pressure rollers, reduces the friction between the fabric and the edge of the pressure roller during threading, reduces the possibility of fabric wear, and makes the threading operation of the operator more convenient and efficient.

[0027] 3. The present invention discloses a composite equipment for PE composite fabrics. Cutting mechanism No. 1 first cuts the edge of the fabric into a serrated shape, which can disperse the stress of the fabric during the composite process. After the composite is completed, cutting mechanism No. 2 cuts the serrated edge neatly to ensure the regularity of the fabric edge. At the same time, the cooling pipe cools the fabric in time after cutting. The air blown out by the blower through the cooling pipe can quickly reduce the temperature of the fabric, so that the shape of the composite fabric is quickly fixed. It is not easy to delaminate during subsequent storage or processing, which further improves the processing quality of the fabric.

For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0041] like Figures 1-7 The composite equipment of a PE composite fabric shown in the figure includes two support frames 1,

[0042] Two support frames 1 are arranged in parallel and serve as the installation base of the entire equipment. Between the two support frames 1, multiple lower pressure rollers 8 are rotatably installed through bearings. The number of lower pressure rollers 8 can be set according to actual compounding requirements, generally 3-5, and the spacing between two adjacent lower pressure rollers 8 remains consistent. A bracket 18 is also slidably installed between the two support frames 1, and upper pressure rollers 7 are rotatably installed on the bracket 18 through bearings. The number of upper pressure rollers 7 is the same as that of lower pressure rollers 8, and each upper pressure roller 7 is correspondingly arranged directly above the middle of the two lower pressure rollers 8, forming a matching relationship. When the fabric passes between the corresponding upper pressure roller 7 and lower pressure roller 8, it can be fully compacted and compounded.

[0043] An oil inlet pipe 16 is fixedly mounted on one side of one of the support frames 1. One end of the oil inlet pipe 16 is connected to the outlet of an external pump body. A conventional gear pump can be used for the external pump body. Its operating pressure is maintained at 0.3-0.5 MPa to meet the oil supply demand. The oil inlet pipe 16 is connected to the internal cavities of the multiple upper pressure rollers 7 and lower pressure rollers 8 through branch pipes and rotary joints. The branch pipes can be high-pressure oil pipes with good deformation capabilities. An oil return pipe 17 is fixedly mounted on one side of the other support frame 1. One end of the oil return pipe 17 is connected to the oil tank. The oil return pipe 17 is also connected to the internal cavities of the multiple upper pressure rollers 7 and lower pressure rollers 8 through branch pipes. During operation, the external pump body pumps the hot oil in the oil tank into the interior of the upper pressing roller 7 and the lower pressing roller 8 through the oil inlet pipe 16. After the hot oil flows inside the upper pressing roller 7 and the lower pressing roller 8, it flows back to the oil tank through the return oil pipe 17, forming a circulation. In this way, the surface temperature of the upper pressing roller 7 and the lower pressing roller 8 can be maintained at 80-100°C. This temperature range can effectively soften the composite layer of PE fabric, improve the composite effect, and avoid damage to the fabric due to excessive temperature.

[0044] A protective cover 10 is fixedly installed on one side of one of the support frames 1. The protective cover 10 is made of welded steel plates and can prevent external impurities from entering. At the same time, it prevents operators from touching internal components and causing safety hazards. A plurality of gears 9 are installed in the protective cover 10 through a rotating shaft. Each gear 9 located at the bottom is fixedly connected to one end of the corresponding lower pressure roller 8. The connection method can adopt a flat key connection to ensure stable transmission. Each gear 9 located at the top is clamped with the corresponding upper pressure roller 7 through a clamping mechanism, so that when the upper pressure roller 7 moves with the bracket 18, the gear 9 can maintain a transmission relationship with the upper pressure roller 7. A sealing component is also provided in the clamping mechanism. After the gear 9 is separated from the upper pressure roller 7, the sealing component can seal one end of the upper pressure roller 7 to prevent the internal hot oil of the upper pressure roller 7 from leaking during the movement of the upper pressure roller 7. Multiple gears 9 are meshed with each other, and one of the gears 9 located at the bottom is connected to the output shaft of the external motor through a coupling. The external motor can be a servo motor with a speed adjustment range of 50-200r / min. When the motor is working, it drives all the lower pressure rollers 8 and the upper pressure rollers 7 to rotate synchronously through the meshing transmission of the gears 9, thereby realizing the conveying and compounding of the fabrics.

[0045] A cutting frame (I) 11 is fixedly mounted at one end of the two support frames (1). A blade roller (I) 12 is rotatably mounted on the cutting frame (I) via a bearing. The length of the blade roller (I) is slightly greater than the width of the fabric. A blade roller (II) 13 is adjustably mounted on the cutting frame (I) and arranged parallel to the cutting roller (I). Two blades (I) 24 are fixedly mounted on the outer wall of the blade roller (II). The blades of the blades 24 are serrated, and the spacing between the two blades 24 matches the width of the fabric. The outer wall of the blade roller (I) 12 is provided with two blade grooves (I), the shape of which matches the serrated blades of the blades 24 and the position of which corresponds to the blades 24. When the fabric passes between the blade rollers (I) 12 and (II) 13, the blades 24 engage with the corresponding blade grooves (I), cutting the fabric edges, forming serrated edges. The serrated edge can disperse the stress of the fabric during the subsequent lamination process and reduce wrinkling or cracking of the fabric edge.

[0046] A cutting mechanism No. II is installed on the top of the support frame 1, which is used to perform a secondary cutting on the serrated edge of the composite fabric, remove the excess serrated part, and obtain a fabric with neat edges. A cooling pipe 5 is also fixedly installed on the top of the two support frames 1. The cooling pipe 5 is located on one side of the cutting mechanism No. II. The length of the cooling pipe 5 is adapted to the width of the fabric. A plurality of air outlet holes are evenly opened on the pipe wall. The diameter of the air outlet holes is 3-5mm and the spacing is 10-15mm. One end of the cooling pipe 5 is sealed, and the other end is connected to the air outlet of the blower 6 through a pipe. The blower 6 uses a centrifugal blower with a power of 0.5-1.5kW and an adjustable wind speed. When the composite fabric passes over the cooling pipe 5, the blower 6 blows cold air through the air outlet of the cooling pipe 5 to the surface of the fabric, which can quickly reduce the temperature of the fabric and quickly fix the shape of the composite fabric.

[0047] Two pivoting seats (II) and (I) are fixedly mounted on the top of the support frame 1. Both pivoting seats (II) and (I) are bolted to the support frame 1. Multiple guide rollers 4 are rotatably mounted between the two pivoting seats (II) and (I) via bearings. The number of guide rollers 4 is determined by the fabric's conveying path, typically 2-4. The smooth outer surfaces of the guide rollers 4 minimize wear on the fabric surface. Before entering the subsequent winding mechanism, the fabric is guided by the guide rollers 4, ensuring stable conveying direction and preventing fabric deviation from affecting lamination quality.

[0048] The bracket 18 is composed of a No. 1 movable frame 181, a No. 2 movable frame 183 and a No. 2 guide rod 182. The No. 2 guide rod 182 is fixedly installed between the two support frames 1 and is perpendicular to the support frames 1. A through hole is provided on one side of the No. 2 movable frame 183. The No. 2 guide rod 182 slides through the through hole. Its two ends are respectively fixed to the two support frames 1, so that the No. 1 movable frame 181 can move stably along the length direction of the No. 2 guide rod 182. The upper pressure roller 7 is rotatably installed between the No. 1 movable frame 181 and the No. 2 movable frame 183 through a bearing to ensure that the upper pressure roller 7 can move synchronously with the No. 1 movable frame 181. A stud 14 is provided on one side of the No. 1 movable frame 181. One end of the stud 14 is fixedly welded to one side of the support frame 1. The outer wall of the stud 14 is threaded with a nut ring 15. When the No. I mobile frame 181 needs to be fixed, the nut ring 15 is rotated, and the nut ring 15 moves along the stud 14 and contacts the No. I mobile frame 181, so that the No. I mobile frame 181 is tightly fitted with the support frame 1, thereby achieving the positioning of the No. I mobile frame 181.

[0049] The clamping mechanism includes a No. 1 gear disc 25 and a No. 2 gear disc 34. The No. 1 gear disc 25 is fixedly mounted on the outer wall of one end of the upper pressure roller 7 via a flat key. A fixed tube 26 is rotatably mounted on one side of the protective cover 10 via a bearing. The No. 2 gear disc 34 and the gear 9 are both fixedly mounted on the fixed tube 26 via a flat key. The teeth of the No. 1 gear disc 25 and the No. 2 gear disc 34 are meshed. In this way, when the gear 9 rotates, the No. 2 gear disc 34 and the No. 1 gear disc 25 can drive the upper pressure roller 7 to rotate. When the upper pressure roller 7 moves, the No. 1 gear disc 25 and the No. 2 gear disc 34 are disengaged.

[0050] The sealing assembly includes a No. 2 fixed plate 29, which is fixedly mounted on the inner wall of one end of the upper pressure roller 7. A sliding hole is defined on one side of No. 2 fixed plate 29, through which a sliding rod 30 is slidably mounted. A movable plate 31 is fixedly mounted on one end of the sliding rod 30. No. 1 fixed plate 27 is fixedly mounted on the inner wall of the fixed tube 26, and a fixed rod 28 is fixedly mounted on one side of No. 1 fixed plate 27. The fixed rod 28 is coaxially arranged with the sliding rod 30 and abuts one end of the sliding rod 30. Through holes 33 are defined on one side of the movable plate 31, No. 2 fixed plate 29, and No. 1 fixed plate 27. The through holes 33 on the movable plate 31 and No. 2 fixed plate 29 are offset from each other. A spring 32 (a high-temperature-resistant spring made of Inconel X750) is sheathed on the outer wall of the sliding rod 30. The ends of the spring 32, through spring seats, abut against one side of the No. 2 fixed plate 29 and the outer wall of one end of the sliding rod 30, respectively. When the upper pressure roller 7 moves inward, the fixed rod 28 pushes the sliding rod 30 to move, and the sliding rod 30 drives the movable plate 31 to move, and the spring 32 is compressed. At this time, the through hole 33 on the movable plate 31 and the through hole 33 on the No. Ⅱ fixed plate 29 gradually move away from each other, and the hot oil can enter the interior of the upper pressure roller 7 through the through hole 33; and when the upper pressure roller 7 moves in the opposite direction, the spring 32 resets and pushes the movable plate 31, so that the movable plate 31 and the No. Ⅱ fixed plate 29 are close. Due to the misalignment of the through hole 33, sealing is achieved, effectively preventing oil leakage.

[0051] One end of the upper pressure roller 7 is provided with a bead, the length of which is at least 2 cm. One end of the fixed tube 26 is provided with a groove adapted to the bead, in which a sealing ring can be installed. When the upper pressure roller 7 moves inward, the bead contacts the sealing ring in the groove, further enhancing the sealing effect and reducing the possibility of oil leakage.

[0052] Cutting mechanism II comprises a cutting frame 35, fixedly mounted between the two support frames 1. Two sliding frames 36 are slidably mounted on the outer wall of cutting frame II 35, positioned relative to each other. A positioning roller 38 is rotatably mounted on one side of the sliding frame 36 via a bearing. A fixed sleeve with a cutting blade 39 is mounted on the outer wall of the positioning roller 38. A cutting blade 39 is fixedly mounted on the top of the cutting frame 35, with a cutting blade slot 37 corresponding to the position of the cutting blade 39. A bolt 40 is threaded through the top of the sliding frame 36, the bottom end of which abuts against the top of the cutting frame 35. The spacing between the two cutting blades 39 is adjusted by moving the sliding frame 36 according to the required width of the fabric. Once adjusted, the bolt 40 is tightened, abutting against the cutting frame 35 to secure the sliding frame 36. As the composite fabric passes between the positioning roller 38 and the sliding frame 36, the cutting blade 39 cooperates with the cutting blade slot 37 to neatly cut the fabric's serrated edges.

[0053] Two No. 1 guide rods 20 are fixedly mounted on the top of the No. 1 cutting frame 11. The outer walls of the two No. 1 guide rods 20 are slidably fitted with mounting brackets 19. The No. 2 cutter roller 13 is rotatably mounted on one side of the mounting brackets 19 via bearings. A common top plate 21 is fixedly mounted on the top of the two No. 1 guide rods 20. A screw 22 is threaded through the top of the top plate 21. The bottom end of the screw 22 is rotatably connected to the mounting bracket 19 via a bearing. Rotating the screw 22 drives the mounting bracket 19 up and down along the No. 1 guide rods 20, thereby adjusting the spacing between the No. 2 cutter rollers 13 and No. 1 cutter roller 12 to accommodate the cutting needs of fabrics of varying thicknesses. Once adjusted, the screw 22 cooperates with the threads of the top plate 21 to achieve positioning and can be adjusted to the maximum distance for threading.

[0054] When in use, the cloth and the PE film are pulled between the No. I knife roller 12 and the No. II knife roller 13, and the screw 22 is rotated to drive the mounting frame 19 to move downward. The downward movement of the mounting frame 19 can drive the No. II knife roller 13 to move closer to the No. I knife roller 12. During the approaching process, the No. I cutter 24 and the No. I knife groove 23 are used to cut it, forming a serrated edge;

[0055] After that, it is pulled onto the multiple lower pressing rollers 8 and passed over the three guide rollers 4 on one side. At the same time, the two positioning rollers 38 are pressed against the edge of the cloth. The serrated edge is cut by the No. II cutter 39 and the No. II knife groove 37, and finally fixed on the winding roller.

[0056] Push the bracket 18 to reset and move. The movement of the bracket 18 can move the upper pressure roller 7 to the top of the lower pressure roller 8. When the sliding rod 30 contacts the fixed rod 28, it can push the sliding rod 30 to move inside the upper pressure roller 7, so that the through hole 33 on the movable plate 31 is separated from the through hole 33 on the No. II fixed plate 29, completing the communication of the oil circuit until the No. I gear disc 25 and the No. II gear disc 34 are fully engaged. At this time, the stud 14 passes through one side of the No. I movable bracket 18 and is then locked with the nut ring 15. The external motor is started to drive one of the gears 9 to rotate.
