Description

Technical Field

[0001] This invention relates to the field of fabric processing equipment technology, and in particular to a fabric smoothing device for processing grey fabric and its usage method. Background Technology

[0002] During the lamination process, "interlayer differences, equipment precision limitations, and process defects" can occur, leading to shape and structural problems in the fabric. These problems cannot be eliminated naturally and directly affect subsequent processing and the quality of the final product. Therefore, a leveling operation is performed on the composite fabric after lamination. To improve work efficiency, integrated equipment that can simultaneously laminate and level the fabric has emerged on the market. This equipment is specifically designed for the one-time lamination of multi-layer materials (such as the lamination between fabrics made of polyvinyl chloride, raw fabrics, and fabrics made of EPDM rubber). It can complete the lamination and leveling functions at the same time and is widely used in the production of waterproof membranes, composite materials, and functional fabrics.

[0003] Chinese invention patent CN217047860U discloses a pressing device for processing polymer fabrics, including an installation platform and a pressing box. The installation platform has a first unwinding roller and a second unwinding roller on its left side and a take-up roller on its right side. The first unwinding roller is located to the left of the second unwinding roller, and its installation height is greater than that of the second unwinding roller. A glue sprayer is located to the right of the second unwinding roller, with its installation height less than that of the first unwinding roller but greater than that of the second unwinding roller. The glue sprayer is fixedly connected to the installation platform via vertical rods fixed at its four corners. The glue sprayer has an upper nozzle on its upper surface and a lower nozzle on its lower surface. The pressing box is fixedly located in the middle of the upper surface of the installation platform. It has a feed inlet in the middle of its left side and a discharge outlet in the middle of its right side. Strip-shaped holes are located on both sides of the middle of its upper surface. Heaters are arranged sequentially from left to right inside the pressing box. The system includes a pressurizing device and a drying device. Two sets of heaters are symmetrically positioned on the inner top and bottom surfaces of the pressing chamber via support rods. A heating plate is located at the inner end of each heater, forming a heating gap between the two heating plates. The pressurizing device includes an upper pressure roller, a lower pressure roller, and a horizontal plate. Connecting plates are located at both ends of the upper pressure roller. The lower end of the connecting plate is rotatably connected to the upper pressure roller, and the upper end is located outside the pressing chamber through a slotted hole. The horizontal plate is fixedly positioned at the upper end between the two connecting plates. Multiple hydraulic telescopic rods are uniformly fixed between the lower surface and the upper surface of the pressing box. The lower pressure roller is located directly below the upper pressure roller, forming a pressure gap between them. The lower pressure roller is connected to the inner bottom surface of the pressing box through fixed plates that are rotatably set at both ends. There are two sets of air drying devices, which are symmetrically arranged on the inner top and inner bottom surfaces of the pressing box. Each set includes an air drying box and a strip-shaped air outlet. A fan is installed inside the air drying box. The strip-shaped air outlet is located at the inner end of the air drying box and is connected to the fan.

[0004] The existing equipment has a closed internal structure for processing boxes. Multiple layers of fabric need to be manually inserted through the feed inlet, passing through the heating gap, pressurizing gap, and drying area before exiting through the discharge outlet. During this process, the fabric needs to be aligned with components such as the pressure roller and drying trough. This operation is difficult and time-consuming, which not only increases the labor intensity of workers but also reduces the overall processing efficiency of the equipment. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a fabric smoothing device for fabric processing and its usage method.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a fabric flattening device for fabric processing, comprising a base plate, a processing box fixed on the top of the base plate, a processing mechanism for pressing and flattening various fabrics on the processing box, feeding holes through the side walls on both sides of the processing box, a fabric feeding mechanism for transporting composite fabric from one feeding hole to the other feeding hole inside the processing box, a take-up roller rotatably mounted on the base plate, a vertical plate for mounting the take-up roller on the base plate, a take-up motor for driving the take-up roller to rotate on the vertical plate, a fabric feeding mechanism for feeding fabric and an adhesive injection mechanism for applying adhesive to the upper and lower surfaces of the fabric on the base plate.

[0007] By adopting the above technical solution, the fabric feeding mechanism first releases the fabric made of the three materials. Then, the fabric is injected with glue through the adjusting through hole. Next, the glued ends of the three fabrics are sequentially laminated together, and the processing mechanism presses the glued ends of the three fabrics together. Then, the pressed and flattened ends of the three fabrics are installed on the fabric threading mechanism. The pressed and flattened composite fabric is transported from one side feed hole to the other side feed hole. During this process, the processing mechanism flattens and flattens the remaining parts of the three fabrics. Finally, the pressed and flattened part of the three materials is passed through the other side feed hole and wound around the take-up roller. The take-up roller can then be operated to take up the fabric. At the same time, the processing mechanism flattens and flattens the moving fabric. There is no need for manual feeding of the fabric into the processing box, which facilitates the use of the device, reduces time consumption, and helps to improve the overall processing speed of the device.

[0008] Furthermore, adjustment through holes are provided on the side walls of the other two sides of the processing box. The fabric threading mechanism includes a fabric threading assembly and a lifting assembly. The fabric threading assembly includes a first linear module fixed to the side wall of the processing box at the position corresponding to the adjustment through hole, a lower clamping plate fixed to the moving end of the first linear module, a vertical rod fixed to the top of the lower clamping plate, and an upper clamping plate slidably disposed on the vertical rod. The lifting assembly includes a limiting block fixed to the upper end of the vertical rod, a spring fixed between the limiting block and the upper clamping plate, a fixing frame fixed to the upper clamping plate, and a roller rotatably mounted on the fixing frame. The top of the adjusting through hole consists of two inclined surfaces and a horizontal surface. The horizontal surface is located between the two inclined surfaces. The roller is rotatably connected to one of the inclined surfaces. The distance between the two inclined surfaces gradually decreases from top to bottom. The number of lifting assembly groups, the number of sliding through holes, and the number of first linear modules are all equal and their positions correspond one-to-one.

[0009] By adopting the above technical solution, firstly, one end of the pressed and flattened fabric is passed between the lower clamping plate and the upper clamping plate. Then, the first linear module works, causing its moving end to move from one feeding hole to the other feeding hole. This causes the lower clamping plate fixed to the first linear module, the vertical rod connected to the lower clamping plate, the upper clamping plate connected to the vertical rod, the limiting block connected to the vertical rod, the spring connected to the limiting block, the fixing frame connected to the upper clamping plate, and the roller connected to the fixing frame to all move. During this process, the roller first moves from the inclined surface on one side of the adjustment through hole to its horizontal surface. The roller gradually decreases under force, which drives the fixing frame connected to the roller and the upper clamping plate connected to the fixing frame to decrease. The spring is gradually stretched, and finally the upper and lower clamping plates clamp the fabric. Finally, the roller moves from the horizontal surface of the adjustment through hole to the inclined surface on the other side of the adjustment through hole. The spring gradually contracts and returns to its original position, which drives the upper clamping plate connected to the spring to rise and return to its original position. Finally, the upper and lower clamping plates release the fabric, realizing the automatic release and clamping operation of the fabric.

[0010] Furthermore, the processing mechanism includes a pressing and leveling assembly, which includes a lower pressure roller rotatably mounted in one of the feeding holes, a mounting frame slidably disposed in the feeding hole on the same side as the lower pressure roller, an upper pressure roller rotatably mounted in the mounting frame, a pressing motor fixed to the processing box and driving the lower pressure roller to rotate, and a first hydraulic push rod fixed to the top of the processing box. The push rod end of the first hydraulic push rod passes through the top of the processing box and slides in cooperation with the feeding hole. The push rod end of the first hydraulic push rod is fixedly connected to the mounting frame. The processing mechanism also includes an air-cooling assembly for cooling the pressed composite fabric.

[0011] By adopting the above technical solution, the fabrics made of the three materials are placed sequentially on the top of the lower pressure roller. The first hydraulic push rod is operated to extend its end, thereby driving the mounting frame fixed to the end of the first hydraulic push rod and the upper pressure roller connected to the mounting frame to descend until the bottom of the upper pressure roller is pressed against the top layer of fabric. At this time, the pressing motor works and drives the lower pressure roller to rotate, which can drive the fabric to move and perform the flattening and pressing operation.

[0012] Furthermore, the air-cooling assembly includes a fan fixed to the processing box, an air cooler fixed to the processing box, a three-way pipe fixed and connected to the air outlet of the air cooler, and two air blowers respectively fixed to the bottom wall and top wall of the processing box. The other two ends of the three-way pipe extend into the processing box, and the other two ends of the three-way pipe are fixed and connected to the two air blowers respectively. The air outlet of the fan is connected to the air inlet of the air cooler. Multiple air outlet holes are provided through the side walls of the air blowers that are close to each other.

[0013] By adopting the above technical solution, the fan draws in air and discharges it from its outlet into the air cooler. Then, the air cooler discharges it from its outlet into the three-way pipe, and then from the three-way pipe into the blower box. Finally, the air is discharged from the outlet hole, which can cool the fabric passing between the two blower boxes.

[0014] Furthermore, the fabric feeding mechanism includes a fabric feeding assembly, which includes a drive box fixed to the base plate, a turntable that passes through the drive box and is rotatably connected to the drive box, three drive cylinders that all pass through the turntable and are rotatably connected to the turntable, fabric feeding rollers that are detachably connected to the drive cylinders by bolts, a rotary motor fixed to the drive box, a gear fixedly sleeved on the output end of the rotary motor, and a gear ring fixed to the turntable and coaxially arranged with the turntable. The number of drive cylinders is equal to the number of fabric feeding rollers and their positions correspond one-to-one. The three fabric feeding rollers are respectively wound with fabric, namely, fabric made of EPDM rubber, fabric made of polyvinyl chloride, and raw fabric. The raw fabric is located between the EPDM rubber fabric and the polyvinyl chloride fabric. The gear meshes with the gear ring. The fabric feeding mechanism also includes a rotating assembly for driving the three drive cylinders to rotate.

[0015] By adopting the above technical solution, the rotating component drives the three drive cylinders to rotate during operation, which in turn drives the three fabric feeding rollers to rotate synchronously, thereby realizing the operation of feeding three types of fabric simultaneously. In addition, the operation of the rotary motor drives the gear to rotate, which in turn drives the gear ring meshing with the gear and the turntable fixed to the gear to rotate, allowing the three fabric feeding rollers to be rotated sequentially to a position near the top of the base plate, so as to facilitate the disassembly and installation of the fabric feeding rollers and drive cylinders.

[0016] Furthermore, the rotating assembly includes three sprockets respectively fixedly sleeved on three drive cylinders, a chain that meshes with the three sprockets, a mounting plate fixed on the turntable, and a rotating motor fixed on the mounting plate. The output end of the rotating motor passes through the mounting plate and is rotatably connected to the mounting plate. The output end of the rotating motor is fixed to one of the sprockets and coaxially arranged.

[0017] By adopting the above technical solution, the rotating motor drives one of the sprockets to rotate, and with the cooperation of the chain and the other two sprockets, the three drive cylinders can be rotated synchronously.

[0018] Furthermore, the fabric placement mechanism also includes auxiliary components, which include two second linear modules fixed to the top of the base plate, a hollow mounting box with an open top, which is attached to the moving end of each of the two second linear modules, an upper connecting plate fixed to the mounting box, a second hydraulic push rod fixed to the upper connecting plate, a lifting frame with a U-shaped structure that is slidably disposed inside the mounting box, and a sliding plate fixed to the end of the push rod of the second hydraulic push rod. The mounting box has a sliding through hole for the sliding plate to pass through and slide in cooperation with it. The sliding plate is fixed to the lifting frame, and the top of both sides of the lifting frame has a placement groove.

[0019] By adopting the above technical solution, when one of the fabric feeding rollers moves to a position close to the top of the base plate, the second linear module works to move its moving end and move the mounting box fixed to its moving end to the bottom of the fabric feeding roller. Then, the second hydraulic push rod works to retract its push rod end to its minimum length, thereby driving the sliding plate fixed to the push rod end of the second hydraulic push rod and the lifting frame fixed to the sliding plate to rise until the two placement slots on the lifting frame contact the roller bodies at both ends of the fabric feeding roller and provide support for the fabric feeding roller, making it easy to disassemble or install the fabric feeding roller and the drive cylinder.

[0020] Furthermore, the glue injection mechanism is located between the processing box and the drive box. The glue injection mechanism includes a glue injection assembly, which includes a U-shaped support frame fixed to the base plate, two glue injection boxes disposed between the two sides of the support frame, a glue spraying pipe fixed and connected to the glue injection box, a glue delivery pipe fixed and connected to the glue injection box, a storage box fixed to the base plate and equipped with a self-heating function, and a material pump fixed to the storage box. The inlet end of the material pump is connected to the inside of the storage box, and a heating plate is provided inside the storage box. The outlet end of the material pump is connected to one of the glue delivery pipes. The two glue delivery pipes are interconnected. Each glue injection box is equipped with multiple glue spraying pipes. The raw fabric passes through the position between the upper and lower glue spraying pipes.

[0021] By adopting the above technical solution, the raw fabric is passed through the position between the upper and lower glue spraying pipes. The material pump works to extract the hot melt adhesive from the storage box and connect it to the glue delivery pipe through the outlet end of the storage box. Then, the glue is discharged from the glue delivery pipe to another glue delivery pipe connected to it. Subsequently, the two glue delivery pipes discharge into two glue injection boxes respectively. Finally, the glue is sprayed out from the glue spraying pipes on both sides, so that the glue spraying operation can be performed on the upper and lower surfaces of the raw fabric.

[0022] Furthermore, the glue injection mechanism also includes a lifting assembly, which includes two limiting rollers rotatably mounted on the glue injection box, two rotating rollers rotatably mounted on the glue injection box, a lifting frame fixed on the upper glue injection box, a third hydraulic push rod fixed on the support frame, and a telescopic tube fixed and connected to one of the glue delivery pipes. The upper rotating roller is rotatably mounted on the upper glue injection box near its top, and the bottom of the EPDM rubber fabric is in contact with the top of the upper rotating roller. The lower rotating roller is rotatably mounted on the lower glue injection box near its top, and the PVC fabric is in contact with the bottom of the lower rotating roller.

[0023] By adopting the above technical solution, the third hydraulic push rod retracts at its end, which in turn raises the lifting frame and the glue injection box fixed to the lifting frame. This adjusts the distance between the two glue spraying pipes, making it easier for workers to pass the fabric through the space between them. Furthermore, the PVC fabric adheres to the bottom of the lower rotating roller, and the bottom of the EPDM rubber fabric adheres to the top of the upper rotating roller. The raw fabric passes between the two limiting rollers and adheres to them, reducing the friction between the fabric and the glue injection box as the fabric passes through.

[0024] This application also discloses a method for using a fabric smoothing device for greige fabric processing, including the following steps: S1. Operate the fabric feeding mechanism to release the fabric made of the three materials; S2. Operate the glue injection mechanism to inject glue into the upper and lower surfaces of the middle blank fabric. S3. After the glue injection is completed, place the PVC fabric, the raw fabric and the EPDM rubber fabric on the top of the lower pressure roller in sequence, and operate the first hydraulic push rod to lower the upper pressure roller until the upper pressure roller is pressed against the top of the EPDM rubber fabric until it is pressed into a composite fabric. S4. The end of the PVC fabric, the raw fabric, and the EPDM rubber fabric that have been pressed together is installed on the fabric threading mechanism and the fabric threading mechanism is operated to transport the composite material from one side feed hole to the other side feed hole. During the transport of the composite fabric, the processing mechanism presses and flattens the remaining parts of the PVC fabric, the raw fabric, and the EPDM rubber fabric. S5. One end of the PVC fabric, the raw fabric, and the EPDM rubber fabric, which are pressed together, is passed through the feed hole on the other side and wrapped around the take-up roller. The composite fabric is then taken up.

[0025] In summary, the present invention has the following beneficial effects: In this application, through the improvement of the prior art, there is no need for manual passage of the fabric through the processing box, which facilitates the use of the device, reduces time consumption, and helps to improve the overall processing speed of the device.

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] like Figure 1-10As shown in the embodiment of this application, a fabric flattening device for fabric processing is disclosed, including a base plate 1, a fabric threading mechanism 5, a processing mechanism 3, a fabric feeding mechanism 7, and a glue injection mechanism 8. A processing box 2 is fixed to the top of the base plate 1. Feeding holes 4 are provided through the side walls on both sides of the processing box 2, and adjustment through holes 6 are provided through the other two side walls of the processing box 2. The top of the adjustment through hole 6 consists of two inclined surfaces and a horizontal surface, with the horizontal surface located between the two inclined surfaces. The distance between the two inclined surfaces gradually decreases from top to bottom. A take-up roller 10 is rotatably mounted on the base plate 1. A vertical plate for mounting the take-up roller 10 is provided on the base plate 1, and a take-up motor for driving the take-up roller 10 to rotate is provided on the vertical plate. First, the fabric feeding mechanism 7 releases the fabric made of the three materials. Then, the fabric is injected with glue through the adjusting through hole 6. Next, the glued ends of the three fabrics are sequentially laminated together, and the processing mechanism 3 presses the glued ends of the three fabrics together. Then, the pressed and flattened ends of the three fabrics are installed on the fabric threading mechanism 5. The pressed and flattened composite fabric is transported from one side feed hole 4 to the other side feed hole 4. During this process, the processing mechanism 3 flattens and flattens the remaining parts of the three fabrics. Finally, the pressed and flattened part of the three materials is passed through the other side feed hole 4 and wrapped around the take-up roller 10. The take-up roller 10 can then be operated to take up the fabric. At the same time, the processing mechanism 3 flattens and flattens the moving fabric. There is no need for manual feeding of the fabric into the processing box 2, which facilitates the use of the device, reduces time consumption, and helps to improve the overall processing speed of the device.

[0030] A fabric threading mechanism 5 is installed inside the processing box 2. The fabric threading mechanism 5 is used to transport the composite fabric from one side feed hole 4 to the other side feed hole 4. The fabric threading mechanism 5 includes a fabric threading assembly 51 and a lifting assembly 52. ​​The fabric threading assembly 51 includes a first linear module 511, a lower clamping plate 512, a vertical rod 513, and an upper clamping plate 514.

The lower clamping plate 512 is fixed to the moving end of the first linear module 511. The vertical rod 513 is fixed to the top of the lower clamping plate 512, and the upper clamping plate 514 is slidably disposed on the vertical rod 513. The lifting assembly 52 includes a limiting block 521, a spring 522, a fixing frame 523, and a roller 524. The number of lifting assemblies 52, the number of sliding through holes 9, and the number of first linear modules 511 are all equal and their positions correspond one-to-one. The limiting block 521 is fixed to the upper end of the vertical rod 513. The spring 522 is fixed between the limiting block 521 and the upper clamping plate 514, and the fixing frame 523 is fixed to the upper clamping plate 514. The roller 524 is rotatably mounted on the fixing frame 523 and is in rolling connection with one of the inclined surfaces. First, one end of the pressed and flattened fabric is passed between the lower clamping plate 512 and the upper clamping plate 514. Then, the first linear module 511 operates, causing its moving end to move from one feeding hole 4 to the other feeding hole 4. This causes the lower clamping plate 512 fixed to the first linear module 511, the vertical rod 513 connected to the lower clamping plate 512, the upper clamping plate 514 connected to the vertical rod 513, the limiting block 521 connected to the vertical rod 513, the spring 522 connected to the limiting block 521, the fixing frame 523 connected to the upper clamping plate 514, and the roller 524 connected to the fixing frame 523 to all move. During this process, the roller 524 first moves from the adjustment... As the inclined surface on one side of the through hole 6 moves to its horizontal plane, the roller 524 gradually decreases under force, causing the fixed frame 523 connected to the roller 524 and the upper clamping plate 514 connected to the fixed frame 523 to both decrease. The spring 522 is gradually stretched, and finally the upper clamping plate 514 and the lower clamping plate 512 clamp the fabric. Finally, the roller 524 moves from the horizontal plane of the adjustment through hole 6 to the inclined surface on the other side of the adjustment through hole 6. The spring 522 gradually contracts and returns to its original position, causing the upper clamping plate 514 connected to the spring 522 to both rise and return to its original position. Finally, the upper clamping plate 514 and the lower clamping plate 512 release the fabric, realizing the automatic release and clamping operation of the fabric.

[0031] The processing mechanism 3 is mounted on the processing box 2 and is used to press and flatten various fabrics.

The upper pressure roller 313 is rotatably mounted in the mounting frame 312. The pressing motor 314 is fixed to the processing box 2 and drives the lower pressure roller 311 to rotate. The first hydraulic push rod 315 is fixed to the top of the processing box 2. The push rod end of the first hydraulic push rod 315 penetrates the top of the processing box 2 and slides in cooperation with the feeding hole 4. The push rod end of the first hydraulic push rod 315 is fixedly connected to the mounting frame 312. The three types of fabric are placed sequentially on top of the lower pressure roller 311. The first hydraulic push rod 315 is operated to extend its end, which in turn drives the mounting bracket 312, which is fixed to the end of the first hydraulic push rod 315, and the upper pressure roller 313 connected to the mounting bracket 312 to descend until the bottom of the upper pressure roller 313 is in close contact with the top layer of fabric. At this time, the pressing motor 314 works and drives the lower pressure roller 311 to rotate, which can move the fabric and perform the flattening and pressing operation.

[0032] The air-cooling assembly 32 is used to cool the laminated composite fabric. The air-cooling assembly 32 includes a fan 321, an air cooler 322, a three-way pipe 323, and air boxes 324. The fan 321 and the air cooler 322 are both fixed to the processing box 2. The outlet of the fan 321 is connected to the inlet of the air cooler 322, and the three-way pipe 323 is fixed to and connected to the outlet of the air cooler 322. The other two ends of the three-way pipe 323 extend into the processing box 2, and are respectively fixed to and connected to two air boxes 324. Two air boxes 324 are provided, fixed to the inner bottom wall and inner top wall of the processing box 2, respectively. Multiple air outlets are provided through the adjacent side walls of the air boxes 324. The blower 321 draws in air and discharges it from its outlet into the air cooler 322. Then, the air cooler 322 discharges the air into the three-way pipe 323, and then from the three-way pipe 323 into the blower box 324. Finally, the air is discharged from the outlet, thus cooling the fabric that passes between the two blower boxes 324.

The drive box 711 is fixed to the base plate 1, and the turntable 712 is mounted through the drive box 711 and rotatably connected to it. Three drive cylinders 713 are provided, all of which are mounted through the turntable 712 and rotatably connected to it. The fabric feeding rollers 714 are detachably connected to the drive cylinders 713 via bolts. The number of drive cylinders 713 is equal to the number of fabric feeding rollers 714, and their positions correspond one-to-one. Each of the three fabric feeding rollers 714 is wound with fabric: EPDM rubber fabric, PVC fabric, and raw fabric. The raw fabric is positioned between the EPDM rubber fabric and the PVC fabric. The rotary motor 715 is fixed to the drive housing 711. A gear 716 is fixedly mounted on the output end of the rotary motor 715. A gear ring 717 is fixed to the turntable 712 and coaxially arranged with it, with the gear 716 meshing with the gear ring 717. When the rotating assembly 72 operates, it drives the three drive cylinders 713 to rotate, which in turn drives the three fabric feeding rollers 714 to rotate synchronously, thus enabling the simultaneous feeding of the three fabrics. In addition, the operation of the rotary motor 715 drives the gear 716 to rotate, which in turn drives the gear ring 717 meshing with the gear 716 and the turntable 712 fixed to the gear 716 to rotate. This allows the three fabric feeding rollers 714 to be rotated to a position close to the top of the base plate 1 in sequence, so that the fabric feeding rollers 714 and the drive cylinder 713 can be disassembled and installed.

[0034] The rotating assembly 72 drives three drive cylinders 713 to rotate. The rotating assembly 72 includes sprockets 721, chains 722, mounting plates 723, and a rotating motor 724. Three sprockets 721 are provided, each fixedly mounted on one of the three drive cylinders 713. The chains 722 mesh with all three sprockets 721. The mounting plate 723 is fixed to the turntable 712. The rotating motor 724 is fixed to the mounting plate 723, and its output end passes through and is rotatably connected to the mounting plate 723. The output end of the rotating motor 724 is fixed to one of the sprockets 721 and coaxially arranged. When the rotating motor 724 operates, it drives one of the sprockets 721 to rotate. With the cooperation of the chains 722 and the other two sprockets 721, the three drive cylinders 713 can rotate synchronously.

[0035] The auxiliary component 73 includes a second linear module 731, a mounting box 732, an upper connecting plate 733, a second hydraulic push rod 734, a lifting frame 735, and a sliding plate 736. Two second linear modules 731 are provided. Both second linear modules 731 are fixed to the top of the base plate 1. The mounting box 732 is attached to the moving end of each of the two second linear modules 731 and has a hollow structure with an open top. The mounting box 732 has a sliding through hole 9 for the sliding plate 736 to pass through and slide. The upper connecting plate 733 is fixed to the mounting box 732, and the second hydraulic push rod 734 is fixed to the upper connecting plate 733. The lifting frame 735 is slidably disposed within the mounting box 732 and has a U-shaped structure. Placement slots are provided on the top of both sides of the lifting frame 735. The sliding plate 736 is fixed to the push rod end of the second hydraulic push rod 734, and the sliding plate 736 is fixed to the lifting frame 735. When one of the fabric feeding rollers 714 moves to a position close to the top of the base plate 1, the second linear module 731 operates to move its moving end and moves the mounting box 732 fixed to its moving end to below the fabric feeding roller 714. Then, the second hydraulic push rod 734 operates to retract its push rod end to its minimum length, thereby driving the sliding plate 736 fixed to the push rod end of the second hydraulic push rod 734 and the lifting frame 735 fixed to the sliding plate 736 to rise until the two placement slots on the lifting frame 735 contact the roller bodies at both ends of the fabric feeding roller 714 and provide support for the fabric feeding roller 714, making it easy to disassemble or install the fabric feeding roller 714 and the drive cylinder 713.

[0036] The glue-applying mechanism 8 is mounted on the base plate 1 and located between the processing box 2 and the drive box 711. The glue-applying mechanism 8 is used to apply glue to the upper and lower surfaces of the fabric. The glue-applying mechanism 8 includes a glue-applying component 81 and a glue-applying assembly 81. The glue-applying assembly 81 includes a support frame 811, a glue-applying box 812, a glue-spraying pipe 813, a glue-transferring pipe 814, a storage box 815, and a material pump 816. The support frame 811 is fixed to the base plate 1 and has a U-shaped structure. Two glue-applying boxes 812 are provided. Both glue-applying boxes 812 are located between the two sides of the support frame 811. The glue-spraying pipes 813 are fixed and connected to the glue-applying boxes 812. Each glue-applying box 812 has multiple glue-spraying pipes 813, with the raw fabric passing through the space between the upper and lower glue-spraying pipes 813. The glue delivery pipe 814 is fixed and connected to the glue injection box 812. The two glue delivery pipes 814 are interconnected. The storage box 815 is fixed to the base plate 1 and has a self-heating function. The storage box 815 is equipped with a heating plate, and the material pump 816 is fixed to the storage box 815. The inlet end of the material pump 816 is connected to the inside of the storage box 815, and the outlet end of the material pump 816 is connected to one of the glue delivery pipes 814. The raw fabric is passed through the position between the upper and lower glue spraying pipes 813. The material pump 816 operates to extract the hot melt glue from the storage box 815 and discharge it through the outlet end of the storage box 815 into the glue delivery pipe 814. Then, the glue is discharged from the storage box 814 into the other glue delivery pipe 814 connected to it. Subsequently, the two glue delivery pipes 814 discharge the glue into the two glue injection boxes 812 respectively. Finally, the glue is sprayed out from the two glue spraying pipes 813, which can perform glue spraying operation on the upper and lower surfaces of the raw fabric.

[0037] The lifting assembly 82 includes two limiting rollers 821, two rotating rollers 822, a lifting frame 823, a third hydraulic push rod 824, and a telescopic tube 825. Two limiting rollers 821 are rotatably mounted on the glue injection tank 812. Two rotating rollers 822 are also rotatably mounted on the glue injection tank 812. The upper rotating roller 822 is rotatably mounted near the top of the upper glue injection tank 812. The bottom of the EPDM rubber fabric is in contact with the top of the upper rotating roller 822, and the lower rotating roller 822 is rotatably mounted near the top of the lower glue injection tank 812. The bottom of the PVC fabric is in contact with the lower rotating roller 822. The lifting frame 823 is fixed to the upper glue injection tank 812, the third hydraulic push rod 824 is fixed to the support frame 811, and the telescopic tube 825 is fixed and connected to one of the glue delivery tubes 814. The third hydraulic push rod 824 retracts its end, causing the lifting frame 823 and the glue injection box 812 fixed to the lifting frame 823 to rise. This adjusts the distance between the two glue spraying pipes 813, making it easier for workers to pass the fabric through the space between the two glue spraying pipes 813. In addition, the PVC fabric is in contact with the bottom of the lower rotating roller 822, and the bottom of the EPDM rubber fabric is in contact with the top of the upper rotating roller 822. The raw fabric passes between the two limiting rollers 821 and is in contact with them, reducing the friction between the fabric and the glue injection box 812 when the fabric passes through the glue injection box 812.

[0038] This application also discloses a method for using a fabric smoothing device for greige fabric processing, including the following steps: S1. Operate the fabric feeding mechanism 7 to release the fabric made of the three materials; S2. Operate the glue injection mechanism 8 to inject glue into the upper and lower surfaces of the middle blank cloth. S3. After the glue injection is completed, the PVC fabric, the raw fabric and the EPDM rubber fabric are placed on the top of the lower pressure roller 311 in sequence, and the first hydraulic push rod 315 is operated to make the upper pressure roller 313 descend until the upper pressure roller 313 is pressed against the top of the EPDM rubber fabric until it is pressed into a composite fabric. S4. The end of the PVC fabric, the raw fabric, and the EPDM rubber fabric that have been pressed together is installed on the fabric threading mechanism 5 and the fabric threading mechanism 5 is operated to transport the composite material from one side feed hole 4 to the other side feed hole 4. During the transport of the composite fabric, the processing mechanism 3 presses and flattens the remaining parts of the PVC fabric, the raw fabric, and the EPDM rubber fabric. S5. One end of the PVC fabric, the raw fabric, and the EPDM rubber fabric, which are pressed together, is passed through the feed hole 4 on the other side and wrapped around the take-up roller 10. The composite fabric is then taken up.
