[0024] Example 1:

[0025] Please see Figures 1-5 This utility model discloses a nonwoven fabric multilayer composite pressing device, comprising a correction component 1, a pressing component 2, a detection component 3, and a cooling component 4. The rear end of the correction component 1 is fixedly connected to the pressing component 2, the rear end of the pressing component 2 is fixedly connected to the detection component 3, and the front end of the pressing component 2 is fixedly connected to the cooling component 4. The correction component 1 further includes a correction frame 11, the rear end of which is fixedly connected to the pressing component 2; guide wheels 12 are rotatably connected to the lower sides of the front and rear ends of the correction frame 11; a first sliding groove 13 is provided at the upper and lower ends of the correction frame 11; a sliding rod 14 is fixedly connected to the middle of the lower end of the correction frame 11; and a motor 15 is fixedly mounted. Connected to the upper left side of the correction frame 11, the motor 15 can drive the positive and negative threaded rods 16 to rotate after starting. When the positive and negative threaded rods 16 rotate, they can drive the two sets of correction rods 17 to move left and right. The positive and negative threaded rods 16 are rotatably connected to the middle of the upper end of the correction frame 11. The left end of the positive and negative threaded rods 16 is fixedly connected to the right end drive shaft of the motor 15. The correction rods 17 are slidably connected to the correction frame 11 through the first sliding groove 13. The threaded groove 18 is provided at the upper end of the correction rods 17. The upper end of the correction rods 17 is threadedly connected to the positive and negative threaded rods 16 through the threaded groove 18. The lower end of the correction rods 17 is slidably connected to the slide rod 14.

[0026] The pressing assembly 2 has a pressing frame 21 whose front end is fixedly connected to the correction frame 11. The second slide groove 22 is located at both ends of the pressing frame 21. The heating steel roller 23 is rotatably connected to the second slide groove 22 in the middle of the pressing frame 21. The electric push rod 24 is fixedly connected to the upper and lower ends of the pressing frame 21. After the two sets of electric push rods 24 are started, they can drive the slide 25 and its upper components to move up or down, so that the pressing roller 26 approaches or moves away from the heating steel roller 23. The slide 25 is slidably connected to the pressing frame 21 through the second slide groove 22. The left and right ends of the pressing roller 26 are rotatably connected to the slide 25.

[0027] The detection assembly 3 includes a detection box 31 fixedly connected to the rear end of the pressing frame 21, a temperature sensor 32 fixedly connected to the right end of the inner wall of the detection box 31, which can detect the temperature inside the detection box 31 after being activated, a defect detection camera 33 fixedly connected to the upper and lower ends of the detection box 31, an infrared thermometer 34 fixedly connected to the right end of the inner wall of the pressing frame 21, which can detect the temperature inside the pressing frame 21 after being activated, a heat insulation plate 35 fixedly connected to the front end of the detection box 31, and a cooling guide roller 36 rotatably connected to the rear side of the inside of the detection box 31 at both ends.

[0028] This utility model provides an improved nonwoven fabric multilayer composite pressing device, the working principle of which is as follows:

[0029] First, when using this device, place it in the work area and then connect it to an external power source to provide the necessary electrical energy for its operation.

[0030] Secondly, when this device is needed, the multi-layer nonwoven fabric can be pulled through the space between the two sets of correction rods 17, then pulled through the hollowed-out groove in the middle of the two sets of heating steel rollers 23, pressing rollers 26 and heat insulation plate 35 into the detection box 31, then through the space between the two sets of cooling guide rollers 36 and out of the rear end of the detection box 31. Then, the motor 15 is started by controlling the display controller 41. After the motor 15 starts, it can drive the positive and negative threaded rods 16 to rotate. When the positive and negative threaded rods 16 rotate, they can drive the two sets of correction rods 17 to move left and right to correct the multi-layer nonwoven fabric, so that the multi-layer nonwoven fabric is in the middle of the correction frame 11 to avoid deviation. Then, the two sets of electric push rods 24 are controlled to start and drive the slide 25 and its upper components to move up or down, so that the pressing roller 26 is close to or away from the heating steel roller 23 to correct the multi-layer nonwoven fabric. The pressing pressure applied to the nonwoven fabric is adjusted, and the heating steel roller 23 and infrared thermometer 34 can be activated simultaneously. After the heating steel roller 23 is activated, it can generate heat and transfer heat to the nonwoven fabric contact interface, causing the adhesive components (low melting point fibers, hot melt adhesive, etc.) at the interface to melt and activate, forming a viscous flow state. This allows the molten adhesive components to flow, penetrate, and mix between the interfaces, tightly pressing the multiple layers of nonwoven fabric together and expelling any trapped air bubbles. After the infrared thermometer 34 is activated, it can detect the temperature of the heating steel roller 23 and send the detected temperature data to the display controller 41 for processing and display. The display controller 41 can then control the temperature of the heating steel roller 23 based on the temperature data to prevent the heating steel roller 23 from emitting too high or too low temperatures that could affect the pressing effect.

[0031] Example 2:

[0032] Please see Figures 1-5 Compared with Embodiment 1, this embodiment of the nonwoven fabric multilayer composite pressing device further includes: a cooling component 4, a display controller 41 fixedly connected to the left end of the pressing frame 21, a negative ion generator 42 fixedly connected to the upper and lower sides of the front end of the pressing frame 21, an air duct 43 fixedly connected to the left end of the negative ion generator 42, a first fan 44 fixedly connected to the front right end of the pressing frame 21, the upper and lower ends of the first fan 44 fixedly connected to the right end of the air duct 43, a cooling diffuser frame 45 fixedly connected to the upper and lower sides of the inner wall of the detection box 31, and a second fan 46 fixedly connected to the middle of the cooling diffuser frame 45.

[0033] In this embodiment:

[0034] When cooling of the nonwoven fabric after pressing is required, the negative ion generator 42 and the first fan 44 can be started via the display controller 41 when the nonwoven fabric is inserted between the pressing frames 21. After the negative ion generator 42 is started, negative ions are generated. After the first fan 44 is started, external air is drawn in and delivered to the negative ion generator 42 through the air duct 43, blowing the negative ions onto the nonwoven fabric for anti-static purposes. At the same time, the defect detection camera 33 and the infrared thermometer 34 can be started. After the defect detection camera 33 is started, the surface of the output nonwoven fabric can be detected. After the infrared thermometer 34 is started, the temperature inside the detection box 31 can be detected. The defect detection camera 33 and infrared thermometer 34 can send the detected images and temperature data to the display controller 41 via a data cable for processing and display. The display controller 41 can display the detected defects on the surface of the nonwoven fabric to alert the staff. The display controller 41 can also control the second fan 46 to start based on the temperature data. After the second fan 46 starts, it can blow external air into the detection box 31 to cool the pressed nonwoven fabric to the specified temperature and quickly remove the heat, so that the molten adhesive layer solidifies and crystallizes, firmly fixing the multi-layer structure together and giving the composite material the final physical form and dimensional stability.

[0035] This utility model provides an improved nonwoven multilayer composite pressing device. This device achieves a triple breakthrough in nonwoven composite production—"zero defects, ultra-low consumption, and full automation"—through electromechanical integrated closed-loop control (correction → pressing → detection → cooling) and innovative negative ion antistatic design. It provides irreplaceable equipment support for high-end nonwoven fields such as medical and filtration.
