Description

Technical Field

[0001] This application relates to the field of nonwoven fabric processing, and in particular to a high-strength nonwoven fabric composite device. Background Technology

[0002] Nonwoven fabric hot melt lamination is a process that uses hot melt adhesive to bond multiple layers of substrates together. It is widely used in medical protective clothing, masks, filter materials and other fields. The process involves first unwinding multiple layers of substrates simultaneously using an unwinding machine, then applying hot melt adhesive to the surface of the substrates, and finally pressing the material with hot rollers to ensure that the adhesive layer fully penetrates the pores of the nonwoven fabric fibers, thus completing the lamination process.

[0003] However, during the implementation of the relevant technical solutions, at least the following technical problems were found: When nonwoven fabrics are laminated, hot press rollers are generally moved down to a suitable position to hot press nonwoven fabrics of different thicknesses so that multiple layers of nonwoven fabrics can be pressed together. However, if wrinkles appear in the multiple layers of nonwoven fabrics before hot pressing, it will cause delamination and deformation during hot pressing, and the edges may be misaligned, affecting the lamination effect. Utility Model Content

Detailed Implementation

[0018] This application discloses a high-strength nonwoven fabric composite device. The movable part 40 drives the movable seat 30 to move downward, so that the hot pressing roller 51 and the flattening roller 52 can contact the top of nonwoven fabrics of different thicknesses. The engagement of the sprocket 532 and the chain 533 can drive the hot pressing roller 51 and the flattening roller 52 to rotate synchronously. The flattening roller 52 first flattens the nonwoven fabric, and then the hot pressing roller 51 presses it together, preventing the nonwoven fabric from delamination and deformation due to wrinkles during hot pressing, which would affect the quality of the composite.

[0019] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0020] Please refer to Figure 1 and Figure 2 This embodiment provides a high-strength nonwoven fabric composite device, including a base 10. A fixed seat 20 is provided on the top of the base 10. Slide grooves 21 are provided on both sides of the fixed seat 20. A movable seat 30 is slidably connected between the two slide grooves 21. A moving component 40 is provided on the top of the fixed seat 20 to drive the movable seat 30 to move. A composite mechanism 50 is provided at the bottom of the movable seat 30. The composite mechanism 50 includes a hot press roller 51, a flattening roller 52, a transmission component 53, and a cleaning component 54. The hot press roller 51 is rotatably connected to the bottom of the movable seat 30. A support roller is provided at the bottom of the hot press roller 51. The flattening roller 52 is rotatably connected to one side of the hot press roller 51, and flattening textures are provided on the flattening roller 52. The transmission component... 53 is located inside the movable seat 30, and the transmission component 53 is used to drive the hot pressing roller 51 and the flattening roller 52 to rotate. The transmission component 53 can be two drive motors to drive the hot pressing roller 51 and the flattening roller 52 to rotate. The hot pressing roller 51 and the flattening roller 52 are fixed at the bottom of the movable seat 30. The moving part 40 can be a hydraulic rod. The hydraulic rod drives the movable seat 30 to move down to a suitable position, so that the hot pressing roller 51 applies a certain pressure to the non-woven fabric and the support roller at the bottom. At this time, the flattening texture at the bottom of the flattening roller 52 contacts the top of the non-woven fabric, so that the rotation of the flattening roller 52 first flattens the wrinkles on the surface of the non-woven fabric, and then the hot pressing roller 51 is used to press the non-woven fabric together, so that the multiple layers of non-woven fabric are laminated together.

[0021] Please refer to Figure 1 , Figure 2 and Figure 3The movable seat 30 has an internal cavity. The transmission assembly 53 includes a drive motor 531, sprockets 532, and a chain 533. The drive motor 531 is mounted on the outside of the movable seat 30, and its output shaft is fixedly connected to the hot press roller 51. Two sprockets 532 are respectively located on the output shaft of the drive motor 531 and at one end of the flattening roller 52 that extends into the cavity. The chain 533 is meshed with the outside of the two sprockets 532. The output shaft of the drive motor 531 drives the hot press roller 51 inside the movable seat 30 to rotate, pressing the nonwoven fabric. The rotation of the sprockets 532 on the output shaft of the drive motor 531 drives the chain 533 meshing with it to rotate, causing the chain 533 to drive the sprocket 532 on the other side to rotate. This causes the scraper 542 to drive the flattening roller 52 to rotate, flattening the surface of the nonwoven fabric before pressing, so that deformation and delamination will not occur due to wrinkles during pressing. This improves the hot melt bonding effect.

[0022] Please refer to Figure 1 and Figure 2 On the other side of the hot press roller 51, a cutting assembly 60 for cutting the nonwoven fabric on both sides is provided. The cutting assembly 60 includes a connecting rod 61, a movable ring 62, a cutting blade 63, and an adjusting bolt 64. The two connecting rods 61 are respectively located on both sides of the fixed base 20. The movable ring 62 is slidably connected to the outside of the connecting rod 61. The cutting blade 63 is located at the bottom of the movable ring 62. The adjusting bolt 64 is threadedly connected to the outside of the movable ring 62. One end of the adjusting bolt 64 is in contact with the outside of the connecting rod 61. By sliding the movable ring 62 on the connecting rod 61, the position of the bottom cutting blade 63 can be changed. The rotation of the adjusting bolt 64 contacts the connecting rod 61, fixing the position of the cutting blade 63. This allows the cutting blade 63 to cut the misaligned position of the side when errors occur during unwinding or misalignment occurs during transmission of the multi-layer nonwoven fabric, thereby improving the composite effect of the multi-layer nonwoven fabric.

[0023] Please refer to Figure 1 , Figure 2 and Figure 4A cleaning assembly 54 is provided between the hot press roller 51 and the cutting assembly 60. The cleaning assembly 54 includes a cleaning seat 541, a scraper 542, a dust suction pipe 543, and a storage box 544. The cleaning seat 541 is located on the outside of the hot press roller 51, and the scraper 542 is located inside the cleaning seat 541, with one end of the scraper 542 in contact with the outside of the hot press roller 51. The storage box 544 is located on the top of the movable seat 30, and the dust suction pipe 543 is located at the bottom of the storage box 544, communicating with the inside of the cleaning seat 541. The hot press roller 51 heats and presses... The surface of the nonwoven fabric is melted, causing it to adhere to the outside of the hot press roller 51. The scraper 542 inside the cleaning seat 541 comes into contact with the hot press roller 51, and the scraper 542 cleans the impurities adhering to the outside as the hot press roller 51 rotates. After the nonwoven fabric impurities are scraped and collected in the cleaning seat 541, the storage box 544 generates negative pressure, causing the dust suction pipe 543 to absorb the nonwoven fabric waste inside the cleaning seat 541. The waste is collected together and processed centrally, which also prevents the impurities adhering to the hot press roller 51 from affecting the hot pressing operation and improves the quality of composite processing.

[0024] The functional principle of this application can be explained through the following methods:

[0025] In use, after the multi-layer nonwoven fabric substrate is coated with adhesive, it is fed into the fixed seat 20. The moving part 40 is activated, and according to the actual thickness of the substrate, it moves the movable seat 30 down into the two grooves 21 to a suitable position. This causes the hot press roller 51 to exert pressure on the nonwoven fabric and the bottom support roller. At this time, the flattening roller 52 at the bottom of the movable seat 30 contacts the top of the nonwoven fabric. The drive motor 531 is then activated, causing its output shaft to rotate the hot press roller 51. The output shaft of the drive motor 531 also rotates the outer sprocket 532, which in turn rotates the chain 533 meshing with it. The chain 533 then rotates the other inner sprocket 532, causing both sprockets 532 to rotate synchronously. The sprockets 532 then rotate the flattening roller 52. When the nonwoven fabric is fed into the bottom of the movable seat 30, the nonwoven fabric... The top of the fabric first contacts the flattening roller 52, causing the rotation of the flattening roller 52 to flatten the nonwoven fabric. After flattening, it contacts the hot pressing roller 51, causing the hot pressing roller 51 to heat-press the multi-layer nonwoven fabric. The rotation of the hot pressing roller 51 causes the scraper 542 in contact with it to clean the outside of the hot pressing roller 51, causing the scraped nonwoven fabric waste to fall into the cleaning seat 541. Then, it is input into the storage box 544 through the dust suction pipe 543 for centralized processing. Rotating the adjusting bolt 64 on the movable ring 62 releases the contact between the adjusting bolt 64 and the connecting rod 61, allowing the movable ring 62 to move on the connecting rod 61. This allows the two movable rings 62 to move to a suitable position on the side of the nonwoven fabric. Finally, tightening the adjusting bolt 64 fixes the position of the cutting blade 63, allowing the two cutting blades 63 to cut the nonwoven fabric with misaligned sides, improving the composite effect.

Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
