[0026] Specifically, the molecular pump assembly 4 includes a fixed ring 41 fixedly mounted on the frame 1, a rotating shaft 42 is rotatably connected to the fixed ring 41, and the rotating shaft 42 is driven by a driving mechanism to rotate. A sleeve 43 is fixedly connected to one end of the rotating shaft 42, and a plurality of channels 44 that are independent of each other and open toward the fixed ring 41 are provided inside the sleeve 43. A plurality of through holes 45 are provided on the outer surface of the sleeve 43. The discharge port of the unloading box assembly 3 is directly opposite to the through holes 45, and the sleeve 43 is almost tangent to the roller assembly 2. The non-woven fabric is attached to the outer circumference of the roller assembly 2. Each of the channels 44 is connected to a plurality of through holes 45. All the through holes 45 are provided with a partition 46 to prevent the polymer material from entering the channels 44. The sleeve 43 includes an inner tube 43a and an outer tube 43b. The inner tube 43a is provided with the channels 44. The through holes 45 penetrate the inner tube 43a and the outer tube 43b at the same time. The partition 46 is provided between the outer wall of the inner tube 43a and the inner wall of the outer tube 43b. This facilitates the installation of the partition 46. When installing, the partition 46 is first sleeved on the outer periphery of the inner tube 43a and then inserted into the outer tube 43b. The rotating shaft 42 is provided with a synchronous wheel 47 for driving the rotating shaft 42 to rotate, thereby driving the sleeve 43 to rotate. The fixing ring 41 is provided with a negative pressure chamber 41a and a positive pressure chamber 41b, and the end of the sleeve 43 cooperates with the end of the fixing ring 41 so that the negative pressure chamber 41a and the positive pressure chamber 41b are respectively connected to different channels 44, and the negative pressure chamber 41a is arc-shaped, and the negative pressure chamber 41a is connected to multiple channels 44 at the same time. The negative pressure chamber 41a is connected to the through hole 45 through the corresponding channel 44, and the range of the negative pressure chamber 41a extends from the discharge port of the discharge box assembly 3 to the position where the sleeve 43 is tangent to the roller assembly 2, so as to ensure that the polymer material discharged from the discharge box assembly 3 can be smoothly delivered to the non-woven fabric on the outer surface of the roller assembly 2 without falling. The positive pressure chamber 41b is connected to the corresponding through hole 45 below the sleeve 43 through the corresponding channel 44. The positive pressure chamber 41b is only connected to one of the channels 44, so that the air pressure is high and the polymer material in the through hole 45 can be completely blown clean to ensure uniform fabrication. The negative pressure chamber 41a is connected to the negative pressure fan, and the positive pressure chamber 41b is connected to the air compressor. A cover body 48 is provided outside the negative pressure chamber 41a, and the cover body 48 is connected to the negative pressure fan.
[0027] Specifically, one of the non-woven fabrics is wider than the other non-woven fabric, and a flanging assembly 8 is provided under the two roller assemblies 2 to flanging the edge of the wider non-woven fabric to cover the other non-woven fabric, thereby preventing the polymer material from leaking out.
[0028] Specifically, a pushing assembly 9 is provided in front of the flanging assembly 8 to flatten the flanging non-woven fabric, thereby preventing the polymer material from falling off.
[0029] Specifically, the frame 1 is further provided with a power roller 10 for pulling the non-woven fabric, so as to ensure that the non-woven fabric moves at a uniform speed.
[0030] Specifically, the frame 1 is further provided with a deviation correcting device 11, and the nonwoven fabric is corrected by the deviation correcting device 11 before entering the drum assembly 2 and then laid.
[0031] Specifically, the roller assembly 2 includes a roller-shaped module body 21, and a patterned sheet 22 that can be detachably mounted on the circumferential outer surface of the module body 21. A grid 23 is fixedly mounted inside the module body 21. The grid 23 has through holes that pass through the upper and lower parts, and the patterned sheet 22 also has through holes that pass through the upper and lower parts. The grid 23 is arranged at the bottom of the patterned sheet 22 to support the patterned sheet 22. The grid 23 is a circular arc surface. The patterned sheet 22 is mounted on the module body 21 by bolts so that the patterned sheet 22 fits the grid 23. The module body 21 is further provided with the vacuum device assembly 7, which includes a vacuum chamber 71. The outlet of the vacuum chamber 71 is arc-shaped, and its range covers the position corresponding to the molecular pump assembly 4 to the tangent position of the two roller assemblies 2. The vacuum chamber 71 is connected to a negative pressure fan or a vacuum pump. The vacuum chamber 71 is arranged inside the grid 23. The vacuum chamber 71 is fixed, and the module body 21 rotates around the vacuum chamber 71. The outer end of the vacuum chamber 71 is connected to the through hole of the grid 23. The non-woven fabric is attached to the top of the patterned sheet 22. When the polymer material is arranged on the top of the non-woven fabric, the vacuum chamber 71 passes through the grid 23 and is connected to the patterned sheet 22. Therefore, the non-woven fabric corresponding to the through hole position on the patterned sheet 22 can absorb the polymer material, and the polymer material on the non-woven fabric without the through hole position will fall off and finally be recovered by the scraper recovery assembly 5.
[0032] When the present invention is working, the non-woven fabric is attached to the outer surface of the circumference of the roller assembly 2, and the polymer material is discharged from the material box assembly 3 into the through hole 45 of the sleeve 43. At this time, the through hole 45 is connected to the negative pressure chamber 41a, so the polymer material is adsorbed in the through hole 45, and the sleeve 43 continues to rotate. When the channel 44 corresponding to the through hole 45 with the polymer material rotates to the positive pressure chamber 41b, the polymer material in the through hole 45 is blown to the top surface of the non-woven fabric, and the polymer material is adsorbed at the position where the through hole is provided on the pattern sheet 22, and the polymer material falls at the position where there is no through hole, so that The polymer material arranged on the non-woven fabric corresponds to the pattern of the patterned sheet 22. The fallen polymer material is recovered by the scraper recovery component 5 into the feed box component 3. The polymer material is adsorbed on the non-woven fabric. The roller component 2 continues to rotate, and the non-woven fabric of the polymer material is rotated to the position of the glue spraying component 6 for glue spraying and fixing. After glue spraying, the two layers of non-woven fabric are attached and pressed between the two roller components 2. After pressing, the flanging component 8 wraps the wider non-woven fabric with the flanging around the narrower non-woven fabric, and then the pushing component 9 is pressed to flatten the two non-woven fabrics, and then rolled up after flattening.
