[0025] The technical solution of the present invention is described below in conjunction with the accompanying drawings and embodiments.

[0026] like Figures 1 to 12As shown, a diaper core production equipment described in the present invention is characterized in that it includes a first feeding mechanism 100, a second feeding mechanism 200, a compound mechanism 300 and a winding mechanism 400, the compound mechanism 300 includes a compound frame 1, and two cloth mechanisms are symmetrically arranged on the compound frame 1, each of the cloth mechanisms includes a roller assembly 2, the roller assembly 2 is rotatably arranged on the compound frame 1, the two groups of roller assemblies 2 are tangentially arranged and located at the same height, and also includes a material discharge box assembly 3, a molecular pump assembly 4, a scraper recovery assembly 5 and a glue spraying assembly 6 arranged around the roller assembly 2, the roller assembly 2 is provided with a vacuum device assembly 7 for adsorbing the polymer material arranged outside the roller assembly 2, and the moving direction of the non-woven fabric is specified to be forward, the material discharge box assembly 3 is arranged on the top of the molecular pump assembly 4, and the material discharge box assembly 3 The polymer material is contained therein, the molecular pump component 4 is arranged above the roller component 2, the scraper recovery component 5 is arranged behind the molecular pump component 4, and the glue spraying component 6 is arranged in front of the molecular pump component 4. The polymer material enters the molecular pump component 4 through the unloading box component 3. Before the molecular pump component 4 lays the polymer material on the non-woven fabric, it first passes through the scraper recovery component 5 to scrape the polymer material flat, so as to ensure that the fabric is uniform. The non-woven fabric is laid on the outer surface of the circumference of the roller component 2, and the molecular pump component 4 lays the polymer material on the top of the non-woven fabric. After the molecular pump component 4 lays the polymer material on the non-woven fabric on the roller component 2, the scraper recovery component 5 will recover the polymer material dropped from the roller component 2 and recycle it back to the unloading box component 3 In the process, the non-woven fabric provided with polymer material is sprayed with glue and shaped by the glue spraying assembly 6 to prevent the polymer material from moving. Two pieces of non-woven fabrics sprayed with glue are pressed together by two roller assemblies 2, so that the polymer material is pressed between the two layers of non-woven fabrics, and then the non-woven fabrics are rolled up. Therefore, the non-woven fabric is wound around the outer surface of the roller assembly 2 before the molecular pump assembly 4, passes through the molecular pump assembly 4 in turn, passes through the glue spraying assembly 6, and finally passes through the two roller assemblies 2 for pressing, and then leaves the surface of the roller assembly 2 for rolling up. The first feeding mechanism 100 and the second feeding mechanism 200 respectively feed non-woven fabrics to the two feeding mechanisms. After the two non-woven fabrics are provided with polymer material and compounded on the compounding mechanism 300, they are rolled up by the rolling mechanism 400.

[0027] Specifically, the first unloading mechanism 100 has the same structure as the second unloading mechanism 200, which includes a unloading frame 101, on which two unloading rollers 102 and a plurality of guide rollers 103 are provided, and a swing arm 104 is also swingably provided on the unloading frame 101, on which a plurality of guide rollers 103 are provided, and the unloading frame 101 is also provided with a row of guide rollers 103 corresponding to the guide rollers 103 on the swing arm 104, and the non-woven fabric is interspersed back and forth between the two rows of guide rollers 103 in turn, and a rotating mechanism 105 is provided at the rotating end of the swing arm 104 for swinging the swing arm 104.

[0028] Specifically, the molecular pump assembly 4 includes a fixed ring 41 fixedly mounted on the composite 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, and 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, and a plurality of through holes 45 are provided on the outer surface of the sleeve 43, and 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, and the non-woven fabric is attached to the outer circumference of the roller assembly 2. The surface of each channel 44 is connected to a plurality of through holes 45, and a partition 46 is arranged in all the through holes 45 to prevent the polymer material from entering the channel 44. The sleeve 43 includes an inner cylinder 43a and an outer cylinder 43b. The inner cylinder 43a is provided with the channel 44, and the through holes 45 penetrate the inner cylinder 43a and the outer cylinder 43b at the same time. The partition 46 is arranged between the outer wall of the inner cylinder 43a and the inner wall of the outer cylinder 43b, so that it is easy to install the partition 46. When installing, the partition 46 is firstly sleeved on the outer periphery of the inner cylinder 43a, and then inserted into the outer cylinder 43b together. 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 with 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.

[0029] Specifically, one of the non-woven fabrics is wider than the other non-woven fabric, and a flange assembly 8 is provided below the two roller assemblies 2 to flange the edge of the wider non-woven fabric to cover the other non-woven fabric, thereby preventing the polymer material from leaking out.

[0030] 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.

[0031] Specifically, the composite frame 1 is provided with a power roller 10 for pulling the non-woven fabric, and the first unloading mechanism 100 is also provided with a power roller 10 for driving the non-woven fabric to move, so as to ensure that the non-woven fabric moves at a uniform speed.

[0032] Specifically, the composite 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.

[0033] 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.

[0034] When the present invention is working, the first feeding mechanism 100 feeds the non-woven fabric to the roller assembly 2, and the second feeding mechanism 200 feeds the non-woven fabric to another roller assembly 2. The non-woven fabric is attached to the outer circumferential surface of the roller assembly 2, and the polymer material flows from the unloading 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 at the position where the pattern sheet 22 is provided with a through hole, the polymer material is adsorbed, and at the position where there is no through hole, the polymer material falls, so that the polymer material arranged on the non-woven fabric corresponds to the pattern of the pattern sheet 22, and the fallen polymer material is recovered by the scraper recovery assembly 5 to the unloading box assembly 3. In the process, the polymer material is adsorbed on the non-woven fabric, and the roller assembly 2 continues to rotate. The non-woven fabric of the polymer material rotates to the position of the glue spraying assembly 6 for glue spraying and fixing. After glue spraying, the two layers of non-woven fabric are attached and pressed between the two roller assemblies 2. After pressing, the flange assembly 8 wraps the wider non-woven fabric around the narrower non-woven fabric, and then presses the two non-woven fabrics at the pushing assembly 9 to flatten them, and then roll them up after flattening. When the material of the first unloading mechanism 100 or the second unloading mechanism 200 starts to be unloaded, the swing arm 104 starts to open slowly, so that the distance between the two rows of guide rollers 103 becomes larger and a longer section of non-woven fabric is stored. When the non-woven fabric on one unloading roller 102 is used up, the swing arm 104 starts to close slowly, shortening the distance between the two rows of guide rollers 103 and releasing the non-woven fabric. In this process, the non-woven fabric is replaced with the other unloading roller 102. In this way, the composite mechanism 300 and the winding mechanism 400 can be ensured to work continuously, thereby ensuring the working efficiency of the entire equipment.
