in the process of producing sanitary pants using the apparatus of the present invention, firstly, the cotton core pulp on the cotton core pulp frame 7 enters the cotton core crusher 101 to crush, the crushed cotton core pulp is absorbed and molded from the outlet through the first pipe 1010 and the second pipe 1011 to the surfaces of the first mesh module 105 and the second mesh module 106 opposite to the large cotton core molding area 1031 and the small cotton core molding area 1041 respectively under the absorption action of the first negative pressure fan 102, at the same time, the molded large cotton core rotates with the first mesh module 105 (the rotation direction is shown by the arrow in fig. 2) to the large cotton core transfer area 1032, and at the same time, the molded small cotton core rotates with the second mesh module 106 (the rotation direction is shown by the arrow in fig. 2) to the small cotton core transfer area 1042, and then, under the action of the blowing force of the first positive pressure fan 1015 and the suction force of the second negative pressure fan 1020, the large cotton core is absorbed to a region of the transfer wheel 107 opposite to the composite cotton core absorption area 1071, and at the same time, under the action of the second positive pressure fan 1020 and the suction force of the second positive pressure fan 1016 is also opposite to the small cotton core transfer area 107; then, with the rotation of the transfer wheel 107 (the rotation direction is shown by the arrow in fig. 2), the large cotton core and the small cotton core are moved to the position of the lower composite cotton core transfer area 1072, in which the second negative pressure fan 1020 is not adsorbed, and the large cotton core falls onto the conveyor belt below the transfer wheel 107 from the transfer wheel 107 due to the self weight, and then the small cotton core falls onto the upper surface of the large cotton core already located on the conveyor belt from the transfer wheel 107 due to the self weight. And conveying the compounded cotton cores to the next working procedure through a conveying belt.

On a conveying belt, the compounded large and small cotton cores are coated by cotton core coating non-woven fabrics, then a guide layer is paved above the small cotton cores, the compounded large and small cotton cores are cut into one piece by a cotton core cutter 10, then a PE bottom film adhered with crotch lifting rubber strings is paved below the cotton core coating non-woven fabrics (at this time, the PE bottom film is sprayed with glue by a first glue spray gun 29 in advance, then the crotch lifting rubber strings on a crotch lifting rubber string material frame 11 are adhered with the PE bottom film), then a surface layer non-woven fabric is paved above the guide layer, and a second glue spray gun 30 is paved on the surface layer non-woven fabrics in advance, then the rubber strings on the rubber string material frame 14 are adhered with the surface layer non-woven fabrics, at this time, the core body is cut into one piece by a core cutter 16, at this time, as shown in fig. 18, the conveying speed of the core body A is V1, the distance between two core bodies A is P1, the core body A is conveyed to a vertical conveying mechanism 205 through a core body transferring mechanism 205, and the core body A is conveyed to a vertical conveying mechanism 205A, and the suction is a vertical suction fan is made to be a horizontal and a vertical suction fan is made to be a vertical suction fan 2053, and the suction fan is made to be a small and the suction fan is made to be a horizontal and a vertical suction fan 2 is made a vertical and a suction fan is made to be a suction type and a suction type is a suction type and a suction type; meanwhile, the central shaft 201 is driven to rotate by a total driving motor, so that the guide disc fixing seat 208 is driven to rotate (the track disc 203 and the cylinder sleeve 204 do not move), the guide disc 207 is driven to rotate, the central shafts 2064 in the eight speed changing mechanisms 206 drive the large connecting rods 2063, the large connecting rods 2063 drive the small connecting rods 2062, the small connecting rods 2062 drive the fixed supporting point shafts 2061, the fixed supporting point shafts 2061 drive the rollers 2057 below the bases A2051 in the eight grabbing mechanisms 205 to roll circumferentially along the edge rolling tracks of the two track discs 203 by taking the central shaft 201 as the central shaft, the bases A2051 drive the hollow rotating shafts 2052 to do circumferential motion by taking the central shaft 201 as the central shaft, and the closed curve guide grooves 2041 on the outer surface of the edge cylinder sleeve 204 do rotary reciprocating motion, so that the vertical core bodies grabbed by the core vertical transfer wheels 17 are changed into horizontal bodies after the adsorption panel 2053 rotates 180 DEG by taking the central shaft 201 as the central shaft, and at the moment, the transmission speed of the core A is V3; the horizontally placed cores A are then transferred onto a conveyor belt by a core horizontal transfer wheel 18, the distance between every two cores A which are horizontally arranged on the conveyor belt is P2, and the conveying speed is V4, wherein V3 is slightly close to V4.

The speeds V2 and V3 can be adjusted in advance by the speed change mechanism 206 for different sizes of products, the adjustment process being as follows:

the adjusting screw 2091 in the guide disc adjusting mechanism 209 is screwed to move the guide disc fixing seat 208 up or down, so as to drive the guide disc 207 to move up and down, and thus drive the mandrel 2064 distributed in the track groove 2071 to move up and down, so that the angle between the large connecting rod 2063 and the small connecting rod 2062 is changed, as the small connecting rod 2062 is rotationally connected with one end of the base A2051 of the grabbing mechanism 205 through the fixed fulcrum shaft 2061, the distance between two adjacent grabbing mechanisms 205 can be changed, the distance is increased to move close to V2, otherwise, the distance is reduced to move close to V3, two areas exist in the motion of one whole rotation of the grabbing mechanism 205, and the speed is periodically increased, namely, the speed-increasing area and the speed-reducing area, so that the core speed V1 with the distance of P1 is matched with the core speed V4 with the longitudinal arrangement and the distance of P2, namely, the speed V1 is perfectly matched with the speed V4 through the speed-changing motion, and the problem of beating (front-back speed difference) when the product is switched after the high-speed rotation.

After the speed changing and transverse changing mechanism 2, the longitudinally arranged and conveyed cores are changed into transversely arranged and conveyed cores, the conveying speed of the cores is reduced to adapt to the condition that the interval between the cores is reduced, then the abdomen rubber band is bonded on the inner non-woven fabric (the abdomen rubber band on the abdomen rubber band material frame 26 is bonded with the inner non-woven fabric by spraying glue on the inner non-woven fabric in advance through a third glue spray gun 31, and an arc rubber band is applied between the outer non-woven fabric and the inner non-woven fabric through an arc rubber band applying mechanism 4; the process of applying the arc-shaped rubber band is as follows:

After the arc-shaped rubber band is manufactured, if two-piece type sanitary trousers are required, firstly spraying glue on the inner layer non-woven fabric and the outer layer non-woven fabric which are applied with the arc-shaped rubber band through a fourth glue spray gun 33, then spreading the inner layer non-woven fabric and the outer layer non-woven fabric on the lower surface of the core body after speed change and transverse change, bonding the inner layer non-woven fabric and the outer layer non-woven fabric, bonding the waistline non-woven fabric bonded with the waistline rubber band (the waistline non-woven fabric is sprayed with glue in advance through a fifth glue spray gun 34, bonding the waistline rubber band on a waistline rubber band frame 19 with the waistline rubber band), cutting off the redundant outer layer non-woven fabrics on two sides of the core body through a rear O cutter 21 after coating the waistline non-woven fabric, and then folding and conveying the product into a folding ear in a folding mechanism 3 after folding and conveying 23, and the folding ear is as follows:

The product which is folded in half and waist-sealed is transported between an upper negative pressure conveyer belt 302 and a lower negative pressure conveyer belt 301 of the folding mechanism 3, the upper surface and the lower surface of the product are pulled apart due to the adsorption action of the upper negative pressure conveyer belt 302 and the lower negative pressure conveyer belt 301, when the product moves between the two side waistband edge inserting units, a driving motor 315 in an inserting plate driving assembly at two sides respectively drives a driving meshing tooth 314 on an output shaft of the driving motor to rotate so as to drive one supporting rod 306 to rotate, and meanwhile, a synchronous belt 309 at two sides respectively drives driven meshing teeth 316 at two sides to rotate so as to respectively drive the other supporting rods 306 at two sides to rotate; meanwhile, the synchronous belts 309 on two sides also respectively drive the first synchronous meshing teeth 318 and the second synchronous meshing teeth 319 on the synchronous shaft 317 to rotate, so as to ensure that the driving motors 315 on two sides can synchronously drive the supporting rods 306 on two sides to rotate, and the rotation directions of the synchronous belts 309 on two sides are shown in fig. 29.

The synchronous rotation of the two support rods 306 at the two sides drives the two rotating plates 307 to synchronously rotate, the two rotating plates 307 then drive the two eccentrically arranged linkage mandrels 308 to synchronously rotate, the two linkage mandrels 308 are rotationally connected with the two ends of one side of the plugboard 304, and then the plugboard 304 at the two sides can do synchronous curve reciprocating motion along with the linkage mandrels 308 at the two sides, so that the plugboard 304 at the two sides continuously inserts the ears extending out of the waist parts at the two sides of the product which are sequentially conveyed between the upper surface and the lower surface of the product; then the air in the product is discharged through the extrusion of the subsequent upper pinch roller belt 312 and the lower pinch roller belt 313, and the product is conveyed to the subsequent process after being flattened.

After the arc-shaped rubber band is manufactured, if three-piece sanitary trousers are required, the outer layer non-woven fabric and the inner layer non-woven fabric with the arc-shaped rubber band are cut into two pieces through the cutter 28, the two non-woven fabrics are respectively guided and pulled apart by the first guide roller 504 and the third guide roller 506 and then separated into preset intervals through the second guide roller 505 and the fourth guide roller 507, then the separated outer layer non-woven fabric and inner layer non-woven fabric are transmitted and tiled to the lower surface of the core body which is changed into a transverse arrangement, the waistline non-woven fabric with the waistline rubber band is adhered (the waistline non-woven fabric is sprayed with glue by the fourth glue spray gun 33 in advance, then the waistline rubber band on the waistline rubber band rack 19 is adhered with the waistline non-woven fabric) is adhered to the upper surface of the core body, the waistline non-woven fabric is wrapped and then conveyed by the foldback conveying 22 and the waistline sealing conveying 23, and finally the product is conveyed into the folding ear mechanism 3, and the folding process of the ear is identical to the process.
