The working principle of the production device of the sanitary pants in the embodiment is as follows:

in the process of producing sanitary pants by using the device of the present invention, firstly, the cotton core wood pulp on the cotton core wood pulp rack 7 enters the cotton core crusher 101 to be crushed, the crushed cotton core wood pulp is adsorbed and molded on the surfaces of the first reticular module 105 and the second reticular module 106 opposite to the large cotton core molding area 1031 and the small cotton core molding area 1041 through the first pipeline 1010 and the second pipeline 1011 from the outlet respectively under the adsorption action of the first negative pressure fan 102, the molded large cotton core rotates (the rotation direction is shown by the arrow in fig. 2) along with the first reticular module 105 to the large cotton core transfer area 1032, meanwhile, the molded small cotton core rotates (the rotation direction is shown by the arrow in fig. 2) along with the second reticular module 106 to the small cotton core transfer area 1042, then, under the blowing force of the first positive pressure fan and the suction force of the second positive pressure fan 1020, the large cotton core is adsorbed and molded on the area 1015 opposite to the composite cotton core adsorption area 1071 of the transfer wheel 107, meanwhile, under the blowing force of the second positive pressure fan 1016 and the suction force of the second negative pressure fan 1020, the small cotton cores are also transferred to the area of the transfer wheel 107 opposite to the composite cotton core adsorption area 1071; then, as the transfer wheel 107 rotates (the rotation direction is shown by an arrow in fig. 2), the large cotton core and the small cotton core are carried to the position of the composite cotton core transfer area 1072 below, the area has no adsorption effect of the second negative pressure fan 1020, the large cotton core firstly falls onto the conveying belt below the transfer wheel 107 from the transfer wheel 107 due to the self gravity, and then the small cotton core falls onto the upper surface of the large cotton core on the conveying belt from the transfer wheel 107 due to the self gravity. The cotton cores with the composite size are conveyed to the next working procedure through a conveying belt.

On a conveying belt, the large and small cotton cores after being compounded are coated by cotton core coated non-woven fabrics, then a flow guide layer is laid above the small cotton cores, the large and small cotton cores after being compounded are cut into one by a cotton core cutter 10, then a PE bottom film adhered with a crotch lifting rubber band is laid below the cotton core coated non-woven fabrics (glue is sprayed on the PE bottom film by a first glue spray gun 29 in advance, then the crotch lifting rubber band on a crotch lifting rubber band rack 11 is adhered with the PE bottom film), then a surface layer non-woven fabric is laid above the flow guide layer, a protection non-woven fabric adhered with a protection rubber band is laid on the surface layer non-woven fabric (glue is sprayed on the protection non-woven fabric by a second glue spray gun 30 in advance, then the protection rubber band on a protection rubber band rack 14 is adhered with the protection rubber band rack), a core body is formed at the moment, then the core body is cut into one by a core body cutter 16, at the moment, as shown in figure 18, the transmission speed of the core body A is V35, the distance between every two core bodies A is P1, the core bodies A are transferred to a grabbing mechanism 205 in the speed-changing transverse conveying device 2 through a core body vertical transfer wheel 17, when the grabbing mechanism 205 grabs the core bodies on the core body vertical transfer wheel 17, a fan adsorbs the hollow wind cabin to generate negative pressure, the core bodies A on an adsorption panel 2053 are adsorbed through holes on the adsorption panel 2053, at the moment, the transmission speed of the core bodies A is V2, and V2 is slightly close to V1; meanwhile, the central shaft 201 is driven by the main driving motor to rotate, so as to drive the guide disc fixing seat 208 to rotate (the track disc 203 and the cylindrical sleeve 204 are not moved), the guide plate 207 rotates, 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 fulcrum shafts 2061, and the fixed fulcrum shafts 2061 drive the rollers 2057 below the grabbing bases 2051 in the eight grabbing mechanisms 205 to circumferentially roll along the edge rolling tracks of the two track plates 203 by taking the central shaft 201 as a central shaft, the grabbing bases 2051 drive the hollow rotating shafts 2052 to circumferentially move by taking the central shaft 201 as a central shaft, and to rotationally reciprocate along the closed curve guide grooves 2041 on the outer surface of the cylindrical sleeve 204, so that after the adsorption panel 2053 rotates 180 degrees by taking the central shaft 201 as a central shaft, the vertically placed core body grabbed from the core body vertical transfer wheel 17 is changed into a horizontally placed core body, and at the moment, the transmission speed of the core body A is V3; the transversely laid cores a are then transferred onto a conveyor belt by means of a core transverse transfer wheel 18, the spacing between two cores a arranged transversely on the conveyor belt being P2, the transport speed being V4, V3 being slightly closer to V4.

For different sizes of products, the speeds V2 and V3 can be adjusted in advance by the speed change mechanism 206 as follows:

screwing the adjusting screw 2091 in the guide disc adjusting mechanism 209 to push up or move down the guide disc fixing seat 208, driving the guide disc 207 to move up and down, thereby driving the spindle 2064 distributed in the track groove 2071 to move up and down, thereby changing the angle between the large connecting rod 2063 and the small connecting rod 2062, because the small connecting rod 2062 is rotatably connected to one end of the grabbing base 2051 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 be close to V2 to move, otherwise, the distance is decreased to be close to V3 to move, thereby forming that two regions exist in the movement of the grabbing mechanism 205 rotating for a whole circle, and the regions are periodically increased and decreased, namely, an acceleration region and a deceleration region are formed, thereby matching the core body speed V1 which is transversely arranged and has a pitch of P1 with the core body speed V4 which is longitudinally arranged and has a pitch of P2, namely, perfectly matching the speed V1 with V4 through variable speed movement, the problem of crumpling (front and back speed difference) when the product is switched from high-speed rotation to backward connection is solved.

After passing through the variable-speed variable-cross mechanism 2, the longitudinally-arranged and conveyed cores are changed into transversely-arranged and conveyed, meanwhile, the conveying speed of the cores is reduced so as to adapt to the condition that the distance between the cores is reduced, then, abdomen rubber bands are bonded on the inner-layer non-woven fabric (glue is sprayed on the inner-layer non-woven fabric by a third glue spray gun 31 in advance, then, the abdomen rubber bands on the abdomen rubber band rack 26 are bonded with the inner-layer non-woven fabric), and arc rubber bands are applied between the outer-layer non-woven fabric and the inner-layer non-woven fabric through an arc rubber band; the process of applying the arc-shaped rubber band is as follows:
