They are made of non-woven fabrics, toilet paper, fluff pulp, high-molecular water-absorbent resin, PE film, rubber bands and other materials. The core of the diaper is the key component for absorbing urine. There are currently double-core diapers on the market. The absorption capacity of double-core diapers is usually higher than that of single-core diapers, which can be as high as 1200ml. It is 30%-40% higher than that of single-core diapers. This means that they can meet the baby's wearing needs for a longer time and reduce the frequency of changes. The upper core in the double-core structure can quickly absorb urine to ensure the surface Dry and comfortable, while the lower core effectively locks moisture to ensure comfort for long-term use.

The first diaper core placement seats 2 and the second diaper core placement seats 3 are the same in number and have one-to-one corresponding positions. The tops of the first diaper core placement seats 2 and the second diaper core placement seats 3 are both provided with positioning grooves 201, and a mobile adsorption unit 4 is installed on the frame of the conveyor belt 1, wherein the positioning groove 201 of the first diaper core placement seat 2 is used One of the cores of the diaper is positioned and placed, and the positioning groove 201 of the second diaper core placement seat 3 is used to position and place the other core of the diaper. The first diaper core placement seat 2 and multiple second diaper core placement seats 3 are driven by the conveyor belt 1 to move and transport. When moving to the mobile adsorption unit 4, the diaper core in the second diaper core placement seat 3 is adsorbed and fixed by the mobile adsorption unit 4, and then moved to the top of the diaper core in the first diaper core placement seat 2 for stacking, so that when the double cores of the diaper are prepared, the stacking positioning is accurate to avoid offset, which helps to combine the two cores through subsequent lamination and pressing processing to improve product quality.

[0025] In this embodiment, if Figure 3As shown, the mobile adsorption unit 4 includes a fixed frame 41 and a fixed plate 43 fixedly connected to the frame of the conveyor belt 1. A displacement mechanism 42 for adjusting the position of the fixed plate 43 between the first diaper core placement seat 2 and the second diaper core placement seat 3 is installed on the fixed frame 41. The fixed plate 43 is an L-shaped structure. A lifting member 44 is fixedly connected to the fixed plate 43. The driving end of the lifting member 44 passes through the fixed plate 43 and is fixedly connected to a position adjustment mechanism 45. The bottom of the position adjustment mechanism 45 is connected to a support rod 46. The bottom of the support rod 46 is fixedly connected to a mounting plate 47. The bottom of the mounting plate 47 is fixedly connected to a plurality of vacuum suction cups 48. The vacuum suction cups 48 are connected to an external vacuum device. A mounting plate 47 is set between the first diaper core placement seat 2 and the second diaper core placement seat 3. There is a position guiding structure, which is used to make the mounting plate 47 and the vacuum suction cup 48 move back and forth between the first diaper core placement seat 2 and the second diaper core placement seat 3 through the operation of the displacement mechanism 42. The vacuum suction cup 48 is used to adsorb and fix the core, so that the core in the second diaper core placement seat 3 is adsorbed and moved to the top of the core in the first diaper core placement seat 2. In the process of stacking the two cores, the position guiding structure and the position adjusting mechanism 45 are used to adjust the position of the mounting plate 47 and the vacuum suction cup 48 to ensure that the two cores are accurately aligned when stacked. In this embodiment, the lifting member 44 is an electric telescopic rod. Of course, in other embodiments, the lifting member 44 can also be an electric push rod, a motor screw lifting module, etc., as long as the longitudinal lifting of the mounting plate 47 can be achieved.

[0026] In this embodiment, if Figure 2 and Figure 5As shown, the position guide structure includes a positioning guide plate 202 fixedly connected to the top of the first diaper core placement seat 2 and the second diaper core placement seat 3, and four positioning guide plates 202 are provided, which are respectively located around the outside of the positioning groove 201 on the first diaper core placement seat 2 and the second diaper core placement seat 3, and the upper half of the positioning guide plate 202 is designed to expand in the direction away from the positioning groove 201. The position guide structure also includes a guide member 49 fixedly connected to the top of the mounting plate 47, and four guide members 49 are provided, which are respectively located around the periphery of the mounting plate 47. The positions of the guide members 49 and the positioning guide plates 202 correspond one to one. The guide member 49 includes a guide member fixedly connected to the mounting plate 47. The fixing seat 491 at the top of the mounting plate 47 is rotatably connected to the fixing seat 491 with a roller 492. When the mounting plate 47 moves to the second diaper core placement seat 3 to adsorb the core or the mounting plate 47 moves to the first diaper core placement seat 2 to place the core, the mounting plate 47 moves to the top of the second diaper core placement seat 3 of the first diaper core placement seat 2 and is placed between the four positioning guide plates 202. The roller 492 contacts the inner wall of the positioning guide plate 202 to achieve adjustment of the position of the mounting plate 47 and the vacuum suction cup 48. The setting of the roller 492 reduces the friction between the mounting plate 47 and the positioning guide plate 202, which helps to smoothly adjust the position of the mounting plate 47.

[0027] In this embodiment, if Figure 4 As shown, the position adjustment mechanism 45 includes a fixed frame 451 fixedly connected to the driving end of the lifting member 44, a movable frame 452 arranged inside the fixed frame 451, and an adjustment seat 457 arranged inside the movable frame 452. Two first slide bars 453 are fixedly connected to the fixed frame 451 in a horizontal direction. The movable frame 452 is slidably sleeved on the two first slide bars 453. A first spring 454 is sleeved between the outer wall of the movable frame 452 and the inner wall of the fixed frame 451 and located on the outside of the first slide bars 453. Two second slide bars 455 are fixedly connected to the movable frame 452 in a longitudinal direction. The adjustment seat 457 is slidably sleeved on the two second slide bars 455. 55 is sleeved with a second spring 456 on the outer side, and the top of the support rod 46 is fixedly connected to the adjustment seat 457. When the mounting plate 47 moves to the adjustment position inside the four positioning guide plates 202, the adjustment seat 457 is synchronously displaced with the mounting plate 47 through the support rod 46, so that the adjustment seat 457 slides on the second slide bar 455 to adjust the longitudinal position, and the moving frame 452 moves on the first slide bar 453 to adjust the lateral position, so as to adjust the position of the mounting plate 47 and the vacuum suction cup 48. When the mounting plate 47 leaves the area of the positioning guide plate 202, the first spring 454 and the second spring 456 are provided to reset the moving frame 452 and the adjustment seat 457, thereby resetting the positions of the mounting plate 47 and the vacuum suction cup 48 to facilitate subsequent work.

[0028] In this embodiment, if Figure 3 As shown, the displacement mechanism 42 includes a screw rod 421 rotatably connected to the inside of the fixed frame 41 and a driving motor 422 installed on the outer wall of the fixed frame 41. The output end of the driving motor 422 is fixedly connected to one end of the screw rod 421. Two guide rods 423 are symmetrically fixedly connected below the screw rod 421 and located inside the fixed frame 41. A moving seat 424 is threadedly connected to the screw rod 421. The moving seat 424 is also slidably connected to the two guide rods 423. The fixed plate 43 is fixedly connected to one side of the moving seat 424. The driving motor 422 drives the screw rod 421 to rotate, driving the moving seat 424 to move axially along the screw rod 421. The setting of the guide rod 423 limits the longitudinal rotation of the moving seat 424 to ensure the stability of the movement of the moving seat 424, so that the mounting plate 47 and the vacuum suction cup 48 can move back and forth between the first diaper core placement seat 2 and the second diaper core placement seat 3.

[0029] like Figure 1 As shown, a positioning member 5 is installed on the frame of the conveyor belt 1 near the fixed frame 41. In this embodiment, the positioning member 5 is an infrared radiation sensor, and the positioning member 5 is electrically connected to the controller of the device. When the first diaper core placement seat 2 and the multiple second diaper core placement seats 3 move to the positioning member 5, the signal is transmitted to the controller to control the conveyor belt 1 to stop working and control the mobile adsorption unit 4 to work, thereby realizing automated production and preparation. Of course, in other embodiments, the positioning member 5 can also be other components with positioning functions.

[0030] The control method of the present invention is to control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. Moreover, the present invention is used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.

[0031] Working principle: When in use, one of the cores of the diaper is positioned and placed in the positioning groove 201 of the first diaper core placement seat 2, and the other core of the diaper is positioned and placed in the positioning groove 201 of the second diaper core placement seat 3. The first diaper core placement seat 2 and multiple second diaper core placement seats 3 are driven to move and transport by the conveyor belt 1. When moving to the mobile adsorption unit 4, the positioning member 5 senses that the first diaper core placement seat 2 and the second diaper core placement seat 3 are in place, and transmits a signal to the controller to control the conveyor belt 1 to stop working. At the same time, the driving motor 422 is controlled to drive the screw rod 421 to rotate, driving the moving seat 424 to move axially along the screw rod 421, and moving the mounting plate 47 to the top of the second diaper core placement seat 3. The lifting member 44 drives the mounting plate 47 to descend between the four positioning guide plates 202 on the second diaper core placement seat 3, and passes through the guide member 4 9 contacts the positioning guide plate 202, pushes the adjustment seat 457 to slide on the second slide bar 455 to adjust the longitudinal position, and moves the moving frame 452 on the first slide bar 453 to adjust the lateral position, adjusts the mounting plate 47 to the accurate position, and then uses the vacuum suction cup 48 to adsorb and fix the core on the second diaper core placement seat 3, and then the lifting member 44 is reset, and the driving motor 422 drives the screw rod 421 to rotate, driving the moving seat 424 to move, and moves the mounting plate 47 to the top of the first diaper core placement seat 2, and the lifting member 44 works again to drive the mounting plate 47 to move between the four positioning guide plates 202 on the first diaper core placement seat 2, adjusts the position of the mounting plate 47, and then the vacuum suction cup 48 contacts to stack the two cores, so that when the diaper double core is prepared, the stacking positioning is accurate to avoid offset, which helps to combine the two cores through subsequent lamination and pressing processing to improve product quality.

[0032] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
