[0002] Sanitary napkins are a kind of daily sanitary products. Sanitary napkin packaging equipment has greatly increased the production of sanitary napkins. During the packaging process, after the sanitary napkins are affixed with adhesive stickers, they need to be flipped over so that the adhesive sticker side faces down for transmission. The existing sanitary napkin flipping device directly transmits the sanitary napkins after flipping them over without a limiting device. The sanitary napkins may not maintain a uniform position and direction during the flipping process and the packaging process, which affects the consistency of the packaging and leads to poor product packaging.

[0024] The specific arrangement and function of the turning device 4 and the adjusting device 5 will be described in detail below.

[0025] In this embodiment: the flipping device 4 includes a first motor 401, the first motor 401 is fixedly connected to the surface of a group of support columns, the output end of the first motor 401 is fixedly connected to a rotating shaft 402, and the rotating shaft 402 is rotatably connected to the surface of a group of support platforms 3 close to the first motor 401.

[0026] The effects achieved by the above components are: starting the first motor 401 causes the rotating shaft 402 to rotate in a group of supporting platforms 3 close to the first motor 401 .

[0027] Specifically, one end of the rotating shaft 402 away from the first motor 401 is fixedly connected to a negative pressure box 403, and the negative pressure box 403 is rotatably connected to the surface of a group of support platforms 3 away from the first motor 401. The side of the negative pressure box 403 away from the first motor 401 is fixedly connected to a connecting pipe 404, and the other end of the connecting pipe 404 is fixedly connected to an exhaust box 405.

[0028] The effects achieved by the above components are as follows: the vacuum box 405, the connecting pipe 404 and the negative pressure box 403 are provided to facilitate negative pressure adsorption of the sanitary napkin.

[0029] Specifically, the inner surface of the vacuum box 405 is fixedly connected to the second motor 406, the output end of the second motor 406 is fixedly connected to the fan 407, the surface of the rotating shaft 402 is fixedly connected to the cylinder 408, the surface of the cylinder 408 is provided with placement grooves 409, and the number of the placement grooves 409 is four groups and they are symmetrically arranged.

[0030] The effect achieved by the above components is: four groups of placement grooves 409 are set to place sanitary napkins, and the thickness of the placement grooves 409 can just hold a group of sanitary napkins. When the cylinder 408 rotates, a group of sanitary napkins falls into the placement grooves 409. As the cylinder 408 rotates, other sanitary napkins are held against the surface of the cylinder 408 until the next group of placement grooves 409. The placement grooves 409 rotate half a circle and arrive directly above the conveying platform 2.

[0031] Specifically, a plurality of adsorption holes 410 are provided on the surface of the placement groove 409, and an exhaust pipe 411 is fixedly connected to the surface of the adsorption hole 410, one end of the exhaust pipe 411 is fixedly connected to the surface of the negative pressure box 403, and a placement box 412 is fixedly connected to the surface of the support platform 3, and the placement box 412 corresponds to the position of the placement groove 409.

[0032] The effects achieved by the above components are: starting the second motor 406 to drive the fan 407 to rotate, extracting the air in the negative pressure box 403 through the connecting pipe 404, and then making the adsorption hole 410 generate a certain negative pressure adsorption force through the exhaust pipe 411, and during the rotation of the cylinder 408, the already thin sanitary napkin is adsorbed in the placement groove 409 until the placement groove 409 rotates half a circle and comes to the top of the conveying platform 2, the second motor 406 is reversed so that the adsorption hole 410 no longer adsorbs the sanitary napkin, and under the influence of the sanitary napkin's own gravity, the sanitary napkin falls on the conveying platform 2, and at this time the sanitary napkin achieves stable flipping.

[0033] Specifically, an adjusting device 5 is provided on the surface of the support platform 3, and the adjusting device 5 includes a first bidirectional threaded rod 501, which is rotatably connected to the surface of the support platform 3, and a rotating valve 502 is fixedly connected to one end of the bidirectional threaded rod close to the first motor 401, and a first movable block 503 is threadedly connected to the surface of the first bidirectional threaded rod 501, and the number of the first movable blocks 503 is two groups, and a first clamping plate 504 is fixedly connected to the surface of the first movable block 503.

[0034] The effect achieved by the above components is: rotating the rotary valve 502 causes the first bidirectional threaded rod 501 to rotate, and then the two groups of first movable blocks 503 drive the first clamping plates 504 to move towards or away from each other, thereby limiting sanitary napkins of different sizes during the transmission process to prevent their position and direction from changing.

[0035] Specifically, a slide groove 511 is provided on the surface of the placement box 412 , and a telescopic rod 505 is fixedly connected to the surface of the support platform 3 , and one end of the telescopic rod 505 is fixedly connected to the surface of the first clamping plate 504 .

[0036] The effects achieved by the above components are: the telescopic rod 505 is arranged to cooperate with the movement of the first clamping plate 504, so as to restrict the first clamping plate 504 and the first movable block 503 from rotating on the first bidirectional threaded rod 501, and also to provide stability assistance for the first clamping plate 504 with a longer length.

[0037] Specifically, the surface of the support platform 3 is rotatably connected to the second bidirectional threaded rod 506, the surfaces of the second bidirectional threaded rod 506 and the first bidirectional threaded rod 501 are fixedly connected to the pulley 507, the surface of the pulley 507 is transmission-connected to the conveyor belt 508, the surface of the second bidirectional threaded rod 506 is threadedly connected to the second movable block 509, the number of the second movable blocks 509 is two groups, the surface of the second movable block 509 is fixedly connected to the second splint 510, the second splint 510 is slidably connected to the surface of the slide groove 511, and the side where the first splint 504 and the second splint 510 are close to each other is fixedly connected to a cushion 512.

[0038] The effect achieved by the above components is: the second bidirectional threaded rod 506 rotates to drive the second movable block 509 to move toward or away from each other, thereby causing the second clamping plate 510 to slide in the slide groove 511, thereby adjusting the size of the placement box 412 to avoid changes in the position and direction of the sanitary napkin when it moves in the placement box 412. The pulley 507 and the conveyor belt 508 are set to synchronize the rotation of the first bidirectional threaded rod 501 to the second bidirectional threaded rod 506, and the soft pad 512 is set to avoid the first clamping plate 504 and the second clamping plate 510 from being in hard contact with the sanitary napkin and causing damage to it.

[0039] Working principle: By setting the turning device 4, when the sanitary napkins need to be turned over so that the side with the adhesive sticker faces downward for transmission, first put multiple groups of sanitary napkins into the placement box 412, start the first motor 401 and the second motor 406, the first motor 401 makes the rotating shaft 402 drive the cylinder 408 to rotate, when a group of placement slots 409 rotates to the position corresponding to the placement box 412, a group of sanitary napkins just falls into the placement slots 409, and at the same time the second motor 406 drives the fan 407 to rotate, and the air in the negative pressure box 403 is filled with air through the connecting pipe 404. The air is extracted, and then the suction hole 410 generates a certain negative pressure adsorption force through the suction pipe 411. During the rotation of the cylinder 408, the already thin sanitary napkin is adsorbed in the placement groove 409 until the placement groove 409 rotates half a circle and comes to the top of the conveying platform 2. The second motor 406 is reversed so that the adsorption hole 410 no longer adsorbs the sanitary napkin, and under the influence of the sanitary napkin's own gravity, the sanitary napkin falls on the conveying platform 2. At this time, the sanitary napkin achieves stable flipping. By setting the flipping device 4, the sanitary napkin with the adhesive sticker on the back can be flipped while keeping its position. The consistency of the position and direction of the sanitary napkin is achieved, so that the packaging defects caused by the change of the position and direction of the sanitary napkin are avoided, and the stability of the equipment is effectively improved. In addition, by setting the adjusting device 5, when sanitary napkins of different sizes need to be transported and turned over, the rotating valve 502 is first rotated according to the size of the sanitary napkin to rotate the first bidirectional threaded rod 501, and at the same time, the second bidirectional threaded rod 506 is rotated synchronously through the pulley 507 and the conveyor belt 508, so that the first movable block 503 and the second movable block 509 are synchronously moved towards or away from each other, so as to adjust the distance between the second clamping plate 510 to avoid the change of the position and direction of the sanitary napkin when it moves in the placement box 412, and at the same time, the distance between the first clamping plate 504 is adjusted to avoid the change of the position and direction during the transmission process. By setting the adjusting device 5, the distance between the first clamping plate 504 and the second clamping plate 510 is synchronously adjusted to ensure that the position and direction of sanitary napkins of different sizes remain consistent during the turning and transmission process, so as to avoid the situation that the packaging defects caused by the change of the position and direction are avoided, and the convenience of the equipment is effectively improved.
