Description

Technical Field

[0001] The invention belongs to the technical field of sanitary napkin disinfection and sterilization, and specifically relates to a disinfection and sterilization device for sanitary napkin production and a sterilization method thereof. Background Art

[0002] Sanitary napkins are a type of sanitary product used by women during menstruation. The main materials are cotton, pulp, or polymers formed by composites of the above materials, and polymer composite paper and other materials. Sanitary napkins are disinfected during production, mainly to ensure that the sanitary napkins will not cause harm to the user's health during use and reduce the risk of infection.

[0003] A Chinese patent with application number 202210946651.4 discloses a disinfection and sterilization device for sanitary napkin production, which relates to the technical field of sanitary napkin production. The disinfection and sterilization device for sanitary napkin production includes a base plate and a U-shaped frame fixed to the base plate, and a conveying component for conveying sanitary napkins is provided on the base plate. A proximity switch for identification during the conveying process of sanitary napkins is installed on the U-shaped frame, and a first sterilization component for sterilization and disinfection during the conveying process of sanitary napkins is provided on the U-shaped frame. This sanitary napkin production disinfection and sterilization device drives the mounting plate to move toward the conveyor belt through the lifting component before sterilization. During the process of the mounting plate being forced to move toward the conveyor belt, the front and back and left and right sides of the positioned sanitary napkin are pushed in the center to cause it to bulge through transmission. The bulging of the sanitary napkin makes it easier for the disinfection steam and ultraviolet irradiation lamp to disinfect and sterilize the sanitary napkin more comprehensively, further improving the disinfection and sterilization effect of the sanitary napkin. However, when disinfecting and sterilizing the sanitary napkin, the invention needs to stop the conveyance of the sanitary napkin, and then position, clamp and bulge the sanitary napkin, which affects the efficiency of disinfection and sterilization.

[0004] The production process of sanitary napkins mainly includes processes such as absorbent cotton, fiber collection machine, compaction, embossing, diversion, peripheral sealing, forming, flipping, horizontal change, longitudinal folding, quick-sticking and disinfection. However, when the folded sanitary napkins are disinfected and sterilized, only the surface of the sanitary napkins can be simply disinfected and sterilized by ultraviolet rays, and the disinfection and sterilization effect is poor. Considering that the sanitary napkins are transported by conveyor belts during the production process, if the transportation of the sanitary napkins must be stopped every time the sanitary napkins are disinfected and sterilized, the long-term work will affect the overall efficiency of disinfection and sterilization.

[0005] Therefore, in order to solve the above problems, it is necessary to provide a disinfection and sterilization device for sanitary napkin production and a sterilization method thereof. Summary of the invention

DETAILED DESCRIPTION

[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] Embodiment 1

[0051] The production process of sanitary napkins mainly includes processes such as absorbent cotton, fiber collection machine, compaction, embossing, diversion, peripheral sealing, forming, flipping, horizontal change, longitudinal folding, quick-sticking and disinfection. However, when the folded sanitary napkins are disinfected and sterilized, ultraviolet rays can only be used to simply disinfect and sterilize the surface of the sanitary napkins, and the disinfection and sterilization effect is poor. Considering that the sanitary napkins are transported by conveyor belts during the production process, if the transportation of the sanitary napkins must be stopped every time the sanitary napkins are disinfected and sterilized, the long-term work will affect the efficiency of disinfection and sterilization.

[0052] See also Figure 1 - Fig.10 The present invention provides the following technical solution: A disinfection and sterilization device for sanitary napkin production, comprising a mounting base 1, a support frame 2, a transmission component 3 and a sterilization component 4, and also comprising:

[0053] The guide assembly 5 includes two symmetrically arranged guide members 51 fixedly connected to the inner side of the support frame 2 , and the two guide members 51 are used to guide and squeeze the sanitary napkins transported by the transmission assembly 3 .

[0054] The limiting component 6 includes a friction member 61 arranged on the top of the guide component 5 , and a plurality of light leakage holes 62 are opened on the top of the friction member 61 . The friction member 61 is used to rub the top of the sanitary napkin transported by the transmission component 3 .

[0055] The compacting component 7 is arranged at the top of the guide component 5 near the discharge port of the transmission component 3, and is used to compact and reset the sanitary napkin passing through the limiting component 6.

[0056] Two symmetrically arranged sliding members 63 are fixedly connected to the bottom of the friction member 61, and sliding grooves 64 corresponding to the two sliding members 63 are provided on the tops of the two guide members 51. The two sliding members 63 are movably connected to the corresponding sliding grooves 64 respectively, and each of the guide members 51 is provided with a limiting groove 65 connected to the corresponding sliding groove 64. An adjusting groove 66 is provided on the bottom of one side of each sliding member 63 close to the limiting groove 65, and an adjusting member 67 slidably connected to the corresponding limiting groove 65 is slidably connected inside each adjusting groove 66. A first elastic member 68 is connected between the side of each adjusting member 67 away from the limiting groove 65 and the inner wall of the corresponding adjusting groove 66.

[0057] The sliding member 63 can move horizontally or vertically inside the slide groove 64. There is a moving distance between the sliding member 63 and the adjusting groove 66, so as to facilitate the horizontal movement of the sliding member 63 inside the slide groove 64. When the sliding member 63 moves horizontally inside the slide groove 64, the adjusting member 67 can always be inside the limiting groove 65 under the action of the first elastic member 68. When the sliding member 63 moves vertically inside the slide groove 64, the adjusting member 67 can move synchronously inside the limiting groove 65.

[0058] A mounting groove 69 connected to the slide groove 64 is provided at the top of each guide member 51. A contact piece 611 is rotatably connected to the inner side of the top of the two guide members 51 via a rotating shaft 610. A first extrusion member 612 fixedly connected to the rotating shaft 610 is provided inside each mounting groove 69. A lever 613 fixedly connected to the corresponding sliding member 63 is rotatably connected inside each mounting groove 69. When the contact piece 611 rotates, the rotating shaft 610 can drive the two first extrusion members 612 to squeeze the corresponding lever 613 at the same time, so that the two sliding members 63 can move in the direction away from the guide member 51 inside the corresponding slide groove 64, so that the friction member 61 can be separated from the friction on the top of the sanitary napkin.

[0059] In actual use, the distance between the two guide members 51 can be set according to needs to ensure that the folded sanitary napkin can be slightly squeezed and bulged by the two guide members 51 when transported between the two guide members 51, and the bulging height should be sufficient to ensure contact between the friction member 61 and the sanitary napkin.

[0060] like Figure 5 As shown, the contact piece 611 is inclined, and the height of the side of the contact piece 611 close to the discharge port of the transmission component 3 is lower than the height of the side close to the feed port of the transmission component 3. The purpose is to limit the height of the sanitary napkin bulging by setting the height and the inclination angle of the contact piece 611, such as Figure 6 As shown, in a normal state, the two sliding members 63 can tilt one end of the lever 613 close to the first extruding member 612 under the action of their own gravity, push the first extruding member 612 to rotate, and keep the contact piece 611 in an inclined state.

[0061] A first fixed groove 614 corresponding to the position of the contact piece 611 is provided on the inner side of the two guide members 51, and a second fixed groove 615 corresponding to the position of the first fixed groove 614 is provided on the bottom of each guide member 51. A transfer bin 616 is fixedly connected to the interior of each first fixed groove 614, and a guide tube 617 connected to the corresponding transfer bin 616 is fixedly connected to the interior of each second fixed groove 615. A partition groove 618 connected to the corresponding guide tube 617 is provided to the interior of each slide groove 64. A sealing member 619 sealingly and slidably connected to the corresponding partition groove 618 is fixedly connected to the bottom of each sliding member 63. A plurality of nozzles 620 are provided on the corresponding side of the two transfer bins 616, and the outer wall of the transfer bin 616 remains flush with the inner side of the guide member 51.

[0062] Under normal conditions, that is, when the equipment is not working, the two sliding members 63 can fit with the bottom inner wall of the slide groove 64 under the action of their own gravity, so that the blocking member 619 can be completely inserted into the interior of the dividing groove 618, and the guide tube 617 can be blocked. The nozzle 620 on the transfer chamber 616 cannot spray air. When the contact piece 611 rotates, the rotating shaft 610 can drive the two first extrusion members 612 to squeeze the corresponding levers 613 at the same time, and the lever 613 drives the two sliding members 63 to move in the corresponding slide groove 64 in the direction away from the guide member 51, that is, move upward. At this time, the sliding member 63 does not contact the bottom inner wall of the slide groove 64, the blocking member 619 no longer blocks the guide tube 617, and the nozzle 620 on the transfer chamber 616 will spray air.

[0063] The transmission component 3 includes a synchronous belt 31, a driving roller 32, a driven roller 33 and a driving motor 34 for driving the driving roller 32 to rotate. The synchronous belt 31 is provided with a plurality of through holes 35. A gas tank 8 is provided inside the mounting base 1. The gas tank 8 is filled with disinfectant gas. A gas supply device 9 connected to the gas tank 8 is provided on the top of the gas tank 8. The gas supply device 9 is connected to two guide pipes 617. The gas supply device 9 can be connected to the two guide pipes 617 through a hose.

[0064] The disinfection gas filled in the gas tank 8 is selected according to actual needs. Commonly used disinfection gases include ethylene oxide, ozone, propylene glycol, etc. The gas supply equipment 9 is an air pump, which is used to transmit the gas inside the gas tank 8 to the inside of the two guide pipes 617. The transmission component 3 and the air pump are both existing technologies and will not be repeated here.

[0065] The sterilization component 4 includes an isolation chamber 41, and a plurality of ultraviolet lamps 42 are provided inside the isolation chamber 41 and on the inner side of the synchronous belt 31. Two guide members 51 are located below the isolation chamber 41. The inner sides of one end of the two guide members 51 close to the feed port of the transmission component 3 are wedge-shaped, so as to facilitate the entry of the sanitary napkin between the two guide members 51.

[0066] The light from the ultraviolet lamp 42 on the inner side of the synchronous belt 31 can pass through the through hole 35 to disinfect and sterilize the sanitary napkins on the synchronous belt 31. The light from the ultraviolet lamp 42 inside the isolation chamber 41 can pass through the light leakage hole 62 to disinfect and sterilize the sanitary napkins under the friction part 61. The sterilization component 4 and the ultraviolet lamp 42 are both existing technologies and will not be described in detail here.

[0067] It should be noted that, in actual use, the folded sanitary napkin is transported between the two guide members 51 through the transmission component 3. The two guide members 51 will slightly squeeze the sanitary napkin to make it bulge. The bulged sanitary napkin can contact the friction member 61. At this time, the friction member 61 will provide a friction force in the opposite direction of the transport to the sanitary napkin in transportation. Through the cooperation of the friction member 61 and the transmission component 3, the sanitary napkin in transportation by the transmission component 3 can be rubbed, which can increase the degree and effect of the bulging of the sanitary napkin. Although the folded sanitary napkin can be fixed by the adhesive backing, long-term rubbing will still cause the folded sanitary napkin to spread out. Therefore, the contact piece 611 is provided. When the bulged sanitary napkin passes under the bottom of the contact piece 611, the contact piece 611 can be squeezed by the sanitary napkin to rotate while limiting the height of the sanitary napkin. At this time, the contact piece 611 rotates, and the rotating shaft 610 can bring The two first extrusion members 612 are moved to squeeze the corresponding levers 613 at the same time, so that the two sliding members 63 can move in the direction away from the guide member 51 inside the corresponding slide groove 64, and the friction member 61 can be separated from the friction on the top of the sanitary napkin, so as to avoid the folded sanitary napkin from spreading out due to long-term friction. At the same time, when the two sliding members 63 move in the direction away from the guide member 51 inside the corresponding slide groove 64, the upward movement of the sliding member 63 will drive the blocking member 619 to break away from the blockage of the guide tube 617, so that the disinfecting gas entering the transfer chamber 616 can be ejected from the nozzle 620. Since the first fixed groove 614 corresponds to the position of the contact piece 611, and the sanitary napkin passes under the contact piece 611 in a bulging state, the disinfecting gas ejected from the nozzle 620 can enter the interior of the sanitary napkin, which can further disinfect and sterilize the sanitary napkin, thereby improving the effect and efficiency of disinfection and sterilization.

[0068] Embodiment 2

[0069] On the basis of the above embodiment, the friction piece is used to assist the sanitary napkin to swell, which requires the sanitary napkin to move a certain distance, and the efficiency is slow. Moreover, the sanitary napkin is still in a swollen state after disinfection and sterilization, which affects the subsequent packaging of the sanitary napkin.

[0070] See also Fig.11 - Fig.15The compaction assembly 7 includes a placement groove 71 opened at the top of the two guide members 51, and the two placement grooves 71 are fixedly connected with support members 72, and each support member 72 is rotatably connected with a connecting ring 73, and each connecting ring 73 is provided with two evenly distributed connecting grooves 74, and each connecting ring 73 is provided with an adapter 75, and each adapter 75 is provided with a guide groove 76 with the same number and corresponding position as the connecting grooves 74, and each guide groove 76 is slidably connected with a limit member 77 slidably connected to the corresponding connecting groove 74, and each limit member 77 is connected to a second elastic member 78 between the side away from the connecting groove 74 and the inner wall of the corresponding guide groove 76.

[0071] When the pressing roller 79 rotates, the limiting member 77 is always located inside the corresponding connecting groove 74 under the action of the second elastic member 78 .

[0072] A pressure roller 79 is fixedly connected to the corresponding side of the two adapters 75, and an extrusion rod 710 is fixedly connected to the side away from each other of the two connecting rings 73. A receiving groove 711 connected to the corresponding sliding groove 64 is provided on the top of each guide member 51, and a moving member 712 slidably connected to the corresponding sliding member 63 is slidably connected inside each receiving groove 711. A receiving cavity 713 connected to the corresponding receiving groove 711 and the placement groove 71 is provided inside each guide member 51, and an isolation plate 714 is slidably connected inside each receiving cavity 713. The height of the pressure roller 79 should be set according to actual needs.

[0073] like Fig.11 As shown, there is a gap between the adapter 75 and the inner wall of the connecting ring 73. When the bulged sanitary napkin passes through the bottom of the pressure roller 79, the pressure roller 79 can compact the bulged sanitary napkin. At this time, the pressure roller 79 can automatically adjust the pressure applied to the sanitary napkin. When the sanitary napkin is subjected to a greater force, the pressure roller 79 can drive the adapter 75 to move upward inside the connecting ring 73. When the sanitary napkin is subjected to a smaller force, the pressure roller 79 can drive the adapter 75 to move downward inside the connecting ring 73 to avoid hard contact between the sanitary napkin and the pressure roller 79, ensure that the sanitary napkin is subjected to uniform force, and prevent the sanitary napkin from being damaged. During the movement of the adapter 75 inside the connecting ring 73, the limit member 77 is always inside the guide groove 76 and the connecting groove 74. When the pressure roller 79 compacts the sanitary napkin, the friction between the pressure roller 79 and the sanitary napkin can cause the sanitary napkin in transportation to drive the pressure roller 79 to rotate.

[0074] like Figure 7As shown, each isolation plate 714 is fixedly connected to a first connecting rod 715 fixedly connected to the corresponding moving member 712 on one side close to the accommodating groove 711, and each isolation plate 714 is fixedly connected to a second connecting rod 716 that penetrates the accommodating cavity 713 on the other side, and each second connecting rod 716 is fixedly connected to a push plate 717 at one end that penetrates the accommodating cavity 713, and the outer walls of the two extrusion rods 710 are fixedly connected to second extrusion members 718, and the positions of the two second extrusion members 718 correspond to the positions of the two push plates 717 respectively, and a third elastic member 719 is connected between the side of each isolation plate 714 close to the accommodating groove 711 and the inner wall of the corresponding accommodating cavity 713, and the third elastic member 719 is sleeved on the outer wall of the corresponding first connecting rod 715, and rotating the two extrusion rods 710 can make the two second extrusion members 718 squeeze the corresponding push plate 717 at the same time, and can make the two moving members 712 push the two sliding members 63 to move synchronously in the direction away from the accommodating groove 711.

[0075] It should be noted that, in actual use, the sanitary napkin after disinfection and sterilization is still in a bulging state. When the bulging sanitary napkin passes through the bottom of the pressure roller 79, the pressure roller 79 can compact the bulging sanitary napkin. The pressure roller 79 can adjust the pressure applied to the sanitary napkin by moving the adapter 75 inside the connecting ring 73, so as to avoid hard contact between the sanitary napkin and the pressure roller 79, ensure that the sanitary napkin is evenly stressed, and prevent damage to the sanitary napkin. When the pressure roller 79 compacts the sanitary napkin, the friction between the pressure roller 79 and the sanitary napkin can drive the pressure roller 79 to rotate. The rotation of the pressure roller 79 can drive the two squeezing rods 710 to rotate synchronously, so that the two second squeezing members 7 18 squeezes the corresponding push plate 717 at the same time, which can make the isolation plate 714 squeeze the third elastic member 719, and can make the two movable members 712 push the two sliding members 63 to move synchronously in the direction away from the accommodating groove 711 inside the slide groove 64. When the second squeezing member 718 is not in contact with the push plate 717, the third elastic member 719 is reset, and the two movable members 712 will drive the two sliding members 63 to move synchronously in the direction close to the accommodating groove 711 inside the slide groove 64. Therefore, during the rotation process, the two sliding members 63 can drive the friction member 61 to move back and forth, and can perform reciprocating friction and kneading on the sanitary napkin that subsequently enters the bottom of the friction member 61, thereby accelerating the efficiency of the sanitary napkin swelling.
