Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sanitary napkins, in particular to a device for adding freeze-dried powder into sanitary napkins. Background Art
[0002] There are a large number of normal parasites in the vagina of healthy women, including aerobic bacteria and anaerobic bacteria. The acidic environment created by lactobacilli is also conducive to reducing the negative charge on the cell surface and removing the sugar groups covering the surface of the receptor, exposing the receptor and facilitating bacterial adhesion. Therefore, vaginal lactobacilli play a vital role in maintaining normal vaginal flora.
[0003] Among them, the menstrual period is an important stage for women, but also a very vulnerable stage for women, because their bodies will become weak due to excessive menstrual blood loss. In a weak state, bacteria are most likely to attack their bodies, thereby inducing a series of gynecological diseases, such as vulvar congestion, edema, pain, and inflammation of the reproductive system. In order to protect the body from bacterial damage, an effective protective measure has evolved to "treat bacteria with bacteria" to resist the threat of pathogens. Specifically, vaginal probiotics are added to sanitary napkins to prevent gynecological diseases in daily life.
[0004] The specific measures for adding vaginal probiotics to sanitary napkins are mainly to mix the mixed bacteria with skim milk and store it in a -80℃ refrigerator for 24 hours, make freeze-dried powder in a freeze dryer, and then evenly distribute the probiotic freeze-dried powder in the inner absorbent layer of the sanitary napkin. However, it is inconvenient to add probiotic freeze-dried powder into sanitary napkins. Utility Model Content
[0005] In order to solve at least one of the technical problems mentioned in the background technology, the purpose of the present utility model is to provide a device for adding freeze-dried powder into a sanitary napkin, so as to facilitate adding freeze-dried probiotic powder into the sanitary napkin.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a device for adding freeze-dried powder to a sanitary napkin, comprising a base, a conveying mechanism is installed on the base, a powder spraying mechanism is arranged on the base and above the conveying mechanism, a lifting mechanism is installed on the base for driving the powder spraying mechanism to move in a vertical direction, the powder spraying mechanism comprises a plurality of hollow pins, an elastic cover for inflation is fixedly installed on the upper side of the hollow pins, a cover plate is fixedly installed on the upper side of the elastic cover, the cover plate is fixedly connected to the lifting mechanism, a positioning block is fixedly installed on the hollow pins, a limiting frame is fixedly installed on the base, a socket for inserting the hollow pins is provided on the limiting frame, a one-way air outlet valve is installed on the hollow pin, a one-way air inlet valve is installed on the elastic cover, and when the hollow pin is partially inserted into the sanitary napkin core, the positioning block abuts against the limiting frame.
[0007] Furthermore, the lifting mechanism includes an electric guide rail fixedly mounted on the base, an electric slider is slidably arranged on the electric guide rail, and the electric slider is fixedly connected to the cover plate.
[0008] Furthermore, a guide rod is fixedly mounted on the lower side of the positioning block, and a through hole for the guide rod to pass through is provided on the limiting frame.
[0009] Furthermore, a plurality of spring pieces are installed in the elastic cover.
[0010] Furthermore, the conveying mechanism includes two rollers rotatably mounted on a base, a conveyor belt is commonly mounted on the two rollers, and a motor for driving the rollers to rotate is mounted on the base.
[0011] Compared with the prior art, the beneficial effect of the utility model is as follows: as the sanitary napkin core to be processed moves to the lower side of the hollow pin, the lifting mechanism drives the cover plate to start moving downward, and then drives the elastic cover and the hollow pin on the cover plate to move downward. When the lower end of the hollow pin is inserted into the sanitary napkin core, the positioning block on the hollow pin just abuts against the limit frame, so that the hollow pin no longer moves. As the lifting mechanism drives the elastic cover to continue to move, the hollow pin no longer moves, and a plurality of spring plates are installed in the elastic cover. After the elastic cover is compressed, the spring plates are deformed, and elastic potential energy is accumulated inside. The elastic cover is opened for compression, and the internal volume is reduced. The internal air is compressed into the hollow pin, and then sprayed out from the lower end of the hollow pin through the one-way air outlet valve in the hollow pin. At the same time, the freeze-dried powder in the hollow pin enters the sanitary napkin core along with the airflow, thereby completing the addition of freeze-dried powder to the sanitary napkin core.

DETAILED DESCRIPTION
[0016] The technical solutions in the embodiments of the utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0017] See also Figure 1-3 The present embodiment provides a device for adding freeze-dried powder to a sanitary napkin, comprising a base 1, a conveying mechanism 2 is installed on the base 1, a powder spraying mechanism 3 is arranged on the base 1 and above the conveying mechanism 2, a lifting mechanism 4 is installed on the base 1 for driving the powder spraying mechanism 3 to move in a vertical direction, the powder spraying mechanism 3 comprises a hollow pin 31, an elastic cover 32 for inflation is fixedly installed on the upper side of the hollow pin 31, a cover plate 33 is fixedly installed on the upper side of the elastic cover 32, the cover plate 33 is fixedly connected to the lifting mechanism 4, a positioning block 34 is fixedly installed on the hollow pin 31, a limiting frame 35 is fixedly installed on the base 1, a socket 36 for inserting the hollow pin 31 is opened on the limiting frame 35, a one-way air outlet valve 37 is installed on the hollow pin 31, a one-way air inlet valve 38 is installed on the elastic cover 32, when the hollow pin 31 is partially inserted into the sanitary napkin core, the positioning block 34 abuts against the limiting frame 35.
[0018] The sanitary napkin core to be processed is placed on the conveying mechanism 2, and the sanitary napkin core is conveyed to the bottom of the powder spraying mechanism 3, that is, the bottom of the hollow needle 31. In the initial state, the elastic cover 32 is in the stretched state, the hollow needle 31 is filled with freeze-dried powder, and the volume of the elastic cover 32 is at the maximum value.
[0019] As the sanitary napkin core to be processed moves to the lower side of the hollow pin 31, the lifting mechanism 4 drives the cover plate 33 to start moving downward, thereby driving the elastic cover 32 on the cover plate 33 and the hollow pin 31 to move downward. When the lower end of the hollow pin 31 is inserted into the sanitary napkin core, the positioning block 34 on the hollow pin 31 just abuts against the limit frame 35, so that the hollow pin 31 no longer moves. As the lifting mechanism 4 drives the elastic cover 32 to continue moving, the hollow pin 31 no longer moves, so the elastic cover 32 opens. The elastic cover 32 begins to compress. Since a plurality of spring pieces are installed in the elastic cover 32, the spring pieces are deformed after the elastic cover 32 is compressed, and elastic potential energy is accumulated inside. After the elastic cover 32 is compressed, the internal volume is reduced, and the air in the elastic cover 32 is compressed into the hollow needle 31, and then is ejected from the lower end of the hollow needle 31 through the one-way air outlet valve 37 in the hollow needle 31. At the same time, the freeze-dried powder in the hollow needle 31 enters the sanitary napkin core along with the air flow, thereby completing the addition of the freeze-dried powder to the sanitary napkin core.
[0020] When the lifting mechanism 4 drives the cover plate 33 to move upward, the elastic cover 32 is gradually moved upward by the cover plate 33. Because the elastic cover 32 is in a compressed state at this time, it is necessary to wait for the elastic cover 32 to recover to its original state before the hollow insertion needle 31 can be driven to move upward. During the recovery process of the elastic cover 32, it is necessary to inhale air from the outside. At this time, the one-way air outlet valve 37 is in a closed state. Only through the one-way air inlet valve 38 can the elastic cover 32 be replenished with gas, thereby preventing the elastic cover 32 from inhaling air and adsorbing the freeze-dried powder in the sanitary napkin core again through the hollow insertion needle 31. After the elastic cover 32 recovers, it drives the hollow insertion needle 31 to detach from the sanitary napkin, replenishes the freeze-dried powder in the hollow insertion needle 31, and waits for the next sanitary napkin to be added.
[0021] The lifting mechanism 4 includes an electric guide rail 41 fixedly mounted on the base 1, on which an electric slider 42 is slidably arranged, and the electric slider 42 is fixedly connected to the cover plate 33. The movement of the cover plate 33 is controlled by controlling the position of the electric slider 42 on the electric guide rail 41.
[0022] In order to improve the movement stability of the hollow plug 31, a guide rod 5 is fixedly installed on the lower side of the positioning block 34, and a through hole 6 for the guide rod 5 to pass through is provided on the limit frame 35. During the movement of the hollow plug 31, the positioning block 34 is driven to move, the positioning block 34 drives the wire rod to move, and the guide rod 5 moves in the vertical direction along the through hole 6, thereby guiding and correcting the hollow plug 31, reducing the interaction force between the hollow plug 31 and the inner wall of the plug hole 36, and protecting the hollow plug 31.
[0023] The conveying mechanism 2 includes two rollers 21 rotatably mounted on the base 1, and a conveyor belt 22 is commonly mounted on the two rollers 21. A motor 23 for driving the rollers 21 to rotate is mounted on the base 1. The sanitary napkin is placed on the conveyor belt 22, and the motor 23 drives the belt, which drives the rollers 21 to rotate (not shown in the figure), and the rollers 21 drive the conveyor belt to move.
[0024] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
