Detailed Description

The application is described in further detail below with reference to fig. 1-4.

Embodiment one: an embodiment of the application provides a paper diaper performance detection device for detecting elasticity, air permeability and water absorbability of a paper diaper, the paper diaper performance detection device comprising:

a frame 100;

the extension and contraction detecting mechanism 200 is arranged on the frame 100, at least comprises an elastic air bag 210, and the paper diaper is sleeved on the elastic air bag 210 when the paper diaper detects the extension and contraction;

the ventilation detection mechanism 300 is arranged on the frame 100, and at least comprises a steam cover 310 and a detection cover 320, wherein the detection cover 320 is arranged right above the steam cover 310 in a lifting manner, steam is arranged in the steam cover 310, the detection cover 320 is used for detecting the steam, and the paper diaper is arranged between the steam cover 310 and the detection cover 320 when the paper diaper is subjected to ventilation detection and is sealed with the steam cover 310 and the detection cover 320;

the water absorption detection mechanism 400 is disposed on the frame 100, and at least comprises a shower screen 410, and the diaper is disposed under the shower screen 410 when detecting water absorption.

As shown in fig. 1 and 2, in the present embodiment, the stretch detecting mechanism 200, the air-permeability detecting mechanism 300, and the water-absorbency detecting mechanism 400 are exemplarily described for detecting the stretch property, the water permeability, and the water absorbency of the diaper, respectively. All three are arranged on the machine frame 100, and the middle part of the machine frame 100 can be provided with a detection platform for arranging the mechanisms so as to facilitate the detection personnel to perform related operation on the paper diaper.

As shown in fig. 2, in which the diaper is fitted over the elastic airbag 210 at the time of the stretchability detection, the process in which the diaper is changed with the volume change of the elastic airbag 210 can be observed by performing the operations of expanding and contracting the elastic airbag 210. When the elastic air bag 210 is inflated to a specified volume, it is observed whether or not the diaper is pulled apart in this state. If the diaper breaks due to stress during the expansion of the elastic air bag 210, it indicates that the diaper has poor stretchability and does not meet the use requirement. It should be noted that, the designated volume may be reasonably set according to the actual requirement of detection, for example, when different models and sizes of diapers have different required stretchability, the elastic air bag 210 may appropriately adjust the inflated designated volume; meanwhile, the adjustment mode can also be used for evaluating the excellent degree of the extensibility and contractibility of the paper diaper, namely, the larger the volume of the elastic air bag 210 is, the better the extensibility and contractibility of the paper diaper is.

And then, as the elastic air bag 210 is gradually contracted, it is observed whether the diaper is closely attached to the elastic air bag 210 in this state of rotation. If the diaper cannot be tightly attached to the elastic airbag 210 in the process of shrinking the elastic airbag 210, the diaper is also poor in stretchability and does not meet the use requirement. It should be noted that the foregoing process should be performed before the elastic air bag 210 is contracted so as not to deform the diaper. In this embodiment, the criterion for ensuring that the stretchability of the diaper is detected to be acceptable depends on the two conditions, so as to ensure that the diaper can be stretched to a larger state, so as to be convenient for wearing; meanwhile, the utility model can be attached to the human body after being worn.

As shown in fig. 2, when the air permeability is detected, the diaper is sandwiched between the steam cover 310 and the detection cover 320, and is sealed with both the steam cover 310 and the detection cover 320. When the air permeability of the diaper meets the requirement, the steam in the steam cover 310 floats up to be close to the diaper, and can smoothly pass through the diaper to enter the detection cover 320. By detecting whether steam exists in the detection cover 320 and the duration from the start of the test to the existence of steam in the detection cover 320, whether the air permeability of the diaper is qualified can be judged, and meanwhile, the excellent degree of the air permeability of the diaper can be judged, namely, the shorter the duration of detecting the existence of steam is, the better the air permeability is. In the embodiment, the paper diaper is ensured to be qualified in detection, and a large amount of bacteria can be prevented from breeding in the use process of the paper diaper due to poor air permeability.

As shown in fig. 2, when the water absorption test is performed, the diaper is horizontally placed under the shower screen 410, and the shower screen 410 sprays water to the diaper. And whether the water absorbability of the paper diaper is qualified can be judged by observing the absorption effect of the paper diaper on sprayed water and the time period of completely absorbing the water. If the paper diaper cannot suck water or the water is sucked for too long, the practical requirement is not met. It should be noted that, the spraying screen 410 may spray a specified amount of water to the diaper to ensure the detection standard; while the specified amount of water can be reasonably selected according to the actual detection needs. When a reasonable choice is made, the excellent degree of the water absorption of the diaper can be evaluated, that is, the more the water absorption amount is, the shorter the time taken for completely drying the water, and the better the water absorption.

It can be appreciated that the present application can detect the elasticity, air permeability and water absorption of the diaper effectively by providing the elastic air bags 210 for the diaper to be sleeved, the steam covers 310 and the detection covers 320 disposed at both sides of the diaper, and the shower screen 410 spraying water to the diaper, respectively, so as to achieve the purpose of accurately evaluating the aforementioned performances.

Specifically, the paper diaper performance detection device further includes a water pipe 500, the water pipe 500 is disposed in the rack 100, the water pipe 500 is communicated with the elastic air bag 210, and a first valve 600 is disposed at a communication position, and the first valve 600 is a three-way valve and is at least used for controlling the elastic air bag 210 to be communicated to an upstream or a downstream of the water pipe 500.

As shown in fig. 2, in the present embodiment, it is exemplarily illustrated that when the water pipe 500 communicates with the elastic bladder 210, it can fill water into the elastic bladder 210 to expand the elastic bladder 210; and may receive water discharged from the elastic bladder 210 to allow the elastic bladder 210 to contract. The water pipe 500 may be horizontally disposed with both ends respectively provided as a water inlet and a water outlet for water inlet and water discharge of the water pipe 500, respectively. The elastic bladder 210 may be disposed between the water inlet and the water outlet at a communication point with the water pipe 500. The elastic bladder 210 may communicate with the water pipe 500 through the first branch pipe 211, and the first branch pipe 211 may be vertically disposed to be perpendicular to the water pipe 500. The elastic balloon 210 may be sleeved on an end of the first branch pipe 211 remote from the water pipe 500 by a locking member such as a tie. The first valve 600 may be provided at a junction of the first branch pipe 211 and the water pipe 500, which is provided as a three-way valve, and may control at least upstream or downstream communication of the first branch pipe 211 and the water pipe 500. When the first valve 600 controls the first branch pipe 211 to communicate upstream of the water pipe 500, the water pipe 500 fills water into the elastic bladder 210 through the first branch pipe 211; when the first valve 600 controls the first branch pipe 211 to communicate downstream of the water pipe 500, water in the elastic bladder 210 is discharged into the water pipe 500 through the first branch pipe 211.

It can be appreciated that, in this embodiment, the water pipe 500 is provided to fill water into the elastic air bag 210, and meanwhile, the first valve 600 is provided to control the water filling and discharging time of the elastic air bag 210, so as to control the expansion and contraction process of the elastic air bag 210, which is particularly significant for controlling the expansion and contraction speed of the elastic air bag 210, that is, when the elastic air bag 210 is forced to deform by water, the deformation process of the elastic air bag 210 is easier to control, and the deformation speed is slower and longer than the airflow, so as to effectively obtain the situation when the diaper stretches and contracts, so as to accurately evaluate.

More specifically, the steam hood 310 is provided therein with the spray head 330, and the heater 340 is provided directly above the spray head 330, the heater 340 includes a heat conducting outer sleeve and a heat conducting wire, the heat conducting outer sleeve is arranged on the steam hood 310 in a penetrating manner, the heat conducting wire is arranged in the heat conducting outer sleeve in a penetrating manner, the spray direction of the spray head 330 faces the heat conducting wire, and the spray height is smaller than the maximum height of the steam hood 310, the spray head 330 is communicated with the water pipeline 500, and the communication place is provided with a second valve 700, and the second valve 700 is a three-way valve and is at least used for controlling the spray head 330 to be communicated to the upstream of the water pipeline 500, and the upstream of the control water pipeline 500 is communicated to the downstream of the water pipeline 500.

As shown in fig. 2, in the present embodiment, it is exemplarily illustrated that the spray head 330 may be vertically disposed within the steam hood 310 and one end is connected to the water pipe 500 through the steam hood 310 to communicate with the water pipe 500. The spray head 330 may be provided with a plurality of micro-porous structures for spraying water and atomizing the water, i.e. forming a spray mist. The heater 340 is used for instantaneously heating the mist to form steam. The heater 340 may be provided in a spiral shape and disposed directly above the spray head 330, and the spray direction of the spray head 330 is toward the heater 340. The heat conductive outer sleeve of the heater 340 may be provided as a circular tube and may be made of a metal material or a ceramic material. The thermal resistance wire can be made of metal materials, generates heat when the thermal resistance wire is electrified, and transmits the heat to the heat conducting outer sleeve. The water mist is formed and instantaneously heated to steam when sprayed on the heat conducting outer sleeve, and the steam is hot gas, which has a tendency to float upwards.

At this time, the detecting cover 320 may be lowered in a vertical direction to approach the steam cover 310, and the diaper is clamped between the detecting cover 320 and the steam cover 310 and kept sealed. The detection hood 320 may be connected to a driving cylinder, which may be vertically arranged to drive the detection hood 320 up and down. The floating steam may pass through the diaper to enter the detection hood 320.

As shown in fig. 2, in the present embodiment, the second valve 700 is disposed at a communication position between the spray head 330 and the water pipe 500, and is configured as a three-way valve. Which can control at least the upstream communication of the spray head 330 with the water conduit 500 so that the water conduit 500 supplies water to the spray head 330, thereby causing the spray head 330 to spray water; it is also possible to control the upstream of the water pipe 500 to communicate directly with the downstream of the water pipe 500 such that the water pipe 500 stops supplying water to the spray head 330, thereby stopping the spray head 330 from spraying water.

It can be appreciated that the present embodiment can achieve the purpose of preparing steam in the steam hood 310 by spraying water to the heater 340 through the spray head 330 communicated with the water pipe 500, so as to perform effective air permeability detection on the diaper.

More specifically, the spraying screen 410 is provided with a plurality of spraying holes, the rack 100 is provided with a placement table 420 for arranging paper diapers, the spraying holes face the placement table 420, the spraying screen 410 is communicated with the water pipeline 500, a third valve 800 is arranged at the communicating position, the third valve 800 is a three-way valve and is at least used for controlling the spraying screen 410 to be communicated to the upstream of the spraying screen 410 and controlling the upstream of the water pipeline 500 to be communicated to the downstream of the water pipeline 500.

As shown in fig. 2, in the present embodiment, it is exemplarily illustrated that the horizontal cross sections of the shower screen 410 and the loading table 420 may each be set to be rectangular and have an area larger than that of the diaper when it is unfolded. A number of spray holes may be uniformly distributed in an array on the spray screen 410 for spraying water. The placement table 420 is used for arranging paper diapers when unfolded, and is arranged right below the shower screen 410. When the spraying holes spray water, the water can be directly sprayed on the unfolded paper diaper. While the third valve 800 functions substantially the same as the second valve 700 for controlling upstream communication of the shower screen 410 with the water conduit 500 so that the water conduit 500 can supply water to the shower screen 410; and an upstream for the water conduit 500 is directly connected to a downstream of the water conduit 500 such that the shower screen 410 stops spraying water. The third valve 800 is disposed at a communication position of the shower screen 410 and the water pipe 500, and the shower screen 410 may communicate with the water pipe 500 through the second branch pipe 411, i.e., the third valve 800 is disposed at a connection position of the second branch pipe 411 and the water pipe 500. The second manifold 411 may also be provided with a flow meter 412, the flow meter 412 being used to detect the flow of water into the shower screen 410.

It can be appreciated that the present embodiment facilitates the detection of the water absorption of the diaper by communicating the shower screen 410 with the water pipe 500 while providing the third valve 800 for controlling the shower state of the shower screen 410.

More specifically, the elastic bladder 210, the shower head 330, and the shower screen 410 are sequentially disposed in communication with the water pipe 500 in a direction from an upstream side of the water pipe 500 toward a downstream side of the water pipe 500.

As shown in fig. 2, in the present embodiment, it is exemplarily illustrated that the connection point of the elastic bladder 210 and the water pipe 500 is close to the water inlet of the water pipe 500, the connection point of the shower screen 410 and the water pipe 500 is close to the water outlet of the water pipe 500, and the connection point of the shower head 330 and the water pipe 500 is the middle of the water pipe 500.

It will be appreciated that by means of the control of the first valve 600, the second valve 700 and the third valve 800, and the arrangement of the positions of the elastic air bag 210, the spray head 330, the shower screen 410 and the water pipe 500, the following detection means can be realized: the elastic air bag 210 is controlled to be communicated to the upstream of the water pipe 500 through the first valve 600, and the water pipe 500 supplies water to the first branch pipe 211 once until the elastic air bag 210 is inflated to a designated volume, so as to complete the elasticity detection of the diaper. Then the first valve 600 controls the elastic air bag 210 to be communicated with the downstream of the water pipeline 500, and the second valve 700 controls the spray head 330 to be communicated with the upstream of the water pipeline 500, at this time, the water in the elastic air bag 210 flows through the first branch pipe 211 and the water pipeline 500 in sequence to the spray head 330 under the elastic force of the elastic air bag 210 so as to spray water; in this process, the elastic air bag 210 can pressurize the water, so that the atomization effect of the water sprayed from the spray head 330 is better and the formation of steam is facilitated; on the other hand, the speed of supplying water to the spray head 330 can be ensured to be more uniform, so that the phenomenon that steam is formed unevenly in different time periods due to uneven water spraying amount of the spray head 330 is avoided, and further, the problem that the permeability of the paper diaper cannot be accurately judged is avoided. Then, the upstream of the water pipe 500 is controlled to be directly communicated with the downstream of the water pipe 500 through the second valve 700, so that the spray head 330 stops spraying water; meanwhile, the upstream of the water pipeline 500 is controlled to be communicated with spraying through the third valve 800, and at the moment, water in the elastic air bag 210 enters the spraying screen 410 and is sprayed out from a plurality of spraying holes; in the process, the spraying process is still a relatively uniform process, so that the control of the spraying quantity can be accurately mastered, and the accurate judgment of the water absorption of the paper diaper is facilitated. After all the detection is completed, the upstream of the water pipeline 500 is directly communicated with the downstream of the water pipeline 500 through the third valve 800, so that all the water in the elastic air bag 210 can be discharged.

It is apparent that the foregoing detection method only needs the water pipe 500 to supply water once, and compared with the detection method of water pipe 500 to supply water for multiple times or continuously, the detection method not only saves the water consumption, but also achieves the purpose of detecting the air permeability and the water absorbability of the diaper more accurately, and also avoids the inconvenience of secondary cleaning caused by spraying excessive water to the outside of the detection mechanism.

More specifically, the diaper performance detection apparatus further includes a controller 900, and the controller 900 is electrically connected to the first valve 600, the second valve 700, and the third valve 800, and is configured to: controlling the communication states of the first valve 600, the second valve 700, and the third valve 800;

when the controller 900 controls the third valve 800, the controller 900 controls the water pipe 500 to be communicated with the upstream of the water pipe 500 before the controller 900 controls the shower screen 410 to be communicated with the upstream of the water pipe 500 and controls the third valve 800 to be closed at least twice in an intermittent cycle.

As shown in fig. 3, in the present embodiment, it is exemplarily illustrated that the controller 900 controls the communication states of the first valve 600, the second valve 700, and the third valve 800, wherein there are a plurality of cycle controls when the controller 900 controls the third valve 800. The upstream of the water pipe 500 is controlled to be communicated with the downstream of the water pipe 500 by the third valve 800, that is, before the water absorption detection of the diaper is completed. And the controller 900 controls the shower screen 410 to communicate with the upstream of the water pipe 500, that is, controls the shower screen 410 to spray water to the diaper. The controller 900 controls the third valve 800 to be closed, i.e., controls the shower screen 410 to stop spraying water, and the water in the elastic bladder 210 stops being discharged. And the intermittent circulation is controlled at least twice, the controller 900 controls the shower screen 410 to spray water to the diaper at least twice. The mode of detection of the water absorption of the diaper at this time is as follows: water is sprayed to the diaper for a plurality of times to observe whether the diaper completely absorbs water each time and the duration of the water completely absorbed each time.

It can be appreciated that, in this embodiment, through reasonable control of the third valve 800, the spraying screen 410 can spray water to the diaper for multiple times, so as to divide the water spraying amount, and the condition of the water absorbing amount of the diaper in different water absorbing rotation states can be obtained, so that the water absorbing property of the diaper can be obtained more accurately.

More specifically, the controller 900 controls the shower screen 410 to communicate with the upstream of the water pipe 500 through the third valve 800 at least twice for equal periods of time.

In the present embodiment, it is exemplarily illustrated that when the controller 900 controls the third valve 800, the controller 900 controls the duration in which the shower screen 410 is communicated to the upstream of the water pipe 500, that is, controls the duration in which the shower screen 410 sprays water to the diaper. In this embodiment, therefore, the spraying screen 410 sprays water to the diaper for a plurality of times for equal periods of time.

Specifically, the detection cover 320 is transparent, and a plurality of detection transverse lines 321 are arranged on the inner side wall, the detection transverse lines 321 are arranged at intervals along the vertical direction, and the detection transverse lines 321 are composed of a plurality of powder which changes color when meeting water.

As shown in fig. 2 and 4, in the present embodiment, it is exemplarily illustrated that the detection cross lines 321 may be provided in a ring shape and may be attached to the inner sidewall of the detection cover 320 by electrostatic adsorption, and the detection cover 320 may be made of a colorless and transparent glass material. The powder that changes color when exposed to water may be anhydrous copper sulfate, which changes color blue when exposed to water. When the steam in the steam cover 310 passes through the paper diaper and enters the detection cover 320, the steam is liquefied into water when encountering cold, so that the detection transverse lines 321 are discolored.

It can be appreciated that, in this embodiment, by setting the detection transverse lines 321 and setting the detection cover 320 to be transparent, it is convenient to directly observe whether steam is generated in the detection cover 320, which is more visual and more accurate; meanwhile, by observing the color change of the detection cross lines 321 at different height positions, the amount of steam in the detection cover 320 can be conveniently judged, so that the excellent degree of the air permeability of the diaper can be obtained.

Specifically, the steam cover 310 and the detecting cover 320 are provided with a storage flange 350 at the ends close to each other, and the diaper is clamped between the two storage flanges 350 when the diaper is subjected to air permeability detection.

In the present embodiment, it is exemplarily illustrated that the storage flange 350 may be provided in a rectangular shape, and the center thereof may be the center of the steam hood 310 and the detection hood 320. The area of the object placing flange 350 is larger than the area of the paper diaper when the paper diaper is unfolded, and the two object placing flanges 350 clamp and fix the unfolded paper diaper so as to detect the air permeability of the paper diaper.

It can be appreciated that the paper diaper is clamped by the placement flange 350 in this embodiment, so that the paper diaper is not only clamped and fixed, but also kept airtight with the steam cover 310 and the detection cover 320.
