Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric quality testing, and more specifically, to a waterproof testing device for waterproof high-strength composite nonwoven fabric. Background Technology

[0002] Waterproof, high-strength composite nonwoven fabric has superior performance and can be used in a variety of environments.

[0003] In the waterproof testing of our company's nonwoven fabrics, one of the tests is an immersion test. The specific operation steps are as follows: take a piece of nonwoven fabric, measure its weight in a dry state, then immerse it in water, remove the nonwoven fabric, wipe off the excess water on the surface, avoid squeezing, and measure its weight again. By comparing the two weights, the immersion test result of the nonwoven fabric is obtained.

[0004] In the above experiment, it is necessary to manually use paper towels or handkerchiefs to remove excess water from the non-woven fabric. Although this is convenient, the process of manually laying out paper towels first, then non-woven fabric, and then paper towels again is relatively troublesome. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a waterproof and high-strength composite nonwoven fabric waterproof testing device. The technical problem to be solved by the present invention is: how to improve the convenience of laying paper towels and ensure that both the top and bottom sides of the nonwoven fabric are covered with paper towels for water absorption.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waterproof and high-strength composite nonwoven fabric waterproof testing device, comprising a weighing component arranged on a workbench; a support mechanism comprising a base and a support rod, the base being arranged on the workbench, the support rod being fixedly connected to the base, a roll of paper towel being sleeved on the support rod, the side wall of the weighing component being fitted against the base, and the side wall of the weighing component being parallel to the axis of the support rod; and a smoothing mechanism comprising a slider and a smoothing component, the slider being slidably connected to the side wall of the weighing component, the smoothing component being connected to the slider, and the smoothing component being used to move along the weighing surface of the weighing component.

[0007] In a preferred embodiment, the smoothing component includes a spacing adjustment rod and a smoothing plate. One end of the spacing adjustment rod is fixedly connected to the smoothing plate, and the other end is vertically slidably connected to the slider damper. The smoothing plate is horizontally positioned above the weighing surface of the weighing component.

[0008] In a preferred embodiment, the smoothing mechanism further includes a shrink housing and a coil spring, the shrink housing being detachably connected to one side of the weighing member, one end of the coil spring being fixedly connected to the shrink housing and the other end being fixedly connected to the slider.

[0009] In a preferred embodiment, the shrinkable shell and the sidewall of the weighing component are connected by magnetic attraction.

[0010] In a preferred embodiment, the support mechanism further includes a compensating rod and a stop rod, the compensating rod and the support rod being coaxially elastically slidably connected, and the outer end of the compensating rod and the stop rod being damped rotatably connected.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] This application mainly improves the convenience of changing paper towels by designing the positional relationship between the weighing component and the support mechanism and applying the roll-shaped paper towels into the whole. In addition, by designing a smoothing mechanism, the smoothing mechanism is more uniform than manual smoothing, which can reduce the error caused by excessive or insufficient water absorption in the measurement results.

[0020] Example

[0021] like Figures 1-3 A waterproof and high-strength composite nonwoven fabric waterproof testing device includes a weighing component 1, a support mechanism 2 and a smoothing mechanism 3. The weighing component 1 is electrically connected to an external controller for controlling the timing of weighing by the weighing component 1 under manual operation and uploading the weighed data to the external controller.

[0022] Weighing component 1 is an electronic scale.

[0023] Support mechanism 2 serves to support the paper towel.

[0024] The smoothing mechanism 3 is used to evenly control the removal of excess moisture from the non-woven fabric surface by the paper towel.

[0025] The support mechanism 2 includes a base 21 and a support rod 22. The base 21 and the weighing component 1 are placed together on the workbench. The support rod 22 is fixed on the base 21. The roll of paper towel is put on the support rod 22. The user can use this to quickly pull the paper towel and tear it off and discard it after using part of the paper towel. It is convenient and quick, without the user having to lay out the paper towel first and then move the non-woven fabric to the center of the paper towel.

[0026] The smoothing mechanism 3 includes a slider 31 and a smoothing component 32. The slider 31 is slidably connected to the side wall of the outer shell of the weighing component 1. The smoothing component 32 includes a spacing adjustment rod 321 and a smoothing plate 322. The smoothing plate 322 is placed horizontally on the weighing surface of the weighing component 1 for smoothing the paper towel. One end of the spacing adjustment rod 321 is fixedly connected to the smoothing plate 322, and the other end is vertically damped and slidably connected to the slider 31. By manually adjusting the position of the spacing adjustment rod 321 relative to the slider 31, the distance between the smoothing plate 322 and the paper towel is adjusted so that the force of the smoothing plate 322 when smoothing the paper towel is just right.

[0027] In practical applications, the weight of the nonwoven fabric in its dry state is first obtained. Then, the roll of paper towel inside the support mechanism 2 is pulled, and the paper towel is allowed to pass over the weighing surface of the weighing device 1 and extend outwards. After that, the nonwoven fabric that has been soaked for a sufficient time is taken out of the soaking tank. The nonwoven fabric is then placed on the paper towel located on the weighing surface of the weighing device 1 using tweezers. The extended paper towel is folded over and covered on the nonwoven fabric. In this way, paper towels are placed on both the top and bottom sides of the nonwoven fabric to absorb moisture. At this time, the smoothing plate 322 with the pre-adjusted spacing is moved above the folded area. By moving the smoothing plate 322, the user can use its smoothing effect to evenly absorb the moisture from the surface of the nonwoven fabric using the paper towel. After that, the used paper towel is torn off and removed from the weighing surface of the weighing device 1. At this time, the weighing device 1 is controlled to weigh the nonwoven fabric that has had its surface moisture removed to obtain the weight after the soaking test. Substituting the weight into the relevant formula, the soaking water resistance of the nonwoven fabric can be obtained.

[0028] Preferably, the support mechanism 2 further includes a compensating rod 23 and a stop bar 24. The support rod 22 has a hollow structure, and the compensating rod 23 passes through the support rod 22. The support rod 22 and the compensating rod 23 are elastically slidably connected, and the stop bar 24 is rotatably connected to the outer end of the compensating rod 23. When the axes of the compensating rod 23 and the stop bar 24 are collinear, a roll of tissue paper is placed on the support rod 22, and then the stop bar 24 is rotated. By pulling the compensating rod 23, the stop bar 24, which has an angle with the compensating rod 23, serves to limit the side wall of the roll. On the one hand, the extensibility of the compensating rod 23 allows the support mechanism 2 to clamp rolls of different lengths; on the other hand, the limiting effect of the stop bar 24 can improve the stability of the roll located on the support rod 22.

[0029] Preferably, friction damping is fixed on the rotating surfaces of the compensating rod 23 and the stop rod 24.

[0030] Preferably, the shrink shell 33 is detachably connected to one side of the weighing member 1 by magnetic attraction. A coil spring is wound inside the shrink shell 33, and one end of the coil spring is fixedly connected to the slider 31. After the manual removal from the slider 31, the slider 31 can automatically return to the end of the weighing member 1 without affecting the placement process of the non-woven fabric.

[0031] Working principle of this utility model:

[0032] This application mainly improves the convenience of changing paper towels by designing the positional relationship between the weighing component 1 and the support mechanism 2 and applying the roll-shaped paper towels into the whole. In addition, by designing the smoothing mechanism 3, compared with the manual smoothing operation, the smoothing mechanism 3 is more uniform and can reduce the error caused by excessive or insufficient water absorption to the measurement results.
