Description

Technical Field

[0001] This utility model relates to the field of paper contact angle measurement, specifically a sample pretreatment stage device for paper-water contact angle testing. Background Technology

[0002] In materials science and surface physics, contact angle testing is a crucial technique for evaluating the hydrophilicity, hydrophobicity, and other properties of materials. However, existing paper contact angle testing methods often face the problem of uneven surface baselines. Due to the characteristics of paper's fiber structure, once wetted, paper readily absorbs water and wrinkles, leading to difficult and inaccurate contact angle readings.

[0003] Traditional processing methods typically require complex pretreatment of the paper, such as applying a leveling layer or using special paper. This not only increases the difficulty of operation but may also cause test results to deviate from the true values. In addition, existing testing equipment often lacks optimization for paper characteristics, resulting in low testing efficiency.

[0004] Therefore, this utility model provides a sample pretreatment stage device for testing the contact angle between paper and water to solve the above problems. Utility Model Content

[0007] A bubble level is also provided on one side of the sample stage for leveling the worktable.

[0008] Preferably, the worktables on both sides of the sample stage are provided with mounting slots, and lifting cylinders are provided in the mounting slots. The output end of the lifting cylinders is connected to the annular cutter by screws.

[0009] Preferably, the workbench sidewall is provided with a control panel, which is connected to the tension sensor, linear motion slide, telescopic rod, and lifting cylinder via electrical signals.

[0010] Preferably, each of the four corners of the bottom of the workbench is provided with an electrically retractable table leg, and each electrically retractable table leg is connected to the control panel via an electrical signal.

[0011] Preferably, the inner diameter of the annular cutter is smaller than the diameter of the adhesive surrounding the sidewall of the sample stage.

[0012] Preferably, the sample stage is made of stainless steel, and the top of the workbench is provided with a groove for placing the sample stage.

[0013] Preferably, the annular cutter is made of stainless steel.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention provides a simple, efficient, and easy-to-operate paper pretreatment process. The sample stage is equipped with clips around its perimeter to hold the paper, and a tension sensor inside monitors the paper tension in real time. The distance between the clips and the sample stage can be controlled via a control panel, thus controlling the paper tension and ensuring it lies flat on the sample stage with adhesive.

[0019] A preferred embodiment of the present invention will now be described in conjunction with the accompanying drawings, providing a clear and complete description of the technical solution in this preferred embodiment.

[0020] A sample pretreatment stage device for testing the contact angle between paper and water includes: a workbench 1, a sample stage 2 on the top of the workbench 1, adhesive 21 surrounding the side wall of the sample stage 2, a tension sensor for real-time monitoring of paper tension changes, multiple inclined track grooves 3 around the sample stage 2, a linear motion slide 31 installed in the inclined track grooves 3, a telescopic rod 4 installed on the sliding plate of the linear motion slide 31, the output end of the telescopic rod 4 pointing vertically upward and equipped with a clamp 5 for gripping paper, and an annular cutter 6 above the sample stage 2, the inner diameter of the annular cutter 6 being smaller than the outer diameter of the sample stage 2, and both ends of the annular cutter 6 being connected to a lifting cylinder 8 set on the workbench 1.

[0021] A bubble level 7 for leveling the worktable 1 is also provided on one side of the sample stage 2.

[0022] This invention, through the above design, adjusts the bubble in the bubble level 7 to the center circle. The paper to be tested is clamped by the four clips 5. The tension is controlled by adjusting the sliding position of the linear motion slide 31, ensuring the paper is flat. Next, the telescopic rod 4 controls the four clips 5 to slowly lower the paper onto the sample stage 2. The paper is laid flat on top of the sample stage 2, with the four clips 5 located on the outside of the sample stage 2. The tension sensor inside the sample stage 2 monitors the tension changes of the paper in real time. Once the estimated tension value is reached, the sliding plate of the linear motion slide 31 is stopped, and the paper located on the outside of the sample stage 2 is gently pressed, making the paper firmly adhere to the adhesive 21 on the side wall of the sample stage 2. The lifting cylinder 8 is used to press down the annular cutter 6 to cut the paper. After cutting, the lifting cylinder 8 moves the annular cutter 6 to a higher position and fixes it. The sample stage 2 is then removed, and the contact angle test can be performed directly.

[0023] Specifically, mounting slots 11 are provided on the worktables 1 located on both sides of the sample stage 2. Lifting cylinders 8 are provided in the mounting slots 11, and the output end of the lifting cylinders 8 is connected to the annular cutter 6 by screws.

[0024] Through the above design, this utility model utilizes automated equipment for cutting, resulting in more uniform force distribution and flatter paper cuts.

[0025] Specifically, the workbench 1 is provided with a control panel 22 on its side wall. The control panel 22 is connected to the tension sensor, the linear motion slide 31, the telescopic rod 4, and the lifting cylinder 8 via electrical signals.

[0026] Through the above design, the tension sensor is used to monitor the tension changes of paper in real time, and can convert these changes into electrical signals for processing and display on the control panel 22. The position of the sliding plate of the linear motion slide 31 can be adjusted through the control panel 22, thereby adjusting the distance between the telescopic rod 4 and the clamps 5 and the sample stage 2, so as to realize the automatic adjustment of the tension of the four clamps 5 when gripping the paper.

[0027] Specifically, each of the four corners of the bottom of the workbench 1 is provided with an electric telescopic table leg 12, and each electric telescopic table leg 12 is connected to the control panel 22 via an electrical signal.

[0028] Through the above design, this utility model can automatically level the workbench 1 by controlling the extension height of each electric telescopic table leg 12 through the control panel 22.

[0029] Specifically, the diameter of the adhesive 21 surrounding the side wall of the sample stage 2 is larger than the inner diameter of the annular cutter 6.

[0030] Specifically, the sample stage 2 is made of stainless steel, the annular cutter 6 is made of stainless steel, and the top of the workbench 1 is provided with a groove for placing the sample stage 2.

[0031] Through the above design, the sample stage 2 has its own weight, and the worktable 1 has a groove for placing the sample stage 2, which prevents cutting errors caused by the sliding displacement of the sample stage 2 when cutting paper.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
