Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the technical field of paper thickness measuring instruments, and more specifically, to a paper thickness measuring instrument that is easy to fix. Background Technology
[0002] In the paper manufacturing, printing, and packaging industries, paper thickness is a crucial indicator of paper quality, directly impacting its performance, usability, and overall product quality. Accurate paper thickness measurement is essential for controlling production processes and ensuring product compliance with quality standards. However, existing paper thickness measuring instruments suffer from numerous problems in practical use, severely affecting the accuracy and efficiency of measurements.
[0003] First, existing paper thickness measuring instruments have shortcomings in fixing the paper. It is difficult to ensure that the paper remains flat and stable throughout the measurement process, and the paper is prone to shaking or displacement, resulting in inaccurate measurement data that cannot accurately reflect the paper thickness.
[0004] Secondly, existing measuring instruments struggle to perform continuous multi-location measurements. In actual production, paper thickness may be uneven, requiring measurements at multiple locations to comprehensively understand the thickness distribution. However, traditional measuring instruments often only allow single-point measurements. Measuring multiple locations necessitates repeated adjustments by the operator, a cumbersome and time-consuming process. Furthermore, ensuring consistent measurement conditions during multiple adjustments further impacts the accuracy and comparability of the results, hindering the provision of comprehensive and reliable data support for production process optimization.
[0005] With the increasing demands for paper quality in the paper industry and the gradual improvement of production automation, the shortcomings of traditional paper thickness gauges in fixing paper and continuous measurement at multiple locations are becoming increasingly apparent. Developing a paper thickness gauge that can easily fix paper and achieve continuous measurement at multiple locations is urgently needed, as it has significant practical implications for improving paper quality, optimizing production processes, and enhancing the market competitiveness of enterprises. Utility Model Content
[0006] To overcome the above-mentioned defects, the embodiments of this disclosure provide a paper thickness measuring instrument that is easy to fix, which solves the technical problems of inconvenience in fixing during the measurement process and inability to continuously measure at multiple positions in the prior art.
[0007] According to one aspect, at least one embodiment of this disclosure provides a conveniently fixed paper thickness measuring instrument, comprising:
[0008] The base frame and the main body of the measuring instrument are mounted on the base frame;
[0009] The platform and the movable adjustment component are provided, wherein the platform is fixed inside the base frame and the movable adjustment component is disposed between the platform and the main body of the measuring instrument.
[0010] A positioning component, wherein the positioning component is disposed on the base frame and the platform;
[0011] The positioning component includes a pair of rolling rods, both of which are rotatably connected to the inner side of the base frame. A pair of movable cavities are opened at the upper end of the base frame, and a pair of round rods are arranged in the movable cavities. A slider is slidably connected to the round rod, and a first spring is fitted on each round rod. A downward pressure rod is rotatably connected to the side end face of the slider.
[0012] As a further technical solution, a crossbar is connected between the pressing rods, one end of one of the rolling rods is provided with an anti-slip block, a pair of rectangular openings are provided at both ends of the platform surface, and a pair of guide rods are provided at both ends of the bottom of the platform.
[0013] As a further technical solution, the guide rod is positioned corresponding to the rectangular opening, and both ends of the guide rod are slidably fitted with a sleeve. The sleeve has an overall L-shaped structure, and the upper end of the sleeve is located on the platform surface.
[0014] As a further technical solution, the movable adjustment assembly includes a top frame, which is fixed to the platform surface. A pair of sliding grooves are provided on the top frame, and the main body of the measuring instrument is slidably connected in the sliding grooves. Bolts are connected to the side end face of the main body of the measuring instrument by threaded connection.
[0015] As a further technical solution, a connecting frame is fixed inside the main body of the measuring instrument, and a measuring column is movably connected to the lower end of the connecting frame. A limiting layer is provided on the surface of the measuring column, and a second spring is fitted on the outside of the measuring column. The second spring is supported between the limiting layer and the connecting frame.
[0016] As a further technical solution, the upper inner surface of the sleeve is an inclined structural surface.
[0017] As a further technical solution, both the rolling rod and the pressing rod have anti-slip surfaces made of rubber.
[0018] As a further technical solution, the bottom surface of the measuring column is a smooth surface with low friction, and the right angle at the lower end of the measuring column is an arc-shaped transition structure.
[0019] The beneficial effects of the embodiments disclosed herein are as follows:
[0020] 1. The beneficial effect of the positioning component in this disclosure is that it effectively solves the problem of difficult paper fixation. The rolling rod provides stable support for the paper, and the anti-slip block can quickly fix the paper when needed to prevent it from rolling. The pressure bar and the crossbar work together to apply uniform and stable pressure to the paper under the action of the first spring, ensuring that the paper is placed flat. The rectangular opening, the guide rod, and the sleeve cooperate to limit the paper from both sides. These components work together to keep the paper stable during the measurement process, avoiding measurement errors caused by paper shaking or displacement, and greatly improving the accuracy of the measurement. Moreover, this fixing method is simple and convenient to operate, improving work efficiency.
[0021] 2. The beneficial effect of the movable adjustment component in this disclosure is that it enables flexible movement and precise positioning of the measuring instrument body. The slide groove on the top frame provides a precise moving track for the measuring instrument body, facilitating quick adjustment of the measuring position by the operator. The bolt design securely fixes the measuring instrument body after the position is adjusted, ensuring that the measuring instrument will not shift during the measurement process. The cooperation of the measuring column, the limiting layer, and the second spring allows the measuring column to automatically adjust the contact force according to the paper thickness, ensuring a tight fit with the paper and adapting to the measuring needs of paper of different thicknesses. Through the movable adjustment component, the operator can easily perform continuous measurements at multiple positions on the paper without repeatedly disassembling and reassembling the measuring instrument, simplifying operation, improving measuring efficiency, and providing convenience for a comprehensive understanding of the paper thickness distribution.

[0033] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0034] like Figures 1-4 As shown, it illustrates a conveniently fixed paper thickness measuring instrument according to an embodiment of the present disclosure, comprising:
[0035] The base frame 1 and the measuring instrument body 2 are mounted on the base frame 1.
[0036] Platform 3 and movable adjustment component 5, wherein platform 3 is fixed inside the base frame 1 and movable adjustment component 5 is disposed between platform 3 and the measuring instrument body 2;
[0037] Positioning component 4 is disposed on the base frame 1 and the platform 3;
[0038] The positioning component 4 includes a pair of rolling rods 4-1, each of which is rotatably connected to the inner side of the base frame 1. The upper end of the base frame 1 has a pair of movable cavities 4-2, and a pair of round rods 4-3 are arranged in the movable cavities 4-2. A slider 4-4 is slidably fitted on the round rods 4-3. A first spring 4-5 is fitted on each of the round rods 4-3. A pressing rod 4-6 is rotatably connected to the side end face of the slider 4-4. A crossbar 4-7 is connected between the pressing rods 4-6. One end of one of the rolling rods 4-1 is provided with an anti-slip block 4-8. A pair of rectangular openings 4-9 are opened at both ends of the surface of the platform 3. A pair of guide rods 4-10 are provided at both ends of the bottom of the platform 3. The guide rods 4-10 are positioned corresponding to the rectangular openings 4-9. A sleeve 4-11 is slidably fitted at both ends of the guide rods 4-10. The sleeve 4-11 has an overall L-shaped structure, and the upper end of the sleeve 4-11 is located on the surface of the platform 3.
[0039] In some examples, during paper thickness measurement, a positioning component 4 is designed to accurately limit the paper position and achieve convenient fixation. This component is based on a pair of rolling rods 4-1 rotatably connected to the inside of the base frame 1, which serve as a support for the paper movement. A pair of movable cavities 4-2 are opened at the upper end of the base frame 1, and a round rod 4-3 inside provides a sliding track for the slider 4-4. A first spring 4-5 fitted on the round rod 4-3 provides a reset force for the slider 4-4. A downward pressure rod 4-6 rotatably connected to the side end face of the slider 4-4 is connected to a crossbar 4-7, which can apply downward pressure to the paper to ensure that the paper is placed flat.
[0040] One of the rolling rods 4-1 has an anti-slip block 4-8 at one end. When a finger presses the anti-slip block 4-8, it can prevent the rolling rod 4-1 from rotating, thereby fixing the paper and preventing it from moving during the measurement process. The rectangular openings 4-9 at both ends of the surface of the platform 3 correspond to the guide rods 4-10 at both ends of the bottom. The L-shaped sleeves 4-11 that slide at both ends of the guide rods 4-10 have their upper ends located on the surface of the platform 3. They can limit the left and right boundaries of the paper. Together with the pressing rod 4-6 and the anti-slip block 4-8, they can restrict the position of the paper from multiple directions, achieving precise positioning and firm fixation of the paper.
[0041] Through the coordinated operation of components such as the rolling rod 4-1, the movable cavity 4-2, the round rod 4-3, the slider 4-4, the first spring 4-5, the pressing rod 4-6, the crossbar 4-7, the anti-slip block 4-8, the rectangular opening 4-9, the guide rod 4-10, and the sleeve 4-11, the positioning assembly 4 realizes the functions of limiting the paper position, adjusting left and right by pulling, and fixing the paper.
[0042] like Figures 1-4 As shown in the figure, the movable adjustment component 5 in this embodiment includes a top frame 5-1, which is fixed to the surface of the platform 3. A pair of sliding grooves 5-2 are provided on the top frame 5-1. The measuring instrument body 2 is slidably connected in the sliding grooves 5-2. A bolt 5-7 is threadedly connected to the side end face of the measuring instrument body 2. A connecting frame 5-3 is fixed to the inner side of the measuring instrument body 2. A measuring column 5-4 is movably connected to the lower end of the connecting frame 5-3. A limiting layer 5-5 is provided on the surface of the measuring column 5-4. A second spring 5-6 is fitted on the outside of the measuring column 5-4. The second spring 5-6 is supported between the limiting layer 5-5 and the connecting frame 5-3.
[0043] In some examples, during the paper thickness measurement process, a movable adjustment component 5 is designed to flexibly adjust the measuring position of the measuring instrument. This component is supported by a top frame 5-1 fixed to the surface of the platform 3. A pair of sliding grooves 5-2 on the top frame 5-1 provide a sliding track for the measuring instrument body 2, allowing the measuring instrument body 2 to move linearly on the top frame 5-1. The side end face of the measuring instrument body 2 is connected to the bolts 5-7 by threaded engagement, which can fix the measuring instrument body 2 on the top frame 5-1 after the measuring position is adjusted, preventing it from shifting during the measurement process.
[0044] The measuring instrument body 2 has a fixed connecting frame 5-3 inside, which is connected to the measuring column 5-4, which is movably mounted at the lower end. The upper end of the measuring column 5-4 contacts the output end of the measuring instrument body 2. The limiting layer 5-5 on the surface of the measuring column 5-4 and the second spring 5-6 mounted on the outside of the measuring column 5-4 cooperate with each other. When the measuring instrument body 2 moves to the target position, the measuring column 5-4 contacts the paper surface under the elastic force of the second spring 5-6. The elasticity of the second spring 5-6 can adapt to the measurement requirements of paper of different thicknesses, ensuring that the measuring column 5-4 fits tightly with the paper and achieves accurate measurement.
[0045] Through the coordinated operation of components such as the top frame 5-1, slide 5-2, bolt 5-7, connecting frame 5-3, measuring column 5-4, limiting layer 5-5, and second spring 5-6, the moving adjustment assembly 5 realizes the function of linearly moving to adjust the measuring position of the measuring instrument, meeting diverse paper thickness measuring needs.
[0046] For example, such as Figure 4 As shown, the inner upper surface of the sleeve 4-11 is an inclined structural surface.
[0047] In some examples, the inclined structural surface facilitates the insertion of paper and allows for quick positioning of the paper by clamping it.
[0048] For example, such as Figure 1 As shown, the surfaces of the rolling rod 4-1 and the pressing rod 4-6 are both made of rubber with anti-slip structure.
[0049] In some examples, the use of rubber material can increase the friction between the surfaces of the roller 4-1 and the pressure bar 4-6, ensuring that the paper is held in place.
[0050] For example, such as Figure 3 As shown, the bottom surface of the measuring column 5-4 is a smooth surface with low friction, and the lower right angle of the measuring column 5-4 has an arc-shaped transition structure.
[0051] In some examples, using a smooth surface with high friction does not impede paper movement or cause excessive friction on the paper to affect the test results.
[0052] In actual use: Place the paper to be measured on platform 3, so that the paper is above a pair of rolling rods 4-1. Press down the anti-sliding block 4-8 to prevent the rolling rods 4-1 from rotating and to initially fix the paper. At the same time, use the sleeve 4-11 on the guide rod 4-10 to limit the left and right boundaries of the paper. Then push the crossbar 4-7 so that the lower pressure rod 4-6 moves downward under the action of the slider 4-4 and the first spring 4-5, pressing the paper tightly to ensure that the paper will not shake or shift during the measurement. Next, loosen the bolt 5-7 on the side end face of the measuring instrument body 2 according to the required measurement position. Slide the measuring instrument body 2 to the target position in the slide groove 5-2 of the top frame 5-1. Then tighten the bolt 5-7 to fix the measuring instrument body 2. The measuring column 5-4 in the measuring instrument body 2 contacts the paper surface under the action of the second spring 5-6. During the process, the paper can be pulled left and right to perform multi-position measurement and measure the paper thickness. After the measurement is completed, release the lower pressure rod 4-6 and take out the paper. If other positions of the paper need to be measured, repeat the above operation.
[0053] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
