Abstract
Description
Technical Field
[0001] This application relates to the field of felt density measuring devices, and in particular to a portable felt density measuring device. Background Technology
[0002] In the monocrystalline silicon production sector of the photovoltaic industry, although graphite felt and cured felt are not major components of the thermal field, their annual consumption is considerable. Assuming a single furnace consumes 180 kg per month, a facility with over 1000 crystal pulling furnaces could spend 2.16 million yuan annually on graphite felt. Therefore, controlling the quality of the felt is crucial, and rigorous quality inspection must be implemented during the material receiving inspection stage.
[0003] However, the softness and extensibility of soft felt make it difficult to standardize the cutting process. This makes it challenging to ensure consistent volume in each cut, leading to measurement errors in sample volume and affecting the final mass-to-volume ratio (M / V). Furthermore, when large quantities of soft felt are inspected, the time wasted in the sample cutting process is significant. Samples cannot be tested immediately after cutting; all samples must be cut and weighed to calculate density. This process can lead to sample confusion, resulting in inaccurate and unreliable data.
[0004] Therefore, a portable felt density meter needs to be designed to solve the above problems. Utility Model Content
[0005] In view of this, in order to overcome the shortcomings of the prior art, this utility model provides a portable felt density meter, which effectively solves the problems of existing soft felt making it difficult to ensure that the volume remains consistent with each cut, the significant time wasted in the sample cutting process, and the inability to immediately test the sample after cutting.
[0006] According to the present invention, a portable felt density meter includes a cutting section and a measuring section. The cutting section is slidably disposed on the measuring section in a vertical direction. The measuring section includes a placement component and a measuring component. The placement component is disposed on the upper part of the measuring component. The cutting section includes a cutting component facing the placement component. When measuring the density of a felt sample, the felt sample is placed on the placement component, and the cutting component moves close to the placement component and cuts the felt sample to obtain a standard sample. The standard sample is measured by the measuring component.
[0007] Preferably, the placement component includes a support member disposed on the upper part of the metering component, and the support member internally accommodates a spring member.
[0008] Preferably, the cutting assembly includes a slider, the first end of which passes through the support member and abuts against the spring member.
[0009] Preferably, the outer wall of the support member is provided with a limiting groove, and the first end of the sliding member is provided with a limiting block, which is disposed in the limiting groove.
[0010] Preferably, there are multiple support members, which are spaced apart from each other on the upper part of the metering component. There are also multiple sliding members, which are arranged in a one-to-one correspondence with the multiple support members.
[0011] Preferably, two adjacent support members are connected by support plates, and multiple support plates surround the upper part of the metering component to form a cutting space.
[0012] Preferably, the placement assembly further includes a first cutting member and a fixing member, the first cutting member being disposed in the middle of the cutting space, the fixing member being disposed on the side of the first cutting member, and the first cutting member being connected to the support plate through the fixing member.
[0013] Preferably, the cutting part further includes a top cover, and the sliding member is disposed on the side of the top cover facing the support member.
[0014] Preferably, the cutting assembly further includes a second cutting member, which is disposed at the center of the side of the top cover facing the support member, and the second cutting member faces the first cutting member.
[0015] Preferably, the metering component includes a weighing platform and a metering device, the weighing platform being disposed above the metering device, the weighing platform being used to receive the standard sample, and the metering device being used to calculate the density of the standard sample.
[0016] According to this utility model, a portable felt density meter, through the cooperation of the cutting and measuring parts, allows felt samples to be cut into standard samples of uniform specifications. The density of the felt sample is then determined by the measuring part. Because this portable felt density meter has a regular overall structure and small size, it is easy for users to carry and can measure felt samples anytime, anywhere. Since standard samples can be obtained through cutting, the original shape and specifications of the felt samples are not limited while ensuring measurement accuracy, thus achieving universality in felt sample density measurement. This portable felt density meter integrates cutting, weighing, and measuring, enabling rapid measurement of large quantities of felt samples. It solves the drawback of existing methods that require waiting for all samples to be cut before density measurement, avoiding sample confusion and ensuring the accuracy and authenticity of the measurement.

[0027] According to the present invention, a portable felt density meter is provided, such as... Figures 1 to 3 As shown, the portable felt density meter is used for density measurement of soft felt components such as graphite soft felt and cured felt. The portable felt density meter includes a cutting part 1 and a measuring part 2.
[0028] In the following description, reference will be made to Figures 1 to 3 The detailed structure of the cutting section 1 and measuring section 2 of the portable felt density meter is described in detail.
[0029] like Figures 1 to 3 As shown, in this embodiment, the cutting part 1 is slidably disposed on the measuring part 2 in the vertical direction, where the vertical direction can be understood as... Figure 1 The vertical direction within. Furthermore, the overall shape of the cutting section 1 and the measuring section 2 can be formed as an approximately cuboid structure. The placement components and cutting components described below are all located inside the cuboid structure. This makes the overall structure of the portable felt density meter regular and small in size, easy to carry, and allows users to measure the density of felt samples (not shown, felt samples can be common soft felt parts) anytime and anywhere.
[0030] Furthermore, the measuring unit 2 may include a placement component and a measuring component. The placement component is used to place the felt sample so as to facilitate cutting with the cutting unit 1. The measuring component enables rapid density measurement of the cut felt sample. Specifically, the placement component is located on top of the measuring component, and the placement component needs to cooperate with the cutting unit 1 to cut the felt sample.
[0031] Furthermore, the cutting section 1 includes a cutting component facing the placement component. When measuring the density of a felt sample, the felt sample is placed on the placement component, and the cutting component approaches the placement component to cut the felt sample to obtain a standard sample. The standard sample is then measured by the measuring component. The cutting component's proximity to the placement component can be understood as follows: since the cutting section 1 is slidably mounted vertically on the measuring section 2, the user can push the cutting section 1 closer to the measuring section 2, causing the cutting component and the placement component to come into contact, cutting the felt sample on the placement component to obtain a standard sample with uniform specifications. The cut standard sample falls onto the measuring component, which can then weigh the standard sample. Since the thickness of each batch of felt samples is uniform, the density of the standard sample can be calculated based on its weight and shape.
[0032] This portable felt density meter, through the cooperation of the cutting section 1 and the measuring section 2, allows felt samples to be cut into standard samples of uniform size, and then the density of the felt sample is finally obtained through the measurement by the measuring section 2. Because of its neat overall structure and small size, this portable felt density meter is easy for users to carry and can measure felt samples anytime, anywhere. Since standard samples can be obtained through cutting, the original shape and size of the felt sample can be used without restriction while ensuring measurement accuracy, thus achieving universality in felt sample density measurement. This portable felt density meter integrates cutting, weighing, and measuring, enabling rapid measurement of large quantities of felt samples. It solves the drawback of existing measurements that require waiting for all samples to be cut before density measurement, avoiding sample confusion and ensuring the accuracy and authenticity of the measurement.
[0033] Preferably, such as Figure 1 and Figure 3 As shown, in this embodiment, the placement component may include a support member 301, which is disposed on the upper part of the metering component. A spring member 302 is housed inside the support member 301. The support member 301 can support the cutting part 1, and the spring member 302 can cause the cutting part 1 to return to its original position. Specifically, the support member 301 can be formed as a pillar structure, such as a cuboid pillar, with a hollow interior to accommodate the sliding member 501 and the spring member 302.
[0034] Preferably, such as Figures 1 to 3 As shown, in this embodiment, the cutting assembly may include a slider 501, the first end of which passes through the support member 301 and abuts against the spring member 302. The slider 501 can be understood as a telescopic rod, capable of extending and retracting vertically within the support member 301 and returning to its original position via the spring member 302.
[0035] Preferably, such as Figure 2 and Figure 3 As shown in the embodiment, a limiting groove 303 is formed on the outer wall of the support member 301, and a limiting block 502 is provided at the first end of the sliding member 501. The limiting block 502 is disposed in the limiting groove 303. In order to ensure smooth and stable sliding, it is necessary to additionally provide the limiting block 502 and the limiting groove 303.
[0036] Preferably, such as Figure 2 and Figure 3 As shown, in this embodiment, there are multiple support members 301, which are spaced apart and arranged on the upper part of the metering component. Specifically, in this embodiment, there are four support members 301, which are respectively arranged at the four corners of the metering component. The four support members 301 also allow the metering part 2 to have a shape close to a cuboid, improving portability. Correspondingly, there are multiple sliders 501, which are arranged one-to-one with the multiple support members 301.
[0037] Preferably, such as Figure 1 and Figure 3 As shown, in this embodiment, two adjacent support members 301 are connected by support plates 304, and multiple support plates 304 surround the upper part of the metering component to form a cutting space. The support plates 304 can be formed as cuboid plates. Since there are four support members 301 in this embodiment, there are also four support plates 304. The four support plates 304 are connected end to end to form a cutting space. The cutting space can be used to accommodate felt samples to be cut, and also to accommodate standard samples after cutting, so that the standard samples can be weighed directly.
[0038] Preferably, such as Figure 1 and Figure 3 As shown, in the embodiment, the placement component may further include a first cutting member 305 and a fixing member 306. The first cutting member 305 is disposed in the middle of the cutting space. The first cutting member 305 may be formed into a circular structure. The standard sample cut out in this way may be formed into a disc shape. The density can be calculated based on the thickness and diameter of the disc-shaped standard sample and the weight of the standard sample.
[0039] Furthermore, the fastener 306 is disposed on the side of the first cutting member 305. The fastener 306 can be, for example, a combination of screws, nuts and washers. Since the first cutting member 305 is formed into a ring structure, in order to ensure the stability of the first cutting member 305, there are multiple fasteners 306, specifically four. The first cutting member 305 is connected to the four support plates 304 one by one through the four fasteners 306.
[0040] Preferably, such as Figure 1 and Figure 2 As shown, in this embodiment, the cutting section 1 may further include a top cover 6, and a slider 501 is disposed on the side of the top cover 6 facing the support member 301. The user can push the top cover 6 to bring the cutting section 1 closer to the measuring section 2.
[0041] Preferably, such as Figure 1 and Figure 2 As shown, in this embodiment, the cutting assembly may further include a second cutting member 503, which is disposed in the middle of the side of the top cover 6 facing the support member 301, and faces the first cutting member 305. The shape of the second cutting member 503 needs to correspond to the shape of the first cutting member 305 so that a disc-shaped standard sample can be cut out, thereby facilitating subsequent density measurement.
[0042] Preferably, such as Figure 1 and Figure 3 As shown, in this embodiment, the metering component may include a weighing platform 401 and a metering device 402. The weighing platform 401 is disposed above the metering device 402. The weighing platform 401 is used to receive the standard sample, and the metering device 402 is used to calculate the density of the standard sample. Both the weighing platform 401 and the metering device 402 can be common components used for weighing and calculation in the prior art. After the standard sample is cut, it falls onto the weighing platform 401. The weighing platform 401 feeds back the weighing value to the metering device 402. The metering device 402 calculates the density of the standard sample based on the previously determined diameter and thickness of the standard sample and the weighing value.
[0043] The portable felt density meter is used as follows: A felt sample (including small pieces of soft felt and small pieces of solid felt, etc.) is placed on the first cutting piece 305. Then, the top cover 6 is pushed, causing the second cutting piece 503 to approach the first cutting piece 305 and cut the felt sample to obtain a standard sample. Afterward, the external force is removed, and the spring 302 returns to its original length, causing the cutting part 1 to reset. The cut standard sample falls onto the weighing platform 401 for weighing. Since the thickness of each batch of felt samples is consistent, for example, 10 mm, and the diameter of the first cutting piece 305 is also fixed (80 mm in this embodiment), the volume of the cut standard sample is 50.265 cm³. 3If the mass M obtained through weighing platform 401 is used, then the density of the standard sample is: M / 50.265.
[0044] This portable felt density meter, through the cooperation of its cutting and measuring sections, allows felt samples to be cut into standard samples of uniform size. The density of the felt sample is then determined by the measuring section. Due to its compact and well-organized structure, this portable felt density meter is easy for users to carry, enabling measurements of felt samples anytime, anywhere. Because standard samples can be obtained through cutting, the original shape and specifications of the felt samples are not restricted, ensuring measurement accuracy and achieving universality in felt density measurement. This portable felt density meter integrates cutting, weighing, and measuring, allowing for rapid measurement of large quantities of felt samples. It overcomes the drawback of existing methods that require waiting for all samples to be cut before density measurement, avoiding sample confusion and ensuring the accuracy and reliability of the measurement.
