Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of sample detection, and in particular to a sample clamping support and a water immersion burst strength detection device. BACKGROUND

[0002] In industrial production, in order to ensure product quality, it is necessary to detect various indexes of raw materials, semi-finished products and finished products in time to ensure that qualified products can be produced. For example, in the paper and paper product production industry, the physical property indexes of raw paper, semi-finished paperboard or finished paper boxes need to be detected to reflect the physical properties of paper, paperboard or paper boxes. As one of the many physical property indexes, the water immersion burst strength can reflect the physical properties of raw paper, semi-finished paperboard or finished paper boxes after being affected by severe and extreme weather conditions, but the detection difficulty is extremely high.

[0003] Whether the detection conditions are met and whether the detection method of the quality inspector is standardized have a very important influence on the detection results, and even affect the benign development of the entire industry. As an important basis for judging whether the physical property indexes of raw paper, semi-finished paperboard or finished paper boxes meet the standards, the water immersion burst strength detection process must have the basic conditions required by the national standards.

[0004] According to the current national standard GB / T 465.1-2008 8.1 requirements: When soaking the sample, the samples should be completely separated from each other and should not touch the bottom and edge of the water tank. The long edge of the sample is vertically immersed in water, and the upper edge of the sample is 25mm±2mm below the water surface. When the corrugated paper is immersed in water, the corrugated paper should be vertical to avoid air storage and affect the water absorption of the sample. After soaking for the specified time, take out the sample from the water, gently suck off the excess water, and immediately measure it.

[0005] Chinese invention patent CN111413269A discloses a sample soaking basket and a water immersion burst strength detection device, but it is difficult to find related products on the market, and the sample soaking basket and the water immersion burst strength detection device have the disadvantage of complex structure. Therefore, at present, there is still a lack of an auxiliary detection tool with simple structure, low cost and convenient use, so that most of the detection of the physical property indexes of raw paper, semi-finished paperboard or finished paper boxes needs to be completed manually. There are the following problems.

[0006] (1) When processing batch samples, manual adjustment of the gap is required to ensure that each sample is separated from each other and immersed in water at the same time.

[0007] (2) The sample will float up at the beginning of soaking due to buoyancy, and will sink at the end of soaking due to gravity. It is difficult for manual operation to keep the sample at 25mm±2mm below the water surface and not touch the bottom and edge of the water tank at all times.

[0008] (3) During the soaking process, it is difficult to keep the corrugations always perpendicular, which will cause poor exhaust and unsatisfactory soaking effect.

[0009] (4) The sample soaking basket and water immersion breaking strength detection device disclosed in Chinese invention patent CN111413269A has a relatively complex structure. The size of the space for accommodating the sample is fixed, and when processing samples of different thicknesses, it is difficult to achieve an ideal soaking effect under simple operation, thereby affecting the efficiency of sample processing and the accuracy of detection results. SUMMARY

[0018] In some embodiments, the end component (4) connected to the multi-link structure is arranged at a predetermined angle relative to the plane formed by the transverse axis and the longitudinal axis of the second multi-link structure (3).

[0019] In some embodiments, the middle connecting multi-link structure component (5) and the end connecting multi-link structure component (4) are configured to make the first multi-link structure (2) and the second multi-link structure (3) move in the same direction with a predetermined deformation amount during the stretching and contraction along the longitudinal axis direction of the second multi-link structure (3).

[0020] In some embodiments, the predetermined deformation amount is adaptively matched with the thickness of the sample (1) pretreated by the sample clamping support, for clamping the sample (1) and separating the space for accommodating the sample (1).

[0021] In some embodiments, the first multi-link structure (2) and the second multi-link structure (3) each include a plurality of groups of first and second links (71) and (72) connected end to end, the first and second links (71) and (72) are configured to have a predetermined length.

[0023] Some embodiments of the present disclosure provide a water immersion burst resistance detection device, which comprises the aforementioned sample clamping support for immersing a paperboard or paper sample into water.

The detection labor cost is reduced, and the pretreatment efficiency of the water immersion burst resistance detection sample and the accuracy of the sample detection result are greatly improved.

[0034] Embodiments of the present application will now be described in detail below, examples of which are shown in the accompanying drawings. The description of the exemplary embodiments is merely intended to be illustrative in nature and is not intended to limit the present disclosure, its application or uses in any way.

When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0036] In the present disclosure, when it is described that a specific device is located between a first device and a second device, there can be an intervening device between the specific device and the first device or the second device, or there can be no intervening device. When it is described that a specific device is connected to other devices, the specific device can be directly connected to other devices without an intervening device, or can not be directly connected to other devices with an intervening device.

[0037] In combination Figures 1-5 As shown in the drawings, some embodiments of the present disclosure provide a sample clamping support, comprising: a multi-link structure and a component connecting the multi-link structure, the multi-link structure comprising a first multi-link structure (2) and a second multi-link structure (3), and the component connecting the multi-link structure comprising a middle component connecting the multi-link structure (5), an end component connecting the multi-link structure (4), and a support component (6).

[0038] As Figure 1 shown, the support component (6) is configured at the bottom surface of the sample clamping support, which has the effect of maintaining a predetermined distance between the bottom surface of the sample clamping support and the horizontal plane, so that the sample and the bottom surface of the soaking container always maintain a predetermined distance, achieving sufficient exhaust and infiltration of the sample.

[0039] As Figure 1 and Figure 2As shown in the drawings, the second multi-link structure (3) is configured to bear the support load, thereby achieving the support and accommodation of the sample, the first multi-link structure (2) is arranged above the second multi-link structure (3) with reference to the second multi-link structure (3), which has the effect of limiting the sample from floating up and limiting the sample below the liquid level of the soaking solution, the first multi-link structure (2) and the second multi-link structure (3) are connected by the middle connecting multi-link structure component (5) and the end connecting multi-link structure component (4) at a predetermined interval, which has the effect of connecting the first multi-link structure (2) and the second multi-link structure (3) as a whole and maintaining a predetermined interval, facilitating more effective accommodation of the sample (1) and convenient taking of the sample (1).

[0040] As shown in the drawings, Figure 1 , Figure 2 and Figure 3 , the end connecting multi-link structure component (4) is perpendicular to the plane formed by the transverse axis and the longitudinal axis of the second multi-link structure (3), which has the advantages of aesthetics, easy operation and low cost compared to other angles.

[0041] As shown in the drawings, Figure 2 , Figure 3 and Figure 5 , the middle connecting multi-link structure component (5) and the end connecting multi-link structure component (4) connect the first multi-link structure (2) and the second multi-link structure (3) at a predetermined interval, which has the effect of making the first multi-link structure (2) and the second multi-link structure (3) stretch in the same direction, which can achieve simultaneous adjustment of the size of multiple accommodation sample spaces, and also has the effect of clamping and fixing the sample, avoiding the mutual adhesion of the samples while fully soaking the sample, ensuring the effectiveness of the sample during detection, compared to the conventional manual soaking method, not only reduces the soaking time of the sample, but also improves the convenience of soaking and the overall detection efficiency.

[0042] As shown in the drawings, Figure 2 and Figure 4 , the first multi-link structure (2) and the second multi-link structure (3) each include a plurality of first and second connecting link structure groups (7) connected end to end, which can achieve batch processing of samples, when the preferred number of connecting link structure groups (7) is 5, it means that the sample clamping support can process 10 samples at the same time, which fully meets the requirements of the current national standard GB / T 465.1-2008 for the number of samples to be detected, ensuring the rigor of the detection, the connecting link structure group (7) is composed of a first connecting link (71) and a second connecting link (72) by hinging, which can reduce the manufacturing cost of the sample clamping support, the first connecting link (71) and the second connecting link (72) are both configured to a predetermined length, facilitating more effective clamping of the sample.

[0043] AsFigure 2 and Figure 5 As shown, the ends of the first link (71) and the second link (72) are both hinged to the ends of the component (4) of the end-connected multi-link structure, and the middle part of the link structure group (7) is hinged to the end of the component (5) of the middle-connected multi-link structure.

[0044] like Figures 1-5 As shown, the first multi-link structure (2), the second multi-link structure (3), the component (4) connecting the end of the multi-link structure, and the component (5) connecting the middle of the multi-link structure can be made of stainless steel rods with small outer diameters. This not only ensures that the sample holder has a certain structural strength, but also reduces manufacturing costs, makes it easy to use, and extends the service life of the sample holder.

[0045] The sample holder of this embodiment can process batches of samples simultaneously. The plane formed by the bottom multi-link structure supports the samples. In this case, the sample holder can be used as a support for each sample before soaking, facilitating sample preparation and subsequent transfer. During sample soaking, the space for accommodating the samples can be adjusted to hold and fix them in place. The plane formed by the top multi-link structure has a limiting function, preventing the samples from floating to the surface of the soaking solution due to buoyancy in the initial soaking stage. The plane formed by the bottom multi-link structure supports the samples, preventing them from floating to the surface of the soaking solution during soaking. Subsequently, due to gravity, the contact with the bottom of the container affects the soaking effect. However, the structural advantages of the sample clamping bracket, which is formed by the interconnection of the top multi-link structure, bottom multi-link structure, end multi-link structure, and middle multi-link structure, can better prevent the sample from becoming loose in other forms during soaking. This ensures that the sample and the sides and bottom of the container maintain a certain distance, guaranteeing the soaking effect. After the sample soaking is completed, it can also be used as a sample draining bracket to prevent the sample, which has become soft and fragile after being fully soaked, from being damaged or contaminated due to frequent transfer, thus greatly improving the sample processing efficiency.

[0046] The sample holder of the present disclosure is particularly suitable for immersion operations of plate-shaped or sheet-shaped samples, such as immersion operations of cardboard or paper samples, and has good applicability.

[0047] Some embodiments of this disclosure provide a water immersion bursting strength testing device, including the aforementioned sample clamping bracket, which is used to immerse cardboard or paper samples in water. The sample clamping bracket of this disclosure, applied in a water immersion bursting strength testing device, serves as a pretreatment device for placing cardboard or paper samples and performing immersion and draining operations, effectively improving testing efficiency and demonstrating high feasibility.
