Description

Technical Field

[0001] This utility model belongs to the field of textile testing technology, and specifically relates to a sample cutting device for textile testing. Background Technology

[0002] Quality testing is a key aspect of textile quality control. It includes physical properties (breaking strength, elastic recovery rate, fatigue performance, seam cracking, seam strength, yarn slippage, color fastness, bursting strength, etc.) and chemical properties (formaldehyde, azo dyes, heavy metals, phthalate content, pH value, etc.), all of which must meet the requirements of national standards.

[0003] There are two common methods for testing the physical properties of fabrics by cutting samples. One method is to draw the specified dimensions with a ruler and then cut by hand. This method is time-consuming, labor-intensive, and inefficient. The other method is to make templates of various sizes and cut by hand according to the template dimensions. This method does not fix the sample firmly enough and is prone to dimensional deviations.

[0004] Chemical performance testing often involves directly cutting fabric into pieces with scissors, resulting in inconsistent sizes. Devices capable of both physical and chemical testing are typically pneumatic cutters, which use pneumatic force to cut samples according to customized molds of various sizes. This method involves expensive instruments and molds, and some instruments leave sample residue after cutting, affecting testing efficiency during the cleaning process.

[0005] For example, the existing patent CN221173908U, a sample cutter for textile testing, is only applicable to cutting 5mm*5mm samples, which limits its scope of application.

[0006] For example, patent CN203981473U describes a textile testing sample cutting device, which is a pneumatic cutting device that can cut some physical performance test samples and some chemical performance test samples. However, the device is relatively complex and has a high cost (equipment purchase, maintenance, customization of different sized cutting dies, etc.). In addition, due to the limitation of the instrument's workbench size, it cannot cut larger samples.

[0007] Therefore, there is currently no simple device in textile testing that can efficiently cut samples for both physical and chemical performance testing, and is also inexpensive.

[0008] The above background information is provided only to assist in understanding the inventive concept and technical solution of this utility model. It does not necessarily belong to the prior art of this utility model. In the absence of clear evidence that the above information was disclosed before the application date of this utility model, the above background information should not be used to evaluate the novelty and inventiveness of this utility model. Utility Model Content

[0009] In view of this, in order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a cutting device for textile testing that can achieve manual and accurate cutting of samples at a low cost.

[0010] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] A sample cutting device for textile testing includes a pressure frame and a control plate, which are detachably connected. The pressure frame includes a rectangular frame formed by connecting multiple pressure plates end to end, used to delineate the cutting area and to hold the textile to be cut. The control plate is used to fix a position within the pressure frame to cut a sample of a set size.

[0012] Preferably, both the pressure frame and the control board are made of stainless steel, with the overall weight of the pressure frame being 3.5–5 kg and the overall weight of the control board being 0.3–1.0 kg.

[0013] According to some preferred embodiments of the present invention, when the control plate is fixed inside the pressure frame, the control plate is parallel to the pressure plate direction of the rectangular frame and is used to control the cutting direction of the sample.

[0014] According to some preferred embodiments of this utility model, the pressure plate includes two first pressure plates arranged along a first direction and two second pressure plates arranged along a second direction, with the two first pressure plates facing each other and the two second pressure plates facing each other. The four pressure plates are connected end to end to form a rectangular frame. Depending on the lengths of the first and second pressure plates, the rectangular frame can be rectangular (when the lengths of the first and second pressure plates are not equal) or square (when the lengths of the first and second pressure plates are equal).

[0015] According to some preferred embodiments of the present invention, the control plate includes a first control plate arranged parallel to the first pressure plate, the length of the first control plate being equal to the distance between the two second pressure plates; and / or, the control plate includes a second control plate arranged parallel to the second pressure plates, the length of the second control plate being equal to the distance between the two first pressure plates. When the rectangular frame is square, all control plates can be of equal length; when the rectangular frame is rectangular, the control plate includes a first control plate and a second control plate of unequal length to cooperate with the length and width directions of the rectangular frame, guiding the cutting direction of the sample.

[0016] According to some preferred embodiments of the present invention, the pressure frame includes baffles disposed on the inner side of the pressure plate, and a fixing groove for fixing the end of the control plate is formed between adjacent baffles. The baffles are used to limit the position of the control plate and prevent the control plate from moving during the sampling process.

[0017] According to some preferred embodiments of the present invention, the width of the fixing groove is matched with the width of the control plate to prevent the control plate from shaking or moving within the fixing groove.

[0018] According to some preferred embodiments of the present invention, the pressure frame includes an identification block with a scale, which allows for quick planning and identification of the cutting position and size of the sample.

[0019] According to some preferred embodiments of the present invention, the marking block is disposed on the outer side of the pressure plate, and the scale is disposed on the top surface of the pressure plate and / or the marking block.

[0020] According to some preferred embodiments of the present invention, the stop bar is formed by extending a portion of the scale line of the scale towards the inside of the pressure plate.

[0021] Preferably, the scale structure is the same as a regular ruler, with a graduation value of 1mm, 5mm as a small graduation, and 10mm as a large graduation. The measuring range is determined according to the length of the pressure plate and the marking block, and can be 20-80mm. Preferably, the graduation lines of the small graduations extend into the inside of the rectangular frame to form a stop bar. In this way, the stop bar corresponds to a specific graduation, which allows for faster planning and identification of the cutting position and size of the sample.

[0022] According to some preferred embodiments of this utility model, the height of the control plate is less than or equal to the height of the stop bar, to prevent the control plate from moving. When the height of the control plate is less than the height of the stop bar, the bottom surface of the stop bar is flush with the bottom surface of the pressure plate.

[0023] According to some preferred embodiments of this utility model, the height of the stop bar is less than or equal to the height of the pressure plate, to prevent movement of the control plate. Preferably, the height of the stop bar is equal to the height of the pressure plate.

[0024] According to some preferred embodiments of the present invention, the sample cutting device includes a worktable for supporting the pressing frame, the worktable being planar and having a size larger than that of the pressing frame.

[0025] Compared with the prior art, the advantages of this utility model are as follows: The sample cutting device for textile testing of this utility model uses a pressure frame to press the textile and a control plate to control the cutting direction and sample size. It can be used for cutting samples for some physical performance tests as well as some chemical performance tests, solving the problem of uneven sample size in textile testing, improving the accuracy of test results, and is low in cost, convenient, fast and efficient.

[0032] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0033] The sample cutting device for textile testing provided by this utility model can cut samples of different specifications and sizes, covering physical properties (breaking strength, elastic elongation recovery rate, fatigue performance, seam cracking, seam strength, yarn slippage, color fastness, bursting strength, etc.) and chemical properties (formaldehyde, azo dyes, heavy metals, phthalate content, pH value, etc.). The device is simple to use and easy to operate, avoiding the problem of results differences caused by inconsistent sample cutting sizes between laboratories. At the same time, it improves sample cutting efficiency and effectively controls costs and reduces subsequent maintenance costs.

[0034] Specifically, such as Figure 1-4As shown, the sample cutting device for textile testing of this utility model includes a pressure frame 1 and a control plate, which are detachably connected. The pressure frame 1 includes a rectangular frame formed by connecting multiple pressure plates end to end, a stop bar 4 disposed on the inner side of the pressure plates, and an identification block 6 disposed on the outer side of the pressure plates. The identification block 6 is provided with a scale 7, which allows for quick planning and identification of the cutting position and size of the sample. The pressure frame 1 is used to delineate the cutting area and to hold the textile to be cut. The control plate is used to fix the position within the pressure frame 1 to cut the sample to a set size. When the control plate is fixed within the pressure frame 1, the control plate is parallel to the pressure plate direction of the rectangular frame and is used to control the cutting direction of the sample.

[0035] The pressure plate includes two first pressure plates 21 arranged along a first direction and two second pressure plates 22 arranged along a second direction. The two first pressure plates 21 are arranged opposite each other, and the two second pressure plates 22 are arranged opposite each other. The four pressure plates are connected end to end to form a rectangular frame. Depending on the length of the first pressure plate 21 and the second pressure plate 22, the rectangular frame can be a rectangle (the lengths of the first pressure plate 21 and the second pressure plate 22 are not equal) or a square (the lengths of the first pressure plate 21 and the second pressure plate 22 are equal). When the rectangular frame is rectangular, the first direction is the length direction of the rectangular frame, and the second direction is the width direction of the rectangular frame, and the two are perpendicular to each other. The length of the first pressure plate 21 is greater than the length of the second pressure plate 22.

[0036] Correspondingly, the control plate includes a first control plate 31 arranged parallel to the first pressure plate 21, the length of which is equal to the distance between the two second pressure plates 22; and / or, the control plate includes a second control plate 32 arranged parallel to the second pressure plates 22, the length of which is equal to the distance between the two first pressure plates 21. When the rectangular frame is square, all control plates can be of equal length, i.e., the first control plate 31 and the second control plate 32 are the same; when the rectangular frame is rectangular, the control plate includes a first control plate 31 and a second control plate 32 of unequal length to match the length and width directions of the rectangular frame, guiding the cutting direction of the sample.

[0037] A fixing groove 5 is formed between adjacent retaining strips 4 to fix the end of the control board. The retaining strips 4 extend inward from the inner wall of the pressure plate by 0.5-2cm. The retaining strips 4 are used to limit the position of the control board and prevent the control board from moving during sampling. The width of the fixing groove 5 matches the width of the control board to prevent the control board from shaking or moving within the fixing groove 5.

[0038] The height of the control plate is less than or equal to the height of the stop bar 4 to prevent movement of the control plate. When the height of the control plate is less than the height of the stop bar 4, the bottom surface of the stop bar 4 is flush with the bottom surface of the pressure plate. The height of the stop bar 4 is less than or equal to the height of the pressure plate to prevent movement of the control plate. Preferably, the height of the stop bar 4 is equal to the height of the pressure plate. When the height of the control plate is large (≥1cm), the lower ends of both ends of the control plate are set with slopes, facing downwards and outwards. The fixing slots are correspondingly set with slopes, facing upwards and towards the inside of the frame, to facilitate the placement of the control plate into the fixing slots, prevent jamming, and automatically center when the control plate is placed into the fixing slots.

[0039] The scale 7 is set on the top surface of the pressure plate and / or the marking block 6. The stop bar 4 is formed by extending a portion of the scale line of the scale 7 towards the inside of the pressure plate. Preferably, the structure of the scale 7 is the same as that of a regular ruler, with a graduation value of 1 mm, 5 mm as a small scale 7, and 10 mm as a large scale 7. The measuring range is determined according to the length of the pressure plate and the marking block 6, and can be 20-80 mm. Preferably, the stop bar 4 is formed by extending the scale line of the small scale 7 towards the inside of the rectangular frame, that is, the width of the fixing groove 5 and the width of the control plate are 5 mm. In this way, the stop bar 4 corresponds to a specific scale 7, which enables faster planning and identification of the cutting position and size of the sample.

[0040] Preferably, both the pressure frame 1 and the control board are made of stainless steel, with the overall weight of the pressure frame 1 being 3.5 to 5 kg and the overall weight of the control board being 0.3 to 1.0 kg.

[0041] The cutting device includes a worktable for supporting the pressing frame 1. The worktable is planar and its size is larger than that of the pressing frame 1. Preferably, the surface of the worktable is made of PVC material with self-healing cut marks and non-slip properties, which works in conjunction with the pressing frame to fix the textile.

[0042] The method for cutting textile test samples using the cutting device with the above structure includes the following steps:

[0043] After laying the textile flat on the workbench, place the pressure frame 1 on the textile; the size of the textile is larger than the size of the pressure frame 1.

[0044] Fix the control plate to the pressure frame 1 and cut the sample in one direction (one of the first and second directions);

[0045] Adjust the control plate and fix it on the pressure frame 1 again, and cut the sample in another direction (the remaining direction between the first and second directions) to remove the sample from the textile and obtain the sample for textile testing.

[0046] When the rectangular frame is rectangular, control plates of different lengths are needed for the two directions of cutting the sample; when the rectangular frame is square, the lengths of the control plates are the same, and the direction of the control plates can be adjusted.

[0047] Example 1

[0048] like Figure 1-4 As shown, the sample cutting device for textile testing in this embodiment includes a workbench, a pressure frame 1, and a control plate, with a detachable connection between the pressure frame 1 and the control plate. The pressure frame 1 includes a rectangular frame formed by connecting multiple pressure plates end-to-end, a stop bar 4 disposed on the inner side of the pressure plates, and an identification block 6 disposed on the outer side of the pressure plates. The identification block 6 is provided with a scale 7, which allows for quick planning and identification of the cutting position and size of the sample. The pressure frame 1 is used to delineate the cutting area and to hold the textile to be cut. The control plate is used to fix the position within the pressure frame 1 to cut the sample of a set size. When the control plate is fixed within the pressure frame 1, it is parallel to the pressure plate direction of the rectangular frame and is used to control the cutting direction of the sample. The workbench is used to support the pressure frame 1 and the control plate during cutting. The workbench is planar and its size is larger than that of the pressure frame 1. The surface of the workbench is made of PVC material with good self-healing cut marks and low slippage (high friction), which works in conjunction with the pressure frame to fix the textile.

[0049] The pressure plate includes two first pressure plates 21 arranged along a first direction and two second pressure plates 22 arranged along a second direction. The two first pressure plates 21 are arranged opposite each other, and the two second pressure plates 22 are arranged opposite each other. The four pressure plates are connected end to end to form a rectangular frame. Depending on the length of the first pressure plate 21 and the length of the second pressure plate 22, the rectangular frame can be a rectangle (when the lengths of the first pressure plate 21 and the second pressure plate 22 are not equal) or a square (when the lengths of the first pressure plate 21 and the second pressure plate 22 are equal). In this embodiment, the rectangular frame is rectangular, the first direction is the length direction of the rectangular frame, and the second direction is the width direction of the rectangular frame, which are perpendicular to each other. The length of the first pressure plate 21 is greater than the length of the second pressure plate 22.

[0050] Correspondingly, the control plate includes a first control plate 31 arranged parallel to the first pressure plate 21 and a second control plate 32 arranged parallel to the second pressure plate 22. The length of the first control plate 31 is equal to the distance between the two second pressure plates 22; the length of the second control plate 32 is equal to the distance between the two first pressure plates 21. When the rectangular frame is rectangular, the control plate includes first control plates 31 and second control plates 32 of unequal lengths to match the length and width directions of the rectangular frame and guide the cutting direction of the sample. One frame is equipped with at least four first control plates 31 and four second control plates 32.

[0051] A fixing groove 5 is formed between adjacent retaining strips 4 to fix the end of the control board. The retaining strips 4 extend inward from the inner wall of the pressure plate by 0.5-2cm. The retaining strips 4 are used to limit the position of the control board and prevent the control board from moving during sampling. The width of the fixing groove 5 matches the width of the control board to prevent the control board from shaking or moving within the fixing groove 5.

[0052] The height of the control plate is less than or equal to the height of the stop bar 4 to prevent movement of the control plate. When the height of the control plate is less than the height of the stop bar 4, the bottom surface of the stop bar 4 is flush with the bottom surface of the pressure plate. The height of the stop bar 4 is less than or equal to the height of the pressure plate to prevent movement of the control plate. Preferably, the height of the stop bar 4 is equal to the height of the pressure plate. In some embodiments, when the height of the control plate is large (≥1cm), the lower ends of both ends of the control plate are sloped, with the slopes facing downwards and outwards. The fixing groove is correspondingly provided with a slope, with the slope facing upwards and towards the inside of the frame, to facilitate the placement of the control plate into the fixing groove, prevent jamming, and automatically center when the control plate is placed into the fixing groove, and keep the bottom surface of the control plate horizontal to fit the textile to be cut.

[0053] Scale 7 is set on the top surface of the pressure plate and the marker block 6. The stop bar 4 is formed by extending part of the scale line of scale 7 into the inside of the pressure plate. The marker block 6 is located in the middle of each side, ensuring that the scale lines on opposite sides are completely aligned. At the same time, the marker blocks 6 on the four sides can also be used as handles to facilitate lifting and lowering the device.

[0054] In this embodiment, the rectangular frame has a length of 50cm, a width of 30cm, a pressure plate height of 5cm, and a marking block 6 thickness of 2cm. The first control plate 31 controls the length dimension, with a width of 5mm, a height of 10mm, and a length of 50cm, and is used to securely fit into the fixing grooves 5 on the two long opposite sides of the rectangular frame. The second control plate 32 controls the width dimension, with a width of 5mm, a height of 10mm, and a length of 30mm, and is used to securely fit into the fixing grooves 5 on the two short opposite sides of the rectangular frame.

[0055] The structure of scale 7 is the same as that of a regular ruler, with a graduation value of 1mm. Starting from 0mm, each small scale 7 is 5mm, and each large scale 7 is 10mm. The measuring range is determined by the length of the pressure plate and the marking block 6, and can be 20-80mm. In this embodiment, the measuring range of scale 7 corresponding to the first pressure plate 21 is 40mm, and the measuring range of scale 7 corresponding to the second pressure plate 22 is 20mm. Preferably, the scale line of the small scale 7 extends inward to form a stop bar 4. In this way, the stop bar 4 corresponds to a specific scale 7, which enables faster planning and identification of the cutting position and size of the sample. In this embodiment, edge baffles 41 are also provided on both sides of the marking block 6. One edge baffle 41 extends forward 5mm from the 0mm scale 7 and then extends inward to the inside of the rectangular frame. The other edge baffle 41 extends backward 5mm from the scale 7 with the maximum measuring range and then extends inward to the inside of the rectangular frame. By setting the edge baffle 41, the cutting area can be expanded to maximize the use of the scale 7 range.

[0056] Both the pressure frame 1 and the control board are made of stainless steel. The overall weight of the pressure frame 1 is 4Kg; the overall weight of the first control board is 0.5Kg; and the overall weight of the second control board is 0.3Kg.

[0057] Example 2

[0058] The method for cutting textile test samples using the cutting device described in Example 1 above includes the following steps:

[0059] Step S1: Laying textiles

[0060] After laying the textile flat on the workbench, place the pressure frame 1 on the textile; the size of the textile is larger than the size of the pressure frame 1.

[0061] Step S2, First Cut

[0062] Based on the set sample size, the first control plate 31 is fixed to the pressure frame 1 by the baffle and fixing groove 5 at the appropriate position, and the sample is cut in the first direction (horizontal direction).

[0063] Step S3, Second Cut

[0064] According to the set sample size, remove the first control plate 31, replace it with the second control plate 32, and fix it to the pressure frame 1 again through the baffle and fixing groove 5 in a suitable position. Use a cutting knife with a suitable blade thickness to cut the sample in the second direction (vertical direction).

[0065] After two cuts, the sample is removed from the textile to obtain a sample for textile testing.

[0066] During the cutting process, the control plate needs to be pressed down by hand to ensure it adheres firmly to the textile, preventing dimensional deviations due to insecure fixing. Furthermore, when multiple samples need to be cut simultaneously, multiple first control plates 31 or second control plates 32 can be used for simultaneous cutting. Afterward, the control plate can be replaced, and the cutting direction changed again, to obtain multiple samples at the same time.

[0067] The steps S2 and S3 above can also be interchanged, that is, the sample is cut in the second direction (vertical direction) first, and then the sample is cut in the first direction (horizontal direction).

[0068] This invention relates to a sample cutting device for textile testing. A pressure frame 1 holds the textile in place on the operating table, preventing dimensional deviations during cutting due to insecure fabric fixation. After the textile is secured, a fabric cutter is used to cut it. A control panel controls the cutting direction and sample size. This device can be used for cutting samples for some physical and chemical performance tests, solving the problem of uneven sample size in textile testing, improving the accuracy of test results, and offering low cost, convenience, speed, and high efficiency.

[0069] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model.
