Description

Technical Field

[0001] This application belongs to the field of testing equipment technology, and in particular relates to an indentation stiffness testing device. Background Technology

[0002] Packaging boxes are products formed by folding packaging paper with corresponding shapes and creases. Packaging paper with adequate crease stiffness (strength) is less likely to cause paper jams when it is formed by the packaging machine. However, when the crease stiffness of the packaging paper is not up to standard, it is easy to cause problems such as paper jams and machine stoppages, and poor packaging box formation. The crease stiffness of the packaging paper is closely related to the quality of the packaging box.

[0003] Therefore, in the production of packaging boxes, existing technologies require cutting samples of the crease area of ​​a certain type and category of packaging paper and testing the crease stiffness. The crease stiffness testing process in related technologies requires manual operation by operators, which is cumbersome, time-consuming, and inefficient, and urgently needs to be improved. Utility Model Content

[0004] This application provides an indentation stiffness testing device that simplifies the indentation stiffness testing steps, reduces the indentation stiffness testing time, and improves the efficiency of indentation stiffness testing.

[0005] This application discloses an indentation stiffness testing device, comprising a sampling mechanism including a mounting part, a loading part, and a cutting part. The mounting part and the loading part are spaced apart in a first direction to form a chamber for containing material. The loading part has a sampling port extending through it. The cutting part is movably disposed on the mounting part along the first direction, and its orthogonal projection in the first direction is located within the sampling port. A conveying mechanism, at least a portion of which is disposed on the side of the loading part away from the mounting part, is positioned with the sampling port facing the conveying mechanism. A first negative pressure mechanism is disposed on the side of the conveying mechanism away from the sampling port and facing the sampling port. A detection mechanism is spaced apart from the sampling mechanism and facing the conveying mechanism. The detection mechanism is used to acquire indentation information of the sample. A control mechanism is electrically connected to the detection mechanism and is used to determine whether the indentation stiffness of the sample is qualified based on the indentation information of the sample.

[0006] The indentation stiffness testing device of this application includes a sampling mechanism, a conveying mechanism, a first negative pressure mechanism, and a testing mechanism. The sampling mechanism includes a mounting part, a loading part, and a cutting component. The mounting part and the loading part are spaced apart in a first direction to form a chamber. The loading part has a sampling port through it. The cutting component is movably disposed on the mounting part along the first direction. When material is placed in the chamber, the cutting component automatically cuts the material to form a sample. At least part of the conveying mechanism is disposed on the side of the loading part away from the mounting part, and the sampling port is disposed facing the conveying mechanism so that the sample can fall into the conveying mechanism through the sampling port, so that the conveying mechanism can automatically transport the sample to the next process. The first negative pressure mechanism is disposed on the conveying mechanism away from the sampling port. The sampling mechanism is positioned on one side and faces the sampling port. The negative pressure generated by the first negative pressure mechanism attracts the sample, causing it to fall smoothly onto the conveying mechanism after passing through the sampling port. The detection mechanism and the sampling mechanism are spaced apart. The conveying mechanism automatically transports the sample to the detection mechanism, which faces the conveying mechanism so that it can obtain the indentation information of the sample. The control mechanism is electrically connected to the detection mechanism and can determine whether the indentation stiffness is qualified based on the indentation information of the sample. By using the indentation stiffness testing equipment of this application embodiment, the indentation stiffness testing process of the sample can be automatically realized, which helps to simplify the indentation stiffness testing steps, reduce the indentation stiffness testing time, and improve the efficiency of indentation stiffness testing.

[0007] In some possible implementations, the conveying mechanism includes a conveyor belt and at least two drive units spaced apart along a second direction. The conveyor belt is wound around the drive units and extends between the sampling mechanism and the detection mechanism. The conveyor belt is movably arranged in the second direction, where the first direction and the second direction intersect. A suction hole is provided through the conveyor belt, and a first negative pressure mechanism is used to attract the sample in the sampling port through the suction hole.

[0008] In some possible implementations, the conveyor belt includes a first half and a second half disposed opposite each other along a first direction, and a first negative pressure mechanism is disposed between the first half and the second half.

[0009] In some feasible implementations, the conveyor belt includes two sub-conveyor belts spaced apart along a third direction to form suction holes, with the first direction, second direction, and third direction intersecting each other.

[0010] In some feasible ways, the sampling port's orthographic projection onto the conveyor belt coincides with at least a partial suction hole.

To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0038] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the indentation stiffness testing device according to an embodiment of this application; Figure 2 for Figure 1 Sectional view at point AA.

[0039] This application provides an indentation stiffness testing device 1, such as... Figure 1 and Figure 2As shown, the indentation stiffness testing device 1 includes a sampling mechanism 10, a conveying mechanism 20, a first negative pressure mechanism 30, and a testing mechanism 40. The sampling mechanism 10 includes a mounting part 11, a loading part 12, and a cutting part 13. The mounting part 11 and the loading part 12 are spaced apart in the first direction X to form a chamber 14 for containing materials. The loading part 12 is provided with a sampling port 121. The cutting part 13 is movably disposed on the mounting part 11 along the first direction X, and its orthogonal projection in the first direction X is located within the sampling port 121. At least part of the conveyor... The sampling mechanism 20 is located on the side of the carrying part 12 away from the mounting part 11, and the sampling port 121 is positioned towards the conveying mechanism 20; the first negative pressure mechanism 30 is located on the side of the conveying mechanism 20 away from the sampling port 121 and is positioned towards the sampling port 121; the detection mechanism 40 is spaced apart from the sampling mechanism 10 and is positioned towards the conveying mechanism 20, and the detection mechanism 40 is used to acquire the indentation information of the sample; the control mechanism 50 is electrically connected to the detection mechanism 40, and the control mechanism 50 is used to determine whether the indentation stiffness of the sample is qualified based on the indentation information of the sample.

[0040] In related technologies, the indentation stiffness test of materials needs to be completed manually by the operator. The operator needs to first take a sample of the material and then take the sample to the stiffness tester for inspection. The test process is time-consuming and the reliability of manual operation is poor, resulting in low test efficiency.

[0041] In the indentation stiffness testing device 1 provided in this application embodiment, the indentation stiffness testing device 1 includes a sampling mechanism 10, a conveying mechanism 20, a first negative pressure mechanism 30, and a detection mechanism 40. The sampling mechanism 10 includes a mounting part 11, a loading part 12, and a cutting part 13. The mounting part 11 and the loading part 12 are spaced apart in the first direction X to form a chamber 14. The loading part 12 is provided with a sampling port 121. The cutting part 13 is movably disposed on the mounting part 11 along the first direction X. When the material is placed in the chamber 14, the cutting part 13 automatically cuts the material to form a sample. At least part of the conveying mechanism 20 is disposed on the side of the loading part 12 away from the mounting part 11. The sampling port 121 is disposed facing the conveying mechanism 20 so that the sample can fall into the conveying mechanism 20 through the sampling port 121, so that the conveying mechanism 20 can automatically transport the sample to the next process. A negative pressure mechanism 30 is disposed on the side of the conveying mechanism 20 away from the sampling port 121 and facing the sampling port 121. The negative pressure generated by the first negative pressure mechanism 30 attracts the sample, so that the sample falls smoothly onto the conveying mechanism 20 after passing through the sampling port 121. The detection mechanism 40 and the sampling mechanism 10 are disposed at intervals. The conveying mechanism 20 automatically transports the sample to the detection mechanism 40. The detection mechanism 40 faces the conveying mechanism 20 so that the detection mechanism 40 can obtain the indentation information of the sample. The control mechanism 50 is electrically connected to the detection mechanism 40. The control mechanism 50 can determine whether the indentation stiffness is qualified based on the indentation information of the sample. By adopting the indentation stiffness testing device 1 of this application embodiment, the indentation stiffness testing process of the sample can be automatically realized, which helps to simplify the indentation stiffness testing steps, reduce the indentation stiffness testing time, and improve the indentation stiffness testing efficiency.

[0042] Specifically, the sampling mechanism 10 includes a loading section 12 and a mounting section 11. The mounting section 11 is used to mount the cutting piece 13, and the loading section 12 is flat to facilitate the carrying of materials.

[0043] The material refers to the paper that needs to be cut and sampled, and the sample refers to the part of the material that is cut and peeled off by the cutter 13. For example, the material can be cigarette pack paper, white cardboard, packaging paper, etc.

[0044] The sampling mechanism 10 also includes a chamber 14 formed by a spaced-apart loading section 12 and a mounting section 11, the chamber 14 having one or more openings through which material can enter the chamber 14.

[0045] Optionally, the shape, number, and area of ​​the openings can be designed according to the material size requirements.

[0046] Optionally, the two openings are arranged opposite each other along the third direction Z, and the material can enter the chamber 14 through one opening and extend out through the other opening, so that the sampling mechanism 10 can adapt to the sampling needs of materials of a longer size.

[0047] Optionally, the sampling mechanism 10 may also include a support part 41, which is connected between the loading part 12 and the mounting part 11 to improve the structural strength of the sampling mechanism 10 and reduce the difficulty of fixing the sampling mechanism 10; or the sampling mechanism 10 and the mounting part 11 are independent of each other and are respectively connected to their respective mounting positions, with the openings surrounding the chamber 14, so that the material can enter the chamber 14 from more angles.

[0048] The loading section 12 is flat, and a sampling port 121 is provided through the loading section 12. The shape and size of the sampling port 121 can be designed by the user. For example, the sampling port 121 is circular, rectangular, or hexagonal. For example, the sampling port 121 is rectangular with a size of 36mm*38mm.

[0049] The orthographic projection of the cut piece 13 in the first direction X is located inside the sampling port 121. The cutting area of ​​the cut piece 13 is smaller than the area of ​​the sampling port 121. Therefore, the area of ​​the sample after the cut piece 13 is cut is smaller than the area of ​​the sampling port 121, so that the cut sample can be smoothly removed from the sampling port 121.

[0050] Optionally, the shape of the cutter 13 matches the shape of the sampling port 121, and the edges of the cutter 13 and the sampling port 121 work together to cut the sample, thereby improving cutting reliability and reducing the risk of material tearing. For example, the cutter 13 is circular, rectangular, or hexagonal, etc.

[0051] Optionally, the cutting part 13 and the mounting part 11 are connected by a hydraulic cylinder, a pneumatic cylinder, a motor, etc., so that the cutting part 13 can be reciprocated relative to the mounting part 11 in the first direction X.

[0052] Optionally, the mounting section 11 is also provided with an aperture that emits light toward the edge of the sampling port 121, so as to indicate the position of the sampling port 121 on the material when the material blocks the sampling port 121, thereby reducing the difficulty of operating the sampling mechanism 10. For example, the aperture is provided around the cutting member 13 and is provided toward the carrying section 12 along the first direction X, so as to reduce the difficulty of setting the aperture.

[0053] Optionally, the conveying mechanism 20 can be a conveyor belt assembly, a robotic arm, or an AGV (Automated Guided Vehicle), etc. The sampling port 121 is set facing the conveying mechanism 20 so that after the material is cut by the cutting piece 13, the sample can fall onto the conveying mechanism 20 through the sampling port 121 and be conveyed by the conveying mechanism 20 to the testing mechanism 40. The program design involved in the conveying process of the conveying mechanism 20 can be implemented by relevant technical personnel based on existing technology, or by combining existing technology, and is not limited here.

[0054] Optionally, if the sampling port 121 is set towards the conveying mechanism 20, then the orthographic projection of the sampling port 121 in the first direction X is located inside the conveying mechanism 20. If the sampling port 121 is set towards the inside of the conveying mechanism 20, then after the sample comes out of the sampling port 121, it can fall more stably into the conveying mechanism 20 along the first direction X, reducing the risk of the sample falling out of the conveying mechanism 20.

[0055] Optionally, the conveying mechanism 20 can be connected to the sampling mechanism 10 to keep them relatively fixed; or the conveying mechanism 20 and the sampling mechanism 10 can be independent of each other to facilitate adjustment of their positions.

[0056] Considering that after the material is cut by the cutting part 13, the sample may not be able to fall smoothly from the sampling port 121 due to friction, static electricity or other reasons, a first negative pressure mechanism 30 is provided in this embodiment of the application. The first negative pressure mechanism 30 is set towards the sampling port 121. The sampling port 121, the conveying mechanism 20 and the first negative pressure mechanism 30 are arranged in sequence along the first direction X, so as to cause the sample that does not fall smoothly in the sampling port 121 to be subjected to negative pressure suction and fall onto the conveying mechanism 20.

[0057] It should be clarified that relevant technical personnel can adjust the power of the first negative pressure mechanism 30 according to the actual situation to avoid the sample being excessively attracted into the first negative pressure mechanism 30.

[0058] Optionally, the first negative pressure mechanism 30 and the cutting piece 13 are linked. When the cutting piece 13 moves along the first direction X, the first negative pressure mechanism 30 applies a suction force to the sampling port 121 to reduce the energy consumption of the indentation stiffness testing device 1; or when the indentation stiffness testing device 1 is running, the first negative pressure mechanism 30 continuously applies a suction force to the sampling port 121 to reduce the control difficulty of the indentation stiffness testing device 1.

[0059] The testing mechanism 40 is positioned toward the conveying mechanism 20 to form a testing area. After the conveying mechanism 20 conveys the sample into the testing area, the testing mechanism 40 acquires the surface information of the sample to be tested, including the indentation depth information.

[0060] For example, the testing organization 40 may include a laser rangefinder, a laser scanner, a microwave rangefinder, etc.

[0061] The control mechanism 50 and the detection mechanism 40 are electrically connected. The control mechanism 50 compares the indentation depth information obtained by the detection mechanism 40 with the preset indentation depth information to determine whether the indentation depth of the sample is qualified, thereby determining whether the indentation stiffness of the sample is qualified.

[0062] It should be clarified that the specific program design for the indentation depth information obtained by the testing agency 40, and the specific program design for the control agency 50 for judging whether the sample indentation stiffness is qualified based on the indentation depth information obtained by the testing agency 40, can be implemented by relevant technical personnel using existing technologies or by combining existing technologies, without any restrictions.

[0063] For example, if the sample indentation depth is greater than the preset indentation depth range, the sample indentation stiffness is judged to be too low; if the sample indentation depth is less than the preset indentation depth range, the sample indentation stiffness is judged to be too high; if the sample indentation depth is within the preset indentation depth range, the sample indentation stiffness is judged to be qualified.

[0064] For example, the sample indentation depth can be represented by the distance between the point in the indentation and the detection mechanism 40; or it can be represented by the difference between the distance between the point in the non-indentation area of ​​the sample and the detection mechanism 40, and the distance between the point in the indentation area and the detection mechanism 40.

[0065] Optionally, the control mechanism 50 includes a display screen, on which sample information exceeding the preset indentation depth information will be marked. The program design involved in the above process can be implemented by relevant technical personnel based on existing technology, or by combining existing technology, and is not limited here.

[0066] Please see Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the structure of an indentation stiffness testing device according to another embodiment of this application; Figure 4 for Figure 3 Sectional view at point BB.

[0067] In some feasible ways, such as Figure 3 and Figure 4 As shown, the conveying mechanism 20 includes a conveyor belt 21 and at least two drive units 22 spaced apart along the second direction Y. The conveyor belt 21 is wound around the drive units 22 and extends between the sampling mechanism 10 and the detection mechanism 40. The conveyor belt 21 is movably arranged in the second direction Y. The first direction X and the second direction Y intersect. A suction hole 211 is provided through the conveyor belt 21. The first negative pressure mechanism 30 is used to attract the sample in the sampling port 121 through the suction hole 211.

[0068] The conveying mechanism 20 includes at least two drive units 22 spaced apart along the second direction Y, and a conveyor belt 21 wound around each drive unit 22. The drive units 22 drive the conveyor belt 21 to move along the second direction Y. The conveyor belt 21 extends between the sampling mechanism 10 and the detection mechanism 40. The sample falls onto the conveyor belt 21 from the sampling port 121 and is conveyed to the detection mechanism 40 by the conveyor belt 21. The conveyor belt 21 can continuously convey the sample between the sampling mechanism 10 and the detection mechanism 40, which helps to improve the detection efficiency of the indentation stiffness testing device 1. A suction hole 211 is provided through the conveyor belt 21 to facilitate the first negative pressure mechanism 30 to attract the sample in the sampling port 121 through the suction hole 211, which helps to reduce the power of the first negative pressure mechanism 30 and reduce the overall energy consumption of the indentation stiffness testing device 1.

[0069] Optionally, the shape, size, number, and spacing of the suction holes 211 can be designed according to actual conditions. For example, the suction holes 211 can be circular, rectangular, or rhomboid, etc.

[0070] Optionally, multiple suction holes 211 are spaced apart on the conveyor belt 21 to improve the conveying efficiency of the conveying mechanism 20. Optionally, multiple suction holes 211 are equally spaced to ensure uniform force distribution at each suction hole 211 and reduce the risk of tearing of the conveyor belt 21.

[0071] Optionally, the conveyor belt 21 includes a first half 212 and a second half 213 arranged opposite to each other along the first direction X. The first half 212 and the second half 213 are disposed between the sampling port 121 and the first negative pressure mechanism 30 to reduce the difficulty of setting up the first negative pressure mechanism 30. For example, by adjusting the conveying speed of the conveyor belt 21 and the cutting speed of the cutting piece 13, the suction hole 211 of the first half 212, the suction hole 211 of the second half 213, and the sampling port 121 are connected in the first direction X when the cutting piece 13 is being cut.

[0072] In some feasible ways, such as Figure 3 and Figure 4 As shown, the conveyor belt 21 includes a first half 212 and a second half 213 arranged opposite to each other along the first direction X, and a first negative pressure mechanism 30 is disposed between the first half 212 and the second half 213.

[0073] The first negative pressure mechanism 30 is disposed between the first half 212 and the second half 213. The first negative pressure mechanism 30 and the sampling port 121 are separated only by the first half 212. The first negative pressure mechanism 30 can attract the sample from the sampling port 121 through the suction hole 211 of the first half 212, reducing the overall control difficulty of the indentation stiffness testing device 1.

[0074] Optionally, the first negative pressure mechanism 30 is disposed within the conveying mechanism 20, which helps to improve the compactness of the indentation stiffness testing equipment 1.

[0075] Please see Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of the structure of an indentation stiffness testing device according to another embodiment of this application; Figure 6 for Figure 5 Sectional view at point CC.

[0076] In some feasible ways, such as Figure 5 and Figure 6 As shown, the conveyor belt 21 includes two sub-conveyor belts 214, which are spaced apart along the third direction Z to form suction holes 211. The first direction X, the second direction Y and the third direction Z intersect each other.

[0077] Two sub-conveyor belts 214 are spaced apart along the third direction Z to form suction holes 211, reducing the difficulty of preparing suction holes 211, and the first negative pressure mechanism 30 can form a stable attraction force on the sampling port 121 through the suction holes 211.

[0078] The size and specifications of the two sub-conveyor belts 214 can be set by the user. For example, the two sub-conveyor belts 214 can be of the same specification, which helps to ensure that the two sub-conveyor belts 214 are subjected to uniform force.

[0079] Two sub-conveyor belts 214 are spaced apart along the third direction Z to form continuously extending suction holes 211. The width of the suction holes 211 can be designed by the user. For example, the width of the suction holes 211 is 2cm, 5cm, 7cm, etc.

[0080] Optionally, the two sub-conveyor belts 214 can be driven by the same drive unit 22, which helps the two sub-conveyor belts 214 to move synchronously; or the drive units 22 of the two sub-conveyor belts 214 can be independent of each other, so that the conveyor mechanism 20 can be easily repaired and replaced when one of the two sub-conveyor belts 214 is damaged.

[0081] Optionally, the suction hole 211 extends along a straight path, which helps to reduce the size of the suction hole 211, increase the area of ​​the sub-conveyor belt 214, and improve the structural strength of the sub-conveyor belt 214; or the suction hole 211 extends along a bent path, which helps to increase the size of the suction hole 211 to reduce the power requirements of the first negative pressure mechanism 30.

[0082] In some feasible ways, such as Figure 5 and Figure 6 As shown, the orthographic projection of the sampling port 121 onto the conveyor belt 21 coincides with at least a portion of the suction hole 211.

[0083] The sampling port 121 is projected onto the conveyor belt 21 and at least partially coincides with the suction hole 211, reducing the distance between the suction hole 211 and the sampling port 121, which helps the first negative pressure mechanism 30 to attract the sample from the sampling port 121.

[0084] The suction force generated by the first negative pressure mechanism 30 needs to act on the sampling port 121 through the suction hole 211. Therefore, the magnitude of the suction force on the sampling port 121 is affected by the distance between the first negative pressure mechanism 30 and the suction hole 211, as well as the distance between the suction hole 211 and the sampling port 121. When the orthographic projection of the sampling port 121 on the conveyor belt 21 coincides with at least part of the suction hole 211, the distance between the sampling port 121 and the suction hole 211 is minimized. By reducing the distance between the sampling port 121 and the suction hole 211, the suction force generated by the first negative pressure mechanism 30 can act more effectively on the sampling port, and the first negative pressure mechanism 30 can more effectively attract the sample from the sampling port 121.

[0085] Optionally, the distance from the suction hole 211 to the two sides of the sampling port 121 is the same in the width direction of the conveyor belt 21, so that the first negative pressure mechanism 30 applies a suction force to the middle area of ​​the sampling port 121, thereby improving the problem of uneven force on the sample and causing it to deflect and flip.

[0086] Please see Figure 7 and Figure 8 , Figure 7 This is a schematic diagram of the structure of an indentation stiffness testing device according to another embodiment of this application; Figure 8 for Figure 7 Sectional view at point DD.

[0087] In some feasible ways, such as Figure 7 and Figure 8 As shown, a fixed groove 215 is provided on the outer surface of the conveyor belt 21. The groove opening area S1 of the fixed groove 215 and the area S2 of the sampling port 121 satisfy S1≥S2. The fixed groove 215 is used to accommodate the sample.

[0088] The surface of the conveyor belt 21 is provided with fixing grooves 215 to fix the sample, which helps the sample to be stably held on the conveyor belt 21 during the transport of the sample by the conveyor mechanism 20.

[0089] The fixing groove 215 includes a groove bottom and a groove opening that are arranged opposite to each other. The groove bottom refers to the bottom of the fixing groove 215, and the groove opening refers to the opening of the fixing groove 215.

[0090] The area of ​​the fixed groove 215 is greater than or equal to the area of ​​the sampling port 121, so that when the fixed groove 215 and the sampling port 121 are aligned, the sample can fall from the sampling port 121 into the fixed groove 215. When the fixed groove 215 and the sampling port 121 are aligned, it means that as the conveyor belt 21 moves, the orthographic projection of the sampling port 121 on the conveyor belt 21 is located within the fixed groove 215.

[0091] Optionally, the shape of the fixing groove 215 matches the shape of the sampling port 121 to facilitate the fixing groove 215 in fixing the sample.

[0092] Optionally, multiple fixed grooves 215 are spaced apart on the conveyor belt 21 to improve the testing efficiency of the indentation stiffness testing device 1.

[0093] Optionally, the depth of the fixing groove 215 can be designed by the user.

[0094] In some feasible ways, such as Figure 7 and Figure 8 As shown, the suction hole 211 is provided through the bottom of the fixing groove 215.

[0095] The suction hole 211 is provided through the bottom of the fixing groove 215, which helps the first negative pressure mechanism 30 to fix the sample in the fixing groove 215.

[0096] Optionally, the suction hole 211 is centered at the bottom of the fixing groove 215 so that the sample is subjected to uniform force within the fixing groove 215.

[0097] Please see Figure 9 and Figure 10 , Figure 9 This is a schematic diagram of the structure of an indentation stiffness testing device according to another embodiment of this application; Figure 10 for Figure 9 Sectional view at EE.

[0098] In some feasible ways, such as Figure 9 and Figure 10 As shown, the indentation stiffness testing device 1 also includes a second negative pressure mechanism 60. The second negative pressure mechanism 60 and the conveying mechanism 20 are arranged at intervals along the second direction Y and are located on the side of the testing mechanism 40 away from the sampling mechanism 10 in the second direction Y. The second negative pressure mechanism 60 is arranged toward the end of the conveyor belt 21 away from the sampling mechanism 10 in the second direction Y.

[0099] The second negative pressure mechanism 60 is set toward the end of the conveyor belt 21 away from the sampling mechanism 10 along the second direction Y. The second negative pressure mechanism 60 is used to peel the sample that has been detected by the detection mechanism 40 and has reached the end of the conveyor belt 21 from the fixed groove 215, so as to facilitate the continuous transport of the sample by the conveyor belt 21 and improve the detection efficiency of the detection mechanism 40.

[0100] It should be made clear that relevant technical personnel can adjust the power and angle of the second negative pressure mechanism 60 themselves so that the sample can be peeled off from the fixing groove 215 without being sucked into the second negative pressure mechanism 60.

[0101] For example, the second negative pressure mechanism 60 is disposed along the second direction Y toward the end of the conveyor belt 21, shortening the distance between the second negative pressure mechanism 60 and the conveyor belt 21, so as to facilitate the second negative pressure mechanism 60 to peel off the sample in the fixing groove 215.

[0102] Optionally, a receiving element is provided between the second negative pressure mechanism 60 and the conveyor belt 21 to receive the sample detached from the fixing groove 215.

[0103] Optionally, the second negative pressure mechanism 60 and the conveying mechanism 20 are independent of each other to facilitate adjustment of the position of the second negative pressure mechanism 60; or the second negative pressure mechanism 60 and the conveying mechanism 20 are connected by a connecting frame to improve the compactness of the detection mechanism 40.

[0104] Please see Figure 11 , Figure 11 This is a schematic diagram of the structure of an indentation stiffness testing device according to another embodiment of this application.

[0105] In some feasible ways, such as Figure 11 As shown, multiple detection units 40 are distributed at intervals along the second direction Y.

[0106] If multiple testing institutions 40 are distributed at intervals along the second direction Y, the same sample will be tested by multiple testing institutions 40 during the conveyor belt 21, thereby improving the reliability of the test results.

[0107] Optionally, the number of detection units 40 and the spacing between adjacent detection units 40 can be designed independently. For example, 3, 5, or 7 detection units 40 are arranged at intervals along the sample transport direction.

[0108] Optionally, the testing mechanism 40 is fixedly connected to the installation position to reduce the impact of the shaking of the testing mechanism 40 on the testing results.

[0109] It should be clarified that the specific program design for the control mechanism 50 to process the indentation depth information obtained by multiple testing mechanisms 40 to determine whether the sample indentation stiffness is qualified can be implemented by relevant technical personnel using existing technologies or by combining existing technologies, without any restrictions.

[0110] In some feasible ways, such as Figure 11 As shown, the conveying mechanism 20 also includes a connecting part 23 extending in the second direction Y. The detection mechanism 40 includes a scanning part 42 and a support part 41. One end of the support part 41 is used for the connecting part 23 to be movably connected in the second direction Y, and the other end is connected to the scanning part 42. The scanning part 42 is electrically connected to the control mechanism 50. The scanning part 42 is arranged facing the conveyor belt 21. The scanning part 42 is used to acquire the indentation information of the sample.

[0111] With the cooperation of the support part 41 and the connecting part 23, the detection mechanism 40 is movable relative to the conveying mechanism 20 in the second direction Y, so that the spacing between adjacent detection mechanisms 40 can be easily adjusted to set an appropriate number of detection mechanisms 40 when dealing with different detection accuracy requirements.

[0112] Optionally, the support portion 41 and the connecting portion 23 are connected by a slide rail and slider, or a lead screw and nut, or a gear and rack, so that the support portion 41 can move relative to the connecting portion 23 in the second direction Y.

[0113] Optionally, the scanning unit 42 is arranged perpendicular to the conveyor belt 21 along the first direction X to improve the detection accuracy of the scanning unit 42.

[0114] Optionally, the scanning unit 42 can be a laser rangefinder, a laser scanner, a microwave rangefinder, etc.
