Description

Technical Field

[0001] This application relates to the technical field of leather testing equipment, and in particular to a tooling for testing the stiffness and softness of leather. Background Technology

[0002] The stiffness and softness of leather is an important indicator of leather product quality. During use, leather that is too stiff or too soft can cause quality problems such as cracking, affecting its lifespan. Therefore, during the production process, it is necessary to use leather stiffness and softness testing fixtures to test the stiffness and softness of leather products to determine whether each product meets quality standards.

[0003] Existing leather stiffness and softness testing fixtures typically involve manually pushing the sample placed on the fixture. When the sample reaches a certain tilt angle, the displacement and other relevant values ​​of the sample are measured, and these values ​​characterize the sample's hardness. However, this manual pushing method has a low degree of automation, is wasteful of manpower, and has low measurement accuracy, leading to inaccurate test results. Furthermore, only one sample can be tested at a time, making parallel comparison of samples impossible, thus limiting the scope of sample testing. Utility Model Content

[0004] Therefore, it is necessary to provide an automated leather stiffness and softness testing fixture that can perform parallel comparative testing and improve the accuracy of stiffness and softness test results.

[0005] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0006] A leather stiffness-softness testing fixture, the leather stiffness-softness testing fixture comprising:

[0007] A test stand has a conveyor surface and a test surface. The test surface is connected to one end of the conveyor surface and is inclined downward relative to the conveyor surface along the height direction of the test stand, forming an angle with the conveyor surface.

[0008] The conveying mechanism is configured to have at least two conveying mechanisms arranged side by side, each conveying mechanism being capable of conveying different leather materials;

[0009] Distance sensors are installed on the conveyor table, and the number of distance sensors corresponds one-to-one with the number of conveying mechanisms. The distance sensors are used to detect the distance of movement of the leather material on the corresponding conveying mechanism.

[0010] A position sensor is installed on the test platform, and the number of the position sensors corresponds one-to-one with the number of the conveying mechanisms. The position sensor is used to detect the position of the corresponding leather material on the test platform.

[0011] It is understood that by setting up at least two conveying mechanisms side by side, this application enables the leather stiffness testing fixture to simultaneously test at least two leather materials and to perform parallel tests on the at least two simultaneously tested leather materials, allowing for comparative analysis. Simultaneously, the conveying mechanisms achieve automatic transport of the leather materials, and position and distance sensors automatically determine the movement distance and position of the leather materials, thereby automatically achieving the testing of leather material hardness. This not only saves manpower but also effectively improves the accuracy of test results.

[0012] In one embodiment, each of the conveying mechanisms includes a drive unit and a conveyor belt. The drive unit is disposed inside the test bench, and the conveyor belt is mounted on the conveying table surface and connected to the drive unit so that it can move under the drive of the drive unit.

[0013] The position sensor is signal-connected to the drive unit.

[0014] In one embodiment, each of the conveying mechanisms further includes a baffle mounted on the conveyor belt for limiting the leather material, and the position sensor is used to detect the position of the corresponding baffle on the test platform.

[0015] Understandably, the baffle can locate the initial and stopping positions of the leather material, making the distance the leather material moves more accurately. Furthermore, the position of the corresponding baffle on the test platform can be detected by the position sensor to determine the conveying distance of the leather material, which helps to improve the accuracy of the test.

[0016] In one embodiment, the test bench has an operation panel, which is located on the side of the conveyor table and connected to both the conveyor table and the test table.

[0017] The operation panel is equipped with at least two distance display screens, each of which is connected to and signal-connected to each of the distance sensors, for displaying the distance of the leather material movement detected by the distance sensors.

[0018] Understandably, being able to directly display the distance of the leather material movement detected by the distance sensor on the distance display screen makes the test results of the leather stiffness and softness testing fixture more intuitive. It eliminates the need for manual measurement, data reading, and recording, making the operation more convenient and the results more accurate.

[0019] In one embodiment, the operation panel is provided with a distance display reset button that corresponds one-to-one with the distance display screen. The distance display reset button is electrically connected to the distance display screen and can reset the value displayed on the distance display screen to zero.

[0020] In one embodiment, the operation panel is provided with at least two speed displays, each speed display corresponding to one of the conveyor belts and used to display the speed value of the conveyor belt.

[0021] In one embodiment, the operation panel is further provided with at least two speed adjustment knobs, each speed adjustment knob corresponding to a speed display screen and electrically connected to the corresponding drive component, for controlling the drive component to adjust the speed of the conveyor belt.

[0022] Understandably, setting a speed adjustment knob allows the speed of the drive component to be adjusted, thereby enabling the leather stiffness and softness testing fixture to adapt to different test conditions for different samples.

[0023] In one embodiment, the operation panel is further provided with at least two conveyor belt position adjustment knobs, each conveyor belt position adjustment knob corresponding to one of the driving components, and electrically connected to the corresponding driving component to control the driving component to adjust the position of the conveyor belt on the test platform.

[0024] In one embodiment, the operation panel is further provided with a main switch and at least two sub-switches. The main switch is used to control the opening and closing of the test bench, and each sub-switch corresponds to one of the conveying mechanisms and controls the opening and closing of the conveying mechanism.

[0025] Understandably, setting at least two sub-switches, with each sub-switch corresponding to a conveyor mechanism, allows each conveyor mechanism to operate independently, enabling the fixture to adapt to single or multiple leather material tests, and allowing testers to flexibly select the number of test samples.

[0026] In one embodiment, the distance sensor is configured as a laser rangefinder or an infrared sensor; and / or, the position sensor is configured as a light-controlled switch, an inductive sensor, or a proximity switch.

[0027] Compared with existing technologies, this application, by setting up at least two conveying mechanisms side by side, enables the leather stiffness testing fixture to simultaneously test at least two leather materials and to perform parallel testing on the at least two simultaneously tested leather materials, achieving comparative analysis. Simultaneously, the conveying mechanisms achieve automatic transport of the leather materials, and position and distance sensors automatically determine the movement distance and position of the leather materials, thereby automatically realizing the testing of leather material hardness. This not only saves manpower but also effectively improves the accuracy of test results. Attached Figure Description

[0037] Please see Figures 1 to 2This application provides a leather stiffness and softness testing fixture 100, which includes a testing table 10, a conveying mechanism 20, a distance sensor 30, and a position sensor 40. The testing table 10 has a conveying surface 11 and a testing surface 12. The testing surface 12 is connected to one end of the conveying surface 11 and is inclined downwards relative to the conveying surface 11 along the height direction of the testing table 10, forming an angle with the conveying surface 11. The conveying mechanism 20 is configured with at least two conveying mechanisms 20 arranged side-by-side. Each conveyor mechanism 20 is configured to transport different leather materials 101. Distance sensors 30 are mounted on the conveyor platform 11, with the number of distance sensors 30 corresponding to the number of conveyor mechanisms 20. The distance sensors 30 detect the distance traveled by the corresponding leather material 101 on the conveyor mechanism 20. Position sensors 40 are mounted on the test platform 12, with the number of position sensors 40 corresponding to the number of conveyor mechanisms 20. The position sensors 40 detect the position of the corresponding leather material 101 on the test platform 12. Thus, by setting at least two conveyor mechanisms 20 side-by-side, the leather stiffness testing fixture 100 can simultaneously test at least two leather materials 101 and perform parallel tests on at least two simultaneously tested leather materials 101 for comparative analysis. Simultaneously, the conveyor mechanisms 20 enable automatic transport of the leather materials 101, and the distance sensors 30 and position sensors 40 automatically determine the position and travel distance of the leather materials 101, thereby automatically testing the hardness of the leather materials 101. This not only saves manpower but also effectively improves the accuracy of the test results.

[0038] Here, the distance sensor 30 and the position sensor 40 each correspond one-to-one with the number of conveying mechanisms 20, so that each conveying mechanism 20 can operate independently or simultaneously and can read and record data separately. Therefore, taking the number of conveying mechanisms 20 as an example, the number of distance sensors 30 and position sensors 40 will not be repeated in the following description.

[0039] Optionally, the number of conveying mechanisms 20 can be two, three, or five, depending on the actual situation. In this embodiment, the number of conveying mechanisms 20 is set to two.

[0040] Please refer to Figure 1 and Figure 2 Each conveying mechanism 20 includes a drive unit 21 and a conveyor belt 22. The drive unit 21 is located inside the test bench 10, and the conveyor belt 22 is installed on the conveying table 11. The conveyor belt 22 is connected to the drive unit 21 so that the leather material 101 to be tested can be conveyed under the drive of the drive unit 21.

[0041] Here, the drive unit 21 is connected to the position sensor 40. When the position sensor 40 detects that the leather material 101 has reached a certain position, it can stop the drive unit 21 by transmitting a signal.

[0042] Furthermore, each conveying mechanism 20 also includes a baffle 23, which is mounted on the conveyor belt 22 to limit the movement of the leather material 101. The position sensor 40 is used to detect the position of the corresponding baffle 23 on the test platform 12. Here, by positioning the baffle 23, the movement distance of the leather material 101 can be made more accurate. Then, by measuring the displacement distance of the baffle by the distance sensor, the leather hardness can be tested, which helps to improve the accuracy of the test.

[0043] like Figure 1 As shown, for ease of operation and testing, the test bench 10 has an operation panel 13, which is located on the side of the conveyor table 11 and connected to both the conveyor table 11 and the test table 12. The operation panel 13 has at least two distance displays 131, each connected to and signal-connected to a distance sensor 30, displaying the distance traveled by the leather material 101 detected by the distance sensor 30. This allows the distance traveled by the leather material 101 detected by the distance sensor 30 to be directly displayed on the distance displays 131, eliminating the need for manual data reading and recording, making operation more convenient and the results more accurate.

[0044] Here, the test platform 10 is in the shape of a right trapezoid, with the upper base of the right trapezoid configured as a conveyor platform 11, the side configured as an operation panel 13, and the hypotenuse of the right trapezoid configured as a test platform 12; and the angle between the test platform 12 and the lower base of the right trapezoid can be set to 45°.

[0045] Furthermore, the operation panel 13 is also provided with a distance display reset button 132 corresponding to the distance display screen 131. The distance display reset button 132 is electrically connected to the distance display screen 131 and can reset the value displayed on the distance display screen 131 to zero. This operation makes it convenient for the tester to retest and read the value on the distance display screen 131.

[0046] Please continue to refer to this. Figure 1 The control panel 13 is equipped with at least two speed displays 133, each corresponding to a conveyor belt 22 and used to display the speed value of the conveyor belt 22. This allows the speed displays 133 to show the real-time operating speed of the conveyor mechanism 20, making operation more convenient for testing workers.

[0047] Specifically, the speed of the conveyor belt 22 can be detected by a speed sensor (not shown). The speed display screen 133 is electrically connected to the speed sensor, and the speed measured by the speed sensor can be displayed on the speed display screen 133.

[0048] Furthermore, the operation panel 13 is also equipped with at least two speed adjustment knobs 134, each speed adjustment knob 134 corresponding to a speed display screen 133, and electrically connected to the corresponding drive component 21 to control the operating speed of the drive component 21. It is understood that setting the speed adjustment knobs 134 makes the operating speed of the drive component 21 adjustable, thereby enabling the leather stiffness and softness testing fixture 100 to adapt to different test conditions for different samples.

[0049] Preferably, the operation panel 13 is also provided with at least two conveyor belt position adjustment knobs 135, each corresponding to a drive unit 21 and electrically connected to the corresponding drive unit 21, for controlling and adjusting the position of the conveyor belt 22 on the test platform 12 via the drive unit 21. Thus, the initial position of the leather material 101 on the conveyor belt 22 can be adjusted by rotating the conveyor belt position adjustment knobs 135, making the leather stiffness and softness testing fixture 100 suitable for stiffness and softness testing of leather materials 101 of various lengths and hardnesses.

[0050] like Figure 1 As shown, the operation panel 13 is also equipped with a main switch 136 and at least two branch switches 137. The main switch 136 is used to control the opening and closing of the test bench 10, and each branch switch 137 corresponds to a drive unit 21 and controls the opening and closing of the drive unit 21. In this way, each conveying mechanism 20 can operate independently, so that the fixture can be adapted to testing a single leather material 101 or multiple leather materials 101, allowing the testing operator to flexibly select the number of test samples.

[0051] Please continue to refer to this. Figure 1 In one embodiment, the operation panel 13 integrates a distance display screen 131, a distance display reset button 132, a speed display screen 133, a speed adjustment knob 134, a conveyor belt position adjustment knob 135, a main switch 136, and individual switches 137. The positions of the integrated components are not limited and can be determined according to actual conditions. Here, except for the main switch 136, which can be set to one, the number of other components corresponds one-to-one with the number of conveyor mechanisms 20, and each component can operate independently with each conveyor mechanism 20. Thus, by setting all the operating components on the same operation panel 13, operation is convenient.

[0052] In one embodiment, the distance sensor 30 can be configured as a laser rangefinder or an infrared sensor. In this embodiment, the distance sensor 30 is configured as a laser rangefinder, which can accurately measure the movement distance of the baffle 23 using laser technology.

[0053] Preferably, the position sensor 40 can be configured as a light-controlled switch, an inductive sensor, or a proximity switch.

[0054] In this embodiment, the position sensor 40 is configured as a photosensitive switch. The stiffness and softness test of the leather material 101 is performed by moving the leather material 101 on the conveyor table 11. When the other end of the leather material 101 away from the baffle 23 is about to or has already contacted the test table 12, the distance display screen 131 displays the distance the leather material 101 has moved on the conveyor table 11. The larger the distance value, the higher the hardness of the leather material 101. Therefore, the photoelectric effect of the photoresistor in the photosensitive switch can accurately sense the state that the other end of the leather material 101 away from the baffle 23 is about to or has already contacted the test table 12, and control the drive unit 21 in time to stop its operation immediately, thereby improving the accuracy of the test results.

[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
