Description

Technical Field

[0001] This application relates to the field of fabric testing technology, specifically to an itching sensation tester. Background Technology

[0002] In real life, when yarns spun from short fibers such as wool, linen, and synthetic fibers are woven into fabric, the ends of these short fibers form many fuzzy fibers on the fabric surface. These fibers are relatively stiff and can cause an itchy sensation on the skin. Therefore, it is common to find that clothing worn close to the skin sometimes causes itching and discomfort. Thus, it is necessary to conduct itchiness tests on fabrics after production.

[0003] In existing technologies, the itch sensation test is obtained by rubbing the fiber end against the test surface and measuring the friction value. However, the friction value measured by this method is too small, and ordinary force sensors are unable to collect the force value change.

[0004] Therefore, existing testing methods need to be improved. Summary of the Invention

[0005] In view of this, this application provides an itching sensation tester to solve the technical problem.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An itching sensation tester includes: The enclosure has a platform; A placement plate capable of securing fabric to the platform; The drive mechanism is installed inside the housing; Test components connected to the drive mechanism; The driving mechanism can drive the moving plate to move. The test component is connected to the moving plate. The test component includes a metal wire. The driving mechanism drives the moving plate to move the metal wire, which can generate relative movement with the fabric, thereby testing the stimulation sensation of the fabric.

[0007] Furthermore, the drive mechanism includes: The stepper motor is installed inside the chassis of the enclosure; A transmission assembly connected to the output end of the stepper motor; A movable plate connected between the transmission assembly and the test assembly; A sliding assembly connected to the movable plate.

[0008] Furthermore, the drive mechanism also includes a coupling connecting the stepper motor and the transmission assembly.

[0009] Furthermore, the transmission assembly includes: A pair of fixed housings spaced apart within the chassis; A rotating shaft connected to the coupling; The first pulley fitted on the rotating shaft; A second pulley is connected to the first pulley via a belt.

[0010] Furthermore, the sliding component includes: Slide rails are installed inside the chassis; The mounting base is disposed inside the chassis; A guide block is connected to the lower end of the movable plate, and the guide block is slidably engaged with the slide rail; A movable block is connected between the lower end of the movable plate and the belt, and the movable block is slidably engaged with the fixed seat.

[0011] Furthermore, the test components include: Test head connected to the moving board; A sensor is installed inside the test head; A pair of fasteners for securing the metal wire.

[0012] Furthermore, the fastener includes: A fixing block installed inside the test head; A pressure plate connected to the side of the fixing block.

[0013] Furthermore, the two ends of the metal wire pass under the sensor, go around the bottom of the corresponding fixing block, and are then fixed to the side of the fixing block by the pressure plate.

[0014] Furthermore, the bottom of the test head is provided with a cover plate, and the cover plate has a through hole, through which the metal wire can rub against the fabric.

[0015] As can be seen from the above technical solution, the advantages of the present invention are: 1. In this application, the driving mechanism can drive the test head to move back and forth. A metal wire is installed at the lower end of the test head, and the fabric to be tested is fixed below the metal wire. The metal wire contacts the fabric surface. By moving the metal wire back and forth, it can rub against each protruding fiber on the fabric surface. The subtle vibrations generated when the fibers rub against the metal wire can be collected by an audio acquisition sensor. The signal is then amplified and digitized by a signal conversion sensor and recorded as an audio signal file in the test analysis system. The signal is represented by spikes. All peaks greater than a configurable threshold are identified and counted. The sum of all electronic peaks is the itch sensation test value. This application is not only easy to operate but also has high testing efficiency. Attached Figure Description

Detailed Implementation

[0028] 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 embodiments and accompanying drawings. Here, the illustrative embodiments and their descriptions are used to explain this application, but are not intended to limit it.

[0029] refer to Figures 1 to 10 ,like Figure 1 and Figure 2 As shown, this embodiment provides an itch sensation tester. Compared with the problems of existing testing devices, this application makes the test results more accurate and efficient. The itch sensation tester includes: a housing, a placement plate 3, a drive mechanism 4, and a test component 5. The housing includes a base 1 and a chassis 2, with the chassis 2 connected to the base 1. The base 1 has a platform on the right side of the chassis 2. The placement plate 3 can fix the fabric on the platform. The drive mechanism 4 is disposed inside the chassis 2. The test component 5 is connected to the drive mechanism 4. The drive mechanism 4 can drive a moving plate 49 to move. The test component 5 is connected to the moving plate 49. The test component 5 includes a metal wire 55. The drive mechanism 4 drives the moving plate 49 to move the metal wire 55, which can generate relative movement with the fabric, thereby testing the irritation sensation of the fabric.

[0030] Preferably, in this embodiment of the application, the four corners of the placement plate 3 are provided with limiting screw holes 31 so as to fix the placement plate 3 on the platform. During the test, the fabric is laid flat on the placement plate 3. Since the fibers of the fabric are raised, the metal wire 55 will sweep across the surface of the fabric when it moves, so the metal wire 55 will move relative to the fibers of the fabric.

[0031] like Figure 2 As shown, the drive mechanism 4 includes: a stepper motor 41, a transmission assembly 43, a moving plate 49, and a sliding assembly. The stepper motor 41 is disposed inside the housing 2 of the housing. The transmission assembly 43 is connected to the output end of the stepper motor 41. The moving plate 49 is connected between the transmission assembly 43 and the test assembly 5. The sliding assembly is connected to the moving plate 49.

[0032] Preferably, in this embodiment of the application, the drive mechanism 4 further includes a coupling 42, which is connected between the stepper motor 41 and the transmission assembly 43.

[0033] like Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the transmission assembly 43 includes: a pair of fixed housings 431, a rotating shaft 432, a first pulley 433 and a second pulley 435. The pair of fixed housings 431 are arranged at intervals in the housing 2. The rotating shaft 432 is connected to the coupling 42. The first pulley 433 is sleeved on the rotating shaft 432. The second pulley 435 is connected to the first pulley 433 through a belt 434.

[0034] Preferably, in this embodiment of the application, a through hole 4311 is provided on the rear side of the fixed housing 431, and the belt 434 extends rearward after passing through the through hole 4311.

[0035] like Figure 6 and Figure 7 As shown, the first pulley 433 is rotatably mounted in the front fixed housing 431 via the rotating shaft 432, the second pulley 435 is provided with a drive shaft 436, the drive shaft 436 is installed in the rear fixed housing 431, and the fixed seat 44 is connected between the pair of fixed housings 431.

[0036] like Figure 3 As shown, the sliding assembly includes: a slide rail 46, a fixed base 44, a guide block 48, and a moving block 45. The slide rail 46 is disposed inside the housing 2. The fixed base 44 is spaced apart from the slide rail 46 and guides the belt 434. The guide block 48 is connected to the lower end of the moving plate 49 and slides in cooperation with the slide rail 46. The moving block 45 is connected between the lower end of the moving plate 49 and the belt 434 and slides in cooperation with the fixed base 44. By setting the moving block 45 and the guide block 48 at the lower end of the moving plate 49, the moving plate 49 can move back and forth more smoothly, thus making the test results more accurate.

[0037] Preferably, in this embodiment of the application, the sliding component further includes a bracket 47, which is located on the left side of the fixed base 44, and the slide rail 46 is disposed on the bracket 47.

[0038] In this embodiment, the stepper motor 41 drives the rotating shaft 432 to rotate through the coupling 42. Then, the first pulley 433 drives the second pulley 435 to rotate through the belt 434. The rotation of the belt 434 will drive the moving block 45 to move, thereby driving the test head 51 to move back and forth through the moving plate 49.

[0039] like Figure 2 and Figure 8As shown, the test assembly 5 includes: a test head 51, a sensor 53, and a pair of fixing members 54. The test head 51 is connected to the moving plate 49 via a mounting rod 52. The sensor 53 is disposed inside the test head 51 and is used to collect the signal generated by the vibration when the fabric comes into contact with the metal wire. The pair of fixing members 54 are symmetrically disposed at the left and right ends inside the test head 51, and the metal wire 55 can be fixed between the pair of fixing members 54.

[0040] like Figure 9 As shown, the fixing member 54 includes a fixing block 541 and a pressure plate 542. The fixing block 541 is installed inside the test head 51 by a height adjusting screw 546. The height of the fixing block 541 can be adjusted by rotating the height adjusting screw 546, thereby adjusting the distance between the metal wire 55 and the fabric. The pressure plate 542 is connected to the side of the fixing block 541.

[0041] Preferably, in this embodiment of the application, a first mounting plate 545 is provided on the top of the test head 51, and the lower end of the height adjusting screw 546 passes through the first mounting plate 545 and the test head 51 in sequence and is connected to the fixing block 541, thereby fixing the fixing block 541 inside the test head 51.

[0042] Furthermore, a second mounting plate 543 is provided on the right side of the test head 51, and the mounting screws 544 are connected to the test head 51 via the second mounting plate 543 and then to the fixing block 541 on the right side.

[0043] In this embodiment, the two ends of the metal wire 55 pass under the sensor 53, go around the bottom of the corresponding fixing block 541, and are then fixed to the side of the fixing block 541 by the pressure plate 542.

[0044] Preferably, in this embodiment of the application, a first threaded hole 5411 is provided on the outer side of the fixing block 541, and a second threaded hole 5421 is provided on the pressure plate 542. Locking screws are provided in the first threaded hole 5411 and the second threaded hole 5421. By providing locking screws, the end of the metal wire 55 can be fixed between the fixing block 541 and the pressure plate 542.

[0045] Preferably, in this embodiment of the application, the bottom of the test head 51 is provided with a cover plate 511, and the cover plate 511 has a through hole 5111, through which the metal wire 55 can rub against the fabric.

[0046] Preferably, in this embodiment of the application, a movable slot 21 is provided on the right side of the chassis 2, and the right end of the movable plate 49 passes through the movable slot 21 and is connected to the test head 51.

[0047] Working principle: The two ends of the metal wire 55 are firmly fixed between the corresponding fixing block 541 and the pressure plate 542. The height of the metal wire 55 is manually adjusted by the height adjusting screw 546, so that the metal wire 55 contacts the fabric. The metal wire 55 can rub against each protruding fiber on the fabric, and the tension on the metal wire is determined by its deflection when interacting with each fiber. The stepper motor 41 is started, which drives the test head 51 to move back and forth through the moving plate 49, thus moving the metal wire 55 back and forth. Figure 10 As shown, the metal wire 55 moves and rubs against the fabric. The subtle vibrations generated by the friction between the fabric fibers and the metal wire 55 are collected by an audio acquisition sensor. These tiny audio signals are amplified and digitized by a signal conversion sensor and recorded as an audio signal file in the test and analysis system. The signal is represented by spikes. All peaks exceeding a configurable threshold are identified and counted. The sum of the electronic peaks observed by the metal wire 55 is the itch sensation test value.
