Description

Technical Field

[0001] This utility model belongs to the field of fabric strength testing technology, specifically relating to a device for testing the strength of clothing fabrics. Background Technology

[0002] In the field of garment manufacturing, the strength of the fabric is a key factor that determines the quality and durability of the garment. Different types of garments are subjected to various complex external forces during wear, such as stretching, tearing, friction, and varying degrees of compression. Accurately testing the strength of garment fabrics is crucial for ensuring the performance of garments under normal use conditions, extending the service life of garments, and improving the consumer wearing experience.

[0003] Currently, there are various devices available on the market for testing the strength of clothing fabrics. Conventional fabric strength testing equipment mainly focuses on performing simple unidirectional tensile tests on the fabric. By fixing both ends of the fabric, gradually increasing tension is applied until the fabric breaks, thereby obtaining the tensile strength data of the fabric.

[0004] However, this traditional testing method has obvious limitations. In actual wear, the external force on clothing fabric is not in one direction, but a complex pulling force from different positions. Existing devices cannot fully simulate such actual stress conditions. Data obtained by relying solely on unidirectional tensile testing is difficult to accurately reflect the true strength performance of the fabric under diverse wearing scenarios, resulting in an incomplete and inaccurate assessment of the strength of clothing fabric.

[0005] In the process of fabric strength testing, the compression test is also an important testing dimension. It can reflect the performance of the fabric when subjected to vertical pressure, such as wrinkle resistance and compression deformation recovery ability. However, most existing fabric strength testing devices often neglect the integration of the compression test function. This results in the lack of key information about the fabric's ability to cope with vertical pressure when evaluating fabric strength, and cannot provide a complete and reliable technical basis for the selection and application of fabrics in the garment production process.

[0006] In summary, existing garment fabric strength testing devices have significant shortcomings in their testing functions and cannot meet the actual needs for comprehensive and accurate testing of fabric strength. Utility Model Content

[0007] The purpose of this invention is to provide a garment fabric strength testing device that can perform pull tests on fabrics at different locations, improving the comprehensiveness and accuracy of pull strength testing. It also integrates a compression test function to supplement fabric compression performance data, providing a complete basis for fabric strength assessment.

[0008] The specific technical solution adopted by this utility model is as follows:

[0009] A garment fabric strength testing device includes a base plate. Bottom moving columns are laterally slidably connected to the four corners of the top of the base plate. A top moving column is located at the top of each bottom moving column. Two bottom moving columns on the same side are threadedly connected to a first threaded rod and a second threaded rod, respectively. The threads of the first and second threaded rods have opposite directions and are fixedly connected. Two mounting plates are fixed to the top of the base plate, and each mounting plate is rotatably connected to one of the first threaded rods and the other to the other. A first motor is mounted on one side of one of the mounting plates, and the output end of the first motor passes through the mounting plate and connects to one of the second threaded rods. A first synchronization component is installed between the two first threaded rods.

[0010] Each of the multiple bottom moving columns has a fixed bracket at its top, and the multiple top moving columns are vertically slidably connected within the multiple fixed brackets. Two top moving columns at the same end are respectively threaded with a third threaded rod and a fourth threaded rod. The threads of the third threaded rod and the fourth threaded rod have opposite directions and are fixedly connected. The top of the base plate is slidably connected with multiple mounting plates, and each mounting plate is rotatably connected to the end of the third threaded rod and the fourth threaded rod. A second motor is mounted on one side of one of the mounting plates. The output end of the second motor passes through the mounting plate and is connected to one of the third threaded rods. A second synchronization component is installed between the two fourth threaded rods.

[0011] The first synchronization component includes a first transmission wheel fixed to the ends of the two first threaded rods, and the two first transmission wheels are driven by a first transmission belt.

[0012] The second synchronization component includes a second transmission wheel fixed to the ends of the two fourth threaded rods, and the two second transmission wheels are driven by a second transmission belt. A downward transmission wheel is provided on the inner side of the bottom of the second transmission belt. Both ends of the downward transmission wheel are rotatably connected to a connecting block, and a spring is fixed between the connecting block and the base plate.

[0013] Each of the top moving columns is provided with a clamping structure, which is a clamping block threadedly connected to the top moving column.

[0014] Both sides of the top of the base plate are fixed with fixing plates. A fifth threaded rod and a limiting rod are provided between the two fixing plates and near the top. The fifth threaded rod is rotatably connected to the two fixing plates, and the limiting rod is fixedly connected to the two fixing plates. An assembly plate is slidably connected to the outer side of the limiting rod, and the assembly plate is threadedly connected to the fifth threaded rod.

[0025] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0026] like Figures 1-5 As shown, a garment fabric strength testing device includes a base plate 1. Bottom moving columns 2 are slidably connected to the four corners of the top of the base plate 1. Top moving columns 3 are provided on the top of the bottom moving columns 2. Further, clamping structures are provided on the top of the multiple top moving columns 3. The clamping structures are clamping blocks 28 threadedly connected to the top moving columns 3. The fabric body 29 is pierced through the four corners or directly clamped to the clamping blocks 28, thereby fixing the fabric body 29. The two bottom moving columns 2 on the same side are respectively threadedly connected to the first threaded rod 4 and the second threaded rod 5. The threads of the first threaded rod 4 and the second threaded rod 5 have opposite directions, and the first threaded rod 4 and the second threaded rod 5 are fixedly connected. Two mounting plates 6 are fixed on the top of the base plate 1, and the two mounting plates 6 are rotatably connected to the two first threaded rods 4 and the two second threaded rods 5 respectively. A first motor 7 is installed on one side of one of the mounting plates 6. The output end of the first motor 7 passes through the mounting plate 6 and is connected to one of the second threaded rods 5. A first synchronization component is installed between the two first threaded rods 4.

[0027] When a strength test is required on the fabric body 29, the fabric body 29 can be clamped on the clamping block 28, and the first motor 7 can be driven. The output of the first motor 7 will drive one of the first threaded rods 4 and the second threaded rod 5 to rotate. Through the setting of the first synchronization component, the two first threaded rods 4 and the two second threaded rods 5 will rotate simultaneously. Since the threads of the first threaded rods 4 and the second threaded rods 5 have opposite directions, the two bottom moving columns 2 on the same side will move simultaneously in opposite directions. This allows the bottom moving columns 2 to drive the top moving column 3 to move, thereby allowing lateral pulling on the fabric body 29 to check for loose threads or deformation. This enables the strength test of the fabric body 29. (Refer to the attached diagram.) Figure 3 The first synchronization component includes a first transmission wheel 8 fixed to the ends of two first threaded rods 4, and the two first transmission wheels 8 are driven by a first transmission belt 9. When one of the first threaded rods 4 rotates, it can drive one of the first transmission wheels 8 to rotate, and through the transmission of the first transmission belt 9, it can drive the other first threaded rod 4 to rotate, thereby realizing the synchronous rotation of the two first threaded rods 4 and the second threaded rod 5. The inner side of the first transmission belt 9 is provided with teeth, and the outer side of the first transmission wheel 8 is also provided with teeth, so that the first transmission wheel 8 and the first transmission belt 9 can mesh, making the transmission effect of the first transmission belt 9 better.

[0028] See attached document Figures 2-3 Each of the multiple bottom moving columns 2 has a fixed bracket 10 at its top, and the multiple top moving columns 3 are vertically slidably connected within the multiple fixed brackets 10. The two top moving columns 3 at the same end are respectively threaded with a third threaded rod 11 and a fourth threaded rod 12. The threads of the third threaded rod 11 and the fourth threaded rod 12 have opposite directions and are fixedly connected. The top of the base plate 1 is slidably connected with multiple mounting plates 13, and each mounting plate 13 is rotatably connected to the end of the third threaded rod 11 and the fourth threaded rod 12. A second motor 14 is mounted on one side of one of the mounting plates 13. The output end of the second motor 14 passes through the mounting plate 13 and is connected to one of the third threaded rods 11. A second synchronization component is installed between the two fourth threaded rods 12.

[0029] When a vertical pull test is required on the fabric body 29, the second motor 14 can be driven, causing the output end of the second motor 14 to drive one of the third threaded rods 11 and the fourth threaded rod 12 to rotate. Through the second transmission assembly, the two third threaded rods 11 and the fourth threaded rod 12 rotate synchronously, causing multiple top moving columns 3 to slide within the fixed frame 10. Because the threads of the third threaded rods 11 and the fourth threaded rods 12 have opposite directions, the two top moving columns 3 on the same side move simultaneously in opposite directions, allowing the top moving columns 3 to pull the fabric body 29 vertically. The user can then check whether the fabric body 29 shows signs of unraveling or deformation, thus enabling a strength test of the fabric body 29. (Refer to the attached diagram.) Figure 3 The second synchronization component includes a second transmission wheel 15 fixed to the ends of two fourth threaded rods 12, and the two second transmission wheels 15 are driven by a second transmission belt 16. A downward transmission wheel 17 is provided on the inner side of the bottom of the second transmission belt 16. Both ends of the downward transmission wheel 17 are rotatably connected to connecting blocks 18. A spring 19 is fixed between the connecting block 18 and the base plate 1. With this arrangement, when one of the fourth threaded rods 12 rotates, it can drive one of the second transmission wheels 15 to rotate, and through the transmission of the second transmission belt 16, drive the other fourth threaded rod 12 to rotate. The rotation of the four threaded rods 12 enables the synchronous rotation of the two third threaded rods 11 and the fourth threaded rod 12. The inner side of the second transmission belt 16 is provided with teeth, and the outer side of the second transmission wheel 15 is also provided with teeth, thus enabling the second transmission wheel 15 and the second transmission belt 16 to mesh, resulting in better transmission efficiency. When the first threaded rod 4 and the second threaded rod 5 drive the two top moving columns 3 to move laterally, the third threaded rods 11 and 12 will also move accordingly, thereby driving the mounting plate 13 to move. (See attached diagram.) Figure 4 By setting the second transmission belt 16 in a triangle, when the two top moving columns 3 move, the second transmission belt 16 becomes longer, and the lower second transmission belt 16 moves upward, thereby driving the lower pressure transmission wheel 17 to move upward and driving the spring 19 to stretch. After the test is completed, the spring 19 retracts and drives the lower pressure transmission wheel 17 to pull the lower second transmission belt 16 downward, so that the second transmission belt 16 can stably achieve the transmission effect.

[0030] The first motor 7 and the second motor 14 can be started synchronously, thereby pulling the fabric body 29 in all directions for testing.

[0031] See attached document Figure 5The bottom plate 1 has two fixed plates 20 on both sides of the top. A fifth threaded rod 21 and a limiting rod 22 are provided between the two fixed plates 20 and near the top. The fifth threaded rod 21 is rotatably connected to the two fixed plates 20, and the limiting rod 22 is fixedly connected to the two fixed plates 20. An assembly plate 24 is slidably connected to the outside of the limiting rod 22, and the assembly plate 24 is threadedly connected to the fifth threaded rod 21. A third motor 23 is fixed to one side of one of the fixed plates 20, and the output end of the third motor 23 passes through the fixed plate 20 and is connected to the end of the fifth threaded rod 21. A first electric push rod 25 is installed at the bottom of the assembly plate 24, and a second electric push rod 26 is slidably connected to the bottom of the assembly plate 24. The stroke rod of the first electric push rod 25 is connected to the second electric push rod 26, and the stroke rod of the second electric push rod 26 is vertically downward.

[0032] When a pressing test is required on the fabric body 29, the second electric push rod 26 can be driven, causing its stroke rod to move downwards and press against the fabric body 29, compressing it until it deforms. After deformation, its recovery is observed, thus testing the fabric body 29's behavior during pressing. When the position of the second electric push rod 26 needs to be changed, the first electric push rod 25 can be driven, changing the vertical position of the second electric push rod 26 and driving the third motor 23. This third motor 23 then rotates the fifth threaded rod 21, and... The fifth threaded rod 21 is threadedly connected to the assembly plate 24, and the assembly plate 24 is slidably connected to the limiting rod 22, allowing the assembly plate 24 to slide on the limiting rod 22. This allows the assembly plate 24 to change the position of the second electric push rod 26 when it moves, thus enabling pressing tests on different positions of the fabric body 29. The stroke rod of the second electric push rod 26 is threadedly connected to an end head 27. By setting the end head 27, the user can replace different end heads 27, such as conical or circular, thereby enabling pressing tests on various shapes of the fabric body 29.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
