Description

Technical Field

[0001] This utility model belongs to the field of fabric production technology and relates to a scratch and fold resistance testing device for tent fabric. Background Technology

[0002] Tent fabric is the main material used to make tents, and its performance directly affects the tent's waterproofness, breathability, and durability. Among these, the scratch and fold resistance of the tent fabric directly affects the tent's lifespan. During the tent fabric's production process, its scratch and fold resistance are tested to ensure a good lifespan. Therefore, it is necessary to design a scratch and fold resistance testing device for tent fabric to facilitate testing. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a scratch and fold resistance testing device for tent fabric.

[0004] The objective of this utility model can be achieved through the following technical solution: A scratch and folding resistance testing device for tent fabric, comprising a frame, characterized in that a fixing mechanism for fixing the ends of the fabric and a folding mechanism for testing the folding of the fabric are correspondingly installed from top to bottom at the center of the frame. The fixing mechanism includes a mounting component one, on which a set of push rod motors one is horizontally mounted opposite each other. The rod of the push rod motors one is equipped with corresponding clamping components one and two. The folding mechanism includes a rotary motor, which is horizontally mounted on the frame. The output shaft of the rotary motor is connected to the mounting component two. A set of push rod motors 2 are horizontally mounted opposite each other. The rods of push rod motors 2 are equipped with corresponding clamping parts 3 and 4. A scraping mechanism for fabric scratch resistance testing is also provided between the fixing mechanism and the folding mechanism. The scraping mechanism includes push rod motors 3 and 4, which are horizontally mounted opposite each other on both sides of the central axis of the fixing mechanism and the folding mechanism. The rod of push rod motor 3 is equipped with a support for fabric support, and the rod of push rod motor 4 is equipped with a mounting part 3. A grinding wheel is rotatably mounted on the mounting part 3 and connected to a drive motor. A base is installed at the bottom of the frame.

[0005] The working principle of this utility model is as follows: One end of the tent fabric strip to be tested for scratch resistance and folding endurance is placed between clamping member one and clamping member two, and clamped and locked by push rod motor one. Then, the remaining part of the tent fabric strip is stretched vertically downwards to a vertical position. Clamping member three and clamping member four are clamped and fixed by push rod motor two. Then, the installation member two is rotated back and forth by a rotary motor to test the folding endurance of the tent fabric strip. After the folding endurance test is completed, a new tent fabric strip of the same type is replaced in the above manner. Then, the support member and the grinding wheel are pushed out by push rod motor three and push rod motor four and come into contact with the tent fabric strip. Then, the grinding wheel is controlled by the drive motor to rotate and grind in conjunction with the support member, thereby conducting a scratch resistance test.

[0006] The surfaces of clamping parts one, two, three and four are all provided with wavy bends, and a rubber layer is provided on the contact surface with the fabric.

[0007] The above structure increases friction with the fabric, thus better locking the tent fabric in place.

[0008] The mounting component is slidably installed in a groove on the frame, and a buffer spring is installed between the bottom of the mounting component and the groove.

[0009] With the above structure, when the fabric is tested for folding resistance, a certain amount of flexibility is provided by the buffer spring, making it more closely resemble the actual folding situation.

[0010] The grinding wheel is mounted on mounting component three via a detachable structure.

[0011] The above structure makes it easy to replace grinding wheels made of different materials.

[0012] A protective layer is provided at the point where the bottom of the slide groove contacts the mounting component.

[0013] The above structure serves as a buffer and protection mechanism.

[0014] Compared with existing technologies, this tent fabric scratch and fold resistance testing device has the following advantages: This utility model integrates a folding mechanism, a scratching mechanism, and a fixing mechanism in both the horizontal and vertical directions, which can effectively test the scratch and fold resistance of tent fabric.
