Description

Technical Field

[0001] This invention relates to the field of linear abrasion testing machines, and more particularly to a device for testing the abrasion resistance of textiles. Background Technology

[0002] The linear abrasion tester is suitable for testing the abrasion resistance of products such as plastics, automotive parts, rubber, leather and textiles, electroplating, freely detachable components, paints, and printed patterns. It can be used to evaluate the abrasion resistance of products, as well as their scratch resistance and color transfer.

[0003] Existing abrasion resistance testing devices for textiles use fixed blocks to fix the material in a point-like manner. However, due to the high surface friction of textiles and the fact that textiles are woven by intertwining threads, the strength of individual threads in the textile is insufficient. When a single thread breaks, the textile will move with the grinding head, making it impossible to continue the test. Therefore, a new abrasion resistance testing device for textiles is proposed to solve the above problems. Summary of the Invention

[0004] This invention provides a device for testing the abrasion resistance of textiles, which solves the above-mentioned technical problems.

[0005] To solve the above-mentioned technical problems, the present invention provides a device for testing the abrasion resistance of textiles, comprising a body, a transmission box at the upper end of the body, a movable plate connected to the side of the transmission box, a grinding head fixed on the surface of the movable plate, a fixed seat on the side of the body, a limit frame sleeved on the upper end of the fixed seat, a sliding groove and a positioning hole on the side of the fixed seat, a pressing rod slidably connected inside the sliding groove, a fixing bolt slidably connected to the surface of the pressing rod and slidably connected to the positioning hole, a guide slope on the surface of the positioning hole, and one end of the fixing bolt being a pointed tip.

[0006] Preferably, the surface of the machine body is provided with control buttons and a display screen, and the surface of the moving plate is provided with a fixing device. The grinding head is fixed to the surface of the moving plate by the fixing device.

[0007] Preferably, the surface of the extrusion rod is provided with a bending rod, and the other end of the bending rod relative to the extrusion rod is slidably connected to the groove.

[0008] Preferably, the bent rod has a connecting post in the middle and the connecting post is slidably connected to the slide groove.

[0009] Preferably, the groove is a vertical strip groove and the bottom center of the groove is aligned with the center of the positioning hole.

[0010] Preferably, the limiting frame includes a frame body, and the surface of the frame body is provided with a rotating groove.

[0011] Preferably, a folding rod is rotatably connected inside the rotating groove, and a baffle plate is provided at the connection between the frame and the folding rod.

[0012] Preferably, the thickness of the folding rod is less than the thickness of the frame, and a spring is provided inside the folding rod, with the spring connected to a rotating head on the surface of the folding rod.

[0013] Compared with related technologies, the device for testing the abrasion resistance of textiles provided by the present invention has the following advantages:

[0014] 1. This invention uses a limiting frame to compress the edge of the textile, ensuring that the textile is stably fixed on the surface of the fixing seat and preventing the textile edge from breaking and moving with the grinding head. At the same time, the fixing bolt fixes the position of the compression rod. The pointed tip on the surface of the fixing bolt and the guide slope on the surface of the positioning hole can ensure that the fixing bolt is connected to the positioning hole, which can facilitate the fixing of the fabric when testing thick fabric.

[0015] 2. This invention limits the rotation angle of the folding rod by using a baffle plate. The folding rod can easily pass through the grinding head while ensuring stable compression of the fabric, thus ensuring smooth testing. Attached Figure Description

[0023] Example 1, by Figure 1-6The present invention provides a device for testing the abrasion resistance of textiles, comprising a body 4, a transmission box 1 at the upper end of the body 4, a movable plate 7 connected to the side of the transmission box 1, a grinding head 6 fixed on the surface of the movable plate 7, a fixed seat 5 on the side of the body 4, a limit frame 8 sleeved on the upper end of the fixed seat 5, a sliding groove 10 and a positioning hole 12 on the side of the fixed seat 5, a pressing rod 9 slidably connected inside the sliding groove 10, a fixing bolt 11 slidably connected to the surface of the pressing rod 9 and slidably connected to the positioning hole 12, a guide slope on the surface of the positioning hole 12, and one end of the fixing bolt 11 being a pointed tip.

[0024] The fabric is placed on the surface of the fixed base 5, and the limiting frame 8 is pressed onto the fabric, squeezing the edge of the fabric onto the fixed base 5. Then, the squeezing rod 9 is pushed, and the squeezing rod 9 slides relative to the slide groove 10. The squeezing rod 9 then presses against the surface of the limiting frame 8, pushing the fixing bolt 11. The tip of the fixing bolt 11 and the guide slope on the surface of the positioning hole 12 cooperate with each other to make the fixing bolt 11 and the positioning hole 12 connected by threads. The squeezing rod 9 then presses down the limiting frame 8 to ensure that the fabric is stably fixed on the surface of the fixed base 5. The detection device is started by controlling the button 2, and the moving plate 7 drives the grinding head 6 to move linearly back and forth, thereby detecting the abrasion resistance of the textile.

[0025] In Embodiment 2, based on Embodiment 1, the limiting frame 8 includes a frame body 81, the surface of the frame body 81 is provided with a rotating groove 82, the interior of the rotating groove 82 is rotatably connected to a folding rod 83, and a blocking plate 84 is provided at the connection between the frame body 81 and the folding rod 83.

[0026] When installing and removing the limiting frame 8 on the surface of the fixed base 5, push the folding rod 83. The folding rod 83 rotates relative to the frame 81, and the limiting frame 8 passes through the grinding head 6. When the limiting frame 8 is stuck on the surface of the fixed base 5, due to the obstruction of the blocking plate 84, the folding rod 83 can only rotate inward towards the frame 81. Thus, the folding rod 83 can press the textile tightly, ensuring the smooth progress of the inspection.
