Description

Technical Field

[0001] This invention relates to the field of yarn tube paper technology, and more specifically, to a performance testing device suitable for yarn tube paper. Background Technology

[0002] Yarn tube paper is an industrial paper specifically used in the textile and chemical fiber industries for winding yarns, filaments, and other materials into paper cores. It features high strength, high stiffness, and good moisture resistance, ensuring shape stability and resistance to deformation during high-speed winding and unwinding. Yarn tube paper is typically made from multiple layers of kraft pulp or recycled pulp through a special pressing process, resulting in a smooth surface and neat edges. Different thicknesses and sizes can be customized to meet specific needs, making it an indispensable basic material in textile production.

[0003] After the yarn tube paper is processed, its strength needs to be tested. Since yarn tube paper is mostly stored in rolls, the sampled yarn tube paper to be tested is prone to bending and wrinkles. These factors will destroy the uniformity of the paper structure, thus leading to distorted test results.

[0004] For example, the strength testing device and method for producing high-strength yarn tube paper, disclosed in CN116929903B, can first stretch and flatten the wrinkles of the yarn tube paper before conducting the strength test. However, after the complex stretching and flattening process, the aforementioned patent can only perform a single test. For each subsequent test, workers still need to perform the feeding operation. Since the strength test of yarn tube paper usually requires multiple tests, this necessitates repeated complex operations by workers, severely impacting testing efficiency. Summary of the Invention

[0021] Reference Figures 1 to 8 In one embodiment of this application, a performance testing device suitable for yarn tube paper includes a base 1, a conveying assembly, and a stretching mechanism; Multiple rollers 2 are rotatably connected to the base 1. A side plate 3 is fixedly connected to the base 1. A top plate 4 is fixedly connected to the side plate 3. A first electric cylinder 5 is disposed below the top plate 4. A first thrust sensor 6 is fixedly connected to the piston rod of the first electric cylinder 5. A test head 7 is fixedly connected to the end of the first thrust sensor 6 away from the first electric cylinder 5. Figure 2 and Figure 8 The first electric cylinder 5 can push the test head 7 downward, causing the test head 7 to puncture the yarn tube paper, and the first thrust sensor 6 monitors the downward thrust value of the first electric cylinder 5, thereby detecting the strength of the yarn tube paper; The conveying assembly is connected to a plurality of idler rollers 2, and the conveying assembly is used to drive the plurality of idler rollers 2 to rotate.

Multiple sliders 10 are fixedly connected to each base 9. The multiple sliders 10 are slidably connected to multiple slide rails 8 respectively.

A horizontal bar 13 is fixedly connected to one end of each horizontal plate 12. like Figure 4 Two slide rails 8 support two bases 9 via multiple sliders 10, allowing the two bases 9 to move laterally along the slide rails 8; for example Figure 5 The upper and lower horizontal plates 12 can slide vertically along the first guide rod 11 respectively, and the two horizontal plates 12 respectively drive the horizontal rod 13 on them to move vertically. like Figure 1 and Figure 4During feeding, a certain length of yarn tube paper is placed on two idler rollers 2, and the yarn tube paper is located between two crossbars 13 on each base 9; Each of the bases 9 is provided with a clamping assembly, which is used to drive the two crossbars 13 on the base 9 to move in opposite directions; The lateral movement component is connected to the two bases 9, and the lateral movement component is used to drive the two bases 9 to move in opposite directions; like Figure 1 and Figure 4 In the initial state, the upper and lower crossbars 13 on the base 9 are separated from each other, while the two crossbars 13 at the same height are in contact with each other. First, the clamping components on each base 9 drive the two crossbars 13 on the base 9 to move closer to each other, and the upper and lower crossbars 13 can apply a certain clamping force to the yarn tube paper (not completely clamped). Then, the transverse component drives the two bases 9 to move in opposite directions along the slide rail 8, and the two pairs of crossbars 13 on the two bases 9 can stretch the yarn tube paper in opposite directions, thereby stretching and flattening the yarn tube paper. Finally, the test head 7 punctures the yarn tube paper to complete the test. like Figure 1 and Figure 3 After the test is completed, all the crossbars 13 are reset to their initial positions. At this time, the yarn tube paper is supported by two rollers 2. The two rollers 2 are driven to rotate by the conveying component, and the two rollers 2 can move the yarn tube paper, thereby adjusting the position of the yarn tube paper so that the test head 7 can perform strength test again.

[0024] In a preferred embodiment of this application, the transverse movement assembly includes a second bidirectional lead screw 18, a second motor 19, and a transmission plate 20.

The bridge plate 27 can then push the upper ring block 26 downward by multiple second guide rods 25, so that the upper ring block 26 and the lower ring block 24 clamp the yarn tube paper. The test head 7 is located on the axis of the upper ring block 26 and the lower ring block 24, so that the test head 7 can test the clamped yarn tube paper and obtain more accurate test results. A thrust sensor is installed between the piston rod of the third electric cylinder 28 and the bridge plate 27 to monitor the clamping force of the upper ring block 26 and the lower ring block 24 on the yarn tube paper.

[0026] In a preferred embodiment of this application, the first electric cylinder 5 is mounted on the bridge plate 27, such as... Figure 8 During the descent of the bridge plate 27, the first electric cylinder 5 is simultaneously lowered.

[0028] In a preferred embodiment of this application, pressure rollers 32 are respectively provided above the two idler rollers 2, and each pressure roller 32 is rotatably connected to a roller frame 33.

[0030] Working principle: First, the clamping components on each base 9 drive the two crossbars 13 on the base 9 to move closer to each other. The two crossbars 13 can then apply a certain clamping force to the yarn tube paper. Then, the transverse component drives the two bases 9 to move in opposite directions along the slide rail 8. The two pairs of crossbars 13 on the two bases 9 can then stretch the yarn tube paper in opposite directions, thereby stretching and flattening the yarn tube paper. Finally, the test head 7 punctures the yarn tube paper to complete the test. After the test is completed, all the crossbars 13 are reset to their initial positions. At this time, the yarn tube paper is supported by two rollers 2. The two rollers 2 are driven to rotate by the conveying component, and the two rollers 2 can move the yarn tube paper, thereby adjusting the position of the yarn tube paper so that the test head 7 can perform strength test again. This allows multiple yarn tube paper tests to be completed without manual intervention, effectively improving the strength test efficiency of the yarn tube paper.
