Description

Technical Field

[0001] This application relates to the field of fabric tearing instrument technology, and more specifically to a fabric clamping structure for a fabric tearing instrument. Background Technology

[0002] The tear resistance of a fabric is one of the important indicators for testing the structural strength of a fabric. A fabric tear tester is an instrument used to measure the tear resistance of various woven fabrics.

[0003] There is a fabric tearing device, such as Figure 1 and Figure 2 As shown, the device includes a base 90, a testing component 91, a cutting blade 92, a blocking member 93, and two spaced-apart clamping components 94. The testing component 91 includes a fan-shaped pendulum 911, a pointer 912, and several weights 913. The center of the fan-shaped pendulum 911 is rotatably mounted on the base 90, and the weights 913 are mounted on the fan-shaped pendulum 911. The cutting blade 92 is located between the two clamping components 94 and is slidably disposed on the base 90. The blocking member 93 is movably mounted on the base 90. One clamping component 94 is connected to the fan-shaped pendulum 911, and the other clamping component 94 is connected to the base 90. It should be noted that during the test, the fabric 95 to be tested is clamped by the two clamping components 94. Then, the cutting blade 92 is slid and a cut is made at the bottom of the fabric 95. After calibrating the pointer 912 and the scale position of the fan-shaped pendulum 911, the blocking member 93 is opened. The fan-shaped pendulum 911 then rotates at a predetermined angle under the action of gravity. Since one of the clamping components 94 is fixedly connected to the fan-shaped pendulum 911 and rotates with the fan-shaped pendulum 911, the fabric 95 to be tested is torn. At the same time, the pointer 912 will point to the corresponding scale of the fan-shaped pendulum 911 to read the tear resistance of the fabric. However, the existing clamping component 94 has a fixed height and only clamps the bottom of the fabric 95 to be tested. This results in the upper part of the fabric either hanging down or folded over when placed. When the fan-shaped pendant 911 rotates and tears the fabric 95 to be tested, the tear in the clamped area is relatively straight between the two clamping components 94. The upper part of the tear is not restricted and may tilt to one side, affecting the accuracy of the measured data and making it difficult to meet the requirements of high-precision measurement.

[0004] Therefore, there is a need for a fabric clamping structure for a fabric tearing tester that allows for selectable clamping component height, effectively prevents the upper part of the fabric under test from sagging, and helps reduce the risk of the upper part of the tear tilting. Summary of the Invention

[0005] The main objective of this application is to provide a fabric clamping structure for a fabric tearing tester, comprising a base, a testing component, a cutting blade, a blocking member, and two spaced-apart clamping components. The testing component includes a fan-shaped pendulum and several weights. The center of the fan-shaped pendulum is rotatably mounted on the base, and the weights are mounted on the fan-shaped pendulum.

The fixed seat on one of the clamping components is fixedly connected to the fan-shaped ornament, and the fixed seat on the other clamping component is fixedly connected to the seat body. By setting the lifting seat, the tester can test the tear strength curve of the fabric when there are restrictions at both ends under the long tear. It has the advantages of selectable clamping component height, effectively avoiding the upper part of the fabric under test from drooping, and helping to reduce the risk of the upper part of the tear tilting.

[0029] Schematic diagram of fabric clamping structure for a fabric ripping machine, for reference. Figures 3 to 7 According to a preferred embodiment of the present invention, a fabric clamping structure for a fabric tearing device is provided, such as... Figure 3 As shown, the device includes a base 80, a testing component 81, a cutting blade 82, a blocking member 83, and two spaced-apart clamping components 10. The testing component 81 includes a fan-shaped pendulum 811, a pointer, and several weights (not shown in the figure). The center of the fan-shaped pendulum 811 is rotatably mounted on the base 80, and the weights are mounted on the fan-shaped pendulum 811. The cutting blade 82 is located between the two clamping components 10 and is slidably disposed on the base 80. The blocking member 83 is movably mounted on the base 80. One clamping component 10 is connected to the fan-shaped pendulum 811, and the other clamping component 10 is connected to the base 80.

[0030] It should be noted that during the test, the fabric to be tested is clamped by the two clamping components 10. Then, the cutting blade 82 is slid to cut a slit at the bottom of the fabric. After calibrating the pointer and the scale position of the fan-shaped pendulum 811, the blocking member 83 is opened. The fan-shaped pendulum 811 then rotates at a predetermined angle under the action of gravity. Since one of the clamping components 10 is fixedly connected to the fan-shaped pendulum 811 and rotates with it, the fabric to be tested is torn. At the same time, the pointer will point to the corresponding scale of the fan-shaped pendulum 811 to read the tear resistance of the fabric. Since the above structure is all prior art, it will not be described in detail here. The further structure of the testing component 81 is disclosed in the patent document (CN219532704U).

[0031] Furthermore, such as Figure 3 As shown, each clamping assembly 10 includes a fixed base 101 and a sliding base 102. Each sliding base 102 is slidably disposed on the corresponding fixed base 101. Specifically, each clamping assembly 10 also includes a first lead screw 103, which is rotatably mounted on the fixed base 101 and is helically connected to the sliding base 102. When the first lead screw 103 rotates circumferentially, the sliding base 102 moves closer to or further away from the fixed base 101. It should also be noted that, to improve self-locking, the first lead screw 103 has a trapezoidal thread. Furthermore, the fixed base 101 on one clamping assembly 10 is fixedly connected to the fan-shaped swing member 811 and rotates with the fan-shaped swing, while the fixed base 101 on another clamping assembly 10 is connected to the seat body 80, which is normally fixed.

[0032] Since the height of the sliding seat 102 is fixed, when the sliding seat 102 moves towards the fixed seat 101 and clamps the fabric to be tested, it can only clamp the lower half of the fabric. When the tester needs to know the tear strength curve of the fabric over a longer length, the upper half of the fabric is unrestricted, causing the tear to deviate at a large angle when it extends to the upper half of the fabric, thus affecting the tear strength curve of the fabric. For example, if the pant leg is tubular after molding, the fabric will be restricted by the tubular fabric on both sides of the tear when it is torn. Its tear strength curve is still somewhat different from that of a flat piece with no restriction on both sides of the tear.

[0033] Therefore, in the embodiments of this application, such as Figure 3 and Figure 4As shown, each of the clamping components 10 further includes a riser 104, which is located above the sliding seat 102 and is detachably connected to the sliding seat 102. The highest point of the fixed seat 101 is higher than or level with the highest point of the riser 104 when it is installed on the sliding seat 102.

[0034] It should be noted that by providing an extender seat 104 that can be detachably connected to the sliding seat 102, when the sliding seat 102 presses the lower half of the fabric to be tested onto the fixed seat 101, the extender seat 104 simultaneously presses the upper half of the fabric to be tested onto the fixed seat 101. This effectively prevents the upper half of the fabric from sagging and helps reduce the risk of the upper half of the tear tilting. When testers need to test the tear strength curve of fabric under restricted conditions over a longer length, they can install the extender seat 104 on the sliding seat 102 and compare it with the tear strength curve of fabric under unrestricted conditions without the extender seat 104 installed. This provides a more comprehensive understanding of the fabric's tear resistance. Compared to existing technologies, this method offers advantages such as selectable clamping component height and more comprehensive test data.

[0035] Furthermore, to test the tear strength curve of the fabric when there is a restraint at the end away from the tear, such as... Figure 3 and Figure 5 As shown, the fabric clamping structure of the fabric tearing instrument also includes an anti-sagging clamping component 20. The anti-sagging clamping component 20 includes a mounting base 201, a stop block 202 and a pressing block 203. The mounting base 201 is located above the two clamping components 10, and the stop block 202 is detachably connected to the mounting base 201. The pressing block 203 is slidably disposed on the mounting base 201.

[0036] It should be noted that during testing, the top of the fabric to be tested is placed between the abutment block 202 and the pressing block 203, and the pressing block 203 presses the top of the fabric to be tested against the abutment block 202. It should also be pointed out that the anti-sagging clamping assembly 20 is further positioned above a clamping assembly 10 fixedly connected to the base 80, and the anti-sagging clamping assembly 20 does not interfere with the movement of the fan-shaped swing member 811.

[0037] Furthermore, to enable the clamping block 203 to slide on the mounting base 201, as follows: Figure 5As shown, the anti-sagging clamping assembly 20 further includes an elastic element 204. The end of the clamping block 203 facing away from the abutment block 202 has an extension rod 205. One end of the mounting base 201 has a first bent section 2011. The extension rod 205 is slidably passed through the first bent section 2011 and extends out a predetermined length. The two ends of the elastic element 204 are respectively connected to the clamping block 203 and the first bent section 2011.

[0038] It should be noted that, under the elastic force of the elastic element 204, the pressing block 203 normally abuts against the abutting block 202. When the top of the fabric to be tested is placed, the tester pulls the extension rod 205 and extends the top of the fabric to be tested between the pressing block 203 and the abutting block 202.

[0039] Furthermore, to achieve pre-fixation of the heightening seat 104 and the sliding seat 102, such as... Figure 4 As shown, the top of the sliding seat 102 has two first insertion holes 1021, and the bottom of the raising seat 104 has two first insertion posts 1041, with the two first insertion posts 1041 respectively inserted into the two first insertion holes 1021.

[0040] In addition, to improve the connection strength between the heightening seat 104 and the sliding seat 102, such as Figure 4 As shown, a magnet 10211 is embedded in the bottom wall of each of the first insertion holes 1021. When the first insertion post 1041 is inserted into the corresponding first insertion hole 1021, the first insertion post 1041 and the magnet 10211 are attracted together.

[0041] However, since the diameter of the first insertion hole 1021 and the first insertion post 1041 are in clearance fit, the riser 104 can still move slightly relative to the sliding seat 102, which means that when the sliding seat 102 presses the fabric to be tested, the riser 104 may not fully press the fabric to be tested.

[0042] In view of this, such as Figure 3 , Figure 6 and Figure 7 As shown, each of the clamping components 10 further includes a fastening component 105, which includes a first socket 1051 and a second socket 1052. The second socket 1052 is slidably disposed on the first socket 1051, as shown. Figure 4As shown, both sides of the sliding seat 102 and the raising seat 104 have a groove 1021, and the bottom wall of each groove 1021 has a second insertion hole 1022. The opposite ends of the first socket 1051 and the second socket 1052 each have a second bent section 10511, and the opposite ends of the two second bent sections 10511 each have a second insertion post 10512. The two second bent sections 10511 extend into the corresponding grooves 1021 of the sliding seat 102 and the raising seat 104, and each second insertion post 10512 is inserted into or disengaged from the corresponding second insertion hole 1022.

[0043] It should be noted that after the two first plugs 1041 are respectively inserted into the two first sockets 1021, the tester can first move the second socket 1052 away from the first socket 1051 until the distance between the two second plugs 10512 is equal to or greater than the width of the riser 104 and the sliding seat 102, so that the tester can extend the two second bent sections 10511 into the corresponding grooves 1021 of the sliding seat 102 and the riser 104, and make the second plugs 10512 face the second socket 1022. Then, the tester can first insert the two second plugs 10512 on the first socket 1051 into the corresponding second socket 1022, and then move the second socket 1052 towards the first socket 1051 until the two second plugs 10512 on the second socket 1052 are also inserted into the corresponding second socket 1022 and abut against the bottom wall of the second socket 1022. Due to the clamping force of the fastening component 105, the riser 104 can be effectively prevented from moving slightly relative to the sliding seat 102.

[0044] Furthermore, to enable the second socket 1052 to slide on the first socket 1051, as follows: Figure 6 and Figure 7 As shown, the fastening assembly 105 further includes a second lead screw 1053, which is rotatably mounted on the first socket 1051 and is helically connected to the second socket 1052. The second socket 1052 has a clearance groove 10521 on the side near the second lead screw 1053. It should be noted that the clearance groove 10521 is provided to facilitate the screwing of the second lead screw 1053.

[0045] Additionally, in the embodiments of this application, such as Figure 4As shown, the second insertion hole 1022 located on the sliding seat 102 is arranged perpendicularly to the corresponding first insertion hole 1021 and communicates with each other. That is, when the fastening assembly 105 is fastened, the second insertion post 10512 extending into the second insertion hole 1022 on the sliding seat 102 will also apply a pre-tightening force to the first insertion post 1041 to prevent it from moving.

[0046] In summary, the fabric clamping structure of the fabric tearing tester described in the embodiments of this application is explained, which provides advantages such as selectable clamping component height, effective prevention of the upper part of the fabric to be tested from sagging, and help to reduce the risk of the upper part of the tear tilting.

[0047] It is worth mentioning that, in this embodiment, the fabric clamping structure of the fabric ripping machine is simple in structure, does not involve complex manufacturing processes or expensive materials, and is highly economical. At the same time, for manufacturers, the fabric clamping structure of the fabric ripping machine provided in this application is easy to produce and inexpensive, which is more conducive to controlling production costs and further facilitates product promotion and use.

The purpose of the present invention has been fully and effectively achieved.
