Description

Technical Field

[0001] The utility model relates to the technical field of textile yarns, in particular to a textile yarn strength detection device. Background Art

[0002] Yarn is a textile that is made of various textile fibers into products of a certain fineness. It is used for weaving, rope making, thread making, knitting and embroidery, etc. It is divided into short-staple yarn, continuous filament, etc. The texture and tensile strength of yarn used in different ways are different. Therefore, before using the yarn for corresponding product processing, the yarn to be used needs to be tested for strength. During the strength test, special yarn strength testing equipment will be used for testing.

[0003] To address this issue, Chinese patent number CN211426092U proposes a yarn strength testing device for textiles. This device fixes one end of the yarn to a winding drum and passes it through a wire groove, while the other end is fixed to a pull ring. A lifting motor drives the lifting bracket upward, thereby breaking the yarn. The strength of the yarn at breakage detected by the dynamometer is the yarn strength. This precise test greatly improves the reliability of yarn strength testing.

[0004] The above technical solution drives the lifting bracket to lift and lower through the lifting motor during yarn testing, and then pulls the yarn with both ends fixed to test its strength. During this process, the yarn needs to be tied into a knot when binding to prevent it from falling off midway. Once the yarn breaks, the staff needs to turn off the lifting motor immediately to prevent the lifting bracket from being driven to lift and lower by the motor all the time, causing damage to the structural parts. Therefore, the staff needs to pay attention to the yarn breakage at all times during yarn testing, which requires concentration and energy. In addition, the broken yarn also needs to be manually untied and cleaned from the connecting ring by the staff, which increases the workload of the staff and reduces the convenience of using the device. To this end, this design proposes a textile yarn strength detection device. Utility Model Content

[0005] In order to solve the above problems, the purpose of the present invention is to provide a textile yarn strength detection device to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model proposes a textile yarn strength testing device, comprising a testing platform, a tension mechanism and a connecting mechanism both mounted on the top of the testing platform;

[0009] In one example, a mounting platform is fixedly provided on the other side of the top of the detection platform, and a tensioner is installed on one side of the mounting platform.

[0010] In one example, the connection mechanism includes an arc-shaped connection ring installed at one end of the tensioner and the top of the movable base, and the outer walls of the two arc-shaped connection rings are both provided with sliding sleeves.

[0013] The textile yarn strength detection device proposed by the utility model can bring the following beneficial effects:

[0014] This textile yarn strength detection device uses an electric telescopic rod to push the yarn to pull the tensioner for strength detection. After the yarn breaks, the mobile base moves to the extrusion connecting plate so that the pressure ball squeezes the pressure sensor, and then the electric telescopic rod is closed and retracted to restore the mobile base to its original position.

[0021] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0022] The examples are as follows:

[0023] The utility model provides Figure 1-4 A textile yarn strength testing device shown includes a testing platform 1, a tension mechanism 2 and a connecting mechanism 5 both mounted on the top of the testing platform 1;

[0024] The tension mechanism 2 includes a first slide 201 provided on one side of the top of the detection platform 1, a movable base 202 is slidably provided on the inner wall of the first slide 201, a second slide 203 is provided on one end of both sides of the outer wall of the detection platform 1, and the outer walls of the two ends of the movable base 202 are respectively slidably connected with the inner walls of the two second slides 203, a receiving groove 204 is provided on one side of the inner wall of the first slide 201, a connecting plate 205 is rotatably provided on one side of the inner wall of the receiving groove 204, a pressure sensor 206 is installed on one side of the inner wall of the receiving groove 204, a pressure ball 207 is fixed on one side of the connecting plate 205, and the receiving groove A spring 208 is fixedly provided on one side of the inner wall of 204 at the outer edge of the pressure sensor 206, and one end of the spring 208 is fixedly connected to one side of the connecting plate 205, and the connecting plate 205 is squeezed by the movable base 202 and stored in the storage groove 204. When its outer wall is flush with the inner wall of the first slide groove 201, the pressure ball 207 fully squeezes the pressure sensor 206, and then the movable base 202 is contracted by the electric telescopic rod 209 and driven to move back to its original position. At this time, the connecting plate 205 is just flush with the inner wall of the first slide groove 201 and therefore does not affect the return sliding of the movable base 202.

[0025] An electric telescopic rod 209 is fixedly provided on one side of the inner wall of the first chute 201, and the output end of the electric telescopic rod 209 is fixedly connected to one side of the movable base 202. The electric telescopic rod 209 is electrically connected to the pressure sensor 206. When the pressure sensor 206 controls the electric telescopic rod 209 to close, the electric telescopic rod 209 automatically retracts after closing, and then moves the movable base 202 back to its original position, facilitating the detection of the next yarn.

[0026] Furthermore, a mounting platform 3 is fixed on the other side of the top of the testing platform 1, and a tensioner 4 is installed on one side of the mounting platform 3. The tensioner 4 is subjected to the tensile strength of the yarn when the yarn is pulled. When the yarn breaks, the tensile force applied to the tensioner 4 is the maximum tensile strength of the yarn.

[0027] Furthermore, the connecting mechanism 5 includes an arc-shaped connecting ring 501 installed at one end of the tensioner 4 and on the top of the movable base 202. The outer walls of the two arc-shaped connecting rings 501 are both provided with sliding sleeves 502. The sliding sleeves 502 are mounted on the arc-shaped connecting rings 501 and can slide at the same time, making it convenient for the sliding sleeves 502 to cut the yarn with the arc-shaped blade 503.

[0028] An arc-shaped blade 503 is fixed on one side of the inner wall of the two sliding sleeves 502, and an arc-shaped groove 504 is opened on both sides of the outer wall of the two arc-shaped connecting rings 501. The outer walls at both ends of the two arc-shaped sliding sleeves 502 are slidingly connected to the inner walls of the four arc-shaped grooves 504 respectively, and the arc-shaped grooves 504 limit the sliding sleeves 502 when they slide, so that they can slide stably on the arc-shaped connecting rings 501, and the cutting of the yarn is more effective and stable.

[0029] Working principle: When using the textile yarn strength detection device in this design, the two ends of the yarn are bound by two arc-shaped connecting rings 501, and then the electric telescopic rod 209 is started to push the mobile base 202 to slide in the first chute 201 and the second chute 203 and pull the yarn. At the same time, the yarn pulls the tensioner 4 so that the tension value it receives is displayed on the data display until the yarn breaks. At this time, it is the maximum tensile strength of the yarn, which can be displayed and recorded on the data display. After the mobile base 202 loses the resistance of the yarn, it continues to slide in the first chute 201 and squeezes the connecting plate 205 to squeeze it into the storage groove 204, and squeezes the pressure ball 207 on one side thereof. The force sensor 206 then issues a command to close and retract the electric telescopic rod 209, so that the pulling mechanism 2 no longer moves and the electric telescopic rod 209 moves back to its original position in the first slide groove 201 through the contraction of the electric telescopic rod 209, thereby avoiding continuous thrust on the inner wall of the first slide groove 201 and squeezing the side wall to cause structural damage. At the same time, there is no need for staff to always pay attention to the yarn breakage and control the extension and retraction of the electric telescopic rod 209. The yarn end remaining on the arc-shaped connecting ring 501 is cut off by the arc-shaped blade 503 on the inner wall through the sliding sleeve 502. The staff does not need to spend energy to untie the thread ends, which reduces the workload of the staff and improves the convenience of using the device.
