Description

Technical Field

[0001] The invention relates to the technical field of tension testing machines, in particular to a position-limiting and anti-slipping tension testing machine for textile processing. Background Art

[0002] Textile is a general term for spinning and weaving. In modern society, when textiles are being made, especially when innovations are being made, various testing equipment is generally used to detect the structural characteristics of new materials. For example, a tensile testing machine is used to detect the tensile strength that yarn or fabric spun from new materials can withstand.

[0003] The existing tensile testing machines for textile processing still have the following technical problems when in use, such as:

[0004] 1. The existing tensile testing machine is not convenient for quickly clamping the wire or fabric to be tested on the testing machine, thereby reducing efficiency;

[0005] 2. The existing tensile testing machine is not provided with a limited anti-drop structure, which makes the wire or fabric often fall out from the fixed position when the existing testing machine is testing the wire or fabric, thus making it impossible to continue the test;

[0006] Therefore, a limited anti-slip tension testing machine for textile processing is needed to solve the above problems. Summary of the invention

[0007] The object of the present invention is to provide a limited anti-slipping tensile testing machine for textile processing, so as to solve the problem in the above background technology that the existing tensile testing machine is not convenient for quickly clamping wires or fabrics and is not provided with a limited anti-slipping structure.

[0008] To achieve the above object, the present invention provides the following technical solutions:

[0009] A limit and anti-slip tension testing machine for textile processing comprises a support seat, a driving component and a clamping mechanism, a controller and a display screen are installed on the upper surface of the right end of the support seat, and two adjacent parallel vertical plates on the right end of the support seat form a whole through a support plate, so as to facilitate the installation of the driving component, a horizontally arranged limit rod is fixedly connected between the vertical plate at the left end of the support seat and the middle vertical plate, and one end of the screw rod is connected to a bearing on the vertical plate at the left end of the support seat, and the other end of the screw rod is connected to the driving component through the bearing passing through the middle vertical plate, and the screw rod is also threaded through the lower end angle of the displacement triangle plate, and the other angle of the lower end of the displacement triangle plate is movably penetrated by the limit rod, the displacement triangle plate is connected with a clamping mechanism through a tension sensor, and a clamping mechanism is also arranged on the side of the vertical plate at the left end of the support seat facing the displacement triangle plate.

[0010] Furthermore, the driving component includes a servo motor, a belt transmission mechanism, a worm and a worm gear. The servo motor is installed between two adjacent parallel vertical plates at the right end of the support seat, and the shaft end of the servo motor is connected to the worm through the belt transmission mechanism. The worm bearing is connected to the support plate, and the worm is connected to the worm gear, and the worm gear is coaxially keyed to the end of the screw.

[0011] By adopting the above technical solution, the operation of the servo motor can drive the belt transmission mechanism to rotate, thereby driving the worm to rotate. Through the rotation of the worm, the worm wheel drives the lead screw to rotate, thereby achieving the purpose of driving the displacement triangle plate to move.

[0012] Furthermore, the belt transmission mechanism is a reduction transmission structure.

[0013] By adopting the above technical scheme, the rotation speed of the worm can be greatly reduced through the deceleration belt transmission mechanism. Since the worm gear mechanism composed of the worm and the worm wheel not only has the characteristics of labor saving but also has the characteristics of deceleration, the purpose of reducing the rotation speed of the screw can be further reduced. By reducing the rotation speed of the screw, the textile thread or fabric can be prevented from being quickly torn apart, thereby improving the accuracy of detection and enhancing the accuracy of detection.

[0014] Furthermore, the servo motor and the tension sensor are both electrically connected to the controller and the display screen, so that the start and stop of the servo motor can be controlled by the controller and the display screen, and the data of the tension sensor can be transmitted to the controller and the display screen.

[0015] By adopting the above technical solution, the operation of the servo motor can be easily controlled through the controller and the display screen, and the servo motor can be controlled to stop running by receiving data transmitted by the tension sensor, so that the servo motor can be stopped in time at the moment when the textile thread or fabric is broken.

[0016] Furthermore, the displacement triangle plate is an equiangular triangle, and the clamping mechanism connected to the displacement triangle plate is arranged at the upper angle of the triangle.

[0017] The above technical solution can improve the stability of the textile thread or fabric when it is pulled, ensure that the textile thread or fabric is subjected to stable force, and avoid inaccurate experimental data caused by excessive instantaneous pulling force.

[0018] Furthermore, the clamping mechanism includes a compression spring, a convex block, a rotating disk, a mounting disk, a clamping disk, a locking strip, a coupling rod, a piston plate, an air hole, an air bag, a clamping through hole, a limiting groove, an air pipe and a locking groove. The convex block is arranged on the support seat and the displacement triangle plate, and each convex block is connected to the rotating disk through a compression spring. The two rotating disks are respectively connected to the support seat and the tension sensor by bearings, and a locking strip coaxial with the rotating disk is arranged on the rotating disk. The locking strip is engaged and connected in the locking groove, and the locking groove is arranged On the mounting plate, there are two mounting plates, and the mounting plate is a 1 / 2 disc, one end of the coupling rod is fixedly connected to the mounting plate, and a piston plate is fixedly installed on the other end of the coupling rod, the piston plate extends into the corresponding air hole, and the air hole is arranged on the clamping side of the clamping plate, the clamping side of the clamping plate is provided with a limiting groove, and the clamping plate is also provided with a clamping through hole, and the clamping through hole is connected with the limiting groove, an air bag is arranged in the clamping through hole, and the air bag is connected through the air pipe and the air hole.

[0019] By adopting the above technical solution, the end of the textile thread or cloth is knotted and then put between the two limit grooves, so that the textile thread or cloth can be clamped between the two clamping mechanisms, and in this process, the textile thread or cloth will be clamped between the two airbags, and the friction force will prevent the textile thread or cloth from falling under the action of gravity. When the driving component is operated, the textile thread or cloth is pulled, and in this process, the mounting plate and the clamping plate will move away from each other. The piston plate moves in the air hole, and the gas in the air hole can be squeezed into the airbag, causing the two airbags to expand, thereby increasing the squeezing of the textile thread or cloth, and the textile pulling force is too large, causing the textile thread or cloth to fall off.

[0020] Furthermore, the air hole has a convex structure, and its smaller inner diameter is provided with an outer side of a rubber sealing film, and the inner side of the rubber sealing film is connected to the outer side of the coupling rod, so as to achieve the purpose of sealing the air hole opening.

[0021] By adopting the above technical solution, when the coupling rod moves, the piston plate can squeeze the gas in the air hole into the air bag instead of directly discharging it from the outer end opening of the air hole.

[0022] Furthermore, the structural shape of the limiting groove is a partial funnel shape, and the minimum diameter of the limiting groove is smaller than the inner diameter of the clamping through hole.

[0023] By adopting the above technical solution, after the end of the textile thread or cloth is knotted, it can be directly clamped in the limiting groove, thereby achieving the clamping of the textile thread or cloth.

[0024] Furthermore, the distance between the position where the air pipe is connected to the air hole and the clamping side of the clamping disk is smaller than the distance between the piston plate and the clamping side of the clamping disk in a natural state.

[0025] By adopting the above technical solution, it is possible to easily squeeze the gas in the air hole into the air bag when the piston plate moves in the air hole.

[0026] Furthermore, the clamping disk is partially cylindrical, and the angle of the clamping disk is less than 180°.

[0027] By adopting the technical solution, a slot can be reserved to facilitate the pulling of textile thread or cloth into the clamping through hole.

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows: the position-limited anti-slipping tension detection machine for textile processing can realize the smooth pulling of textile thread or fabric, thereby ensuring the accuracy of experimental data, avoiding the problem of excessive instantaneous pulling force causing large error in experimental data, and facilitating the rapid clamping of textile thread or fabric, and limiting the thread or fabric during the pulling process to prevent the end thereof from slipping out, thereby ensuring the stability of the detection process, and facilitating the cleaning of the thread or fabric on the machine:

[0029] 1. The belt transmission mechanism in the form of deceleration can reduce the speed of the screw, which can facilitate the slowing down of the speed of the displacement triangle plate. The worm gear mechanism composed of the worm and the worm wheel can further reduce the speed of the screw, so that the displacement triangle plate can move smoothly at a low speed, so that the pulled line or fabric is evenly stressed, avoiding excessive instantaneous tension and causing inaccurate test results.

[0030] 2. Through the local funnel-shaped limiting groove and the angles of the two clamping plates are less than 180°, the two clamping plates form an overall retention gap, which is convenient for clamping the knotted wire or cloth in the limiting groove and passing through the clamping through hole, so that the wire or cloth can be clamped quickly. In addition, when pulling the wire or cloth, the installation plate and the clamping plate can be moved away from each other, so that the coupling rod drives the piston plate to move in the air hole, and then the gas in the air hole is squeezed into the air bag, so that the air bag expands. The expansion of the air bag will increase the squeezing of the wire or cloth, so that the wire or cloth is limited, thereby preventing the wire or cloth from escaping from the clamping through hole;

[0031] 3. By rotating the mounting plate, the lock bar on the mounting plate can be disengaged from the lock groove, and the mounting plate and the clamping plate can be separated. At this time, the two clamping plates can be disengaged to facilitate the cleaning of the wire or fabric between the two, so as to avoid residual wire or fabric fluff between the two, which may affect subsequent detection.

[0043] Embodiment 1:

[0044] In order to solve the problem that the previous tensile testing machine cannot pull the wire or fabric steadily, the following technical solution is now provided. Specifically,

In this process, the belt transmission mechanism 4 is a reduction structure, and the worm gear structure composed of the worm wheel 11 and the worm 5 is also a reduction structure, so the rotation speed of the screw 8 can be greatly reduced, so that it is convenient to pull the line or cloth smoothly and avoid excessive instantaneous pulling force.

[0046] Embodiment 2:

[0047] In order to solve the problem that yarn or fabric is easy to fall out when the tensile testing machine is used to test yarn or fabric, specifically,

[0048] A clamping mechanism is connected to the displacement triangle plate 7 through a tension sensor 25, and a clamping mechanism is also provided on the side of the vertical plate at the left end of the support seat 1 facing the displacement triangle plate 7. The clamping mechanism includes a compression spring 10, a protrusion 12, a rotating disk 13, a mounting disk 14, a clamping disk 15, a locking strip 16, a coupling rod 17, a piston plate 18, an air hole 19, an air bag 20, a clamping through hole 21, a limiting groove 22, an air pipe 23 and a locking groove 24. The protrusion 12 is provided on the support seat 1 and the displacement triangle plate 7, and each protrusion 12 is connected to the rotating disk 13 through a compression spring 10. The two rotating disks 13 are respectively connected to the support seat 1 and the tension sensor 25 by bearings, and a locking strip 16 coaxial with the rotating disk 13 is provided on the rotating disk 13, and the locking strip 16 is engaged and connected to the locking groove 24, and the lock groove 24 is arranged on the mounting plate 14, the mounting plate 14 is provided with two, and the mounting plate 14 is a 1 / 2 disc, one end of the coupling rod 17 is fixedly connected to the mounting plate 14, and the other end of the coupling rod 17 is fixedly installed with a piston sheet 18, the piston sheet 18 extends into the corresponding air hole 19, and the air hole 19 is arranged on the clamping side of the clamping plate 15, and the clamping side of the clamping plate 15 is provided with a limiting groove 22, and the clamping plate 15 is also provided with a clamping through hole 21, and the clamping through hole 21 is connected with the limiting groove 22, an air bag 20 is arranged in the clamping through hole 21, and the air bag 20 is connected with the air hole 19 through the air pipe 23, the structural shape of the air hole 19 is convex, and its smaller inner diameter is provided with the outer side of the rubber sealing film, and the inner part of the rubber sealing mold The side is connected to the outer side of the coupling rod 17 to achieve the purpose of sealing the opening of the air hole 19. The structural shape of the limiting groove 22 is partially funnel-shaped, and the minimum diameter of the limiting groove 22 is smaller than the inner diameter of the clamping through hole 21. The distance between the position where the air pipe 23 connects to the air hole 19 and the clamping side of the clamping disk 15 is smaller than the distance between the piston plate 18 and the clamping side of the clamping disk 15 in the natural state. The clamping disk 15 is partially columnar, and the angle of the clamping disk 15 is less than 180°. When in use, the end of the line or cloth is knotted, and then passed through two clamping disks 15 with an angle less than 180°, so that the line or cloth comes into the clamping through hole 21 and the limiting groove 22.

At this time, the two clamping disks 15 can be completely separated. After that, the remaining wire or fabric fragments between the two clamping disks 15 can be cleaned to avoid affecting subsequent testing.
