AI Technical Summary
When handling slippery woven elastic fabrics, the clamping mechanism of traditional tensile strength testers experiences reduced friction, leading to unstable clamping and potential slippage, which affects normal tensile testing.
A worm gear mechanism is used to drive the rotating clamping rollers and triangular blocks. Stable clamping is achieved through the contact between multiple triangular blocks and the woven elastic fabric. The squeezing action of the rotating clamping rollers and triangular blocks fixes the fabric in the clamping groove, thereby enhancing the clamping force.
This improves the stability of woven elastic fabrics in tensile testing, prevents slippage, and ensures the accuracy and reliability of the test.

Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of applying stable tension or pressure, particularly relates to a stretching device for production of woven stretch cloth. BACKGROUND
[0002] In the textile industry, especially in the production and quality detection process of woven stretch cloth, the tensile strength testing device is an indispensable key equipment, which is mainly used for measuring the strength and elongation rate of fabric under external force, and is crucial for evaluating the durability, elastic recovery ability and optimization of weaving process of the fabric, however, with the continuous progress of textile technology and the increasing diversification of consumer demand, more and more woven stretch cloths with special surface properties or functions appear in the market, including those with smooth surface, large elasticity and difficult to effectively clamp.
[0003] The clamping mechanism of the traditional tensile strength tester is usually designed as a simple mechanical clamping or pneumatic clamping mode, which relies on the friction between the two clamping blocks and the woven stretch cloth to maintain stability during the test. This clamping block design can usually meet the tensile test requirements when processing ordinary woven stretch cloth, but when facing relatively smooth woven stretch cloth, the friction between the clamping blocks and the woven stretch cloth will be relatively reduced, which may cause the woven stretch cloth to be not stable enough during the tensile test, and thus may cause slipping problem, thereby affecting the normal tensile test of the woven stretch cloth. SUMMARY
[0004] The utility model aims at least solves one of the technical problems existing in the prior art, and provides a stretching device for production of woven stretch cloth, which can solve the problem that the clamping block design can usually meet the tensile test requirements when processing ordinary woven stretch cloth, but when facing relatively smooth woven stretch cloth, the friction between the clamping blocks and the woven stretch cloth will be relatively reduced, which may cause the woven stretch cloth to be not stable enough during the tensile test, and thus may cause slipping problem, thereby affecting the normal tensile test of the woven stretch cloth.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a stretching device for producing woven elastic fabric, comprising an operating table, with two support frames fixedly connected to the top of the operating table. A display control screen is provided at one end of the support frame near the right side. Lifting grooves are provided at opposite ends of the two support frames. Lifting plates are slidably connected inside the two lifting grooves. A tension sensor is fixedly installed at the bottom end of the lifting plate. The tension sensor is electrically connected to the display control screen. Clamping assemblies are fixedly installed at the bottom end of the tension sensor and at the top end of the operating table. The clamping assembly includes a fixing block. The bottom end of the fixing block is fixedly connected to the top end of the operating table. A clamping groove is provided inside the fixing block. A rotating clamping roller is rotatably connected inside the clamping groove. Multiple triangular pointed blocks are fixedly connected to the outer surface of the rotating clamping roller. An anti-slip layer is fixedly connected to the inner wall of the clamping groove.
[0006] Preferably, the fixed block has a groove inside, one end of the rotating clamping roller rotates through the inside of the groove, and one end of the rotating clamping roller rotates through the inside of the groove and is fixedly connected to a worm gear.
[0007] Preferably, a worm gear is rotatably connected inside the groove, and the outer surface of the worm gear meshes with the outer surface of the worm wheel.
[0008] Preferably, a rotating groove is provided on one side of the fixed block, and one end of the worm gear is rotatably connected to the inner wall of the rotating groove.
[0009] Preferably, one end of the worm gear is fixedly connected to a rotating handle, and there are two clamping assemblies, which are fixed relative to each other at the top of the operating table and the bottom of the tension sensor.
[0010] Preferably, both of the lifting slots are rotatably connected to threaded rods, and the outer surfaces of the two threaded rods are threadedly engaged with the two sides of the lifting plate.
[0011] Preferably, a drive motor is fixedly connected to the top of the support frame on the left, and the output end of the drive motor rotates through the interior of the lifting groove and is fixedly connected to the top of the corresponding threaded rod.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This stretching device for producing woven elastic fabric uses a worm gear to drive a rotating clamping roller, causing multiple triangular blocks to rotate. These triangular blocks then cause one end of the woven elastic fabric to be rolled and squeezed, thus fixing the woven elastic fabric inside the clamping groove. This not only facilitates the fixing of the woven elastic fabric, but also, due to the influence of the rotating clamping roller and the multiple triangular blocks, strengthens the fixing force of one end of the woven elastic fabric inside the clamping groove, making the clamping of the woven elastic fabric more stable. Therefore, during the stretching test of the woven elastic fabric, it is less likely to slip off, thus improving the usability of the stretching device. Attached Figure Description
