Description

Technical Field

[0001] This utility model belongs to the field of fabric testing technology, and in particular relates to a device for testing the elasticity of elastic fabrics used in textile production. Background Technology

[0002] Elastic fabric is a type of fabric incorporating elastic fibers (such as spandex) during the weaving process. In daily life and industrial production, elastic fabric allows clothing to stretch freely, greatly improving the comfort of movement. In the field of medical supplies, bandages and protective gear are also often made from elastic fabric, using its elasticity to fix and support body parts, aiding in recovery. During production, elastic fabric needs to undergo elasticity testing, as elasticity is its core performance indicator. If the elasticity is insufficient, it cannot meet the stretch requirements of clothing and medical supplies; while excessive or unstable elasticity will cause product deformation and dimensional instability, seriously affecting its use.

[0003] For example, Chinese patent application CN220104710U discloses a fabric tensile and elasticity testing device, including a platform with a groove penetrating the center of the top of the platform. Fixing plates are fixedly connected to both sides of the platform. A first motor is fixedly connected to the center of the top right side of the right fixing plate, with a first threaded rod penetrating and fixedly connected to its output end. A second motor is fixedly connected to the center of the right side of the right fixing plate, with a second threaded rod penetrating and fixedly connected to its output end. Sliding grooves are provided at both the front and rear ends of the platform's bottom. In this invention, two first clamping blocks move to the left and right to straighten the fabric. A secondary hydraulic cylinder is activated and extends upward to lift the fabric, thereby testing the fabric's tensile strength and elasticity. The tensile strength and elasticity of the fabric can be obtained by injecting hydraulic oil into the secondary hydraulic cylinder, resulting in better performance and greater ease of use.

[0004] In actual use, fabrics are subjected to both tensile forces and point pressure. Both of these forces can cause the fabric to deform. However, the above method can only test the tensile force on the fabric and cannot test its resistance to point pressure, thus making it difficult to fully understand the overall performance of the fabric.

[0005] To address these issues, we provide a device for testing the elasticity of elastic fabrics used in textile production. Utility Model Content

[0006] The purpose of this invention is to provide a test device for elastic fabric in textile production. By adjusting the position of the electric cylinder with a longitudinal and a transverse adjustment motor, the electric cylinder is then activated to extend its output end upward, causing the pressure plate to press the fabric upward, thus detecting the fabric's resistance to point pressure. This solves the problem that existing elastic fabric test devices cannot detect the fabric's resistance to point pressure.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model is a test device for elastic fabric in textile production, including a base frame; two sliding frames are slidably connected to the top of the base frame, and clamping components for clamping the fabric are provided on the opposite side of the two sliding frames. A pulling component for stretching the fabric is provided on the front of the base frame. A material-lifting component for testing the fabric's resistance to pressure is provided inside the sliding frames. A controller is fixedly provided on the top of the base frame.

[0009] The top material assembly includes a lateral adjusting screw and a guide rail rotatably connected inside the base frame, and a longitudinal adjusting motor fixed to one end of the base frame. The lateral adjusting screw is fixed to the output end of the longitudinal adjusting motor. An adjusting seat is threaded onto the external side of the lateral adjusting screw. A second slide block is slidably connected inside the guide rail. A slide plate is fixed to the top of the adjusting seat and the second slide block. A longitudinal adjusting screw is rotatably connected inside the slide plate. A lateral adjusting motor is fixed to one end of the slide plate, and the longitudinal adjusting screw is fixed to the output end of the lateral adjusting motor. A slider threaded onto the external side of the longitudinal adjusting screw is slidably connected inside the slide plate. An electric cylinder with its output end facing upward is fixed to the external side of the slider. A top pressure device is fixed to the output end of the electric cylinder.

[0010] The present invention is further configured such that the sliding frame includes first sliding blocks slidably connected to the outer sides of the top of the base frame, and mounting plates are fixedly connected to the top of the two first sliding blocks.

[0011] The present invention is further configured such that the clamping assembly includes a U-shaped groove plate fixedly connected to the outside of the mounting plate, a clamping screw is threadedly sleeved at the top center of the U-shaped groove plate, a clamping plate is rotatably connected to the bottom of the clamping screw, and a handwheel is fixedly connected to the top of the clamping screw.

[0012] The present invention is further configured such that a laser rangefinder facing an adjacent mounting plate is fixedly connected to one end of the top of the base frame, and a mounting base is fixedly connected to the other end of the top of the base frame, and a tension sensor is fixedly connected between the mounting base and another mounting plate.

[0013] The present invention is further configured such that the pulling assembly includes a pulling screw rotatably connected to the front of the base frame and a pulling motor fixedly connected to the front of the base frame, and the pulling screw is fixedly connected to the output end of the pulling motor. The external thread of the pulling screw is fitted with a pulling seat, and the pulling seat is fixedly connected to the bottom of the first slide near the pulling motor.

[0014] The present invention is further configured such that the top pressure device includes a sleeve fixedly connected to the output end of the electric cylinder, a pressure sensor is fixedly connected inside the sleeve, and a conical head is movably sleeved inside the sleeve.

[0015] The present invention is further configured such that an upper rubber pad is fixedly connected to the bottom of the clamping plate, and a lower rubber pad is fixedly connected to the bottom of the inner cavity of the U-shaped groove plate.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model adjusts the position of the electric cylinder by starting the longitudinal adjustment motor to drive the transverse adjustment screw to rotate, and by starting the transverse adjustment motor to drive the longitudinal adjustment screw to rotate. Then, by starting the electric cylinder to extend the output end upward, the top pressure device presses the fabric upward. Then, the pressure sensor records the pressure on the fabric, which can more comprehensively detect the fabric's resistance to point pressure.

[0018] 2. This utility model stretches the fabric by pulling one end of the pulling component. At the same time, a tension sensor records the tension on the fabric. When the fabric is pulled to a designated position, a laser rangefinder detects the distance to the nearest sliding frame. Then, the pulling motor is rotated in the opposite direction to retract the fabric. When the tension on the fabric returns to zero, the laser rangefinder detects the distance to the nearest sliding frame again. This allows for rapid detection of the fabric's deformation and thus rapid testing of its tensile strength. Attached Figure Description
