Description

Technical Field

[0001] The utility model relates to the technical field of fabric detection, in particular to a fabric strength machine. Background Art

[0002] In cashmere fabric testing, the tensile breaking strength of cashmere fabric is one of the important performance indicators of fabric. There are many types of textile strength indexes, and the commonly used ones are the tensile breaking strength, top breaking strength, tearing strength, peeling strength, seam strength, tearing strength, tensile elasticity and anti-slip strength of fabrics used for finished product testing. Among them, the fabric strength tester can accurately measure a variety of strength value standards.

[0003] At present, in the prior art, a Chinese patent with announcement number CN212363912U discloses an electronic fabric strength machine, which drives a screw to rotate through a servo motor, and the screw drives a threaded sleeve to move. When the threaded sleeve moves, the connecting rod pushes two sliding seats away from each other, so that the fabric is stretched synchronously by the two sliding seats, avoiding the situation that one end is stretched and the other end is fixed, and the actual stretching performance of the fabric can be better detected. However, the clamping part only clamps the fabric by tightening the screw with a belt. During the stretching process, the fabric will gradually become thinner, and the fabric is easy to slip from the clamping jaws of the clamp, resulting in inaccurate detection results. In view of this, we propose a fabric strength machine. Utility Model Content

[0004] The main purpose of the utility model is to provide a fabric strengthening machine which can solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the fabric strength machine proposed in the utility model comprises a frame, a motor is fixedly connected to the top of the frame, a stretching detection device is arranged below the motor, and the stretching detection device comprises:

[0006] A bidirectional screw rod, the bidirectional screw rod is rotatably connected to the outer wall of the frame;

[0007] A movable seat, wherein the movable seat is penetrated by a bidirectional screw rod and is threadedly connected to the bidirectional screw rod, and the movable seat is penetrated by a guide rod and is slidably connected to the guide rod;

[0008] and a fixing component, wherein a force sensor is fixedly connected to the outer wall of the fixing component.

[0009] Preferably, both ends of the guide rod are fixedly connected to the outer wall of the frame, and the output shaft of the motor is fixedly connected to the bidirectional screw rod. The output shaft of the motor rotates, driving the bidirectional screw rod to rotate, so that the two groups of fixed components move apart or toward each other, which is convenient for subsequent tensile testing of cashmere fabrics.

[0010] Preferably, the fixing assembly comprises a fixing block, the fixing block is threadedly connected to a screw rod, the end of the screw rod is rotatably connected to a pressure plate, and the fixing block is provided with a rubber wheel and a reinforcement plate.

[0011] Preferably, a rotating shaft is rotatably connected in the inner wall of the fixed block, the rotating shaft passes through the rubber wheel and is fixedly connected to the rubber wheel, the rotating shaft passes through the cam and is fixedly connected to the cam, and the rotating shaft is driven by the rubber wheel to rotate slightly, so that the cam can be rotated, and then the reinforcement plate can be moved toward the pressure plate.

[0012] Preferably, a groove is provided on the outer wall of the fixing block, and a return spring is fixedly connected in the groove.

[0013] Preferably, one end of the return spring away from the groove is fixedly connected to the outer wall of the reinforcement plate.

[0014] The utility model provides a fabric strengthening machine, which has the following beneficial effects:

[0015] (1) The fabric strength tester uses a fixing component to enable the fabric to be pressed by the pressing plate. In the subsequent process of fabric stretching, when the fabric gradually becomes thinner and moves relative to the pressing plate, the fabric drives the rubber wheel to rotate, so that the shaft drives the cam to rotate, driving the reinforcement plate to move toward the pressing plate, thereby strengthening the fixation of the fabric and preventing the fabric from slipping out of the fixing block, thereby ensuring the accuracy of the test results.

[0016] (2) The fabric strength tester limits the position of the reinforcement plate through the groove, so that when the cam squeezes the reinforcement plate and moves it toward the pressure plate, the reinforcement plate can move stably to ensure the stability of the reinforcement plate. At the same time, after the test is completed, the reinforcement plate can automatically reset to facilitate the continuation of subsequent tests. BRIEF DESCRIPTION OF THE DRAWINGS
