Description

Technical Field

[0001] This utility model belongs to the field of polyester-cotton fabric testing and relates to a polyester-cotton fabric strength testing device. Background Technology

[0002] Polyester-cotton fabric, commonly known as "Dacron," retains the high strength and good elasticity of polyester fibers while also possessing the high moisture absorption of cotton fibers. It is easy to dye, requires no ironing, and dries quickly after washing. Polyester-cotton fabric comes in various varieties and specifications, including natural-colored, colored, printed, and yarn-dyed fabrics. To ensure product quality during production, strength testing is necessary, requiring a specialized strength testing device. Existing strength testing devices are relatively limited in function, primarily testing tear resistance. Testing abrasion resistance requires additional equipment, making the testing process more cumbersome.

[0003] Currently, a Chinese patent with publication number CN217638389U discloses a polyester-cotton fabric strength testing device, which solves the above problems relatively well. However, in actual use, the moisture content of each polyester-cotton fabric is different. When testing, the moisture content of the polyester-cotton fabric will affect the strength of the polyester-cotton fabric, thus affecting the accuracy of the test. Utility Model Content

[0004] The purpose of this invention is to provide a polyester-cotton fabric strength testing device, which aims to solve the problem that in actual use, the moisture content of each polyester-cotton fabric is different, and the moisture content of the polyester-cotton fabric will affect the strength of the polyester-cotton fabric during testing, thus affecting the accuracy of the test.

[0005] To solve the above-mentioned technical problems, this utility model provides a polyester-cotton fabric strength testing device, including a testing box. A drying component is fixedly connected to the top surface of the testing box, and a heat insulation box is fixedly connected to the inner top surface of the testing box. Two sets of moving blocks are slidably connected inside the testing box, and two sets of mounting boxes are fixedly connected to one side of the two sets of moving blocks. Each of the two sets of mounting boxes has a snap-fit ​​component inside, and a fixing component is fixedly connected to the top surface of the moving blocks. The drying component includes a heating box fixedly connected to the top surface of the testing box. A heating mesh is provided inside the heating box, and one end of the heating mesh is electrically connected to a controller via a power cord. A fan is fixedly connected to the top surface of the heating box, and a dustproof mesh is fixedly connected to the top surface of the fan. The two sets of snap-fit ​​components include telescopic rods disposed inside the two sets of mounting boxes. Compression springs are sleeved on the outer sides of the two sets of telescopic rods, and a moving plate is fixedly connected to one end of each set of compression springs. Each of the two sets of fixing components includes a hydraulic rod fixedly connected to the top surface of the moving block, and a lower pressure plate is fixedly connected to one end of each set of hydraulic rods.

[0006] The testing box has two sets of storage slots inside. One set of storage slots is equipped with a bidirectional lead screw, and the other set of storage slots is equipped with a limit rod. The bidirectional lead screw is used to drive the moving block to move so that it can perform strength testing.

[0007] Limit blocks are fixedly connected to the outer sides of both the bidirectional lead screw and the limiting rod. A servo motor is fixedly connected to one end of the bidirectional lead screw, and the servo motor is used to drive the bidirectional lead screw to rotate.

[0008] The heat insulation box is equipped with a tension gauge, and both ends of the tension gauge are fixedly connected to mounting blocks. The tension gauge is used to detect the moving blocks, thereby determining the tension on the polyester-cotton fabric.

[0009] A motor box is fixedly connected to the side of the testing box, and a measuring ruler is installed inside the testing box. The measuring ruler is used to allow the experimenter to know the length of the polyester-cotton fabric when stretched.

[0010] The surface of the testing box is provided with two sets of protective doors, and each set of protective doors is provided with a pull plate for opening and closing the protective doors.

[0011] The bottom of the testing box is fixedly connected to a support frame, and several sets of ventilation windows are opened on one side of the testing box. The support frame is used to support the device.

[0012] A connecting frame is fixedly connected to one side of the detection box, and a control box is fixedly connected to one side of the connecting frame. The control box is used to control the operation of the device.

[0013] 1. By setting up the fixing and drying components, when using the equipment, the polyester-cotton fabric is placed on the moving block, and the hydraulic rod is activated. The hydraulic rod drives the lower pressure plate to move, and the lower pressure plate contacts the top surface of the moving block to fix the polyester-cotton fabric, preventing it from falling off during testing. After fixing, the fan is activated, and the air blown out by the fan is heated by the heating grid to become hot air. The hot air dries the polyester-cotton fabric, ensuring that each test is conducted under the same conditions, thus improving the accuracy and repeatability of the test results.

[0014] 2. Through the design of the snap-fit ​​assembly and mounting box, during use, sliding the movable plate compresses the compression spring and telescopic rod. At this point, the mounting box can be opened, allowing the mounting block to be removed and the force gauge replaced. This enables users to select the appropriate force gauge according to their actual needs, adapting the device to various testing scenarios and requirements, thus improving its versatility and flexibility.
