Through the cooperation between the mounting plate 2 and the clamping mechanism 3, the two ends of the coated fabric can be clamped and fixed to prevent sliding and falling off during the stretching process. When the control switch 6 is started to move the mounting plate 2, the fabric is stretched, and the impact between the pressure plate 51 and the tension sensor 7 is buffered by the buffer spring 53 in the buffer assembly 5, thereby reducing the impact force on the surface of the tension sensor 7 and detecting the tension.

A movable groove 201 is provided in the middle of the left end of the mounting plate 2, and limited sliding grooves 202 are respectively provided on the front and rear sides of the left end of the mounting plate 2. The outer wall of the bidirectional screw 32 penetrates to the bottom of the movable groove 201 and is rotatably connected therebetween, and the upper and lower threaded sleeves 34 are both arranged inside the movable groove 201.

[0027] like Figure 3 As shown, the utility model provides a technical solution for a tensile testing device for coated fabrics: sliders 331 are fixedly connected to the front and rear sides of the right ends of the upper and lower clamping plates 33, respectively, and the outer wall of the slider 331 is slidably connected to the inside of the limiting slide groove 202. The slider 331 slides up and down inside the limiting slide groove 202, so that when the threaded sleeve 34 is displaced on the bidirectional screw 32, the threaded sleeve 34 is limited.

[0028] like Figure 4 As shown, the utility model provides a technical solution for a tensile testing device for coated fabrics: the front and rear sides of the right side of the inner wall of the U-shaped frame plate 1 are respectively fixedly connected with a limit slide bar 8, the front and rear sides of the right side mounting plate 2 are respectively fixedly connected with a sleeve plate 9, and the middle parts of the two sleeve plates 9 are provided with a sliding hole 901 that passes through the left and right sides, and the interior of the sliding hole 901 is sleeved with the outer wall of the limit slide bar 8, and the output end of the hydraulic cylinder 4 and the two limit slide bars 8 are arranged on the same horizontal plane, and when the hydraulic cylinder 4 moves the mounting plate 2 on the right side to the right, the sliding hole 901 in the sleeve plate 9 slides along the outer wall of the limit slide bar 8, so that the movement of the right side mounting plate 2 is limited to prevent skewing.

[0029] like Figure 5As shown, the utility model provides a technical solution of a tensile testing device for coated fabrics: the buffer component 5 includes a pressing plate 51, and connecting rods 52 are fixedly connected to the front and rear sides of the right end of the pressing plate 51 respectively, and the right side of the outer wall of the connecting rod 52 penetrates into the interior of the U-shaped frame plate 1 and is fixedly connected to the right end of the left mounting plate 2, and the outer walls of the two connecting rods 52 are sleeved with buffer springs 53, and the right ends of the two buffer springs 53 are fixedly connected to the right end of the left mounting plate 2, and the left sides of the two buffer springs 53 are fixedly connected to the inner wall of the U-shaped frame plate 1, and the middle part of the left side of the U-shaped frame plate 1 is fixedly connected with a connecting plate 11, and the tension sensor 7 is arranged on the left side of the connecting plate 11, and the connecting plate 11 and the two connecting rods 52 are arranged on the same horizontal plane, and the impact of the pressing plate 51 on the surface of the tension sensor 7 is slowed down by utilizing the elasticity of the buffer spring 53, so as to improve the service life of the tension sensor 7.

[0030] The following is a detailed description of the working principle of this coated fabric tensile testing device.

[0031] like Figure 1-5 As shown, first, the tension sensor 7 is connected to the tension display screen through a wire, the hydraulic cylinder 4 is electrically connected to the control switch 6, and the control switch 6 is connected to an external power supply. When the coated fabric is subjected to tension detection, first, the left-side twist knob 31 is rotated to drive the bidirectional screw 32 to rotate inside the movable groove 201, so that the threaded sleeves 34 on the upper and lower sides are driven to rotate on the bidirectional screw 32, and in the process of movement, the slider 331 slides along the inner wall of the limiting slide groove 202, so as to limit the movement of the clamping plates 33 on the upper and lower sides, so that the clamping plates 33 on the upper and lower sides are driven to shrink and slide toward the middle of the mounting plate 2, thereby clamping one end of the coated fabric, and then, synchronously The clamping mechanism 3 on the right side is operated to clamp the other side of the coated fabric. The rubber pad 35 can increase the friction between the clamping plate 33 and the coated fabric, so that the fabric is tightly clamped and fixed to prevent it from falling off. Then, the hydraulic cylinder 4 is started, and the output end of the hydraulic cylinder 4 drives the clamping mechanism 3 on the right side to pull to the right to stretch the coated fabric. During the stretching process, the connecting rod 52 is forced to move to the right to squeeze the buffer spring 53, so that the buffer spring 53 can buffer the impact force between the pressure plate 51 and the tension sensor 7, reduce the damage to the surface of the tension sensor 7, and increase the service life of the tension sensor 7. The tension sensor 7 detects the magnitude of the tension and displays the data through the tension display screen.

[0032] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
