[0002] The Light Box Fabric Force Tester is a test device that tests the mechanical properties of light box fabric materials by applying tensile force. It provides accurate test data, helping manufacturers and users understand how light box fabrics perform under different stress conditions.
[0003] The existing tensile testing device for light box cloth applies tension to the light box cloth by using a tension arm. The tension arm serves as a force transmission and application component to ensure that the tension can accurately act on the sample. The tension arm can usually only provide static or single-directional tension, which makes it difficult to fully simulate the complex mechanical effects that the light box cloth is subjected to in actual applications, such as rolling, bending, torsion, etc., and the test results are incomplete.
[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content
[0005] In response to the shortcomings of the existing technology, the purpose of the utility model is to provide a tensile testing device for high-strength light box cloth. The cloth is subjected to continuous tension under the continuous rotation of the drum to evaluate its strength and durability. The rotation of the drum can more realistically simulate the mechanical effects such as rolling and stretching that the light box cloth is subjected to in actual applications. This multi-directional force can more comprehensively evaluate the mechanical properties and durability of the light box cloth, and improve the comprehensiveness of the tensile test results.

[0007] The utility model is further configured as follows: a fixed block is fixedly installed on both sides of the inner cavity of the drum, a positioning bolt is movably inserted and connected to the opposite back surfaces of the two fixed blocks, and a splint is movably connected to the opposite surfaces of the two positioning bolts, and the cloth is located between the two splints.
[0008] The utility model is further configured as follows: a display screen is fixedly installed on the right end of the vertical plate.
[0009] The utility model is further configured as follows: the diameter of the discharge roller is the same as the diameter of the drum.
[0010] In summary, the present invention has the following beneficial effects:
[0011] 1. The fabric is subjected to continuous tension under the continuous rotation of the drum to evaluate its strength and durability.

[0018] The present invention is described in detail below with reference to the accompanying drawings.
[0019] A tensile testing device for high-strength light box cloth, such as Figures 1 to 2 The present invention relates to a roller 5 for conveying the raw material of the raw material to the roller 5, and a roller 5 for conveying the raw material to the roller 5. As shown in the figure, it includes a base 1, a vertical plate 2 is fixedly installed on the rear side of the upper end of the base 1, a feeding roller 3 is movably connected to the upper side of the front end of the vertical plate 2, the outer surface of the feeding roller 3 is movably connected to the cloth 4, and the lower side of the front end of the vertical plate 2 is movably connected to the drum 5. The diameter of the feeding roller 3 is the same as the diameter of the drum 5, the rear end of the drum 5 is fixedly installed with a rotating shaft 6, the rear end of the rotating shaft 6 is fixedly installed with a servo motor 7, the surface of the drum 5 is provided with a feeding groove 8, the cloth 4 is movably inserted into the interior of the drum 5 through the feeding groove 8, and a force sensor 9 is fixedly installed on the rear side of the outer surface of the rotating shaft 6. By starting the driving motor on the rear side of the feeding roller 3, the feeding roller 3 is driven to rotate a certain angle, so that the cloth 4 is discharged until the lower part of the cloth 4 passes through the feeding groove 8 and enters the drum 5. At this time, the feeding roller 3 stops rotating, and the rotating shaft 6 is driven to rotate by the servo motor 7, thereby driving the drum 5 to rotate. Under the continuous rotation of the drum 5, the cloth 4 is subjected to continuous tension. At this time, the deformation, breakage, etc. of the cloth 4 can be observed and recorded to evaluate its strength and durability. A force sensor 9 is set on the rotating shaft 6. The force sensor 9 works based on the principle that an elastic body produces elastic deformation under the action of an external force. When the rotating shaft 6 drives the roller 5 to rotate, thereby applying tension to the cloth 4, the force sensor 9 will sense this tension and produce corresponding deformation. The elastic body of the sensor (such as a resistance strain gauge) changes its resistance value with the deformation. This change is converted into a voltage or current signal through the measuring circuit. These electrical signals are then transmitted to the control system or data acquisition system for further processing and analysis, such as displaying the tension value, recording data, etc., and the tension test data is displayed in real time through the display screen 13. The way the roller 5 rotates can more realistically simulate the mechanical effects such as rolling and stretching that the light box cloth is subjected to in actual application. This multi-directional force can more comprehensively evaluate the mechanical properties and durability of the light box cloth, and improve the comprehensiveness of the tension test results.
[0020] A display screen 13 is fixedly mounted on the right end of the vertical plate 2 , and the tensile test data is displayed in real time via the display screen 13 .
[0021] like Figure 2 As shown, a fixing block 10 is fixedly installed on both sides of the inner cavity of the drum 5, and a positioning bolt 11 is movably connected to the opposite back surfaces of the two fixing blocks 10, and a clamping plate 12 is movably connected to the opposite surfaces of the two positioning bolts 11. The cloth 4 is located between the two clamping plates 12. The positioning bolts 11 on both sides are manually rotated to push the clamping plates 12 on both sides to move left and right. Since the positioning bolts 11 are movably connected to the clamping plates 12 through bearings, the positioning bolts 11 can push the clamping plates 12 on both sides to move and approach each other when the fixed block 10 rotates, so that the lower part of the cloth 4 can be clamped, ensuring that the light box cloth can be stably subjected to the tension applied by the drum 5 during the test.
[0022] Working principle: By starting the driving motor on the rear side of the discharge roller 3, the discharge roller 3 is driven to rotate a certain angle, so that the cloth 4 is discharged until the lower part of the cloth 4 passes through the feed slot 8 and enters the drum 5. At this time, the discharge roller 3 stops rotating, and the positioning bolts 11 on both sides are manually rotated to push the clamping plates 12 on both sides to move left and right. Since the positioning bolts 11 are movably connected to the clamping plates 12 through bearings, the positioning bolts 11 can push the clamping plates 12 on both sides to move and approach each other when the fixed block 10 rotates, so that the lower part of the cloth 4 can be clamped, ensuring that the light box cloth can be stably subjected to the tension applied by the drum 5 during the test. The servo motor 7 drives the rotating shaft 6 to rotate, thereby driving the drum 5 to rotate. Under the continuous rotation of the drum 5, the cloth 4 is subjected to continuous tension. At this time, the deformation, breakage, etc. of the cloth 4 can be observed and recorded to evaluate its strength and durability. A force sensor 9 is set on the rotating shaft 6. The force sensor 9 works based on the principle that an elastic body produces elastic deformation under the action of an external force. When the rotating shaft 6 drives the roller 5 to rotate, thereby applying tension to the cloth 4, the force sensor 9 will sense this tension and produce corresponding deformation. The elastic body of the sensor (such as a resistance strain gauge) changes its resistance value with the deformation. This change is converted into a voltage or current signal through the measuring circuit. These electrical signals are then transmitted to the control system or data acquisition system for further processing and analysis, such as displaying the tension value, recording data, etc., and the tension test data is displayed in real time through the display screen 13. The way the roller 5 rotates can more realistically simulate the mechanical effects such as rolling and stretching that the light box cloth is subjected to in actual application. This multi-directional force can more comprehensively evaluate the mechanical properties and durability of the light box cloth, and improve the comprehensiveness of the tension test results.
[0023] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
