Description

Technical Field

[0001] This utility model relates to the field of film tension testing technology, and in particular to a film tension testing device. Background Technology

[0002] Film tension testing is used to assess and control the tension state of films (such as plastic films, paper, aluminum foil, etc.) during processing in industries such as packaging, printing, and coating. Proper tension control is crucial for maintaining material stability, improving product quality, and reducing scrap rates in production.

[0003] In the process of laminating the substrate, in order to avoid problems such as wrinkles and curling, a tensile test is performed on the lamination before lamination. However, traditional testing methods mostly rely on manual movement. During the test, the direction of manual movement can easily cause the direction of tension to deviate, which in turn leads to deviations in the tensile test results of the lamination. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where traditional film tensile testing methods mostly rely on manual movement, which can easily lead to deviations in the direction of tensile force due to the influence of the direction of manual movement during testing, resulting in deviations in the film tensile testing results. Therefore, this invention proposes a film tensile testing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a film tension testing device, comprising a pad, a fixing plate mounted on the upper surface of the pad, a fixing shaft fixedly mounted on one side of the fixing plate, a roll detachably mounted on the arc surface of the fixing shaft, a roll of material sleeved on the arc surface of the roll, a testing structure provided on the upper surface of the pad, the testing structure comprising an adjusting plate and a connecting plate, both the adjusting plate and the connecting plate being fixedly connected to the pad, a lead screw rotatably connected inside the adjusting plate, one end of the lead screw being rotatably connected to the connecting plate, a fixing frame threadedly connected to the arc surface of the lead screw, a push-pull force gauge fixedly mounted on the fixing frame, guide rods slidably inserted at both ends of the fixing frame, the two ends of the guide rods being fixedly connected to the adjusting plate and the connecting plate respectively, and a limiting component for fixing the roll of material provided at the pulling end of the push-pull force gauge.

[0006] The effect achieved by the above components is that the roll material can be quickly connected to the tension end of the push-pull force gauge by means of the limiting component, thereby driving the push-pull force gauge to move by means of the lead screw, and using the push-pull force gauge to test the tensile strength of the roll material.

[0007] Preferably, the limiting component includes a buckle, one end of which is fixedly connected to the pulling end of the push-pull force gauge, and the other end of which is detachably connected to a connecting buckle. A positioning plate is fixedly connected to one side of the connecting buckle, and a rectangular plate is fixedly connected to one end of the positioning plate. An adjusting frame is fixedly connected to the upper surface of the rectangular plate, and a screw is threaded into the adjusting frame. Slide rails are fixedly connected to both sides of the upper surface of the rectangular plate, and sliding columns are slidably connected inside the slide rails. The upper ends of the two sliding columns are fixedly connected to the same pressure plate, and a partition is fixedly connected to the side of the two slide rails that are close to each other. The pulling end of the push-pull force gauge is parallel to the pad.

[0008] The effect achieved by the above-mentioned components is that the screw can be used to press the pressure plate downwards, thereby clamping and fixing one end of the roll material.

[0009] Preferably, a rubber pad is fixedly connected to the lower surface of the pressure plate, and the lower surface of the rubber pad is uniformly provided with anti-slip texture.

[0010] The effect achieved by the above components is to increase the friction between the pressure plate and the surface of the roll material.

[0011] Preferably, a spring is fixedly connected to the lower end of the sliding column, and the lower end of the spring is fixedly connected to the rectangular plate.

[0012] The effect achieved by the above components is to provide a rebound force to the slide, making it easier to remove the roll material from between the partition and the pressure plate.

[0013] Preferably, a top ball is fixedly connected to the lower end of the screw, and the arc surface of the top ball abuts against the pressure plate.

[0014] The effect achieved by the above components is to reduce the friction between the screw and the pressure plate.

[0015] Preferably, a pointer is fixedly connected to one end of the rectangular plate, and a scale is fixedly connected to the upper surface of the pad, with the scale located directly below the pointer.

[0016] The effect achieved by the above components is that the deformation of the coating can be obtained with the help of a pointer and a ruler.

[0017] Preferably, one end of the screw is fixedly connected to a crank handle, and the arc surface of the crank handle is uniformly provided with anti-slip protrusions.

[0018] The effect achieved by the above components is to facilitate the tester in rotating the lead screw and adjusting the position of the push-pull force gauge.

[0019] In summary, the beneficial effects of this utility model are as follows:

[0020] In this invention, one end of the roll material can be fixed by means of existing components, and then the tension of the film can be tested by using a screw to drive the push-pull force gauge. The whole structure has the advantages of accurate measurement and simple operation. Attached Figure Description

[0027] Reference Figure 1 As shown, this utility model provides a technical solution: a film tension testing device, including a pad 1, a fixing plate 2 installed on the upper surface of the pad 1, a fixing shaft 3 fixedly installed on one side of the fixing plate 2, a roll 4 detachably installed on the arc surface of the fixing shaft 3, a roll material 5 sleeved on the arc surface of the roll 4, and a testing structure 6 provided on the upper surface of the pad 1.

[0028] The following section will explain the specific settings and functions of the test structure 6 and the limit component 66.

[0029] Reference Figure 2As shown in this embodiment: the test structure 6 includes an adjusting plate 61 and a connecting plate 62. Both the adjusting plate 61 and the connecting plate 62 are fixedly connected to the pad 1. A lead screw 63 is rotatably connected inside the adjusting plate 61. One end of the lead screw 63 is rotatably connected to the connecting plate 62. A fixing frame 64 is threadedly connected to the arc surface of the lead screw 63. A push-pull force gauge 7 is fixedly installed on the fixing frame 64. Guide rods 65 are slidably inserted at both ends of the fixing frame 64. The two ends of the guide rods 65 are fixedly connected to the adjusting plate 61 and the connecting plate 62, respectively. The tension end of the push-pull force gauge 7 is provided with a limiting component 66 for fixing the roll material 5. This achieves the effect of quickly connecting the roll material 5 to the tension end of the push-pull force gauge 7 with the help of the limiting component 66, thereby driving the push-pull force gauge 7 to move with the help of the lead screw 63, and testing the tensile strength of the roll material 5 with the help of the push-pull force gauge 7.

[0030] Reference Figure 3 , Figure 4 and Figure 5As shown in this embodiment: the limiting component 66 includes a buckle 6601, one end of which is fixedly connected to the pulling end of the push-pull force gauge 7, and the other end of which is detachably connected to a connecting buckle 6602. A positioning plate 6603 is fixedly connected to one side of the connecting buckle 6602, and a rectangular plate 6604 is fixedly connected to one end of the positioning plate 6603. An adjusting bracket 6605 is fixedly connected to the upper surface of the rectangular plate 6604, and a screw is threaded into the adjusting bracket 6605. The upper surface of the rod 6609 and the rectangular plate 6604 are both fixedly connected to slide rails 6606. Slide columns 6607 are slidably connected inside the slide rails 6606. The upper ends of the two slide columns 6607 are fixedly connected to the same pressure plate 6608. A partition plate 6613 is fixedly connected to the side of the two slide rails 6606 that is close to each other. This allows the screw 6609 to press down on the pressure plate 6608, thereby clamping and fixing one end of the roll material 5. A rubber pad 6610 is fixedly connected to the lower surface of the pressure plate 6608. The lower surface of the rubber pad 6610 is evenly provided with anti-slip textures, which increases the friction between the pressure plate 6608 and the surface of the roll material 5. A spring 6611 is fixedly connected to the lower end of the sliding column 6607. The lower end of the spring 6611 is fixedly connected to the rectangular plate 6604, which provides a rebound force to the sliding column 6607, facilitating the removal of the roll material 5 from between the partition plate 6613 and the pressure plate 6608. A top ball 6612 is fixedly connected to the lower end of the screw 6609. The arc surface of the top ball 6612 abuts against the pressure plate 6608, reducing the friction between the screw 6609 and the pressure plate 6608. A pointer 67 is fixedly connected to one end of the rectangular plate 6604, and a scale 68 is fixedly connected to the upper surface of the pad 1. The scale 68 is located directly below the pointer 67, allowing the deformation of the coating material to be measured using the pointer 67 and the scale 68. One end of the screw 6609 is fixedly connected to a crank handle 69. The arc surface of the crank handle 69 is evenly provided with anti-slip protrusions, which makes it convenient for testers to rotate the lead screw 63 and adjust the position of the push-pull force gauge 7.

[0031] Working principle: When tension testing of the coating is required, the roll material 5 is directly placed on the roll 4, and then one end of the roll material 5 is pulled open and placed between the partition plate 6613 and the pressure plate 6608. Then, the screw 6609 is rotated, so that the screw 6609 presses the pressure plate 6608 with the help of the thread. The pressure plate 6608 presses one end of the roll material 5 onto the partition plate 6613 with the help of the rubber pad 6610, thereby achieving the effect of fixing one end of the roll material 5. Next, the buckle 6601 of the push-pull force gauge 7 is connected to the connecting buckle 6602. At this time, the crank handle 69 is directly turned, so that the crank handle 69 drives the lead screw 63 to rotate. The lead screw 63 drives the push-pull force gauge 7 to slide along the guide rod 65 with the help of the thread. At this time, the roll material 5 begins to be stretched, and the push-pull force gauge 7 begins to record the tension data of the roll material 5.

[0032] When it is necessary to measure the deformation of the roll 5, record the initial position of the pointer 67 relative to the scale 68 before starting to pull the roll 5, and record the final position of the pointer 67 relative to the scale 68 after pulling the roll 5, so as to obtain the deformation of the roll 5.

[0033] After the tension test of the roll material 5 is completed, the screw 6609 is rotated in the opposite direction to move the screw 6609 upward. At this time, the spring 6611 will give the slide 6607 an upward elastic force. The slide 6607 will drive the pressure plate 6608 to move upward. At this time, the roll material 5 can be directly removed from between the pressure plate 6608 and the partition 6613.

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
