[0001] The utility model relates to the technical field of membrane material processing equipment, in particular to a membrane material strength tensile testing machine. Background Art

[0002] A thin film is a thin and soft transparent sheet made of plastic, adhesive, rubber or other materials. The scientific explanation of a thin film is: a two-dimensional material formed by depositing atoms, molecules or ions on the surface of a substrate, such as: optical thin film, composite thin film, superconducting thin film, polyester thin film, nylon thin film, plastic thin film, etc. Thin films are widely used in industries such as electronics and electrical appliances, machinery, printing, etc. Thin film materials refer to thin metal or organic layers with a thickness ranging from single atoms to several millimeters. Electronic semiconductor functional devices and optical coating are the main applications of thin film technology.

[0003] In the prior art, strength tensile tests are often randomly inspected by quality inspection personnel before batch processing and during the production process. This is not only relatively troublesome to operate, but also the inspection volume is small, which easily leads to the appearance of batch defective products. However, frequent inspections will greatly increase the labor intensity of quality inspection personnel and delay production, which does not meet the requirements of high-efficiency production of enterprises. Therefore, we propose a membrane material strength tensile testing machine to solve the above problems. Content of the Utility Model

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1.

Specific implementation manner

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] Referring to Figures 1-4 , a material strength tensile testing machine for film materials, including a mounting bracket 1, an auxiliary roller 2 is arranged on the mounting bracket 1, and a driving mechanism is arranged on the mounting bracket 1, and a detection mechanism is arranged on the driving mechanism;

[0024] In the above design, the mounting bracket 1 is arranged between the production equipment and the winding equipment. Among them, the auxiliary roller 2 is used to assist the film material to move towards the winding equipment. After each roll of film material is wound by the winding equipment, the detection mechanism can be started to operate. It can not only perform detection operations before a roll of film material is wound to ensure the product quality of the film material, but also because it is exactly the time to replace the winding cylinder at this time, the detection operation will not delay the winding operation, avoiding reducing the production efficiency. At the same time, it can also cut the film material to facilitate the user's winding operation.

[0025] The driving mechanism includes a U-shaped bracket 3 fixedly connected to the mounting bracket 1, a servo push rod 4 fixedly connected to the lower surface of the U-shaped bracket 3, a cross frame 5 fixedly connected to the lower end of the servo push rod 4, two ends of the cross frame 5 are slidably connected with a buckle plate 6, and a return spring 7 is arranged between the buckle plate 6 and the cross frame 5. Among them, the buckle plate 6 is arranged above the auxiliary roller. The two ends of the return spring 7 are respectively fixedly connected to the cross frame 5 and the buckle plate 6, and the detection mechanism is arranged in the middle of the cross frame 5;

[0026] In this design, when the winding equipment completes the winding of a roll of material, the servo push rod 4 can be controlled to operate. At this time, the servo push rod 4 drives the cross frame 5 to move downward. The buckle plate 6 on the cross frame 5 presses the film material on the auxiliary roller 2. On the one hand, it realizes the fixation of the film material, and on the other hand, it also makes the auxiliary roller 2 unable to rotate. Subsequently, the cross frame 5 can continue to move, and the return spring 7 deforms and uses the elastic potential energy to be converted into pressure to ensure the fixation of the buckle plate 6 on the film material. As the detection mechanism moves downward, the detection mechanism will stretch the film material, thereby realizing the stretching detection operation of the film material;

[0027] A cutting component is also provided at a position of the mounting bracket 1 close to the auxiliary roller 2.

[0028] More specifically, the cutting component includes a cutting table 8 fixedly connected to the mounting bracket 1, and a cutting knife 9 is slidably connected to the mounting bracket 1. One side of the cutting knife 9 is rotatably connected to a shifting block 10 through a spring, and pushing blocks 11 abutted against the shifting block 10 are arranged at both ends of the cross frame 5;

[0029] In the above design, when the cross frame 5 moves, after the pushing block 11 abuts against the shifting block 10, it drives the shifting block 10 to rotate. When the cross frame 5 moves upward, after the pushing block 11 abuts against the shifting block 10, it can drive the cutting knife 9 to move upward, and then the cutting knife 9 is used to cut the film material. At this time, the film material has passed the tensile test. Even if it is not broken due to the tensile test, it will be scrapped due to excessive plastic deformation caused by excessive stretching. Therefore, two cutting knives 9 are provided to cut off this section of the film material.

[0030] Furthermore, an elastic pad 12 is fixedly connected to one side of the cutting knife 9 close to the cutting table 8, a magnetic attraction block 13 is also fixedly connected to the cutting knife 9, and a magnet 14 is fixedly connected to the side wall of the mounting bracket 1 close to the magnetic attraction block 13;

[0031] In this design, before the cutting knife 9 contacts the film material, the elastic pad 12 first presses the film material on the cutting table 8, and then the cutting operation is carried out, which can avoid the cutting knife 9 driving the film material to deform and cause damage to the cut film material. The magnetic attraction block 13 is provided in cooperation with the magnet 14 to keep the elastic pad 12 clamping the end of the cut part of the film material after the cross frame 5 continues to move upward under the cooperation of the magnetic attraction block 13 and the magnet 14, so as to facilitate the user's next winding operation.

[0032] Furthermore, the detection mechanism includes a mounting plate 15 rotatably connected to the lower surface of the cross frame 5. A pressing plate 16 is arranged on the mounting plate 15, and a tensile sensor is arranged on the pressing plate 16. A spring rod is fixedly connected to the mounting bracket 1, and an auxiliary block 19 is arranged at the upper end of the spring rod. A clamping groove is formed on the pressing plate 16, and a clamping block 17 matched with the clamping groove is arranged on the auxiliary block 19;

[0033] Two pressing plates 16 are provided, which can simultaneously perform tensile tests on the materials on both sides, or only start the detection mechanism on one side for detection. Generally, the tensile test of the film material mainly detects the fracture position after the deformation reaches a certain degree after stretching. At this time, the specific reading of the tensile sensor is not required. Only by judging the position of the detection component when the tensile sensor cannot sense the tensile force after the servo push rod 4 extends, the tensile test can be completed.

[0034] Furthermore, a vertical rod 18 is slidably connected to the upper end of the spring rod, and the vertical rod 18 is rotatably connected to the auxiliary block 19;

[0035] In this design, the vertical rod 18 on the spring rod cooperates with the auxiliary block 19 to clamp the film material and move along with the frictional force. At this time, the tension sensor can obtain the specific reading of the tension after removing the frictional interference of the pressing block and the auxiliary block 19, so as to obtain more accurate tension test data.

[0036] Furthermore, the buckle plate 6 is arc-shaped, and the inner diameter of the buckle plate 6 is equal to the outer diameter of the auxiliary roller 2.

[0037] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
