[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides: a tensile test device for packaging material production, such as Figure 1-4As shown, it includes a mounting base plate 1 and a tension tester 8 mounted on the upper surface of the mounting base plate 1, a connecting column 5 is arranged on the side of the tension tester 8, a support plate 6 is fixedly mounted on the other end of the connecting column 5, a rotating rod 7 is threadedly passed through the support plate 6, a connecting rod 9 is fixedly connected to the bottom end of the rotating rod 7, and a fixing component for fixing the test object is arranged on the upper surface of the mounting base plate 1 and the bottom end of the connecting rod 9; by placing the two ends of the test object between the movable extrusion plate 13 and the fixed extrusion plate 14 respectively, the threaded rod 19 is rotated to drive the movable extrusion plate 13 close to the fixed extrusion plate 14, so that the two ends of the test object are fixed and then the tension test is performed, so as to avoid using a hook to pull the test object and cause single-point damage at the pulling point, so as to fully reflect the overall tensile performance of the test object, and the rotating rod 7 is rotated to drive a group of fixing components to rotate, so as to test the tensile force of the test object after rotation, so as to increase the applicability of the tensile testing device.

[0024] The fixed component includes a fixed frame 11, a mounting block 12, a movable extrusion plate 13, a fixed extrusion plate 14 and an extrusion module. The mounting block 12 is fixedly installed inside the fixed frame 11, the fixed extrusion plate 14 is fixedly installed on the inner wall of the fixed frame 11, and the movable extrusion plate 13 is movably set inside the fixed frame 11.

[0025] Preferably, the extrusion module includes a limiting column 16, a threaded rod 19, a movable column 20 and a compression spring 21, one end of the threaded rod 19 is threaded through the mounting block 12, and the movable extrusion plate 13 is located on the side of the mounting block 12 close to the fixed extrusion plate 14, and the movable extrusion plate 13 is rotatably connected to one end of the threaded rod 19. When the threaded rod 19 is rotated, the threaded rod 19 threads through the mounting block 12 and drives the movable extrusion plate 13 to move away from the mounting block 12, and the movable extrusion plate 13 is rotatably connected to the threaded rod 19 to prevent the movable extrusion plate 13 from rotating with the threaded rod 19.

[0026] Furthermore, two groups of limit columns 16, movable columns 20 and compression springs 21 are each provided, and the two groups of compression springs 21 are sleeved on the corresponding outer arc surfaces of the movable columns 20, and the two groups of limit columns 16 are fixedly installed on one end of the movable column 20 away from the movable extrusion plate 13, and the two groups of movable columns 20 are fixedly connected to the movable extrusion plate 13. When the movable extrusion plate 13 moves toward the fixed extrusion plate 14, it drives the movable column 20 to move synchronously, and the movable column 20 compresses the compression spring 21 while moving. When the operating threaded rod 19 drives the movable extrusion plate 13 away from the fixed extrusion plate 14, the compression spring 21 provides an elastic force away from the fixed extrusion plate 14, thereby assisting the threaded rod 19 to drive the movable extrusion plate 13 away from the fixed extrusion plate 14. At the same time, the two groups of movable columns 20 are connected to the movable extrusion plate 13, further ensuring that the movable extrusion plate 13 will not rotate with the threaded rod 19.

[0027] Furthermore, two groups of movable columns 20 are symmetrically arranged on both sides of the threaded rod 19, and a movable groove 22 corresponding to the limiting column 16 is opened inside the mounting block 12, and a limiting groove 23 corresponding to the movable column 20 is opened inside the mounting block 12 and on the side of the movable groove 22.

[0028] It is worth mentioning that a transparent front baffle plate 2 is slidably provided on the upper surface of the mounting base plate 1, a handle 3 is fixedly installed on the side of the transparent front baffle plate 2, and a snap-in protrusion 17 is fixedly provided on the lower surface of the transparent front baffle plate 2.

[0029] Specifically, a support seat 10 is fixedly installed on the upper surface of the mounting base 1, a group of fixing frames 11 and a mounting block 12 are fixedly installed on the upper surface of the support seat 10, and another group of fixing frames 11 is fixedly installed on the lower surface of the connecting rod 9. The two groups of fixing components are located in the same vertical plane, and the two ends of the test object are respectively fixed inside the two groups of fixing components, so as to facilitate the tensile test of the test object.

[0030] In addition, several groups of anti-slip beans 15 are provided on the corresponding surfaces of the movable extrusion plate 13 and the fixed extrusion plate 14, and a control box 4 is provided on the upper surface of the installation base plate 1 and located on the side of the tensile tester 8.
