Description

Technical Field

[0001] This utility model belongs to the field of mechanical equipment technology, and more specifically relates to a device for testing the abrasion resistance of food packaging bags. Background Technology

[0002] To understand the actual abrasion resistance of packaging bags and better select the appropriate packaging material for packaging foods with different requirements, abrasion resistance tests are necessary. The traditional method involves rubbing the packaging bags with a device equipped with a grinding head to test their abrasion resistance and lifespan. However, the grinding head rotates and contacts the surface of the packaging bag until it breaks. This grinding method does not reflect the friction conditions that occur in real life, and the test results obtained are not very meaningful. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a wear resistance testing device for food packaging bags. By using different friction surfaces, the wear test of the packaging bags can be made closer to real life, and the test data can be more effective.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a food packaging bag abrasion resistance testing device, including a fixed platform and a sliding support, a friction platform is provided on the fixed platform, a plurality of different friction surfaces are provided on the friction platform, a mounting frame is slidably connected to the sliding support, a packaging bag clamping mechanism is provided on the mounting frame, the mounting frame is located above the friction platform, a reciprocating drive mechanism is provided between the mounting frame and the sliding support, and the sliding support is slidably connected to the ground.

[0005] Furthermore, the clamping mechanism includes several grippers, with an arc-shaped support block disposed in the middle of the grippers. The arc-shaped support block is vertically connected to the mounting frame and is provided with a lifting drive mechanism.

[0006] Furthermore, the mounting frame is provided with an adjustment plate, the gripper is located on the adjustment plate, the adjustment plate is provided with a waist-shaped groove, a fixing bolt is provided between the groove and the mounting frame, and the fixing bolt is threadedly connected to the mounting frame.

[0007] Furthermore, a waste chip trough is provided around the friction table.

[0008] Furthermore, the arc-shaped support block is made of an elastic material.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: During the test, the positions of several grippers are adjusted so that they are clamped on the edge of the packaging bag. Then, the arc-shaped support block descends to tighten the center of the packaging bag downwards, so that the surface of the packaging bag contacts the friction surface on the friction table. Then, the mounting frame moves back and forth, so that the packaging bag can be subjected to friction test on the friction surface. After the test is completed, a new packaging bag is picked up and clamped. Then, the support is moved so that the convex surface of the packaging bag is aligned with a different friction surface, and the friction test is carried out again. Different friction surfaces make the friction test of the packaging bag closer to real life, and the test data is more effective. Attached Figure Description

[0016] Reference Figures 1 to 3The present invention will be further described below.

[0017] A food packaging bag abrasion resistance testing device includes a fixed platform 1 and a translational support 2. A friction platform 3 is provided on the fixed platform 1, and several different friction surfaces 4 are provided on the friction platform 3. A mounting frame 5 is slidably connected to the translational support 2. A packaging bag clamping mechanism is provided on the mounting frame 5. The mounting frame 5 is located above the friction platform 3. A reciprocating drive mechanism is provided between the mounting frame 5 and the translational support 2. The translational support 2 is slidably connected to the ground.

[0018] Specifically, different friction surfaces 4 simulate various surfaces in daily life, such as cement roads, asphalt roads, tile roads, brick roads, walls, etc.

[0019] Specifically, the reciprocating drive mechanism can be a linear motor or a cylinder 8, which drives the mounting frame 5 to move back and forth, causing repeated friction between the packaging bag and the friction surface 4.

[0020] like Figure 2 and Figure 3 As shown in the example, the preferred clamping mechanism includes a plurality of grippers 6, with an arc-shaped support block 7 disposed in the middle of the plurality of grippers 6. The arc-shaped support block 7 is vertically connected to the mounting frame 5 and is provided with a lifting drive mechanism.

[0021] Specifically, the lifting drive mechanism is a cylinder 8.

[0022] like Figure 2 As shown in this example, preferably, the mounting frame 5 is provided with an adjusting plate 9, the gripper 6 is located on the adjusting plate 9, the adjusting plate 9 is provided with a waist-shaped groove, and a fixing bolt 10 is provided between the waist-shaped groove and the mounting frame 5, and the fixing bolt 10 is threadedly connected to the mounting frame 5.

[0023] Specifically, after loosening the fixing bolt 10, the adjusting plate 9 can be moved to adjust the position of each gripper 6, making it convenient to clamp packaging bags of different sizes for friction tests.

[0024] like Figure 1 As shown in this example, preferably, a waste chip trough 11 is provided around the friction table 3 to prevent waste chips generated by friction from falling around it.

[0025] In this example, the curved support block 7 is preferably made of an elastic material.

[0026] Specifically, it reduces the compression rigidity on both sides of the packaging bag, mimicking the friction of the packaging bag when it contains food.

[0027] like Figures 1 to 3As shown, during the test, the positions of several grippers 6 are adjusted so that they clamp the edge of the packaging bag. Then, the arc support block 7 is lowered to push the center of the packaging bag downward and tighten it so that the surface of the packaging bag contacts the friction surface 4 on the friction table 3. Then, the mounting frame 5 moves back and forth so that the packaging bag can be subjected to friction test on the friction surface 4.

[0028] Specifically, after the packaging bag is rubbed on one of the friction surfaces 4, a new packaging bag can be taken out and clamped, and then the support 2 can be moved so that the convex surface of the packaging bag is aligned with a different friction surface 4, and the friction test can be carried out again. Different friction surfaces 4 can make the friction test of the packaging bag closer to real life, and the test data is more effective.
