Description

Technical Field

[0001] This utility model relates to the field of corrugated paper tear testing, specifically to a corrugated paper tear simulation tester. Background Technology

[0002] Corrugated paper, as an important packaging material, plays a vital role in logistics, warehousing, and transportation. Its tear strength is one of the key indicators for measuring the quality of corrugated paper, which is directly related to the safety and stability of packaged products. Therefore, it is particularly important to develop a simulation tester that can accurately and efficiently test the tear strength of corrugated paper.

[0003] Existing corrugated paper tear simulation testers are usually designed based on the pendulum tear method or similar principles. They assess the tear strength by measuring the energy consumed when the pendulum tears the corrugated paper sample. This design principle is mainly applicable to unidirectional tear testing, that is, tearing the corrugated paper along a specific direction. However, in practical applications, corrugated paper may be subjected to tearing forces from different directions. Therefore, unidirectional testing cannot fully reflect its true tear performance, so corresponding improvements are needed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a corrugated paper tear simulation tester, which solves the problem mentioned in the background art that existing corrugated paper tear simulation testers are inconvenient to simulate multi-directional tearing forces during use.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] This utility model provides a corrugated paper tear simulation tester, comprising:

[0007] The transverse tearing assembly includes an electric telescopic rod, a gear, a first toothed plate, and a second toothed plate. The gear is located between and meshes with the two toothed plates. The electric telescopic rod is connected to the first toothed plate and drives the first toothed plate to move, thereby driving the second toothed plate to move through the gear.

[0008] The clamping assembly includes two supports, two movable plates, and two linear modules. The two supports are arranged parallel to each other at a distance along the longitudinal direction. The bottom ends of each movable plate are respectively placed on the two supports. The two linear modules are respectively mounted on the two movable plates. Each linear module is equipped with an electric gripper. Each linear module drives the electric gripper to move in the transverse direction. The two movable plates are respectively connected to a first toothed plate and a second toothed plate.

[0009] Preferably, each movable plate has a guide groove at each end of its bottom surface, and each movable plate is slidably connected to the top of the two supports by the two guide grooves.

[0010] Preferably, the transverse tearing assembly further includes two longitudinally extending guide rails, which are fixedly installed on the side of one of the vertical plates. A first toothed plate is connected to a movable plate, and a second toothed plate is connected to a driven plate. Both the movable plate and the driven plate are connected to sliders. The movable plate and the driven plate are slidably connected to the two guide rails through the sliders. An electric telescopic rod is connected to the movable plate to drive the first toothed plate to move longitudinally.

[0011] Preferably, the linear module includes a support frame and a moving mechanism. The moving mechanism includes a rotary motor, which is located at one end outside the support frame. The output end of the rotary motor is fixed with a one-way lead screw via a coupling. The one-way lead screw is located inside the support frame. A threaded sleeve is connected to the thread of the one-way lead screw. A slide is provided above the support frame. The threaded sleeve is connected to the slide.

[0012] Preferably, guide frames are fixed on both sides of the slide table, and the two guide frames are located on both sides of one of the movable plates. The slide table is slidably connected to the movable plate through the guide frames.

[0013] The corrugated paper tear simulation tester provided by this utility model has adjustable lateral and longitudinal distances between two electric grippers, enabling lateral and longitudinal tearing of corrugated paper.

They are used only for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. The term "connection" in this embodiment, without specific explanation, should be interpreted broadly; it can refer to a direct connection or an indirect connection, a fixed connection or a movable connection.

[0023] like Figures 1 to 6 As shown in the figure, this embodiment discloses a corrugated paper tear simulation tester, including a base plate 1, on which a transverse tearing component and a clamping component are installed.

[0024] The transverse tearing assembly includes an electric telescopic rod 6, a gear 8, a first toothed plate 18, and a second toothed plate 7. The gear 8 is located between and meshes with the two toothed plates. The electric telescopic rod 6 is connected to the first toothed plate 18 and drives the first toothed plate 18 to move, thereby driving the second toothed plate 7 to move through the gear 8.

[0025] The clamping assembly includes two supports 3, two movable plates 9, and two linear modules. The two supports 3 are arranged parallel to each other at longitudinal intervals. The bottom ends of each movable plate 9 are respectively placed on the two supports 3. The two linear modules are respectively mounted on the two movable plates 9, and each linear module is equipped with an electric gripper 15. Each linear module drives the electric gripper 15 to move laterally. The two movable plates 9 are respectively connected to a first toothed plate 18 and a second toothed plate 7. The cross-section of the supports 3 is L-shaped, and a control panel 16 is fixed to one side of one of the supports 3.

[0026] Two spaced-apart uprights 2 are mounted on one end of the top surface of the base plate 1. The upper ends of the two uprights 2 are connected by a top plate 5. An electric telescopic rod 6 is fixedly installed in the space enclosed by the two uprights 2 and the top plate 5. The electric telescopic rod 6 is fixedly connected to the movable plate 4, or hinged. In this embodiment, one end of the electric telescopic rod 6 is connected to a vertical rotating shaft, and a hinge seat is installed on the slide table 11. The rotating shaft and the hinge seat cooperate to realize the movable connection between the electric telescopic rod 6 and the slide table 11.

[0027] The transverse tearing assembly also includes two longitudinally extending guide rails 501, which are fixedly mounted on the side of one of the upright plates 2. A first toothed plate 18 is connected to a movable plate 4, and a second toothed plate 7 is connected to a driven plate 17. Both the movable plate 4 and the driven plate 17 are connected to sliders, which form a sliding connection between the movable plate 4 and the driven plate 17 and the two guide rails 501, respectively. An electric telescopic rod 6 is connected to the movable plate 4 to drive the first toothed plate 18 to move longitudinally. In other embodiments, the two guide rails 501 may also be combined into one guide rail 501.

[0028] The linear module includes a support frame 14 and a moving mechanism 10. The moving mechanism 10 includes a rotary motor 1001, which is located at one end outside the support frame 14. The output end of the rotary motor 1001 is fixed to a one-way lead screw 1002 via a coupling. The one-way lead screw 1002 is located inside the support frame 14. A threaded sleeve block 1003 is connected to the thread of the one-way lead screw 1002. A slide table 11 is provided above the support frame 14. The threaded sleeve block 1003 is connected to the slide table 11. A support plate 12 is fixed on the slide table 11. A connecting plate 13 is connected to the upper end of the support plate 12. An electric chuck 15 is mounted on the connecting plate.

[0029] Preferably, guide frames are fixed on both sides of the slide table 11, with the two guide frames located on both sides of one of the movable plates 9. The slide table 11 and the movable plate 9 are slidably connected through the guide frames. Preferably, each movable plate 9 has a guide groove at each end of its bottom surface, and each movable plate 9 is slidably connected to the top of the two supports 3 through the two guide grooves. In other embodiments, the guiding structure between the movable plate 9 and the support 3 can also adopt other methods. For example, a guide rail 501 is installed on the support 3, and a slider is installed on the bottom of the movable plate 9, with the slider and the guide rail 501 forming a slidable connection.

[0030] When longitudinally tearing corrugated paper, two sets of electric grippers 15 clamp the corrugated paper card to be tested, using the electric grippers 15 to fix and clamp the corrugated paper. The drive motor 1001 drives the one-way screw 1002 to rotate. The one-way screw 1002 engages with the threaded sleeve 1003, causing the threaded sleeve 1003 to move and drive the slide table 11 to move synchronously. During this process, the guide frame on the outside of the slide table 11 slides along the outside of the moving plate 9, providing movement limit guidance for the slide table 11. Then, the two sets of slide tables 11 move in opposite directions, thus performing longitudinal simulated tearing of the corrugated paper, replacing manual tearing. By observing the movement distance of the slide table 11, the tear strength of the corrugated paper can be evaluated to ensure that the corrugated paper can be easily torn during use while maintaining sufficient strength to prevent accidental breakage.

[0031] When tearing the corrugated paper laterally, the electric telescopic rod 6 pushes the movable plate 4 and the first toothed plate 18 to move laterally. At this time, the movable plate 4 slides on the guide rail 501, so that the first toothed plate 18 meshes with the gear 8, and the gear 8 meshes with the second toothed plate 7. The movable plate 4 and the driven plate 17 slide along the guide rail 501, so that the moving plates 9 of the two linear modules move closer and further away from each other, tearing the clamped corrugated paper laterally, simulating manual tearing. The operation is convenient. Later, the tear strength of the corrugated paper is evaluated by observing the movement distance of the movable plate 4 and the driven plate 17.

[0032] Because the relative positions of the two electric grippers can be flexibly adjusted, this corrugated paper tear simulation tester can perform multi-directional tearing of corrugated paper and achieve multi-directional detection of the tear strength of corrugated paper.

[0033] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. These modifications or substitutions do not cause the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model. Therefore, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
