The camera 4 and the display screen 5 make it convenient for people to observe the position of the corrugated paper.

[0052] The advantages of the second embodiment over the first embodiment are:

[0053] 1. The height of the placement plate 2 can be adjusted by rotating the second threaded rod 39 and using the support rod 36 to lift or lower the placement plate 2, thereby facilitating the adjustment of the height of the corrugated paper and enabling the testing of corrugated paper of different heights;

[0054] Second, by setting the limit block 43, when the guide rod 24 is reset, the sliding frame 42 can be pushed upward by the push block 44, so that the corrugated paper is limited by the limit block 43 to prevent the corrugated paper from moving and avoiding people's hand pressing, which is convenient for people to use;

[0055] Third, by using the camera 4 and the display screen 5 in conjunction with each other, people can check the position of the corrugated paper by observing the display screen 5, thereby improving the accuracy of the connection between the corrugated paper and the separation rod 21.

[0056] Working principle: When in use, place the corrugated paper on the placement plate 2, and make one side of the corrugated paper contact the positioning plate 26. Adjust the corrugated paper by observing the situation on the display screen 5. When adjusting, rotate the first threaded rod 29, the first threaded rod 29 drives the first threaded sleeve 32 to rotate, and the first threaded sleeve 32 drives the wedge block 33 to move, and the positioning plate 26 is pushed to move by the wedge block 33. The position of the corrugated paper is fine-tuned through the positioning plate 26. At the same time, when the first threaded rod 29 rotates in the opposite direction, the spring 28 plays a role in pushing the positioning plate 26 to return to its original position.

[0057] After the position is aligned, the second cylinder 16 is started, and the second cylinder 16 drives the first movable plate 17 to move, and the first movable plate 17 drives the second movable plate 20 to move, so that the separation rod 21 is inserted into the corrugated paper. When the guide rod 24 moves, the top block 44 is driven to move, and the top block 44 contacts the sliding frame 42, thereby lifting the sliding frame 42, and the sliding frame 42 drives the limit block 43 to move upward, so as to limit the corrugated paper and prevent the corrugated paper from moving. Then the first cylinder 13 is started, and the first cylinder 13 drives the tension sensor 14 and the pulling plate 15 to move. The pulling plate 15 moves upward through the second guide block 23, the second insertion frame 22 and the second movable plate 20, thereby moving the upper separation rod 21 upward, and the bonding strength of the corrugated paper is judged by the tension sensor 14;

[0058] When the thickness of the corrugated paper is different and different layers are tested, the second threaded rod 39 is rotated, and the second threaded rod 39 pushes the second threaded sleeve 38 to move. The second threaded sleeve 38 pushes the support rod 36 through the two push rods 37, and then the support rod 36 is used to adjust the position of the placement plate 2, thereby making it convenient for people to test corrugated paper of different thicknesses.

[0059] However, as is well known to those skilled in the art, the working principles and wiring methods of the first cylinder 13, the second cylinder 16 and the tension sensor 14 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions, which should all be included in the scope of the claims of the present invention.
