Description

Technical Field

[0001] The utility model relates to the technical field of corrugated cardboards, in particular to a device for detecting defective corrugated cardboards. Background Art

[0002] Corrugated cardboard is a multi-layer adhesive body, which is composed of at least a layer of corrugated core paper and a layer of cardboard on each side. The corrugated corrugations of the corrugated cardboard are like connected arches, arranged in a row and supporting each other to form a triangular structure. It has high mechanical strength and can withstand collisions and falls during transportation. Therefore, the compressive strength of the corrugated cardboard needs to be tested after production to ensure that the compressive strength of the corrugated cardboard meets the requirements of use.

[0003] To this end, the China Patent Network has published a corrugated cardboard production inspection device, with publication number CN115200978A. The device comprises a side frame and a receiving frame, wherein the receiving frame is mounted on the side frame, and the end surface where the receiving frame connects to the side frame is provided with a downward slot, and the receiving frame is provided with a detection mechanism for performing compression testing on the corrugated cardboard. The present invention clamps and fixes the corrugated cardboard using tooth plates on the upper and lower sides, so that impurities attached to the surface of the corrugated cardboard can fall downward, while also preventing the corrugated cardboard from moving when the cleaning mechanism cleans the surface of the corrugated cardboard, thereby affecting its cleaning effect. The cleaning mechanism uses a scraping and suction method to clean the corrugated cardboard, thereby improving the cleaning effect of the corrugated cardboard surface, preventing some impurities from remaining on the surface of the corrugated cardboard from affecting the accuracy of the compression testing of the corrugated cardboard, and also avoiding the problem of impurities on the corrugated cardboard being scattered and affecting the environment.

[0004] The existing device clamps and fixes the corrugated cardboard through two tooth plates when testing it, and squeezes the corrugated cardboard through a push plate to test the strength of the corrugated cardboard. However, the corrugated cardboard cannot be positioned during the testing process, and the center position of the corrugated cardboard cannot be squeezed when squeezing the corrugated cardboard, resulting in errors in the test results and affecting the accuracy of the corrugated cardboard compression test. Therefore, a defective corrugated cardboard detection device is proposed. Utility Model Content

[0037] Example 2

[0038] like Figure 1-Figure 5 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the detection mechanism 2 includes a fixed frame 201, the bottom surface of the fixed frame 201 is fixedly connected to the top surface of the base plate 1, a lifting plate 206 is fixedly provided on the inner rear end surface of the fixed frame 201, a pressure detector 204 is fixedly provided on the bottom surface of the lifting plate 206, a pressure block 203 is fixedly provided on the bottom surface of the output end of the pressure detector 204, an electric push rod 202 is fixedly provided on the top surface of the fixed frame 201, the bottom surface of the output end of the electric push rod 202 passes through the top surface of the fixed frame 201 and extends to the inner side of the fixed frame 201, the bottom surface of the output end of the electric push rod 202 is fixedly connected to the top surface of the lifting plate 206, a limiting rod 205 is fixedly provided on the top surface of the lifting plate 206, the top surface of the limiting rod 205 passes through the inner top surface of the fixed frame 201 and extends to above the fixed frame 201, and a conveyor belt 3 is fixedly provided on the top surface of the base plate 1.

[0039] In this embodiment, the strength of the corrugated cardboard can be tested by providing a detection mechanism 2. By controlling the downward movement of the pressing block 203, the bottom surface of the pressing block 203 contacts the top surface of the corrugated cardboard.

During the test, the pressure on the corrugated cardboard can be observed by the pressure detector 204, making the test result more accurate.

[0040] When in use, place the corrugated cardboard on the conveyor belt 3, turn on the conveyor belt 3 to transport the corrugated cardboard, and after being transported to the left side of the conveyor belt 3, it will fall on the fixed frame 401. After the corrugated cardboard falls on the fixed frame 401, it will squeeze the lifting block 411. After being squeezed, the lifting block 411 will move downward. When the lifting block 411 moves downward, it can drive the pressing block 416 to move downward synchronously. When the pressing block 416 moves downward, it can squeeze the two sliding blocks 417, causing the two sliding blocks 417 to move forward.

When the lifting plate 206 moves downward, it can drive the pressure detector 204 to move synchronously. When the force detector 204 moves downward, the bottom surface of the pressing block 203 can contact the top surface of the corrugated cardboard, thereby performing pressure testing on the corrugated cardboard. After the corrugated cardboard is tested, it is removed. After the corrugated cardboard is removed, the lower pressing block 416 can be moved upward by the elastic member 418. After the lower pressing block 416 moves upward, it can be separated from the two sliding blocks 417. The connecting block 422 can be moved downward by the two elastic sheets 424. When the two connecting blocks 422 move downward, the two sliding blocks 417 can be brought closer to each other.
