[0001] The invention relates to the technical field of artificial wood floor packaging production, and more specifically to an artificial wood floor detection and packaging device. Background Art

[0002] With the continuous advancement of science and technology, in the process of artificial wood flooring production, in order to ensure, the artificial wood flooring needs to be packaged. In order to ensure the transportation of artificial wood flooring, the pass rate of artificial wood flooring packaging production needs to be improved. Artificial wood flooring detection and packaging equipment is needed to perform compression detection on the artificial wood flooring packaging. The whole process requires the use of artificial wood flooring detection and packaging equipment. Artificial wood flooring detection and packaging equipment is a device that detects the artificial wood flooring packaging results during the artificial wood flooring packaging production process. The artificial wood flooring detection and packaging equipment is mainly composed of a shell component, a connection component, a power component and a detection component. The artificial wood flooring detection and packaging equipment has the advantages of fast detection speed and good detection effect.

[0003] Common equipment used for testing and packaging artificial wood floors generally has the following defects during use:

[0004] First, during the use of common artificial wood floor inspection and packaging equipment, during the inspection process, the power source is generally used to provide power for comprehensive inspection of the artificial wood floor packaging. During the inspection process, it is necessary to inspect along the artificial wood floor packaging and to compact the results at a single position of the artificial wood floor packaging, which consumes a lot of power and reduces the efficiency of artificial wood floor packaging inspection;

[0005] Second, when the common artificial wood floor testing and packaging equipment is in use, when the artificial wood floor packaging has a compression structure that does not meet the standards, it will only display the structural results, and cannot re-compress the artificial wood floor packaging, which is not conducive to the compression test of the artificial wood floor packaging and reduces the qualified rate of artificial wood floor packaging production;

It is not possible to display and mark the unqualified artificial wood flooring packaging, which is not conducive to the subsequent testing and repair of the artificial wood flooring packaging, and is not conducive to the production and manufacturing of artificial wood flooring packaging;

[0007] To sum up: the common artificial wood floor inspection and packaging equipment has the defects of not only needing to inspect along the artificial wood floor packaging, but also needing to inspect the compression result at a single position of the artificial wood floor packaging during use, which consumes a lot of power, and can only display the structural results, but cannot re-compact the artificial wood floor packaging and cannot display and mark the unqualified parts of the artificial wood floor packaging, which is not conducive to the subsequent inspection and repair of the artificial wood floor packaging.

The top of the moving groove 2 is rotatably connected to the threaded rod 802, and the side wall of the pressing plate 706 is fixedly connected to a lifting block 803. The lower end of the threaded rod 802 penetrates the lifting block 803 and is threadedly connected to the lifting block 803. A plurality of extrusion rods 804 are fixedly connected to the lower surface of the pressing plate 706. The top of the moving groove 2 is rotatably connected to the rotating rod 805, and the rotating rod 805 and the threaded rod 802 are connected through a transmission wheel group 806. The lower end of the rotating rod 805 penetrates the pressing plate 706 and is sleeved with a second gear 810. The upper surface of the moving block 708 is rotatably connected to a support rod 807, and the outer wall of the support rod 807 and the outer wall of the rotating rod 801 are both sleeved with a bevel gear group 809, and the outer wall of the support rod 807 is sleeved with a first gear 808.

The motor 702 drives the power rod 703 to rotate, and the power rod 703 drives the transmission rod 704 to rotate through the sprocket and the chain 705, so that the moving plate 707 drives the bottom plate 5 to move, and under the action of the connecting rod 710, the moving block 708 moves together with the testing plate 6, so that different positions of the artificial wood floor packaging can be tested. At the same time, the sliding block 711 drives the pressing plate 706 to move together, so that the pressing plate 706 is always directly above the testing plate 6, and only one power source is needed to realize the testing of different positions of the artificial wood floor packaging;

[0048] When there is a defect in the artificial wood floor packaging, the artificial wood floor packaging will push the detection plate 6 to move up, and the detection plate 6 will drive the support rod 807 to move up together, so that the bevel gear set 809 is meshed, the first gear 808 is meshed with the second gear 810, and the spring 709 is stretched. Since a sprocket is also sleeved on the outer wall of one end of the rotating rod 801, the sprocket cooperates with the chain 705, and the rotating rod 801 drives the support rod 807 to rotate, so that the support rod 807 drives the rotating rod 805 to rotate. Under the action of the transmission wheel set 806, the threaded rod 802 rotates, and the lifting block 803 drives the pressing plate 706 to descend and presses the detection plate 6 through the squeezing rod 804, so as to achieve the purpose of pressing the artificial wood floor packaging. Only one power source is needed to achieve this, which is simple and convenient.
