Problems solved by technology

[0005] To this end, the embodiment of the present invention provides an online sampling device for gypsum board and its detection method. The online sampling device is used to automatically raise the gypsum board sample and transfer, and the next group of gypsum board plates on the production line continue to pass through the space below the online sampling device. Transmission does not affect the automatic operation of the production line, so as to solve the problem in the prior art that the gypsum board is broken due to sampling, which affects the accuracy of the sampling result and easily causes sampling errors

Embodiment 1

[0039] like figure 1 As shown, the present invention provides an online sampling device for gypsum board. The online sampling device of this embodiment is applied to a production line for continuous transmission of gypsum board, and mainly includes two parts,

[0040]The first part is the online sampling function. When sampling gypsum boards, the photoelectric sensor senses the gypsum boards transported above the online sampling device, and the online sampling device automatically rises to transfer the samples of gypsum boards. The plates and plates continue to be transported through the space below the online sampling device, without affecting the automatic operation of the production line, and realizing online sampling.

[0041] The second part is the automatic measurement function, which transfers the gypsum board extracted by the online sampling device to the weighing platform, uses the distance measuring grating to collect the length and width information of the sampled g...

Embodiment 2

[0067] Such as Figure 5 As shown, the present invention also provides a gypsum board online sampling device and sampling detection method, comprising the following steps:

[0068] Step 100: Start the No. 1 conveyor belt and the No. 2 conveyor belt, detect the quantity of the conveyed gypsum boards in real time, raise the sampling mechanism every ration of gypsum boards, and extract the gypsum boards for quality inspection.

[0069] This step uses the method of systematic sampling to carry out online sampling on the gypsum boards on the production line. Each quantitative sample is sampled at intervals of a certain number, and one or several samples are randomly selected from a section of numbered products with the same interval, thereby improving sampling detection. Accuracy of realization of certified quality cases.

[0070] This step mainly uses the photoelectric sensor installed at the end of the No. 1 conveyor belt to detect the number of gypsum boards to be transported. ...

Abstract

The embodiment of the present invention discloses an online sampling device for gypsum board, which includes the No. 1 conveyor belt and the No. 2 conveyor belt which are close to each other. The gypsum boards are transferred to the No. 2 conveyor belt through the lifting sampling mechanism. The lifting sampling mechanism performs online sampling detection every quantitative gypsum board. , extract the gypsum boards for quality inspection; transfer the extracted gypsum boards, and check whether the weight and length and width information of the gypsum boards are normal; the next group of gypsum boards on the No. Conveyor belt conveying; the online sampling device of this scheme automatically rises to transfer the gypsum board samples, and the next group of gypsum board plates on the production line continues to be transported through the space below the online sampling device, without affecting the automatic operation of the production line.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of gypsum board production line, in particular to an online sampling device for gypsum board and a detection method thereof. Background technique [0002] Gypsum board is a material made of building gypsum as the main raw material. It is a building material with light weight, high strength, thin thickness, convenient processing, sound insulation, heat insulation and fire resistance. It is one of the new lightweight panels that are currently being developed. The gypsum boards produced in my country mainly include paper gypsum boards, decorative gypsum boards, gypsum hollow slats, fiber gypsum boards, gypsum sound-absorbing boards and anchor point gypsum boards. [0003] In the existing gypsum board industry, the sampling of gypsum board and the monitoring after sampling are all manual monitoring. There are different errors in the monitoring of different personnel. During the samplin...
