Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0030] In this embodiment, the sampling tube is connected to the packaging machine silo. With the cooperation of the automatic sampling valve and the timing switch, the automatic sampling valve is started at a fixed time to open the sampling tube, so that the alumina powder can enter the sampling bucket in the sampling box along the sampling tube, which improves the sampling efficiency and greatly reduces the labor intensity of the staff.

After the sampling is completed, the sampling bucket can be taken out and sent for testing. The operation is simple and easy to use. The specific implementation is as follows:

[0031] like Figures 1 to 4As shown, an automatic sampling device for powder material packaging includes a sampling tube 2, a sampling box 3 and a timing control component. The sampling tube 2 is connected to one side of the bottom of the packaging machine silo 1. The sampling box 3 is arranged on the ground next to the packaging machine silo 1.

The automatic sampling valve 4 is installed on the outer surface of the sampling tube 2 close to one end of the packaging machine silo 1. A flow meter 7 is arranged on the sampling tube 2 at a position next to the automatic sampling valve 4. The sampling tube 2 is connected to the packaging machine silo 1. With the cooperation of the automatic sampling valve 4 and the timing switch 12, the automatic sampling valve 4 is started at a fixed time to open the sampling tube 2, so that the alumina powder can enter the sampling barrel 13 in the sampling box 3 along the sampling tube 2, thereby improving the sampling efficiency and greatly reducing the labor intensity of the staff. At the same time, a flow meter 7 is also provided on the sampling tube 2 to monitor the sampling amount and realize quantitative sampling, thus avoiding the error caused by manual sampling and ensuring the accuracy of sampling detection. After the sampling is completed, the sampling barrel 13 can be taken out and sent for testing. The operation is simple and easy to use.

[0032] The flowmeter 7 is an electromagnetic flowmeter. The flowmeter 7 and the timing switch 12 are both electrically connected to the automatic sampling valve 4. After the flowmeter 7 detects that a certain amount of aluminum oxide powder has been taken, the automatic sampling valve 4 can be controlled to close the sampling tube 2.

[0033] The feed port of the sampling tube 2 is connected to the packaging machine silo 1, and the discharge port of the sampling tube 2 passes through the middle of the top of the sampling box 3 and is vertically arranged directly above the sampling barrel 13.

[0036] A closed chamber is formed on the inner side of the sampling box 3, in which a sampling barrel 13 is arranged, and an electronic scale 14 is arranged directly below the sampling barrel 13. Through the setting of the sampling box 3, the sampling barrel 13 and the alumina powder sample can be sealed and preserved to avoid the mixing of impurities, thereby improving the detection accuracy.

[0039] A door 5 is hinged on the side wall of the sampling box 3 , and an electronic lock is arranged on the door 5 . The sampling barrel 13 can be quickly taken out by opening the door 5 .

[0040] A fixed bottom plate 6 is provided at the bottom of the sampling box 3, and a plurality of fixing holes 18 are formed on the fixed bottom plate 6. The fixed bottom plate 6 and the fixing holes 18 can facilitate the fixing of the sampling box 3 on the ground, and can avoid shaking and displacement during the sampling process.

[0041] Working principle: The sampling is carried out by connecting the feeding port of the sampling tube to the silo of the packaging machine. A filter is set at the feeding port to block larger particles of alumina powder and avoid clogging the pipeline. With the cooperation of the automatic sampling valve and the timing switch, the automatic sampling valve is started at a fixed time to open the sampling tube, so that the alumina powder can enter the sampling bucket in the sampling box along the sampling tube, which greatly improves the sampling efficiency and reduces the labor intensity of the staff. At the same time, a flow meter is also set on the sampling tube to monitor the sampling volume, which is convenient for quantitative sampling and avoids the errors caused by manual sampling. It ensures the accuracy of sampling and detection. After the sampling is completed, the sampling bucket can be taken out by opening the door of the sampling box and sent to the laboratory for testing. The setting of the sampling box can monitor the sampling bucket and alumina powder. The samples are sealed and stored to avoid the mixing of impurities, which can improve the accuracy of detection. The weight of the samples can be measured by the electronic scale at the bottom, which is convenient for the staff to record and manage. The safety warning structure set on the sampling box can monitor the internal pressure of the sampling tube to avoid damage to the pipeline caused by excessive pressure during the sampling process, further improving the safety of the device. A backup control valve is set on the sampling tube, which can be enabled when the automatic sampling valve fails and cannot be closed. The wear-resistant inner tube set inside the sampling tube can improve its wear resistance and reduce the wear caused by the erosion of alumina powder. The reinforcing casing set outside the sampling tube can improve the strength of the pipeline, making it have better pressure resistance and not easy to break.
