[0033] Working principle of each mechanism:

[0034] Feeding chamber 1: It is arranged at the upper end of the detection chamber 7 and is communicated with the detection chamber 7, and is used for receiving and preliminarily processing the raw materials to be detected. A feeding port 2 is provided at the upper end of the feeding chamber 1. An angle adjustment mechanism is arranged inside, including an electric telescopic rod 4 and a blanking plate 3, which are used for adjusting the blanking speed and angle to ensure that the raw materials enter the detection chamber 1 evenly. A flow rate sensor 5 is provided at the blanking port, which monitors the flow rate of the raw materials in real time and is connected to the controller.

[0035] Detection chamber 7: A viscosity detection mechanism and a water filtering and weighing mechanism are arranged up and down inside. The viscosity detection mechanism drives the stirring blade 10 to rotate through a rotating motor 8 and measures the viscosity of the raw materials in cooperation with a viscometer 6; at the same time, the flow direction of the raw materials is controlled through a first weighing sensor 12 and an electric gate on the partition plate 11. The water filtering and weighing mechanism separates water by using a filter screen 19 and a water filtering tank 14, drives a pressing plate 18 to press the raw materials through two telescopic motors 16 respectively, and measures the dry weight in combination with a second weighing sensor 20, so as to calculate the moisture content of the raw materials.

[0036] Collection chamber 23: It is arranged outside the detection chamber 7 and is communicated with the detection chamber 7 through a drain pipe 21, and collects the waste water generated during the detection process. A water collection tank 25 and a third weighing sensor 24 are provided in the collection chamber 23, which are used for further analyzing the composition and total amount of the waste water.

[0037] Controller: As the center of the whole system, it receives the data of each sensor and controls the actions of each actuator to realize the automatic control of the detection process.

[0038] Working process:

[0039] I. Raw material feeding stage

[0040] Raw material input: The raw materials for corrugated board production to be detected are put in through the feed inlet 2 of the feed chamber 1.

[0041] Preliminary treatment: The raw materials are adjusted in the feed chamber 1 by the angle adjustment mechanism (including the electric telescopic rod 4 and the blanking plate 3) to ensure that the raw materials enter the detection chamber 7 evenly at an appropriate speed and angle.

[0042] Flow rate monitoring: The flow rate sensor 5 at the lower end of the feed chamber 1 monitors the flow rate of the raw materials in real time and transmits the data to the controller, so that the controller can adjust the blanking speed and angle according to the flow rate.

[0043] II. Viscosity detection stage

[0044] Stirring and mixing: The viscosity detection mechanism in the detection chamber 7 is started, and the rotation motor 8 drives the rotating shaft 9 to rotate, driving the stirring blades 10 to fully stir and mix the raw materials.

[0045] Viscosity measurement: During the stirring process, the detection end of the viscometer 6 extends into the raw materials to measure the viscosity value of the raw materials in real time and transmits the data to the controller.

[0046] Quality control: The controller judges whether the viscosity of the raw materials meets the standard requirements according to the viscosity value. If not, an alarm is issued or the subsequent process parameters are adjusted.

[0047] III. Water filtration and weighing stage

[0048] Water separation: The raw materials after viscosity detection fall into the water filtration tank 14, and the water is separated from the solid raw materials through the filter screen 19.

[0049] Compaction and weighing: Two telescopic motors 16 drive two pressing plates 18 to move towards each other in the water filtration tank 14 respectively to compact the solid raw materials. At the same time, the weighing sensor II 20 measures the dry weight of the raw materials after compaction.

[0050] Water content calculation: The controller calculates the water content of the raw materials according to the dry weight and the original weight of the raw materials and compares it with the standard value.

[0051] IV. Wastewater collection stage

[0052] Wastewater discharge: The wastewater generated during the detection process is discharged into the collection chamber 23 through the drain pipe 21.

[0053] Wastewater treatment: The water collection tank 25 in the collection chamber 23 collects the wastewater, and the weighing sensor III 24 measures the total amount of the wastewater. The wastewater can be further treated or discharged as needed.

[0054] V. Data recording and feedback

[0055] Data recording: The controller records key data such as viscosity values and moisture contents obtained during the detection process and generates a detection report.

[0056] Feedback adjustment: According to the detection results, the controller can automatically or manually adjust subsequent production process parameters to ensure the stability of product quality.

[0057] VI. Maintenance and servicing

[0058] Regular inspection: Regularly inspect and maintain the detection device to ensure the normal operation and accuracy of each component.

[0059] Cleaning and maintenance: Regularly clean components such as the filter screen 19 and the filter water tank 14 to prevent blockage and contamination.

[0060] Calibration adjustment: Regularly calibrate and adjust measuring elements such as sensors to ensure the accuracy of measurement results.

[0061] This device can achieve comprehensive, accurate, and rapid detection of the raw materials for corrugated cardboard production, providing a strong guarantee for producing high-quality products.
