Description

Computer Control Method of Intelligent Bamboo Board Forming Press Machine

technical field

The invention relates to a control method of an automatic control device, in particular to a computer control method for an intelligent bamboo board forming punching machine.

Background technique

With the rapid development of the social economy, people have higher and higher requirements for home environmental protection. Bamboo flooring is more and more popular among the people because of its environmental protection, firmness and stability, smoothness and softness. At present, in the stamping process of bamboo, due to the uneven carbonization degree of bamboo silk raw materials, the imbalance of manual weighing and charging, and the uneven moisture content of bamboo silk raw materials, it is difficult to determine the pressure value of the hot press only by operator experience. and the quality of the bamboo board after stamping, resulting in the thickness of the bamboo floor, uneven color, and even cracking, etc., the product quality is difficult to guarantee, and the defective rate is high, which has caused huge economic losses to the production enterprise. Promotion is limited.

The thickness of the bamboo board is an important indicator of the quality of the bamboo board. There is also a close relationship between the water content of the bamboo board and the color of the bamboo board. There is no strict way to judge whether the bamboo board is qualified, and it can only be judged based on experience.

Contents of the invention

The purpose of the present invention is to provide a computer control method for an intelligent bamboo board forming punching machine, which can automatically detect the thickness, color and moisture content of the bamboo board after punching, and can automatically judge the quality of the bamboo board after punching. Control Method.

The control device of the bamboo board forming stamping machine proposed by the present invention is composed of a microcontroller, a moisture detection circuit, an ultrasonic distance measuring circuit, a pressure detection circuit, a color recognition sensor, a display circuit and a relay, and the microcontroller receives the moisture detection circuit and the ultrasonic distance measuring circuit. 1. The color of the pressure detection circuit recognizes the signal of the sensor, outputs the signal to the display circuit for display, and sends the processed signal to the relay to control the start and stop of the punching machine. The microcontroller weights and sums the signals of each sensor and detection circuit to To judge whether the stamped bamboo board is qualified, the power supply circuit provides power to the microcontroller and relay.

The working process of the present invention is as follows: first put the pressed bamboo shreds into the hot pressing mold, start the hot press and start pressing down, the microcontroller starts the ultrasonic ranging circuit to emit ultrasonic signals, and the microcontroller reads the pressure of the pressure detection circuit in real time The signal and the ultrasonic ranging circuit receive the ultrasonic signal, the color signal of the color recognition sensor and the moisture signal of the moisture detection circuit. When the real-time pressure value reaches the qualified pressure value of the set bamboo board, the microcontroller brake relay cuts off the power supply of the punching machine, and the punching machine stops. After the control device of the heavy bamboo board punching machine automatically stops the punching machine, the microcontroller reads the distance signal from the upper surface of the reorganized bamboo board after punching to the ultrasonic transceiver probe detected by the ultrasonic distance measuring circuit, and sends the distance signal from the lower surface of the reorganized bamboo board to the ultrasonic transceiver probe. The fixed value of the distance is subtracted from the distance from the upper surface of the reorganized bamboo board detected by the ultrasonic ranging circuit to the ultrasonic transceiver probe to obtain the thickness of the reorganized bamboo board after stamping.

The raw material, bamboo shreds, is carbonized bamboo shreds, which are divided into three categories according to the water content, namely, the first type of material with a low water content, less than 3%, and the second type of material with a water content of 3-10%. , and the third type of materials with a water content higher than 10%. The different water content of bamboo silk is caused by the uneven temperature in the carbonization process and the different water content of the raw materials. It is difficult to achieve the purpose of uniformity. Because the bamboo pressboard has a process of water loss in the natural environment before leaving the factory, the requirements for the outer material require a relatively high moisture content, and for the color, the water content is relatively high, because it is carbonized at a lower temperature, the color is lighter . The feeding process is completed by multiple feedings according to the thickness. The first type of material with the least water content is added at the beginning, divided into three layers, staggered at 45 degrees, and needled in the vertical direction, accounting for more than 70% of the total material. When the thickness is detected When it is less than the set value of 7-12mm, add the second type of material with medium water content. When the detected thickness is less than the set value of 3-6mm, add the second type of material with medium water content and high water content at a ratio of 1:1. The third type of material, when the detected thickness is less than 1-2 mm of the set value, add the third type of material with high water content, and when the detected thickness is less than 1 mm of the set value, the product is directly obtained. Due to the high pressure of the stamping mold, too many times of feeding will affect the processing efficiency, and the obtained products can be divided into many categories according to the water content, color and thickness.

The microcontroller calculates the weighted sum D of the thickness signal h of the bamboo board detected by the ultrasonic ranging circuit, the water content signal s of the bamboo board of the moisture detection circuit, and the carbonized color signal y of the bamboo board detected by the color recognition sensor according to (1) formula . The following formula is calculated based on long-term data:

The microcontroller judges the quality of the stamped bamboo board according to the weighted value D of each sensor and detection circuit signal. If D is less than or equal to 0.6, it means that the stamped bamboo board is qualified; if D is greater than 0.6, it means that the stamped bamboo board is unqualified and needs to be re- Stuffing stamping. When D is less than 0.6 and S is less than 1200, pack it directly; when D is less than 0.6 and 1250>S>1200, store it for 7-10 days; for packaging.

The invention is easy to use, can automatically stop the punching machine, can automatically detect the thickness, color and water content of the punched bamboo board, can automatically judge the quality of the punched bamboo board, and can reduce repeated punching during the punching and forming process of the recombined bamboo and improve the quality of the finished product It has a good effect in reducing the waste of bamboo shreds, because the classification of raw materials in the carbonization process simplifies the carbonization control process, reduces the temperature control requirements of the carbonization process, and saves energy loss and raw materials caused by the carbonization process. Loss, improve the production efficiency of bamboo press board.
