The reduction gearbox 203 is composed of a primary reduction gear 210, a secondary reduction gear 208, and a power gear 211.

During operation, the winding speed can be collected by the third speed encoder 304 and transmitted to the intelligent control mechanism 4 for closed-loop control; the high-speed camera 206 transmits the real-time form of the product in the form of a video stream to the intelligent control mechanism 4 for image recognition and parameter adjustment control. In this embodiment, the spring connecting rib 308 rotates with the second rotating shaft 309 as the center of the circle.

The human-machine interaction interface includes finished product preview, product process parameter settings, product real-time form, system settings and equipment calibration, etc. In addition, processing parameters can also be programmed to perform single parameter processing and variable parameter processing.

[0065] like Figure 7 As shown, the intelligent control mechanism 4 is a microcomputer system with a single board computer as the core, which is used to manage and control the operation of the entire system; the human-computer interaction interface is an important way for the operator to interact with the equipment, such as Fig. 9As shown, basic production conditions such as real-time running time can be seen on the touch screen. In addition, the production process can be set up and the equipment can be set up, such as parameter adjustment equipment calibration.

The single-board computer system 401 in the intelligent control mechanism 4 is equipped with a Linux operating system, and the relevant interfaces provided by the Linux system are used to complete the docking with the hardware driver. Due to the high-speed transportation of raw materials during the startup process, in order to capture the state under high-speed operation, the camera needs to use an industrial-grade high-speed camera 206.

[0066] The core layer feeding mechanism 1, the core layer feeding and forming mechanism 2 and the winding mechanism 3 are arranged in sequence from bottom to top, and the intelligent control mechanism 4 is installed on a bracket on the side of the power mechanism away from the core layer feeding mechanism 1, the core layer feeding and forming mechanism 2 and the winding mechanism 3.

[0067] Embodiment 2

[0068] like Fig.10 As shown, the present invention further discloses a method for processing a spiral cored product based on single board computer control, and the processing is performed using the spiral cored product processing device based on single board computer control, comprising the following steps:

[0069] Step 1: Install the core layer raw material 201 at a corresponding position on the reduction gear box 203 of the core layer feeding and forming mechanism 2;

[0070] Step 2: After confirming that there is no foreign matter on the feeding roller 101 of the core layer feeding mechanism 1, the core layer raw material 103 is placed on top, and the material head of the core layer raw material 103 is pulled through the guide tube 207 of the core layer feeding and forming mechanism 2 and wound on the product winding drum 306 of the winding mechanism 3, so as to facilitate the smooth reception of the subsequent finished product;

When the tension of the core layer raw material 103 stabilizes and reaches a preset value, the second drive motor 202 of the core layer feeding and forming mechanism 2 starts production according to the preset parameters;

[0073] Step 5: During the manufacturing process, the real-time form of the finished product collected by the high-speed camera 206 and the collected values ​​of the encoders of each mechanism are transmitted to the intelligent control mechanism 4 for automatic adjustment and control, so as to ensure the quality of the product and the safety of personnel and equipment when external interference or internal failure occurs;

[0074] Step 6: If a mechanical failure or other man-made accident occurs during the processing, the machine can be stopped by pressing the emergency stop button 403.

[0075] Furthermore, in step 2, the feeding method of the core layer feeding mechanism 1 is to drive the feeding by relying on the friction force generated by the direct contact between the core layer raw material 103 itself and the first feeding roller 101 and the second feeding roller 102. The three are in direct contact and have the same rotation linear speed, thereby avoiding the influence of the feeding speed caused by the smaller radius of the core layer raw material 103 package as the feeding continues, and improving the accuracy through mechanical means.

[0076] Furthermore, in step 4, the control algorithm of the intelligent control mechanism 4 is implemented by a cascade PID controller, the process parameters are used as the input values ​​of the outer loop, the real-time process parameters obtained by the image recognition algorithm are used as the feedback values ​​of the outer loop, the output value of the outer loop PID controller is used as the input value of the inner loop PID controller, and the real-time motor speed returned by the encoder is used as the feedback value, and finally the processing of the predetermined process parameters is completed by real-time control of the motor speed. Specifically, Figure 8 As shown, the cascade PID control method is used to improve the stability and accuracy of product processing. After the operator sets the processing parameters through the touch screen 402 and starts the machine, the preset process parameters are used as the input values ​​of the outer loop PID controller, the high-speed camera 206 obtains the product form in real time, and transmits the video to the single-board computer system 401. The built-in automatic control program extracts the video image as a picture according to the video frame rate, and obtains the actual process parameters of the product as the feedback value through edge recognition analysis. The output value after the PID controller is used as the input value of the inner loop PID controller, and the acquisition value of each mechanism encoder is used as the feedback value of the inner loop PID. After the inner loop PID controller, the real-time speed value of the motor is output, and finally the stable and accurate control of the product process parameters is achieved. The specific parameters of the above PID controller need to be debugged and corrected according to the specific equipment. In addition, the parameters of the PID controller can also be modified and debugged in a small range by the debugger through the human-computer interaction interface to make the equipment reach the best state.

[0077] Furthermore, in step 5, the real-time form of the finished product captured by the high-speed camera 206 is captured as a picture according to the video frame rate, and then image recognition of the finished product is performed to calculate the real-time product process parameters, and the control algorithm programmed in the single-board computer system 401 compares the real-time process parameters with the preset parameters to obtain real-time adjustment instructions to adjust the real-time rotation speeds of the first drive motor 104, the second drive motor 202 and the third drive motor 302. The image recognition is mainly achieved through the following three steps: first, the captured picture is binarized, and then the binarized image is filtered to remove noise, and finally, the edge recognition method is used to obtain the various process parameters of the core-wrapped finished product and output them to the control algorithm unit for control.
