[0001] The utility model relates to the technical field of spinning production, in particular to a spinning production control system. Background Art

[0002] The hot melt spinning machine heats the raw materials through a screw extruder and controls the extrusion pressure to turn them into a hot melt. The hot melt is then measured by a high-precision metering pump for spinning. The spinning is cooled by side blowing and then wound at high speed by a winder.

[0028] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings.

[0029] Reference Figure 1 and Figure 2 The present utility model provides a spinning production control system, including:

[0030] Production execution module 100;

[0031] The frequency conversion module 200 is electrically connected to the production execution module 100;

[0032] A control module 300, electrically connected to the frequency conversion module 200;

[0033] Alarm module 600;

[0034] The monitoring module 400 includes a control chip 410, a monitoring chip 420, a first communication chip 430 and a second communication chip 440. The production execution module 100, the frequency conversion module 200, the control chip 410 and the control module 300 are electrically connected to the first communication chip 430 respectively, the production execution module 100, the frequency conversion module 200, the monitoring chip 420 and the control module 300 are electrically connected to the second communication chip 440 respectively, and the control chip 410 is electrically connected to the monitoring chip 420.

[0035] Based on this, by setting the control module 300 and the frequency conversion module 200, the control module 300 controls the working state of the production execution module 100 through the frequency conversion module 200, so as to ensure that during the spinning production process, the working state of the production execution module 100 always remains consistent, thereby ensuring the stability of the fineness of the spinning in the spinning roll, thereby improving the quality of the spinning roll; by setting the monitoring module 400, the monitoring module 400 includes a control chip 410 and a monitoring chip 420, and the monitoring chip 420 monitors the working state of the production execution module 100. Based on the working state obtained by the monitoring chip 420, the control chip 410 and the control module 300 jointly control the production execution module 100, thereby ensuring the stability of the production execution module 100, reducing the failure rate of the production execution module 100, and also improving the quality of spinning.

[0036] Specifically, the control module 300 is used to send a control signal with a target operating frequency to the frequency conversion module 200, and the frequency conversion module 200 controls the production execution module 100 based on the target operating frequency; the monitoring module 400 is used to receive a feedback signal from the production execution module 100, and the monitoring chip 420 monitors and identifies the feedback signal to obtain the actual working status of the production execution module 100, and the control chip 410 determines to adjust the operating frequency according to the actual working status, and sends a control signal with the adjusted operating frequency to the frequency conversion module 200, thereby adjusting the working status of the production execution module 100.

[0037] It is understandable that the control module 300 controls the operating speed of the production execution module 100 by sending the target operating frequency to the frequency conversion module 200 .

[0038] In a specific embodiment, the spinning production control system also includes a computer, and the control module 300 and the monitoring module 400 are respectively connected to the computer. The computer is used to monitor and control the control information of the control module 300 and the monitoring module 400, thereby monitoring and controlling the working status of the production execution module.

[0039] Reference Figure 3 In certain embodiments of the utility model, the production execution module 100 includes a flow pump 110, a first rotating roller 120 and a second rotating roller 130. The flow pump 110 is used to output the spinning melt to the first rotating roller 120. The first rotating roller 120 is used to stretch the spinning melt to obtain a spinning strip. The second rotating roller 130 is used to wind the spinning strip into a spinning roll.

[0040] Refer again Figure 3 In certain embodiments of the present invention, the frequency conversion module 200 includes a first frequency converter 210, a second frequency converter 220 and a third frequency converter 230, the first frequency converter 210 is electrically connected to the flow pump 110, the second frequency converter 220 is electrically connected to the first rotating roller 120, and the third frequency converter 230 is electrically connected to the second rotating roller 130.

[0041] Specifically, the target operating frequency includes a first operating frequency corresponding to the flow pump 110, a second operating frequency corresponding to the first rotating roller 120, and a third operating frequency corresponding to the second rotating roller 130. The injection frequency of the flow pump 110 is controlled based on the first operating frequency, the first rotational speed of the first rotating roller 120 is controlled based on the second operating frequency, and the second rotational speed of the second rotating roller 130 is controlled based on the third operating frequency.

[0042] In a specific embodiment, the control module 300 sends the target operating frequency to the first inverter 210, the second inverter 220 and the third inverter 230 in turn. When one of the inverters receives a control signal with the target operating frequency, the inverter will send feedback information with the actual operating frequency to the monitoring module 400. After the monitoring module 400 receives the feedback information, the computer will control the control module 300 to send a control signal with the target operating frequency to the next inverter.

[0043] In addition, the monitoring module 400 determines to adjust the operating frequency according to the feedback signal, and the monitoring module 400 sends the adjusted operating frequency to the frequency conversion module 200 , thereby adjusting the working state of the production execution module 100 .

[0044] Specifically, the working state of the production execution module 100 includes the injection frequency of the flow pump 110 , the first rotation speed of the first rotating roller 120 , and the second rotation speed of the second rotating roller 130 .

[0045] In addition, the control module 300 stores the target operating frequency sent each time, and the monitoring module 400 also stores the feedback signal and the adjusted operating frequency received each time, so as to facilitate the staff to query and repair.

[0046] It can be understood that, based on the feedback information received by the monitoring module 400, it can be determined whether the control module 300, the frequency conversion module 200 and the monitoring module 400 can communicate normally. When the communication between the control module 300, the frequency conversion module 200 and the monitoring module 400 is abnormal, the staff can be reminded to perform maintenance in time, thereby improving production efficiency.

[0047] Refer again Figure 1 In some embodiments of the present invention, the monitoring module 400 further includes a third communication chip 450 , and the third communication chip 450 is electrically connected to the control chip 410 , and the third communication chip 450 is also electrically connected to the flow pump 110 .

[0048] In a specific implementation, the first rotating roller 120 and the second rotating roller 130 are electrically connected to the third communication chip 450 , respectively.

[0049] Specifically, the monitoring module 400 obtains the actual injection frequency of the flow pump 110 , the first rotation speed of the first rotating roller 120 , and the second rotation speed of the second rotating roller 130 through the third communication chip 450 .

[0050] Refer again Figure 2 Some embodiments of the present invention further include a first display module 510 , wherein the first display module 510 is electrically connected to the control module 300 , and the first display module 510 is used to display first control information of the control module 300 .

[0051] Specifically, the first display module 510 is disposed in the computer 800 , and the first control information includes a target operating frequency, ie, an injection frequency of the flow pump 110 , a first rotation speed of the first rotating roller 120 , and a second rotation speed of the second rotating roller 130 .

[0052] Refer again Figure 1 In certain embodiments of the present invention, the monitoring module 400 further includes a fourth communication chip 460, and the spinning production control system further includes an alarm module 600, and the alarm module 600 and the monitoring chip 420 are electrically connected to the fourth communication chip 460 respectively.

[0053] Based on this, by setting up the alarm module 600, when the monitoring chip 420 recognizes that the feedback signal is abnormal, or the monitoring chip 420 cannot receive the feedback signal of the control module 300 and the frequency conversion module 200, the control alarm module 600 will alarm, which can prompt the staff to perform maintenance.

[0054] Refer again Figure 2Some embodiments of the present utility model further include a second display module 520, wherein the second display module 520 is electrically connected to the fourth communication chip 460, and the second display module 520 is used to display the second control information of the monitoring module 400.

[0055] Specifically, the second display module 520 is set in the computer 800. The second control information includes the actual operating frequency sent by the frequency conversion module 200 to the monitoring module 400 and the adjusted operating frequency sent by the monitoring module 400 to the frequency conversion module 200. In addition, the second display module 520 also displays the actual injection frequency of the flow pump 110, the first rotation speed of the first rotating roller 120, and the second rotation speed of the second rotating roller 130.

[0056] Based on this, by setting the second display module 520 to display the second control information and the working status of the frequency conversion module and the production execution module 100, it can be convenient for the staff to perform inspection and maintenance.

[0057] Reference Figure 1 In some embodiments of the present invention, the production execution module 100 further includes a fourth frequency converter 140 , and the fourth frequency converter 140 is electrically connected to the first communication chip 430 .

[0058] In a specific embodiment, the fourth frequency converter 140 is also electrically connected to the flow pump 110, and the control chip 410 sends a control signal of the test operating frequency to the fourth frequency converter 140. The fourth frequency converter 140 controls the flow pump 110 to spray at the test operating frequency. At the same time, the monitoring chip 420 obtains the test spray power of the flow pump 110 when it sprays at the test operating frequency.

[0059] Refer again Figure 2 Some embodiments of the present invention further include an instruction input module 700 , and the instruction input module 700 is electrically connected to the control module 300 .

[0060] Specifically, the instruction input module 700 is set in the computer 800, and the staff can input the target fineness of spinning through the instruction input module 700, thereby controlling the production execution module 100 to produce spinning with the target fineness; in addition, the staff can also directly control the target operating frequency of the production execution module 100 through the instruction input module 700, thereby controlling the production execution module 100 to produce at the target operating frequency.

[0061] Refer again Figure 1 In some embodiments of the present invention, the monitoring module 400 further includes a timer 470 , and the timer 470 is electrically connected to the monitoring chip 420 .

[0062] Specifically, the monitoring module 400 obtains the accumulated production time of the production execution module 100 through the timer 470, and can determine the actual length of the spinning in the spinning roll based on the accumulated production time and the actual operation frequency.

[0063] In addition, after obtaining the feedback information of one of the inverters, the monitoring module 400 uses the timer 470 to determine the interval length. When the interval length is equal to one second, if the feedback signal of the next inverter is still not received, the alarm module 600 is controlled to alarm.

[0064] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
