1, control principle
As shown in Figure 1; in cocoon drying process; adopt automatic control means; by material detect, speed detects and temperature detection; feeding machine speed, conveyer belt speed, heating using microwave power, far infrared light wave heating power are controlled; to obtaining best cocoon drying effect, and when there are abnormal conditions, protect cocoon drying device not damage.
Whether 1.1 materials detect: at cocoon drier material inlet place, detect and have silk cocoon to enter heating bin.If any silk cocoon, enter, normal heating; As do not have silk cocoon to enter, close the heating power source of corresponding bin, to protect heating element heater and to save the energy.
1.2 speed detect: in cocoon drying process, detect the speed of service of silk cocoon conveyer belt, and adjust the rate of feeding of feeding machine and the speed of conveyer belt is synchronizeed, make that feeding procedure is smooth and easy, silk cocoon can not be out of shape because being squeezed.
The speed detecting step of the present embodiment is: after conveyer belt motor M 90 starts; PLC (M1); from frequency converter M9, read the actual motion speed V1 of conveyer belt motor M 90; then to feeding motor frequency converter M10, send enabled instruction and start feeding machine motor M 100, reading the actual motion speed V2 of feeding machine motor M 100 simultaneously; In M1 inside, compare computing and adjust the speed value of feeding motor frequency converter M10: as V2 ﹥ V1 reduces the speed value of feeding motor frequency converter M10, as V2 ﹤ V1 strengthens the speed value of feeding motor frequency converter M10, as V2 ﹦ V1 keeps the speed value of feeding motor frequency converter M10 constant, make V2 follow the tracks of all the time V1, keep synchronous.
1.3 temperature detection: detect in real time the temperature of silk cocoon in storehouse in heating bin, as the foundation of adjusting microwave or far red light wave power, make under the prerequisite that guarantees flash baking neither can be because of over-heat inside quick-fried pupa, can not stick with paste because surface is overheated cocoon yet.
The step that the present embodiment is controlled temperature has: first by examination, dry, obtain the quick-fried pupa temperature T 1 of different cultivars silk cocoon and stick with paste cocoon temperature T 2, these examinations are dried to data and insert in the database of man-machine interface M3.Before cocoon drying, by the selected cocoon drying data of menu interface of man-machine interface M3, man-machine interface M3 is sent to PLC (M1) by cocoon drying data.During cocoon drying, the silk cocoon temperature T that PLC (M1) measures each heating using microwave bin by temperature detecting module M4, controls: when T1-5 ℃ of T ﹥, reduce the heating using microwave power of this bin as follows; When T1-8 ℃ of T ﹤, strengthen the heating using microwave power of this bin; When T1-5 ℃ of T1-8 ℃ of ﹤ T ﹤, keep the heating using microwave power of this bin.During cocoon drying, the silk cocoon temperature T that M1 measures each far infrared light wave heating bin by temperature detecting module M4, controls: when T2-5 ℃ of T ﹥, reduce the far infrared light wave heating power of this bin as follows; When T2-8 ℃ of T ﹤, strengthen the far infrared light wave heating power of this bin; When T2-5 ℃ of T1-8 ℃ of ﹤ T ﹤, keep the far infrared light wave heating power of this bin.So can guarantee in cocoon drying process, silk cocoon neither can be because of over-heat inside quick-fried pupa, can not stick with paste because surface is overheated cocoon yet.
1.4 abnormal protections: cocoon drying device is in running, during the abnormal conditions such as machinery is stuck, external power source abnormal as occurred, internal component excess Temperature, out of service immediately, and shows fault alarm information.
