Description

Automatic coarse crushing process for traditional Chinese medicine materials with different material sizes Technical Field The invention relates to the technical field of general crushing, in particular to an automatic coarse crushing process for traditional Chinese medicine materials with different material sizes. Background The traditional Chinese medicine materials are generally subjected to coarse crushing treatment before production of the preparation, so that the bulk or strip-shaped medicinal materials are crushed into granules suitable for subsequent crushing, extraction or granulation. Because the sources of the traditional Chinese medicinal materials are wide, the differences of the shapes, the sizes and the structures of the traditional Chinese medicinal materials are obvious, and the original materials with different sizes and different shapes often exist in the same production batch. In the traditional Chinese medicine production enterprises, the coarse crushing process mostly depends on general coarse crushing equipment, and the material crushing operation is completed by setting a fixed feeding mode and a fixed crushing rotating speed. The equipment has mature structure and strong adaptability, is widely applied to the links of processing of traditional Chinese medicine decoction pieces and pretreatment of traditional Chinese medicine preparations, and plays an important role in ensuring basic production capacity and continuous operation. The prior art has the problems that in the prior coarse crushing process of traditional Chinese medicine materials aiming at different material sizes, the crushing parameters are usually set by relying on manual experience, and the crushing parameters are kept relatively fixed in the crushing process. However, since the size distribution of the initial particles of the traditional Chinese medicine is not constant, when the initial material particles are large and the setting of the crushing rotating speed or feeding speed is unreasonable, the problems of overlarge instantaneous load, insufficient crushing, accumulation of materials in a crushing cavity and the like easily occur, the crushing stability is affected, and the treatment efficiency or stability is difficult to balance. In actual production, more fibers exist in part of traditional Chinese medicine materials, and materials with strong fiber properties are easy to extrude, adhere or agglomerate in the coarse crushing process, so that part of strip-shaped medicinal material particles cannot be effectively crushed and are directly discharged from a discharge port, and the sizes of the obtained medicinal material particles are uneven and the crushing effect is fluctuated. The problems are difficult to find and effectively respond in time in the traditional coarse crushing process by manually adjusting parameters, and particularly, unstable coarse crushing quality is more easily caused under the conditions of different initial particle sizes and stronger fibers, so that the requirements of automatic and continuous production are difficult to meet. Disclosure of Invention The invention provides an automatic coarse crushing process for traditional Chinese medicine materials with different material sizes, which aims to solve the existing problems. The automatic coarse crushing process for the traditional Chinese medicine materials with different material sizes adopts the following technical scheme: the embodiment of the invention provides an automatic coarse crushing process for traditional Chinese medicine materials with different material sizes, which comprises the following steps: After the operation of the coarse crushing device is started, acquiring a feeding medicinal material image, a discharging medicinal material image and a feeding speed at each sampling time; Dividing a plurality of feeding medicinal material particle areas from a feeding medicinal material image at the current sampling time, and acquiring a reference rotating speed and a reference feeding speed in the next parameter adjustment after the current sampling time according to the area difference among the feeding medicinal material particle areas and combining the minimum rotating speed, the maximum rotating speed, the minimum feeding speed and the maximum feeding speed of the coarse crushing device; Dividing a discharged medicinal material image at each sampling time into a discharged medicinal material region and a discharged background region, and dividing a plurality of discharged medicinal material particle regions from the discharged medicinal material region; according to the area difference between the areas of the discharged medicinal material particles at the current sampling time, combining the difference of the area ratio of the discharged medicinal material areas at different sampling times corresponding to the same feeding speed to the discharged background area, and acquiring a crushing abnormal factor at the current
