Description

Plant cured tobacco specimen manufacturing device suitable for batch pressing

Technical Field

The invention belongs to the technical field of specimen making instruments, and particularly relates to a plant cured tobacco specimen making device which is simple in structure, simple and convenient to operate and suitable for batch pressing.

Background

The plant leaf specimen is usually used for identifying plants, plays an important role in teaching, scientific research, resource investigation, academic exchange and related industrial production, and is generally prepared by the steps of field collection, pressing, drying and the like. The pressing step is a key link of the whole preparation of the wax leaf specimen, and is directly related to the quality of the specimen, but the problems of high manpower consumption, low efficiency, uneven quality and the like exist at present. For example, in the method for manufacturing a plant leaf specimen proposed in chinese patent (CN 201610837715.1), the plant leaf specimen is mostly manufactured by using absorbent paper or newspaper, corrugated paper and specimen folder, and is bound and pressed by a binding tape, and then is dried and dehydrated. However, when this method is used, the specimens are stacked in stacks because of the large number, different shapes and sizes, large height after stacking (usually over 50 cm), and easy lateral dumping, and thus the method has a problem of low efficiency. At least one or two persons are required to hold the specimen while binding the specimen. When pressing the specimen, at least one or two persons are needed to press the bundled specimen downwards by manpower, and simultaneously, one person tightens the strapping tape. In the whole pressing process, the manual operation is mainly used for completion, the adapter device is lacked for auxiliary operation, and the problems of small working space, large labor consumption and poor specimen quality exist. Therefore, a new device is invented to solve the above problems. Referring to the relevant literature, for example, chinese patent (CN 201811051789.8), the pressing device for plant specimen proposed in this patent enables the pressed fresh plant specimen to be formed more smoothly and with guaranteed quality, but the device is not suitable for pressing batch plant specimens.

In a word, looking up the related literature data disclosed at present, a device suitable for pressing a newly collected plant in batches for making a cured leaf specimen is not found. Therefore, it is necessary to invent a novel device for simply and efficiently pressing a sample to prevent the sample from toppling over, reduce manpower and material resources, and improve the preparation efficiency and quality of a cured leaf sample.
