Description

Continuous cutting device

Technical Field

The invention relates to a continuous novel cutting device, belongs to the field of vegetable processing, and particularly belongs to the field of automatic processing and slitting of columnar vegetables.

Background

The radish is common food in daily life of people, and can supplement nutrition required by daily life of people. The slicing and airing of the radishes are an indispensable link in the whole processing and production process of the radishes.

The cutting strips of small batches of radishes, such as single growers, are mainly fixed by manually tensioning square grid cutters or ductile wires, and the cutting strips of the radishes are completed once or twice by manually acting on the grid cutters or the cutting strips. The cutting mode can realize the rectangular-square-shaped radish strip cutting. The main problems are that the labor intensity is high, the labor efficiency is low, and meanwhile, the danger is relatively high, and the method belongs to a rough radish strip cutting mode.

The problem of slitting in the radish processing process is brought to attention of vegetable processing equipment manufacturers, and manpower and material resources are input to develop a plurality of special equipment. One scheme is that the manual work is replaced by motor or hydraulic drive, and the turnip is pushed to act on the grid knife for processing; the other proposal is that a plurality of groups of rotary blades which are arranged circumferentially are adopted to directly cut the radish. According to the two schemes, the radish can be split into strips under the condition of manual cooperation, but the strip cutting form has a certain influence on the subsequent processing link of the radish, and particularly the airing and air-drying link after the radish strip cutting is realized. The split radish strips can be dried in the air in a tiling mode, and the air drying mode which is almost in a two-dimensional plane can not only cause low use efficiency of a drying field, but also influence the radish strips, such as long drying time period, low efficiency, non-uniformity and the like. Compared with a split type slitting mode, the traditional manual slitting mode comprises the following steps of: the advantage of the rectangular strip is prominent.

The proposal adopted by the processing equipment is that grid knives are improved, vertical (transverse) direction is split, and transverse (vertical) direction is rectangular, namely, rectangular and square radish is realized by controlling intermittent action of a blade set in a certain direction. The main disadvantages of retrofit devices currently exist: 1. on one hand, the whole processing flow is intermittent, manual high-strength cooperation is needed, and the processing efficiency is low; 2. the requirement on feeding the radish is high in the processing process, for example, the radish needs to be cut off and cannot be overlong, so that the brittle fracture of the end face of the radish in the pushing and pressing process is avoided; the requirements on the radish end surfaces are high, and the front end surface and the rear end surface need to be in good contact with the pushing action surface and the grid knife surface, so that radish deflection even sliding out and the like in the pushing process are avoided. The problems cause that the modified slitting equipment cannot meet the market demands, especially the demands of mass radish production and processing.

In addition, all adopt the mode of reciprocal promotion in the present slitting equipment, promote the turnip that needs processing and cutter effect, accomplish the cutting. The rigid pushing mode is easy to cause the problems of overlarge local stress, unstable processing process, uncontrollable processing and the like. For example, radish breakage, excessive water discharge during processing, equipment pollution, etc.

Aiming at the problems, the invention provides a continuous strip cutting device, which adopts static friction force as driving force to act on a cutter for processing, and the whole process is in flexible contact, so that the rectangular strip cutting can be realized, the time of the whole processing process can be continuous, the requirement of manual cooperation is greatly reduced, and the processing efficiency is improved.
