3results about How to "Small weight deviation" patented technology

The invention relates to the technical field of food packaging equipment, in particular to a double-channel blanking weighing mechanism which comprises a rack, a hopper and a weighing sensor, a first channel and a second channel are arranged at the top of the rack, feeding mesh belts are arranged in the first channel and the second channel, a detachable limiting stop block is further arranged in the second channel, and the hopper is arranged in the limiting stop block. The hopper is further internally provided with a horizontally-telescopic inserting plate, the hopper can form an opening and closing conducting structure through the inserting plate, the inserting plate is movably connected with the weight measuring sensor through a horizontal moving assembly, materials can be fed into the hopper in a large range in the first channel, the split charging gram weight is made to be close to the critical value or below, and the split charging gram weight is made to be smaller than the critical value. And then continuous single material transportation is carried out through the second channel until the gram weight enters the tolerance range, the alternate blanking effect of large-range blanking and small-range blanking can be achieved, the characteristic of small gram weight deviation is achieved, and precise control over the gram weight of the blueberries in the weighing and packaging link is facilitated.

A method is provided to arrange multiple food slices (m) in such a way that at least a portion of them overlap each other to form an assembly (M) of food slices (m). In this method, the number of food slices (m) forming each assembly (M) and the spacing (K) between the food slices (m) are automatically changed to control the weight of each assembly (M) within a predetermined allowable range, and the total length of each assembly (M) is formed to a set length (A). Furthermore, the number of food slices (m) forming each assembly (M) and the spacing (K) between the food slices (m) are automatically changed according to the length (A) in the arrangement direction of the food slices (m).

The invention discloses an automatic control method and system for tobacco shred winnowing of a cigarette making and plug assembling machine. The method comprises the steps that stem slivers are removed from tobacco shreds through the tobacco shred winnowing system by means of airflow; the cut stem separating system is used for dispersing and conveying the rejected stem slivers; performing visual identification on the slivers and the tobacco shreds which are conveyed in a dispersed manner through a sliver and tobacco shred visual identification system so as to identify the tobacco shreds and the slivers; the weight of the identified tobacco shreds and the stem slivers is metered by adopting a machine vision target detection algorithm through a stem sliver rejected object weight visual metering module; and the cut stem winnowing system and the cut stem separating system are adjusted according to the metering result of the rejected stem weight visual metering module. According to the cut stem winnowing automatic control method and system for the cigarette making and plug assembling machine, the separation effect of cut stems and cut tobacco can be adjusted in real time, the real-time performance and accuracy of cut tobacco content control in the cut stems are improved, the cigarette puncturing defect is reduced, cut tobacco waste is reduced, manual intervention is reduced, and the automation and informatization level of equipment is improved.
