Description
Technical field
The present invention relates to the horizontal defoliator group field in threshing and redrying production line, is a kind ofly to meet that horizontal defoliator group is accurately weighed to supplied materials and the system of sub-material in proportion specifically.
Technical background
At beating and double roasting, beat in leaf production process, the homogeneity of sub-material has significant impact to sheet type structure and the conformability of beating leaf efficiency, getting tobacco leaf of each defoliator.In industry traditional method is mostly to adopt physical construction, the artificial uniform distributing of realizing material of adjusting, this physical construction, the artificial sub-material of adjusting are not adjusted data intuitively, can not carry out at any time on-line control control, be a very extensive master mode; Also there is at present the mode that adopts impact flow meter to weigh, by falling material, the impulsive force feedback electric signal of impact flow meter is judged the size of sub-material, thereby regulate, this mode makes progress than mechanical system, but material drop be very random, same material while dropping the drop point at impact flow meter different, the impact electric signal of generation is all different, measure inaccurately, can not accomplish completely the inhomogeneity control of sub-material.The phenomenon of sub-material inequality, causes the load difference of the several defoliators in front and back and then has affected beating leaf effect, so will guarantee that the blade effect that each defoliator is got unanimously must guarantee the uniform and stable, controlled of sub-material.
Summary of the invention
In view of above-mentioned present situation, the object of this invention is to provide and in a kind of horizontal defoliator group, supplied materials is accurately weighed and the system of sub-material in proportion.In process of production, the weighing in real time to supplied materials by sub-material belt, show intuitively sub-material amount at different levels, according to the cumulant of the front and back belt conveyer scale of a period of time (such as 1 minute) is poor, just can calculates this period of time to fall into the material amount of defoliator how many, thereby calculate accurately the mass flow of sending into defoliator, compare with the sub-material flow of needs, rotating speed and position by the whole poking device of automatic adjusting regulate control to sub-material flow, improve the stability of supplied materials flow and the homogeneity of sub-material, improve and beat leaf efficiency and sheet type structure.
Object of the present invention is achieved through the following technical solutions:
A kind of supplied materials is accurately weighed and the system of sub-material in proportion, feature of the present invention is, comprise the sub-material belt conveyer scale that multi-level is weighed, between two-stage sub-material belt conveyer scale, be provided with poking device, below poking device, be provided with material-falling hopper, below material-falling hopper, be provided with defoliator, be provided with for weighing, adjust the control system of poking device; Wherein, the belt bottom surface of sub-material belt conveyer scale is comprised of transition carrier roller, the roller of weighing, the LOAD CELLS and the electric-control system that are connected with the roller of weighing.
The multistage sub-material belt of the present invention possesses function of weighing, when meeting mass transport, can weigh to supplied materials, by the comparison of weighing of front and back stages sub-material belt, can calculate the first order to the weight of afterbody sub-material belt sub-material, using this as the foundation of controlling poking device rotating speed or position, finally reach the object of accurate control sub-material amount.
Poking device of the present invention is contained between two-stage sub-material belt, by electric control system to each sub-material amount weigh calculating, export control signal more afterwards and adjust material toggling rotating speed or control it on the upper side, move on the lower side by actuating device by variable frequency control.
The present invention's roller of weighing adopts and singly to weigh that roller is weighed or multi weighing roller is weighed.
The present invention, by the comparison of weighing of front and back stages sub-material belt, can carry out proportional distribution by setting required value by material, also can carry out uniform distribution.
Sub-material belt conveyer scale of the present invention is weigher, adopts at present the very mature and stable direct press type pattern of weighing, can with singly weighing roller or multi weighing roller.Sub-material belt conveyer scale can calculate instant flow rate and real-time cumulant accurately.
The invention has the beneficial effects as follows, the effect of poking device is that a material part that upper class sub-material belt conveyer scale is sent here is dialled in material-falling hopper and entered defoliator, and a part drops and carries toward next defoliator at next stage sub-material belt conveyer scale.Poking device adopts frequency control and position to move can control the material amount of dialling in material-falling hopper.Control method is as follows: according to the cumulant difference of certain hour (such as the 3 minutes) first order, second stage sub-material belt conveyer scale, can calculate the inventory that falls into during this period of time defoliator, calculate the average discharge that falls into during this period of time first group of defoliator.
