Abstract
The present invention relates to a kind of wood pulp feed control method, comprise the following steps: the first step, calculate the amount of feeding of wood pulp, and calculate board wood pulp feed speed and ratio of board speed in the range of different speeds of production, make wood pulp feed speed follow board velocity variations；Second step, arranges wood pulp grammes per square metre, and the speed of board is divided into multiple velocity shooting, is separately provided wood pulp charging rate coefficient between each velocity shooting；3rd step, the initial value of given wood pulp charging coefficient, runs board, weighs the grammes per square metre of wood pulp at each velocity shooting respectively, according to product wood pulp grammes per square metre requirement, adjust the wood pulp feeding coefficient of each velocity shooting, it is ensured that wood pulp grammes per square metre keeps consistent at each velocity shooting.
Description
Technical field
The present invention relates to a kind of wood pulp feed control method.
Background technology
During sanitary towel, diaper, the manufacturing of mattress, when board operationally, the speed of wood pulp charging motor
Degree becomes fixed proportion to change with speed of production, owing to entire volume wood pulp weight in process of production constantly changes, causes wood
There is certain error in the amount of feeding of slurry, makes the product of production and the certified products of requirement there is error, affect product quality.
Therefore, the method the most generally using speed segmentation, use different ratio controls in different speed of production sections
The speed of wood pulp processed charging motor, reduces the error of the wood pulp amount of feeding.But there are some defects in the method, in two adjacent speed
Between degree section, there is saltus step in the speed of wood pulp feeding motor, as it is shown in figure 1, the amount of feeding of wood pulp is intersegmental in the two speed
There is error in change.
Summary of the invention
The technical problem to be solved in the present invention be to provide a kind of control effective, can effectively reduce saltus step occur, can
Effectively control the wood pulp feed control method of wood pulp feeding.
For reaching above-mentioned purpose, the technical scheme is that a kind of wood pulp feed control method, comprise the following steps:
The first step, calculates the amount of feeding of wood pulp, and calculates board wood pulp feed speed and board in the range of different speeds of production
The ratio of speed, makes wood pulp feed speed follow board velocity variations；
Second step, arranges wood pulp grammes per square metre, and the speed of board is divided into multiple velocity shooting, is separately provided wood between each velocity shooting
Slurry charging rate coefficient；
3rd step, the initial value of given wood pulp charging coefficient, run board, weigh the grammes per square metre of wood pulp at each velocity shooting respectively,
According to product wood pulp grammes per square metre requirement, adjust the wood pulp feeding coefficient of each velocity shooting, it is ensured that wood pulp grammes per square metre is protected at each velocity shooting
Hold consistent.
Technique scheme has the advantages that this wood pulp feed control method is by using continuous print speed to become
Change, reduce the speed difference of adjacent two speed intersegmental wood pulp feed speed, thus improve product quality, rate of reducing the number of rejects and seconds, joint
About production cost.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of existing wood pulp feed speed change；
Fig. 2 is the flow chart of the present invention；
Fig. 3 is the schematic diagram of the wood pulp feed speed change of the present invention.
Detailed description of the invention
With specific embodiment, the present invention is described in further detail below in conjunction with the accompanying drawings.
With reference to Fig. 2, Fig. 3, the present embodiment provides a kind of wood pulp feed control method, comprises the following steps: the first step, calculates
Go out the amount of feeding of wood pulp, and calculate board wood pulp feed speed and ratio of board speed in the range of different speeds of production,
Wood pulp feed speed is made to follow board velocity variations；
Second step, arranges wood pulp grammes per square metre, and the speed of board is divided into multiple velocity shooting, is separately provided wood between each velocity shooting
Slurry charging rate coefficient；
3rd step, the initial value of given wood pulp charging coefficient, run board, weigh the grammes per square metre of wood pulp at each velocity shooting respectively,
According to product wood pulp grammes per square metre requirement, adjust the wood pulp feeding coefficient of each velocity shooting, it is ensured that wood pulp grammes per square metre is protected at each velocity shooting
Hold consistent.
This wood pulp feed control method, by using continuous print velocity variations, reduces adjacent two the intersegmental wood pulp of speed and enters
To the speed difference of speed, thus improve product quality, rate of reducing the number of rejects and seconds, save production cost.
Below being only one preferred embodiment of the present invention, those skilled in the art is made the change being equal to by claim
Both fall within the protection domain of this case.
