Powder metering tube (18), liquid material hopper (11) and load-bearing plate (12) thereof and electronic scale are the proportioning dress Put building block, mixer (13) is powder liquid material evenly mixing device, and motor (15) is the power of mixer (13) The source, magnetic valve (9) K1K2 is loaded on respectively on the feed liquor and drain pipe of liquid material hopper (11), and powder is carried Motor (17) is located at the lower end of powder vertical tranporter (19), and electromagnetic switch K4 is loaded on powder and carries motor (17) above, electromagnetic switch (16) K3 is located at powder metering tube exit. Between waiting below the load-bearing plate (12) Apart from establishing 3 weight sensors (1) as this machine weight sensing element, sensor (1) output-parallel enters wiring Input weight transmitter (2) behind the box is by powder hopper (18), load-bearing plate (12), weight sensor (1) And transmitter (2) forms the powder material weighing assembly. Powder amount hopper (18) is supported by vertebra shape load-bearing plate (12) With fixing, sensor (1) bears changes in weight and inputs to weight transmitter (2). By liquid material hopper (11), Load-bearing plate (12), LOAD CELLS (1) and transmitter (2) form the liquid material assembly of weighing. Liquid material hopper (11) fixing by load-bearing plate (12) support. Spaced set is in load-bearing plate (12) between the LOAD CELLS (1) Under. Electronic scale links to each other with the microcomputer cpu bus through A/D converter (3), and gauge tap (9) K1～K4 is logical Crossing digital quantity converter (7) links to each other with the microcomputer cpu bus. Input keyboard (5) adopts digital keys, at need When wanting manual mode operation, accurately easy. Actual proportioning result, simultaneously aobvious with data and curve by display screen Show, show simultaneously in addition, the water content of thin slice on the infrared ray moisture content detector sense transmission line, Guarantee the accurately stable of proportioning.
The control procedure of embodiment is described below in conjunction with accompanying drawing.
Proportioning be with tobacco powder with through 5 processes that prepare liquid material mixing and stirring, if each proportioning is a benchmark with the consumption G of pressed powder, the each consumption M=rG of liquid material then, wherein r is the proportioning coefficient, when giving computer input value G, can calculate and export liquid material consumption.The numerical value of M, G is by electronic scale real-time sampling input computer, and the consumption M of control liquid material reaches in the control thin slice moisture content desired range of values.For example determine that proportionality coefficient r is 0.45～0.50, behind this device proportioning and stirring and evenly mixing, the expectation moisture content that obtains compound is in 33 ± 0.5% scopes.If K4 is logical state, vertical transport motor (17) is in running status, powder is sent into powder hopper (18) from vertical transport pipe (19), electronic scale (1,2) sense restatement amount, if this moment, K1 was for logical, K2 is disconnected state, then the liquid material also adds liquid material hopper (11) electronic scale (1 slowly, 2) sense restatement amount, signal is through A/D conversion input microcomputer, calculating conversion through microcomputer, obtain the weight of powder liquid material, microcomputer is according to software program (shown in Figure 4), judge whether powder weight reaches the upper limit, after reaching the upper limit, microcomputer output D/O digital quantity signal, K4 becomes disconnected by logical through change-over circuit control vertical transport motor switch, and powder stops to enter, meanwhile also judge at any time whether the liquid material reaches the upper limit, after arriving the upper limit, microcomputer is exported to the D/O digital quantity signal, and feed liquor material magnetic valve K1 is closed in control through change-over circuit, after postponing a period of time, open blowing electromagnetic switch K3 and tapping magnetic valve K2, begin to put the powder tapping, electronic scale input weight variable signal is given microcomputer, when detecting powder liquid weight, microcomputer reaches down in limited time, send the signal of telecommunication that has reached ratio requirement respectively and remove to close K2 and K3, send the order of opening K1K4 then, begin the circulation in next cycle.
