Description

It is a kind of for making the 3D printer of dietary fiber thin pancake

Technical field

It is specially a kind of for making the 3D printing of dietary fiber thin pancake the present invention relates to dietary fiber food preparation field Machine.

Background technique

Dietary fiber plays the role of the digestion and excretion solid waste that promote enteron aisle very important, and appropriately supplement is fine Dimension element can make the food increase in enteron aisle soften, intestines peristalsis is promoted to prevent constipation and reduction to accelerate defecation speed The risk of intestinal cancer, cellulose can also adjust blood glucose, help prevention diabetes, and can reduce absorption of the digestion process to fat, To play the role of reducing the level of Blood Cholesterol, triglyceride, hypertension, cardiovascular and cerebrovascular disease are prevented and treated；

Coarse food grain thin pancake is fiber diet that is a kind of common and being liked by the numerous people masses, and the production of traditional thin pancake is will to adjust The paste made is spread out in by hand on the griddle heated, makes trouble efficiency and low, due to being high-temperature operation, long-time operation is very It is arduous, and shape is more traditional, and unsightly, has developed a kind of pancake-baking machine of 3D printing in the prior art, passes through 3D technology Draw the pattern of thin pancake, it is convenient and efficient and can arbitrarily make oneself desired thin pancake shape, but 3D printing now is decocted Thin pancake can not be made yield by cake machine, it is desirable to which multiple equipment must be needed while run by printing multiple thin pancakes, and when printing When pattern is excessively complicated, thin pancake manufacturing speed just be will be greatly reduced, this is because existing thin pancake printer is to use Stepper motor drives shift gear of the structure of ball-screw as nozzle, although ball-screw transmission efficiency is high, precision Height, low noise be suitble to the round-trip transmission of high speed, but span is big when horizontal conveyor will consider limit speed and sagging change of being self-possessed Shape, so drive length can not be too big, on long range heavy duty linear motion, it is inadequate that screw rod is possible to intensity, will lead to Loom occur vibration, shake situations such as, it is serious, will lead to screw rod bending, deformation, even fracture etc., this result in using When lateral displacement transmission device of the ball-screw as nozzle, receiving load capacity cannot be excessive, and it is all that displacement cannot be too long etc. More limitations.
