3. Advantageous effects
1. The driving mechanism can drive the trough to move left and right on the base when in work, the left trough body on the trough rotates by taking a rotating shaft on the first hinged seat as a circle center under the action of pulling or supporting of the first telescopic mechanism, namely, when the trough moves left, the telescopic mechanism can be stretched, the telescopic mechanism can have a pulling effect on the bottom end of the left trough body, the left trough body rotates anticlockwise by taking the rotating shaft on the first hinged seat as the circle center through the pulling of the telescopic mechanism on the bottom end of the left trough body, the right trough body on the trough still slides horizontally on the base, when the left trough body rotates anticlockwise, the horizontal position of the bottom in the left trough body is lower than the horizontal position of the bottom in the right trough body, and as the right trough body is communicated with the left trough body, the feed liquid in the right trough body can flow to the inside of the left trough body, so that the feed liquid in the right trough body is reduced in height, and when the trough moves right under the driving of the driving mechanism, the left trough body can be horizontally aligned with the right trough body under the pulling of the right trough body, so that a large amount of feed liquid gathered in the left trough body can flow back to the inside of the right trough body, thereby providing a forming condition for printing a product after solidification;
in conclusion, the trough is moved left and right through the driving mechanism in the design application, so that the condensation surface of the product solidified by the light beam is staggered with the feed liquid which is not solidified, the acting force of the solidified product on demoulding from the feed liquid is reduced, the demoulding of the product is convenient, meanwhile, the feed liquid can be continuously accumulated in the left trough body at a low level position, the solidified product can be separated from the feed liquid in the right trough body while being staggered with the feed liquid, the quick demoulding of the solidified product is realized, the feed liquid in the left trough body is continuously accumulated, the condensation surface of the product can be separated from the feed liquid after each solidification, and is immersed in the feed liquid again before the next solidification, so that the condensation surface of the solidified product is prevented from generating empty drum with the feed liquid during the next solidification, and influence the quality of making of product, this kind carries out the setting that reduces through the dislocation between product and the feed liquid and to the feed liquid level, make the product after the light beam solidification produce less effort between with the feed liquid, can also guarantee that the product after solidification at every turn can not appear and the feed liquid between produce the phenomenon of hollowing, thereby the product can be quick deciduate after having guaranteed to print, the quality that the product was printed has still been guaranteed, reduce current product after the light beam solidification, only extract the product after will solidifying from the feed liquid through elevating system, the product that leads to after the solidification produces great effort between easy and the feed liquid when extracting, and cause the pulling to the product after just solidifying, influence the quality of product after the solidification, also influence the deciduate efficiency of product after the solidification simultaneously.
2. According to the invention, the concave rod between the third threaded rod and the fourth threaded rod can be driven to translate on the inner side of the trough through positive and negative rotation of the third threaded rod and the fourth threaded rod, the feed liquid stored in the trough can be spread and scraped through translation of the concave rod, so that the feed liquid in the trough can be spread and leveled before printing each time, a powerful condition is provided for printing of a product, and after the product is printed at one time, the concave rod can move leftwards (the printed product is lifted at the moment), so that the concave rod can shift the feed liquid below a condensation surface of the printed and solidified product, and the demoulding of the product is promoted.
3. The contact switch is arranged, so that the left groove body and the right groove body are horizontally aligned and then simultaneously move rightwards (at the moment, the light-transmitting opening is not aligned with the light-transmitting window, and the feed liquid gathered in the left groove body flows towards the right groove body), the concave rod on the coating and scraping mechanism is driven to move rightwards when the arc-shaped end on the strip-shaped limiting block contacts the contact switch, so that the feed liquid in the horizontally aligned left groove body and right groove body is coated and scraped, and the coating and scraping mechanism is rotationally controlled, so that the feed liquid can be effectively leveled, and the next product curing is facilitated.
4.
