S1, under the action of the output end of a first driving motor 502, a driven wheel 505 and a rotating frame 501 are driven to integrally rotate, so that a rotating disc 510 is not located right above a heating plate 208, the heating plate 208 is taken as a printing table surface, the heating plate 208 is in an inactive state, a printing device 101 is used for forming a plastic product at the top of the heating plate 208, in the 3D printing process, when one-step printing is completed, the printing device 101 is reset, the first driving motor 502 is driven to drive the rotating disc 510 to be located right above the heating plate 208, then the output end of a third stepping motor 509 is used for driving a third screw 506 to rotate, the rotating disc 510 is driven to a position which is matched with the height of each step of printing of the plastic product, the output end of a second driving motor 511 is used for driving a driving gear 512 to rotate, the rotating disc 510 and a plurality of groups of second cooling fans 514 are integrally rotated, and 3D printing of each step is cooled and formed until the plastic product is printed, so that the firmness of the plastic product is improved, and the forming quality is improved;
S2, after the plastic product is molded, the output end of the third stepping motor 509 drives the third screw rod 506 to rotate, so that the rotating disc 510 moves downwards, and the plastic product is located at the height of the rotating disc 510, and because the plastic product is generally in a special shape during production, the clamping mechanism 6 is arranged in an adaptive manner, the output end of the third driving motor 608 drives the driving gear 604 to rotate, so that the external teeth 603, the rotating ring 601 and the internal teeth 602 integrally rotate, all rubber pads 609 are driven to synchronously move towards the position close to the center of the circle of the fixed ring 606, the plastic product is clamped and fixed, the friction force of the contact surface is increased by the rubber pads 609, and the clamping mechanism 6 inside the rotating disc 510 can be driven to integrally rotate through the output end of the second driving motor 511, so that the clamping point of the plastic product can be conveniently and well found, and through the arrangement, the plastic product with different heights and special shapes can be clamped;
S3, because the bottom of the plastic product is adhered to the top of the heating plate 208 after the plastic product is molded, in order to achieve better demolding, the heating plate 208 is started to reach a certain temperature threshold value, and then the plastic product in a clamping state moves upwards under the action of the output end of the third stepping motor 509 to be separated from the heating plate 208, at the moment, partial plastic raw materials are adhered to the top of the heating plate 208, and the bottom of the plastic product is uneven;
S4, stretching the output end of the first electric push rod 102 to drive two groups of first cooling fans 103 to move rightwards, wherein the two groups of first cooling fans 103 face the bottom of a plastic product and the top of a heating plate 208 respectively, and cooling and solidifying the two groups of first cooling fans again;
S5, afterwards, the output end of the first electric push rod 102 drives two groups of first cooling fans 103 to reset, the output end of the transmission motor 204 drives the rotating rod 202 and the tooth piece 203 to integrally rotate, the rack 205 moves rightwards, the movable frame 206 moves rightwards, the connecting arm 207 rotates due to the arrangement of the L-shaped groove 210, the connecting rod 211 slides in the L-shaped groove 210, the heating plate 208 firstly moves linearly and is separated from the square hole 104 formed in the top of the machine body 1, the rear heating plate 208 moves rightwards, the top of the heating plate 208 and the bottom of the first scraper 213 are positioned on the same straight line, so that the first scraper 213 automatically scrapes the solidified plastic at the top of the heating plate 208, the solidified plastic is not adhered to the knife edge of the first scraper 213, and the scraped solidified plastic directly falls into the collecting box 105;
S6, when the plastic is solidified at the top of the heating plate 208, the first stepping motor 305 is started, the movable block 304 and the guide box 308 integrally move to the left side to the center of the square hole 104, the output end of the second electric push rod 306 is extended, the lifting part 307 and the guide box 308 are driven to integrally move upwards, the bottom of the plastic product is located in the guide box 308, in the qualified production height threshold of the plastic product, the bottom of the plastic product is matched with the knife edge height of the second scraper 403, the output end of the third electric push rod 310 is extended, the sleeve 309 is driven to move downwards, the bottom of the sleeve 309 passes through the square hole 104, the output end of the second stepping motor 404 is driven to rotate the second screw rod 401, the second scraper 403 moves left and right, the bottom of the plastic product is scraped, the scraped solidified plastic can not splash out of the guide box 308, and then falls into the collection box 105 to be collected for subsequent 3D printing, waste of the plastic raw material is prevented, the production efficiency of the plastic product is improved due to the step of solidifying the top of the plastic product is synchronous with the removal 208, the production efficiency of the plastic product is also improved, the production efficiency of the plastic product is not smooth, the product is not met, and the quality of the product is met, and the whole production requirements are met.
The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made therein without departing from the spirit and scope of the invention, which is defined by the appended claims.
