[0044] Working principle and use process of this device: In order to clearly describe the working principle of the present invention, we use Figure 1 The perspective is explained as follows: S1. First, under the action of the output end of the first driving motor 502, the driven wheel 505 and the rotating frame 501 are driven to rotate as a whole, so that the rotating disk 510 is not located directly above the heating plate 208, and the heating plate 208 is used as the printing table. The heating plate 208 is in an inactive state, and the printing device 101 performs molding of the plastic product on the top of the heating plate 208. In the process of 3D printing, each step of printing is completed, and the printing device 101 is reset, and then the first driving motor 502 is driven to make the rotating disk 510 located directly above the heating plate 208. Then, the output end of the third stepping motor 509 drives the third screw rod 506 to rotate, so that the rotating disk 510 moves to a height-matched position with each step of printing of the plastic product. The output end of the second driving motor 511 drives the driving gear 512 to rotate, and drives the rotating disk 510 and a plurality of groups of second cooling fans 514 to rotate as a whole, and each step of the 3D printing is cooled and molded until the plastic product is printed. In this way, the firmness of the plastic product is improved and the molding quality is improved; S2. After the plastic product is formed, the output end of the third stepper motor 509 drives the third screw rod 506 to rotate, so that the rotating disk 510 moves downward, and the plastic product is located at the height of the rotating disk 510. Since the shape of the plastic product is usually irregular during production, the present invention is adapted to set a clamping mechanism 6, and the output end of the third drive motor 608 drives the active gear 604 to rotate, so that the outer teeth 603, the rotating circle 601 and the inner teeth 602 rotate as a whole, and then drives all the rubber pads 609 to move synchronously toward the center of the fixed circle 606 to clamp and fix the plastic product. The rubber pad 609 increases the friction of the contact surface, and can also rotate through the output end of the second drive motor 511, driving the rotating disk 510 and the clamping mechanism 6 inside the rotating disk 510 to rotate as a whole, so as to better find the clamping point of the plastic product. Through this setting, it is possible to clamp plastic products of different heights and irregular shapes; S3. After the plastic product is formed, its bottom is bonded to the top of the heating plate 208. In order to better demould, the heating plate 208 is started to reach a certain temperature threshold, and then the plastic product in the clamped state moves upward under the action of the output end of the third stepper motor 509 to separate from the heating plate 208. At this time, part of the plastic raw material is usually bonded to the top of the heating plate 208, and the bottom of the plastic product will appear uneven and bumpy. S4, the output end of the first electric push rod 102 is extended, driving the two groups of first cooling fans 103 to move rightward, and the two groups of first cooling fans 103 are respectively directed toward the bottom of the plastic product and the top of the heating plate 208, and the two are cooled and solidified again; S5. After that, the output end of the first electric push rod 102 drives the two groups of first cooling fans 103 to reset, and the output end of the transmission motor 204 drives the rotating rod 202 and the gear 203 to rotate as a whole, and then the rack 205 moves to the right, so that the movable frame 206 moves to the right. Due to the L-shaped groove 210, the connecting arm 207 rotates, and the connecting rod 211 slides inside the L-shaped groove 210, so that the heating plate 208 first moves linearly out of the square hole 104 opened on the top of the body 1, and then the heating plate 208 moves horizontally to the right. The top of the heating plate 208 and the bottom of the first scraper 213 are located on the same straight line, so that the first scraper 213 automatically scrapes off the solidified plastic on the top of the heating plate 208, and the solidified plastic will not adhere to the blade of the first scraper 213, and the scraped solidified plastic directly falls into the collection box 105; S6. While removing the solidified plastic on the top of the heating plate 208, start the first stepper motor 305, so that the movable block 304 and the material guide box 308 move to the left as a whole to the center of the square hole 104. Then, the output end of the second electric push rod 306 extends, driving the lifting member 307 and the material guide box 308 to move upward as a whole. The bottom of the plastic product is located inside the material guide box 308, and within the qualified production height threshold of the plastic product, the bottom of the plastic product is matched with the blade height of the second scraper 403. Then, the output end of the third electric push rod 310 extends, driving the kit 309 to move downward, and the bottom of the kit 309 passes through the square hole 104. The output end of the second stepper motor 404 drives the second screw rod 401 to rotate, so that the second scraper 403 moves left and right to scrape the bottom of the plastic product. The scraped solidified plastic will not splash out from the material guide box 308, but will fall into the collection box 105 for collection, and will be used for subsequent melting of the raw materials to prepare for future 3D printing, thereby preventing the waste of plastic raw materials. Since it is carried out simultaneously with the step of removing the solidified plastic on the top of the heating plate 208, the production efficiency of the plastic products is improved, and the unevenness of the bottom of the plastic products is avoided, thereby improving the qualified rate of the products. The whole process is automated to meet the needs of the staff.
