[0035] It should be noted that the gear-shaped block 4141 is only a 30° arc-shaped block of the gear block, and only allows the flat plate block 4111 to rotate an angle in the range of 0~20, and the two flat plate groups 41 are each provided with one limiting component 414, the limiting component 414 is provided to prevent the angle of the flat plate block 4111 from being too large, so that the workpiece falls to the outer side of the moving plate 43, and the flat plate block 4111 is better reset, and the platform formed by the whole flat plate block 4111 is more stable.

[0036] Referring to the drawings accompanying the specification Figure 7 The auxiliary structure 42 comprises an auxiliary plate 421, the auxiliary plate 421 is provided with two, the two auxiliary plates 421 are slidably connected with a top block 422, and the two auxiliary plates 421 are fixedly connected with a hollow block 423 near one side of the moving plate 43.

[0037] It should be noted that the auxiliary plate 421 is provided in an L shape, so that the flat plate block 4111 can be rotated, thereby facilitating the flat plate block 4111 to pry the printed product.

[0038] Referring to the drawings accompanying the specification Figures 1-2 The printing structure 3 comprises an extrusion device 31 provided in the interior of the casing 2, the interior of the casing 2 is provided with an X-axis module 32, a Y-axis module 33 and a Z-axis module 34, and the moving end of the Z-axis module 34 is provided with a support plate 35.

[0039] It should be noted that the three-axis module is conducive to the printing of the extrusion device 31, and the extrusion device 31 adopts a PLA extrusion mechanism or a carbon fiber extrusion mechanism. The PLA extrusion mechanism is a "low-cost, general-purpose thermoplastic material extrusion device", and the core is around the low melting point and easy melting characteristics of PLA. It pursues simplicity and reliability, and convenient operation. The carbon fiber extrusion mechanism is a "high-precision, high-cost composite material forming device", and the core is around the high hardness and high wear resistance characteristics of carbon fiber. It solves the three major pain points of "non-broken conveying, uniform mixing, and part wear resistance" to realize the continuous production of high-strength formed parts.

[0042] In this embodiment, the specific implementation scenario is as follows: when the staff prints the 3D product, the product is printed in the center of the platform composed of the whole flat block 4111 and the auxiliary structure 42. First, the required printing material is sent into the extrusion device 31, then the shell cover 21 is covered, the touch screen device outside the shell 2 is started, the corresponding product is selected, the extrusion device 31 is moved through the X-axis module 32, the Y-axis module 33 and the Z-axis module 34 to cooperate with the platform composed of the flat block 4111 in the platform structure 4 to print the product. When the product is printed and needs to be taken out, the motor 4121 of the first flat group 41 is started at this time, the rotating rod 4122 is rotated by the motor 4121, the gear two 4123 is rotated by the rotating rod 4122, the gear one 4114 is rotated by the gear two 4123, the rotating rod one 4113 is rotated by the gear one 4114, the connecting block 4112 is rotated by the rotating rod one 4113, the flat block 4111 is lifted by the connecting block 4112. At this time, the gear one 4114 is rotated and the gear three 4131 is also rotated, the gear one 4114 of the other flat block 4111 is rotated by the gear three 4131, thereby driving the four flat blocks of the first flat group 41 to slightly lift, then the flat block 4111 close to the product is slowly separated from the product, then the motor 4121 is started in the opposite direction, thereby resetting the flat block 4111, then the motor 4121 of the second flat group 41 is started, and the flat block 4111 of the second flat group 41 is separated from the product. In this way, the whole product is separated from the flat block 4111, and then the staff can take out the flat block 4111. When the flat block 4111 rotates, in order to accurately reset the first flat group 41 and the second flat group 41, when the motor 4121 lifts the flat block 4111 closest to the auxiliary structure 42, the gear one 4114 of the flat block 4111 rotates the gear-shaped block 4141, the gear-shaped block 4141 is clamped by the L-shaped block 4143 when it rotates, thereby controlling the opening angle of the flat block 4111, and stably resetting the flat block 4111.

[0043] The accompanying drawings are referred to in the description of the application Figures 7-8 Since the product is printed in the center of the platform composed of the whole flat block 4111 and the auxiliary structure 42, when the diameter of the 3D printed workpiece is smaller than the auxiliary structure 42, the flat block 4111 does not work at this time, and the staff cannot lift the product.

[0044] To solve this problem, the following technical solutions are also provided: the hollow block 423 is internally provided with a lifting structure 424, the lifting structure 424 comprises a hydraulic rod 4241, the hydraulic rod 4241 is fixedly connected to the side of the moving plate 43 away from the flat plate block 4111, the output end of the hydraulic rod 4241 is fixedly connected with a circular plate 4242, the side of the circular plate 4242 away from the hydraulic rod 4241 is fixedly connected with a moving rod 4243, and the side of the moving rod 4243 away from the circular plate 4242 is fixedly connected with the top block 422.

[0045] Further, the side of the auxiliary plate 421 close to the top block 422 is provided with a sliding groove 4211, and the side of the top block 422 close to the auxiliary plate 421 is fixedly connected with a sliding block 4221.

[0046] Still further, the sliding block 4221 is arranged in the corresponding sliding groove 4211, and the sliding block 4221 and the auxiliary plate 421 are in sliding connection.

[0047] It should be noted that the auxiliary plate 421 is provided in an L shape, and the two auxiliary plates 421 are symmetrical about the top block 422.

[0048] In this embodiment, the implementation scenario is specifically as follows: when the workpiece is printed on the plane composed of the two auxiliary plates 421 and the top block 422, the hydraulic rod 4241 is started at this time, the hydraulic rod 4241 moves with the circular plate 4242, the circular plate 4242 moves with the moving rod 4243, the moving rod 4243 moves with the top block 422, and the top block 422 directly separates the product from the two auxiliary plates 421, wherein the top block 422 moves with the sliding block 4221 in the sliding groove 4211, so that the top block 422 is better reset, and then the product is adhered to the outside of the top block 422, because the overall volume of the top block 422 is small, at this time, the worker can directly take away the product by opening the shell cover 21.

[0049] Working principle: I. The worker first fills the material into the extrusion equipment 31, and then starts the touch screen device to print the product, at this time, the printing structure 3 directly prints on the platform structure 4.

[0050] II. After the product is completed, if the product is between the flat plate block 4111 and the auxiliary structure 42, at this time, the driving part 412 is started to rotate with the rotating part 411 and the driven part 413, so that the flat plate block 4111 is separated from the product, and the two groups of flat plate groups 41 are the same, and at the same time, the connection between the product and the auxiliary structure 42 is also separated.

[0051] III. If the product is only on the outside of the auxiliary plate 421 and the top block 422 of the auxiliary structure 42, at this time, the lifting structure 424 is directly started to separate the product from the auxiliary plate 421.

[0052] The above embodiments only express several implementation manners of the present application, which are described in a more specific and detailed manner, but cannot be understood as a limitation on the patent scope of the present application. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, which all belong to the protection scope of the present application.
