Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, a 3D printer includes a body 1 and a platform 2, the inside fixedly connected with platform 2 of body 1, the inside of platform 2 is provided with a heating mechanism 8, the top fixedly connected with printing plate 3 of platform 2, the top fixedly connected with quantity of printing plate 3 is two shells 4, the inside of shells 4 is provided with a displacement mechanism 5, a round bar 6 is fixedly connected between the output ends of two displacement mechanisms 5, and a scraper mechanism 7 is arranged on round bar 6 and located between two shells 4.

Further, in this embodiment, preferably, shell 4 is front and back symmetric distribution, and shell 4 includes casing 41, and a bar groove 42 has been seted up to one side of casing 41, and two bar grooves 42 are used for spacing round bar 6 at the home range of shell 4.

Further, in this embodiment, preferably, as shown in fig. 3, the displacement mechanism 5 includes a stepping motor 51 fixedly connected to the inside of the housing 41, a lead screw 52 movably connected to the inside of the housing 41 is fixedly connected to an output end of the stepping motor 51, a screw thread is provided on an outer side of the lead screw 52 and connected to a screw sleeve 53 through the screw thread, and the two screw sleeves 53 are fixedly connected to the front and rear ends of the round rod 6. The stepper motor 51 during operation drives the lead screw 52 and rotates, nevertheless because two swivel nuts 53 and round bar 6 fixed connection for the circumference of swivel nut 53 rotates limitedly, and can drive round bar 6 and move on the lead screw 52 together, and round bar 6 passes through two bar grooves 42 promptly, and round bar 6 and swivel nut 53 follow lead screw 52 and rotate, and its motion principle adopts lead screw removal principle.

Further, in this embodiment, it is preferable that, as shown in fig. 3, the scraping mechanism 7 includes a ring 71 located outside the round bar 6, a connecting plate 72 is fixedly connected to an outside of the ring 71, a scraping blade 73 is fixedly connected to a side of the connecting plate 72 away from the ring 71, and the scraping blade 73 is used for scraping the printed product off the printing plate 3.

Further, in the present embodiment, it is preferable that a defective product is scraped out in some cases due to loosening of the squeegee or failure to adhere to the printing plate 3 in the process of scraping out. In order to further solve the problem, the scraping mechanism 7 further comprises a torsion spring 74 located on the round rod 6, one end of the torsion spring 74 is fixedly connected with the inside of the round rod 6, the other end of the torsion spring 74 is fixedly connected with the front surface of the ring sleeve 71, and one end of the scraping blade 73 far away from the connecting plate 72 is tightly attached to the top of the printing plate 3. When the torsion spring 74 is in a torsional deformation state, the torsion generated by the torsion spring 74 enables the scraping blade 73 in an indirect connection relation with the ring sleeve 71 to be tightly attached to the top of the printing plate 3, so that seamless connection between the scraping blade 73 and the printing plate 3 is ensured, and the printed products are prevented from being scraped.

Further, in the present embodiment, it is preferable that the scraper and the blade are also closely attached to the printing plate 3 when the printing product which is not easily scraped is touched, but the scraping is difficult due to the viscosity of the raw material. For solving this difficult problem, printing and concentrating and having increased heating mechanism 8, heating mechanism 8 includes and generates heat board 81 with the inside fixedly connected with of platform 2, the top fixedly connected with of board 81 that generates heat and the conducting strip 82 of the laminating of printing plate 3 top, the board 81 that generates heat turns into heat energy transfer for conducting strip 82 with electric energy, conducting strip 82 gives printing plate 3 with heat transfer, printing plate 3 gives the heat transfer and prints the finished product, because it is different with printing plate 3 material to print the finished product, after the heating, both expend with heat and contract with cold the range is different, make the gluing face of printing the finished product and printing plate 3 not hard up, among the prior art has been solved, 3D printer is when using, its finished product after printing is glutinous on the printing table easily, the mode of breaking with the fingers and thumb is usually adopted and thumb is taken off, waste time and energy, and damage the printing finished product easily, lead to the problem that 3D printer is not convenient to use.

The working principle of the invention is as follows:

the first step is as follows: after a printing finished product is formed on the printing plate 3, the heating plate 81 converts electric energy into heat energy to be transmitted to the heat conducting fins 82, the heat conducting fins 82 transmit the heat energy to the printing plate 3, and the printing plate 3 transmits the heat energy to the printing finished product;

the second step is that: the stepping motor 51 drives the screw rod 52 to rotate, so that the threaded sleeve 53 limited by the round rod 6 moves on the screw rod 52, the threaded sleeve 53 drives the round rod 6 to move, the round rod 6 drives the ring sleeve 71 to move, the torsion spring 74 is in a torsional deformation state, the torque generated by the torsion spring 74 enables the scraping blade 73 in indirect connection with the ring sleeve 71 to be tightly attached to the top of the printing plate 3, the ring sleeve 71 drives the connecting plate 72 to move, the connecting plate 72 drives the scraping blade 73 to move, and the scraping blade 73 shovels a printed product from the printing plate 3, so that the purpose of convenience in use is achieved.
