[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-3 This utility model discloses a material unloading platform for a 3D printer, including a base plate 1. Ten mounting mechanisms 2 are evenly arranged on the upper surface of the base plate 1 near the left side. A first driving mechanism 3 is installed on the upper surface of the base plate 1 corresponding to the mounting mechanism 2 near the right side. A platform plate 4 is fixedly installed between the upper surfaces of the left mounting mechanism 2 and the corresponding first driving mechanism 3 on the right side. A prompting mechanism 5 is provided on the lower surface of the platform plate 4 near the left edge. A second driving mechanism 6 is provided on the upper surface of the base plate 1 near both the front and rear. A scraper 7 is fixedly installed between the upper surfaces of the front and rear second driving mechanisms 6.

[0022] Specifically, the installation mechanism 2 includes a column 201 and a first hinge 202. The column 201 is fixedly installed on the upper surface of the base plate 1, and the upper surface of the column 201 is connected to the lower surface of the platform plate 4 through the first hinge 202.

[0023] In this embodiment, the first hinge 202 on the upper surface of the column 201 is used to install the platform plate 4 on the left side of the lower surface, while also enabling the platform plate 4 to rotate.

[0024] Specifically, the first drive mechanism 3 includes a first bearing assembly 301, a first ball screw 302, a first motor 303, a first ball nut 304, a second hinge 305, and a transmission rod 306. The first bearing assembly 301 is installed on the middle and right side of the upper surface of the base plate 1, and the first ball screw 302 is arranged between the first bearing assemblies 301. The left end of the first ball screw 302 is fixedly connected to the output shaft of the first motor 303. The first motor 303 is fixedly installed on the left side of the first bearing assembly 301. The first ball nut 304 is provided on the first ball screw 302. The front and rear sides of the first ball nut 304 and the lower surface of the platform plate 4 are provided with second hinges 305, and the upper and lower second hinges 305 are connected by a feeding mechanism via the transmission rod 306.

[0025] In this embodiment, the output shaft of the first motor 303 drives the first ball screw 302 to rotate in the left and right first bearing assemblies 301. The rotation of the first ball screw 302 causes the first ball nut 304 to move left and right. The first ball nut 304 drives the right end of the platform plate 4 to move up and down through the second hinge 305 and the transmission rod 306.

[0026] Specifically, the outer surface of the first ball nut 304 is rectangular, and the lower surface of the first ball nut 304 is in contact with the upper surface of the base plate 1.

[0027] In this embodiment, the lower surface of the first ball nut 304 moves left and right along the upper surface of the base plate 1 to stabilize the left and right movement of the first ball nut 304.

[0028] Specifically, the prompting mechanism 5 includes a tilt sensor 501, a controller 502, and an alarm 503. The tilt sensor 501 is installed on the left side of the lower surface of the platform plate 4. The tilt sensor 501 is electrically connected to the controller 502. The alarm 503 is installed on the upper surface of the controller 502.

[0029] In this implementation scheme, the tilt sensor 501 monitors whether the platform plate 4 is tilted. When the monitoring causes the platform plate 4 to tilt, the information is fed back to the controller 502. The controller 502 then triggers the alarm 503 to sound an alarm, reminding the staff to carry out maintenance.

[0030] Specifically, the second drive mechanism 6 includes a second bearing assembly 601, a second ball screw 602, a second motor 603, a second ball nut 604, and a support rod 605. The second bearing assembly 601 is installed on the left and right edges of the upper surface of the base plate 1. The second ball screw 602 is arranged between the second bearing assemblies 601, and the left side of the second ball screw 602 is fixedly connected to the right side of the output shaft of the second motor 603. The second motor 603 is installed on the left side of the second bearing assembly 601. The second ball nut 604 is provided on the second ball screw 602. The support rod 605 is fixedly installed on the upper surface of the second ball nut 604, and the upper surface of the support rod 605 is connected to the lower surface of the scraper 7.

[0031] In this embodiment, the output shaft of the second motor 603 drives the second ball screw 602 to rotate within the left and right second bearing assemblies 601. The rotation of the second ball screw 602 drives the second ball nut 604 to move left and right. The second ball nut 604 drives the support rod 605 to move left and right, so that the front and rear support rods 605 synchronously drive the scraper 7 to move left and right. The second motor 603 in the front and rear second drive mechanisms 6 is a synchronous motor.

[0032] Specifically, the outer surface of the second ball nut 604 is rectangular, and the lower surface of the second ball nut 604 is in movable contact with the lower surface of the base plate 1.

[0033] In this embodiment, the lower surface of the second ball nut 604 moves left and right along the upper surface of the base plate 1, so that the left and right movement of the second ball nut 604 is stable.

[0034] In use, ten platform plates 4 form a printing platform. Tilt sensors 501 in the indicator mechanism 5 on the lower surface of each platform plate 4 monitor whether the platform plate 4 is tilted. When the platform plate 4 tilts, the information is fed back to the controller 502, which triggers the alarm 503 to alert the staff and allow for maintenance. Once the platform plate 4 is level, the 3D printer prints on its upper surface. After printing, the first motor 303 in the first drive mechanism 3, mirrored around the center point of the base plate 1, rotates synchronously. The output shaft of the first motor 303 drives the first ball screw 302 to rotate within the left and right first bearing assemblies 301. The rotation of the first ball screw 302 causes the first ball nut 304 to move to the left. The first ball nut 304, through the second hinge 305 and transmission rod 306, moves the right end of the platform plate 4 downwards. At this time, the left side of the platform plate 4 rotates along the first hinge 202, causing the front and rear mirrored edges to rotate. Platform plate 4 separates from the model. After separation, platform plate 4 returns to its original position. From the outside in, the front and rear mirror platform plates 4 are rotated downwards to separate from the model and then return to their original positions. Therefore, all platform plates 4 will separate from the lower surface of the model. Then, all the first drive mechanisms 3 drive the right ends of all platform plates 4 to move downwards. As a result, the model on the upper surface of platform plate 4 is affected by gravity and moves downwards along the slope of platform plate 4 for unloading. This gives the platform an automatic unloading function, eliminating the need for manual model disassembly and greatly improving unloading efficiency. After unloading, the output shaft of the second motor 603 in the second drive mechanism 6 drives the second ball screw 602 to rotate within the left and right second bearing assemblies 601. The rotation of the second ball screw 602 drives the second ball nut 604 to move left and right. The second ball nut 604 drives the support rod 605 to move left and right, so that the front and rear support rods 605 synchronously drive the scraper 7 to move left and right. The scraper 7 can clean the impurities remaining on the upper surface of platform plate 4, which is beneficial for subsequent printing.

[0035] In summary, the unloading platform of this 3D printer enables the platform to have an automatic unloading function, eliminating the need for manual model disassembly and greatly improving unloading efficiency. It can also monitor the levelness of the platform plate 4 in real time to ensure print quality, and adds an automatic cleaning function to the upper surface of the platform plate 4, which is beneficial for subsequent printing.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
