Example

[0025] See also Figure 1-5 , the technical solution provided by this embodiment is as follows:

[0026] A printing platform of a large-scale 3D printer comprises a base 1, a supporting mechanism 2 is arranged on the top of the base 1, the supporting mechanism 2 comprises a supporting pole 201, a supporting plate 202 and an electric telescopic rod 203, the supporting pole 201 is fixedly connected to the top of the base 1, the supporting plate 202 is movably connected to the surface of the supporting pole 201, the electric telescopic rod 203 is respectively fixedly connected to the four corners of the top of the base 1, a cleaning mechanism 3 is arranged on the top of the supporting plate 202, the cleaning mechanism 3 comprises a brushing soft board 301, an oil storage pipe 302, a cleaning scraper 303 and a sealing plug 304, the brushing soft board 301 is movably connected to the top of the supporting plate 202, the oil storage pipe 302 is fixedly installed on the top of the brushing soft board 301, the cleaning scraper 303 is installed at the bottom end of the left side of the oil storage pipe 302, and the sealing plug 304 is fixedly connected to the top of the brushing soft board 301.

[0027] refer to Figure 1-4There are multiple groups of support poles 201, which are distributed in an equidistant array and fixedly connected to the top of the base 1. The top of the electric telescopic rod 203 is fixed to the four corners of the bottom of the support tray 202. The bottom of the soft painting board 301 is in contact with the top of the support tray 202, and the bottom end of the cleaning scraper 303 is in contact with the top of the support tray 202. The sealing plug 304 is arranged in the inner cavity of the oil storage pipe 302, and the input end of the oil storage pipe 302 is fixedly installed with an oil delivery spring hose 4. The front and rear sides of the support tray 202 are fixedly connected with support tooth plates 5, and the four sides of the base 1 are provided with mounting screw holes 10.

[0028] The above scheme is adopted: by controlling the electric telescopic rod 203 to drive the support plate 202 to move up and down, so that the upper surface of the support upright 201 is aligned with the upper surface of the support plate 202 and the staggered action is performed, which is convenient for demoulding the finished product and improves the working efficiency of the device. By applying the brushing soft board 301 to the support plate 202, the oil layer can be even when the support plate 202 is brushed with oil, and there will be no uneven thickness. By setting the sealing plug 304, the brushing soft board 301 can be moved on the surface of the support plate 202. During the process, the soft brushing plate 301 is offset due to friction, thereby driving the sealing plug 304 to move slightly, so that a small amount of oil leaks from the output port of the oil storage pipe 302 to the soft brushing plate 301, thereby providing oil for the continuous coating of the soft brushing plate 301. By setting the oil supply spring hose 4, the oil supply pipe 302 can be continuously supplied with oil, and the retractable elastic properties of the oil supply spring hose 4 prevent it from affecting the normal operation of the device. By setting the mounting screw holes 10, the device can be fixed to the specified installation position with bolts.

[0029] refer to Figure 1 , Figure 2 and Figure 5 The surface of the supporting tooth plate 5 is movably connected with a movable transverse block 6, the inner cavity of the movable transverse block 6 is movably connected with a driving shaft 8, the surface of the driving shaft 8 is fixedly connected with a driving gear 9, the surface of the driving gear 9 is meshingly connected with the inner side of the supporting tooth plate 5, the bottom end of the movable transverse block 6 is fixedly installed with a driving motor 7, the output end of the driving motor 7 is fixedly connected to the bottom end of the driving shaft 8, the inner side of the top of the movable transverse block 6 is respectively fixedly connected to the front and rear ends of the oil storage pipe 302, the surface of the top of the driving shaft 8 is fixedly sleeved with a bearing body 11, and the surface of the bearing body 11 is fixedly sleeved in the inner cavity of the movable transverse block 6.

[0030] The above scheme is adopted: through the setting of the movable transverse block 6, the oil storage pipe 302 can be supported and fixed, and the setting of the drive shaft 8 and the drive gear 9 can make the movable transverse block 6 move at a uniform speed. Through the setting of the drive motor 7, the driving force can be provided for the movement of the movable transverse block 6. Through the setting of the bearing body 11, the surface wear on the top of the drive shaft 8 can be reduced, thereby increasing its service life.

[0031] Working principle: The device is installed to the designated installation position of the printer by using bolts to pass through the installation screw holes 10, the oil delivery spring hose 4 is installed and connected to the oil storage pipe 302 and the isolation oil is delivered to the inner cavity of the oil storage pipe 302, and the device is electrically connected to the printer by using the control harness to provide power and control signals to control the device, and the electric telescopic rod 203 is controlled to drive the support plate 202 to move up and down, so that the top of the support pole 201 is flush with the top of the support plate 202 to form a plane, and then the drive motor 7 is controlled to work to drive The driving shaft 8 rotates, and the driving gear 9 is driven to rotate by the rotation of the driving shaft 8. The driving gear 9 is rotated and meshed with the inner side of the supporting tooth plate 5, so that the driving gear 9 rolls on the inner side of the supporting tooth plate 5 to drive the movable transverse block 6 to move. The movement of the movable transverse block 6 drives the oil storage pipe 302 to move. The movement of the oil storage pipe 302 drives the cleaning scraper 303 and the brushing soft board 301 to move to the left side of the supporting support plate 202. The bottom of the brushing soft board 301 and the cleaning scraper 303 is attached to the top of the supporting support plate 202, so that the cleaning scraper 303 is moved to the left side of the supporting support plate 202. During the movement, the floating dust and other residues on the top of the support pole 201 and the support plate 202 are scraped off, so that the soft brushing board 301 is displaced due to friction during the movement, and the displacement of the soft brushing board 301 drives the sealing plug 304 to shake, so that a gap appears at the output port of the oil storage tube 302, and the isolation oil in the inner cavity of the oil storage tube 302 leaks to the soft brushing board 301 through the gap, and the isolation oil is dispersed by the soft brushing board 301 and evenly applied to the top of the support plate 202 and the support pole 201, so as to reduce the adhesion between the printing material and the support pole 201 and the top of the support plate 202. The paint brush 301 and the cleaning scraper 303 are reset, and the printing device is controlled to print on the top of the support pole 201 and the support plate 202. After printing, the electric telescopic rod 203 is controlled to drive the support plate 202 to move downward, and the finished product is supported by the support pole 201 to separate the bottom of the finished product from the top of the support plate 202. After separation, the support plate 202 is controlled to move upward to support the finished product, so that the top of the support pole 201 is separated from the bottom of the finished product, thereby completing the demoulding and separation of the finished product.
