[0002] A 3D printer is a device that stacks hot-melt materials layer by layer to form components. Different from traditional planar printing, the 3D printer is connected to a computer host, and the pre-drawn CAD drawing is sent to the 3D printer, and the hot-melt resin material ejected by the print head is used to construct the finished product.

[0003] However, the printer platforms at the present stage often lack heat dissipation and purification tools. It is inevitable that the hot-melt resin produces peculiar smell during the processing process, which then pollutes the surrounding working environment. It is necessary to manually disperse the smell or wait for the smell to dissipate before the printer can be used again. It is difficult to improve the printing efficiency and is not very safe.

[0004] Now, a new working platform for a 3D printer is proposed to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a working platform for a 3D printer to solve the problem of easy generation of peculiar smell of the 3D printer proposed in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A working platform for a 3D printer, including a table body and a disk body. A disk body is arranged at the center of the top of the table body. Side rods are respectively fixed at the rear of both sides of the top of the table body, and a cross beam is welded between the tops of the side rods. A motor is fixed at the center of the inside of the cross beam. A lead screw is movably connected to the center of the bottom of the cross beam, and a sleeve is sleeved outside the lead screw.

[0009] Preferably, assembly grooves are respectively arranged on both sides of the inside of the disk body, and air cylinders are assembled between the front and rear of the inside of the assembly grooves. A motor is assembled at the center of the front end of the disk body, and a printing table is movably connected to the center of the inside of the disk body. Limit grooves are respectively horizontally arranged on both sides of the inside of the printing table, and clamping rods are movably inserted in the limit grooves.

[0010] Preferably, the center of the bottom of the clamping rod is fixedly connected to the piston rod of the cylinder, and the clamping rod can move left and right along the limiting groove.

[0011] Preferably, the output shaft of the motor is fixedly connected to a plate below the printing table, and the printing table can swing left and right on the top of the disk.

[0015] (1) An annular plate is fixed transversely at the front end of the shaft sleeve, and the motor is started to rotate the screw rod at the rear between the crossbeam and the table body. Since the two sides of the annular plate are respectively embedded in the clamping blocks, the shaft sleeve and the annular plate can be vertically lifted or lowered when the screw rod is rotated, so that the annular plate is sleeved on the outside of the object on the surface of the printing table, and then the negative pressure fans on both sides are started to circulate the air flow into the cavity, and the air flow is adsorbed and purified by the bamboo charcoal particles in the air permeable box to prevent the polluted gas from spreading to the surrounding environment;

A motor 6 is fixed at the center of the inside of the cross beam 5. A lead screw 7 is movably connected to the center of the bottom of the cross beam 5, and a bush 9 is sleeved outside the lead screw 7. An annular plate 8 is horizontally fixed at the front end of the bush 9. Air fans 10 are respectively assembled on the outer parts of both sides of the annular plate 8. Cavities 17 are respectively provided on both sides of the inner wall of the annular plate 8, and ventilation boxes 18 are inserted and fixed in the cavities 17. Bamboo charcoal particles 19 are filled in the ventilation boxes 18. Blocks 4 are respectively welded on both sides of the top of the annular plate 8;

[0025] The side surface of the block 4 is embedded in the sliding groove 3, and the block 4 and the annular plate 8 are lifted and lowered synchronously. The lead screw 7 is embedded in the bush 9, and the motor 6 can control the lead screw 7 to rotate in place;

[0026] Specifically, as shown in Figure 1 and Figure 2As shown, start the motor 6 to rotate the lead screw 7 at the rear between the cross beam 5 and the table body 1. Since both sides of the annular plate 8 are respectively embedded in the clamping blocks 4, when the lead screw 7 rotates, the shaft sleeve 9 and the annular plate 8 can be vertically lifted or lowered, so that the annular plate 8 is sleeved outside the object on the surface of the printing table 11. Then start the negative pressure fans 10 on both sides to circulate and extract the air flow into the cavity 17, and accept the adsorption and purification treatment of the bamboo charcoal particles 19 in the air permeable box 18.

[0027] Embodiment 2: Assembly grooves 21 are respectively arranged on both sides inside the disc body 12, and air cylinders 22 are assembled between the front and rear of the inside of the assembly grooves 21. A motor 23 is assembled at the center of the front end of the disc body 12, and a printing table 11 is movably connected to the center of the inside of the disc body 12. Limiting grooves 20 are respectively horizontally arranged inside both sides of the printing table 11, and clamping rods 24 are movably inserted into the limiting grooves 20;

[0028] The center of the bottom of the clamping rod 24 is fixedly connected to the piston rod of the air cylinder 22. The clamping rod 24 can move left and right along the limiting groove 20. The output shaft of the motor 23 is fixedly connected to the plate below the printing table 11. The printing table 11 can swing left and right on the top of the disc body 12;

[0029] Specifically, as Figure 1 and Figure 3 shown, the rod body at the bottom end of the printing table 11 is hinged inside the disc body 12 and can be controlled by the motor 23 assembled on the surface to swing left and right. During this process, the air cylinders 22 in the two assembly grooves 21 on both sides will also lift or lower the clamping rod 24 with the telescopic piston rod, so that the clamping rod 24 slides left and right along the limiting groove 20 to maintain the stability when the top printing table 11 is tilted.

[0030] Embodiment 3: A groove 13 is arranged at the center of the front end of the table body 1, and a slide plate 16 is movably connected in the groove 13. Ball bearings 14 are respectively embedded at the four corners of the bottom of the slide plate 16. The top of the slide plate 16 is fixedly connected to the disc body 12. A heating box 15 is welded at the center of the rear of the bottom of the table body 1, and a control board 27 is assembled behind the heating box 15. A frame body 25 is welded at the rear of the top of the table body 1, and a baffle 26 is movably inserted between the front and rear of the lower part inside the frame body 25. The frame body 25 is communicated with the heating box 15. A discharge pump 28 is assembled at the bottom front end of the heating box 15;

[0031] Specifically, as Figure 1 and Figure 4 shown, after the printing is completed, pull out the baffle 26 in the frame body 25, sweep the debris and scraps contaminated on the surface mechanism of the table body 1 into the frame body 25 and then fall into the heating box 15 at the bottom to melt, so as to be extracted from the discharge pump 28 and reused. Take out the slide plate 16 and the disc body 12 along the groove 13 and under the lubrication of the ball bearings 14, and then the finished product can be peeled off from the printing table 11.

[0032] Working principle: When the utility model is in use, the rod body at the bottom of the printing table 11 is hinged inside the disc body 12 and can swing left and right under the control of the surface-mounted motor 23. During this process, the cylinders 22 in the assembly grooves 21 on both sides will also push up or lower the clamping rod 24 with the telescopic piston rod, so that the clamping rod 24 slides left and right along the limiting groove 20 to maintain the stability when the top printing table 11 is tilted, and receive the items made by the 3D printer from different angles. After that, start the motor 6, and rotate the lead screw 7 behind the cross beam 5 and the table body 1. Since both sides of the annular plate 8 are respectively embedded in the clamping blocks 4, when the lead screw 7 is rotated, the sleeve 9 and the annular plate 8 can be vertically lifted or lowered, so that the annular plate 8 is sleeved outside the object on the surface of the printing table 11. Then start the negative pressure fans 10 on both sides to circulate and extract the air flow into the cavity 17, and receive the adsorption and purification treatment of the bamboo charcoal particles 19 in the breathable box 18. Finally, pull out the baffle 26 in the frame body 25, sweep the debris and scraps contaminated on the mechanism on the surface of the table body 1 into the frame body 25 and then fall into the heating box 15 at the bottom to melt, so as to be extracted from the discharge pump 28 and reused, and take out the slide plate 16, the disc body 12 and the finished product along the groove 13 and under the lubrication of the ball 14.
