Detailed ways

In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

The present invention provides an automatically detachable 3D printing device, as shown in FIG. 1 , including a base 100 , a platform assembly 200 and a printing assembly 300 . The platform assembly 200 and the printing assembly 300 are both connected to the base 100, and the base 100 provides support for the platform assembly 200 and the printing assembly 300, has a certain height, and is also convenient for installing the corresponding auxiliary devices of the 3D printing equipment, such as for opening and closing The switch 120 of the 3D printing device, the external interface 130 for file import and export and network connection, etc. The printing assembly 300 is capable of printing objects, including a print head 300, a feeder 310, and the like. The platform assembly 200 can carry all or part of the printed object (not shown in the figure). During the printing process, the object is in direct contact with the platform assembly 200 and can drive the object to move relative to the base 100 together. The platform assembly 200 can drive the object to move together by means of rotation, reciprocating motion, etc. During the moving process, the object remains relatively stationary with the platform assembly 200 under the action of static friction. During the moving process, the relative relationship between the platform assembly 200 and the object and the base 100 The position changes to allow space for subsequent objects or the back of the object to be printed, allowing for continuous printing at the same time during the movement. When the volume of the printed object is small, the object is moved after printing, which is convenient for one object to be printed in line; when the volume of the printed object is large, part of the printed object can be moved. Print. When the platform assembly 200 drives the object to move to the edge of the base 100 , since the base 100 has a certain height, the object leaves the platform assembly 200 under the action of gravity, and can be automatically separated from the 3D printing device, facilitating continuous printing on the platform assembly 200 . The present invention can realize the movement of all or part of the printing object through the platform assembly 200 during printing, realize the automatic separation of the printing object from the 3D printing device, facilitate continuous printing, and improve the printing efficiency.

As an optional embodiment, as shown in FIGS. 1 and 1 , the platform assembly 200 includes a motor 210 , a driving roller 220 , a driven roller 230 and a printing table 240 , and the printing table 240 is in direct contact with the printed object. The motor 210 is threadedly connected with the base, and the motor 210 drives the driving roller 220 to rotate through a belt; the printing table 240 is preferably a flexible material, such as cloth, leather, plastic, etc., so that the printing table 240 wraps the driving roller 220 and the driven roller 230 inside. When the motor 210 drives the driving roller 220 to rotate, the printing table 240 moves relative to the base 100 , and at the same time, driven by the printing table 240 , the driven roller 230 also rotates together. During printing, driven by the motor 210, the printing table 240 can move all the time. At the same time, the moving speed of the printing table 240 driven by the motor 210 should also be relatively low, so as to keep the matching of the moving speed of the printing table 240 and the printing speed, and at the same time, the printing table 240 and the object move relative to the base 100 together, so as to prevent the object from slipping out Printing table 240 . As shown in FIG. 2 , the platform assembly 200 further includes a support rod 250. The support rod 250 is arranged between the driving roller 220 and the driven roller 230, and can support the printing table 240 to avoid the printing table due to the gravity of the object during printing. 240 produces collapse, which affects the printing effect. The support rods 250 are staggered up and down, which can increase the height of the platform assembly 200 and facilitate the motor 210 to drive the printing table 240 to rotate. The number of support rods 250 is preferably three, which can better achieve the support function.

As an optional embodiment, the platform assembly 200 further includes a heating plate (not shown in the figure), and the heating plate is arranged inside the printing table 240 and can be supported by the support rod 250 to heat the printing table 240. The heating plate can Keep the ambient temperature of the printed object basically the same as it, so as to prevent the object from warping due to the effect of external low temperature after printing, which will affect the printing quality of the object.

As an optional embodiment, as shown in FIG. 1-FIG. 2, the driven roller 230 is connected with an adjusting screw 260, the adjusting screw 260 can adjust the position of the driven roller 230, and the adjusting thread 260 adjusts the driven roller by means of screw transmission s position. After the adjusting screw 260 adjusts the position of the driven roller 230, the distance between the driving roller 220 and the driven roller 230 increases or decreases, which can adjust the tension of the printing table 240, and also facilitates the rotation of the printing table 240 relative to the base 100. The position can be fine-tuned to better suit the printing needs.

As an optional embodiment, the material of the printing table 240 is carbon fiber cloth and the surface of the carbon fiber cloth is textured. The carbon fiber cloth is convenient for the motor 210 to drive the printing table to rotate, and the texture on the surface of the carbon fiber cloth is convenient for increasing the distance between the object and the printing table. The friction between the objects prevents the object from sliding out of the printing table 240, and the mesh reduces the contact area between the object and the printing table 240, which facilitates automatic peeling between the object and the printing table and prevents adhesion.

As an optional embodiment, as shown in FIGS. 1 to 2 , the base 100 further includes a connecting piece 110 , and the connecting piece 110 is connected to the base 100 above the base 100 . indivual. Two connecting pieces are distributed on both sides above the base 100 , and the platform assembly 200 is arranged between the two connecting pieces 110 . Both ends of the driving roller 220 and the driven roller 230 are threadedly connected to the connecting member 110 . The support rod 250 is connected with the connecting piece 110 in a snap-fit connection. The connecting piece 110 is provided with protruding stripes, and the two ends of the support rod 250 are provided with matching grooves.

The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention. should be included within the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
