Description

Technical Field

[0001] The present invention relates to the technical fields of 3D printing, additive manufacturing, and additive manufacturing equipment manufacturing, and specifically relates to an adjustable automated 3D printing device. Background Art

[0002] 3D printing, also known as additive manufacturing, is a technology for manufacturing three-dimensional objects by layer-by-layer stacking of materials. It subverts the "subtractive" or "forming" processes of traditional manufacturing, and has the characteristics of being fast, flexible, and highly customizable. The advantages of 3D printing include design freedom, rapid prototyping, customized production, etc. Currently, 3D printers are generally used for printing production. A 3D printer consists of components such as an extrusion system, a cooling system, a motion system, and a heated bed.

[0003] The patent with the application number 201620598245.3 mentions "a 3D printing device". This patent is made of a full-frame structure, and the working process is clear at a glance. The nozzle is made of brass material, which is beneficial to improving work efficiency and is not easily damaged during the working process. There are light-emitting bodies arranged around the movement mechanism to improve work efficiency.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. A multi-adjustment switching component is provided. The load-bearing reciprocating frame is driven to move by the reciprocating electric slide rail and the alignment electric slide rail, and the switching motor drives the switching integration disc and the wire-passing electric heating block to rotate, directly performing switching processing on the extrusion processing head. The cutting hydraulic cylinder drives the cutting knife to cut the wire, and the wire is guided by the concave wire-passing pipe and the wire-passing fixing groove. The wire inlet motor and the wire inlet gear push the wire to move in and out, so that when replacing the extrusion processing head, the wire inlet processing can be quickly carried out without manual operation by the staff, and there is no need to stop the machine for processing, improving the processing speed. The wire is continuously heated by the wire-passing electric heating block and the external thread electric heating head. The air pump and the inlet and outlet pipe frame are used to perform air inlet and exhaust processing on the double-hole input cavity. The pressing electric slide rail drives the pressing processing plate to extrude the hot melt material, controlling the discharge extrusion speed, realizing continuous and stable discharge, and slag cleaning can be carried out inside when replacing the extrusion processing head, facilitating subsequent production processing. When dealing with products of different sizes and different printing requirements, there is no need to stop the machine for wire in and out processing, and multiple printing heads of the equipment cooperate with each other and directly switch, reducing the waiting time for printing head replacement, improving the processing speed, and ensuring the printing replacement and continuous printing speed.

[0017] 2. The lifting integration block is driven to lift by the servo motor and the lifting lead screw, the positioning processing frame is driven to rotate by the flipping motor, and the correction processing frame is driven to rotate by the correction motor, so that the bearing platform and the lifting lead screw are gradually switched from a vertical state to a horizontal state, realizing multi-angle correction processing. The hydraulic inlet and outlet power box and the liquid injection pipe control the oil level in the liquid injection sealing box, adjusting the height of the lifting piston and the correction universal joint. The horizontal degree of the bearing platform placement is adjusted through multiple groups of universal joints, and with large-angle rotation, arbitrary angle adjustment of the bearing platform is realized. Combined with positioning lifting movement and horizontal and vertical movement of the top printing position, three-axis positioning printing is formed. When dealing with complex printing or printing with suspended components in the middle, the printing can be directly carried out through angle adjustment, reducing the need for support printing during the printing process, thereby reducing the printing production volume and printing consumables volume, improving the printing efficiency, and increasing the printing processing range.

[0018] 3. By driving the extrusion processing head to move horizontally and vertically and the platform to move vertically, three-axis printing processing is achieved. By using rotation switching and reciprocating movement of the gear to push the material, continuous feeding and print head replacement processing are realized. In cooperation with the multi-angle replacement of the bearing platform, the range of printing processing is improved, effectively solving the problem in the prior art that during the printing process, the size of the extrusion head cannot be directly and quickly adjusted and the platform is fixed during printing. When complex printing and overhanging printing occur, a large number of brackets need to be printed. This enables the direct change of the extrusion head size and the extrusion material size during printing, quickly responding to printing processing of different sizes and different requirements. In cooperation with the angle change, the operation range and complexity of printing are increased, the printing production efficiency is improved, and the product quality is guaranteed.

[0019] 4. An inlet, fixing, cooling and matching component is provided. The clamping position limiting frame is embedded in the side end of the wire coil. The fixing limit frame and the winding limit sleeve are used to limit and clamp the clamping position limiting frame. The wire is passed through the threading positioning wheel and the clamping threading box, and the spring return rod drives the wire clamping processing block to push the wire to move and clamp it. The winding motor drives the winding limit sleeve and the clamping position limiting frame to rotate, pushing the wire coil to rotate, performing the winding and unwinding processing of the wire, pulling the wire in and out for processing, controlling the feeding speed and the feeding tightness of the wire, ensuring the stability of the incoming wire. The condensing heat exchanger cools the coolant in the cooling processing box. The circulating pump and the circulating alternating pipe drive the coolant in the cooling processing box to flow. The coolant cools and flows along the circulating alternating pipe and the circulating cooling cavity, and the coolant is used to absorb heat and cool the bearing platform and the printed and formed product, realizing continuous cooling operation, and ensuring the cooling forming speed of the product and the quality of product shaping.

[0020] In summary, through the mutual cooperation of the multi-adjustment switching component and the inlet, fixing, cooling and matching component, through the mutual cooperation of gear extrusion, rotation and reciprocating feeding, external limit clamping and pushing feeding, the speed of continuous feeding is guaranteed, and the situation of feeding interruption caused by waiting for feeding is reduced. By using air cooling to cool the printing position and water cooling to cool the platform, the rapid cooling setting and continuous cooling setting are mutually coordinated, improving the product forming efficiency and the product setting quality, realizing the steady printing production of the product. At the same time, by increasing the cooling speed, the printing speed can be effectively increased. BRIEF DESCRIPTION OF THE DRAWINGS
