Description

Technical Field

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

[0002] 3D printing, also known as additive manufacturing, is a technology that creates three-dimensional objects by stacking materials layer by layer. It subverts the "subtractive" or "molding" process of traditional manufacturing and is fast, flexible and highly customized. The advantages of 3D printing include design freedom, rapid prototyping, customized production, etc. 3D printers are generally used for printing and production. 3D printers are composed of extrusion systems, cooling systems, motion systems, hot beds and other components.

[0003] The patent application number 201620598245.3 mentions "a 3D printing device". The patent is made of a full frame, and the working process is clear at a glance.

[0043] Compared with the prior art, the beneficial effects of the present invention are:

[0044] 1. There are multiple adjustment and switching components. The reciprocating electric slide rail and the alignment electric slide rail are used to drive the load-bearing reciprocating frame to move. The switching motor drives the switching integration disk and the threading electric heating block to rotate, directly performing switching processing on the extrusion processing head. The cutting hydraulic cylinder is used to drive the cutting knife to cut the wire. The concave threading pipe and the threading fixing groove are used to guide the wire. The wire inlet motor and the wire inlet gear push the wire to move in and out, enabling fast wire inlet processing when replacing the extrusion processing head, without the need for manual operation by staff and without the need for shutdown processing, improving the processing speed. The wire is continuously heated by the threading electric heating block and the external thread electric heating head. The air pump and the inlet and outlet pipe frames 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 enabling slag cleaning 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 for shutdown wire in and out processing, and multiple printing heads of the equipment cooperate with each other and directly switch, reducing the waiting time for replacing the printing head and improving the processing speed, ensuring the printing replacement and continuous printing speed.

[0045] 2. The servo motor and the lifting screw drive the lifting integration block to rise and fall, the flip motor drives the positioning processing frame to rotate, and the correction motor drives the correction processing frame to rotate, so that the bearing platform and the lifting screw are gradually switched from a vertical state to a horizontal state to achieve multi-angle correction processing. The hydraulic inlet and outlet power box and the injection pipe control the oil height in the injection sealing box, adjust the height of the lifting piston and the correction universal joint, and adjust the horizontality of the bearing platform through multiple sets of universal joints. With the large-angle rotation, the bearing platform can be adjusted at any angle. With the positioning lifting movement and the horizontal and vertical movement of the top printing position, three-axis positioning printing is formed. When printing complex prints or when there are suspended parts in the middle, the printing process can be directly adjusted by angle adjustment, reducing the need for bracket printing during the printing process, thereby reducing printing production and printing consumables, thereby improving printing efficiency and increasing the printing processing range.

[0046] 3. The three-axis printing process is realized by driving the extrusion processing head of the printing horizontally and vertically and the vertical movement of the platform. The rotation switching and the reciprocating movement of the gear pusher are used to realize continuous feeding and print head replacement processing. The multi-angle replacement of the carrying platform is coordinated to improve the range of printing processing. It effectively solves the problem in the existing technology that the size of the extruder head cannot be directly and quickly adjusted during the printing process and the platform is fixed during printing, resulting in the need to print a large number of brackets for complex printing and suspended printing. The extruder head size and the extrusion material size can be directly changed during printing, and the printing process of different sizes and different requirements can be quickly responded to. With the change of angle, the operating range and complexity of printing are increased, the efficiency of printing production is improved, and the quality of the product is guaranteed.

[0047] 4. A feed cooling assembly is provided, and the positioning limit frame is embedded in the side end of the wire drum, and the positioning limit frame is limited and connected by the fixed limit frame and the winding limit sleeve. The wire is passed through the threading positioning wheel and the clamping threading box, and the spring reset rod is used to drive the wire clamping processing block to push the wire to move and clamp. The winding motor drives the winding limit sleeve and the positioning limit frame to rotate, pushes the wire drum to rotate, and the wire is retracted and released, and the wire is pulled in and out for processing. The wire feeding speed and feeding tightness are controlled to ensure the stability of the incoming wire. The coolant in the cooling treatment box is cooled by the condensing heat exchanger, and the circulating pump and the circulating alternating pipe drive the coolant in the cooling treatment box to flow. The coolant flows along the circulating alternating pipe and the circulating cooling cavity for cooling, and the coolant is used to absorb heat and cool the carrying platform and the printed products to achieve continuous cooling operation, ensuring the speed of product cooling and molding and the quality of product shaping.

[0048] In summary, through the cooperation of the multi-adjustment switching component and the feed setting and cooling component, the gear extrusion rotation reciprocating feeding cooperates with the outer limit clamping and push feeding to ensure the speed of continuous feeding, reduce the occurrence of feeding interruption caused by feeding waiting, use air cooling to cool the printing position and water cooling to cool the platform, realize the cooperation of rapid cooling and shaping and continuous cooling and shaping, improve product molding efficiency and product shaping quality, realize steady product printing production, and at the same time, by increasing the cooling speed, the printing speed can be effectively improved.

[0096] For the stable operation of the equipment, the input ends of the condensation heat exchanger 304, the circulation pump 305, the leveling electric push rod 308 and the winding motor 311 are all electrically connected to the output end of an external controller.

[0097] The working principle and usage process of the present invention: Before 3D printing, the staff places the outer frame limiting frame 1 at the production position, pulls out the transparent protective sleeve 302 from the inner concave limiting strip 301, and removes the transparent protective sleeve 302 along the outer frame limiting frame 1, and expands the outer frame limiting frame 1. The leveling electric push rod 308 drives the outer frame limiting frame 1 to move up and down at each position to adjust the overall flatness of the outer frame limiting frame 1, and uses the anti-slip treatment pad 309 to perform anti-slip treatment on the equipment to achieve the equipment placement treatment;

[0098] After the placement is completed, the positioning limit frame 313 is embedded into the side end of the wire drum, and the positioning limit frame 313 is inserted into the winding limit sleeve 312 position at the side end of the fixed limit frame 310 to realize the fixed limit of the wire drum, and the wire is passed into the side end of the threading positioning wheel 315 at the position of the limit operating frame 314, and passed through the clamping threading box 316, and the wire is passed into the inner side of the threading fixed groove 219 at the position of the load-bearing reciprocating frame 218. The wire feeding motor 220 drives the wire feeding gear 221 to rotate, and the wire feeding gear 221 is used to push the wire along the threading fixed groove 219 moves to realize wire threading processing. When the wire is fed in, the winding motor 311 drives the winding limit sleeve 312 and the clamping limit frame 313 to rotate along the fixed limit frame 310, pushing the wire drum to rotate and loosening the wire. When the wire is in the clamping and threading box 316, the spring return rod 317 drives the clamping processing block 318 to move along the clamping and threading box 316, and the clamping processing block 318 pushes the wire, thereby adjusting the tightness of the wire, ensuring its steady feeding, avoiding feeding breakage, and realizing steady wire feeding linkage;

[0099] The servo motor 201 drives the lifting screw 202 to rotate along the outer frame limit frame 1, and the lifting screw 202 drives the lifting integration block 203 to move up and down along the outer frame limit frame 1, driving the carrying platform 212 to move up and down to realize the printing lifting process. The flip motor 204 drives the positioning processing frame 205 to rotate and adjust along the lifting integration block 203 to change the angle of the positioning processing frame 205. The correction motor 206 drives the correction processing frame 207 to rotate along the positioning processing frame 205 to change the angle and position of the correction processing frame 207. At this time, the hydraulic inlet and outlet power box 208 and the injection pipe 213 inject hydraulic oil into the injection sealing box 209, and the hydraulic oil pushes the lifting piston 210 along the injection sealing box 2 09 lifting, the lifting piston 210 pushes the correction universal joint 211 to move up and down along the liquid injection sealing box 209, and uses four sets of correction universal joints 211 to change the angle of the carrying platform 212. The horizontal angle detector 214 is used to detect and adjust the angle of the carrying platform 212, and change the carrying printing position and the carrying printing angle. When printing, the angle of the carrying platform 212 can be changed, so that the position when in use can be placed parallel to the screw rod and tilted at multiple angles. The carrying angle can be adjusted according to the printing requirements, which is suitable for printing more complex shapes. At the same time, the part that needs to be printed in the air can be printed directly without the need for a printing bracket, thereby reducing printing consumables and reducing the time required for printing;

[0100] After the wire feeding and fixing are completed, the switching motor 222 drives the switching integration disk 223 to rotate along the load-bearing reciprocating frame 218, adjusts the extrusion processing head 227 of different extrusion sizes according to production needs, rotates the threading electric heating block 224 to the printing position, and aligns the side end of the concave threading tube 232 with the threading fixing groove 219 at the position of the load-bearing reciprocating frame 218. At this time, the wire is driven by the wire feeding gear 221 to move into the inner side of the concave threading tube 232 and inserted into the double-hole input cavity 22. 5 inside, the air inlet and outlet positions of the inlet and outlet pipe rack 231 are controlled by the limiting valve 235. The air pump 230 and the inlet and outlet pipe rack 231 extract the air in the double-hole input chamber 225 and exhaust the inside. At this time, the continuously fed wire is subjected to electric heating treatment by the threading electric heating block 224. The flowing wire after heat melting flows along the double-hole input chamber 225 into the position of the external thread electric heating head 226 and the extrusion processing head 227, and is extruded through the extrusion processing head 227 to realize extrusion printing processing;

[0101] The reciprocating electric slide 215 drives the positioning limit bar 216 to move along the outer frame limit frame 1, and the positioning electric slide 217 drives the load-bearing reciprocating frame 218 to move along the positioning limit bar 216. The reciprocating electric slide 215 and the positioning electric slide 217 cooperate with each other to realize multi-position printing processing. The pressing electric slide 228 drives the pressing processing plate 229 to move along the double-hole input cavity 225, pushing the printing material to be discharged along the double-hole input cavity 225, so that the feeding speed can be controlled during the printing process to ensure the printing speed. The stability of the printing is improved to avoid interruptions in printing, and the fluidity of the material is ensured by continuous heating treatment at multiple positions. When the material is extruded, the reciprocating switching frame 237 is driven by the reciprocating motor 236 to rotate along the load-bearing reciprocating frame 218, changing the angle of the cooling fan 238. The extrusion position is cooled by the cooling fan 238. The simultaneous collision of air from multiple directions forms turbulent cooling, ensuring the cooling effect and avoiding the deformation and offset of the extrusion position caused by direct airflow.

[0102] At the same time, the coolant in the cooling treatment box 303 is cooled by the condensing heat exchanger 304. The circulating pump 305 and the circulating alternating pipe 307 extract the coolant in the cooling treatment box 303. The coolant flows along the circulating alternating pipe 307 into the inner side of the circulating cooling chamber 306 in the carrying platform 212. The coolant absorbs heat and cools the carrying platform 212 and the printed product. After absorbing heat, the coolant flows back to the inner side of the cooling treatment box 303 along the circulating alternating pipe 307, realizing continuous cooling operation and ensuring the speed of product cooling and molding and the quality of product finalization.

[0103] When it is necessary to replace the extrusion processing head 227 with a different extrusion size, the cutting hydraulic cylinder 233 drives the cutting knife 234 to move downward along the load-bearing reciprocating frame 218 and the concave threading tube 232, and the cutting knife 234 is used to cut the wire. At this time, the wire feed motor 220 reverses to drive the wire feed gear 221 to reverse and push the wire to move in the opposite direction, and then pull it out from the concave threading tube 232. The switching motor 222 drives the switching integration disk 223 and the threading electric heating block 224 to rotate, and the extrusion processing head 227 is replaced. At this time, the wire feed motor 220 drives the wire feed gear 221 to push the wire along the threading fixing groove 219 into the inner side of the concave threading tube 232 to realize the hot melt printing process of feeding again.
