Description
Предполагаемая полезная модель относится к оборудованию для изготовления 3D-прототипов деталей из различных полимерных материалов по FDM (Fused Deposition Modeling) технологии. Устройство может быть использовано в любых конструкциях 3D-принтеров, работающих по FDM-технологии с одним, двумя или более экструдерами.The proposed utility model relates to equipment for the manufacture of 3D prototypes of parts from various polymeric materials according to FDM (Fused Deposition Modeling) technology. The device can be used in any design of 3D-printers, working on FDM-technology with one, two or more extruders.
В технике уже известны аналогичные технические решения, сущность которых заключается в том, что печатающая головка (экструдер) 3D-принтера выдавливает на платформу (стол) разогретый полимерный материала. Известен 3D-принтер со сменными печатающими соплами - WO 2015038072, (BIO3D TECHNOLOGIES PTE LTD, SG), B33Y 10/00, от 19.03.2015 г.Similar technical solutions are already known in the art, the essence of which lies in the fact that the print head (extruder) of a 3D printer squeezes heated polymer material onto a platform (table). Known 3D printer with interchangeable print nozzles - WO 2015038072, (BIO3D TECHNOLOGIES PTE LTD, SG), B33Y 10/00, dated 03/19/2015.
Наиболее близкие аналогичные решения раскрыты в следующей патентной документации: CN 203945698, (CHEN LIANG), 19.11.2014 г., - «Раздаточная головка 3D принтера», CN 104149352, (SANYA SIHAI INNOVATIVE ELECTRICAL AND MECHANICAL ENGINEERING CO., LTD, CHEN MINGOJAO), 19.11.2014 г. - «Раздаточная головка 3D-принтера».The closest similar solutions are disclosed in the following patent documentation: CN 203945698, (CHEN LIANG), 11/19/2014, - “Distribution head of a 3D printer”, CN 104149352, (SANYA SIHAI INNOVATIVE ELECTRICAL AND MECHANICAL ENGINEERING CO., LTD, CHEN MINGOJAO ), 11/19/2014 - “Distribution head of a 3D printer."
Недостатком представленных изобретений является невозможность быстрой и плавной регулировки зазора между соплом экструдера и областью печати (нагревательный стол), по причине жестко связанной конструкции экструдера на резьбовых элементах.The disadvantage of the presented inventions is the inability to quickly and smoothly adjust the gap between the extruder nozzle and the print area (heating table), due to the rigidly connected extruder design on the threaded elements.
Прототипом устройства плавной регулировки сопла экструдера 3D-принтера является печатающая головка струйного 3D-принтера. Экструдер, который включает основание, на котором закреплен механизм подачи печатающего материала, двигатель, выполненный с возможностью вращения эксцентрика, который приводит в движение единую платформу, клапаны, выполненные с возможностью запирания неактивного экструдера, единую платформу, которая содержит два легкосъемных экструдера с нагревательными элементами, самозапирающийся механизм переключения, выполненный с возможностью позиционирования сопел в рабочем положении, и подпружиненные ролики (патент №171905, МПК B41J 2/00, д.п. 20.06.2017 г.).The prototype of the device for smooth adjustment of the nozzle of the extruder of a 3D printer is the print head of an inkjet 3D printer. An extruder, which includes a base on which the feeding mechanism of the printing material is fixed, an engine configured to rotate the eccentric, which drives a single platform, valves configured to lock the inactive extruder, a single platform that contains two easily removable extruders with heating elements, self-locking switching mechanism made with the possibility of positioning the nozzles in the working position, and spring-loaded rollers (patent No. 171905, IPC B41J 2/00, dp 20.06.2017 g.).
К недостаткам прототипа следует отнести технологическую сложность изготовления конструкции с высокой точностью. Поворотные сопла могут находиться на разном уровне от стола при печати, что вызывает низкое качество печати. Регулировка равномерного зазора сразу между двумя соплами и столом за счет резьбы сопел очень трудоемкая операция. Шаг резьбы сменных сопел порой не позволяет достигать одинаковости зазора между соплом и столом точнее 0,1 мм при смене работы сопла.The disadvantages of the prototype include the technological complexity of manufacturing structures with high accuracy. Swivel nozzles may be at different levels from the table when printing, which causes poor print quality. Adjusting the uniform gap immediately between two nozzles and the table due to the thread of the nozzles is a very time-consuming operation. The thread pitch of interchangeable nozzles sometimes does not allow to achieve the same gap between the nozzle and the table more precisely 0.1 mm when changing the nozzle operation.
Преимущество заявляемого устройства заключается в том, что в радиаторе охлаждения экструдера отсутствует крепежная резьба, а термобарьер закрепляется в радиаторе по гладкой цилиндрической скользящей посадке с фиксацией от осевого перемещения стопорным винтом. Такая конструкция позволяет быстро и плавно выставить необходимый зазор между соплом экструдера и столом с помощью калибра. Особую значимость такая конструкция приобретает при печати с двумя экструдерами, где одинаковый зазор между двумя соплами и столом строго обязателен. При этом калибровка зазоров может осуществляться листом бумаги необходимой толщины. Погрешность такой калибровки не превышает 0,05 мм.An advantage of the inventive device is that there is no fastening thread in the extruder cooling radiator, and the thermal barrier is fixed in the radiator by a smooth cylindrical sliding fit with fixation from axial movement by a locking screw. This design allows you to quickly and smoothly set the required clearance between the extruder nozzle and the table using caliber. This design becomes especially significant when printing with two extruders, where the same gap between the two nozzles and the table is strictly required. In this case, the calibration of the gaps can be carried out with a sheet of paper of the required thickness. The error of such a calibration does not exceed 0.05 mm.
Техническим результатом предполагаемой полезной модели является уменьшение времени на настройку оборудования перед началом эксплуатации, увеличение точности калибровки зазоров между соплами экструдеров и столом принтера, что позволит повысить качество печати и исключить дефекты, связанные с разницей зазоров между столом и соплами экструдера.The technical result of the proposed utility model is to reduce the time to set up the equipment before operation, increase the accuracy of calibration of the gaps between the extruder nozzles and the printer table, which will improve print quality and eliminate defects associated with the difference in the gaps between the table and the extruder nozzles.
Технический результат достигается тем, что устройстве плавной регулировки сопла экструдера 3D-принтера, работающего по FDM-технологии, включающем радиатор охлаждения, термобарьер, нагревательный блок, сопло, при этом радиатор охлаждения и термобарьер содержат скользящую посадку по цилиндрической поверхности с фиксацией стопорным винтом.The technical result is achieved in that the device for smooth adjustment of the nozzle of the extruder of a 3D printer using FDM technology, including a cooling radiator, a thermal barrier, a heating block, a nozzle, while the cooling radiator and thermal barrier contain a sliding fit on a cylindrical surface with fixation by a locking screw.

Устройство плавной регулировки сопла экструдера 3D-принтера, работающего по FDM-технологии, включает в себя: термобарьер 1, радиатор охлаждения 2, стопорный винт 3, нагревательный блок 4, сопло 5.The device for smooth adjustment of the nozzle of the extruder of a 3D printer using FDM technology includes: a
Принцип работы устройства: для создания необходимого зазора между столом принтера и соплом экструдера выкручиваем стопорный винт 3, при этом термобарьер 1 станет подвижным относительно радиатора охлаждения 2. Далее между столом принтера и соплом экструдера вставляется калибровочная пластина, толщина которой равна требуемому зазору, после касания конца сопла пластины термобарьер 1 фиксируется винтом 3 от перемещений относительно радиатора охлаждения 2. При схеме печати с двумя экструдерами и более принцип калибровки на равный зазор аналогичен.The principle of the device: to create the necessary clearance between the printer table and the extruder nozzle, unscrew the
