A quick-release 3D printer nozzle structure

Abstract

This utility model discloses a quick-release 3D printer nozzle structure, mainly including an X-axis mounting plate, a heat sink, a throat, a heating block, a nozzle, and a quick-release structure. The quick-release structure is linked to a conical push head via multiple sets of elastic moving parts (including limiting posts, springs, limiting discs, and sliding frames) within the structural box. A knob drives a screw to move the conical push head linearly, pushing the limiting posts through or retracting from the through holes, thus locking or releasing them with the limiting holes on the X-axis mounting plate. This structure allows for quick installation and removal of the nozzle by rotating a knob, making operation simple.

Description

Technical Field

[0001] This utility model relates to the technical field of 3D printer nozzle structure, specifically a quick-release 3D printer nozzle structure. Background Technology

[0002] The printhead is one of the core components of a 3D printer. In the current technology, the printhead is fixed to the X-axis mounting plate by bolts or screws. The X-axis motion mechanism drives the X-axis mounting plate and the printhead to move together to achieve the printing work. However, the printhead needs to be disassembled frequently for maintenance, cleaning or replacement. The above connection method requires special tools to disassemble, which is cumbersome and time-consuming, especially in a small installation space, where disassembly and reinstallation are extremely inconvenient. Utility Model Content

[0003] In view of the above-mentioned shortcomings in the existing technology, the purpose of this utility model is to provide a nozzle structure that is simple and convenient to disassemble.

[0004] The technical solution adopted by this utility model to achieve the above objectives is: a quick-release 3D printer nozzle structure, including an X-axis mounting plate, a heat sink, a throat, a heating block, and a nozzle. The bottom of the heat sink is fixedly connected to the throat, the bottom of the throat is fixedly connected to the heating block, and the nozzle is fixedly connected to the heating block. The heat sink and the X-axis mounting plate are connected by a quick-release structure. The quick-release structure includes a structural box, an elastic moving component, a screw, a conical push head, and a knob. The back of the heat sink is fixedly connected to the structural box. The elastic moving component is provided inside the structural box. A through hole is provided on the structural box to cooperate with the elastic moving component. The screw is threadedly connected to the structural box. The conical push head is provided inside the structural box to cooperate with the elastic moving component. The conical part of the conical push head is close to the elastic moving component. The bottom surface of the conical push head is fixedly connected to the screw. The outer end of the screw is fixedly connected to the knob.

[0005] The X-axis mounting plate is provided with a mounting groove that mates with the structural box. The inner wall of the mounting groove is provided with a limiting hole corresponding to the through hole. The top of the elastic moving member passes through the through hole and is located in the limiting hole.

[0006] In the above technical solution, the structural box is provided with multiple sets of elastic moving parts, and each set of elastic moving parts is provided with a conical push head, and the multiple sets of conical push heads are fixedly connected by connecting columns.

[0007] In the above technical solution, the elastic moving component includes a limiting post, a spring, a limiting plate, and a sliding frame. The sliding frame is fixedly connected inside the structural box. The limiting post is slidably connected to the sliding frame. The limiting plate is fixedly connected to the limiting post. The spring is sleeved on the limiting post. One end of the spring is fixedly connected to the sliding frame, and the other end is fixedly connected to the limiting plate.

[0008] The inner end of the limiting post has a spherical structure, and the inner end of the limiting post abuts against the side of the conical push head. The top of the limiting post passes through the through hole and is located in the limiting hole.

[0009] In the above technical solution, a guide platform is fixedly connected inside the structural box, and a guide hole is provided on the guide platform, through which the connecting column passes.

[0010] In the above technical solution, L-shaped plates are fixedly connected to both sides of the structure box on the back of the heat sink. Each set of L-shaped plates on the X-axis mounting plate is provided with an L-shaped groove. One end of the L-shaped groove is provided with a sliding opening, and the other end is in a sealed state. When the L-shaped plate is fully fitted into the L-shaped groove, the through hole corresponds to the limiting hole.

[0011] The beneficial effects of this utility model are as follows: When disassembling the nozzle from the X-axis mounting plate, the knob can be turned to drive the conical push head to move outward. In this way, the pushing distance of the conical push head on the limiting post becomes smaller and smaller. With the elastic force of the spring, the limiting post can be disengaged from the limiting hole, and the nozzle can be disassembled from the X-axis mounting plate. The disassembly is simple and convenient and does not require the use of tools. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Please see Figures 1-7 A quick-release 3D printer nozzle structure includes an X-axis mounting plate 100, a heat sink 201, a throat 202, a heating block 203, and a nozzle 204. The bottom of the heat sink 201 is fixedly connected to the throat 202, the bottom of the throat 202 is fixedly connected to the heating block 203, and the nozzle 204 is fixedly connected to the heating block 203.

[0022] The aforementioned heat sink 201 is connected to the X-axis mounting plate 100 via a quick-release structure. In this embodiment, the quick-release structure includes a structural box 301, elastic moving parts 302, a screw 303, a conical push head 304, and a knob 305. That is, the structural box 301 is fixedly connected to the back of the heat sink 201, and the structural box 301 contains multiple sets of elastic moving parts 302. Specifically, the elastic moving parts 302 include a limiting post 3021, a spring 3022, and a limiting plate 302. 3. Sliding frame 3024: A sliding frame 3024 is fixedly connected inside the structural box 301. A limiting post 3021 is slidably connected to the sliding frame 3024. A limiting plate 3023 is fixedly connected to the limiting post 3021. A spring 3022 is sleeved on the limiting post 3021. One end of the spring 3022 is fixedly connected to the sliding frame 3024, and the other end is fixedly connected to the limiting plate 3023. In this way, the elastic force of the spring 3022 can drive the limiting post 3021 to move into the structural box 301.

[0023] In addition, each of the limiting posts 3021 that are matched with each set of elastic moving parts 302 on the structural box 301 is provided with a through hole 3025. That is to say, when the limiting post 3021 is subjected to outward pressure, the limiting post 3021 can pass through the through hole 3025 and stretch the spring 3022.

[0024] Furthermore, the structural box 301 is also threadedly connected to a screw 303. Inside the structural box 301, each set of elastic moving parts 302 is equipped with a conical push head 304. The conical tip of the push head 304 is close to the elastic moving part 302. The inner end of the limiting post 3021 of the elastic moving part 302 abuts against the side of the push head 304. The bottom surface of the push head 304 adjacent to the screw 303 is fixedly connected to the screw 303. A knob 305 is fixedly connected to the outer end of the screw 303. Multiple sets of push heads 304 are fixedly connected through connecting posts 306. Thus, when the knob 305 is rotated, it can... The screw 303 moves linearly in a spiral motion, simultaneously driving each set of conical push heads 304 to move linearly. When the bottom surface of the conical push head 304 gradually approaches the bottom end of the limiting post 3021, the conical push head 304 can provide pressure to the limiting post 3021, causing the limiting post 3021 to pass through the through hole 3025 and stretch the spring 3022. Conversely, when the screw 303 drives the bottom surface of the conical push head 304 to gradually move away from the limiting post 3021, the pressure on the limiting post 3021 will be gradually released, causing the limiting post 3021 to move inward from the through hole 3025 under the elastic force of the spring 3022.

[0025] Furthermore, to reduce the friction between the limiting post 3021 and the conical push head 304, the inner end of the limiting post 3021 adopts a spherical structure;

[0026] To accommodate the above structure, the X-axis mounting plate 100 is provided with a mounting groove 101 for the mating structure box 301. The inner wall of the mounting groove 101 is provided with a limiting hole 102 corresponding to the through hole 3025. The top of the limiting post 3021 of the elastic moving member 302 passes through the through hole 3025 and can be located in the limiting hole 102. In this way, the nozzle can be connected to the X-axis mounting plate 100. When disassembling, the above operation can be performed to make the limiting post 3021 come out of the limiting hole 102.

[0027] Ideally, a guide platform 307 is fixedly connected inside the structural box 301. The guide platform 307 is provided with a guide hole, through which the connecting column 306 passes. The guide platform 307 guides the movement of the conical push head 304, ensuring the stability of the movement of the conical push head 304 and avoiding deformation.

[0028] Furthermore, L-shaped plates 308 are fixedly connected to both sides of the structure box 301 on the back of the heat sink 201. Each set of L-shaped plates 308 on the X-axis mounting plate 100 is provided with an L-shaped groove 103. One end of the L-shaped groove 103 is provided with a sliding opening, and the other end is sealed. When the L-shaped plate 308 is fully fitted into the L-shaped groove 103, the through hole 3025 corresponds to the limiting hole 102. By setting the L-shaped plate 308, the installation stability of the nozzle and the X-axis mounting plate 100 can be enhanced. When installing the nozzle and the X-axis mounting plate 100, it is only necessary to fully insert the L-shaped plate 308 into the L-shaped groove 103 to achieve the correspondence between the through hole 3025 and the limiting hole 102, making the operation more convenient.
