Description

Technical Field

[0001] This utility model relates to the field of 3D printer nozzle installation technology, and in particular to a quick-release 3D printer nozzle installation and positioning structure. Background Technology

[0002] In the daily use of 3D printers, problems such as nozzle clogging, loosening, and nozzle wear are common, necessitating nozzle replacement. Traditionally, nozzle modules are fixed to a mounting base with bolts, and the mounting base is fixed to the X-axis slider with bolts.

[0003] Most existing printhead mounting structures use bolts for connection and fixation. When replacing them, multiple bolts need to be unscrewed with tools to disassemble them, which is relatively cumbersome and inefficient. In addition, existing printhead mounting structures often do not have height adjustment capabilities, making it impossible to adjust the installation height of the 3D printer printhead as needed during use. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a quick-release 3D printer nozzle mounting and positioning structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A quick-release 3D printer nozzle mounting and positioning structure includes an inverted U-shaped slider connecting seat, a nozzle mounting seat connected to the slider connecting seat via a height adjustment component, and a 3D printer nozzle assembly fixed on the nozzle mounting seat via a mounting and positioning component. The installation and positioning assembly includes an installation hole at the center of the nozzle mounting base, two symmetrical grooves in the installation hole, two telescopic rods fixed in the two grooves, two connecting plates fixed to the outer walls of the telescopic ends of the two telescopic rods, two springs sleeved on the telescopic ends of the two telescopic rods, two positioning beads fixed to the outer walls of opposite sides of the two connecting plates, and two unlocking rods welded to the two connecting plates.

[0006] As a further description of the above technical solution, the upper part of the 3D printer nozzle assembly is symmetrically provided with two positioning slots that are adapted to the positioning beads, and the two positioning beads are respectively engaged in the two positioning slots. The top of the nozzle mounting base is symmetrically provided with two slides, the two slides are respectively connected to two inner grooves, and the outer walls of the two unlocking rods are respectively slidably connected to the inner walls of the two slides.

[0007] As a further description of the above technical solution, the height adjustment assembly includes a slide groove formed on one side of the slider connecting seat, an adjusting screw rotatably installed in the slide groove, an adjusting block threadedly connected to the adjusting screw, and a rotating cap fixedly connected to the outer wall of the bottom end of the adjusting screw.

[0008] As a further description of the above technical solution, the outer wall of the adjusting block is slidably connected to the inner wall of the sliding groove, and the adjusting block and the nozzle mounting base are fixedly connected to each other.

[0009] As a further description of the above technical solution, two linear guide rails are symmetrically fixed on the inner sidewalls of both sides of the slider connecting seat, and two guide blocks are symmetrically welded on the outer sidewalls of both sides of the nozzle mounting seat, and the four guide blocks are slidably connected to the four linear guide rails respectively.

[0010] As a further description of the above technical solution, the lower part of the adjusting screw is threaded with a locking nut, and the locking nut forms a tight fit with the bottom surface of the slider connecting seat.

[0011] The beneficial effects of this utility model are as follows: 1. Equipped with an installation positioning component, it eliminates the original bolt fixing method. When the 3D printer nozzle assembly is installed into the mounting hole, the two positioning balls will automatically spring into the two positioning slots to achieve an automatic locking and positioning effect, making installation convenient and quick. In subsequent disassembly, you only need to push the two unlocking rods by hand to ensure that the two positioning balls retract into the two inner grooves to quickly remove the 3D printer nozzle assembly, thereby effectively improving the disassembly efficiency of the 3D printer nozzle assembly. 2. It is equipped with a height adjustment component, which allows for flexible adjustment of the installation height of the 3D printer printhead assembly mounted on the printhead mounting base, thereby better meeting the printing needs of different products.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Example 1, referring to Figure 1-5 A quick-release 3D printer nozzle mounting and positioning structure includes an inverted U-shaped slider connecting seat 1. During installation, the slider connecting seat 1 is fixedly connected to the X-axis slider with bolts. The nozzle mounting seat 2 is connected to the slider connecting seat 1 through a height adjustment component. The 3D printer nozzle assembly 3 is fixed on the nozzle mounting seat 2 through a mounting and positioning component. Specifically, the installation positioning component includes a mounting hole 4 at the center of the nozzle mounting base 2, two inner grooves 5 symmetrically opened in the mounting hole 4, two telescopic rods 6 fixed in the two inner grooves 5 in sequence, two connecting plates 7 fixed in sequence to the outer wall of the telescopic ends of the two telescopic rods 6, two springs 8 sequentially sleeved on the telescopic ends of the two telescopic rods 6, two positioning beads 9 sequentially fixed on the outer wall of opposite sides of the two connecting plates 7, and two unlocking rods 18 sequentially welded to the two connecting plates 7. Furthermore, the upper part of the 3D printer nozzle assembly 3 is symmetrically provided with two positioning slots 10 that are adapted to the positioning beads 9. The two positioning beads 9 are respectively engaged in the two positioning slots 10. The top of the nozzle mounting base 2 is symmetrically provided with two slides 17. The two slides 17 are respectively connected to two inner grooves 5, and the outer walls of the two unlocking rods 18 are respectively slidably connected to the inner walls of the two slides 17. The working principle of this embodiment is as follows: First, during installation, simply insert the 3D printer nozzle assembly 3 upwards into the mounting hole 4. During installation, the nozzle head will press against the two positioning beads 9. Under the extension and retraction of the two telescopic rods 6, the two positioning beads 9 will retract into the two inner grooves 5, causing the two springs 8 to be compressed. When the two positioning slots 10 at the nozzle head are aligned with the two inner grooves 5, the two positioning beads 9 are no longer compressed. Then, under the elastic force of the two springs 8, the two positioning beads 9 will be automatically pushed into the two positioning slots 10 by the two telescopic rods 6 to achieve a locking effect. Second, during subsequent disassembly, simply push the two unlocking rods 18 by hand to ensure that the two positioning beads 9 retract into the two inner grooves 5, and the 3D printer nozzle assembly 3 can be quickly removed, thereby effectively improving the disassembly efficiency of the 3D printer nozzle assembly 3.

[0016] Example 2, refer to Figure 2 , Figure 5 and Figure 6 This embodiment is an optimization based on embodiment 1. Specifically, the height adjustment component includes a slide groove opened on one side of the slider connecting seat 1, an adjusting screw 11 rotatably installed in the slide groove, an adjusting block 12 threadedly connected to the adjusting screw 11, and a rotating cap 13 fixedly connected to the outer wall of the bottom end of the adjusting screw 11. Furthermore, the outer wall of the adjusting block 12 is slidably connected to the inner wall of the slide groove, and the adjusting block 12 is fixedly connected to the nozzle mounting base 2. Two linear guide rails 15 are symmetrically fixed on the inner side walls of both sides of the slider connecting base 1, and two guide blocks 16 are symmetrically welded on the outer side walls of both sides of the nozzle mounting base 2. The four guide blocks 16 are slidably connected to the four linear guide rails 15 respectively. In this way, through the guiding cooperation between the four guide blocks 16 and the four linear guide rails 15, the stability of the linear movement of the adjusting block 12, which is threadedly connected to the adjusting screw 11, can be guaranteed. Furthermore, the lower part of the adjusting screw 11 is threaded with a locking nut 14, which forms a tight fit with the bottom surface of the slider connecting seat 1. After the adjusting screw 11 has rotated, the adjusting screw 11 can be locked by tightening the locking nut 14, thereby preventing it from accidentally reversing under force.

[0017] The working principle of this embodiment is as follows: the adjusting screw 11 can be driven to rotate forward and backward by the rotating cap 13. Then, under the guidance of the guide block 16 and the linear guide rail 15, the adjusting block 12, which is threadedly connected to the adjusting screw 11, will drive the nozzle mounting base 2 to move up and down. In this way, the installation height of the 3D printer nozzle assembly 3 installed on the nozzle mounting base 2 can be flexibly adjusted, thereby better meeting the printing needs of different products.
