The nozzle component of a stable and high-speed 3D printer can improve the printing quality and meet the hardware problems of the printing performance required by various consumables on the market. A larger extrusion flow rate should be matched with a faster extrusion speed. Improving and creating a new printing nozzle can enhance the user experience of high-speed 3D printing.
[0003] For the overall size and quality of the extrusion component, the integrated extrusion mechanism will not have a plugging phenomenon during operation, will not cause loss to the printing platform, and only an efficient extrusion mechanism can adapt to a higher printing speed.
[0004] The extrusion component is the core of the nozzle component. A high-flow nozzle must be adapted to a high-efficiency extrusion component. If the extrusion force is insufficient, it will affect the printing effect.
[0005] The core of the extrusion component is the extruder and the extrusion gear. Different forms of extrusion have different effects on the most critical extrusion force. During the printing process, the nozzle is in a fast-moving state. Coupled with the extrusion mechanism continuously extruding the moving consumable, and the consumable swinging closely behind. If the consumable is to be kept in the same position in the nozzle component all the time, the traditional nozzle component uses a tight extrusion mechanism, which is prone to problems such as the consumable not being able to enter the heating block normally during the feeding process and the spontaneous loss of the consumable.
[0006] Therefore, an extrusion mechanism that requires a large extrusion force, is adapted to the flow rate of the nozzle, and has a better printing effect for the nozzle component is developed. The utility model provides an extrusion kit for a 3D printer. Summary of the Invention

By starting the extrusion motor to work, the extrusion motor controls the rotation of multiple planetary gears, so that the consumable is discharged from the gap between multiple extrusion gears, in order to solve the problem that a high-flow nozzle must be adapted to a high-efficiency extrusion component. If the extrusion force is insufficient, it will affect the printing effect, and the traditional nozzle component uses a tight extrusion mechanism, which is prone to problems such as the consumable not being able to enter the heating block normally during the feeding process and the spontaneous loss of the consumable.

Specific embodiments
[0028] The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustration and explanation of the present utility model, and are not used to limit the present utility model.
[0029] Referring to the attached Figure 1 - attached Figure 4 , a 3D printer extrusion kit provided by the present utility model includes
[0030] An extrusion motor 1, with a planetary gear mounting plate 2 provided on the front side of the extrusion motor 1, and a driving gear 3 provided inside the planetary gear mounting plate 2;
[0031] An extrusion gear 4, with a compression screw 5 provided on one side of the extrusion gear 4;
[0032] An extrusion box housing 6, which is provided in front of the extrusion gear 4, with a nozzle handle 7 provided on the rear side of the extrusion box housing 6, and the nozzle handle 7 is provided on one side of the planetary gear mounting plate 2;
[0033] In this implementation, by the user starting the extrusion motor 1 to work, the extrusion motor 1 controls the rotation of multiple planetary gears 9, so that the consumable material is discharged from the gap between the multiple extrusion gears 4;
[0034] Among them, in order to achieve the purpose of tight extrusion, the present device is implemented by the following technical solutions: A compression screw 5 is provided on one side of the planetary gear mounting plate 2, an extrusion gear 4 is provided inside the planetary gear mounting plate 2, an extrusion end bearing 8 is provided in front of the extrusion gear 4, multiple planetary gears 9 are provided on the rear side of the extrusion gear 4, fixing screws 10 are embedded inside multiple planetary gears 9, the rear ends of multiple fixing screws 10 are respectively embedded inside the planetary gear mounting plate 2, a first extrusion follower gear bearing 11 is embedded inside the nozzle handle 7, a second extrusion follower gear bearing 12 is embedded inside the nozzle handle 7, the second extrusion follower gear bearing 12 is provided at the bottom of two first extrusion follower gear bearings 11, and an isolation spring column 13 is provided inside the nozzle handle 7, and the isolation spring column 13 is sleeved outside the compression screw 5;
[0035] The working mechanism of the gear motor is delicate and efficient. When the extrusion motor 1 starts and rotates, the drive gear 3 immediately activates the three planetary gears 9 in the extrusion mechanism. These planetary gears 9 are ingeniously arranged within the planetary gear mounting plate 2. They not only rotate around their own axes but also revolve along the rotation path of the drive gear 3, thereby jointly driving the central extrusion gear 4 to start rotating. On the planetary gears 9, extrusion driving gears are installed, and they rotate along with the synchronous movement of the planetary gears 9. These driving gears mesh tightly with the specially designed second extrusion follower gear on the handle. The second extrusion follower gear adopts a toothless processing technology. This innovative design significantly reduces the wear on the printing consumables and extends the service life of the consumables. As the first extrusion follower gear and the second follower gear rotate towards the center, their close cooperation forms a powerful extrusion force in the extrusion groove of the gear. This force effectively extrudes the printing consumables evenly and stably from the gap between the two extrusion gears 4. At the same time, the design of using double follower gears further enhances the stability of the system and reduces the risk of the consumables being accidentally pulled and broken due to uneven force.
[0036] The usage process of the present utility model is as follows: By the user starting the extrusion motor 1 to work, the extrusion motor 1 controls the rotation of multiple planetary gears 9, enabling the consumables to be discharged from the gap between the multiple extrusion gears 4. The working mechanism of the gear motor is delicate and efficient. When the extrusion motor 1 starts and rotates, the drive gear 3 immediately activates the three planetary gears 9 in the extrusion mechanism. These planetary gears 9 are ingeniously arranged within the planetary gear mounting plate 2. They not only rotate around their own axes but also revolve along the rotation path of the drive gear 3, thereby jointly driving the central extrusion gear 4 to start rotating.
