Description

Technical Field

[0001] This utility model relates to the field of 3D printing technology, specifically to a 3D printing material conveying device. Background Technology

[0002] With the continuous development and widespread application of 3D printing technology, the material delivery process plays a crucial role in printing quality and efficiency. Traditional 3D printing material delivery devices have some significant shortcomings.

[0003] Firstly, in terms of conveying efficiency, many existing devices use a relatively conventional roller structure, which simply relies on friction to push the 3D printing material toward the heating nozzle. This limits the speed of the material during conveying, making it difficult to meet the needs of some application scenarios with high printing efficiency requirements, such as the rapid printing of large-scale industrial parts.

[0004] Secondly, in terms of driving force, conventional delivery methods have relatively low driving force on materials. When encountering 3D printing materials that are hard and have poor flexibility, delivery jams or even failure to deliver normally often occur, which seriously affects the continuity and stability of printing. Some high-strength engineering plastic printing materials are prone to such problems.

[0005] Furthermore, traditional conveying devices have poor adaptability to 3D printing materials of different shapes and properties, making it difficult to achieve efficient conveying of diverse materials through simple structural adjustments. These problems limit the expansion and application of 3D printing technology in more fields, necessitating a 3D printing material conveying device that can effectively improve conveying efficiency and driving force while possessing better material adaptability. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a 3D printing material conveying device.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows:

[0008] A 3D printing material delivery device includes a fixed frame plate, wherein two rotating rollers inside the fixed frame plate drive the 3D printing material toward a heating nozzle;

[0009] At least one inclined plate is fixed to the periphery of the rotating roller. A tangent is formed at the contact point between the inclined plate and the rotating roller. The angle between the tangent and the inclined plate in the direction of the heating nozzle is an acute angle.

[0010] The inclined fixing plate is located at the end away from the rotating roller and on the extension line of the inclined fixing plate to fix the material feeding plate.

[0011] Preferably, the angle between the tangent towards the heating nozzle and the material feeding plate is 30-60 degrees, and the material feeding plate is made of rubber.

[0012] Preferably, one of the rotating rollers is driven by a drive motor, which is fixed to a fixed frame plate, and the output end of the drive motor is fixedly connected to one end of the rotating roller that passes through the fixed frame plate.

[0013] Preferably, one end of the other rotating roller passing through the fixed frame plate is fixed with an "I"-shaped rotating shaft one, and an "I"-shaped rotating shaft two rotates on the fixed frame plate and on the same side as the "I"-shaped rotating shaft one. The "I"-shaped rotating shaft one and the "I"-shaped rotating shaft two are driven by a transmission belt. A gear is fixed at the end of one of the rotating rollers away from the drive motor, and a toothed ring that meshes with the gear is fixedly sleeved on the circumference of the "I"-shaped rotating shaft two.

[0014] Preferably, the outer diameter of the toothed ring and the gear are the same, and the size of the tooth opening is the same.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model makes the angle between the tangent towards the heating nozzle and the inclined fixed plate acute, which enables the material feeding plate to quickly move the 3D printing material towards the heating nozzle when the 3D printing material is being transported, thereby improving the transport efficiency.

[0017] 2. By setting up a material feeding plate, the present invention can deform and squeeze the 3D printing material when it comes into contact with the 3D printing material, thereby driving the 3D printing material to move towards the heating nozzle, so that the conveying device has a large driving force on the 3D printing material.

[0023] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0024] Example

[0025] like Figure 1-3 As shown, a 3D printing material conveying device includes a fixed frame plate 1, and two rotating rollers 2 inside the fixed frame plate 1 drive the 3D printing material to move toward the heating nozzle.

[0026] At least one inclined plate 3 is fixed on the periphery of the rotating roller 2. A tangent is formed at the contact point between the inclined plate 3 and the rotating roller 2. The angle between the tangent towards the heating nozzle and the inclined plate 3 is an acute angle.

[0027] The inclined plate 3 is used to fix the material feeding plate 4 at the end away from the rotating roller 2 and on the extension line of the inclined plate 3.

[0028] This invention makes the angle between the tangent direction towards the heating nozzle and the inclined fixed plate 3 acute, which enables the material feeding plate 4 to quickly move the 3D printing material towards the heating nozzle when the 3D printing material is being transported, thereby improving the transport efficiency.

[0029] This utility model provides a material feeding plate 4. Since the material feeding plate 4 is deformable, it can deform and squeeze the 3D printing material when it comes into contact with the 3D printing material, driving the 3D printing material to move towards the heating nozzle, so that the conveying device has a large driving force on the 3D printing material.

[0030] The angle between the tangent towards the heating nozzle and the material feeding plate 4 is 30-60 degrees, and the material feeding plate 4 is made of rubber.

[0031] By setting the angle between the tangent towards the heating nozzle and the feeding plate 4 to 30-60 degrees, better feeding can be achieved within the 30-60 degree range, resulting in better conveying effect.

[0032] One of the rotating rollers 2 is driven by a drive motor 5, which is fixed on the fixed frame plate 1, and the output end of the drive motor 5 is fixedly connected to one end of the rotating roller 2 that passes through the fixed frame plate 1.

[0033] By setting the drive motor 5, the rotating roller 2 can be driven;

[0034] Another rotating roller 2 passes through one end of the fixed frame plate 1 and is fixed with an I-shaped rotating shaft 6. An I-shaped rotating shaft 7 rotates on the fixed frame plate 1 on the same side as the I-shaped rotating shaft 6. The I-shaped rotating shaft 6 and the I-shaped rotating shaft 7 are driven by a transmission belt 8. A gear 10 is fixed at the end of one rotating roller 2 away from the drive motor 5. A toothed ring 9 that meshes with the gear 10 is fixedly sleeved on the periphery of the I-shaped rotating shaft 7.

[0035] When using the 3D printing material conveying device of this utility model, the 3D printing material is first passed through the gap between the two rotating rollers 2. Then, the drive motor 5 is started, which drives one of the rotating rollers 2 to rotate counterclockwise. At this time, the inclined fixed plate 3 and the material feeding plate 4 will rotate counterclockwise with the rotating roller 2. Due to the combined use of the "I" shaped rotating shaft 1 6, "I" shaped rotating shaft 2 7, transmission belt 8, toothed ring 9 and gear 10, when one of the rotating rollers 2 rotates counterclockwise, it can drive the gear 10 to rotate counterclockwise. Since the gear 10 and the toothed ring 9 are meshed, the counterclockwise rotation of the gear 10 will drive the toothed ring 9 to rotate clockwise. The clockwise rotation of the toothed ring 9, through the combined use of the "I" shaped rotating shaft 1 6, "I" shaped rotating shaft 2 7 and transmission belt 8, can drive the other rotating roller 2 to rotate clockwise. The clockwise rotation of the other rotating roller 2 will drive the inclined fixed plate 3 and the material feeding plate 4 on it to rotate clockwise, thereby conveying the 3D printing material to the heating nozzle.

[0036] The outer diameters of the gear ring 9 and the gear 10 are the same, and the tooth openings are the same size.

[0037] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
