Description

Technical Field

[0001] This utility model relates to the field of printing consumables technology, and in particular to a material extrusion device for the production of 3D printing consumables. Background Technology

[0002] 3D printing FDM filament is a relatively thin filament with large production volume and demand. The production of 3D printing filament requires the joint production of multiple equipment.

[0003] However, in the existing technology, there are problems with the extrusion and transportation of 3D printing consumables. The extrusion and transportation of consumables cannot be carried out at a uniform speed, resulting in uneven product density during printing, which affects the quality of the finished product. In addition, the long transportation distance may cause the material to cool and clump together. To address this, we propose a material extrusion device for the production of 3D printing consumables.

[0004] This invention provides a material extrusion device for the production of 3D printing consumables, which solves the above-mentioned technical problems.

[0005] The solution to the above-mentioned technical problems of this utility model is as follows: A material extrusion device for the production of 3D printing consumables includes a first pipe arranged horizontally, a first spiral arranged horizontally inside the first pipe, a power mechanism connected to the first spiral, a second pipe that is inclined and fixedly connected to the lower part of one end of the first pipe, a second spiral arranged inside the second pipe, a drive mechanism connected to the second spiral, heating tubes respectively sleeved on the outer walls of the first pipe and the second pipe, a protective tube arranged outside the heating tube, and a funnel-shaped feeder fixedly installed at the end of the first pipe.

[0006] Preferably, the power mechanism includes a first motor that is horizontally fixedly installed on the outer wall of the first pipe, and the output shaft of the first motor rotates through the first pipe and is fixedly connected to the first spiral.

[0007] Preferably, the driving mechanism includes a second motor fixedly installed on the outer wall of the second pipe, the output shaft of the second motor rotating through the second pipe and fixedly connected to the second spiral.

[0008] Preferably, a third motor is fixedly installed on the outer wall of the feeder, and a crushing roller is installed laterally inside the feeder.

[0009] Preferably, the transmission mechanism includes gears fixedly mounted on the outer wall of the crushing roller shaft, two gears meshing together, and the gears are located outside the feeder.

[0010] The beneficial effects of this utility model are:

[0011] 1. By setting up crushing rollers, the consumables entering the device are further crushed and transported by the first and second spirals. Finally, the consumables are transported at a constant speed through the lower uniform foundation of the second pipe, so that the consumables are evenly distributed and the product forming quality is improved.

[0012] 2. By setting up a heating tube, the consumables during the delivery process are kept warm, preventing them from cooling and clumping, thus ensuring the printing quality of the device.

The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0021] like Figure 1-3 As shown, this utility model discloses a material extrusion device for 3D printing consumables production, comprising a horizontally arranged first pipe 1, a first spiral 2 horizontally arranged inside the first pipe 1, the first spiral 2 being connected to a power mechanism, a second pipe 3 being inclinedly fixed and connected to the lower part of one end of the first pipe 1, a second spiral 4 being arranged inside the second pipe 3, the second spiral 4 being connected to a drive mechanism, heating tubes 5 being respectively sleeved on the outer walls of the first pipe 1 and the second pipe 3, and protective tubes 6 being arranged outside the heating tubes 5, and a funnel-shaped feeder 7 being fixedly installed at the end of the first pipe 1. This device automatically transports materials by setting the first spiral 2 and the second spiral 4, while simultaneously achieving uniform material conveying, ensuring uniform product density, and improving product production quality. Furthermore, the heating tubes 5 on the outer walls of the first pipe 1 and the second pipe 3 can heat and insulate the materials during transportation, preventing material from clumping inside the device and ensuring production quality. The protective tubes 6 outside the heating tubes 5 can reduce heat loss, protect the internal heating tubes 5, and prevent accidental contact with the heating tubes 5, thus improving safety.

[0022] Specifically, the power mechanism includes a first motor 8 that is horizontally fixedly installed on the outer wall of the first pipe 1. The output shaft of the first motor 8 rotates through the first pipe 1 and is fixedly connected to the first spiral 2. The first motor 8 drives the first spiral 2 to rotate to transport production materials.

[0023] More specifically, the drive mechanism includes a second motor 9 fixedly installed on the outer wall of the second pipe 3. The output shaft of the second motor 9 rotates through the second pipe 3 and is fixedly connected to the second spiral 4. The second motor 9 drives the second spiral 4 to rotate, conveying the production material downwards, and finally discharging it through the discharge port at the bottom of the second pipe 3.

[0024] Furthermore, a third motor 10 is fixedly installed on the outer wall of the feeder 7, and a crushing roller 11 is horizontally rotatably installed inside the feeder 7. The two crushing rollers 11 are connected by a transmission mechanism. The shaft of one of the crushing rollers 11 is fixedly connected to the third motor 10. The transmission mechanism includes a gear 12 fixedly installed on the outer wall of the shaft of the crushing roller 11. The two gears 12 are meshed and connected. The gear 12 is located outside the feeder 7. The third motor 10 indirectly drives the two crushing rollers 11 to rotate. The crushing rollers 11 are used to crush the material entering the feeder 7 to prevent the material from clumping and making it inconvenient to transport. At the same time, it ensures the uniform distribution of the material and improves the product quality.

[0025] Working principle:

[0026] The control and starting device is activated. The first motor 8 drives the first screw 2 to rotate, the second motor 9 drives the second screw 4 to rotate, and the third motor 10 directly drives the gear 12 and crushing roller 11 connected to it to rotate. Through the transmission of the two gears 12, it indirectly drives another crushing roller 11 to rotate synchronously. The heating tube 5 starts heating. The material is added into the feeder 7. After being crushed by the crushing roller 11, the material enters the first pipe 1 and is then conveyed into the second pipe 3 by the first screw 2. During the conveying process, the heating tube 5 works to heat and keep the material warm to prevent the material from clumping. Finally, the material is discharged from the lower end of the second pipe 3, realizing the extrusion of the material.
