[0002] 3D printers, also known as additive manufacturing equipment, create three-dimensional objects by stacking materials layer by layer. Their core principle is to create physical objects from digital three-dimensional models (usually STL or 3MF files) by stacking materials layer by layer.
[0003] Some existing 3D printers use pellet material, which is fed to the print head by being put into a pellet cylinder. However, the current cylinder size and internal capacity are fixed. When the printing material is too large, it needs to be added frequently during printing. To address this issue, we propose a pellet cylinder suitable for 3D printing equipment. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a granular material cylinder suitable for 3D printing equipment.

An adjusting feed cylinder is sleeved on top of the fixed feed cylinder, and a guide ring is fixedly connected to the inner side of the upper part of the adjusting feed cylinder. A guiding mechanism is fixedly connected to the lower part of the guide ring. A limit mechanism is fixedly connected to the surface of the adjusting feed cylinder, and a blocking mechanism is hinged to the upper part of the adjusting feed cylinder.
[0006] Preferably, the surface diameter of the adjusting cylinder is adapted to the surface diameter of the fixed cylinder, the inner wall diameter of the guide ring is smaller than the surface diameter of the fixed cylinder, and the surface of the guide ring is set as an inclined surface.
[0007] Preferably, the guiding mechanism includes guide columns, and multiple sets of guide columns are fixedly connected below the guide ring, and all sets of guide columns are inserted into the fixed plate, and the fixed plate is fixedly connected to the inner wall of the fixed cylinder.
[0008] Preferably, the guide post is cylindrical, and a limiting disk is fixedly connected to the lower end of the guide post, wherein the surface diameter of the guide post is smaller than the surface diameter of the limiting disk.
[0009] Preferably, the limiting mechanism includes a fixed frame, the surface of the adjusting cylinder is fixedly connected to the fixed frame, and the outer end of the fixed frame is threaded with a driving stud. The end of the driving stud is connected to one side of the connecting plate through a bearing, and the other side of the connecting plate is fixedly connected to an extrusion column.
[0010] Preferably, the shielding mechanism includes a shielding cover plate, the upper end of the adjusting cylinder is hinged to the shielding cover plate, and an observation window is installed at the center of the shielding cover plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This device guides the granules into the adjusting cylinder and the fixed cylinder by adjusting the guide ring fixed to the inner wall of the upper cylinder. The adjusting cylinder moves along the surface of the fixed cylinder, which facilitates the adjustment of the granule capacity and makes it easy to adjust according to the consumption of printing material. At the same time, by rotating the stud, the connecting plate drives the extrusion column to pass through the adjusting cylinder and abut against the surface of the fixed cylinder, which plays the role of limiting and fixing the cylinder and the adjusting cylinder.

[0016] 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.
[0017] Reference Figure 1-4 A pellet cylinder suitable for 3D printing equipment includes a printer stand 1, a print head 2 mounted on top of the printer stand 1, and a fixed pellet cylinder 3 connected to the upper side of the print head 2. An adjusting pellet cylinder 4 is sleeved on top of the fixed pellet cylinder 3. The internal capacity of the fixed pellet cylinder 3 and the adjusting pellet cylinder 4 can be adjusted by moving the adjusting pellet cylinder 4 along the surface of the fixed pellet cylinder 3. A guide ring 5 is fixedly connected to the upper inner side of the adjusting pellet cylinder 4, and a guide mechanism 6 is fixedly connected to the lower side of the guide ring 5. A limit mechanism 7 is fixedly connected to the surface of the adjusting pellet cylinder 4, and a blocking mechanism 8 is hinged to the upper part of the adjusting pellet cylinder 4.
[0018] Furthermore, refer to Figure 2 and Figure 3 It can be seen that the surface diameter of the adjusting cylinder 4 is matched with the surface diameter of the fixed cylinder 3, the inner wall diameter of the guide ring 5 is smaller than the surface diameter of the fixed cylinder 3, and the surface of the guide ring 5 is set as an inclined surface. The guide ring 5 can guide the action of the granular material.
[0019] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the guiding mechanism 6 includes a guide post 61. Multiple sets of guide posts 61 are fixedly connected to the lower part of the guide ring 5, and all sets of guide posts 61 are inserted into the fixed plate 62. The fixed plate 62 is fixedly connected to the inner wall of the fixed material cylinder 3. By sliding the guide post 61 along the inside of the fixed plate 62, it can play the role of limiting and guiding the adjustment of the material cylinder 4.
[0020] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the guide post 61 is cylindrical. By making the guide post 61 cylindrical, the wear between it and the fixing plate 62 can be reduced. The lower end of the guide post 61 is fixedly connected to the limiting plate 63. The surface diameter of the guide post 61 is smaller than the surface diameter of the limiting plate 63. The limiting plate 63 can limit the guide post 61.
[0021] Furthermore, refer to Figure 3 and Figure 4It can be seen that the limiting mechanism 7 includes a fixed frame 71. The fixed frame 71 is fixedly connected to the surface of the adjusting cylinder 4, and a drive stud 72 is threaded into the outer end of the fixed frame 71. The end of the drive stud 72 is connected to one side of the connecting plate 73 through a bearing. By rotating the drive stud 72, the connecting plate 73 and the extrusion column 74 can be easily moved. The other side of the connecting plate 73 is fixedly connected to the extrusion column 74. The extrusion column 74 passes through the adjusting cylinder 4 and extrudes the fixed cylinder 3, thereby limiting and fixing the cylinder 3 and the adjusting cylinder 4.
[0022] Furthermore, refer to Figure 1 and Figure 2 It can be seen that the shielding mechanism 8 includes a shielding cover plate 81. The upper end of the adjusting cylinder 4 is hinged to the shielding cover plate 81, and an observation window 82 is installed at the center of the shielding cover plate 81. The shielding cover plate 81 can be opened and closed easily through the hinged installation. At the same time, the internal functions of the fixed cylinder 3 and the adjusting cylinder 4 can be easily observed through the observation window 82.
[0023] Furthermore, refer to Figure 1 and Figure 2 It can be seen that a grip handle 83 is fixedly connected to the top of the cover plate 81, and the surface of the grip handle 83 is covered with an anti-slip rubber sleeve 84. By setting the cross-section of the grip handle 83 to U-shape, it is convenient to grip and drive the cover plate 81, and the anti-slip rubber sleeve 84 can increase the gripping and anti-slip effect.
[0024] Working principle: When this utility model is in use, if the fixed material cylinder 3 and the adjusting material cylinder 4 are being adjusted, according to the attached... Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4 By rotating the stud 72, the connecting plate 73 and the extrusion column 74 can be retracted into the fixed frame 71. At this time, pulling the adjusting cylinder 4 can move the adjusting cylinder 4 along the surface of the fixed cylinder 3. As the adjusting cylinder 4 moves, the guide ring 5 can drive the guide column 61 to move along the inside of the fixed plate 62. After the fixed cylinder 3 and the adjusting cylinder 4 are adjusted, rotating the stud 72 can push the connecting plate 73 and the extrusion column 74 to abut against the surface of the fixed cylinder 3, which can limit and fix the three adjusting cylinders 4. When feeding the granules, gripping the grip handle 83 can open the cover plate 81 and feed the granules into the fixed cylinder 3 and the adjusting cylinder 4. After feeding, pulling the grip handle 83 can reset the cover plate 81 and cover and protect the top of the adjusting cylinder 4. The above is the complete working principle of this utility model.
