Description

Technical Field

[0001] This utility model relates to an automatic docking powder dispensing unit. Background Technology

[0002] 3D printing metal powder materials typically involve a single sieving and mixing process. This involves sieving the metal powder using a powder sieve and then filling it into a powder mixer for mixing. This ensures that different batches of the same type of new or old powder are thoroughly and evenly mixed, guaranteeing the stability of the performance of 3D printed products from the same batch of metal powder materials.

[0003] A docking device is needed to connect the powder mixing equipment and the material discharge hopper. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned problems in the existing technology by proposing an automatic docking powder dispensing unit. The powder dispensing barrel has a docking structure at the discharge port, that is, the cylinder body and cylinder sleeve are an integral structure that can operate in a sealed manner from top to bottom. Powder passes through the cylinder body, and the cylinder body and the discharge port achieve automatic docking.

[0005] The purpose of this utility model can be achieved through the following technical solution: an automatic docking powder dispensing unit, characterized in that it includes a powder dispensing bucket, a support, a cylinder body, a cylinder sleeve, and a cylinder, wherein the powder dispensing bucket is fixed on the support, the upper end of the cylinder body is connected to the powder dispensing port of the powder dispensing bucket, the cylinder sleeve is fitted on the cylinder body and moves up and down along the cylinder body, and the cylinder is located between the cylinder body and the cylinder sleeve.

[0006] Furthermore, the cylinder body has a first groove on its outer wall and a sealing ring is fitted therein.

[0007] Furthermore, the cylinder outer wall has a second groove, and the cylinder liner inner wall has a guide member that is fitted into the second groove.

[0008] Furthermore, the cylinder liner has a third groove on its uppermost sidewall, and the cylinder body has a guide member that is fitted into the third groove.

[0009] Furthermore, the cylinder liner is characterized by having a pressure plate at its uppermost end.

[0010] Furthermore, the cylinder is characterized by having a speed regulating valve.

[0011] Furthermore, the cylinder is equipped with a limiter.

[0012] Compared with the prior art, the advantages of this application are: the discharge port of its powder discharge hopper is equipped with a docking structure, that is, the cylinder body and the cylinder liner are an integral structure that can be sealed from top to bottom. The powder passes through the cylinder body and the cylinder body and the discharge port are automatically docked. Attached Figure Description

[0017] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0018] like Figure 1-3 As shown, an automatic powder-discharging unit is characterized by comprising a powder-discharging bucket 3, a support 2, a cylinder body 11, a cylinder sleeve 14, and a cylinder 15. The powder-discharging bucket 3 is fixed on the support 2. The upper end of the cylinder body 11 is connected to the powder-discharging port of the powder-discharging bucket 3. The cylinder sleeve 14 is fitted onto the cylinder body 11 and moves up and down along the cylinder body 11. The cylinder 15 is located between the cylinder body 11 and the cylinder sleeve 14. Further, the cylinder body 11 has a first groove 16 on its outer wall and a sealing ring 161 is embedded therein. The cylinder body and cylinder sleeve are an integral structure that can operate with a sealed top and bottom. Powder passes through the cylinder body, and the cylinder body and the powder-discharging port are automatically connected. The sealing ring 161 ensures the sealing of the internal and external cavities during operation, preventing leakage.

[0019] Furthermore, the cylinder body 11 has a second groove 171 on its outer wall, and the cylinder sleeve 14 has a guide member 17 that is fitted into the second groove 171 on its inner wall.

[0020] Furthermore, the cylinder liner 14 has a third groove 131 on its uppermost sidewall, and the cylinder body 11 has a guide member 13 that is fitted into the third groove 131. The guide member 13 and the guide member 17 make the structure more stable in operation.

[0021] Furthermore, the cylinder liner 14 is characterized by having a pressure plate 12 at its uppermost end. The pressure plate 12 serves as a buffer.

[0022] Furthermore, the cylinder 15 is characterized by having a speed regulating valve 19. The speed regulating valve 19 is used to regulate the operating speed of the cylinder 15.

[0023] Furthermore, the cylinder 15 is provided with a limiter 151. The limiter 151 is used to limit the maximum operating position of the cylinder 15.

[0024] This material feeding unit has a material inlet docking module 1 between the powder feeding bucket 3 and the powder mixing bucket (i.e., the structure of cylinder liner 14, cylinder body 11 and cylinder 15, which is an integral structure), which can realize the automatic docking of the material feeding inlet and the powder mixing bucket.

[0025] The above-described technical solution of this utility model addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The parts not covered in this application's technical solution are the same as or can be implemented using existing technologies, and will not be described in detail here.

[0026] The technical solutions in the above embodiments have clearly and completely described the content of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
