[0052] In order to make the technical problems, technical schemes and beneficial effects to be solved by the utility model more clearly understood, the utility model will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model, and are not used to limit the utility model.

[0053] Please refer to Figure 1 and Figure 2The full-automatic metal powder filling production line comprises a conveying assembly 10, a filling assembly 20 and a hole sealing assembly 30. The conveying assembly 10 is provided with a linear conveying part arranged horizontally on the top and used for vertically inserting the cylindrical shell 40. The filling assembly 20 is fixedly connected with the conveying assembly 10 and is provided with a material injection part above the linear conveying part. The filling assembly 20 can fill the metal powder into the cylinder cavity of the cylindrical shell 40 through the material injection part after the cylindrical shell 40 is moved below the material injection part. The hole sealing assembly 30 is fixedly connected with the conveying assembly 10 and is located behind the linear conveying part. The hole sealing assembly 30 can seal the cylindrical shell 40 filled with the metal powder.

[0054] Specifically, the working process is that the linear conveying part is provided with an inlet end and an outlet end. The cylindrical shell 40 to be filled is placed on the linear conveying part in a vertical state by a robot or manually, and the cylinder cavity of the cylindrical shell 40 is open upward. The linear conveying part moves the cylindrical shell 40 below the filling assembly 20 and stops. The filling assembly 20 injects the metal powder into the cylinder cavity of the cylindrical shell 40 through the material injection part. After the injection of the metal powder is completed, the cylindrical shell 40 continues to move to the hole sealing assembly 30 and stops. The hole sealing assembly 30 injects the molten wax into the top of the cylindrical shell 40. After the molten wax is solidified, a fixed wax block is formed and the hole is sealed. Subsequently, the filled cylindrical shell 40 is taken out at the outlet end.

[0055] In the embodiment, in order to increase the work efficiency, the filling assembly 20 and the hole sealing assembly 30 can work synchronously.

[0056] Compared with the prior art, the full-automatic metal powder filling production line provided by the embodiment can ensure the linear and continuous transmission of the cylindrical shell 40 through the linear conveying part provided by the conveying assembly 10, and the cylindrical shell 40 can pass through and correspond to the filling assembly 20 and the hole sealing assembly 30 in sequence, so that the filling of the metal powder and the filling of the sealing material are realized in sequence. The automation of the metal powder filling is realized, the work efficiency can be effectively improved, the manpower can be saved, and the practicability is high.

[0057] It should be further pointed out that after the hole is sealed by the molten wax, the transmission cooling needs to be performed. At this time, the high-temperature fire match can be placed in the opening of the cylindrical shell 40 by a robot, so that the high-temperature fire match is fixed in the final solid wax block.

[0058] In some embodiments, the conveying assembly 10 can adopt the structure as shown in Figures 1 to 2 Figures 1 to 2 ​The conveying assembly 10 includes a conveyor belt 11 and limiting blocks 12. The conveyor belt 11 has an annular conveying surface, and the top end of the annular conveying surface extends horizontally. Multiple limiting blocks 12 are provided, and each limiting block 12 is spaced around the annular conveying surface and connected to the annular conveying surface. Each limiting block 12 is provided with an insertion hole 13 for inserting the cylindrical outer shell 40.

[0059] The limiting blocks 12 located at the top of the conveyor belt 11 form a linear conveying section.

[0060] The conveyor belt 11 can drive each limiting block 12 to rotate via the annular conveying surface, and the horizontal extension surface at the top of the annular conveying surface can ensure that the limiting blocks 12 in the area are transmitted in the horizontal direction, thereby ensuring the adaptation to the filling component 20 and the sealing component 30. Correspondingly, the insertion holes 13 provided on each limiting block 12 can ensure the insertion and fixation of the cylindrical outer shell 40, thereby ensuring the filling effect of the metal powder.

[0061] The conveyor belt 11 may include a frame, multiple horizontally spaced conveyor rollers rotatably mounted on the frame, a belt wound in a ring around each conveyor roller, and a servo motor poweredly connected to one of the conveyor rollers. The ring conveyor surface is a belt, which is prior art and will not be described in detail here.

[0062] In some embodiments, the aforementioned limiting block 12 may employ, as follows: Figures 1 to 2 The structure shown. See also Figures 1 to 2 Each limiting block 12 has multiple insertion holes 13, and each insertion hole 13 is spaced apart along the width direction of the conveyor belt 11, which can ensure an increase in the number of cylindrical shells 40 for each metal powder filling and sealing, thereby improving production efficiency.

[0063] In some embodiments, the filling component 20 described above may employ, for example... Figure 1 and Figure 3 The structure shown. See also Figure 1 and Figure 3 The filling assembly 20 includes a first guide rod 21, a first slide block 22, a first telescopic structure 23, a filling tube 24, and a filling structure 25. Two first guide rods 21 are provided, distributed on both sides of the linear conveying section and both arranged vertically. The first slide block 22 is located above the linear conveying section and is slidably connected to each of the first guide rods 21. The first telescopic structure 23 can drive the first slide block 22 to move up and down. The filling tube 24 is arranged vertically, and its top end is connected to the first slide block 22. The filling tube 24 can extend into the cylindrical outer shell 40 after moving downwards with the first slide block 22. The filling structure 25 is disposed on the first slide block 22 and communicates with the top end of the filling tube 24, enabling the transfer of metal powder to the filling tube 24.

[0064] The first sliding seat 22 can be driven by the first telescopic structure 23 to move up and down, thereby driving the filler pipe 24 and the filler structure 25 to move up and down. Each time the up and down movement is completed, the metal powder filling is completed, which can ensure the filling effect of the metal powder and can also adapt to the automatic filling of the metal powder.

[0065] Specifically, in the metal powder filling process, the first sliding seat 22 is driven by the first telescopic structure 23 to rise to the top position of the first guide rod 21 as the initial position. When the limiting block 12 carrying the cylindrical shell 40 moves to the lower side of the filler pipe 24, the conveying belt 11 stops. At this time, the first sliding seat 22 drives the filler pipe 24 to move downward to the bottom end of the filler pipe 24, which extends into the cylinder cavity of the cylindrical shell 40. Then, the first sliding seat 22 moves upward, and the filler structure 25 is opened. The filling of the metal powder is completed before the filler pipe 24 moves out of the cylindrical shell 40.

[0066] In the embodiment, the filler pipe 24 can be provided in multiple numbers, and each filler pipe 24 corresponds to the insertion hole 13 on each limiting block 12. Meanwhile, the filler structure 25 can also be provided in multiple numbers.

[0067] In some embodiments, the above-mentioned filler structure 25 can adopt the structure as shown in Figure 3 . Referring to Figure 3 , the filler structure 25 includes a hopper 251, a transfer funnel 252, and a quantitative delivery component 253. The hopper 251 is arranged on the first sliding seat 22. The transfer funnel 252 is fixedly arranged on the first sliding seat 22, and the discharge end thereof is in communication with the top end of the filler pipe 24. The quantitative delivery component 253 is connected to the hopper 251 and the transfer funnel 252, respectively, and can quantitatively deliver the metal powder in the hopper 251 to the transfer funnel 252.

[0068] The hopper 251 can hold the metal powder. The quantitative delivery component 253 can ensure that the metal powder is delivered to the transfer funnel 252, thereby realizing the filling of the metal powder. The quantitative delivery component 253 can ensure the quantitative filling of the metal powder, thereby adapting to different specifications of the cylindrical shell 40. The transfer funnel 252 is in communication with the filler pipe 24, which can ensure that the quantitative metal powder enters the filler pipe 24.

[0069] In some embodiments, the above-mentioned quantitative delivery component 253 can adopt the structure as shown in Figure 3 . Referring to Figure 3The quantitative delivery component 253 comprises a delivery cylinder 2531, a rotating shaft 2532, a helical blade 2533, and a driver 2534. One end of the delivery cylinder 2531 is in communication with the bottom end of the hopper 251, and the other end is in communication with the transfer hopper 252. The rotating shaft 2532 is coaxially arranged with the delivery cylinder 2531 and rotationally connected with the delivery cylinder 2531 and the hopper 251. The helical blade 2533 is located in the delivery cylinder 2531 and helically wound on the rotating shaft 2532. The driver 2534 is fixedly arranged on the hopper 251 and power-connected with the rotating shaft 2532.

[0070] The delivery cylinder 2531 can connect the hopper 251 and the transfer hopper 252. The delivery cylinder 2531 can be arranged in a horizontal direction, or the height of the outlet section is higher than that of the inlet end, so as to avoid overflow of the metal powder. The rotating shaft 2532 can drive the helical blade 2533 to rotate under the driving of the driver 2534. The helical blade 2533 can also prevent the metal powder in the delivery cylinder 2531 from being guided into the transfer hopper 252, thereby further improving the quantitative control effect.

[0071] The driver 2534 can be a servo motor.

[0072] In some embodiments, the hole sealing assembly 30 can adopt the structure as shown in Figure 2 and Figure 4 . Referring to Figure 2 and Figure 4 , the hole sealing assembly 30 comprises two second guide rods 31, a second sliding seat 32, a second telescopic structure 33, a filling pipe 34, a storage hopper 35251, and a pressurizing structure 36. The two second guide rods 31 are arranged on both sides of the linear conveying part and are arranged in a vertical direction. The second sliding seat 32 is located above the linear conveying part and is slidingly connected with each second guide rod 31. The second telescopic structure 33 can drive the second sliding seat 32 to move up and down. The filling pipe 34 is arranged in a vertical direction and has a top end connected with the second sliding seat 32. The storage hopper 35251 is fixedly arranged on the second sliding seat 32 and has a storage cavity with an open top end. The storage hopper 35251 is provided with a heating structure and can store molten wax. The pressurizing structure 36 can pressurize the inside of the storage cavity, so that the molten wax is extruded from the filling pipe 34.

[0073] The hole sealing assembly 30 works after the conveying belt 11 stops, and can work synchronously with the filling assembly 20, thereby improving the production efficiency.

[0074] The second telescopic structure 33 can drive the second sliding seat 32 to move up and down. When the cylindrical shell 40 is stopped below the injection pipe 34, the second telescopic structure 33 drives the second sliding seat 32 to move downward, so that the injection pipe 34 extends into the opening of the cylindrical shell 40. Then, the pressure boosting structure 36 is used to extrude the storage bin 35251, so that the molten wax is extruded into the opening of the cylindrical shell 40, thereby realizing the sealing of the metal powder. After the molten wax solidifies, a fixed wax block is formed, which forms a tab, and the filling of the metal powder is completed.

[0075] The hole sealing assembly 30 can ensure the sealing of the filled metal powder, and can also form an automatic filling production line together with the filling assembly 20 and the conveying assembly 10, thereby improving the production efficiency.

[0076] In some embodiments, the pressure boosting structure 36 can adopt the structure as shown in Figure 2 and Figure 4 . Referring to Figure 2 and Figure 4 , the pressure boosting structure 36 includes a boom 361, a piston plate 362, and a third telescopic structure 363. The boom 361 is fixedly arranged on the second sliding seat 32 and has a connecting plate portion above the storage bin 35251. The piston plate 362 is arranged in the storage cavity and is in sliding connection with the storage cavity in the vertical direction. The third telescopic structure 363 is fixedly arranged on the connecting plate portion and is connected with the piston plate 362.

[0077] The boom 361 can ensure the installation of the third telescopic structure 363. After the third telescopic structure 363 drives the piston plate 362 to move downward, the storage cavity can be pressurized, and the molten wax can be extruded. The third telescopic structure 363 can be a servo cylinder, thereby ensuring the control of the injection amount.

[0078] In some embodiments, the injection pipe 34 can adopt the structure as shown in Figure 4 . Referring to Figure 4 , the injection pipe 34 is provided with a blocking structure 37 capable of blocking the molten wax. The blocking structure 37 can be opened during the pressurization of the third structure, so that the molten wax enters the cylindrical shell 40. After the pressurization is released, the bottom end of the injection pipe 34 is blocked.

[0079] Specifically, referring to Figure 5 , the blocking structure 37 can include an upper fixed ring 371, a lower fixed ring 372, a blocking ball 373, and a spring 374. The upper fixed ring 371 and the lower fixed ring 372 are arranged in the interior of the injection pipe 34 and are spaced apart. The blocking ball 373 is located between the upper fixed ring 371 and the lower fixed ring 372 and continuously abuts and seals the center hole of the upper fixed ring 371 under the pushing of the spring 374, thereby preventing the molten wax from overflowing.
