[0053] In order to make the technical purpose, technical scheme and technical effect of the utility model clearer and to facilitate those skilled in the art to understand and implement the utility model, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0054] like Figure 1-Figure 2 As shown, the utility model proposes a multi-layer feeding device, including a plurality of quantitative structures 3 corresponding to different or non-identical multi-tube metal powders and used to quantify the multi-tube metal powders respectively, a blanking structure 1, a feeding structure 4 used to receive the metal powder discharged from the blanking structure 1 and feed the metal powder into a mold cavity 424, and a hopper driving mechanism connected to the blanking structure 1 and used to drive the blanking structure 1 to move to the bottom of any quantitative structure 3 so that the blanking structure 1 receives the metal powder discharged by the quantitative structure 3 after quantitative weighing and drives the blanking structure 1 to move to the top of the feeding structure 4 so that the blanking structure 1 feeds the feeding structure 4.

[0055] The above technical solution is a basic solution. Through the cooperation of the blanking structure and the hopper driving mechanism, the blanking structure can receive different or non-complete multi-tube metal powders in batches, and introduce the different or non-complete multi-tube metal powders into the mold cavity through the distribution structure one by one, thereby realizing the automation of multi-layer distribution of metal powders.

[0056] Further, in this embodiment, the hopper driving mechanism includes a driving motor 501, a driving wheel 502, a driven wheel 503, a belt 504 and a support frame 507;

[0057] The driving motor 501 includes a first cylinder body 505 relatively fixedly mounted on a support frame 507 and a driving shaft 506 rotatably mounted on the first cylinder body 505; a driving wheel 502 is relatively fixedly sleeved on the driving shaft 506, and a driven wheel 503 is rotatably mounted on the support frame 507; a belt 504 is connected between the driving wheel 502 and the driven wheel 503;

[0058] The blanking structure 1 is relatively fixedly mounted on the belt 504 .

[0059] Here, the driving shaft 506 rotates to drive the blanking structure 1 to move with the belt 504, thereby achieving the technical effect that the driving blanking structure 1 can move to the bottom of any quantitative structure 3 to receive the metal powder that is quantitatively weighed and discharged by the quantitative structure 3 and is used to drive the blanking structure 1 to move to the top of the distribution structure 4 to discharge the material to the distribution structure 4. Preferably, in this embodiment, the driving shaft 506 of the driving motor 501 can rotate forward and reverse relative to the first cylinder 505.

[0060] In other embodiments, the hopper driving mechanism may adopt a ball screw structure, or other linear reciprocating motion structures.

[0061] Furthermore, in this embodiment, a plurality of quantitative structures 3 are respectively arranged in parallel.

[0062] Specifically, in this embodiment, Figure 3-Figure 8 As shown, the quantitative structure 3 includes a base 301, a base plate 302 located above the base 301, a lifting mechanism connected to the base 301 and the base plate 302 respectively and used to drive the base plate 302 to perform lifting movement relative to the base 301, a linear guide 304 directly or indirectly mounted on the base plate 302, a first slider 305 slidably mounted on the linear guide 304, and a metal powder guide cylinder 303 directly or indirectly fixedly mounted on the first slider 305;

[0063] The base 301 is provided with a first through hole 325, and the substrate 302 is provided with a stepped hole 308 coaxially arranged with the first through hole 325;

[0064] The quantitative structure 3 further includes a connecting cylinder 326 respectively inserted into the first through hole 325 and the step hole 308 and clamped on the step hole 308, and a first linear driving mechanism connected to the first slider 305 and used to drive the first slider 305 to slide on the linear guide 304 so that the metal powder guide cylinder 303 and the connecting cylinder 326 are connected;

[0065] The quantitative structure 3 further includes a gate switch mechanism 2 mounted on the base 301 and used for opening or closing the bottom opening of the first through hole 325 .

[0066] The above technical scheme is the basic scheme of the quantitative structure 3. The technical principle of the quantitative structure 3 for the quantitative measurement of metal powder is as follows: 1) the gate switch mechanism 2 is used to close the bottom opening of the first through hole 325; 2) the first linear drive mechanism is used to drive the first slider 305 to slide on the linear guide 304 so that the metal powder guide cylinder 303 and the connecting cylinder 326 are docked; 3) the lifting mechanism is used to adjust the distance of the substrate 302 relative to the base 301, thereby adjusting the height from the top opening of the connecting cylinder 326 to the bottom opening of the first through hole 325; 4) the metal powder guide cylinder 303 is used to fill the space between the top opening of the connecting cylinder 326 and the bottom opening of the first through hole 325 with metal powder. In the above technical principle, by adjusting the height from the top opening of the connecting cylinder 326 to the bottom opening of the first through hole 325, the scale of the quantitative structure 3 for the quantitative measurement of metal powder can be adjusted. In this embodiment, the base 301 is relatively fixedly mounted on the support frame 507. In other embodiments, the gate switch mechanism 2 is relatively fixedly mounted on the support frame 507.

[0067] Further, in this embodiment, the quantitative structure 3 includes a first mounting member 306 and a second mounting member 307 respectively fixedly mounted on the substrate 302, and the first mounting member 306 and the second mounting member 307 are arranged opposite to each other; and both ends of the linear guide 304 are respectively fixedly mounted on the first mounting member 306 and the second mounting member 307. In this way, the technical effect of indirectly mounting the linear guide 304 on the substrate 302 is achieved.

[0068] In this embodiment, the first mounting member 306 and the second mounting member 307 are both plates, which are respectively connected to the base plate 302 vertically. It can be understood that the shapes of the first mounting member 306 and the second mounting member 307 are not limited to plates, and can also be block-shaped, column-shaped, etc. At the same time, the linear guide 304 is a rod, and its two ends are respectively fixedly penetrated on the first mounting member 306 and the second mounting member 307; the first slider 305 is slidably sleeved on the linear guide 304.

[0069] Preferably, in other embodiments, the linear guide 304 may be a bar with a rectangular cross section and directly mounted on the substrate 302 .

[0070] Further, in this embodiment, the first linear drive mechanism is a first cylinder 313, and the first cylinder 313 includes a second cylinder body 312 and a first piston rod 311 telescopically mounted on the second cylinder body 312;

[0071] The second cylinder body 312 is directly or indirectly fixedly mounted on the base plate 302 , and the first piston rod 311 is directly or indirectly fixedly connected to the first sliding block 305 .

[0072] Driven by the first cylinder 313, the metal powder guide cylinder 303 can be connected with the connecting cylinder 326 along with the first slider 305, or can be deviated from the connecting cylinder 326 along with the first slider 305. In another embodiment, the first linear drive mechanism can also be a ball screw mechanism to drive the first slider 305 to slide.

[0073] Preferably, in this embodiment, the second cylinder 312 is fixedly mounted on the second mounting member 307, and the first piston rod 311 telescopically passes through the second mounting member 307. In this way, the second cylinder 312 is indirectly fixedly mounted on the base plate 302 by the second mounting member 307, thereby reducing the size of the base plate 302.

[0074] Further, in this embodiment, a first fixing hole 323 is provided on the base 301, and the lifting mechanism includes a guide rod 317, which is fixedly inserted into the first fixing hole 323, and the base plate 302 is slidably mounted on the guide rod 317; the lifting mechanism also includes a motor 316, and the motor 316 includes a third cylinder 318 and a threaded output shaft 319 installed on the third cylinder 318; the third cylinder 318 is directly or indirectly fixedly installed on the base plate 302, and a threaded hole (not shown in the figure) is provided on the base 301, and the threaded output shaft 319 is threadedly connected in the threaded hole. Here, the guide rod 317, the motor 316, the base 301 and the base plate 302 are equivalent to a ball screw structure, and the base plate 302 is lifted and lowered relative to the base 301 by the threaded output shaft 319 rotating forward and reverse in the threaded hole of the base 301.

[0075] Furthermore, the lifting mechanism includes a cushion block 320 fixedly mounted on the base plate 302, and the third cylinder 318 is fixedly mounted on the cushion block 320; a second through hole 324 is provided on the cushion block 320, and the cushion block 320 is slidably mounted on the guide rod 317 through the second through hole 324. The third cylinder 318 is indirectly fixedly mounted on the base plate 302 through the cushion block 320. In this embodiment, the base plate 302 is relatively thin, and the third cylinder 318 is firmly fixed through the cushion block 320.

[0076] Furthermore, in this embodiment, there are two guide rods 317, and the two guide rods 317 are respectively connected to the base 301, the base plate 302, and the cushion block 320 in the same manner. Through two guide rods 317, or more guide rods 317, the lifting movement of the base plate 302 relative to the base 301 is more stable.

[0077] Further, a first mounting plate 321 is formed protruding from the first slider 305, and the quantitative structure 3 further includes a second mounting plate 322 fixedly mounted on the first piston rod 311, and the second mounting plate 322 is fixedly connected to the first mounting plate 321. Through the second mounting plate 322 and the first mounting plate 321, the first cylinder 313 is more likely to drive the first slider 305. Preferably, the second mounting plate 322 and the first mounting plate 321 are connected by screws.

[0078] Furthermore, in this embodiment, the quantitative structure 3 further includes a second cylinder 315, which includes a fourth cylinder body 310 directly or indirectly fixedly mounted on the first slider 305 and a second piston rod 309 telescopically mounted on the fourth cylinder body 310; the quantitative structure 3 further includes a ramming hammer 314 fixedly mounted on the second piston rod 309. In this embodiment, the first piston rod 311 has two states of extension and retraction. When the first piston rod 311 is in the retracted state, the metal powder guide cylinder 303 is docked with the connecting cylinder 326, so that the edge and the metal powder are discharged into the inside of the connecting cylinder 326 through the metal powder guide cylinder 303; when the first piston rod 311 is in the extended state, the ramming hammer 314 is coaxially arranged with the connecting cylinder 326, and then the ramming hammer 314 is driven by the second cylinder 315 to extend into the connecting cylinder 326 to flatten the metal powder inside the connecting cylinder 326.

[0079] Furthermore, the connecting tube 326 includes a tube body 327 and a ring portion 328 formed outwardly at the top of the tube body 327 , and the connecting tube 326 can be clamped on the step hole 308 through the ring portion 328 .

[0080] like Fig. 9 As shown, the material discharge structure 1 includes a hopper 101, and a discharge port 116 is provided at the bottom of the hopper 101;

[0081] The blanking structure 1 also includes a first rotating shaft 112 rotatably mounted directly or indirectly on the hopper 101, a gate 110 sleeved on the first rotating shaft 112 and used to rotate with the first rotating shaft 112 to open or close the discharge port 116, a gear 111 fixedly sleeved on the first rotating shaft 112, a rack 106 meshing with the gear 111, and a rack drive mechanism connected to the rack 106 and used to drive the rack 106 to move.

[0082] The above technical solution is the basic solution. Fig. 9 The state where the discharge port 116 is opened is shown. Fig. 9 In the embodiment, when the rack 106 moves to the left, the rack 106 drives the gear 111 to rotate, and the first rotating shaft 112 and the gate 110 rotate accordingly, so that the gate 110 closes the discharge port 116. Afterwards, if the rack 106 moves to the right, the rack 106 drives the gear 111 to rotate in the opposite direction, and the first rotating shaft 112 and the gate 110 rotate in the opposite direction, so that the gate 110 reopens the discharge port 116. In the process of the gate 110 opening or closing the discharge port 116, the gate 110 is in a rotating state, so that the metal powder discharged from the hopper 101 will not remain on the gate 110, thereby reducing the deviation of the metal powder that needs to be quantitatively discharged during the discharge. It can be understood that the gate 110 should be kept as clean and dry as possible.

[0083] Further, Figure 10-11The gate 110 includes a gate body 109 and a first shaft cylinder 108 fixedly connected to the gate body 109; the first shaft cylinder 108 has a second fixing hole 113 in the axial direction, and a first male stop 114 is formed on the inner wall of the second fixing hole 113;

[0084] The first rotating shaft 112 is provided with a female stopper 115 . The first rotating shaft 112 is inserted into the second fixing hole 113 , and the female stopper 115 and the first male stopper 114 are matched with each other.

[0085] Here, the female stop 115 and the first male stop 114 cooperate with each other, so that the first rotating shaft 112 and the gate 110 can rotate synchronously.

[0086] Furthermore, the gear 111 is axially provided with a third fixing hole, and a second male stop 117 is formed on the inner wall of the third fixing hole; the gear 111 is sleeved on the first rotating shaft 112 through the third fixing hole, and the second male stop 117 cooperates with the female stop 115.

[0087] Here, the second male stop 117 cooperates with the female stop 115 to achieve synchronous rotation of the gear 111 and the first rotating shaft 112 .

[0088] Furthermore, in this embodiment, if Fig. 9 As shown, the hopper 101 is provided with a second shaft cylinder 107; the first shaft 112 is rotatably inserted into the second shaft cylinder 107, thereby achieving the effect of being rotatably and indirectly installed on the hopper 101. In other embodiments, the first shaft 112 can be directly and rotatably inserted into the second shaft cylinder 107.

[0089] Furthermore, in this embodiment, Fig. 9 There are two second shaft cylinders 107 , and the two second shaft cylinders 107 are coaxially arranged opposite to each other; the first shaft cylinder 108 is located between the two second shaft cylinders 107 , so that the first rotating shaft 112 is respectively passed through the two second shaft cylinders 107 and the second fixing hole 113 .

[0090] Further, in this embodiment, the rack drive mechanism is a third cylinder 104, and the third cylinder 104 includes a fifth cylinder body 103 and a third piston rod 102 telescopically mounted on the fifth cylinder body 103;

[0091] The third piston rod 102 is fixedly connected to the rack 106 .

[0092] Here, if Fig. 9 As shown, the left and right movement of the rack 106 is achieved through the third cylinder 104. It can be understood that in other embodiments, the rack drive mechanism can adopt a ball screw structure, or other structures that can achieve linear reciprocating motion.

[0093] Furthermore, the material dropping structure 1 also includes a connection structure fixedly connected to the fifth cylinder 103 and the hopper 101 respectively.

[0094] The fifth cylinder 103 and the hopper 101 are relatively fixed by the connection structure. It can be understood that in other embodiments, the structure of the hopper 101 can be further expanded, and the fifth cylinder 103 can be directly fixedly mounted on the hopper 101.

[0095] Furthermore, the connection structure includes an L-shaped positioning frame 105, and the L-shaped positioning frame 105 includes a first positioning plate and a second positioning plate vertically connected to each other, the first positioning plate is fixedly mounted on the hopper 101, and the fifth cylinder 103 is fixedly mounted on the second positioning plate.

[0096] Further, in this embodiment, the blanking structure 1 is a small precision structure, and the fifth cylinder 103 is fixed on the second positioning plate by a nut clamping method. In this embodiment, the hopper 101 is directly or indirectly mounted on the belt 504 .

[0097] like Figure 12-Figure 15 As shown, the utility model proposes a gate switch mechanism 2, comprising a base 201 fixedly mounted on the bottom of a base 301, and a first gate 202 communicating with a first through hole 325 is formed on the base 201;

[0098] The gate switch mechanism 2 also includes a second rotating shaft 218 rotatably mounted on the base 201, a first switch member 203 relatively fixedly mounted on the second rotating shaft 218 and used to rotate with the second rotating shaft 218 to open or close the first gate 202, a first connecting rod 204 relatively fixedly mounted on the second rotating shaft 218, a second connecting rod 205 directly or indirectly rotatably mounted on the base 201, a third connecting rod 206 whose two ends are respectively hinged to the first connecting rod 204 and the second connecting rod 205, a fourth connecting rod 207 connected to the middle part of the third connecting rod 206, and a connecting rod driving mechanism connected to the fourth connecting rod 207 and used to drive the fourth connecting rod 207 to move.
