[0030] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] like Figure 1 As shown, an automatic crucible feeding device in one embodiment of this application includes a discharging mechanism 100 and a dispensing mechanism 200, wherein:

[0032] The material feeding mechanism 100 is located above the dispensing mechanism 200 and includes a hanging frame 120 for suspending the material bag 101 and a material feeding hopper 110. The material feeding hopper 110 is located on one side of the top of the dispensing mechanism 200.

[0033] The dispensing mechanism 200 includes a mounting plate 210, a dispensing funnel 220, and several material cylinders 310. The material cylinders 310 are mounted to the bottom of the mounting plate 210 and are flush with the surface of the mounting plate 210. The distribution of the material cylinders 310 is consistent with the material level of the crucible tray. A switching mechanism 330 is provided on the material cylinder 310 to close or open the bottom opening of the material cylinder 310. The dispensing funnel 220 can slide back and forth on the mounting plate 210 under the drive of the driving mechanism 230 to add material to the material cylinder 310.

[0034] The dispensing mechanism 200 is installed in a dust cover, which is equipped with a dust extraction fan. The dust extraction fan can remove the smoke and dust during the material feeding process, prevent dust explosions, and improve safety.

[0035] In this embodiment, the crucible tray is placed on the bottom of the mounting plate 210, and the crucibles and the barrels 310 are aligned one-to-one. A forklift or a special support frame can be used to support the crucible tray during placement.

[0036] After the material in the material bag 101 is added to the discharge hopper 110, it falls from the discharge hopper 110 into the bottom dispensing funnel 220. The dispensing funnel 220 moves to the top of each material cylinder 310 under the drive of the drive mechanism 230, dropping the material into the material cylinder 310, and moves back and forth to ensure that the material in each material cylinder 310 is filled. The volume of the material cylinder 310 can be set to the volume of the required material.

[0037] After the material in the barrel 310 is filled, the switch mechanism 330 is opened, allowing the material to fall into the crucible below, thus completing the dispensing.

[0038] In this embodiment, the mounting plate 210 is a smooth iron plate, and the bottom outlet of the dispensing funnel 220 abuts against the cover iron plate. It will not leak out where there is no material cylinder 310, but can only leak out at the material cylinder 310.

[0039] In one embodiment of this application, a mounting plate 210 is fixed to a mounting frame 10, and a drive mechanism 230 is fixed to the mounting frame 10. The drive mechanism 230 includes a servo motor and a drive chain. A dispensing funnel 220 is slidably connected to the mounting frame 10 and connected to the drive chain. The servo motor drives the drive chain to move back and forth. Slide rails are provided on both sides of the mounting frame 10. The two ends of the dispensing funnel 220 are slidably connected to the cover slide rails. Sprockets are provided at the front and rear ends of the slide rails, respectively. The two ends of the chain are wound around the sprockets and connected to the dispensing funnel 220. The servo motor drives one of the sprockets to rotate, thereby realizing the back and forth movement of the dispensing funnel 220.

[0040] In use, by controlling the dispensing funnel 220 to move back and forth a few times, all the material cylinders 310 can be filled and leveled.

[0041] In one embodiment of this application, the width of the dispensing funnel 220 is the same as the width of the mounting plate 210, and an auger is provided in the dispensing funnel 220. The auger can agitate the material in the dispensing funnel 220 to prevent blockage during the dispensing process; moreover, during the forward and reverse rotation of the auger, the material can be evenly distributed to ensure that each material cylinder 310 is filled.

[0042] In one embodiment of this application, an adjustment mechanism 300 is also included. The adjustment mechanism 300 includes an adjustment plate 320, the four corners of which are supported on the mounting frame 10 by servo electric cylinders 340. The material cylinder 310 is a telescopic cylinder, with its bottom connected to the adjustment plate 320 and its top fixed to the mounting plate 210. When the adjustment plate 320 rises, it compresses the telescopic cylinder to reduce its volume; when the adjustment plate 320 descends, it pulls the telescopic cylinder apart to increase its volume. This allows for adjustment to different volumes for crucibles of different specifications, improving the applicability of the device.

[0043] During adjustment, the four servo electric cylinders 340 move synchronously, adjusting the rising or falling distance as needed to improve accuracy.

[0044] In one embodiment of this application, the switching mechanism 330 is fixed to the adjusting plate 320. The switching mechanism 330 includes a switching plate 332 and a switching cylinder 331. The switching plate 332 is provided with a discharge port corresponding to the material cylinder 310. The switching cylinder 331 drives the switching plate 332 to move so that the discharge port coincides with or is offset from the material cylinder 310. During the filling process into the material cylinder 310, the switching cylinder 331 actuates to completely offset the discharge port on the switching plate 332 from the material cylinder 310, thereby sealing the bottom opening of the material cylinder 310. When the filling is completed and the material needs to be transferred to the crucible, the switching cylinder 331 actuates to completely coincide with the bottom opening of the material cylinder 310, thereby opening the material cylinder 310 and allowing the material to leak into the crucible.

[0045] In one embodiment of this application, the adjusting plate 320 includes an upper adjusting plate 321 and a lower adjusting plate 322. The upper adjusting plate 321 and the lower adjusting plate 322 are fixedly connected by a fixing block 323 and a gap is left. The material cylinder 310 includes an adjusting cylinder 311 and a loading cylinder 312 sleeved on the bottom of the adjusting cylinder 311. The loading cylinder 312 is fixed to the upper adjusting plate 321, and the top of the adjusting cylinder 311 is fixed to the mounting plate 210. The switch plate 332 is slidably connected between the upper adjusting plate 321 and the lower adjusting plate 322.

[0046] During the up-and-down movement of the adjusting plate 320, the bottom loading cylinder 312 can be moved upward, thereby compressing the space enclosed by the loading cylinder 312 and the adjusting cylinder 311, thus realizing the adjustment of the volume of the cylinder 310.

[0047] The fixing block 323 is located around the adjusting plate 320, which can fix the upper adjusting plate 321 and the lower adjusting plate 322, leaving a gap in the middle to facilitate the sliding of the switch plate 332. The lower adjusting plate 322 acts as a support to ensure that the switch plate 332 is in close contact with the upper adjusting plate 321, which helps to improve the sealing effect on the bottom opening of the material cylinder 310 and prevents material leakage caused by the switch plate 332 drooping naturally. Moreover, this design can also guide the movement of the switch plate 332 to ensure accurate closing and opening.

[0048] The switching cylinder 331 is fixed to the lower adjusting plate 322, and the end of the switching plate 332 extends out of the gap and is fixedly connected to the piston rod of the switching cylinder 331.

[0049] In one embodiment of this application, the lower adjusting plate 322 is provided with guide cylinders 324 corresponding one-to-one with the material cylinders 310. The guide cylinders 324 are used to connect with the crucibles. When the crucible tray reaches the bottom of the dispensing mechanism 200, it is easy to observe and ensure that the crucible is accurately aligned with the guide cylinders 324, so that the guide cylinders 324 enter the crucible, ensuring the accuracy of material dispensing and avoiding misalignment and leakage.

[0050] In one embodiment of this application, a plurality of vibration motors 350 are provided on the adjusting plate 320; during the feeding process, the vibration motors 350 are activated to thoroughly shake the material into the crucible, avoiding blockage that could affect the feeding effect. To prevent the vibration motors 350 from affecting the servo cylinder 340, a rubber pad is provided between the servo cylinder 340 and the adjusting plate 320.

[0051] A pointer 325 is provided on one side of the adjusting plate 320, and a scale matching the pointer 325 is provided on the mounting bracket 10. The rising and falling of the adjusting plate 320 causes the pointer 325 to move up and down, and the position pointed to by the pointer 325 represents the current volume of the material cylinder 310.

[0052] In one embodiment of this application, a pressing device is provided on both sides of the hanger 120. The pressing device includes a pressing plate 132 and a pressing cylinder 131. The bottom of the pressing plate 132 is hinged to the bottom of the hanger 120, and the pressing cylinder 131 is connected to the middle of the pressing plate 132 to push the pressing plate 132 to press the material bag 101. During the material bag 101 discharge process, it may become clogged due to the small bottom opening. The pressing cylinder 131 is used to press the material bag 101 to facilitate the material to leak into the dispensing funnel 220.

[0053] In one embodiment of this application, a baffle 111 is rotatably connected to the hopper 110, and a spring 113 is connected between the baffle 111 and the hopper 110. The spring 113 always applies elastic force to drive the baffle 111 to rotate and block the bottom discharge port of the hopper 110. A lever 112 is provided at the bottom of the baffle 111. The movement of the dispensing hopper can push the lever 112 to open the discharge port.

[0054] The dispensing funnel 220 is equipped with a level gauge. When there is no material, it will move to the discharge hopper 110. The dispensing funnel 220 can press against the push block 112 to push the baffle 111, causing the baffle 111 to rotate and expose the discharge port, so that the dispensing funnel 220 can be filled with material. After the material is filled, the dispensing funnel 220 is moved away, and the baffle 111 blocks the discharge port again under the action of the spring 113 to prevent the material from falling.

[0055] In one embodiment of this application, a brush is installed below the dispensing funnel 220. When in motion, the brush can sweep excess material on the table into the waste bins at the bottom of the front and rear ends.

[0056] According to one embodiment of this application, the beneficial effect of using this automatic crucible feeding device is that it can automatically fill all crucibles on the crucible tray at one time, and the filling accuracy is high. It can also fine-tune the filling amount according to different crucibles, which greatly improves the degree of automation.
