[0029] An embodiment of the present invention will now be described with reference to the accompanying drawings.

[0030] like Figure 1 As shown, this invention relates to an automatic silicon material feeding machine, including a real-time weighing device 2, a sealed conveying device 3, a separating and unloading device 4, and a trolley positioning device 5. The real-time weighing device 2 is located upstream of the sealed conveying device and is used to determine the feeding amount. A fixed amount of silicon material is pre-weighed to achieve quantitative filling. Its outlet is located at the starting position of the conveyor belt 32 of the sealed conveying device. The sealed conveying device 3 is inclined and the conveying direction is from bottom to top to realize the silicon material transmission process. It can meet the high inlet requirement of the refilling trolley 6 and reduce the space occupied, making the structure of this mechanism compact. The separating and unloading device 4 is provided at the end of the sealed conveying device to smoothly transport the silicon material from the sealed conveying device 3 to the refilling trolley. The trolley positioning device 5 is located below the end of the sealed conveying device and is used to position the refilling trolley 6. The refilling trolley 6 is positioned in an accurate position so that after the refilling trolley 6 is connected and positioned with the trolley positioning device 5, the outlet end of the separating and unloading device 4 matches the refilling trolley opening on the refilling trolley 6.

[0031] The sealing conveying device 3 includes a support frame 31, a conveyor belt 32, and a sealing groove 33. The upper surface of the support frame 31 is inclined to support the conveyor belt 32 and the sealing groove 33. The conveyor belt 32 is installed on the inclined surface of the support frame 31. The starting and ending ends of the conveyor belt 32 are both flat, and the conveying direction is from bottom to top. In order to ensure that the silicon material is not contaminated during the conveying process, a sealing groove 33 is provided above the conveyor belt 32 to cover the conveying process. The sealing groove 33 covers the conveyor belt 32 and is fixed on the support frame 31. The sealing groove 33 is open at the starting position of the conveyor belt 32 to facilitate the feeding of silicon material. Alternatively, a conveying inlet can be opened on the sealing groove 33 so that the silicon material can fall onto the conveyor belt 32 through the conveying inlet.

[0032] like Figure 3-4As shown, the real-time weighing device 2 includes a feeding frame 21 and a bucket-shaped feeding hopper 22. The feeding hopper 22 is fixedly mounted on the feeding frame 21. A pressure sensor is provided at the bottom of the feeding frame 21 for weighing. The bottom of the feeding hopper 22 is provided with a double-opening hopper door 23, which can be opened and closed. A symmetrical hopper door cylinder 24 is provided on the feeding frame 21. The piston end of the hopper door cylinder 24 is hinged to the double-opening hopper door 23. The hopper door cylinder 24 controls the hopper door 23 to close. The feeding hopper 22 is trough-shaped. After the silicon material falls into the feeding hopper 22, it is weighed by the pressure sensor. When the weight reaches the feeding amount, the feeding stops. The hopper door 23 is located at the starting position of the conveyor belt 32 or above the conveyor feed inlet. After the feeding stops, the hopper door cylinder 24 controls the hopper door 23 to open. The silicon material falls through the bottom outlet of the feeding hopper 22 onto the horizontal section of the conveyor belt 32 at the starting position of the conveyor belt 32.

[0033] like Figure 5 As shown, the separating and discharging device 4 includes a hopper 42, a swing bucket 43, and a swing cylinder 44. The separating and discharging mechanism is fixed to the end of the sealed conveying device 3 via a discharging frame 41. The hopper 42 is fixed on the discharging frame 41 and is located below the conveying outlet. The bottom of the hopper 42 is narrowed, corresponding to the swing bucket 43. The swing bucket 43 is trough-shaped with its end inclined downwards. The end of the swing bucket 43 has a smooth opening. After the silicon material is collected by the hopper 42, it falls into the swing bucket 43 and is discharged from the opening along the inclined groove of the swing bucket 43 into the re-feeding bucket. In order to facilitate the placement of two re-feeding buckets on a re-feeding trolley, the swing bucket 43 is set to a movable form. The swing bucket 43 is hinged to the discharging frame 41. A swing cylinder 44 is set on the discharging frame 41 on the rear side of the swing bucket 43. The piston end of the swing cylinder 44 is hinged to the back of the swing bucket 43. The swing cylinder 44 extends and retracts, causing the swing bucket 43 to swing left and right, thereby adjusting the angle at the opening to match the two re-feeding buckets placed side by side.

[0034] The base of the refilling bucket trolley 6 and the bucket seat on which the refilling bucket is placed are hinged. When feeding, the refilling bucket is placed at an angle. A push rod extends backward from the back of the bucket seat. The push rod is hinged to the back of the bucket seat. A positioning rod parallel to the bottom surface is provided on the base. The positioning rod extends backward and has a positioning groove at its end.

[0035] like Figure 2As shown, the trolley positioning device 5 includes a positioning frame 51, an upright cylinder 52, and a positioning device. The positioning frame 51 fixes the trolley positioning device 5 to the ground, maintaining a fixed relative position with the sealing conveying device 3. The upright cylinder 52 is hinged to the positioning frame 51, with its tail end hinged to the rear of the positioning frame 51. The front piston end can be connected to a push rod. During or after the loading process, when it is necessary to stand the refilling bucket upright to allow the silicon material to slide down, the piston of the upright cylinder 52 extends, pushing the push rod to make the refilling bucket stand upright. The positioning device is located at the front end of the positioning frame 51 and is used to determine the front-back direction of the refilling bucket trolley 6. The positioning device includes symmetrically arranged components. The guide wheel assembly 53 and guide mechanism 54 are configured such that the ends of the two guide wheel assemblies 53 are fixed to the front ends of the positioning frame 51, matching the width of the base of the refilling bucket trolley 6. Pulleys are installed in opposite directions on the two guide wheel assemblies 53. When the refilling bucket trolley 6 moves forward into the range of the trolley positioning device 5, the base slides forward with the assistance of the two guide wheel assemblies 53. The guide mechanism 54 consists of two columnar positioning structures fixed to the front of the positioning frame 51. A positioning protrusion is provided at the front of the guide mechanism 54, and the positioning protrusion and positioning groove are matched and can fit together. A position sensor or pressure sensor can be installed on the guide device to determine whether the positioning groove and positioning protrusion are engaged. In use, the refilling bucket trolley 6 moves forward into the range of the trolley positioning device 5. With the buffering assistance of the two guide wheel assemblies 53, the base moves the positioning rod towards the guide mechanism 54 until the positioning groove and positioning protrusion are engaged, determining the final position of the refilling bucket trolley 6 and aligning the outlet of the swing bucket 43 with the inlet of the refilling bucket. To ensure accurate positioning, the positioning rod and the guide mechanism 54 are both symmetrically arranged in pairs.

[0036] This solution uses a feeding and screening machine 1 to supply and screen silicon material. The outlet end of the feeding and screening machine 1 is located above the real-time load-bearing device, which can transport the silicon material to the feed hopper 22. The feeding and screening machine 1 can be a transmission device connected after the device with screening function. In addition, a blower mechanism 7 is also provided on the side of the sealed conveying device 3 for blowing air and dust removal to maintain a clean environment.
