Description

Technical Field

[0001] The invention relates to the technical field of polysilicon crushing and processing, and in particular to a feeding device for a polycrystalline jaw crusher. Background Art

[0002] The main purpose of polysilicon crushing is to break it into particles of appropriate size for subsequent processing and production. Polysilicon may form some defects during the crystallization process, which will cause the efficiency of solar cells to decrease. Therefore, breaking polysilicon into particles of appropriate size can make it easier to purify and grow crystals, thereby improving the photoelectric conversion efficiency of solar cells.

[0003] The crushing method is generally completed by a jaw crusher; but since the jaw crusher is set at a higher position above the crushing platform, the polysilicon material needs to be transferred to the top of the platform and then fed manually when the crusher is fed. The polysilicon material is packed in a bag, and the operator directly pours the polysilicon material in the bag into the feed port of the jaw crusher when feeding, and then puts the empty bag aside; this feeding method has the following problems: First, there is a risk of the bag falling into the jaw crusher during the feeding process; second, due to the high feeding position, operators need to be arranged at the position where the polysilicon material is fed to the crushing platform and below the crushing platform; the operation process is cumbersome, which affects the feeding speed, and it is difficult to meet the processing capacity of the jaw crusher manually; third, some powder is easily dispersed in the surrounding environment during the operator's dumping of the bag, affecting the surrounding working environment, and the operator is prone to inhaling silicon powder. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a feeding device for a polycrystalline jaw crusher, through which the silicon material in the silicon bag is put into the feeding box, and the industrial robot completes the high-position feeding, avoiding manual feeding at the same time as collecting the packaging bags, and also avoiding the dispersion of dust during manual dumping, which affects the working environment around the operators, improves the high and low position feeding speed, and adapts to the automated production process.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0026] like Figure 1 , 2 As shown, a feeding device for a polycrystalline jaw crusher mainly relies on a conveying roller 1 for cyclic feeding. The conveying roller 1 is a U-shaped conveying path; three groups of conveying chains are arranged on the inner side of the conveying roller 1; the three groups of conveying chains of the conveying roller 1 are conveyed in reverse direction by a lifting roller group 20; the lifting roller group 20 includes a roller seat 21, a lifting roller and a lifting cylinder 22; the lower part of the roller seat 21 is fixed to the telescopic end of the lifting cylinder 22, and a lifting roller group 20 is arranged on the inner side of the roller seat 21. An industrial robot 24 for clamping the feeding box 2 is arranged on the inner side of the conveying roller 1, and the industrial robot 24 has a clamping claw for grabbing the feeding box. A support backrest 3 is fixed to the inner middle of the conveyor roller 1; a group of upper and lower bins 4 are fixed on the support backrest 3; the bottom of the lower bin 4 corresponds to the conveying path of the conveyor roller 1; the industrial robot 24 clamps the upper bin 2 in a full state from one end of the conveyor roller 1, and puts down the upper bin 2 in an empty box state from the other end of the conveyor roller 1; the upper bin 2 in an empty box state moves along the conveyor roller 1 to the full state end; the upper bin 2 in an empty box state stops moving when it reaches the lower bin 4. A photoelectric switch is set at the lower bin 4, and the conveyor roller 1 stops moving and conveying after the upper bin senses the upper bin 2 below.

[0027] like Figure 3-5As shown, the front and bottom of the lower material bin 4 are open structures; the side wall of the lower material bin 4 corresponding to the front open position is fixed with a feeding side plate 5; the top of the feeding side plate 5 is movably provided with an upper cover 18; slots are provided on both sides of the upper cover 18 to engage with the side plates; a front baffle 19 is vertically fixed to the front of the upper cover 18; a bag feeding gap is reserved below the front baffle 19; the front baffle 19 is made of transparent material, and the transparent material can be acrylic plate or glass, which is convenient for the operator to observe whether the bottom of the packaging bag is inserted under the bag clamping plate 7 when feeding. A bag turning roller group 6 is rotatably provided between the feeding side plates 5, and the bag turning roller group 6 is driven to turn over by the bag turning motor 12; a bag clamping cylinder 8 is fixed to the bottom of the bag turning roller group 6; a bag clamping plate 7 is provided on the end surface of the bag turning roller group 6; the telescopic end of the bag clamping cylinder 8 movably passes through the bag turning roller group 6 and is connected to the bag clamping plate 7, and the bag clamping cylinder 8 is controlled by an electromagnetic valve, and the electromagnetic valve can be connected to a switch button, and the operator manually controls the lifting and lowering of the bag clamping plate 7. When the upper material box 2 moves along the conveyor roller 1, it passes the bottom of the lower material bin 4. In order to facilitate automatic bag discharge, a bag discharge channel 6.2 is provided on the roller frame 6.1 of the bag-turning roller group 6; a rotating shaft 9 is movably provided at the bottom of the roller frame 6.1 of the bag-turning roller group 6; a connecting rod 10 that rotates with the rotating shaft 9 is fixed on the rotating shaft 9; one end of the rotating shaft 9 is connected to the driving end of the bag discharge motor 13; a vacuum suction cup 11 is fixed at the end of the connecting rod 10; when the vacuum suction cup 11 rotates to a horizontal position, the vacuum suction cup 11 corresponds to the position of the bag discharge channel 6.2, and the vacuum suction cup 11 is controlled to be on and off by a solenoid valve.

[0028] like Figure 3 , 5 As shown, in order to avoid dust during the unloading process, a fixed baffle 14 is provided at the front side of the bottom of the lower bin 4; sealing plates 15 are movably provided on both sides of the bottom of the lower bin 4; the side wall of the lower bin 4 is hinged to the bottom of the closed cylinder 16; the telescopic end of the closed cylinder 16 is hinged to the sealing plate 15, and the sealing plate 15 is driven to close or open by the closed cylinder 16; a dust collecting back cover 17 is fixed to the back of the lower bin 4; the dust collecting back cover 17 is connected to the smoke and dust main pipe through a pipeline, and the smoke and dust main pipe has negative pressure. The opening of the upper bin 2 is surrounded by fixed baffles 14, sealing plates 15, and dust collecting back cover 17; when the upper bin 2 moves below the lower bin 4, the gap between the lower bin 4 and the upper bin 2 will be closed. The dust generated in the upper bin 2 enters the dust collecting back cover 17 through negative pressure. Furthermore, a bag receiving groove 23 is placed under the feeding side plate 5; when the connecting rod 10 is flipped to a vertical state, the vacuum suction cup 11 pulls the packaging bag out of the bag outlet channel 6.2; the vacuum suction cup 11 is disconnected by the solenoid valve, and the packaging bag falls into the bag receiving groove 23. Since the bag turning roller group 6 needs to rotate, the pipeline of the vacuum suction cup 11 uses a spring pipeline and a sufficient length is reserved. If the fixing method is not separately introduced above, it is welded or threaded by common technical means of technical personnel in the industry, and the bag turning motor uses a stepping motor.

[0029] Here’s how it works:

[0030] The operator sets the position of the front baffle 19 for handling the opened silicon material package; the empty loading box 2 moves along the conveyor roller 1 to the position of the lower material bin 4 and then stops, and the sealing plate 15 is closed by the closing cylinder 16; the operator places the silicon material package horizontally on the bag turning roller group 6, and when placing it, the bottom edge of the packaging bag is inserted under the bag clamping plate 7, and then the operator controls the bag clamping cylinder 8 to descend, and the bag clamping plate 7 fixes and presses the bottom edge of the packaging bag; the bag discharge motor 13 controls the connecting rod 10 to rotate to a horizontal state, and the vacuum suction cup 11 adsorbs the side of the lying packaging bag; the bag turning motor 12 is started to start flipping. The bag-turning roller group 6 turns over to the side of the lower silo 4 to pour the silicon material in the packaging bag into the loading box 2. After the dumping operation is completed, the various mechanisms of the equipment are reset in sequence; during the resetting process, the bag-discharging motor 13 changes from a horizontal state to a vertical state, so in this process, the packaging bag will be pulled out of the bag-discharging channel 6.2 by the vacuum suction cup 11. After the vacuum suction cup 11 is disconnected by the solenoid valve control, the packaging bag falls into the bag receiving groove 23.

[0031] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
