Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of silicon material packing equipment, and specifically relates to a silicon material automatic packaging conveyor. BACKGROUND

[0002] The edge skin material is the edge skin waste material cut from the edge of the single crystal silicon round bar. The waste material belongs to good material in the photovoltaic single crystal production, has high silicon purity and is suitable for being matched with crystal pulling, and the edge skin material needs to be cleaned first to remove dust and stains thereon. The cleaned single crystal silicon waste material is more suitable for subsequent processing technology and can ensure the quality of subsequent products. The edge skin material after cleaning treatment is subjected to crushing treatment, and the crushed and bagged silicon material can be recycled.

[0003] The silicon material is packaged by the packaging bag sealing equipment. Since the shape of the silicon material is irregular, the weight of each bag of silicon material is controlled within a range, and the silicon material is considered unqualified when the weight exceeds the range. The unqualified material needs to be re-packed and re-filled. However, since the weighing equipment is located at the rear end of the packaging bag sealing equipment, the re-filled unqualified material needs to be returned to the front end of the equipment for re-packaging. This results in the flow operation of the operator at two positions, i.e., the unqualified material discharging area and the front end of the packaging bag sealing equipment, and the work process is complicated, which affects the operation efficiency.

[0021] like Figure 1 , 2 As shown, an automatic polysilicon packaging conveyor includes an automatic sealing machine 1, a sealing conveyor belt 2, a conveyor roller conveyor 3, a weighing conveyor belt 4, a return material mechanism 5, and a return material conveyor belt 6. The automatic sealing machine 1 is located above the inlet end of the sealing conveyor belt 2, and the automatic sealing machine 1 uses existing thermoplastic sealing equipment. A bag-tipping mechanism 7 is located at the outlet end of the sealing conveyor belt 2. The bag-tipping mechanism 7 includes a bag-blocking crossbar 7.1 and a bag-tipping ramp 7.2. The bag-blocking crossbar 7.1 is inclinedly positioned above the outlet end of the sealing conveyor belt 2. After the polysilicon bale moves to the position of the bag-blocking crossbar 7.1, the upper end of the polysilicon bale is blocked and tilted down by the bag-blocking crossbar 7.1. The bag-tipping ramp 7.2 is fixed opposite to the bag-blocking crossbar 7.1. The outlet end of the sealing conveyor belt 2 is connected to the conveyor roller conveyor 3. A weighing conveyor belt 4 is located between the conveyor roller conveyors 3. The weight of each polysilicon bale passing through the weighing conveyor belt is displayed. A hopper 8 for receiving silicon material bags is placed at the discharge end of the conveyor roller 3. Silicon material bags that meet the weight requirements will eventually enter the hopper 8 and be stacked neatly by the operators. Once the hopper 8 is full, a forklift will move the bags. Silicon material bags that do not meet the weight requirements will be weighed by the weighing conveyor belt 4 and will be pushed out of the conveyor roller 3 by the return mechanism 5 and enter the guide trough 5.4 of the return mechanism 5. The discharge port of the guide trough 5.4 is located above the return conveyor belt 6. The conveying direction of the return conveyor belt 6 is opposite to that of the conveyor roller 3. The discharge end of the return conveyor belt 6 is located below the feed end of the sealing conveyor belt 2.

[0022] As Figures 3-5 shown, the return mechanism 5 includes: the first push plate 5.1, the first push cylinder 5.2, the cylinder fixing frame 5.3, the guide slot 5.4, the second push plate 5.5, the second push cylinder 5.6; the cylinder fixing frame 5.3 is fixed on one side of the rack 3.1 of the conveying roller 3; the first push cylinder 5.2 is fixed below the cylinder fixing frame 5.3; the first push plate 5.1 is fixed at the telescopic end of the first push cylinder 5.2; the guide slot 5.4 is fixed at the opposite side of the first push plate 5.1; the guide slot 5.4 is embedded in the rack 3.1 of the conveying roller 3; the back of the guide slot 5.4 is fixed through the support 5.7; the second push cylinder 5.6 is fixed at the bottom of the guide slot 5.4; the second push plate 5.5 is fixed at the telescopic end of the second push cylinder 5.6; the second push plate 5.5 is located below the discharge port of the guide slot 5.4, and the bottom edge of the second push plate 5.5 is higher than the belt surface of the return conveying belt 6. Among them, the unqualified silicon material bag is removed by the first push cylinder 5.2, and there are two control methods, one is to put the weighing data into the processor, and if the weight is not in the preset range, the processor sends a command to control the electromagnetic valve to act, and the cylinder connected with the electromagnetic valve pushes out the unqualified silicon material bag. The other way is that the operator judges the weighing value and manually controls the electromagnetic valve to make the first push cylinder 5.2 act to push the silicon material bag that does not meet the weight into the guide slot 5.4.

[0023] As Figure 3 , 4 shown, further, considering that the silicon material bag cannot be accurately controlled to be located in the middle of the conveying belt after entering the guide slot 5.4, once the silicon material bag is located at the edge of the conveying belt, it is easy to appear material falling or the silicon material bag colliding with the rack 3.1, and finally being stuck in the gap position between the rack 3.1 and the return conveying belt 6, affecting the operation of the equipment. Therefore, the opposite side of the second push plate 5.5 is fixed with a baffle 5.9, and the baffle 5.9 and the second push plate 5.5 limit the entering silicon material bag in the middle of the return conveying belt 6; the rack 3.1 of the conveying roller 3 is provided with a fixed seat 5.8; the back of the baffle 5.9 is fixed with one end of the guide rod 9; the other end of the guide rod 9 is movably nested in the fixed seat 5.8; the fixed seat 5.8 is provided with a threaded hole, and the guide rod 9 is fixed through the adjusting screw, and the top of the adjusting screw is fixed with an adjusting disc, which can adjust the position of the baffle 5.9 according to the width of the return conveying belt 6. The above-mentioned is not introduced separately, and all uses the welding or screw fastening of the general technical means of the industry technical personnel.

[0024] The working principle is as follows:

[0025] The operator vertically places the loaded silicon material bag on the sealing conveying belt 2, the automatic sealing machine 1 is provided with guide wheels 1.1 on both sides of the sealing conveying belt 2, and the silicon material bag is moved along the sealing conveying belt 2 while completing the sealing operation; the silicon material bag completing the sealing operation is pushed to the horizontal conveying after reaching the bag reversing mechanism 7. The silicon material bag moves to the weighing conveying belt 4 position and is weighed, and the display screen of the weighing conveying belt 4 displays the weighing value after weighing; the silicon material bag continues to move forward to the material returning mechanism 5; if the weighing conveying belt 4 displays that the weight is unqualified, then the first pushing cylinder 5.2 is controlled to extend and push the silicon material bag out to the material guide slot 5.4; the silicon material bag entering the material guide slot 5.4 slides along the slope to the discharge port position of the material guide slot 5.4; at this time, the second pushing cylinder 5.6 acts to push the silicon material bag to the belt surface of the material returning conveying belt 6, the space between the second pushing plate 5.5 and the baffle corresponds to the middle part of the material returning conveying belt 6, so that the position of the silicon material bag is accurate, and the material returning conveying belt 6 returns the unqualified silicon material bag to the feeding end (i.e. below the feeding end of the sealing conveying belt 2), and the operator unpacks the returned silicon material bag and re-fills it.

[0026] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
