Description

Technical Field

[0001] This invention relates to the field of conveying and feeding technology, and in particular to a lithium iron phosphate powder conveying and feeding device. Background Technology

[0002] The ton bag delivery of lithium iron phosphate powder refers to the use of ton bags as packaging containers, and the unloading of large-capacity packages of lithium iron phosphate powder into designated locations in the production process using a specific device. This delivery method is suitable for large-volume, continuous production processes, improving work efficiency.

[0003] The existing method of conveying and feeding lithium iron phosphate powder usually involves using an automatic ton bag unpacking machine. However, the existing automatic ton bag unpacking machine usually only cuts the bottom of the ton bag when unpacking it, which is not efficient in discharging the powder inside the ton bag. There may be residual powder inside the ton bag. When the ton bag is removed and replaced later, dust leakage and residual powder inside the ton bag may occur, which may pollute the environment and endanger the health of workers.

[0015] Beneficial effects: 1. The lithium iron phosphate powder conveying and feeding device provided by the present invention uses a separation mechanism, a ton bag conveying mechanism and a silo door opening and closing mechanism to divide the working silo into three enclosed working areas: upper, middle and lower. This effectively avoids the problem of powder leakage in the working silo, which may occur when the existing unpacking machine opens the silo door to take out and replace the ton bag after unpacking the bag, thus polluting the environment and endangering the health of the workers.

[0016] 2. The lithium iron phosphate powder conveying and feeding device provided by the present invention uses a separation mechanism and a bag breaking mechanism in combination. In the lower working area, a conical seat and multiple bag cutting blades first perform preliminary cutting on the bottom of the ton bag. Then, the multiple bag cutting blades are controlled to open and perform secondary cutting on the side of the ton bag, which effectively increases the bag breaking effect and further improves the powder discharge effect after bag breaking.

[0017] 3. The lithium iron phosphate powder conveying and feeding device provided by this invention employs a combination of a separating mechanism, a ton bag conveying mechanism, a silo door opening and closing mechanism, a bag breaking mechanism, and a tapping mechanism. This allows the working silo to be divided into three enclosed working areas (upper, middle, and lower) without affecting the entry and exit of the wire rope and hook. The device can control the front and rear sealing plates to enclose the lower working area, and then perform preliminary cutting on the bottom of the ton bag in the lower working area. Subsequently, multiple bag-cutting blades are controlled to open and perform secondary cutting on the sides of the ton bag, effectively increasing the bag-opening effect and improving the discharge of powder after bag opening. The system effectively removes residual powder from the cut ton bags by lifting them to the central working area of ​​the working chamber and repeatedly tapping them. This further removes any remaining powder from the ton bags after cutting. The cut ton bags are then lifted out of the working chamber for repeated replacement and feeding. The entire process of unpacking, tapping, and removing the ton bags is carried out in a closed space, effectively avoiding the problems of powder leakage and residual powder in the working chamber that may occur when opening the chamber door to remove and replace ton bags using existing unpacking machines, which could pollute the environment and harm the health of workers.

[0033] See Figure 4 and Figures 7-9 The partition 54 includes a strip-shaped through hole 541 shared by the partition plate 51 and the working chamber 2. Both ends of the strip-shaped through hole 541 have right-opening C-shaped mounting grooves 542. Multiple compression springs connect C-shaped sliding plates 543 to each of the two C-shaped mounting grooves 542. The two C-shaped sliding plates 543 are slidably connected to their respective C-shaped mounting grooves 542, and the positions of the two C-shaped sliding plates 543 corresponding to the strip-shaped through hole 541 are wedge-shaped. Circular through holes 544 are provided at the upper end of the working chamber 2 and in the middle of the partition plate 51. Circular through holes 544 are shared by the two partition plates 53. Each of the multiple circular through holes 544 is equipped with a partition group. The device includes two rectangular mounting slots 545 on the inner wall of the circular through hole 544. Each rectangular mounting slot 545 is slidably connected to a rectangular sliding plate 546 by multiple compression springs. The lower end of the rectangular sliding plate 546 is wedge-shaped. The difference is that the multiple rectangular mounting slots 545 on the upper side and the middle are respectively connected to the corresponding C-shaped mounting slots 542. The multiple rectangular sliding plates 546 on the upper side and the middle have triangular notches at the positions corresponding to the strip through hole 541. The right end of the C-shaped sliding plate 543 is equipped with triangular extension plates 547 at the positions corresponding to the triangular notches of the multiple rectangular sliding plates 546 on the upper side and the middle. The multiple triangular extension plates 547 move and abut against the triangular notches of the corresponding rectangular sliding plates 546.

[0034] See Figure 2 , Figure 3 and Figure 9 The opening and closing part 55 includes a driven gear 551 fixedly sleeved on the front side shaft 52. Two shafts 552 are rotatably installed on the right side of the working chamber 2 behind the driven gear 551. The right ends of the two shafts 552 are respectively fixedly sleeved with a transmission gear 553 and an incomplete gear 554. The driven gear 551 meshes with the transmission gear 553, and the transmission gear 553 meshes with the incomplete gear 554 intermittently. The front shaft 552 and the rear shaft 52 are connected by a transmission belt. A reversible motor 555 is installed on the right side of the working chamber 2 through a motor base. The output shaft of the reversible motor 555 is fixedly connected to the rear shaft 552.

[0035] See Figure 7 and Figure 9 The door opening and closing mechanism 6 includes door opening and closing parts 61 symmetrically arranged on the front and back of the working chamber 2. The door opening and closing parts 61 include a sealing plate 611 hinged to the left end face of the working chamber 2. Two upper and lower arc rods 612 are hinged on the sealing plate 611. The ends of the two upper and lower arc rods 612 away from the sealing plate 611 are hinged to a round rod 613. A pneumatic push rod 614 is installed on the outer wall of the working chamber 2 through a mounting seat. The telescopic rod 984 of the pneumatic push rod 614 is fixedly connected to the round rod 613.

[0036] It should be noted that the electric hoist 43 is connected to a hook via a wire rope, and the two front and rear sealing plates 611 are initially in the open state. First, the electric hoist 43 is moved to the left side of the slide rail 41 by the electric slide table 42. Then, the hook is moved downwards to a suitable position by the electric hoist 43, and the ton bag to be transported is manually lifted by the hook. Then, the hook is moved upwards by the electric hoist 43 to the height corresponding to the feed inlet of the working chamber 2. Then, the electric hoist 43 is moved to the right side of the slide rail 41 by the electric slide table 42. During this process, the wire rope on the electric hoist 43 will first abut against the two front and rear U-shaped... The sliding plate 543 retracts into its corresponding I-shaped mounting groove 542, and then contacts the multiple rectangular sliding plates 546 on the upper and middle sides, causing them to retract into their corresponding rectangular mounting grooves 545. During this process, the triangular notches on the rectangular sliding plates 546 facilitate the smooth passage of the wire rope. When the hook moves the ton bag to the right into the working chamber 2, under the action of multiple compression springs, both the front and rear I-shaped sliding plates 543 will perform adaptive sliding compensation along the corresponding I-shaped mounting grooves 542 to return to their original positions, and the multiple rectangular sliding plates 546 on the upper and middle sides will perform adaptive sliding compensation along the corresponding rectangular mounting grooves 545 to contact the wire rope.

[0037] After the ton bag moves into the working compartment 2, the reversible motor 2555 controls the rear shaft 2 552 to drive the incomplete gear 554 to rotate. The teeth of the incomplete gear 554 are set to one-quarter of the circumference. The incomplete gear 554, the transmission gear 553, and the driven gear 551 drive the front shaft 1 52 to rotate 90 degrees clockwise and the front shaft 2 552 to rotate 90 degrees counterclockwise. Under the action of the transmission belt, the front and rear shafts 1 52 respectively drive the corresponding partition plates 2 53 to rotate downwards by 90 degrees. Then, the electric hoist 43 controls the hook to move the ton bag downwards to the appropriate position. Then, the reversible motor 2555 controls the rear shaft 2 552 to drive the incomplete gear 554 to rotate in the opposite direction. The teeth of the incomplete gear 554 are set to one-quarter of the circumference. The incomplete gear 554, the transmission gear 553, and the driven gear 551 drive the front and rear shafts 1 52 to rotate counterclockwise and clockwise respectively. The clock hand rotates 90 degrees to return to its original position. At this time, the opposite ends of the two partition plates 53 are tightly fitted together. The two rectangular sliding plates 546 on the lower side move together against the wire rope under the action of multiple compression springs. The hook and the ton bag are located on the lower side of the two partition plates 53. Then, the corresponding round rods 613 are controlled to move to the left by the two pneumatic push rods 614. The two round rods 613 drive the corresponding sealing plates 611 to rotate through the corresponding upper and lower arc rods 612 until the two sealing plates 611 are closed, thereby sealing the feed inlet of the working chamber 2. The partition mechanism 5, the ton bag conveying mechanism 4 and the chamber door opening and closing mechanism 6 work together to divide the working chamber 2 into three closed working areas: upper, middle and lower. This effectively avoids the problem of powder leakage in the working chamber 2, which may occur when the existing unpacking machine opens the chamber door to take out and replace the bag after unpacking the ton bag, polluting the environment and endangering the health of the workers.

The ends of the multiple support connecting rods 992 away from the corresponding rectangular sliders 991 are hinged to the outer wall of the sleeve 982.

[0041] After the two partition plates 253 are closed, it should be noted that the internal thread of the sleeve 982 is initially located on the upper side of the external thread groove of the annular plate 981, and the multiple bag cutters 989 are initially in a retracted state. The forward and reverse motor 1978 controls the transmission shaft 976 to drive the active bevel gear 977 to rotate. The active bevel gear 977 and the passive bevel gear 975 drive each other, driving the transmission barrel 971 to rotate. During this period, the transmission barrel 971 will drive the circular mounting plate 95 to move upward through the hollow screw 972 until the hollow screw 972 drives the annular limit plate 973 to slide upward. When the circular mounting plate 95 moves to the position of the internal thread of the transmission barrel 971, it will drive multiple support slide plates 987 to slide upward along the inner wall of the working chamber 2. The circular mounting plate 95 will also drive the sleeve 982, the conical seat 983 and multiple bag cutters 989 to move upward through the annular plate 981. At this time, the conical seat 983 and multiple bag cutters 989 will first perform preliminary piercing work on the bottom of the ton bag. Then, as the annular limiting plate 973 slides upward to the position of the internal thread of the transmission barrel 971, the hollow screw 972 will not be able to continue to move upward under the limiting action of the annular limiting plate 973.

[0042] At this time, the transmission barrel 971 will drive the hollow lead screw 972 to rotate synchronously. Under the limiting action of the telescopic rod 984, the transmission lead screw 974 will move upward until the transmission lead screw 974 drives the circular limit plate 979 to slide upward to the position of the internal thread of the hollow lead screw 972. Under the limiting action of the circular limit plate 979, the transmission lead screw 974 will not be able to move upward further. During the period when the transmission lead screw 974 is inserted into the annular plate 981, the transmission lead screw 974 will drive the annular plate 981 to rotate. The annular plate 981 will drive the conical... Both seat 983 and conical guide seat 985 move downwards. At this time, multiple limit slide rods 986 will perform adaptive sliding compensation along the circular mounting plate 95. When sleeve 982 moves downwards, under the action of multiple support connecting rods 992 and multiple rectangular sliders 991, multiple bag cutters 989 will rotate around the corresponding two lugs 988 respectively, becoming open, thereby achieving the effect of multiple bag cutters 989 cutting the side of the ton bag. At this time, the powder in the ton bag will be discharged from the ton bag and continue to be discharged from the discharge port of working chamber 2, and received by the external conveying equipment. To proceed with the next feeding step, after the powder in the ton bag has been completely discharged, the electric hoist 43 controls the hook to move the cut ton bag upwards to a height corresponding to the feed inlet of the working chamber 2. During this process, the hook will contact the two rectangular sliding plates 546 on the lower side, causing them to retract into their corresponding rectangular mounting slots 545. Then, the forward and reverse motor 978 controls the transmission shaft 976 to drive the active bevel gear 977 to rotate in the opposite direction. The active bevel gear 977 and the passive bevel gear 975 drive each other, causing the transmission barrel 971 to rotate in the opposite direction. 71 will sequentially drive the transmission screw 974 and hollow screw 972 to move downwards and return to their original positions. During this process, the sleeve 982, conical seat 983, conical guide seat 985 and multiple bag cutters 989 will all return to their original positions. The separating mechanism 5 and the bag breaking mechanism 9 work together to first perform preliminary cutting on the bottom of the ton bag in the lower working area through the conical seat 983 and multiple bag cutters 989. Then, the multiple bag cutters 989 are controlled to open and perform secondary cutting on the sides of the ton bag, effectively increasing the bag breaking effect and further improving the powder discharge effect after bag breaking.

[0043] See Figure 3 , Figure 7 and Figure 9The striking mechanism 7 includes two bearing seats 71 installed at the right end of the working chamber 2. A dual-axis motor 72 is installed at the right end of the working chamber 2 via a motor seat. The left and right output shafts of the dual-axis motor 72 are respectively fixedly connected to rotating shafts 73. The left and right rotating shafts 73 are respectively rotatably connected to the corresponding bearing seats 71. Both ends of the left and right rotating shafts 73 are equipped with bevel gears 74. Two striking parts 75 are symmetrically arranged at the front and rear of the working chamber 2. The striking part 75 includes a sliding striking plate 76 that is slidably installed between partition plate 51 and partition plate 53. Multiple elastic rubber balls 77 are evenly installed at the striking end of the sliding striking plate 76. Two upper and lower sliding rods 78 are slidably installed on the outer wall of the working chamber 2 at positions corresponding to the sliding striking plate 76. The ends of the upper and lower sliding rods 78 located inside the working chamber 2 are fixedly connected to the sliding striking plate 76. Two upper and lower sliding rods 78 are mounted together at one end outside the working chamber 2 with a rectangular push plate 79. A chamfered plate 80 is installed on the outer wall of the working chamber 2 at the position corresponding to the rectangular push plate 79. The rectangular push plate 79 is slidably connected to the chamfered plate 80 and is connected to the outer wall of the working chamber 2 by multiple compression springs. A support shaft 81 is rotatably mounted on the upper and lower inner walls of the chamfered plate 80. Cams 82 are fixedly sleeved at both ends of the support shaft 81. Both upper and lower cams 82 roll in contact with the rectangular push plate 79. A bevel gear 83 is fixedly sleeved on the support shaft 81 at the position above the lower cam 82. A connecting shaft 84 rotatably passes through the inner wall of the right end of the chamfered plate 80. Bevel gears 85 are installed at both ends of the connecting shaft 84. The left bevel gear 85 meshes with bevel gear 83, and the right bevel gear 85 meshes with bevel gear 74.

[0044] When the hook moves the cut ton bag upwards to the height corresponding to the feed inlet of the working chamber 2, the dual-shaft motor 72 controls the left and right rotating shafts 73 to drive the corresponding bevel gears 74 to rotate. The bevel gears 74 and 83 on the front and rear sides, along with the left and right bevel gears 85, drive the front and rear support shafts 81 to rotate synchronously. The front and rear support shafts 81 then drive the corresponding upper and lower cams 82 to rotate. The upper and lower cams 82 on the front and rear sides respectively push the corresponding rectangular push plates 79, causing them to move along the U-shaped plate 8. The inner wall slides back and forth. During this process, the two rectangular push plates 79 will drive the corresponding sliding plates 76 to slide back and forth through the corresponding upper and lower slide bars 78. It should be noted that the multiple elastic rubber balls 77 on the two sliding plates 76 are staggered. Whenever the two sliding plates 76 approach each other, they can beat the cut ton bag, thereby further removing any residual powder in the cut ton bag. After beating the cut ton bag is completed, the dual-axis motor 72 is controlled to stop working.

[0045] Next, the electric hoist 43 controls the hook to move the cut ton bag upwards to exit the working chamber 2. During this process, the wire rope on the electric hoist 43 will contact multiple rectangular sliding plates 546 on the upper and middle sides, causing them to retract into their corresponding rectangular mounting slots 545. After the hook moves the ton bag out of the working chamber 2, under the action of multiple compression springs, both the front and rear C-shaped sliding plates 543 will self-adaptively slide and compensate along their corresponding C-shaped mounting slots 542 to return to their original positions. Finally, the electric slide table 42 controls the electric hoist 43 to move to the left side of the slide rail 41. Then, the electric hoist 43 controls the hook to move the cut ton bag downwards to a suitable position. The cut ton bag is then manually removed, and the next ton bag to be transported is hooked up again by the hook. By repeating the above operation, the unpacking and conveying of ton bags can be repeated.
