Description

Technical Field

[0001] This invention relates to the field of crushing equipment technology, and in particular to a device for recycling and processing angle iron processing waste. Background Technology

[0002] In angle iron processing, it is often necessary to cut, punch, and bend angle iron, which generates a large amount of scrap, fragments, or waste. In order to make effective use of resources and reduce production costs, it is necessary to recycle the waste.

[0003] Current methods involve feeding waste into a crusher, which breaks down large pieces of waste. The crushed waste is then easier to classify, store, transport, and smelt. The current crushing method involves feeding waste into the crusher housing, where it is broken down into fragments by the crushing blades on two sets of crushing rollers.

[0004] After prolonged use, the blades of the crusher are prone to damage after repeated collisions with the angle iron scrap, which weakens the crusher's ability to crush scrap and requires replacement. Often, there are multiple crushers on a single crushing roller, so the equipment needs to be disassembled, and the crushers on the crushing roller need to be removed one by one until the damaged crusher is removed and replaced with a new one. Then the equipment needs to be reassembled, which makes the replacement of the crushers quite troublesome. Summary of the Invention

[0031] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0032] This application discloses a device for recycling and processing waste from angle iron processing. (Refer to...) Figure 1 The recycling and processing device includes a support frame 1, a crushing box 2, and crushing rollers 3. The crushing box 2 is installed on the top surface of the support frame 1. There are two crushing rollers 3, which are rotatably connected to the two ends of the crushing box 2 and are parallel to each other. Multiple rotating plates 4 and multiple partition plates 5 are installed on the crushing rollers 3. The partition plates 5 and rotating plates 4 are staggered, with a rotating plate 4 between two adjacent partition plates 5. The partition plates 5 on one crushing roller 3 are aligned with the rotating plates 4 on the other crushing roller 3. Multiple mounting grooves 41 are provided on the circumference of the rotating plates 4. There can be two, three, four, etc. In this embodiment, there are eight mounting grooves 41. A cutter 42 is installed in the mounting groove 41 and fits against the inner wall of the mounting groove 41. The cutter head of the cutter 42 extends out of the mounting groove 41. A positioning pin 43 is connected to the bottom surface of the mounting groove 41. The end face of the cutter 42 near the mounting groove 41 is provided with a positioning hole 421 for the insertion of the positioning pin 43. A fixing mechanism 6 for fixing the cutter 42 in the mounting groove 41 is installed on the partition plate 5.

[0033] Angle iron scrap is fed into the crushing box 2, driving two crushing rollers 3 to rotate in opposite directions. The crushing rollers 3 drive the rotating plate 4 and the partition plate 5, and the rotating plate 4 drives the cutter 42 to rotate. The cutter head of the cutter 42 crushes the angle iron scrap between the two crushing rollers 3. When the cutter head of the cutter 42 is damaged, the equipment is stopped. By rotating the crushing roller 3, the damaged cutter 42 is turned upwards, and the fixing mechanism 6 is released from fixing the cutter 42. The damaged cutter 42 can then be removed from the mounting slot 41 and replaced. The positioning hole 421 of the cutter 42 is aligned with the positioning pin 43, and the cutter 42 is inserted into the mounting slot 41. The positioning pin 43 is inserted into the positioning hole 421, and the cutter 42 is then fixed by the fixing mechanism 6. The angle iron can then continue to be crushed. The use of a split cutter 42 can improve the convenience of cutter 42 replacement and reduce the cost of cutter 42 replacement.

[0034] Each cutter 42 is fixed by a fixing mechanism 6. A partition plate 5 at the same end of the two crushing rollers 3 is a clearance partition plate 5015. The fixing mechanism 6 includes a first fixing rod 61, a second fixing rod 62, and a drive assembly 63. The first fixing rod 61 and the second fixing rod 62 have the same structure. The partition plate 5 is provided with eight first fixing holes 51 evenly arranged around the circumference of the partition plate 5. The first fixing holes 51 are used for inserting the first fixing rod 61. Each cutter 42 is provided with a second fixing hole 422 for inserting the second fixing rod 62. The first fixing holes 51 and the second fixing holes 422 are aligned one-to-one. The thickness of the partition plate 5 is equal to the thickness of the rotating plate 4, and the length of the first fixing rod 61 and the second fixing rod 62 are equal. The first fixing holes 51 of all partition plates 5 are aligned one by one, and the second fixing holes 422 in the cutters 42 on all rotating plates 4 are aligned one by one. The drive assembly 63 is installed on the partition plate 5 and is used to drive the first fixing rod 61 to slide towards the clearance partition plate 5015. The first fixing rod 61 in the clearance partition plate 5015 is shorter than the first fixing rod 61 in the other partition plates 5, and the first fixing rod 61 in the clearance partition plate 5015 slides away from the cutter 42.

[0035] When installing the cutter 42 on the crushing roller 3, first install the partition plate 5 and the rotating plate 4. Then, the drive assembly 63 in the clearance partition plate 5015 drives the first fixing rod 61 to slide away from the cutter 42, so that the first fixing hole 51 in the clearance partition plate 5015 makes room for the adjacent second fixing rod 62 to enter. Then, starting from the end closest to the clearance partition plate 5015, install the cutter 42. The second fixing rod 62 is placed in the second fixing hole 422 of the cutter 42, and the cutter 42 is installed in the mounting groove 41. Driven by the drive assembly 63 on the adjacent partition plate 5. The first fixing rod 61 in the first fixing hole 51 slides into the second fixing hole 422. The first fixing rod 61 pushes the second fixing rod 62. Part of the first fixing rod 61 enters into the second fixing hole 422, and part of the second fixing rod 62 enters into the first fixing hole 51 of the partition plate 5015. This divides the interior of the second fixing hole 422 of the tool 42 into the first fixing rod 61 and the second fixing rod 62. The tool 42 is fixed by the first fixing rod 61 and the second fixing rod 62. Space is also provided in the partition plate 5 for the subsequent insertion of the second fixing rod 62. The subsequent installation of the tool 42 is carried out in the above manner.

[0036] When it is necessary to disassemble the tool 42, the drive assembly in the same row as the target tool 42 needs to be located, and the tool 42 should be facing upwards. Drive the drive assembly 63 on the side of the target tool 42 away from the clearance partition 5015 to move the first fixing rod 61 back into the first fixing hole 51 and the second fixing rod 62 back into the second fixing hole 422. Finally, drive the target tool 42 closer to the drive assembly 63 on the side of the clearance partition 5015 to move the second fixing rod 62 in the target tool 42 back into the second fixing hole 422. At this time, the target tool 42 can be replaced. After replacement, fix the tool 42 according to the installation method.

[0037] The first fixing rod 61 includes a column 611 and a sliding plate 612. The sliding plate 612 is integrally formed on the circumferential surface of the column 611 and slides within the first fixing hole 51 and the second fixing hole 422. The drive assembly 63 includes a rotating shaft 631 and a gear 632. The rotating shaft 631 is rotatably connected to the partition plate 5, and the gear 632 is coaxially connected to the outer circumferential surface of the rotating shaft 631. A row of teeth 613 is integrally formed on the side of the sliding plate 612 of the first fixing rod 61, and the teeth 613 mesh with the gear 632. A hexagonal groove 6311 is provided on the end face of the rotating shaft 631 for inserting a hexagonal wrench. A moving groove 614 for moving the teeth 613 is provided in both the first fixing hole 51 and the second fixing hole 422. A moving plate 615 that slides on the inner wall of the moving groove 614 is integrally formed on the side of the sliding plate 612 of the second fixing rod 62.

[0038] When it is necessary to drive the first fixed rod 61 to slide, the hex wrench is inserted into the hexagonal groove 6311 of the knife. The hex wrench drives the rotating shaft 631 to rotate. The rotating shaft 631 drives the gear 632 to rotate. The gear 632 drives the teeth 613. The teeth 613 drive the column 611 to slide through the sliding plate 612. At this time, the first fixed rod 61 slides and can push the second fixed rod 62.

[0039] The partition plate 5 has multiple insertion holes 52 on its periphery, which are aligned with the rotating shaft 631. Each insertion hole 52 is fitted with a mounting base 7. The rotating shaft 631 is rotatably connected to the mounting base 7. The mounting base 7 has a notch 71 on its periphery for the first fixing rod 61 and the tooth 613 to slide. The gear 632 extends out of the notch 71 and meshes with the tooth 613.

[0040] The mounting base 7 has a positioning strip 72 on its periphery, and the inner wall of the insertion hole 52 has a positioning groove 53 for the positioning strip 72 to be inserted. The mounting base 7 has screws 73 on both sides, which are threaded into the partition plate 5. The end face of the mounting base 7 has a positioning port 74 for the screw 73 nut to enter, and the screw 73 nut is pressed against the bottom surface of the positioning port 74.

[0041] When it is necessary to install the rotating shaft 631 inside the partition plate 5, the mounting base 7 with the rotating shaft 631 is inserted into the socket 52. First, the positioning strip 72 is aligned with the positioning groove 53, the mounting base 7 is inserted, and then two screws 73 are screwed into the partition plate 5. The nuts of the screws 73 enter the positioning port 74, and the nuts of the screws 73 fix the mounting base 7, thus realizing the installation of the mounting base 7 and the rotating shaft 631.

[0042] The bottom of the mounting base 7 is provided with a movable groove 75 for the rotation shaft 631 to move in the axial direction. A spring piece 76 is provided in the movable groove 75. One end of the spring piece 76 is pressed against the bottom surface of the rotation shaft 631, and the other end of the spring piece 76 is pressed against the bottom surface of the movable groove 75. The part of the mounting base 7 above the gear 632 is provided with a toothed groove 77 for the top of the gear 632 to enter. The toothed groove 77 is engaged with the gear 632.

[0043] When it is necessary to drive the rotating shaft 631 to rotate, the rotating shaft 631 is pressed down by the hex wrench. The rotating shaft 631 drives the gear 632 to slide into the movable groove 75. The rotating shaft 631 presses down the spring piece 76, and the top of the gear 632 moves out of the tooth groove 77. The gear 632 is freed from the constraint of the tooth groove 77, and can then drive the rotating shaft 631 to rotate. After the rotating shaft 631 has finished rotating, the pressure of the hex wrench on the rotating shaft 631 is released. Under the action of the spring piece 76, the rotating shaft 631 moves upward. After the gear 632 is aligned with the tooth groove 77, the gear 632 enters the tooth groove 77. At this time, the tooth groove 77 restricts the rotation of the gear 632, and the gear 632 can fix the teeth 613.

[0044] A wedge block 54 is connected to the inner wall of the first fixing hole 51 of the partition plate 5 away from the clearance partition plate 5015. The wedge block 54 is located at the opening of the first fixing hole 51 away from the clearance partition plate 5015, and the side of the wedge block 54 is in contact with the side of the tooth 613. A wedge block 54 is also provided in the first fixing hole 51 of the clearance partition plate 5015. The wedge block 54 is located at the opening of the first fixing hole 51 away from the cutter 42, and the side of the wedge block 54 is in contact with the side of the tooth 613.

[0045] When the first fixed rod 61 is driven to move within the first fixed hole 51, due to the presence of the wedge block 54, the wedge block 54 blocks the teeth 613. The first fixed rod 61 at the far end is not easily slipped out of the first fixed hole 51 under the constraint of the teeth 613, and the first fixed rod 61 at the end is not easily rubbed against the inner wall of the crushing box 2.

[0046] Two motors 8 are installed on the top surface of the support frame 1. The two motors 8 are located on both sides of the crushing box 2, and the two motors 8 drive the two crushing rollers 3 to rotate through pulleys.

[0047] The bottom of the crushing box 2 is connected to the collection bin 21, and the opening of the collection bin 21 is connected to the bottom of the crushing box 2; the bottom surface of the support frame 1 is suspended by the collection hopper 22, which is located below the collection bin 21. One end of the collection hopper 22 is tilted downward and has a discharge port 221.

[0048] Two first connecting frames 11 are connected to both sides of the support frame 1. A pull rod 12 is connected to the bottom of the first connecting frame 11. A base plate 13 is connected to the bottom of the pull rod 12. A spring 14 is sleeved on the pull rod 12. The bottom end of the spring 14 is pressed against the top surface of the base plate 13. A top plate 15 is sleeved above the pull rod 12. The bottom surface of the top plate 15 is pressed against the top surface of the spring 14. A second connecting frame 16 is connected to the periphery of the top plate 15. The bottom of the second connecting frame 16 is connected to the side of the collecting hopper 22.

[0049] A counterweight 23 is connected to the bottom of the hopper 22, which is away from the discharge port 221.

[0050] The angle iron crushed in the crushing box 2 falls into the collecting hopper 22 through the collecting bin 21. Since the collecting hopper 22 is set at an inclination, the waste in the collecting hopper 22 is discharged to the outside through the discharge port 221. A material transport vehicle can be set below the collecting hopper 22, and the waste in the collecting hopper 22 can fall directly into the material transport vehicle. Since the collecting hopper 22 is supported by the spring 14, when the waste falls into the collecting hopper 22, the collecting hopper 22 will shake under the action of the spring 14, making it easier for the waste to be discharged from the discharge port 221.

[0051] The implementation principle of the angle iron processing waste recycling device in this application embodiment is as follows: When the blade 42 is damaged, the equipment is stopped, the damaged blade 42 is turned upward by rotating the crushing roller 3, the fixing mechanism 6 is released from fixing the blade 42, and the damaged blade 42 can be removed from the mounting groove 41. The blade 42 is then replaced. The positioning hole 421 of the blade 42 is aligned with the positioning pin 43, the blade 42 is inserted into the mounting groove 41, the positioning pin 43 is inserted into the positioning hole 421, and the blade 42 is fixed by the fixing mechanism 6. The angle iron can then continue to be crushed. The use of a split blade 42 can improve the convenience of blade 42 replacement and reduce the cost of blade 42 replacement.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
