Description

Technical Field

[0001] This invention belongs to the field of scraper preparation technology, specifically a scraper preparation device and preparation method for iron-coated rock surface. Background Technology

[0002] With the development of intelligent and intensive coal mining, ultra-long fully mechanized mining faces have become the main layout method for underground production, which can significantly improve single-face output, coal mining efficiency, reduce mining frequency, and improve overall economic benefits. However, the increase in the length of scraper conveyors leads to an increase in the number and size of scrapers, resulting in increased overall machine weight, drive power and energy consumption, and more prominent chain tension and wear issues. Existing conveyor scrapers are mostly integral metal structures, which, although strong and impact-resistant, have problems such as heavy weight, high energy consumption and manufacturing costs, and limited wear life. In ultra-long working faces, the use of a large number of metal scrapers not only increases the difficulty of equipment transportation and installation, but also causes the conveying system to operate under high load for a long time, affecting the stability of the drive unit and chain drive system.

[0003] To reduce scraper weight and energy consumption, resin-based composite materials are used to replace the traditional metal scraper body. This material is composed of inorganic particles and a resin matrix. However, due to current technological limitations, resin-based composite materials suffer from insufficient toughness and impact resistance. Under high-load conditions such as coal cutting or foreign object impacts, the surface layer is prone to cracking or peeling, severely affecting its service life. This defect is particularly pronounced in the high-frequency impact environment of ultra-long working faces. Therefore, to compensate for the material's brittleness, coating the impact-affected surface of the scraper with sheet metal has become an effective structural reinforcement measure. To this end, this invention proposes a device and method for preparing a rock-based scraper with sheet metal coating to address the aforementioned problems. Summary of the Invention

[0014] This invention also provides a method for preparing a scraper for coating iron on the surface of a rock base, based on the scraper preparation device for coating iron on the surface of a rock base as described above, comprising the following steps: Step 1: Before using this device, the staff first obtains the watch case sheet through a stamping process; Step 2: When using this device, the operator installs the entire device in the required position and fixes the flexible tube to the screw-type injection molding machine. The controller then controls the hydraulic traction rod to retract, thereby moving the mold cover to the left, so that the mold cover moves away from the bottom of the mold. Step 3: Further, the controller controls several rack connecting columns to work in sequence, thereby driving several racks to move outward in sequence until the locking boss and wedge block engage. At this time, the operator installs the watch case sheet into the top mold groove as part of the mold cavity. At this time, the controller controls the rack connecting columns to work in reverse, thereby causing the stop block to clamp the watch case sheet. At this time, the hydraulic traction rod is controlled to reset, thereby causing the stop block to fit tightly with the sealing groove. Step Four: Further, the controller controls the first rack connecting column to work again, causing the first rack to move outwards, which in turn moves the first stop block outwards, which in turn moves the first connecting plate outwards, which in turn moves the first pin block outwards. At this time, due to the action of the pin shaft and pin spring, the wedge block moves outwards, causing the first set of wedge blocks to fit tightly against the inner surface of the first sliding boss, thus locking the first rock base scraper body. Then, the controller controls the first rack connecting column to work in reverse, causing the first rack to reset. When the first pin block needs to engage with the first locking hole, the controller controls the first... The motor operates, causing the first pin positioning rod to move outward again. At this time, due to the sliding connection between the sliding boss and the pin positioning rod, the first sliding boss and the first locking boss are in close contact, allowing the first set of wedge blocks to slide past the first sliding boss and the first locking boss, thus facilitating the pin block to move inward. This allows the first pin block to engage with the first locking hole, and the first stop block to once again engage with the first sealing groove. Furthermore, the controller controls the remaining rack connecting columns to work sequentially according to the above steps, so that each pin block engages with its external locking hole, thereby ensuring the locking of the mold cover and the mold bottom. Step 5: Further, the controller controls the slider to move and the push rod to extend, thereby driving the slider to descend, so that the injection tube is inserted into the injection hole and the bottom of the slider is in close contact with the bottom of the mold. At this time, the controller controls the locking block to move and the push rod to extend, so that the locking block moves forward and the locking block is in close contact with the locking groove. Step Six: Further, the controller controls the injection molding machine to work, thereby transporting the injection molding liquid through the flexible tube and injection tube into the bottom mold groove. At this time, the controller controls the dual-head motor to work, thereby causing the three eccentric wheels to rotate due to the action of the belt, which causes the mold cover to vibrate, thereby causing the air inside the injection molding liquid to rise and be discharged through the exhaust hole. Step 7: The controller controls the injection molding machine to continue working. When the bottom mold groove is filled with injection liquid, the injection liquid pressure will push the sealing block to move upward, so that the sealing block is in close contact with the sealing cavity. At this time, due to the action of the eccentric wheel, there is no air inside the bottom mold groove. When the pressure sensor inside the sealing block senses that the pressure has reached the required value, the controller controls the injection molding machine to stop working. At this time, the controller controls the locking block moving push rod and the slider moving push rod to work together to pull out the injection tube. Step 8: At this time, the injection liquid inside the bottom mold groove can be cooled due to the function of the cooling holes. After a certain cooling time, the injection liquid forms the rock base scraper body. At this time, the rock base scraper body is fixed with the iron sheet of the casing, thus forming the rock base surface iron-clad scraper. At this time, the controller sequentially controls several rack connecting columns to work again, so that the pin block disengages from the locking hole and the rack connecting column is reset and the stop block is locked with the iron sheet of the casing again. Step Nine: At this point, the controller retracts the hydraulic traction rod, causing the base plate to move and the top column to move until the top column is flush with the boss. The rock base surface iron-coated scraper is now positioned between the two sets of buffer plates. The controller then sequentially controls several rack connecting columns to operate again, causing several stops to move away from the rock base surface iron-coated scraper. The controller then continues to retract the hydraulic traction rod, causing the base plate and mold cover to move further to the left. The top plate and guide column stop moving due to the action of the top column, causing the bottom mold slot to stop moving. The rock base surface iron-coated scraper is then pushed out of the top mold slot and falls onto the buffer plate. The buffer spring causes the scraper to slowly fall onto the conveyor belt. The controller then controls the conveyor motor to operate, conveying the scraper out of the entire device, completing the preparation process. The controller then resets the hydraulic traction rod, and the top rod spring resets it. This process is repeated to complete the production of the next rock base surface iron-coated scraper.

[0015] Compared with the prior art, the beneficial effects of the present invention are: (1) This device uses a hydraulic traction rod to extend and retract, which can drive the base plate to move, thereby driving the stepped traction column to move, and thus driving the mold cover to move, so that the mold cover is separated from the mold bottom. Furthermore, the top column and the boss can cooperate to make the positioning plate stop when the hydraulic traction rod moves, so that the iron sheet of the watch case can be pushed out through the top rod, thereby facilitating the ejection of the iron-clad scraper, thereby realizing automation and improving the production efficiency. The buffer plate is used to buffer the iron-clad scraper, thereby preventing the iron-clad scraper body from separating from the watch case iron sheet, thereby ensuring the safety of the iron-clad scraper and the safety of the conveyor belt. This device realizes the stable pre-positioning of the watch case iron sheet, the one-time forming of the scraper, and automatic demolding and conveying, reducing manual intervention. It has a compact structure and reliable operation, and can significantly improve the forming consistency and production efficiency of the scraper. In this invention, the watch case iron sheet is pre-placed into the mold before injection molding, so that it As part of the mold cavity, it participates in scraper forming and directly forms the rock-based scraper body during injection, pressure holding, and cooling processes. This avoids subsequent assembly steps, simplifies production, and reduces manufacturing costs. Furthermore, the preparation method and manufacturing equipment of this invention are well-matched, enabling continuous and automated preparation of rock-based surface-coated iron scrapers. This is conducive to large-scale production and has good industrial application prospects. The rock-based surface-coated iron scraper uses rock-based material to form the scraper body and has a surface iron sheet. While ensuring the overall strength and wear resistance of the scraper, it effectively reduces the scraper's weight and improves its impact resistance. It balances lightweight, high wear resistance, and economy, making it suitable for long-term use under high-impact and high-wear conditions. Moreover, the rock-based material can be low-cost raw materials such as coal gangue, which are readily available in mining operations, realizing the resource reuse of mining solid waste. (2) This device uses a pressure plate and a top plate to position the positioning plate. At the same time, the motor can drive the gear to rotate, thereby driving the rack to move, which makes it easy to clamp the iron sheet of the watch case and easy to disassemble the iron sheet of the watch case, thus ensuring the injection molding effect. At the same time, due to the effect of the connecting nail, the friction between the rock base scraper body and the iron sheet of the watch case can be increased, thus ensuring the stability of the iron-clad scraper, thus ensuring the preparation effect. (3) This device uses the mold cover and mold bottom to form the rock base scraper body. The locking block can be moved by the extension and retraction of the locking block push rod. The sliding block can be raised and lowered by the sliding block push rod. Furthermore, the locking block and locking groove can be used to ensure the stability of the sliding block, thereby ensuring the stability of the injection tube. This prevents the injection tube from being ejected due to excessive pressure inside the bottom mold groove, thus ensuring the safety of the injection tube and the safety of the workers. At the same time, the sliding block push rod and the locking block push rod facilitate the removal of the injection tube, thereby preventing the injection liquid from cooling inside the injection tube and preventing the injection tube from being blocked. (4) This device works by a double-headed motor, which can drive the main pulley and the eccentric wheel at its bottom to rotate. As a result, due to the action of the slider positioning groove, the locking block, and the slider, the flexible tube is driven to rotate, which in turn drives all the eccentric wheels to rotate. This can drive the mold cover to vibrate, thereby expelling the air inside the bottom mold groove, thus expelling the air inside the injection-molded rock base scraper body, thereby ensuring the preparation effect. (5) This device uses a rack and pinion positioning pin to position the rack. The rack can move the stop block by moving, which facilitates the movement of the pin. The pin and the locking hole can lock the mold cover and the mold bottom, thereby preventing the hydraulic traction rod from being continuously stressed. At the same time, it prevents the mold cover from splashing due to excessive internal pressure in the mold cover and the mold bottom, thus ensuring the safety of the staff.

Each pin block positioning rod 605 is slidably connected to the rack connecting post 6 at one end. When the watch case sheet 508 needs to be installed, the controller 101 controls several rack connecting posts 6 to work sequentially, thereby driving several racks 603 to move outward sequentially until the locking boss 612 engages with the wedge block 616. At this time, the operator installs the watch case sheet 508 into the top mold groove 510. Then, the controller 101 controls the rack connecting posts 6 to work in reverse, thereby causing the stop block 608 to clamp the watch case sheet 508. At this time, the controller controls the hydraulic traction rod 2 to reset, thereby causing the stop block 608 to fit tightly against the sealing groove 503. Further, the controller 101 controls the first rack connecting post 6 to work again, thereby driving the second rack connecting post 6 to work in reverse. One of the racks 603 moves outward, thereby causing the first stop block 608 to move outward, which in turn causes the first connecting plate 606 to move outward, which in turn causes the first pin block 607 to move outward. At this time, due to the action of the pin rod 614 and the pin spring 615, the wedge block 616 moves outward, so that the first set of wedge blocks 616 is in close contact with the inner surface of the first sliding boss 611, thereby locking the first rock base scraper body 507, thereby moving the first rock base scraper body 507 away from the mold cover 5. At this time, the first rack connecting column 6 is controlled to work in reverse, thereby causing the first rack 603 to reset. When the first pin block 607 is needed... When the first locking hole 504 is engaged, the first motor 601 is controlled to operate again, thereby driving the first pin positioning rod 605 to move outward again until the inner side of the first pin 607 is in close contact with the inner side of the first positioning groove 617. At this time, the first rack 603 continues to move outward, causing the first set of wedge blocks 616 to slide past the first sliding boss 611 and the first locking boss 612. Further, the controller 101 controls the first motor 601 to operate in reverse, causing the first pin 607 to move inward. At this time, since the sliding boss 611 is slidably connected to the pin positioning rod 605, the first sliding boss 607 moves inward. The boss 611 is in close contact with the first locking boss 612. At this time, due to the sliding connection between the sliding boss 611 and the pin positioning rod 605, the first sliding boss 611 and the first locking boss 612 are in close contact, which facilitates the inward movement of the pin 607, thereby facilitating the engagement of the first pin 607 with the first locking hole 504, and causing the first stop 608 to once again be in close contact with the first sealing groove 503. Furthermore, the controller 101 controls the remaining rack connecting columns 6 to work sequentially according to the above steps, thereby causing each pin 607 to engage with its external locking hole 504, thus ensuring that the mold cover 5 and the mold bottom 501 are locked.

[0024] This embodiment provides a method for preparing a scraper for coating iron on the surface of a rock base, based on the aforementioned apparatus for preparing a scraper for coating iron on the surface of a rock base, including the following steps: Step 1: Before using this device, the staff first obtains the watch case sheet (508) through a stamping process. Step 2: When using this device, the operator installs the entire device in the required position and fixes the flexible tube 806 to the screw-type injection molding machine. The controller 101 then controls the hydraulic traction rod 2 to retract, thereby driving the mold cover 5 to move to the left, so that the mold cover 5 moves away from the mold bottom 501. Step 3: Further, the controller 101 controls several rack connecting columns 6 to work in sequence, thereby driving several racks 603 to move outward in sequence until the locking boss 612 engages with the wedge block 616. At this time, the operator installs the watch case sheet 508 into the top mold groove 510 as part of the mold cavity. At this time, the controller 101 controls the rack connecting columns 6 to work in reverse, thereby causing the stop block 608 to clamp the watch case sheet 508. At this time, the hydraulic traction rod 2 is controlled to reset, thereby causing the stop block 608 to be tightly attached to the sealing groove 503. Step 4: Further, the controller 101 controls the first rack connecting post 6 to work again, thereby driving the first rack 603 to move outward, thereby driving the first stop block 608 to move outward, thereby driving the first connecting plate 606 to move outward, thereby driving the first pin block 607 to move outward. At this time, due to the action of the pin rod 614 and the pin spring 615, the wedge block 616 moves outward, thereby making the first set of wedge blocks 616 tightly attached to the inner surface of the first sliding boss 611, thereby locking the first rock base scraper body 507. At this time, the controller controls the first rack connecting post 6 to work in reverse, thereby making the first rack 603 reset. When the first pin block 607 needs to be engaged in the first locking hole 504, the controller controls the first motor 601 to work again. The action causes the first pin positioning rod 605 to move outward again. At this time, due to the sliding connection between the sliding boss 611 and the pin positioning rod 605, the first sliding boss 611 and the first locking boss 612 are in close contact, so that the first set of wedge blocks 616 slides over the first sliding boss 611 and the first locking boss 612, which facilitates the pin block 607 to move inward, so that the first pin block 607 is engaged with the first locking hole 504, and the first stop block 608 is once again in close contact with the first sealing groove 503. Further, the controller 101 controls the remaining rack connecting columns 6 to work in sequence according to the above steps, so that each pin block 607 is engaged with its external locking hole 504, thereby ensuring that the mold cover 5 and the mold bottom 501 are locked. Step 5: Further, the controller 101 controls the slider to move the push rod 804 to extend, thereby driving the slider 803 to descend, so that the injection tube 807 is inserted into the injection hole 808, and the bottom of the slider 803 is in close contact with the mold bottom 501. At this time, the controller 101 controls the locking block to move the push rod 8 to extend, so that the locking block 802 moves forward, thereby making the locking block 802 in close contact with the locking groove 809. Step Six: Further, the controller 101 controls the injection molding machine to work, thereby transporting the injection molding liquid through the flexible tube 806 and the injection tube 807 to the bottom mold groove 505. At this time, the controller 101 controls the dual-head motor 7 to work, thereby causing the three eccentric wheels 707 to rotate due to the action of the belt 705, thereby causing the mold cover 5 to vibrate, thereby causing the air inside the injection molding liquid to rise and be discharged through the exhaust hole 903. Step 7: Controller 101 controls the injection molding machine to continue working. When the bottom mold groove 505 is filled with injection liquid, the injection liquid pressure will push the sealing block 901 to move upward, so that the sealing block 901 is in close contact with the sealing cavity 902. At this time, due to the action of the eccentric wheel 707, there is no air inside the bottom mold groove 505. When the pressure sensor inside the sealing block 901 senses that the pressure has reached the required value, controller 101 controls the injection molding machine to stop working. At this time, controller 101 controls the locking block moving push rod 8 and the slider moving push rod 804 to work together to pull out the injection tube 807. Step 8: At this time, the injection liquid inside the bottom mold groove 505 can be cooled by the cooling hole 502. After cooling for a certain period of time, the injection liquid forms the rock base scraper body 507. At this time, the rock base scraper body 507 is fixed with the iron sheet 508 of the watch case, thus forming the rock base surface iron-clad scraper. At this time, the controller 101 controls several rack connecting columns 6 to work again in sequence, so that the pin block 607 is disengaged from the locking hole 504 and the rack connecting column 6 is reset and the stop block 608 is locked with the iron sheet 508 of the watch case again. Step Nine: At this point, controller 101 controls the hydraulic traction rod 2 to retract, thereby moving the base plate 201 and the top column 4 until the top column 4 is in close contact with the boss 204. At this time, the iron-coated scraper on the rock base surface is located in the middle of the two sets of buffer plates 304. Controller 101 sequentially controls several rack connecting columns 6 to work again, thereby moving several stops 608 away from the iron-coated scraper on the rock base surface. At this time, controller 101 controls the hydraulic traction rod 2 to continue retracting, thereby moving the base plate 201 and the mold cover 5 to the left. At this time, due to the action of the top column 4, the top plate 401 and the guide column 402 stop moving, thereby making the bottom mold groove... 505 stops moving, thus pushing the rock base surface iron-coated scraper out of the top mold groove 510, causing the rock base surface iron-coated scraper to fall onto the buffer plate 304. At this time, due to the action of the buffer spring 305, the rock base surface iron-coated scraper slowly falls onto the conveyor belt 301. At this time, the controller 101 controls the conveyor motor 3 to work, thus conveying the rock base surface iron-coated scraper out of the entire device, thereby completing the preparation work. At this time, the controller 101 controls the hydraulic traction rod 2 to reset. At this time, due to the action of the top rod spring 406, the top rod 405 resets. Further, the above work is repeated to complete the production of the next rock base surface iron-coated scraper.

10. A method for preparing a scraper for coating iron on the surface of a rock base, based on the apparatus for preparing a scraper for coating iron on the surface of a rock base as described in claim 9, characterized in that: Includes the following steps: Step 1: Before using this device, the staff first obtains the watch case sheet (508) through a stamping process. Step 2: When using this device, the staff will install the entire device in the required position and fix the flexible tube (806) to the screw injection molding machine. The controller (101) will then control the hydraulic traction rod (2) to retract, thereby driving the mold cover (5) to move to the left, so that the mold cover (5) moves away from the bottom of the mold (501). Step 3: Further, the controller (101) controls several rack connecting columns (6) to work in sequence, thereby driving several racks (603) to move outward in sequence until the locking boss (612) and the wedge block (616) are engaged. At this time, the operator installs the watch case sheet (508) into the top mold groove (510) as part of the mold cavity. At this time, the controller (101) controls the rack connecting columns (6) to work in reverse, thereby making the stop block (608) clamp the watch case sheet (508). At this time, the hydraulic traction rod (2) is controlled to reset, thereby making the stop block (608) and the sealing groove (503) fit tightly. Step 4: Further, the controller (101) controls the first rack connecting column (6) to work again, thereby driving the first rack (603) to move outward, thereby driving the first stop (608) to move outward, thereby driving the first connecting plate (606) to move outward, thereby driving the first pin block (607) to move outward. At this time, due to the action of the pin rod (614) and the pin spring (615), the wedge block (616) moves outward, thereby making the first set of wedge blocks (616) tightly attached to the inner surface of the first sliding boss (611), thereby locking the first rock base scraper body (507). At this time, the controller controls the first rack connecting column (6) to work in reverse, thereby making the first rack (603) reset. When the first pin block (607) needs to be inserted into the first locking hole (504), the controller controls the first motor (601) to work again. This causes the first pin positioning rod (605) to move outward again. At this time, due to the sliding connection between the sliding boss (611) and the pin positioning rod (605), the first sliding boss (611) and the first locking boss (612) are in close contact, so that the first set of wedge blocks (616) slides over the first sliding boss (611) and the first locking boss (612), thus facilitating the pin block (607) to move inward, so that the first pin block (607) is engaged with the first locking hole (504), and the first stop block (608) is once again in close contact with the first sealing groove (503). Further, the controller (101) controls the remaining rack connecting columns (6) to work in sequence according to the above steps, so that each pin block (607) is engaged with its external locking hole (504), thus ensuring that the mold cover (5) and the mold bottom (501) are locked. Step 5: Further, the controller (101) controls the slider moving push rod (804) to extend, thereby driving the slider (803) to descend, so that the injection tube (807) is inserted into the injection hole (808), and the bottom of the slider (803) is in close contact with the bottom of the mold (501). At this time, the controller (101) controls the locking block moving push rod (8) to extend, so that the locking block (802) moves forward, thereby making the locking block (802) in close contact with the locking groove (809); Step 6: Further, the controller (101) controls the injection molding machine to work, thereby transporting the injection liquid through the flexible tube (806) and injection tube (807) to the bottom mold groove (505). At this time, the controller (101) controls the dual-head motor (7) to work, thereby causing the three eccentric wheels (707) to rotate due to the action of the belt (705), thereby causing the mold cover (5) to vibrate, thereby causing the air inside the injection liquid to rise and be discharged through the exhaust hole (903); Step 7: The controller (101) controls the injection molding machine to work continuously. When the bottom mold groove (505) is filled with injection liquid, the injection liquid pressure will push the sealing block (901) to move upward, so that the sealing block (901) and the sealing cavity (902) are tightly attached. At this time, due to the action of the eccentric wheel (707), there is no air inside the bottom mold groove (505). When the pressure sensor inside the sealing block (901) senses that the pressure has reached the required value, the controller (101) controls the injection molding machine to stop working. At this time, the controller (101) controls the locking block moving push rod (8) and the slider moving push rod (804) to work together to pull out the injection tube (807). Step 8: At this time, the injection liquid inside the bottom mold groove (505) can be cooled by the cooling hole (502). After cooling for a certain period of time, the injection liquid forms the rock base scraper body (507). At this time, the rock base scraper body (507) is fixed with the iron sheet of the watch case (508), thus forming a rock base surface iron-coated scraper. At this time, the controller (101) controls several rack connecting columns (6) to work again in sequence, so that the pin block (607) is disengaged from the locking hole (504) and the rack connecting column (6) is reset and the stop block (608) is locked with the iron sheet of the watch case (508) again. Step Nine: At this time, the controller (101) controls the hydraulic traction rod (2) to retract, thereby driving the base plate (201) to move, thereby driving the top column (4) to move, until the top column (4) is close to the boss (204). At this time, the rock foundation surface iron scraper is located in the middle of the two sets of buffer plates (304). The controller (101) controls several rack connecting columns (6) to work again in sequence, thereby causing several stops (608) to move away from the rock foundation surface iron scraper. At this time, the controller (101) controls the hydraulic traction rod (2) to continue to retract, thereby causing the base plate (201) and the mold cover (5) to continue to move to the left. At this time, due to the action of the top column (4), the top plate (401) and the guide column (402) stop moving, thereby The bottom mold groove (505) stops moving, thereby pushing the rock base surface iron-coated scraper out of the top mold groove (510), so that the rock base surface iron-coated scraper falls onto the buffer plate (304). At this time, due to the action of the buffer spring (305), the rock base surface iron-coated scraper slowly falls onto the conveyor belt (301). At this time, the controller (101) controls the conveyor motor (3) to work, thereby conveying the rock base surface iron-coated scraper out of the entire device, thus completing the preparation work. At this time, the controller (101) controls the hydraulic traction rod (2) to reset. At this time, due to the action of the top rod spring (406), the top rod (405) is reset. Further, the above work is repeated, thereby completing the production work of the next rock base surface iron-coated scraper.
