[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0018] Reference Figure 1-8 A slit bushing preparation device comprises an equipment body 1, a winding roller 2 is installed on the outer side wall of the equipment body 1, a discharge box 3 is fixedly connected to the side of the winding roller 2, a conveying member 4 is arranged on the outer side wall of the equipment body 1, a cleaning mechanism is arranged on the conveying member 4, and the bushing coil is cleaned before winding, the cleaning mechanism comprises a clamping roller 7 installed in the conveying member 4, a slide rail 12 is fixedly connected between the conveying members 4 on both sides, a starting motor 8 is fixedly connected to the upper and lower sides of the left conveying member 4, a reciprocating screw 9 is fixedly connected to the output end of the starting motor 8, and a tail bump 13 is fixedly connected to the upper and lower sides of the right conveying member 4; When in use, the winding roller 2 will rotate to transport the pre-prepared coil to the discharge box 3, and the transported coil through the discharge box 3 will enter the conveying member 4. When the coil enters the conveying member 4, the sensor built into the equipment body 1 will stop the clamping roller 7 from rotating (this is the prior art and will not be elaborated on in detail), so that a part of the coil stays between the two conveying members 4, waiting for the cleaning box 11 to be cleaned. When the cleaning box 11 needs to be cleaned, the operator can turn on the starting motor 8 to drive the reciprocating screw 9 to rotate. When the reciprocating screw 9 rotates, the cleaning box 11 will be moved by the driving member 10. When the cleaning box 11 moves to the left, the rollers 14 on both sides of the cleaning box 11 will roll in the process of contacting with the slide rail 12. When the rollers 14 roll, the driving rod 28 will rotate synchronously. Under the action of the transmission belt 29, the pulley 30 will drive the stirring rod 26 to rotate in the storage box 20. At this time, the multiple stirring shafts 27 will stir the lubricant in the storage box 20 during the rotation of the stirring rod 26. Stirring can ensure that the components of the lubricant are evenly distributed, avoid separation or precipitation, and remove bubbles, so as to ensure the lubricating effect of the lubricant on the bushing coil; The end of the reciprocating screw 9 is rotatably connected with the tail protrusion 13, and a driving member 10 is threadedly sleeved on the outer wall of the reciprocating screw 9. A cleaning box 11 is fixedly connected below the driving member 10. Both sides of the cleaning box 11 are rotatably connected with rollers 14, and the rollers 14 are in rotational contact with the slide rails 12. A cleaning box 15 is installed on the inner wall of the cleaning box 11, and a cleaning scraper 16 is slidably connected to the inner wall of the cleaning box 15. A plurality of telescopic rods 17 are fixedly connected to the upper end of the cleaning scraper 16. A smoothing scraper 18 is arranged behind the cleaning scraper 16, and an upper and lower electric rods 19 are fixedly connected to the upper end of the smoothing scraper 18. The ends of the upper and lower electric rods 19 away from the smoothing scraper 18 are fixedly connected to the inner wall of the cleaning box 11; When the cleaning box 11 moves to the left to stir the lubricant in the storage box 20, the operator can control the telescopic rod 17 to extend so that the cleaning scraper 16 contacts the surface of the coil. When the cleaning scraper 16 contacts the surface of the coil, the dust and impurities on the surface of the coil are scraped and cleaned, which is convenient for the subsequent application of lubricant. The smearing mechanism is arranged in the cleaning mechanism and is linked with the cleaning mechanism. When the cleaning mechanism finishes cleaning the surface of the coil, the lubricant is smeared on the surface of the coil. The smearing mechanism includes a driving rod 28 fixedly connected to the outer wall of the roller 14, and the end of the driving rod 28 is fixedly connected to a one-way toothed disc 35. The outer wall of the one-way toothed disc 35 is rotatably connected to a reciprocating turntable 25. The inner wall of the reciprocating turntable 25 is provided with a plurality of mounting grooves 32. The inner walls of the plurality of mounting grooves 32 are all rotatably connected to a one-way toothed disc 35. The one-way baffle 34 is provided with a pressing spring 33 on the outer side wall of the one-way baffle 34, the one-way baffle 34 is in sliding contact with the one-way toothed disc 35, the outer side wall of the reciprocating turntable 25 is rotatably connected with a swing arm 31, a plurality of spray barrels 22 are provided at the bottom of the cleaning box 11, the inner side walls of the plurality of spray barrels 22 are slidably connected with push rods 23, the end of the push rod 23 is fixedly connected with a pressing plate 24, the pressing plate 24 is rotatably connected with the other end of the swing arm 31, and the top of the cleaning box 11 is fixedly connected with a storage box 20; When the cleaning box 11 moves unidirectionally and the lubricant is applied to the surface of the coil, the cleaning box 11 will move to the right under the rotation of the reciprocating screw 9. When the cleaning box 11 moves to the right, the roller 14 will rotate in the opposite direction under the contact with the slide rail 12. When the roller 14 rotates in the opposite direction, in addition to driving the stirring rod 26 to stir the lubricant in the storage box 20 through the pulley 30 mentioned above, it will also cause the one-way toothed disc 35 at the end of the driving rod 28 to rotate in the opposite direction. When the one-way toothed disc 35 rotates in the opposite direction, the end of the one-way baffle plate 34 will abut against the right-angled edge of the one-way toothed disc 35, thereby driving the reciprocating turntable 25 to rotate. When the reciprocating turntable 25 rotates, it will drive the pressure plate 24 to reciprocate up and down to squeeze the push rod 23 through the action of the swing arm 31, so that the push rod 23 performs a reciprocating suction movement up and down in the spray barrel 22; A pluggable feeding port 21 is provided on the top of the material storage box 20, and a plurality of conveying pipes 36 are connected to the bottom of the material storage box 20, and the other ends of the plurality of conveying pipes 36 are respectively connected to the interior of a plurality of spray barrels 22. A stirring rod 26 is rotatably connected to the inner wall of the material storage box 20, and a plurality of stirring shafts 27 are fixedly connected to the outer wall of the stirring rod 26. A pulley 30 is fixedly connected to the end of the stirring rod 26, and a transmission belt 29 is sleeved on the outer wall of the pulley 30. The end of the transmission belt 29 away from the pulley 30 is sleeved on the outer wall of the driving rod 28. The winding mechanism is arranged at the rear of the coating mechanism. After the coil is processed, the coil is stamped. The coating mechanism includes a plurality of winding rollers 6 arranged on the side of the conveying member 4, and a punch 5 is arranged on the side of the winding roller 6. When the push rod 23 performs reciprocating suction motion in the spray barrel 22, the evenly stirred lubricant in the storage box 20 will be sucked into the spray barrel 22 through the conveying pipe 36 and sprayed onto the surface of the coil. When the spray barrel 22 is moving to the right and spraying the lubricant onto the surface of the coil, the operator can control the upper and lower electric rods 19 to extend downward so that the smoothing scraper 18 contacts the surface of the coil, and the lubricant sprayed from multiple spray barrels 22 is evenly smoothed. When the lubricant is evenly applied to both sides of the coil, the sensor located in the equipment body 1 will start the clamping roller 7 in the conveying member 4 to convey the coated section of the coil to the winding drum 6, which will be wound and formed by the winding drum 6, and finally conveyed to the punch 5 for stamping and forming to form a seamless bushing (this is the prior art and will not be elaborated on in detail), and the conveying member 4 will continue to convey the next section of the coil, repeat the above steps, and clean and apply lubricant to the coil.

[0019] In summary, a method for using a slotted bushing preparation device is also proposed, using the above-mentioned device, the method comprises the following steps: S1, the winding roller 2 will rotate to convey the prepared coiled material into the discharge box 3, and after being conveyed by the discharge box 3, the coiled material will enter the conveying member 4, and the cleaning mechanism will perform unidirectional cleaning on the surface of the coiled material; S2, after the coil is cleaned in one direction by the cleaning mechanism, the coating mechanism will move in the opposite direction to apply lubricant to the surface of the coil; S3, when the lubricant is evenly applied on both sides of the coil, the sensor located in the equipment body 1 will convey the section of the coil after the application to the winding mechanism through the conveying member 4 for stamping and forming to form a seamless bushing.

[0020] It should be noted that when the cleaning box 11 moves to the left and only cleans the surface of the coil, the one-way toothed disc 35 will rotate forwardly under the drive of the driving rod 28. When the one-way toothed disc 35 rotates forwardly, the one-way baffle 34 will continuously slide in contact with the bevel of the one-way toothed disc 35 under the pressure of the pressing spring 33, and will not drive the reciprocating turntable 25 to rotate. When the reciprocating turntable 25 no longer rotates, the multiple spray guns 22 will not spray lubricant downward without the driving force, thereby realizing the technology of the cleaning box 11 first cleaning the surface of the coil in one direction and then applying the lubricant to ensure the lubrication effect.

[0021] It should be noted that when the cleaning box 11 moves to the left and the cleaning scraper 16 scrapes and cleans the surface of the coil, the smoothing scraper 18 is retracted in the cleaning box 11 under the drive of the upper and lower electric rods 19. On the contrary, when the smoothing scraper 18 extends downward to apply lubricant, the cleaning scraper 16 is also retracted in the cleaning box 11 under the drive of the telescopic rod 17. When the smoothing scraper 18 is retracted into the cleaning box 11, the cleaning box 15 will clean the surface of the cleaning scraper 16 for the convenience of next use (this is the prior art and will not be elaborated in detail).

[0022] 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.
