Description

Technical Field

[0001] This invention relates to the field of rebar rolling mill technology, and in particular to a rebar preparation equipment and preparation method. Background Technology

[0002] A rebar rolling mill is a metallurgical equipment specifically designed for producing hot-rolled ribbed steel bars. It mainly works by continuously rolling steel billets through multiple passes to form specific thread ribs on the surface of the finished product, thereby enhancing the bond strength between the steel bars and concrete. It is widely used in construction, bridge and other engineering fields.

[0003] Existing technologies, such as the invention disclosed in CN110947756B, involve a rebar rolling mill device. The key technical points are as follows: it includes upper and lower mounting bases, each equipped with multiple rolls. The rolls on the upper and lower mounting bases correspond one-to-one to form roll pairs. The rolled material passes between the two rolls of each roll pair. A cooling ring seat and a heat-insulating ring seat are fixed between the upper and lower mounting bases between each pair of adjacent roll pairs. The cooling ring seat has a spray pipe inside. A water pump is installed on the top of the upper mounting base corresponding to the spray pipe. The spray pipe is connected to the water pump via a pipeline. An air passage is located on the top of the cooling ring seat between adjacent spray pipes. A fan is installed at one end of the air passage, and the other end is connected to a steam tower on the top of the upper mounting base via a first air pipe. The inner wall of the heat-insulating ring seat has multiple air holes, and a steam channel is located inside the heat-insulating ring seat. The steam channel is connected to each air hole and is also connected to the steam tower via a second air pipe. This design saves resources and provides good temperature control.

[0004] Regarding the above-mentioned issues, the following technical defects were found: In the existing threaded steel rolling mill, the slotted rolls are often difficult to keep stable when inserted into the frame, and the frictional resistance is large when rotating. In addition, the locking of the roll shaft usually relies on bolts or complex locking parts, and the installation and disassembly process is cumbersome and time-consuming, lacking a convenient structure for quick locking and manual unlocking. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rebar preparation device and method.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: It includes a frame, a grooving roller, a placement platform, and an installation assembly. A rotating shaft is rotatably connected to the inner wall of the frame, and one end of the rotating shaft is slidably inserted into the grooving roller. The placement platform is fixedly connected to one side of the frame. The installation assembly is located on the side of the grooving roller away from the rotating shaft. The grooving roller is installed inside the frame via the installation assembly. The installation assembly includes an installation ring, the arc surface of which has an annular groove. A plurality of rollers are rotatably connected to the inner wall of the annular groove. One end of the frame has a through hole, and the end of each roller away from the annular groove is slidably connected to the inner wall of the through hole. The inner wall of the installation ring has a plurality of grooves, and a conveyor belt and a plurality of conveyor shafts are disposed inside the grooves. Each of the conveyor shafts is rotatably connected to the inner wall of the groove. The inner wall of the conveyor belt is connected to the arc surfaces of several conveyor shafts. The arc surface of the grooving roller is in contact with the side of the conveyor belt away from the inner wall of the groove. A fixed frame is fixedly connected to one side of the frame. A slider is slidably connected to the inner wall of the fixed frame. A first spring is provided between the slider and the fixed frame. The two ends of the first spring are fixedly connected to the slider and one side of the fixed frame, respectively. An insert rod is fixedly connected to the other end of the slider. One end of the insert rod slides through to the periphery of the fixed frame. A fixed block is fixedly connected to one end of the grooving roller. The end of the insert rod away from the slider is slidably inserted into the fixed block. Slide grooves are provided at the upper and lower ends of the fixed frame. The slide grooves are connected to the interior of the fixed frame. An operating plate is fixedly connected to the upper and lower ends of the slider. The end of the operating plate away from the slider is slidably connected to the inner wall of the slide groove.

[0007] The above components achieve the following effects: the grooving roller is smoothly inserted into the frame by the assistance of the conveyor belt and conveyor shaft, the roller rotates in the annular groove to reduce the frictional resistance when the grooving roller rotates, and at the same time the first spring pushes the slider to insert the insertion rod into the fixed block to achieve quick locking of the grooving roller. The operation panel makes it easy to manually compress the spring to unlock, thereby simplifying the installation and disassembly process of the grooving roller.

[0008] Preferably, a guide shaft is fixedly connected to the inner wall of the fixed frame, a movable cavity is opened inside the insert rod, one end of the guide shaft is slidably inserted into the movable cavity, the slider is slidably connected to the arc surface of the guide shaft, and the first spring is sleeved on the periphery of the guide shaft.

[0009] The effect achieved by the above components is as follows: the sliding cavity of the insert rod is inserted through the guide shaft and the slider slides along the guide shaft, so that the slider maintains axial linear movement within the fixed frame, avoiding offset and jamming. At the same time, the first spring is sleeved on the periphery of the guide shaft, ensuring the stability of the spring during compression and rebound.

[0010] Preferably, the fixing frame has two fixing holes on the side away from the frame, and a pin is slidably inserted into one side of the slider, with the arc surface of the pin threadedly connected to the inner wall of the fixing hole.

[0011] The effect achieved by the above components is that by inserting the pin through the fixing hole and inserting the slider, the slider can be locked in a compressed state when the slotted roller is disassembled, so that the insert rod is kept away from the fixing block. There is no need to continuously manually press the operation panel, which makes it easy for a single person to complete the replacement operation.

[0012] Preferably, a positioning support is fixedly connected to one side of the frame, and the positioning support is slidably connected to the arc surface of the insertion rod.

[0013] The aforementioned components achieve the following effects: by sliding the positioning support with the arc surface of the insertion rod, they provide guidance and limit for the axial movement of the insertion rod, while enhancing the bending strength of the insertion rod and preventing deformation of the insertion rod due to external force collisions or vibrations.

[0014] Preferably, a dust collection assembly is provided at the lower end of the frame. The dust collection assembly includes a drive motor, the lower end of which is fixedly connected to the frame. A fan is fixedly connected to the output end of the drive motor. Several exhaust vents are provided on both sides of the frame. An installation groove is provided on the inner wall of the frame, located above the fan. A U-shaped frame is slidably connected to the inner wall of the installation groove. A filter screen is fixedly connected to the inner wall of the U-shaped frame. A support shaft is fixedly connected to the end of the U-shaped frame away from the filter screen. The end of the filter screen away from the inner wall of the U-shaped frame is sleeved around the support shaft.

[0015] The effects achieved by the above components are as follows: the drive motor drives the fan to rotate, forming an airflow inside the frame, which sucks in the debris generated by the grooving roller and collects it on the surface of the filter screen. The U-shaped frame can be pulled out as a whole for cleaning, and the support shaft enhances the structural strength of the filter screen edge.

[0016] Preferably, the inner wall of the frame is provided with a movable groove, the movable groove is located above the mounting groove, the inner wall of the movable groove is slidably connected to a movable rod, the arc surface of the movable rod is fixedly connected to a scraper and a pull rod, and the lower end of the scraper is in contact with the upper end of the filter screen.

[0017] The effect achieved by the above components is as follows: by pulling the lever, the moving rod drives the scraper to move along the surface of the filter screen, scraping off the debris attached to the filter screen and discharging it from the opening end of the U-shaped frame, thereby realizing online cleaning of the filter screen and avoiding debris blockage that affects the dust collection effect.

[0018] Preferably, a fixing pin is fixedly connected to the lower end of the frame, and a fixing plate and a threaded sleeve are provided on the arc surface of the fixing pin. The fixing plate is movably connected to the arc surface of the fixing pin, and the threaded sleeve is threadedly connected to the arc surface of the fixing pin. One side of the threaded sleeve is in contact with the fixing plate, and the side of the fixing plate away from the threaded sleeve is in contact with one side of the frame.

[0019] The effect achieved by the above components is as follows: by tightening the screw on the fixing pin, the fixing plate is pressed tightly against the side of the frame, thereby firmly confining the U-shaped frame and filter screen in the mounting groove, preventing the dust collection components from loosening due to equipment vibration, and facilitating disassembly and maintenance.

[0020] Preferably, a pressing assembly is provided at the upper end of the placement platform. The pressing assembly includes a pressing rod, the lower end of which is slidably inserted into the placement platform. A baffle is fixedly connected to the upper end of the pressing rod, and a pressure plate is fixedly connected to the arc surface of the pressing rod. A second spring is fixedly connected to the upper end of the pressure plate. The upper end of the second spring is fixedly connected to the inner wall of the placement platform. The second spring is sleeved around the periphery of the pressing rod. A connecting shaft is fixedly connected to the lower end of the pressing rod. Two conical blocks are rotatably connected to the arc surface of the connecting shaft, and the two conical blocks are arranged in a mirror image on both sides of the pressing rod.

[0021] The effect achieved by the above components is as follows: the pressure plate is pushed downward by the second spring, so that the pressure rod drives the connecting shaft and the conical block to press the threaded steel on the placement table. The spring force adapts to steel of different diameters, providing stable downward pressure and assisting the threaded steel to be conveyed forward.

[0022] Preferably, both ends of the connecting shaft are fixedly connected to rubber rings, the rubber rings have cavities inside, and the side of the conical block away from the pressure rod is in contact with the rubber ring.

[0023] The effect achieved by the above components is that the cavity inside the rubber ring provides elastic deformation space, allowing the two conical blocks to slide relative to each other on the connecting shaft. When encountering a wider threaded steel bar, the spacing can be adaptively adjusted to buffer the impact force and avoid rigid jamming or damage to the steel surface.

[0024] A method for preparing rebar manufacturing equipment includes the following steps:

[0025] S1. The grooving roller is pushed into the frame along the groove of the mounting ring through the transmission cooperation between the conveyor belt and the conveyor shaft, so that one end of the rotating shaft slides into the insertion end of the grooving roller, and the roller in the annular groove makes rolling contact with the inner wall of the through hole to reduce rotational friction.

[0026] S2. Continue to push the grooving roller until the fixed block at one end is aligned with the insertion rod. The first spring pushes the slider to slide along the guide shaft in the fixed frame, causing the insertion rod to pass through the positioning support and be inserted into the fixed block, thereby achieving axial locking of the grooving roller.

[0027] S3. When feeding, pull the baffle upward to make the pressure rod slide upward along the inner wall of the placement platform, which will drive the pressure plate to compress the second spring. The connecting shaft and the two mirror-arranged conical blocks will move upward accordingly, and the threaded steel will be placed under the two conical blocks.

[0028] S4. Release the baffle. The elastic force of the second spring pushes the pressure plate downward, causing the pressure rod and connecting shaft to drive the conical block to press the upper surface of the threaded steel. When the threaded steel is wide or the surface is uneven, the two conical blocks slide relative to each other on the connecting shaft, squeezing the cavity inside the rubber ring to produce elastic deformation, adaptively adjusting the spacing, achieving stable clamping of steel of different diameters, and reducing jumping during the feeding process.

[0029] S5. During the operation of the slotted roller, the fixed plate is tightened on the side of the frame by screwing the threaded sleeve onto the fixed pin, and the U-shaped frame and filter screen are fixed in the mounting groove. The drive motor is started to drive the fan to rotate, and the airflow generated by the fan is used to suck in the debris and attach it to the upper surface of the filter screen.

[0030] S6. When debris accumulates on the filter screen surface, pull the lever to make the moving rod slide along the moving groove, causing the lower end of the scraper to move close to the filter screen surface, scraping the debris from the opening end of the U-shaped frame into the external collection container, thus achieving online cleaning.

[0031] S7. When it is necessary to disassemble the grooving roller, move the operating plate along the slide to compress the first spring of the slider, drive the insert rod out of the fixed block, and then pass the pin through the fixed hole on the fixed frame and screw it into the slider to keep the slider locked.

[0032] S8. Pull out the grooving roller in the opposite direction. The roller and conveyor belt help the grooving roller to smoothly leave the frame, avoiding jamming between the rotating shaft and the inner hole of the grooving roller.

[0033] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0034] 1. In this invention, by setting up an installation component, the grooving roller is smoothly inserted into the frame by using a conveyor belt and a conveyor shaft. The roller rotates in the annular groove to reduce the frictional resistance when the grooving roller rotates. At the same time, the first spring pushes the slider to insert the insertion rod into the fixed block, thereby realizing the quick locking of the grooving roller. The operation panel facilitates manual compression of the spring to unlock, thus simplifying the installation and disassembly process of the grooving roller.

[0035] 2. In this invention, by setting up a dust collection component, the drive motor drives the fan to rotate, forming an airflow inside the frame, which sucks in the debris generated by the grooving roller grinding and collects it on the surface of the filter screen. The U-shaped frame can be pulled out as a whole for cleaning, and the support shaft enhances the structural strength of the filter screen edge.

[0036] 3. In this invention, by setting up a pressing assembly, the second spring pushes the pressing plate downward, so that the pressing rod drives the connecting shaft and the conical block to press the threaded steel on the placement table. The spring force adapts to steel of different diameters, providing stable downward pressure and assisting the threaded steel to be conveyed forward. Attached Figure Description

Detailed Implementation

[0046] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0047] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0048] Example 1, as Figure 1-2 As shown, the present invention provides a rebar preparation equipment and preparation method, including a frame 1, a grooving roller 3, a placement platform 7 and an installation component 4. A rotating shaft 2 is rotatably connected to the inner wall of the frame 1, and one end of the rotating shaft 2 is slidably inserted into the grooving roller 3. The placement platform 7 is fixedly connected to one side of the frame 1. The installation component 4 is located on the side of the grooving roller 3 away from the rotating shaft 2. The grooving roller 3 is installed inside the frame 1 through the installation component 4. A dust collection component 5 is provided at the lower end of the frame 1, and a pressing component 6 is provided at the upper end of the placement platform 7.

[0049] The following section will explain the specific settings and functions of its installation component 4, dust collection component 5, and material pressing component 6.

[0050] like Figures 3 to 5As shown, the mounting assembly 4 includes a mounting ring 401. An annular groove 402 is formed on the arc surface of the mounting ring 401. Several rollers 403 are rotatably connected to the inner wall of the annular groove 402. One end of the frame 1 has a through hole. The ends of the rollers 403 away from the annular groove 402 are slidably connected to the inner wall of the through hole. Several grooves 404 are formed on the inner wall of the mounting ring 401. A conveyor belt 406 and several conveyor shafts 405 are arranged inside the grooves 404. All conveyor shafts 405 are rotatably connected to the inner wall of the grooves 404. The inner wall of the conveyor belt 406 is connected to the arc surface of each of the conveyor shafts 405. The arc surface of the grooving roller 3 is in contact with the side of the conveyor belt 406 away from the inner wall of the groove 404. A fixing frame 407 is fixedly connected to one side of the frame 1. A slider 409 is slidably connected to the inner wall of the fixed frame 407. A first spring 408 is provided between the slider 409 and the fixed frame 407. The two ends of the first spring 408 are fixedly connected to one side of the slider 409 and the fixed frame 407, respectively. The other end of the slider 409 is fixedly connected to the insertion rod 410. One end of the insertion rod 410 slides through to the periphery of the fixed frame 407. One end of the slotted roller 3 is fixedly connected to the fixed block 411. The end of the insertion rod 410 away from the slider 409 is slidably inserted into the fixed block 411. The upper and lower ends of the fixed frame 407 are provided with sliding grooves 412. The sliding grooves 412 are connected to the interior of the fixed frame 407. The upper and lower ends of the slider 409 are fixedly connected to the operating plate 413. The end of the operating plate 413 away from the slider 409 is slidably connected to the inner wall of the sliding groove 412. The grooving roller 3 is smoothly inserted into the frame 1 via the conveyor belt 406 and the conveyor shaft 405. The roller 403 rotates within the annular groove 402 to reduce the frictional resistance during the rotation of the grooving roller 3. Simultaneously, the first spring 408 pushes the slider 409 to insert the insertion rod 410 into the fixing block 411, achieving quick locking of the grooving roller 3. The operating plate 413 facilitates manual compression of the spring to unlock, thus simplifying the installation and disassembly process of the grooving roller 3. A guide shaft 414 is fixedly connected to the inner wall of the fixed frame 407. A movable cavity 415 is opened inside the insertion rod 410. One end of the guide shaft 414 is slidably inserted into the movable cavity 415. The slider 409 is slidably connected to the arc surface of the guide shaft 414. The first spring 408 is sleeved around the guide shaft 414. The guide shaft 414 passes through the moving cavity 415 of the insert rod 410, and the slider 409 slides along the guide shaft 414, so that the slider 409 maintains axial linear movement within the fixed frame 407, avoiding offset and jamming. At the same time, the first spring 408 is sleeved around the guide shaft 414 to ensure the stability of the spring during compression and rebound. Two fixing holes 416 are opened on the side of the fixed frame 407 away from the frame 1. A pin 417 is slidably inserted into one side of the slider 409, and the arc surface of the pin 417 is threaded to the inner wall of the fixing hole 416.By inserting a pin 417 through a fixing hole 416 and into a slider 409, the slider 409 can be locked in a compressed state when disassembling the slotted roller 3, keeping the insert rod 410 detached from the fixing block 411. This eliminates the need for continuous manual pressing of the operating plate 413, facilitating replacement operations by a single person. A positioning support 418 is fixedly connected to one side of the frame 1, and the positioning support 418 is slidably connected to the arc surface of the insert rod 410. The sliding engagement between the positioning support 418 and the arc surface of the insert rod 410 provides guidance and limitation for the axial movement of the insert rod 410, while also enhancing the bending strength of the insert rod 410 and preventing deformation of the insert rod 410 due to external impacts or vibrations.

[0051] The entire installation assembly 4 achieves the following effect: the grooving roller 3 is smoothly inserted into the frame 1 by the conveyor belt 406 and the conveyor shaft 405. The roller 403 rotates in the annular groove 402 to reduce the frictional resistance when the grooving roller 3 rotates. At the same time, the first spring 408 pushes the slider 409 to insert the insertion rod 410 into the fixing block 411, thereby achieving quick locking of the grooving roller 3. The operation plate 413 facilitates manual compression of the spring to unlock, thus simplifying the installation and disassembly process of the grooving roller 3.

[0052] like Figure 6 and Figure 7As shown, the dust collection assembly 5 includes a drive motor 501, the lower end of which is fixedly connected to the frame 1. A fan 502 is fixedly connected to the output end of the drive motor 501. Several exhaust ports 503 are provided on both sides of the frame 1. An installation groove 504 is provided on the inner wall of the frame 1, located above the fan 502. A U-shaped frame 505 is slidably connected to the inner wall of the installation groove 504. A filter screen 506 is fixedly connected to the inner wall of the U-shaped frame 505. A support shaft 507 is fixedly connected to the end of the U-shaped frame 505 away from the filter screen 506. The end of the filter screen 506 away from the inner wall of the U-shaped frame 505 is fitted around the support shaft 507. The drive motor 501 drives the fan 502 to rotate, forming an airflow inside the frame 1. This airflow draws in the debris generated by the grooving roller 3 and collects it on the surface of the filter screen 506. The U-shaped frame 505 can be pulled out as a whole for cleaning, and the support shaft 507 enhances the structural strength of the edge of the filter screen 506. The inner wall of the frame 1 is provided with a movable groove 508, which is located above the mounting groove 504. A movable rod 509 is slidably connected to the inner wall of the movable groove 508. A scraper 510 and a pull rod 511 are fixedly connected to the arc surface of the movable rod 509. The lower end of the scraper 510 is in contact with the upper end of the filter screen 506. By pulling the pull rod 511, the movable rod 509 drives the scraper 510 to move along the surface of the filter screen 506, scraping off the debris attached to the filter screen 506 and discharging it from the opening end of the U-shaped frame 505, thereby realizing online cleaning of the filter screen 506 and avoiding debris blockage that affects the dust collection effect. A fixing pin 512 is fixedly connected to the lower end of the frame 1. A fixing plate 513 and a threaded sleeve 514 are provided on the arc surface of the fixing pin 512. The fixing plate 513 is movably connected to the arc surface of the fixing pin 512, and the threaded sleeve 514 is threadedly connected to the arc surface of the fixing pin 512. One side of the threaded sleeve 514 is in contact with the fixing plate 513, and the side of the fixing plate 513 away from the threaded sleeve 514 is in contact with one side of the frame 1. By tightening the threaded sleeve 514 on the fixing pin 512, the fixing plate 513 is pressed tightly against the side of the frame 1, thereby firmly confining the U-shaped frame 505 and the filter screen 506 within the mounting groove 504, preventing the dust collection assembly 5 from loosening due to equipment vibration, and facilitating disassembly and maintenance.

[0053] The entire dust collection assembly 5 achieves the following effect: by driving the fan 502 to rotate through the drive motor 501, an airflow is formed inside the frame 1, which sucks in the debris generated by the grooving roller 3 and collects it on the surface of the filter screen 506. The U-shaped frame 505 can be pulled out as a whole for cleaning, and the support shaft 507 enhances the structural strength of the edge of the filter screen 506.

[0054] like Figure 8As shown, the pressing assembly 6 includes a pressing rod 61. The lower end of the pressing rod 61 is slidably inserted into the placement platform 7. A baffle 62 is fixedly connected to the upper end of the pressing rod 61. A pressure plate 63 is fixedly connected to the arc surface of the pressing rod 61. A second spring 64 is fixedly connected to the upper end of the pressure plate 63. The upper end of the second spring 64 is fixedly connected to the inner wall of the placement platform 7. The second spring 64 is sleeved around the periphery of the pressing rod 61. A connecting shaft 65 is fixedly connected to the lower end of the pressing rod 61. Two conical blocks 66 are rotatably connected to the arc surface of the connecting shaft 65, and the two conical blocks 66 are arranged in a mirror image on both sides of the pressing rod 61. The second spring 64 pushes the pressure plate 63 downward, causing the pressing rod 61 to drive the connecting shaft 65 and the conical blocks 66 to press the threaded steel on the placement platform 7. The spring force adapts to steel of different diameters, providing stable downward pressure and assisting in the forward conveying of the threaded steel. Both ends of the connecting shaft 65 are fixedly connected to rubber rings 67. The rubber rings 67 have cavities inside, and the side of the conical block 66 away from the pressure rod 61 fits against the rubber ring 67. The cavity inside the rubber ring 67 provides elastic deformation space, allowing the two conical blocks 66 to slide relative to each other on the connecting shaft 65. When encountering a wide threaded steel bar, the spacing can be adaptively adjusted to buffer the impact force and avoid rigid jamming or damage to the steel surface.

[0055] The effect of the entire pressing assembly 6 is that the second spring 64 pushes the pressure plate 63 downward, so that the pressure rod 61 drives the connecting shaft 65 and the conical block 66 to press the threaded steel on the placement table 7. The spring force adapts to steel of different diameters, providing stable downward pressure and assisting the threaded steel to be conveyed forward.

[0056] The overall working principle is as follows: when the grooving roller 3 needs to be installed into the frame 1, the grooving roller 3 is first pushed into the groove 404 of the mounting ring 401 through the transmission cooperation between the conveyor belt 406 and the conveyor shaft 405. At the same time, one end of the rotating shaft 2 is slidably inserted into the insertion end of the grooving roller 3, and the roller 403 in the annular groove 402 rolls against the inner wall of the through hole to reduce rotational friction. Then, the grooving roller 3 is pushed until the fixing block 411 at one end is aligned with the insertion rod 410. At this time, the first spring 408 pushes the slider 409 in the fixing frame 407, so that the slider 409 slides axially along the guide shaft 414, driving the insertion rod 410 to pass through the positioning support 418 and insert into the fixing block 411. The grooving roller 3 is axially locked, and the positioning support 418 provides guidance and anti-bending protection for the insertion rod 410. When the grooving roller 3 needs to be disassembled, the operating plate 413 is first moved along the slide 412 to compress the first spring 408 by the slider 409, which drives the insertion rod 410 to exit the fixing block 411. Then, the pin 417 is passed through the fixing hole 416 on the fixing frame 407 and screwed into the slider 409 to keep the slider 409 locked. Then, the grooving roller 3 is pulled out in the opposite direction. Finally, the roller 403 and the conveyor belt 406 help the grooving roller 3 to smoothly leave the frame 1. Thus, the grooving roller 3 can be quickly replaced without hammering or prying, and the rotation shaft 2 and the inner hole of the grooving roller 3 are prevented from getting stuck.

[0057] When it is necessary to collect and clean the metal shavings generated by the grooving roller 3 grinding, first tighten the threaded sleeve 514 on the fixing pin 512 to make the fixing plate 513 press tightly against the side of the frame 1, thereby fixing the U-shaped frame 505 and the filter screen 506 in the mounting groove 504 to prevent them from vibrating out. At the same time, the support shaft 507 supports the edge of the filter screen 506 to keep it flat. Then, start the drive motor 501 to drive the fan 502 to rotate. The airflow generated by the fan 502 will suck in the shavings and make them adhere to the upper surface of the filter screen 506. Next, when the shavings accumulate on the surface of the filter screen 506, pull the pull rod 511 to make the moving rod 509 slide along the moving groove 508, which will drive the lower end of the scraper 510 to move close to the surface of the filter screen 506, scraping the shavings from the open end of the U-shaped frame 505 into the external collection container. Finally, through repeated scraping and continuous ventilation, the shavings are cleaned and efficiently recycled online, avoiding the filter screen 506 from clogging and affecting the dust collection effect, while reducing downtime maintenance time.

[0058] When feeding rebar, first pull up the baffle 62, causing the pressure rod 61 to slide upward along the inner wall of the placement platform 7, which in turn drives the pressure plate 63 to compress the second spring 64. At the same time, the connecting shaft 65 and the two mirror-arranged conical blocks 66 move upward. Then, place the rebar under the two conical blocks 66, and release the baffle 62. The elastic force of the second spring 64 pushes the pressure plate 63 downward, causing the pressure rod 61 and the connecting shaft 65 to drive the conical blocks 66 to press against the upper surface of the rebar. Meanwhile, the second spring 64 is sleeved around the pressure rod 61 to maintain continuous pressure. Secondly, when the width of the rebar is large or the surface is uneven, the two conical blocks 66 slide relative to each other on the connecting shaft 65, squeezing the cavity inside the rubber ring 67 to produce elastic deformation, thereby adaptively adjusting the spacing and avoiding rigid jamming. Finally, the rubber ring 67 absorbs the impact, ensuring that the conical blocks 66 always fit against the surface of the rebar, achieving stable clamping of steel of different diameters, reducing vibration during feeding, and improving processing accuracy.

[0059] The present invention also provides a method for preparing a rebar preparation device, comprising the following steps:

[0060] S1. The grooving roller 3 is pushed into the frame 1 along the groove 404 of the mounting ring 401 through the transmission cooperation between the conveyor belt 406 and the conveyor shaft 405, so that one end of the rotating shaft 2 slides into the insertion end of the grooving roller 3, and the roller 403 in the annular groove 402 rolls in contact with the inner wall of the through hole to reduce rotational friction.

[0061] S2. Continue to push the grooving roller 3 until the fixing block 411 at one end is aligned with the insertion rod 410. The first spring 408 pushes the slider 409 to slide along the guide shaft 414 in the fixing frame 407, which drives the insertion rod 410 to pass through the positioning support 418 and then insert into the fixing block 411, thereby achieving axial locking of the grooving roller 3.

[0062] S3. When feeding, pull up the baffle 62 to make the pressure rod 61 slide upward along the inner wall of the placement platform 7, which drives the pressure plate 63 to compress the second spring 64. The connecting shaft 65 and the two mirror-arranged conical blocks 66 move upward accordingly, and place the threaded steel below the two conical blocks 66.

[0063] S4. Release baffle 62. The elastic force of the second spring 64 pushes the pressure plate 63 downward, causing the pressure rod 61 and the connecting shaft 65 to drive the conical block 66 to press the upper surface of the threaded steel. When the width of the threaded steel is large or the surface is uneven, the two conical blocks 66 slide relative to each other on the connecting shaft 65, squeezing the cavity inside the rubber ring 67 to produce elastic deformation, adaptively adjusting the spacing, realizing stable clamping of steel of different diameters, and reducing jumping during the feeding process.

[0064] S5. During the operation of the slotted roller 3, the fixed plate 513 is pressed against the side of the frame 1 by tightening the threaded sleeve 514 on the fixed pin 512, and the U-shaped frame 505 and the filter screen 506 are fixed in the mounting groove 504. The drive motor 501 is started to drive the fan 502 to rotate. The airflow generated by the fan 502 is used to suck in the debris and attach it to the upper surface of the filter screen 506.

[0065] S6. When debris accumulates on the surface of the filter screen 506, pull the lever 511 to make the moving rod 509 slide along the moving groove 508, which will cause the lower end of the scraper 510 to move close to the surface of the filter screen 506, scraping the debris from the opening end of the U-shaped frame 505 into the external collection container, thus realizing online cleaning.

[0066] S7. When it is necessary to disassemble the slotted roller 3, move the operating plate 413 along the slide 412 to compress the first spring 408 with the slider 409, drive the insert rod 410 out of the fixing block 411, and then pass the pin 417 through the fixing hole 416 on the fixing frame 407 and screw it into the slider 409 to keep the slider 409 locked.

[0067] S8. Pull out the grooving roller 3 in the opposite direction. The roller 403 and the conveyor belt 406 help the grooving roller 3 to smoothly leave the frame 1, so as to avoid the shaft 2 from getting stuck in the inner hole of the grooving roller 3.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
