Description

Technical Field

[0001] This invention relates to the field of auxiliary equipment for steel bar processing, specifically a magnetic suction-type automatic waste collection device for steel bar processing. Background Technology

[0002] Rebar processing is an indispensable basic process in construction, bridge building, and machinery manufacturing. It mainly includes various processing steps such as straightening, cutting, bending, welding, and bundling of rebar. During these processes, a large amount of rebar waste is inevitably generated due to operations such as cutting the raw rebar to length, bending and shaping, and removing waste. This waste includes short rebars, rebar ends, and fine iron filings generated during the cutting process. With the rapid development of the modern construction industry, the amount of rebar processed is increasing day by day, and the problem of waste disposal in processing workshops is gradually receiving attention. Traditional methods mostly involve manual cleaning or simple collection devices. However, with the popularization of automated processing production lines, higher requirements are placed on the efficiency and automation of waste collection. How to efficiently and cleanly recycle and utilize these metal wastes has become an important part of optimizing and upgrading rebar processing production lines. This is not only related to the control of production costs, but also directly affects the environmental quality of the workshop and the health and safety of workers.

[0003] However, traditional steel scrap collection devices mostly use ordinary collection boxes or simple magnetic suction mechanisms, which have many drawbacks in actual use. Ordinary collection boxes can only passively receive scrap, and cannot effectively collect scrap scattered around the equipment or stuck in the grid. They often require secondary manual cleaning, which increases the labor intensity of workers. Moreover, fine iron filings can easily spread into the air and cause environmental pollution. While existing magnetic suction mechanisms can attract scrap, they generally have the problem of difficulty in unloading. The attracted scrap is difficult to fall off the magnet automatically, and there is a lack of protective measures to prevent scrap from splashing. During the collection process, steel scrap ends can easily fly and injure people, posing a significant safety hazard. In addition, the grid at the top of the collection device is easily blocked by fine scrap, affecting the normal falling of subsequent scrap, resulting in a high equipment failure rate and increased maintenance costs. Summary of the Invention

[0004] The technical problems to be solved: Traditional steel scrap collection devices have problems such as difficulty in automatically unloading scrap, low cleaning efficiency, easy clogging, and lack of safety protection leading to the risk of splashing.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic magnetic waste collection device for steel bar processing, comprising: Collection bins, as the main containers for waste collection, are used to centrally collect processed metal waste. The top cover is fixedly installed on the top of the collection box, serving both sealing and support functions; A guide grille, embedded in the top of the top cover, is used to guide the steel scrap accurately into the collection box; A magnetic suction element is slidably disposed inside the collection box for automatically adsorbing steel scrap by magnetic force; A manual / automatic drive unit is disposed on the outer wall of the top cover and extends into the interior of the top cover to connect with the magnetic suction unit. It is used to drive the magnetic suction unit to slide back and forth inside the collection box to achieve material suction and unloading. A canopy, located on top of the roof, serves as overall support and protection; A blowing mechanism, which extends through the top of the canopy, is used to blow the waste material adsorbed on the guide grid into the collection box; The protective component is slidably mounted on the canopy poles of the roof to shield and protect against flying waste that could injure people. A drive mechanism, disposed on the outer wall of the canopy and connected to the protective component, is used to drive the protective component to slide to open or close the protection.

[0006] Furthermore, the guide grid consists of a frame and several grid strips, with inclined surfaces on both sides of the top of each grid strip for guiding the material to flow smoothly into the gap between two adjacent grid strips.

[0007] Furthermore, the magnetic attractor includes: A movable plate is slidably disposed inside the top cover; Several material discharge holes are formed through the top of the moving plate for waste material to fall. Several permanent magnets are embedded in the top of the movable plate to generate magnetic attraction. When the permanent magnet is aligned with the gap between two adjacent grid bars, it magnetically attracts the material.

[0008] Furthermore, the manual / automatic drive unit includes: A threaded rod rotatably passes through the top cover and is threadedly connected to the movable plate; A servo motor is fixedly mounted on the outer wall of the top cover; Two transmission wheels are respectively located at the output end of the servo motor and sleeved on the outer wall of the threaded rod. A transmission belt, which is closed and fitted between the two transmission pulleys, is used to transmit power; A handwheel, located at the end of the threaded rod, is used for manual operation.

[0009] Furthermore, the blowing mechanism includes: Servo motor two is installed at the top of the canopy; A support rod rotatably passes through the ceiling via a pivot. A guide frame is disposed at the top of the support rod; An air outlet frame, located at the top of the guide frame, is used for downward airflow cleaning.

[0010] Furthermore, the blowing mechanism also includes: A turntable is mounted on the output end of the second servo motor. A sliding shaft is eccentrically mounted on the turntable and slidably mounted in the guide frame, used to drive the air outlet frame to swing back and forth when the turntable rotates to adjust the blowing angle.

[0011] Furthermore, the protective component includes: Several sliding sleeves are slidably fitted onto the canopy rods of the ceiling; A protective plate is disposed between two adjacent sliding sleeves and moves synchronously with the sliding sleeves; A connecting sleeve is disposed on the outer wall of one of the protective plates.

[0012] Furthermore, the drive mechanism includes: A support plate is provided on the outer wall of the ceiling; Servo motor three is located on the top of the support plate, and its output end passes through the support plate; The second threaded rod is located on the output end of the third servo motor, and its thread passes through the connecting sleeve.

[0013] Furthermore, the inner wall of the top cover is provided with a limiting groove, and the outer wall of the movable plate is provided with a limiting strip that can slide in the limiting groove, which is used to limit the sliding stroke of the movable plate and prevent it from deflecting.

[0014] A method for automatic collection of rebar waste using magnetic attraction during rebar processing includes the following steps: S1. Before the device is started, the protective components are in the open state, and the waste generated during the steel bar processing falls into the collection box through the guide grid.

[0015] S2. The manual and automatic drive unit drives the moving plate to slide. When the permanent magnet is opposite to the gap between two adjacent grid bars, the magnetic force of the permanent magnet passes through the gap of the grid bars and attracts the steel scrap, thus attracting and fixing the scrap to the grid bars. S3. After a certain amount of waste is adsorbed, the manual and automatic drive unit continues to drive the moving plate to move laterally, the permanent magnet is retracted into the bottom of the grid bar, the gap between two adjacent grid bars is opened, and the waste falls into the collection box through the discharge hole under the action of gravity. S4. At the same time, the blowing mechanism is started, the servo motor drives the turntable to rotate, and the sliding shaft drives the air outlet frame to swing back and forth, blowing the small iron filings remaining on the grid strips into the collection box. S5. During the blowing and dropping process, the drive mechanism drives the protective components to close, and the protective plate descends to cover the side of the canopy, effectively preventing waste from splashing. S6. After the material is unloaded, the protective mechanism reopens, and the next cycle begins. Throughout the process, the operator can either automatically drive the moving plate via a servo motor or manually operate it via a handwheel, achieving a combination of manual and automatic control.

[0016] Compared with existing technologies, this magnetic suction-type automatic waste collection device for steel bar processing has the following advantages: I. This invention achieves automatic adsorption and unloading of steel reinforcement scrap by using a reciprocating sliding magnetic suction component in conjunction with a guide grid. When the magnetic suction component slides to the position where the permanent magnet and the grid gap are opposite, the magnetic force passes through the gap and firmly adsorbs the scrap, preventing it from scattering. When the magnetic suction component moves laterally, the permanent magnet moves away from the gap, and the scrap automatically falls into the collection box through the discharge hole under the action of gravity. This design cleverly solves the problem of scrap being difficult to detach in traditional magnetic suction devices, greatly reduces the labor intensity of workers, significantly improves the automation level of scrap collection, effectively avoids the safety risks caused by manual cleaning, and improves the cleanliness and production efficiency of the processing site.

[0017] Second, this invention, by incorporating a manual / automatic integrated drive component, endows the device with greater flexibility and reliability in power drive. This component can achieve automated reciprocating drive via a servo motor and transmission belt, meeting the high-efficiency requirements of continuous production line operation. It can also be manually operated via a handwheel, playing a role in equipment maintenance, power outages, or when fine adjustments are needed. This dual-drive mode greatly enriches the device's application scenarios, ensuring stable operation under various complex working conditions. It not only improves the equipment's fault tolerance but also provides operators with more user-friendly options, enhancing the device's practicality.

[0018] Third, this invention significantly improves the cleaning effect and safety performance of the device by setting up a blowing mechanism and a sliding protective component. The blowing mechanism uses a servo motor to drive the turntable and sliding shaft, causing the air outlet frame to swing back and forth, which can blow away small waste materials stuck in the gaps of the grid from all directions, effectively preventing grid blockage and ensuring the smooth flow of the collection channel. The protective component, driven by the drive mechanism, can automatically close during the material falling process, forming a physical barrier to effectively prevent steel scrap from splashing and injuring people. When not in operation, it can automatically open without affecting normal material feeding. This linkage design greatly improves the safety of equipment operation and improves the workshop working environment. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figure 1-6 As shown, the present invention provides a technical solution: an automatic magnetic waste collection device for steel bar processing. The device is placed next to the steel bar processing production line or under the cutting equipment to automatically collect short steel bars, steel bar ends, iron filings and other metal waste generated during the processing. It solves the problems of low efficiency of traditional manual cleaning, easy clogging of ordinary collection boxes 1 and difficulty in automatic unloading of magnetic devices. The core advantage of this device is that it realizes automatic adsorption and automatic unloading of waste through the cooperation of magnetic attraction and mechanical linkage. It is also equipped with a protective mechanism to prevent waste from splashing, which significantly improves production safety and on-site environmental quality. The collection device mainly includes a collection box 1, a top cover 2, a guide grid 3, a magnetic attraction component 4, a manual-automatic drive component 5, a canopy 6, a blowing mechanism 7, a protective component 8 and a drive mechanism 9.

[0023] The collection box 1 is a rectangular box structure with an open top, serving as the main container for waste collection, and its interior forms a space for holding waste. The top cover 2 is a rectangular cover structure, fixedly installed on the top of the collection box 1. The top of the top cover 2 has an opening for embedding the guide grille 3. The guide grille 3 is embedded in the top opening of the top cover 2 and consists of a frame and several grille strips. The grille strips are arranged at equal intervals along the length of the top cover 2. The top two sides of the grille strips have inclined surfaces for guiding the material to fall. The guide effect of the inclined surfaces guides the waste to the gap between two adjacent grille strips, which not only facilitates the sliding of waste, but also plays a certain role in gathering the waste when magnetically attracted.

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the magnetic suction component 4 is slidably disposed inside the collection box 1 and located below the top cover 2. It is the core component for realizing automatic waste collection and unloading. The magnetic suction component 4 includes a horizontally slidable movable plate 401 disposed inside the top cover 2. The top of the movable plate 401 is evenly provided with several discharge holes 402 for waste to pass through and fall into the collection box 1. The top of the movable plate 401 is also evenly embedded with several permanent magnets 403, and the permanent magnets 403 and the discharge holes 402 are arranged alternately. The inner wall of the top cover 2 is provided with a limiting groove 10, and the outer wall of the movable plate 401 is provided with a limiting groove 10. A limiting strip 11 that can slide in the limiting groove 10 is provided to limit the sliding stroke of the moving plate 401 and prevent it from deflecting, ensuring smooth movement. When the permanent magnet 403 is opposite to the gap between two adjacent grid bars, the magnetic force of the permanent magnet 403 passes through the gap of the grid bars to attract steel scrap and fix the scrap on the grid bars. When the moving plate 401 moves laterally, the permanent magnet 403 is retracted into the bottom of the grid bars, the gap between two adjacent grid bars is opened, and the scrap falls into the collection box 1 through the discharge hole 402 under the action of gravity, realizing the automatic switching of adsorption and unloading.

[0025] The manual / automatic drive unit 5 is located on the outer wall of the top cover 2 and is used to drive the magnetic suction unit 4 to slide back and forth inside the collection box 1. The manual / automatic drive unit 5 includes a horizontally arranged threaded rod 501, which rotatably passes through the side wall of the top cover 2 through a bearing and is threadedly connected to the moving plate 401. A servo motor 502 is fixedly installed on the outer wall of the top cover 2. Two transmission wheels 503 are respectively fixedly installed at the output end of the servo motor 502 and sleeved on the outer wall of the threaded rod 501. A transmission belt 504 is closedly sleeved between the two transmission wheels 503 for transmitting power. A handwheel 505 is also provided at the end of the threaded rod 501. The servo motor 502 drives the threaded rod 501 to rotate through the transmission wheels 503 and the transmission belt 504. The threaded rod 501 drives the moving plate 401 to slide back and forth inside the top cover 2. The operator can also manually rotate the handwheel 505 to drive the threaded rod 501 to rotate, so as to realize manual operation and meet the needs of different working conditions.

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the canopy 6 is a frame structure located on top of the top cover 2, composed of multiple canopy rods for installing the blowing mechanism 7 and protective components 8. The blowing mechanism 7 extends through the top of the canopy 6 and blows residual waste adsorbed on the guide grid 3 into the collection box 1, preventing fine iron filings from clogging the grid gaps. The blowing mechanism 7 includes a servo motor 701 fixedly mounted on the top of the canopy 6; a vertically mounted support rod 702 rotatably extends through the canopy 6 via a pivot; a guide frame 703 is fixedly mounted on the top of the support rod 702; and an air outlet frame 704 is fixedly mounted on the top of the guide frame 703. 04 is a tubular structure with several air outlets at its bottom for downward airflow. The air outlet frame 704 is connected to an external air source. A turntable 705 is fixedly mounted on the output end of the servo motor 701. A sliding shaft 706 is eccentrically fixed on the turntable 705. The upper end of the sliding shaft 706 is slidably mounted in the guide frame 703. The servo motor 701 drives the turntable 705 to rotate, and the eccentrically mounted sliding shaft 706 slides back and forth in the guide frame 703, causing the guide frame 703 and the air outlet frame 704 to swing back and forth around the axis of the support rod 702, thereby adjusting the blowing angle, expanding the cleaning range, and effectively blowing off residual waste.

[0027] The protective component 8 is slidably installed on the canopy rod of the ceiling 6 to shield and protect against splashing of waste materials. The protective component 8 includes several sliding sleeves 801 that are slidably fitted onto the canopy rod of the ceiling 6. A protective plate 802 is fixedly installed between two adjacent sliding sleeves 801. A connecting sleeve 803 is fixedly installed on the outer wall of one of the protective plates 802.

[0028] The drive mechanism 9 is located on the outer wall of the canopy 6 and connected to the protective component 8. It is used to drive the protective component 8 to slide to open or close the protection. The drive mechanism 9 includes a support plate 901 fixedly installed on the outer wall of the canopy 6. A servo motor 902 is fixedly installed on the top of the support plate 901, and its output end passes through the support plate 901. A threaded rod 903 is vertically installed on the output end of the servo motor 902. The threaded rod 903 is threaded through the connecting sleeve 803. The servo motor 902 drives the threaded rod 903 to rotate. The threaded rod 903 drives the protective plate 802 and the sliding sleeve 801 to slide up and down along the canopy rod through the connecting sleeve 803, thereby opening and closing the protective plate 802. Before the device is started, the protective component 8 is in the open state, which is convenient for the operator to observe and operate. During the blowing and dropping process, the drive mechanism 9 drives the protective component 8 to close, and the protective plate 802 descends to cover the side of the canopy 6, effectively preventing waste from splashing. After the dropping is completed, the protective component 8 reopens.

[0029] Working process: Before the device is started, the drive mechanism 9 works, and the servo motor 3 902 drives the threaded rod 2 903 to rotate. The threaded rod 2 903, through the threaded engagement with the connecting sleeve 803, drives the protective plate 802 and the sliding sleeve 801 to slide up the roof rod of the ceiling 6, so that the protective part 8 is in the open state, which is convenient for the operator to observe and operate. During the steel bar processing, the waste materials such as short steel bars, steel bar ends, iron filings and other waste materials generated fall on the top of the device. The guide grid 3 uses the inclined surface at the top of its grid bars to guide the waste materials to the gap between two adjacent grid bars.

[0030] Subsequently, the manual / automatic drive unit 5 is activated, and the servo motor 502 drives the threaded rod 501 to rotate through the transmission wheel 503 and the transmission belt 504. The threaded rod 501 drives the moving plate 401 to slide along the inside of the top cover 2. At this time, the limiting strip 11 slides in the limiting groove 10, limiting the sliding stroke of the moving plate 401 and preventing it from deflecting. When the moving plate 401 slides to the point where the permanent magnet 403 embedded at its top is opposite to the gap between two adjacent grid strips, the magnetic force of the permanent magnet 403 passes through the gap of the grid strip and adsorbs and fixes the steel scrap onto the grid strip, completing the magnetic suction process.

[0031] After a certain amount of waste is adsorbed, the manual / automatic drive unit 5 continues to drive the moving plate 401 to move laterally, so that the permanent magnet 403 is retracted into the bottom of the grid strip. At this time, the gap between two adjacent grid strips is opened, the waste loses magnetic adsorption, and under the action of gravity, it passes through the dropping hole 402 opened on the moving plate 401 and falls into the collection box 1, realizing automatic unloading.

[0032] At the same time, the blowing mechanism 7 is started, and the servo motor 701 drives the turntable 705 to rotate. The sliding shaft 706, which is eccentrically set on the turntable 705, slides back and forth in the guide frame 703, causing the guide frame 703 and the air outlet frame 704 to swing back and forth around the rotation axis of the support rod 702, thereby adjusting the blowing angle of the air outlet frame 704 and blowing the small iron filings remaining on the grid strips into the collection box 1 to prevent blockage.

[0033] During the blowing and unloading process, the drive mechanism 9 drives the protective component 8 to close, and the servo motor 902 reverses to drive the threaded rod 903 to rotate, driving the protective plate 802 and the sliding sleeve 801 to slide down. The protective plate 802 covers the side of the canopy 6, effectively preventing waste from splashing, protecting the operator's safety and avoiding environmental pollution. After the unloading is completed, the protective component 8 reopens and enters the next cycle. Throughout the process, the operator can not only automatically drive the moving plate 401 to slide using the servo motor 502, but also manually drive the threaded rod 501 to rotate by rotating the handwheel 505 when needed, achieving manual and automatic control.

[0034] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
