Description

Technical Field

[0001] This utility model relates to the field of steel rolling pickling technology, specifically to a pickling disc shearing device to prevent wire breakage. Background Technology

[0002] Pickling and rolling disc shears are essential equipment in cold rolling processes, widely used in sheet and strip production. Their main function is to trim the longitudinal edges of moving sheet and strip steel to the required nominal width, ensuring neat edges, precise width, and no burrs, thus guaranteeing product width tolerances and edge quality. Due to their advantages of continuous online operation, high nominal dimensional accuracy, and high edge quality, they are widely used in edge shearing on cold-rolled strip steel production lines.

[0003] In the production operation of pickling and rolling disc shears, the stable transmission and handling of edge wires is a key link to ensure production efficiency and product quality. However, traditional edge wire handling devices have revealed many problems in practical applications, which seriously restrict the smooth progress of production. Utility Model Content

[0004] This invention proposes a device to prevent wire breakage during the shearing of acid-rolled discs, which solves the problem of wire breakage that easily occurs during the shearing of acid-rolled discs in related technologies.

[0005] The technical solution of this utility model is as follows:

[0006] A device for preventing wire breakage during pickling and rolling disc shearing includes:

[0007] frame;

[0008] The limiting roller is rotatable and movable relative to the frame. There are several limiting rollers, and two limiting rollers form a group. A limiting space is formed between the two limiting rollers in a group. The limiting space is used for the passage of edge threads.

[0009] A reversing roller is rotatably mounted on the frame and is perpendicular to the axial direction of the limiting roller, and is located on one side of the limiting roller.

[0010] As a further technical solution, it also includes:

[0011] A movable component is movably mounted on the frame. There are several movable components, and the two ends of a set of limiting rollers are respectively rotatably mounted on two of the movable components.

[0012] As a further technical solution, the limiting roller is rotatable and movable relative to the moving member, and further includes:

[0013] An adjusting member is movably disposed on the moving member. There are several adjusting members, and at least two adjusting members are movably disposed on one of the moving members. The end of the limiting roller is rotatably disposed on the adjusting member.

[0014] As a further technical solution, the movable component has a first threaded hole, the adjusting component has a second threaded hole, and the component further includes:

[0015] The first adjusting screw has a first threaded portion and a second threaded portion. The first threaded portion and the second threaded portion have opposite directions and are located at both ends of the first adjusting screw. The first threaded portion and the second threaded portion of the first adjusting screw are respectively threaded into the first threaded holes of the two moving parts.

[0016] The second adjusting screw has a third threaded portion and a fourth threaded portion, the third threaded portion and the fourth threaded portion having opposite directions and being located at both ends of the second adjusting screw, and the third threaded portion and the fourth threaded portion of one second adjusting screw are respectively threaded into the second threaded holes of two adjacent adjusting members.

[0017] As a further technical solution, it also includes:

[0018] Wear-resistant sleeves are disposed on the limiting roller and the reversing roller.

[0019] As a further technical solution, the wear-resistant sleeve includes:

[0020] The first set of bodies is disposed on the limiting roller and the reversing roller, and there are several of them arranged in sequence. The first set of bodies has a first connecting part and a first connecting groove. After the first connecting part is inserted into the first connecting groove of another adjacent first set of bodies, the two adjacent first sets of bodies are connected.

[0021] The second set is disposed on the limiting roller and the reversing roller, and there are several of them arranged in sequence. The second set has a second connecting part and a second connecting groove. After the second connecting part is inserted into the second connecting groove of another adjacent second set, the two adjacent second sets are connected. The outer surfaces of the first set and the second set form a columnar wear-resistant surface.

[0022] As a further technical solution, both the outermost first sleeve and the second sleeve have a connecting end, which is used to connect the first sleeve and the second sleeve.

[0023] As a further technical solution, it also includes:

[0024] A winding machine, located on one side of the frame, is used for collecting the edge yarn.

[0025] As a further technical solution, it also includes:

[0026] A fastening bolt, which passes through the connecting end, is used to fix the first sleeve and the second sleeve.

[0027] As a further technical solution, both the first and second sets of bodies have cast iron layers and wear-resistant layers arranged from the inside out.

[0028] The working principle and beneficial effects of this utility model are as follows:

[0029] The limiting rollers are rotatable and movable relative to the frame, a design that provides adjustment capability. Multiple limiting rollers are arranged in pairs, with a limiting space formed between the two rollers in each pair, through which the edge wire passes. The rotatable limiting rollers reduce friction as the edge wire passes, preventing wear or even breakage due to excessive friction. Simultaneously, the movable design allows the size of the limiting space to be adjusted according to the actual width of the edge wire, ensuring accurate limiting of edge wires of different specifications and guaranteeing stability during transmission.

[0030] The limiting roller plays a crucial guiding role for the edge wire. During the operation of the pickling and rolling disc shear, the direction of the edge wire needs to be precisely controlled to prevent problems such as deviation and entanglement, thereby reducing the risk of wire breakage. The limiting roller confines the edge wire to a specific path through a limiting space, allowing it to be smoothly transmitted to subsequent processing stages. After the edge wire is cut off by the disc shear, the limiting roller can quickly guide the edge wire into the correct transmission track, preventing the edge wire from swinging randomly in the air and reducing the risk of edge wire breakage.

[0031] The reversing roller is rotatably mounted on the frame and perpendicular to the limiting roller. This vertical arrangement allows the reversing roller to effectively change the transmission direction of the edge yarn. In actual production, the edge yarn transmission path may need to be adjusted according to the equipment layout and process flow; the reversing roller meets this requirement. By rotating itself, it changes the edge yarn from its original horizontal or vertical direction to the desired direction, ensuring that the edge yarn can smoothly enter the next processing equipment, improving the flexibility and adaptability of the production system.

[0032] During the process of changing the direction of the edge wire, the reversing roller can also alleviate the edge wire tension. When the edge wire passes around the reversing roller, its tension is dispersed and adjusted to a certain extent. This helps prevent wire breakage caused by excessive edge wire tension. For example, when the edge wire is transferred from one high-speed rotating component to another component with a different speed, the reversing roller can smoothly transition the edge wire tension through its own rotation and contact, ensuring that the edge wire is subjected to uniform force throughout the transmission process, and improving the stability and reliability of edge wire transmission.

[0044] Reference Figures 1-5 This is the first embodiment of the present invention, which proposes a device for preventing edge breakage of acid-rolled disc shearing. It includes a frame 1, a limiting roller 2 that is rotatable and movable relative to the frame 1, and several limiting rollers 2. Two limiting rollers 2 form a group, and a limiting space 201 is formed between the two limiting rollers 2 in a group. The limiting space 201 is used for the passage of edge wire. A reversing roller 3 is rotatably mounted on the frame 1 and is arranged perpendicular to the axis of the limiting roller 2 and located on one side of the limiting roller 2.

[0045] In this embodiment, the frame 1 serves as the basic structure of the entire device, providing a stable mounting platform for the limiting roller 2 and the reversing roller 3. It bears the weight of each component and the various forces generated during operation, ensuring that the device does not shift or shake during operation. For example, when the pickling disc shear vibrates at high speed, the robust frame 1 remains stable, allowing the limiting roller 2 and the reversing roller 3 to operate normally, preventing abnormal edge wire processing due to frame instability.

[0046] The limiting rollers 2 are rotatable and movable relative to the frame 1, a design that provides them with adjustment capabilities. Multiple limiting rollers 2 are arranged in pairs, with a limiting space 201 formed between the two rollers in each pair, through which the edge wire passes. The rotatable limiting rollers 2 reduce friction during edge wire passage, preventing wear or even breakage due to excessive friction. Simultaneously, the movable nature of the limiting space 201 allows adjustment of its size according to the actual width of the edge wire, ensuring accurate limiting of edge wires of different specifications and guaranteeing stability during transmission.

[0047] The limiting roller 2 provides excellent guidance for the edge wire. During the operation of the pickling and rolling disc shear, the direction of the edge wire needs to be precisely controlled to prevent problems such as deviation and entanglement, thereby reducing the risk of wire breakage. The limiting roller 2, through the limiting space 201, confines the edge wire to a specific path, allowing it to be smoothly transmitted to the subsequent processing stage. After the edge wire is cut off by the disc shear, the limiting roller 2 can quickly guide the edge wire into the correct transmission track, preventing the edge wire from swinging randomly in the air and reducing the risk of edge wire breakage.

[0048] The reversing roller 3 is rotatably mounted on the frame 1 and is perpendicular to the limiting roller 2. This vertical arrangement allows the reversing roller 3 to effectively change the transmission direction of the edge yarn. In actual production, the edge yarn transmission path may need to be adjusted according to the equipment layout and process flow; the reversing roller 3 meets this requirement. By rotating itself, it changes the edge yarn from its original horizontal or vertical direction to the desired direction, ensuring that the edge yarn can smoothly enter the next processing equipment, thus improving the flexibility and adaptability of the production system.

[0049] During the process of the edge wire changing direction, the reversing roller 3 can also alleviate the edge wire tension. When the edge wire passes around the reversing roller 3, its tension will be dispersed and adjusted to a certain extent. This helps to prevent wire breakage caused by excessive edge wire tension. For example, when the edge wire is transferred from one high-speed rotating component to another component with a different speed, the reversing roller 3 can smoothly transition the tension of the edge wire through its own rotation and contact, ensuring that the edge wire is subjected to uniform force throughout the entire transmission process, and improving the stability and reliability of edge wire transmission.

[0050] Furthermore, it also includes a movable component 4, which is movably mounted on the frame 1. There are several movable components 4, and the two ends of a set of limiting rollers 2 are respectively rotatably mounted on two movable components 4.

[0051] In this embodiment, the movable component 4 is movably mounted on the frame 1, and the two ends of a set of limiting rollers 2 are respectively rotatably mounted on the two movable components 4. This structure allows the operator to easily adjust the distance between the set of limiting rollers 2 by moving the movable component 4, thereby flexibly changing the size of the limiting space 201. In actual production, the pickling and rolling disc shear may handle various edge wires of different widths. In this way, the device can easily adapt to various edge wire specifications, ensuring that the edge wires are accurately limited within the limiting space 201. For example, when different thickness plates are switched on the production line, resulting in edge wires of different widths, the operator only needs to move the movable component 4 to quickly adjust the limiting space 201 to meet the limiting requirements of the new edge wire width, avoiding edge wire deviation or breakage due to an unsuitable limiting space.

[0052] Precisely adjusting the size of the limiting space 201 according to the actual condition of the edge wire helps improve the stability of edge wire transmission. A suitable limiting space can tightly fit both sides of the edge wire, providing sufficient support and guidance, and reducing swaying and deviation during transmission. For narrower edge wires, reducing the limiting space can better constrain the edge wire and prevent it from swaying left and right during transmission; while for wider edge wires, increasing the limiting space can avoid squeezing damage caused by insufficient space, thereby reducing the risk of edge wire breakage and ensuring production continuity.

[0053] Since the two ends of the limiting roller 2 are rotatably mounted on the movable part 4, when the limiting roller 2 experiences wear, malfunction, or requires regular maintenance, the operator can move the limiting roller 2 to a more convenient position by moving the movable part 4. This greatly simplifies the disassembly, installation, and maintenance process of the limiting roller 2, saving maintenance time and labor costs. For example, when replacing the limiting roller 2, simply moving the movable part 4 to the appropriate position allows for easy removal of the limiting roller 2 without requiring large-scale disassembly of the entire device, thus improving the maintainability of the equipment.

[0054] The movable component 4 allows for flexible adjustment of the position of the entire limiting roller assembly on the frame 1. During equipment installation and commissioning, or when changes in the production process require fine-tuning of the edge wire transmission path, operators can quickly adjust the position and angle of the limiting roller 2 by moving the movable component 4 to adapt to new production requirements. This ease of overall adjustment helps improve the adaptability and production efficiency of the equipment, enabling the pickling disc shearing edge wire breakage prevention device to better meet the needs of different production scenarios.

[0055] Furthermore, the limiting roller 2 is rotatable and movable relative to the moving part 4, and also includes an adjusting part 5. The adjusting part 5 is movablely disposed on the moving part 4. There are several adjusting parts 5, and at least two adjusting parts 5 are movablely disposed on one moving part 4. The end of the limiting roller 2 is rotatably disposed on the adjusting part 5.

[0056] In this embodiment, the adjusting member 5 is movably mounted on the moving member 4, and there are at least two adjusting members 5 on each moving member 4. The end of the limiting roller 2 is rotatably mounted on the adjusting member 5. This makes the position adjustment of the limiting roller 2 more precise. By adjusting the position of the adjusting member 5 on the moving member 4, fine-tuning of the position of the limiting roller 2 can be achieved.

[0057] When processing edge threads of varying widths and thicknesses, the position of the limiting roller 2 can be adjusted over a wide range using the moving part 4, and local fine-tuning can also be performed using the adjusting part 5. For production scenarios requiring high precision in edge thread processing, such as processing high-precision thin plate edge threads, this fine-tuning capability ensures that the limiting roller 2 is more accurately aligned with the edge thread, confining it to the ideal transmission path, reducing the risk of edge thread deviation, and improving the stability and quality of edge thread processing.

[0058] Since each moving part 4 is equipped with multiple adjusting parts 5, when different adjusting parts 5 are in different positions on the moving part 4, the relative positional relationship between two limiting rollers 2 within the same set of limiting rollers 2 can be changed. This allows for more precise adjustment of the shape and size of the limiting space 201, rather than simply expanding or shrinking the whole.

[0059] For some non-standard shapes or uneven widths of edge wires, by adjusting the position of the adjusting component 5, the limiting space 201 can better fit the shape of the edge wire, avoiding uneven force or wire breakage caused by the mismatch between the limiting space and the edge wire shape, and improving the adaptability of the device to edge wires of different shapes.

[0060] The mobility of the adjusting component 5 allows the position and angle of the limiting roller 2 to be dynamically adjusted according to the actual transmission of the edge wire during the edge wire transmission process. When the edge wire experiences local deviation or tension change during transmission, the adjusting component 5 can be adjusted in a timely manner to allow the limiting roller 2 to better guide the edge wire.

[0061] Under different production conditions, such as changes in equipment speed and tension, the adjusting component 5 can help adjust the setting of the limiting roller 2 to adapt to the new conditions. For example, when the running speed of the pickling disc shear increases, the tension and transmission characteristics of the edge wire may change. By adjusting the adjusting component 5, the layout of the limiting roller 2 can be optimized to ensure that the edge wire can still be stably transmitted within the limiting space 201 under high-speed conditions, preventing edge wire handling problems caused by changes in working conditions.

[0062] When maintenance, replacement, or inspection of the limit roller 2 is required, the presence of the adjusting element 5 makes operation more convenient. The operator can adjust the adjusting element 5 to move the limit roller 2 to a more easily operable position without disassembling the entire device or the moving part 4.

[0063] Adjustment component 5 provides operators with more operational options, allowing for more flexible setting of the position and angle of the limit roller 2 during initial installation, commissioning, or process adjustments. Operators can fine-tune the limit roller 2 using adjustment component 5 based on experience and actual production needs, enabling the device to reach its optimal working state, thus improving the operational flexibility of the equipment and the operator's experience.

[0064] Furthermore, the moving part 4 has a first threaded hole 401, the adjusting part 5 has a second threaded hole 501, and also includes a first adjusting screw 6. The first adjusting screw 6 has a first threaded portion 601 and a second threaded portion 602. The first threaded portion 601 and the second threaded portion 602 have opposite threads and are located at both ends of the first adjusting screw 6. The first threaded portion 601 and the second threaded portion 602 of the first adjusting screw 6 are respectively threaded into the first threaded holes 401 of the two moving parts 4. The second adjusting screw 7 has a third threaded portion 701 and a fourth threaded portion 702. The third threaded portion 701 and the fourth threaded portion 702 have opposite threads and are located at both ends of the second adjusting screw 7. The third threaded portion 701 and the fourth threaded portion 702 of one second adjusting screw 7 are respectively threaded into the second threaded holes 501 of the two adjusting parts 5.

[0065] In this embodiment, the first adjusting screw 6 has a first threaded portion 601 and a second threaded portion 602 with opposite screw directions at both ends, and they are respectively threaded into the first threaded holes 401 of the two moving parts 4. When the first adjusting screw 6 is rotated, the two moving parts 4 will move towards or away from each other simultaneously due to the opposite screw directions.

[0066] This design allows the moving parts 4 at both ends of a set of limiting rollers 2 to adjust their positions synchronously, thereby precisely changing the width of the limiting space 201. For example, when processing edge wires of different widths, simply rotating the first adjusting screw 6 can quickly and accurately adjust the limiting space 201, ensuring that the edge wire remains in a stable limiting state during transmission and preventing edge wire deviation or breakage due to an unsuitable limiting space. The second adjusting screw 7 also has a third threaded portion 701 and a fourth threaded portion 702 with opposite screw directions, which are threadedly connected to the second threaded holes 501 of the two adjusting parts 5, respectively. When the second adjusting screw 7 is rotated, the two adjusting parts 5 move synchronously and relative to each other, thereby achieving fine adjustment of the position of the ends of the limiting rollers 2.

[0067] This fine-tuning function is crucial for optimizing the angle and position of the limiting roller 2. When handling processes with extremely high requirements for edge wire transmission accuracy, the position of the limiting roller 2 can be finely adjusted by rotating the second adjusting screw 7, allowing the limiting roller 2 to better conform to the movement trajectory of the edge wire, further improving the stability and accuracy of edge wire transmission, and effectively reducing the risk of edge wire breakage.

[0068] The positions of the moving part 4 and the adjusting part 5 are adjusted by rotating the first adjusting screw 6 and the second adjusting screw 7, making the operation simple and intuitive. Compared with the traditional manual adjustment method, this screw adjustment method greatly improves the operating efficiency. Operators only need to use simple tools to rotate the screws to quickly adjust the positions of the limiting space 201 and the limiting roller 2.

[0069] Screw drives have high transmission efficiency, enabling rapid conversion of rotary motion into linear motion. In practical operation, rotating the screw allows the moving part 4 and the adjusting part 5 to quickly move to the desired position. For example, when a large adjustment is needed to the limiting space 201, rotating the first adjusting screw 6 can quickly change the distance between the two moving parts 4; while for fine adjustments, rotating the second adjusting screw 7 can also quickly and accurately adjust the position of the adjusting part 5, meeting the speed and precision requirements of different adjustment scenarios.

[0070] The threaded connection structure between the first adjusting screw 6 and the second adjusting screw 7 and the moving part 4 and the adjusting part 5 provides stable adjustment support. During the operation of the device, even if subjected to external forces such as vibration and impact, the tight fit between the screw and the threaded hole ensures that the moving part 4 and the adjusting part 5 will not easily shift, ensuring that the position of the limiting roller 2 and the size of the limiting space 201 remain stable at all times.

[0071] The smoothness and reliability of the lead screw drive help reduce wear on components such as the moving part 4, adjusting part 5, and limiting roller 2 during the adjustment process. Because the lead screw can transmit power evenly, the force on each component is uniform during movement, reducing the risk of wear and damage caused by excessive local force on the components.

[0072] Furthermore, it also includes a wear-resistant sleeve 8, which is disposed on the limiting roller 2 and the reversing roller 3.

[0073] In this embodiment, during the operation of the pickling disc shear, the edge wire continuously contacts and rubs against the limiting roller 2 and the reversing roller 3. The wear-resistant sleeve 8, installed on these rollers, effectively withstands this friction as it is the part directly in contact with the edge wire, thus reducing wear on the rollers themselves. The wear-resistant sleeve 8 is relatively independent of the rollers; when it wears out due to prolonged use, it can simply be removed from the limiting roller 2 or the reversing roller 3 and replaced with a new one, without needing to replace the entire roller. This greatly simplifies the maintenance process and reduces maintenance costs and time. For example, in routine maintenance, operators can quickly replace the wear-resistant sleeve 8, allowing the equipment to return to normal operation as soon as possible and reducing downtime caused by equipment maintenance.

[0074] Furthermore, the wear-resistant sleeve 8 includes a first sleeve body 801, which is disposed on the limiting roller 2 and the reversing roller 3, and there are several of them arranged in sequence. The first sleeve body 801 has a first connecting part 802 and a first connecting groove 803. After the first connecting part 802 is inserted into the first connecting groove 803 of an adjacent first sleeve body 801, the two adjacent first sleeve bodies 801 are connected. The second sleeve body 804 is disposed on the limiting roller 2 and the reversing roller 3, and there are several of them arranged in sequence. The second sleeve body 804 has a second connecting part 805 and a second connecting groove 806. After the second connecting part 805 is inserted into the second connecting groove 806 of an adjacent second sleeve body 804, the two adjacent second sleeve bodies 804 are connected. The outer surfaces of the first sleeve body 801 and the second sleeve body 804 form a columnar wear-resistant surface 807.

[0075] In this embodiment, the wear-resistant sleeve 8 is arranged in a manner where a first sleeve body 801 and a second sleeve body 804 are arranged sequentially, and they are connected by their respective connecting parts and connecting grooves. The first connecting part 802 of the first sleeve body 801 can be inserted into the first connecting groove 803 of the adjacent first sleeve body 801, and the second connecting part 805 of the second sleeve body 804 can be inserted into the second connecting groove 806 of the adjacent second sleeve body 804. This modular assembly method allows the wear-resistant sleeve 8 to be flexibly assembled according to the length of the limiting roller 2 and the reversing roller 3, the actual condition of the edge yarn, and different production needs.

[0076] Because the edge wires may experience varying degrees of wear at the points of contact with the limiting roller 2 and the reversing roller 3 during transmission, this flexibly assembled wear-resistant sleeve 8 structure allows for localized adjustments to address different wear conditions. If a certain area is severely worn, only the corresponding first sleeve body 801 or second sleeve body 804 can be replaced, without replacing the entire wear-resistant sleeve 8. This improves the adaptability of the wear-resistant sleeve 8 to different working conditions and further reduces maintenance costs.

[0077] After the first set of bodies 801 and the second set of bodies 804 are assembled, their outer surfaces form a cylindrical wear-resistant surface 807. This cylindrical wear-resistant surface provides continuous and uniform support and guidance for the edge wires, ensuring that the edge wires are in full contact with the wear-resistant surface during transmission, reducing stress concentration, and lowering the risk of localized wear on the edge wires. At the same time, the cylindrical structure makes the movement of the edge wires on the roller body smoother, reducing jamming and vibration caused by uneven surfaces, improving the stability of edge wire transmission, and thus reducing the possibility of edge wire breakage.

[0078] Adjacent sleeves are tightly connected via connecting parts and connecting grooves, enhancing the stability of the entire wear-resistant sleeve 8 structure. During continuous friction between the edge wire and the wear-resistant sleeve 8, this tightly connected structure effectively resists the impact and vibration caused by friction, preventing loosening or displacement between the sleeves and ensuring that the wear-resistant sleeve 8 maintains a good working condition, thus extending its service life. For example, when the pickling and rolling disc shear operates at high speed, generating significant friction and impact between the edge wire and the wear-resistant sleeve 8, the stable structure ensures the normal operation of the wear-resistant sleeve 8 without affecting the transmission of the edge wire.

[0079] The connection between the first set 801 and the second set 804 is simple and intuitive. During installation, simply align the connecting part with the connecting groove and insert it; no complex tools or specialized skills are required. This allows operators to quickly complete the installation of the wear-resistant sleeve 8, reducing equipment installation and debugging time. For example, when initially installing or replacing the wear-resistant sleeve 8, operators can quickly assemble each sleeve onto the limit roller 2 and the reversing roller 3, improving work efficiency.

[0080] Because the wear-resistant sleeve 8 is composed of multiple independent sleeve bodies, maintenance personnel can easily inspect each sleeve body during maintenance, promptly identifying worn or damaged parts. Furthermore, replacing a single sleeve body is simple, eliminating the need to disassemble and replace the entire wear-resistant sleeve 8, thus reducing the difficulty and workload of maintenance. This helps in the timely detection and resolution of problems, ensuring the normal operation of the equipment and reducing equipment failures and downtime caused by improper maintenance.

[0081] Furthermore, both the outermost first set 801 and the second set 804 have a connecting end 808, which is used to connect the first set 801 and the second set 804.

[0082] In this embodiment, the connecting end 808 ensures a stable connection between the outermost first sleeve 801 and the second sleeve 804. This connection effectively prevents swaying or displacement caused by the lack of constraint on the outer sleeve during edge wire transmission. For example, when the edge wire passes through the limiting roller 2 and the reversing roller 3 at high speed, it may exert a lateral force on the wear-resistant sleeve. The connecting end 808 ensures that the outermost sleeves are tightly connected to jointly resist this external force, preventing the overall structure of the wear-resistant sleeve from loosening, thereby maintaining the stability of edge wire transmission and reducing the risk of edge wire breakage due to instability of the wear-resistant sleeve.

[0083] When a portion of the wear-resistant bushing wears out and needs replacement, the connecting end 808 facilitates the removal of the outermost bushing. Since the connecting end 808 connects to the outermost bushing, replacement can be achieved simply by disconnecting the connecting end 808, allowing for easy removal of the bushing to be replaced without affecting the connections of other bushings. This is significant for quickly repairing wear-resistant bushings, reducing maintenance costs, and minimizing downtime. For example, when the outermost bushing is severely worn due to prolonged friction with the edge threads, it can be quickly removed and replaced with a new bushing without requiring extensive disassembly and reassembly of the entire wear-resistant bushing.

[0084] Furthermore, it also includes a winding machine, which is located on one side of the frame 1 and is used for collecting edge yarn.

[0085] In this embodiment, the main function of the winding machine is to collect the edge wires. After the acid-rolling disc shear has finished cutting and processing the edge wires, they need to be collected and stored in an orderly manner. The winding machine can neatly wind the edge wires onto the reel. This not only facilitates the subsequent processing and storage of the edge wires, but also prevents them from being scattered and piled up in the production environment, reducing safety hazards. During the production process, if the edge wires are not collected, they will be scattered on the ground or around the equipment, which may cause personnel to trip or be caught in other equipment. The winding machine can collect the edge wires in an orderly manner.

[0086] The winding machine ensures continuous collection of edge wire, allowing the pickling and rolling disc shearing process to continue uninterruptedly without frequent production stoppages to address edge wire accumulation. As edge wire is continuously generated, the winding machine continuously winds it up, ensuring that edge wire does not clog the production line and thus improving the efficiency of the entire production process. For example, during high-speed production, edge wire can be continuously collected by the winding machine, preventing accumulation from affecting the transmission and processing of subsequent edge wire and ensuring production continuity.

[0087] Furthermore, it also includes a fastening bolt 10, which passes through the connecting end 808 and is used to fix the first body 801 and the second body 804.

[0088] In this embodiment, the fastening bolt 10 securely connects the first sleeve 801 and the second sleeve 804 through the connecting end 808, making them form an integral structure. During the continuous friction between the edge thread and the wear-resistant sleeve 8, especially when subjected to large frictional and impact forces, the fastening bolt 10 can prevent relative displacement or loosening between the first sleeve 801 and the second sleeve 804.

[0089] Furthermore, both the first body 801 and the second body 804 have cast iron layers 809 and wear-resistant layers 810 arranged from the inside out.

[0090] In this embodiment, the cast iron layer 809 serves as the inner layer, providing basic structural strength for the wear-resistant sleeve. Cast iron possesses high compressive strength and a certain degree of toughness, enabling it to withstand the pressure and impact generated during the transmission of the edge wire. For example, when the edge wire passes through the limiting roller 2 and the reversing roller 3, it applies pressure to the wear-resistant sleeve. The cast iron layer 809 effectively supports the entire wear-resistant sleeve structure, preventing deformation or damage and ensuring the basic structural integrity of the wear-resistant sleeve.

[0091] The wear-resistant layer 810, located on the outer side, is in direct contact with the edge wires and is specifically designed to resist friction from them. The wear-resistant layer 810 exhibits excellent wear resistance, significantly reducing wear between the edge wires and the wear-resistant sleeve, thus extending the service life of the wear-resistant sleeve. Even with continuous friction from the edge wires during long-term use, the wear-resistant layer 810 effectively protects the inner cast iron layer 809, preventing it from losing its structural support due to wear.

[0092] This layered structure, from the inside out, allows the first body 801 and the second body 804 to combine the advantages of different materials. The cast iron layer 809 and the wear-resistant layer 810 work together to ensure the structural strength of the wear-resistant sleeve while minimizing the impact of wear on the sleeve. For example, when dealing with high-strength, high-hardness edge wires, the strength provided by the cast iron layer 809 can withstand larger loads, while the wear-resistant layer 810 is responsible for protecting the entire structure, ensuring it maintains good performance even under harsh working conditions.
