Especially in the head section, tail section and middle section areas of the steel plate, there are steel plates that do not meet the product quality requirements. These quality problems may stem from various factors such as raw material defects, improper adjustment of process parameters, equipment wear, etc., resulting in the final product not meeting the established quality standards.

[0003] According to the technical capabilities of the current steel coil slitting production line equipment, for these steel plates that do not meet the quality requirements, they need to be disposed of as soon as possible. During disposal, the production line needs to be stopped, the steel plates that do not meet the requirements are left on the conveyor platform, and the operator commands the overhead crane to use a lifting tool to lift the steel plates out of the production line for storage, and then resume production. This waste disposal method has low efficiency, not only greatly reduces the continuous operation efficiency of the production line, increases production costs, but also increases the burden on the operator and has potential safety hazards. Specifically, the shutdown operation interrupts the smoothness of the production line, resulting in a decrease in production capacity; at the same time, the operator needs to frequently command the overhead crane to use a lifting tool to remove the unqualified steel plates from the production line and store them properly. This process is time-consuming and laborious, and places high requirements on the operator's professional skills and concentration. Summary of the Utility Model

[0013] In some possible implementation manners, a plurality of roller bearings for supporting waste are provided on the support frame, the horizontal guiding frame, and the movable guiding frame.

[0014] In some possible implementation manners, the support frame is inserted on the rotating shaft at the upper part of the swing rod.

[0015] Due to the adoption of the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0016] 1. Set up a push-out unit, drive the lifting mechanism through the power unit to lift the steel plate scrap that does not meet the quality requirements on the roller conveyor platform, and drive the sliding frame to enable the push plate to push the scrap from the platform. The scrap pushed out of the platform is exported to the required drop point through the material export unit. The automatic horizontal push greatly shortens the time for scrap removal, improves the efficiency of scrap disposal on the platform, reduces the production capacity loss caused by downtime, and reduces the labor intensity and the risk of safety accidents.

[0017] 2. The push-out unit is equipped with a double lifting mechanism to provide stronger support when bearing heavy steel plates, making it more stable and reliable when pushing out steel plates; the lifting mechanism will be moved to a low position when not in use to avoid interfering with normal production, and when the waste is raised to a high position, it can be smoothly moved out of the platform.

[0018] 3. The structural setting of the push-out unit can drive the push plate to move horizontally by pushing the sliding frame through the power cylinder. At the same time, as the sliding frame moves, the roller climbs up the slide bar and rolls on it. During the rising process of the roller, the middle connecting rod drives the rocker arm to rotate around the hinge point on the fixed frame, so that the support frame lifts the waste, and the waste is pushed out of the platform by the push plate that moves with the sliding frame. The lifting and pushing out of the waste are achieved through the same power source, which reduces space occupancy and improves the working efficiency of the mechanism.

[0019] 4. The structural setting of the sliding frame provides good rigidity and stability, which can optimize the power output and make the movement of the sliding frame more stable and consistent.

[0020] 5. The fixed frame is provided with two fixed rails slidably connected to the slide bar, which provides a stable support for the slide bar and prevents the slide bar from shaking or shifting during operation, thereby ensuring the stability of the equipment fixed on the fixed frame, and can reduce the impact of the vibration caused by the operation of the equipment on the ejection unit, further improving the stability and working accuracy of the equipment.

[0021] 6. The movable lead-out frame and the horizontal lead-out frame of the blanking lead-out unit are hingedly designed, so that the movable lead-out frame can be adjusted or displaced to a certain angle relative to the horizontal lead-out frame. This design increases the flexibility of the lead-out unit and can better meet the needs of exporting waste of different sizes. With the slide bar and travel switch, the movable lead-out frame is pushed to the optimal angle, so that the waste can slide accurately and quickly to the designated position.

[0022] 7. The movable export rack is provided with a chute that slidably cooperates with the sliding rod, reducing the direct contact and friction between the sliding rod and the movable export rack, thus ensuring that the waste can be exported smoothly and steadily; reducing the direct contact between the sliding rod and other parts of the movable export rack, thereby reducing the mechanical wear of the movable export rack and extending its service life.

[0023] 8. The roller bearings are provided, reducing the direct contact between the waste and the support frame, the horizontal export rack and the movable export rack during the movement process, thus reducing the wear caused by friction. The rolling action of the roller bearings enables the waste to move more smoothly during the export process, reducing the stagnation or jamming phenomenon caused by resistance, and helping to protect the surface quality and integrity of the waste.

[0024] 9. The design of inserting the support frame on the swing rod rotating shaft facilitates quick disassembly, assembly and maintenance. When cleaning, inspecting or replacing components are needed, the relevant components can be operated more quickly, and can also be adjusted as needed to adapt to waste materials of different sizes and weights.

[0035] The present utility model will be further described in detail below in conjunction with the embodiments of the attached drawings:

[0036] Figure 1 and Figure 2 The waste removal device for the steel plate roller conveyor platform as shown, this device is mainly applied to the production line where hot-rolled finished steel coils are leveled into sheet products. It includes a pushing unit 2 and a blank discharging guiding unit 3. The pushing unit 2 is arranged below the roller conveyor platform 1 to realize the removal of waste under the premise of not interfering with the normal steel plate conveying process; the blank discharging guiding unit 3 is located in the pushing direction of the pushing unit 2 and is installed outside the edge of the roller conveyor platform 1. The pushing direction is perpendicular to the conveying direction of the roller conveyor platform 1. After the waste steel plate is pushed out by the pushing unit 2, it slides along the blank discharging guiding unit 3 to the collection area. A single set of pushing unit 2 and the corresponding blank discharging guiding unit 3 can be arranged on the roller conveyor platform 1, or multiple sets of pushing units 2 and blank discharging guiding units 3 can be arranged at intervals along the conveying direction of the roller conveyor platform 1.

[0037] In some possible embodiments, such as Figures 3 to 7As shown in the figure, the pushing unit 2 includes a fixed frame, a sliding frame, a lifting mechanism 11, a pushing plate 10 and a power unit. Among them, the fixed frame is fixedly installed under the roller conveyor platform 1 to provide a stable support foundation. A horizontally arranged fixed rail 9 is provided on the fixed frame to guide the smooth sliding of the sliding frame. The sliding frame includes three slide bars 7 parallel to the fixed rail 9 and two cross bars 6 connecting these slide bars 7. Each slide bar 7 is slidably connected between two opposite fixed rails 9. The power unit is a power cylinder 5 arranged directly below the middle slide bar 7. The power cylinder 5 uses a hydraulic cylinder, and the power cylinder 5 in other embodiments can use an air cylinder, an electric cylinder, etc. The power cylinder 5 is horizontally arranged, and its piston rod extends towards the side where the blanking and discharging unit 3 is located. The extending end is connected to the cross bar 6 close to the blanking and discharging unit 3, and the cylinder body tail at the other end is installed on the power cylinder mounting seat 4. A pushing plate 10 is installed on the sliding frame. The pushing plate 10 is a component that directly contacts the waste steel plate and pushes it out. Preferably, the pushing plate 10 is installed on the middle slide bar 7 and away from the pushing end of the slide bar 7. A single pushing unit 2 has two lifting mechanisms 11. The lifting mechanisms 11 are arranged between two adjacent conveying rollers of the roller conveyor platform 1. The lowest position where the lifting mechanism 11 descends is lower than the top end of the conveying roller, and the highest position where the lifting mechanism 11 rises is higher than the roller conveyor platform 1. The lifting mechanism 11 includes a support frame 12, a swing rod 17, an intermediate connecting rod 15 and a roller 16. The support frame 12 is hinged to the fixed frame through two parallel swing rods 17 to form a stable swinging and lifting structure. The support frame 12 has two symmetrically connected rod bodies. A plurality of roller bearings 13 protruding upward from the rod bodies are installed between the two rod bodies. Two parallel swing rods 17 are connected to the outside of both rod bodies. The opposite two swing rods 17 are respectively connected by a hinge shaft in the middle. An intermediate connecting rod 15 is hinged in the middle of the hinge shaft, and a roller 16 is installed below the intermediate connecting rod 15. The roller 16 can roll on the slide bar 7 of the sliding frame. It is worth mentioning that the top surface of the slide bar 7 is higher than the top surface of the fixed rail 9 of the fixed frame, and an inclined guiding surface 7-1 is designed at one end close to the blanking and discharging unit 3 to facilitate the smooth guiding of the roller 16 during the lifting process. In addition, as Figure 6 and Figure 7 shown, a sinking limit groove 9-1 is also provided on the fixed rail 9 of the fixed frame. The groove has an inclined slope opposite to the inclined direction of the inclined guiding surface 7-1, which is used to reset and lock the roller 16 when the lifting mechanism 11 descends. For the convenience of disassembly, assembly and maintenance, the rotating shaft connecting the upper part of the support frame 12 and the swing rod 17 is a plug-in structure. The support frame 12 has a plug board 14. The plug board 14 is provided with a U-shaped socket opening downward, and the U-shaped socket is inserted into the rotating shaft at the upper part of the swing rod 17. A travel switch 8 for coordinating with the stroke of the power cylinder 5 to control the waste blanking position is also provided at the end of the fixed rail 9.

[0038] As Figure 1 、 Figure 2 、 Figure 8 and Figure 9As shown, the blanking export unit 3 is responsible for receiving and exporting the waste material 18 pushed out by the pushing unit. It includes a horizontal export frame 19 and a movable export frame 20. One end of the horizontal export frame 19 is fixed to the outer edge of the roller conveyor platform 1, serving as the initial export path for the waste material 18 steel plate. Its design is stable and smooth to ensure that the waste material 18 steel plate can smoothly slide out of the conveyor roller. One end of the movable export frame 20 is hinged to the horizontal export frame 19, and the other end hangs downward. A chute 21 is designed on the side of the movable export frame 20 facing the sliding rod 7 for sliding cooperation with the sliding rod 7 to jack up and form an inclined angle. Preferably, the horizontal export frame 19 and the movable export frame 20 are also provided with a plurality of roller bearings 13 for supporting the waste material 18, and the setting structure refers to the support frame 12. The inclination angle of the movable export frame 20 is adjusted according to the width and pushing amount of the waste material 18 steel plate to ensure that the waste material 18 can accurately fall into the designated collection area.

[0039] When the waste removal device is in a non-operating state, the lifting mechanism 11 of the pushing unit 2 is at the initial position at the lowest level. At this time, the roller 16 is placed in the sinking limit groove 9-1 of the fixed frame, while the sliding frame and the push plate 10 are located away from the blanking export unit 3, ensuring safety and not obstructing other operations. When it is necessary to remove the waste 1 on the roller conveyor platform 1 from the platform, the power cylinder 5 is activated, and the power cylinder 5 horizontally drives the sliding frame to move smoothly towards the blanking export unit 3. Since the top surface of the sliding rod 7 is higher than the fixed frame, and an inclined guiding surface 7-1 is provided at one end of the sliding rod 7 close to the blanking export unit 3, the movement of the sliding frame will drive the sliding rod 7 thereon towards the lifting mechanism 11. As the sliding frame moves, the roller 16 gradually comes into contact with the sliding rod 7 and starts to roll thereon. During the process of the roller 16 rising along the sliding rod, it simultaneously drives the swing rod 17 to rotate around the hinge point on the fixed frame. In this process, the intermediate connecting rod 15, as a key part of the linkage mechanism, ensures the coordinated movement between the swing rod 17 and the roller 16. The roller 16 continuously rolls horizontally on the sliding rod 7, keeping the support frame of the lifting mechanism 11 at the highest position. In this way, the steel plate waste 1 can be lifted above the roller conveyor platform 1. At the same time, as the push plate 10 moves along with the sliding rod 7, the waste 18 is laterally pushed out of the roller conveyor platform 1. The blanking export unit 3 receives the pushed waste 18. The horizontal export frame 19 serves as a bridge for the waste 18 to completely break away from the roller conveyor platform 1 and transition to the designated collection area, and its design ensures that the waste can move smoothly without obstruction. When the waste 18 steel plate moves to the end along the horizontal export frame 19, when the moving sliding frame touches the movable guiding frame 20, it pushes the movable guiding frame 20 to rotate upwards to a suitable inclination angle matching the width and the pushing amount of the waste 18 steel plate. Keeping the power cylinder 5 stationary, the waste 18 steel plate slides down along the inclined movable guiding frame 20 to the designated collection area under the action of gravity. Subsequently, the power cylinder 5 is driven in the reverse direction to make the sliding frame smoothly retract in the opposite direction. During the retraction process, the sliding rod 7 disengages from the movable guiding frame 20, and the movable guiding frame 20 resets to the hanging state. At the same time, when the roller 16 of the lifting mechanism 11 slides down along the inclined guiding surface 7-1 of the sliding rod 7 of the sliding frame, it drives the swing rod 17 to rotate in the reverse direction, causing the lifting mechanism 11 to gradually descend, and the roller 16 gradually separates from the sliding rod 7 until it completely disengages from the sliding rod 7 and returns to the sinking limit groove 9-1 of the fixed frame. At this time, the lifting mechanism 11 resets to the initial position.

[0040] This waste removal device has been realized for single-group and multi-group flexible combination use in the applicant's slitting production line of the hot rolling mill, and can quickly push waste plates within a certain length and width range away from the conveying roller table, enabling the production line to quickly enter the next production cycle, reducing the personnel operation and the use of the overhead crane in this process, and improving the on-site production efficiency.
